Pregnant patients with COVID-19 infections were more likely to experience severe disease if they had preexisting comorbidities, such as chronic hypertension, asthma, or pregestational diabetes, according to findings from a new study presented at the meeting sponsored by the Society for Maternal-Fetal Medicine.

The study included outcomes for the largest multistate cohort of pregnant patients with COVID-19 outside of what the Centers for Disease Control and Prevention is tracking. Its findings also mirrored those of a multicenter, retrospective study in Washington state, published in the American Journal of Obstetrics & Gynecology. That study also found that pregnant patients hospitalized for COVID-19 were more likely to have comorbidities, and both studies found an increased likelihood of preterm birth among pregnant patients with severe or critical disease.
 

Disease severity linked to risk of perinatal complications

In the abstract presented at the SMFM meeting, more severe disease was associated with older age and a higher median body mass index, as seen in the general population, but the researchers found no differences in disease severity occurred by race or ethnicity, Torri D. Metz, MD, of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network, told attendees of the conference. The researchers also found that perinatal complications were more prevalent in those with severe or critical COVID-19 disease but not in those with mild or moderate disease. Vertical COVID-19 transmission from mother to child was rare.

The observational study included all patients who had a singleton pregnancy, had a positive SARS-CoV-2 test, and delivered between March 1 and July 31, 2020, at one of the 33 U.S. hospitals in the NICHD Maternal-Fetal Medicine Units Network, spread across 14 states. The researchers used electronic medical records to determine incidence of cesarean delivery, postpartum hemorrhage, hypertensive disorders of pregnancy, preterm birth (less than 37 weeks), maternal death, infant death, and positive infant COVID-19 test. They tracked mothers through 6 weeks post partum and newborns through delivery hospitalization.

Of 1,291 patients in the cohort, 1,219 received their first positive COVID-19 test during pregnancy. The others tested positive while in the hospital for delivery or within a month and a half after discharge. Limiting their analysis to those who developed COVID-19 while pregnant prior to delivery, nearly half (47%) were asymptomatic.

The disease was mild in 27%, moderate in 14%, severe in 8%, and critical in 4%. The researchers used the National Institutes of Health classifications for severity and included deaths in the critical group. The most common symptom was a cough, reported by a third of the patients (34%). Four of six maternal deaths that occurred were caused by COVID-19.

Compared with an average age of 28 in those without symptoms, the mean age was 29 in those with mild/moderate disease and 30 in those with severe/critical disease (P = .006). Similarly, the mean BMI was 28.3 in asymptomatic patients, 29 in those with mild/moderate disease, and 32.3 in those with severe/critical disease (P < .001). Despite a diverse cohort – 53% Hispanic, 23% Black, and 15% White – the researches found no racial/ethnic trends in disease severity.

Patients who had asthma, chronic obstructive pulmonary disorder, pregestational diabetes, chronic hypertension, chronic liver disease, or a seizure disorder were all significantly more likely to have critical/severe disease than mild/moderate disease, and more likely to have mild/moderate disease than asymptomatic (P values ranged from < .001 to .02).

The mothers with critical or severe illness were 1.6 times more likely to have cesarean births and to have hypertensive disorders of pregnancy, and they were twice as likely to have postpartum hemorrhage (P < .001; P = .007). Those with mild or moderate disease, however, had no increased risks for perinatal complications over asymptomatic patients.

Critical or severe illness was also associated with more than triple the risk of preterm birth (adjusted risk ratio, 3.6; P < .001). Newborns of mothers with critical or severe illness also had three times greater risk of neonatal ICU admission (ARR, 3.1; P <. 001) and weighed an average 385 g less than newborns of asymptomatic mothers. COVID-19 rate among infants was only 1% during delivery hospitalization.

Since the study cutoff was July 30 and COVID infections only became prevalent in March, the researchers were unable to evaluate women for outcomes resulting from COVID infections in early pregnancy, such as congenital anomalies or early miscarriage, Dr. Metz said. In addition, since many of the sites are urban centers, the data may not be generalizable to rural areas.

Peter S. Bernstein, MD, MPH, of Montefiore Medical Center, New York, asked whether the increased cesarean deliveries and preterm births in the group of women with severe disease were caused by usual obstetric causes or the treatment of COVID-19 infection. Dr. Metz said the vast majority of preterm deliveries were indicated, but only a small proportion were induced for COVID-19 alone. “A lot had hypertensive disorders of pregnancies or PPROM, so it’s partly driven by the infection itself but also partly driven by some of those perinatal complications,” she said.
 

 

 

Similar findings in Washington

In the Washington study, among 240 pregnant patients with confirmed COVID-19 infection between March 1 and July 30, 2020, 1 in 11 developed severe or critical disease, and 1 in 10 were hospitalized. The pregnant patients had more than triple the risk of hospitalization compared with adults of similar ages in the general population (10% vs. 2.8%; rate ratio, 3.5). Similar to the multistate NICHD study, women were more likely to be hospitalized if they had asthma, hypertension, type 2 diabetes, autoimmune disease, or class III obesity.

Three mothers died of COVID-19, resulting in a case fatality rate 13.6 times greater than nonpregnant patients with COVID-19 in the general population. The absolute difference in the rate was 1.2%. As seen in the NICHD study, preterm birth was more common in mothers with severe or critical COVID-19. Nearly half (45.4%) of mothers with severe or critical COVID-19 delivered preterm compared to 5.2% in those with mild COVID-19 (P < .001).

“Our finding that deaths in pregnant patients contributed disproportionately to deaths from COVID-19 among 20- to 39-year-olds in Washington state is similar to what was observed during the influenza A virus H1N1 2009 pandemic,” Erica M. Lokken, PhD, MS, of the departments of global health and ob.gyn. at the University of Washington, Seattle, and colleagues wrote in the Washington study. But they noted that it took 8 months into the pandemic before pregnant patients were identified as a high-risk group for COVID-19.

“Given the similarity in clinical course between COVID-19 and IAV H1N1 2009 with an increased risk for mortality during pregnancy and the postpartum period, we strongly recommend that pregnant patients should be considered a high-risk population to novel highly pathogenic respiratory viruses until proven otherwise by population-based studies with good ascertainment of pregnancy status,” they wrote.

Judette Louis, MD, MPH, associate professor of ob.gyn. and department chair at the University of South Florida, Tampa, said in an interview that the findings in these studies were fairly expected, but it’s important to have data from such a large cohort as the one presented at SMFM.

“It confirmed that those who had severe disease were more likely to have chronic medical conditions, mirroring what we saw in the general population who isn’t pregnant,” Dr. Louis said. “I thought this was very crucial because as pregnant women are trying to decide whether they should get the COVID vaccine, this provides support to say that if you’re pregnant, you’re more likely to have severe disease [if you have] other chronic medical conditions.”

The findings also confirm the importance of pregnant people taking precautions to avoid infection.

“Even though these individuals are, as a group, in an age cohort that mostly has asymptomatic disease, for some of them, it results in severe disease and even maternal death,” she said. “They should still take it seriously if they’re pregnant.”

The SMFM abstract study was funded by the NICHD. The Washington study was funded by the University of Washington Population Health Initiative, the National Institutes of Health, and philanthropic gift funds. One coauthor of the Washington study is on a Pfizer and GlaxoSmithKline advisory board for immunizations. No other authors or individuals interviewed reported any disclosures.

MIS-C follow-up proves challenging across pediatric hospitals

Thu, 08/26/2021 - 15:50

The discovery of any novel disease or condition means a steep learning curve as physicians must develop protocols for diagnosis, management, and follow-up on the fly in the midst of admitting and treating patients. Medical society task forces and committees often release interim guidance during the learning process, but each institution ultimately has to determine what works for them based on their resources, clinical experience, and patient population.

But when the novel condition demands the involvement of multiple different specialties, the challenge of management grows even more complex – as does follow-up after patients are discharged. Such has been the story with multisystem inflammatory syndrome in children (MIS-C), a complication of COVID-19 that shares some features with Kawasaki disease.

The similarities to Kawasaki provided physicians a place to start in developing appropriate treatment regimens and involved a similar interdisciplinary team from, at the least, cardiology and rheumatology, plus infectious disease since MIS-C results from COVID-19.

“It literally has it in the name – multisystem essentially hints that there are multiple specialties involved, multiple hands in the pot trying to manage the kids, and so each specialty has their own kind of unique role in the patient’s care even on the outpatient side,” said Samina S. Bhumbra, MD, an infectious disease pediatrician at Riley Hospital for Children and assistant professor of clinical pediatrics at Indiana University in Indianapolis. “This isn’t a disease that falls under one specialty.”

Dr. Samina S. Bhumbra


By July, the American College of Rheumatology had issued interim clinical guidance for management that most children’s hospitals have followed or slightly adapted. But ACR guidelines could not address how each institution should handle outpatient follow-up visits, especially since those visits required, again, at least cardiology and rheumatology if not infectious disease or other specialties as well.

“When their kids are admitted to the hospital, to be told at discharge you have to be followed up by all these specialists is a lot to handle,” Dr. Bhumbra said. But just as it’s difficult for parents to deal with the need to see several different doctors after discharge, it can be difficult at some institutions for physicians to design a follow-up schedule that can accommodate families, especially families who live far from the hospital in the first place.

“Some of our follow-up is disjointed because all of our clinics had never been on the same day just because of staff availability,” Dr. Bhumbra said. “But it can be a 2- to 3-hour drive for some of our patients, depending on how far they’re coming.”

Many of them can’t make that drive more than once in the same month, much less the same week.

“If you have multiple visits, it makes it more likely that they’re not showing up,” said Ryan M. Serrano, MD, a pediatric cardiologist at Riley and assistant professor of pediatrics at Indiana University. Riley used telehealth when possible, especially if families could get labs done near home. But pediatric echocardiograms require technicians who have experience with children, so families need to come to the hospital.

Dr. Ryan M. Serrano


Children’s hospitals have therefore had to adapt scheduling strategies or develop pediatric specialty clinics to coordinate across the multiple departments and accommodate a complex follow-up regimen that is still evolving as physicians learn more about MIS-C.
 

 

 

Determining a follow-up regimen

Even before determining how to coordinate appointments, hospitals had to decide what follow-up itself should be.

“How long do we follow these patients and how often do we follow them?” said Melissa S. Oliver, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University.

Dr. Melissa S. Oliver

“We’re seeing that a lot of our patients rapidly respond when they get appropriate therapy, but we don’t know about long-term outcomes yet. We’re all still learning.”

At Children’s Hospital of Philadelphia, infectious disease follows up 4-6 weeks post discharge. The cardiology division came up with a follow-up plan that has evolved over time, said Matthew Elias, MD, an attending cardiologist at CHOP’s Cardiac Center and clinical assistant professor of pediatrics at the University of Pennsylvania, Philadelphia.

Patients get an EKG and echocardiogram at 2 weeks and, if their condition is stable, 6 weeks after discharge. After that, it depends on the patient’s clinical situation. Patients with moderately diminished left ventricular systolic function are recommended to get an MRI scan 3 months after discharge and, if old enough, exercise stress tests. Otherwise, they are seen at 6 months, but that appointment is optional for those whose prior echos have consistently been normal.

Other institutions, including Riley, are following a similar schedule of 2-week, 6-week, and 6-month postdischarge follow-ups, and most plan to do a 1-year follow-up as well, although that 1-year mark hasn’t arrived yet for most. Most do rheumatology labs at the 2-week appointment and use that to determine steroids management and whether labs are needed at the 6-week appointment. If labs have normalized, they aren’t done at 6 months. Small variations in follow-up management exist across institutions, but all are remaining open to changes. Riley, for example, is considering MRI screening for ongoing cardiac inflammation at 6 months to a year for all patients, Dr. Serrano said.
 

The dedicated clinic model

The two challenges Riley needed to address were the lack of a clear consensus on what MIS-C follow-up should look like and the need for continuity of care, Dr. Serrano said.

Regular discussion in departmental meetings at Riley “progressed from how do we take care of them and what treatments do we give them to how do we follow them and manage them in outpatient,” Dr. Oliver said. In the inpatient setting, they had an interdisciplinary team, but how could they maintain that for outpatients without overwhelming the families?

“I think the main challenge is for the families to identify who is leading the care for them,” said Martha M. Rodriguez, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University. That sometimes led to families picking which follow-up appointments they would attend and which they would skip if they could not make them all – and sometimes they skipped the more important ones. “They would go to the appointment with me and then miss the cardiology appointments and the echocardiogram, which was more important to follow any abnormalities in the heart,” Dr. Rodriguez said.

After trying to coordinate separate follow-up appointments for months, Riley ultimately decided to form a dedicated clinic for MIS-C follow-up – a “one-stop shop” single appointment at each follow-up, Dr. Bhumbra said, that covers labs, EKG, echocardiogram, and any other necessary tests.

“Our goal with the clinic is to make life easier for the families and to be able to coordinate the appointments,” Dr. Rodriguez said. “They will be able to see the three of us, and it would be easier for us to communicate with each other about their plan.”



The clinic began Feb. 11 and occurs twice a month. Though it’s just begun, Dr. Oliver said the first clinic went well, and it’s helping them figure out the role each specialty needs to play in follow-up care.

“For us with rheumatology, after lab values have returned to normal and they’re off steroids, sometimes we think there isn’t much more we can contribute to,” she said. And then there are the patients who didn’t see any rheumatologists while inpatients.

“That’s what we’re trying to figure out as well,” Dr. Oliver said. “Should we be seeing every single kid regardless of whether we were involved in their inpatient [stay] or only seeing the ones we’ve seen?” She expects the coming months will help them work that out.

Texas Children’s Hospital in Houston also uses a dedicated clinic, but they set it up before the first MIS-C patient came through the doors, said Sara Kristen Sexson Tejtel, MD, a pediatric cardiologist at Texas Children’s. The hospital already has other types of multidisciplinary clinics, and they anticipated the challenge of getting families to come to too many appointments in a short period of time.

Dr. Sara Kristen Sexson Tejtel


“Getting someone to come back once is hard enough,” Dr. Sexson Tejtel said. “Getting them to come back twice is impossible.”

Infectious disease is less involved at Texas Children’s, so it’s primarily Dr. Sexson Tejtel and her rheumatologist colleague who see the patients. They hold the clinic once a week, twice if needed.

“It does make the appointment a little longer, but I think the patients appreciate that everything can be addressed with that one visit,” Dr. Sexson Tejtel said. “Being in the hospital as long as some of these kids are is so hard, so making any of that easy as possible is so helpful.” A single appointment also allows the doctors to work together on what labs are needed so that children don’t need multiple labs drawn.

At the appointment, she and the rheumatologist enter the patient’s room and take the patient’s history together.

“It’s nice because it makes the family not to have to repeat things and tell the same story over and over,” she said. “Sometimes I ask questions that then the rheumatologist jumps off of, and then sometimes he’ll ask questions, and I’ll think, ‘Ooh, I’ll ask more questions about that.’ ”

In fact, this team approach at all clinics has made her a more thoughtful, well-rounded physician, she said.

“I have learned so much going to all of my multidisciplinary clinics, and I think I’m able to better care for my patients because I’m not just thinking about it from a cardiac perspective,” she said. “It takes some work, but it’s not hard and I think it is beneficial both for the patient and for the physician. This team approach is definitely where we’re trying to live right now.”
 

 

 

Separate but coordinated appointments

A dedicated clinic isn’t the answer for all institutions, however. At Children’s Hospital of Philadelphia, the size of the networks and all its satellites made a one-stop shop impractical.

“We talked about a consolidated clinic early on, when MIS-C was first emerging and all our groups were collaborating and coming up with our inpatient and outpatient care pathways,” said Sanjeev K. Swami, MD, an infectious disease pediatrician at CHOP and associate professor of clinical pediatrics at the University of Pennsylvania. But timing varies on when each specialist wants to see the families return, and existing clinic schedules and locations varied too much.

So CHOP coordinates appointments individually for each patient, depending on where the patient lives and sometimes stacking them on the same day when possible. Sometimes infectious disease or rheumatology use telehealth, and CHOP, like the other hospitals, prioritizes cardiology, especially for the patients who had cardiac abnormalities in the hospital, Dr. Swami said.

“All three of our groups try to be as flexible as possible. We’ve had a really good collaboration between our groups,” he said, and spreading out follow-up allows specialists to ask about concerns raised at previous appointments, ensuring stronger continuity of care.

“We can make sure things are getting followed up on,” Dr. Swami said. “I think that has been beneficial to make sure things aren’t falling through the cracks.”

CHOP cardiologist Dr. Elias said that ongoing communication, among providers and with families, has been absolutely crucial.

“Everyone’s been talking so frequently about our MIS-C patients while inpatient that by the time they’re an outpatient, it seems to work smoothly, where families are hearing similar items but with a different flair, one from infectious, one from rheumatology, and one from cardiology,” he said.

Children’s Mercy in Kansas City, Mo., also has multiple satellite clinics and follows a model similar to that of CHOP. They discussed having a dedicated multidisciplinary team for each MIS-C patient, but even the logistics of that were difficult, said Emily J. Fox, MD, a rheumatologist and assistant professor of pediatrics at the University of Missouri-Kansas City.

Instead, Children’s Mercy tries to coordinate follow-up appointments to be on the same day and often use telehealth for the rheumatology appointments. Families that live closer to the hospital’s location in Joplin, Mo., go in for their cardiology appointment there, and then Dr. Fox conducts a telehealth appointment with the help of nurses in Joplin.

“We really do try hard, especially since these kids are in the hospital for a long time, to make the coordination as easy as possible,” Dr. Fox said. “This was all was very new, especially in the beginning, but I think at least our group is getting a little bit more comfortable in managing these patients.”
 

 

 

Looking ahead

The biggest question that still looms is what happens to these children, if anything, down the line.

“What was unique about this was this was a new disease we were all learning about together with no baseline,” Dr. Swami said. “None of us had ever seen this condition before.”

So far, the prognosis for the vast majority of children is good. “Most of these kids survive, most of them are doing well, and they almost all recover,” Dr. Serrano said. Labs tend to normalize by 6 weeks post discharge, if not much earlier, and not much cardiac involvement is showing up at later follow-ups. But not even a year has passed, so there’s plenty to learn. “We don’t know if there’s long-term risk. I would not be surprised if 20 years down the road we’re finding out things about this that we had no idea” about, Dr. Serrano said. “Everybody wants answers, and nobody has any, and the answers we have may end up being wrong. That’s how it goes when you’re dealing with something you’ve never seen.”

Research underway will ideally begin providing those answers soon. CHOP is a participating site in an NIH-NHLBI–sponsored study, called COVID MUSIC, that is tracking long-term outcomes for MIS-C at 30 centers across the United States and Canada for 5 years.



“That will really definitely be helpful in answering some of the questions about long-term outcomes,” Dr. Elias said. “We hope this is going to be a transient issue and that patients won’t have any long-term manifestations, but we don’t know that yet.”

Meanwhile, one benefit that has come out of the pandemic is strong collaboration, Dr. Bhumbra said.

“The biggest thing we’re all eagerly waiting and hoping for is standard guidelines on how best to follow-up on these kids, but I know that’s a ways away,” Dr. Bhumbra said. So for now, each institution is doing what it can to develop protocols that they feel best serve the patients’ needs, such as Riley’s new dedicated MIS-C clinic. “It takes a village to take care of these kids, and MIS-C has proven that having a clinic with all three specialties at one clinic is going to be great for the families.”

Dr. Fox serves on a committee for Pfizer unrelated to MIS-C. No other doctors interviewed for this story had relevant conflicts of interest to disclose.

The discovery of any novel disease or condition means a steep learning curve as physicians must develop protocols for diagnosis, management, and follow-up on the fly in the midst of admitting and treating patients. Medical society task forces and committees often release interim guidance during the learning process, but each institution ultimately has to determine what works for them based on their resources, clinical experience, and patient population.

But when the novel condition demands the involvement of multiple different specialties, the challenge of management grows even more complex – as does follow-up after patients are discharged. Such has been the story with multisystem inflammatory syndrome in children (MIS-C), a complication of COVID-19 that shares some features with Kawasaki disease.

The similarities to Kawasaki provided physicians a place to start in developing appropriate treatment regimens and involved a similar interdisciplinary team from, at the least, cardiology and rheumatology, plus infectious disease since MIS-C results from COVID-19.

“It literally has it in the name – multisystem essentially hints that there are multiple specialties involved, multiple hands in the pot trying to manage the kids, and so each specialty has their own kind of unique role in the patient’s care even on the outpatient side,” said Samina S. Bhumbra, MD, an infectious disease pediatrician at Riley Hospital for Children and assistant professor of clinical pediatrics at Indiana University in Indianapolis. “This isn’t a disease that falls under one specialty.”

Dr. Samina S. Bhumbra


By July, the American College of Rheumatology had issued interim clinical guidance for management that most children’s hospitals have followed or slightly adapted. But ACR guidelines could not address how each institution should handle outpatient follow-up visits, especially since those visits required, again, at least cardiology and rheumatology if not infectious disease or other specialties as well.

“When their kids are admitted to the hospital, to be told at discharge you have to be followed up by all these specialists is a lot to handle,” Dr. Bhumbra said. But just as it’s difficult for parents to deal with the need to see several different doctors after discharge, it can be difficult at some institutions for physicians to design a follow-up schedule that can accommodate families, especially families who live far from the hospital in the first place.

“Some of our follow-up is disjointed because all of our clinics had never been on the same day just because of staff availability,” Dr. Bhumbra said. “But it can be a 2- to 3-hour drive for some of our patients, depending on how far they’re coming.”

Many of them can’t make that drive more than once in the same month, much less the same week.

“If you have multiple visits, it makes it more likely that they’re not showing up,” said Ryan M. Serrano, MD, a pediatric cardiologist at Riley and assistant professor of pediatrics at Indiana University. Riley used telehealth when possible, especially if families could get labs done near home. But pediatric echocardiograms require technicians who have experience with children, so families need to come to the hospital.

Children’s hospitals have therefore had to adapt scheduling strategies or develop pediatric specialty clinics to coordinate across the multiple departments and accommodate a complex follow-up regimen that is still evolving as physicians learn more about MIS-C.
 

 

 

Determining a follow-up regimen

Even before determining how to coordinate appointments, hospitals had to decide what follow-up itself should be.

“How long do we follow these patients and how often do we follow them?” said Melissa S. Oliver, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University.

“We’re seeing that a lot of our patients rapidly respond when they get appropriate therapy, but we don’t know about long-term outcomes yet. We’re all still learning.”

At Children’s Hospital of Philadelphia, infectious disease follows up 4-6 weeks post discharge. The cardiology division came up with a follow-up plan that has evolved over time, said Matthew Elias, MD, an attending cardiologist at CHOP’s Cardiac Center and clinical assistant professor of pediatrics at the University of Pennsylvania, Philadelphia.

Dr. Matthew Elias


Patients get an EKG and echocardiogram at 2 weeks and, if their condition is stable, 6 weeks after discharge. After that, it depends on the patient’s clinical situation. Patients with moderately diminished left ventricular systolic function are recommended to get an MRI scan 3 months after discharge and, if old enough, exercise stress tests. Otherwise, they are seen at 6 months, but that appointment is optional for those whose prior echos have consistently been normal.

Other institutions, including Riley, are following a similar schedule of 2-week, 6-week, and 6-month postdischarge follow-ups, and most plan to do a 1-year follow-up as well, although that 1-year mark hasn’t arrived yet for most. Most do rheumatology labs at the 2-week appointment and use that to determine steroids management and whether labs are needed at the 6-week appointment. If labs have normalized, they aren’t done at 6 months. Small variations in follow-up management exist across institutions, but all are remaining open to changes. Riley, for example, is considering MRI screening for ongoing cardiac inflammation at 6 months to a year for all patients, Dr. Serrano said.
 

The dedicated clinic model

The two challenges Riley needed to address were the lack of a clear consensus on what MIS-C follow-up should look like and the need for continuity of care, Dr. Serrano said.

Regular discussion in departmental meetings at Riley “progressed from how do we take care of them and what treatments do we give them to how do we follow them and manage them in outpatient,” Dr. Oliver said. In the inpatient setting, they had an interdisciplinary team, but how could they maintain that for outpatients without overwhelming the families?

“I think the main challenge is for the families to identify who is leading the care for them,” said Martha M. Rodriguez, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University. That sometimes led to families picking which follow-up appointments they would attend and which they would skip if they could not make them all – and sometimes they skipped the more important ones. “They would go to the appointment with me and then miss the cardiology appointments and the echocardiogram, which was more important to follow any abnormalities in the heart,” Dr. Rodriguez said.

After trying to coordinate separate follow-up appointments for months, Riley ultimately decided to form a dedicated clinic for MIS-C follow-up – a “one-stop shop” single appointment at each follow-up, Dr. Bhumbra said, that covers labs, EKG, echocardiogram, and any other necessary tests.

“Our goal with the clinic is to make life easier for the families and to be able to coordinate the appointments,” Dr. Rodriguez said. “They will be able to see the three of us, and it would be easier for us to communicate with each other about their plan.”



The clinic began Feb. 11 and occurs twice a month. Though it’s just begun, Dr. Oliver said the first clinic went well, and it’s helping them figure out the role each specialty needs to play in follow-up care.

“For us with rheumatology, after lab values have returned to normal and they’re off steroids, sometimes we think there isn’t much more we can contribute to,” she said. And then there are the patients who didn’t see any rheumatologists while inpatients.

“That’s what we’re trying to figure out as well,” Dr. Oliver said. “Should we be seeing every single kid regardless of whether we were involved in their inpatient [stay] or only seeing the ones we’ve seen?” She expects the coming months will help them work that out.

Texas Children’s Hospital in Houston also uses a dedicated clinic, but they set it up before the first MIS-C patient came through the doors, said Sara Kristen Sexson Tejtel, MD, a pediatric cardiologist at Texas Children’s. The hospital already has other types of multidisciplinary clinics, and they anticipated the challenge of getting families to come to too many appointments in a short period of time.

“Getting someone to come back once is hard enough,” Dr. Sexson Tejtel said. “Getting them to come back twice is impossible.”

Infectious disease is less involved at Texas Children’s, so it’s primarily Dr. Sexson Tejtel and her rheumatologist colleague who see the patients. They hold the clinic once a week, twice if needed.

“It does make the appointment a little longer, but I think the patients appreciate that everything can be addressed with that one visit,” Dr. Sexson Tejtel said. “Being in the hospital as long as some of these kids are is so hard, so making any of that easy as possible is so helpful.” A single appointment also allows the doctors to work together on what labs are needed so that children don’t need multiple labs drawn.

Research underway will ideally begin providing those answers soon. CHOP is a participating site in an NIH-NHLBI–sponsored study, called COVID MUSIC, that is tracking long-term outcomes for MIS-C at 30 centers across the United States and Canada for 5 years.



“That will really definitely be helpful in answering some of the questions about long-term outcomes,” Dr. Elias said. “We hope this is going to be a transient issue and that patients won’t have any long-term manifestations, but we don’t know that yet.”

Meanwhile, one benefit that has come out of the pandemic is strong collaboration, Dr. Bhumbra said.

“The biggest thing we’re all eagerly waiting and hoping for is standard guidelines on how best to follow-up on these kids, but I know that’s a ways away,” Dr. Bhumbra said. So for now, each institution is doing what it can to develop protocols that they feel best serve the patients’ needs, such as Riley’s new dedicated MIS-C clinic. “It takes a village to take care of these kids, and MIS-C has proven that having a clinic with all three specialties at one clinic is going to be great for the families.”

Dr. Fox serves on a committee for Pfizer unrelated to MIS-C. No other doctors interviewed for this story had relevant conflicts of interest to disclose.

Influenza-related maternal morbidity has more than doubled over 15 years

Despite slightly decreasing numbers of pregnant women hospitalized with influenza, the rate of morbidity among those who do have influenza has substantially increased from 2000 to 2015, likely due in part to an increase in comorbidities.

Maternal patients who have influenza while hospitalized for delivery are twice as likely to develop severe maternal morbidity than are those without influenza, according to findings from a new study presented at the Pregnancy Meeting, sponsored by the Society for Maternal-Fetal Medicine.

Pregnant women were also at substantially greater risk of sepsis or shock, needing mechanical ventilation, and acute respiratory distress syndrome. In fact, rates of overall severe maternal morbidity and of influenza-related complications have increased in maternal patients with influenza by more than 200% from 2000 to 2015.

“It was striking to see how the rate of delivery hospitalizations complicated by influenza has remained relatively stable with a small decline, but the rates of severe maternal morbidity were increasing and so markedly among those with influenza,” Timothy Wen, MD, MPH, a maternal-fetal medicine clinical fellow at the University of California, San Francisco, said in an interview. “The findings suggest that influenza may either be a contributor to rising rates of severe maternal morbidity or synergistically amplifying existing comorbidities to worsen outcomes,” he said during his presentation.

The increased risk of influenza complications in pregnant women became particularly apparent during the 2009-2010 H1N1 influenza pandemic. “Physiologic and immunologic changes predispose pregnant patients to higher risk for complications such as pneumonia, intensive care unit admission, and inpatient mortality,” Dr. Wen told attendees. But data have been scarce since H1N1.

The researchers conducted a cross-sectional analysis of delivery hospitalizations from 2000 to 2015 using the Nationwide Inpatient Sample, which includes about 20% of all U.S. inpatient hospitalizations from all payers. They looked at all maternal patients aged 15-54 who had a diagnosis of influenza. In looking at potential associations between influenza and morbidity, they adjusted their calculations for maternal age, payer status, median income, and race/ethnicity as well as the hospital factors of location, teaching status, and region. They also adjusted for a dozen clinical factors.

Of 62.7 million hospitalizations, 0.67% involved severe maternal mortality, including the following influenza complications:

  • 0.02% with shock/sepsis.
  • 0.01% needing mechanical ventilation.
  • 0.04% with acute respiratory distress syndrome.

The 182,228 patients with influenza represented a rate of 29 cases per 10,000 deliveries, and 2.09% of them involved severe maternal morbidity, compared to severe maternal morbidity in just 0.66% of deliveries without influenza.

When looking specifically at rates of shock/sepsis, mechanical ventilation, and acute respiratory distress syndrome, the data revealed similar trends, with substantially higher proportions of patients with influenza experiencing these complications compared to maternal patients without influenza. For example, 0.3% of patients with influenza developed shock/sepsis whereas only 0.04% of patients without influenza did. Acute respiratory distress syndrome was similarly more common in patients with flu (0.45% vs. 0.04%), as was the need for mechanical ventilation (0.09% vs. 0.01%).

During the 15-year study period, the rate of maternal hospitalizations with influenza infections declined about 1.5%, from 30 to 24 per 10,000 deliveries. But trends with severe maternal morbidity in patients with influenza went in the other direction, increasing more than 200% over 15 years, from 100 to 342 cases of severe maternal morbidity per 10,000 patients with influenza. An increase also occurred in patients without influenza, but it was more modest, a nearly 50% increase, from 53 to 79 cases per 10,000 hospitalizations.

From year to year, severe maternal morbidity increased 5.3% annually among hospitalizations with influenza – more than twice the rate of a 2.4% annual increase among hospitalizations without influenza.

The researchers found that influenza is linked to twice the risk of severe maternal morbidity (adjusted risk ratio [aRR] = 2.08, P < .01). There were similarly higher risks with influenza of sepsis/shock (aRR = 3.23), mechanical ventilation (aRR = 6.04), and acute respiratory distress syndrome (aRR = 5.76; all P < .01).

Among the possible reasons for the increase in influenza morbidity – despite a decrease in influenza infections in this population – is the increase in the medical complexity of the patient population, Dr. Wen said.

“Patients who are getting pregnant today likely have more comorbid conditions (chronic hypertension, obesity, pregestational diabetes mellitus, etc.) than they did decades prior,” Dr. Wen said. “Clinically, it means that we have a baseline patient population at a higher risk of susceptibility for influenza and its complications.”

Maternal influenza immunization rates have meanwhile stagnated, Dr. Wen added. Influenza “is something that we know is preventable, or at least mitigated, by a vaccine,” he said. “Our results serve as a reminder for clinicians to continue counseling on the importance of influenza vaccination among pregnant patients, and even in those who are planning to become pregnant.”

He said these findings suggest the need for a low threshold for treating pregnant patients who have influenza symptoms with over-the-counter therapies or closely monitoring them.

Adetola Louis-Jacques, MD, of the University of South Florida, Tampa, found the increase in morbidity in those with flu particularly unexpected and concerning.

“What surprised me was the big difference in how severe maternal morbidity rates increased over time in the influenza group compared to the group without influenza,” Dr. Louis-Jacques, who moderated the session, said in an interview. She agreed with Dr. Wen that the findings underscore the benefits of immunization.

“The study means we should reinforce to mothers how important the vaccine is. It’s critical,” Dr. Louis-Jacques said. “We should encourage mothers to get it and focus on educating women, trying to understand and allay [any concerns about the vaccine] and reinforce the importance of flu vaccination to decrease the likelihood of these mothers getting pretty sick during pregnancy.”

Racial/ethnic disparities in cesarean rates increase with greater maternal education

While the likelihood of a cesarean delivery usually drops as maternal education level increases, the disparities seen in cesarean rates between White and Black or Hispanic women actually increase with more maternal education, according to findings from a new study presented at the Pregnancy Meeting sponsored by the Society for Maternal-Fetal Medicine.

Typically, higher maternal education is associated with a lower likelihood of cesarean delivery, but this protective effect is much smaller for Black women and nonexistent for Hispanic women, leading to bigger gaps between these groups and White women, found Yael Eliner, MD, an ob.gyn. residency applicant at Boston University who conducted this research with her colleagues in the ob.gyn. department at Lenox Hill Hospital, New York, and Hofstra University, Hempstead, N.Y..

Researchers have previously identified racial and ethnic disparities in a wide range of maternal outcomes, including mortality, overall morbidity, preterm birth, low birth weight, fetal growth restriction, hypertensive disorders of pregnancy, diabetes, and cesarean deliveries. But the researchers wanted to know if the usual protective effects seen for cesarean deliveries existed in the racial and ethnic groups with these disparities. Past studies have already found that the protective effect of maternal education is greater for White women than Black women with infant mortality and overall self-rated health.

The researchers conducted a retrospective analysis of all low-risk nulliparous, term, singleton, vertex live births to U.S. residents from 2016 to 2019 by using the natality database of the Centers for Disease Control and Prevention. They looked only at women who were non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, and Hispanic women. They excluded women with pregestational and gestational diabetes, chronic hypertension, and hypertensive disorders of pregnancy.

Maternal education levels were stratified into those without a high school diploma, high school graduates (including those with some college credit), college graduates, and those with advanced degrees. The total population included 2,969,207 mothers with a 23.4% cesarean delivery rate.

Before considering education or other potential confounders, the cesarean delivery rate was 27.4% in Black women and 25.6% in Asian women, compared with 22.4% in White women and 23% in Hispanic women (P < .001).

Among those with less than a high school education, Black (20.9%), Asian (23.1%), and Hispanic (17.9% cesarean delivery prevalence was greater than that among White women (17.2%) (P < .001). The same was true among those with a high school education (with or without some college): 22% of White women in this group had cesarean deliveries compared with 26.3% of Black women, 26.3% of Asian women, and 22.5% of Hispanic women (P < .001).

At higher levels of education, the disparities not only persisted but actually increased.

The prevalence of cesarean deliveries was 23% in White college graduates, compared with 32.5% of Black college graduates, 26.3% of Asian college graduates, and 27.7% of Hispanic college graduates (P < .001). Similarly, in those with an advanced degree, the prevalence of cesarean deliveries in their population set was 23.6% of Whites, 36.3% of Blacks, 26.1% of Asians, and 30.1% of Hispanics (P < .001).

After adjusting for maternal education as well as age, prepregnancy body mass index, weight gain during pregnancy, insurance type, and neonatal birth weight, the researchers still found substantial disparities in cesarean delivery rates. Black women had 1.54 times greater odds of cesarean delivery than White women (P < .001). Similarly, the odds were 1.45 times greater for Asian women and 1.24 times greater for Hispanic women (P < .001).

Controlling for race, ethnicity, and the other confounders, women with less than a high school education or a high school diploma had similar likelihoods of cesarean delivery. The likelihood of a cesarean delivery was slightly reduced for women with a college degree (odds ratio, 0.93) or advanced degree (OR, 0.88). But this protective effect did not dampen racial/ethnic disparities. In fact, even greater disparities were seen at higher levels of education.

“At each level of education, all the racial/ethnic groups had significantly higher odds of a cesarean delivery than White women,” Dr. Eliner said. “Additionally, the racial/ethnic disparity in cesarean delivery rates increased with increasing level of education, and we specifically see a meaningful jump in the odds ratio at the college graduate level.”

She pointed out that the OR for cesarean delivery in Black women was 1.4 times greater than White women in the group with less than a high school education and 1.44 times greater in those with high school diplomas. Then it jumped to 1.69 in the college graduates group and 1.7 in the advanced degree group.

Higher maternal education was associated with a lower likelihood of cesarean delivery in White women and Asian women. White women with advanced degrees were 17% less likely to have a cesarean than White women with less than a high school education, and the respective reduction in risk was 19% for Asian women.

In Black women, however, education has a much smaller protective effect: An advanced degree reduced the odds of a cesarean delivery by only 7% and no significant difference showed up between high school graduates and college graduates, Dr. Eliner reported.

In Hispanic women, no protective effect showed up, and the odds of a cesarean delivery actually increased slightly in high school and college graduates above those with less than a high school education.

Dr. Eliner discussed a couple possible reasons for a less protective effect from maternal education in Black and Hispanic groups, including higher levels of chronic stress found in past research among racial/ethnic minorities with higher levels of education.

“The impact of racism as a chronic stressor and its association with adverse obstetric and prenatal outcomes is an emerging theme in health disparity research and is yet to be fully understood,” Dr. Eliner said in an interview. “Nonetheless, there is some evidence suggesting that racial/ethnic minorities with higher levels of education suffer from higher levels of stress.”

Implicit and explicit interpersonal bias and institutional racism may also play a role in the disparities, she said, and these factors may disproportionately affect the quality of care for more educated women. She also suggested that White women may be more comfortable advocating for their care.

“While less educated women from all racial/ethnic groups may lack the self-advocacy skills to discuss their labor course, educated White women may be more confident than women from educated minority groups,” Dr. Eliner told attendees. “They may therefore be better equipped to discuss the need for a cesarean delivery with their provider.”

Dr. Eliner elaborated on this: “Given the historical and current disparities of the health care system, women in racial/ethnic minorities may potentially be guarded in their interaction with medical professionals, with a reduced trust in the health care system, and may thus not feel empowered to advocate for themselves in this setting,” she said.

Dr. Allison Bryant Mantha

Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, suggested that bias and racism may play a role in this self-advocacy as well.

“I’m wondering if it might not be equally plausible that the advocacy might be met differently by who’s delivering the message,” Dr. Bryant Mantha said. “I think from the story of Dr. Susan Moore and patients who advocate for themselves, I think that we know there is probably some differential by who’s delivering the message.”

Finally, even though education is usually highly correlated with income and frequently used as a proxy for it, but the effect of education on income varies by race/ethnicity.

Since education alone is not sufficient to reduce these disparities, potential interventions should focus on increasing awareness of the disparities and the role of implicit bias, improving patients’ trust in the medical system, and training more doctors from underrepresented groups, Dr. Eliner said.

“I was also wondering about the overall patient choice,” said Sarahn M. Wheeler, MD, an assistant professor of ob.gyn. at Duke University Medical Center in Durham, N.C., who comoderated the session with Dr. Bryant Mantha. “Did we have any understanding of differences in patient values systems that might go into some of these differences in findings as well? There are lots of interesting concepts to explore and that this abstract brings up.”

Higher maternal education was associated with a lower likelihood of cesarean delivery in White women and Asian women. White women with advanced degrees were 17% less likely to have a cesarean than White women with less than a high school education, and the respective reduction in risk was 19% for Asian women.

In Black women, however, education has a much smaller protective effect: An advanced degree reduced the odds of a cesarean delivery by only 7% and no significant difference showed up between high school graduates and college graduates, Dr. Eliner reported.

In Hispanic women, no protective effect showed up, and the odds of a cesarean delivery actually increased slightly in high school and college graduates above those with less than a high school education.

Dr. Eliner discussed a couple possible reasons for a less protective effect from maternal education in Black and Hispanic groups, including higher levels of chronic stress found in past research among racial/ethnic minorities with higher levels of education.

“The impact of racism as a chronic stressor and its association with adverse obstetric and prenatal outcomes is an emerging theme in health disparity research and is yet to be fully understood,” Dr. Eliner said in an interview. “Nonetheless, there is some evidence suggesting that racial/ethnic minorities with higher levels of education suffer from higher levels of stress.”

Implicit and explicit interpersonal bias and institutional racism may also play a role in the disparities, she said, and these factors may disproportionately affect the quality of care for more educated women. She also suggested that White women may be more comfortable advocating for their care.

“While less educated women from all racial/ethnic groups may lack the self-advocacy skills to discuss their labor course, educated White women may be more confident than women from educated minority groups,” Dr. Eliner told attendees. “They may therefore be better equipped to discuss the need for a cesarean delivery with their provider.”

Dr. Eliner elaborated on this: “Given the historical and current disparities of the health care system, women in racial/ethnic minorities may potentially be guarded in their interaction with medical professionals, with a reduced trust in the health care system, and may thus not feel empowered to advocate for themselves in this setting,” she said.

Dr. Allison Bryant Mantha

Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, suggested that bias and racism may play a role in this self-advocacy as well.

“I’m wondering if it might not be equally plausible that the advocacy might be met differently by who’s delivering the message,” Dr. Bryant Mantha said. “I think from the story of Dr. Susan Moore and patients who advocate for themselves, I think that we know there is probably some differential by who’s delivering the message.”

Finally, even though education is usually highly correlated with income and frequently used as a proxy for it, but the effect of education on income varies by race/ethnicity.

Since education alone is not sufficient to reduce these disparities, potential interventions should focus on increasing awareness of the disparities and the role of implicit bias, improving patients’ trust in the medical system, and training more doctors from underrepresented groups, Dr. Eliner said.

“I was also wondering about the overall patient choice,” said Sarahn M. Wheeler, MD, an assistant professor of ob.gyn. at Duke University Medical Center in Durham, N.C., who comoderated the session with Dr. Bryant Mantha. “Did we have any understanding of differences in patient values systems that might go into some of these differences in findings as well? There are lots of interesting concepts to explore and that this abstract brings up.”

While the likelihood of a cesarean delivery usually drops as maternal education level increases, the disparities seen in cesarean rates between White and Black or Hispanic women actually increase with more maternal education, according to findings from a new study presented at the Pregnancy Meeting sponsored by the Society for Maternal-Fetal Medicine.

Typically, higher maternal education is associated with a lower likelihood of cesarean delivery, but this protective effect is much smaller for Black women and nonexistent for Hispanic women, leading to bigger gaps between these groups and White women, found Yael Eliner, MD, an ob.gyn. residency applicant at Boston University who conducted this research with her colleagues in the ob.gyn. department at Lenox Hill Hospital, New York, and Hofstra University, Hempstead, N.Y..

Researchers have previously identified racial and ethnic disparities in a wide range of maternal outcomes, including mortality, overall morbidity, preterm birth, low birth weight, fetal growth restriction, hypertensive disorders of pregnancy, diabetes, and cesarean deliveries. But the researchers wanted to know if the usual protective effects seen for cesarean deliveries existed in the racial and ethnic groups with these disparities. Past studies have already found that the protective effect of maternal education is greater for White women than Black women with infant mortality and overall self-rated health.

The researchers conducted a retrospective analysis of all low-risk nulliparous, term, singleton, vertex live births to U.S. residents from 2016 to 2019 by using the natality database of the Centers for Disease Control and Prevention. They looked only at women who were non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, and Hispanic women. They excluded women with pregestational and gestational diabetes, chronic hypertension, and hypertensive disorders of pregnancy.

Maternal education levels were stratified into those without a high school diploma, high school graduates (including those with some college credit), college graduates, and those with advanced degrees. The total population included 2,969,207 mothers with a 23.4% cesarean delivery rate.

Before considering education or other potential confounders, the cesarean delivery rate was 27.4% in Black women and 25.6% in Asian women, compared with 22.4% in White women and 23% in Hispanic women (P < .001).

Among those with less than a high school education, Black (20.9%), Asian (23.1%), and Hispanic (17.9% cesarean delivery prevalence was greater than that among White women (17.2%) (P < .001). The same was true among those with a high school education (with or without some college): 22% of White women in this group had cesarean deliveries compared with 26.3% of Black women, 26.3% of Asian women, and 22.5% of Hispanic women (P < .001).

At higher levels of education, the disparities not only persisted but actually increased.

The prevalence of cesarean deliveries was 23% in White college graduates, compared with 32.5% of Black college graduates, 26.3% of Asian college graduates, and 27.7% of Hispanic college graduates (P < .001). Similarly, in those with an advanced degree, the prevalence of cesarean deliveries in their population set was 23.6% of Whites, 36.3% of Blacks, 26.1% of Asians, and 30.1% of Hispanics (P < .001).

After adjusting for maternal education as well as age, prepregnancy body mass index, weight gain during pregnancy, insurance type, and neonatal birth weight, the researchers still found substantial disparities in cesarean delivery rates. Black women had 1.54 times greater odds of cesarean delivery than White women (P < .001). Similarly, the odds were 1.45 times greater for Asian women and 1.24 times greater for Hispanic women (P < .001).

Controlling for race, ethnicity, and the other confounders, women with less than a high school education or a high school diploma had similar likelihoods of cesarean delivery. The likelihood of a cesarean delivery was slightly reduced for women with a college degree (odds ratio, 0.93) or advanced degree (OR, 0.88). But this protective effect did not dampen racial/ethnic disparities. In fact, even greater disparities were seen at higher levels of education.

“At each level of education, all the racial/ethnic groups had significantly higher odds of a cesarean delivery than White women,” Dr. Eliner said. “Additionally, the racial/ethnic disparity in cesarean delivery rates increased with increasing level of education, and we specifically see a meaningful jump in the odds ratio at the college graduate level.”

She pointed out that the OR for cesarean delivery in Black women was 1.4 times greater than White women in the group with less than a high school education and 1.44 times greater in those with high school diplomas. Then it jumped to 1.69 in the college graduates group and 1.7 in the advanced degree group.

Higher maternal education was associated with a lower likelihood of cesarean delivery in White women and Asian women. White women with advanced degrees were 17% less likely to have a cesarean than White women with less than a high school education, and the respective reduction in risk was 19% for Asian women.

In Black women, however, education has a much smaller protective effect: An advanced degree reduced the odds of a cesarean delivery by only 7% and no significant difference showed up between high school graduates and college graduates, Dr. Eliner reported.

Neighborhood police complaints tied to Black preterm birth rates

Article Type

The more complaints of excessive force by police reported by neighborhood residents, the more likely it is that Black pregnant people living in that neighborhood will deliver preterm, according to findings from a new study presented Jan. 28 at the virtual Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.

Dr. Alexa Freedman

“We know there are significant racial disparities in preterm birth which aren’t fully explained by traditional risk factors, like being older, having health problems like high blood pressure, or limited income,” Alexa Freedman, PhD, a postdoctoral fellow at NorthShore University HealthSystem and Northwestern University Institute for Policy Research, Evanston, Ill., told this news organization. “This has left many wondering if there are stressors unique to Black individuals that may be involved,” which has led to past research on the association of preterm birth with neighborhood segregation and historical “redlining” practices.

Black individuals have a substantially higher rate of preterm birth, compared with all other racial and ethnic groups in the US: 13.8% of Black infants born between 2016 and 2018 were preterm, compared with 11.6% among Native Americans – the next highest group – and 9.1% among White women.

“Studies have shown that psychosocial stress contributes to preterm birth disparities, potentially through several physiologic pathways that impact pregnancy outcomes,” Dr. Freedman told attendees. “Pregnant Black individuals have been reported to experience greater psychosocial stress regardless of socioeconomic status, possibly secondary to experiences of racism and discrimination.”

Though past research has examined neighborhood disadvantage and violence as stressors potentially contributing to preterm birth, little data exist on police–community relationships or police violence and pregnancy outcomes, despite being a “particularly salient stressor for Black individuals,” Dr. Freedman said. “Among pregnant Black individuals, prenatal depression has been correlated with concern about negative interactions between youth in their community and police.” To cite one example of the prevalence of racial bias in policing, she noted that “Chicago police are almost 10 times more likely to use force when interacting with a Black individual as compared [with] a White individual.”

The researchers therefore sought to determine whether a relationship existed between preterm birth rates and complaints regarding use of excessive force by police in the same neighborhood. They compiled records on all singleton live births from one Chicago hospital between March 2008 and March 2018, excluding those who lived outside Chicago, had a missing address, listed their race as “other,” or lacked data for specific other confounders.
 

Assessing police complaints within census blocks

The researchers obtained data on police complaints in Chicago from the Invisible Institute’s Citizen Police Data Project. They focused only on complaints of excessive use of force, “such as unnecessary physical contact and unnecessary display of a weapon,” Dr. Freedman said. They considered a person exposed in the neighborhood if a complaint was reported in her census block in the year leading up to birth. During their study period, more than 6,000 complaints of excessive force were reported across an estimated 70% of the blocks.

The study population had an average age of 31 and included 59.5% White, 12% Black, 20% Hispanic, and 8.5% Asian people. Just over half the pregnancies (55%) were first-time pregnancies, and 3.3% of the population had a history of preterm birth (before 37 weeks). The researchers also gathered data to adjust for the study population’s:

  • Age
  • Parity (number of times the woman has given birth).
  • Population size of census block.
  • Exposure to a homicide on the block in the year leading up to birth.
  • Socioeconomic status by block (based on a composite of median home value, median income, percentage of a high school diploma, and percentage employed).

“Those who lived in a block with an excessive force complaint were more likely to be Black, more likely to deliver preterm, and more likely to be exposed to homicide,” Dr. Freedman told attendees.

The proportion of pregnant women exposed to police complaints was 15.8%, and 10.2% lived in neighborhoods where a homicide occurred in the year leading up to birth. Within the group exposed to a homicide, 16.5% lived in a neighborhood with an excessive force complaint and 9.1% did not.

Overall, 8.1% of the population gave birth preterm. When stratified by whether or not they lived in a block with an excessive force complaint, the researchers found the proportion of preterm births was higher among those who did than those who did not (9.3% vs. 7.8%).

Both before and after adjusting for confounders, Black people were the only racial/ethnic group who had a significantly increased risk of preterm birth if they lived on a block with a complaint. They were nearly 30% more likely to deliver preterm if an excessive force complaint had been reported nearby (odds ratio, 1.29). The odds of preterm birth were slightly elevated for White people and slightly reduced for Hispanic and Asian people, but none of those associations reached significance.

In a sensitivity analysis comparing 189 Black individuals to themselves, the researchers compared those who had one preterm birth and one term birth. They found that the preterm birth was 32% more likely to occur in a year when an excessive force complaint was filed after adjusting for age and birth order (OR, 1.32; 95% confidence interval, 0.82-2.13).

“Police violence reflects just one component of structural racism,” Dr. Freedman said in an interview. “Our findings highlight the need to more thoroughly consider how these systemic and structural factors contribute to disparities in maternal and fetal health.”
 

Clinical and policy implications

The clinical implications of these findings focus on the need for obstetric clinical teams to understand patients’ stressors and to provide support and resources, according to Dr. Freedman’s mentor, Ann Borders, MD, MSc, MPH, a maternal-fetal medicine physician at NorthShore and Evanston Hospital and a clinical associate professor at the University of Chicago Pritzker School of Medicine.

“Potential strategies include training on improved listening and respectful patient-centered care, such as provided by the CDC Hear Her campaign, and consideration of universal social determinants of health screening during obstetric care,” Dr. Borders told this news organization..

Though the study included a large sample size and allowed the researchers to control for individual and neighborhood characteristics, Dr. Freedman acknowledged that census blocks may or may not correlate with the way individuals define their own neighborhoods. They also didn’t have the data to assess the quality of prenatal care or the type of preterm birth, but they are developing a qualitative study to determine the best ways of measuring exposure to police violence.

In addition, the researchers’ reliance only on formal police complaints could have underestimated prevalence of excessive force, and the study did not take into account people’s direct experience with police violence; police violence that occurs within a person’s social network; or police violence widely covered in the news. 

It wasn’t possible for the researchers to verify whether excessive force actually occurred or whether the force might have been justified, and it instead relied on the fact that someone lodged a complaint because he or she perceived the action as excessive.

Allison Bryant Mantha, MD, MPH, vice chair for Quality, Equity, and Safety at Massachusetts General Hospital in Boston and a board member of SMFM, said she was impressed with the adjustment of homicide exposure as a proxy for neighborhood crime.

“Many might assume that reports of police misconduct might be a marker for a ‘dangerous neighborhood,’ and it was thoughtful of the authors to adjust their analyses for exposure to crime to demonstrate that, even above and beyond crime, reports of police misconduct seem to be associated with adverse outcomes,” Dr. Bryant Mantha, who moderated the session, said in an interview.

Confronting this issue goes beyond what clinicians can do on their own, Dr. Bryant Mantha suggested.

“The greatest change will come with addressing the structural racism that underlies differential exposure to police misconduct in communities in the first place,” she said. “Concurrent with this, however, clinicians may consider adding in an assessment of neighborhood characteristics to include reports of police misconduct as they screen for other social determinants of health. While we do not have intervention studies to demonstrate efficacy, it is not a huge leap to imagine that recognition of this burden in individuals’ lives, plus offering ways to manage stress or seek redress, could be of benefit.”

The research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the Northwestern Medicine Enterprise Data Warehouse Pilot Data Program. Dr. Freedman, Dr. Borders, and Dr. Bryant Mantha have disclosed no relevant financial relationships.

The clinical implications of these findings focus on the need for obstetric clinical teams to understand patients’ stressors and to provide support and resources, according to Dr. Freedman’s mentor, Ann Borders, MD, MSc, MPH, a maternal-fetal medicine physician at NorthShore and Evanston Hospital and a clinical associate professor at the University of Chicago Pritzker School of Medicine.

“Potential strategies include training on improved listening and respectful patient-centered care, such as provided by the CDC Hear Her campaign, and consideration of universal social determinants of health screening during obstetric care,” Dr. Borders told this news organization..

Though the study included a large sample size and allowed the researchers to control for individual and neighborhood characteristics, Dr. Freedman acknowledged that census blocks may or may not correlate with the way individuals define their own neighborhoods. They also didn’t have the data to assess the quality of prenatal care or the type of preterm birth, but they are developing a qualitative study to determine the best ways of measuring exposure to police violence.

In addition, the researchers’ reliance only on formal police complaints could have underestimated prevalence of excessive force, and the study did not take into account people’s direct experience with police violence; police violence that occurs within a person’s social network; or police violence widely covered in the news. 

It wasn’t possible for the researchers to verify whether excessive force actually occurred or whether the force might have been justified, and it instead relied on the fact that someone lodged a complaint because he or she perceived the action as excessive.

Allison Bryant Mantha, MD, MPH, vice chair for Quality, Equity, and Safety at Massachusetts General Hospital in Boston and a board member of SMFM, said she was impressed with the adjustment of homicide exposure as a proxy for neighborhood crime.

“Many might assume that reports of police misconduct might be a marker for a ‘dangerous neighborhood,’ and it was thoughtful of the authors to adjust their analyses for exposure to crime to demonstrate that, even above and beyond crime, reports of police misconduct seem to be associated with adverse outcomes,” Dr. Bryant Mantha, who moderated the session, said in an interview.

Confronting this issue goes beyond what clinicians can do on their own, Dr. Bryant Mantha suggested.

“The greatest change will come with addressing the structural racism that underlies differential exposure to police misconduct in communities in the first place,” she said. “Concurrent with this, however, clinicians may consider adding in an assessment of neighborhood characteristics to include reports of police misconduct as they screen for other social determinants of health. While we do not have intervention studies to demonstrate efficacy, it is not a huge leap to imagine that recognition of this burden in individuals’ lives, plus offering ways to manage stress or seek redress, could be of benefit.”

The research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the Northwestern Medicine Enterprise Data Warehouse Pilot Data Program. Dr. Freedman, Dr. Borders, and Dr. Bryant Mantha have disclosed no relevant financial relationships.

Racial disparities in maternal morbidity persist even with equal access to care

An analysis of data from the U.S. military suggests that the maternal morbidity disparities between Black and White women cannot be attributed solely to differences in access to care and socioeconomics.

Dr. Jameaka Hamilton

Even in the U.S. military health care system, where all service members have universal access to the same facilities and providers, researchers found substantial racial disparities in cesarean deliveries, maternal ICU admission, and overall severe maternal morbidity and mortality between Black patients and White patients, according to findings from a new study presented Jan. 28, 2021, at a meeting sponsored by the Society for Maternal-Fetal Medicine.

“This was surprising given some of the driving theories behind maternal race disparities encountered in this country, such as access to care and socioeconomic status, are controlled for in this health care system,” Capt. Jameaka Hamilton, MD, who presented the research, said in an interview. “Our findings indicate that there are likely additional factors at play which impact the obstetrical outcomes of women based upon their race, including systems-based barriers to accessing the military health care system which contribute to health care disparities, or in systemic or implicit biases which occur within our health care delivery.”

Plenty of recent research has documented the rise in maternal morbidity and mortality in the United States and the considerable racial disparities within those statistics. Black women are twice as likely to suffer morbidity and three to four times more likely to die in childbirth, compared with White women, Dr. Hamilton, an ob.gyn. from the San Antonio Uniformed Services Health Education Consortium at Ft. Sam Houston in San Antonio, Texas, reminded attendees. So far, much of this disparity has been attributed to social determinants of health.

Military retirees, active-duty personnel, and dependents, however, have equal access to federal health insurance and care at military health care facilities, or at covered civilian facilities where needed. Hence the researchers’ hypothesis that the military medical system would not show the same disparities by race that are seen in civilian populations.

The researchers analyzed maternal morbidity data from the Neonatal Perinatal Information Center from April 2018 to March 2019. The retrospective study included data from 13 military treatment facilities that had more than 1,000 deliveries per year. In addition to statistics on cesarean delivery and adult ICU admission, the researchers compared numbers on overall severe maternal morbidity based on the indicators defined by the Centers for Disease Control and Prevention.

The 15,305 deliveries included 23% Black patients and 77% White patients from the Air Force, Army, and Navy branches.

The cesarean delivery rate ranged from 19.4% to 35.5%. ICU admissions totaled 38 women, 190 women had postpartum hemorrhage, and 282 women experienced severe maternal morbidity. All three measures revealed racial disparities:

  • Overall severe maternal morbidity occurred in 2.66% of Black women and 1.66% of White women (P =.0001).
  • ICU admission occurred in 0.49% of Black women and 0.18% of White women (P =.0026).
  • 31.68% of Black women had a cesarean delivery, compared with 23.58% of White women (P <.0001).
 

 

After excluding cases with blood transfusions, Black women were twice as likely to have severe maternal morbidity (0.64% vs. 0.32%). There were no significant differences in postpartum hemorrhage rates between Black and White women, but this analysis was limited by the small overall numbers of postpartum hemorrhage.

Among the study’s limitations were the inability to stratify patients by retiree, active duty, or dependent status, and the lack of data on preeclampsia rates, maternal age, obesity, or other preexisting conditions. In addition, the initial dataset included 61% of patients who reported their race as “other” than Black or White, limiting the number of patients whose data could be analyzed. Since low-volume hospitals were excluded, the outcomes could be skewed if lower-volume facilities are more likely to care for more complex cases, Dr. Hamilton added.

Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, praised Dr. Hamilton’s work for revealing that differential access – though still problematic – cannot fully explain inequities between Black women and other women.

“The findings are not shocking given that what underlies some of these inequities – namely structural and institutional racism, and differential treatment within the system – are not exclusive to civilian health care settings,” Dr. Bryant Mantha, who moderated the session, said in an interview. “That said, doing the work to demonstrate this is extremely valuable.”

Although the causes of these disparities are systemic, Dr. Hamilton said individual providers can play a role in addressing them.

“There can certainly be more done to address this dangerous trend at the provider, hospital/institution, and national level,” she said. I think we as providers should continue to self-reflect and address our own biases. Hospitals and institutions should continue to develop policies that draw attention health care disparities.”

Completely removing these inequalities, however, will require confronting the racism embedded in U.S. health care at all levels, Dr. Bryant Mantha suggested.

“Ultimately, moving to an antiracist health care system – and criminal justice system, educational system, political system, etc. – and dismantling the existing structural racism in policies and practices will be needed to drive this change,” Dr. Bryant Mantha said. “Individual clinicians can use their voices to advocate for these changes in their health systems, communities, and states. Awareness of these inequities is critical, as is a sense of collective efficacy that we can, indeed, change the status quo.”

Dr. Hamilton and Dr. Bryant Mantha reported no disclosures.

Low-dose aspirin did not reduce preterm birth rates but don’t rule it out yet

Article Type

Wed, 02/10/2021 - 12:35

Women at risk of preterm birth who took daily low-dose aspirin did not have significantly lower rates of preterm birth than those who did not take aspirin, according to preliminary findings from a small randomized controlled trial. There was a trend toward lower rates, especially among those with the highest compliance, but the study was underpowered to detect a difference with statistical significance, said Anadeijda Landman, MD, of the Amsterdam University Medical Center. Dr. Landman presented the findings Jan. 28 at a meeting sponsored by the Society for Maternal-Fetal Medicine.

Dr. Anadeijda Landman

Preterm birth accounts for a third of all neonatal mortality, she told attendees. Among 15 million preterm births worldwide each year, 65% are spontaneous, indicating the need for effective preventive interventions. Dr. Landman reviewed several mechanisms by which aspirin may help reduce preterm birth via different pathways.

The researchers’ multicenter, placebo-controlled trial involved 8 tertiary care and 26 secondary care hospitals in the Netherlands between May 2016 and June 2019. Starting between 8 and 15 weeks’ gestation, women took either 80 mg of aspirin or a placebo daily until 36 weeks’ gestation or delivery. Women also received progesterone, cerclage, or pessary as indicated according to local protocols.

The study enrolled 406 women with singleton pregnancy and a history of preterm birth delivered between 22 and 37 weeks’ gestation. The final analysis, after exclusions for pregnancy termination, congenital anomalies, multiples pregnancy, or similar reasons, included 193 women in the intervention group and 194 in the placebo group. The women had similar baseline characteristics across both groups except a higher number of past mid-trimester fetal deaths in the aspirin group.

“It’s important to realize these women had multiple preterm births, as one of our inclusion criteria was previous spontaneous preterm birth later than 22 weeks’ gestation, so this particular group is very high risk for cervical insufficiency as a probable cause,” Dr. Landman told attendees.

Among women in the aspirin group, 21.2% delivered before 37 weeks, compared with 25.4% in the placebo group (P = .323). The rate of spontaneous birth was 20.1% in the aspirin group and 23.8% in the placebo group (P = .376). Though still not statistically significant, the difference between the groups was larger when the researchers limited their analysis to the 245 women with at least 80% compliance: 18.5% of women in the aspirin group had a preterm birth, compared with 24.8% of women in the placebo group (P = .238).

There were no significant differences between the groups in composite poor neonatal outcomes or in a range of prespecified newborn complications. The aspirin group did have two stillbirths, two mid-trimester fetal losses, and two extremely preterm newborns (at 24+2 weeks and 25+2 weeks). The placebo group had two mid-trimester fetal losses.

“These deaths are inherent to the study population, and it seems unlikely they are related to the use of aspirin,” Dr. Landman said. “Moreover other aspirin studies have not found an increased perinatal mortality rate, and some large studies indicated the neonatal mortality rate is even reduced.”

Although preterm birth only trended lower in the aspirin group, Dr. Landman said the researchers believe they cannot rule out an effect from aspirin.

“It’s also important to note that our study was underpowered as the recurrence risk of preterm birth in our study was lower than expected, so it’s possible a small treatment effect of aspirin could not be demonstrated in our study,” she said. “And, despite the proper randomization procedure, many more women in the aspirin group had a previous mid-trimester fetal loss. This indicates that the aspirin group might be more at risk for preterm birth than the placebo group, and this imbalance could also have diminished a small protective effect of aspirin.”

In response to an audience question, Dr. Landman acknowledged that more recent studies on aspirin have used 100- to 150-mg dosages, but that evidence was not as clear when their study began in 2015. She added that her research team does not advise changing clinical care currently and believes it is too soon to recommend aspirin to this population.

Dr. Tracy Manuck

Tracy Manuck, MD, MS, an associate professor of ob.gyn. at the University of North Carolina in Chapel Hill, agreed that it is premature to begin prescribing aspirin for preterm birth prevention, but she noted that most of the patients she cares for clinically already meet criteria for aspirin based on their risk factors for preeclampsia.

“Additional research is needed in the form of a well-designed and large [randomized, controlled trial],” Dr Manuck, who moderated the session, said in an interview. “However, such a trial is becoming increasingly difficult to conduct because so many pregnant women qualify to receive aspirin for the prevention of preeclampsia due to their weight, medical comorbidities, or prior pregnancy history.”

She said she anticipates seeing patient-level data meta-analyses in the coming months as more data on aspirin for preterm birth prevention are published.

“Given that these data are supportive of the overall trends seen in prior publications, I do think that low-dose aspirin will eventually bear out as a helpful preventative measure to prevent recurrent preterm birth. Aspirin is low risk, readily available, and is inexpensive,” Dr. Manuck said. “I hope that meta-analysis data will provide additional information regarding the benefit of low-dose aspirin for prematurity prevention.”

The research was funded by the Dutch Organization for Health Care Research and the Dutch Consortium for Research in Women’s Health. Dr. Landman and Dr. Manuck had no disclosures.

The aspirin group did have two stillbirths, two mid-trimester fetal losses, and two extremely preterm newborns (at 24+2 weeks and 25+2 weeks). The placebo group had two mid-trimester fetal losses.

“These deaths are inherent to the study population, and it seems unlikely they are related to the use of aspirin,” Dr. Landman said. “Moreover other aspirin studies have not found an increased perinatal mortality rate, and some large studies indicated the neonatal mortality rate is even reduced.”

Although preterm birth only trended lower in the aspirin group, Dr. Landman said the researchers believe they cannot rule out an effect from aspirin.

“It’s also important to note that our study was underpowered as the recurrence risk of preterm birth in our study was lower than expected, so it’s possible a small treatment effect of aspirin could not be demonstrated in our study,” she said. “And, despite the proper randomization procedure, many more women in the aspirin group had a previous mid-trimester fetal loss. This indicates that the aspirin group might be more at risk for preterm birth than the placebo group, and this imbalance could also have diminished a small protective effect of aspirin.”

In response to an audience question, Dr. Landman acknowledged that more recent studies on aspirin have used 100- to 150-mg dosages, but that evidence was not as clear when their study began in 2015. She added that her research team does not advise changing clinical care currently and believes it is too soon to recommend aspirin to this population.

Dr. Tracy Manuck

Tracy Manuck, MD, MS, an associate professor of ob.gyn. at the University of North Carolina in Chapel Hill, agreed that it is premature to begin prescribing aspirin for preterm birth prevention, but she noted that most of the patients she cares for clinically already meet criteria for aspirin based on their risk factors for preeclampsia.

“Additional research is needed in the form of a well-designed and large [randomized, controlled trial],” Dr Manuck, who moderated the session, said in an interview. “However, such a trial is becoming increasingly difficult to conduct because so many pregnant women qualify to receive aspirin for the prevention of preeclampsia due to their weight, medical comorbidities, or prior pregnancy history.”

She said she anticipates seeing patient-level data meta-analyses in the coming months as more data on aspirin for preterm birth prevention are published.

“Given that these data are supportive of the overall trends seen in prior publications, I do think that low-dose aspirin will eventually bear out as a helpful preventative measure to prevent recurrent preterm birth. Aspirin is low risk, readily available, and is inexpensive,” Dr. Manuck said. “I hope that meta-analysis data will provide additional information regarding the benefit of low-dose aspirin for prematurity prevention.”

The research was funded by the Dutch Organization for Health Care Research and the Dutch Consortium for Research in Women’s Health. Dr. Landman and Dr. Manuck had no disclosures.

COVID-19 in pregnancy tied to hypertension, preeclampsia

Article Type
Changed
Thu, 08/26/2021 - 15:51

Having COVID-19 during pregnancy is linked to a significantly increased risk for gestational hypertension and preeclampsia compared with not having COVID-19 while pregnant, according to findings from a retrospective study presented Jan. 28 at the Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.

“This was not entirely surprising given that inflammation has been implicated in the pathogenesis of both hypertensive disorders of pregnancy and COVID-19 infection and thus may serve to exacerbate each other,” Nigel Madden, MD, a resident physician in the ob.gyn. department at Columbia University, New York. , told this news organization after she presented the results.

Hypertensive disorders of pregnancy occur in 10%-15% of all pregnancies and are the leading cause of maternal and perinatal morbidity and mortality worldwide, Dr. Madden told attendees of the meeting. Although it’s not clear what causes hypertensive diseases in pregnancy generally, “it is possible that the acute inflammatory state of the COVID infection may incite or exacerbate hypertensive disease of pregnancy,” Dr. Madden said.

The researchers conducted a retrospective chart review of 1,715 patients who had a singleton pregnancy and who underwent routine nasal polymerase chain reaction testing at admission to one institution’s labor and delivery department between March and June 2020. The researchers excluded patients who had a history of chronic hypertension.

Overall, 10% of the patients tested positive for COVID-19 (n = 167), and 90% tested negative (n = 1,548). There were several differences at baseline between the groups. Those who tested positive tended to be younger, with an average age of 28, compared with an average age of 31 years for the group that tested negative. The group that tested negative also had a higher proportion of mothers aged 35 and older (P < .01). There were also significant differences in the racial makeup of the groups. Half of those in the COVID-positive group reported “other” for their race. The biggest baseline disparity between the groups was with regard to insurance type: 73% of those who tested positive for COVID-19 used Medicaid; only 36% of patients in the COVID-negative group used Medicaid. Those with private insurance were more likely to test negative (43%) than positive (25%) (P < .01).

The researchers defined gestational hypertension as having a systolic blood pressure greater than or equal to 140 mm Hg or a diastolic blood pressure greater than or equal to 90 mm Hg on two occasions at least 4 hours apart. A preeclampsia diagnosis required elevated blood pressure (using the same definition as for hypertension) as well as proteinuria, characterized by a protein/creatine ratio greater than or equal to 0.3 mg/dL or greater than or equal to 300 mg of protein on a 24-hour urine collection. Preeclampsia with severe features required prespecified laboratory abnormalities, pulmonary edema, or symptoms of headache, vision changes, chest pain, shortness of breath, or right upper quadrant pain.

More than twice as many patients with COVID had a hypertensive disorder of pregnancy (18%) as those who tested negative (8%). The patients who were COVID positive were significantly more likely than those who tested negative to have gestational hypertension and preeclampsia without severe features. Rates of preeclampsia with severe features were not significantly different between the groups.

The severity of hypertensive disease did not differ between the groups. Limitations of the study included its retrospective design, the small number of COVID-positive patients, and the fact that it was conducted at a single institution in New York. However, the study population was diverse, and it was conducted during the height of infections at the epicenter of the COVID-19 pandemic.

“This was a study of great clinical significance,” said Kim Boggess, MD, of the University of North Carolina at Chapel Hill, while moderating the session. “I would argue that you guys in New York are the best poised to answer some of the questions that need to be answered as it relates to the effect of coronavirus infection in pregnancy.”

Dr. Boggess asked whether the study examined associations related to the severity of COVID-19. Only 10 of the patients were symptomatic, Dr. Madden said, and only one of those patients developed preeclampsia with severe features.

Michelle Y. Owens, MD, professor and chief of maternal fetal medicine at the University of Mississippi Medical Center, Jackson, who also moderated the session, said in an interview that the findings call for physicians to remain vigilant about evaluating patients who test positive for COVID-19 for hypertensive disease and disorders.

“Additionally, these women should be educated about hypertensive disorders and the common symptoms to facilitate early diagnosis and treatment when indicated,” Dr. Owens said. “I believe this is of particular interest in those women who are not severely affected by COVID, as these changes may occur while they are undergoing quarantine or being monitored remotely. This amplifies the need for remote assessment or home monitoring of maternal blood pressures.”

Dr. Madden, Dr. Boggess, and Dr. Owens have disclosed no relevant financial relationships.

Maternal COVID antibodies cross placenta, detected in newborns

Article Type
Changed
Thu, 08/26/2021 - 15:51

Antibodies against SARS-CoV-2 cross the placenta during pregnancy and are detectable in most newborns born to mothers who had COVID-19 during pregnancy, according to findings from a study presented Jan. 28 at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“I think the most striking finding is that we noticed a high degree of neutralizing response to natural infection even among asymptomatic infection, but of course a higher degree was seen in those with symptomatic infection,” Naima Joseph, MD, MPH, of Emory University, Atlanta, said in an interview.

“Our data demonstrate maternal capacity to mount an appropriate and robust immune response,” and maternal protective immunity lasted at least 28 days after infection, Dr. Joseph said. “Also, we noted higher neonatal cord blood titers in moms with higher titers, which suggests a relationship, but we need to better understand how transplacental transfer occurs as well as establish neonatal correlates of protection in order to see if and how maternal immunity may also benefit neonates.”

The researchers analyzed the amount of IgG and IgM antibodies in maternal and cord blood samples prospectively collected at delivery from women who tested positive for COVID-19 at any time while pregnant. They used enzyme-linked immunosorbent assay to assess for antibodies for the receptor binding domain of the SARS-CoV-2 spike protein.

The 32 pairs of mothers and infants in the study were predominantly non-Hispanic Black (72%) and Hispanic (25%), and 84% used Medicaid as their payer. Most of the mothers (72%) had at least one comorbidity, most commonly obesityhypertension, and asthma or pulmonary disease. Just over half the women (53%) were symptomatic while they were infected, and 88% were ill with COVID-19 during the third trimester. The average time from infection to delivery was 28 days.

All the mothers had IgG antibodies, 94% had IgM antibodies, and 94% had neutralizing antibodies against SARS-CoV-2. Among the cord blood samples, 91% had IgG antibodies, 9% had IgM antibodies, and 25% had neutralizing antibodies.

“It’s reassuring that, so far, the physiological response is exactly what we expected it to be,” Judette Louis, MD, MPH, an associate professor of ob.gyn. and the ob.gyn. department chair at the University of South Florida, Tampa, said in an interview. “It’s what we would expect, but it’s always helpful to have more data to support that. Otherwise, you’re extrapolating from what you know from other conditions,” said Dr. Louis, who moderated the oral abstracts session.

Symptomatic infection was associated with significantly higher IgG titers than asymptomatic infection (P = .03), but no correlation was seen for IgM or neutralizing antibodies. In addition, although mothers who delivered more than 28 days after their infection had higher IgG titers (P = .05), no differences existed in IgM or neutralizing response.

Infants’ cord blood titers were significantly lower than their corresponding maternal samples, independently of symptoms or latency from infection to delivery (P < .001), Dr. Joseph reported.

“Transplacental efficiency in other pathogens has been shown to be correlated with neonatal immunity when the ratio of cord to maternal blood is greater than 1,” Dr. Joseph said in her presentation. Their data showed “suboptimal efficiency” at a ratio of 0.81.

The study’s small sample size and lack of a control group were weaknesses, but a major strength was having a population at disproportionately higher risk for infection and severe morbidity than the general population.
 

 

 

Implications for maternal COVID-19 vaccination

Although the data are not yet available, Dr. Joseph said they have expanded their protocol to include vaccinated pregnant women.

“The key to developing an effective vaccine [for pregnant people] is in really characterizing adaptive immunity in pregnancy,” Dr. Joseph told SMFM attendees. “I think that these findings inform further vaccine development in demonstrating that maternal immunity is robust.”

The World Health Organization recently recommended withholding COVID-19 vaccines from pregnant people, but the SMFM and American College of Obstetricians and Gynecologists subsequently issued a joint statement reaffirming that the COVID-19 vaccines authorized by the FDA “should not be withheld from pregnant individuals who choose to receive the vaccine.”

“One of the questions people ask is whether in pregnancy you’re going to mount a good response to the vaccine the way you would outside of pregnancy,” Dr. Louis said. “If we can demonstrate that you do, that may provide the information that some mothers need to make their decisions.” Data such as those from Dr. Joseph’s study can also inform recommendations on timing of maternal vaccination.

“For instance, Dr. Joseph demonstrated that, 28 days out from the infection, you had more antibodies, so there may be a scenario where we say this vaccine may be more beneficial in the middle of the pregnancy for the purpose of forming those antibodies,” Dr. Louis said.
 

Consensus emerging from maternal antibodies data

The findings from Dr. Joseph’s study mirror those reported in a study published online Jan. 29 in JAMA Pediatrics. That study, led by Dustin D. Flannery, DO, MSCE, of Children’s Hospital of Philadelphia, also examined maternal and neonatal levels of IgG and IgM antibodies against the receptor binding domain of the SARS-CoV-2 spike protein. They also found a positive correlation between cord blood and maternal IgG concentrations (P < .001), but notably, the ratio of cord to maternal blood titers was greater than 1, unlike in Dr. Joseph’s study.

For their study, Dr. Flannery and colleagues obtained maternal and cord blood sera at the time of delivery from 1471 pairs of mothers and infants, independently of COVID status during pregnancy. The average maternal age was 32 years, and just over a quarter of the population (26%) were Black, non-Hispanic women. About half (51%) were White, 12% were Hispanic, and 7% were Asian.

About 6% of the women had either IgG or IgM antibodies at delivery, and 87% of infants born to those mothers had measurable IgG in their cord blood. No infants had IgM antibodies. As with the study presented at SMFM, the mothers’ infections included asymptomatic, mild, moderate, and severe cases, and the degree of severity of cases had no apparent effect on infant antibody concentrations. Most of the women who tested positive for COVID-19 (60%) were asymptomatic.

Among the 11 mothers who had antibodies but whose infants’ cord blood did not, 5 had only IgM antibodies, and 6 had significantly lower IgG concentrations than those seen in the other mothers.

In a commentary about the JAMA Pediatrics study, Flor Munoz, MD, of the Baylor College of Medicine, Houston, suggested that the findings are grounds for optimism about a maternal vaccination strategy to protect infants from COVID-19.

“However, the timing of maternal vaccination to protect the infant, as opposed to the mother alone, would necessitate an adequate interval from vaccination to delivery (of at least 4 weeks), while vaccination early in gestation and even late in the third trimester could still be protective for the mother,” Dr. Munoz wrote.

Given the interval between two-dose vaccination regimens and the fact that transplacental transfer begins at about the 17th week of gestation, “maternal vaccination starting in the early second trimester of gestation might be optimal to achieve the highest levels of antibodies in the newborn,” Dr. Munoz wrote. But questions remain, such as how effective the neonatal antibodies would be in protecting against COVID-19 and how long they last after birth.

No external funding was used in Dr. Joseph’s study. Dr. Joseph and Dr. Louis have disclosed no relevant financial relationships. The JAMA Pediatrics study was funded by the Children’s Hospital of Philadelphia. One coauthor received consultancy fees from Sanofi Pasteur, Lumen, Novavax, and Merck unrelated to the study. Dr. Munoz served on the data and safety monitoring boards of Moderna, Pfizer, Virometix, and Meissa Vaccines and has received grants from Novavax Research and Gilead Research.

Antibodies against SARS-CoV-2 cross the placenta during pregnancy and are detectable in most newborns born to mothers who had COVID-19 during pregnancy, according to findings from a study presented Jan. 28 at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“I think the most striking finding is that we noticed a high degree of neutralizing response to natural infection even among asymptomatic infection, but of course a higher degree was seen in those with symptomatic infection,” Naima Joseph, MD, MPH, of Emory University, Atlanta, said in an interview.

“Our data demonstrate maternal capacity to mount an appropriate and robust immune response,” and maternal protective immunity lasted at least 28 days after infection, Dr. Joseph said. “Also, we noted higher neonatal cord blood titers in moms with higher titers, which suggests a relationship, but we need to better understand how transplacental transfer occurs as well as establish neonatal correlates of protection in order to see if and how maternal immunity may also benefit neonates.”

The researchers analyzed the amount of IgG and IgM antibodies in maternal and cord blood samples prospectively collected at delivery from women who tested positive for COVID-19 at any time while pregnant. They used enzyme-linked immunosorbent assay to assess for antibodies for the receptor binding domain of the SARS-CoV-2 spike protein.

The 32 pairs of mothers and infants in the study were predominantly non-Hispanic Black (72%) and Hispanic (25%), and 84% used Medicaid as their payer. Most of the mothers (72%) had at least one comorbidity, most commonly obesityhypertension, and asthma or pulmonary disease. Just over half the women (53%) were symptomatic while they were infected, and 88% were ill with COVID-19 during the third trimester. The average time from infection to delivery was 28 days.

All the mothers had IgG antibodies, 94% had IgM antibodies, and 94% had neutralizing antibodies against SARS-CoV-2. Among the cord blood samples, 91% had IgG antibodies, 9% had IgM antibodies, and 25% had neutralizing antibodies.

“It’s reassuring that, so far, the physiological response is exactly what we expected it to be,” Judette Louis, MD, MPH, an associate professor of ob.gyn. and the ob.gyn. department chair at the University of South Florida, Tampa, said in an interview. “It’s what we would expect, but it’s always helpful to have more data to support that. Otherwise, you’re extrapolating from what you know from other conditions,” said Dr. Louis, who moderated the oral abstracts session.

Symptomatic infection was associated with significantly higher IgG titers than asymptomatic infection (P = .03), but no correlation was seen for IgM or neutralizing antibodies. In addition, although mothers who delivered more than 28 days after their infection had higher IgG titers (P = .05), no differences existed in IgM or neutralizing response.

Infants’ cord blood titers were significantly lower than their corresponding maternal samples, independently of symptoms or latency from infection to delivery (P < .001), Dr. Joseph reported.

“Transplacental efficiency in other pathogens has been shown to be correlated with neonatal immunity when the ratio of cord to maternal blood is greater than 1,” Dr. Joseph said in her presentation. Their data showed “suboptimal efficiency” at a ratio of 0.81.

The study’s small sample size and lack of a control group were weaknesses, but a major strength was having a population at disproportionately higher risk for infection and severe morbidity than the general population.
 

 

 

Implications for maternal COVID-19 vaccination

Although the data are not yet available, Dr. Joseph said they have expanded their protocol to include vaccinated pregnant women.

“The key to developing an effective vaccine [for pregnant people] is in really characterizing adaptive immunity in pregnancy,” Dr. Joseph told SMFM attendees. “I think that these findings inform further vaccine development in demonstrating that maternal immunity is robust.”

The World Health Organization recently recommended withholding COVID-19 vaccines from pregnant people, but the SMFM and American College of Obstetricians and Gynecologists subsequently issued a joint statement reaffirming that the COVID-19 vaccines authorized by the FDA “should not be withheld from pregnant individuals who choose to receive the vaccine.”

“One of the questions people ask is whether in pregnancy you’re going to mount a good response to the vaccine the way you would outside of pregnancy,” Dr. Louis said. “If we can demonstrate that you do, that may provide the information that some mothers need to make their decisions.” Data such as those from Dr. Joseph’s study can also inform recommendations on timing of maternal vaccination.

“For instance, Dr. Joseph demonstrated that, 28 days out from the infection, you had more antibodies, so there may be a scenario where we say this vaccine may be more beneficial in the middle of the pregnancy for the purpose of forming those antibodies,” Dr. Louis said.
 

Consensus emerging from maternal antibodies data

The findings from Dr. Joseph’s study mirror those reported in a study published online Jan. 29 in JAMA Pediatrics. That study, led by Dustin D. Flannery, DO, MSCE, of Children’s Hospital of Philadelphia, also examined maternal and neonatal levels of IgG and IgM antibodies against the receptor binding domain of the SARS-CoV-2 spike protein. They also found a positive correlation between cord blood and maternal IgG concentrations (P < .001), but notably, the ratio of cord to maternal blood titers was greater than 1, unlike in Dr. Joseph’s study.

For their study, Dr. Flannery and colleagues obtained maternal and cord blood sera at the time of delivery from 1471 pairs of mothers and infants, independently of COVID status during pregnancy. The average maternal age was 32 years, and just over a quarter of the population (26%) were Black, non-Hispanic women. About half (51%) were White, 12% were Hispanic, and 7% were Asian.

About 6% of the women had either IgG or IgM antibodies at delivery, and 87% of infants born to those mothers had measurable IgG in their cord blood. No infants had IgM antibodies. As with the study presented at SMFM, the mothers’ infections included asymptomatic, mild, moderate, and severe cases, and the degree of severity of cases had no apparent effect on infant antibody concentrations. Most of the women who tested positive for COVID-19 (60%) were asymptomatic.

Among the 11 mothers who had antibodies but whose infants’ cord blood did not, 5 had only IgM antibodies, and 6 had significantly lower IgG concentrations than those seen in the other mothers.

In a commentary about the JAMA Pediatrics study, Flor Munoz, MD, of the Baylor College of Medicine, Houston, suggested that the findings are grounds for optimism about a maternal vaccination strategy to protect infants from COVID-19.

“However, the timing of maternal vaccination to protect the infant, as opposed to the mother alone, would necessitate an adequate interval from vaccination to delivery (of at least 4 weeks), while vaccination early in gestation and even late in the third trimester could still be protective for the mother,” Dr. Munoz wrote.

Given the interval between two-dose vaccination regimens and the fact that transplacental transfer begins at about the 17th week of gestation, “maternal vaccination starting in the early second trimester of gestation might be optimal to achieve the highest levels of antibodies in the newborn,” Dr. Munoz wrote. But questions remain, such as how effective the neonatal antibodies would be in protecting against COVID-19 and how long they last after birth.

No external funding was used in Dr. Joseph’s study. Dr. Joseph and Dr. Louis have disclosed no relevant financial relationships. The JAMA Pediatrics study was funded by the Children’s Hospital of Philadelphia. One coauthor received consultancy fees from Sanofi Pasteur, Lumen, Novavax, and Merck unrelated to the study. Dr. Munoz served on the data and safety monitoring boards of Moderna, Pfizer, Virometix, and Meissa Vaccines and has received grants from Novavax Research and Gilead Research.

Disparities in child abuse evaluation arise from implicit bias

Black and Latinx children are more likely to be evaluated for child abuse and referred to child protective services than their White peers, according to research discussed by Tiffani J. Johnson, MD, an assistant professor of emergency medicine at the University of California, Davis.

“These disparities in child abuse evaluation and reporting are bidirectional,” she said. “We also recognize that abuse is more likely to be unrecognized in White children.”

Dr. Johnson presented data on the health disparities in child abuse reporting in a session at the annual meeting of the American Academy of Pediatrics, held virtually this year. Health care disparities, as defined by the National Academy of Sciences, refers to differences in the quality of care between minority and nonminority populations that are not caused by clinical appropriateness, access, need, or patient preference, she explained. Instead, they result from discrimination, bias, stereotyping, and uncertainty.
 

Disparities lead to harm in all children

For example, a 2018 systematic review found that Black and other non-White children were significantly more likely than White children to be evaluated with a skeletal survey. In one of the studies included, at a large urban academic center, Black and Latinx children with accidental fractures were 8.75 times more likely to undergo a skeletal survey than White children and 4.3 times more likely to be reported to child protective services.

“And let me emphasize that these are children who were ultimately found to have accidental fractures,” Dr. Johnson said.

Meanwhile, in an analysis of known cases of head trauma, researchers found that abuse was missed in 37% of White children, compared with 19% of non-White children.

“These only represent the tip of the iceberg as a true number of cases of abuse may never really be detected because some cases are still unknown,” Dr. Johnson told attendees. And the harm of these disparities runs in both directions.

“Failing to diagnose abuse in White children clearly puts them at increased risk for return visits and return evaluations for repeated abuse by the perpetrators,” she said. But harm also can result from overreporting and investigation, including psychological trauma and a waste of limited resources. Overinvestigation also can erode family-physician relationships and perpetuate distrust of medical care in communities of color.

Yet at the same time, it’s clear that Black children, adolescents, and young adults are not protected from harm in society more generally, when at home, where they learn, or where they play, Dr. Johnson said, referencing the deaths of Breonna Taylor and Tamir Rice as examples.

“And now we’re seeing increased evidence that children are not protected in the health care center when we think about the many disparities that have been identified in the care and outcomes of children, including the disproportionality in terms of child abuse evaluation and referrals,” Dr. Johnson said.

Racism is a root cause of that harm to Black children, she said, as the systemic structure of opportunities unfairly disadvantages some individuals and communities while unfairly advantaging others, thereby “sapping the strength of the whole society through the waste of human resources.”

Tonya Chaffee, MD, MPH, a clinical professor of health sciences at the University of California, San Francisco, who attended the session, said she particularly appreciated “seeing data on which racial/ethnic populations have child abuse reports made and the disparities that exist that are similar to what we are noticing in our own institution.”
 

 

 

Role of individual-level implicit bias and racism

While institutional and structural racism play a substantial role in health care disparities, Dr. Johnson focused primarily on the impact of personal racism when it comes to child abuse evaluations, through overt discrimination, explicit bias, implicit bias, and stigmatization. The most challenging of these to identify and acknowledge is often implicit bias, a tendency to believe, even unconsciously, that some people or ideas are better than others, which results in unfair treatment.

For example, a 2016 study found that half of medical students and residents held at least one biological belief about differences between Black and White individuals that was actually false, such as Black people having more pain tolerance or stronger bones than White people, which then affected treatment recommendations.

“Implicit bias refers to our attitudes that lie below the surface, but they can still influence our behaviors,” Dr. Johnson explained. She encouraged providers to take the implicit bias test online to learn about their own unrecognized implicit biases. These biases have a hand in influencing decisions particularly in fast-paced environments where cognitive load is high – such as EDs, where many child abuse evaluations occur.

For example, in one study Dr. Johnson led, the researchers measured implicit bias in participants before and after an ED shift to assess how cognitive load affected bias. They found that participants who care for more than 10 patients, the average score for implicit bias increased.

Similarly, “when the ED was more overcrowded, there was also increased bias at the end of the shift, compared to the beginning of the shift,” Dr. Johnson said. She asked clinicians to take into consideration that at the start of the shift, they may feel well rested and freshly caffeinated, able to suppress or overcome the biases that they know they have.

“But our biases [are] more likely to come into play with every subsequent decision that we make throughout the day when we’re engaged in clinical encounters,” such as who does and does not receive a skeletal survey or get referred to child protective services, she said.

In another study where she hypothesized that resident physicians would have less bias on the child race implicit bias test than on the adult race one, Dr. Johnson reported that 85% of 91 residents working in an ED had an implicit pro-White/anti-Black bias in the test on adult race, but an even higher bias score – 91% – with child race.

Research has found that even children’s names can conjure implicit bias when it comes to stereotypically “White-sounding” names versus stereotypically “Black-sounding names.”

The implicit bias among clinicians extends beyond care of different children. Research has also identified association between higher implicit bias scores and less interpersonal treatment, less supportive communication, less patient-centered communication, poorer patient ratings of satisfaction, and greater patient-reported difficulty with following recommendations, Dr. Johnson said.

“I want you to think about that because I know that when we’re engaging with parents and making decisions about whether or not we’re going to do a skeletal survey or report someone for it, there is a lot of subjectivity that comes into play with how you’re interacting with families,” Dr. Johnson said. Those verbal and nonverbal cues may be triggering to parents, which then affects your interaction with them. Further, research shows that these biases may impact treatment decisions as well.

Personal-mediated racism also shows up in the use of stigmatizing language, Dr. Johnson said.

“When providers read stigmatizing language in the patient’s medical records, it was associated with them having more negative attitudes about that patient,” which then influenced their clinical decision-making, she said. “So when providers got primed with stigmatizing language, they subsequently had less aggressive pain management for those patients.”
 

 

 

Clinical implications for patient care

Dr. Johnson encouraged attendees to be careful about the language and tone they use in communicating with other health care providers and during documentation in medical records. Disparities in child abuse evaluation and reporting tend to be greater in EDs with more subjective conditions, whereas disparities are lower in departments with more established protocols.

She recommended several changes to practice that can reduce the impact of implicit bias. Universal screening for child abuse can increase how many injuries are found, but usually at the cost of increased resources and radiation. Another option is use of validated clinical decision support rules to identify who is at high or low risk for maltreatment, something Dr. Johnson is working on in her research.

But it’s also important for individual providers to confront their personal biases. Evidence-based strategies for reducing bias include perspective taking, focusing on common identities with patients, using counter-stereotypical imaging, seeking increased opportunity for cross-cultural contact, and mindfulness meditation.

“When you interact with people of different backgrounds, it helps to reduce the impact of stereotypes in society about those individuals,” Dr. Johnson told attendees. It’s also important to recognize how diversity in your clinical team can reduce bias.

“We need to work with our institutions to confront racial biases in child abuse reporting and develop quality improvement projects to ensure reporting is done objectively,” Dr. Chaffee said in an interview after attending the session. “This will require training and likely policy changes, including how reports are made to child welfare and/or the police moving forward.”
