Critical care and COVID-19: Dr. Matt Aldrich
Matt Aldrich, MD, is an anesthesiologist and medical director of critical care at UCSF Health in San Francisco. Robert Wachter, MD,MHM, spoke with him about critical care issues in COVID-19, including clinical presentation, PPE in the ICU, whether the health system has enough ventilators for a surge, and ethical dilemmas that ICUs may face during the pandemic.

Before the COVID-19 surge hits your facility, take steps to boost capacity
, according to a physician leader and a health workforce expert.
Polly Pittman, PhD, is hearing a lot of concern among health care workers that it’s difficult to find definitive and accurate information about how best to protect themselves and their families, she said during a webinar by the Alliance for Health Policy titled Health System Capacity: Protecting Frontline Health Workers. “The knowledge base is evolving very quickly,” said Dr. Pittman, Fitzhugh Mullan Professor of Health Workforce Equity at the Milken Institute School of Public Health, George Washington University, Washington.
Stephen Parodi, MD, agreed that effective communication is job one in the health care workplace during the crisis. “I can’t stress enough ... that communications are paramount and you can’t overcommunicate,” said Dr. Parodi, executive vice president of external affairs, communications, and brand at the Permanente Federation and associate executive director of the Permanente Medical Group, Vallejo, Calif.
“We’re in a situation of confusion and improvisation right now,” regarding protection of health care workers, said Dr. Pittman. The potential exists for “a downward spiral where you have the lack of training, the shortages in terms of protective gear, weakening of guidelines, and confusion regarding guidelines at federal level, creating a potential cascade” that may result in “moral distress and fatigue. ... That’s not occurring now, but that’s the danger” unless the personal protective equipment (PPE) situation is adequately addressed very soon, she said.
Dr. Pittman also pointed out the concerns that many of the 18 million U.S. health care workers have for their families should they themselves fall ill or transmit coronavirus to family members. “The danger exists of a mass exodus. People don’t have to show up at work, and they won’t show up at work if they don’t feel supported and safe.”
Dr. Parodi said that the Permanente organization is on a better footing than many workplaces. “We actually had an early experience because of the work that we did to support the Diamond Princess cruise ship evacuees from Yokahama in February.” That ship was quarantined upon arrival in Yokahama on Feb. 3 because a passenger had a confirmed test for SARS-CoV-2 infection, and a quarter of the 428 Americans on board subsequently tested positive. Most of them were evacuated to California or Texas. “That actually gave us the experience for providing care within the hospital setting – and also for containment strategies,” he said.
“We quickly understood that we needed to move to a mitigation strategy,” said Dr. Parodi. Use of PPE has been “tailored for how the virus is spread.” In the absence of the risk of aerosol transmission from certain procedures, health care workers use gowns, gloves, surgical masks, and goggles.
Because of anticipated “supply chain shortfalls,” Dr. Parodi said that his organization implemented Centers for Disease Control and Prevention guidelines for reuse and extended use of N95 respirators early on. “Even if you’re not in a locale that’s been hit, you need to be on wartime footing for preserving PPE.”
Telehealth, said Dr. Parodi, has been implemented “in a huge way” throughout the Permanente system. “We have reduced primary care visits by 90% in the past week, and also subspecialty visits by 50%. … A large amount of the workforce can work from home. We turned off elective surgeries more than a week ago to reduce the number of patients who are requiring intensive care.” Making these changes means the organization is more prepared now for a surge they expect in the coming weeks.
Dr. Pittman voiced an opinion widely shared by those who are implementing large-scale telehealth efforts “We’re going to learn a lot. Many of the traditional doctor-patient visits can be done by telemedicine in the future.”
Knowledge about local trends in infection rates is key to preparedness. “We’ve ramped up testing, to understand what’s happening in the community,” said Dr. Parodi, noting that test turnaround time is currently running 8-24 hours. Tightening up this window can free up resources when an admitted patient’s test is negative.
Still, some national projections forecast a need for hospital beds at two to three times current capacity – or even more, said Dr. Parodi.
He noted that Permanente is “working hand in glove with state authorities throughout the country.” Efforts include establishing alternative sites for assessment and testing, as well as opening up closed hospitals and working with the National Guard and the Department of Defense to prepare mobile hospital units that can be deployed in areas with peak infection rates. “Having all of those options available to us is critically important,” he said.
To mitigate potential provider shortages, Dr. Pittman said, “All members of the care team could potentially do more” than their current licenses allow. Expanding the scope of practice for pharmacists, clinical laboratory staff, licensed practical nurses, and medical assistants can help with efficient care delivery.
Other measures include expedited licensing for near-graduates and nonpracticing foreign medical graduates, as well as relicensing for retired health care personnel and those who are not currently working directly with patients, she said.
Getting these things done “requires leadership on behalf of the licensing bodies,” as well as coordination with state regulatory authorities, Dr. Pittman pointed out.
Dr. Parodi called for state and federal governments to implement emergency declarations that suspend some existing health codes to achieve repurposing of staff. Getting these measures in place now will allow facilities “to be able to provide that in-time training now before the surge occurs. ... We are actively developing plans knowing that there’s going to be a need for more critical care.”
The game plan at Permanente, he said, is to repurpose critical care physicians to provide consultations to multiple hospitalists who are providing the bulk of frontline care. At the same time, they plan to repurpose other specialists to backfill the hospitalists, and to repurpose family medicine physicians to supplement staff in emergency departments and other frontline intake areas.
All the organizational measures being taken won’t be in vain if they increase preparedness for the long battle ahead, he said. “We need to double down on the work. ... We need to continue social distancing, and we’ve got to ramp up testing. Until we do that we have to hold the line on basic public health measures.”
Dr. Parodi is employed by Permanente. The panelists reported no disclosures relevant to the presentation, which was sponsored by the Alliance for Health Policy, the Commonwealth Fund, and the National Institute for Health Care Management Foundation.

REPORTING FROM AN ALLIANCE FOR HEALTH POLICY WEBINAR
FDA okays emergency use of convalescent plasma for seriously ill COVID-19 patients
As the proportion of patients infected with COVID-19 continues to rise in the United States, the Food and Drug Administration is facilitating access to COVID-19 convalescent plasma for use in patients with serious or immediately life-threatening COVID-19 infections.
While clinical trials are underway to evaluate the safety and efficacy of administering convalescent plasma to patients with COVID-19, the FDA is granting clinicians permission for use of investigational convalescent plasma under single-patient emergency Investigational New Drug Applications (INDs), since no known cure exists and a vaccine is more than 1 year away from becoming available.
This allows the use of an investigational drug for the treatment of an individual patient by a licensed physician upon FDA authorization. This does not include the use of COVID-19 convalescent plasma for the prevention of infection, according to a statement issued by the agency on March 24.
“It is possible that convalescent plasma that contains antibodies to SARS-CoV-2 (the virus that causes COVID-19) might be effective against the infection,” the FDA statement reads. “Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including the 2009-2010 H1N1 influenza virus pandemic, 2003 SARS-CoV-1 epidemic, and the 2012 MERS-CoV epidemic. Although promising, convalescent plasma has not been shown to be effective in every disease studied.”
“I think the FDA got caught initially a little flat-footed when it came to the development of COVID-19 tests, but they’re quickly catching up,” Peter J. Pitts, who was the FDA’s associate commissioner from 2002 to 2004, said in an interview. “I think that the attitude now is, ‘If it’s safe, let’s create a pathway to see how these things work in the real world.’ I think that’s going to be as true for treatments to lessen the symptoms and shorten the duration of the disease, as well as convalescent plasma as a potential alternative to a yet-to-be-developed vaccine.”
At the University of Washington School of Medicine, Seattle, Terry B. Gernsheimer, MD, and her colleagues are recruiting recovered COVID-19 patients to donate plasma for seriously ill patients affected with the virus. “The thought of using convalescent plasma makes total sense, because it’s immediately available, and it’s something that we can try to give people,” said Dr. Gernsheimer, a hematologist who is professor of medicine at the medical school. “It’s been used in China, and reports should be coming out shortly about their experience with this.”
In a case series that appeared in JAMA on March 27 (doi: 10.1001/jama.2020.4783), Chinese researchers led by Chenguang Shen, PhD, reported findings from five critically ill COVID-19 patients with acute respiratory distress syndrome who received a transfusion with convalescent plasma at Shenzhen Third People’s Hospital 10 and 22 days after hospital admission. The patients ranged in age from 36 to 73 years, three were men, and all were receiving mechanical ventilation at the time of treatment.
Dr. Shen and colleagues reported that viral loads decreased and became negative within 12 days following the transfusion. Three of the patients were discharged from the hospital after a length of stay that ranged from 51 to 55 days, and two remain in stable condition at 37 days after the transfusion. The researchers pointed out that all patients received antiviral agents, including interferon and lopinavir/ritonavir, during and following convalescent plasma treatment, “which also may have contributed to the viral clearance observed.”
Under the FDA policy on emergency IND use, COVID-19 convalescent plasma must only be collected from recovered individuals if they are eligible to donate blood, required testing must be performed, and the donation must be found suitable.
Potential donors “are going to be screened the way all blood donors are screened,” Dr. Gernsheimer said. “It’s not going to be any less safe than any unit of plasma that’s on the shelf that comes from our volunteer donors. There are always transfusion reactions that we have to worry about, [and] there are potentially unknown pathogens that we don’t yet know about that we are not yet testing for. It’s the regular risk we see with any unit of plasma.”
She added that COVID-19 survivors appear to start increasing their titer of the antibody around day 28. “We’ll be looking for recovered individuals who have had a documented infection, and whose symptoms started about 28 days before we collect,” she said.
The FDA advises clinicians to address several considerations for donor eligibility, including prior diagnosis of COVID-19 documented by a laboratory test; complete resolution of symptoms at least 14 days prior to donation; female donors negative for HLA antibodies or male donors, and negative results for COVID-19 either from one or more nasopharyngeal swab specimens or by a molecular diagnostic test from blood. [A partial list of available tests can be accessed on the FDA website.] The agency also advises that donors have defined SARS-CoV-2–neutralizing antibody titers, if testing can be conducted (optimally greater than 1:320).
Patients eligible to receive COVID-19 convalescent plasma must have a severe or immediately life-threatening infection with laboratory-confirmed COVID-19. The agency defines severe disease as dyspnea, respiratory frequency of 30 per minute or greater, blood oxygen saturation of 93% or less, partial pressure of arterial oxygen to fraction of inspired oxygen ratio of less than 300, and/or lung infiltrates of greater than 50% within 24-48 hours. Life-threatening disease is defined as respiratory failure, septic shock, and/or multiple organ dysfunction or failure. Patients must provide informed consent.
The potential risks of receiving COVID-19 convalescent plasma remain unknown, according to Dr. Gernsheimer. “What some people have thought about is, could there be such an inflammatory response with the virus that we would initially see these patients get worse?” she said. “My understanding is that has not occurred in China yet, but we don’t have all those data. But we always worry if we have something that’s going to cause inflammation around an infection, for example, that could initially make it more difficult to breathe if it’s a lung infection. So far, my understanding is that has not been seen.”
For COVID-19 convalescent plasma authorization requests that require a response within 4-8 hours, requesting clinicians may complete form 3296 and submit it by email to [email protected].
For COVID-19 convalescent plasma authorization requests that require a response in less than 4 hours, or if the clinician is unable to complete and submit form 3926 because of extenuating circumstances, verbal authorization can be sought by calling the FDA’s Office of Emergency Operations at 1-866-300-4374.
The FDA is working with the National Institutes of Health, the Centers for Disease Control and Prevention, and other government partners to develop protocols for use by multiple investigators in order to coordinate the collection and use of COVID-19 convalescent plasma.
“It’s crucial that data be captured for every patient so that we really understand what safety and effectiveness looks like on as close to a real-world level as we can, as quickly as we can,” said Mr. Pitts, who is president and cofounder of the Center for Medicine in the Public Interest, and who also does consulting work for the FDA. “I understand that health care professionals are overworked and overburdened right now. I applaud them for their heroic work. But that doesn’t mean that we can shirk off collecting the data. When I was at the FDA, I helped address the SARS epidemic. The agency attitude at that point was, ‘Let’s get things that just might work through the process, as long as the cure isn’t going to be worse than the disease.’ I think that’s the attitude that’s leading the charge today.”

While clinical trials are underway to evaluate the safety and efficacy of administering convalescent plasma to patients with COVID-19, the FDA is granting clinicians permission for use of investigational convalescent plasma under single-patient emergency Investigational New Drug Applications (INDs), since no known cure exists and a vaccine is more than 1 year away from becoming available.
This allows the use of an investigational drug for the treatment of an individual patient by a licensed physician upon FDA authorization. This does not include the use of COVID-19 convalescent plasma for the prevention of infection, according to a statement issued by the agency on March 24.
“It is possible that convalescent plasma that contains antibodies to SARS-CoV-2 (the virus that causes COVID-19) might be effective against the infection,” the FDA statement reads. “Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including the 2009-2010 H1N1 influenza virus pandemic, 2003 SARS-CoV-1 epidemic, and the 2012 MERS-CoV epidemic. Although promising, convalescent plasma has not been shown to be effective in every disease studied.”
“I think the FDA got caught initially a little flat-footed when it came to the development of COVID-19 tests, but they’re quickly catching up,” Peter J. Pitts, who was the FDA’s associate commissioner from 2002 to 2004, said in an interview. “I think that the attitude now is, ‘If it’s safe, let’s create a pathway to see how these things work in the real world.’ I think that’s going to be as true for treatments to lessen the symptoms and shorten the duration of the disease, as well as convalescent plasma as a potential alternative to a yet-to-be-developed vaccine.”
At the University of Washington School of Medicine, Seattle, Terry B. Gernsheimer, MD, and her colleagues are recruiting recovered COVID-19 patients to donate plasma for seriously ill patients affected with the virus. “The thought of using convalescent plasma makes total sense, because it’s immediately available, and it’s something that we can try to give people,” said Dr. Gernsheimer, a hematologist who is professor of medicine at the medical school. “It’s been used in China, and reports should be coming out shortly about their experience with this.”
In a case series that appeared in JAMA on March 27 (doi: 10.1001/jama.2020.4783), Chinese researchers led by Chenguang Shen, PhD, reported findings from five critically ill COVID-19 patients with acute respiratory distress syndrome who received a transfusion with convalescent plasma at Shenzhen Third People’s Hospital 10 and 22 days after hospital admission. The patients ranged in age from 36 to 73 years, three were men, and all were receiving mechanical ventilation at the time of treatment.
Dr. Shen and colleagues reported that viral loads decreased and became negative within 12 days following the transfusion. Three of the patients were discharged from the hospital after a length of stay that ranged from 51 to 55 days, and two remain in stable condition at 37 days after the transfusion. The researchers pointed out that all patients received antiviral agents, including interferon and lopinavir/ritonavir, during and following convalescent plasma treatment, “which also may have contributed to the viral clearance observed.”
Under the FDA policy on emergency IND use, COVID-19 convalescent plasma must only be collected from recovered individuals if they are eligible to donate blood, required testing must be performed, and the donation must be found suitable.
Potential donors “are going to be screened the way all blood donors are screened,” Dr. Gernsheimer said. “It’s not going to be any less safe than any unit of plasma that’s on the shelf that comes from our volunteer donors. There are always transfusion reactions that we have to worry about, [and] there are potentially unknown pathogens that we don’t yet know about that we are not yet testing for. It’s the regular risk we see with any unit of plasma.”
She added that COVID-19 survivors appear to start increasing their titer of the antibody around day 28. “We’ll be looking for recovered individuals who have had a documented infection, and whose symptoms started about 28 days before we collect,” she said.
The FDA advises clinicians to address several considerations for donor eligibility, including prior diagnosis of COVID-19 documented by a laboratory test; complete resolution of symptoms at least 14 days prior to donation; female donors negative for HLA antibodies or male donors, and negative results for COVID-19 either from one or more nasopharyngeal swab specimens or by a molecular diagnostic test from blood. [A partial list of available tests can be accessed on the FDA website.] The agency also advises that donors have defined SARS-CoV-2–neutralizing antibody titers, if testing can be conducted (optimally greater than 1:320).
Patients eligible to receive COVID-19 convalescent plasma must have a severe or immediately life-threatening infection with laboratory-confirmed COVID-19. The agency defines severe disease as dyspnea, respiratory frequency of 30 per minute or greater, blood oxygen saturation of 93% or less, partial pressure of arterial oxygen to fraction of inspired oxygen ratio of less than 300, and/or lung infiltrates of greater than 50% within 24-48 hours. Life-threatening disease is defined as respiratory failure, septic shock, and/or multiple organ dysfunction or failure. Patients must provide informed consent.
The potential risks of receiving COVID-19 convalescent plasma remain unknown, according to Dr. Gernsheimer. “What some people have thought about is, could there be such an inflammatory response with the virus that we would initially see these patients get worse?” she said. “My understanding is that has not occurred in China yet, but we don’t have all those data. But we always worry if we have something that’s going to cause inflammation around an infection, for example, that could initially make it more difficult to breathe if it’s a lung infection. So far, my understanding is that has not been seen.”
For COVID-19 convalescent plasma authorization requests that require a response within 4-8 hours, requesting clinicians may complete form 3296 and submit it by email to [email protected].
For COVID-19 convalescent plasma authorization requests that require a response in less than 4 hours, or if the clinician is unable to complete and submit form 3926 because of extenuating circumstances, verbal authorization can be sought by calling the FDA’s Office of Emergency Operations at 1-866-300-4374.
The FDA is working with the National Institutes of Health, the Centers for Disease Control and Prevention, and other government partners to develop protocols for use by multiple investigators in order to coordinate the collection and use of COVID-19 convalescent plasma.
“It’s crucial that data be captured for every patient so that we really understand what safety and effectiveness looks like on as close to a real-world level as we can, as quickly as we can,” said Mr. Pitts, who is president and cofounder of the Center for Medicine in the Public Interest, and who also does consulting work for the FDA. “I understand that health care professionals are overworked and overburdened right now. I applaud them for their heroic work. But that doesn’t mean that we can shirk off collecting the data. When I was at the FDA, I helped address the SARS epidemic. The agency attitude at that point was, ‘Let’s get things that just might work through the process, as long as the cure isn’t going to be worse than the disease.’ I think that’s the attitude that’s leading the charge today.”
Reports suggest possible in utero transmission of novel coronavirus 2019
Reports of three neonates with elevated IgM antibody concentrations whose mothers had COVID-19 in two articles raise questions about whether the infants may have been infected with the virus in utero.
The data, while provocative, “are not conclusive and do not prove in utero transmission” of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), editorialists cautioned.
“The suggestion of in utero transmission rests on IgM detection in these 3 neonates, and IgM is a challenging way to diagnose many congenital infections,” David W. Kimberlin, MD, and Sergio Stagno, MD, of the division of pediatric infectious diseases at University of Alabama at Birmingham, wrote in their editorial. “IgM antibodies are too large to cross the placenta and so detection in a newborn reasonably could be assumed to reflect fetal production following in utero infection. However, most congenital infections are not diagnosed based on IgM detection because IgM assays can be prone to false-positive and false-negative results, along with cross-reactivity and testing challenges.”
None of the three infants had a positive reverse transcriptase–polymerase chain reaction (RT-PCR) test result, “so there is not virologic evidence for congenital infection in these cases to support the serologic suggestion of in utero transmission,” the editorialists noted.
Examining the possibility of vertical transmission
A prior case series of nine pregnant women found no transmission of the virus from mother to child, but the question of in utero transmission is not settled, said Lan Dong, MD, of the department of obstetrics and gynecology at Renmin Hospital of Wuhan University in China and colleagues. In their research letter, the investigators described a newborn with elevated IgM antibodies to novel coronavirus 2019 born to a mother with COVID-19. The infant was delivered by cesarean section February 22, 2020, at Renmin Hospital in a negative-pressure isolation room.
“The mother wore an N95 mask and did not hold the infant,” the researchers said. “The neonate had no symptoms and was immediately quarantined in the neonatal intensive care unit. At 2 hours of age, the SARS-CoV-2 IgG level was 140.32 AU/mL and the IgM level was 45.83 AU/mL.” Although the infant may have been infected at delivery, IgM antibodies usually take days to appear, Dr. Dong and colleagues wrote. “The infant’s repeatedly negative RT-PCR test results on nasopharyngeal swabs are difficult to explain, although these tests are not always positive with infection. ... Additional examination of maternal and newborn samples should be done to confirm this preliminary observation.”
A review of infants’ serologic characteristics
Hui Zeng, MD, of the department of laboratory medicine at Zhongnan Hospital of Wuhan University in China and colleagues retrospectively reviewed clinical records and laboratory results for six pregnant women with COVID-19, according to a study in JAMA. The women had mild clinical manifestations and were admitted to Zhongnan Hospital between February 16 and March 6. “All had cesarean deliveries in their third trimester in negative pressure isolation rooms,” the investigators said. “All mothers wore masks, and all medical staff wore protective suits and double masks. The infants were isolated from their mothers immediately after delivery.”
Two of the infants had elevated IgG and IgM concentrations. IgM “is not usually transferred from mother to fetus because of its larger macromolecular structure. ... Whether the placentas of women in this study were damaged and abnormal is unknown,” Dr. Zeng and colleagues said. “Alternatively, IgM could have been produced by the infant if the virus crossed the placenta.”
“Although these 2 studies deserve careful evaluation, more definitive evidence is needed” before physicians can “counsel pregnant women that their fetuses are at risk from congenital infection with SARS-CoV-2,” Dr. Kimberlin and Dr. Stagno concluded.
Dr. Dong and associates had no conflicts of interest. Their work was supported by the National Key Research and Development Project and others. Dr. Zeng and colleagues had no relevant financial disclosures. Their study was supported by grants from the National Natural Science Foundation of China and Zhongnan Hospital. Dr. Kimberlin and Dr. Stagno had no conflicts of interest.

Despite strict controls, some infants born to mothers with COVID-19 appear infected
Despite implementation of strict infection control and prevention procedures in a hospital in Wuhan, China,
according to Lingkong Zeng, MD, of the department of neonatology at Wuhan Children’s Hospital, and associates.Thirty-three neonates born to mothers with COVID-19 were included in the study, published as a research letter in JAMA Pediatrics. Of this group, three neonates (9%) were confirmed to be infected with the novel coronavirus 2019 at 2 and 4 days of life through nasopharyngeal and anal swabs.
Of the three infected neonates, two were born at 40 weeks’ gestation and the third was born at 31 weeks. The two full-term infants had mild symptoms such as lethargy and fever and were negative for the virus at 6 days of life. The preterm infant had somewhat worse symptoms, but the investigators acknowledged that “the most seriously ill neonate may have been symptomatic from prematurity, asphyxia, and sepsis, rather than [the novel coronavirus 2019] infection.” They added that outcomes for all three neonates were favorable, consistent with past research.
“Because strict infection control and prevention procedures were implemented during the delivery, it is likely that the sources of [novel coronavirus 2019] in the neonates’ upper respiratory tracts or anuses were maternal in origin,” Dr. Zeng and associates surmised.
While previous studies have shown no evidence of COVID-19 transmission between mothers and neonates, and all samples, including amniotic fluid, cord blood, and breast milk, were negative for the novel coronavirus 2019, “vertical maternal-fetal transmission cannot be ruled out in the current cohort. Therefore, it is crucial to screen pregnant women and implement strict infection control measures, quarantine of infected mothers, and close monitoring of neonates at risk of COVID-19,” the investigators concluded.
The study authors reported that they had no conflicts of interest.

HCV screening risk factors in pregnant women need updating
“Because risk-factor screening has obvious limitations, universal screening in pregnancy has been suggested to allow for linkage to postpartum care and identification of children for future testing and treatment,” wrote Mona Prasad, DO, of Ohio State University, Columbus, and colleagues.
In a study published in Obstetrics & Gynecology, the researchers reviewed data from women with singleton pregnancies presenting for prenatal care prior to 23 weeks’ gestation during 2012-2015. Of these, 254 tested positive for the hepatitis C virus (HCV) antibody, for a seroprevalence rate of 2.4 cases per 1,000 women.
The researchers conducted a case-control analysis of 131 women who tested positive and 251 controls to identify HCV infection risk factors based on interviews and chart reviews. They found that risk factors significantly associated with positive HCV antibodies included injection drug use (adjusted odds ratio, 22.9), a history of blood transfusion (aOR, 3.7), having an HCV-infected partner (aOR, 6.3), having had more than three sexual partners (aOR, 5.3), and smoking during pregnancy (aOR, 2.4).
In an unadjusted analysis, the researchers confirmed two of the risk factors currently recommended by the Centers for Disease Control and Prevention for screening for HCV: injection drug use and being born to a mother with HCV infection, but not dialysis, organ transplantation, or HIV infection.
“Our results demonstrate that current risk factors could be contemporized,” Dr. Prasad and colleagues noted. “The currently accepted risk factors such as exposure to clotting factors, dialysis, and organ transplants are unlikely to be found. A thorough assessment of injection drug use history, smoking, transfusions, number of sexual partners, and partners with HCV infection is more sensitive in an obstetric population.”
The study findings were limited by several factors including possible selection bias and inclusion of only 65% of eligible women who were HCV positive, as well as a lack of screening data from 2016 to the present, which may not reflect the impact of the recent opioid epidemic, the researchers noted. However, the results were strengthened by the large sample size, and the generalizability of the study population.
“Our results regarding prevalence rates and risk factors of HCV antibody among pregnant women in the United States will be valuable to policymakers as they weigh the costs and benefits of universal screening,” Dr. Prasad and associates concluded.
Although universal screening has the potential to be more cost effective, given the small population of pregnant women eligible for treatment and lack of an available treatment, “the rationale is weaker for unique universal HCV screening recommendations for pregnant women,” they said.
By contrast, Sammy Saab, MD, MPH, of the University of California, Los Angeles; Ravina Kullar, PharmD, MPH, of Gilead Sciences, Foster City, Calif.; and Prabhu Gounder, MD, MPH, of the Los Angeles Department of Public Health, wrote an accompanying commentary in favor of universal HCV screening for pregnant women, in part because of the increase in HCV in the younger population overall.
“For many women of reproductive age, pregnancy is one of their few points of contact with their health care provider; therefore, pregnancy could provide a crucial time for targeting this population,” they noted.
Risk-based screening is of limited effectiveness because patients are not identified by way of current screening tools or they decline to reveal risk factors that providers might miss, the editorialists said. Pregnancy has not been shown to affect the accuracy of HCV tests, and identifying infections in mothers allows for screening in children as well.
“The perinatal hepatitis B virus infection program, which has been implemented in several state and local public health departments, could serve as an example for how to conduct surveillance for mothers with HCV infection and to ensure that HCV-exposed children receive appropriate follow-up testing and linkage to care,” the editorialists concluded.
The study was supported in part by multiple grants from the National Institute of Child Health and Human Development. Dr. Prasad disclosed funding from Ohio State University and from Gilead. Coauthors had links with pharmaceutical companies, associations, and organizations – most unrelated to this study. The editorialists had no financial conflicts to disclose.

“Because risk-factor screening has obvious limitations, universal screening in pregnancy has been suggested to allow for linkage to postpartum care and identification of children for future testing and treatment,” wrote Mona Prasad, DO, of Ohio State University, Columbus, and colleagues.
In a study published in Obstetrics & Gynecology, the researchers reviewed data from women with singleton pregnancies presenting for prenatal care prior to 23 weeks’ gestation during 2012-2015. Of these, 254 tested positive for the hepatitis C virus (HCV) antibody, for a seroprevalence rate of 2.4 cases per 1,000 women.
The researchers conducted a case-control analysis of 131 women who tested positive and 251 controls to identify HCV infection risk factors based on interviews and chart reviews. They found that risk factors significantly associated with positive HCV antibodies included injection drug use (adjusted odds ratio, 22.9), a history of blood transfusion (aOR, 3.7), having an HCV-infected partner (aOR, 6.3), having had more than three sexual partners (aOR, 5.3), and smoking during pregnancy (aOR, 2.4).
In an unadjusted analysis, the researchers confirmed two of the risk factors currently recommended by the Centers for Disease Control and Prevention for screening for HCV: injection drug use and being born to a mother with HCV infection, but not dialysis, organ transplantation, or HIV infection.
“Our results demonstrate that current risk factors could be contemporized,” Dr. Prasad and colleagues noted. “The currently accepted risk factors such as exposure to clotting factors, dialysis, and organ transplants are unlikely to be found. A thorough assessment of injection drug use history, smoking, transfusions, number of sexual partners, and partners with HCV infection is more sensitive in an obstetric population.”
The study findings were limited by several factors including possible selection bias and inclusion of only 65% of eligible women who were HCV positive, as well as a lack of screening data from 2016 to the present, which may not reflect the impact of the recent opioid epidemic, the researchers noted. However, the results were strengthened by the large sample size, and the generalizability of the study population.
“Our results regarding prevalence rates and risk factors of HCV antibody among pregnant women in the United States will be valuable to policymakers as they weigh the costs and benefits of universal screening,” Dr. Prasad and associates concluded.
Although universal screening has the potential to be more cost effective, given the small population of pregnant women eligible for treatment and lack of an available treatment, “the rationale is weaker for unique universal HCV screening recommendations for pregnant women,” they said.
By contrast, Sammy Saab, MD, MPH, of the University of California, Los Angeles; Ravina Kullar, PharmD, MPH, of Gilead Sciences, Foster City, Calif.; and Prabhu Gounder, MD, MPH, of the Los Angeles Department of Public Health, wrote an accompanying commentary in favor of universal HCV screening for pregnant women, in part because of the increase in HCV in the younger population overall.
“For many women of reproductive age, pregnancy is one of their few points of contact with their health care provider; therefore, pregnancy could provide a crucial time for targeting this population,” they noted.
Risk-based screening is of limited effectiveness because patients are not identified by way of current screening tools or they decline to reveal risk factors that providers might miss, the editorialists said. Pregnancy has not been shown to affect the accuracy of HCV tests, and identifying infections in mothers allows for screening in children as well.
“The perinatal hepatitis B virus infection program, which has been implemented in several state and local public health departments, could serve as an example for how to conduct surveillance for mothers with HCV infection and to ensure that HCV-exposed children receive appropriate follow-up testing and linkage to care,” the editorialists concluded.

HIV shortens life expectancy 9 years, healthy life expectancy 16 years
Despite highly effective antiretroviral therapy, HIV still shortens life expectancy by 9 years and healthy life expectancy free of comorbidities 16 years, according to a review of HIV patients and matched controls at Kaiser Permanente facilities in California and the mid-Atlantic states during 2000-2016.
The good news is that starting antiretroviral therapy (ART) when CD4 counts are 500 cells/mm3 or higher closes the mortality gap. People who do so can expect to live into their mid-80s, the same as people without HIV, and the years they can expect to be free of diabetes and cancer is catching up to uninfected people, although the gap for other comorbidities hasn’t changed and the overall comorbidity gap remains 16 years, according to the report, which was presented at the Conference on Retroviruses & Opportunistic Infections
“We were excited about finding no difference in lifespan for people starting ART with high CD4 counts, but we were surprised by how wide the gap was for the number of comorbidity free years. Greater attention to comorbidity prevention is needed,” said study lead Julia Marcus, PhD, an infectious disease epidemiologist and assistant professor of population medicine at Harvard Medical School, Boston.
The team estimated the average number of total and comorbidity-free years of life remaining at age 21 for 39,000 people with HIV who were matched 1:10 with 387,767 uninfected adults by sex, race/ethnicity, year, and medical center.
Overall, adults with HIV could expect to live until they were 77 years old, versus 86 years for people without HIV, during 2014-2016. It’s a large improvement over the 22 year gap during 2000-2003, when the numbers were 59 versus 81 years, respectively, Dr. Marcus reported at the virtual meeting, which was scheduled to be in Boston, but held online this year because of concerns about spreading the COVID-19 virus.
But the overall comorbidity gap didn’t budge during 2000-2016. People with HIV during 2014-2016 could expect to be comorbidity free until age 36 years, versus 52 years for the general population, the same 16-year difference during 2000-2003, when the numbers were age 32 versus age 48 years.
During 2014-2016, liver disease came 24 years sooner with HIV, and chronic kidney disease 17 years, chronic lung disease 16 years, cancer 9 years, and diabetes and cancer both 8 years sooner. Early ART didn’t narrow the gap for most comorbidities. Dr. Marcus didn’t address the reasons for the differences, except to note that “smoking rates were definitely higher among people with HIV.”
The results weren’t broken down by sex, but the majority of subjects, 88%, were men. The mean age was 41 years, and about half were white, with most of the rest either black or Hispanic. Transmission was among men who have sex with men in 70% of the cases, heterosexual sex in 20%, and IV drug accounted for the rest. Almost a third of the subjects started ART with CD4 counts at or above 500 cells/mm3.
Dr. Marcus said the results are likely generalizable to most insured people with HIV, but also that comorbidity screening might be higher in the HIV population, which could have affected the results.

Physicians pessimistic despite increased COVID-19 test kits
according to a survey.
One positive finding from the physicians who participated in this survey March 19-20 was that the availability of COVID-19 test kits has more than doubled since late February.
Reported access to test kits went from 31% in the first wave of a series of surveys (Jan. 31–Feb. 4), down to 20% in the second (Feb. 26-27), and then jumped to 67% by the third wave (March 19-20), InCrowd reported March 26.
Views on several other COVID-related topics were negative among the majority of responding physicians – all of whom had or were currently treating 20 or more patients with flu-like symptoms at the time of the survey.
“Their frustrations and concerns about their ability to protect themselves while meeting upcoming patient care levels has increased significantly in the last 3 months,” Daniel S. Fitzgerald, CEO and president of InCrowd, said in a written statement.
In the third wave, 78% of respondents were “concerned for the safety of loved ones due to my exposure as a physician to COVID-19” and only 16% believed that their facility was “staffed adequately to treat the influx of patients anticipated in the next 30 days,” InCrowd said.
One primary care physician from California elaborated on the issue of safety equipment: “First, [the CDC] said we need N95 masks and other masks would not protect us. As those are running out then they said just use regular surgical masks. Now they are saying use bandannas and scarves! It’s like they don’t care about the safety of the people who will be treating the ill! We don’t want to bring it home to our families!”
“Overall, morale appears low, with few optimistic about the efficacy of public-private collaboration (21%), their own safety given current PPE [personal protective equipment] supply (13%), and the U.S.’s ability to ‘flatten the curve’ (12%),” InCrowd noted in the report.
The first two waves each had 150 respondents, but the number increased to 263 for wave 3, with similar proportions – about 50% emergency medicine or critical care specialists, 25% pediatricians, and 25% primary care physicians – in all three.

Less pain with a cancer drug to treat anal HPV, but it’s expensive
At the end of 6 months of low-dose pomalidomide (Pomalyst), more than half of men who have sex with men had partial or complete clearance of long-standing, grade 3 anal lesions from human papillomavirus, irrespective of HIV status; the number increased to almost two-thirds when they were checked at 12 months, according to a 26-subject study said in video presentation of his research during the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because of concerns about the spread of COVID-19.
“Therapy induced durable and continuous clearance of anal HSIL [high-grade squamous intraepithelial lesions]. Further study in HPV-associated premalignancy is warranted to follow up this small, single arm study,” said study lead Mark Polizzotto, MD, PhD, head of the therapeutic and vaccine research program at the Kirby Institute in Sydney.
HPV anal lesions, and subsequent HSIL and progression to anal cancer, are prevalent among men who have sex with men. The risk increases with chronic lesions and concomitant HIV infection.
Pomalidomide is potentially a less painful alternative to options such as freezing and laser ablation, and it may have a lower rate of recurrence, but it’s expensive. Copays range upward from $5,000 for a month supply, according to GoodRx. Celgene, the maker of the drug, offers financial assistance.
Pomalidomide is a derivative of thalidomide that’s approved for multiple myeloma and also has shown effect against a viral lesion associated with HIV, Kaposi sarcoma. The drug is a T-cell activator, and since T-cell activation also is key to spontaneous anal HSIL clearance, Dr. Polizzotto and team wanted to take a look to see if it could help, he said.
The men in the study were at high risk for progression to anal cancer. With a median lesion duration of more than 3 years, and at least one case out past 7 years, spontaneous clearance wasn’t in the cards. The lesions were all grade 3 HSIL, which means severe dysplasia, and more than half of the subjects had HPV genotype 16, and the rest had other risky genotypes. Ten subjects also had HIV, which also increases the risk of anal cancer.
Pomalidomide was given in back-to-back cycles for 6 months, each consisting of 2 mg orally for 3 weeks, then 1 week off, along with a thrombolytic, usually aspirin, given the black box warning of blood clots. The dose was half the 5-mg cycle for Kaposi’s.
The overall response rate – complete clearance or a partial clearance of at least a 50% on high-resolution anoscopy – was 50% at 6 months (12/24), including four complete responses (4/15, 27%) in subjects without HIV, as well as four in the HIV group (4/9, 44%).
On follow-up at month 12, “we saw something we did not expect. Strikingly, with no additional therapy in the interim, we saw a deepening of response in a number of subjects.” The overall response rate climbed to 63% (15/24), including 33% complete response in the HIV-free group (5/15) and HIV-positive group (3/9).
Some did lose their response in the interim, however, and the study team is working to figure out if it was do to a recurrence or a new infection.
A general pattern of immune activation on treatment, including increased systemic CD4+ T-cell responses to HPV during therapy, supported the investigator’s hunch of an immunologic mechanism of action, Dr. Polizzotto said.
There were four instances of grade 3 neutropenia over eight treatment cycles, and one possibly related angina attack, but other than that, adverse reactions were generally mild and self-limited, mostly to grade 1 or 2 neutropenia, constipation, fatigue, and rash, with no idiosyncratic reactions in the HIV group or loss of viral suppression, and no discontinuations because of side effects.
The men in the study were aged 40-50 years, with a median age of 54 years; all but one were white. The median lesion involved a quarter of the anal ring, but sometimes more than half.
The work was funded by the Cancer Institute of New South Wales, the Australian National Health and Medical Research Council, and Celgene. Dr. Polizzotto disclosed patents with Celgene and research funding from the company.

There were four instances of grade 3 neutropenia over eight treatment cycles, and one possibly related angina attack, but other than that, adverse reactions were generally mild and self-limited, mostly to grade 1 or 2 neutropenia, constipation, fatigue, and rash, with no idiosyncratic reactions in the HIV group or loss of viral suppression, and no discontinuations because of side effects.
The men in the study were aged 40-50 years, with a median age of 54 years; all but one were white. The median lesion involved a quarter of the anal ring, but sometimes more than half.
The work was funded by the Cancer Institute of New South Wales, the Australian National Health and Medical Research Council, and Celgene. Dr. Polizzotto disclosed patents with Celgene and research funding from the company.

Visceral fat predicts NAFLD fibrosis, progression in HIV
Increased visceral fat predicts both the presence of hepatic fibrosis in HIV patients with nonalcoholic fatty liver disease and also its progression, according to a report at the Conference on Retroviruses & Opportunistic Infections.
Among 58 people with NAFLD and well-controlled HIV, mostly men, a “striking 43% had evidence of fibrosis” on liver biopsy, a quarter with severe stage 3 fibrosis. Visceral fat content on MRI predicted fibrosis (284 cm2 among fibrotic patients vs. 212 cm2 among nonfibrotic patients, P = .005), but body mass index (BMI), waist circumference, subcutaneous fat, and hepatic fat content did not, said investigators led by Lindsay Fourman, MD, an attending physician at the Neuroendocrine & Pituitary Tumor Clinical Center at Massachusetts General Hospital, Boston.
Among 24 subjects with a second liver biopsy a year later, 38% had fibrosis progression, more than half from no fibrosis at baseline. Baseline visceral fat (306 cm2 among progressors versus 212 cm2, P = .04) again predicted progression, after adjustment for baseline BMI, hepatic fat content, and NAFLD activity score.
For every 25 cm2 rise in baseline visceral fat, the team found a 40% increased odds of fibrosis progression (P = .03). Body mass index was stable among subjects, so progression was not related to sudden weight gain. Dr. Fourman noted that people with HIV can have normal BMIs, but still significant accumulation of visceral fat.
The mean rate of progression was 0.2 stages per year. “To put this into perspective, the rate of fibrosis progression among NAFLD in the general population has been quoted to be about 0.03 stages per year.” Among HIV patients, it’s “more than sixfold higher,” she said in a video presentation of her research at the meeting, which was presented online this year. CROI organizers chose to hold a virtual meeting due to concerns about the spread of COVID-19.
Overall, visceral adiposity is “a novel clinical predictor of accelerated” progression in people with HIV. “Therapies to reduce visceral fat may be particularly effective in HIV-associated NAFLD,” she said.
The findings come from a trial of one such therapy, the growth hormone releasing hormone analogue tesamorelin (Egrifta). It’s approved for reduction of excess abdominal fat in HIV patients with lipodystrophy. Dr. Fourman and her colleagues recently reported a more than 30% reduction in liver fat, versus placebo, among HIV patients with NAFLD after a year of treatment, and a lower rate of fibrosis progression at 10.5% versus 37.5% (Lancet HIV. 2019 Dec;6[12]:e821-30).
In their follow-up study reported at the meeting, people with fibrosis at baseline also had higher NAFLD activity scores (3.6 points vs. 2.0 points; P < .0001), as well as higher ALT (41 U/L vs. 23 U/L, P = .002) and AST levels (44 U/L vs. 24 U/L; P = .0003).
Baseline BMI, liver fat content, NAFLD activity score, liver enzymes, waist circumference, CD4 count, and HIV duration, a median of 16 years in the study, did not predict progression, but activity scores, hemoglobin A1C, and C-reactive protein increased as fibrosis progressed.
“We really can’t speak from our own data” if HIV regimens might have had a role in progression. Sixty-two percent of the subjects were on integrase inhibitors, and integrase inhibitors are associated with weight gain, but their effect on visceral weight gain is unclear, plus BMIs were stable. Also, there was no difference in HIV regimens among the more than 100 people screened for the study between those with NAFDL and those without.
The subjects were 54 years old, on average. The average liver fat content at baseline was about 14%, and average baseline BMI just over 30 kg/m2. In addition to the 62% on integrase inhibitors, 40% were on nonnucleoside reverse transcriptase inhibitors, and 24% were on protease inhibitors.
