The SARS-CoV-2 variant first detected in the United Kingdom is rapidly becoming the dominant strain in several countries and is doubling every 10 days in the United States, according to new data.

The findings by Nicole L. Washington, PhD, associate director of research at the genomics company Helix, and colleagues were posted Feb. 7, 2021, on the preprint server medRxiv. The paper has not been peer-reviewed in a scientific journal.

The researchers also found that the transmission rate in the United States of the variant, labeled B.1.1.7, is 30%-40% higher than that of more common lineages.

While clinical outcomes initially were thought to be similar to those of other SARS-CoV-2 variants, early reports suggest that infection with the B.1.1.7 variant may increase death risk by about 30%. 

A coauthor of the current study, Kristian Andersen, PhD, told the New York Times , “Nothing in this paper is surprising, but people need to see it.”

Dr. Andersen, a virologist at the Scripps Research Institute in La Jolla, Calif., added that “we should probably prepare for this being the predominant lineage in most places in the United States by March.”

The study of the B.1.1.7 variant adds support for the Centers for Disease Control and Prevention prediction in January that it would dominate by March.

“Our study shows that the U.S. is on a similar trajectory as other countries where B.1.1.7 rapidly became the dominant SARS-CoV-2 variant, requiring immediate and decisive action to minimize COVID-19 morbidity and mortality,” the researchers wrote.

The authors pointed out that the B.1.1.7 variant became the dominant SARS-CoV-2 strain in the United Kingdom within a couple of months of its detection.

“Since then, the variant has been increasingly observed across many European countries, including Portugal and Ireland, which, like the U.K., observed devastating waves of COVID-19 after B.1.1.7 became dominant,” the authors wrote.
 

“Category 5” storm

The B.1.1.7 variant has likely been spreading between U.S. states since at least December, they wrote.

This news organization reported on Jan. 15 that, as of Jan. 13, the B.1.1.7 variant was seen in 76 cases across 12 U.S. states, according to an early release of the CDC’s Morbidity and Mortality Weekly Report. 

As of Feb. 7, there were 690 cases of the B.1.1.7 variant in the US in 33 states, according to the CDC.

Dr. Washington and colleagues examined more than 500,000 coronavirus test samples from cases across the United States that were tested at San Mateo, Calif.–based Helix facilities since July.

In the study, they found inconsistent prevalence of the variant across states. By the last week in January, the researchers estimated the proportion of B.1.1.7 in the U.S. population to be about 2.1% of all COVID-19 cases, though they found it made up about 2% of all COVID-19 cases in California and about 4.5% of cases in Florida. The authors acknowledged that their data is less robust outside of those two states.

Though that seems a relatively low frequency, “our estimates show that its growth rate is at least 35%-45% increased and doubling every week and a half,” the authors wrote.

“Because laboratories in the U.S. are only sequencing a small subset of SARS-CoV-2 samples, the true sequence diversity of SARS-CoV-2 in this country is still unknown,” they noted.

Michael Osterholm, PhD, MPH, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, said last week that the United States is facing a “Category 5” storm with the spread of the B.1.1.7 variant as well as the variants first identified in South Africa and Brazil.

“We are going to see something like we have not seen yet in this country,” Dr. Osterholm said recently on NBC’s Meet the Press.

The emergence of multiple inflammatory syndrome in children (MIS-C) in association with COVID-19 may be complicating the investigation and diagnosis of more common viral and bacterial infections, potentially delaying treatment and prolonging hospital stays.

Two recent articles published online in Hospital Pediatrics provide evidence of this phenomenon. The articles outlined case studies of children who underwent extensive investigation for MIS-C when in fact they had less severe and more common infections. MIS-C is a severe but rare syndrome that involves systemic hyperinflammation with fever and multisystem organ dysfunction similar to that of Kawasaki disease (KD).

In one of the articles, Matthew Molloy, MD, MPH, of the division of pediatric hospital medicine at Cincinnati Children’s Hospital Medical Center, and colleagues aptly asked: “What are we missing in our search for MIS-C?”
 

E. coli, not SARS-CoV-2

That question arose from a case involving a 3-year-old boy who had a 6-day history of fever and fatigue. Three days earlier, he had tested negative for strep antigen and COVID-19. He had a persistent, high fever, reduced appetite, and reduced urine output and was taken to the ED. On physical examination, there was no rash, skin peeling, redness of the eye or oral mucosa, congestion, rhinorrhea, cough, shortness of breath, chest pain, abdominal pain, nausea, vomiting, or diarrhea.

Urinalysis results and exam findings were suspicious for pyelonephritis. Other findings from an extensive laboratory workup raised the alarm that the boy was suffering from MIS-C as opposed to incomplete KD. After admission to hospital medicine, the cardiology, rheumatology, and infectious disease teams were called in to consult.

Repeat labs were planned for the following day before initiating therapy. On day 2, the child’s urine culture was positive for gram-negative rods, later identified as Escherichia coli. The boy was started on ceftriaxone. Left renal scarring was apparent on ultrasound. The patient’s condition resolved after 36 hours, and he was discharged home with antibiotics.
 

‘Diagnosis derailed’

Calling this a case of “diagnosis derailed,” the authors noted that, in the pre-COVID era, this child’s signs and symptoms would likely have triggered a more targeted and less costly evaluation for more common infectious and noninfectious causes, including pyelonephritis, absent any physical exam findings consistent with KD.

“However, the patient presented in the midst of the COVID-19 pandemic with growing awareness of a new clinical entity,” Dr. Molloy and colleagues wrote. “Anchored to the patient’s persistent fever, the medical team initiated an extensive, costly, and ultimately unnecessary workup to avoid missing the diagnosis of MIS-C; a not yet well-described diagnosis with potentially severe morbidity.”

Confirmation bias and diagnostic momentum likely contributed to the early focus on MIS-C rather than more common alternatives, the authors acknowledged. The addition of mildly abnormal laboratory data not typically obtained in the evaluation of fever led the team astray. “The diagnosis and definitive treatment may have been made earlier had the focus on concern for MIS-C not been present,” Dr. Molloy said in an interview.
 

Keeping value in care

The authors recognized that their initial approach to evaluating for MIS-C provided low-value care. “In our desire to not ‘miss’ MIS-C, we were performing costly evaluations that at times produced mildly abnormal, nonspecific results,” they wrote. That triggered a cascade of specialty consultations, follow-up testing, and an unwarranted diagnostic preoccupation with MIS-C.

Determining the extra price tag for the child’s workup would be complex and difficult because there is a difference in the cost to the hospital and the cost to the family, Dr. Molloy said. “However, there are potential cost savings that would be related to making a correct diagnosis in a timely manner in terms of preventing downstream effects from delayed diagnoses.”

Even as clinicians struggle with the challenging SARS-CoV-2 learning curve, Dr. Molloy and associates urged them to continue to strive for high-value care, with an unwavering focus on using only necessary resources, a stewardship the pandemic has shown to be critical.

“The COVID-19 pandemic has been an incredibly stressful time for physicians and for families,” Dr. Molloy said. “COVID-19 and related conditions like MIS-C are new, and we are learning more and more about them every week. These diagnoses are understandably on the minds of physicians and families when children present with fever.” Notwithstanding, the boy’s case underscores the need for clinicians to consider alternate diagnoses and the value of the care provided.
 

Impact of bias

Dr. Molloy’s group brings home the cognitive biases practitioners often suffer from, including anchoring and confirmation bias and diagnostic momentum, according to J. Howard Smart, MD, chief of pediatrics at Sharp Mary Birch Hospital for Women and Newborns, San Diego, and an assistant clinical professor of pediatrics at University of California, San Diego.

“But it is one thing to recognize these in retrospect and quite another to consider whether they may be happening to you yourself in real time,” he said in an interview. “It is almost as if we need to have a ‘time out,’ where we stop and ask ourselves whether there is something else that could be explaining our patient’s presentation, something that would be more common and more likely to be occurring.”

According to Dr. Smart, who was not involved in Dr. Molloy’s study, the team’s premature diagnostic focus on MIS-C was almost the inverse of what typically happens with KD. “It is usually the case that Kawasaki disease does not enter the differential diagnosis until late in the course of the fever, typically on day 5 or later, when it may have been better to think of it earlier,” he said.

In the second article, Andrea Dean, MD, of the department of pediatrics at Baylor College of Medicine and Texas Children’s Hospital, both in Houston, and colleagues outlined the cases of five patients aged 8-17 years who were hospitalized in May 2020 for suspected MIS-C. They exhibited inflammatory and other concerning indicators but were eventually discharged with a diagnosis of murine typhus.

This flea-borne infection, most commonly reported in the United States in the southeastern Gulf Coast region, Hawaii, and California, is often associated with a triad of fever, rash, and headache.

Cases have been rising in southern Texas, and Dr. Dean and colleagues postulated that school closures and social distancing may have increased exposure as a result of children spending more time outdoors or with pets. “Alternatively, parental concern for SARS-CoV-2 infection could mean children with symptoms are presenting to care and being referred or admitted to the hospital more frequently due to provider concern for MIS-C,” they wrote.
 

Cardiac involvement

The most concerning of the five cases in terms of possible MIS-C, Dr. Dean said in an interview, was that of a 12-year-old boy who had fever for 6 days in association with headache, eczematous rash, dry lips, and conjunctivitis. Laboratory tests showed a mildly elevated C-reactive protein level, hyponatremia, and thrombocytopenia, as well as sterile pyuria and mildly elevated prothrombin time. He was treated empirically with doxycycline, and his fever resolved over the next 24 hours.

An echocardiogram at initial evaluation, however, revealed mild dilation of the left anterior descending and right coronary arteries, which led to the administration of intravenous immunoglobulin and aspirin for atypical KD, in contrast to MIS-C. The authors postulated that mild cardiac involvement in disorders other than MIS-C and KD may be underrecognized.

The lesson from these cases, Dr. Dean and associates concluded, is that hospitalists must maintain a wide differential diagnosis when assessing a child with prolonged fever and evidence of systemic inflammation. The CDC stipulates that a diagnosis of MIS-C requires the absence of a plausible alternative diagnosis.

In addition to common viral, bacterial, and noninfectious disorders, a range of regional endemic rickettsial and parasitic infections must be considered as alternative diagnoses to MIS-C. “Many of these diseases cannot be reliably differentiated from MIS-C on presentation, and as community exposure to SARS-CoV-2 grows, hospitalists should be prepared to admit febrile children with evidence of systemic inflammation for brief observation periods to evaluate for MIS-C,” Dr. Dean’s group wrote. In this context, however, empiric treatment for common or even uncommon infectious diseases may avoid overdiagnosis and overtreatment of MIS-C as well as improve patient outcomes.

“We do have specific MIS-C guidelines at our institution,” Dr. Dean said, “but like all institutions, we are dealing with the broad definition of MIS-C according to the World Health Organization and the CDC, which is really the takeaway from this paper.”
 

More difficult differentiation

Both groups of authors pointed out that, as SARS-CoV-2 spreads throughout a community, a higher percentage of the population will have positive results on antibody testing, and such results will become less useful for differentiating between MIS-C and other conditions.

Despite these series’ cautionary lessons, other experts point to the critical importance of including MIS-C early on in the interest of efficient diagnosis and therapy. “In the cases cited, other pathologies were evaluated for and treated accordingly,” said Kara Gross Margolis, MD, AGAF, an associate professor of pediatrics in the division of pediatric gastroenterology, hepatology, and nutrition at Morgan Stanley Children’s Hospital,New York. “These papers stress the need for a balance that is important, and all potential diagnoses need to be considered, but MIS-C, due to its potential severe consequences, also needs to be on our differential now.”

In her view, as this new high-morbidity entity becomes more widespread during the pandemic, it will be increasingly important to keep this condition on the diagnostic radar.

Interestingly, in a converse example of diagnostic clouding, Dr. Gross Margolis’s group reported (Gastroenterology. 2020 Oct;159[4]:1571-4.e2) last year on a pediatric case series in which the presence of gastrointestinal symptoms in children with COVID-19–related MIS-C muddied the diagnosis by confusing this potentially severe syndrome with more common and less toxic gastrointestinal infections.

According to Dr. Smart, although the two reports don’t offer evidence for a particular diagnostic practice, they can inform the decision-making process. “It may be that we will have enough evidence shortly to say what the best practice is regarding diagnostic evaluation of possible MIS-C cases,” he said. “Until then, we must remember that common things occur commonly, even during a global pandemic.”

Neither of the two reports received any specific funding. The authors disclosed no relevant financial relationships.

He had a persistent, high fever, reduced appetite, and reduced urine output and was taken to the ED. On physical examination, there was no rash, skin peeling, redness of the eye or oral mucosa, congestion, rhinorrhea, cough, shortness of breath, chest pain, abdominal pain, nausea, vomiting, or diarrhea.

Urinalysis results and exam findings were suspicious for pyelonephritis. Other findings from an extensive laboratory workup raised the alarm that the boy was suffering from MIS-C as opposed to incomplete KD. After admission to hospital medicine, the cardiology, rheumatology, and infectious disease teams were called in to consult.

Repeat labs were planned for the following day before initiating therapy. On day 2, the child’s urine culture was positive for gram-negative rods, later identified as Escherichia coli. The boy was started on ceftriaxone. Left renal scarring was apparent on ultrasound. The patient’s condition resolved after 36 hours, and he was discharged home with antibiotics.
 

‘Diagnosis derailed’

Calling this a case of “diagnosis derailed,” the authors noted that, in the pre-COVID era, this child’s signs and symptoms would likely have triggered a more targeted and less costly evaluation for more common infectious and noninfectious causes, including pyelonephritis, absent any physical exam findings consistent with KD.

“However, the patient presented in the midst of the COVID-19 pandemic with growing awareness of a new clinical entity,” Dr. Molloy and colleagues wrote. “Anchored to the patient’s persistent fever, the medical team initiated an extensive, costly, and ultimately unnecessary workup to avoid missing the diagnosis of MIS-C; a not yet well-described diagnosis with potentially severe morbidity.”

Confirmation bias and diagnostic momentum likely contributed to the early focus on MIS-C rather than more common alternatives, the authors acknowledged. The addition of mildly abnormal laboratory data not typically obtained in the evaluation of fever led the team astray. “The diagnosis and definitive treatment may have been made earlier had the focus on concern for MIS-C not been present,” Dr. Molloy said in an interview.
 

Keeping value in care

The authors recognized that their initial approach to evaluating for MIS-C provided low-value care. “In our desire to not ‘miss’ MIS-C, we were performing costly evaluations that at times produced mildly abnormal, nonspecific results,” they wrote. That triggered a cascade of specialty consultations, follow-up testing, and an unwarranted diagnostic preoccupation with MIS-C.

Determining the extra price tag for the child’s workup would be complex and difficult because there is a difference in the cost to the hospital and the cost to the family, Dr. Molloy said. “However, there are potential cost savings that would be related to making a correct diagnosis in a timely manner in terms of preventing downstream effects from delayed diagnoses.”

Even as clinicians struggle with the challenging SARS-CoV-2 learning curve, Dr. Molloy and associates urged them to continue to strive for high-value care, with an unwavering focus on using only necessary resources, a stewardship the pandemic has shown to be critical.

“The COVID-19 pandemic has been an incredibly stressful time for physicians and for families,” Dr. Molloy said. “COVID-19 and related conditions like MIS-C are new, and we are learning more and more about them every week. These diagnoses are understandably on the minds of physicians and families when children present with fever.” Notwithstanding, the boy’s case underscores the need for clinicians to consider alternate diagnoses and the value of the care provided.
 

Impact of bias

Dr. Molloy’s group brings home the cognitive biases practitioners often suffer from, including anchoring and confirmation bias and diagnostic momentum, according to J. Howard Smart, MD, chief of pediatrics at Sharp Mary Birch Hospital for Women and Newborns, San Diego, and an assistant clinical professor of pediatrics at University of California, San Diego.

“But it is one thing to recognize these in retrospect and quite another to consider whether they may be happening to you yourself in real time,” he said in an interview. “It is almost as if we need to have a ‘time out,’ where we stop and ask ourselves whether there is something else that could be explaining our patient’s presentation, something that would be more common and more likely to be occurring.”

According to Dr. Smart, who was not involved in Dr. Molloy’s study, the team’s premature diagnostic focus on MIS-C was almost the inverse of what typically happens with KD. “It is usually the case that Kawasaki disease does not enter the differential diagnosis until late in the course of the fever, typically on day 5 or later, when it may have been better to think of it earlier,” he said.

In the second article, Andrea Dean, MD, of the department of pediatrics at Baylor College of Medicine and Texas Children’s Hospital, both in Houston, and colleagues outlined the cases of five patients aged 8-17 years who were hospitalized in May 2020 for suspected MIS-C. They exhibited inflammatory and other concerning indicators but were eventually discharged with a diagnosis of murine typhus.

This flea-borne infection, most commonly reported in the United States in the southeastern Gulf Coast region, Hawaii, and California, is often associated with a triad of fever, rash, and headache.

Cases have been rising in southern Texas, and Dr. Dean and colleagues postulated that school closures and social distancing may have increased exposure as a result of children spending more time outdoors or with pets. “Alternatively, parental concern for SARS-CoV-2 infection could mean children with symptoms are presenting to care and being referred or admitted to the hospital more frequently due to provider concern for MIS-C,” they wrote.
 

Cardiac involvement

The most concerning of the five cases in terms of possible MIS-C, Dr. Dean said in an interview, was that of a 12-year-old boy who had fever for 6 days in association with headache, eczematous rash, dry lips, and conjunctivitis. Laboratory tests showed a mildly elevated C-reactive protein level, hyponatremia, and thrombocytopenia, as well as sterile pyuria and mildly elevated prothrombin time. He was treated empirically with doxycycline, and his fever resolved over the next 24 hours.

An echocardiogram at initial evaluation, however, revealed mild dilation of the left anterior descending and right coronary arteries, which led to the administration of intravenous immunoglobulin and aspirin for atypical KD, in contrast to MIS-C. The authors postulated that mild cardiac involvement in disorders other than MIS-C and KD may be underrecognized.

The lesson from these cases, Dr. Dean and associates concluded, is that hospitalists must maintain a wide differential diagnosis when assessing a child with prolonged fever and evidence of systemic inflammation. The CDC stipulates that a diagnosis of MIS-C requires the absence of a plausible alternative diagnosis.

In addition to common viral, bacterial, and noninfectious disorders, a range of regional endemic rickettsial and parasitic infections must be considered as alternative diagnoses to MIS-C. “Many of these diseases cannot be reliably differentiated from MIS-C on presentation, and as community exposure to SARS-CoV-2 grows, hospitalists should be prepared to admit febrile children with evidence of systemic inflammation for brief observation periods to evaluate for MIS-C,” Dr. Dean’s group wrote. In this context, however, empiric treatment for common or even uncommon infectious diseases may avoid overdiagnosis and overtreatment of MIS-C as well as improve patient outcomes.

“We do have specific MIS-C guidelines at our institution,” Dr. Dean said, “but like all institutions, we are dealing with the broad definition of MIS-C according to the World Health Organization and the CDC, which is really the takeaway from this paper.”
 

More difficult differentiation

Both groups of authors pointed out that, as SARS-CoV-2 spreads throughout a community, a higher percentage of the population will have positive results on antibody testing, and such results will become less useful for differentiating between MIS-C and other conditions.

Despite these series’ cautionary lessons, other experts point to the critical importance of including MIS-C early on in the interest of efficient diagnosis and therapy. “In the cases cited, other pathologies were evaluated for and treated accordingly,” said Kara Gross Margolis, MD, AGAF, an associate professor of pediatrics in the division of pediatric gastroenterology, hepatology, and nutrition at Morgan Stanley Children’s Hospital,New York. “These papers stress the need for a balance that is important, and all potential diagnoses need to be considered, but MIS-C, due to its potential severe consequences, also needs to be on our differential now.”

In her view, as this new high-morbidity entity becomes more widespread during the pandemic, it will be increasingly important to keep this condition on the diagnostic radar.

Interestingly, in a converse example of diagnostic clouding, Dr. Gross Margolis’s group reported (Gastroenterology. 2020 Oct;159[4]:1571-4.e2) last year on a pediatric case series in which the presence of gastrointestinal symptoms in children with COVID-19–related MIS-C muddied the diagnosis by confusing this potentially severe syndrome with more common and less toxic gastrointestinal infections.

According to Dr. Smart, although the two reports don’t offer evidence for a particular diagnostic practice, they can inform the decision-making process. “It may be that we will have enough evidence shortly to say what the best practice is regarding diagnostic evaluation of possible MIS-C cases,” he said. “Until then, we must remember that common things occur commonly, even during a global pandemic.”

Neither of the two reports received any specific funding. The authors disclosed no relevant financial relationships.

States that implemented mask mandates in 2020 saw a decline in the growth of COVID-19 hospitalizations between March and October 2020, according to a new study published Feb. 5 in the CDC’s Morbidity and Mortality Weekly Report.

Hospitalization growth rates declined by 5.5 percentage points for adults between ages 18-64 about 3 weeks after the mandates were implemented, compared with climbing growth rates in the 4 weeks before mandates.

CDC Director Rochelle Walensky said she was pleased to see the results, but that it’s “too early” to tell whether President Joe Biden’s recent mask orders have had an effect on cases and hospitalizations in 2021.

“We’re going to be watching the mask data very carefully,” she said during a news briefing with the White House COVID-19 Response Team on Feb. 5. “I think it’s probably still a bit too early to tell, but I’m encouraged with the decrease in case rates right now.”

In another study published Feb. 5 in the Morbidity and Mortality Weekly Report, trained observers tracked mask use at six universities with mask mandates between September and November 2020. Overall, observers reported that about 92% of people wore masks correctly indoors, which varied based on the type of mask.

About 97% of people used N95 masks correctly, compared with 92% who used cloth masks, and 79% who used bandanas, scarves, or neck gaiters. Cloth masks were most common, and bandanas and scarves were least common.

The Biden administration is considering whether to send masks directly to American households to encourage people to wear them, according to NBC News. The White House COVID-19 Response Team is debating the logistics of mailing out masks, including how many to send and what the mask material would be, the news outlet reported.

Wisconsin Gov. Tony Evers reissued a new statewide mask mandate on Feb. 4, just an hour after the Republican-controlled legislature voted to repeal his previous mandate, according to The Associated Press. Gov. Evers said his priority is to keep people safe and that wearing a mask is the easiest way to do so.

“If the legislature keeps playing politics and we don’t keep wearing masks, we’re going to see more preventable deaths,” he said. “It’s going to take even longer to get our state and our economy back on track.”

Little has been known about children sick enough with COVID-19 to require intensive care because such patients are relatively few, but preliminary data analyzed from a nationwide registry indicate that they are more likely to be older, to be Black, and to have asthma.

Gastrointestinal distress is also more common in children with severe COVID-19, according to research by Sandeep Tripathi, MD. Dr. Tripathi, a pediatric intensivist and associate professor at the University of Illinois at Peoria, presented the findings on Feb. 3 at the Society for Critical Care Medicine (SCCM) 2021 Critical Care Congress.
 

Registry data gathered from 49 sites

Results from the SCCM’s VIRUS: COVID-19 Registry, which involved data from 49 sites, included 181 children admitted to an intensive care unit between February and July 2020. Those in the ICU were older than patients who did not receive care in the ICU (10 years vs. 3.67 years; P < .01) and were more likely to be Black (28.8% vs. 17.8%; P = .02).

More of the patients who required intensive care had preexisting conditions (58.2% vs. 44.3%; P = .01), the most common of which was asthma.

For both the ICU patients and the non-ICU group, the most common presenting symptom was fever.

Symptoms that were more common among children needing ICU care included nausea/vomiting (38.4% vs. 22.1%; P < .01), dyspnea (31.8% vs. 17.7%; P < .01), and abdominal pain (25.2% vs. 14.1%; P < .01).

Significantly higher proportions of ICU patients had multisystem inflammatory syndrome of childhood (MIS-C) (44.2% vs. 6.8%; P < .01) and acute kidney injury (9.34% vs. 1.7%; P < .01).

“The children who presented with MIS-C tended to be much sicker than children who present with just COVID,” Dr. Tripathi said in an interview.

In this analysis, among children in ICUs with COVID, the mortality rate was 4%, Dr. Tripathi said.

He said he hopes the information, which will be periodically published with updated data, will raise awareness of which children might be likely to experience progression to severe disease.

“The information may help physicians be more mindful of deterioration in those patients and be more aggressive in their management,” he said. When children are brought to the emergency department with the features this analysis highlights, he said, “physicians should have a low threshold for treating or admitting the patients.”

Another study that was presented on Feb. 3 in parallel with the registry study described patterns of illness among 68 children hospitalized with COVID-19 in a tertiary-care pediatric center.

In that analysis, Meghana Nadiger, MD, a critical care fellow with Nicklaus Children’s Hospital in Miami, found that all patients admitted to the pediatric ICU (n = 17) had either MIS-C or severe illness and COVID-19-related Kawasaki-like disease.

The investigators also found that the patients with serious illness were more commonly adolescents with elevated body mass index (73%). In this study, 83.8% of the hospitalized children were Hispanic. They also found that 88.8% of the children older than 2 years who had been hospitalized with COVID-19 were overweight or obese, with a BMI >25 kg/m².

Jerry Zimmerman, MD, PhD, SCCM’s immediate past president, said in an interview that he found it interesting that in the Nadiger study, “All of the children with severe illness had MIS-C as compared to adults, who typically are critically ill with severe acute respiratory distress syndrome.” Dr. Zimmerman was not involved in either study.

He said that although the high percentage of Hispanic patients in the hospitalized population may reflect the high percentage of Hispanic children in the Miami area, it may also reflect challenges of controlling the disease in the Hispanic community. Such challenges might include shortages of personal protective equipment, poorer access to health care, and difficulty in social distancing.

Dr. Zimmerman pointed out that obesity is an important risk factor for COVID-19 and that according to the Centers for Disease Control and Prevention, childhood obesity is much more common among Hispanics (25.8%) and non-Hispanic Blacks persons (22.0%) compared with non-Hispanic White persons (14.1%).

The VIRUS registry is funded in part by the Gordon and Betty Moore Foundation and Janssen Research and Development. Dr. Tripathi, Dr. Nadiger, and Dr. Zimmerman have disclosed no relevant financial relationships.

Among critically ill patients pulseless after planned withdrawal of life-sustaining therapies, cardiac activity restarted in 14% of cases, research shows.

Reassuringly, most resumption of heart activity happened in the first 1-2 minutes and most lasted 1 or 2 seconds.

“The reason we wanted to look at death determination specifically is we know that the stories persist about people coming back to life following death, and that’s not just in the public, it’s in the medical community as well,” lead author Sonny Dhanani, MD, of Children’s Hospital of Eastern Ontario, Ottawa, said in an interview.

“We thought that if we provided scientific evidence of whether this happened or not, we might dispel some myths and misunderstanding, which would hopefully promote organ donation.”

About 70% of organ donations occur after brain death, but an increasing number follow circulatory determination of death, he noted. Most protocols recommend 5 minutes of apnea and pulselessness by arterial catheter monitor before declaring death. But practices vary from 10 minutes in some European countries to 75 seconds in infant heart donors at one Colorado hospital.

Reports of patients recovering 10 minutes after pulselessness have raised concerns about the Lazarus phenomenon, or autoresuscitation, but are based in patients after cardiopulmonary resuscitation was terminated.

The present study, known as Death Prediction and Physiology after Removal of Therapy (DePParRT), enrolled patients at 20 intensive care sites in Canada, the Czech Republic, and the Netherlands, only if surrogate decision-makers agreed on withdrawal of life-sustaining measures without CPR and imminent death was anticipated.

As reported Jan. 28 in the New England Journal of Medicine, physicians observed resumption of circulation or cardiac activity prospectively in 1% of 631 patients based on bedside ECG, arterial pressure catheter monitors, palpated arterial pulse, breaths, or physical movements.

A retrospective review of data from 480 patients with complete ECG and arterial waveforms and at least 5 minutes of continuous waveform monitoring after pulselessness showed resumption of cardiac activity in 14% of patients.

The longest period of pulselessness before the heart showed signs of activity again was 4 minutes and 20 seconds. “So that was a reassuring number, because that’s within our 5-minute window that we currently use,” Dr. Dhanani said.

Importantly, “nobody woke up, nobody ended up being resuscitated, and all of these individuals died. And I think that’s going to be very helpful in this context,” he added.

In all, there were 77 cessations and resumptions in 67 of the 480 patients. The median duration of resumed cardiac activity was 3.9 seconds but, notably, ranged from 1 second to 13 minutes and 14 seconds.

“Though surprising, I think maybe not unreasonable,” observed Dr. Dhanani. “The heart is a very robust organ, and we maybe should anticipate these things happening, where at the end of life the heart may restart for minutes.”

In this situation, it’s important to wait the 13 minutes for the heart to stop again and then “wait another 5 minutes to make sure it doesn’t restart before determining death,” he said. “I think that’s where this study is going to now inform policy makers and guidelines, especially in the context of donations.”

The findings will be taken as strong support for the 5-minute window, said Robert Truog, MD, director of the Harvard Medical School Center for Bioethics and the Frances Glessner Lee Professor of Medical Ethics, Anaesthesia, and Pediatrics, Boston.

“I think it’s a safe point, I think people will refer to it, and it will be used to support the 5-minute window, and that’s probably reasonable,” he told this news organization. “Certainly, if it’s read in Europe it will cut the time from 10 minutes to 5 minutes, and that’s a good thing because 10 minutes is a very long time to wait.”

He noted that the 5-minute window provides reasonable assurance to the public and, with new technologies, permits most organs to be usable for donation after cardiac death. That said, there’s nothing magical about the number.

“In some ways I see this paper as providing interesting data but not actually providing an answer, because from the patient’s perspective and from the recipient’s perspective, waiting until the heart has made its last squeeze may not be the most relevant ethical question,” Dr. Truog said. “It may be, once we know this patient is not going to have return of cardiorespiratory function, is not going to wake up, that’s the point at which we ought to focus on organ preservation and organ retrieval, and that can be much sooner than 5 minutes.”

Dr. Dhanani and colleagues note that the generalizability of the results might be limited because patients without arterial pressure catheters were excluded, and 24% of enrolled patients could not be included in the retrospective waveform analysis owing to incomplete data.

“Our study definition of cardiac activity used an arbitrary threshold of pulse pressure (less than 5 mm Hg) that does not imply meaningful circulation,” they add. “This conservative consensus definition may have been partially responsible for the ostensibly high incidence (14%) of transient resumptions of cardiac activity identified through waveform adjudication.”

The study was supported by the Canadian Institutes for Health Research as part of the Canadian Donation and Transplantation Research Program, CHEO Research Institute, and Karel Pavlík Foundation. Dr. Dhanani has consulted for Canadian Blood Services. Dr. Truog reports no relevant conflicts of interest.

Among critically ill patients pulseless after planned withdrawal of life-sustaining therapies, cardiac activity restarted in 14% of cases, research shows.

Reassuringly, most resumption of heart activity happened in the first 1-2 minutes and most lasted 1 or 2 seconds.

“The reason we wanted to look at death determination specifically is we know that the stories persist about people coming back to life following death, and that’s not just in the public, it’s in the medical community as well,” lead author Sonny Dhanani, MD, of Children’s Hospital of Eastern Ontario, Ottawa, said in an interview.

“We thought that if we provided scientific evidence of whether this happened or not, we might dispel some myths and misunderstanding, which would hopefully promote organ donation.”

About 70% of organ donations occur after brain death, but an increasing number follow circulatory determination of death, he noted. Most protocols recommend 5 minutes of apnea and pulselessness by arterial catheter monitor before declaring death. But practices vary from 10 minutes in some European countries to 75 seconds in infant heart donors at one Colorado hospital.

Reports of patients recovering 10 minutes after pulselessness have raised concerns about the Lazarus phenomenon, or autoresuscitation, but are based in patients after cardiopulmonary resuscitation was terminated.

The present study, known as Death Prediction and Physiology after Removal of Therapy (DePParRT), enrolled patients at 20 intensive care sites in Canada, the Czech Republic, and the Netherlands, only if surrogate decision-makers agreed on withdrawal of life-sustaining measures without CPR and imminent death was anticipated.

As reported Jan. 28 in the New England Journal of Medicine, physicians observed resumption of circulation or cardiac activity prospectively in 1% of 631 patients based on bedside ECG, arterial pressure catheter monitors, palpated arterial pulse, breaths, or physical movements.

A retrospective review of data from 480 patients with complete ECG and arterial waveforms and at least 5 minutes of continuous waveform monitoring after pulselessness showed resumption of cardiac activity in 14% of patients.

The longest period of pulselessness before the heart showed signs of activity again was 4 minutes and 20 seconds. “So that was a reassuring number, because that’s within our 5-minute window that we currently use,” Dr. Dhanani said.

Importantly, “nobody woke up, nobody ended up being resuscitated, and all of these individuals died. And I think that’s going to be very helpful in this context,” he added.

In all, there were 77 cessations and resumptions in 67 of the 480 patients. The median duration of resumed cardiac activity was 3.9 seconds but, notably, ranged from 1 second to 13 minutes and 14 seconds.

“Though surprising, I think maybe not unreasonable,” observed Dr. Dhanani. “The heart is a very robust organ, and we maybe should anticipate these things happening, where at the end of life the heart may restart for minutes.”

In this situation, it’s important to wait the 13 minutes for the heart to stop again and then “wait another 5 minutes to make sure it doesn’t restart before determining death,” he said. “I think that’s where this study is going to now inform policy makers and guidelines, especially in the context of donations.”

The findings will be taken as strong support for the 5-minute window, said Robert Truog, MD, director of the Harvard Medical School Center for Bioethics and the Frances Glessner Lee Professor of Medical Ethics, Anaesthesia, and Pediatrics, Boston.

People with rheumatic and musculoskeletal diseases (RMDs) who contract the SARS-CoV-2 virus appear more likely to die from COVID-19 if their rheumatologic condition is not being well controlled at the time of their infection.

New data from the COVID-19 Global Rheumatology Alliance (GRA) physician registry reported in Annals of the Rheumatic Diseases have found that the odds of dying from COVID-19 were 87% higher in individuals recorded as having moderate to high disease activity versus those reported to be in remission or having low disease activity.

“I think this really highlights the importance of continuing to appropriately, and actively, treat our patients, and the importance of controlling their disease,” Pedro Machado, MD, PhD, said in an interview. Dr. Machado, an associate professor in rheumatology and muscle diseases at University College London and a consultant rheumatologist at several U.K. hospitals, has been involved in the GRA physician registry from the start, and sits on the GRA steering committee.

Alongside higher disease activity, several other important factors were found to be associated with increased odds of dying from COVID-19 – older age, male gender, and the presence of one or more comorbidities, such as hypertension combined with cardiovascular disease or chronic lung disease.

These demographic and disease-based factors have been linked to an increased risk for COVID-19–related hospitalization before, both in people with RMDs and in the general population, but the latest GRA physician registry data now take that a step further, and link them also to an increased risk for death, together with several other factors more specific to RMDs.
 

Logging COVID-19 rheumatologic cases

Since the start of the global pandemic, the potential effects that SARS-CoV-2 infection might have on people with RMDs in particular has concerned the rheumatology community. The main worries being that, either because of the underlying RMD itself or to its treatment, there may be immunoregulatory deficits or other risk factors that would make individuals more susceptible to not only infection but also to developing more severe COVID-19 than the general population.

These concerns led to the rapid formation of the GRA and the COVID-19 GRA physician registry in March 2020 to collect and analyze data on adults with rheumatic disease and confirmed or presumptive COVID-19. Entries into the registry are made by or under the direction of rheumatologists, and this is a voluntary process.

“This population cannot ever be entirely representative of the population of patients with rheumatic diseases,” Dr. Machado acknowledged. There will be selection and other biases that affect the reported data. That said, it’s the largest database of reported COVID-19 cases in adult rheumatology patients across the world, with more than 9,000 cases so far included from multiple registries, including those based in Europe and North and South America. Data from one of these – the French RMD cohort – have also recently been published in Annals of the Rheumatic Diseases, showing much the same findings but on a national level.

Hospitalization was the focus of a previous report because “you need large sample sizes” to look at endpoints that occur less frequently. When the first analysis was done, there were around 600 cases from 40 countries in the registry with sufficient data that could be used. Now, with a greater number of recorded cases, factors influencing the risk for death could be examined.

Death rate and risk factors found

Data on 3,729 COVID-19 cases in people with RMDs were included in the current analysis, all recorded in the first few months of the registry being open and up until July 1, 2020. In all, 390 (10.5%) of people died. While this is “clearly higher” than reported in the general population in most countries, the analysis was not designed to calculate a precise estimate.

“It should not be taken as an estimate of the overall death rate among patients with rheumatic diseases and COVID-19,” Dr. Machado and coauthors have been keen to point out.

“Age is always the biggest risk factor,” Dr. Machado explained. “There’s always a gradient: the older the patient, the worse the outcome.”

Indeed, there was a threefold increased risk for death among those aged 66-75 years versus those who were 65 years or younger (odds ratio, 3.00), and a sixfold increased risk for patients older than 75, compared with the younger age group (OR, 6.18).

Having both hypertension and cardiovascular disease was associated with an OR of 1.89, and coexisting chronic lung disease also significantly increased the chances of dying from COVID-19 (OR, 1.68).

Being of male sex was associated with a 46% increased risk for death from COVID-19 versus being of female sex.

The risk for COVID-19 death also rose with the use of corticosteroids. Compared with no steroid use, there was a 69% increased risk for with death at doses of 10 mg or more prednisolone equivalent per day.

“The finding about moderate to high doses of steroids being associated with a worse outcome is consistent with the first report; it was the same for hospitalization,” Dr. Machado observed.

The general consensus on steroid use in the COVID-19 setting is that they should be continued as needed, but at the lowest possible dose, as outlined in provisional recommendations set out by the recently renamed European Alliance of Associations for Rheumatology.

The GRA physician registry findings provide further support for this, suggesting that disease control should be optimized with disease-modifying antirheumatic drugs, ideally without increasing the dose of steroids.

Surprise over sulfasalazine risk

“Taking all medications into account – such as methotrexate, leflunomide, hydroxychloroquine, [tumor necrosis factor] blockers, interleukin-6 blockers, and [Janus kinase] inhibitors – it is quite reassuring because we did not see an association with worse outcome with those drugs overall,” Dr. Machado said.

However, treatment with rituximab (OR, 4.0), sulfasalazine (OR, 3.6), and immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, mycophenolate, or tacrolimus (OR, 2.2), were associated with higher odds of dying from COVID-19 when compared with treatment with methotrexate alone.

The findings for rituximab and immunosuppressant use were perhaps not unexpected, but the possible association between sulfasalazine and COVID-19 death was “a bit intriguing,” Dr. Machado observed. “Sulfasalazine is believed to have low immunosuppressive effect.”

This warrants further investigation, but there are likely a range of confounding factors at play. One could be that people considered to be at higher risk may have been more often prescribed sulfasalazine because it was thought to be less immunosuppressive. Another might be because people taking sulfasalazine were more likely to be smokers, and they were also not advised to protect themselves from exposure to the virus (shielding) during the first wave of the pandemic, at least not in the United Kingdom.
 

Rituximab caution and vaccination

“Rituximab is a concern,” Dr. Machado acknowledged. “It is a concern that rheumatologists are now aware of and they are addressing, but then it’s a concern for a very specific subgroup of patients.”

While rheumatologists are, and will continue to prescribe it, there will be even more careful consideration over when, in whom, and how to use it during, and possibly even after, the pandemic.

“COVID is here to stay, it will become endemic, and it’s going to be part of our lives like the flu virus is,” Dr. Machado predicted.

Then there is the issue on vaccinating people against COVID-19, should those on rituximab still receive it? The answer is a yes, but, as with other vaccinations it’s all about the timing of when the vaccination is given.

Societies such as the British Society for Rheumatology have already begun to include guidance on this, recommending one of the available COVID-19 vaccines is given at least a month before the next or first dose of rituximab is due. As rituximab is given every few months, with doses sometimes spaced as much as 9 months or even a year apart, this should not be too much of a problem, but it is “better to have the vaccine first,” Dr. Machado said.
 

Has COVID-19 care improved in RMDs?

In separate research published in The Lancet Rheumatology, April Jorge, MD, of Massachusetts General Hospital and Harvard Medical School, both in Boston, and associates found that the risks of severe COVID-19 outcomes have improved over time, although they still “remain substantial.”

Dr. Jorge and colleagues looked at temporal trends in COVID-19 outcomes in patients with RMDs over the course of the first 6 months of the pandemic in 2020, using data from a large, multicenter, electronic health record network (TriNetX).

They formed two patient cohorts – a late (diagnosed from April 20 to July 20) and an early (diagnosed from January 20 to April 20) cohort – to see if outcomes had improved and discovered lower relative risks among patients in the late cohort for hospitalization (0.67), admission to the ICU (0.56), mechanical ventilation (0.39), acute kidney injury (0.66), renal replacement (0.53), and death (0.39).

“These results are encouraging,” but it’s difficult to match these different populations of patients, Dr. Machado said. “There are always factors that you cannot match for” and were not included in the U.S. analysis.

While there are important caveats in how the analysis was performed and thus in interpreting these data, they do “suggest that one of the reasons why outcomes have improved is because we have become better at treating these patients,” Dr. Machado added.

“Our treatment has improved, and our capacity to treat the complications has improved. We understand better how the disease behaves – we know that they can have thromboembolic complications that we can manage, and we are now able to manage ventilation issues better.”

Moreover, Dr. Machado said that, not only were clinicians more aware of what they should or should not do, there were treatments that were being used routinely or in some cases based on recent clinical trial results. “I think we are indeed treating these patients better.”

The COVID-19 GRA physician registry is financially supported by the American College of Rheumatology and EULAR. Dr. Machado had no relevant conflicts of interest.

The main worries being that, either because of the underlying RMD itself or to its treatment, there may be immunoregulatory deficits or other risk factors that would make individuals more susceptible to not only infection but also to developing more severe COVID-19 than the general population.

These concerns led to the rapid formation of the GRA and the COVID-19 GRA physician registry in March 2020 to collect and analyze data on adults with rheumatic disease and confirmed or presumptive COVID-19. Entries into the registry are made by or under the direction of rheumatologists, and this is a voluntary process.

“This population cannot ever be entirely representative of the population of patients with rheumatic diseases,” Dr. Machado acknowledged. There will be selection and other biases that affect the reported data. That said, it’s the largest database of reported COVID-19 cases in adult rheumatology patients across the world, with more than 9,000 cases so far included from multiple registries, including those based in Europe and North and South America. Data from one of these – the French RMD cohort – have also recently been published in Annals of the Rheumatic Diseases, showing much the same findings but on a national level.

Hospitalization was the focus of a previous report because “you need large sample sizes” to look at endpoints that occur less frequently. When the first analysis was done, there were around 600 cases from 40 countries in the registry with sufficient data that could be used. Now, with a greater number of recorded cases, factors influencing the risk for death could be examined.

Death rate and risk factors found

Data on 3,729 COVID-19 cases in people with RMDs were included in the current analysis, all recorded in the first few months of the registry being open and up until July 1, 2020. In all, 390 (10.5%) of people died. While this is “clearly higher” than reported in the general population in most countries, the analysis was not designed to calculate a precise estimate.

“It should not be taken as an estimate of the overall death rate among patients with rheumatic diseases and COVID-19,” Dr. Machado and coauthors have been keen to point out.

“Age is always the biggest risk factor,” Dr. Machado explained. “There’s always a gradient: the older the patient, the worse the outcome.”

Indeed, there was a threefold increased risk for death among those aged 66-75 years versus those who were 65 years or younger (odds ratio, 3.00), and a sixfold increased risk for patients older than 75, compared with the younger age group (OR, 6.18).

Having both hypertension and cardiovascular disease was associated with an OR of 1.89, and coexisting chronic lung disease also significantly increased the chances of dying from COVID-19 (OR, 1.68).

Being of male sex was associated with a 46% increased risk for death from COVID-19 versus being of female sex.

The risk for COVID-19 death also rose with the use of corticosteroids. Compared with no steroid use, there was a 69% increased risk for with death at doses of 10 mg or more prednisolone equivalent per day.

“The finding about moderate to high doses of steroids being associated with a worse outcome is consistent with the first report; it was the same for hospitalization,” Dr. Machado observed.

The general consensus on steroid use in the COVID-19 setting is that they should be continued as needed, but at the lowest possible dose, as outlined in provisional recommendations set out by the recently renamed European Alliance of Associations for Rheumatology.

The GRA physician registry findings provide further support for this, suggesting that disease control should be optimized with disease-modifying antirheumatic drugs, ideally without increasing the dose of steroids.

Surprise over sulfasalazine risk

“Taking all medications into account – such as methotrexate, leflunomide, hydroxychloroquine, [tumor necrosis factor] blockers, interleukin-6 blockers, and [Janus kinase] inhibitors – it is quite reassuring because we did not see an association with worse outcome with those drugs overall,” Dr. Machado said.

However, treatment with rituximab (OR, 4.0), sulfasalazine (OR, 3.6), and immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, mycophenolate, or tacrolimus (OR, 2.2), were associated with higher odds of dying from COVID-19 when compared with treatment with methotrexate alone.

The findings for rituximab and immunosuppressant use were perhaps not unexpected, but the possible association between sulfasalazine and COVID-19 death was “a bit intriguing,” Dr. Machado observed. “Sulfasalazine is believed to have low immunosuppressive effect.”

This warrants further investigation, but there are likely a range of confounding factors at play. One could be that people considered to be at higher risk may have been more often prescribed sulfasalazine because it was thought to be less immunosuppressive. Another might be because people taking sulfasalazine were more likely to be smokers, and they were also not advised to protect themselves from exposure to the virus (shielding) during the first wave of the pandemic, at least not in the United Kingdom.
 

Rituximab caution and vaccination

“Rituximab is a concern,” Dr. Machado acknowledged. “It is a concern that rheumatologists are now aware of and they are addressing, but then it’s a concern for a very specific subgroup of patients.”

While rheumatologists are, and will continue to prescribe it, there will be even more careful consideration over when, in whom, and how to use it during, and possibly even after, the pandemic.

“COVID is here to stay, it will become endemic, and it’s going to be part of our lives like the flu virus is,” Dr. Machado predicted.

Then there is the issue on vaccinating people against COVID-19, should those on rituximab still receive it? The answer is a yes, but, as with other vaccinations it’s all about the timing of when the vaccination is given.

Societies such as the British Society for Rheumatology have already begun to include guidance on this, recommending one of the available COVID-19 vaccines is given at least a month before the next or first dose of rituximab is due. As rituximab is given every few months, with doses sometimes spaced as much as 9 months or even a year apart, this should not be too much of a problem, but it is “better to have the vaccine first,” Dr. Machado said.
 

Has COVID-19 care improved in RMDs?

In separate research published in The Lancet Rheumatology, April Jorge, MD, of Massachusetts General Hospital and Harvard Medical School, both in Boston, and associates found that the risks of severe COVID-19 outcomes have improved over time, although they still “remain substantial.”

Dr. Jorge and colleagues looked at temporal trends in COVID-19 outcomes in patients with RMDs over the course of the first 6 months of the pandemic in 2020, using data from a large, multicenter, electronic health record network (TriNetX).

They formed two patient cohorts – a late (diagnosed from April 20 to July 20) and an early (diagnosed from January 20 to April 20) cohort – to see if outcomes had improved and discovered lower relative risks among patients in the late cohort for hospitalization (0.67), admission to the ICU (0.56), mechanical ventilation (0.39), acute kidney injury (0.66), renal replacement (0.53), and death (0.39).

“These results are encouraging,” but it’s difficult to match these different populations of patients, Dr. Machado said. “There are always factors that you cannot match for” and were not included in the U.S. analysis.

While there are important caveats in how the analysis was performed and thus in interpreting these data, they do “suggest that one of the reasons why outcomes have improved is because we have become better at treating these patients,” Dr. Machado added.

“Our treatment has improved, and our capacity to treat the complications has improved. We understand better how the disease behaves – we know that they can have thromboembolic complications that we can manage, and we are now able to manage ventilation issues better.”

Moreover, Dr. Machado said that, not only were clinicians more aware of what they should or should not do, there were treatments that were being used routinely or in some cases based on recent clinical trial results. “I think we are indeed treating these patients better.”

The COVID-19 GRA physician registry is financially supported by the American College of Rheumatology and EULAR. Dr. Machado had no relevant conflicts of interest.

COVID-19 cases are continuing to fall in the United States, according to the New York Times tracker, though the number of deaths from the disease again neared 4,000 on Feb. 3.

The United States has averaged 141,146 cases a day in the past week, down 30% from the average 2 weeks ago. For the first time since November 2020, the country is averaging fewer than 150,000 cases a day, according to the tracker.

However, Rochelle Walensky, MD, MPH, director of the Centers for Disease Control and Prevention, warned that new COVID-19 variants popping up widely could threaten that progress.

“Although we have seen declines in cases and admissions and a recent slowing of deaths, cases remain extraordinarily high, still twice as high as the peak number of cases over the summer. And the continued proliferation of variants, variants that likely have increased transmissibility, that spread more easily, threatens to reverse these recent trends.

“Based on contact tracing of recent variant cases, not wearing masks and participating in in-person social gatherings have contributed to the variants’ spread,” she said at a White House COVID-19 briefing on Feb. 3, 2021.

The number of cases worldwide neared 104 million on Feb. 3 and the U.S. numbers made up 26.4 million of that total.

As of Feb. 4, COVID-19 had killed at least 454,000 people and infected about 26.6 million in the United States since January 2020, according to the Johns Hopkins University tracker.

The Johns Hopkins tracker found that, per capita, North Dakota, South Dakota, and Rhode Island have reported the most cases while New Jersey and New York have recorded the most deaths.

According to the COVID tracking project, hospitalizations for COVID-19 nationwide were down to 91,440 on Feb. 3.

The tracking report noted, “compared to last week, the number of people currently hospitalized with COVID-19 is down by 10% or more in 38 states.”

Even in hard-hit Los Angeles County, infections and case numbers are on the decline, according to the Los Angeles Times. However, officials, warn the numbers remain well above presurge levels. Over the past week, 201 city residents have died every day.

Reuters also reports that Anthony S. Fauci, MD, the government’s top infectious disease expert, said despite some good news in the numbers, Americans should continue to follow social distancing guidelines. He added that double-masking may add protection.

The Food and Drug Administration has alerted the public to an increased risk of serious heart-related problems and cancer risk associated with the Janus kinase inhibitor tofacitinib (Xeljanz, Xeljanz XR), based on early results from a safety clinical trial comparing tofacitinib and tumor necrosis factor inhibitors in patients with rheumatoid arthritis (RA).

The FDA is awaiting further results from the trial, but in a safety communication issued on Feb. 4, the agency advised patients not to discontinue tofacitinib without consulting their health care providers and advised health care professionals to weigh the risks and benefits when prescribing the drug and continue to follow the current prescribing information.

Tofacitinib was approved for treatment of RA in 2012 at a 5-mg dose. After this approval, the FDA required drug manufacturer Pfizer to conduct a safety clinical trial that included the 5-mg twice-daily dose and a 10-mg twice-daily dose that is currently approved only for ulcerative colitis. In addition to RA and ulcerative colitis, tofacitinib is approved for adults with active psoriatic arthritis and patients aged 2 years or older with active polyarticular course juvenile idiopathic arthritis.

Pfizer announced partial results of the study, known as the ORAL Surveillance trial, in a press release on Jan. 27. The randomized trial included 4,362 RA patients aged 50 years and older who received either 5-mg or 10-mg doses of tofacitinib or a TNF inhibitor (adalimumab or etanercept).

The full results have yet to be released, but based on data from approximately 10,000 person-years for the combined tofacitinib groups and approximately 5,000 person-years for the TNF inhibitor group, the rate of major cardiovascular adverse events was significantly higher in the combined tofacitinib group, compared with the TNF inhibitor group (0.98 vs. 0.73 per 100 person-years; hazard ratio, 1.33). In addition, the rate of adjudicated malignancies was significantly higher in the tofacitinib group, compared with the TNF inhibitor group (1.13 vs. 0.77 per 100 person-years; HR, 1.48).

In February 2019, the FDA issued a warning stating an increased risk of pulmonary embolism and death associated with the 10-mg twice-daily dose of tofacitinib, following interims results from the safety study.

In July 2019, the FDA added a boxed warning to tofacitinib advising of the increased risk for pulmonary embolism and death associated with the 10-mg twice-daily dose.

The FDA encouraged health care professionals and patients to report any side effects from tofacitinib or other medications through the FDA MedWatch program online or by phone at 1-800-332-1088.

Until nuances revealed, no change in practice

The preliminary study findings contain some nuances that are a bit complicated from a statistical standpoint, according to Daniel Furst, MD, professor emeritus of medicine at the University of California, Los Angeles; adjunct professor at the University of Washington, Seattle; and research professor at the University of Florence (Italy).

Many women with hidradenitis suppurativa have pregnancy-related concerns that go unaddressed by their doctors, according to a study that surveyed 59 women with HS.

Previous studies have shown the potential for adverse pregnancy outcomes associated with inflammatory conditions such as systemic vasculitis and lupus, but such data on HS and pregnancy are limited, which makes patient counseling a challenge, Ademide A. Adelekun, MD, of the University of Pennsylvania, Philadelphia, and colleagues wrote.

In a research letter published in JAMA Dermatology, they reported their findings from an email survey of female patients at two academic dermatology departments. A total of 59 women responded to the survey; their average age was 32 years, the majority (76%) had Hurley stage II disease, and 29 (49%) reported having ever been pregnant.

Two of the 29 women (7%) were pregnant at the time of the study survey; 20 of the other 27 pregnant women (74%) said they had full-term births, 4 (15%) reported miscarriages, and 3 (11%) had undergone an abortion.

A total of five patients (9%) reported difficulty getting pregnant after 1 year, and seven (12%) reported undergoing fertility treatments.

Nearly three-quarters of the women (73%) reported that HS had a negative impact on their sexual health, and 54% said they wished their doctors provided more counseling on HS and pregnancy.

A total of 14 patients (24%) said they believed HS affected their ability to become pregnant because of either decreased sexual activity or decreased fertility caused by HS medications, and nearly half (49%) said they believed that discontinuing all HS medications during pregnancy was necessary for safety reasons.

Patients also expressed concern about the possible heritability of HS: 80% said that physicians had not counseled them about HS heritability and 68% expressed concern that their child would have HS.

In addition, 83% said they had not received information about the potential impact of HS on pregnancy, and 22%, or 13 women, were concerned that childbirth would be more difficult; 11 of these 13 women (85%) had HS that affected the vulva and groin, and 4 of the 8 women who reported concerns about difficulty breastfeeding had HS that involved the breast.

Of the 59 patients surveyed, 12 (20%) said they believed HS poses risks to the child, including through transmission of HS in 8 (67%) or through an infection during a vaginal delivery in 7 women (58%).

The prevalence of HS patients’ concerns about pregnancy “may have unfavorable implications for family planning and mental health and may play a role in the inadequate treatment of HS in patients who are pregnant or planning to become pregnant,” the authors noted. “Family planning and prenatal counseling are particularly critical for those with HS given that clinicians weigh the risks of medication use against the benefits of disease control, which is associated with improved pregnancy outcomes for those with inflammatory conditions.”

The study findings were limited by several factors including “recall bias, low response rate, use of a nonvalidated survey, and generalizability to nonacademic settings,” the researchers noted. However, the results emphasize the often-underrecognized concerns of women with HS and the need for improvements in pregnancy-related counseling and systematic evaluation of outcomes.

The researchers had no financial conflicts to disclose. This study was funded by a FOCUS Medical Student Fellowship in Women’s Health grant.

The prevalence of HS patients’ concerns about pregnancy “may have unfavorable implications for family planning and mental health and may play a role in the inadequate treatment of HS in patients who are pregnant or planning to become pregnant,” the authors noted. “Family planning and prenatal counseling are particularly critical for those with HS given that clinicians weigh the risks of medication use against the benefits of disease control, which is associated with improved pregnancy outcomes for those with inflammatory conditions.”

The study findings were limited by several factors including “recall bias, low response rate, use of a nonvalidated survey, and generalizability to nonacademic settings,” the researchers noted. However, the results emphasize the often-underrecognized concerns of women with HS and the need for improvements in pregnancy-related counseling and systematic evaluation of outcomes.

The researchers had no financial conflicts to disclose. This study was funded by a FOCUS Medical Student Fellowship in Women’s Health grant.

The gout drug colchicine appears to lower the severity of COVID-19, a small new Brazilian study finds, adding to evidence that the familiar medication holds promise as a treatment for hospitalized patients.

Patients who received colchicine in this randomized, double-blinded, placebo-controlled clinical trial presented better evolution in terms of the need for supplemental oxygen and the length of hospitalisation. ... Colchicine was safe and well tolerated,” the study authors wrote in RMD Open. However, deaths were rare in the trial, they added, and it is impossible to “evaluate the capacity of colchicine to avoid admission to ICU and reduce mortality.”

The oral anti-inflammatory colchicine, widely used as treatment in rheumatic disease, was first approved in the United States 60 years ago. Researchers began to explore its potential as a COVID-19 treatment in the early months of the pandemic.

On Jan. 25, an international team of researchers reported in a press release – but not yet a published paper – that the drug seemed to reduce hospitalizations, mechanical ventilation, and deaths in the ColCORONA trial. Earlier, a much-smaller, randomized, open-label, Greek trial linked the drug to reduced time to clinical deterioration and hospital stay.

The Brazilian authors of the new study, led by Maria Isabel Lopes of the University of São Paulo’s Ribeirão Preto Medical School, randomly assigned 75 hospitalized patients with moderate to severe COVID-19 to colchicine or placebo. A total of 72 subjects completed the April-August 2020 trial: 36 received colchicine (typically 0.5 mg three times for 5 days, then 0.5 mg twice daily for 5 days; doses were adjusted in low-weight patients and those with chronic kidney disease). The other 36 received the placebo.

(In the United States, 0.6-mg tablets of generic colchicine cost as little as $1.90 each with free coupons, according to goodrx.com.)

The median age in the groups was similar (55 years); and the placebo group had more women (61% vs. 47% in the colchicine group, P = .34). All 72 patients received the same COVID-19 treatment at the time of the trial: azithromycin, hydroxychloroquine, and unfractionated heparin. Most patients, about two-thirds in both groups, also received methylprednisolone because they needed higher amounts of supplemental oxygen.

Patients in the colchicine group needed supplemental oxygen for less time: Their median time of need was 4.0 days (interquartile range [IQR], 2.0-6.0) vs. 6.5 days (IQR, 4.0-9.0) for the placebo group (P < .001). The median time for hospitalization was also lower at 7.0 days (IQR, 5.0–9.0) for the colchicine group vs. 9.0 (IQR, 7.0–12.0) for the placebo group (log rank test, 10.6; P = .001).

The researchers also reported the percentage of patients who needed supplemental oxygen at day 2 as 67% with colchicine vs. 86% with placebo, and at day 7 as 9% vs. 42% (log rank test, 10.6; P = .001). Two patients in the placebo group died, both from ventilator-associated pneumonia.

As for side effects, new or worsened diarrhea was reported more often in the colchicine group (17% vs. 6% with placebo), but the difference was not statistically significant (P = .26), and diarrhea was controlled via medication.

The researchers reported that limitations include the exclusion criteria and their inability to link colchicine to rates of ICU admissions and death.

The drug appears to help patients with COVID-19, the study authors wrote, by “inhibiting inflammasome, reducing neutrophil migration and activation, or preventing endothelial damage.”

A “well-conceived and well-designed” study

In an interview, NYU Langone Health rheumatologist Michael H. Pillinger, MD – an investigator with the ColCORONA trial – praised the Brazilian study. It “appears well-conceived and well-designed, and was enrolled at a rate that was greater than the sample size that was estimated to be needed based on power analysis,” he said.

The Brazilian study is small, he noted. (In contrast, the ColCORONA trial had 4,488 outpatient participants.) “This study differs from ColCORONA in several ways – the most important being that it is a study of inpatients with moderate to severe COVID (really mostly moderate),” he added. “ColCORONA is looking at a target audience that is much larger – outpatients with mild to moderate COVID with risk factors for hospitalization. Both questions are really important and certainly not mutually exclusive, since our care remains inadequate in both venues. This study also adds value in that several other studies have been conducted in hospital patients with enrollment criteria relatively similar to this one, and all showed benefit, but those were open-label or retrospective, and this is blinded and placebo-controlled.”
 

Using colchicine in patients with COVID-19

Should physicians turn to colchicine in patients with COVID-19? “I would rather that it still be used in the context of research until formal recommendations can be made by bodies like the NIH and CDC,” Dr. Pillinger said. “But certainly, there may be times when physicians feel compelled to treat patients off label.”

He cautioned, however, that colchicine should never be used with some other drugs. Its interaction with the antibiotic clarithromycin can be fatal, he noted. And, he said, the drug must be monitored in general since it can cause rare, severe problems.

“Overall, colchicine probably works on the overabundant inflammatory response to COVID, and it may be that it can be combined with other drugs that affect viral replication or promote immunity – e.g. vaccines,” Dr. Pillinger said. “So far, it seems as if there is no safety problem with combining colchicine with other approaches, but this has not been studied in a rigorous manner.”

Moving forward, he said, the drug’s very low price outside of the United States “could provide resource-poor countries with a way to help keep patients out of precious hospital beds – or help them go home sooner once admitted.” For now, however, “we need a large-scale inpatient study, and one is currently going on in Great Britain. We also need validation of the outpatient ColCORONA study, and studies to look at whether colchicine can work in conjunction with other strategies.”

The study was funded by grants from the São Paulo Research Foundation, Brazilian National Council for Scientific and Technological Development, and CAPES Foundation. No disclosures are reported. Dr. Pillinger reports serving as an investigator for the ColCORONA trial and receiving a unrelated investigator-initiated grant from Hikma, a colchicine manufacturer.
