Worry over family, friends the main driver of COVID-19 stress
Individuals are more worried about family members becoming ill with COVID-19 or about unknowingly transmitting the disease to family members than they are about contracting it themselves, results of a new survey show.
Investigators surveyed over 3,000 adults, using an online questionnaire. Of the respondents, about 20% were health care workers, and most were living in locations with active stay-at-home orders at the time of the survey.
Close to half of participants were worried about family members contracting the virus, one third were worried about unknowingly infecting others, and 20% were worried about contracting the virus themselves.
“We were a little surprised to see that people were more concerned about others than about themselves, specifically worrying about whether a family member would contract COVID-19 and whether they might unintentionally infect others,” lead author Ran Barzilay, MD, PhD, child and adolescent psychiatrist at the Children’s Hospital of Philadelphia (CHOP), told Medscape Medical News.
The study was published online August 20 in Translational Psychiatry.
Interactive platform
“The pandemic has provided a unique opportunity to study resilience in healthcare professionals and others,” said Barzilay, assistant professor at the Lifespan Brain Institute, a collaboration between CHOP and the University of Pennsylvania, under the directorship of Raquel Gur, MD, PhD.
“After the pandemic broke out in March, we launched a website in early April where we surveyed people for levels of resilience, mental health, and well-being during the outbreak,” he added.
Survey participants then shared it with their contacts.
“To date, over 7000 people have completed it – mostly from the US but also from Israel,” Barzilay said.
The survey was anonymous, but participants could choose to have follow-up contact. The survey included an interactive 21-item resilience questionnaire and an assessment of COVID-19-related items related to worries concerning the following: contracting, dying from, or currently having the illness; having a family member contract the illness; unknowingly infecting others; and experiencing significant financial burden.
A total of 1350 participants took a second survey on anxiety and depression that utilized the Generalized Anxiety Disorder–7 and the Patient Health Questionnaire–2.
“What makes the survey unique is that it’s not just a means of collecting data but also an interactive platform that gives participants immediate personalized feedback, based on their responses to the resilience and well-being surveys, with practical tips and recommendations for stress management and ways of boosting resilience,” Barzilay said.
Tend and befriend
Ten days into the survey, data were available on 3,042 participants (64% women, 54% with advanced education, 20.5% health care providers), who ranged in age from 18 to 70 years (mean [SD], 38.9 [11.9] years).
After accounting for covariates, the researchers found that participants reported more distress about family members contracting COVID-19 and about unknowingly infecting others than about getting COVID-19 themselves (48.5% and 36% vs. 19.9%, respectively; P < .0005).
Increased COVID-19-related worries were associated with 22% higher anxiety and 16.1% higher depression scores; women had higher scores than men on both.
Each 1-SD increase in the composite score of COVID-19 worries was associated with over twice the increased probability of generalized anxiety and depression (odds ratio, 2.23; 95% confidence interval, 1.88-2.65; and OR, 1.67; 95% CI, 1.41-1.98, respectively; for both, P < .001).
On the other hand, for every 1-SD increase in the resilience score, there was a 64.9% decrease in the possibility of screening positive for generalized anxiety disorder and a 69.3% decrease in the possibility of screening positive for depression (for both, P < .0001).
Compared to participants from Israel, US participants were “more stressed” about contracting, dying from, and currently having COVID-19 themselves. Overall, Israeli participants scored higher than US participants on the resilience scale.
Rates of anxiety and depression did not differ significantly between healthcare providers and others. Health care providers worried more about contracting COVID-19 themselves and worried less about finances after COVID-19.
The authors propose that survey participants were more worried about others than about themselves because of “prosocial behavior under stress” and “tend-and-befriend,” whereby, “in response to threat, humans tend to protect their close ones (tending) and seek out their social group for mutual defense (befriending).”
This type of altruistic behavior has been “described in acute situations throughout history” and has been “linked to mechanisms of resilience for overcoming adversity,” the authors indicate.
Demographic biases
Commenting on the findings for Medscape Medical News, Golnaz Tabibnia, PhD, a neuroscientist at the University of California, Irvine, who was not involved in the research, suggested that although higher resilience scores were associated with lower COVID-related worries, it is possible, “as the authors suggest, that having more resilience resources makes you less worried, but the causality could go the other direction as well, and less worry/rumination may lead to more resilience.”
Also commenting on the study for Medscape Medical News, Christiaan Vinkers, MD, PhD, a psychiatrist at the Amsterdam University Medical Center, Amsterdam, the Netherlands, said it was noteworthy that healthcare providers reported similar levels of mood and anxiety symptoms, compared to others.
“This is encouraging, as it suggests adequate resilience levels in professionals who work in the front lines of the COVID-19 pandemic,” he said.
Resilience occurs not only at the individual level but also at the community level, which may help explain the striking differences in COVID-19-related worries and anxiety between participants from the United States and Israel, Vinkers added.
E. Alison Holman, PhD, professor, Sue and Bill Gross School of Nursing, University of California, Irvine, noted that respondents were predominantly white, female, and had relatively high incomes, “suggesting strong demographic biases in those who chose to participate.”
Holman, who was not involved with the study, told Medscape Medical News that the “findings do not address the real impact of COVID-19 on the hardest-hit communities in America – poor, Black, and Latinx communities, where a large proportion of essential workers live.”
Barzilay acknowledged that, “unfortunately, because of the way the study was circulated, it did not reach minorities, which is one of the things we want to improve.”
The study is ongoing and has been translated into Spanish, French, and Hebrew. The team plans to collect data on diverse populations.
The study was supported by grants from the National Institute of Mental Health, the Lifespan Brain Institute of Children’s Hospital of Philadelphia, Penn Medicine, the University of Pennsylvania, and in part by the Zuckerman STEM Leadership Program. Barzilay serves on the scientific board and reports stock ownership in Taliaz Health. The other authors, Golnaz, Vinkers, and Holman have disclosed no relevant financial relationships.

The earlier the better for colchicine post-MI: COLCOT
The earlier the anti-inflammatory drug colchicine is initiated after a myocardial infarction (MI) the greater the benefit, a new COLCOT analysis suggests.
The parent trial was conducted in patients with a recent MI because of the intense inflammation present at that time, and added colchicine 0.5 mg daily to standard care within 30 days following MI.
As previously reported, colchicine significantly reduced the risk of the primary end point – a composite of cardiovascular (CV) death, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina requiring revascularization – by 23% compared with placebo.
This new analysis shows the risk was reduced by 48% in patients receiving colchicine within 3 days of an MI (4.3% vs. 8.3%; adjusted hazard ratio, 0.52; 95% confidence interval, 0.32-0.84, P = .007).
Risk of a secondary efficacy end point – CV death, resuscitated cardiac arrest, MI, or stroke – was reduced by 45% over an average follow up of 22.7 months (3.3% vs 6.1%; adjusted HR, 0.55; 95% CI, 0.32-0.95, P = .031).
“We believe that our results support an early, in-hospital initiation of adjunctive colchicine for post-MI prevention,” Nadia Bouabdallaoui, MD, Montreal Heart Institute, Quebec, Canada, said during an online session devoted to colchicine at the European Society of Cardiology Congress 2020.
Session moderator Massimo Imazio, MD, professor of cardiology at the University of Turin, Italy, said the improved outcomes suggest that earlier treatment is better – a finding that parallels his own experience using colchicine in patients with pericarditis.
“This substudy is very important because this is probably also the year in cardiovascular applications [that] early use of the drug could improve outcomes,” he said.
Positive data have been accumulating for colchicine from COLCOT, LoDoCo, and, most recently, the LoDoCo2 trial, even as another anti-inflammatory drug, methotrexate, flamed out as secondary prevention in the CIRT trial.
The new COLCOT substudy included 4,661 of the 4,745 original patients and examined treatment initiation using three strata: within 0-3 days (n = 1,193), 4-7 days (n = 720), and 8-30 days (n = 2,748). Patients who received treatment within 3 days were slightly younger, more likely to be smokers, and to have a shorter time from MI to randomization (2.1 days vs 5.1 days vs. 20.8 days, respectively).
In the subset receiving treatment within 3 days, those assigned to colchicine had the same number of cardiac deaths as those given placebo (2 vs. 2) but fewer resuscitated cardiac arrests (1 vs. 3), MIs (17 vs. 29), strokes (1 vs. 5), and urgent hospitalizations for angina requiring revascularization (6 vs. 17).
“A larger trial might have allowed for a better assessment of individual endpoints and subgroups,” observed Bouabdallaoui.
Although there is growing support for colchicine, experts caution that the drug many not be for everyone. In COLCOT, 1 in 10 patients were unable to tolerate the drug, largely because of gastrointestinal (GI) issues.
Pharmacogenomics substudy
A second COLCOT substudy aimed to identify genetic markers predictive of colchicine response and to gain insights into the mechanisms behind this response. It included 767 patients treated with colchicine and another 755 treated with placebo – or about one-third the patients in the original trial.
A genome-wide association study did not find a significant association for the primary CV endpoint, although a prespecified subgroup analysis in men identified an interesting region on chromosome 9 (variant: rs10811106), which just missed reaching genomewide significance, said Marie-Pierre Dubé, PhD, director of the Université de Montréal Beaulieu-Saucier Pharmacogenomics Centre at the Montreal Heart Institute.
In addition, the genomewide analysis found two significant regions for GI events: one on chromosome 6 (variant: rs6916345) and one on chromosome 10 (variant: rs74795203).
For each of the identified regions, the researchers then tested the effect of the allele in the placebo group and the interaction between the genetic variant and treatment with colchicine. For the chromosome 9 region in males, there was no effect in the placebo group and a significant interaction in the colchicine group.
For the significant GI event findings, there was a small effect for the chromosome 6 region in the placebo group and a very significant interaction with colchicine, Dubé said. Similarly, there was no effect for the chromosome 10 region in the placebo group and a significant interaction with colchicine.
Additional analyses in stratified patient populations showed that males with the protective allele (CC) for the chromosome 9 region represented 83% of the population. The primary CV endpoint occurred in 3.2% of these men treated with colchicine and 6.3% treated with placebo (HR, 0.46; 95% CI, 0.24 - 0.86).
For the gastrointestinal events, 25% of patients carried the risk allele (AA) for the chromosome 6 region and 36.9% of these had GI events when treated with colchicine versus 18.6% when treated with placebo (HR, 2.42; 95% CI, 1.57-3.72).
Similarly, 13% of individuals carried one or two copies of the risk allele (AG+GG) for the chromosome 10 region and the risk of GI events in these was nearly four times higher with colchicine (47.1% vs. 18.9%; HR, 3.98; 95% CI 2.24-7.07).
Functional genomic analyses of the identified regions were also performed and showed that the chromosome 9 locus overlaps with the SAXO1 gene, a stabilizer of axonemal microtubules 1.
“The leading variant at this locus (rs10811106 C allele) correlated with the expression of the HAUS6 gene, which is involved in microtubule generation from existing microtubules, and may interact with the effect of colchicine, which is known to inhibit microtubule formation,” observed Dubé.
Also, the chromosome 6 locus associated with gastrointestinal events was colocalizing with the Crohn’s disease locus, adding further support for this region.
“The results support potential personalized approaches to inflammation reduction for cardiovascular prevention,” Dubé said.
This is a post hoc subgroup analysis, however, and replication is necessary, ideally in prospective randomized trials, she noted.
The substudy is important because it provides further insights into the link between colchicine and microtubule polymerization, affecting the activation of the inflammasome, session moderator Imazio said.
“Second, it is important because pharmacogenomics can help us to better understand the optimal responder to colchicine and colchicine resistance,” he said. “So it can be useful for personalized medicine, leading to the proper use of the drug for the proper patient.”
COLCOT was supported by the government of Quebec, the Canadian Institutes of Health Research, and philanthropic foundations. Bouabdallaoui has disclosed no relevant financial relationships. Dubé reported grants from the government of Quebec; personal fees from DalCor and GlaxoSmithKline; research support from AstraZeneca, Pfizer, Servier, Sanofi; and minor equity interest in DalCor. Dubé is also coauthor of patents on pharmacogenomics-guided CETP inhibition, and pharmacogenomics markers of response to colchicine.

“The results support potential personalized approaches to inflammation reduction for cardiovascular prevention,” Dubé said.
This is a post hoc subgroup analysis, however, and replication is necessary, ideally in prospective randomized trials, she noted.
The substudy is important because it provides further insights into the link between colchicine and microtubule polymerization, affecting the activation of the inflammasome, session moderator Imazio said.
“Second, it is important because pharmacogenomics can help us to better understand the optimal responder to colchicine and colchicine resistance,” he said. “So it can be useful for personalized medicine, leading to the proper use of the drug for the proper patient.”

The earlier the anti-inflammatory drug colchicine is initiated after a myocardial infarction (MI) the greater the benefit, a new COLCOT analysis suggests.
The parent trial was conducted in patients with a recent MI because of the intense inflammation present at that time, and added colchicine 0.5 mg daily to standard care within 30 days following MI.
As previously reported, colchicine significantly reduced the risk of the primary end point – a composite of cardiovascular (CV) death, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina requiring revascularization – by 23% compared with placebo.
This new analysis shows the risk was reduced by 48% in patients receiving colchicine within 3 days of an MI (4.3% vs. 8.3%; adjusted hazard ratio, 0.52; 95% confidence interval, 0.32-0.84, P = .007).
Risk of a secondary efficacy end point – CV death, resuscitated cardiac arrest, MI, or stroke – was reduced by 45% over an average follow up of 22.7 months (3.3% vs 6.1%; adjusted HR, 0.55; 95% CI, 0.32-0.95, P = .031).
“We believe that our results support an early, in-hospital initiation of adjunctive colchicine for post-MI prevention,” Nadia Bouabdallaoui, MD, Montreal Heart Institute, Quebec, Canada, said during an online session devoted to colchicine at the European Society of Cardiology Congress 2020.
Session moderator Massimo Imazio, MD, professor of cardiology at the University of Turin, Italy, said the improved outcomes suggest that earlier treatment is better – a finding that parallels his own experience using colchicine in patients with pericarditis.
“This substudy is very important because this is probably also the year in cardiovascular applications [that] early use of the drug could improve outcomes,” he said.
Positive data have been accumulating for colchicine from COLCOT, LoDoCo, and, most recently, the LoDoCo2 trial, even as another anti-inflammatory drug, methotrexate, flamed out as secondary prevention in the CIRT trial.
The new COLCOT substudy included 4,661 of the 4,745 original patients and examined treatment initiation using three strata: within 0-3 days (n = 1,193), 4-7 days (n = 720), and 8-30 days (n = 2,748). Patients who received treatment within 3 days were slightly younger, more likely to be smokers, and to have a shorter time from MI to randomization (2.1 days vs 5.1 days vs. 20.8 days, respectively).
In the subset receiving treatment within 3 days, those assigned to colchicine had the same number of cardiac deaths as those given placebo (2 vs. 2) but fewer resuscitated cardiac arrests (1 vs. 3), MIs (17 vs. 29), strokes (1 vs. 5), and urgent hospitalizations for angina requiring revascularization (6 vs. 17).
“A larger trial might have allowed for a better assessment of individual endpoints and subgroups,” observed Bouabdallaoui.
Although there is growing support for colchicine, experts caution that the drug many not be for everyone. In COLCOT, 1 in 10 patients were unable to tolerate the drug, largely because of gastrointestinal (GI) issues.
Pharmacogenomics substudy
A second COLCOT substudy aimed to identify genetic markers predictive of colchicine response and to gain insights into the mechanisms behind this response. It included 767 patients treated with colchicine and another 755 treated with placebo – or about one-third the patients in the original trial.
A genome-wide association study did not find a significant association for the primary CV endpoint, although a prespecified subgroup analysis in men identified an interesting region on chromosome 9 (variant: rs10811106), which just missed reaching genomewide significance, said Marie-Pierre Dubé, PhD, director of the Université de Montréal Beaulieu-Saucier Pharmacogenomics Centre at the Montreal Heart Institute.
In addition, the genomewide analysis found two significant regions for GI events: one on chromosome 6 (variant: rs6916345) and one on chromosome 10 (variant: rs74795203).
For each of the identified regions, the researchers then tested the effect of the allele in the placebo group and the interaction between the genetic variant and treatment with colchicine. For the chromosome 9 region in males, there was no effect in the placebo group and a significant interaction in the colchicine group.
For the significant GI event findings, there was a small effect for the chromosome 6 region in the placebo group and a very significant interaction with colchicine, Dubé said. Similarly, there was no effect for the chromosome 10 region in the placebo group and a significant interaction with colchicine.
Additional analyses in stratified patient populations showed that males with the protective allele (CC) for the chromosome 9 region represented 83% of the population. The primary CV endpoint occurred in 3.2% of these men treated with colchicine and 6.3% treated with placebo (HR, 0.46; 95% CI, 0.24 - 0.86).
For the gastrointestinal events, 25% of patients carried the risk allele (AA) for the chromosome 6 region and 36.9% of these had GI events when treated with colchicine versus 18.6% when treated with placebo (HR, 2.42; 95% CI, 1.57-3.72).
Similarly, 13% of individuals carried one or two copies of the risk allele (AG+GG) for the chromosome 10 region and the risk of GI events in these was nearly four times higher with colchicine (47.1% vs. 18.9%; HR, 3.98; 95% CI 2.24-7.07).
Functional genomic analyses of the identified regions were also performed and showed that the chromosome 9 locus overlaps with the SAXO1 gene, a stabilizer of axonemal microtubules 1.
“The leading variant at this locus (rs10811106 C allele) correlated with the expression of the HAUS6 gene, which is involved in microtubule generation from existing microtubules, and may interact with the effect of colchicine, which is known to inhibit microtubule formation,” observed Dubé.

Lessons for patients with MS and COVID-19
Two important lessons about managing patients with multiple sclerosis (MS) and COVID-19 have emerged from a hospital clinic in Madrid that managed COVID-infected patients with MS through the peak of the pandemic: Combined polymeric chain reaction and serology testing helped avoid disease reactivation in asymptomatic carriers during the pandemic peak, although after the peak PCR alone proved just as effective; and
Virginia Meca-Lallana, MD, a neurologist and coordinator of the demyelinating diseases unit at the Hospital of the University of the Princess in Madrid, and colleagues presented their findings in two posters at the Joint European Committee for Treatment and Research in Multiple Sclerosis-Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2020, this year known as MSVirtual2020.
“MS treatments don’t seem to make the prognosis of COVID-19 worse, but it is very important to evaluate other risk factors,” Dr. Meca-Lallana said in an interview. “MS treatments prevent the patients’ disability, and it is very important not to stop them if it isn’t necessary.”
The results arose from a multidisciplinary safety protocol involving neurology, microbiology, and preventive medicine that the University of Princess physicians developed to keep MS stable in patients diagnosed with SARS-CoV-2.
The researchers obtained 152 PCR nasopharyngeal swabs and 140 serology tests in 90 patients with MS over 3 months before starting a variety of MS treatments: Natalizumab (96 tests), ocrelizumab (36), rituximab (3), methylprednisolone (7), cladribine (4), and dimethyl fumarate (3). The protocol identified 7 asymptomatic carriers—7.8% of the total population—5 of whom had positive immunoglobulin M and G serology. The study also confirmed 5 patients with positive IgM+IgG serology post-infection, but no COVID-19 reactivations were detected after implementation of the protocol.
“The safety protocol reached its objective of avoiding disease reactivation and clinical activation in asymptomatic carriers,” Dr. Meca-Lallana said.
The second poster she presented reported on the real-world experience with SARS-CoV-2 in the MS unit at her hospital. The observational, prospective study included 41 cases, 38 of which were relapsing-remitting MS and the remainder progressive MS. The patients had MS for an average of 9 years.
“We need more patients to draw more robust conclusions, but in our patients, MS treatments seem safe in this situation,” Dr. Meca-Lallana said. “We did not discontinue treatments, and after our first results, we only delayed treatments in patients with any additional comorbidity or when coming to the hospital was not safe.”
A total of 39 patients were taking disease-modifying therapies (DMTs): 46.3% with oral agents, 39% with monoclonal antibodies, and 10% with injectable agents; 27 patients were previously treated with other DMTs. The median Expanded Disability Status Scale (EDSS) was 2.5, and 11 patients had clinical activity the previous year. Eighteen cases were confirmed by PCR or serology, or both, and 23 were diagnosed clinically.
Among the patients with MS and COVID-19, 17% were admitted to the hospital. Six patients had pneumonia, but none required admission to the intensive care unit, and no deaths occurred. Three patients had other comorbidities. Admitted patients tended to be older and had higher EDSS scores, although the difference was not statistically significant. MS worsened in 7 patients, and 10 patients stopped or paused DMTs because of the infection.
“Multiple sclerosis is a weakening illness,” Dr. Meca-Lallana said. “MS treatments do not seem to make the prognosis of COVID-19 worse, but it is very important to evaluate other risk factors.”
The SARS-CoV-2 infection does not seem to result in a more aggressive form of the disease in MS patients, and selective immunosuppression may improve their outcomes, she noted.
“MS treatments avoid the patient’s disability,” the investigator added, “and it is very important not to stop them if it isn’t necessary.”
Dr. Meca-Lallana had no relevant financial disclosures.

Distinguishing COVID-19 from flu in kids remains challenging
For children with COVID-19, rates of hospitalization, ICU admission, and ventilator use were similar to those of children with influenza, but rates differed in other respects, according to results of a study published online Sept. 11 in JAMA Network Open.
As winter approaches, distinguishing patients with COVID-19 from those with influenza will become a problem. To assist with that, Xiaoyan Song, PhD, director of the office of infection control and epidemiology at Children’s National Hospital in Washington, D.C., and colleagues investigated commonalities and differences between the clinical symptoms of COVID-19 and influenza in children.
“Distinguishing COVID-19 from flu and other respiratory viral infections remains a challenge to clinicians. Although our study showed that patients with COVID-19 were more likely than patients with flu to report fever, gastrointestinal, and other clinical symptoms at the time of diagnosis, the two groups do have many overlapping clinical symptoms,” Dr. Song said. “Until future data show us otherwise, clinicians need to prepare for managing coinfections of COVID-19 with flu and/or other respiratory viral infections in the upcoming flu season.”
The retrospective cohort study included 315 children diagnosed with laboratory-confirmed COVID-19 between March 25 and May 15, 2020, and 1,402 children diagnosed with laboratory-confirmed seasonal influenza A or influenza B between Oct. 1, 2019, and June 6, 2020, at Children’s National Hospital. The investigation excluded asymptomatic patients who tested positive for COVID-19.
Patients with COVID-19 and patients with influenza were similar with respect to rates of hospitalization (17% vs. 21%; odds ratio, 0.8; 95% confidence interval, 0.6-1.1; P = .15), admission to the ICU (6% vs. 7%; OR, 0.8; 95% CI, 0.5-1.3; P = .42), and use of mechanical ventilation (3% vs. 2%; OR, 1.5; 95% CI, 0.9-2.6; P =.17).
The difference in the duration of ventilation for the two groups was not statistically significant. None of the patients who had COVID-19 or influenza B died, but two patients with influenza A did.
No patients had coinfections, which the researchers attribute to the mid-March shutdown of many schools, which they believe limited the spread of seasonal influenza.
Patients who were hospitalized with COVID-19 were older (median age, 9.7 years; range, 0.06-23.2 years) than those hospitalized with either type of influenza (median age, 4.2 years; range, 0.04-23.1). Patients older than 15 years made up 37% of patients with COVID-19 but only 6% of those with influenza.
Among patients hospitalized with COVID-19, 65% had at least one underlying medical condition, compared with 42% of those hospitalized for either type of influenza (OR, 2.6; 95% CI, 1.4-4.7; P = .002).
The most common underlying condition was neurologic problems from global developmental delay or seizures, identified in 11 patients (20%) hospitalized with COVID-19 and in 24 patients (8%) hospitalized with influenza (OR, 2.8; 95% CI, 1.3-6.2; P = .002). There was no significant difference between the two groups with respect to a history of asthma, cardiac disease, hematologic disease, and cancer.
For both groups, fever and cough were the most frequently reported symptoms at the time of diagnosis. However, more patients hospitalized with COVID-19 reported fever (76% vs. 55%; OR, 2.6; 95% CI, 1.4-5.1; P = 01), diarrhea or vomiting (26% vs. 12%; OR, 2.5; 95% CI, 1.2-5.0; P = .01), headache (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01), myalgia (22% vs. 7%; OR, 3.9; 95% CI, 1.8-8.5; P = .001), or chest pain (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01).
The researchers found no statistically significant differences between the two groups in rates of cough, congestion, sore throat, or shortness of breath.
Comparison of the symptom spectrum between COVID-19 and flu differed with respect to influenza type. More patients with COVID-19 reported fever, cough, diarrhea and vomiting, and myalgia than patients hospitalized with influenza A. But rates of fever, cough, diarrhea or vomiting, headache, or chest pain didn’t differ significantly in patients with COVID-19 and those with influenza B.
Larry K. Kociolek, MD, medical director of infection prevention and control at Ann and Robert H. Lurie Children’s Hospital of Chicago, noted the lower age of patients with flu. “Differentiating the two infections, which is difficult if not impossible based on symptoms alone, may have prognostic implications, depending on the age of the child. Because this study was performed outside peak influenza season, when coinfections would be less likely to occur, we must be vigilant about the potential clinical implications of influenza and SARS-CoV-2 coinfection this fall and winter.”
Clinicians will still have to use a combination of symptoms, examinations, and testing to distinguish the two diseases, said Aimee Sznewajs, MD, medical director of the pediatric hospital medicine department at Children’s Minnesota, Minneapolis. “We will continue to test for influenza and COVID-19 prior to hospitalizations and make decisions about whether to hospitalize based on other clinical factors, such as dehydration, oxygen requirement, and vital sign changes.”
Dr. Sznewajs stressed the importance of maintaining public health strategies, including “ensuring all children get the flu vaccine, encouraging mask wearing and hand hygiene, adequate testing to determine which virus is present, and other mitigation measures if the prevalence of COVID-19 is increasing in the community.”
Dr. Song reiterated those points, noting that clinicians need to make the most of the options they have. “Clinicians already have many great tools on hand. It is extremely important to get the flu vaccine now, especially for kids with underlying medical conditions. Diagnostic tests are available for both COVID-19 and flu. Antiviral treatment for flu is available. Judicious use of these tools will protect the health of providers, kids, and well-being at large.”
The authors noted several limitations for the study, including its retrospective design, that the data came from a single center, and that different platforms were used to detect the viruses.

Antiviral treatment for flu is available. Judicious use of these tools will protect the health of providers, kids, and well-being at large.”
The authors noted several limitations for the study, including its retrospective design, that the data came from a single center, and that different platforms were used to detect the viruses.

For children with COVID-19, rates of hospitalization, ICU admission, and ventilator use were similar to those of children with influenza, but rates differed in other respects, according to results of a study published online Sept. 11 in JAMA Network Open.
As winter approaches, distinguishing patients with COVID-19 from those with influenza will become a problem. To assist with that, Xiaoyan Song, PhD, director of the office of infection control and epidemiology at Children’s National Hospital in Washington, D.C., and colleagues investigated commonalities and differences between the clinical symptoms of COVID-19 and influenza in children.
“Distinguishing COVID-19 from flu and other respiratory viral infections remains a challenge to clinicians. Although our study showed that patients with COVID-19 were more likely than patients with flu to report fever, gastrointestinal, and other clinical symptoms at the time of diagnosis, the two groups do have many overlapping clinical symptoms,” Dr. Song said. “Until future data show us otherwise, clinicians need to prepare for managing coinfections of COVID-19 with flu and/or other respiratory viral infections in the upcoming flu season.”
The retrospective cohort study included 315 children diagnosed with laboratory-confirmed COVID-19 between March 25 and May 15, 2020, and 1,402 children diagnosed with laboratory-confirmed seasonal influenza A or influenza B between Oct. 1, 2019, and June 6, 2020, at Children’s National Hospital. The investigation excluded asymptomatic patients who tested positive for COVID-19.
Patients with COVID-19 and patients with influenza were similar with respect to rates of hospitalization (17% vs. 21%; odds ratio, 0.8; 95% confidence interval, 0.6-1.1; P = .15), admission to the ICU (6% vs. 7%; OR, 0.8; 95% CI, 0.5-1.3; P = .42), and use of mechanical ventilation (3% vs. 2%; OR, 1.5; 95% CI, 0.9-2.6; P =.17).
The difference in the duration of ventilation for the two groups was not statistically significant. None of the patients who had COVID-19 or influenza B died, but two patients with influenza A did.
No patients had coinfections, which the researchers attribute to the mid-March shutdown of many schools, which they believe limited the spread of seasonal influenza.
Patients who were hospitalized with COVID-19 were older (median age, 9.7 years; range, 0.06-23.2 years) than those hospitalized with either type of influenza (median age, 4.2 years; range, 0.04-23.1). Patients older than 15 years made up 37% of patients with COVID-19 but only 6% of those with influenza.
Among patients hospitalized with COVID-19, 65% had at least one underlying medical condition, compared with 42% of those hospitalized for either type of influenza (OR, 2.6; 95% CI, 1.4-4.7; P = .002).
The most common underlying condition was neurologic problems from global developmental delay or seizures, identified in 11 patients (20%) hospitalized with COVID-19 and in 24 patients (8%) hospitalized with influenza (OR, 2.8; 95% CI, 1.3-6.2; P = .002). There was no significant difference between the two groups with respect to a history of asthma, cardiac disease, hematologic disease, and cancer.
For both groups, fever and cough were the most frequently reported symptoms at the time of diagnosis. However, more patients hospitalized with COVID-19 reported fever (76% vs. 55%; OR, 2.6; 95% CI, 1.4-5.1; P = 01), diarrhea or vomiting (26% vs. 12%; OR, 2.5; 95% CI, 1.2-5.0; P = .01), headache (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01), myalgia (22% vs. 7%; OR, 3.9; 95% CI, 1.8-8.5; P = .001), or chest pain (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01).
The researchers found no statistically significant differences between the two groups in rates of cough, congestion, sore throat, or shortness of breath.
Comparison of the symptom spectrum between COVID-19 and flu differed with respect to influenza type. More patients with COVID-19 reported fever, cough, diarrhea and vomiting, and myalgia than patients hospitalized with influenza A. But rates of fever, cough, diarrhea or vomiting, headache, or chest pain didn’t differ significantly in patients with COVID-19 and those with influenza B.
Larry K. Kociolek, MD, medical director of infection prevention and control at Ann and Robert H. Lurie Children’s Hospital of Chicago, noted the lower age of patients with flu. “Differentiating the two infections, which is difficult if not impossible based on symptoms alone, may have prognostic implications, depending on the age of the child. Because this study was performed outside peak influenza season, when coinfections would be less likely to occur, we must be vigilant about the potential clinical implications of influenza and SARS-CoV-2 coinfection this fall and winter.”
Clinicians will still have to use a combination of symptoms, examinations, and testing to distinguish the two diseases, said Aimee Sznewajs, MD, medical director of the pediatric hospital medicine department at Children’s Minnesota, Minneapolis. “We will continue to test for influenza and COVID-19 prior to hospitalizations and make decisions about whether to hospitalize based on other clinical factors, such as dehydration, oxygen requirement, and vital sign changes.”
Dr. Sznewajs stressed the importance of maintaining public health strategies, including “ensuring all children get the flu vaccine, encouraging mask wearing and hand hygiene, adequate testing to determine which virus is present, and other mitigation measures if the prevalence of COVID-19 is increasing in the community.”
Dr. Song reiterated those points, noting that clinicians need to make the most of the options they have. “Clinicians already have many great tools on hand. It is extremely important to get the flu vaccine now, especially for kids with underlying medical conditions. Diagnostic tests are available for both COVID-19 and flu. Antiviral treatment for flu is available. Judicious use of these tools will protect the health of providers, kids, and well-being at large.”

AI can pinpoint COVID-19 from chest x-rays
Conventional chest x-rays combined with artificial intelligence (AI) can identify lung damage from COVID-19 and differentiate coronavirus patients from other patients, improving triage efforts, new research suggests.
The AI tool – developed by Jason Fleischer, PhD, and graduate student Mohammad Tariqul Islam, both from Princeton (N.J.) University – can distinguish COVID-19 patients from those with pneumonia or normal lung tissue with an accuracy of more than 95%.
“We were able to separate the COVID-19 patients with very high fidelity,” Dr. Fleischer said in an interview. “If you give me an x-ray now, I can say with very high confidence whether a patient has COVID-19.”
The diagnostic tool pinpoints patterns on x-ray images that are too subtle for even trained experts to notice. The precision of CT scanning is similar to that of the AI tool, but CT costs much more and has other disadvantages, said Dr. Fleischer, who presented his findings at the virtual European Respiratory Society International Congress 2020.
“CT is more expensive and uses higher doses of radiation,” he said. “Another big thing is that not everyone has tomography facilities – including a lot of rural places and developing countries – so you need something that’s on the spot.”
With machine learning, Dr. Fleischer analyzed 2,300 x-ray images: 1,018 “normal” images from patients who had neither pneumonia nor COVID-19, 1,011 from patients with pneumonia, and 271 from patients with COVID-19.
The AI tool uses a neural network to refine the number and type of lung features being tracked. A UMAP (Uniform Manifold Approximation and Projection) clustering algorithm then looks for similarities and differences in those images, he explained.
“We, as users, knew which type each x-ray was – normal, pneumonia positive, or COVID-19 positive – but the network did not,” he added.
Clinicians have observed two basic types of lung problems in COVID-19 patients: pneumonia that fills lung air sacs with fluid and dangerously low blood-oxygen levels despite nearly normal breathing patterns. Because treatment can vary according to type, it would be beneficial to quickly distinguish between them, Dr. Fleischer said.
The AI tool showed that there is a distinct difference in chest x-rays from pneumonia-positive patients and healthy people, he said. It also demonstrated two distinct clusters of COVID-19–positive chest x-rays: those that looked like pneumonia and those with a more normal presentation.
The fact that “the AI system recognizes something unique in chest x-rays from COVID-19–positive patients” indicates that the computer is able to identify visual markers for coronavirus, he explained. “We currently do not know what these markers are.”
Dr. Fleischer said his goal is not to replace physician decision-making, but to supplement it.
“I’m uncomfortable with having computers make the final decision,” he said. “They often have a narrow focus, whereas doctors have the big picture in mind.”
This AI tool is “very interesting,” especially in the context of expanding AI applications in various specialties, said Thierry Fumeaux, MD, from Nyon (Switzerland) Hospital. Some physicians currently disagree on whether a chest x-ray or CT scan is the better tool to help diagnose COVID-19.
“It seems better than the human eye and brain” to pinpoint COVID-19 lung damage, “so it’s very attractive as a technology,” Dr. Fumeaux said in an interview.
And AI can be used to supplement the efforts of busy and fatigued clinicians who might be stretched thin by large caseloads. “I cannot read 200 chest x-rays in a day, but a computer can do that in 2 minutes,” he said.
But Dr. Fumeaux offered a caveat: “Pattern recognition is promising, but at the moment I’m not aware of papers showing that, by using AI, you’re changing anything in the outcome of a patient.”
Ideally, Dr. Fleischer said he hopes that AI will soon be able to accurately indicate which treatments are most effective for individual COVID-19 patients. And the technology might eventually be used to help with treatment decisions for patients with asthma or chronic obstructive pulmonary disease, he noted.
But he needs more data before results indicate whether a COVID-19 patient would benefit from ventilator support, for example, and the tool can be used more widely. To contribute data or collaborate with Dr. Fleischer’s efforts, contact him.
“Machine learning is all about data, so you can find these correlations,” he said. “It would be nice to be able to use it to reassure a worried patient that their prognosis is good; to say that most of the people with symptoms like yours will be just fine.”
Dr. Fleischer and Dr. Fumeaux have declared no relevant financial relationships.

Social distancing impacts other infectious diseases
Diagnoses of 12 common pediatric infectious diseases in a large pediatric primary care network declined significantly in the weeks after COVID-19 social distancing (SD) was enacted in Massachusetts, compared with the same time period in 2019, an analysis of EHR data has shown.
While declines in infectious disease transmission with SD are not surprising, “these data demonstrate the extent to which transmission of common pediatric infections can be altered when close contact with other children is eliminated,” Jonathan Hatoun, MD, MPH of the Pediatric Physicians’ Organization at Children’s in Brookline, Mass., and coauthors wrote in Pediatrics . “Notably, three of the studied diseases, namely, influenza, croup, and bronchiolitis, essentially disappeared with [social distancing].”
The researchers analyzed the weekly incidence of each diagnosis for similar calendar periods in 2019 and 2020. A pre-SD period was defined as week 1-9, starting on Jan. 1, and a post-SD period was defined as week 13-18. (The several-week gap represented an implementation period as social distancing was enacted in the state earlier in 2020, from a declared statewide state of emergency through school closures and stay-at-home advisories.)
To isolate the effect of widespread SD, they performed a “difference-in-differences regression analysis, with diagnosis count as a function of calendar year, time period (pre-SD versus post-SD) and the interaction between the two.” The Massachusetts pediatric network provides care for approximately 375,000 children in 100 locations around the state.
In their research brief, Dr. Hatoun and coauthors presented weekly rates expressed as diagnoses per 100,000 patients per day. The rate of bronchiolitis, for instance, was 18 and 8 in the pre- and post-SD–equivalent weeks of 2019, respectively, and 20 and 0.6 in the pre- and post-SD weeks of 2020. Their analysis showed the rate in the 2020 post-SD period to be 10 diagnoses per 100,000 patients per day lower than they would have expected based on the 2019 trend.
Rates of pneumonia, acute otitis media, and streptococcal pharyngitis were similarly 14, 85, and 31 diagnoses per 100,000 patients per day lower, respectively. The prevalence of each of the other conditions analyzed – the common cold, croup, gastroenteritis, nonstreptococcal pharyngitis, sinusitis, skin and soft tissue infections, and urinary tract infection (UTI) – also was significantly lower in the 2020 post-SD period than would be expected based on 2019 data (P < .001 for all diagnoses).
Putting things in perspective
“This study puts numbers to the sense that we have all had in pediatrics – that social distancing appears to have had a dramatic impact on the transmission of common childhood infectious diseases, especially other respiratory viral pathogens,” Audrey R. John, MD, PhD, chief of the division of pediatric infectious disease at Children’s Hospital of Philadelphia, said in an interview.
The authors acknowledged the possible role of families not seeking care, but said that a smaller decrease in diagnoses of UTI – generally not a contagious disease – “suggests that changes in care-seeking behavior had a relatively modest effect on the other observed declines.” (The rate of UTI for the pre- and post-SD periods was 3.3 and 3.7 per 100,000 patients per day in 2019, and 3.4 and 2.4 in 2020, for a difference in differences of –1.5).
In an accompanying editorial, David W. Kimberlin, MD and Erica C. Bjornstad, MD, PhD, MPH, of the University of Alabama at Birmingham, called the report “provocative” and wrote that similar observations of infections dropping during periods of isolation – namely, dramatic declines in influenza and other respiratory viruses in Seattle after a record snowstorm in 2019 – combined with findings from other modeling studies “suggest that the decline [reported in Boston] is indeed real” (Pediatrics 2020. doi: 10.1542/peds.2020-019232).
However, “we also now know that immunization rates for American children have plummeted since the onset of the SARS-CoV-2 pandemic [because of a] ... dramatic decrease in the use of health care during the first months of the pandemic,” they wrote. “Viewed through this lens,” the declines reported in Boston may reflect inflections going “undiagnosed and untreated.”
Ultimately, Dr. Kimberlin and Dr. Bjornstad said, “the verdict remains out.”
Dr. John said that she and others are “concerned about children not seeking care in a timely manner, and [concerned] that reductions in reported infections might be due to a lack of recognition rather than a lack of transmission.”
In Philadelphia, however, declines in admissions for asthma exacerbations, “which are often caused by respiratory viral infections, suggests that this may not be the case,” said Dr. John, who was asked to comment on the study.
In addition, she said, the Massachusetts data showing that UTI diagnoses “are nearly as common this year as in 2019” are “reassuring.”
Are there lessons for the future?
Coauthor Louis Vernacchio, MD, MSc, chief medical officer of the Pediatric Physicians’ Organization at Children’s network, said in an interview that beyond the pandemic, it’s likely that “more careful attention to proven infection control practices in daycares and schools could reduce the burden of common infectious diseases in children.”
Dr. John similarly sees a long-term value of quantifying the impact of social distancing. “We’ve always known [for instance] that bronchiolitis is the result of viral infection.” Findings like the Massachusetts data “will help us advise families who might be trying to protect their premature infants (at risk for severe bronchiolitis) through social distancing.”
The analysis covered both in-person and telemedicine encounters occurring on weekdays.
The authors of the research brief indicated they have no relevant financial disclosures and there was no external funding. The authors of the commentary also reported they have no relevant financial disclosures, and Dr. John said she had no relevant financial disclosures.

(The several-week gap represented an implementation period as social distancing was enacted in the state earlier in 2020, from a declared statewide state of emergency through school closures and stay-at-home advisories.)
To isolate the effect of widespread SD, they performed a “difference-in-differences regression analysis, with diagnosis count as a function of calendar year, time period (pre-SD versus post-SD) and the interaction between the two.” The Massachusetts pediatric network provides care for approximately 375,000 children in 100 locations around the state.
In their research brief, Dr. Hatoun and coauthors presented weekly rates expressed as diagnoses per 100,000 patients per day. The rate of bronchiolitis, for instance, was 18 and 8 in the pre- and post-SD–equivalent weeks of 2019, respectively, and 20 and 0.6 in the pre- and post-SD weeks of 2020. Their analysis showed the rate in the 2020 post-SD period to be 10 diagnoses per 100,000 patients per day lower than they would have expected based on the 2019 trend.
Rates of pneumonia, acute otitis media, and streptococcal pharyngitis were similarly 14, 85, and 31 diagnoses per 100,000 patients per day lower, respectively. The prevalence of each of the other conditions analyzed – the common cold, croup, gastroenteritis, nonstreptococcal pharyngitis, sinusitis, skin and soft tissue infections, and urinary tract infection (UTI) – also was significantly lower in the 2020 post-SD period than would be expected based on 2019 data (P < .001 for all diagnoses).
Putting things in perspective
“This study puts numbers to the sense that we have all had in pediatrics – that social distancing appears to have had a dramatic impact on the transmission of common childhood infectious diseases, especially other respiratory viral pathogens,” Audrey R. John, MD, PhD, chief of the division of pediatric infectious disease at Children’s Hospital of Philadelphia, said in an interview.
The authors acknowledged the possible role of families not seeking care, but said that a smaller decrease in diagnoses of UTI – generally not a contagious disease – “suggests that changes in care-seeking behavior had a relatively modest effect on the other observed declines.” (The rate of UTI for the pre- and post-SD periods was 3.3 and 3.7 per 100,000 patients per day in 2019, and 3.4 and 2.4 in 2020, for a difference in differences of –1.5).
In an accompanying editorial, David W. Kimberlin, MD and Erica C. Bjornstad, MD, PhD, MPH, of the University of Alabama at Birmingham, called the report “provocative” and wrote that similar observations of infections dropping during periods of isolation – namely, dramatic declines in influenza and other respiratory viruses in Seattle after a record snowstorm in 2019 – combined with findings from other modeling studies “suggest that the decline [reported in Boston] is indeed real” (Pediatrics 2020. doi: 10.1542/peds.2020-019232).
However, “we also now know that immunization rates for American children have plummeted since the onset of the SARS-CoV-2 pandemic [because of a] ... dramatic decrease in the use of health care during the first months of the pandemic,” they wrote. “Viewed through this lens,” the declines reported in Boston may reflect inflections going “undiagnosed and untreated.”
Ultimately, Dr. Kimberlin and Dr. Bjornstad said, “the verdict remains out.”
Dr. John said that she and others are “concerned about children not seeking care in a timely manner, and [concerned] that reductions in reported infections might be due to a lack of recognition rather than a lack of transmission.”
In Philadelphia, however, declines in admissions for asthma exacerbations, “which are often caused by respiratory viral infections, suggests that this may not be the case,” said Dr. John, who was asked to comment on the study.
In addition, she said, the Massachusetts data showing that UTI diagnoses “are nearly as common this year as in 2019” are “reassuring.”
Are there lessons for the future?
Coauthor Louis Vernacchio, MD, MSc, chief medical officer of the Pediatric Physicians’ Organization at Children’s network, said in an interview that beyond the pandemic, it’s likely that “more careful attention to proven infection control practices in daycares and schools could reduce the burden of common infectious diseases in children.”
Dr. John similarly sees a long-term value of quantifying the impact of social distancing. “We’ve always known [for instance] that bronchiolitis is the result of viral infection.” Findings like the Massachusetts data “will help us advise families who might be trying to protect their premature infants (at risk for severe bronchiolitis) through social distancing.”
The analysis covered both in-person and telemedicine encounters occurring on weekdays.
The authors of the research brief indicated they have no relevant financial disclosures and there was no external funding. The authors of the commentary also reported they have no relevant financial disclosures, and Dr. John said she had no relevant financial disclosures.

Dangers behind antimaskers and antivaxxers: How to combat both
Niket Sonpal, MD, thought he’d heard most of the myths about wearing masks during the pandemic, but the recent claim from a patient was a new one for the New York City gastroenterologist.
The patient refused to wear a mask because she heard inhaling bad breath through a mask could be toxic. The woman said the rumor was circulating on Facebook. Sonpal calmly explained that breathing your own breath is not going to cause health problems, he said.
“There’s a lot of controversy on masks,” he said. “Unfortunately, it’s really just a lack of education and buy-in. Social media is the primary source of all this misinformation. These kinds of over-the-top hyperbole has basically led to a disbelief that masks are effective. The disbelief is hard to break up.”
As mask requirements have tightened amid the ongoing pandemic, debates about face coverings have emerged front and center, with a growing number of people opposing mask usage. So-called antimaskers dispute the benefits of wearing masks and many contend that face coverings decrease oxygen flow and can lead to illness. Sentiment against masks have led to protests nationwide, ignited public conflicts in some areas, and even generated lawsuits over mask mandates.
The issue presents an ongoing challenge for physicians as they strive to educate patients about the significance of masking against the flood of antimask messages on social media and beyond. Opposition to masks is particularly frustrating for health professionals who have witnessed patients, family, or friends become ill or die from the virus. Refusing to mask and failing to social distance have been linked to the rapid spread of the coronavirus and subsequent deaths.
“I have had colleagues pass away, and it’s extremely disheartening and frustrating to see science so easily disregarded,” Sonpal said. “Masks save lives and protect people and not wearing them is simply a lack of respect, not just for your fellow colleagues, but for a member of your species.”
Michael Rebresh, who helped create the antimask group Million Unmasked Patriots, says his group’s objections to masks are rational and reasonable. The group, which has more than 8,000 members, formed in response to guidance by Illinois state officials that children would only be allowed to return to school wearing a mask.
“Our objections are to the fact that masks on children in school have a greater propensity to make children sick from breathing in bacteria that forms on the inner layer of a mask worn for hours on end,” Rebresh said. “We have an objection to the increase of CO2 intake and a decrease in oxygen flow for kids who need all the oxygen they can get during a learning environment. We recognized the masking of ourselves and kids for what it is: A political move to separate the two parties in our November election and define and create division between the two.”
Million Unmasked Patriots is one of dozens of antimask groups on social media platforms such as Facebook, Instagram, and TikTok. In July, Facebook suspended one such group, Unmasking America, which boasts 9,600 members, for posting repeated claims that face masks obstruct oxygen flow and have negative mental health effects.
Experts say the antiscience rhetoric is far from new. The antimask movement in many ways, shares similarities with that of the anti-vaccine movement, says Todd Wolynn, MD, a Pittsburgh pediatrician and cofounder of Shots Heard Round the World, an organization that defends vaccine advocates against coordinated online attacks by antivaxxers.
“A lot of it is conspiracy-laden,” said Wolynn of the disinformation. “That Dr. [Anthony] Fauci somehow helped construct the pandemic and that it’s not real. That Bill Gates is funding the vaccine so he can inject people with microchips. All sorts of really out-there, ungrounded conspiracy theories. If you had Venn diagram of antimask and antivaxx, I would say there’s clearly overlap.”
Parallels between antimaskers, antivaxxers
Opponents to masks fall on a spectrum, explains Vineet Arora, MD, a hospitalist and associate chief medical officer–clinical learning environment at University of Chicago Medicine. People who believe conspiracy theories and push misinformation are on one end, she said. There are also those who generally don’t believe the seriousness of the pandemic, feel their risk is minimal, or doubt the benefits of masks.
The two trains of thought resemble the distinction among parents who are antivaccine and those who are simply “vaccine hesitant,” says Arora, who co-authored a recent article about masking and misinformation that addresses antivaccine attitudes.
“While the antimask sentiment gets a lot of attention, I think it’s important to highlight there’s a lot of vocal anti-mask sentiment since most people are supportive of masks,” she said. “There might be people sitting on the fence who are just unsure about wearing a mask. That’s understandable because the science and the communication has evolved. There was a lot of early mixed messages about masking. Anytime you have confusion about the science or the science is evolving, it’s easy to have misinformation and then have that take off as myth.”
Just as antivaxxers work to swing the opinion of the vaccine hesitant, antimaskers are vying with public health advocates for the support of the mask hesitant, she said. Creating doubt in public health authorities is one way they are gaining followers. Anti-maskers often question and scrutinize past messaging about masks by public health officials, claiming that because guidance on masks has changed over time, the science behind masks and current guidance can’t be trusted, Wolynn said. Similarly, antivaxxers frequently question past actions by public health officials, such as the Tuskegee Experiment (which began in 1932), to try to poke holes in the credibility of public health officials and their advice.
Both the antimask and antivaccine movements also tend to base their resistance on a personal liberties argument, adds Jacqueline Winfield Fincher, MD, president for the American College of Physicians and an internist based in Thomson, Georgia. Antimaskers contend they should be free to decide whether to wear face coverings and that rules requiring masks infringe upon their civil liberties. Similarly, antivaxxers argue they should be free to decide whether to vaccinate their children and contend vaccine mandates violate their personal liberties.
Taking a deeper look, fear and control are two likely drivers of antimasking and antivaccine attitudes, Fincher said. Those refusing to wear masks may feel they have no control over the pandemic or its impacts, but they can control how they respond to mask-wearing requirements, she said.
Antivaccine parents often want more control over their children’s healthcare and falsely believe that vaccines are injecting something harmful into their children or may lead to harmful reactions.
“It’s a control issue and a defense mechanism,” she said. “Some people may feel helpless to deal with the pandemic or believe since it is not affecting them or their family, that it is not real. ‘If I just deny it and I don’t acknowledge facts, I don’t have to worry about it or do anything about it, and therefore I will have more control over my day-to-day life.’”
Groups fueling each other
In some cases, antimask and antivaxx groups are joining forces or adopting dual causes.
In California for instance, longtime opponents to vaccines are now objecting to mask policies as similar infringement to their bodily autonomy. Demonstrations in Texas, Idaho, and Michigan against mask mandates and other COVID-19 requirements have drawn support from anti-vaccine activists and incorporated antivaccine propaganda.
In Illinois, Million Unmasked Patriots, formally the Million Unmasked March, has received widespread attention for protesting both masks for returning schoolchildren and a future COVID-19 vaccine requirement.
A July protest planned by the antimask group triggered a letter by Arora and 500 other healthcare professionals to Illinois lawmakers decrying the group’s views and urging the state to move forward with universal masking in schools.
“What’s happening is those who are distrustful of government and public health and science are joining together,” said Arora, who coauthored a piece about the problem on KevinMD.com. “It’s important to address both movements together because they can quickly feed off each other and build in momentum. At the heart of both is really this deep skepticism of science.”
Rebresh of Million Unmasked Patriots said most of his members are not opposed to all vaccines, but rather they are opposed to “untested vaccines.” The primary concern is the inability to research long-term effects of a COVID-19 vaccine before its approval, he said.
Rebresh disagrees with the antimask movement being compared with the antivaccine movement. The two groups are “motivated by different things and a different set of circumstances drive their opinions,” he said. However, Rebresh believes that potential harm resulting from “mass vaccinations” is a valid concern. For this reason, he and his wife chose for their children to receive their vaccinations individually over a series of weeks, rather than the “kiddie cocktail of vaccines,” at a single visit, he said.
Vaccine scientist Peter Hotez, MD, PhD, said the antivaccine movement appears to have grown stronger from the pandemic fueled by fresh conspiracies and new alliances. Antivaccine sentiment has been gaining steam over the last several years and collecting more allies from the far-right, said Hotez, dean for the National School of Tropical Medicine and codirector for the Texas Children’s Hospital Center for Vaccine Development.
“Now what you’re seeing is yet another expansion this year, with antivaccine groups, under the banner of ‘health freedom,’ campaigning against social distancing and wearing masks and contact tracing,” he said. “What was an antivaccine movement has now become a full-blown antiscience movement and an anti-public health movement. It’s causing a lot of damage and I believe costing a lot of American lives.”
Neil F. Johnson, PhD, who has studied the antivaccine movement and its social media proliferation during the pandemic, said online comments by antivaxxers frequently condemn mask usage and showcase memes making fun of masks.
“In those same narratives about opposing vaccines for COVID, we see a lot of discussion against masks,” said Johnson, a physics professor at George Washington University in Washington, D.C. “If you don’t believe in the official picture of COVID, you don’t believe the policies or the advice that’s given about COVID.”
An analysis by Johnson that examined 1,300 Facebook pages found that, while antivaxxers have fewer followers than provaccine pages, antivaccine pages are more numerous, faster growing, and are more often connected to unrelated, undecided pages. Conversely, pages that advocate the benefits of vaccinations and explain the science behind immunizations are largely disconnected from such undecided communities, according to the study, published May 13 in Nature.
The study suggests the antivaccine movement is making influential strides during the pandemic and connecting with people who are undecided, while public health advocates are not building the same bridges, Johnson said.
“I think it’s hugely dangerous, because I don’t know any other moment in science or in public health when there was so much uncertainty in something affecting everybody,” he said. “Every policy that will be coming, everything depends on people buying into the official message. Once you have the seeds of doubt, that’s a very difficult thing to overcome. It’s an unprecedented challenge.”
How physicians and clinicians can help
A more aggressive approach is necessary when it comes to taking down antiscience content on social media, says Hotez. Too often, misinformation and antiscience rhetoric is allowed to linger on popular sites such as Facebook and Amazon.
Wolynn agrees. On personal or business platforms, it’s crucial to ban, hide, and delete such comments as quickly as possible, he said. On public sites, purposeful disinformation should be immediately reported to the platform.
At the same time, Wolynn said it’s essential to support those who make sound, science-based comments in social media forums.
“If you see someone who is pushing accurate, evidence-based information, and they come under attack, they should be supported and defended and empowered,” Wolynn said. “Shots Heard Round the World is doing all of those things, including galvanizing and recruiting more people to help get their voices out there.”
Expanded visibility by physicians and scientists would greatly help counter the spread of antiscience sentiment, adds Hotez.
“Too often, antiscience movements are able to flourish because scientists and physicians are invisible,” he said. “They’re too focused on either clinical practices or in the case of physician scientists, on grants and papers and not enough attention to public engagement. We’re going to have to change that around. We need to hear more from scientists directly.”
To that end, Wolynn said health care professionals, including medical students and residents, need to have formal training in communications, media, and social media as part of their education – and more support from employers to engage through social media.
“That’s where the fight is,” Wolynn said. “You can be the best diagnostician, the best clinician. You can make the right diagnosis and prescribe the right medication, but if families don’t hear what you’re saying, you’re not going to be effective. If you can’t be on the platform where they’re being influenced, we’re losing the battle.”
Speaking to your mask-hesitant patients
Concentrating on those who are uncertain about masks is particularly key for physicians and public health advocates as the pandemic continues, says Arora.
“It’s important for us to focus on the mask-hesitant who often don’t get the attention they need,” she said.
She suggests bringing up the subject of masks with patients during visits, asking about mask usage, discussing rumors they’ve heard, and emphasizing why masks are important. Be a role model by wearing a mask in your community and on social media, she added.
Some patients have real concerns about not being able to breathe through masks or anxiety disorders that can be aggravated even by the thought of wearing a mask, noted Susan R. Bailey, MD, president for the American Medical Association. Bailey, an immunologist, recently counseled a patient with a deviated nasal septum in addition to a panic disorder who was worried about wearing a mask, she said. Bailey listened to the patient’s concerns, discussed his health conditions, and proposed an alternative face covering that might make him more comfortable.
“Every patient is different,” Bailey said. “It’s important for us to remember that each person who is reluctant to wear a mask has their own reasons. It’s important for us to express some empathy – to agree with them, yes, masks are hot and inconvenient – and help understand their questions, which you may be able to answer to their satisfaction. There are patients that have legitimate questions and a physician caring about how they feel, can make all the difference.”
Physicians can also get involved with the AMA’s #MaskUp campaign, an effort to normalize mask wearing and debunk myths associated with masks. The campaign includes social media materials, slogans doctors can tweet, and profile pictures they can use on social media. The campaign’s toolkit includes images, videos, and information that physicians can share with patients and the public.
Enforcing strong mask policies at your practice and ensuring all staff are modeling appropriate mask behavior is also important, adds Fincher of the ACP. The college recently issued a policy supporting mask usage in community settings.
If a patient conveys an antimask belief, Fincher suggests not directly challenging the person’s views, but listening to them and offering objective data, discussing the science behind masks, and directing them to credible sources.
“Doctors are used to this. We recommend a lot of things to patients that they don’t want to do,” Fincher said. “If a patient feels attacked, they act defensively. But if you base your explanation in more objective terms with data, numbers, and personalize the risks and benefits of a vaccine, a healthy change in behavior, or a medication, then patients are more likely to hear your concerns and do the right thing. Having a long-term relationship with a trusted physician makes all of these issues much easier to discuss and to implement the best plan for the individual patient.”

Enforcing strong mask policies at your practice and ensuring all staff are modeling appropriate mask behavior is also important, adds Fincher of the ACP. The college recently issued a policy supporting mask usage in community settings.
If a patient conveys an antimask belief, Fincher suggests not directly challenging the person’s views, but listening to them and offering objective data, discussing the science behind masks, and directing them to credible sources.
“Doctors are used to this. We recommend a lot of things to patients that they don’t want to do,” Fincher said. “If a patient feels attacked, they act defensively. But if you base your explanation in more objective terms with data, numbers, and personalize the risks and benefits of a vaccine, a healthy change in behavior, or a medication, then patients are more likely to hear your concerns and do the right thing. Having a long-term relationship with a trusted physician makes all of these issues much easier to discuss and to implement the best plan for the individual patient.”

Niket Sonpal, MD, thought he’d heard most of the myths about wearing masks during the pandemic, but the recent claim from a patient was a new one for the New York City gastroenterologist.
The patient refused to wear a mask because she heard inhaling bad breath through a mask could be toxic. The woman said the rumor was circulating on Facebook. Sonpal calmly explained that breathing your own breath is not going to cause health problems, he said.
“There’s a lot of controversy on masks,” he said. “Unfortunately, it’s really just a lack of education and buy-in. Social media is the primary source of all this misinformation. These kinds of over-the-top hyperbole has basically led to a disbelief that masks are effective. The disbelief is hard to break up.”
As mask requirements have tightened amid the ongoing pandemic, debates about face coverings have emerged front and center, with a growing number of people opposing mask usage. So-called antimaskers dispute the benefits of wearing masks and many contend that face coverings decrease oxygen flow and can lead to illness. Sentiment against masks have led to protests nationwide, ignited public conflicts in some areas, and even generated lawsuits over mask mandates.
The issue presents an ongoing challenge for physicians as they strive to educate patients about the significance of masking against the flood of antimask messages on social media and beyond. Opposition to masks is particularly frustrating for health professionals who have witnessed patients, family, or friends become ill or die from the virus. Refusing to mask and failing to social distance have been linked to the rapid spread of the coronavirus and subsequent deaths.
“I have had colleagues pass away, and it’s extremely disheartening and frustrating to see science so easily disregarded,” Sonpal said. “Masks save lives and protect people and not wearing them is simply a lack of respect, not just for your fellow colleagues, but for a member of your species.”
Michael Rebresh, who helped create the antimask group Million Unmasked Patriots, says his group’s objections to masks are rational and reasonable. The group, which has more than 8,000 members, formed in response to guidance by Illinois state officials that children would only be allowed to return to school wearing a mask.
“Our objections are to the fact that masks on children in school have a greater propensity to make children sick from breathing in bacteria that forms on the inner layer of a mask worn for hours on end,” Rebresh said. “We have an objection to the increase of CO2 intake and a decrease in oxygen flow for kids who need all the oxygen they can get during a learning environment. We recognized the masking of ourselves and kids for what it is: A political move to separate the two parties in our November election and define and create division between the two.”
Million Unmasked Patriots is one of dozens of antimask groups on social media platforms such as Facebook, Instagram, and TikTok. In July, Facebook suspended one such group, Unmasking America, which boasts 9,600 members, for posting repeated claims that face masks obstruct oxygen flow and have negative mental health effects.
Experts say the antiscience rhetoric is far from new. The antimask movement in many ways, shares similarities with that of the anti-vaccine movement, says Todd Wolynn, MD, a Pittsburgh pediatrician and cofounder of Shots Heard Round the World, an organization that defends vaccine advocates against coordinated online attacks by antivaxxers.
“A lot of it is conspiracy-laden,” said Wolynn of the disinformation. “That Dr. [Anthony] Fauci somehow helped construct the pandemic and that it’s not real. That Bill Gates is funding the vaccine so he can inject people with microchips. All sorts of really out-there, ungrounded conspiracy theories. If you had Venn diagram of antimask and antivaxx, I would say there’s clearly overlap.”
Parallels between antimaskers, antivaxxers
Opponents to masks fall on a spectrum, explains Vineet Arora, MD, a hospitalist and associate chief medical officer–clinical learning environment at University of Chicago Medicine. People who believe conspiracy theories and push misinformation are on one end, she said. There are also those who generally don’t believe the seriousness of the pandemic, feel their risk is minimal, or doubt the benefits of masks.
The two trains of thought resemble the distinction among parents who are antivaccine and those who are simply “vaccine hesitant,” says Arora, who co-authored a recent article about masking and misinformation that addresses antivaccine attitudes.
“While the antimask sentiment gets a lot of attention, I think it’s important to highlight there’s a lot of vocal anti-mask sentiment since most people are supportive of masks,” she said. “There might be people sitting on the fence who are just unsure about wearing a mask. That’s understandable because the science and the communication has evolved. There was a lot of early mixed messages about masking. Anytime you have confusion about the science or the science is evolving, it’s easy to have misinformation and then have that take off as myth.”
Just as antivaxxers work to swing the opinion of the vaccine hesitant, antimaskers are vying with public health advocates for the support of the mask hesitant, she said. Creating doubt in public health authorities is one way they are gaining followers. Anti-maskers often question and scrutinize past messaging about masks by public health officials, claiming that because guidance on masks has changed over time, the science behind masks and current guidance can’t be trusted, Wolynn said. Similarly, antivaxxers frequently question past actions by public health officials, such as the Tuskegee Experiment (which began in 1932), to try to poke holes in the credibility of public health officials and their advice.
Both the antimask and antivaccine movements also tend to base their resistance on a personal liberties argument, adds Jacqueline Winfield Fincher, MD, president for the American College of Physicians and an internist based in Thomson, Georgia. Antimaskers contend they should be free to decide whether to wear face coverings and that rules requiring masks infringe upon their civil liberties. Similarly, antivaxxers argue they should be free to decide whether to vaccinate their children and contend vaccine mandates violate their personal liberties.
Taking a deeper look, fear and control are two likely drivers of antimasking and antivaccine attitudes, Fincher said. Those refusing to wear masks may feel they have no control over the pandemic or its impacts, but they can control how they respond to mask-wearing requirements, she said.
Antivaccine parents often want more control over their children’s healthcare and falsely believe that vaccines are injecting something harmful into their children or may lead to harmful reactions.
“It’s a control issue and a defense mechanism,” she said. “Some people may feel helpless to deal with the pandemic or believe since it is not affecting them or their family, that it is not real. ‘If I just deny it and I don’t acknowledge facts, I don’t have to worry about it or do anything about it, and therefore I will have more control over my day-to-day life.’”
Groups fueling each other
In some cases, antimask and antivaxx groups are joining forces or adopting dual causes.
In California for instance, longtime opponents to vaccines are now objecting to mask policies as similar infringement to their bodily autonomy. Demonstrations in Texas, Idaho, and Michigan against mask mandates and other COVID-19 requirements have drawn support from anti-vaccine activists and incorporated antivaccine propaganda.
In Illinois, Million Unmasked Patriots, formally the Million Unmasked March, has received widespread attention for protesting both masks for returning schoolchildren and a future COVID-19 vaccine requirement.
A July protest planned by the antimask group triggered a letter by Arora and 500 other healthcare professionals to Illinois lawmakers decrying the group’s views and urging the state to move forward with universal masking in schools.
“What’s happening is those who are distrustful of government and public health and science are joining together,” said Arora, who coauthored a piece about the problem on KevinMD.com. “It’s important to address both movements together because they can quickly feed off each other and build in momentum. At the heart of both is really this deep skepticism of science.”
Rebresh of Million Unmasked Patriots said most of his members are not opposed to all vaccines, but rather they are opposed to “untested vaccines.” The primary concern is the inability to research long-term effects of a COVID-19 vaccine before its approval, he said.
Rebresh disagrees with the antimask movement being compared with the antivaccine movement. The two groups are “motivated by different things and a different set of circumstances drive their opinions,” he said. However, Rebresh believes that potential harm resulting from “mass vaccinations” is a valid concern. For this reason, he and his wife chose for their children to receive their vaccinations individually over a series of weeks, rather than the “kiddie cocktail of vaccines,” at a single visit, he said.
Vaccine scientist Peter Hotez, MD, PhD, said the antivaccine movement appears to have grown stronger from the pandemic fueled by fresh conspiracies and new alliances. Antivaccine sentiment has been gaining steam over the last several years and collecting more allies from the far-right, said Hotez, dean for the National School of Tropical Medicine and codirector for the Texas Children’s Hospital Center for Vaccine Development.
“Now what you’re seeing is yet another expansion this year, with antivaccine groups, under the banner of ‘health freedom,’ campaigning against social distancing and wearing masks and contact tracing,” he said. “What was an antivaccine movement has now become a full-blown antiscience movement and an anti-public health movement. It’s causing a lot of damage and I believe costing a lot of American lives.”
Neil F. Johnson, PhD, who has studied the antivaccine movement and its social media proliferation during the pandemic, said online comments by antivaxxers frequently condemn mask usage and showcase memes making fun of masks.
“In those same narratives about opposing vaccines for COVID, we see a lot of discussion against masks,” said Johnson, a physics professor at George Washington University in Washington, D.C. “If you don’t believe in the official picture of COVID, you don’t believe the policies or the advice that’s given about COVID.”
An analysis by Johnson that examined 1,300 Facebook pages found that, while antivaxxers have fewer followers than provaccine pages, antivaccine pages are more numerous, faster growing, and are more often connected to unrelated, undecided pages. Conversely, pages that advocate the benefits of vaccinations and explain the science behind immunizations are largely disconnected from such undecided communities, according to the study, published May 13 in Nature.
The study suggests the antivaccine movement is making influential strides during the pandemic and connecting with people who are undecided, while public health advocates are not building the same bridges, Johnson said.
“I think it’s hugely dangerous, because I don’t know any other moment in science or in public health when there was so much uncertainty in something affecting everybody,” he said. “Every policy that will be coming, everything depends on people buying into the official message. Once you have the seeds of doubt, that’s a very difficult thing to overcome. It’s an unprecedented challenge.”
How physicians and clinicians can help
A more aggressive approach is necessary when it comes to taking down antiscience content on social media, says Hotez. Too often, misinformation and antiscience rhetoric is allowed to linger on popular sites such as Facebook and Amazon.
Wolynn agrees. On personal or business platforms, it’s crucial to ban, hide, and delete such comments as quickly as possible, he said. On public sites, purposeful disinformation should be immediately reported to the platform.
At the same time, Wolynn said it’s essential to support those who make sound, science-based comments in social media forums.
“If you see someone who is pushing accurate, evidence-based information, and they come under attack, they should be supported and defended and empowered,” Wolynn said. “Shots Heard Round the World is doing all of those things, including galvanizing and recruiting more people to help get their voices out there.”
Expanded visibility by physicians and scientists would greatly help counter the spread of antiscience sentiment, adds Hotez.
“Too often, antiscience movements are able to flourish because scientists and physicians are invisible,” he said. “They’re too focused on either clinical practices or in the case of physician scientists, on grants and papers and not enough attention to public engagement. We’re going to have to change that around. We need to hear more from scientists directly.”
To that end, Wolynn said health care professionals, including medical students and residents, need to have formal training in communications, media, and social media as part of their education – and more support from employers to engage through social media.
“That’s where the fight is,” Wolynn said. “You can be the best diagnostician, the best clinician. You can make the right diagnosis and prescribe the right medication, but if families don’t hear what you’re saying, you’re not going to be effective. If you can’t be on the platform where they’re being influenced, we’re losing the battle.”
Speaking to your mask-hesitant patients
Concentrating on those who are uncertain about masks is particularly key for physicians and public health advocates as the pandemic continues, says Arora.
“It’s important for us to focus on the mask-hesitant who often don’t get the attention they need,” she said.
She suggests bringing up the subject of masks with patients during visits, asking about mask usage, discussing rumors they’ve heard, and emphasizing why masks are important. Be a role model by wearing a mask in your community and on social media, she added.
Some patients have real concerns about not being able to breathe through masks or anxiety disorders that can be aggravated even by the thought of wearing a mask, noted Susan R. Bailey, MD, president for the American Medical Association. Bailey, an immunologist, recently counseled a patient with a deviated nasal septum in addition to a panic disorder who was worried about wearing a mask, she said. Bailey listened to the patient’s concerns, discussed his health conditions, and proposed an alternative face covering that might make him more comfortable.
“Every patient is different,” Bailey said. “It’s important for us to remember that each person who is reluctant to wear a mask has their own reasons. It’s important for us to express some empathy – to agree with them, yes, masks are hot and inconvenient – and help understand their questions, which you may be able to answer to their satisfaction. There are patients that have legitimate questions and a physician caring about how they feel, can make all the difference.”
Physicians can also get involved with the AMA’s #MaskUp campaign, an effort to normalize mask wearing and debunk myths associated with masks. The campaign includes social media materials, slogans doctors can tweet, and profile pictures they can use on social media. The campaign’s toolkit includes images, videos, and information that physicians can share with patients and the public.
Enforcing strong mask policies at your practice and ensuring all staff are modeling appropriate mask behavior is also important, adds Fincher of the ACP. The college recently issued a policy supporting mask usage in community settings.

U.S. tops 500,000 COVID-19 cases in children
according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
States have reported 513,415 cases of COVID-19 in children since the beginning of the pandemic, with almost 37,000 coming in the last week, the AAP and the CHA said Sept. 8 in the weekly report. That figure includes New York City – the rest of New York State is not reporting ages for COVID-19 patients – as well as Puerto Rico, the District of Columbia, and Guam.
“These numbers are a chilling reminder of why we need to take this virus seriously,” AAP President Sara Goza, MD, said in a written statement.
Children now represent 9.8% of the almost 5.3 million cases that have been reported in Americans of all ages. The proportion of child cases has continued to increase as the pandemic has progressed – it was 8.0% as of mid-July and 5.2% in early June, the data show.
“Throughout the summer, surges in the virus have occurred in Southern, Western, and Midwestern states,” the AAP statement said.
The latest AAP/CHA report shows that, from Aug. 27 to Sept. 3, the total number of child cases jumped by 33.7% in South Dakota, more than any other state. North Dakota was next at 22.7%, followed by Hawaii (18.1%), Missouri (16.8%), and Kentucky (16.4%).
“This rapid rise in positive cases occurred over the summer, and as the weather cools, we know people will spend more time indoors,” said Sean O’Leary, MD, MPH, vice chair of the AAP Committee on Infectious Diseases. “The goal is to get children back into schools for in-person learning, but in many communities, this is not possible as the virus spreads unchecked.”
The smallest increase over the last week, just 0.9%, came in Rhode Island, with Massachusetts just a bit higher at 1.0%. Also at the low end of the increase scale are Arizona (3.3%) and Louisiana (4.0%), two states that have very high rates of cumulative cases: 1,380 per 100,000 children for Arizona and 1,234 per 100,000 for Louisiana, the report said.
To give those figures some context, Tennessee has the highest cumulative count of any state at 1,553 cases per 100,000 children and Vermont has the lowest at 151, based on the data gathered by the AAP and CHA.
“While much remains unknown about COVID-19, we do know that the spread among children reflects what is happening in the broader communities. A disproportionate number of cases are reported in Black and Hispanic children and in places where there is high poverty. We must work harder to address societal inequities that contribute to these disparities,” Dr. Goza said.

Mounting data support COVID-19 acute pancreatitis
Mounting data support acute pancreatitis as one possible GI manifestation of COVID-19, according to investigators.
While previous case reports suggested that infection with SARS-CoV2 may lead to pancreatitis, this retrospective analysis, which is the largest to date, is the first to offer substantial evidence for this claim, reported lead author Sumant Inamdar, MBBS, of the University of Arkansas, Little Rock, and colleagues.
“It has become increasingly clear that COVID-19 has systemic effects that also includes the gastrointestinal and pancreaticobiliary systems,” the investigators wrote in Gastroenterology. “As islet cells of the pancreas contain ACE2 receptor proteins, SARS-CoV2 can bind to these receptors and cause pancreatic injury.”
For the present analysis, Dr. Inamdar and colleagues reviewed charts from 48,012 patients who were hospitalized in New York between March and June of this year. While pancreatitis is usually diagnosed based on two out of three criteria, disease classification in the study required all three: characteristic upper abdominal pain upon admission, lipase greater than three times the upper limit of normal, and evidence of pancreatitis on cross-sectional imaging.
“[B]y including all three criteria for pancreatitis in our definition, we may be underestimating the rate of pancreatitis,” the investigators wrote. “However, we felt including diagnostic lipase levels and imaging was important for the accuracy of the diagnosis.”
Primary outcomes included mechanical ventilation, length of stay, development of pancreatic necrosis, and mortality. Outcomes were compared between patients with and without COVID-19.
Out of 48,012 hospitalized patients, 11,883 (24.75%) tested positive for SARS-CoV2. Across the entire population, 189 patients had pancreatitis (0.39%), and of these, 32 (17%) also had COVID-19. This translates to a point prevalence for pancreatitis of 0.27% for patients hospitalized with COVID-19.
Among patients with pancreatitis who did not have COVID-19, the most common etiologies for pancreatitis were gallstones (34%) and alcohol (37%), compared with just 16% and 6% of SARS-CoV2-positive cases of pancreatitis, respectively. Idiopathic pancreatitis was significantly more common among patients with COVID-19 than those without (69% vs 21%; P less than .0001).
Black or Hispanic patients with pancreatitis were 4-5 times more likely to have COVID-19 than patients with pancreatitis who were white. Across all races/ethnicities, patients with pancreatitis and COVID-19 more often required mechanical ventilation (odds ratio [OR], 5.65) and longer hospital stays (OR, 3.22), compared with those who had pancreatitis alone. While rates of mortality and pancreatic necrosis showed similar trends, associations with COVID-19 were not statistically significant.
“These findings support the notion that pancreatitis should be included in the list of GI manifestations of COVID-19,” the investigators wrote.
When caring for patients with COVID-19, Dr. Inamdar and colleagues recommended that clinicians pay close attention to any history of abdominal pain, and consider testing serum lipase levels.
“Further large studies are needed to confirm our findings,” they concluded.
Gyanprakash Avinash Ketwaroo, MD, of Baylor College of Medicine in Houston, agreed that more work is needed; in the meantime, he suggested that evidence is now strong enough for clinicians to take notice.
“Overall, this study adds further weight to COVID-19 acute pancreatitis,” he said. “Larger studies, and convincing pathophysiologic data, will be needed to confirm COVID-19 as a cause of acute pancreatitis. However, there appears to be enough circumstantial evidence to consider a COVID-19 diagnosis in patients presenting with acute pancreatitis.”
He noted that the new clinical evidence also stands on a solid theoretical foundation.
“Viruses, especially mumps and measles, have long been known to cause acute pancreatitis,” he said. “Additionally, the ACE2 receptor is present on pancreatic beta-cells and may mediate COVID-19 induced pancreatitis.”
Along with larger observational studies, Dr. Ketwaroo suggested that a number of interventional questions remain unanswered.
“While most acute pancreatitis is treated with supportive care, could proven therapies for COVID-19, such as steroids, also mitigate COVID-19 acute pancreatitis?” he asked. “Is COVID-19 a cofactor for acute pancreatitis caused by alcohol or endoscopic retrograde cholangiopancreatography? We await further information from an active area of research.”
The investigators disclosed relationships with Boston Scientific, Olympus, Fujifilm, and others.

“[B]y including all three criteria for pancreatitis in our definition, we may be underestimating the rate of pancreatitis,” the investigators wrote. “However, we felt including diagnostic lipase levels and imaging was important for the accuracy of the diagnosis.”
Primary outcomes included mechanical ventilation, length of stay, development of pancreatic necrosis, and mortality. Outcomes were compared between patients with and without COVID-19.
Out of 48,012 hospitalized patients, 11,883 (24.75%) tested positive for SARS-CoV2. Across the entire population, 189 patients had pancreatitis (0.39%), and of these, 32 (17%) also had COVID-19. This translates to a point prevalence for pancreatitis of 0.27% for patients hospitalized with COVID-19.
Among patients with pancreatitis who did not have COVID-19, the most common etiologies for pancreatitis were gallstones (34%) and alcohol (37%), compared with just 16% and 6% of SARS-CoV2-positive cases of pancreatitis, respectively. Idiopathic pancreatitis was significantly more common among patients with COVID-19 than those without (69% vs 21%; P less than .0001).
Black or Hispanic patients with pancreatitis were 4-5 times more likely to have COVID-19 than patients with pancreatitis who were white. Across all races/ethnicities, patients with pancreatitis and COVID-19 more often required mechanical ventilation (odds ratio [OR], 5.65) and longer hospital stays (OR, 3.22), compared with those who had pancreatitis alone. While rates of mortality and pancreatic necrosis showed similar trends, associations with COVID-19 were not statistically significant.
“These findings support the notion that pancreatitis should be included in the list of GI manifestations of COVID-19,” the investigators wrote.
When caring for patients with COVID-19, Dr. Inamdar and colleagues recommended that clinicians pay close attention to any history of abdominal pain, and consider testing serum lipase levels.
“Further large studies are needed to confirm our findings,” they concluded.
Gyanprakash Avinash Ketwaroo, MD, of Baylor College of Medicine in Houston, agreed that more work is needed; in the meantime, he suggested that evidence is now strong enough for clinicians to take notice.
“Overall, this study adds further weight to COVID-19 acute pancreatitis,” he said. “Larger studies, and convincing pathophysiologic data, will be needed to confirm COVID-19 as a cause of acute pancreatitis. However, there appears to be enough circumstantial evidence to consider a COVID-19 diagnosis in patients presenting with acute pancreatitis.”
He noted that the new clinical evidence also stands on a solid theoretical foundation.
“Viruses, especially mumps and measles, have long been known to cause acute pancreatitis,” he said. “Additionally, the ACE2 receptor is present on pancreatic beta-cells and may mediate COVID-19 induced pancreatitis.”
Along with larger observational studies, Dr. Ketwaroo suggested that a number of interventional questions remain unanswered.
“While most acute pancreatitis is treated with supportive care, could proven therapies for COVID-19, such as steroids, also mitigate COVID-19 acute pancreatitis?” he asked. “Is COVID-19 a cofactor for acute pancreatitis caused by alcohol or endoscopic retrograde cholangiopancreatography? We await further information from an active area of research.”
The investigators disclosed relationships with Boston Scientific, Olympus, Fujifilm, and others.

Tools emerging to predict liver failure in cirrhosis
Systemic inflammation and portal hypertension are key predictors of acute-on-chronic liver failure (ACLF) in the 3 months after a hospital stay for acute decompensated cirrhosis and also of death after 12 months, a preliminary analysis of data from the PREDICT study shows.
“Before this, we never had any patient signatures to identify ACLF,” said Jonel Trebicka, MD, PhD, from the JW Goethe University Hospital in Frankfurt, Germany.
Now, Dr. Trebicka’s team has “characterized the phenotypes in pre-ACLF that will progress within 3 months,” he said in an interview. “Those with high levels of inflammatory proteins, white blood cell count, are more likely to develop ACLF.”
ACLF is a highly complex disorder that can lead liver, cardiovascular, renal, cerebral, pulmonary, intestinal, adrenal, and immune systems to fail, Dr. Trebicka explained when he discussed the analysis – published online in the Journal of Hepatology – during the virtual International Liver Congress (ILC) 2020.
The chance of survival after the onset of ACLF is low – the 28-day survival rate is 30% – and “the only treatment we have is liver transplant,” he said.
For their prospective observational study, Dr. Trebicka and his colleagues assessed 1071 participants from 48 European hospitals in 14 countries who were admitted for an episode of acute decompensation, defined as the development of ascites, hepatic encephalopathy, gastrointestinal hemorrhage, infection, or a combination thereof.
The researchers identified three distinct clinical courses for a patient hospitalized with acute decompensated cirrhosis that will help clinicians predict the development of ACLF.
At study enrollment, more than half of the patients at highest risk for ACLF had pre-ACLF and high-grade systemic inflammation. The patients at intermediate risk had unstable decompensated cirrhosis with low-grade systemic inflammation and complications related to severe portal hypertension. And those at lowest risk for ACLF had stable decompensated cirrhosis and no severe systemic inflammation or portal hypertension complications, and did not develop ACLF or another episode of acute decompensation in the subsequent 3 months.
“There have been hints of possible phenotypes before – for stable and unstable ACLF – but we never had anything specific to diagnose,” Trebicka reported.
“We found that there are two main mechanisms in the development of ACLF that are most important,” he said. The first is systemic inflammation with high levels of proteins, which “leads to organ failure. This is the most striking acute mechanism.”
The second is the development of portal hypertension. “This is slower, but also very important, causing increased pressure in the portal vein, and leading to bleeding if the pressure is too great,” he said.
More tools emerging to help predict ACLF
The Albumin-functionality-test (AFT), which uses serum albumin levels to evaluate liver and kidney function, might also be useful in the prediction of ACLF and 12-month survival, according to a separate study an Italian group presented at the virtual ILC.
“Our main results are that parameters from albumin predict the development of ACLF in acute decompensated patients with the same diagnostic performance as the CLIF-AD score,” said Katja Waterstradt, PhD, from the University of Bologna in Italy.
And when the two tests are combined, diagnostic performance is increased, she added.
Dr. Trebicka has disclosed no relevant financial relationships. Dr. Waterstrand is a researcher for MedInnovation GmbH.
