Infectious Diseases

Characteristics

The ubiquitous human flea, Pulex irritans, is a hematophagous wingless ectoparasite in the order Siphonaptera (wingless siphon) that survives by consuming the blood of its mammalian and avian hosts. Due to diseases such as the bubonic plague, fleas have claimed more victims than all the wars ever fought; in the 14th century, the Black Death caused more than 200 million deaths. Fleas fossilized in amber have been found to be 200 million years old and closely resemble the modern human flea, demonstrating the resilience of the species.

The adult human flea is a small, reddish brown, laterally compressed, wingless insect that is approximately 2- to 3.5-mm long (females, 2.5–3.5 mm; males, 2–2.5 mm) and enclosed by a tough cuticle. Compared to the dog flea (Ctenocephalides canis) and cat flea (Ctenocephalides felis), P irritans has no combs or ctenidia (Figure 1). Fleas have large powerful hind legs enabling them to jump horizontally or vertically 200 times their body length (equivalent to a 6-foot human jumping 1200 feet) using stored muscle energy in a pad on the hind legs composed of the elastic protein resilin.¹ They feed off a wide variety of hosts, including humans, pigs, cats, dogs, goats, sheep, cattle, chickens, owls, foxes, rabbits, mice, and feral cats. The flea’s mouthparts are highly specialized for piercing the skin and sucking its blood meal via direct capillary cannulation.

Life Cycle

There are 4 stages of the flea life cycle: egg, larva, pupa, and adult. Most adult flea species mate on the host; the female will lay an average of 4 to 8 small white eggs on the host after each blood meal, laying more than 400 eggs during her lifetime. The eggs then drop from the host and hatch in approximately 4 to 6 days to become larvae. The active larvae feed on available organic matter in their environment, such as their parents’ feces and detritus, while undergoing 3 molts within 1 week to several months.² The larva then spins a silken cocoon from modified salivary glands to form the pupa. In favorable conditions, the pupa lasts only a few weeks; however, it can last for a year or more in unfavorable conditions. Triggers for emergence of the adult flea from the pupa include high humidity, warm temperatures, increased levels of carbon dioxide, and vibrations including sound. An adult P irritans flea can live for a few weeks to more than 1.5 years in favorable conditions of lower air temperature, high relative humidity, and access to a host.³

Related Diseases

Pulex irritans can be a vector for several human diseases. Yersinia pestis is a gram-negative bacteria that causes plague, a highly virulent disease that killed millions of people during its 3 largest human pandemics. The black rat (Rattus rattus) and the oriental rat flea (Xenopsylla cheopis) have been implicated as initial vectors; however, transmission may be human-to-human with pneumonic plague, and septicemic plague may be spread via Pulex fleas or body lice.^4,5 In 1971, Y pestis was isolated from P irritans on a dog in the home of a plague patient in Kayenta, Arizona.⁶Yersinia pestis bacterial DNA also was extracted from P irritans during a plague outbreak in Madagascar in 2014⁷ and was implicated in epidemiologic studies of plague in Tanzania from 1986 to 2004, suggesting it also plays a role in endemic disease.⁸

Bartonellosis is an emerging disease caused by different species of the gram-negative intracellular bacteria of the genus Bartonella transmitted by lice, ticks, and fleas. Bartonella quintana causes trench fever primarily transmitted by the human body louse, Pediculus humanus corporis, and resulted in more than 1 million cases during World War I. Trench fever is characterized by headache, fever, dizziness, and shin pain that lasts 1 to 3 days and recurs in cycles every 4 to 6 days. Other clinical manifestations of B quintana include chronic bacteremia, endocarditis, lymphadenopathy, and bacillary angiomatosis.⁹Bartonella henselae causes cat scratch fever, characterized by lymphadenopathy, fever, headache, joint pain, and lethargy from infected cat scratches or the bite of an infected flea. Bartonella rochalimae also has been found to cause a trench fever–like bacteremia.¹⁰Bartonella species have been found in P irritans, and the flea is implicated as a vector of bartonellosis in humans.^11-15

Rickettsioses are worldwide diseases caused by the gram-negative intracellular bacteria of the genus Rickettsia transmitted to humans via hematophagous arthropods. The rickettsiae traditionally have been classified into the spotted fever or typhus groups. The spotted fever group (ie, Rocky Mountain spotted fever, Mediterranean spotted fever) is transmitted via ticks. The typhus group is transmitted via lice (epidemic typhus) and fleas (endemic or murine typhus). Murine typhus can be caused by Rickettsia typhi in warm coastal areas around the world where the main mammal reservoir is the rat and the rat flea vector X cheopis. Clinical signs of infection are abrupt onset of fever, headaches, myalgia, malaise, and chills, with a truncal maculopapular rash progressing peripherally several days after the initial clinical signs. Rash is present in up to 50% of cases.¹⁶Rickettsia felis is an emerging flea-borne pathogen causing an acute febrile illness usually transmitted via the cat flea C felis.¹⁷Rickettsia species DNA have been found to be present in P irritans from dogs¹⁸ and livestock¹⁹ and pose a risk for causing rickettsioses in humans.

Environmental Treatment and Prevention

Flea bites present as intense, pruritic, urticarial to vesicular papules that usually are located on the lower extremities but also can be present on exposed areas of the upper extremities and hands (Figure 2). Human fleas infest clothing, and bites can be widespread. Topical antipruritics and corticosteroids can be used for controlling itch and the intense cutaneous inflammatory response. The flea host should be identified in areas of the home, school, farm, work, or local environment. House pets should be examined and treated by a veterinarian. The pet’s bedding should be washed and dried at high temperatures, and carpets and floors should be routinely vacuumed or cleaned to remove eggs, larvae, flea feces, and/or pupae. The killing of adult fleas with insecticidal products (eg, imidacloprid, fipronil, spinosad, selamectin, lufenuron, ivermectin) is the primary method of flea control. Use of insect growth regulators such as pyriproxyfen inhibits adult reproduction and blocks the organogenesis of immature larval stages via hormonal or enzymatic actions.²⁰ The combination of an insecticide and an insect growth regulator appears to be most effective in their synergistic actions against adult fleas and larvae. There have been reports of insecticidal resistance in the flea population, especially with pyrethroids.^21,22 A professional exterminator and veterinarian should be consulted. In recalcitrant cases, evaluation for other wild mammals or birds should be performed in unoccupied areas of the home such as the attic, crawl spaces, and basements, as well as inside walls.

Conclusion

The human flea, P irritans, is an important vector in the transmission of human diseases such as the bubonic plague, bartonellosis, and rickettsioses. Flea bites present as intensely pruritic, urticarial to vesicular papules that most commonly present on the lower extremities. Flea bites can be treated with topical steroids, and fleas can be controlled by a combination of insecticidal products and insect growth regulators.

The age of antiretroviral therapy (ART) for HIV is in its third decade, and many of the patients who live in areas of the world fortunate enough to have had early access to therapy have now lived for several decades with complications of HIV and viral suppressive therapy.

But while the life-expectancy of persons with HIV has approached that of noninfected persons over the last 20 years, the higher burden of comorbidities for aging patients with HIV has remained largely the same, according to an epidemiologist who specializes in HIV/AIDS research and aging.

“The pathways from HIV and its treatments to comorbidities are very long and winding, spanning a life course. Social determinants of health and individual risk factors also play an important role, and must be considered,” said Keri N. Althoff, PhD, MPH, of Johns Hopkins University, Baltimore.

Dr. Althoff discussed long-term complications of HIV and its treatment in a virtual symposium during an annual scientific meeting on infectious diseases.

“Many urban HIV providers have an increased proportion of patients who are older long-term survivors of the epidemic. Many, but not all of the comorbidities (including cardiovascular, neurocognitive, renal, and malignancies) have been associated with age, long-term HIV infection, especially uncontrolled HIV infection, and low CD4 nadirs,” commented Harry Lampiris, MD, professor of clinical medicine at the University of California, San Francisco.

“An increasing number of patients are experiencing geriatric syndromes (especially problems with mobility, cognitive decline, food insecurity, polypharmacy, and social isolation) at younger ages than HIV-negative populations,” he added.

Dr. Lampiris, who moderated the session where Dr. Althoff presented her findings, commented on it in an interview, but was not involved in her research.
 

Pathways to comorbidity

The three primary pathways to comorbidities in people with HIV infections are as follows, according to Dr. Athloff:

• The virus itself, with its associated inflammation, immunosuppression, immune activation, and AIDS.
• HIV therapies, beginning with the notoriously toxic dideoxynucleoside analogues or “d-drugs,” and following with subsequent generations of newer, less toxic agents.
• Individual risk factors, including smoking, stress, diet, exercise, and environment.

Cardiovascular and renal complications

Persons with HIV have an approximately twofold higher risk for major adverse cardiovascular events (myocardial infarction, stroke) compared with persons without HIV. Conditions contributing to cardiovascular disease including hypertension, diabetes, and hyperlipidemia are also significantly higher among persons with HIV, Dr. Althoff said.

Hypertension among persons with HIV from the ages 60-69 years is especially high for Black men and to a lesser degree non-Black men, compared with either White or Black women, she noted.

Pathways to renal disease in persons with HIV include diabetes and hypertension, as well as therapies to treat them, hepatitis B and C coinfection, HIV-associated nephropathy, and immune complex kidney disease, as well as chronic kidney disease resulting from acute kidney injury related to therapy.

“Cardiovascular disease and kidney disease are excellent examples of why the life-course perspective is essential when caring for people with HIV. For those diagnosed with HIV at younger ages, there are points of intervention along the decades-long path, and the timing and implementation of the most effective intervention may preserve comorbidity-free years,” Dr. Althoff said.

Prevention and screening interventions to lower risk for future heart- and kidney-related comorbidities include smoking cessation and lifestyle optimization (diet, exercise, mental health), as well as lipid-lowering medications to lower risk for cardiovascular events.
 

Liver comorbidities

“Primary drivers of liver disease are social determinants of health and individual lifestyle risk factors that share the same pathways as HIV, resulting in this increased burden of liver disease in people with HIV,” she said.

Risk factors include alcoholic liver disease, nonalcoholic fatty liver disease, hepatitis B and C coinfection, drug use, autoimmune disease, and aging. These risk factors contribute to oxidative stress, mitochondrial injury, lipotoxicity, cytotoxicity, and other mechanisms that can lead to fibrosis, cirrhosis, hepatocellular carcinoma, and end-stage liver disease.

“I want to be sure to acknowledge the importance of liver disease as a comorbidity among people with HIV. Liver disease accounts for nearly 20% of mortality in persons with HIV,” she said.
 

Neurocognitive problems

HIV has been linked to neurocognitive decline since the beginning of the epidemic, Dr. Althoff noted. The term HIV-associated neurocognitive disorders encompasses the broad spectrum of cognitive effects of HIV, from asymptomatic illness to AIDS-related dementia. Estimates of cognitive impairment in people with HIV range from 14% to 64% across various study populations, but diagnosing and treating it in the community can be challenging.

“Routine monitoring of cognition is often just out of reach in the clinical setting, due to the time it takes to use validated tools. We need a deeper toolbox of quick and validated tools calibrated to people with HIV in order to accurately monitor cognition,” she said.

She noted that the average age of onset of Alzheimer’s disease in the general population is 80 years, and that relatively few people with HIV infection have reached that age.

“But before the population age distribution shifts to the older ages, we can do more to monitor cognition in people with HIV,” she added.

In addition to HIV, factors that can contribute to worse neurocognitive outcomes include major depressive disorder, occurring in and estimated 20%-40% of adults with HIV versus 8% of the U.S. population, generalized anxiety disorder (10%-25% vs. 3%), bipolar disorder (3%-9% vs. 3%), schizophrenia (4%-15% vs. 1%), and posttraumatic stress disorder (10%-30% vs. 8%).

Substance use and polypharmacy, common among adults with HIV, can also contribute to cognitive decline, she said.
 

Decreased mobility

The Multicenter AIDS Cohort Study (MACS) showed that decreased mobility, defined as a gait speed less than 1 m/sec, occurred earlier in life among HIV-positive men than in HIV-negative men.

In the general aging population, slow gait speed is a predictor for lower extremity limitations, hospitalization, and death, and in more recent MACS studies was associated with increased hemoglobin A_1C levels, as well as neurocognitive impairment.

“Hemoglobin A_1C is an intervenable target, and perhaps it will help to slow the decline in gait speed,” Dr. Althoff said.
 

Reduce ‘healthspan’ disparities

The goal for treating aging adults with HIV “is to reduce the disparity in healthspan between people with HIV compared to people without HIV by delaying or eliminating the onset of comorbidities among people with HIV,” she said.

The gerontological concept of extending “healthspan” – the duration of life without significant comorbidities – is to target common mechanisms of aging, thereby delaying the onset of more than one age-related disease at the same time.

“Crude translation of this concept to the population of aging with HIV includes reducing that gap in comorbidity-free survival in people with versus without HIV,” she said.

Modification of care models from geriatrics may help infectious disease specialists manage adults with HIV who have increasingly complex needs.

For example, the geriatric “5 M” model emphasizes focusing on issues of mind (mentation, dementia, delirium, depression), mobility (impaired gait and balance, as well as fall prevention), medications (reducing polypharmacy, optimal prescribing), multicomplexity (multiple morbidities and complex bio-psycho-social situations), and “matters most” (each patient’s individual meaningful health outcome goals and care preferences).

Changing exposures that may influence the pattern of comorbidities for patients with HIV in the future include earlier start on ART, shorter duration of uncontrolled viremia, compared with older populations, newer and less toxic ARTs, long-term viral suppression, and risk factor interventions, Dr. Althoff concluded.

Dr. Lampiris noted that “patients who have initiated therapy in the last 5-10 years are more likely to initiate antiretroviral therapy at higher CD4 counts, and less likely to experience long-term toxicities of antiretroviral therapy. However, African Americans, Hispanics and HIV-positive women continue to lag behind others with regard to timely initiation of treatment.

“In addition there are toxicities associated with the newer agents, particularly weight gain, which disproportionately affect African Americans and women and which may be made worse by poverty, food insecurity, and other health-related behaviors.”

Dr. Athloff’s work is supported by grants from the National Institutes for Health. She disclosed serving as a consultant to the NIH-funded All of US study and to MediQ, and as an adviser to TrioHealth. Dr. Lampiris reported having no disclosures.

The term HIV-associated neurocognitive disorders encompasses the broad spectrum of cognitive effects of HIV, from asymptomatic illness to AIDS-related dementia. Estimates of cognitive impairment in people with HIV range from 14% to 64% across various study populations, but diagnosing and treating it in the community can be challenging.

“Routine monitoring of cognition is often just out of reach in the clinical setting, due to the time it takes to use validated tools. We need a deeper toolbox of quick and validated tools calibrated to people with HIV in order to accurately monitor cognition,” she said.

She noted that the average age of onset of Alzheimer’s disease in the general population is 80 years, and that relatively few people with HIV infection have reached that age.

“But before the population age distribution shifts to the older ages, we can do more to monitor cognition in people with HIV,” she added.

In addition to HIV, factors that can contribute to worse neurocognitive outcomes include major depressive disorder, occurring in and estimated 20%-40% of adults with HIV versus 8% of the U.S. population, generalized anxiety disorder (10%-25% vs. 3%), bipolar disorder (3%-9% vs. 3%), schizophrenia (4%-15% vs. 1%), and posttraumatic stress disorder (10%-30% vs. 8%).

Substance use and polypharmacy, common among adults with HIV, can also contribute to cognitive decline, she said.
 

Decreased mobility

The Multicenter AIDS Cohort Study (MACS) showed that decreased mobility, defined as a gait speed less than 1 m/sec, occurred earlier in life among HIV-positive men than in HIV-negative men.

In the general aging population, slow gait speed is a predictor for lower extremity limitations, hospitalization, and death, and in more recent MACS studies was associated with increased hemoglobin A_1C levels, as well as neurocognitive impairment.

“Hemoglobin A_1C is an intervenable target, and perhaps it will help to slow the decline in gait speed,” Dr. Althoff said.
 

Reduce ‘healthspan’ disparities

The goal for treating aging adults with HIV “is to reduce the disparity in healthspan between people with HIV compared to people without HIV by delaying or eliminating the onset of comorbidities among people with HIV,” she said.

The gerontological concept of extending “healthspan” – the duration of life without significant comorbidities – is to target common mechanisms of aging, thereby delaying the onset of more than one age-related disease at the same time.

“Crude translation of this concept to the population of aging with HIV includes reducing that gap in comorbidity-free survival in people with versus without HIV,” she said.

Modification of care models from geriatrics may help infectious disease specialists manage adults with HIV who have increasingly complex needs.

For example, the geriatric “5 M” model emphasizes focusing on issues of mind (mentation, dementia, delirium, depression), mobility (impaired gait and balance, as well as fall prevention), medications (reducing polypharmacy, optimal prescribing), multicomplexity (multiple morbidities and complex bio-psycho-social situations), and “matters most” (each patient’s individual meaningful health outcome goals and care preferences).

Changing exposures that may influence the pattern of comorbidities for patients with HIV in the future include earlier start on ART, shorter duration of uncontrolled viremia, compared with older populations, newer and less toxic ARTs, long-term viral suppression, and risk factor interventions, Dr. Althoff concluded.

Dr. Lampiris noted that “patients who have initiated therapy in the last 5-10 years are more likely to initiate antiretroviral therapy at higher CD4 counts, and less likely to experience long-term toxicities of antiretroviral therapy. However, African Americans, Hispanics and HIV-positive women continue to lag behind others with regard to timely initiation of treatment.

“In addition there are toxicities associated with the newer agents, particularly weight gain, which disproportionately affect African Americans and women and which may be made worse by poverty, food insecurity, and other health-related behaviors.”

Dr. Athloff’s work is supported by grants from the National Institutes for Health. She disclosed serving as a consultant to the NIH-funded All of US study and to MediQ, and as an adviser to TrioHealth. Dr. Lampiris reported having no disclosures.

The age of antiretroviral therapy (ART) for HIV is in its third decade, and many of the patients who live in areas of the world fortunate enough to have had early access to therapy have now lived for several decades with complications of HIV and viral suppressive therapy.

But while the life-expectancy of persons with HIV has approached that of noninfected persons over the last 20 years, the higher burden of comorbidities for aging patients with HIV has remained largely the same, according to an epidemiologist who specializes in HIV/AIDS research and aging.

“The pathways from HIV and its treatments to comorbidities are very long and winding, spanning a life course. Social determinants of health and individual risk factors also play an important role, and must be considered,” said Keri N. Althoff, PhD, MPH, of Johns Hopkins University, Baltimore.

Dr. Althoff discussed long-term complications of HIV and its treatment in a virtual symposium during an annual scientific meeting on infectious diseases.

“Many urban HIV providers have an increased proportion of patients who are older long-term survivors of the epidemic. Many, but not all of the comorbidities (including cardiovascular, neurocognitive, renal, and malignancies) have been associated with age, long-term HIV infection, especially uncontrolled HIV infection, and low CD4 nadirs,” commented Harry Lampiris, MD, professor of clinical medicine at the University of California, San Francisco.

“An increasing number of patients are experiencing geriatric syndromes (especially problems with mobility, cognitive decline, food insecurity, polypharmacy, and social isolation) at younger ages than HIV-negative populations,” he added.

Dr. Lampiris, who moderated the session where Dr. Althoff presented her findings, commented on it in an interview, but was not involved in her research.
 

Pathways to comorbidity

The three primary pathways to comorbidities in people with HIV infections are as follows, according to Dr. Athloff:

• The virus itself, with its associated inflammation, immunosuppression, immune activation, and AIDS.
• HIV therapies, beginning with the notoriously toxic dideoxynucleoside analogues or “d-drugs,” and following with subsequent generations of newer, less toxic agents.
• Individual risk factors, including smoking, stress, diet, exercise, and environment.

Cardiovascular and renal complications

Persons with HIV have an approximately twofold higher risk for major adverse cardiovascular events (myocardial infarction, stroke) compared with persons without HIV. Conditions contributing to cardiovascular disease including hypertension, diabetes, and hyperlipidemia are also significantly higher among persons with HIV, Dr. Althoff said.

Hypertension among persons with HIV from the ages 60-69 years is especially high for Black men and to a lesser degree non-Black men, compared with either White or Black women, she noted.

Pathways to renal disease in persons with HIV include diabetes and hypertension, as well as therapies to treat them, hepatitis B and C coinfection, HIV-associated nephropathy, and immune complex kidney disease, as well as chronic kidney disease resulting from acute kidney injury related to therapy.

“Cardiovascular disease and kidney disease are excellent examples of why the life-course perspective is essential when caring for people with HIV. For those diagnosed with HIV at younger ages, there are points of intervention along the decades-long path, and the timing and implementation of the most effective intervention may preserve comorbidity-free years,” Dr. Althoff said.

Prevention and screening interventions to lower risk for future heart- and kidney-related comorbidities include smoking cessation and lifestyle optimization (diet, exercise, mental health), as well as lipid-lowering medications to lower risk for cardiovascular events.
 

Liver comorbidities

“Primary drivers of liver disease are social determinants of health and individual lifestyle risk factors that share the same pathways as HIV, resulting in this increased burden of liver disease in people with HIV,” she said.

Risk factors include alcoholic liver disease, nonalcoholic fatty liver disease, hepatitis B and C coinfection, drug use, autoimmune disease, and aging. These risk factors contribute to oxidative stress, mitochondrial injury, lipotoxicity, cytotoxicity, and other mechanisms that can lead to fibrosis, cirrhosis, hepatocellular carcinoma, and end-stage liver disease.

“I want to be sure to acknowledge the importance of liver disease as a comorbidity among people with HIV. Liver disease accounts for nearly 20% of mortality in persons with HIV,” she said.

HIV has been linked to neurocognitive decline since the beginning of the epidemic, Dr. Althoff noted. The term HIV-associated neurocognitive disorders encompasses the broad spectrum of cognitive effects of HIV, from asymptomatic illness to AIDS-related dementia.

A smartphone app that combines passively collected physiologic data from wearable devices, such as fitness trackers, and self-reported symptoms can discriminate between COVID-19–positive and –negative individuals among those who report symptoms, new data suggest.

After analyzing data from more than 30,000 participants, researchers from the Digital Engagement and Tracking for Early Control and Treatment (DETECT) study concluded that adding individual changes in sensor data improves models based on symptoms alone for differentiating symptomatic persons who are COVID-19 positive and symptomatic persons who are COVID-19 negative.

The combination can potentially identify infection clusters before wider community spread occurs, Giorgio Quer, PhD, and colleagues report in an article published online Oct. 29 in Nature Medicine. DETECT investigators note that marrying participant-reported symptoms with personal sensor data, such as deviation from normal sleep duration and resting heart rate, resulted in an area under the curve (AUC) of 0.80 (interquartile range [IQR], 0.73-0.86) for differentiating between symptomatic individuals who were positive and those who were negative for COVID-19.

“By better characterizing each individual’s unique baseline, you can then identify changes that may indicate that someone has a viral illness,” said Dr. Quer, director of artificial intelligence at Scripps Research Translational Institute in La Jolla, Calif. “In previous research, we found that the proportion of individuals with elevated resting heart rate and sleep duration compared with their normal could significantly improve real-time detection of influenza-like illness rates at the state level,” he said in an interview.

Thus, continuous passively captured data may be a useful adjunct to bricks-and-mortar site testing, which is generally a one-off or infrequent sampling assay and is not always easily accessible, he added. Furthermore, traditional screening with temperature and symptom reporting is inadequate. An elevation in temperature is not as common as frequently believed for people who test positive for COVID-19, Dr. Quer continued. “Early identification via sensor variables of those who are presymptomatic or even asymptomatic would be especially valuable, as people may potentially be infectious during this period, and early detection is the ultimate goal,” Dr. Quer said.

According to his group, adding these physiologic changes from baseline values significantly outperformed detection (P < .01) using a British model described in an earlier study by by Cristina Menni, PhD, and associates. That method, in which symptoms were considered alone, yielded an AUC of 0.71 (IQR, 0.63-0.79).

According to Dr. Quer, one in five Americans currently wear an electronic device. “If we could enroll even a small percentage of these individuals, we’d be able to potentially identify clusters before they have the opportunity to spread,” he said.
 

DETECT study details

During the period March 15 to June 7, 2020, the study enrolled 30,529 participants from all 50 states. They ranged in age from younger than 35 years (23.1%) to older than 65 years (12.8%); the majority (63.5%) were aged 35-65 years, and 62% were women. Sensor devices in use by the cohort included Fitbit activity trackers (78.4%) and Apple HealthKit (31.2%).

Participants downloaded an app called MyDataHelps, which collects smartwatch and activity tracker information, including self-reported symptoms and diagnostic testing results. The app also monitors changes from baseline in resting heart rate, sleep duration, and physical activity, as measured by steps.

Overall, 3,811 participants reported having at least one symptom of some kind (e.g., fatigue, cough, dyspnea, loss of taste or smell). Of these, 54 reported testing positive for COVID-19, and 279 reported testing negative.

Sleep and activity were significantly different for the positive and negative groups, with an AUC of 0.68 (IQR, 0.57-0.79) for the sleep metric and 0.69 (IQR, 0.61-0.77) for the activity metric, suggesting that these parameters were more affected in COVID-19–positive participants.

When the investigators combined resting heart rate, sleep, and activity into a single metric, predictive performance improved to an AUC of 0.72 (IQR, 0.64-0.80).

The next step, Dr. Quer said, is to include an alert to notify users of possible infection.
 

Alerting users to possible COVID-19 infection

In a similar study, an alert feature was already incorporated. The study, led by Michael P. Snyder, PhD, director of the Center for Genomics and Personalized Medicine at Stanford (Calif.) University, will soon be published online in Nature Biomedical Engineering. In that study, presymptomatic detection of COVID-19 was achieved in more than 80% of participants using resting heart rate.

“The median is 4 days prior to symptom formation,” Dr. Snyder said in an interview. “We have an alarm system to notify people when their heart rate is elevated. So a positive signal from a smartwatch can be used to follow up by polymerase chain reaction [testing].”

Dr. Snyder said these approaches offer a roadmap to containing widespread infections. “Public health authorities need to be open to these technologies and begin incorporating them into their tracking,” he said. “Right now, people do temperature checks, which are of limited value. Resting heart rate is much better information.”

Although the DETECT researchers have not yet received feedback on their results, they believe public health authorities could recommend the use of such apps. “These are devices that people routinely wear for tracking their fitness and sleep, so it would be relatively easy to use the data for viral illness tracking,” said co–lead author Jennifer Radin, PhD, an epidemiologist at Scripps. “Testing resources are still limited and don’t allow for routine serial testing of individuals who may be asymptomatic or presymptomatic. Wearables can offer a different way to routinely monitor and screen people for changes in their data that may indicate COVID-19.”

The marshaling of data through consumer digital platforms to fight the coronavirus is gaining ground. New York State and New Jersey are already embracing smartphone apps to alert individuals to possible exposure to the virus.

More than 710,000 New Yorkers have downloaded the COVID NY Alert app, launched in October to help protect individuals and communities from COVID-19 by sending alerts without compromising privacy or personal information. “Upon receiving a notification about a potential exposure, users are then able to self-quarantine, get tested, and reduce the potential exposure risk to family, friends, coworkers, and others,” Jonah Bruno, a spokesperson for the New York State Department of Health, said in an interview.

And recently the Mayo Clinic and Safe Health Systems launched a platform to store COVID-19 testing and vaccination data.

Both the Scripps and Stanford platforms are part of a global technologic response to the COVID-19 pandemic. Prospective studies, led by device manufacturers and academic institutions, allow individuals to voluntarily share sensor and clinical data to address the crisis. Similar approaches have been used to track COVID-19 in large populations in Germany via the Corona Data Donation app.

The study by Dr. Quer and colleagues was funded by a grant from the National Center for Advancing Translational Sciences at the National Institutes of Health. One coauthor reported grants from Janssen and personal fees from Otsuka and Livongo outside of the submitted work. The other authors have disclosed no relevant financial relationships. Dr. Snyder has ties to Personalis, Qbio, January, SensOmics, Protos, Mirvie, and Oralome.

Black patients may be significantly less likely to receive eradication testing after treatment for Helicobacter pylori infection than patients of other races/ethnic groups, based on a retrospective analysis of more than 1,700 individuals.

This disparity may exacerbate the already increased burden of H. pylori infection and gastric cancer among Black individuals, according to principal author David A. Leiman, MD, MSHP, of Duke University Medical Center in Durham, N.C.

“H. pylori infection disproportionately affects racial/ethnic minorities and those of lower socioeconomic status,” Dr. Leiman, coauthor Julius Wilder, MD, PhD, of Duke University in Durham, and colleagues wrote in their abstract presented at the annual meeting of the American College of Gastroenterology. “ACG guidelines recommend treatment for H. pylori infection followed by confirmation of cure. Adherence to these recommendations varies and its impact on practice patterns is unclear. This study characterizes the management of H. pylori infection and predictors of guideline adherence.”

The investigators analyzed electronic medical records from 1,711 patients diagnosed with H. pylori infection through the Duke University Health System between June 2016 and June 2018, most often (71%) via serum antibody test. Approximately two-thirds of those diagnosed were non-White (66%) and female (63%). Out of 1,711 patients, 622 (36%) underwent eradication testing, of whom 559 (90%) were cured.

Despite publication of the ACG H. pylori guideline midway through the study (February 2017), testing rates dropped significantly from 43.1% in 2016 to 35.9% in 2017, and finally 25.5% in 2018 (P < .0001).

“These findings are consistent with other work that has shown low rates of testing to confirm cure in patients treated for H. pylori,” Dr. Leiman said. “There remains a disappointingly low number of patients who are tested for cure.”

Across the entire study period, patients were significantly more likely to undergo eradication testing if they were treated in the gastroenterology department (52.4%), compared with rates ranging from 33% to 34.6% for internal medicine, family medicine, and other departments (P < .001).

Across all departments, Black patients underwent eradication testing significantly less often than patients of other races/ethnicities, at a rate of 30.5% versus 32.2% for White patients, 35.1% for Asian patients, and 36.7% for patients who were of other backgrounds (P < .001). Compared with White patients, Black patients were 38% less likely to undergo eradication testing (odds ratio, 0.62; 95% confidence interval, 0.48-0.79).

Dr. Leiman noted that these findings contrast with a study by Dr. Shria Kumar and colleagues from earlier this year, which found no racial disparity in eradication testing within a Veterans Health Affairs cohort.

“Black patients are significantly less likely to undergo testing for eradication than [patients of other races/ethnicities],” Dr. Leiman said. “More work is needed to understand the mechanisms driving this disparity.” He suggested a number of possible contributing factors, including provider knowledge gaps, fragmented care, and social determinants of health.

“It is clear that a greater emphasis on characterizing and addressing the social determinants of health, including poverty, education, and location, are needed,” Dr. Leiman said. “Although health systems are not solely responsible for the known and ongoing observations of disparities in care, interventions must be identified and implemented to mitigate these issues.” Such interventions would likely require broad participation, he said, including policy makers, health systems, and individual practitioners.

“We plan to perform a prospective mixed methods study to contextualize which social determinants are associated with a decreased likelihood of receiving appropriate eradication testing by exploring barriers at patient, practitioner, and health-system levels,” Dr. Leiman said. “Ultimately, we aim to leverage these findings to develop an evidence-based intervention to circumnavigate those identified barriers, thereby eliminating the observed disparities in H. pylori care.”

According to Gregory L. Hall, MD, of Northeast Ohio Medical University, Rootstown, and Case Western Reserve University, Cleveland, and codirector of the Partnership for Urban Health Research, Atlanta, the higher rate of H. pylori infection in Black individuals may stem partly from genetic factors.

“Studies have shown that African Americans with a higher proportion of African ancestry have higher rates of H. pylori, suggesting a genetic component to this increased risk,” he said.

Still, Dr. Hall, who is the author of the book Patient-Centered Clinical Care for African Americans, went on to emphasize appropriate H. pylori management and recognition of racial disparities in medicine.

“The ability to test for, treat, and confirm eradication of H. pylori infections represents a great opportunity to improve quality of life through decreased gastritis, gastric ulcers, and gastric cancer,” he said. “[The present findings] show yet another disparity in our clinical care of African Americans that needs increased awareness among providers to these communities.”

Rotonya Carr, MD, of the Hospital of the University of Pennsylvania, Philadelphia, and lead author of a recent publication addressing racism and health disparities in gastroenterology, said the findings of the present study add weight to a known equity gap.

“These data are concerning in view of the twofold higher prevalence of H. pylori seropositivity and twofold higher incidence of gastric cancer in Black patients, compared with White patients,” Dr. Carr said. “These and other data support a comprehensive approach to reduce GI disparities that includes targeted education of both GI specialists and referring providers.”

According to Dr. Leiman, individual practitioners may work toward more equitable outcomes through a comprehensive clinical approach, regardless of patient race or ethnicity.

“Clinicians should consider H. pylori therapy an episode of care that spans diagnosis, treatment, and confirmation of cure,” he said. “Closing the loop in that episode by ensuring eradication is vital to conforming with best practices, and to reduce patients’ long-term risks.”The investigators disclosed relationships with Exact Sciences, Guardant Health, and Phathom Pharmaceuticals. Dr. Hall and Dr. Carr reported no relevant conflicts of interest.

On December 31, 2019, cases of a severe pneumonia in patients in Wuhan, Hubei Province, China, were reported to the World Health Organization.^1,2 The novel coronavirus—severe acute respiratory syndrome coronavirus 2—was identified, and the coronavirus disease 2019 (COVID-19) became a public health emergency of international concern.¹ In March 2020, the World Health Organization officially characterized COVID-19 as a pandemic.³ As of October 2020, more than 42.3 million cases and 1.1 million deaths from COVID-19 have been confirmed worldwide.⁴

As more understanding of severe acute respiratory syndrome coronavirus 2 develops, various cutaneous manifestations of COVID-19 are being uncovered.⁵ The most common cutaneous manifestations of COVID-19 reported in the literature are maculopapular or morbilliform exanthem (36.1% of cutaneous manifestations), papulovesicular rash (34.7%), painful acral red purple papules (15.3%), urticaria (9.7%), livedo reticularis lesions (2.8%), and petechiae (1.4%).⁵

Interestingly, a series of unique cases was identified in April 2020 by a group of dermatologists in Spain. Most patients were children (median age, 13 years) or young adults (median age, 31 years; average age, 36 years; adult age range, 18–91 years).¹ Reporting on a representative sample of 6 patients in that series, the group noted that lesions, initially reddish, papular, and resembling chilblains (pernio), progressively became purpuric and flattened in the course of 1 week. Although the lesions presented with some referred discomfort or pain with palpation, they were not highly symptomatic, and no signs of ischemia or Raynaud syndrome were identified. Over time, lesions self-resolved without intervention. Most patients also did not present with what are considered classic COVID-19 signs or symptoms. Only the oldest patient (aged 91 years) presented with a notable respiratory condition; the remaining patients generally were in good health.¹ Dermatologists in Italy, France, and the United States also have witnessed these COVID-19–associated cutaneous manifestations.

Scientific understanding of COVID-19 and its associated dermatologic symptoms is evolving. Attention has turned to social media to inform and provide possible health solutions during this unprecedented medical crisis.⁶ Strict physical distancing measures have made patients and providers alike reliant on global digital social networks, such as Instagram, Twitter, and Facebook, to facilitate information sharing about COVID-19.⁷ The abundance of nonexpert advice and misinformation on social media makes communication of unbiased expert information difficult.^8,9 Furthermore, there is a need for dermatologists to provide medical information to patients regarding COVID-19, such as dermatologic manifestations, and clear guidance on immunobiologic or systemic medications during this unprecedented time.⁹

In recent years, dermatologists have established a growing presence on social media, with many recognized as social media influencers with the ability to affect patients’ health-related behavior.¹⁰ Social media frequently has been used by patients to solicit advice regarding skin concerns.^9,10 Many individuals, in fact, never see a physician after consulting social media for medical concerns or professional advice.⁹

In addition, as of March 2020, more than 61% of health care workers were found to use social media as a source of COVID-19–related information.¹¹ Therefore, dermatologists should utilize social media as a platform to share evidence-based information with the public and other health care workers.

Through social media, dermatologists can post high-quality images with clear descriptions to fully characterize skin manifestations in patients with COVID-19. The process of capturing and posting images to the virtual world using a smartphone allows practitioners to gain advice from peers and consultants, share findings with colleagues, and inform the public.¹² Social media posts of many deidentified clinical images of rashes in COVID-19–infected patients already have enabled rapid recognition of skin signs by dermatologists.¹³

Social media sites also are resources where organizations can post updated, evidence-based findings from academic journals. For example, the American Academy of Dermatology and its official journal, the Journal of the American Academy of Dermatology, had more than 22,000 and 27,000 Instagram followers, respectively, as of a March 2020 analysis.¹⁴ Recent online forums and social media posts contain accessible, graphical, patient-friendly images and information on evidence-based treatments for skin disease during the COVID-19 pandemic.¹³

We should consider initiatives that empower dermatologists to use social media to post unbiased, evidence-based information regarding manifestations of COVID-19 and guidelines for treatment of skin disease during this medical crisis. We hope that dermatologists will help lead the global response to the COVID-19 pandemic and contribute to the evolving knowledge base by characterizing COVID-19–related rashes, understanding their implications, and determining the best evidence for treatment.

There were more new cases of COVID-19 reported in children during the week ending Oct. 29 than any other week during the pandemic, the American Academy of Pediatrics announced Nov. 2.

For the week, over 61,000 cases were reported in children, bringing the number of COVID-19 cases for the month of October to nearly 200,000 and the total since the start of the pandemic to over 853,000, the AAP and the Children’s Hospital Association said in their weekly report.

“These numbers reflect a disturbing increase in cases throughout most of the United States in all populations, especially among young adults,” Yvonne Maldonado, MD, chair of the AAP Committee on Infectious Diseases, said in a separate statement. “We are entering a heightened wave of infections around the country. We would encourage family holiday gatherings to be avoided if possible, especially if there are high-risk individuals in the household.”

For the week ending Oct. 29, children represented 13.3% of all cases, possibly constituting a minitrend of stability over the past 3 weeks. For the full length of the pandemic, 11.1% of all COVID-19 cases have occurred in children, although severe illness is much less common: 1.7% of all hospitalizations (data from 24 states and New York City) and 0.06% of all deaths (data from 42 states and New York City), the AAP and CHA report said.

Other data show that 1,134 per 100,000 children in the United States have been infected by the coronavirus, up from 1,053 the previous week, with state rates ranging from 221 per 100,000 in Vermont to 3,321 in North Dakota. In Wyoming, 25.5% of all COVID-19 cases have occurred in children, the highest of any state, while New Jersey has the lowest rate at 4.9%, the AAP/CHA report showed.

In the 10 states making testing data available, children represent the lowest percentage of tests in Iowa (5.0%) and the highest in Indiana (16.9%). Iowa, however, has the highest positivity rate for children at 14.6%, along with Nevada, while West Virginia has the lowest at 3.6%, the AAP and CHA said in the report.

These numbers, however, may not be telling the whole story. “The number of reported COVID-19 cases in children is likely an undercount because children’s symptoms are often mild and they may not be tested for every illness,” the AAP said in its statement.

“We urge policy makers to listen to doctors and public health experts rather than level baseless accusations against them. Physicians, nurses and other health care professionals have put their lives on the line to protect our communities. We can all do our part to protect them, and our communities, by wearing masks, practicing physical distancing, and getting our flu immunizations,” AAP President Sally Goza, MD, said in the AAP statement.

For the week, over 61,000 cases were reported in children, bringing the number of COVID-19 cases for the month of October to nearly 200,000 and the total since the start of the pandemic to over 853,000, the AAP and the Children’s Hospital Association said in their weekly report.

“These numbers reflect a disturbing increase in cases throughout most of the United States in all populations, especially among young adults,” Yvonne Maldonado, MD, chair of the AAP Committee on Infectious Diseases, said in a separate statement. “We are entering a heightened wave of infections around the country. We would encourage family holiday gatherings to be avoided if possible, especially if there are high-risk individuals in the household.”

For the week ending Oct. 29, children represented 13.3% of all cases, possibly constituting a minitrend of stability over the past 3 weeks. For the full length of the pandemic, 11.1% of all COVID-19 cases have occurred in children, although severe illness is much less common: 1.7% of all hospitalizations (data from 24 states and New York City) and 0.06% of all deaths (data from 42 states and New York City), the AAP and CHA report said.

Other data show that 1,134 per 100,000 children in the United States have been infected by the coronavirus, up from 1,053 the previous week, with state rates ranging from 221 per 100,000 in Vermont to 3,321 in North Dakota. In Wyoming, 25.5% of all COVID-19 cases have occurred in children, the highest of any state, while New Jersey has the lowest rate at 4.9%, the AAP/CHA report showed.

In the 10 states making testing data available, children represent the lowest percentage of tests in Iowa (5.0%) and the highest in Indiana (16.9%). Iowa, however, has the highest positivity rate for children at 14.6%, along with Nevada, while West Virginia has the lowest at 3.6%, the AAP and CHA said in the report.

These numbers, however, may not be telling the whole story. “The number of reported COVID-19 cases in children is likely an undercount because children’s symptoms are often mild and they may not be tested for every illness,” the AAP said in its statement.

“We urge policy makers to listen to doctors and public health experts rather than level baseless accusations against them. Physicians, nurses and other health care professionals have put their lives on the line to protect our communities. We can all do our part to protect them, and our communities, by wearing masks, practicing physical distancing, and getting our flu immunizations,” AAP President Sally Goza, MD, said in the AAP statement.

The Food and Drug Administration has approved 0.5% lotion formulation of ivermectin (Sklice) as an over-the-counter treatment for head lice infestation in patients aged 6 months and older.

Ivermectin was approved as a prescription treatment for head lice in February 2012, according to an FDA press release, and is now approved as an over-the-counter treatment through an “Rx-to-OTC” switch process. The approval was granted to Arbor Pharmaceuticals.

The expanded approval for ivermectin increases access to effective care for head lice, which is estimated to affect between 6 million and 12 million children each year in the United States, according to the Centers for Disease Control and Prevention.

“The Rx-to-OTC switch process aims to promote public health by increasing consumer access to drugs that would otherwise only be available by prescription,” Theresa Michele, MD, acting director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research, said in the press release.

The FDA also noted in the press release that “Sklice, and its active ingredient ivermectin, have not been shown to be safe or effective for the treatment or prevention of COVID-19 and they are not FDA-approved for this use.”

The drug is approved only for treating head lice, and should be used on the scalp and dry hair, according to the labeling. In the wake of the approval, ivermectin will no longer be available as a prescription drug, according to the FDA, and patients currently using prescription versions should contact their health care providers.

An Rx-to-OTC switch is contingent on the manufacturer’s data showing that the drug is safe and effective when used as directed. In addition, “the manufacturer must show that consumers can understand how to use the drug safely and effectively without the supervision of a health care professional,” according to the FDA.

Christopher Pribula, MD, a hospitalist at Sanford Broadway Medical Center in Fargo, N.D., didn’t anticipate becoming his hospital’s resident expert on COVID-19. Having just returned from vacation in March, he agreed to cover for a colleague on what would become the special care unit. “When our hospital medicine group decided that it would be the COVID unit, I just ran with it,” he said. Dr. Pribula spent the next 18 days doing 8- to 14-hour shifts and learning as much as he could as the hospital – and the nation – wrestled with the pandemic.

“Because I was the first hospitalist, along with our infectious disease specialist, Dr. Avish Nagpal, to really engage with the virus, people came to me with their questions,” Dr. Pribula said. Working to establish protocols for the care of COVID-19 patients involved a lot of planning, from nursing protocols to discharge planning.

Dr. Pribula was part of the hospital’s incident command structure, thought about how the system could scale up for a potential surge, and worked with the North Dakota Medical Association to reach out to outlying medical centers on safety and infection control. He even drew on his prior work experience as a medical technologist doing negative-pressure containment in a cell-processing facility to help create the hospital’s negative-pressure unit in an old ICU.

“We did a lot of communication from the start. To a certain extent we were making it up as we went along, but we sat down and huddled as a team every day at 9 and 4,” he explained. “We started out with observation and retrospective research, and learned piece by piece. But that’s how science works.”

Hospitalists across the country have played leading roles in their hospitals’ and health systems’ response to the pandemic, and not just because they are on the front lines providing patient care. Their job as doctors who work full-time in the hospital makes them natural leaders in improving clinical quality and hospital administrative protocols as well as studying the latest information and educating their colleagues. Responding to the pandemic has required lots of planning, careful attention to schedules and assignments and staff stress, and working with other departments in the hospital and groups in the community, including public health authorities.
 

Where is hospital treatment for COVID-19 at today?

As knowledge has grown, Dr. Pribula said, COVID-19 treatment in the hospital has come to incorporate remdesivir, a broad-spectrum antiviral; dexamethasone, a common steroid medication; and convalescent plasma, blood products from people who have recovered from the illness. “We went from no steroids to giving steroids. We went from putting patients on ventilators to avoid acute respiratory distress syndrome (ARDS) initially to now working to avoid intubation at all costs,” he said.

“What we found is that we need to pressure-support these patients. We do proning and CPAP while we let the lungs heal. By the time they arrive at the hospital, more often than not they’re on the backside of the viral load. But now we’re dealing with the body’s inflammatory response.”

Navneet Attri, MD, a hospitalist at Sutter Santa Rosa Regional Hospital in Santa Rosa, Calif., 50 miles north of San Francisco, experienced fears and uncertainties working at a hospital that treated early COVID patients from the Grand Princess cruise ship. Early on, she wrote a post describing her experience for The Hospitalist Leader, the Society of Hospital Medicine’s blog page.

Dr. Attri said she has gone through the gamut of emotions while caring for COVID-19 patients, addressing their fears and trying to support family members who aren’t allowed to enter the hospital to be at their loved one’s side. Sometimes, patient after patient with COVID-19 becomes almost too much. But seeing a lot of them in the intervening 6 months has increased her confidence level.

Understanding of how the disease is spread has continued to evolve, with a recent return to focusing on airborne transmission, she said. Frontline workers need N95 masks and eye shields, even if all of that PPE feels like a burden. Dr. Attri said she hardly notices the PPE anymore. “Putting it on is just a habit.”

She sits on Sonoma County’s COVID-19 surge planning group, which has representatives from the three local hospitals, the public health department, and other community agencies. “I report back to my hospitalist group about the situation in the community. Because our facilities were well prepared, our hospitals have not been overwhelmed,” she said.
 

The importance of teamwork

Sunil Shah, MD, a hospitalist with Northwell Health’s Southside Hospital in Bay Shore, N.Y., is part of the massive hospital medicine team, including reassigned specialists and volunteers from across the country, deployed at Northwell hospitals in Greater New York City and Long Island during the COVID-19 surge. Northwell probably has cared for more COVID-19 patients than any other health system in the country, and at the height of the surge the intensity of hospital care was like nothing he’s ever seen. But he also expressed gratitude that doctors from other parts of the country were willing to come and help out.

Southside Hospital went almost overnight from a 200-bed acute facility to a full, 350-bed, regional COVID-19–only hospital. “On busy days, our entire hospital was like a floating ICU,” he said. “You’d hear ‘rapid response’ or ‘code blue’ over the intercom every few seconds. Normally we’d have a designated rapid response person for the day, but with COVID, everybody stepped in to help – whoever was closest,” he said.

Majid Sheikh, MD, a hospitalist at Emory University Hospital in Atlanta, also became a go-to COVID-19 expert for his group. “I didn’t specifically volunteer, but my partner and I had the first cases, and the leadership group was happy to have us there,” he explained.

“One interesting thing I learned was the concept of the ‘happy’ hypoxemic patient, who is having a significant drop in oxygen saturation without developing any obvious signs of respiratory distress,” he said. “We’d be checking the accuracy of the reading and trying to figure out if it was real.” Emory was also one of the leaders in studying anticoagulant treatments for COVID-19 patients.

“Six months later I would say we’re definitely getting better outcomes on the floor, and our COVID patients aren’t landing in the ICU as easily,” Dr. Sheikh said. “It was scary at first, and doubly scary when doctors sometimes don’t feel they can say, ‘Hey, I’m scared too,’ or ‘By the way, I really don’t know what I’m doing.’ So, we’d be trying to reassure the patients when the information was coming to us in fragments.”

But he also believes that the pandemic has afforded hospitalists the opportunity to be the clinical detectives they were trained to be, sifting through clues. “I had to think more and really pay attention clinically in a much different way. You could say it was exciting and scary at the same time,” he said.
 

A human fix in the hospital

Dr. Pribula agreed that the pandemic has been both a difficult experience and a rewarding one. “I think of the people I first admitted. If they had shown up even a month later, would they still be with us?” He believes that his group and his field are going to get to a place where they have solid treatment plans for how to provide optimal care and how to protect providers from exposure.

One of the first COVID-19 patients in Fargo had dementia and was very distressed. “She had no idea why nobody was visiting or why we wouldn’t let her out of her room,” Dr. Pribula said. “Instead of reaching for sedatives, one of our nurses went into the room and talked with her, prayed a rosary, and played two hands of cards with her and didn’t have to sedate her. That’s what people need when they’re alone and scared. It wasn’t a medical fix but a human fix.”

A new poll of emergency physicians on the front lines of the COVID-19 pandemic shows many are fearful of seeking mental health care for fear of stigma and the potential career impact.

The results of the nationally representative poll, conducted Oct. 7-13 by the American College of Emergency Physicians, showed almost half (45%) of 862 emergency physician respondents reported being uncomfortable seeking available psychiatric care. The poll had a margin of error of plus or minus 3 percentage points.

The findings provide new insight into both the challenges of serving in emergency medicine during the pandemic and the persistent barriers to mental health care in terms of stigma and concerns about potential career setbacks.

In the poll, 42% of respondents said they have been feeling much more stress since the start of COVID-19, with another 45% report they were feeling somewhat more stressed.

When asked about causes of stress related directly to COVID-19, 83% cited concerns about family and friends contracting COVID-19. Also factoring into emergency physicians’ stress and burnout were concerns about their own safety (80%) and lack of personal protective equipment or other needed resources (60%).

In the poll, 29% of respondents reported having excellent access to mental health treatment and 42% reported having good access. Despite this, 30% of respondents still reported feeling there was a lot of stigma in their workplace about seeking mental health treatment, with another 43% reporting they felt there was some stigma.

Poll results also showed that 24% of respondents were very concerned about what might happen with their employment if they were to seek mental health treatment, with another 33% saying they were somewhat concerned.

In recent years there have been efforts to break down cultural roadblocks in medicine that deter many physicians from seeking mental health treatment, but more needs to be done, said Mark Rosenberg, DO, MBA, who was elected president of ACEP at last weekend’s annual meeting, ACEP20.

“The pandemic emphatically underscores our need to change the status quo when it comes to physicians’ mental health,” Dr. Rosenberg said.

As previously reported by Medscape Medical News, current efforts to remove such barriers include initiatives to limit inquiries into clinicians’ past or present mental health treatment.

In May, the influential Joint Commission issued a statement urging organizations to refrain from asking about any history of mental health conditions or treatment. The Joint Commission said it supports recommendations already made by the Federation of State Medical Boards and the American Medical Association to limit inquiries on licensing applications to conditions that currently impair a clinician’s ability to perform their job.

Also supporting these efforts is the Dr. Lorna Breen Heroes’ Foundation, created in honor of an emergency physician who died by suicide in April amid the pandemic.

Lorna Breen, MD, had been working intensely in the response to the pandemic. During one shift, she covered two EDs in Manhattan at locations 5 miles apart, according to a backgrounder on the foundation’s web site.

At an ACEP press conference this week, Dr. Breen’s brother-in-law, J. Corey Feist, JD, MBA, cofounder of the foundation, noted that some states’ licensing applications for physicians include questions that fall outside of the boundaries of the Americans With Disabilities Act. He cited an analysis of state medical boards’ initial licensing questions published in 2018 in the Journal of the American Academy of Psychiatry and the Law.

In many cases, states have posed questions that extend beyond an assessment of a physician’s current ability to care for patients, creating a needless hurdle to seeking care, wrote the paper’s lead author, Carol North, MD, of the University of Texas Southwestern Medical Center, Dallas.

“Over the years, many medical licensure boards have asked applicants intrusive questions about whether they have any psychiatric history. This has created a major problem for applicants, and unfortunately this has discouraged many of those who need psychiatric treatment from seeking it because of fear of the questions,” Dr. North and colleagues noted. They cited Ohio as an example of a state that had overhauled its approach to questioning to bring it in compliance with the ADA.

Ohio previously required applicants to answer lengthy questions about their mental health, including:

• Within the last 10 years, have you been diagnosed with or have you been treated for bipolar disorder, schizophrenia, paranoia, or any other psychotic disorder?
• Have you, since attaining the age of eighteen or within the last 10 years, whichever period is shorter, been admitted to a hospital or other facility for the treatment of bipolar disorder, schizophrenia, paranoia, or any other psychotic disorder?
• Do you have, or have you been diagnosed as having, a medical condition which in any way impairs or limits your ability to practice medicine with reasonable skill and safety?

In the new version, the single question reads: “In the past 5 years, have you been diagnosed as having, or been hospitalized for, a medical condition which in any way impairs or limits your ability to practice medicine with reasonable skill and safety?”

Other states such as New York pose no mental health questions on applications for licensure.

Still, even when states have nondiscriminatory laws, physicians may not be aware of them, said Mr. Feist at an ACEP press conference. In addition to his work with the foundation, Mr. Feist is the CEO of the University of Virginia Physicians Group.

He said his sister-in-law Dr. Breen may have worried without cause about potential consequences of seeking psychiatric treatment during the pandemic. In addition, physicians in need of psychiatric care may worry about encountering hitches with medical organizations and insurers.

“This stigma and this fear of professional action on your license or your credentialing or privileging is pervasive throughout the industry,” he said.

Two experts at IDWeek 2020 debated the best treatment for patients with the most severe type of Clostridioides difficile infection – fulminant C. diff. The discussion pitted fecal microbiota transplants (FMT) from the stool of healthy donors against traditional antibiotics.

Fulminant C. diff infection (CDI) represents about 8% of all CDI cases and is often fatal. Patients frequently don’t respond to maximum antibiotic therapy.

Should these patients be treated with FMT before surgery is considered?

“Unequivocally, yes,” said Jessica R. Allegretti, MD, MPH, associate director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital in Boston.
 

Patients face full colectomy

Fulminant infection, she says, typically requires a total abdominal colectomy with end ileostomy.

“Patients have a quite high perioperative and intraoperative mortality because this is typically an older population with significant comorbidities,” she said.

Often the patients are poor candidates for surgery, she added.

She pointed to the efficacy of FMT in studies such as one published in Gut Microbes in 2017. The study, by Monika Fischer, MD, of Indiana University, Indianapolis, and colleagues showed a 91% cure rate at 1 month in severe patients with an average of 1.5 fecal transplants, noting that was “quite remarkable” in this very sick population.

Though FMT is not approved by the US Food and Drug Administration for fulminant CDI, Dr. Allegretti said, the FDA does allow treatment under “enforcement discretion,” which means no investigational new drug license is needed specifically if treating CDI patients who haven’t responded to standard therapy, as long as proper consent has been obtained.

“This is a patient population that is likely going to die,” she said. “If you were the one in the ICU with fulminant C. diff and you’ve been on maximum therapy for 3-5 days and you’re not getting better, wouldn’t you want somebody to offer you a fecal transplant and give you the chance to recover and leave the hospital with your colon intact? The data suggest that is possible, with a high likelihood and a good safety profile.”

She said the most recent guidelines have supported FMT, and emerging guidelines coming within months “will support this as well.”
 

Unknowns with FMT

Taking the other side of the debate, Kevin Garey, PharmD, chair of the department of pharmacy practice and translational research at University of Houston College of Pharmacy, warned against trading traditional antibiotics, such as vancomycin and fidaxomicin, for the novelty of FMT.

“With the science of the microbiome and the novelty of fecal microbiota transplantation in expanding use, I think people have somewhat forgotten pharmacotherapy,” he said.

He pointed out safety concerns with FMT reported in June 2019, after which the FDA issued an alert. Two immunocompromised patients who received FMT, both from the same donor, developed invasive infections caused by extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli. One died.

The FDA explained that the donated FMT samples the patients received were not tested for ESBL-producing gram-negative organisms before use.

Dr. Allegretti agreed antibiotics play a role in treatment with FMT, but she argued that the safety profile of FMT remains strong and that the safety issues came from isolated incidents at a single center.

Dr. Garey countered that there are just too many unknowns with FMT.

“We will never know what the next superbug that’s going to land in an FMT is until we’ve identified that superbug in somebody – the next Candida auris, the next CRE [carbapenem-resistant Enterobacteriaceae], the next thing that’s going to show up in FMT – until we get rid of the ‘F,’ “ Dr. Garey said.

“[Until] we get microbial therapy that’s generated without the need for healthy donors, I think we’re always going to be in this problem.”

He said although FMT “has an amazing ability to alter a microbiome” it “pales in comparison” to vancomycin’s ability to do so.

Disruption of the microbiome is, without a doubt, a hallmark of C. diff, but we don’t have to run to FMT,” Dr. Garey said. “We can think about prophylaxis strategies, we can think about new drug development that spares the microbiota. The need for FMT might be a consequence of poor pharmacotherapy management, not a part of pharmacotherapy management.”

Moderator Sam Aitken, PharmD, MPH, a clinical pharmacy specialist in infectious disease at MD Anderson Cancer Center in Houston, said in an interview the speakers found some common ground.

“I think there was a general consensus between both Dr. Allegretti and Dr. Garey that both traditional therapeutics and fecal microbiota transplantation have a role to play in these patients, although there is still quite a bit of discussion around where those might be best positioned,” Dr. Aitken said.

He added, “There’s also a general consensus that there is not likely to be one right answer for all patients with multiple recurrent CDI.”

Dr. Allegretti, Dr. Garey, and Dr. Aitken have disclosed no relevant financial relationships.
