Inflammatory back pain likely underrecognized in primary care

Wed, 05/20/2020 - 12:12

Almost half of people presenting for low back pain to the Tufts University primary care clinic in Boston were not asked about inflammatory signs and symptoms, according to a review of 239 charts there by rheumatologists and rheumatology fellows.

In more than two-thirds of cases, the reviewers were unable to determine if patients had inflammatory back pain or not based on what was documented. When symptoms relevant to inflammation – such as improvement with movement – were documented, it wasn’t clear if providers were actually trying to solicit a history of inflammation or if they simply recorded what patients volunteered.

Spondyloarthritis was listed in the differential of just five charts (2%), and only eight (3.3%) documented considering a rheumatology referral.

It raises the possibility that, in at least some cases, an opportunity to diagnose and treat spondyloarthritis early was missed. It’s a known problem in the literature; previous studies report a delay of 2-10 years before ankylosing spondylitis diagnosis.

“In our primary care practice, there appears to be poor awareness of inflammatory back pain [that] could lead to diagnostic delay,” said senior investigator and rheumatologist Steven Vlad, MD, PhD, an assistant professor at Tufts. Primary care providers are usually the first to see back pain patients, but they “did not seem to be screening for” inflammation, he said.

Dr. Vlad presented the study results at the virtual annual meeting of the Spondyloarthritis Research and Treatment Network. The meeting was held online this year because of the COVID-19 pandemic.

The findings suggest that a reminder to check for inflammation might be in order. Dr. Vlad and his colleagues have since held educational sessions, and plan to do more, with the idea of repeating the study in a year or 2 to see if the sessions made a difference.



“People take away what they learn as residents. We probably need to focus on resident education if we really want to make a dent in this,” he said.

The generalizability of the single-center results is unclear, and it’s possible at least in some cases that providers asked the right questions but did not document them in the chart. Even so, the issue “deserves future study in other populations,” Dr. Vlad said.

The subjects all had a diagnostic code for low back pain and were seen by Tuft’s primary care at least twice 3 or more months apart, which indicated chronic pain. Chart reviews included clinical notes, labs, imaging studies, and consultation reports. “We looked for specific documentation that primary care physicians had been asking questions related to inflammatory back pain,” Dr. Vlad explained.

Overall, 128 charts (53.6%) documented some feature of inflammatory low back pain. Insidious onset was the most common, but morning stiffness, a cardinal sign, was the least common, noted in only five charts (2%). About 30% of the subjects had a lumbar spine x-ray, which was the most common imaging study, followed by lumbar spine MRI. Only a handful had imaging of the sacroiliac joints.

In 111 charts (46.4%), there was no documentation that primary care providers had looked for inflammatory features or asked questions about them.

Patients were seen from Jan. 2016 to May 2018. The average age in the study was 37.6 years, and two-thirds of the subjects were women.

Funding source and disclosures weren’t reported.

COVID-19 exacerbating challenges for Latino patients

Disproportionate burden of pandemic complicates mental health care

Pamela Montano, MD, recalls the recent case of a patient with bipolar II disorder who was improving after treatment with medication and therapy when her life was upended by the COVID-19 pandemic.

“The COVID pandemic has highlighted the structural inequities that affect the Latino population [both] immigrant and nonimmigrant,” said Dr. Pamela Montano.

The patient, who is Puerto Rican, lost two cousins to the virus, two of her brothers fell ill, and her sister became sick with coronavirus, said Dr. Montano, director of the Latino Bicultural Clinic at Gouverneur Health in New York. The patient was then left to care for her sister’s toddlers along with the patient’s own children, one of whom has special needs.

“After this happened, it increased her anxiety,” Dr. Montano said in an interview. “She’s not sleeping, and she started having panic attacks. My main concern was how to help her cope.”

Across the country, clinicians who treat mental illness and behavioral disorders in Latino patients are facing similar experiences and challenges associated with COVID-19 and the ensuing pandemic response. Current data suggest a disproportionate burden of illness and death from the novel coronavirus among racial and ethnic groups, particularly black and Hispanic patients. The disparities are likely attributable to economic and social conditions more common among such populations, compared with non-Hispanic whites, in addition to isolation from resources, according to the Centers for Disease Control and Prevention.

A recent New York City Department of Health study based on data that were available in late April found that deaths from COVID-19 were substantially higher for black and Hispanic/Latino patients than for white and Asian patients. The death rate per 100,000 population was 209.4 for blacks, 195.3 for Hispanics/Latinos, 107.7 for whites, and 90.8 for Asians.

“The COVID pandemic has highlighted the structural inequities that affect the Latino population [both] immigrant and nonimmigrant,” said Dr. Montano, a board member of the American Society of Hispanic Psychiatry and the officer of infrastructure and advocacy for the Hispanic Caucus of the American Psychiatric Association. “This includes income inequality, poor nutrition, history of trauma and discrimination, employment issues, quality education, access to technology, and overall access to appropriate cultural linguistic health care.”
 

Navigating challenges

For mental health professionals treating Latino patients, COVID-19 and the pandemic response have generated a range of treatment obstacles.

Dr. Jacqueline Posada

The transition to telehealth for example, has not been easy for some patients, said Jacqueline Posada, MD, consultation-liaison psychiatry fellow at the Inova Fairfax Hospital–George Washington University program in Falls Church, Va., and an APA Substance Abuse and Mental Health Services Administration minority fellow. Some patients lack Internet services, others forget virtual visits, and some do not have working phones, she said.

“I’ve had to be very flexible,” she said in an interview. “Ideally, I’d love to see everybody via video chat, but a lot of people either don’t have a stable Internet connection or Internet, so I meet the patient where they are. Whatever they have available, that’s what I’m going to use. If they don’t answer on the first call, I will call again at least three to five times in the first 15 minutes to make sure I’m giving them an opportunity to pick up the phone.”

In addition, Dr. Posada has encountered disconnected phones when calling patients for appointments. In such cases, Dr. Posada contacts the patient’s primary care physician to relay medication recommendations in case the patient resurfaces at the clinic.

In other instances, patients are not familiar with video technology, or they must travel to a friend or neighbor’s house to access the technology, said Hector Colón-Rivera, MD, an addiction psychiatrist and medical director of the Asociación Puertorriqueños en Marcha Behavioral Health Program, a nonprofit organization based in the Philadelphia area. Telehealth visits frequently include appearances by children, family members, barking dogs, and other distractions, said Dr. Colón-Rivera, president of the APA Hispanic Caucus.

Dr. Hector Colon-Rivera

“We’re seeing things that we didn’t used to see when they came to our office – for good or for bad,” said Dr. Colón-Rivera, an attending telemedicine physician at the University of Pittsburgh Medical Center. “It could be a good chance to meet our patient in a different way. Of course, it creates different stressors. If you have five kids on top of you and you’re the only one at home, it’s hard to do therapy.”

Psychiatrists are also seeing prior health conditions in patients exacerbated by COVID-19 fears and new health problems arising from the current pandemic environment. Dr. Posada recalls a patient whom she successfully treated for premenstrual dysphoric disorder who recently descended into severe clinical depression. The patient, from Colombia, was attending school in the United States on a student visa and supporting herself through child care jobs.

“So much of her depression was based on her social circumstance,” Dr. Posada said. “She had lost her job, her sister had lost her job so they were scraping by on her sister’s husband’s income, and the thing that brought her joy, which was going to school and studying so she could make a different life for herself than what her parents had in Colombia, also seemed like it was out of reach.”

Dr. Colón-Rivera recently received a call from a hospital where one of his patients was admitted after becoming delusional and psychotic. The patient was correctly taking medication prescribed by Dr. Colón-Rivera, but her diabetes had become uncontrolled because she was unable to reach her primary care doctor and couldn’t access the pharmacy. Her blood sugar level became elevated, leading to the delusions.

“A patient that was perfectly stable now is unstable,” he said. “Her diet has not been good enough through the pandemic, exacerbating her diabetes. She was admitted to the hospital for delirium. Patients are suffering from changes in their daily structure affecting not only their mental health, but their health in general.”

 

 

Compounding of traumas

For many Latino patients, the adverse impacts of the pandemic comes on top of multiple prior traumas, such as violence exposures, discrimination, and economic issues, said Lisa Fortuna, MD, MPH, MDiv, chief of psychiatry and vice chair at Zuckerberg San Francisco General Hospital. A 2017 analysis found that nearly four in five Latino youth face at least one traumatic childhood experience, like poverty or abuse, and that about 29% of Latino youth experience four or more of these traumas.

Dr. Lisa Fortuna

Immigrants in particular, may have faced trauma in their home country and/or immigration trauma, Dr. Fortuna added. A 2013 study on immigrant Latino adolescents for example, found that 29% of foreign-born adolescents and 34% of foreign-born parents experienced trauma during the migration process (Int Migr Rev. 2013 Dec;47(4):10).

“All of these things are cumulative,” Dr. Fortuna said. “Then when you’re hit with a pandemic, all of the disparities that you already have and all the stress that you already have are compounded. This is for the kids, too, who have been exposed to a lot of stressors and now maybe have family members that have been ill or have died. All of these things definitely put people at risk for increased depression [and] the worsening of any preexisting posttraumatic stress disorder. We’ve seen this in previous disasters, and I expect that’s what we’re going to see more of with the COVID-19 pandemic.”

At the same time, a central cultural value of many Latinos is family unity, Dr. Montano said, a foundation that is now being strained by social distancing and severed connections.

“This has separated many families,” she said. “There has been a lot of loneliness and grief.”

Mistrust and fear toward the government, public agencies, and even the health system itself act as further hurdles for some Latinos in the face of COVID-19. In areas with large immigrant populations such as San Francisco, Dr. Fortuna noted, it’s not uncommon for undocumented patients to avoid accessing medical care and social services, or visiting emergency departments for needed care for fear of drawing attention to themselves or possible detainment.

“The fact that so many people showed up at our hospital so ill and ended up in the ICU – that could be a combination of factors. Because the population has high rates of diabetes and hypertension, that might have put people at increased risk for severe illness,” she said. “But some people may have been holding out for care because they wanted to avoid being in places out of fear of immigration scrutiny.”
 

Overcoming language barriers

Compounding the challenging pandemic landscape for Latino patients is the fact that many state resources about COVID-19 have not been translated to Spanish, Dr. Colón-Rivera said. He was troubled recently when he went to several state websites and found limited to no information in Spanish about the coronavirus. Some data about COVID-19 from the federal government were not translated to Spanish until officials received pushback, he added. Even now, press releases and other information disseminated by the federal government about the virus appear to be translated by an automated service – and lack sense and context.

The state agencies in Pennsylvania have been alerted to the absence of Spanish information, but change has been slow, he noted.

“In Philadelphia, 23% speaks a language other than English,” he said. “So we missed a lot of critical information that could have helped to avoid spreading the illness and access support.”

Dr. Fortuna said that California has done better with providing COVID-19–related information in Spanish, compared with some other states, but misinformation about the virus and lingering myths have still been a problem among the Latino community. The University of California, San Francisco, recently launched a Latino Task Force resource website for the Latino community that includes information in English, Spanish, and Yucatec Maya about COVID-19, health and wellness tips, and resources for various assistance needs.

The concerning lack of COVID-19 information translated to Spanish led Dr. Montano to start a Facebook page in Spanish about mental health tips and guidance for managing COVID-19–related issues. She and her team of clinicians share information, videos, relaxation exercises, and community resources on the page, among other posts. “There is also general info and recommendations about COVID-19 that I think can be useful for the community,” she said. “The idea is that patients, the general community, and providers can have share information, hope messages, and ask questions in Spanish.”

Feeling ‘helpless’

A central part of caring for Latino patients during the COVID-19 crisis has been referring them to outside agencies and social services, psychiatrists say. But finding the right resources amid a pandemic and ensuring that patients connect with the correct aid has been an uphill battle.

“We sometimes feel like our hands are tied,” Dr. Colón-Rivera said. “Sometimes, we need to call a place to bring food. Some of the state agencies and nonprofits don’t have delivery systems, so the patient has to go pick up for food or medication. Some of our patients don’t want to go outside. Some do not have cars.”

As a clinician, it can be easy to feel helpless when trying to navigate new challenges posed by the pandemic in addition to other longstanding barriers, Dr. Posada said.

“Already, mental health disorders are so influenced by social situations like poverty, job insecurity, or family issues, and now it just seems those obstacles are even more insurmountable,” she said. “At the end of the day, I can feel like: ‘Did I make a difference?’ That’s a big struggle.”

Dr. Montano’s team, which includes psychiatrists, psychologists, and social workers, have come to rely on virtual debriefings to vent, express frustrations, and support one another, she said. She also recently joined a virtual mind-body skills group as a participant.

“I recognize the importance of getting additional support and ways to alleviate burnout,” she said. “We need to take care of ourselves or we won’t be able to help others.”

Focusing on resilience during the current crisis can be beneficial for both patients and providers in coping and drawing strength, Dr. Posada said.

“When it comes to fostering resilience during times of hardship, I think it’s most helpful to reflect on what skills or attributes have helped during past crises and apply those now – whether it’s turning to comfort from close relationships, looking to religion and spirituality, practicing self-care like rest or exercise, or really tapping into one’s purpose and reason for practicing psychiatry and being a physician,” she said. “The same advice goes for clinicians: We’ve all been through hard times in the past, it’s part of the human condition and we’ve also witnessed a lot of suffering in our patients, so now is the time to practice those skills that have gotten us through hard times in the past.”
 

 

 

Learning lessons from COVID-19

Despite the challenges with moving to telehealth, Dr. Fortuna said the tool has proved beneficial overall for mental health care. For Dr. Fortuna’s team for example, telehealth by phone has decreased the no-show rate, compared with clinic visits, and improved care access.

“We need to figure out how to maintain that,” she said. “If we can build ways for equity and access to Internet, especially equipment, I think that’s going to help.”


In addition, more data are needed about the ways in which COVID-19 is affecting Latino patients, Dr. Colón-Rivera said. Mortality statistics have been published, but information is needed about the rates of infection and manifestation of illness.

Most importantly, the COVID-19 crisis has emphasized the critical need to address and improve the underlying inequity issues among Latino patients, psychiatrists say.

“We really need to think about how there can be partnerships, in terms of community-based Latino business and leaders, multisector resources, trying to think about how we can improve conditions both work and safety for Latinos,” Dr. Fortuna said. “How can schools get support in integrating mental health and support for families, especially now after COVID-19? And really looking at some of these underlying inequities that are the underpinnings of why people were at risk for the disproportionate effects of the COVID-19 pandemic.”

Because the population has high rates of diabetes and hypertension, that might have put people at increased risk for severe illness,” she said. “But some people may have been holding out for care because they wanted to avoid being in places out of fear of immigration scrutiny.”
 

Overcoming language barriers

Compounding the challenging pandemic landscape for Latino patients is the fact that many state resources about COVID-19 have not been translated to Spanish, Dr. Colón-Rivera said. He was troubled recently when he went to several state websites and found limited to no information in Spanish about the coronavirus. Some data about COVID-19 from the federal government were not translated to Spanish until officials received pushback, he added. Even now, press releases and other information disseminated by the federal government about the virus appear to be translated by an automated service – and lack sense and context.

The state agencies in Pennsylvania have been alerted to the absence of Spanish information, but change has been slow, he noted.

“In Philadelphia, 23% speaks a language other than English,” he said. “So we missed a lot of critical information that could have helped to avoid spreading the illness and access support.”

Dr. Fortuna said that California has done better with providing COVID-19–related information in Spanish, compared with some other states, but misinformation about the virus and lingering myths have still been a problem among the Latino community. The University of California, San Francisco, recently launched a Latino Task Force resource website for the Latino community that includes information in English, Spanish, and Yucatec Maya about COVID-19, health and wellness tips, and resources for various assistance needs.

The concerning lack of COVID-19 information translated to Spanish led Dr. Montano to start a Facebook page in Spanish about mental health tips and guidance for managing COVID-19–related issues. She and her team of clinicians share information, videos, relaxation exercises, and community resources on the page, among other posts. “There is also general info and recommendations about COVID-19 that I think can be useful for the community,” she said. “The idea is that patients, the general community, and providers can have share information, hope messages, and ask questions in Spanish.”

Feeling ‘helpless’

A central part of caring for Latino patients during the COVID-19 crisis has been referring them to outside agencies and social services, psychiatrists say. But finding the right resources amid a pandemic and ensuring that patients connect with the correct aid has been an uphill battle.

“We sometimes feel like our hands are tied,” Dr. Colón-Rivera said. “Sometimes, we need to call a place to bring food. Some of the state agencies and nonprofits don’t have delivery systems, so the patient has to go pick up for food or medication. Some of our patients don’t want to go outside. Some do not have cars.”

As a clinician, it can be easy to feel helpless when trying to navigate new challenges posed by the pandemic in addition to other longstanding barriers, Dr. Posada said.

“Already, mental health disorders are so influenced by social situations like poverty, job insecurity, or family issues, and now it just seems those obstacles are even more insurmountable,” she said. “At the end of the day, I can feel like: ‘Did I make a difference?’ That’s a big struggle.”

Dr. Montano’s team, which includes psychiatrists, psychologists, and social workers, have come to rely on virtual debriefings to vent, express frustrations, and support one another, she said. She also recently joined a virtual mind-body skills group as a participant.

“I recognize the importance of getting additional support and ways to alleviate burnout,” she said. “We need to take care of ourselves or we won’t be able to help others.”

Focusing on resilience during the current crisis can be beneficial for both patients and providers in coping and drawing strength, Dr. Posada said.

“When it comes to fostering resilience during times of hardship, I think it’s most helpful to reflect on what skills or attributes have helped during past crises and apply those now – whether it’s turning to comfort from close relationships, looking to religion and spirituality, practicing self-care like rest or exercise, or really tapping into one’s purpose and reason for practicing psychiatry and being a physician,” she said. “The same advice goes for clinicians: We’ve all been through hard times in the past, it’s part of the human condition and we’ve also witnessed a lot of suffering in our patients, so now is the time to practice those skills that have gotten us through hard times in the past.”
 

 

 

Learning lessons from COVID-19

Despite the challenges with moving to telehealth, Dr. Fortuna said the tool has proved beneficial overall for mental health care. For Dr. Fortuna’s team for example, telehealth by phone has decreased the no-show rate, compared with clinic visits, and improved care access.

“We need to figure out how to maintain that,” she said. “If we can build ways for equity and access to Internet, especially equipment, I think that’s going to help.”


In addition, more data are needed about the ways in which COVID-19 is affecting Latino patients, Dr. Colón-Rivera said. Mortality statistics have been published, but information is needed about the rates of infection and manifestation of illness.

Most importantly, the COVID-19 crisis has emphasized the critical need to address and improve the underlying inequity issues among Latino patients, psychiatrists say.

“We really need to think about how there can be partnerships, in terms of community-based Latino business and leaders, multisector resources, trying to think about how we can improve conditions both work and safety for Latinos,” Dr. Fortuna said. “How can schools get support in integrating mental health and support for families, especially now after COVID-19? And really looking at some of these underlying inequities that are the underpinnings of why people were at risk for the disproportionate effects of the COVID-19 pandemic.”

Pamela Montano, MD, recalls the recent case of a patient with bipolar II disorder who was improving after treatment with medication and therapy when her life was upended by the COVID-19 pandemic.

“The COVID pandemic has highlighted the structural inequities that affect the Latino population [both] immigrant and nonimmigrant,” said Dr. Pamela Montano.

The patient, who is Puerto Rican, lost two cousins to the virus, two of her brothers fell ill, and her sister became sick with coronavirus, said Dr. Montano, director of the Latino Bicultural Clinic at Gouverneur Health in New York. The patient was then left to care for her sister’s toddlers along with the patient’s own children, one of whom has special needs.

“After this happened, it increased her anxiety,” Dr. Montano said in an interview. “She’s not sleeping, and she started having panic attacks. My main concern was how to help her cope.”

Across the country, clinicians who treat mental illness and behavioral disorders in Latino patients are facing similar experiences and challenges associated with COVID-19 and the ensuing pandemic response. Current data suggest a disproportionate burden of illness and death from the novel coronavirus among racial and ethnic groups, particularly black and Hispanic patients. The disparities are likely attributable to economic and social conditions more common among such populations, compared with non-Hispanic whites, in addition to isolation from resources, according to the Centers for Disease Control and Prevention.

A recent New York City Department of Health study based on data that were available in late April found that deaths from COVID-19 were substantially higher for black and Hispanic/Latino patients than for white and Asian patients. The death rate per 100,000 population was 209.4 for blacks, 195.3 for Hispanics/Latinos, 107.7 for whites, and 90.8 for Asians.

“The COVID pandemic has highlighted the structural inequities that affect the Latino population [both] immigrant and nonimmigrant,” said Dr. Montano, a board member of the American Society of Hispanic Psychiatry and the officer of infrastructure and advocacy for the Hispanic Caucus of the American Psychiatric Association. “This includes income inequality, poor nutrition, history of trauma and discrimination, employment issues, quality education, access to technology, and overall access to appropriate cultural linguistic health care.”
 

Navigating challenges

For mental health professionals treating Latino patients, COVID-19 and the pandemic response have generated a range of treatment obstacles.

Dr. Jacqueline Posada

The transition to telehealth for example, has not been easy for some patients, said Jacqueline Posada, MD, consultation-liaison psychiatry fellow at the Inova Fairfax Hospital–George Washington University program in Falls Church, Va., and an APA Substance Abuse and Mental Health Services Administration minority fellow. Some patients lack Internet services, others forget virtual visits, and some do not have working phones, she said.

“I’ve had to be very flexible,” she said in an interview. “Ideally, I’d love to see everybody via video chat, but a lot of people either don’t have a stable Internet connection or Internet, so I meet the patient where they are. Whatever they have available, that’s what I’m going to use. If they don’t answer on the first call, I will call again at least three to five times in the first 15 minutes to make sure I’m giving them an opportunity to pick up the phone.”

In addition, Dr. Posada has encountered disconnected phones when calling patients for appointments. In such cases, Dr. Posada contacts the patient’s primary care physician to relay medication recommendations in case the patient resurfaces at the clinic.

In other instances, patients are not familiar with video technology, or they must travel to a friend or neighbor’s house to access the technology, said Hector Colón-Rivera, MD, an addiction psychiatrist and medical director of the Asociación Puertorriqueños en Marcha Behavioral Health Program, a nonprofit organization based in the Philadelphia area. Telehealth visits frequently include appearances by children, family members, barking dogs, and other distractions, said Dr. Colón-Rivera, president of the APA Hispanic Caucus.

Dr. Hector Colon-Rivera

“We’re seeing things that we didn’t used to see when they came to our office – for good or for bad,” said Dr. Colón-Rivera, an attending telemedicine physician at the University of Pittsburgh Medical Center. “It could be a good chance to meet our patient in a different way. Of course, it creates different stressors. If you have five kids on top of you and you’re the only one at home, it’s hard to do therapy.”

Psychiatrists are also seeing prior health conditions in patients exacerbated by COVID-19 fears and new health problems arising from the current pandemic environment. Dr. Posada recalls a patient whom she successfully treated for premenstrual dysphoric disorder who recently descended into severe clinical depression. The patient, from Colombia, was attending school in the United States on a student visa and supporting herself through child care jobs.

“So much of her depression was based on her social circumstance,” Dr. Posada said. “She had lost her job, her sister had lost her job so they were scraping by on her sister’s husband’s income, and the thing that brought her joy, which was going to school and studying so she could make a different life for herself than what her parents had in Colombia, also seemed like it was out of reach.”

Dr. Colón-Rivera recently received a call from a hospital where one of his patients was admitted after becoming delusional and psychotic. The patient was correctly taking medication prescribed by Dr. Colón-Rivera, but her diabetes had become uncontrolled because she was unable to reach her primary care doctor and couldn’t access the pharmacy. Her blood sugar level became elevated, leading to the delusions.

“A patient that was perfectly stable now is unstable,” he said. “Her diet has not been good enough through the pandemic, exacerbating her diabetes. She was admitted to the hospital for delirium. Patients are suffering from changes in their daily structure affecting not only their mental health, but their health in general.”

 

 

Compounding of traumas

For many Latino patients, the adverse impacts of the pandemic comes on top of multiple prior traumas, such as violence exposures, discrimination, and economic issues, said Lisa Fortuna, MD, MPH, MDiv, chief of psychiatry and vice chair at Zuckerberg San Francisco General Hospital. A 2017 analysis found that nearly four in five Latino youth face at least one traumatic childhood experience, like poverty or abuse, and that about 29% of Latino youth experience four or more of these traumas.

Dr. Lisa Fortuna

Immigrants in particular, may have faced trauma in their home country and/or immigration trauma, Dr. Fortuna added. A 2013 study on immigrant Latino adolescents for example, found that 29% of foreign-born adolescents and 34% of foreign-born parents experienced trauma during the migration process (Int Migr Rev. 2013 Dec;47(4):10).

“All of these things are cumulative,” Dr. Fortuna said. “Then when you’re hit with a pandemic, all of the disparities that you already have and all the stress that you already have are compounded. This is for the kids, too, who have been exposed to a lot of stressors and now maybe have family members that have been ill or have died. All of these things definitely put people at risk for increased depression [and] the worsening of any preexisting posttraumatic stress disorder. We’ve seen this in previous disasters, and I expect that’s what we’re going to see more of with the COVID-19 pandemic.”

At the same time, a central cultural value of many Latinos is family unity, Dr. Montano said, a foundation that is now being strained by social distancing and severed connections.

“This has separated many families,” she said. “There has been a lot of loneliness and grief.”

Mistrust and fear toward the government, public agencies, and even the health system itself act as further hurdles for some Latinos in the face of COVID-19. In areas with large immigrant populations such as San Francisco, Dr. Fortuna noted, it’s not uncommon for undocumented patients to avoid accessing medical care and social services, or visiting emergency departments for needed care for fear of drawing attention to themselves or possible detainment.

“The fact that so many people showed up at our hospital so ill and ended up in the ICU – that could be a combination of factors. Because the population has high rates of diabetes and hypertension, that might have put people at increased risk for severe illness,” she said. “But some people may have been holding out for care because they wanted to avoid being in places out of fear of immigration scrutiny.”

Compounding the challenging pandemic landscape for Latino patients is the fact that many state resources about COVID-19 have not been translated to Spanish, Dr. Colón-Rivera said. He was troubled recently when he went to several state websites and found limited to no information in Spanish about the coronavirus. Some data about COVID-19 from the federal government were not translated to Spanish until officials received pushback, he added. Even now, press releases and other information disseminated by the federal government about the virus appear to be translated by an automated service – and lack sense and context.

The state agencies in Pennsylvania have been alerted to the absence of Spanish information, but change has been slow, he noted.

“In Philadelphia, 23% speaks a language other than English,” he said. “So we missed a lot of critical information that could have helped to avoid spreading the illness and access support.”

Dr. Fortuna said that California has done better with providing COVID-19–related information in Spanish, compared with some other states, but misinformation about the virus and lingering myths have still been a problem among the Latino community.

Biomarkers for inflammation and thrombosis may predict deaths from COVID-19 among critically ill patients, researchers say.

Their prospective cohort study of 1150 patients hospitalized with the disease in New York City also revealed a high proportion of racial and ethnic minorities, and confirmed high rates of critical illness and mortality.

“Of particular interest is the finding that over three quarters of critically ill patients required a ventilator and almost one third required renal dialysis support,” Max O’Donnell, MD, MPH, assistant professor of medicine and epidemiology at Columbia University in New York City, said in a press release.

O’Donnell and colleagues published the results of their study online today in The Lancet. It is the largest prospective cohort study published in the United States, they said.

“Although the clinical spectrum of disease has been characterised in reports from China and Italy, until now, detailed understanding of how the virus is affecting critically ill patients in the US has been limited to reports from a small number of cases,” said Natalie Yip, MD, assistant professor of medicine at Columbia University.

In the cohort, drawn from two NewYork-Presbyterian hospitals, the researchers focused on the 257 (22%) patients who required intensive care. When they estimated inflammation through interleukin-6 (IL-6) concentrations and thrombosis through D-dimer concentrations, they found a 10% increased risk for death with every 10% increase of IL-6 (adjusted hazard ratio [aHR], 1.11; 95% confidence interval [CI], 1.02–1.20) or D-dimer concentration (aHR, 1.10; 95% CI, 1.01–1.19).

“The association of mortality with higher concentrations of IL-6 and d-dimer is particularly relevant for two reasons,” write Giacomo Grasselli, from the Fondazione IRCCS Ca’ Granda Ospediale Maggiore Policlinico, and Alberto Zanella, from the University of Milan, Italy, in an accompanying commentary.

“First, it confirms the key pathogenic role played by the activation of systemic inflammation and endothelial-vascular damage in the development of organ dysfunction,” they write. “Second, it provides the rationale for the design of clinical trials for measuring the efficacy of treatment with immunomodulating and anticoagulant drugs.”

Seventeen percent of patients received interleukin receptor antagonists and 26% received corticosteroids, but the authors did not report any data on the effects of these treatments, or any data about anticoagulant therapies administered.
 

Severe disease common

The study also highlighted a high proportion of ethnic and racial minorities. Sixty-two percent of the critically ill patients were Hispanic or Latinx, 19% Black, 32% White, and 3% Asian.

Their median age was 62 years and 67% were men. Eighty-two percent had at least one chronic illness, most commonly hypertension (63%), followed by diabetes (36%). Forty-six percent were obese.

As of April 28, 2020, 101 (39%) of the critically ill patients had died following a median of 9 days (interquartile range (IQR), 5–15) in the hospital and 94 (37%) remained hospitalized. Of the 203 patients who received invasive mechanical ventilation, 84 (41%) had died.

The poor prognosis of patients requiring ventilation is consistent with data from a report on patients treated in National Health Service intensive care units in England, Wales, and Northern Ireland through May 15. Overall, 11,292 patients with COVID-19 required critical care, and 4855 needed advanced respiratory support. Approximately half of the patients receiving mechanical ventilation had died 30 days after starting critical care.

In the New York study, patients spent an average of 18 days on a ventilator (IQR, 9–28 days). This is a longer period than reported in smaller studies of cases from Washington state, but corresponds with a recent report from Italy, the researchers said.

Remarkably, O’Donnell and colleagues report that almost a third (31%) of critically ill patients developed severe kidney damage and required dialysis.

Mortality was associated with several baseline factors, including older age (aHR, 1.31 [95% CI, 1.09–1.57] per 10-year increase), chronic cardiac disease (aHR, 1.76; 95% CI, 1.08–2·86), and chronic pulmonary disease (aHR, 2.94; 95% CI, 1.48–5.84).

Authors of the New York study reported financial relationships to ICE Neurosystems, ALung Technologies, Baxter, BREETHE, Xenios, Hemovent, Gilead Sciences, Amazon, and Karyopharm Therapeutics. Grasselli reports personal fees from Biotest, Draeger, Fisher & Paykel, Maquet, Merck Sharp & Dohme, and Pfizer, all outside the area of work commented on here. Zanella has disclosed no relevant financial relationships.

A comprehensive review

 

On April 3, the Centers for Disease Control and Prevention issued an advisory that the general public wear cloth face masks when outside, particularly those residing in areas with significant severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) community transmission.1 Recent research reveals several factors related to the nature of the virus as well as the epidemiologic spread of the illness that may have led to this decision.

However, controversy still prevails whether this recommendation will alleviate or aggravate disease progression. With many hospitals across America lacking sufficient personal protective equipment (PPE) and scrambling for supplies, universal masking may create more chaos, especially with certain states imposing monetary fines on individuals spotted outdoors without a mask. With new information being discovered each day about COVID-19, it is more imperative than ever to update existing strategies and formulate more effective methods to flatten the curve.
 

Airborne vs. droplet transmission

According to a scientific brief released by the World Health Organization, there have been studies with mixed evidence and opinions regarding the presence of COVID-19 ribonucleic acid (RNA) in air samples.2 In medRxiv, Santarpia et al., from the University of Nebraska Medical Center, Omaha, detected viral RNA in samples taken from beneath a patient’s bed and from a window ledge, both areas in which neither the patient nor health care personnel had any direct contact. They also found that 66.7% of air samples taken from a hospital hallway carried virus-containing particles.3 It is worth noting that certain aerosol-generating procedures (AGP) may increase the likelihood of airborne dissemination. Whether airborne transmission is a major mode of COVID-19 spread in the community and routine clinical settings (with no aerosol-generating procedures) is still a debatable question without a definitive answer.

Dr. Kavya Bharathidasan

We should consider the epidemiology of COVID-19 thus far in the pandemic to determine if transmission patterns are more consistent with that of other common respiratory viral pathogens or more consistent with that of the agents we classically consider to be transmitted by the airborne route (measles, varicella zoster virus, and Mycobacterium tuberculosis). The attack rates in various settings (household, health care, and the public) as well as the expected number of secondary cases from a single infected individual in a susceptible population (R0) are more consistent with those of a droplet spread pathogen.

For measles, the R0 is 12-18, and the secondary household attack rates are ≥ 90%. In case of the varicella zoster virus, the R0 is ~10, and the secondary household attack rate is 85%. The R0 for pulmonary tuberculosis is up to 10 (per year) and the secondary household attack rate has been reported to be >50%. With COVID-19, the R0 appears to be around 2.5-3 and secondary household attack rates are ~ 10% from data available so far, similar to that of influenza viruses. This discrepancy suggests that droplet transmission may be more likely. The dichotomy of airborne versus droplet mode of spread may be better described as a continuum, as pointed out in a recent article in the JAMA. Infectious droplets form turbulent gas clouds allowing the virus particles to travel further and remain in the air longer.4 The necessary precautions for an airborne illness should be chosen over droplet precautions, especially when there is concern for an AGP.
 

 

 

Universal masking: Risks and benefits

The idea of universal masking has been debated extensively since the initial stages of the COVID-19 pandemic. According to public health authorities, significant exposure is defined as “face-to-face contact within 6 feet with a patient with symptomatic COVID-19” in the range of a few minutes up to 30 minutes.5 The researchers wrote in the New England Journal of Medicine that the chance of catching COVID-19 from a passing interaction in a public space is therefore minimal, and it may seem unnecessary to wear a mask at all times in public.

As reported in Science, randomized clinical studies performed on other viruses in the past have shown no added protection conferred by wearing a mask, though small sample sizes and noncompliance are limiting factors to their validity.6 On the contrary, mask wearing has been enforced in many parts of Asia, including Hong Kong and Singapore with promising results.5 Leung et al. stated in The Lancet that the lack of proof that masks are effective should not rule them as ineffective. Also, universal masking would reduce the stigma around symptomatic individuals covering their faces. It has become a cultural phenomenon in many southeast Asian countries and has been cited as one of the reasons for relatively successful containment in Singapore, South Korea, and Taiwan. The most important benefit of universal masking is protection attained by preventing spread from asymptomatic, mildly symptomatic, and presymptomatic carriers.7

In a study in the New England Journal of Medicine that estimated viral loads during various stages of COVID-19, researchers found that asymptomatic patients had similar viral loads to symptomatic patients, thereby suggesting high potential for transmission.8 Furthermore, numerous cases are being reported concerning the spread of illness from asymptomatic carriers.9-12 In an outbreak at a skilled nursing facility in Washington outlined in MMWR, 13 of 23 residents with positive test results were asymptomatic at the time of testing, and of those, 3 never developed any symptoms.12

Many hospitals are now embracing the policy of universal masking. A mask is a critical component of the personal protective equipment (PPE) clinicians need when caring for symptomatic patients with respiratory viral infections, in conjunction with a gown, gloves, and eye protection. Masking in this context is already part of routine operations in most hospitals. There are two scenarios in which there may be possible benefits. One scenario is the lower likelihood of transmission from asymptomatic and minimally symptomatic health care workers with COVID-19 to other providers and patients. The other less plausible benefit of universal masking among health care workers is that it may provide some protection in the possibility of caring for an unrecognized COVID-19 patient. However, universal masking should be coupled with other favorable practices like temperature checks and symptom screening on a daily basis to avail the maximum benefit from masking. Despite varied opinions on the outcomes of universal masking, this measure helps improve health care workers’ safety, psychological well-being, trust in their hospital, and decreases anxiety of acquiring the illness.
 

 

 

Efficacy of various types of masks

With the possibility of airborne transmission of the virus, are cloth masks as recommended by the CDC truly helpful in preventing infection? A study in the Journal of Medical Virology demonstrates 99.98%, 97.14%, and 95.15% efficacy for N95, surgical, and homemade masks, respectively, in blocking the avian influenza virus (comparable to coronavirus in size and physical characteristics). The homemade mask was created using one layer of polyester cloth and a four-layered kitchen filter paper.13

N95 masks (equivalent to FFP/P2 in European countries) are made of electrostatically charged polypropylene microfibers designed to filter particles measuring 100-300nm in diameter with 95% efficacy. A single SARS-CoV-2 molecule measures 125 nm approximately. N99 (FFP3) and N100 (P3) masks are also available, though not as widely used, with 99% and 99.7% efficacy respectively for the same size range. Though cloth masks are the clear-cut last resort for medical professionals, a few studies state no clinically proven difference in protection between surgical masks and N95 respirators.14,15 Even aerosolized droplets (< 5 mcm) were found to be blocked by surgical masks in a Nature Medicine study in which 4/10 subjects tested positive for coronavirus in exhaled breath samples without masks and 0/10 subjects with masks.16

On the contrary, an Annals of Internal Medicine study of four COVID-19 positive subjects that “neither surgical masks nor cloth masks effectively filtered SARS-CoV-2 during coughs of infected patients.” In fact, more contamination was found on the outer surface of the masks when compared to the inner surface, probably owing to the masks’ aerodynamic properties.17 Because of limitations present in the above-mentioned studies, further research is necessary to conclusively determine which types of masks are efficacious in preventing infection by the virus. In a scarcity of surgical masks and respirators for health care personnel, suboptimal masks can be of some use provided there is adherent use, minimal donning and doffing, and it is to be accompanied by adequate hand washing practices.14

In case of severe infections with high viral loads or patients undergoing aerosol-generating procedures, powered air-purifying respirators (PAPRs) also are advisable as they confer greater protection than N95 respirators, according to a study in the Annals of Work Exposures and Health. Despite being more comfortable for long-term use and accommodative of facial hair, their use is limited because of high cost and difficult maintenance.18 3-D printing also is being used to combat the current shortage of masks worldwide. However, a study from the International Journal of Oral & Maxillofacial Surgery reported that virologic testing for leakage between the two reusable components and contamination of the components themselves after one or multiple disinfection cycles is essential before application in real-life situations.19

Ongoing issues

WHO estimates a monthly requirement of nearly 90 million masks exclusively for health care workers to protect themselves against COVID-19.20 In spite of increasing the production rate by 40%, if the general public hoards masks and respirators, the results could be disastrous. Personal protective equipment is currently at 100 times the usual demand and 20 times the usual cost, with stocks backlogged by 4-6 months. The appropriate order of priority in distribution to health care professionals first, followed by those caring for infected patients is critical.20 In a survey conducted by the Association for Professionals in Infection Control and Epidemiology, results revealed that 48% of the U.S. health care facilities that responded were either out or nearly out of respirators as of March 25. 21

The gravest risk behind the universal masking policy is the likely depletion of medical resources.22 A possible solution to this issue could be to modify the policy to stagger the requirement based on the severity of community transmission in that area of residence. In the article appropriately titled “Rational use of face masks in the COVID-19 pandemic” published in The Lancet Respiratory Medicine, researchers described how the Chinese population was classified into moderate, low, and very-low risk of infection categories and advised to wear a surgical or disposable mask, disposable mask, and no mask respectively.23 This curbs widespread panic and eagerness by the general public to stock up on essential medical equipment when it may not even be necessary.
 

Reuse, extended use, and sterilization

Several studies have been conducted to identify the viability of the COVID-19 on various surfaces.24-25 The CDC and National Institute for Occupational Safety and Health (NIOSH) guidelines state that an N95 respirator can be used up to 8 hours with intermittent or continuous use, though this number is not fixed and heavily depends upon the extent of exposure, risk of contamination, and frequency of donning and doffing26,27. Though traditionally meant for single-time usage, after 8 hours, the mask can be decontaminated and reused. The CDC defines extended use as the “practice of wearing the same N95 respirator for repeated close-contact encounters with several patients, without removing the respirator between patient encounters.” Reuse is defined as “using the same N95 respirator for multiple encounters with patients but removing it (‘doffing’) after each encounter. The respirator is stored in between encounters to be put on again (‘donned’) prior to the next encounter with a patient.”

It has been established that extended use is more advisable than reuse given the lower risk of self-inoculation. Furthermore, health care professionals are urged to wear a cleanable face shield or disposable mask over the respirator to minimize contamination and practice diligent hand hygiene before and after handling the respirator. N95 respirators are to be discarded following aerosol-generating procedures or if they come in contact with blood, respiratory secretions, or bodily fluids. They should also be discarded in case of close contact with an infected patient or if they cause breathing difficulties to the wearer.27 This may not always be possible given the unprecedented shortage of PPE, hence decontamination techniques and repurposing are the need of the hour.

In Anesthesia & Analgesia, Naveen Nathan, MD, of Northwestern University, Chicago, recommends recycling four masks in a series, using one per day, keeping the mask in a dry, clean environment, and then repeating use of the first mask on the 5th day, the second on the 6th day, and so forth. This ensures clearance of the virus particles by the next use. Alternatively, respirators can be sterilized between uses by heating to 70º C (158º F) for 30 minutes. Liquid disinfectants such as alcohol and bleach as well as ultraviolet rays in sunlight tend to damage masks.28 Steam sterilization is the most commonly utilized technique in hospitals. Other methods, described by the N95/PPE Working Group, report include gamma irradiation at 20kGy (2MRad) for large-scale sterilization (though the facilities may not be widely available), vaporized hydrogen peroxide, ozone decontamination, ultraviolet germicidal irradiation, and ethylene oxide.29 Though a discussion on various considerations of decontamination techniques is out of the scope of this article, detailed guidelines have been published by the CDC30 and the COVID-19 Healthcare Coalition.30

 

 

Conclusion

A recent startling discovery reported on in Emerging Infectious Diseases suggests that the basic COVID-19 reproductive number (R0) is actually much higher than previously thought. Using expanded data, updated epidemiologic parameters, and the current outbreak dynamics in Wuhan, the team came to the conclusion that the R0 for the novel coronavirus is actually 5.7 (95% CI 3.8-8.9), compared with an initial estimate of 2.2-2.7.31 Concern for transmissibility demands heightened prevention strategies until more data evolves. The latest recommendation by the CDC regarding cloth masking in the public may help slow the progression of the pandemic. However, it is of paramount importance to keep in mind that masks alone are not enough to control the disease and must be coupled with other nonpharmacologic interventions such as social distancing, quarantining/isolation, and diligent hand hygiene.

This ensures clearance of the virus particles by the next use. Alternatively, respirators can be sterilized between uses by heating to 70º C (158º F) for 30 minutes. Liquid disinfectants such as alcohol and bleach as well as ultraviolet rays in sunlight tend to damage masks.28 Steam sterilization is the most commonly utilized technique in hospitals. Other methods, described by the N95/PPE Working Group, report include gamma irradiation at 20kGy (2MRad) for large-scale sterilization (though the facilities may not be widely available), vaporized hydrogen peroxide, ozone decontamination, ultraviolet germicidal irradiation, and ethylene oxide.29 Though a discussion on various considerations of decontamination techniques is out of the scope of this article, detailed guidelines have been published by the CDC30 and the COVID-19 Healthcare Coalition.30

 

 

Conclusion

A recent startling discovery reported on in Emerging Infectious Diseases suggests that the basic COVID-19 reproductive number (R0) is actually much higher than previously thought. Using expanded data, updated epidemiologic parameters, and the current outbreak dynamics in Wuhan, the team came to the conclusion that the R0 for the novel coronavirus is actually 5.7 (95% CI 3.8-8.9), compared with an initial estimate of 2.2-2.7.31 Concern for transmissibility demands heightened prevention strategies until more data evolves. The latest recommendation by the CDC regarding cloth masking in the public may help slow the progression of the pandemic. However, it is of paramount importance to keep in mind that masks alone are not enough to control the disease and must be coupled with other nonpharmacologic interventions such as social distancing, quarantining/isolation, and diligent hand hygiene.

On April 3, the Centers for Disease Control and Prevention issued an advisory that the general public wear cloth face masks when outside, particularly those residing in areas with significant severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) community transmission.1 Recent research reveals several factors related to the nature of the virus as well as the epidemiologic spread of the illness that may have led to this decision.

Dr. Raghavendra Tirupathi

However, controversy still prevails whether this recommendation will alleviate or aggravate disease progression. With many hospitals across America lacking sufficient personal protective equipment (PPE) and scrambling for supplies, universal masking may create more chaos, especially with certain states imposing monetary fines on individuals spotted outdoors without a mask. With new information being discovered each day about COVID-19, it is more imperative than ever to update existing strategies and formulate more effective methods to flatten the curve.
 

Airborne vs. droplet transmission

According to a scientific brief released by the World Health Organization, there have been studies with mixed evidence and opinions regarding the presence of COVID-19 ribonucleic acid (RNA) in air samples.2 In medRxiv, Santarpia et al., from the University of Nebraska Medical Center, Omaha, detected viral RNA in samples taken from beneath a patient’s bed and from a window ledge, both areas in which neither the patient nor health care personnel had any direct contact. They also found that 66.7% of air samples taken from a hospital hallway carried virus-containing particles.3 It is worth noting that certain aerosol-generating procedures (AGP) may increase the likelihood of airborne dissemination. Whether airborne transmission is a major mode of COVID-19 spread in the community and routine clinical settings (with no aerosol-generating procedures) is still a debatable question without a definitive answer.

Dr. Kavya Bharathidasan

We should consider the epidemiology of COVID-19 thus far in the pandemic to determine if transmission patterns are more consistent with that of other common respiratory viral pathogens or more consistent with that of the agents we classically consider to be transmitted by the airborne route (measles, varicella zoster virus, and Mycobacterium tuberculosis). The attack rates in various settings (household, health care, and the public) as well as the expected number of secondary cases from a single infected individual in a susceptible population (R0) are more consistent with those of a droplet spread pathogen.

For measles, the R0 is 12-18, and the secondary household attack rates are ≥ 90%. In case of the varicella zoster virus, the R0 is ~10, and the secondary household attack rate is 85%. The R0 for pulmonary tuberculosis is up to 10 (per year) and the secondary household attack rate has been reported to be >50%. With COVID-19, the R0 appears to be around 2.5-3 and secondary household attack rates are ~ 10% from data available so far, similar to that of influenza viruses. This discrepancy suggests that droplet transmission may be more likely. The dichotomy of airborne versus droplet mode of spread may be better described as a continuum, as pointed out in a recent article in the JAMA. Infectious droplets form turbulent gas clouds allowing the virus particles to travel further and remain in the air longer.4 The necessary precautions for an airborne illness should be chosen over droplet precautions, especially when there is concern for an AGP.
 

 

 

Universal masking: Risks and benefits

The idea of universal masking has been debated extensively since the initial stages of the COVID-19 pandemic. According to public health authorities, significant exposure is defined as “face-to-face contact within 6 feet with a patient with symptomatic COVID-19” in the range of a few minutes up to 30 minutes.5 The researchers wrote in the New England Journal of Medicine that the chance of catching COVID-19 from a passing interaction in a public space is therefore minimal, and it may seem unnecessary to wear a mask at all times in public.

Ruth Freshman

As reported in Science, randomized clinical studies performed on other viruses in the past have shown no added protection conferred by wearing a mask, though small sample sizes and noncompliance are limiting factors to their validity.6 On the contrary, mask wearing has been enforced in many parts of Asia, including Hong Kong and Singapore with promising results.5 Leung et al. stated in The Lancet that the lack of proof that masks are effective should not rule them as ineffective. Also, universal masking would reduce the stigma around symptomatic individuals covering their faces. It has become a cultural phenomenon in many southeast Asian countries and has been cited as one of the reasons for relatively successful containment in Singapore, South Korea, and Taiwan. The most important benefit of universal masking is protection attained by preventing spread from asymptomatic, mildly symptomatic, and presymptomatic carriers.7

In a study in the New England Journal of Medicine that estimated viral loads during various stages of COVID-19, researchers found that asymptomatic patients had similar viral loads to symptomatic patients, thereby suggesting high potential for transmission.8 Furthermore, numerous cases are being reported concerning the spread of illness from asymptomatic carriers.9-12 In an outbreak at a skilled nursing facility in Washington outlined in MMWR, 13 of 23 residents with positive test results were asymptomatic at the time of testing, and of those, 3 never developed any symptoms.12

Many hospitals are now embracing the policy of universal masking. A mask is a critical component of the personal protective equipment (PPE) clinicians need when caring for symptomatic patients with respiratory viral infections, in conjunction with a gown, gloves, and eye protection. Masking in this context is already part of routine operations in most hospitals. There are two scenarios in which there may be possible benefits. One scenario is the lower likelihood of transmission from asymptomatic and minimally symptomatic health care workers with COVID-19 to other providers and patients. The other less plausible benefit of universal masking among health care workers is that it may provide some protection in the possibility of caring for an unrecognized COVID-19 patient. However, universal masking should be coupled with other favorable practices like temperature checks and symptom screening on a daily basis to avail the maximum benefit from masking. Despite varied opinions on the outcomes of universal masking, this measure helps improve health care workers’ safety, psychological well-being, trust in their hospital, and decreases anxiety of acquiring the illness.
 

 

 

Efficacy of various types of masks

With the possibility of airborne transmission of the virus, are cloth masks as recommended by the CDC truly helpful in preventing infection? A study in the Journal of Medical Virology demonstrates 99.98%, 97.14%, and 95.15% efficacy for N95, surgical, and homemade masks, respectively, in blocking the avian influenza virus (comparable to coronavirus in size and physical characteristics). The homemade mask was created using one layer of polyester cloth and a four-layered kitchen filter paper.13

N95 masks (equivalent to FFP/P2 in European countries) are made of electrostatically charged polypropylene microfibers designed to filter particles measuring 100-300nm in diameter with 95% efficacy. A single SARS-CoV-2 molecule measures 125 nm approximately. N99 (FFP3) and N100 (P3) masks are also available, though not as widely used, with 99% and 99.7% efficacy respectively for the same size range. Though cloth masks are the clear-cut last resort for medical professionals, a few studies state no clinically proven difference in protection between surgical masks and N95 respirators.14,15 Even aerosolized droplets (< 5 mcm) were found to be blocked by surgical masks in a Nature Medicine study in which 4/10 subjects tested positive for coronavirus in exhaled breath samples without masks and 0/10 subjects with masks.16

On the contrary, an Annals of Internal Medicine study of four COVID-19 positive subjects that “neither surgical masks nor cloth masks effectively filtered SARS-CoV-2 during coughs of infected patients.” In fact, more contamination was found on the outer surface of the masks when compared to the inner surface, probably owing to the masks’ aerodynamic properties.17 Because of limitations present in the above-mentioned studies, further research is necessary to conclusively determine which types of masks are efficacious in preventing infection by the virus. In a scarcity of surgical masks and respirators for health care personnel, suboptimal masks can be of some use provided there is adherent use, minimal donning and doffing, and it is to be accompanied by adequate hand washing practices.14

In case of severe infections with high viral loads or patients undergoing aerosol-generating procedures, powered air-purifying respirators (PAPRs) also are advisable as they confer greater protection than N95 respirators, according to a study in the Annals of Work Exposures and Health. Despite being more comfortable for long-term use and accommodative of facial hair, their use is limited because of high cost and difficult maintenance.18 3-D printing also is being used to combat the current shortage of masks worldwide. However, a study from the International Journal of Oral & Maxillofacial Surgery reported that virologic testing for leakage between the two reusable components and contamination of the components themselves after one or multiple disinfection cycles is essential before application in real-life situations.19

Ongoing issues

WHO estimates a monthly requirement of nearly 90 million masks exclusively for health care workers to protect themselves against COVID-19.20 In spite of increasing the production rate by 40%, if the general public hoards masks and respirators, the results could be disastrous. Personal protective equipment is currently at 100 times the usual demand and 20 times the usual cost, with stocks backlogged by 4-6 months. The appropriate order of priority in distribution to health care professionals first, followed by those caring for infected patients is critical.20 In a survey conducted by the Association for Professionals in Infection Control and Epidemiology, results revealed that 48% of the U.S. health care facilities that responded were either out or nearly out of respirators as of March 25. 21

 

 

Dr. Raman Palabindala

The gravest risk behind the universal masking policy is the likely depletion of medical resources.22 A possible solution to this issue could be to modify the policy to stagger the requirement based on the severity of community transmission in that area of residence. In the article appropriately titled “Rational use of face masks in the COVID-19 pandemic” published in The Lancet Respiratory Medicine, researchers described how the Chinese population was classified into moderate, low, and very-low risk of infection categories and advised to wear a surgical or disposable mask, disposable mask, and no mask respectively.23 This curbs widespread panic and eagerness by the general public to stock up on essential medical equipment when it may not even be necessary.
 

Reuse, extended use, and sterilization

Several studies have been conducted to identify the viability of the COVID-19 on various surfaces.24-25 The CDC and National Institute for Occupational Safety and Health (NIOSH) guidelines state that an N95 respirator can be used up to 8 hours with intermittent or continuous use, though this number is not fixed and heavily depends upon the extent of exposure, risk of contamination, and frequency of donning and doffing26,27. Though traditionally meant for single-time usage, after 8 hours, the mask can be decontaminated and reused. The CDC defines extended use as the “practice of wearing the same N95 respirator for repeated close-contact encounters with several patients, without removing the respirator between patient encounters.” Reuse is defined as “using the same N95 respirator for multiple encounters with patients but removing it (‘doffing’) after each encounter. The respirator is stored in between encounters to be put on again (‘donned’) prior to the next encounter with a patient.”

It has been established that extended use is more advisable than reuse given the lower risk of self-inoculation. Furthermore, health care professionals are urged to wear a cleanable face shield or disposable mask over the respirator to minimize contamination and practice diligent hand hygiene before and after handling the respirator. N95 respirators are to be discarded following aerosol-generating procedures or if they come in contact with blood, respiratory secretions, or bodily fluids. They should also be discarded in case of close contact with an infected patient or if they cause breathing difficulties to the wearer.27 This may not always be possible given the unprecedented shortage of PPE, hence decontamination techniques and repurposing are the need of the hour.

In Anesthesia & Analgesia, Naveen Nathan, MD, of Northwestern University, Chicago, recommends recycling four masks in a series, using one per day, keeping the mask in a dry, clean environment, and then repeating use of the first mask on the 5th day, the second on the 6th day, and so forth. This ensures clearance of the virus particles by the next use. Alternatively, respirators can be sterilized between uses by heating to 70º C (158º F) for 30 minutes. Liquid disinfectants such as alcohol and bleach as well as ultraviolet rays in sunlight tend to damage masks.28 Steam sterilization is the most commonly utilized technique in hospitals. Other methods, described by the N95/PPE Working Group, report include gamma irradiation at 20kGy (2MRad) for large-scale sterilization (though the facilities may not be widely available), vaporized hydrogen peroxide, ozone decontamination, ultraviolet germicidal irradiation, and ethylene oxide.29 Though a discussion on various considerations of decontamination techniques is out of the scope of this article, detailed guidelines have been published by the CDC30 and the COVID-19 Healthcare Coalition.30

COVID-19 in kids
Children and young adults in all age groups can develop severe illess after SARS-CoV-2 infection, but infants and teens are most likely to be hospitalized, according to retrospective data from 177 children and young adults at a single center. “One patient had features consistent with the recently emerged Kawasaki disease–like presentation with hyperinflammatory state, hypotension, and profound myocardial depression,” Roberta L. DeBiasi, MD, of Children’s National Hospital, Washington, and colleagues reported in the Journal of Pediatrics. READ MORE

Avoiding ageism in COVID resource allocation
The American Geriatrics Society has issued new policy recommendations for resource allocation during the COVID-19 pandemic that are aimed at protecting seniors for ageism. When allocating scarce resources in an emergency, officials should equally weigh in-hospital survival and severe comorbidities contributing to short-term mortality, the group wrote. “Age per se should never be used as a means for a categorical exclusion from therapeutic interventions that represent the standard of care. ... Likewise, specific age-based cutoffs should not be used in resource allocation strategies,” AGS officials wrote in the statement. READ MORE

Preventing addiction-related suicide
Individuals with substance use disorders are at a significant risk for suicide, but there have been few evidence-based options for their treatment. Now a single intervention is showing promise for this high-risk group. In a large, multicenter randomized effectiveness study, a single 3-hour-long group psychosocial intervention resulted in significantly improved knowledge and attitudes regarding suicide that persisted at 6 months of follow-up. The intervention to prevent future suicide was designed specifically for patients who were in intensive outpatient programs for addiction treatment. “We’ve shown that suicide prevention in intensive outpatient program addiction groups is feasible, easy to train, and highly rated by counselors, and I’d say it’s very adaptable, easy to go national in almost any addiction treatment program, right out of the box,” said Richard K. Ries, MD, director of outpatient psychiatry as well as the psychiatry addiction division at Harborview Medical Center. READ MORE

TNF inhibitors may hamper COVID-19 severity
Early evidence from the COVID-19 Global Rheumatology Alliance Registry has produced an intriguing result: Patients on tumor necrosis factor inhibitors for their rheumatic disease are less likely to require hospitalization when infected with COVID-19. The registry data also show that taking hydroxychloroquine or other antimalarials at the time of COVID-19 infection had no impact on hospitalization. “A strength of the global registry has been that it provides timely data that’s been very helpful for rheumatologists to rapidly dispel misinformation that has been spread about hydroxychloroquine, especially statements about lupus patients not getting COVID-19. We know from these data that’s not true,” said Jinoos Yazdany, MD, professor of medicine at the University of California, San Francisco, and chief of rheumatology at San Francisco General Hospital.

Audrey Hepburn’s lessons in pandemic grace
There are a lot of new skills required for praticing medicine during the COVID-19 pandemic. In his latest MDedge column, Jeffrey Benabio, MD, explains that grace is one of them. Dr. Benabio, director of Healthcare Transformation and chief of dermatology at Kaiser Permanente San Diego, looks to Audrey Hepburn for inspiration. “Effort is also required for telephone and video visits,” he writes. “In them, our doctor-patient connection is diminished – no matter how high definition, it’s a virtual affair. Ms. Hepburn would no doubt take the time to ensure she appeared professional, well lit, with a pleasing background. She’d plan for the call to be done in a quiet location and without distraction.” READ MORE

COVID-19 in kids
Children and young adults in all age groups can develop severe illess after SARS-CoV-2 infection, but infants and teens are most likely to be hospitalized, according to retrospective data from 177 children and young adults at a single center. “One patient had features consistent with the recently emerged Kawasaki disease–like presentation with hyperinflammatory state, hypotension, and profound myocardial depression,” Roberta L. DeBiasi, MD, of Children’s National Hospital, Washington, and colleagues reported in the Journal of Pediatrics. READ MORE

AGS issues pandemic resource allocation recommendations amid ageism concerns

Article Type
Changed
Thu, 08/26/2021 - 16:07

The American Geriatrics Society has issued policy recommendations aimed at protecting seniors from ageism when it comes to resource allocation in the current context of treating patients infected with COVID-19.

Dr. Timothy W. Farrell

“The AGS is deeply concerned about potentially negative long-term consequences of COVID-19 emergency rationing strategies that disfavor older adults,” Timothy W. Farrell, MD, University of Utah, Salt Lake City, and colleagues wrote in an AGS position statement published online in the Journal of the American Geriatrics Society.

“In particular, rationing strategies that are solely, or predominantly, based on age cutoffs could lead to persistent beliefs that older adults’ lives are less valuable than others or are even expendable, and contribute to already rampant ageism,” the authors continued. “Unless the injustice in these strategies is corrected, this will be a persistent issue if there is a resurgence of COVID-19 cases, a pandemic caused by a different virus in the future, or a different type of disaster where resources are scarce.”

To counter a potential bias against the elderly population should scarce resources force rationing decisions, AGS has made recommendations and strategies that health care systems should incorporate into a policy framework.

One principle in the AGS statement is clear: “Age per se should never be used as a means for a categorical exclusion from therapeutic interventions that represent the standard of care. ... Likewise, specific age-based cutoffs should not be used in resource allocation strategies.”

Peter Angelos, MD, chief of endocrine surgery at the University of Chicago, applauded the position statement.

Dr. Peter Angelos

“It is a well-written statement and I do think that it appropriately suggests that age in and of itself is not a good predictor of who is at greatest risk if infected with coronavirus,” Dr. Angelos, who also serves as the associate director of the MacLean Center for Clinical Medical Ethics, said in an interview.

He suggested a scenario in which a younger person could have multiple comorbidities that could put that individual at a higher risk of death because of complications from COVID-19 (or another pandemic in the future), compared with an older patient who is otherwise a healthy individual with a lower risk of death.

“For that reason, I agree with the authors that there should not be an arbitrary cutoff of age for which we don’t treat people or we limit treatment.”

Rather, the authors state that the primary allocation method in emergency circumstances that require rationing because of lack of resources should “equally weigh in-hospital survival and severe comorbidities contributing to short-term (<6 months) mortality.”

When assessing comorbidities, “the disparate impact of social determinants of health including culture, ethnicity, socioeconomic status, and other factors should be considered.”

AGS’s position statement adds that criteria such as “life-years saved” and “long-term predicted life expectancy” should not be used as they tend to disadvantage older adults.

The organization noted that institutions “should develop resource allocation strategies that are transparent, applied uniformly, and developed with forethought and input from multiple disciplines including ethics, medicine, law, and nursing. These strategies should be used consistently when making emergency decisions.” The AGS called for institutions to frequently review these strategies to ensure they are updated with the most recent evidence and to identify any issues of bias that may emerge.

Dr. Angelos stressed that these guidelines should be developed in a transparent and open fashion. He also highlighted the AGS recommendation of the use of triage officers or triage committees to make the determination about resource allocation should those decisions need to be made.

“We don’t want caregivers who are at the bedside taking care of patients to have the responsibility to say ‘We are going to treat one person as opposed to another person,’ ” he said. “You want to have those decisions made by a team that is separate from the bedside caregivers.”

He agreed with the statement authors that the goal of the triage committee decisions should be to maximize lives saved as opposed to life-years saved. Dr. Angelos noted that his institution’s plan focuses on lives saved should the need for resource rationing come to pass.

In addition to institutional strategies, AGS also emphasized in the position statement that older adults should develop individual care plans that include lists of medical conditions, medications, health care providers, and advance directives. The statement also noted that about only 50% of adults over age 60 years have complete advance directives, a rate Dr. Farrell and colleagues state is “unacceptably low.”

“Advance care planning should not be limited to the purview of only the primary care, geriatrics, or palliative care health professional, and urgent efforts should be made to discuss patient preferences before an emergent need arises,” the paper states, noting that specialists need to be a part of the conversation.

However, the position statement is clear that, while AGS is encouraging providers to talk about advance care planning with their patients, “providers should not pressure, even subtly, patients to engage in advance care planning or change to Do Not Resuscitate/Do Not Intubate (DNR/DNI) status with the intent to conserve health resources.”

Dr. Angelos reiterated this point and suggested that advance directive conversations need to be happening and happening more often.

“This current pandemic has forced us all to realize that, even in well-resourced societies like the United States, we may be faced with situations of absolute scarcity, so we ought to have these conversations up front so that we are not put in a position where we have to make decisions, and those decisions may not be well thought out and may not be ethically justifiable,” he said.

Audrey Hepburn’s lessons for a COVID clinic

Article Type
Changed
Thu, 08/26/2021 - 16:07

From the ash of our post “coron-apocalyptic” world, we emerge. It’s back to work, to life in a new normal. Patients are still scarce and scared, as are some doctors. Queues of patients wait to clear security and enter the sterile area at every medical office. Water bottles are allowed, fevers and visitors are not. Those who fail clearance or who are afraid to be seen in person must be treated virtually. In this context, virtually means by telephone or video, yet, aptly, it also means “nearly or almost,” as in we can nearly or almost treat them these ways. We’ve emerged safely, but we’ve lost sensibility. Because of this, what’s important in the doctor-patient relationships will drift a bit. Clinical acumen and technical skill won’t be enough. Successful practices will also have grace.

If your image of grace is Audrey Hepburn gliding along Fifth Avenue in a long black dress and elbow-length gloves, you’re in the right place. Ms. Hepburn embodied elegance and decorum and there are lessons to be drawn from her. Piling your hair high and donning oversized sunglasses along with your face mask would be to miss the point here though. Ms. Hepburn dressed exquisitely, yes, but her grace came from what wearing a difficult-to-walk-in dress meant to us, not to her. Appearance, self-control, and warmth are what made her charismatic.



To appear urbane requires effort; it’s the effort that we appreciate in someone who is graceful. When you’re thoughtful about how you look, you plan ahead, you work to look polished. In effect, you’re saying: “As my patient, you’re important enough for me to be well dressed.” It is a visible signal of all the unobservable work you’ve done to care for them. This is more critical now that our faces are covered and concern for infection means wearing shabby hospital scrubs rather than shirt and tie.

Effort is also required for telephone and video visits. In them, our doctor-patient connection is diminished – no matter how high definition, it’s a virtual affair. Ms. Hepburn would no doubt take the time to ensure she appeared professional, well lit, with a pleasing background. She’d plan for the call to be done in a quiet location and without distraction.

Whether in person or by phone, grace, as Ms. Hepburn demonstrated, is physical awareness and body control. She would often be completely still when someone is speaking, showing a countenance of warmth. She’d pause after the other person completed a thought and before replying. In doing so, she conveyed that she was present and engaged in what was being said. It is that confidence and ease of manner we perceived as grace.

Dr. Jeffrey Benabio

I thought about this the other day during a mixed clinic of telephone and face-to-face visits. I had on my wrinkle-free scrubs (I could do better). I was listening to a patient describe all possible triggers for her hand dermatitis. My urge to interrupt grew with each paragraph of her storytelling. “Be patient,” I thought, “be at ease with her rambling. ... When she stops, thank her as if you were looking her in the eye acknowledging how interesting her observations were.” This is not just good manners, it’s the essence of grace: The art of showing how important others are to you.

Our world needs grace more than ever and what better place to start but with us. In pleasing, assisting, and honoring them, our patients can be reassured that we can and will care for them. Make Ms. Hepburn proud.

“For beautiful eyes, look for the good in others; for beautiful lips, speak only words of kindness; and for poise, walk with the knowledge that you are never alone.” – Audrey Hepburn

From the ash of our post “coron-apocalyptic” world, we emerge. It’s back to work, to life in a new normal. Patients are still scarce and scared, as are some doctors. Queues of patients wait to clear security and enter the sterile area at every medical office. Water bottles are allowed, fevers and visitors are not. Those who fail clearance or who are afraid to be seen in person must be treated virtually. In this context, virtually means by telephone or video, yet, aptly, it also means “nearly or almost,” as in we can nearly or almost treat them these ways. We’ve emerged safely, but we’ve lost sensibility. Because of this, what’s important in the doctor-patient relationships will drift a bit. Clinical acumen and technical skill won’t be enough. Successful practices will also have grace.

If your image of grace is Audrey Hepburn gliding along Fifth Avenue in a long black dress and elbow-length gloves, you’re in the right place. Ms. Hepburn embodied elegance and decorum and there are lessons to be drawn from her. Piling your hair high and donning oversized sunglasses along with your face mask would be to miss the point here though. Ms. Hepburn dressed exquisitely, yes, but her grace came from what wearing a difficult-to-walk-in dress meant to us, not to her. Appearance, self-control, and warmth are what made her charismatic.



To appear urbane requires effort; it’s the effort that we appreciate in someone who is graceful. When you’re thoughtful about how you look, you plan ahead, you work to look polished. In effect, you’re saying: “As my patient, you’re important enough for me to be well dressed.” It is a visible signal of all the unobservable work you’ve done to care for them. This is more critical now that our faces are covered and concern for infection means wearing shabby hospital scrubs rather than shirt and tie.

Effort is also required for telephone and video visits. In them, our doctor-patient connection is diminished – no matter how high definition, it’s a virtual affair. Ms. Hepburn would no doubt take the time to ensure she appeared professional, well lit, with a pleasing background. She’d plan for the call to be done in a quiet location and without distraction.

Whether in person or by phone, grace, as Ms. Hepburn demonstrated, is physical awareness and body control. She would often be completely still when someone is speaking, showing a countenance of warmth. She’d pause after the other person completed a thought and before replying. In doing so, she conveyed that she was present and engaged in what was being said. It is that confidence and ease of manner we perceived as grace.

I thought about this the other day during a mixed clinic of telephone and face-to-face visits. I had on my wrinkle-free scrubs (I could do better). I was listening to a patient describe all possible triggers for her hand dermatitis. My urge to interrupt grew with each paragraph of her storytelling. “Be patient,” I thought, “be at ease with her rambling. ... When she stops, thank her as if you were looking her in the eye acknowledging how interesting her observations were.” This is not just good manners, it’s the essence of grace: The art of showing how important others are to you.

Our world needs grace more than ever and what better place to start but with us. In pleasing, assisting, and honoring them, our patients can be reassured that we can and will care for them. Make Ms. Hepburn proud.

Vitamin D: A low-hanging fruit in COVID-19?

Article Type

Thu, 08/26/2021 - 16:07

Mainstream media outlets have been flooded recently with reports speculating on what role, if any, vitamin D may play in reducing the severity of COVID-19 infection.

Observational data comparing outcomes from various countries suggest inverse links between vitamin D levels and the severity of COVID-19 responses, as well as mortality, with the further suggestion of an effect of vitamin D on the immune response to infection.

But other studies question such a link, including any association between vitamin D concentration and differences in COVID-19 severity by ethnic group.

And while some researchers and clinicians believe people should get tested to see if they have adequate vitamin D levels during this pandemic – in particular frontline health care workers – most doctors say the best way to ensure that people have adequate levels of vitamin D during COVID-19 is to simply take supplements at currently recommended levels.

This is especially important given the fact that, during “lockdown” scenarios, many people are spending more time than usual indoors.

Clifford Rosen, MD, senior scientist at Maine Medical Center’s Research Institute in Scarborough, has been researching vitamin D for 25 years.

“There’s no randomized, controlled trial for sure, and that’s the gold standard,” he said in an interview, and “the observational data are so confounded, it’s difficult to know.”

Whether from diet or supplementation, having adequate vitamin D is important, especially for those at the highest risk of COVID-19, he said. Still, robust data supporting a role of vitamin D in prevention of COVID-19, or as any kind of “therapy” for the infection, are currently lacking.

Rose Anne Kenny, MD, professor of medical gerontology at Trinity College Dublin, recently coauthored an article detailing an inverse association between vitamin D levels and mortality from COVID-19 across countries in Europe.

“At no stage are any of us saying this is a given, but there’s a probability that [vitamin D] – a low-hanging fruit – is a contributory factor and we can do something about it now,” she said in an interview.

Dr. Kenny is calling for the Irish government to formally change their recommendations. “We call on the Irish government to update guidelines as a matter of urgency and encourage all adults to take [vitamin D] supplements during the COVID-19 crisis.” Northern Ireland, part of the United Kingdom, also has not yet made this recommendation, she said.

Meanwhile, Harpreet S. Bajaj, MD, MPH, a practicing endocrinologist from Mount Sinai Hospital, Toronto, said: “Vitamin D could have any of three potential roles in risk for COVID-19 and/or its severity: no role, simply a marker, or a causal factor.”

Dr. Bajaj said – as did Dr. Rosen and Dr. Kenny – that randomized, controlled trials (RCTs) are sorely needed to help ascertain whether there is a specific role of vitamin D.

“Until then, we should continue to follow established public health recommendations for vitamin D supplementation, in addition to following COVID-19 prevention guidance and evolving guidelines for COVID-19 treatment.”
 

What is the role of vitamin D fortification?

In their study in the Irish Medical Journal, Dr. Kenny and colleagues noted that, in Europe, despite being sunny, Spain and Northern Italy had high rates of vitamin D deficiency and have experienced some of the highest COVID-19 infection and mortality rates in the world.

But these countries do not formally fortify foods or recommend supplementation with vitamin D.

Conversely, the northern countries of Norway, Finland, and Sweden had higher vitamin D levels despite less UVB sunlight exposure, as a result of common supplementation and formal fortification of foods. These Nordic countries also had lower levels of COVID-19 infection and mortality.

Overall, the correlation between low vitamin D levels and mortality from COVID-19 was statistically significant (P = .046), the investigators reported.

“Optimizing vitamin D status to recommendations by national and international public health agencies will certainly have ... potential benefits for COVID-19,” they concluded.

“We’re not saying there aren’t any confounders. This can absolutely be the case, but this [finding] needs to be in the mix of evidence,” Dr. Kenny said.

Dr. Kenny also noted that countries in the Southern Hemisphere have been seeing a relatively low mortality from COVID-19, although she acknowledged the explanation could be that the virus spread later to those countries.

Dr. Rosen has doubts on this issue, too.

“Sure, vitamin D supplementation may have worked for [Nordic countries], their COVID-19 has been better controlled, but there’s no causality here; there’s another step to actually prove this. Other factors might be at play,” he said.

“Look at Brazil, it’s at the equator but the disease is devastating the country. Right now, I just don’t believe it.”

Does vitamin D have a role to play in immune modulation?

One theory currently circulating is that, if vitamin D does have any role to play in modulating response to COVID-19, this may be via a blunting of the immune system reaction to the virus.

In a recent preprint study, Ali Daneshkhah, PhD, and colleagues from Northwestern University, Chicago, interrogated hospital data from China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the United Kingdom, and the United States.

Specifically, the risk of severe COVID-19 cases among patients with severe vitamin D deficiency was 17.3%, whereas the equivalent figure for patients with normal vitamin D levels was 14.6% (a reduction of 15.6%).

“This potential effect may be attributed to vitamin D’s ability to suppress the adaptive immune system, regulating cytokine levels and thereby reducing the risk of developing severe COVID-19,” said the researchers.

Likewise, JoAnn E. Manson, MD, chief of the division of preventive medicine at Brigham and Women’s Hospital in Boston, in a recent commentary, noted evidence from an observational study from three South Asian hospitals, in which the prevalence of vitamin D deficiency was much higher among those with severe COVID-19 illness compared with those with mild illness.

“We also know that vitamin D has an immune-modulating effect and can lower inflammation, and this may be relevant to the respiratory response during COVID-19 and the cytokine storm that’s been demonstrated,” she noted.

Dr. Rosen said he is willing to listen on the issue of a potential role of vitamin D in immune modulation.

“I’ve been a huge skeptic from the get-go, and loudly criticized the data for doing nothing. I am surprised at myself for saying there might be some effect,” he said.

“Clearly most people don’t get this [cytokine storm] but of those that do, it’s unclear why they do. Maybe if you are vitamin D sufficient, it might have some impact down the road on your response to an infection,” Dr. Rosen said. “Vitamin D may induce proteins important in modulating the function of macrophages of the immune system.”

 

 

Ethnic minorities disproportionately affected

It is also well recognized that COVID-19 disproportionately affects black and Asian minority ethnic individuals.

But on the issue of vitamin D in this context, one recent peer-reviewed study using UK Biobank data found no evidence to support a potential role for vitamin D concentration to explain susceptibility to COVID-19 infection either overall or in explaining differences between ethnic groups.

“Vitamin D is unlikely to be the underlying mechanism for the higher risk observed in black and minority ethnic individuals, and vitamin D supplements are unlikely to provide an effective intervention,” Claire Hastie, PhD, of the University of Glasgow and colleagues concluded.

But this hasn’t stopped two endocrinologists from appealing to members of the British Association of Physicians of Indian Origin (BAPIO) to get their vitamin D levels tested.

The black and Asian minority ethnic population, “especially frontline staff, should get their Vitamin D3 levels checked and get appropriate replacement as required,” said Parag Singhal, MD, of Weston General Hospital, Weston-Super-Mare, England, and David C. Anderson, a retired endocrinologist, said in a letter to BAPIO members.

Indeed, they suggested a booster dose of 100,000 IU as a one-off for black and Asian minority ethnic health care staff that should raise vitamin D levels for 2-3 months. They referred to a systematic review that concludes that “single vitamin D3 doses ≥300,000 IU are most effective at improving vitamin D status ... for up to 3 months”.

Commenting on the idea, Dr. Rosen remarked that, in general, the high-dose 50,000-500,000 IU given as a one-off does not confer any greater benefit than a single dose of 1,000 IU per day, except that the blood levels go up quicker and higher.

“Really there is no evidence that getting to super-high levels of vitamin D confer a greater benefit than normal levels,” he said. “So if health care workers suspect vitamin D deficiency, daily doses of 1,000 IU seem reasonable; even if they miss doses, the blood levels are relatively stable.”

On the specific question of vitamin D needs in ethnic minorities, Dr. Rosen said while such individuals do have lower serum levels of vitamin D, the issue is whether there are meaningful clinical implications related to this.

“The real question is whether [ethnic minority individuals] have physiologically adapted for this in other ways because these low levels have been so for thousands of years. In fact, African Americans have lower vitamin D levels but they absolutely have better bones than [whites],” he pointed out. 
 

Testing and governmental recommendations during COVID-19

The U.S. National Institutes of Health in general advises 400 IU to 800 IU per day intake of vitamin D, depending on age, with those over 70 years requiring the highest daily dose. This will result in blood levels that are sufficient to maintain bone health and normal calcium metabolism in healthy people. There are no additional recommendations specific to vitamin D intake during the COVID-19 pandemic, however.

And Dr. Rosen pointed out that there is no evidence for mass screening of vitamin D levels among the U.S. population.

“U.S. public health guidance was pre-COVID, and I think high-risk individuals might want to think about their levels; for example, someone with inflammatory bowel disease or liver or pancreatic disease. These people are at higher risk anyway, and it could be because their vitamin D is low,” he said.

“Skip the test and ensure you are getting adequate levels of vitamin D whether via diet or supplement [400-800 IU per day],” he suggested. “It won’t harm.”

The U.K.’s Public Health England (PHE) clarified its advice on vitamin D supplementation during COVID-19. Alison Tedstone, PhD, chief nutritionist at PHE, said: “Many people are spending more time indoors and may not get all the vitamin D they need from sunlight. To protect their bone and muscle health, they should consider taking a daily supplement containing 10 micrograms [400 IU] of vitamin D.”

However, “there is no sufficient evidence to support recommending Vitamin D for reducing the risk of COVID-19,” she stressed.

He has ties with Amgen, AstraZeneca Boehringer Ingelheim, Janssen, Merck, Novo Nordisk, Sanofi, Eli Lilly,Valeant, Canadian Collaborative Research Network, CMS Knowledge Translation, Diabetes Canada Scientific Group, LMC Healthcare,mdBriefCase,Medscape, andMeducom. Dr. Kenny, Dr. Rosen, and Dr. Singhal have disclosed no relevant financial relationships.

Indeed, they suggested a booster dose of 100,000 IU as a one-off for black and Asian minority ethnic health care staff that should raise vitamin D levels for 2-3 months. They referred to a systematic review that concludes that “single vitamin D3 doses ≥300,000 IU are most effective at improving vitamin D status ... for up to 3 months”.

Commenting on the idea, Dr. Rosen remarked that, in general, the high-dose 50,000-500,000 IU given as a one-off does not confer any greater benefit than a single dose of 1,000 IU per day, except that the blood levels go up quicker and higher.

“Really there is no evidence that getting to super-high levels of vitamin D confer a greater benefit than normal levels,” he said. “So if health care workers suspect vitamin D deficiency, daily doses of 1,000 IU seem reasonable; even if they miss doses, the blood levels are relatively stable.”

On the specific question of vitamin D needs in ethnic minorities, Dr. Rosen said while such individuals do have lower serum levels of vitamin D, the issue is whether there are meaningful clinical implications related to this.

“The real question is whether [ethnic minority individuals] have physiologically adapted for this in other ways because these low levels have been so for thousands of years. In fact, African Americans have lower vitamin D levels but they absolutely have better bones than [whites],” he pointed out. 
 

Testing and governmental recommendations during COVID-19

The U.S. National Institutes of Health in general advises 400 IU to 800 IU per day intake of vitamin D, depending on age, with those over 70 years requiring the highest daily dose. This will result in blood levels that are sufficient to maintain bone health and normal calcium metabolism in healthy people. There are no additional recommendations specific to vitamin D intake during the COVID-19 pandemic, however.

And Dr. Rosen pointed out that there is no evidence for mass screening of vitamin D levels among the U.S. population.

“U.S. public health guidance was pre-COVID, and I think high-risk individuals might want to think about their levels; for example, someone with inflammatory bowel disease or liver or pancreatic disease. These people are at higher risk anyway, and it could be because their vitamin D is low,” he said.

“Skip the test and ensure you are getting adequate levels of vitamin D whether via diet or supplement [400-800 IU per day],” he suggested. “It won’t harm.”

The U.K.’s Public Health England (PHE) clarified its advice on vitamin D supplementation during COVID-19. Alison Tedstone, PhD, chief nutritionist at PHE, said: “Many people are spending more time indoors and may not get all the vitamin D they need from sunlight. To protect their bone and muscle health, they should consider taking a daily supplement containing 10 micrograms [400 IU] of vitamin D.”

However, “there is no sufficient evidence to support recommending Vitamin D for reducing the risk of COVID-19,” she stressed.

TNF inhibitors may dampen COVID-19 severity

Article Type

Tue, 02/07/2023 - 16:49

Patients on a tumor necrosis factor inhibitor for their rheumatic disease when they became infected with COVID-19 were markedly less likely to subsequently require hospitalization, according to intriguing early evidence from the COVID-19 Global Rheumatology Alliance Registry.

Dr. Jinoos Yazdany

On the other hand, those registry patients who were on 10 mg of prednisone or more daily when they got infected were more than twice as likely to be hospitalized than were those who were not on corticosteroids, even after controlling for the severity of their rheumatic disease and other potential confounders, Jinoos Yazdany, MD, reported at the virtual edition of the American College of Rheumatology’s 2020 State-of-the-Art Clinical Symposium.

“We saw a signal with moderate to high-dose steroids. I think it’s something we’re going to have to keep an eye out on as more data come in,” said Dr. Yazdany, professor of medicine at the University of California, San Francisco, and chief of rheumatology at San Francisco General Hospital.

The global registry launched on March 24, 2020, and was quickly embraced by rheumatologists from around the world. By May 12, the registry included more than 1,300 patients with a range of rheumatic diseases, all with confirmed COVID-19 infection as a requisite for enrollment; the cases were submitted by more than 300 rheumatologists in 40 countries. The registry is supported by the ACR and European League Against Rheumatism.

Dr. Yazdany, a member of the registry steering committee, described the project’s two main goals: To learn the outcomes of COVID-19–infected patients with various rheumatic diseases and to make inferences regarding the impact of the immunosuppressive and antimalarial medications widely prescribed by rheumatologists.

She presented soon-to-be-published data on the characteristics and disposition of the first 600 patients, 46% of whom were hospitalized and 9% died. A caveat regarding the registry, she noted, is that these are observational data and thus potentially subject to unrecognized confounders. Also, the registry population is skewed toward the sicker end of the COVID-19 disease spectrum because while all participants have confirmed infection, testing for the infection has been notoriously uneven. Many people are infected asymptomatically and thus may not undergo testing even where readily available.
 

Early key findings from registry

The risk factors for more severe infection resulting in hospitalization in patients with rheumatic diseases are by and large the same drivers described in the general population: older age and comorbid conditions including diabetes, hypertension, cardiovascular disease, obesity, chronic kidney disease, and lung disease. Notably, however, patients on the equivalent of 10 mg/day of prednisone or more were at a 105% increased risk for hospitalization, compared with those not on corticosteroids after adjustment for age, comorbid conditions, and rheumatic disease severity.

Patients on a background tumor necrosis factor (TNF) inhibitor had an adjusted 60% reduction in risk of hospitalization. This apparent protective effect against more severe COVID-19 disease is mechanistically plausible: In animal studies, being on a TNF inhibitor has been associated with less severe infection following exposure to influenza virus, Dr. Yazdany observed.

COVID-infected patients on any biologic disease-modifying antirheumatic drug had a 54% decreased risk of hospitalization. However, in this early analysis, the study was sufficiently powered only to specifically assess the impact of TNF inhibitors, since those agents were by far the most commonly used biologics. As the registry grows, it will be possible to analyze the impact of other antirheumatic medications.

Being on hydroxychloroquine or other antimalarials at the time of COVID-19 infection had no impact on hospitalization.

The only rheumatic disease diagnosis with an odds of hospitalization significantly different from that of RA patients was systemic lupus erythematosus (SLE). Lupus patients were at 80% increased risk of hospitalization. Although this was a statistically significant difference, Dr. Yazdany cautioned against making too much of it because of the strong potential for unmeasured confounding. In particular, lupus patients as a group are known to rate on the lower end of measures of social determinants of health, a status that is an established major risk factor for COVID-19 disease.

“A strength of the global registry has been that it provides timely data that’s been very helpful for rheumatologists to rapidly dispel misinformation that has been spread about hydroxychloroquine, especially statements about lupus patients not getting COVID-19. We know from these data that’s not true,” she said.

Being on background NSAIDs at the time of SARS-CoV-2 infection was not associated with increased risk of hospitalization; in fact, NSAID users were 36% less likely to be hospitalized for their COVID-19 disease, although this difference didn’t reach statistical significance.

Dr. Yazdany urged her fellow rheumatologists to enter their cases on the registry website: rheum-covid.org. There they can also join the registry mailing list and receive weekly updates.
 

 

 

Other recent insights on COVID-19 in rheumatology

An as-yet unpublished U.K. observational study involving electronic health record data on 17 million people included 885,000 individuals with RA, SLE, or psoriasis. After extensive statistical controlling for the known risk factors for severe COVID-19 infection, including a measure of socioeconomic deprivation, the group with one of these autoimmune diseases had an adjusted, statistically significant 23% increased risk of hospital death because of COVID-19 infection.

“This is the largest study of its kind to date. There’s potential for unmeasured confounding and selection bias here due to who gets tested. We’ll have to see where this study lands, but I think it does suggest there’s a slightly higher mortality risk in COVID-infected patients with rheumatic disease,” according to Dr. Yazdany.



On the other hand, there have been at least eight recently published patient surveys and case series of patients with rheumatic diseases in areas of the world hardest hit by the pandemic, and they paint a consistent picture.

“What we’ve learned from these studies was the infection rate was generally in the ballpark of people in the region. It doesn’t seem like there’s a dramatically higher infection rate in people with rheumatic disease in these surveys. The hospitalized rheumatology patients had many of the familiar comorbidities. This is the first glance at how likely people are to become infected and how they fared, and I think overall the data have been quite reassuring,” she said.

Dr. Yazdany reported serving as a consultant to AstraZeneca and Eli Lilly and receiving research funding from the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Centers for Disease Control and Prevention.

Antibody testing suggests COVID-19 cases are being missed

Article Type

The number of COVID-19 infections in the community may be “substantially greater” than totals confirmed by authorities, based on SARS-CoV-2 antibody testing among a random sample of adults in Los Angeles County, Calif.

Testing of 863 people on April 10-11 revealed that 35 (4.06%) were positive for SARS-CoV-2–specific antibodies (IgM or IgG), and after adjustment for test sensitivity and specificity, the weighted prevalence for the entire sample was 4.65%, Neeraj Sood, PhD, of the University of Southern California, Los Angeles, and associates wrote in JAMA.

The estimate of 4.65% “implies that approximately 367,000 adults [in Los Angeles County] had SARS-CoV-2 antibodies, which is substantially greater than the 8,430 cumulative number of confirmed infections in the county on April 10,” they wrote.

It also suggests that fatality rates based on the larger number of infections may be lower than rates based on confirmed cases. “In addition, contact tracing methods to limit the spread of infection will face considerable challenges,” Dr. Sood and associates said.



Test positivity varied by race/ethnicity, sex, and income. The proportion of non-Hispanic blacks with a positive result was 6.94%, compared with 4.42% for non-Hispanic whites, 2.10% for Hispanics, and 3.85% for others. Men were much more likely than women to be positive for SARS-CoV-2: 5.18% vs. 3.31%, the investigators said.

Household income favored the middle ground. Those individuals making less than $50,000 a year had a positivity rate of 5.14% and those with an income of $100,000 or more had a rate of 4.90%, but only 1.58% of those making $50,000-$99,999 tested positive, they reported.

The authors reported numerous sources of nonprofit organization support.
