Global study to track COVID-19’s impact on the brain
At its annual meeting, the Alzheimer’s Association announced the launch of a global study to examine the impact of COVID-19 on the brain, as well as policy recommendations to better address the COVID-19 crisis in long-term care facilities. The study will be led by researchers at the Alzheimer’s Association and the University of Texas Health, San Antonio, with participation from more than 30 countries and technical guidance from the World Health Organization.
The target sample size is 20,000-40,000 total participants.
Maria C. Carrillo, PhD, chief science officer for the Alzheimer’s Association, announced the study’s launch during a COVID-19–focused panel discussion at the virtual annual meeting of the Alzheimer’s Association International Conference 2020.
“To build a strong foundation for this research, we will align with existing studies, such as the Framingham Heart Study, and clinicians from around the world on how the data are going to be collected, obtained, and shared. We are going to have cross-study collaborations to understand the impact of the virus on the brain directly,” said Dr. Carrillo. “We will have some very good data to present next year at AAIC.”
‘Frightening’ headlines
As previously reported, mounting evidence suggests that SARS-CoV-2 invades the central nervous system, causing a wide range of neurologic and neuropsychiatric complications, including stroke, psychosis, altered mental state, and dementia-like syndrome. It’s likely that “dementia does not increase the risk for COVID-19, just like dementia does not increase risk for the flu. But increased age, being in a long-term care setting, and common health conditions that often accompany dementia may increase the risk,” Dr. Carrillo said.
Panel member Beth Kallmyer, MSW, vice president of care and support at the Alzheimer’s Association, spoke about the ongoing challenges long-term care facilities are facing during the pandemic. “You’ve all seen the headlines, and they’re frightening, frankly,” she said. An estimated 59,000 residents and employees of long-term care have died as a result of COVID-19, which is 42% of all U.S. deaths.
The long-term care community is being impacted at “significantly greater rates than the rest of society and yet we don’t have things in place to protect them. We also know that individuals living with dementia make up a large percentage of those that are living in long-term care,” Ms. Kallmyer said.
She noted that infection control is always a challenge in long-term care settings, but infection control during a pandemic “takes it to a whole other level.” Quarantining is hard for anyone, “but when you layer dementia on top of that we have a real challenge.” One long-term care provider told Ms. Kallmyer that “we might be saving them from COVID, but we’re losing them to social isolation and cognitive decline.”
New recommendations
Ms. Kallmyer outlined new policy recommendations from the Alzheimer’s Association to address the COVID-19 crisis in long-term and community-based care settings. They include:
- Testing every resident, employee, and visitor each time they leave and come back, so residents would not need to be confined to their own rooms
- Having a single portal that is easy and efficient for reporting cases
- Developing “surge activation” protocols to respond to hot spots, including the possibility of “strike teams” that go in and help during an outbreak
- Making sure all long-term care providers have full access to all needed personal protective equipment (PPE)
“Five months in and long-term care providers still don’t have adequate PPE. This is unacceptable,” said Ms. Kallmyer. “We have to be able to provide them with PPE.”
Panel member Gregory A. Jicha, MD, PhD, Sanders-Brown Center on Aging, University of Kentucky, Lexington, spoke about the critical need to continue Alzheimer’s disease research during the pandemic, noting that the number of promising targets for Alzheimer’s disease and related dementias has “never been higher or more comprehensive.”
Measures to ensure safety of researchers and participants include screening for symptoms (50% effective), social distancing (93% effective), minimizing exposure time (50% effective), limiting staff to 50% (50% effective), cloth/paper masks (80% effective), and testing (99.25% effective), Dr. Jicha noted.
With no safety measures in place, the risk of getting COVID-19 from a research visit is 1 in 20; when all these safety measures are combined, the risk is 1 in over 1.5 million, so “we can essentially eradicate or minimize the risks for COVID to less that of a lightning strike,” he said.
Dr. Carrillo, Ms. Kallmyer, and Dr. Jicha disclosed no relevant financial relationships.

COVID-19 taking financial toll on people in U.S. with diabetes
The COVID-19 pandemic is taking a particularly severe financial toll on people with diabetes, new research from the United States suggests.
Results from a national online survey of 5,000 people with diabetes conducted between June 26 and July 1, 2020, were posted July 29 on the American Diabetes Association website.
The survey, conducted by the diabetes research company dQ&A in association with the ADA, revealed that Americans with diabetes are experiencing extreme financial pressures, leading to medication and supply rationing.
A high proportion of respondents had either lost income or are working in jobs that place them at risk for catching the novel coronavirus.
“These new numbers show the urgency needed to adopt measures to protect and assist the millions of people with diabetes who are suffering through this pandemic,” Tracey D. Brown, CEO of the ADA, said in a statement.
She called for states to extend health care coverage to people who have lost their jobs, for the eradication of insulin copays during the pandemic, and for increased COVID-19 testing capacity in high-risk communities.
“If these actions aren’t taken immediately, we will continue to see devastating impacts and outcomes for millions of vulnerable Americans,” Ms. Brown stressed.
COVID-19 has worsened financial pressures for people with diabetes
In the survey, 24% of respondents reported having used savings, loans, or stimulus check money to pay for diabetes care in the past 3 months. Among those who have lost income, half are using savings or stimulus money.
A quarter of respondents said they have been self-rationing supplies to cut costs.
Extrapolating to the entire U.S. population with diabetes, dQ&A estimated that roughly 650,000 are skipping insulin doses or taking less than prescribed, and 3 million are skipping blood glucose tests.
In June, the unemployment rate for people with diabetes was 18%, higher than the national rate of 12%.
Also higher is the proportion of those working prior to the pandemic who have since lost income: 33%, compared with 29% for the general population.
Among those who are self-employed, 7 in 10 of those with diabetes have lost some or all of their income.
Many with diabetes who are employed are vulnerable to exposure
Of those who remain employed, half said they can’t work from home.
Of those, 60% work in essential industries, with 22% in health care. A large majority, 90%, reported lack of social distancing at work and nearly a third work in places that don’t require masks.
“People with diabetes are helping to provide the services we all depend on during this pandemic, even as it puts their own well-being at risk,” the report said.
It concluded that “these numbers represent a conservative estimate of the pandemic’s impact. They are generated from an ongoing online study of the diabetes population amongst people who have opted in to participate.”

COVID-19–related skin changes: The hidden racism in documentation
Belatedly, the disproportionate impact of COVID-19 on patients of color is getting attention. By now, we’ve read the headlines. Black people in the United States make up about 13% of the population but account for almost three times (34%) as many deaths. This story repeats – in other countries and in other minority communities.
Early detection is critical both to initiate supportive care and to isolate affected individuals and limit spread. Skin manifestations of COVID-19, especially those that occur early in the disease (eg, vesicular eruptions) or have prognostic significance (livedo, retiform purpura, necrosis), are critical to this goal of early recognition.
In this context, a recent systematic literature review looked at all articles describing skin manifestations associated with COVID-19. The investigators identified 46 articles published between March and May 2020 which included a total of 130 clinical images.
The following findings from this study are striking:
- 92% of the published images of COVID-associated skin manifestations were in I-III.
- Only 6% of COVID skin lesions included in the articles were in patients with skin type IV.
- None showed COVID skin lesions in skin types V or VI.
- Only six of the articles reported race and ethnicity demographics. In those, 91% of the patients were White and 9% were Hispanic.
These results reveal a critical lack of representative clinical images of COVID-associated skin manifestations in patients of color. This deficiency is made all the more egregious given the fact that patients of color, including those who are Black, Latinx, and Native American, have been especially hard hit by the COVID-19 pandemic and suffer disproportionate disease-related morbidity and mortality.
As the study authors point out, skin manifestations in people of color often differ significantly from findings in White skin (for example, look at the figure depicting the rash typical of Kawasaki disease in a dark-skinned child compared with a light-skinned child). It is not a stretch to suggest that skin manifestations associated with COVID-19 may look very different in darker skin.
This isn’t a new phenomenon. Almost half of dermatologists feel that they’ve had insufficient exposure to skin disease in darker skin types. Skin of color remains underrepresented in medical journals.
Like other forms of passive, institutional racism, this deficiency will only be improved if dermatologists and dermatology publications actively seek out COVID-associated skin manifestations in patients of color and prioritize sharing these images. A medical student in the United Kingdom has gotten the ball rolling, compiling a handbook of clinical signs in darker skin types as part of a student-staff partnership at St. George’s Hospital and the University of London. At this time, Mind the Gap is looking for a publisher.
Dr. Lipper is an assistant clinical professor at the University of Vermont, Burlington, and a staff physician in the department of dermatology at Danbury (Conn.) Hospital. He has disclosed no relevant financial relationships.

Heart damage even after COVID-19 ‘recovery’ evokes specter of later heart failure
Evidence that the heart can take a major hit in patients hospitalized with COVID-19, especially those already with cardiovascular disease (CV) or its risk factors, has been sadly apparent from the pandemic’s earliest days.
Less clear from case studies and small series to date has been whether SARS-CoV-2 directly attacks the heart and whether acute cardiac effects of the illness may lead to some kind of lingering cardiomyopathy.
The field’s grasp of those issues advanced a bit in two new reports published July 27 in JAMA Cardiology that seem to validate concerns the virus can infect the myocardium, without necessarily causing myocarditis and the possibility that some “recovered” patients may be left with persisting myocardial injury and inflammation that potentially could later manifest as heart failure.
Persisting inflammation by cardiac magnetic resonance
A prospective cohort study with 100 patients recovered from a recent bout of the disease showed evidence of ventricular dysfunction, greater ventricular mass, and in 78% of the cohort, signs of myocardial inflammation by cardiac magnetic resonance (CMR) imaging. The CMR findings correlated with elevations in troponin T by high-sensitivity assay (hs-TnT).
Two-thirds of the cohort, whose acute COVID-19 severity had “ranged from asymptomatic to minor-to-moderate symptoms,” had recovered at home, whereas the remaining “severely unwell patients” had been hospitalized, wrote the authors, led by Valentina O. Püntmann, MD, PhD, University Hospital Frankfurt (Germany).
None of the patients had a history of heart failure or cardiomyopathy, although some had hypertension, diabetes, or evidence of coronary disease.
“Our findings demonstrate that participants with a relative paucity of preexisting cardiovascular condition and with mostly home-based recovery had frequent cardiac inflammatory involvement, which was similar to the hospitalized subgroup with regards to severity and extent,” the group noted.
“There is a considerable ongoing myocardial inflammation in the heart muscle weeks after recovery from COVID-19 illness. This finding is important because it may herald a considerable burden of heart failure in a few years down the line,” Dr. Püntmann said in an interview.
Early diagnosis would offer “a good chance that early treatment could reduce the relentless course of inflammatory damage or even halt it,” she said.
“The relatively clear onset of COVID-19 illness provides an opportunity, which we often do not have with other conditions, to take a proactive action and to look for heart involvement early, within a few weeks of recovery.”
The study’s CMR evidence of inflammation edema, scarring, and pericardial effusion are among “the major diagnostic criteria for inflammatory and viral myocarditis,” observed Biykem Bozkurt, MD, PhD, from Baylor College of Medicine, Houston, who wasn’t part of either new study.
The findings suggest – consistent with previous evidence – that some patients with recent COVID-19 may be left with ongoing myocardial inflammation, and this study further adds that it could potentially become subacute or even chronic and in some may not be totally reversible, she said in an interview. How long the effects are likely to persist “remains to be determined. We need longer-term outcomes data.”
Viral presence without myocarditis
The accompanying report featured a postmortem analysis of hearts from 39 patients with mostly severe COVID-19 that pointed to a significant SARS-CoV-2 presence and signs that the virus vigorously replicated in the myocardium.
But there was no evidence that the infection led to fulminant myocarditis. Rather, the virus had apparently infiltrated the heart by localizing in interstitial cells or in macrophages that took up in the myocardium without actually entering myocytes, concluded the report’s authors, led by Diana Lindner, PhD, from the University Heart and Vascular Centre, Hamburg (Germany).
The findings suggest “that the presence of SARS-CoV-2 in cardiac tissue does not necessarily cause an inflammatory reaction consistent with clinical myocarditis,” the group wrote.
Previously in the literature, in “cases in which myocardial inflammation was present, there was also evidence of clinical myocarditis, and therefore the current cases underlie a different pathophysiology,” they concluded.
No evidence of the virus was seen in 15 cases, about 61% of the group. In 16 of the remaining 24 hearts, the viral load exceeded 1,000 copies per mcg of RNA, a substantial presence. Those 16 showed increased expression of inflammatory cytokines but no inflammatory cell infiltrates or changes in leukocyte counts, the researchers noted.
“Findings of suggested viral replication in the cases with a very high viral load are showing that we need to do more studies to find out long-term consequences, which we do not know right now,” senior author Dirk Westermann, MD, also from the University Heart and Vascular Centre, Hamburg, said.
Implications for heart failure
The postmortem findings from Dr. Lindner and associates “provide intriguing evidence that COVID-19 is associated with at least some component of myocardial injury, perhaps as the result of direct viral infection of the heart,” wrote Clyde W. Yancy, MD, MSc, from Northwestern University, Chicago, and Gregg C. Fonarow, MD, from the University of California, Los Angeles, in an editorial accompanying both reports.
The CMR study from Dr. Püntmann and colleagues – on the backdrop of earlier COVID-19 observations – suggests the potential for “residual left ventricular dysfunction and ongoing inflammation” in the months following a COVID-19 diagnosis. Both developments may be “of sufficient concern to represent a nidus for new-onset heart failure and other cardiovascular complications,” contend Dr. Yancy and Dr. Fonarow.
“When added to the postmortem pathological findings from Lindner et al, we see the plot thickening and we are inclined to raise a new and very evident concern that cardiomyopathy and heart failure related to COVID-19 may potentially evolve as the natural history of this infection becomes clearer,” they wrote.
Some patients, having recovered from the acute illness, may be left with a chronic inflammatory state that probably puts them at increased risk for future heart failure, agreed Dr. Bozkurt when interviewed. “They could show further decline in cardiac function, and their recovery might take longer than with the usual viral illnesses that we see,” she said.
“There could also be a risk of sudden death. Inflammation sometimes gives rise to sudden death and ventricular arrhythmia, which I would be very worried about, especially if the myocardium is stressed,” Dr. Bozkurt said. “So competitive sports in those patients potentially could be risky.”
COVID-19 cohort vs. matched control subjects
The CMR study from Dr. Püntmann and colleagues prospectively entered 100 patients recently recovered from an acute bout of COVID-19, either at home or at a hospital, who were followed in a registry based at University Hospital Frankfurt. Their median age was 49 years; 47% were female. They were compared with 50 age- and sex-matched control patients and 50 apparently healthy volunteers matched for risk factors, the group noted.
On the same day as the CMR assessment, the recently recovered patients, compared with the healthy control subjects and risk-factor matched control subjects, respectively, showed (P ≤ .001 in each case):
- A reduced left ventricular (LV) ejection fraction: 56% vs. 60% and 61%.
- A higher LV end-diastolic volume index: 86 mL/m2 vs. 80 mL/m2 and 75 mL/m2.
- A greater LV mass index: 51 g/m2 vs. 47 g/m2 and 53 g/m2.
- A higher hs-TnT level: 5.6 pg/mL vs. 3.2 pg/mL and 3.9 pg/mL.
- A greater prevalence of hs-TnT levels 3 pg/mL or more: 71% vs. 11% and 31%.
At CMR, 78% of the recovered COVID-19 patients showed abnormalities that included raised myocardial native T1 and T2 mapping, which is suggestive of fibrosis and edema from inflammation, compared with the two control groups (P < .001 for all differences), “independent of preexisting conditions, severity and overall course of the acute illness, and the time from the original diagnosis,” the group wrote. Native T1 and T2 mapping correlated significantly with hs-TnT.
“We now have the diagnostic means to detect cardiac inflammation early, and we need make every effort to apply them in every day practice,”Dr. Püntmann said in the interview.
“Using cardiac MRI will allow us to raise our game against COVID-19 and proactively develop efficient cardioprotective treatments,” she said. “Until we have effective means of protecting from the infection, that is vaccination, we must act swiftly and within the means at hand.”
The analysis evokes several other ways patients with COVID-19 might be screened for significant myocardial involvement.
“Strategies could include checking troponins, not only at admission but maybe at discharge and perhaps even those individuals who are at home and are not necessarily requiring care,” Dr. Bozkurt said.
“Biomarker profiling and screening for ongoing inflammation probably are going to be important components of COVID-19, especially for those with subclinical risk and disease.”
Dr. Westermann proposed that troponin elevations at discharge “might be a good starting point” for selecting COVID-19 patients for functional testing or imaging to screen for cardiac sequelae. Performing such tests routinely now “would be overwhelming given the massive increase in patients we still see today.”
Dr. Püntmann had no disclosures; statements of potential conflict for the other authors are in the report. Dr. Bozkurt has previously disclosed receiving consultant fees or honoraria from Bayer Healthcare, Bristol-Myers Squibb, Lantheus Medical Imaging, and Respicardia; serving on a data safety monitoring board for LivaNova USA ; and having unspecified relationships with Abbott Laboratories. Dr. Lindner had no disclosures; Dr. Westermann reported receiving personal fees from AstraZeneca, Bayer, Novartis, and Medtronic.

Evidence that the heart can take a major hit in patients hospitalized with COVID-19, especially those already with cardiovascular disease (CV) or its risk factors, has been sadly apparent from the pandemic’s earliest days.
Less clear from case studies and small series to date has been whether SARS-CoV-2 directly attacks the heart and whether acute cardiac effects of the illness may lead to some kind of lingering cardiomyopathy.
The field’s grasp of those issues advanced a bit in two new reports published July 27 in JAMA Cardiology that seem to validate concerns the virus can infect the myocardium, without necessarily causing myocarditis and the possibility that some “recovered” patients may be left with persisting myocardial injury and inflammation that potentially could later manifest as heart failure.
Persisting inflammation by cardiac magnetic resonance
A prospective cohort study with 100 patients recovered from a recent bout of the disease showed evidence of ventricular dysfunction, greater ventricular mass, and in 78% of the cohort, signs of myocardial inflammation by cardiac magnetic resonance (CMR) imaging. The CMR findings correlated with elevations in troponin T by high-sensitivity assay (hs-TnT).
Two-thirds of the cohort, whose acute COVID-19 severity had “ranged from asymptomatic to minor-to-moderate symptoms,” had recovered at home, whereas the remaining “severely unwell patients” had been hospitalized, wrote the authors, led by Valentina O. Püntmann, MD, PhD, University Hospital Frankfurt (Germany).
None of the patients had a history of heart failure or cardiomyopathy, although some had hypertension, diabetes, or evidence of coronary disease.
“Our findings demonstrate that participants with a relative paucity of preexisting cardiovascular condition and with mostly home-based recovery had frequent cardiac inflammatory involvement, which was similar to the hospitalized subgroup with regards to severity and extent,” the group noted.
“There is a considerable ongoing myocardial inflammation in the heart muscle weeks after recovery from COVID-19 illness. This finding is important because it may herald a considerable burden of heart failure in a few years down the line,” Dr. Püntmann said in an interview.
Early diagnosis would offer “a good chance that early treatment could reduce the relentless course of inflammatory damage or even halt it,” she said.
“The relatively clear onset of COVID-19 illness provides an opportunity, which we often do not have with other conditions, to take a proactive action and to look for heart involvement early, within a few weeks of recovery.”
The study’s CMR evidence of inflammation edema, scarring, and pericardial effusion are among “the major diagnostic criteria for inflammatory and viral myocarditis,” observed Biykem Bozkurt, MD, PhD, from Baylor College of Medicine, Houston, who wasn’t part of either new study.
The findings suggest – consistent with previous evidence – that some patients with recent COVID-19 may be left with ongoing myocardial inflammation, and this study further adds that it could potentially become subacute or even chronic and in some may not be totally reversible, she said in an interview. How long the effects are likely to persist “remains to be determined. We need longer-term outcomes data.”

Patients with COPD plus sleep problems should be screened for mood disorders
A study has shown a strong link between sleeping disturbances and depression in patients with chronic obstructive pulmonary disease.
Adults with clinically stable COPD who reported sleep problems were significantly more likely to report depression or anxiety, poor self-efficacy, and poor health-related quality of life, compared with those not reporting sleep problems, according to the findings from a study of 245 patients.
Sleep problems are common in patients with COPD and have been associated with poor COPD-related outcomes, wrote Sang Hee Lee, MD, of Wonkwang University Sanbon Hospital, Gunpo-si, South Korea, and colleagues.
“However, there is a lack of research on factors associated with sleep disturbance in patients with COPD,” they wrote.
In a prospective, multicenter, cross-sectional study published in the Clinical Respiratory Journal, the researchers enrolled 245 adults with COPD who completed the COPD and Asthma Impact Scale (CASIS) to determine sleep impairment. The CASIS was developed to measure sleep-related problems associated with respiratory disease, and scored on a scale of 1-100, with higher scores indicating greater sleep impairment. The average CASIS score was 40.9. The average age of the patients was 67 years, and 92% were men.
Patients’ health-related quality of life, anxiety/depression, and self-efficacy were assessed using the St. George’s Respiratory Questionnaire (SGRQ), the 36-item Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale (HADS), and the COPD Self-Efficacy Scale (CSES). The average scores on these measures were 36.0 for the SGRQ; 48.1 and 50.6, respectively, for the physical and mental components of the SF-36; 3.8 and 6.4, respectively, for the HADS-A and HADS-D measures of anxiety and depression; and 3.3 on the CSES.
Worse sleep in these patients was associated with worse scores on measures of mood. In a multivariate analysis, higher scores on all four measures of health-related quality of life were significantly associated with higher CASIS scores (P = .006 for SGRQ; P = .037 for SF-36, P < .001 for HADS, and P = .010 for CSES).
Although the CASIS did not allow for measurement of symptom severity and did not include many items related to breathing problems, the test “shows good internal consistency, test-retest reproducibility, and construct validity according to previous studies,” the researchers wrote. “The CASIS may be a good tool for evaluating sleep disturbances in COPD patients, and further study is needed,” they added.
The study findings were limited by several factors including the cross-sectional study design, lack of data on obstructive sleep apnea, and lack of information on specific treatments such as at-home oxygen use or high-dose steroid use, the researchers noted. However, the results were strengthened by the use of a disease-specific sleep measure, and the study is the first known to include self-efficacy in relation to sleep quality in COPD patients, they reported.
The results highlight the association between depression, poor quality of life, and self-efficacy in relation to poor sleep, and suggest that “Sleep quality could be improved by enhancing HRQL and self-efficacy,” the researchers said. “Screening for mood disorder in patients with COPD is also needed,” they concluded.
The study was supported by the Basic Science Research Program of the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology. The researchers had no financial conflicts to disclose.

Patients’ health-related quality of life, anxiety/depression, and self-efficacy were assessed using the St. George’s Respiratory Questionnaire (SGRQ), the 36-item Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale (HADS), and the COPD Self-Efficacy Scale (CSES). The average scores on these measures were 36.0 for the SGRQ; 48.1 and 50.6, respectively, for the physical and mental components of the SF-36; 3.8 and 6.4, respectively, for the HADS-A and HADS-D measures of anxiety and depression; and 3.3 on the CSES.
Worse sleep in these patients was associated with worse scores on measures of mood. In a multivariate analysis, higher scores on all four measures of health-related quality of life were significantly associated with higher CASIS scores (P = .006 for SGRQ; P = .037 for SF-36, P < .001 for HADS, and P = .010 for CSES).
Although the CASIS did not allow for measurement of symptom severity and did not include many items related to breathing problems, the test “shows good internal consistency, test-retest reproducibility, and construct validity according to previous studies,” the researchers wrote. “The CASIS may be a good tool for evaluating sleep disturbances in COPD patients, and further study is needed,” they added.
The study findings were limited by several factors including the cross-sectional study design, lack of data on obstructive sleep apnea, and lack of information on specific treatments such as at-home oxygen use or high-dose steroid use, the researchers noted. However, the results were strengthened by the use of a disease-specific sleep measure, and the study is the first known to include self-efficacy in relation to sleep quality in COPD patients, they reported.
The results highlight the association between depression, poor quality of life, and self-efficacy in relation to poor sleep, and suggest that “Sleep quality could be improved by enhancing HRQL and self-efficacy,” the researchers said. “Screening for mood disorder in patients with COPD is also needed,” they concluded.
The study was supported by the Basic Science Research Program of the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology. The researchers had no financial conflicts to disclose.

More data needed to better understand COVID-19 skin manifestations
Qing Zhao, MD, Xiaokai Fang, MD, and their colleagues at the Shandong Provincial Hospital for Skin Diseases & Shandong Provincial Institute of Dermatology and Venereology, in Jinan, China, reported the results of a literature review of 44 articles published through May 2020 that included 507 patients with cutaneous manifestations of COVID-19. The review was published in the Journal of The European Academy of Dermatology and Venereology.
Nearly all of the patients (96%) were from Europe, and more than half were women (60%), with an average age of 49 years. Most patients had multiple skin symptoms, with the most common being erythema (44%), chilblain-like lesions (20%), urticaria-like lesions (16%), vesicular manifestations (13%), livedo/necrosis (6%), and petechiae (almost 2%). The authors described erythema as being present in specific sites, such as the trunk, extremities, flexural regions, face, and mucous membranes. Slightly less than half of all patients had significant pruritus.
Data on systemic COVID-19 symptoms were available for 431 patients and included fever in about two-thirds of patients and cough in almost 70%, with dyspnea in almost half of patients. Almost 60% had fatigue, and almost 60% had asthenia. Information about the onset of skin symptoms was available in 88 patients; of these patients, lesions were seen an average of almost 10 days after systemic symptoms appeared and, in almost 15%, were the first symptoms noted.
Histopathologic exams were done for only 23 patients and, in all cases, showed “inflammatory features without specific pathological changes, such as lymphocyte infiltration.” In one study, reverse transcription polymerase chain reaction testing of skin biopsy specimens tested negative for SARS-CoV-2.
Expression of ACE2, the receptor of SARS-CoV-2, in the skin was evaluated in six of the studies. “Higher ACE2 expression was identified in keratinocytes, mainly in differentiating keratinocytes and basal cells compared to the other cells of skin tissues,” the authors wrote. These results were confirmed with immunohistochemistry, which, they said, found “ACE2-positive keratinocytes in the stratum basal, the stratum spinosum, and the stratum granulosum of epiderma.” They added that this provides evidence “for percutaneous infection or the entry of virus into patients through skin tissues,” but cautioned that more research is needed.
The authors acknowledged that there are still many unanswered questions about COVID-19, and that more clinical data and research are needed, to improve the understanding of the cutaneous manifestations associated with COVID-19.
In an interview, Alisa N. Femia, MD, director of inpatient dermatology in the department of dermatology at New York University, said that the cutaneous signs described in the review align well with what she has seen in patients with COVID-19.
At this point, it is unclear whether cutaneous manifestations of COVID-19 are a result of SARS-CoV-2 invading the skin or an immune response related to SARS-CoV-2, noted Dr. Femia, who was not involved in the research. One method of entry could be through transmitting virus present on the skin to another part of the body where infection is more likely.
While it is possible COVID-19 could be contracted through the skin, she noted, it is much more likely an individual would be infected by SARS-CoV-2 through more traditionally understood means of transmission, such as through respiratory droplets in person-to-person contact. “I think we are far away from drawing that conclusion, that one could touch a surface or a person who has COVID and contract it through their skin,” Dr. Femia said. “The skin has a lot of other ways to protect against that from occurring,” she added.
“SAR-CoV-2 obviously enters through the ACE2 receptor, which is fairly ubiquitous, and it has been seen in keratinocytes,” she said. “But the skin is one of our biggest barriers ... and further, studies to date have shown that that receptor is expressed in relatively low levels of the keratinocytes.”
Pathogenesis of different cutaneous manifestations may be different, Dr. Femia said. For example, urticaria and morbilliform eruption were described by the authors of the review as more benign eruptions, but pathogenesis may differ from that of so-called COVID toes and from the pathogenesis of purpura and ulcerations seen in patients with more severe disease, she noted. It is plausible, she added, that purpura and ulcerations may be a “direct invasion of SARS-CoV-2 into endothelial cells,” which creates secondary processes “that ultimately destroy the skin.”
Urticaria and morbilliform eruptions, on the other hand, “are more simply that the immune system is recognizing COVID, and in doing so, is also recognizing some antigens in the skin and creating a hypersensitive response to the skin” and has “nothing to do with the SARS-CoV-2 virus actually being in that location,” she said.
It is important to differentiate between patients who have skin manifestations attributed to COVID-19 and those with manifestations independent of COVID-19, which is difficult, Dr. Femia noted. A patient with COVID-19 and a cutaneous manifestation may be having a reaction to a medication. “It’s important to have a critical eye and to remember that, when we see these manifestations, we should always be investigating whether there was an alternative cause so that we can better learn what exactly we should be attributing to this infection,” she said
Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, Washington, said the authors of the review had presented interesting work, but made some “assumptions that need to be proven.” Dr. Friedman also was not involved in the research, but agreed in an interview with the assessment that it is unlikely SARS-CoV-2 would penetrate the skin. While some viruses – such as the poxvirus that causes molluscum contagiosum and the herpes simplex virus – invade keratinocytes specifically, there is a particular clinical phenotype that results that is associated with changes in the epidermis. However, “the skin manifestations of COVID-19 do not fit with direct skin invasion, [but] rather the immune response to systemic disease,” he said.
“[I]n terms of systemic invasion through the skin, it is possible, but this study certainly doesn’t show that. The presence/expression of ACE2 in the epidermis doesn’t translate to route of infection,” Dr. Friedman said..
The study received financial support from Shandong First Medical University, the Innovation Project of Shandong Academy of Medical Sciences and the Shandong Province Taishan Scholar Project. The authors report no relevant financial disclosures. Dr. Femia and Dr. Friedman had no relevant financial disclosures.

Are you SARS-CoV-2 vaccine hesitant?
When the pandemic was just emerging from its infancy and we were just beginning to think about social distancing, I was sitting around enjoying an adult beverage and some gluten free (not my choice) snacks with some friends. A retired nurse who had just celebrated her 80th birthday said, “I can’t wait until they’ve developed a vaccine.” A former electrical engineer sitting just short of 2 meters to her left responded, “Don’t save me a place near the front of the line for something that is being developed in a program called Warp Speed.”
How do you feel about the potential SARS-CoV-2 vaccine? Are you going to roll up your sleeve as soon as the vaccine becomes available in your community? What are you going to suggest to your patients, your children? I suspect many of you will answer, “It depends.”
Will it make any difference to you which biochemical-immune-bending strategy is being used to make the vaccine? All of them will probably be the result of a clever sounding but novel technique, all of them with a track record that is measured in months and not years. Will you be swayed by how large the trials were? Or how long the follow-up lasted? How effective must the vaccine be to convince you that it is worth receiving or recommending? Do you have the tools and experience to make a decision like that? I know I don’t. And should you and I even be put in a position to make that decision?
In the past, you and I may have relied on the Centers for Disease Control and Prevention for advice. But given the somewhat murky and stormy relationship between the CDC and the president, the vaccine recommendation may be issued by the White House and not the CDC.
For those of us who were practicing medicine during the Swine Flu fiasco of 1976, the pace and the politics surrounding the development of a SARS-CoV-2 vaccine has a discomforting déjà vu quality about it. The fact that like this year 1976 was an election year that infused the development process with a sense of urgency above and beyond any of the concerns about the pandemic that never happened. Although causality was never proven, there was a surge in Guillain-Barré syndrome cases that had been linked temporally to the vaccine.
Of course, our pandemic is real, and it would be imprudent to wait a year or more to watch for long-term vaccine sequelae. However, I am more than a little concerned that fast tracking the development process may result in unfortunate consequences in the short term that could have been avoided with a more measured approach to trialing the vaccines.
The sad reality is that as a nation we tend to be impatient. We are drawn to quick fixes that come in a vial or a capsule. We are learning that simple measures like mask wearing and social distancing can make a difference in slowing the spread of the virus. It would be tragic to rush a vaccine into production that at best turns out to simply be an expensive alternative to the measures that we know work or at worst injures more of us than it saves.

COVID-19 bits and pieces
It turns out that a pandemic, at least this COVID-19 version, can be a challenge for folks like me who are seldom at a loss for words. The pandemic has so overwhelmed every corner of our lives that it is hard to think of another topic on which to pontificate and still not tromp on someone’s political toes. One can always write about the pandemic itself, and I’ve tried that, but as the curtain is gradually being pulled back on this crafty little germ one runs the risk of making an observation today that will be disproved in a week or 2. However, I can’t suppress my urge to write, and so I have decided to share a few brief random observations. Of course they are related to the pandemic. And of course I realize that there is a better than fifty percent chance that they will be proved wrong by the time you read my next Letters from Maine.
Under the radar
Two of the many mysteries about SARS-CoV-2 involve young children who as a group appear to be less easily infected than adults and even when infected seem to be less likely to spread the disease to other people, particularly adults. One explanation posited by some researchers in France is that young children are less likely to have symptoms such as cough and are less powerful speakers and so might be less likely to spew out a significant number of infected aerosolized droplets (“How to Reopen Schools: What Science and Other Countries Teach Us.” By Pam Belluck, Apoorva Mandavill, and Benedict Carey. New York Times, July 11, 2020). While there are probably several factors to explain this observation, one may be that young children are short, seldom taller than an adult waistline. I suspect the majority of aerosols they emit fall and inactivate harmlessly to the floor several feet below an adult’s nose and mouth. Regardless of the explanation, it appears to be good news for the opening of schools, at least for the early grades.
Forget the deep cleaning
There has been a glut of news stories about reopening schools, and many of these stories are accompanied by images of school custodians with buckets, mops, spray bottles, and sponges scouring desks and walls. The most recent image in our local newspaper was of someone scrubbing the underside of a desk. I know it’s taking the World Health Organization an unconscionable period of time to acknowledge that SARS-CoV-2 is airborne, but the rest of us should have gotten the message long ago and been directing our attention to air handling and ventilation. The urge to scrub and deep clean is a hard habit to break, but this nasty bug is not like influenza or a flesh eating bacteria in which deep cleaning might help. A better image to attach to a story on school reopening would be one of a custodian with a screwdriver struggling to pry open a classroom window that had been painted shut a decade ago.
Managing the inevitable
Middlebury College in Vermont and Bowdoin College here in Brunswick, Maine, are similar in many respects because they are small and situated in relatively isolated small New England towns with good track records for pandemic management. Middlebury has elected to invite all its 2,750 students back to campus, whereas Bowdoin has decided to allow only incoming first years and transfer students (for a total of about 600) to return.

It turns out that a pandemic, at least this COVID-19 version, can be a challenge for folks like me who are seldom at a loss for words. The pandemic has so overwhelmed every corner of our lives that it is hard to think of another topic on which to pontificate and still not tromp on someone’s political toes. One can always write about the pandemic itself, and I’ve tried that, but as the curtain is gradually being pulled back on this crafty little germ one runs the risk of making an observation today that will be disproved in a week or 2. However, I can’t suppress my urge to write, and so I have decided to share a few brief random observations. Of course they are related to the pandemic. And of course I realize that there is a better than fifty percent chance that they will be proved wrong by the time you read my next Letters from Maine.
Under the radar
Two of the many mysteries about SARS-CoV-2 involve young children who as a group appear to be less easily infected than adults and even when infected seem to be less likely to spread the disease to other people, particularly adults. One explanation posited by some researchers in France is that young children are less likely to have symptoms such as cough and are less powerful speakers and so might be less likely to spew out a significant number of infected aerosolized droplets (“How to Reopen Schools: What Science and Other Countries Teach Us.” By Pam Belluck, Apoorva Mandavill, and Benedict Carey. New York Times, July 11, 2020). While there are probably several factors to explain this observation, one may be that young children are short, seldom taller than an adult waistline. I suspect the majority of aerosols they emit fall and inactivate harmlessly to the floor several feet below an adult’s nose and mouth. Regardless of the explanation, it appears to be good news for the opening of schools, at least for the early grades.
Forget the deep cleaning
There has been a glut of news stories about reopening schools, and many of these stories are accompanied by images of school custodians with buckets, mops, spray bottles, and sponges scouring desks and walls. The most recent image in our local newspaper was of someone scrubbing the underside of a desk. I know it’s taking the World Health Organization an unconscionable period of time to acknowledge that SARS-CoV-2 is airborne, but the rest of us should have gotten the message long ago and been directing our attention to air handling and ventilation. The urge to scrub and deep clean is a hard habit to break, but this nasty bug is not like influenza or a flesh eating bacteria in which deep cleaning might help. A better image to attach to a story on school reopening would be one of a custodian with a screwdriver struggling to pry open a classroom window that had been painted shut a decade ago.
Managing the inevitable
Middlebury College in Vermont and Bowdoin College here in Brunswick, Maine, are similar in many respects because they are small and situated in relatively isolated small New England towns with good track records for pandemic management. Middlebury has elected to invite all its 2,750 students back to campus, whereas Bowdoin has decided to allow only incoming first years and transfer students (for a total of about 600) to return. Both schools will institute similar testing and social distancing protocols and restrict students from access to their respective towns (“A Tale of 2 Colleges.” By Bill Burger.

Higher death rate seen in cancer patients with nosocomial COVID-19
, according to researchers.
In an observational study of patients with COVID-19 and cancer, 19% of patients had COVID-19 acquired during a non-COVID-related hospital stay, and 81% had community-acquired COVID-19.
At a median follow-up of 23 days, the overall mortality rate was 28%. However, the all-cause mortality rate in patients with nosocomial COVID-19 was more than double that of patients with community-acquired COVID-19, at 47% and 23%, respectively.
Arielle Elkrief, MD, of the University of Montreal, reported these results during the AACR virtual meeting: COVID-19 and Cancer.
“This is the first report that describes a high rate of hospital-acquired COVID-19 in patients with cancer, at a rate of 19%,” Dr. Elkrief said. “This was associated with high mortality in both univariate and multivariate analyses.”
The study included 250 adults and 3 children with COVID-19 and cancer who were identified between March 3 and May 23, 2020. They ranged in age from 4 to 95 years, but the median age was 73 years.
All patients had either laboratory-confirmed (95%) or presumed COVID-19 (5%) and invasive cancer. The most common cancer types were similar to those seen in the general population. Lung and breast cancer were the most common, followed by lymphoma, prostate cancer, and colorectal cancer. Most patients were on active anticancer therapy, most often chemotherapy.
Most patients (n = 236) were residents of Quebec, but 17 patients were residents of British Columbia.
“It is important to note that Quebec was one of the most heavily affected areas in North America at the time of the study,” Dr. Elkrief said.
Outcomes by group
There were 206 patients (81%) who had community-acquired COVID-19 and 47 (19%) who had nosocomial COVID-19. The two groups were similar with respect to sex, performance status, and cancer stage. A small trend toward more patients on active therapy was seen in the nosocomial group, but the difference did not reach statistical significance.
The median overall survival was 27 days in the nosocomial group and 71 days in the community-acquired group (hazard ratio, 2.2; P = .002).
A multivariate analysis showed that nosocomial infection was “strongly and independently associated with death,” Dr. Elkrief said. “Other risk factors for poor prognosis included age, poor [performance] status, and advanced stage of cancer.”
There were no significant differences between the hospital-acquired and community-acquired groups for other outcomes, including oxygen requirements (43% and 47%, respectively), ICU admission (13% and 11%), need for mechanical ventilation (6% and 5%), or length of stay (median, 9.5 days and 8.5 days).
The low rate of ICU admission, considering the mortality rate of 28%, “could reflect that patients with cancer are less likely to be admitted to the ICU,” Dr. Elkrief noted.
Applying the findings to practice
The findings reinforce the importance of adherence to stringent infection control guidelines to protect vulnerable patients, such as those with cancer, Dr. Elkrief said.
In ambulatory settings, this means decreasing in-person visits through increased use of teleconsultations, and for those who need to be seen in person, screening for symptoms or use of polymerase chain reaction testing should be used when resources are available, she said.
“Similar principles apply to chemotherapy treatment units,” Dr. Elkrief said. She added that staff must avoid cross-contamination between COVID and COVID-free zones, and that “dedicated personnel and equipment should be maintained and separate between these two zones.
“Adequate protective personal equipment and strict hand hygiene protocols are also of utmost importance,” Dr. Elkrief said. “The threat of COVID-19 is not behind us, and so we continue to enforce these strategies to protect our patients.”
Session moderator Gypsyamber D’Souza, PhD, an infectious disease epidemiologist at Johns Hopkins University in Baltimore, raised the question of whether the high nosocomial infection and death rate in this study was related to patients having more severe disease because of underlying comorbidities.
Dr. Elkrief explained that the overall mortality rate was indeed higher than the 13% reported in other studies, and it may reflect an overrepresentation of hospitalized or more severely ill patients in the cohort.
However, the investigators made every effort to include all patients with both cancer and COVID-19 by using systematic screening of inpatient and outpatients lists and registries.
Further, the multivariate analysis included both inpatients and outpatients and adjusted for known negative prognostic factors for COVID-19 outcomes. These included increasing age, poor performance status, and different comorbidities.
The finding that nosocomial infection was an independent predictor of death “pushed us to look at nosocomial infection as a new independent risk factor,” Dr. Elkrief said.
Dr. Elkrief reported grant support from AstraZeneca. Dr. D’Souza did not report any disclosures.

Low vitamin D linked to increased COVID-19 risk
Low plasma vitamin D levels emerged as an independent risk factor for COVID-19 infection and hospitalization in a large, population-based study.
Participants positive for COVID-19 were 50% more likely to have low vs normal 25(OH)D levels in a multivariate analysis that controlled for other confounders, for example.
The take home message for physicians is to “test patients’ vitamin D levels and keep them optimal for the overall health – as well as for a better immunoresponse to COVID-19,” senior author Milana Frenkel-Morgenstern, PhD, head of the Cancer Genomics and BioComputing of Complex Diseases Lab at Bar-Ilan University in Ramat Gan, Israel, said in an interview.
The study was published online July 23 in The FEBS Journal.
Previous and ongoing studies are evaluating a potential role for vitamin D to prevent or minimize the severity of SARS-CoV-2 infection, building on years of research addressing vitamin D for other viral respiratory infections. The evidence to date regarding COVID-19, primarily observational studies, has yielded mixed results.
Multiple experts weighed in on the controversy in a previous report. Many point out the limitations of observational data, particularly when it comes to ruling out other factors that could affect the severity of COVID-19 infection. In addition, in a video report, JoAnn E. Manson, MD, DrPH, of Harvard Medical School in Boston, cited an observational study from three South Asian hospitals that found more severe COVID-19 patients had lower vitamin D levels, as well as other “compelling evidence” suggesting an association.
Dr. Frenkel-Morgenstern and colleagues studied data for 7,807 people, of whom 10.1% were COVID-19 positive. They assessed electronic health records for demographics, potential confounders, and outcomes between February 1 and April 30.
Participants positive for COVID-19 tended to be younger and were more likely to be men and live in a lower socioeconomic area, compared with the participants who were negative for COVID-19, in a univariate analysis.
Key findings
A higher proportion of COVID-19–positive patients had low plasma 25(OH)D concentrations, about 90% versus 85% of participants who were negative for COVID-19. The difference was statistically significant (P < .001). Furthermore, the increased likelihood for low vitamin D levels among those positive for COVID-19 held in a multivariate analysis that controlled for demographics and psychiatric and somatic disorders (adjusted odds ratio, 1.50). The difference remained statistically significant (P < .001).
The study also was noteworthy for what it did not find among participants with COVID-19. For example, the prevalence of dementia, cardiovascular disease, chronic lung disorders, and hypertension were significantly higher among the COVID-19 negative participants.
“Severe social contacts restrictions that were imposed on all the population and were even more emphasized in this highly vulnerable population” could explain these findings, the researchers noted.
“We assume that following the Israeli Ministry of Health instructions, patients with chronic medical conditions significantly reduced their social contacts” and thereby reduced their infection risk.
In contrast to previous reports, obesity was not a significant factor associated with increased likelihood for COVID-19 infection or hospitalization in the current study.
The researchers also linked low plasma 25(OH)D level to an increased likelihood of hospitalization for COVID-19 infection (crude OR, 2.09; P < .05).
After controlling for demographics and chronic disorders, the aOR decreased to 1.95 (P = .061) in a multivariate analysis. The only factor that remained statistically significant for hospitalization was age over 50 years (aOR, 2.71; P < .001).
Implications and future plans
The large number of participants and the “real world,” population-based design are strengths of the study. Considering potential confounders is another strength, the researchers noted. The retrospective database design was a limitation.
Going forward, Dr. Frenkel-Morgenstern and colleagues will “try to decipher the potential role of vitamin D in prevention and/or treatment of COVID-19” through three additional studies, she said. Also, they would like to conduct a meta-analysis to combine data from different countries to further explore the potential role of vitamin D in COVID-19.
“A compelling case”
“This is a strong study – large, adjusted for confounders, consistent with the biology and other clinical studies of vitamin D, infections, and COVID-19,” Wayne Jonas, MD, a practicing family physician and executive director of Samueli Integrative Health Programs, said in an interview.
Because the research was retrospective and observational, a causative link between vitamin D levels and COVID-19 risk cannot be interpreted from the findings. “That would need a prospective, randomized study,” said Dr. Jonas, who was not involved with the current study.
However, “the study makes a compelling case for possibly screening vitamin D levels for judging risk of COVID infection and hospitalization,” Dr. Jonas said, “and the compelling need for a large, randomized vitamin D supplement study to see if it can help prevent infection.”
“Given that vitamin D is largely safe, such a study could be done quickly and on healthy people with minimal risk for harm,” he added.
More confounders likely?
“I think the study is of interest,” Naveed Sattar, PhD, professor of metabolic medicine at the University of Glasgow, who also was not affiliated with the research, said in an interview.
“Whilst the authors adjusted for some confounders, there is a strong potential for residual confounding,” said Dr. Sattar, a coauthor of a UK Biobank study that did not find an association between vitamin D stages and COVID-19 infection in multivariate models.
For example, Dr. Sattar said, “Robust adjustment for social class is important since both Vitamin D levels and COVID-19 severity are both strongly associated with social class.” Further, it remains unknown when and what time of year the vitamin D concentrations were measured in the current study.
“In the end, only a robust randomized trial can tell us whether vitamin D supplementation helps lessen COVID-19 severity,” Dr. Sattar added. “I am not hopeful we will find this is the case – but I am glad some such trials are [ongoing].”
Dr. Frenkel-Morgenstern received a COVID-19 Data Sciences Institute grant to support this work. Dr. Frenkel-Morgenstern, Dr. Jonas, and Dr. Sattar have disclosed no relevant financial relationships.

Also, they would like to conduct a meta-analysis to combine data from different countries to further explore the potential role of vitamin D in COVID-19.
“A compelling case”
“This is a strong study – large, adjusted for confounders, consistent with the biology and other clinical studies of vitamin D, infections, and COVID-19,” Wayne Jonas, MD, a practicing family physician and executive director of Samueli Integrative Health Programs, said in an interview.
Because the research was retrospective and observational, a causative link between vitamin D levels and COVID-19 risk cannot be interpreted from the findings. “That would need a prospective, randomized study,” said Dr. Jonas, who was not involved with the current study.
However, “the study makes a compelling case for possibly screening vitamin D levels for judging risk of COVID infection and hospitalization,” Dr. Jonas said, “and the compelling need for a large, randomized vitamin D supplement study to see if it can help prevent infection.”
“Given that vitamin D is largely safe, such a study could be done quickly and on healthy people with minimal risk for harm,” he added.
More confounders likely?
“I think the study is of interest,” Naveed Sattar, PhD, professor of metabolic medicine at the University of Glasgow, who also was not affiliated with the research, said in an interview.
“Whilst the authors adjusted for some confounders, there is a strong potential for residual confounding,” said Dr. Sattar, a coauthor of a UK Biobank study that did not find an association between vitamin D stages and COVID-19 infection in multivariate models.
For example, Dr. Sattar said, “Robust adjustment for social class is important since both Vitamin D levels and COVID-19 severity are both strongly associated with social class.” Further, it remains unknown when and what time of year the vitamin D concentrations were measured in the current study.
“In the end, only a robust randomized trial can tell us whether vitamin D supplementation helps lessen COVID-19 severity,” Dr. Sattar added. “I am not hopeful we will find this is the case – but I am glad some such trials are [ongoing].”

Low plasma vitamin D levels emerged as an independent risk factor for COVID-19 infection and hospitalization in a large, population-based study.
Participants positive for COVID-19 were 50% more likely to have low vs normal 25(OH)D levels in a multivariate analysis that controlled for other confounders, for example.
The take home message for physicians is to “test patients’ vitamin D levels and keep them optimal for the overall health – as well as for a better immunoresponse to COVID-19,” senior author Milana Frenkel-Morgenstern, PhD, head of the Cancer Genomics and BioComputing of Complex Diseases Lab at Bar-Ilan University in Ramat Gan, Israel, said in an interview.
The study was published online July 23 in The FEBS Journal.
Previous and ongoing studies are evaluating a potential role for vitamin D to prevent or minimize the severity of SARS-CoV-2 infection, building on years of research addressing vitamin D for other viral respiratory infections. The evidence to date regarding COVID-19, primarily observational studies, has yielded mixed results.
Multiple experts weighed in on the controversy in a previous report. Many point out the limitations of observational data, particularly when it comes to ruling out other factors that could affect the severity of COVID-19 infection. In addition, in a video report, JoAnn E. Manson, MD, DrPH, of Harvard Medical School in Boston, cited an observational study from three South Asian hospitals that found more severe COVID-19 patients had lower vitamin D levels, as well as other “compelling evidence” suggesting an association.
Dr. Frenkel-Morgenstern and colleagues studied data for 7,807 people, of whom 10.1% were COVID-19 positive. They assessed electronic health records for demographics, potential confounders, and outcomes between February 1 and April 30.
Participants positive for COVID-19 tended to be younger and were more likely to be men and live in a lower socioeconomic area, compared with the participants who were negative for COVID-19, in a univariate analysis.
Key findings
A higher proportion of COVID-19–positive patients had low plasma 25(OH)D concentrations, about 90% versus 85% of participants who were negative for COVID-19. The difference was statistically significant (P < .001). Furthermore, the increased likelihood for low vitamin D levels among those positive for COVID-19 held in a multivariate analysis that controlled for demographics and psychiatric and somatic disorders (adjusted odds ratio, 1.50). The difference remained statistically significant (P < .001).
The study also was noteworthy for what it did not find among participants with COVID-19. For example, the prevalence of dementia, cardiovascular disease, chronic lung disorders, and hypertension were significantly higher among the COVID-19 negative participants.
“Severe social contacts restrictions that were imposed on all the population and were even more emphasized in this highly vulnerable population” could explain these findings, the researchers noted.
“We assume that following the Israeli Ministry of Health instructions, patients with chronic medical conditions significantly reduced their social contacts” and thereby reduced their infection risk.
In contrast to previous reports, obesity was not a significant factor associated with increased likelihood for COVID-19 infection or hospitalization in the current study.
The researchers also linked low plasma 25(OH)D level to an increased likelihood of hospitalization for COVID-19 infection (crude OR, 2.09; P < .05).
After controlling for demographics and chronic disorders, the aOR decreased to 1.95 (P = .061) in a multivariate analysis. The only factor that remained statistically significant for hospitalization was age over 50 years (aOR, 2.71; P < .001).
Implications and future plans
The large number of participants and the “real world,” population-based design are strengths of the study. Considering potential confounders is another strength, the researchers noted. The retrospective database design was a limitation.
