Clinical

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/m^2.
• A greater LV mass index: 51 g/m² vs. 47 g/m² and 53 g/m^2.
• 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. Dr. Yancy is a deputy editor and Dr. Fonarow a section editor for JAMA Cardiology. Dr. Yancy had no other disclosures. Dr. Fonarow reported receiving personal fees from Abbott Laboratories, Amgen, AstraZeneca, Bayer, CHF Solutions, Edwards Lifesciences, Janssen, Medtronic, Merck, and Novartis.

An erythematous rash was the most common cutaneous manifestation in patients with COVID-19, followed by chilblain-like lesions and urticaria-like lesions in a systematic review of mostly European studies.

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.

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.

An erythematous rash was the most common cutaneous manifestation in patients with COVID-19, followed by chilblain-like lesions and urticaria-like lesions in a systematic review of mostly European studies.

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.

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.

Hospitalized cancer patients have a high risk of nosocomial COVID-19 that is associated with increased mortality, so these patients should be treated in COVID-free zones, 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 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.

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.

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.

Sleep difficulties during the COVID-19 crisis may be exacerbated by media overexposure and other factors causing fear and stress, according to findings from a large survey of French individuals.

“Physicians usually recommend coping with sleep disorders by exercising, going outside, avoiding screen time, and having a regular schedule – all recommendations difficult to apply during lockdown. Being forced to stay home and the ensuing boredom and loneliness may have led to increased [media exposure], especially among disadvantaged people and overexposure to media COVID-19 content may have contributed to fright and emotional distress,” Damien Leger of the Centre du Sommeil et de la Vigilance, Hôtel Dieu APHP, Université de Paris, and his colleagues wrote in the journal Sleep.

The investigators analyzed data from survey respondents about their sleep problems since the COVID-19 lockdown and other topics such as employment, daily activities, and sleep medications. The survey was part of a large research project, COCONEL, that has been developed to study the French population on a variety of behaviors and comprises 750,000 permanent panelists who respond to surveys. The survey was sent to random sample of panelists with no topic label to avoid selection bias. Of the 25,800 surveys sent, 1,005 responses were recorded.

Respondents were classified as having severe sleep problems if they reported that their daytime activities were affected or if their sleeping medications had increased since the lockdown. While 73% of respondents reported poor sleep in the 8 previous days, 25% reported severe sleep problems, and 54% reported that their sleep problems had worsened during the COVID-19 lockdown.

A media exposure score was created with a Likert scale (strongly agree, agree, disagree, strongly disagree) about media exposures of different types. The investigators also queried respondents about the degree to which they found media coverage of the pandemic provoked a fear response. Overall, 68% of respondents agreed that media images and stories about COVD-19 were frightening.

The researchers found a strong association between severe sleeping problems and a high media exposure score (risk ratio, 1.49; 95% confidence interval, 1.10-2.01; P < .05).

In addition, trepidation and fear from media exposure to COVID-19 news were also associated with severe sleep problems (RR, 1.27; 95% CI, 0.92-1.75; P < .05). “Suffering from sleep problems may have increased media use at night, and thus increased stress and/or psychological distress and reinforced sleeping problems,” the investigators wrote.

Not surprisingly, respondents with financial difficulties due to the pandemic also reported severe sleeping difficulties (RR, 1.99; 95% CI, 1.49-2.65; P < .05).

For individuals who have been treated for sleep problems, the COVID-19 pandemic may ratchet up their sleep challenges. The strongest association with severe sleep problems was found in those respondents who were already taking sleeping medications before the pandemic (RR, 2.72; 95% CI, 2.04-3.61; P < .05).

The COCONEL survey has been funded by the French and National Agency for Research, the Fondation de France, and the National Research Institute for Sustainable Development.

Parents who refuse one indicated neonatal preventive therapy often refuse others even when the reasons are different, according to an update at the virtual Pediatric Hospital Medicine virtual. This finding indicates the value of preparing policies and strategies to guide parents to appropriate medical decisions in advance.

“Elimination of nonmedical exceptions to vaccinations and intramuscular vitamin K made it into two of the AAP [American Academy of Pediatrics] top 10 public health resolutions, most likely because refusal rates are going up,” reported Ha N. Nguyen, MD, of the division of pediatric hospital medicine at Stanford (Calif.) University.

Importantly, state laws differ. For example, erythromycin ointment is mandated in neonates for prevention of gonococcal ophthalmia neonatorum in many states, including New York, where it can be administered without consent, according to Dr. Nguyen. Conversely, California does not mandate this preventive therapy even though the law does not offer medico-legal protection to providers if it is not given.

“There is a glaring gap in the way the [California] law was written,” said Dr. Nguyen, who used this as an example of why protocols and strategies to reduce risk of parental refusal of neonatal therapies should be informed by, and consistent with, state laws.

Because of the low levels of vitamin K in infants, the rate of bleeding within the first few months of life is nearly 2%, according to figures cited by Dr. Nguyen. It falls to less than 0.001% with administration of intramuscular vitamin K.

Families who refuse intramuscular vitamin K often state that they understand the risks, but data from a survey Dr. Nguyen cited found this is not necessarily true. In this survey, about two-thirds knew that bleeding was the risk, but less than 20% understood bleeding risks included intracranial hemorrhage, and less than 10% were aware that there was potential for a fatal outcome.

“This is a huge piece of the puzzle for counseling,” Dr. Nguyen said. “The discussion with parents should explicitly involve the explanation that the risks include brain bleeds and death.”

Although most infant bleeds attributed to low vitamin K stores are mucocutaneous or gastrointestinal, intracranial hemorrhage does occur, and these outcomes can be devastating. Up to 25% of infants who experience an intracranial hemorrhage die, while 60% of those who survive have some degree of neurodevelopmental impairment, according to Dr. Nguyen.

Oral vitamin K, which requires multiple doses, is not an appropriate substitute for the recommended single injection of the intramuscular formulation. The one study that compared intramuscular and oral vitamin K did not prove equivalence, and no oral vitamin K products have been approved by the Food and Drug Administration, Dr. Nguyen reported.

“We do know confidently that oral vitamin K does often result in poor adherence,” she said,

In a recent review article of parental vitamin K refusal, one of the most significant predictors of refusal of any recommended neonatal preventive treatment was refusal of another. According to data in that article, summarized by Dr. Nguyen, 68% of the parents who declined intramuscular vitamin K also declined erythromycin ointment, and more than 90% declined hepatitis B vaccine.

While SARS-CoV-2 causes frequent and potentially severe pulmonary disease, extrapulmonary manifestations may be a prominent part of the clinical spectrum, according to a review published in Nature Medicine.

In this comprehensive literature review, Aakriti Gupta, MD, of New York-Presbyterian/Columbia University Irving Medical Center and colleagues detailed the epidemiologic and clinical multisystem effects of COVID-19. The authors explained what is known and/or suspected about the pathophysiology of those effects and outlined the resultant management considerations.

Key mechanisms for multiorgan injury include direct viral toxicity, endothelial cell damage with inflammatory mediation of thrombosis, aberrant immune response, and dysregulation of the renin-angiotensin-aldosterone system.

The relative importance of each pathway in the clinical presentation of COVID-19 and the mechanism for extrapulmonary spread of SARS-CoV-2 infection are imperfectly understood, Dr. Gupta and colleagues noted.

As for the hematologic effects of COVID-19, patients may present with several laboratory abnormalities, but the most clinically relevant complications are thromboembolic.
 

COVID-19-associated coagulopathy

Dr. Gupta and colleagues noted that COVID-19–associated coagulopathy (CAC) is accompanied by elevated levels of D-dimer and fibrinogen, with minor abnormalities in prothrombin time, activated partial thromboplastin time, and platelet counts in the initial stage of infection.

Elevated D-dimer levels have been reported in up to 46% of hospitalized patients, and a longitudinal increase while hospitalized is associated with higher mortality.

In initial reports from China and the Netherlands, thrombotic complications were seen in up to 30% of COVID-19 patients in ICUs. Thromboembolic events have been reported in 17%-22% of critically ill COVID-19 patients in studies from Italy and France.

Globally, in severely affected COVID-19 patients, there have been reports of thromboses in intravenous catheters and extracorporeal circuits as well as arterial vascular occlusive events, including myocardial infarction, acute limb ischemia, and stroke.

There have been multiple small studies in which critically ill COVID-19 patients were routinely screened for thrombotic disease. In these studies, rates of thrombotic complications ranged from 69% to 85%, despite thromboprophylaxis. Variability in prophylactic and screening protocols explain discrepancies in event rates.
 

Pathophysiology

The abnormally high blood levels of D-dimer and fibrinogen during the early stages of SARS-CoV-2 infection are reflective of excessive inflammation rather than overt disseminated intravascular coagulation (DIC), which may develop in later stages of illness, according to Dr. Gupta and colleagues. The authors theorized that uninhibited inflammation, along with hypoxia and direct viral-mediated cellular injury, contribute to thrombotic complications in COVID-19 patients.

“The increased expression of ACE2 in endothelial cells after infection with SARS-CoV-2 may perpetuate a vicious cycle of endothelialitis that promotes thromboinflammation,” the authors wrote. “Collectively, hemostatic and inflammatory changes, which reflect endothelial damage and activation as well as critical illness, constitute a prothrombotic milieu.”

The authors noted that small autopsy series have shown high rates of microvascular and macrovascular thromboses, particularly in the pulmonary circulation, in COVID-19 patients.
 

Management considerations

Dr. Gupta and colleagues referenced interim guidelines from the International Society of Thrombosis and Haemostasis that recommend serial complete blood counts, with white blood cell differential and assessment of D-dimer, prothrombin time, and fibrinogen for hospitalized patients with COVID-19. The authors also cited guidelines published in the Journal of the American College of Cardiology that recommend routine risk assessment for venous thromboembolism in all hospitalized patients with COVID-19 and the consideration of standard-dose pharmaco-prophylaxis in patients who lack absolute contraindications.

Empiric use of higher-than-routine prophylactic-dose or therapeutic-dose anticoagulation in ICU patients in the absence of proven thromboses has been implemented in some institutions, Dr. Gupta and colleagues noted. Parenteral anticoagulants (such as low-molecular-weight or unfractionated heparin) are preferred to oral anticoagulants because of short half-life, available reversal agents, and the potential for drug interactions between oral agents and antiviral and/or antibacterial treatment, according to the authors.

They wrote that randomized clinical trials “will be crucial to establishing effective and safe strategies” for anticoagulation in COVID-19 patients. To this point, few randomized trials have been published to guide management of COVID-19–associated extrapulmonary manifestations, including CAC.
 

Research priorities

A more complete understanding of the organ-specific pathophysiology of this multisystem disease is vital, according to Dr. Gupta and colleagues.

Community of learners

As much as at any prior time in their careers, during the COVID-19 pandemic, health care providers have been enveloped in a community of learners – a group of people who share values and beliefs and who actively engage in learning from one another.

Through a patchwork of sources – news media, social media, traditional medical journals, general and COVID-focused meetings, and, most importantly, patients – we have been living in a learning-centered environment. Academicians, clinicians, practicing physicians, researchers, patients, family members, and caregivers have been actively and intentionally building a knowledge base together.

Through their published review, Dr. Gupta and colleagues have contributed meaningfully to the understanding our learning community has of the various extrapulmonary manifestations of COVID-19. The authors have provided a nice template for further research and clinical advances.

Dr. Gupta and colleagues disclosed financial relationships with a range of pharmaceutical companies and other organizations.

While SARS-CoV-2 causes frequent and potentially severe pulmonary disease, extrapulmonary manifestations may be a prominent part of the clinical spectrum, according to a review published in Nature Medicine.

In this comprehensive literature review, Aakriti Gupta, MD, of New York-Presbyterian/Columbia University Irving Medical Center and colleagues detailed the epidemiologic and clinical multisystem effects of COVID-19. The authors explained what is known and/or suspected about the pathophysiology of those effects and outlined the resultant management considerations.

Key mechanisms for multiorgan injury include direct viral toxicity, endothelial cell damage with inflammatory mediation of thrombosis, aberrant immune response, and dysregulation of the renin-angiotensin-aldosterone system.

The relative importance of each pathway in the clinical presentation of COVID-19 and the mechanism for extrapulmonary spread of SARS-CoV-2 infection are imperfectly understood, Dr. Gupta and colleagues noted.

As for the hematologic effects of COVID-19, patients may present with several laboratory abnormalities, but the most clinically relevant complications are thromboembolic.
 

COVID-19-associated coagulopathy

Dr. Gupta and colleagues noted that COVID-19–associated coagulopathy (CAC) is accompanied by elevated levels of D-dimer and fibrinogen, with minor abnormalities in prothrombin time, activated partial thromboplastin time, and platelet counts in the initial stage of infection.

Elevated D-dimer levels have been reported in up to 46% of hospitalized patients, and a longitudinal increase while hospitalized is associated with higher mortality.

In initial reports from China and the Netherlands, thrombotic complications were seen in up to 30% of COVID-19 patients in ICUs. Thromboembolic events have been reported in 17%-22% of critically ill COVID-19 patients in studies from Italy and France.

Globally, in severely affected COVID-19 patients, there have been reports of thromboses in intravenous catheters and extracorporeal circuits as well as arterial vascular occlusive events, including myocardial infarction, acute limb ischemia, and stroke.

There have been multiple small studies in which critically ill COVID-19 patients were routinely screened for thrombotic disease. In these studies, rates of thrombotic complications ranged from 69% to 85%, despite thromboprophylaxis. Variability in prophylactic and screening protocols explain discrepancies in event rates.
 

Pathophysiology

The abnormally high blood levels of D-dimer and fibrinogen during the early stages of SARS-CoV-2 infection are reflective of excessive inflammation rather than overt disseminated intravascular coagulation (DIC), which may develop in later stages of illness, according to Dr. Gupta and colleagues. The authors theorized that uninhibited inflammation, along with hypoxia and direct viral-mediated cellular injury, contribute to thrombotic complications in COVID-19 patients.

“The increased expression of ACE2 in endothelial cells after infection with SARS-CoV-2 may perpetuate a vicious cycle of endothelialitis that promotes thromboinflammation,” the authors wrote. “Collectively, hemostatic and inflammatory changes, which reflect endothelial damage and activation as well as critical illness, constitute a prothrombotic milieu.”

The authors noted that small autopsy series have shown high rates of microvascular and macrovascular thromboses, particularly in the pulmonary circulation, in COVID-19 patients.
 

Management considerations

Dr. Gupta and colleagues referenced interim guidelines from the International Society of Thrombosis and Haemostasis that recommend serial complete blood counts, with white blood cell differential and assessment of D-dimer, prothrombin time, and fibrinogen for hospitalized patients with COVID-19. The authors also cited guidelines published in the Journal of the American College of Cardiology that recommend routine risk assessment for venous thromboembolism in all hospitalized patients with COVID-19 and the consideration of standard-dose pharmaco-prophylaxis in patients who lack absolute contraindications.

Empiric use of higher-than-routine prophylactic-dose or therapeutic-dose anticoagulation in ICU patients in the absence of proven thromboses has been implemented in some institutions, Dr. Gupta and colleagues noted. Parenteral anticoagulants (such as low-molecular-weight or unfractionated heparin) are preferred to oral anticoagulants because of short half-life, available reversal agents, and the potential for drug interactions between oral agents and antiviral and/or antibacterial treatment, according to the authors.

They wrote that randomized clinical trials “will be crucial to establishing effective and safe strategies” for anticoagulation in COVID-19 patients. To this point, few randomized trials have been published to guide management of COVID-19–associated extrapulmonary manifestations, including CAC.
 

Research priorities

A more complete understanding of the organ-specific pathophysiology of this multisystem disease is vital, according to Dr. Gupta and colleagues.

“Regional, national, and international collaborations of clinicians and scientists focused on high-quality, transparent, ethical, and evidence-based research practices would help propel the global community toward achieving success against this pandemic,” the authors wrote.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors used for the treatment of type 2 diabetes, and for heart failure, are associated with a nearly threefold increased risk for diabetic ketoacidosis (DKA), according to a new large database analysis.

Boarding1Now/Thinkstock

The findings, which include data on the use of three different SGLT2 inhibitors in Canada and the United Kingdom and suggest a class effect, were published online July 27 in Annals of Internal Medicine by Antonios Douros, MD, PhD, of McGill University and the Centre for Clinical Epidemiology, Lady Davis Institute, Montreal, and colleagues.

“Our results provide robust evidence that SGLT2 inhibitors are associated with an increased risk for DKA. Of note, increased risks were observed in all molecule-specific analyses, with canagliflozin [Invokana, Janssen] showing the highest effect estimate,” they noted.

And because the beneficial effects of SGLT2 inhibitors in the prevention of cardiovascular and renal disease will probably increase their uptake in the coming years, “Physicians should be aware of DKA as a potential adverse effect,” Dr. Douros and colleagues wrote.
 

Analysis “generally confirms what has already been published”

Asked for comment, Simeon I. Taylor, MD, PhD, professor of medicine at the University of Maryland, Baltimore, said that the study “generally confirms what has already been published” on the topic. He noted that overall “the risk of SGLT2 inhibitor–induced ketoacidosis is quite low in type 2 diabetes, perhaps on the order of 1 episode per 1000 patient-years.”

However, Dr. Taylor cautioned: “Published evidence suggests that the risk of DKA is increased if patients are unable to eat,” such as when hospitalized patients are not permitted to eat.

“In that setting, it is probably prudent to discontinue an SGLT2 inhibitor. Also, it may be prudent not to prescribe SGLT2 inhibitors to patients with a history of DKA,” he added.

Dr. Taylor also advised: “Although not necessarily supported by this publication, I think that caution should be exercised in prescribing SGLT2 inhibitors to insulin-dependent type 2 diabetes patients. ... Some late-stage type 2 diabetes patients may have severe insulin deficiency, and their physiology may resemble that of a type 1 diabetes patient.”

Dr. Taylor has previously advised against using SGLT2 inhibitors altogether in patients with type 1 diabetes.
 

Increased DKA risk seen across all SGLT2 inhibitors

The study involved electronic health care databases from seven Canadian provinces and the United Kingdom, from which 208,757 new users of SGLT2 inhibitors were propensity-matched 1:1 to new dipeptidyl peptidase-4 (DPP-4) inhibitor users.

Of those taking an SGLT2 inhibitor, 42.3% took canagliflozin, 30.7% dapagliflozin (Farxiga/Forxiga, AstraZeneca), and 27.0% empagliflozin (Jardiance, Boehringer Ingelheim).

Over a mean 0.9-year follow-up, 521 patients were hospitalized with DKA, for an overall incidence rate of 1.41 per 1,000 person-years.

The rate with SGLT2 inhibitors, 2.03 per 1,000 person-years, was nearly three times that seen with DPP-4 inhibitors, at 0.75 per 1,000 person-years, a significant difference (hazard ratio, 2.85).

By individual SGLT2 inhibitor, the hazard ratios compared with DPP-4 inhibitors were 1.86 for dapagliflozin, 2.52 for empagliflozin, and 3.58 for canagliflozin, all statistically significant. Stratification by age, sex, and incident versus prevalent user did not change the association between SGLT2 inhibitors and DKA.

Asked about the higher rate for canagliflozin, Dr. Taylor commented: “It is hard to know whether there are real and reproducible differences in the risks of DKA among the various SGLT2 inhibitors. The differences are not huge and the populations are not well matched.”

But, he noted, “If canagliflozin triggers more glucosuria, it is not surprising that it would also induce more ketosis and possibly ketoacidosis.”

He also noted that the threefold relative increase in DKA with canagliflozin versus comparators is consistent with Janssen’s data, published in 2015. 

“It is, of course, reassuring that both [randomized clinical trials] and epidemiology produce similar estimates of the risk of drug-induced adverse events. Interestingly, the incidence of DKA is approximately threefold higher in the Canadian [data] as compared to Janssen’s clinical trials.”

Dr. Taylor also pointed out that, in the Janssen studies, the risk of canagliflozin-induced DKA appeared to be higher among patients with anti-islet antibodies, which suggests that some may have actually had autoimmune (type 1) diabetes. “So the overall risk of SGLT2 inhibitor-induced DKA may depend at least in part on the mix of patients.”

In the current study, individuals who never used insulin had a greater relative increase in risk of DKA with SGLT2 inhibitors, compared with DPP-4 inhibitors, than did those who did use insulin (hazard ratios, 3.96 vs. 2.24, both compared with DPP-4 inhibitors). However, just among those taking SGLT2 inhibitors, the absolute risk for DKA was higher for those with prior insulin use (3.52 vs. 1.43 per 1,000 person-years). 

The results of sensitivity analyses were consistent with those of the primary analysis.

The study was funded by the Canadian Institutes of Health Research and supported by ICES. Dr. Douros has reported receiving a salary support award from Fonds de recherche du Quebec – sante. Dr. Taylor was previously employed at Bristol-Myers Squibb. He is currently a consultant for Ionis Pharmaceuticals and has reported receiving research support provided to the University of Maryland School of Medicine by Regeneron.

One of the take-away messages from a review of multisystem inflammatory syndrome in children (MIS-C) is that clinicians treating this condition “need to be comfortable with uncertainty,” Melissa Hazen, MD, said at a synthesis of multiple published case series and personal experience summarized at the virtual Pediatric Hospital Medicine meeting.

She emphasized MIS-C patient care “requires flexibility,” and she advised clinicians managing these patients to open the lines of communication with the many specialists who often are required to deal with complications affecting an array of organ systems.

MIS-C might best be understood as the most serious manifestation of an immune-mediated response to COVID-19 infection that ranges from transient mild symptoms to the life-threatening multiple organ involvement that characterizes this newly recognized threat. Although “most children who encounter this pathogen only develop mild disease,” the spectrum of the disease can move in a subset of patients to a “Kawasaki-like illness” without hemodynamic instability and then to MIS-C “with highly elevated systemic inflammatory markers and multiple organ involvement,” explained Dr. Hazen, an attending physician in the rheumatology program at Boston Children’s Hospital.

A reliable profile of MIS-C is only beginning to emerge from the series of published case series, most of which have only recently reached publication, according to Dr. Hazen. In general, the description of the most common symptoms and their course has been relatively consistent.

In 186 cases of MIS-C collected in a study funded by the Centers for Disease Control and Prevention, 148 (80%) were admitted to intensive care, 90 patients (48%) received vasoactive support, 37 (20%) received mechanical ventilation, and 4 (2%) died.¹ The median age was 8 years (range, 3-13 years) in this study. The case definition was fever for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of COVID-19 infection. In this cohort of 186 children, 92% had gastrointestinal, 80% had cardiovascular, 76% had hematologic, and 70% had respiratory system involvement.

In a different series of 95 cases collected in New York State, 79 (80%) were admitted to intensive care, 61 (62%) received vasoactive support, 10 (10%) received mechanical ventilation, 4 (4%) received extracorporeal membrane oxygenation (ECMO), and 2 (2%) died. ² Thirty-one percent patients were aged 0-5 years, 42% were 6-12 years, and 26% were 13-20 years of age. In that series, for which the case definition was elevation of two or more inflammatory markers, virologic evidence of COVID-19 infection, 80% had gastrointestinal system involvement, and 53% had evidence of myocarditis.

In both of these series, as well as others published and unpublished, the peak in MIS-C cases has occurred about 3 to 4 weeks after peak COVID-19 activity, according to Diana Lee, MD, a pediatrician at Icahn School of Medicine at Mount Sinai, New York. This pattern, reported by others, was observed in New York State, where 230 cases of MIS-C were collected from the beginning of May until the end of June, which reflected this 3- to 4-week delay in peak incidence.

“This does seem to be a rare syndrome since this [group of] 230 cases is amongst the entire population of children in New York State. So, yes, we should be keeping this in mind in our differential, but we should not forget all the other reasons that children can have a fever,” she said.

Both Dr. Hazen and Dr. Lee cautioned that MIS-C, despite a general consistency among published studies, remains a moving target in regard to how it is being characterized. In a 2-day period in May, the CDC, the World Health Organization, and New York State all issued descriptions of MIS-C, employing compatible but slightly different terminology and diagnostic criteria. Many questions regarding optimal methods of diagnosis, treatment, and follow-up remain unanswered.

Questions regarding the risk to the cardiovascular system, one of the organs most commonly affected in MIS-C, are among the most urgent. It is not now clear how best to monitor cardiovascular involvement, how to intervene, and how to follow patients in the postinfection period, according to Kevin G. Friedman, MD, a pediatrician at Harvard Medical School, Boston, and an attending physician in the department of cardiology at Boston Children’s Hospital.

“The most frequent complication we have seen is ventricular dysfunction, which occurs in about half of these patients,” he reported. “Usually it is in the mild to moderate range, but occasionally patients have an ejection fraction of less than 40%.”

Coronary abnormalities, typically in the form of dilations or small aneurysms, occur in 10%-20% of children with MIS-C, according to Dr. Friedman. Giant aneurysms have been reported.

“Some of these findings can progress including in both the acute phase and, particularly for the coronary aneurysms, in the subacute phase. We recommend echocardiograms and EKGs at diagnosis and at 1-2 weeks to recheck coronary size or sooner if there are clinical indications,” Dr. Friedman advised.

Protocols like these are constantly under review as more information becomes available. There are as yet no guidelines, and practice differs across institutions, according to the investigators summarizing this information.

None of the speakers had any relevant financial disclosures.

One of the take-away messages from a review of multisystem inflammatory syndrome in children (MIS-C) is that clinicians treating this condition “need to be comfortable with uncertainty,” Melissa Hazen, MD, said at a synthesis of multiple published case series and personal experience summarized at the virtual Pediatric Hospital Medicine meeting.

She emphasized MIS-C patient care “requires flexibility,” and she advised clinicians managing these patients to open the lines of communication with the many specialists who often are required to deal with complications affecting an array of organ systems.

MIS-C might best be understood as the most serious manifestation of an immune-mediated response to COVID-19 infection that ranges from transient mild symptoms to the life-threatening multiple organ involvement that characterizes this newly recognized threat. Although “most children who encounter this pathogen only develop mild disease,” the spectrum of the disease can move in a subset of patients to a “Kawasaki-like illness” without hemodynamic instability and then to MIS-C “with highly elevated systemic inflammatory markers and multiple organ involvement,” explained Dr. Hazen, an attending physician in the rheumatology program at Boston Children’s Hospital.

A reliable profile of MIS-C is only beginning to emerge from the series of published case series, most of which have only recently reached publication, according to Dr. Hazen. In general, the description of the most common symptoms and their course has been relatively consistent.

In 186 cases of MIS-C collected in a study funded by the Centers for Disease Control and Prevention, 148 (80%) were admitted to intensive care, 90 patients (48%) received vasoactive support, 37 (20%) received mechanical ventilation, and 4 (2%) died.¹ The median age was 8 years (range, 3-13 years) in this study. The case definition was fever for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of COVID-19 infection. In this cohort of 186 children, 92% had gastrointestinal, 80% had cardiovascular, 76% had hematologic, and 70% had respiratory system involvement.

Laurent Duvernay-Tardif, MD, the only medical doctor on a current NFL roster, has become the first player to opt out of the 2020 NFL season, citing concerns over risk for COVID-19.

Canadian-born Duvernay-Tardif, right guard for the Kansas City Chiefs, announced on Twitter on July 24 what he called “one of the most difficult decisions I have had to make in my life.”

“There is no doubt in my mind the Chiefs’ medical staff have put together a strong plan to minimize the health risks associated with COVID-19, but some risks will remain,” he posted.

“Being at the frontline during this offseason has given me a different perspective on this pandemic and the stress it puts on individuals and our healthcare system. I cannot allow myself to potentially transmit the virus in our communities simply to play the sport that I love. If I am to take risks, I will do it caring for patients.”

According to CNN, Duvernay-Tardif, less than 3 months after helping the Chiefs win the Super Bowl in February, began working at a long-term care facility near Montreal in what he described as a “nursing role.”

Duvernay-Tardif wrote recently in an article for Sports Illustrated that he has not completed his residency and is not yet licensed to practice.

“My first day back in the hospital was April 24,” Duvernay-Tardif wrote. “I felt nervous the night before, but a good nervous, like before a game.”

Duvernay-Tardif has also served on the NFL Players’ Association COVID-19 task force, according to Yahoo News .

A spokesperson for Duvernay-Tardif told Medscape Medical News he was unavailable to comment about the announcement.

Starting His Dual Career

Duvernay-Tardif, 29, was drafted in the sixth round by the Chiefs in 2014.

According to Forbes , he spent 8 years (2010-2018) pursuing his medical degree while still playing college football for McGill University in Montreal. Duvernay-Tardif played offensive tackle for the Redmen and in his senior year (2013) won the Metras Trophy as most outstanding lineman in Canadian college football.

He explained in a previous Medscape interview how he managed his dual career; as a doctor he said he would like to focus on emergency medicine:

“I would say that at around 16-17 years of age, I was pretty convinced that medicine was for me,” he told Medscape.

“I was lucky that I didn’t have to do an undergrad program,” he continued. “In Canada, they have a fast-track program where instead of doing a full undergrad before getting into medical school, you can do a 1-year program where you can do all your physiology and biology classes all together.

“I had the chance to get into that program, and that’s how I was able to manage football and medicine at the same time. There’s no way I could have finished my med school doing part-time med school like I did for the past 4 years.”

ESPN explained the opt-out option: “According to an agreement approved by both the league and the union on [July 24], players considered high risk for COVID-19 can earn $350,000 and an accrued NFL season if they choose to opt out of the 2020 season. Players without risk can earn $150,000 for opting out. Duvernay-Tardif was scheduled to make $2.75 million this season.”

The danger of COVID-19 in professional sports has already been seen in Major League Baseball.

According to USA Today, the Miami Marlins have at least 14 players and staff who have tested positive for COVID-19, and major league baseball Commissioner Rob Manfred must decide whether to further delay the shortened season, cancel it, or allow it to continue.

MLB postponed the Marlins’ home opener July 27 against the Baltimore Orioles as well as the New York Yankees game in Philadelphia against the Phillies.

COVID-19 also shut down professional, college, high school, and recreational sports throughout much of the country beginning in March.

Medicine, Football Intersect

In the previous Medscape interview, Duvernay-Tardif talked about how medicine influenced his football career.

“For me, medicine was really helpful in the sense that I was better able to build a routine and question what works for me and what doesn’t. It gave me the ability to structure my work in order to optimize my time and to make sure that it’s pertinent.

“Another thing is the psychology and the sports psychology. I think there’s a little bit of a stigma around mental health issues in professional sports and everywhere, actually. I think because of medicine, I was more willing to question myself and more willing to use different tools in order to be a better football player.”
