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.

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.

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.

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.

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. The authors report no relevant financial disclosures. Dr. Femia and Dr. Friedman had no relevant financial disclosures.

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.

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.

Recent research has shown that social cognition training can benefit patients with schizophrenia, and a new study suggests that adding regular aerobic exercise sessions substantially increases the improvements in a dose-response manner.

kaspiic/thinkstockphotos.com

In a randomized controlled trial (RCT) in 47 patients with schizophrenia, improvement in cognition tripled after adding an aerobic exercise program to cognitive training (CT) compared with CT alone.

Investigators, led by Keith H. Nuechterlein, PhD, professor of psychology, University of California, Los Angeles, note that there is “increasing evidence” to support the use of aerobic exercise to improve cognition and functioning in schizophrenia.

However, the “extent to which these gains are dependent on the amount of aerobic exercise completed remains unclear, although variability in adherence to intended exercise regiments is evident,” they write.

They also point out that strategies to encourage regular exercise in patients with schizophrenia “are only starting to be explored.”

The findings were scheduled to be presented at the Congress of the Schizophrenia International Research Society (SIRS) 2020, but the meeting was canceled because of the coronavirus pandemic.

Body Circuit Training

In the study, 47 patients with first-episode schizophrenia were randomly assigned to receive 6 months of CT alone or 6 months of CT plus exercise (CT+E).

All participants underwent 4 hours per week of computerized CT with BrainHQ and SocialVille programs (PositScience).

Patients in the CT+E group also took part in total body circuit training. Two aerobic exercise sessions per week were held at the clinic and two were to be completed at home. The goal was 150 minutes of exercise per week in total.

Exercise intensity was titrated to the individual, at a target of 60% to 80% of heart rate reserve.

Both the CT and CT+E groups showed cognitive gains on the MATRICS Consensus Cognitive Battery (MCCB) test, as well as work/school functioning gains on the Global Assessment Scale: Role.

However, results showed that the improvements in the CT+E group were three times greater than those shown in the CT group (P < .02 for the MCCB overall composite score).

Cognitive Gain Predictors

Because there were also substantial differences in the magnitude of cognitive improvement between the CT+E patients, the investigators sought to identify predictors of cognitive gain.

They found that patients in the CT+E group completed, on average, 85% of their in-clinic exercise sessions but only 39% of their home exercise sessions.

Those who completed a higher overall proportion of the exercise sessions had the largest cognitive gains (P = .03). This relationship was even stronger for patients who completed home exercise sessions (P = .02).

“Thus, aerobic exercise showed a dose-response relationship to cognitive improvement,” the researchers report.

To improve completion rates for home sessions, the investigators tried paying the patients $5 for each session completed, which was “helpful” but did not iron out the variability in adherence.

They also tried assigning points for completing the most exercise sessions in the desired heart rate. They awarded a monthly winner and divided the patients into two completion groups. However, there were “mixed” results.

“Development of systematic incentive strategies to encourage regular aerobic exercise will be critical to successful dissemination of exercise programs as part of the treatment of schizophrenia,” the researchers write.

They add that “pilot work with smartphone reminder systems is underway.”

Effective, but Intensity Is Key

Commenting on the study for Medscape Medical News, David Kimhy, PhD, program leader for New Interventions in Schizophrenia, Department of Psychiatry, Icahn School of Medicine at Mount Sinai, New York City, said the results are consistent with previous research.  

Aerobic exercise is “highly effective in improving neurocognitive functioning” in patients with schizophrenia, said Kimhy, who was not involved in the research.

“Many individuals with schizophrenia tend to have a highly sedentary lifestyle resulting in poor aerobic fitness,” he said. “Thus, aerobic fitness may represent one of the few modifiable risk factors for ameliorating poor neurocognitive functioning.”

He noted that those benefits are in addition to “the many cardiovascular and health benefits aerobic exercise provide, which are nearly nonexistent for cognitive training and pharmacological interventions.”

However, even if patients do take part in exercise sessions, “an important issue is in-session fidelity with training goals, as individuals may attend scheduled sessions but exercise very lightly,” Kimhy noted.

He pointed out that the proportion of time these patients exercise at their designated target training intensity is highly correlated with neurocognitive improvement. Consequently, “exercising with a trainer may increase both attendance and in-session training fidelity.”

Overall, although the current study suggests that in-clinic exercise sessions can be advantageous, “the recent COVID-19 pandemic made such options very challenging,” Kimhy said.

“To address this issue, our research group and others are currently examining employment of aerobic exercise training at home, connected with trainers via live two-way telehealth video calls,” he added.

Plasticity-Based Training

Two recent studies also indicate that remotely administered training programs can improve social cognition.

In the first study, published online July 2 in Schizophrenia Bulletin, 147 outpatients with schizophrenia were randomly assigned to complete 40 sessions of either SocialVille plasticity-based social cognition training or computer-based games such as crossword puzzles and solitaire.

“To develop these social cognition training exercises, we analyzed a tremendous amount of prior research about how the brain processes social information,” lead author Mor Nahum, PhD, School of Occupational Therapy, Hebrew University, Jerusalem, Israel, said in a press release.

“It turns out that social cognition requires fast and accurate brain information processing, so we developed exercises that trained the brain to process social stimuli, like faces and emotions, quickly and accurately,” Nahum added.

The interventions were conducted at home, with 55 participants completing the cognitive training and 53 completing the computer game sessions. (The remaining 39 either dropped out or withdrew.)

An average of 28 hours of social cognition training over 3 months was associated with a significant improvement on social cognitive composite scores compared with computer games (P < .001), but not on the UCSD Performance-Based Skills Assessment.

Further analysis suggested that more time spent on the cognitive training was associated with greater improvements in social cognition and social functioning, as well as on a motivation subscale.

The results “provide support for the efficacy of a remote, plasticity-based social cognitive training program,” the investigators write.

Such programs “may serve as a cost-effective adjunct to existing psychosocial treatments,” they add.

Auditory vs Visual Training

In the other study, published online May 21 in Schizophrenia Research, investigators led by Rogerio Panizzutti, MD, PhD, Instituto de Ciencias Biomedicas, Federal University of Rio de Janeiro, Brazil, randomly assigned 79 patients with schizophrenia to 40 hours of auditory or visual computerized training.

The exercises were dynamically equivalent between the two types of training, and their difficulty increased as the training progressed.

Both groups showed improvements in reasoning, problem-solving, and reported symptoms. However, the group receiving visual training also had greater improvement in global cognition and attention than the group receiving auditory training. 

All studies were supported by Posit Science Corporation. The study authors and Kimhy have disclosed no relevant financial relationships.

An average of 28 hours of social cognition training over 3 months was associated with a significant improvement on social cognitive composite scores compared with computer games (P < .001), but not on the UCSD Performance-Based Skills Assessment.

Further analysis suggested that more time spent on the cognitive training was associated with greater improvements in social cognition and social functioning, as well as on a motivation subscale.

The results “provide support for the efficacy of a remote, plasticity-based social cognitive training program,” the investigators write.

Such programs “may serve as a cost-effective adjunct to existing psychosocial treatments,” they add.

Auditory vs Visual Training

In the other study, published online May 21 in Schizophrenia Research, investigators led by Rogerio Panizzutti, MD, PhD, Instituto de Ciencias Biomedicas, Federal University of Rio de Janeiro, Brazil, randomly assigned 79 patients with schizophrenia to 40 hours of auditory or visual computerized training.

The exercises were dynamically equivalent between the two types of training, and their difficulty increased as the training progressed.

Both groups showed improvements in reasoning, problem-solving, and reported symptoms. However, the group receiving visual training also had greater improvement in global cognition and attention than the group receiving auditory training.

Recent research has shown that social cognition training can benefit patients with schizophrenia, and a new study suggests that adding regular aerobic exercise sessions substantially increases the improvements in a dose-response manner.

In a randomized controlled trial (RCT) in 47 patients with schizophrenia, improvement in cognition tripled after adding an aerobic exercise program to cognitive training (CT) compared with CT alone.

Investigators, led by Keith H. Nuechterlein, PhD, professor of psychology, University of California, Los Angeles, note that there is “increasing evidence” to support the use of aerobic exercise to improve cognition and functioning in schizophrenia.

However, the “extent to which these gains are dependent on the amount of aerobic exercise completed remains unclear, although variability in adherence to intended exercise regiments is evident,” they write.

They also point out that strategies to encourage regular exercise in patients with schizophrenia “are only starting to be explored.”

The findings were scheduled to be presented at the Congress of the Schizophrenia International Research Society (SIRS) 2020, but the meeting was canceled because of the coronavirus pandemic.

Body Circuit Training

In the study, 47 patients with first-episode schizophrenia were randomly assigned to receive 6 months of CT alone or 6 months of CT plus exercise (CT+E).

All participants underwent 4 hours per week of computerized CT with BrainHQ and SocialVille programs (PositScience).

Patients in the CT+E group also took part in total body circuit training. Two aerobic exercise sessions per week were held at the clinic and two were to be completed at home. The goal was 150 minutes of exercise per week in total.

Exercise intensity was titrated to the individual, at a target of 60% to 80% of heart rate reserve.

Both the CT and CT+E groups showed cognitive gains on the MATRICS Consensus Cognitive Battery (MCCB) test, as well as work/school functioning gains on the Global Assessment Scale: Role.

However, results showed that the improvements in the CT+E group were three times greater than those shown in the CT group (P < .02 for the MCCB overall composite score).

Cognitive Gain Predictors

Because there were also substantial differences in the magnitude of cognitive improvement between the CT+E patients, the investigators sought to identify predictors of cognitive gain.

They found that patients in the CT+E group completed, on average, 85% of their in-clinic exercise sessions but only 39% of their home exercise sessions.

Those who completed a higher overall proportion of the exercise sessions had the largest cognitive gains (P = .03). This relationship was even stronger for patients who completed home exercise sessions (P = .02).

“Thus, aerobic exercise showed a dose-response relationship to cognitive improvement,” the researchers report.

To improve completion rates for home sessions, the investigators tried paying the patients $5 for each session completed, which was “helpful” but did not iron out the variability in adherence.

They also tried assigning points for completing the most exercise sessions in the desired heart rate. They awarded a monthly winner and divided the patients into two completion groups. However, there were “mixed” results.

“Development of systematic incentive strategies to encourage regular aerobic exercise will be critical to successful dissemination of exercise programs as part of the treatment of schizophrenia,” the researchers write.

They add that “pilot work with smartphone reminder systems is underway.”

Effective, but Intensity Is Key

Commenting on the study for Medscape Medical News, David Kimhy, PhD, program leader for New Interventions in Schizophrenia, Department of Psychiatry, Icahn School of Medicine at Mount Sinai, New York City, said the results are consistent with previous research.  

Aerobic exercise is “highly effective in improving neurocognitive functioning” in patients with schizophrenia, said Kimhy, who was not involved in the research.

“Many individuals with schizophrenia tend to have a highly sedentary lifestyle resulting in poor aerobic fitness,” he said. “Thus, aerobic fitness may represent one of the few modifiable risk factors for ameliorating poor neurocognitive functioning.”

He noted that those benefits are in addition to “the many cardiovascular and health benefits aerobic exercise provide, which are nearly nonexistent for cognitive training and pharmacological interventions.”

However, even if patients do take part in exercise sessions, “an important issue is in-session fidelity with training goals, as individuals may attend scheduled sessions but exercise very lightly,” Kimhy noted.

He pointed out that the proportion of time these patients exercise at their designated target training intensity is highly correlated with neurocognitive improvement. Consequently, “exercising with a trainer may increase both attendance and in-session training fidelity.”

Overall, although the current study suggests that in-clinic exercise sessions can be advantageous, “the recent COVID-19 pandemic made such options very challenging,” Kimhy said.

“To address this issue, our research group and others are currently examining employment of aerobic exercise training at home, connected with trainers via live two-way telehealth video calls,” he added.

Plasticity-Based Training

Two recent studies also indicate that remotely administered training programs can improve social cognition.

In the first study, published online July 2 in Schizophrenia Bulletin, 147 outpatients with schizophrenia were randomly assigned to complete 40 sessions of either SocialVille plasticity-based social cognition training or computer-based games such as crossword puzzles and solitaire.

“To develop these social cognition training exercises, we analyzed a tremendous amount of prior research about how the brain processes social information,” lead author Mor Nahum, PhD, School of Occupational Therapy, Hebrew University, Jerusalem, Israel, said in a press release.

“It turns out that social cognition requires fast and accurate brain information processing, so we developed exercises that trained the brain to process social stimuli, like faces and emotions, quickly and accurately,” Nahum added.

The interventions were conducted at home, with 55 participants completing the cognitive training and 53 completing the computer game sessions. (The remaining 39 either dropped out or withdrew.)

An average of 28 hours of social cognition training over 3 months was associated with a significant improvement on social cognitive composite scores compared with computer games (P < .001), but not on the UCSD Performance-Based Skills Assessment.

Further analysis suggested that more time spent on the cognitive training was associated with greater improvements in social cognition and social functioning, as well as on a motivation subscale.

The results “provide support for the efficacy of a remote, plasticity-based social cognitive training program,” the investigators write.

Such programs “may serve as a cost-effective adjunct to existing psychosocial treatments,” they add.

The exercises were dynamically equivalent between the two types of training, and their difficulty increased as the training progressed.

Both groups showed improvements in reasoning, problem-solving, and reported symptoms. However, the group receiving visual training also had greater improvement in global cognition and attention than the group receiving auditory training.
