COVID-19 Literature Situation Report Sept. 30, 2020

Category:

The scientific literature on COVID-19 is rapidly evolving and these articles were selected for review based on their relevance to Washington State decision making around COVID-19 response efforts. Included in these Lit Reps are some manuscripts that have been made available online as pre-prints but have not yet undergone peer review. Please be aware of this when reviewing articles included in the Lit Reps.

Today’s summary is based on a review of 634 articles (595 published, 39 in preprint).

Key Takeaways

  • Among patients hospitalized with COVID-19 in the US, prior psychiatric diagnosis was associated with a higher mortality rate after controlling for demographic characteristics, other comorbidities, and hospital locations. More
  • Daily hydroxychloroquine administration to healthcare workers as pre-exposure prophylaxis against SARS-CoV-2 infection did not change infection risk, although this double-blind placebo-controlled randomized trial was ended early and may be underpowered. More
  • Nearly half of residents diagnosed with COVID-19 in a long-term care facility in Boston were asymptomatic at the time of diagnosis, emphasizing the importance of universal testing rather than symptom-based screening to control outbreaks in similar settings. More
  • The Abbott ID NOW diagnostic test for SARS-CoV-2 RNA performed significantly worse than similar tests, particularly in samples with low viral load and in nasal swab samples (vs nasopharyngeal samples). More

Testing and Treatment

Risk of COVID-19-Related Death among Patients with Chronic Obstructive Pulmonary Disease or Asthma Prescribed Inhaled Corticosteroids: An Observational Cohort Study Using the OpenSAFELY Platform

  • In a large cohort of people with chronic obstructive pulmonary disease (COPD) in the UK (n=148,557), and asthma (818,490), Schultze et al. found an increased risk of COVID-19 related death associated with use of inhaled corticosteroids, compared to other commonly-used medications.
  • The authors note that the observed increased risks could be attributed to unmeasured confounding due to disease severity. They further note that the results do not support the regular use of inhaled corticosteroids for protection against COVID-19 mortality in people with COPD or asthma.

Reliability of Serological Tests for COVID-19: Comparison of Three Immunochromatography Test Kits for SARS-CoV-2 Antibodies

  • Three commercially available serological test kits using immunochromatography (Hangzhou AllTest, SD BIOSENSOR, and Vazyme) were evaluated using identical sample sets consisting of 99 serum samples from SARS-CoV-2 positive patients and 100 serum samples from healthy volunteers in 2017. All test kits achieved >97% specificity for IgM and IgG and >97% sensitivity to IgG at 13 days after symptom onset. Sensitivity to IgM after 4 days varied, with both Hangzhou and Vazyme unable to achieve values >33.3%.

The Role of Anti-Hypertensive Treatment, Comorbidities and Early Introduction of LMWH in the Setting of COVID-19: A Retrospective, Observational Study in Northern Italy

  • Chronic treatment with the antihypertensive medications angiotensin converting enzyme inhibitors (ACE-I) and early treatment with low-molecular-weight heparin (LMWH) were both associated with lower in-hospital mortality in a cohort of patients hospitalized with COVID-19 in Italy (n=575), after adjusting for age. Angiotensin receptor blockers, which are also antihypertensive agents acting on the same physiological pathway, were not associated with differences in mortality.

Comparative Study of Four SARS-CoV-2 Nucleic Acid Amplification Test (NAAT) Platforms Demonstrates That ID NOW Performance Is Impaired Substantially by Patient and Specimen Type

  • The nucleic acid amplification test (NAAT) platform Abbott ID NOW performed significantly worse than similar tests (Abbott m2000, DiaSorine Simplexa, and Cepheid Xpert) in detecting SARS-CoV-2 RNA in a comparative study. All four tests were used in parallel on nasopharyngeal and nasal samples from 88 emergency department and hospital-admitted patients. In particular, the ID NOW platform performed poorly in samples with a low viral load (high cycle time) that were detected as positive by the other tests.

Efficacy and Safety of Hydroxychloroquine vs Placebo for Pre-Exposure SARS-CoV-2 Prophylaxis Among Health Care Workers

  • Daily administration of hydroxychloroquine to hospital-based healthcare workers as pre-exposure prophylaxis against SARS-CoV-2 infection did not change infection risk between participants receiving hydroxychloroquine vs placebo (6.3% vs 6.6%, p>0.99) in this randomized, double-blind, placebo-controlled trial (n=132).
  • The trial was terminated early due to futility and may have been underpowered to detect clinically important differences.

Clinical Characteristics and Health Care Setting

Angiotensin-Converting Enzyme 2 (ACE2) Levels in Relation to Risk Factors for COVID-19 in Two Large Cohorts of Patients with Atrial Fibrillation

  • Male sex, cardiovascular disease, diabetes, and biomarker indicators of biological aging were associated with higher levels of soluble angiotensin-converting enzyme 2 (sACE2) among two international cohorts of elderly patients with atrial fibrillation. Higher levels of sACE2 could reflect a higher cellular expression of ACE2, a cellular receptor by which SARS-CoV-2 enters human cells, and thus pose as higher risk for severe COVID-19 infection.

Risk Factors, Presentation, and Course of Coronavirus Disease 2019 in a Large, Academic Long-Term Care Facility

  • Nearly half (46%) of the 146 out of 389 residents of a long-term care facility who were diagnosed with COVID-19 were asymptomatic at the time of diagnosis, emphasizing the importance of universal testing rather than symptom-based testing to control outbreaks. Anorexia and delirium where the most common symptoms during the course of illness. Male sex and bowel incontinence were predictors of COVID-19 diagnosis among residents. A greater proportion of staff per unit who lived in a community with a high prevalence of COVID-19 was also associated with greater risk of SARS-CoV-2 infection among residents.

Association of a Prior Psychiatric Diagnosis With Mortality Among Hospitalized Patients With Coronavirus Disease 2019 (COVID-19) Infection

  • Among a cohort of hospitalized patients with COVID-19 in the US (n=1685), the risk of death remained significantly greater among patients with a psychiatric disorder after controlling for demographic characteristics, other medical comorbidities, and hospital location.

Mental Health and Personal Impact

Maternal Mental Health and Coping during the COVID‐19 Lockdown in the UK: Data from the COVID‐19 New Mum Study

  • Among surveyed women living in the UK with an infant aged ≤12 months (n=1,329), a majority reported feeling down (56%), lonely (59%), irritable (62%), and worried (71%) since the beginning of lockdown, but 70% felt able to cope. Having support with her own health, contacting infant support groups, and higher gestational age of the infant were associated with better mental health, while travelling for work, lockdown effects on ability to afford food, and having an annual income less than £30,000 were associated with poorer mental health.

Modeling and Prediction

The Potential Contribution of Face Coverings to the Control of SARS-CoV-2 Transmission in Schools and Broader Society in the UK a Modelling Study

  • [Pre-print, not peer-reviewed] A modeling study shows that adoption of masks in secondary schools and community settings under current test-trace-isolate (TTI) levels could reduce the size of a second wave in the UK but not prevent it. Under current tracing levels, and at effective mask coverage of 30%, 46% of those with symptomatic infection would need to be tested to avoid a second wave.

COVID-19 among People Experiencing Homelessness in England: A Modelling Study

  • A modeling study found that continuing measures to prevent SARS-CoV-2 infection among people experiencing homelessness would result in a small projected number of cases and deaths (1754 infections, 31 deaths) in the context of a second wave of SARS-CoV-2 infection in the general population (June 2020 to January 2021). However, in a scenario with no second wave and a lifting of preventive measures, the authors project 12,151 infections and 184 deaths, suggesting that homeless settings might experience outbreaks even if incidence remains low in the general population.

Comparison of Infection Control Strategies to Reduce COVID-19 Outbreaks in Homeless Shelters in the United States a Simulation Study

  • [Pre-print, not peer-reviewed] A microsimulation model calibrated to PCR data from outbreaks in 5 homeless shelters found that while infection control strategies can prevent outbreaks in low-risk settings, they may be unlikely to do so in high-risk settings. The model found that in shelters with low (R0 = 1.5), moderate (R0 = 2.9), and high (R0 = 6.2) risk of transmission, the probability of averting an outbreak over 30 days given the use of combined daily symptom-based screening was 0.68, twice-weekly PCR testing was 0.40, and universal masking was 0.08.
