Characterization of the risk factors associated with variability in the clinical outcomes of COVID-19 is important. Our previous study using genomic data identified a potential role of calcium and lipid homeostasis in severe COVID-19. This study aimed to identify similar combinations of features (disease signatures) associated with severe disease in a separate patient population with purely clinical and phenotypic data. The PrecisionLife combinatorial analytics platform was used to analyze features derived from de-identified health records in the UnitedHealth Group COVID-19 Data Suite. The platform identified and analyzed 836 disease signatures in two cohorts associated with increased risk of COVID-19 hospitalization. Cohort 1 was formed of cases hospitalized with COVID-19 and a set of controls who developed mild symptoms. Cohort 2 included Cohort 1 individuals for whom additional laboratory test data was available. We found several disease signatures where lower levels of lipids were found co-occurring with lower levels of serum calcium and leukocytes. Many of the low lipid signatures were independent of statin use and 50% of cases with hypocalcemia signatures were reported with vitamin D deficiency. These signatures may be attributed to similar mechanisms linking calcium and lipid signaling where changes in cellular lipid levels during inflammation and infection affect calcium signaling in host cells. This study and our previous genomics analysis demonstrate that combinatorial analysis can identify disease signatures associated with the risk of developing severe COVID-19 separately from genomic or clinical data in different populations. Both studies suggest associations between calcium and lipid signalling in severe COVID-19.
The real-time detection of emerging SARS-CoV-2 variants is critical to manage patients appropriately, and monitor and assess their epidemiological and clinical features. Sequencing is not a feasible comprehensive detection strategy considering the very large number of SARS-CoV-2 cases in our current setting. SARS-CoV-2 variants currently of greatest concern carry the N501Y substitution within the spike receptor binding domain. They have become predominant in England (20I/501Y.V1) and were detected in South Africa (20H/501Y.V2), Brazil and dozens of other countries worldwide. The 20I/501Y.V1 variant has started to spread worldwide including in France. It has been reported as 50-74% more transmissible than preexisting strains, suspected to evade anti-spike antibodies, and it caused a reinfection. We have implemented an in-house one-step real-time reverse transcription-PCR (qPCR) assay that specifically detects SARS-CoV-2 N501Y. It was found reliable to detect specifically the N501Y substitution and preliminarily allowed estimating 20I/501Y.V1 variant prevalence to 4% among our current SARS-CoV-2 diagnoses since January.
Background: There is discussion evolving around the emergence of different phenotypes of Covid-19-associated thromboembolic disease, i.e. acute pulmonary embolism vs pulmonary thrombosis and different phenotypes of in situ thrombosis. With this study, we wish to provide hospitalization, treatment and in-hospital outcome data for pulmonary embolism during the 2020 Covid-19 pandemic and a corresponding 2016-2019 control period. Methods: We performed a retrospective analysis of claims data of Helios hospitals in Germany. Consecutive cases with a hospital admission between January 1 and December 15, 2020 and pulmonary embolism as primary discharge diagnosis were analyzed and compared to a corresponding period covering the same weeks in 2016-2019. Results: As previously reported for other emergent medical conditions, there was a hospitalization deficit coinciding with the 1st pandemic wave. Beginning with the 12-week interval May 6 - July 28, there was a stable surplus of hospital admissions in 2020. During this surplus period (May 6 - December 15, 2020), there were 2,449 hospitalizations including 45 PCR-confirmed Covid-19 cases (1.8%) as opposed to 8,717 in 2016-2019 (IRR 1.12, 95% CI 1.07-1.18, P<0.01). When excluding Covid-19 cases IRR was 1.10 (95% CI 1.05-1.15, P<0.01). While overall comorbidities expressed as weighted AHRQ Elixhauser Comorbidity Index (14.1+/-10.1 vs. 13.9+/-10.3, P=0.28), the presence of thrombosis (46.1 vs 45.4%, P=0.55) and surgery (3.8 vs. 4.3%, P=0.33) were comparable, coagulopathy (3.3 vs 4.5%, P=0.01) and metastatic cancer (3.0 vs 4.0%, P=0.03) as contributing factors were less frequently observed during the 2020 surplus. Interventional treatments (thrombolytic therapy, thrombectomy or inferior vena cava filter placement) were less frequently used (4.7 vs 6.6%, OR 0.72, 95% CI 0.58-0.89, P< 0.01). Similarly, intensive care (35.1 vs 38.8%, OR 0.83, 95% CI 0.75-0.92, P< 0.01) and mechanical ventilation utilization (7.2 vs 8.1%, OR 0.88, 95% CI 0.74-1.04, P=0.14) as well as in-hospital-mortality rates (7.8 vs 9.8%, OR 0.76, 95% CI 0.64-0.90, P< 0.01) were lower in 2020 compared with 2016-2019. This was associated with a shorter length of hospital stay (6.4+/-5.4 vs. 7.2+/-5.7 days, P< 0.01) during the 2020 surplus period. Conclusions: Only a minority of cases were associated with PCR-confirmed Covid-19 but this does not rule out preceding or undetected SARS-CoV-2 infection. Although there is a shift towards milder disease course, the increased incidence of hospitalizations for pulmonary embolism requires immediate attention, close surveillance and further studies.
The COVID-19 poses a disproportionate threat to nursing home residents. Although recent studies suggested the effectiveness of state social distancing measures in the United States on curbing COVID-19 morbidity and mortality among the general population, there is lack of evidence as to how these state orders may have affected nursing home patients or what potential negative health consequences they may have had. In this longitudinal study, we evaluated changes in state strength of social distancing restrictions from June to August of 2020, and their associations with the weekly numbers of new COVID-19 cases, new COVID-19 deaths, and new non-COVID-19 deaths in nursing homes of the US. We found that stronger state social distancing measures were associated with improved COVID-19 outcomes (case and death rates), reduced across-facility disparities in COVID-19 outcomes, but more deaths due to non-COVID-19 reasons among nursing home residents.
Background: While there are numerous reports that describe emergency care during the early Covid-19 pandemic, there is scarcity of data for later stages. This study analyzes hospitalization rates for 37 emergency-sensitive conditions in the largest German-wide hospital network during different pandemic phases. Methods: Using claims data of 80 hospitals, consecutive cases between January 1 and November 17, 2020 were analyzed and compared to a corresponding period in 2019. Incidence-rate ratios (IRR) comparing the both periods were calculated using Poisson regression to model the number of hospitalizations per day. Results: There was a hospitalization deficit between March 12 and June 13, 2020 (coinciding with the 1st pandemic wave) with 32,807 hospitalizations as opposed to 39,379 in 2019 (IRR 0.83, 95% CI 0.82-0.85, P<0.01). During the following period (June 14 to November 17, 2020, including the start of 2nd wave), hospitalizations were reduced from 63,799 in 2019 to 59,910 in 2020, but this reduction was not that pronounced (IRR 0.94, 95% CI 0.93-0.95, P<0.01). There was an increase in hospitalizations for acute myocardial infarction, aortic aneurism/dissection and pulmonary embolism after the 1st wave during which hospitalizations had been reduced for those conditions. In contrast, hospitalizations for sepsis, pneumonia, obstructive pulmonary disease, and intracranial injuries were reduced during the entire pandemic. Conclusions: There was an overall reduction of hospitalizations for emergency-sensitive conditions in Germany during the Covid-19 pandemic with heterogeneous effects on different disease categories. The increase of hospitalizations for acute myocardial infarction, aortic aneurism/dissection and pulmonary embolism is an alarming signal that requires attention and further studies.
SARS-CoV-2 seroprevalence in an antenatal population in Kingston, Jamaica was assessed for September-November 2020 in a repeated cross-sectional study using the Abbott Architect SARS-CoV-2 IgG assay. After adjusting for test performance, seroprevalence was 6.9% for September, 16.9% for October, and 24.0% for November. Of the 37 pregnant women testing SARS-CoV-2 IgG positive, only 3 were symptomatic. One symptomatic woman testing SARS-CoV-2 IgG positive had multiple co-morbidities and succumbed to COVID-19 pneumonia. Up to January 31, 2021, 8 women identified as SARS-CoV-2 IgG positive delivered, all without complications. Comparison of test adjusted seroprevalence data with cumulative PCR-confirmed COVID-19 cases within the Kingston Metropolitan Area indicated that as many as 44.4 times more people were infected with SARS-CoV-2 than identified with PCR testing. These findings provide the first evidence for the extent of SARS-CoV-2 infections in Jamaica and will inform future SARS-CoV-2 testing strategies.
The vaccination rollout of the COVID-19 in Israel has been highly successful compared to all other countries. By the end of January, a third of the population has already been administered at least one dose of the BNT162b2 vaccine. Efforts to estimate the true real-world effectiveness of the vaccine have been hampered by disease dynamics and social-economic discrepancies. Here, using counts of positive and hospitalized cases of vaccinated individuals, we provide sensitive estimations of the vaccine effectiveness by correcting to daily case incidence. We find high effectiveness of 66-85% in reducing SARS-CoV-2 positive cases and over 90% in reducing severe hospitalizations. As more granular data will be available more it will be possible to extract more exact estimates; however, there is little doubt that the vaccine is highly effective in reducing cases, hospitalizations and deaths.
In order to curb the rapid transmission of SARS-CoV-2, nation-wide lockdowns were implemented as a preliminary measure. Since most countries enforced travel-bans during end of March 2020, the country-specific patterns should be discernible in the subsequent months. We identified frequently mutated non-synonymous mutations in 2,15,000 SARS-CoV-2 sequences during pre and post-travel-ban periods in 35 countries. We further investigated the mutational profile on a bi-monthly basis and traced the progress over the time. Several new mutations have emerged post-travel-ban and on the rise in specific countries, chief among them being A222V and S477N in Spike, and A220V in Nucleocapsid protein. Consequently, we examined the Spike protein epitopes to inspect whether any of these country-specific mutations overlapped with these epitopes. Several mutations were found to be contained within one or more epitopes, including the highly mutated residues of Spike protein, advocating the requirement of active monitoring of vaccine efficacies in respective countries.
New York City (NYC) emerged as a coronavirus disease 2019 (COVID-19) epicenter in March 2020, but there is limited information regarding potentially unrecognized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections before the first reported case. We utilized a sample pooling strategy to screen for SARS-CoV-2 RNA in de-identified, respiratory pathogen-negative nasopharyngeal specimens from 3,040 patients across our NYC health system who were evaluated for respiratory symptoms or influenza-like illness during the first 10 weeks of 2020. We obtained complete SARS-CoV-2 genome sequences from samples collected between late February and early March. Additionally, we detected SARS-CoV-2 RNA in pooled specimens collected in the week ending 25 January 2020, indicating that SARS-CoV-2 caused sporadic infections in NYC a full month before the first officially documented case.

Identification of ebselen and its analogues as potent covalent inhibitors of papain-like protease from SARS-CoV-2 - An efficient treatment against a COVID-19 disease, caused by the novel coronavirus SARS-CoV-2 (CoV2), remains a challenge. The papain-like protease (PL^(pro)) from the human coronavirus is a protease that plays a critical role in virus replication. Moreover, CoV2 uses this enzyme to modulate the host’s immune system to its own benefit. Therefore, it represents a highly promising target for the development of antiviral drugs. We used Approximate Bayesian Computation tools, molecular modelling and…

The antiviral effects could be detected in both human and…
Leflunomide an immunomodulator with antineoplastic and antiviral potentials but drug-induced liver injury: A comprehensive review - Leflunomide (LF) represents the prototype member of dihydroorotate dehydrogenase (DHODH) enzyme inhibitors. DHODH is a mitochondrial inner membrane enzyme responsible for catalytic conversion of dihydroorotate into orotate, a rate-limiting step in the de novo synthesis of the pyrimidine nucleotides. LF produces cellular depletion of pyrimidine nucleotides required for cell growth and proliferation. Based on the affected cells the outcome can be attainable as immunosuppression, antiproliferative,…

Development and evaluation of inhalable composite niclosamide-lysozyme particles: A broad-spectrum, patient-adaptable treatment for coronavirus infections and sequalae - Niclosamide (NIC) has demonstrated promising in vitro antiviral efficacy against SARS-CoV-2, the causative agent of the COVID-19 pandemic. Though NIC is already FDA-approved, administration of the currently available oral formulation results in systemic drug levels that are too low for the inhibition of SARS-CoV-2. We hypothesized that the co-formulation of NIC with an endogenous protein, human lysozyme (hLYS), could enable the direct aerosol delivery of the drug to the respiratory tract as an…
Multi-clonal SARS-CoV-2 neutralization by antibodies isolated from severe COVID-19 convalescent donors - The interactions between antibodies, SARS-CoV-2 and immune cells contribute to the pathogenesis of COVID-19 and protective immunity.

Challenges for Targeting SARS-CoV-2 Proteases as a Therapeutic Strategy for COVID-19 - Two proteases produced by the SARS-CoV-2 virus, the main protease and papain-like protease, are essential for viral replication and have become the focus of drug development programs for treatment of COVID-19. We screened a highly focused library of compounds containing covalent warheads designed to target cysteine proteases to identify new lead scaffolds for both M^(pro) and PL^(pro) proteases. These efforts identified a small number of hits for the M^(pro) protease and no viable hits for the…
Amino acid sensing pathway: A major check point in the pathogenesis of obesity and COVID-19 - Obesity and obesogenic comorbidities have been associated with COVID-19 susceptibility and mortality. However, the mechanism of such correlations requires an in-depth understanding. Overnutrition/excess serum amino acid profile during obesity has been linked with inflammation and reprogramming of translational machinery through hyperactivation of amino acid sensor mammalian target of rapamycin (mTOR), which is exploited by SARS-CoV-2 for its replication. Conversely, we have shown that the…
