Pernio-like skin lesions associated with COVID-19: A case series of 318 patients from 8 countries

Esther E. Freeman, Devon E. McMahon, Jules B. Lipoff et al.

An international dermatology registry was circulated to health care providers worldwide through the American Academy of Dermatology, International League of Dermatologic Societies, and other organizations. The authors documented 505 patients with dermatologic manifestations associated with COVID-19, including 318 (63%) with pernio-like lesions. Patients with pernio-like lesions were generally young and healthy, with relatively mild COVID-19. The authors conclude that pernio-like skin changes of the feet and hands, without another explanation, may suggest COVID-19 infection and should prompt confirmatory testing.

The Search for a COVID-19 Animal Model

Seema S. Lakdawala, Vineet D. Menachery

Translating data from a single animal model to the varied disease outcomes in humans is not only challenging, but potentially misleading. Studies examining the efficacy of vaccines and antiviral drugs traditionally use models of severe disease, which may not mimic the common pathology in the majority of COVID-19 patients and could limit understanding of other important questions, including infection dynamics and transmission. Here, the authors compare currently available animal models for SARS-CoV-2 infection and COVID-19 in search for the best animal model to study COVID-19.

The amount of cytokine-release defines different shades of Sars-Cov2 infection

S Bindolli, M Felicetti, P Sfriso et al.

This minireview contributes to providing a point of view regarding the immunological mechanisms beyond COVID-19 infection. Base on current evidence, the authors suggest to classify patients into three main clinical phenotypes according to the amount and pattern of cytokines released during the infection. By evaluating the degree of immunological activation provoked by SARS-CoV2, this article contributes in understanding better how to choose the correct clinical approach with immuno-modulatory therapies which, in turn, may help in curbing the hyper-inflammatory condition of patients affected.

Any unique image biomarkers associated with COVID-19?

Pu, J., Leader, J., Bandos, A. et al.

The authors compared CT scans of COVID-19 and Non-COVID19 community acquired pneumonia patients to define the uniqueness of chest CT infiltrative features associated with COVID-19 image characteristics as potential diagnostic biomarkers. They found that unique image features or patterns may not exist for reliably distinguishing all COVID-19 from CAP; however, there may be imaging markers that can identify a sizeable subset of non-COVID-19 cases.

Remdesivir for 5 or 10 Days in Patients with Severe Covid-19

Jason D. Goldman, David C.B. Lye,David S. Hui, Kristen M. Marks et al.

The authors conducted a randomized, open-label, phase 3 trial involving hospitalized patients with confirmed severe SARS-CoV-2 infection. 397 patients were randomly assigned in a 1:1 ratio to receive intravenous remdesivir for either 5 days or 10 days. All patients received 200 mg of remdesivir on day 1 and 100 mg once daily on subsequent days. In patients with severe Covid-19 not requiring mechanical ventilation, the trial did not show a significant difference between a 5-day course and a 10-day course of remdesivir. With no placebo control, however, the magnitude of benefit cannot be determined.

Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period

Stephen M. Kissler, Christine Tedijanto, Edward Goldstein, Yonatan H. Grad, Marc Lipsitch

Kissler et al. used existing data to build a deterministic model of multiyear interactions between existing coronaviruses, with a focus on the United States, and used this to project the potential epidemic dynamics and pressures on critical care capacity over the next 5 years. The long-term dynamics of SARS-CoV-2 strongly depends on immune responses and immune cross-reactions between the coronaviruses, as well as the timing of introduction of the new virus into a population. One scenario is that a resurgence in SARS-CoV-2 could occur as far into the future as 2025.

Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: a multinational registry analysis

Prof Mandeep R Mehra, Sapan S Desai, Prof Frank Ruschitzka, Amit N Patel

The authors performed a multinational registry analysis of the use of hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19. The registry comprised data from 671 hospitals in six continents. They were unable to confirm a benefit of hydroxychloroquine or chloroquine, when used alone or with a macrolide, on in-hospital outcomes for COVID-19. Each of these drug regimens was associated with decreased in-hospital survival and an increased frequency of ventricular arrhythmias when used for treatment of COVID-19.

Predicting infectious SARS-CoV-2 from diagnostic samples 

Jared Bullard, Kerry Dust, Duane Funk, James E Strong, David Alexander et al.

An RT-PCR test for SARS-CoV2 detects RNA but not infectious virus, thus its ability to determine duration of infectivity of patients is limited. Infectivity is a critical determinant in informing public health guidelines/interventions. Here, the authors perform a retrospective cross-sectional study and took SARS-CoV-2 RT-PCR confirmed positive samples and determined their ability to infect Vero cell lines. They found that cell infectivity was only observed for samples with PCR Cycle time < 24 and from patients with < 8 days from symptom onset.

A simple algorithm helps early identification of SARS-CoV-2 infection patients with severe progression tendency

Qiang Li, Jianliang Zhang, Yun Ling et al.

The authors performed univariable and multivariable analysis to identify the independent predictors of COVID-19 progression. The prediction model was established in a retrospective training set of 322 COVID-19 patients and was re- evaluated in a prospective validation set of 317 COVID-19 patients. They found that The age-LDH-CD4 model is a simple algorithm for early identifying patients with severe progression tendency following SARS-CoV-2 infection, and warrants further validation.

Immunogenicity of a DNA vaccine candidate for COVID-19

Smith, T.R.F., Patel, A., Ramos, S. et al.

In this paper, the authors discuss their findings after generating a synthetic DNA-based vaccine candidate targeting SARS-CoV-2 S protein. The engineered construct, INO-4800, results in robust expression of the S protein in vitro. Following immunization of mice and guinea pigs with INO-4800, they measured antigen-specific T cell responses, functional antibodies which neutralize the SARS-CoV-2 infection and block Spike protein binding to the ACE2 receptor, and biodistribution of SARS-CoV-2 targeting antibodies to the lungs. This preliminary dataset identifies INO-4800 as a potential COVID-19 vaccine candidate, supporting further translational study.

DNA vaccine protection against SARS-CoV-2 in rhesus macaques

Jingyou Yu, Lisa H. Tostanoski, Lauren Peter et al.

The authors developed a series of DNA vaccine candidates expressing different forms of the SARS-CoV-2 Spike (S) protein and evaluated them in 35 rhesus macaques.  They found that vaccinated animals developed humoral and cellular immune responses, including neutralizing antibody titers comparable to those found in convalescent humans and macaques infected with SARS-CoV-2. Following vaccination, all animals were challenged with SARS-CoV-2, and the authors found reductions in median viral loads in bronchoalveolar lavage and nasal mucosa samples from these macaques, as compared with sham controls. Vaccine-elicited neutralizing antibody titers correlated with protective efficacy, suggesting an immune correlate of protection. These data demonstrate vaccine protection against SARS-CoV-2 in nonhuman primates.

The COVID-19 Pandemic and the Incidence of Acute Myocardial Infarction

Matthew D. Solomon, Edward J. McNulty, Jamal S. Rana et al.

During the Covid-19 pandemic, reports have suggested a decrease in the number of patients presenting to hospitals because of emergency conditions such as acute myocardial infarction. The authors examined this issue using data from a large integrated health care delivery system with 21 medical centers and 255 clinics that provides comprehensive care for more than 4.4 million persons throughout Northern California. They found that the incidence of hospitalization for acute myocardial infarction declined after March 4, 2020, during the Covid-19 pandemic, more than would be expected on the basis of typical seasonal variation alone.

Evidence for host-dependent RNA editing in the transcriptome of SARS-CoV-2

Salvatore Di Giorgio, Filippo Martignano, Maria Gabriella Torcia, Giorgio Mattiuz, Silvestro G. Conticello

The authors analyze RNA sequences from bronchoalveolar lavage fluids derived from COVID-19 infected patients. They identify nucleotide changes that may be signatures of RNA editing: Adenosine-to-Inosine changes from ADAR deaminases and Cytosine-to-Uracil changes from APOBEC ones. Their results suggest that both APOBECs and ADARs are involved in Coronavirus genome editing, a process that may shape the fate of both virus and patient.

Cross-neutralization of SARS-CoV-2 by a human monoclonal SARS-CoV antibody

Pinto, D., Park, Y., Beltramello, M. et al.

Vaccine and therapeutic discovery efforts are paramount to curb the pandemic spread of this SARS-CoV2 virus. The SARS-CoV-2 spike (S) glycoprotein promotes entry into host cells and is the main target of neutralizing antibodies. Here the authors describe multiple monoclonal antibodies targeting SARS-CoV-2 S identified from memory B cells of an individual who was infected with SARS-CoV in 2003. They explain the potential of using S309- and S309-containing antibody cocktails for prophylaxis in individuals at high risk of exposure or as a post-exposure therapy to limit or treat severe disease.

COVID-19 in people living with human immunodeficiency virus: a case series of 33 patients

Georg Harter, Christoph D. Spinner, Julia Roider et al.

This case series of 33 PLWH patients with COVID-19 reveals symptoms and outcome in this special population. A retrospective analysis of anonymized data was carried out including age, gender, HIV-associated parameters, symptoms, and outcome. This preliminary case series does not support excess morbidity and mortality among symptomatic COVID-19 PLWH and with viral suppression on ART. SARS-CoV-2 infections may occur during boosted darunavir-based and/or on tenofovir-containing ART.
