REGN-COV2, a Neutralizing Antibody Cocktail, in Outpatients with Covid-19

D. M. Weinreich et al.

Summary: Recent data indicate that complications and death from Covid-19 may be related to high viral loads. In this trial involving nonhospitalized patients, a cocktail of two neutralizing monoclonal antibodies (REGN-COV2) reduced viral load, with a greater effect in patients with no immune response or high viral load at baseline. Safety outcomes were similar between REGN-COV2 dose groups and the placebo group.

The prognostic value of comorbidity for the severity of COVID-19: A systematic review and meta-analysis study

Mobina Fathi et al.

Summary: This study evaluated the clinical characteristics of COVID-19 patients and found that underlying diseases such as hypertension, diabetes, cardiovascular diseases, and chronic kidney disease may be risk factors for COVID-19 infection. Furthermore, the results suggest that elderly males with underlying diseases are more likely to have severe COVID-19.
