Higher Rates of SARS-CoV-2 Seropositivity in the USA
The number of reporting cases of COVID-19 infection tends to underestimate the true prevalence of infection as only the more severe cases (e.g.,acute respiratory syndrome) get tested or go to the hospital. JAMA Internal Medicine reports that a cross-sectional seroprevalence study from the U.S. shows that COVID-19 is underreported and that actual infection rates can be 6 to 24 times more prevalent than currently reported infections due to SARS-CoV-2.

A recent study from the Netherlands has shown that patients with severe COVID-19-associated cytokine storm syndrome (CSS) with high dose steroids and tocilizumab had a faster recovery, less need for invasive mechanical ventilation and fewer deaths when compared to CSS patients receiving supportive care only.
They studed COVID-19 patients with CSS, defined as rapid respiratory deterioration plus at least two of the following biomarkers: a) C-reactive protein >100mg/L; b) ferritin >900 µg/L; or c) D-dimer >1500 µg/L.

RECOVERY Trial: Dexamethasone in COVID-19
Inflammatory events following infection with SARS-CoV-2 can often worsen the morbid or mortal outcomes with COVID, yet it has been unclear if glucocorticoids may modulate inflammation-mediated damage and lung injury. The RECOVERY trial reports that dexamethasone (DEX) use lowered 28-day mortality among COVID-19 patients requiring respiratory support.
The RECOVERY trial was performed in the UK and enrolled hospitalized COVID-19 patients who were randomly assigned patients to usual care alone or the addition of oral or intravenous dexamethasone (at a dose of 6 mg once daily) for up to 10 days. The primary outcome was 28-day mortality.

Characteristics Underlying Mortal COVID-19 Outcomes
From January 1, 2020–May 18, 2020, approximately 1.3 million cases of coronavirus disease 2019 (COVID-19) and 83,000 COVID-19–associated deaths were reported in the United States.

Anti-Rheumatic Therapies for COVID-19 Infection
Since the onset of the COVID-19 pandemic numerous anti-rheumatic therapies have been proposed as being potentially beneficial. The mechanistic effects of these agents, either presumed antiviral, anti-inflammatory and anti-thrombotic effects, may benefit mitigate the damage seen with COVID-19 infection.
This review will examine the potential benefits and existing evidence for treating suspected or proven COVID-19 infection with antimalarials, inhibitors of interleukin-6 (IL-6) or interleukin-1 (IL-1) Janus kinase (JAK) inhibitors, TNF inhibitors or colchicine. There are many other antirheumatic and immunosuppressive therapies that are in clinical trials that will not be reviewed here including IVIG, rituximab, calcineurin inhibitors (sirolimus, etc.), apremilast, emapalumab (anti-IFN gamma), etc.
