Summary The coronavirus disease 2019 (COVID‐19) pandemic is a rapidly evolving global emergency that continues to strain healthcare systems. Emerging research describes a plethora of patient factors—including demographic, clinical, immunologic, hematological, biochemical, and radiographic findings—that may be of utility to clinicians to predict COVID‐19 severity and mortality. We present a synthesis of the current literature pertaining to factors predictive of COVID‐19 clinical course and outcomes. Findings associated with increased disease severity and/or mortality include age > 55 years, multiple pre‐existing comorbidities, hypoxia, specific computed tomography findings indicative of extensive lung involvement, diverse laboratory test abnormalities, and biomarkers of end‐organ dysfunction. Hypothesis‐driven research is critical to identify the key evidence‐based prognostic factors that will inform the design of intervention studies to improve the outcomes of patients with COVID‐19 and to appropriately allocate scarce resources.

Introduction Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2) has infected >6 million people worldwide since December 2019. Global reports of HIV/SARS‐CoV‐2 coinfection are limited. To better understand the impact of the coronavirus disease 2019 (COVID‐19) pandemic on persons with HIV and improve their care, we present an outpatient and inpatient clinical experience of HIV/SARS‐CoV‐2 coinfection from Rhode Island, US. Methods We describe outpatient and inpatient preparedness for the COVID‐19 pandemic, and present a case series of all known patients with HIV/SARS‐CoV‐2 coinfection at The Miriam Hospital and Rhode Island Hospital, and The Miriam Hospital Infectious Diseases and Immunology Center, in Providence, Rhode Island, US. Results and discussion The Infectious Diseases and Immunology Center rapidly prepared for outpatient and inpatient care of persons with HIV and SARS‐CoV‐2. Between 30 March and 20 May 2020, 27 patients with HIV were diagnosed with SARS‐CoV‐2. Twenty were male, six female and one transgender female; average age was 49 years; 13/27 were Hispanic and 6/27 were African American. All had HIV viral load <200 copies/mL and were on antiretroviral therapy with CD4 count range 87 to 1441 cells/µL. Twenty‐six of the 27 had common COVID‐19 symptoms for one to twenty‐eight days and most had other co‐morbidities and/or risk factors. Nine of the 27 were hospitalized for one to thirteen days; of those, three lived in a nursing home, six received remdesivir through a clinical trial or emergency use authorization and tolerated it well; eight recovered and one died. Overall, 17% of known Center people had HIV/SARS‐CoV‐2 coinfection, whereas the comparable state‐wide prevalence was 9%. Conclusions We highlight challenges of outpatient and inpatient HIV care in the setting of the COVID‐19 pandemic and present the largest detailed case series to date from the United States on HIV/SARS‐CoV‐2 coinfection, adding to limited global reports. The aggregated clinical findings suggest that the clinical presentation and outcomes of COVID‐19 appear consistent with those without HIV. Whether SARS‐CoV‐2 infection is more frequent among persons with HIV remains to be determined. More data are needed as we develop our understanding of how HIV and antiretroviral therapy are affected by or have an impact on this pandemic.

Background The US Food and Drug Administration issued an Emergency Use Authorization for remdesivir use in patients with severe COVID-19. Methods We utilized data from two quaternary, acute care hospitals. The outcomes of interest were the impact of remdesivir on in-hospital death by day 28 as well as time to recovery, clinical improvement, and discharge. We utilized Cox proportional hazards models and stratified log-rank tests. Results 224 patients were included in the study. Median age was 59 years; 67.0% were male; 17/125 patients (13.6%) who received supportive care and 7/99 patients (7.1%) who received remdesivir died. The unadjusted risk for 28-day in-hospital death was lower for patients who received remdesivir compared to patients who received supportive care (HR 0.42; 95% CI: 0.16-1.08). Although this trend remained the same after adjusting for age, sex, race and oxygen requirements on admission (aHR 0.49; 95% CI: 0.19-1.28), as well as chronic comorbidities and use of corticosteroids (aHR 0.44; 95% CI: 0.16-1.23), it did not reach statistical significance. The use of remdesivir was not associated with an increased risk of acute kidney injury (AKI) and liver test abnormalities. Although not statistically significant, the rate ratios for time to recovery, clinical improvement, and discharge were higher in women and Black or African American patients. Conclusion Patients on remdesivir had lower, albeit not significant, all-cause in hospital mortality, and the use of remdesivir did not increase the risk for AKI. Promising signals from this study need to be confirmed by future placebo-controlled randomized clinical trials.
