Asymptomatic COVID-19 is common among the general population, but little has been reported on this phenomenon among people with HIV (PWH) globally. Here we present data on a representative subset of 2,464 REPRIEVE participants with blood collected for COVID-19 serology from May 2020 to February 2021.
REPRIEVE is an international primary atherosclerotic cardiovascular disease (ASCVD) prevention RCT of pitavastatin calcium vs. placebo among 7,770 PWH ages 40-75 on antiretroviral therapy (ART). Beginning in April 2020, targeted data on COVID-19 diagnosis and symptoms were collected as part of routine trial visits every 4 months, and blood was collected annually to assess SARS-CoV-2 serology. SARS-CoV-2 infection was defined as either presence of SARS-CoV-2 IgG or IgA RBD protein (anti-spike) antibodies or reporting of confirmed COVID-19 disease prior to the date of antibody sampling in the absence of prior COVID-19 vaccine receipt. We distinguished symptomatic from asymptomatic disease based on completed COVID-19 symptom questionnaire. Demographic, cardiometabolic, and HIV-specific data are described among those with symptomatic versus asymptomatic COVID-19 disease.
Participant characteristics (n=2464) included median age 53 years, 35% female sex, 47% Black or African American race, median CD4 count 649 c/mm3, and 97% with HIV VL <400 cp/mL. SARS-CoV-2 infection occurred in 318 persons (13%): 58 with clinical disease diagnosis and 260 with reactive Abs but no reported clinical disease. Of these persons, 304 completed symptom questionnaires: 120 (39%) reported at least 1 symptom of COVID-19 disease, but 184 (61%) reported no symptoms. PWH with asymptomatic infection were more likely to be from non-High Income Regions, of Black or African American race, and to be non-obese (Table). Median ASCVD risk score was <5% (low risk) for the two groups. Potential differences in symptomatic disease based on ART-regimen were noted, but no clinical differences between the groups for CD4 counts or HIV viral suppression were observed.
Asymptomatic SARS-CoV-2 infection is very common among ART-treated PWH globally. With Ab testing, we determined that 61% of COVID-19 infections were asymptomatic in the REPRIEVE cohort, similar to rates reported in the general population. HIV clinicians must remain vigilant about COVID-19 testing among PWH to assure that asymptomatic cases are identified.
