SARS-CoV-2 infection clinical picture and outcomes in adults living with HIV: a cohort analysis.

Existing evidence about HIV and SARS-CoV-2 co-infection has, so far, yield conflicting results. Methods: This is a cohort, single center, clinical study aimed at identifying possible characteristics of PLWH that could correlate with the risk of acquiring SARS-CoV-2 and would influence the outcome. 155 cases of SARS-CoV-2 infection were compared with 307 PLWH who tested negative. No variable was associated with an increased risk of infection. SARS-CoV-2 PLWH were completely asymptomatic in 20.6% of cases. Factors associated with severe COVID-19 were age (P=0.001), diabetes (P=0.009) hypertension (P=0.004), cardiovascular disease (P=0.001) or an increasing number of chronic co-morbidities (P=0.002); only the first two variables retained statistical significance in a multivariable model. Only older age and a lower CD4 count were statistically associated with death in the multivariate model. Sixteen PLWH not included in the analysis were infected by SARS-Cov-2 after vaccination. In 4 cases the infection was completely asymptomatic, while in the remaining 12 cases the infection was mild and resembled a flu-like syndrome. Conclusions: No baseline characteristic defines patients at greater risk of SARS-CoV-2 infection. Older age and the presence of multi-comorbidities are risk factors for a severe clinical course. Lower CD4 counts correlate with a fatal outcome.
