Influence of HIV infection on clinical course of the new coronavirus infection (COVID-19)

BACKGROUND: Human immunodeficiency virus (HIV)-associated severe immunosuppression, high viral load, non-HIV-related comorbidities and conditions, and lack of antiretroviral therapy may exacerbate the clinical course of coronavirus disease 2019 (COVID-19).

AIM: To assess the effect of HIV infection on the clinical course of COVID-19, disease severity, and its outcomes.

MATERIALS AND METHODS: Medical records of 35,328 patients who had COVID-19 in 2020 were analyzed, including 46 cases of COVID-19 in individuals with HIV infection. Clinical variants and COVID-19 severity, frequency of COVID-19 detection by polymerase chain reaction, CD4 lymphocyte count, viral load in individuals with HIV infection, and mortality rates were assessed.

RESULTS: In 76% of patients with coinfection, signs of HIV infection progression, opportunistic infections, and concomitant diseases were noted. Moreover, 52.2% of the patients analyzed were users of psychoactive substances. Among patients with HIV and COVID-19, men predominated in groups aged >30 years, whereas among the HIV-negative population, women were predominant in groups aged >18 years. The proportion of severe COVID-19 in individuals with HIV infection (47.8%) exceeds that in the group without HIV (12.3%). The mortality rate from COVID-19 in the HIV-infected group was more than seven times higher than that in the HIV-negative group (t=1.81; p=0.01).

CONCLUSIONS: In the HIV-infected group, extremely severe COVID-19 was more common. Weakness, cough, shortness of breath, and myalgia were significantly more common in the HIV-infected group. Moreover, the HIV-infected group with an undetectable viral load and adequate CD4 lymphocyte count in the blood was exposed to the same risks of the disease and its progression as the HIV-negative group.
