Hepatic Steatosis and Weight Gain During the Coronavirus Disease 2019 Pandemic Among People With Human Immunodeficiency Virus: Impact of Therapy With Tenofovir Alafenamide

BACKGROUND: Lockdown due to the coronavirus disease 2019 (COVID-19) pandemic led to increases in weight in part of the population. Weight gain leads to hepatic steatosis (HS). Antiretroviral treatment could also influence HS in people with human immunodeficiency virus (PWH). The impact of lockdown on HS in PWH is unknown. The aim of this study was to analyze the changes in HS, as measured by the controlled attenuation parameter (CAP), during the COVID-19 pandemic in PWH. METHODS: This was a cohort study that included PWH who attended a tertiary care center in southern Spain from January 2018 to December 2021. The CAP was evaluated by transient elastography. Only those who had a valid CAP before and after March 2020 were included. HS was defined as CAP ≥248 dB/m. RESULTS: Six hundred eighty PWH were attended and 488 (71.8%) were included. Two hundred and fourteen (43.9%) had HS at baseline and 239 (49%) at the end of the follow-up (P = .036). The median change in CAP among PWH taking tenofovir alafenamide (TAF) was 8.5 (interquartile range [IQR], −24 to 46.3) dB/m versus −4 (IQR, −35 to 27) dB/m among PWH receiving TAF-free regimens (P = .003). After multivariate analysis, adjusted by sex and age, weight gain (adjusted odds ratio [AOR], 1.09 [95% confidence interval {CI}, 1.05–1.14]; P < .001), TAF therapy (AOR, 1.59 [95% CI, 1.07–2.35]; P = .021), plasma triglycerides (AOR, 1.01 [95% CI, 1–1.01]; P < .001), and fasting blood glucose (AOR, 1.01 [95% CI, 1–1.02]; P = .027) were associated with HS at the end of follow-up. CONCLUSIONS: The frequency of HS increased during the COVID-19 pandemic among PWH. TAF is associated with HS development, regardless of metabolic factors.
