This study compared the immunological responses to commonly used antiretroviral therapy regimens among people with advanced HIV in the USA, and assessed virological outcomes and regimen persistence. The results showed that initiating ART with the B/F/TAF regimen was associated with faster CD4 cell count recovery and favorable virological outcomes compared with other regimens.
Objectives Our objective was to compare the immunological responses to commonly used antiretroviral therapy (ART) regimens among people with advanced HIV in the USA and to assess virological outcomes and regimen persistence.Methods This study included ART-naive adults with advanced HIV infection (CD4 cell count < 200 cells/mu L) initiating ART with bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF), boosted darunavir (bDRV), dolutegravir (DTG), or elvitegravir (EVG/c)-containing regimens between 1 January 2018 and 31 December 2020 in the Observational Pharmaco-Epidemiology Research and Analysis (OPERA) cohort. Cox proportional hazards models and linear mixed models with random intercept were fit with inverse probability of treatment weighting.Results Overall, 1349 people with advanced HIV (816 B/F/TAF, 253 DTG, 146 EVG/c, 134 bDRV) were followed for a median of 22 months. Compared with B/F/TAF, a lower likelihood of achieving a CD4 cell count >= 200 cells/mu L was observed with bDRV (hazard ratio [HR] 0.76; 95% confidence interval [CI] 0.60-0.96), DTG (HR 0.82; 95% CI 0.69-0.98), and EVG/c (HR 0.73; 95% CI 0.57-0.93). All groups had a similar pattern of CD4:CD8 ratio changes: a rapid increase in the first 6 months (ranging from +0.15 to +0.16 units), followed by a slower increase thereafter. Only 40 individuals (4%) achieved CD4:CD8 ratio normalization (>= 1). B/F/TAF was associated with a faster time to virological suppression (viral load < 200 copies/mL) and a slower time to discontinuation compared with other regimens.Conclusions Among people with advanced HIV infection, B/F/TAF initiation was associated with faster CD4 cell count recovery and favourable virological outcomes compared with bDRV-, DTG-, and EVG/c-based regimens, although no difference was observed in CD4:CD8 ratio changes over time across regimens.
