- The impact of low levels of HIV RNA (low-level viremia; LLV) during combination antiretroviral therapy (cART) on clinical outcomes is unclear. We explored the associations between LLV and all-cause mortality, AIDS, and serious non-AIDS events (SNAE).We grouped individuals starting cART 1996-2017 (identified from the Swedish InfCare HIV register) as virologic suppression (VS; <50 copies/mL), LLV (repeated viral load 50-999 copies/mL), and non-suppressed viremia (NSV; ≥1000 copies/mL). Separately, LLV was subdivided into 50-199 and 200-999 copies/mL (reflecting different definitions of virologic failure). Proportional-hazard models (including sex, age, pre-ART CD4 count and viral load, country of birth, injection drug use, treatment experience and interruptions, and an interaction term between viremia and time) were fitted for the study outcomes.6,956 participants were followed for a median of 5.7 years. At the end of follow-up, 60% were categorized as VS, 9% as LLV, and 31% as NSV. Compared with VS, LLV was associated with increased mortality (adjusted hazard ratio [aHR] 2.2, 95% confidence interval [CI] 1.3-3.6). This association was also observed for LLV 50-199 copies/mL (aHR 2.2, 95% CI 1.3-3.8), but was not statistically significant for LLV 200-999 copies/mL (aHR 2.1, 95% CI 0.96-4.7). LLV 50-999 copies/mL was not linked to increased risk of AIDS or SNAE, but in subanalysis, LLV 200-999 copies/mL was associated with SNAE (aHR 2.0, 95% CI 1.2-3.6).In this population-based cohort, LLV during cART was associated with adverse clinical outcomes.
