Abstract
Background
This study examined the prevalence and factors associated with detectable viremia, as well as clinical outcomes among people with HIV (PWH) receiving antiretroviral therapy (ART) who initially achieved viral suppression in 2 southern states in Nigeria.
Methods
The retrospective cohort study used data from the electronic medical records of 96 comprehensive ART centers. PWH were followed up who achieved viral suppression (viral load [VL] ≤50 copies/mL) upon starting ART based on the first VL test. We examined the presence of detectable viremia in follow-up VL results, graded by the absolute VL count from the second and third consecutive VL tests as follows: transient viremia (second follow-up VL, 51–999 copies/mL; third, ≤50 copies/mL), persistent viremia (second follow-up VL, 51–999 copies/mL or ≥1000 copies/mL; third, >50 copies/mL), and virologic failure (second and third follow-up VL, >1000 copies/mL). We analyzed demographic and clinical factors associated with detectable viremia using logistic regression analysis on Stata 14.
Results
Overall, 15 050 PWH had achieved viral suppression following ART initiation (median age, 34 years; 71.3% female). On follow-up, 3101 (20.6%) had a viremic event: 11.6%, transient viremia; 8.8%, persistent viremia; 0.2%, virologic failure. Shorter duration of ART (P < .001), being 0 to 14 years of age (P < .001), and not being enrolled in a differentiated service delivery model (P < .001) were significantly associated with detectable viremia.
Conclusions
Our study shows that people who initially attain vial suppression upon starting ART remain at risk of detectable viremia.
