ABSTRACT
Background:
Human immunodeficiency virus low-level viremia (LLV) is associated with subsequent treatment failure at least with non nucleoside reverse transcriptase inhibitor (NNRTI)-containing antiretroviral therapy. Data on implications of LLV occurring under dolutegravir, which has largely replaced NNRTIs in Africa, are scarce, however.Methods:
We included adults with human immunodeficiency virus in Lesotho who had ≥2 viral loads (VLs) taken after ≥6 months of NNRTI- or dolutegravir-based antiretroviral therapy. Within VL pairs, we assessed the association of viral suppression (<50â copies/mL) and low- and high-range LLV (50-199 and 200-999â copies/mL, respectively) with virological failure (≥1000â copies/mL) using a mixed-effects regression model. Participants could contribute VLs to the NNRTI and the dolutegravir group.Results:
Among 18 550 participants, 12 216 (65.9%) were female and median age at first VL included was 41.2 years (interquartile range, 33.4-51.5). In both groups, compared with a suppressed VL, odds of subsequent virological failure were higher for low-range LLV (NNRTI adjusted odds ratio; 95% confidence interval 1.9; 1.4-2.4 and dolutegravir 2.1; 1.3-3.6) and high-range LLV (adjusted odds ratio; 95% confidence interval, 4.2; 3.1-5.7 and 4.4; 2.4-7.9).Conclusions:
In the dolutegravir era, LLV remains associated with virological failure, endorsing the need for close clinical and laboratory monitoring of those with a VL ≥50â copies/mL.
