High viral suppression and low attrition in healthy HIV-infected patients initiated on ART with CD4 above 500 cells/µL in a program setting in Uganda

Background The World Health Organization recommends antiretroviral therapy (ART) for all HIV-infected patients at all CD4 counts. However, there are concerns that asymptomatic patients may have poorer viral suppression and high attrition. Objectives We sought to determine attrition and viral suppression among healthy HIV-infected patients initiated on ART in program settings. Methods This cross-sectional study enrolled ART-experienced patients attending two PEPFAR-supported, high-volume clinics in Kampala, Uganda. Eligible patients were >18 years and had completed at least six months on ART. Participants were interviewed on socio-demographics, ART history and plasma viral load (VL) determined using Abbott Real-time. Predictors of viral suppression (<75 copies/ml) were determined using multivariate logistic regression. Results Overall, 267 participants were screened, 228 were eligible and 203 (89%) retained in care (visit within 90 days). Of the 203 participants, 115 (56.7%) were key-populations. Viral suppression was achieved in 173 patients (85%; 95% CI, 80.3%–90.1%). The factors associated with viral suppression were prior VL tests (AOR 6.98; p-value <0.001) and receiving care from a general clinic (AOR 5.41; p=0.009). Conclusion Asymptomatic patients initiated on ART with high baseline CD4 counts, achieve high viral suppression with low risk of attrition. VL monitoring and clinic type are associated with viral suppression.
