[Characteristics of Low-Level Persistent viraemias in HIV-1 Patients Treated with Second-Line ARVs at the Sourô Sanou Teaching Hospital of Bobo-Dioulasso (Burkina Faso)].

We describe the characteristics of patients infected with HIV-1 as second-line antiretroviral therapy, with persisting low-level viremia. This was a descriptive retrospective study, conducted from January 1, 2010 to December 31, 2016, from the Cohort of the Infectious Diseases Department of Bobo-Dioulasso University Hospital. Patients infected with HIV-1, a second line of stable ARV treatment, with ≥95% compliance for at least 12 months, asymptomatic with CVp between 50 and 1000 copies/ml in two consecutive samplings at least 3 months apart. Out of 244 patients in second-line therapy, 79 met our inclusion criteria. The mean age of the patients was 42±10.2 years. Women (35.8 years) were younger than men (43.8 years) (p=0.001). Most were married (48.1%), 23.5% of whom were polygamous. The majority of patients (38/79) in the study had a CD4 count of <200 cells/ mm3. The median duration of ARV therapy since the beginning of the therapeutic history has been 4.8 (2.5-11 years). CVp greater than 10,000 copies/ml at the start of second-line therapy (p=0.003) and TDF+FTC + DRV + RTV combination (p=0.001) were associated with persistent low viremia. A genotypic resistance test is needed for these patients in order to better adapt the ARV treatment.
