Abstract

Introduction: antiretroviral therapy enables the suppression of the plasma viral load and the restoration of immune responses. Therapeutic failures are still observed in patients living with HIV despite the considerable benefits of antiretroviral therapy. This study aimed to describe the long-term evolution of immunological and virological parameters in patients undergoing treatments for HIV-1 at the Day Hospital of Bobo-Dioulasso in Burkina Faso.

Methods: a retrospective descriptive and analytical study covering 10 years from 2009 was conducted at the Sourô Sanou University Hospital Center (CHUSS) in Bobo-Dioulasso. HIV-1-positive patients with at least two viral load measurements and two CD4 T cell counts were included in this study. Excel 2019 and RStudio were used to analyze the data.

Results: a total of 265 patients were included in this study. The mean age of the patients was 48 ± 8.98 years and women accounted for 77.7% of the study population. A considerable decrease in the number of patients with TCD4 lymphocytes below 200 cells/μl from year 2 of treatment and a progressive increase in those with TCD4 lymphocytes above 500 cells/μl were observed in the study. Regarding the evolution of viral load, an increase in the proportions of patients with an undetectable viral load and a decrease in those with a viral load greater than 1000 copies/ml were noticed in years 2, 5, 6, and 8 of the follow-up. However, a decrease in the proportions of patients with undetectable viral load and an increase in those with viral load above 1000 copies/ml were observed in the years 4, 7, and 10 of follow-up.

Conclusion: this study highlighted the different trends of viral load and LTCD4 evolution over 10 years of antiretroviral treatment. It showed a good immunovirological response was shown at the beginning of antiretroviral therapy, and then, a poor evolution of these markers at certain periods during the follow-up of HIV-positive patients.
