Future of HIV2 and HIV2 + 1 Infected Patients Treated with Antiretrovirals Followed at the Day Hospital HIV Care Unit from 2011 to 2015.

Introduction: HIV2 is endemic in West Africa. In Burkina Faso, its prevalence was estimated at 2%. The aim of this work was to evaluate the follow-up of patients and also to contribute to the availability of data. Methods: We involved 18 years or older. Infection was screened according to the national algorithm. A cross- sectional study from first June 2017 to 31 December 2017 was performed. For each patient, sociodemographic, clinical, biological, therapeutic and evolution data were collected and analyzed. Results: The proportion of patients infected with HIV2 (n  =  48; 1.7%) and HIV2  +  1 (n  =  67; 2.4%) was 4.3%. The sex rat mean age was 50.3  ±  8.5 years. The combination of 2INTI  +  LPV/r was the most prescribed (n  =  73; 63.5%). The average gain of LTCD4 has evolved from + 236 cells/mm³ in 2011 to + 364 cells/mm³ in 2015. The retention rate at grade 5 was about 70%. Conclusion: The immunological and clinic response of the patients was satisfactory. More than half of the patients remained in the continuum of care after five years of follow-up.
