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/mm 3 in 2011 to + 364 cells/mm 3 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.

La sacroiliite tuberculeuse est rare et de diagnostic difficile. Les auteurs rapportent deux cas. Il s'agissait dans le premier cas d'une patiente de 40 ans ayant une infection à VIH ; le diagnostic a été histologique après une biopsie chirurgicale. Le second cas a concerné un patient de 25 ans vivant en milieu carcéral chez qui le diagnostic a été établi sur la base des arguments cliniques, biologiques, radiologiques et l'efficacité du traitement ; l'intradermoréaction à la tuberculine était phlycténulaire. Le scanner a été indispensable au diagnostic lésionnel en montrant une érosion des berges et des abcès des parties molles. Le traitement a été médical et a fait appel aux antituberculeux.
