ABSTRACT: Background: Ankylosing spondylitis is rare in sub-Saharan Africa. The purpose of our study was to report cases of AS in a black African population and to see the influence of gender. Method: It was a retrospective study conducted in the Rheumatology Department of Ouagadougou University Hospital, Ouagadougou, from March 2006 to February 28, 2015 for a period of nine years. All the patients who went under a rheumatology consultation during the study period were included. Patients with AS defined by the modified New York criteria were selected. Result: Forty-eight (0.61%) cases of AS were diagnosed among 7806 patients received in the rheumatology department during the study period. The search for the HLA B27 antigen in 20 patients was positive in 11 (55%). Half of the patients (50%) had a BASDAI score ≥ 4. Sacroiliitis was observed in all patients; it was stage 4 in 8 patients. Comparing by sex, there was no statistically significant difference by gender. Conclusion: Prevalence of ankylosing spondylitis increases. The presentation is similar to that of the caucasian series.
