Abstract

Abstract Objectives: To determine the spectrum of SpA in outpatients with rheumatic complaints attending two rheumatology practices in the Democratic Republic of Congo. Design: A descriptive prospective multicenter outpatient study. Setting: The present study analyzed 6 months data (from December 1st, 2012 till May 31st, 2013). Participants: 984 consecutive outpatients were studied. Interventions: none Primary and secondary outcome measures: A clinical diagnosis of SpA was made and several classification criteria were applied afterwards. Sacroiliac joint radiographic lesions were scored with the modified New York criteria. BASDAI and BASFI were evaluated in axial SpA. The primary end point was the prevalence of SpA and the secondary endpoints were the spectrum of SpA and its subtypes. Results: One hundred and five patients (10.7%) were diagnosed among 984 consecutive outpatients with a sex ratio (male to female) of 1.4. The average age at disease onset was 41.3±12.4 years. Non-radiographical axial spondyloarthritis was the most frequent subtype (5.0%) followed by reactive arthritis (4.3%). Other subtypes were: ankylosing spondylitis (1.0%), psoriatic arthritis (0.1%), SAPHO syndrome (0.1%) and IBD associated arthritis (0.1%). Mean BASDAI and BASFI in axial SpA were 42.7/100 and 46.4/100 respectively. Peripheral enthesitis was found in 43% of SpA patients and uveitis (10.4%) was the most frequent extra-articular manifestation. We did not detect any family history. Median erythrocyte sedimentation rate and C reactive protein were 37(range: 7-110) mm/h and 22 (range: 4-48) mg/l respectively. Conclusions: This hospital-based study suggests a substantial occurrence of some subtypes of SpA in central Africa. A population-based study is needed.
