Paraclinical, Therapeutic and Evolutionary Profile of Osteoarticular Tuberculosis: A Report about 550 Cases in Abidjan

摘要

Objective: To describe paraclinical, therapeutic and evolutionary aspects of osteoarticular tuberculosis in Abidjan. Materials and Method: We realized a descriptive retrospective study carried out in the Rheumatology Department of the University Hospital Center of Cocody in Abidjan about 550 patients over a period of 10 years from January 2004 to December 2013. The paraclinical, therapeutic and evolutionary data had interested us. Results: Osteoarticular tuberculosis represented 12.13% of 4531 rheumatic diseases identified during the study period. The tuberculin skin test was positive in 78.49% of cases. An inflammatory syndrome was present with erythrocyte sedimentation rate and C-reactive protein respectively into 69.45% and 76.54% of cases. The research of Mycobacterium tuberculosis was realized into 176 of cases which 50% was positive. Polymerase chain reaction and biopsy of tissue were performed respectively in 8 and 6 cases. Plain radiography (89.82%) and computed tomography (83.63%) were the most realized imaging. Computed tomography has contributed for the diagnostic in 99.78% of cases. The majority of our patients (82.91%) received anti-tuberculous treatment which consisted of two months of combination of rifampicin (R), isoniazid (H), pyrazinamide (Z) and Ethambutol (E) (2RHZE), followed by 10 months of rifampicin (R) and isoniazid (H) (10 RH). The outcome in patients on this treatment was favorable in 528 cases (96%). Conclusion: This study revealed that the research of Mycobacterium tuberculosis was often realized and positive. On the contrary, polymerase chain reaction and biopsy of tissue were rarely performed. The main imaging is computed tomography. Our protocol of treatment is effective.
