摘要

Introduction: The occurrence of tuberculosis (TB) during the follow-up of Connective tissue diseases (CTD) is a particular situation often posing real diagnostic problems. This is an association described in the literature. Patients and methods: We conducted a retrospective and descriptive study at the internal medicine department of Aristide Le Dantec Hospital. The purpose of this study was to determine the treatment that patients followed for CTD and suffering from TB took before the occurrence of this one. Results: During a study period of 11 years and 6 months, 21 cases of TB were diagnosed in 602 cases of CTD (0.03%). The predominance was female with a sex ratio (H/F) of 0.6. The median age was 42 years old. The majority of cases originated from the Dakar region (13 patients or 61.9%) and 85.7% had previous follow-up exclusively in modern medicine and 21 cases (95%) received the CTD’s treatment. This consisted of prednisone (90.5%) combined with methotrexate (52.4%), azathioprine (23.8%) or cyclophosphamide (19.4%). The respective medians doses of these drugs were 12.5 mg per day for prednisone, 13.5 mg per week for methotrexate and 100 mg per day for azathioprine. The median duration of patient follow-up was 36 months. The cumulative dose of prednisone during this period was 23.6 g and that of methotrexate 2.25 g. CTD were dominated by rheumatoid arthritis (RA) (57.1%), and systemic lupus (19%). Isolated cases of systemic scleroderma, primary Sjôgren, SHARP syndrom, mixed connective tissue disease, and multiple autoimmune syndrom were noted. TB was localized in 95% of cases, readily bilateral and poorly disseminated. The respective medians diagnostic delays for systemic disease and TB were 21 months and 5 months. Tuberculin intradermal reaction was performed in 16 cases and was positive in 9 cases, sputum bacilli was performed in 19 cases and was positive in 15 cases. Conclusion: The association of TB and CTD was characterized by its rarity, its poorly disseminated character and its frequency on RA f
