OBJECTIVES: To analyze the epidemiological, clinical and diagnostic characteristics of extrapulmonary tuberculosis in western France observed from 1991 to 1993 in different patients populations (HIV+ infected patients, immunosuppressed non-HIV infected patients, non-immunosuppressed patients) and according to various localizations (lymph nodes, bone and joints, genital organs, nervous system and meninges, miliary disease).
METHODS: This retrospective study included 217 cases of extrapulmonary tuberculosis diagnosed from 1991 to 1993 in western France by GERICCO (Groupe d'Epidémiologie et de Recherche en Infectiologie Clinique du Centre-Ouest). Demographic, clinical, biological, microbiological and radiographic characteristics as well as clinical course on specific therapy were assessed.
RESULTS: Extrapulmonary tuberculosis generally occurred most often in immunosuppressed patients but 34% of cases were observed in people without any underlying disease or risk factors. Delay to diagnosis was especially long in the non-immunosuppressed patients (mean = 96 days) but shorter in the HIV-infected patients (mean = 59 days). It was shorter in case of nervous system involvement (mean = 52 days) or military disease (mean = 80 days) than in bone and joints (mean = 120 days) and lymph nodes (mean = 102 days). Microbiologically proven tuberculosis represented only 75% of cases despite numerous investigations. Overall prognosis was good except in nervous system and meninges localizations. Failures were mainly due to death in immunosuppressed patients.
CONCLUSION: Extrapulmonary tuberculosis remains frequent even in patients lacking risk factors. In 50% of cases, confirmation of diagnosis takes more than one month. In case of doubt, clinicians should not wait for laboratory results before implementing empirical specific therapy.
