PURPOSE: The recommended duration of pulmonary tuberculosis therapy is 6 months. For extrapulmonary tuberculosis, treatment duration depends on tuberculosis involvement and HIV status. The objective of this study was to describe the main characteristics of a cohort of extrapulmonary tuberculosis patients, to compare patients with a 6-month treatment to those with more than a 6-month treatment, and to analyze the compliance of medical centres with recommended duration of treatment. METHODS: A retrospective cohort study of 210 patients with extrapulmonary tuberculosis was carried from January 1999 to December 2006 in two hospitals in the north-east of Paris. These patients were treated with quadruple therapy during two months, followed by dual therapy during 4 months (n=77) or more (n=66). The characteristics of each group were compared by uni- and multivariate analysis. The primary endpoint was the rate of relapse or treatment failure at 24-month follow-up after treatment completion. RESULTS: No relapse was observed after 24 months of follow-up after the end of treatment in the two groups. In univariate analysis, patients with lymph node tuberculosis were more often treated for 6 months than at other sites of tuberculosis (respectively 61% versus 40.9%; P=0.02); the decision of treatment duration was related to medical practices (79.2% treated 6 months in one hospital versus 20.7% in the other, P<0.001); patients living in private residence were more often treated during 6 months than patients living in residence (24.2% versus 10.3%, P=0.042). In multivariate analysis, only hospital (P=0.046), sex (P=0.007) and private residence were significantly different in each group. CONCLUSION: A period of 6 months seems to be sufficient to treat extrapulmonary tuberculosis (except for neuromeningeal localization).
