Tuberculosis in Lorraine, France: study of prognostic factors.

AIM: To identify factors predicting short-term mortality in patients with tuberculosis in the Lorraine region of France.

METHOD: Retrospective survey in nine voluntarily participating hospitals between January 1990 and December 1994.

RESULTS

In total 351 files were analyzed. The average age of patients was 49 +/- 19 years; 77% were of French origin, 60% were male; 35% were in paid employment at the time of the diagnosis, 42% were unemployed and 23% were retired. Twenty-three patients were infected by the human immunodeficiency virus (HIV), and 34 patients had a prior history of tuberculosis; 79% of all cases were exclusively pulmonary, 14% were exclusively extra-pulmonary (more frequent in women) and 7% were mixed. Extra-pulmonary sites of involvement were more frequent in HIV-infected patients. Chest X-ray was suggestive of tuberculosis in 158 patients with pulmonary involvement, and non-suggestive in 145 (more frequently in HIV-infected patients). In univariate analysis, HIV co-infection, increasing age and unemployment were linked to death during treatment. In multivariate analysis (logistic regression), HIV co-infection, old age, unemployment, pulmonary involvement and French origin were significantly linked to the risk of death during treatment.
