[Results of tuberculosis treatment in a health district in Zaire].

The results of the treatment of tuberculosis have been evaluated among 407 patients distributed into 268 cases of pulmonary tuberculosis with positive smears (TP+), 70 pulmonary forms with negative smears (TP-) and 69 cases of extrapulmonary tuberculosis (TEP). A group 1 of 361 patients including new cases and late relapses and consisting of 236 TP+, 59 TP- and 66 TEP has been put through the treatment pattern: 2S6H7T7 + 10H7T7 or 2S6H7 + 10S2H2. Group 2, of 21 patients consisting of failures, early relapses and previously but irregularly treated cases, was given a pattern: 2R7E7H7Z7 + 10R2H2. In group 3, 25 new cases were given a short treatment: 2R7E7H7Z7 + 4R7H7. In group 1 we have recorded 68.42% cured patients, 8.59% failures and 14.40% neglects of treatment. The remaining 8.59% include deceased, transfers and patients put through extended treatment. The rate of cure was better among TEP patients (95.46%) than among TP- patients (79.66%) and TP+ patients (58.05%); failures were proved to be more frequent among TP+ patients (11.88%) than among TP- patients (3.39%) and TEP patients (1.51%). In group 2 and 3 successes have amounted to 95.24% and 84% respectively. Considering rates of cure, irregular treatments, neglects and failures with standard patterns (group 1), it appears to be desirable that rifampicin-including short patterns are added to antitubercular therapeutic strategies of developing countries.
