Two short-term (20 weeks) chemotherapy regimens, one consisting of of INH, Streptomycin and Ethambutol and the other Pyrazinamide, INH, Streptomycin and Ethambutol were compared with a standard regimen of Streptomycin and INH Tor 8 weeks followed bv INH and Thiacetazone for 72 weeks. Two hundred and twenty seven patients in all were randomly allocated to the 3 regimens. Toxic reactions were negligible in all regimens. Patients in the trial regimens were hospitalized for the entire duration of chemotherapy viz. 20 weeks and patients in the standard regimen wore hospitalized only for the first 8 weeks. All patients took the drug with a high degree of regularity. Sputum conversion at the completion of treatment was nearly 100% in all 3 regimens. Radiological changes were also more or less similar. Patients were followed for a total period of 132 weeks. The rate of worsening in the follow up period up period was 16.4% in the Rifampicin regimen, 32.2% in the Pyrazinamide regimen and 11.2% in the control regimen. The observed rate of worsening was more amongst those with more extensive disease, cases with multiple cavities and those who took longer time to get converted initially although these differences did not attain statistical significance. Sputum conversion rate was fairly high even in patients with initial drug resistance.
