Title: 4-, 5- and 6-month regimens containing isoniazid, rifampicin, pyrazinamide and streptomycin for treatment of pulmonary tuberculosis under program conditions in Hong Kong
Abstract: Ten full time urban government chest clinics in Hong Kong.To assess the effectiveness of 4-, 5- and 6-month fully supervised thrice-weekly regimens containing 4 months of isoniazid, rifampicin, pyrazinamide and streptomycin followed by nil, 1 or 2 months of isoniazid and rifampicin for the treatment of smear-negative culture-negative, smear-negative culture-positive and smear-positive pulmonary tuberculosis.Retrospective study of the 3 antituberculosis treatment regimens given under program conditions during a 6-month period in 1983.Of the 1616 patients assessed, 953 (59%) completed their treatment strictly as planned, 443 (27%) had their treatment prolonged, 107 (7%) had their treatment modified and 113 (7%) defaulted or did not complete their treatment as planned. There were 2 treatment failures at the end of chemotherapy. At 60 months of follow-up, 67 patients died, 2 from the sequelae of tuberculosis. Of 1287 patients assessable up to 60 months, a total of 47 (3.7%) patients relapsed and were eventually treated successfully. 11 (20%) relapses occurred among the 55 patients who had defaulted and did not complete treatment as planned.The effectiveness of the 3 treatment regimens depended very much on the patient's adherence to treatment. The necessity of prolongation of treatment is not known and requires further assessment.
