【Abstract】 Objective To evaluate the short and long-term effects of regimens containing INH、RFP with varied chemotherapy courses on culture-positive pneumoconio-tuberculosis. Method 79 patients with culture-positive pneumoconio-tuberculosis were divided into three groups according to chemotherapy duration: 9-months group(M9:2SHRZ/7HRE) 28 cases,12-month group(2SHRZ/10HRE) 25 cases, 18-month group(M18:2SHRZ/10HRE/6HR)26cases.Evaluating the efficacy of regimens depended predominantly on sputum bacteriological conversion, and the
patients who completed the regimens were followed up for 5~8 years. Result Sputum negative conversion rates of three groups at the end of chemotherapy were 83%, 96%, 95%,and their
recurrent rates in follow-up period 41%, 4% and 5% respectively.Of all patients who completed the regimens bacteriological relapse
rates from the first to fourth year are 6%, 8%, 2%, 2% in the follow-up period.There was no bacteriological relapse from fifth to eighth year. Conclusion It is effective for SHRZ/HRE combination with 12-months course to retreated tubercle bacillus positive pneumoconio-tuberculosis, and it is appropriate for such patients to be followed up for 4~5 years.
