PURPOSE: The optimal treatment regimen for Mycobacterium avium complex (MAC) lung disease has not yet been fully established. We evaluated the efficacy of standardized combination antibiotic therapy and the factors that might affect unfavorable microbiologic responses in patients with MAC pulmonary disease. MATERIALS AND METHODS: This retrospective study reviewed data from 96 patients (56 females; median age 59 years) treated with newly diagnosed MAC lung disease between January 2003 and December 2006. RESULTS: All patients received standardized combination antibiotic therapy, consisting of clarithromycin, rifampicin, and ethambutol. Streptomycin was additionally given in 72 patients (75%) for a median duration of 4.5 months. The overall favorable microbiologic response rate was 79% (76/96); 20 patients (21%) had unfavorable microbiologic responses, including failure to sputum conversion (n = 13), relapse (n = 3), and MAC-related death (n = 4). A positive sputum acid-fast bacillus smear at the start of treatment was an independent predictor of an unfavorable microbiologic response. CONCLUSION: Standardized combination antibiotic therapy consisting of clarithromycin, rifampicin, and ethambutol with or without initial use of streptomycin is effective in treating patients with newly diagnosed MAC lung disease.

OBJECTIVETo understand the determinants and epidemiology of drug-resistant tuberculosis (TB) in rural area.
METHODSAll the diagnosed TB patients in a county with directly observed treatment (DOTS) short-course program in 2002 and a sample of patients in another county without DOTS program located in northern Jiangsu province were surveyed with questionnaires. Drug susceptibility testing (DST) for positive cultures were performed by standardized proportion method. Univariable analysis and multivariate nonconditional logistic regression modeling were applied for data analysis.
RESULTSAmong the 152 patients with DST results, 32.9% of the cases showed resistance to at least one of the first-line anti-tuberculosis drugs with 26.3% to isoniazid, 18.4% to rifampin and 17.1% to both isoniazid and rifampin respectively. Previous treatments for TB and residence in the county without DOTS program were independent risk factors for isoniazid and rifampin resistance. TB patients showing indifferent to their health and delayed health seeking for more than 1 month were more likely to have rifampin resistance. Independent predictors of multidrug-resistant TB would include delayed health seeking for more than 1 month (OR = 4.66, 95% CI: 1.26 - 17.24), residing in the county without a DOTS program (OR = 3.01, 95% CI: 1.10 - 8.22), indifference to their health condition (OR = 5.13, 95% CI: 1.06 - 24.90) and suffering from chronic diseases (OR = 0.22, 95% CI: 0.05 - 0.87).
CONCLUSIONDrug-resistant TB was quite serious in this rural areas, mainly associated with man-made factors but partly due to the availability of the transmission.
