OBJECTIVE: To review the outcome for MDR-TB treatment among potential migrants from Vietnam. SETTING: All cases of documented MDR-TB treated by the International Organization of Migration (IOM) in Vietnam from 1989 to 2000 were reviewed. METHODS: MDR-TB was defined as isoniazid- and rifampicin-resistant Mycobacterium tuberculosis. All cases of TB treated by the IOM and recorded in the computerised database were reviewed to identify MDR-TB cases. Demographics, chest radiograph results, drug resistance, drug use and dosage, duration of treatment, and outcome were analysed. RESULTS: Forty-four cases of MDR-TB were identified. Treatment consisted of ambulatory directly observed treatment with an 8-drug protocol: isoniazid, rifampicin, pyrazinamide, ethambutol, capreomycin, ethionamide, ofloxacin and cycloserine. This initial protocol was modified due to drug availability or drug intolerance. Patients were treated with a median of 8 drugs (range 6-12). Mean duration of treatment for MDR-TB was 23.0 (SD+/-11.4) months. Thirty-eight (86%) patients were cured and emigrated, one failed treatment (2%), three were lost to follow-up (7%) and two died (4%). CONCLUSION: Treatment for MDR-TB provided by the IOM was effective in preparing a low-income population for migration.
The study of 52 strains of rapidly growing mycobacteria showed that Mycobacterium fortuitum and M. chelonei were clearly distinguished by the aid of seven key tests (nitrate reductase, iron uptake, beta-glucosidase, penicillinase, growth on fructose, resistance to pipemidic acid, and resistance to capreomycin) and by analysis of their respective mycolic acids. However, the subdivision of these species into M. fortuitum var. fortuitum and M. fortuitum var. peregrinum and M. chelonei subsp. chelonei and M. chelonei subsp. abscessus was not satisfactorily accomplished.
