Setting: Individualised regimens based on drug susceptibility test results, generally used to treat multidrug-resistant tuberculosis (MDR-TB), require often unavailable expertise and resources.
Objective: To evaluate a standardised regimen based on the susceptibility profiles of locally prevalent MDR-TB strains.
Design: The activities of a successful DOTS programme in Bangladesh were complemented by offering treatment with a standardised 21-month regimen to patients with laboratory-confirmed MDR-TB disease. The regimen contained kanamycin, ofloxacin, prothionamide, pyrazinamide, ethambutol, isoniazid and clofazimine. Clinical and bacteriological progress was monitored quarterly until treatment completion, then 6 monthly for 2 years.
Results: The status at the end of treatment of this cohort of 58 documented MDR-TB patients was as follows: eight (14%) deaths, seven (12%) defaults, three (5%) failures and 40 (69%) cures. One bacteriologically-confirmed relapse was recognised. Frequent and sometimes serious side effects proved to be the main problem, suggesting the need for a better tolerated but equally effective regimen.
Conclusion: A standardised approach may provide a reasonable alternative to individualised treatment of MDR-TB in resource-poor settings. However, DOTS-plus programmes in resource-poor settings may confront significant difficulties in the enrolment, diagnosis and management of MDR-TB patients.
