Аннотация
BACKGROUND: Extensively drug-resistant tuberculosis (XDR-TB) has recently been identified as a major threat to global health. XDR-TB poses a risk of higher failure rates and death during TB treatment. We report herein the outcomes of XDR-TB in patients treated with the standardized regimen in Iran.
PATIENTS AND METHODS: Between 2002 and 2006, seven patients were diagnosed with XDR-TB. All patients were treated with the standardized second-line regimen containing cycloserine, prothionamide, amikacin, and ofloxacin. First-line drugs, such as ethambutol and pyrazinamide, were added to the regimen if drug susceptibility testing showed sensitivity to these drugs.
RESULTS: Four (57.1%) patients were male. All seven patients were HIV-negative. The patient age range was 22-79 years. Of the seven cases, the final outcome was 'cure' in two (28.6%), 'relapse' in one, 'treatment failure' in one, and 'death' in two; the outcome for one patient was unknown.
CONCLUSION: Our study shows a poor prognosis in patients with XDR-TB. This indicates the necessity of detecting XDR-TB cases earlier, as well as the need to gain access to more second-line agents. This is particularly important in resource-limited settings in order to administer individualized regimens.
