[THE FREQUENCIES AND MANAGEMENT OF ADVERSE REACTIONS IN MULTI-DRUG RESISTANT TUBERCULOSIS TREATMENT].

[Objectives] To investigate the adverse reactions of antimicrobial drugs in multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR- TB) patients. [Results] Sixty-six patients with MDR-TB who have been treated from 2010 through 2014 were evaluated in the retro- spective analysis. Variety of adverse reactions including psychological reaction, central nervous system toxicity, ophthalmic toxicity, peripheral neurotoxicity, gastrointestinal reactions, hematologic abnormalities, musculoskeletal adverse effects, and endocrine disorder, were observed. However, there was no fatal case due to the adverse reactions of the anti-tubercu- losis drugs in this observation. [Conclusions] Drugs for MDR-TB and XDR-TB treatment are limited and the adverse reactions of drugs for MDR-TB and XDR-TB are not well-known. Therefore, the treatment may fail due to inappropriate management of adverse events. MDR-TB and XDR-TB should be treated by the experts of the adverse reactions of all anti-tuberculosis drugs.
