Abstract
Background : The frequency of MOTT has risen as the prevalence of tuberculosis has been declining. Our country has been also. The most of MOTT was resistant to the major anti-tuberculous drugs. Method : To compare clinical characteristics and frequencies of MDR tuberculosis with MOTT, the author studied 65 patients showing AFB culture positive with sputum. The data were collected from 176 patients who had been admitted at the National Masan Tuberculosis Hospital from May to June, 1997 to April, 1998. Result : The frequency of MDR tuberculosis was 43.1% and that of MOTT was 9.2%. Among 65 isolated mycobacteria, 3 cases were M. intracellulare. 2 cases were M. fortuitum, and 1 case was unidentified MOTT. The most frequent age group in 65 culture positive patients was 4th decade and the mean age was 44. The mean age was 61 in MOTT and 42 in M. tuberculosis and had significant difference(p<0.01). The numbers with past history of treatment were 2.3 in MDR tuberculosis and 1.7 in non-MDR tuberculosis and had significant difference(p<0.05). At the time of admission, the most frequent regimen for the treatment of MDR tuberculosis was 24 months regimen(85.7%) with the 2nd line anti-tuberculosis drugs. For non-MDR tuberculosis, 9 or 12 months regimen (72.9%) with the 1st line anti-tuberculosis drugs and had significant difference (p<0.01). At the time of admission, the symptom of weight loss was shown in 84.7% of M. tuberculosis and 50.0% in MOTT and there was significant difference(p<0.05) between them. All of the MOTT were identified to be resistant against INH and PAS. Drug resistance rates to INH, OFX(p<0.01) and PAS(p<0.05) in MOTT were higher than in MDR. All of three M. intracellulare strains were resistant to INH, RFP, PAS and OFX. All of two M. fortuitum strains were resistant to most anti-tuberculosis drugs. And the other MOTT was resistant to INH, EMB and PAS. Conclusion : MOTT was more common in elderly patients than M. tuberculosis. MOTT cases should be considered to be the probability of multiple drug resistance and treatment failure during the 1st treatment because they showed more resistance to anti-tuberculosis drugs than M. tuberculosis cases. Therefore, there should be more careful investigations for clinical characteristics, natural history of disease, and efficient management for MOTT.
