A Clinical Effect of Retreatment by Prothionamide, Cycloserine, Para-Aminosalicylic Acid, Streptomycin (Kanamycin or Tuberactinomycin) on Pulmonary Tuberculosis

폐결핵 재치료의 Prothionamide, Cycloserine, Para-Aminosalicylic Acid, Streptomycin (Kanamycin or Tuberactinomycin) 4제 요법 임상 효과

Background:In the management of patients whose primary chemotherapy has failed, very careful assessment is essential. It is important to find out as accurate a chemotherapy history as possible. Preferably it should contain the drugs which has never used before. The present report concerns the results of retreatment of pulmonary tuberculosis patients treated at National Kongju Tuberculosis Hospital. Method: A retrospective study was made through the regular follow-up of 112 smear positive cases, who were treated by four-drug regimen between July 1985 and June 1990. Four drugs were, namely prothionamide, cycloserine, para-aminosalicylic acid, and streptomycin (kanamycin or tuber-actinomycin). The duration of follow-up was over one year. Results: 1) Out of 112 cases with positive sputum AFB smear, 72 (64%) achieved the negative conversion. 2) Among the 72 patients, 85% achieved negative conversion within 3 months after treatment. 3) When the duration of patient's illness was less than 2 years, 2 to 4 years and more than 5 years, the favourable response to retreatment was 86%, 62% and 54%, respectively. 4) When the number of sensitive drugs was 4,3,2 and 1, the favourable response rate was 74%, 68%, 39% and 0%, respectively. Conclusion: The shorter the duration of patient's illness was, the larger the number of sensitive drugs was. And the larger the number of sensitive drugs was, the better the result of treatment was. Thus it is very crucial to successfully treat newly discovered patients with adequate regimens and proper case-holding.

PTA, CS, PAS, SM (KM 또는 TUM) 4제 요법의 임상효과를 알고자 지난 5년동안 국립 공주 병원에 입원하였던 도말양성 환자중 추적 가능한 112명을 대상으로 한 조사에서 다음과 같은 결과를 얻었다. 균 도말검사상 64%가 음전을 나타내었고 그 시기는 85%가 3개월 이내에 이루어졌다. 방사선 소견은 반응이 없는 경우가 약 반 정도이었으며, 세균학적 검사를 함께 고려하여 판단할 때 62% 정도만이 양호한 결과를 나타내었다. 양호한 결과는 병력이 짧고 내성정도가 적을수록 좋았다. 그리고 병력이 오래된 환자의 재치료 처방은 적어도 3제 이상의 감수성을 가진 약제를 선택해야 되며, 두가지 이하의 감수성이 있는 경우는 INH 단독 요법등의 고려가 필요할 것으로 사료된다.
