연구배경 : Diffuse panbronchiolitis(DPB)는 1966년 일본에서 처음 기술된 만성 염증성 호흡기질환으로 기관지천식, 폐기종, 만성기관지염, 기관지확장증, 또는 폐포염과는 구별되는 질환이며 주로 일본에 많이 보고되었고, 중국 및 서구의 몇나라에서 증례보고가 있었으며, 본 교실에서도 최근 한국인에서의 DPB 환자의 임상적특징을 보고한 바 있다. DPB는 과거에 대증요법과 steroid 치료이외에 특별한 치료법이 없어 호흡부전으로 진행하여 사망하는 아주 예후가 좋지 않은 질환으로 알려졌었으나, 최근에 erythromycin의 소량장기투여가 효과가 있다는 보고가 나오고 있다. 본 교실에서는 1989년 9월부터 1993년 8월까지 서울대학교병원에서 병리학적 또는 임상적으로 DPB로 진단받은 환자 19명 중 erythromycin으로 치료하면서 6개월 이상 추적하고 있는 14명의 환자를 대상으로 erythromycin의 소량장기투여 효과를 분석하여 보고하고자 한다. 방법 : Erythromycin을 250 mg b.i.d.로 투여하고 치료전, 치료 3개월, 6개월 및 12개월 후에 환자의 자각증상, 흉부청진소견, 폐기능검사, 흉부X선검사의 변화를 관찰하였다. 결과: 1) 평균 치료 및 추적기간은
Background : Diffuse panbronchiolitis(DPB) is a chronic inflammatory lung disease of unknown etiology which has characteristic clinical, radiological and pathological features, and is distinguished from bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, or alveolitis. Clinically, patients with DPB have chronic cough, purulent sputum, exertional dyspnea, and finally respiratory failure. Until a few years ago, the prognosis of DPB had been thought to be very grave, because there had been no effective treatment for the disease. But recent1y, low-dose long-term erythromycin was found to be very effective on DPB. Even though DPB is prevalent in Japan, and is known to be rare outside of Japan, we have a1ready reported the clinical features of 16 DPB cases in Korea. We tried low-dose long-term erythromycin on DPB patients and analyzed the clinical effect of erythromycin. Methods : We analyzed the changes of subjective symptoms, physical signs, pulmonary function tests and chest X-rays on 14 DPB patients with more than 6 months erythromycin treatment during the period from September 1989 to August 1992 in Seoul National University Hospital. Results : 1) Subjective symptoms improved in all patients within 2-3 months, and 54.5% of the patients showed no symptom after one year of treatment. 2) Crackles and wheezing decreased in 92.9% of the patients after 3 months and completely disapppeared in 63.5% of the patients after one year of treatment. 3) FVC and FEV1 increased remarkably during the first 3 months, and slowly increased thereafter, reaching normal level after one year of treatment. 4) Small nodular lesions on chest X-ray decreased in all patients, and chest PA was normal in 36.4% of the patients after one year of treatment. 5) There was side effect in one patient, stopping medication because of dyspepsia. One patient stopped medication because of no symptom after 16 months of treatment, but her symptom recurring after one month, improving again after retreatment. Conclusion: Low-dose long-term erythromycin showed ramarkable effectiveness on DPB. Further studies are needed on the mechanism of the drug and the duration of the treatment.
