초록
목적 : 아데포비어는 라미부딘에 내성을 보이는 만성 B형간염 환자의 치료에 효과가 있는 비교적 안전한 약제로 알려져 있으나 비대상성 간경변증 환자에서의 국내 치료 성적에 관하여는 아직 알려진 바가 적다. 이에 본 연구자들은 라미부딘에 내성을 보이는 비대상성 간경변증 환자에서 아데포비어 투여의 효과와 안전성을 대상성 간질환 환자군에서의 성적과 후향적으로 비교 연구하였다. 대상과 방법 : 6개월 이상 라미부딘을 투여받은 18세 이상의 라미부딘에 내성을 보이는 만성 B형 간질환 환자에게 아데포비어 10 mg을 하루 1회 투여하였다. 이들을 비대상성 간경변증군과 대상성 간질환군으로 나누어 임상 경과 및 생화학적, 바이러스적 지표의 변화를 비교 분석하였다. 결과 : 총 101명의 환자(대상성 간질환군 48명, 비대상성 간경변증군 53명)가 연구에 포함되었다. 추적관찰 기간 동안 대상성 간질환군 중 4명과 비대상성 간경변증군 중 13명이 탈락되었는데(P=0.011), 중도 탈락된 환자들의 간기능 저하 정도가 계속적인 추적 관찰이 가능하였던 군에 비하여 유의하게 심하였다. 아데포비어 투여 후 비대상성 간경변증군의 HBV DNA 음전율은 50.9%로 대상성 간질환군의 83.3%에 비하여 유의하게 낮았으나 ALT의 정상화율, HBeAg의 음전율과 혈청전환율은 양군 간에 차이가 없었다. 비대상성 간경변증군에서의 Child-Pugh 점수는 9.1±1.8점에서 6.9±1.6점으로 유의하게 호전되었다(P<0.001). 대상성 간질환군의 생화학적 지표는 3개월째 대부분 호전된 후 유지되는 양상이었고 비대상성 간경변증군에서는 9개월까지 서서히 호전된 후 유지되는 양상이었다. 양군 모두에서 신장독성 등 아데포비어와 연관된 심각한 부작용은 관찰되지 않았다. 결론 : 이상의 결과로 라미부딘에 내성을 보이는 비대상성 간경변증 환자의 상당수에서 효과를 보이는 효과적이고 안전한 약제이나 그 효과는 대상성 간질환 환자에서보다 제한적이며 간기능의 호전 속도도 느림을 알 수 있었다. 따라서 라미부딘 내성을 보이는 비대상성 간경변증 환자에서 아데포비어의 조기 투여가 필요할 가능성을 시사하였다.
Abstract
Background/Aims: Adefovir dipivoxil is effective in patients with lamivudine-resistant hepatitis B virus (HBV). However, little is known about its role in Korean patients with decompensated liver cirrhosis. We retrospectively evaluated the efficacy and safety of adefovir dipivoxil in patients with decompensated liver cirrhosis with lamivudine resistance, and we compared this to the patients having compensated liver disease. Methods: The patients with lamivudine-resistant chronic liver disease were enrolled and they received adefovir dipivoxil 10 mg daily. The clinical course and the biochemical and virological response of the decompensated cirrhosis group were compared with those of the patients with compensated liver disease group. Results: One-hundred and one patients (the decompensated cirrhosis group, n=53; the compensated liver disease group, n=48) were evaluated. During the following up, 13 patients in the decompensated group and 4 patients in the compensated group dropped out of the treatment (P=0.011). After adefovir treatment, the proportion of patients with serum HBV DNA below 0.5 pg/mL in the decompensated group was less than that in the compensated group (50.9% vs. 83.3%, P=0.001), but the rates of normalized ALT, HBeAg loss and HBeAg seroconversion did not differ. The change of the Child-Pugh score in the decompensated group was 9.1±1.8 to 6.9±1.6 (P<0.001). The biochemical response in decompensated group was slower than that in the compensated group. Renal toxicity was not observed in either group. Conclusions: These results suggest that adefovir dipivoxil would be an effective and safe treatment for patients with decompensated liver cirrhosis with lamivudine resistance, but its effect might be limited and slower for decompensated cirrhosis.
