Abstract
AIM
Low baseline viremia and an early treatment response predict the best outcomes in hepatitis B virus (HBV) infected patients treated with nucleoside analogs with low barriers to resistance. The aim of this study was to assess the long-term results and effectiveness of lamivudine in patients with low baseline viremia and early virologic treatment response.
METHODS
In this multicenter, real-life setting study, 111 antiviral-naive patients with low baseline viremia (HBV DNA <7 log copies/ml) plus early virologic response (HBV DNA <300 copies/ml at week 24) with lamivudine treatment were enrolled. The primary end point was treatment failure, defined as re-emergence of detectable viremia or at least a 1 log increase in HBV DNA, resulting in a level of ≥300 copies/ml with lamivudine treatment after week 24, necessitating treatment modification.
RESULTS
Of the 78 non-cirrhotic patients (94% HBeAg negative, 68% male), treatment failure occurred in 31% of the patients over a median follow-up period of 33 months. The treatment failure rates were 7%, 14%, 31%, 40%, and 43% at years 1, 2, 3, 4 and 5, respectively. In the overall group (93% HBeAg negative, 72% male), treatment failure occurred in 29% of the patients. There were no differences between the cirrhotic and non-cirrhotic patients.
CONCLUSIONS
Lamivudine treatment had a high treatment modification rate in patients with low baseline viremia and early virologic response over a long-term follow-up in a ‘real-world’ setting. The pretreatment and on-treatment favorable characteristics derived from telbivudine studies appeared not to be valid for lamivudine. 作者: StephenW 时间: 2015-2-26 08:21
在这个多中心,现实生活设置的研究中,111抗病毒初治患者与低基线病毒血症(HBV DNA <7日志拷贝/毫升),加上早期病毒学应答(HBV DNA <300拷贝在24周/毫升),与拉米夫定治疗被纳入。初级终点是治疗失败,定义为重新出现可检测的病毒血症或至少1个对数增加的HBV DNA,导致≥300拷贝/ ml拉米夫定治疗24周后的水平,因此需要治疗的修改。
结果
Lamivudine treatment had a high treatment modification rate in patients with low baseline viremia and early virologic response over a long-term follow-up in a ‘real-world’ setting.
