摘要
目的研究核苷(酸)类似物(NAs)治疗慢性乙型肝炎(CHB)的耐药趋势,指导临床用药。方法回顾性分析2006年至2009年3年NAs疗程中496例CHB患者HBV基因型、耐药特征及其分布、变化趋势。结果 3年共检出耐药变异株243例(48.99%),第一、二、三年耐药检出率分别为48.33%(58/120)、49.64%(69/139)和48.95%(116/237),拉米夫定耐药株检出率分别为45.0%(54/120)、44.6%(62/139)和36.7%(87/237),阿德福韦耐药株检出率分别为1.67%(2/120)、2.16%(3/139)和7.59%(18/237),恩替卡韦耐药株检出率分别为0.83%(1/120)、0.72%(1/139)和1.69%(4/237),多重耐药株检出率分别为0.83%(1/120)、2.16%(3/139)和2.95%(7/237)。其中阿德福韦耐药株及多重耐药株检出率有明显的逐年增加趋势(P<0.05)。结论随着NAs疗程的延长,NAs耐药变异株检出率,尤其是阿德福韦耐药株及多重耐药株检出率逐年增加。
Objective To monitor the tendency of drug resistance during nucleos( t) ide analogs therapy in the treatment of chronic hepatitis B. Methods The HBV genotypes,variation forms and the change tendency in 496 CHB patients were detected and analyzed retrospectively. Results A total of 243 mutation podients( 48. 99% ) were detected in the recent three years,the detection rate for each year was 48. 33% ( 58 /120) ,49. 64% ( 69 /139) and 48. 95% ( 116 /237) . For LAMr mutations,the rate was 45. 0% ( 54 /120) ,44. 6% ( 62 /139) and 36. 7% ( 87 /237) . For ADVr mutations,it was 1. 67% ( 2 / 120) ,2. 16% ( 3 /139) and 7. 59% ( 18 /237) . And for ENTr mutations,it was 0. 83% ( 1 /120) , 0. 72% ( 1 /139) and 1. 69% ( 4 /237) . While for multi-drug resistant mutations,the rate was 0. 83% ( 1/120) ,2. 61% ( 3/139) and 1. 69% ( 4/237) . Conclusion The longer the nucleoside analogs treatment course was,the more resistant mutations were detected. Especially for the ADVr,ETVr and multidrug resistance.
