Abstract:

目的 评估替比夫定与阿德福韦酯联合治疗优化阿德福韦酯单药治疗应答不佳的阳性慢性乙型肝炎患者的疗效。方法 选择2008年6月-2009年8月间共26例阿德福韦酯治疗至少12个月且病毒学应答不佳的乙型肝炎病毒e抗原(HBeAg),阳性的慢性乙型肝炎患者,在10mg阿德福韦酯治疗的基础上,加用600mg替比夫定。肝功能和乙型肝炎病毒(HBV)DNA每3个月评估1次,乙型肝炎两对半和腹部B型超声每半年评估1次。结果 在第1年的治疗期间,所有患者血清HBVDNA水平均呈进行性下降,其中24例(92.3%)血清HBVDNA水平在联合治疗12个月时低于检测值下限,有25例(96.2%)患者丙氨酸转氨酶水平复常。治疗6个月时,分别有7例(26.9%)和2例(7.7%)患者发生HBeAg消失和血清学转换;治疗12个月时,分别有11例(42.3%)和8例(30.8%)患者发生HBeAg消失和血清学转换。整个治疗期间,26例患者均未出现病毒学突破。结论 阿德福韦酯单药治疗应答不佳时,加用替比夫定可有效控制病毒,使患者获得较好的病毒学、生化学和免疫学应答。Objective Toevaluatethecurativeefficacyoftelbivudinecombinedwithdefovirdipivoxilonpositive-HBeAgchronichepatitisBpatientswithsuboptimalresponsetoadefovirdipivoxil.Methods Atotalof26HBeAg-positivepatientswithsuboptimalresponsetoadefovirdipivoxil(treatedwithadefovirdipivoxilformorethan12months)weretreatedwithadefovirdipivoxil10mginadditiontotelbivudine600mgbetweenJune2008andAugust2009.LiverfunctionandserumhepatitisBvirus(HBV)DNAtestswereassessedatthebaselineand3-monthintervals,whereasHBVserologicalmarkersandabdominalultrasonographywerecarriedoutevery6months.Results Duringthefirstyearoftreatment,allpatientsshowedaprogressivedeclineofserumHBVDNAlevels;whileundetectableserumHBVDNAandnormalizationofalanineaminotransferasewasachievedin24(92.3%)and25(96.2%)patients,respectively,attheendofthefirstyearoftreatment.The6-and12-monthcumulativeratesofHBeAglosswere26.9%(7/26)and42.3%(11/26),respectively;andcorrespondingcumulativeratesofHBeAg/anti-HBeseroconversionwere7.7%(2/26)and30.8(8/26),respectively.Duringtheobservationperiod,novirologicalbreakthroughwasdetected.Conclusion Telbivudinecombinedwithdefovirdipivoxilmaybeagoodchoiceforpatientswithsuboptimalresponsetoadefovirdipivoxil,whichcouldinduceeffectiveviralinhibitionandhelppatientsobtainmorevirological,biochemicalandimmunologicalresponses.
