摘　　要：目的评价乙型肝炎核心相关抗原(HBcrAg)对慢性乙型肝炎患者拉米夫定(LAM)耐药的预测作用。方法收集2009年1月至2011年12月期间住院和门诊收治的43例慢性乙型肝炎初治患者,拉米夫定治疗≥6个月,随访≥6个月,根据随访期间HBV DNA测序结果分为耐药组21例,非耐药组22例。分别检测各研究节点ALT、HBsAg、HBeAg、HBcrAg、HBV DNA水平。计量资料两组间比较采用独立样本t检验,方差不齐采用Mann-Whitney U检验;计数资料采用卡方检验。相关性分析采用Spearman分析。影响因素采用Logistic回归分析。结果 LAM抗病毒前HBcrAg与HBV DNA水平有较好的一致性,Spearman相关系数为0.863(P<0.001)。LAM抗病毒治疗后,外周血HBcrAg与HBV DNA水平均有所下降,但HBcrAg下降速度与幅度均低于HBV DNA。Logistic回归分析显示,随访结束时HBcrAg水平可能为LAM耐药的影响因素(P<0.01)。HBcrAg对LAM耐药预测价值较高,ROC曲线下面积为0.872(P<0.001)。结论 LAM抗病毒前外周血HBcrAg与HBV DNA有较好的一致性,随访结束时HBcrAg水平可较好的预测LAM耐药。To evaluate the predictive value of hepatitis B virus （HBV） core -related antigen （HBcrAg） for the lamivudine （LAM） resistance in patients with chronic hepatitis B. Methods Forty - three patients with previously untreated chronic hepatitis B who were treated in the inpatient department and outpatient department from January 2009 to December 2011 were enrolled. These patients received treatment with LAM for at least 6 months and were then followed up for at least 6 months. They were divided into resistance group （ n =21 ） and non -resistance group （n =22） according to the HBV DNA sequencing results during follow up. ALT, HBsAg, HBeAg, HB- crag, and HBV DNA levels at different time points were measured. Comparison of continuous data between the two groups was made by in- dependent - samples t test, and Mann - Whitney U test was used if heterogeneity of variance was identified ; categorical data were analyzed by chi - square test ; correlations were determined by Spearman analysis ; the influential factors were determined by logistic regression analy- sis. Results Before treatment with LAM, there was a significant positive correlation between the HBcrAg and HBV DNA levels in peripheral blood （ Spearman correlation coefficient r =0. 863, P 〈0. 001 ）. After the initiation of LAM therapy, both HBcrAg and HBV DNA lew^ls decreased, and the decrease in HBcrAg level was significantly slower and smaller than that in HBV DNA level. The logistic regression analy- sis showed that HBcrAg level at the end of follow - up might be an influential factor for LAM resistance （ P 〈 0.01 ）. HBcrAg had a high predictive value for LAM resistance, with an area under the ROC curve of 0. 872 （P 〈 0. 001 ）. Conclusion There is a significant positive correlation between HBcrAg and HBV DNA levels in peripheral blood before LAM administration, and the HBcrAg level at the end of follow - up has a high predictive value for LAM resistance in patients with chronic hepatitis B.
