摘 要:目的探讨CHB患者在不同自然阶段时血清HBsAg水平及其与肝组织病理学的关系,建立一种基于HBsAg的无创肝纤维化诊断模型。方法2013年1月至2015年1月住院接受肝活组织检查的CHB患者145例,其中HBeAg阳性73例。比较在不同自然史阶段以及不同HBeAg状态下患者HBsAg和HBV DNA水平。Logistic回归分析HBeAg阳性患者肝纤维化的影响因素,评价基于HBsAg的无创肝纤维化诊断模型——肝纤维化判别函数的预测价值。统计学处理采用ANOVA检验,两组间比较采用独立样本t检验。结果CHB患者在免疫耐受期、免疫清除期、低复制期、再激活期的血清HBsAg分别为(4.29±0.69)、(3.56±0.61)、(3.22±0.64)和(3.54±0.50) lg IU/mL(F=16.72,P〈0.01);HBV DNA分别为(8.48±0.58)、(6.69±1.44)、(3.80±0.59)和(6.21±1.06) lg拷贝/mL(F=76.73,P〈0.01)。HBeAg阳性患者肝组织炎症分级(G)≤G1、G2、G3、G4时的HBsAg分别为(4.44±0.65)、(4.00±0.72)、(3.74±0.62)和(3.28±0.50) lg IU/mL(F=9.198,P〈0.01);HBeAg阳性患者肝组织纤维化分期(S)≤S1、S2、S3、S4时的HBsAg分别为(4.55±0.54)、(4.04±0.89)、(3.59±0.63)和(3.34±0.50) lg IU/mL(F=10.66,P〈0.01)。Logistic回归显示,年龄(OR=1.091,95%CI:1.013~1.175)和HBsAg(OR=0.190,95%CI:0.066~0.542)是HBeAg阳性患者肝纤维化的独立影响因素。肝纤维化判别函数的受试者工作特征曲线下面积为0.849,高于AST与血小板比值指数(0.749)和基于4因子的肝纤维化指标(0.763)。结论血清HBsAg水平在CHB不同自然史阶段存在明显差异,HBeAg阳性患者血清HBsAg水平随着肝纤维化程度的进展而降低,以HBsAg定量建立的无创肝纤维化模型可以初步判断肝组织的纤维化程度。Objective To investigate the relationship between hepatitis B surface antigen (HBsAg) levels and liver pathology at different phases of natural history in chronic hepatitis B (CHB) patients, and to establish a non-invasive liver fibrosis diagnostic model based on HBsAg quantification. Methods A total of 145 CHB patients were enrolled and underwent liver biopsy from January 2013 to January 2015, among which 73 patients were hepatitis B e antigen (HBeAg) positive. HBsAg levels and HBV DNA levels were compared between patients at different phases of natural history and between patients with different HBeAg statuses. Logistic analysis was used to analyze the risk factors associated with fibrosis in H BeAg-positive patients, and to evaluate the predictive value of non invasive liver fibrosis diagnostic model based on HBsAg quantification. Analysis of variance was used for statistical analysis, and t test analysis was used for the comparison between two independent samples. Results The serum HBsAg levels at the immunologic tolerance phase, immunologic clearance phase, low copy phase and reactivation phase of CHB patients were (4.29±0.69), (3.56±0.61), (3.22±0.64), and (3.54±0.50) lg IU/mL, respectively (F=16.72, P〈0.01), and the HBV DNA levels were (8.48±0.58), (6.69±1.44), (3.80±0.59), and (6.21±1.06) lg IU/mL, respectively (F=76.73, P〈0.01). In HBeAg-positive CHB patients with liver inflammation stage (G)≤G1, G2, G3 and G4, the serum HBsAg levels were (4.44±0.65), (4.00± 0.72), (3.74±0.62), and (3.28±0.50)lg IU/mL, respectively (F=9. 198, P〈0.01). In HBeAgpositive CHB patients with liver fibrosis stage (S)≤S1, S2, S3, and S4, the serum HBsAg levels were (4.55±0.54), (4.04±0.89), (3.59±0.63), and (3.34±0.50) lg IU/mL, respectively (F=10.66, P〈0.01). Logistic analysis showed that age (OR = 1. 091, 95% CI: 1. 013-1. 175) and HBsAg level fORgO. 190, 95%CI: 0. 066-0. 542) were independe
