不同HBV感染自然史状态及肝硬化患者抗-HBc水平及其临床意义

摘要

Objective To investigate the serum anti-HBc level in patients with different natural history of chronic hepatitis B virus (HBV) infection and cirrhosis,and its clinical value for distinguishing the natural history statue.Methods A total of 160 patients with chronic HBV infection from March 2015 to June 2016 were enrolled,and they were divided into immune tolerance group (n=43),HBeAg-positive chronic hepatitis B (CHB) group (n=37),inactive carrier group (n=39) and HBeAg-negative CHB group (n=41).A total of 44 patients with HBeAg-positive cirrhosis and 46 patients with HBeAg-negative cirrhosis were enrolled too.The general conditions data were collected,and HBsAg,HBeAg,anti-HBc,HBV DNA load and HBV genotype were detected.The associations between anti-HBc level and clinical parameters were analyzed,and the diagnostic value of anti-HBc for distinguishing different natural histories was analyzed.Results The anti-HBc levels in different natural history from high to low were as following: HBeAg-positive CHB group (4.22±0.68)log10 IU/mL,HBeAg-negative CHB group (3.89±0.88)log10 IU/mL,inactive carrier group (3.07±0.68)log10 IU/mL and immune tolerance group (2.88±0.82)log10 IU/mL.The anti-HBc levels in HBeAg-positive and HBeAg-negative cirrhosis patients were (3.04±0.82) and (3.15±0.86) log10 IU/mL,respectively.In HBeAg-positive CHB group,the anti-HBc was positively associated with ALT (r=0.353,P=0.032) and AST (r=0.421,P=0.009).In HBeAg-negative CHB group,the anti-HBc was positively associated with HBV DNA (r=0.343,P=0.028),ALT (r=0.458,P=0.003) and AST (r=0.495,P=0.001).The AUC of anti-HBc used to distinguish immune tolerance from HBeAg-positive CHB was 0.903,and the AUC used to distinguish inactive carrier from HBeAg-negative CHB was 0.833.Conclusion Anti-HBc levels in different natural history of chronic HBV infection are significantly different,and anti-HBc could be used to distinguish the natural history statue of chronic HBV infection with a higher diagnostic value than HBsAg.%目的 研究慢性乙型肝炎病毒(HBV)感染不同自然史状态及肝硬化患者血清乙型肝炎病毒核心抗体(抗-HBc)水平及其用于自然史状态区别诊断的临床价值.方法 纳入2015年3月至2016年6月就诊的慢性HBV感染患者160例,根据自然史状态分为免疫耐受组(n=43)、乙型肝炎病毒e抗原(HBeAg)阳性慢性乙型肝炎(CHB)组(n=37)、非活动携带组(n=39)及HBeAg阴性CHB组(n=41),同时纳入HBeAg阳性(n=44)及阴性肝硬化患者(n=46).收集患者一般情况,检测血清乙型肝炎病毒表面抗原(HBsAg)、HBeAg、抗-HBc、HBV DNA载量及HBV基因型.分析抗-HBc与临床指标的相关性及其用于自然史状态区别诊断的价值.结果 不同自然史状态抗-HBc由高至低为:HBeAg阳性CHB组(4.22±0.68)log10 IU/mL、HBeAg阴性CHB组(3.89±0.88)log10 IU/mL、非活动携带组(3.07±0.68)log10 IU/mL及免疫耐受组(2.88±0.82)log10 IU/mL.HBeAg阳性及阴性肝硬化患者抗-HBc分别为(3.04±0.82)、(3.15±0.86)log10 IU/mL.HBeAg阳性CHB组抗-HBc与ALT(r=0.353,P=0.032)及AST(r=0.421,P=0.009)呈正相关;HBeAg阴性CHB组抗-HBc与HBV DNA(r=0.343,P=0.028)、ALT(r=0.458,P=0.003)及AST(r=0.495,P=0.001)呈正相关.抗-HBc区别诊断免疫耐受状态及HBeAg阳性CHB的AUC为0.903,区别非活动携带状态及HBeAg阴性CHB的AUC为0.833.结论 不同慢性HBV感染自然史状态下血清抗-HBc水平存在明显差异,且抗-HBc可用于慢性HBV感染自然史状态的区别诊断,诊断价值高于HBsAg水平.
