摘要: 目的分析ALT轻度升高的慢性乙型肝炎患者肝组织病理学改变情况,以探讨ALT水平与肝脏炎症及纤维化分期的关系。方法选择216例ALT轻度升高的慢性乙型肝炎患者及83例慢性HBV携带者,进行肝活检,分析肝脏炎症分级(G)及纤维化分期(S)与ALT及年龄的关系。结果在肝炎组中,炎症分级≥G2者占55.6%,明显高于对照组(31.3%);肝炎组纤维化分期≥S2者占62.1%,也明显高于对照组(28.9%,P<0.01),均有显著性差异;在慢性肝炎组中年龄大于40岁者,肝组织炎症分级≥G2及纤维化分期≥S2者分别为69.5%及75.0%,均明显高于年龄<40岁组,差异具有统计学意义(P<0.01);在年龄大于40岁的患者中,ALT>60U/L者G3+4比例(52.9%)高于ALT<60U/L者(31.7%,P<0.05);ALT>60U/L者纤维化分级高(S3+4)者比例也明显高于ALT<60U/L者,差异具有统计学意义(P<0.05),ALT>60U/L组有84.3%纤维化分级≥S2,明显高于ALT<60U/L组(63.4%,P<0.05)。结论部分ALT轻度升高的慢性乙型肝炎患者肝组织病变也处于活动期,其中年龄大于40岁而ALT又大于60U/L者,应开始抗病毒治疗,达不到这个标准的患者应行肝组织活检来决定是否需要抗病毒治疗。

Abstract: Objective To analyze the hepatic pathohistology of biopsies in chronic hepatitis B patients with mild ALT elevation. Methods 216 liver biopsies from patients with chronic hepatitis B with ALT elevation (lower than two times upper limits of normal) and 83 with asymptomatic HbsAg carriers (ASC) were included for liver biopsies. Results 55.6% and 62.1% of patients with CHB had G2 or S2 ,respectively,much higher than those in the ASC group(P<0.01); The greater than G2 or S2 in patients with CHB over the age of 40 years were 69.5% or 75.0%,respectively,much higher than in patients younger than 40 years;In patients with chronic hepatitis B and with the age over 40 years,52.9% had G3 to G4 in those with ALT greater than 60u/L,much higher than 31.7% in patients with the ALT lower than 60U/L;The fibrosis above S2 staging was 84.3% in patients with ALT greater than 60U/L,much higher than that in patients with ALT lower than 60U/L. Conclusion Part of patients with CHB with mild ALT elevation have liver pathological changes.The patients over the age of 40 years and ALT higher than 60U/L should receive antiviral treatment.
