摘 要:目的比较乙型肝炎e抗原(HBeAg)阴性与阳性慢性乙型肝炎(CHB)患者血清细胞因子白细胞介素12(IL-12),IL-10及γ干扰素(IFN-γ)水平、肝功能、病毒载量及肝纤维化程度,研究HBeAg阴性和阳性CHB患者细胞因子作用,总结HBeAg阴性CHB病情特点。方法HBeAg阴性CHB患者33例与HBeAg阳性CHB患者41例,分别检测其肝功能指标:丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、总胆红素(TBil),乙型肝炎病毒脱氧核糖核酸(HBV DNA)定量,透明质酸(HA)、Ⅲ型前胶原(PC-Ⅲ)、Ⅳ型胶原(C-Ⅳ)、层黏连蛋白(LN)等肝纤维化指标,凝血酶原活动度(PTA),以及血清IL-12I、L-10及IFN-γ水平。结果HBeAg阴性CHB患者病程较HBeAg阳性CHB患者长,(6.8±6.2)年vs(3.8±4.0)年(P<0.05);两组患者肝功能和PTA在轻、中、重度组间比较差异均无统计学意义(P>0.05);HBeAg阴性CHB患者HBV DNA定量水平低于HBeAg阳性CHB患者,(5.1±1.4)vs(6.2±1.5)(P<0.05),IL-12I、FN-γ水平高于HBeAg阳性CHB患者,分别为(71.3±32.0)ng/L vs(57.7±23.1)ng/L、(16.1±4.8)ng/L vs(13.4±3.3)ng/L(P<0.05),两组IL-10水平比较差异无统计学意义(P>0.05);HBeAg阴性CHB患者肝纤维化指标LN重于HBeAg阳性CHB患者,(123.6±61.3)μg/L vs(91.6±45.6)μg/L(P<0.05)。结论HBeAg阴性CHB患者病程较长,与HBeAg阳性CHB患者肝功能损害轻、中、重度组比较差异无统计学意义;HBeAg阴性CHB患者HBV DNA复制水平低于HBeAg阳性CHB患者,IL-12、IFN-γ对HBeAg阴性CHB患者病情变化有非常重要的作用;HBeAg阴性CHB患者肝纤维化指标重于HBeAg阳性CHB患者,提示HBeAg阴性CHB患者较HBeAg阳性CHB患者更易向肝硬化发展。Objective To compare the levels of cytokines interleukin-12 (IL-12), interleukin-10 (IL-10), interferon-γ(IFN-γ) ,and degree of liver function, virus load and hepatic fibrosis between HBeAg negative and positive chronic hepatitis B(CHB) patients in the serum,investigate the role of cytokines in HBeAg negative and positive CHB, summarize the feature of HBeAg negative CHB. Methods To measure alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBil), hepatitis B virus deoxyribonucleic acid( HBV DNA) load, hyaluronic acid (HA), precollagen- Ⅲ (PC-Ⅲ), collagen-Ⅳ (C-Ⅳ), laminin (LN), plasrnozyrne activity(PTA) of 33 HBeAg negative and 41 HBeAg positive CHB patients,and detect levels of IL-12, IL-10, IFN-γ. Results The course of HBeAg negative CHB patients was longer than that of HBeAg positive CHB patients (6.8±6.2) years vs (3.8±4.0) years (P〈0.05). Liver function and PTA were not difference in mild, moderate and severe group (P〉0.05). HBeAg negative CHB HBV DNA load was lower than HBeAg positive CHB (5.1±1.4) vs (6.2±1.5)(P 〈0.05). IL-12 and IFN-γ were higher than those of HBeAg positive CHB (71.3±32.0) ng/L vs (57.7±23.1) ng/L, (16.1±4.8) ng/L vs (13.4±3.3) ng/L(P〈0.05), but IL-10 showed no significance (P〉0.05). Hepatic fibrosis index LN of HBeAg negative CHB was more severe than that of HBeAg positive CHB (123.6±61.3) μg/L vs (91.6±45.6)μg/L(P〈0.05). Conclusion The course of HBeAg negative CHB is longer than that of HBeAg positive CHB. Liver function damage has no difference between HBeAg negative and positive CHB in mild,moderate and severe group. HBV DNA load in HBeAg negative CHB is lower than that of HBeAg positive CHB,IL-12 and IFN-γ play an important role in HBeAg negative CHB. Hepatic fibrosis indexes of HBeAg negative CHB are more severe than those of HBeAg positive CHB,the results suggest that HBeAg negative CHB easily progress
