近日,英国国王学院医院(King's College Hospital)的学者在学术期刊《Journal of Viral Hepatitis》上发表了一篇题为“Can Quantitative Hepatitis B surface antigen levels predict the severity of liver disease in genotype E Patients?”的论文,探讨乙肝表面抗原定量水平是否能预测E基因型患者肝病的严重程度。

目前尚未完全证实乙肝表面抗原定量(qHBsAg) 水平是慢性乙型肝炎(CHB)相关肝损伤的标志,但是随着研究的深入,两者的关系越来越紧密了。乙肝表面抗原定量与e抗原阴性的BC基因型的肝病进展相关,但尚不清楚所有基因型是否与上述结果一致。在这个单中心、横断面观察研究中,我们评估了qHBsAg水平是否能预测E基因型患者肝病的严重程度。

方法:入组患者HBV DNA>2000 IU/mL 伴或不伴有ALT的异常。在对患者进行肝组织活检的同时评估了患者的人口学特征、病毒标记物、生化指标和qHBsAg水平。根据纤维化严重程度将患者分为三组:轻度(F0-1),中度(F2-4)、重度(F5-6),根据炎症坏死分级分为轻中度(NI 0 - 3)和重度炎症(NI≥4)

结果:共纳入259e抗原阴性的E基因型的初治慢乙肝患者。患者平均年龄为38岁,61%为男性。进展期(重度)纤维化患者ALTHBV DNA水平更高,qHBsAg水平更低,qHBsAg / DNA的比值更小。NI≥4的患者ALTHBV DNA水平更高,qHBsAg / DNA的比值更小。qHBsAgHBV DNA水平之间无相关性。

结论:肝脏纤维化越重,HBsAg水平较低。qHBsAgHBV DNA水平之间没有相关性。这可能反映了在HBeAg阴性的E基因型的进展期肝病患者中,HBV病毒的复制与转录活性或HBsAg特异性表达之间是不一致的。
