  • 摘要:   目的  通过比较儿童慢性乙型肝炎(pCHB)患者血清转氨酶水平及其比值与肝组织炎症程度之间的关系,为pCHB患者治疗优势人群选择提供依据。  方法  收集中国人民解放军总医院第五医学中心2010年1月—2022年8月入院且未经抗病毒治疗的pCHB患者1 267例,分析患者的人口学特征、血常规、血生化、HBV血清学标志物和肝穿刺活检资料。根据肝穿刺活检炎症程度,将患者分为无或轻度炎症活动组(G0~G1)和显著炎症活动组(G2~G4),比较各组的血清转氨酶及其比值水平,分析其与pCHB患者肝脏炎症程度的相关性。同时,按照不同年龄分层,分析在不同年龄亚组中血清转氨酶水平与肝组织炎症程度的关系。正态分布的计量资料2组间比较采用成组t检验;非正态分布的计量资料2组间比较采用Mann-Whitney U秩和检验。计数资料2组间比较用χ2检验。相关性分析采用Spearman相关分析法。  结果  1 267例pCHB患者中G0~G1组468例(36.9%),G2~G4组799例(63.1%)。两组相比,AST、ALT、AST/ALT、GGT、总胆红素、直接胆红素、HBeAg定量、低密度脂蛋白、血小板水平差异均有统计学意义(P值均<0.05)。相关性分析显示,肝脏炎症活动程度与血小板、低密度脂蛋白水平呈负相关(P值均<0.05),与GGT、总胆红素、直接胆红素以及HBeAg滴度呈正相关(P值均<0.05),但与患者血清ALT、AST、AST/ALT比值均无相关性(P值均>0.05)。在0~12岁组、13~18岁男性组及13~18岁女性组患者中,肝脏炎症程度随着血清ALT、AST表达水平升高而加重,差异均有统计学意义(P值均<0.05)。0~12岁组AST/ALT>1与AST/ALT≤1相比,肝脏显著炎症活动度差异有统计学意义(P<0.001)。1 267例中ALT<2倍正常值上限(ULN)的患者447例(35.28%),其中G≥2有196例(43.85%),占所有入组患儿的15.47%。  结论  pCHB患者肝脏炎症活动程度与血清ALT、AST、AST/ALT比值无显著相关,血清转氨酶水平不能真实反映转氨酶<2×ULN的pCHB患者肝脏炎症活动;在临床实践中,针对转氨酶<2×ULN的患儿,建议行肝穿刺病理检查,进一步明确是否抗病毒治疗。
