  • 摘要:   目的  本研究基于临床数据,探讨内脏脂肪面积(VFA)是否为非酒精性脂肪性肝病(NAFLD)患者发生显著肝纤维化的独立危险因素,并据此构建一个有效的诊断模型。  方法  纳入2021年1月—2025年4月于广东省中医院肝病科就诊的222例NAFLD患者,根据肝硬度值是否≥8 kPa,分为显著肝纤维化组和无显著肝纤维化组,并应用倾向性评分匹配(PSM)进行1∶1配对以平衡2组基线资料。计量资料两组比较采用成组t检验或Mann-Whitney U检验。计数资料组间比较采用χ2检验。通过Spearman相关性分析明确VFA及其他指标与显著肝纤维化的相关性;进一步采用单因素和多因素Logistic回归分析明确VFA是否是NAFLD患者发生显著肝纤维化的独立影响因素,并绘制受试者操作特征曲线(ROC曲线)评估相关指标的预测效能。  结果  共纳入显著肝纤维化45例,无显著肝纤维化177例,经PSM后最终纳入90例(45对)患者。与无显著肝纤维化组相比,显著肝纤维化组的体重指数(BMI)、空腹血糖(FBG)、糖化血红蛋白(HbA1c)、尿酸(UA)、丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、γ-谷氨酰转移酶(GGT)、受控衰减指数(CAP)、VFA水平更高,内脏脂肪型肥胖、合并3种及以上的代谢危险因素比例更高(P值均<0.05)。VFA、BMI、AST、HbA1c与显著肝纤维化呈强相关(r值均>0.5,P值均<0.05),ALT、GGT、UA、FBG、CAP、内脏型肥胖亦与显著肝纤维化显著正相关(r=0.3~0.5,P值均<0.05)。VFA(OR=1.040,95%CI:1.018~1.062)、FBG(OR=2.372,95%CI:1.199~4.691)、AST(OR=1.032,95%CI:1.003~1.058)是NAFLD患者发生显著肝纤维化的独立危险因素(P值均<0.05)。由VFA、FBG、AST构建的新型诊断模型对NALFD显著肝纤维化的预测效能(AUC=0.907)优于天冬氨酸氨基转移酶/血小板比值指数(AUC=0.834)、纤维化-4指数(AUC=0.660)、甘油三酯-葡萄糖指数(AUC=0.656)、NAFLD纤维化评分(AUC=0.768),差异均具有统计学意义(P值均<0.05)。  结论  VFA是NAFLD患者发生显著肝纤维化的独立影响因素,基于VFA、FBG及AST构建的无创诊断模型能有效预测NAFLD患者发生显著肝纤维化。
