  • 摘要:   目的  探讨SH2B1 rs7359397 (C>T)基因多态性与北京地区老年人群代谢功能障碍相关脂肪性肝病(MASLD)患者肝纤维化进展的关系,为我国老年MASLD患者的精准分型、预后评估及个体化治疗提供重要的遗传学依据。  方法  纳入2020年11月—2021年9月在北京京煤集团总医院门矿医院参与定期体检且经腹部超声检查诊断为MASLD的老年患者(年龄≥65岁)为MASLD组(n=505),对照组为在同一时期、同一社区参与体检,且经腹部超声检查未发现脂肪肝的老年人群(n=381)。使用FibroScan检测肝脏脂肪含量和肝纤维化分期。采用96孔微流控芯片技术检测SH2B1 rs7359397基因多态性。符合正态分布的计量资料两组间比较采用成组t检验,计数资料两组间比较采用χ²检验或校正χ²检验。采用单因素和多因素Logistic回归分析确定MASLD及其相关合并症的独立预测因素。  结果  与对照组相比,MASLD组患者年龄更小,腰围、臀围、腰臀比、BMI、ALT、AST、TG和PLT均较高,HDL-C水平较低(P值均<0.05)。对照组381例研究对象中CC型264例(69.29%),CT+TT型117例(30.71%);MASLD组505例患者中CC型317例(62.77%),CT+TT型188例(37.23%)。MASLD组的CT+TT基因型占比显著高于对照组(χ²=4.09,P=0.043)。在MASLD患者中,与基因型CC组相比,CT+TT组FIB-4≥2的比例和动脉粥样硬化性心血管疾病的占比更低(P值均<0.05);进一步多因素Logistic回归分析结果显示,校正年龄、性别和BMI后,携带T等位基因是进展期肝纤维化的保护因素(OR=0.481,95%CI:0.249~0.929,P=0.029)。在合并高血压、代谢综合征及肥胖亚组中,CT+TT基因型与进展期肝纤维化风险显著降低相关联(高血压:OR=0.27,95%CI: 0.09~0.77,P=0.014;代谢综合征:OR=0.30,95%CI:0.11~0.79,P=0.015;肥胖:OR=0.11, 95%CI:0.03~0.48,P=0.003)。校正年龄、性别和BMI后,MASLD患者中,CT+TT基因型比CC基因型患者动脉粥样硬化性心血管疾病患病率显著降低(OR=0.506,95%CI:0.336~0.761,P=0.001)。  结论  SH2B1 rs7359397(C>T)基因多态性与MASLD患者的肝纤维化和动脉粥样硬化性心血管疾病风险降低有关。
