摘要 患者徐某,女性,35岁,1年前乏力、食欲差就诊于消化科,化验谷丙转氨酶103U/L,谷草转氨酶134U/L,胆红素、肝炎病毒系列、腹部彩超均未见异常,予“易善复、双环醇”口服,1月后复查谷丙转氨酶265U/L,谷草转氨酶344U/L,抗核抗体(+),,抗线粒体抗体(±),抗SSA抗体(+),抗Ro-52抗体(+),诊断为“自身免疫性肝炎”,予“曲安西龙24mg.1/日口服”后,逐渐出现四肢近端肌肉无力,抬举及蹲起功能受限,2月后复查谷丙转氨酶305U/L,谷草转氨酶394U/L,为求进一步诊治收入院.查体:心肺腹部未见异常,躯干及四肢无皮疹,双上肢近端肌力3-级,双下肢近端肌力3级.无吸烟饮酒史.入院后查谷丙转氨酶483.0U/L、谷草转氨酶414.0U/L、磷酸肌酸激酶7364U/L、磷酸肌酸激酶同功酶593U/L、a-羟丁酸脱氢酶938U/L、乳酸脱氢酶1175U/L,血沉59mm/h,C反应蛋白76mg/L,血尿便常规、血脂、免疫球蛋白补体、肾功能、电解质、甲功全项、凝血功能、类风湿因子、肝炎病毒系列、肿瘤系列均正常,乙肝病毒DNA定量阴性,结核菌素试验(-);巨细胞病毒抗体、单纯疱疹病毒抗体、单纯疱疹病毒、弓形虫抗体、风疹病毒抗体均阴性(-);自身免疫抗体提示:抗核抗体(ANA)(+)、抗SS-A(52)抗体(+)、抗RO-52(+)、抗SRP抗体(+)、抗线粒体抗体(-),抗平滑肌抗体(-).查肌电图回报静息下双侧母短展肌、肱二头肌、三角肌、斜方肌、股内肌、股直肌、胫前肌可见少量正尖波、纤颤波,静息下被检双侧三角肌、肱二头肌、股内肌、股直肌可见多相波、双相波,左侧三角肌可见肌强直点位,轻收缩时MUP时限变短、波幅窄小,重收缩时呈病理干扰相改变.
