摘要: 目前,急性重症自身免疫性肝炎(AIH)的诊断标准包括急性起病、符合AIH诊断标准,且诊断时存在黄疸、INR≥1.5、尚未出现肝性脑病以及无既往肝病证据。作为AIH的一类特殊亚型,急性重症AIH具有起病急、病情进展迅速的特点,早期诊断识别至关重要,一经诊断应及早给予糖皮质激素治疗,可降低患者进展至肝衰竭乃至接受肝移植的风险。该病的临床管理极具挑战性,诊断时患者往往缺少典型AIH的临床特征和组织学表现,早期评估激素应答反应,并给予适当剂量的治疗方案对于改善患者预后至关重要。Abstract: At present, the diagnostic criteria for acute severe autoimmune hepatitis (AS-AIH) include acute onset, consistency with the diagnostic criteria for autoimmune hepatitis (AIH), presence of jaundice, and international normalized ratio ≥1.5 at the time of diagnosis, without evidence of hepatic encephalopathy or previous liver disease. As a special subtype of AIH, AS-AIH is characterized by acute onset and rapid disease progression, and thus early diagnosis is of vital importance. Glucocorticoid therapy should be given as early as possible after diagnosis to prevent the progression to acute liver failure and reduce the risk of liver transplantation. Management of AS-AIH patients is challenging, since patients often lack typical clinical features and histological manifestations of AIH at the time of diagnosis, and early assessment of glucocorticoid response and a treatment regimen with proper doses are important for improving the prognosis of patients.
