摘要

摘要: 自身免疫性肝炎(AIH)是一种由免疫介导的肝细胞炎症性损伤，可进展为肝硬化及终末期肝病。及时给予免疫抑制治疗可使患者获得生化缓解甚至组织学缓解，进而改善预后。但治疗过程中由药物引起的不良反应及停药后复发的现象十分常见，因此规范治疗、适时减量、及时停药对于改善患者预后至关重要。归纳总结了国内外AIH诊治指南及相关研究进展，为临床医师治疗AIH提供一定的参考。

Abstract: Autoimmune hepatitis (AIH) is an immune-mediated inflammatory injury of hepatocytes, which can develop into liver cirrhosis and end-stage liver disease. Timely immunosuppressive therapy can help patients achieve biochemical remission and even histological remission and thus improve prognosis. However, adverse drug reactions during treatment and recurrence after withdrawal are commonly seen, and therefore, standard therapy, dose reduction at the right time, and timely drug withdrawal are important for improving patients' prognosis. This article summarizes the advances in guidelines for the diagnosis and treatment of AIH and related studies in China and globally, so as to provide a reference for clinicians in the treatment of AIH.

表 1 AIH相关免疫抑制药物与HBV再激活风险

HBV再激活风险分组	HBV血清特征及药物使用剂量和持续时间
高风险 (HBV再激活的发生率＞10%)	糖皮质激素治疗≥4周 HBsAg阳性、抗-HBc阳性者，糖皮质激素不论为中剂量(10~20 mg/d)还是高剂量(＞20 mg/d)
中风险 (HBV再激活的发生率1%~10%)	糖皮质激素治疗≥4周 HBsAg阳性、抗-HBc阳性者，糖皮质激素低剂量(＜10 mg/d) HBsAg阴性、抗-HBc阳性者，糖皮质激素不论为中剂量(10~20 mg/d)还是高剂量(＞20 mg/d)
低风险(HBV再激活的发生率＜1%)	AZA HBsAg阳性、抗-HBc阳性＜1% HBsAg阴性、抗-HBc阳性：风险远＜1% 糖皮质激素治疗≤1周 HBsAg阳性、抗-HBc阳性＜1% HBsAg阴性、抗-HBc阳性：风险远＜1% 糖皮质激素治疗≥4 周HBsAg阴性、抗-HBc阳性者，糖皮质激素低剂量(＜10 mg/d)

表 2 成人AIH患者的治疗方案(以60 kg为例)

周数	泼尼松(龙)(mg/d)	AZA(mg/d)
1	60(=1 mg/kg体质量)	不使用AZA
2	50	不使用AZA
3	40	50
4	30	50
5	25	100¹⁾
6	20	100¹⁾
7+8	15	100¹⁾
8+9	12.5	100¹⁾
从第10周起	10	100¹⁾
注：如第10周后转氨酶达到正常水平，则将泼尼松(龙)继续减量至7.5 mg/d，3个月后减量至5 mg/d，并根据患者的危险因素和应答情况，泼尼松(龙)继续逐步减量，通常每3~4个月减量1次。1)AZA的剂量按1~2 mg/kg体质量。

表 3 单纯性AIH的治疗

诱导阶段	维持阶段
激素	一旦获得生化缓解
泼尼松(龙)(20~40 mg/d) 或布地奈德(9 mg/d)	可尝试停用激素，改为单一AZA继续治疗每3~4个月进行实验室监测
AZA	持续生化缓解
检查TPMT，2周后增加AZA	持续24个月以上者，每4~6个月进行实验室监测
每1~2周进行实验室检查	可酌情考虑停止免疫抑制剂治疗(并非需要肝穿刺活检)
应答评估
4~8周评估应答情况
出现生化应答者：
在6个月内，泼尼松(龙)逐渐减量至5~10 mg/d (或布地奈德减量至3 mg/d)
维持使用AZA
未出现生化应答者：
重新诊断评估
考虑应用二线药物
