Autoimmune liver diseases (AILDs) can recur following liver transplantation (LT) despite immunosuppressive therapy, with implications for graft survival. Although the evidence is not robust, disease recurrence seems to occur in the presence of less intense and/or steroid-free immunosuppression (IS) in particular in the case of autoimmune hepatitis (AIH). The main risk factor for AIH recurrence is the severity of disease activity in the explant and potential donor/recipient human leukocyte antigen D-related 3 (DR3) mismatch. The treatment for AIH recurrence includes reintroduction or increase in the dose of steroids with or without the addition of azathioprine. T cell-mediated rejection episodes are also more common in AILD. Steroid withdrawal is the common practice in LT for non-AILD, eliminating the risks associated with longterm exposure to steroids. In AILD, maintenance of steroids at a low dose in the long term may reduce the risk of disease recurrence and rejection. This strategy is safe when there is vigilance for steroid-related adverse effects. Alternatively, identifying patients who are at the greatest risk for disease recurrence and who would benefit from intensified IS might be an option.
自身免疫性肝病(AILD)在肝移植(LT)后尽管进行免疫抑制治疗仍可能复发,这对移植物的存活率有影响。尽管证据并不充分,但疾病复发似乎在免疫抑制(IS)程度较轻和/或无类固醇的情况下发生,尤其是在自身免疫性肝炎(AIH)的情况下。AIH 复发的主要危险因素是供体/受者人类白细胞抗原 DR3 相关 3(DR3)错配和肝移植物中疾病活动的严重程度。AIH 复发的治疗包括重新引入或增加类固醇剂量,同时添加硫唑嘌呤。T 细胞介导的排斥反应在 AILD 中也更为常见。非 AILD 的 LT 中常规采用撤停类固醇,以消除长期接触类固醇相关的风险。在 AILD 中,长期低剂量维持类固醇可能降低疾病复发和排斥的风险。当警惕类固醇相关不良反应时,该策略是安全的。或者,识别出最有可能复发且受益于强化 IS 的患者可能是一种选择。
