造血干细胞移植术(HSCT)给许多血液病患者带来了延长生存期的可能,但移植术后患者往往因免疫功能低下而并发巨细胞病毒性视网膜炎(CMVR)。更昔洛韦玻璃体腔注射(IVG)是该病的主要治疗手段之一。因HSCT术后CMVR的治疗和随访尚缺乏标准化共识或指南,现存的IVG方案在给药剂量和给药频率上尚存在较大差异。基于房水病毒载量和细胞因子监测的大剂量IVG治疗和随访方案开始被应用于临床,并被证实可显著缩短治疗时长并减少注药次数。IVG造成视网膜毒性的病例报道十分罕见,其治疗HSCT术后CMVR是安全且有效的,但安全剂量范围尚需探索。本文从更昔洛韦的作用机制、系统性应用存在的问题、玻璃体腔注射的治疗方案、玻璃体腔注射的视网膜毒性几个方面就IVG治疗HSCT术后并发CMVR的研究进展进行综述。
Hematopoietic stem cell transplantation (HSCT) brings the possibility to prolong survival for patients with different types of hematological diseases, but patients may be complicated with cytomegalovirus retinitis (CMVR) due to immunocompromised state.Intravitreous injection of ganciclovir (IVG) is a major treatment in CMVR after HSCT, but there are significant differences in the dosage and frequency among existing IVG protocols due to lack of standardized consensus or guidelines.High-dose IVG therapy and a follow-up plan based on aqueous humor virus load and cytokine monitoring have been applied in clinical practice, and it has been reported to shorten treatment duration and reduce number of injections.Reports of retinal toxicity caused by IVG are rare, and more exploration is needed to determine the safe dose range of IVG.This article reviewed the advances in IVG treatment of CMVR after HSCT focusing on the acting mechanism of ganciclovir, the problems in systematic application, the treatment plan involving intravitreal injection, and the retinal toxicity of intravitreal injection.
