Among severely immunosuppressed patients resistant or refractory cytomegalovirus (CMV) retinitis is not uncommon, and is potentially blinding in the affected eye. Immunotherapy using CMV-specific cytotoxic T lymphocytes (CTLs) is an emerging and promising alternative for the control of resistant or refractory CMV retinitis. However, highly purified CMV-CTLs are still not available in the majority of medical institutions in China because the generation of CMV-CTLs is labor intensive, time-consuming and expensive.
This letter describes the clinical responses to a simplified CMV-CTL immunotherapy aimed at controlling drug-resistant CMV retinitis in two immunodeficient patients.
Our cases suggest that the simplified CMV-CTL immunotherapy offers a highly efficient and low-cost solution to drug-resistant CMV retinitis. This immunotherapy strategy targeting drug-resistant CMV retinitis is likely to be cost-effective in the context of a specific patient population.
在严重免疫抑制的患者中,出现对抗病毒药物耐药或难治性巨细胞病毒(CMV)视网膜炎并不罕见,而且可能会导致受影响的眼睛失明。使用 CMV 特异性细胞毒性 T 淋巴细胞(CTL)的免疫疗法是一种新兴的、有前途的方法,可以控制耐药或难治性 CMV 视网膜炎。然而,由于 CMV-CTL 的产生劳动强度大、耗时且昂贵,因此在中国的大多数医疗机构中仍然无法获得高度纯化的 CMV-CTL。
本信函描述了针对两名免疫缺陷患者的耐药性 CMV 视网膜炎,采用简化的 CMV-CTL 免疫疗法的临床反应。
我们的病例表明,简化的 CMV-CTL 免疫疗法为耐药性 CMV 视网膜炎提供了一种高效且低成本的解决方案。针对耐药性 CMV 视网膜炎的这种免疫治疗策略,在特定的患者人群中可能具有成本效益。
