Objective: To observe the efficacy and safety of sirolimus combined with calcineurin inhibitor (CNI) in the treatment of glucocorticoid resistant/dependent extensive chronic graft-versus-host disease (cGVHD) . Methods: A total of 27 patients with steroid-resistant/steroid-dependent extensive cGVHD from November 2015 to January 2019 were enrolled and given sirolimus capsules combined with cyclosporine or tacrolimus to observe the clinical efficacy and adverse events. Results: The median duration of medication was 14.2 months and the mean duration was 16.7 months. The median follow-up time was 20.1 months (12.9-46.1 months) . Following the 6-month follow-up, 3 cases achieved complete response (CR) and 12 cases partial response (PR) . The overall response rate (ORR) was 55.6% ; for progression-free survival (PFS) , PFS-6 reached 88.9% (24/27) , and for overall survival (OS) , OS-6 was 100% . At the 1-year follow-up, there were 5 cases of CR and 11 cases of PR, ORR was 59.3% , PFS-12 reached 62.9% (17/27) , and OS-12 was 100% . The subgroup analysis found that the program was more effective for cGVHD in male donors and the target organ analysis had an advantage in the treatment of oral cavity, skin, and liver rejection. Adverse events were observed: hyperlipidemia 11.1% , oral ulcer 7.4% , fungal infection 11.1% , liver injury 3.7% , renal insufficiency 0, and no new CMV and EB viremia. Conclusion: Sirolimus combined with calcineurin inhibitors is effective in treating steroid-resistant/steroid-dependent extensive cGVHD, especially because adverse reactions (renal toxicity, CMV, EBV infection) are low in number, which is suitable for long-term treatment of cGVHD.
目的： 观察西罗莫司联合钙调磷酸酶抑制剂（CNI）治疗糖皮质激素耐药/依赖广泛型慢性移植物抗宿主病（cGVHD）的疗效和安全性。 方法： 选择糖皮质激素治疗耐药/依赖的cGVHD患者，给予西罗莫司联合环孢素A/他克莫司治疗。 结果： ①入组患者27例，男17例，女10例，中位年龄36（19～56）岁。急性髓系白血病13例，急性淋巴细胞白血病4例，慢性髓性白血病4例，骨髓增生异常综合征3例，淋巴瘤1例，再生障碍性贫血1例，阵发性睡眠性血红蛋白尿症1例。HLA全相合同胞或亲缘供者移植14例，HLA全相合无关供者移植2例，HLA不全相合同胞或亲缘供者移植11例。②患者中位服药时间为14.2个月，中位随访时间20.1（12.9～46.1）个月。③随访6个月时，完全缓解（CR）3例，部分缓解（PR）12例，总反应率（ORR）为55.6％，6个月时无病生存率（PFS-6）、总生存率（OS-6）分别为88.9％（24/27）、100％。④随访12个月时，CR 5例，PR 11例，ORR为59.3％，PFS-12为62.9％（17/27），OS-12为100％。⑤亚组分析发现该方案对男供者的cGVHD更有效，对治疗口腔、皮肤、肝脏cGVHD疗效较好。⑥不良反应：新发高脂血症3例，血糖升高1例，腹胀/腹泻4例，口腔溃疡2例，血尿1例，药物性肝损伤1例，细菌感染3例，真菌感染3例，带状疱疹2例，均为1～2级，无新增巨细胞病毒、EB病毒感染。 结论： 西罗莫司联合CNI治疗糖皮质激素耐药/依赖广泛型cGVHD的疗效及安全性较好，适合cGVHD的长期治疗。.
