We analyzed the outcomes of 44 patients with paroxysmal nocturnal hemoglobinuria (PNH) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) (haploidentical [haplo]-donors, 25; matched sibling donors [MSDs], 15; and matched unrelated donors, 4) between July 2007 and May 2018. All patients achieved successful donor engraftment. The median time was 12 days (range, 7 to 26) for myeloid engraftment and 13 days (range, 11 to 75) for platelets. The cumulative incidences were 15.91% and 2.27% for grades II to IV and grades III to IV acute graft-versus-host disease (GVHD), respectively, with a median follow-up time of 36 months (range, 4 to 132). The cumulative incidences were 26.73% for chronic GVHD and 9.70% for moderate to severe chronic GVHD. No patients relapsed. The probabilities of 3-year overall survival (OS) and GVHD-free, failure-free survival (GFFS) were 90.4% ± 4.6% and 85.6% ± 5.4%, respectively. The 3-year OS rates of the haplo-donor and MSD groups were 86.5% ± 7.3% versus 93.3% ± 6.4% (P = .520). The 3-year GFFS rates of the haplo-donor and MSD groups were 78.3% ± 8.6% versus 92.9% ± 6.9% (P = .250). The preliminary results indicated that allo-HSCT is a feasible option for patients with PNH; however, this should not be considered as a first-choice therapy, because the results seemed to only suggest rather than confirm that haplo-HSCT and MSD-HSCT exerted similar therapeutic efficacies.
我们分析了 2007 年 7 月至 2018 年 5 月期间 44 例阵发性睡眠性血红蛋白尿症（PNH）患者接受异基因造血干细胞移植（allo-HSCT）（单倍体[haplo]-供体 25 例，匹配的同胞供体 15 例，匹配的无关供体 4 例）的结果。所有患者均成功获得供体植入。髓系植入的中位时间为 12 天（范围为 7 至 26 天），血小板植入的中位时间为 13 天（范围为 11 至 75 天）。Ⅱ至Ⅳ级和Ⅲ至Ⅳ级急性移植物抗宿主病（GVHD）的累积发生率分别为 15.91%和 2.27%，中位随访时间为 36 个月（范围为 4 至 132 个月）。慢性 GVHD 的累积发生率为 26.73%，中重度慢性 GVHD 的累积发生率为 9.70%。无患者复发。3 年总生存率（OS）和无 GVHD、无失败生存（GFFS）的累积发生率分别为 90.4%±4.6%和 85.6%±5.4%。haplo 供体和 MSD 组的 3 年 OS 率分别为 86.5%±7.3%和 93.3%±6.4%（P=0.520）。haplo 供体和 MSD 组的 3 年 GFFS 率分别为 78.3%±8.6%和 92.9%±6.9%（P=0.250）。初步结果表明，allo-HSCT 是 PNH 患者可行的选择；然而，这不应该被视为首选治疗，因为结果似乎只是表明而不是证实haplo-HSCT 和 MSD-HSCT 具有相似的治疗效果。
