摘要
目的:探索单倍体造血干细胞移植联合脐血输注治疗儿童再生障碍性贫血的疗效及安全性。方法:纳入河南中医药大学人民医院2021年1月1日至2023年9月15日接受脐血联合单倍体造血干细胞移植治疗的9例再生障碍性贫血患儿,中位年龄为11(2-13)岁,中位随访18(7.5-21)个月,回顾性分析其临床资料,对植入情况、GVHD发生率、感染等并发症及生存进行分析。结果:9例患儿全部成功植入。中性粒细胞和血小板植入中位时间分别为11.11±1.27 d、12.44±3.36 d。1例发生Ⅰ度急性消化道移植物抗宿主病,治疗后好转,后期该例患者发生浅表性胃炎及慢性消化道移植物抗宿主病,目前临床随访中。无一例患儿发生Ⅱ-Ⅳ度急性移植物抗宿主病。出血性膀胱炎3例,CMV感染5例,细菌及真菌感染5例,经对症治疗后好转。9例患儿移植后1个月内均表现为完全供者嵌合,随访两年,9名患儿全部生存,未出现复发或发生Ⅱ-Ⅳ度移植物抗宿主病,无移植相关死亡患儿。结论:单倍体造血干细胞移植联合脐血输注治疗儿童再生障碍性贫血时GVHD发生率低,程度轻,疗效显著,可以作为无HLA全相合配型患儿的一种治疗方案。
Objective:To explore the efficacy and safety of haploidentical hematopoietic stem cell transplantation combined with umbilical cord blood infusion for the treatment of aplastic anaemia in children.Methods:Nine cases of children with aplastic anaemia treated with umbilical cord blood combined with haploidentical hematopoietic stem cell transplantation at the People′s Hospital of Henan University of Chinese Medicine from January 1,2021 to September 15,2023 with a median age of 11(2-13)years and a median follow up of 18(7.5-21)months were included,and the clinical data were retrospectively analyzed.Hematopoiesis reconstitution,the incidence of graft-versus-host disease(GVHD),infections and survival of the patients were analyzed.Results:All 9 children were successfully implanted.The median time to neutrophil and platelet implantation was 11.11±1.27 d and 12.44±3.36 d,respectively.One case developed acute gastrointestinal GVHD of degree I,which was improved after treatment,and the patient developed superficial gastritis and chronic gastrointestinal GVHD at a later stage,which is currently under clinical follow-up.Acute GVHD of II-IV degree was 0%.Hemorrhagic cystitis in 3 cases,CMV infection in 5 cases and bacterial and fungal infections in 5 cases improved with symptomatic treatment.All 9 children demonstrated complete donor chimerism within 1 month after transplantation,at two years of follow-up,all nine children survived without recurrence or development of grade II-IV GVHD,and there were no children with transplant-related deaths.Conclusion:Haploidentical hematopoietic stem cell transplantation combined with umbilical cord blood transfusion for aplastic anaemia in children has a low incidence and mild degree of GVHD,with significant efficacy,and can be used as a therapeutic option for children without an HLA full donor chimeric match.
