摘要: 目的 对ABO血型次要不合(B供A1B)异基因造血干细胞移植(allogeneic hematopoietic stem cell transplantation, allo-HSCT)术后并发过客淋巴细胞综合征(passenger lymphocyte syndrome, PLS)A1抗原丢失病例的临床特征、血清学特征、基因型特征和多学科分层管理策略进行探讨,同时结合文献回顾为临床早期识别与治疗提供依据。方法 采用微柱凝胶法和试管法检测患儿ABO血型并采用Sanger测序验证血型基因型,根据患儿造血干细胞移植术前后胆红素、乳酸脱氢酶、血红蛋白和网织红细胞百分比变化来评估溶血情况。结果 移植后患儿血红蛋白持续下降,网织红细胞百分比、胆红素、乳酸脱氢酶水平升高,提示溶血。ABO血型正反定型不一致;基因测序显示ABO*A1.02/ABO*B.01,但血清学检测A1抗原丢失。结论 本研究为1例allo-HSCT后并发PLS伴A1抗原短暂丢失的病例报道,提示PLS的诊断需结合ABO血型正反定型矛盾及溶血实验室证据以及PLS的临床异质性,进一步强调了ABO血型监测在多学科协作中的价值。

Abstract: Objective Investigation of clinical, serological, and genotypic characteristics and multidisciplinary tiered management strategies in a case of A1 antigen loss resulting from passenger lymphocyte syndrome (PLS) following ABO minor-incompatible (B to A1B) allogeneic hematopoietic stem cell transplantation (allo-HSCT), combined with literature review to provide a reference for early clinical identification and treatment. Methods The patient's ABO blood group was determined using both microcolumn gel and tube methods, with genotyping confirmed by Sanger sequencing. Hemolysis was assessed by monitoring pre- and post-transplant changes in total bilirubin, lactate dehydrogenase (LDH), hemoglobin levels, and reticulocyte percentage. Results Following transplantation, the patient exhibited progressive hemoglobin decline, elevated reticulocyte percentage, hyperbilirubinemia, and increased LDH levels—findings indicating hemolysis. Discrepancies were noted between ABO forward and reverse typing. Genetic sequencing confirmed an ABO*A1.02/ABO*B.01 genotype; however, serological testing revealed a transient loss of A1 antigen expression. Conclusion This case report of transient A1 antigen loss with passenger lymphocyte syndrome (PLS) following allo-HSCT demonstrates that PLS diagnosis requires the combination of ABO forward/reverse grouping discrepancy, hemolytic laboratory evidence, and recognition of PLS clinical heterogeneity, further highlighting the value of ABO blood group monitoring in multidisciplinary collaboration.
