摘要
目的对本院3例ABO血型次侧不合肝肾移植后并发的过客淋巴细胞综合征(PLS)病例的临床特征、血清学特征、输血方案及治疗进行总结,为临床全面了解和认识该疾病,特别是早期识别及治疗提供指导。方法通过采集患者基本信息和移植后出现同型血交叉配血不合的时间,观察患者皮肤黄染情况,检测血红蛋白(Hb)及其他溶血指标、输血前后血型血清学等进行诊断分析;通过采集经免疫和输血治疗后的临床转归信息对PLS诊断及治疗效果进行分析。结果3例患者ABO血型次侧不合肝肾移植术后出现Hb下降及溶血表现、同型血交叉配血不相合,经血清学试验证实存在IgG抗-A、抗-B;经免疫抑制、血浆置换等对症治疗及改变输血策略后,输血有效,溶血好转,抗体逐渐消失。结论ABO血型次侧不合肝肾移植病例,需定期做ABO血型抗体和不规则抗体筛查及直接抗人球蛋白试验,以便能早期发现PLS;同型交叉配血不相合时应及时进行PLS相关的系列实验室检测,以便及时诊断及调整包括输血策略在内的治疗方案。
Objective To summarize the clinical features,serological features,blood transfusion protocols and treatment of 3 cases of passenger lymphocyte syndrome(PLS)after ABO-incompatibility liver and renal transplantation in our hospital,in order to provide guidance for comprehensive clinical understanding and recognition of this disease,especially early recognition and treatment.Methods By collecting the basic information of the patients and the time of cross-matching incompatibility of homologous blood after transplantation,observing the skin yellow staining,detecting hemoglobin value and other hemolysis indexes,and blood group serological detection results before and after transfusion,the diagnosis and analysis were performed.The diagnosis and treatment effect of PLS were analyzed by collecting the clinical outcome information after immunization and blood transfusion.Results Three cases of ABO-incompatible liver transplantation showed decreased hemoglobin and hemolysis,incompatible cross-matching of homologous blood,and anti-A and anti-B IgG antibodies were confirmed by serological test.After treatment such as immunosuppression and plasma exchange,blood transfusion was effective,hemolysis was improved,and antibodies gradually disappeared.Conclusion ABO blood group antibody screening,unexpected antibody screening and direct antiglobulin test(DAT)should be performed regularly for ABO-incompatible liver and renal transplantation cases,in order to detect the PLS early.A series of laboratory tests related to PLS should be performed in time to diagnose and adjust the treatment plan,including transfusion strategy,when homologous cross-matching is incompatible.
