Febrile non-hemolytic transfusion reaction (FNHTR) is the most common type of transfusion reactions, and it could be reduced by transfusing patients with leukocyte-poor blood products. However, FNHTR still occur in certain patients transfused with leukocyte-poor red blood cell (LPR) products. It is examined whether human platelet antigen (HPA) could be a potential membrane antigen that plays a role in FNHTR.
A total of 120 inpatient subjects who transfused with LPR (60 in FNHTR group, 60 in control group) were typed for HPA-2, HPA-3, and HPA-15 using sequence specific primer-polymerase chain reaction (SSP-PCR) and electrophoresis.
HPA-2 unmatched rate between donors and patients in FNHTR group was 18%, and only 3% unmatched rate was observed in control group (p=0.0082). FNHTR group was further classified according to the imputability. There was a significant difference (p=0.0041) between FNHTR (probable imputability, infection) group and control group, and more significant difference (p=0.0008) was seen between FNHTR (probable imputability, febrile neutropenia) group and control group.
Those results indicated that HPA-2 might play roles on inducing FNHTR in patients suffering from infectious diseases and febrile neutropenia. HPA-2 genotyping between donors and recipients might be worth integrating in pre-transfusion testing to increase transfusion safety.
发热非溶血性输血反应(FNHTR)是最常见的输血反应类型,可以通过输注白细胞减少的血液制品来减少。然而,某些输注白细胞减少的红细胞(LPR)产品的患者仍会发生 FNHTR。研究人员检查了人类血小板抗原(HPA)是否可以作为膜抗原在 FNHTR 中发挥作用。
采用序列特异性引物-聚合酶链反应(SSP-PCR)和电泳法对 120 例输注 LPR 的住院患者(FNHTR 组 60 例,对照组 60 例)进行 HPA-2、HPA-3 和 HPA-15 分型。
FNHTR 组供者与患者之间 HPA-2 不匹配率为 18%,而对照组仅为 3%(p=0.0082)。根据归因可能性将 FNHTR 组进一步分类。FNHTR(可能归因于感染)组与对照组之间存在显著差异(p=0.0041),FNHTR(可能归因于发热性中性粒细胞减少症)组与对照组之间存在更显著差异(p=0.0008)。
这些结果表明 HPA-2 可能在诱导感染性疾病和发热性中性粒细胞减少症患者发生 FNHTR 中发挥作用。在输血前检测中对供者和受者之间的 HPA-2 基因分型可能值得整合,以提高输血安全性。
