The antibody specificity was identified as anti-Ce using panel-cell, and was IgG antibody. The anti-Ce antibody had both anti-C and anti-e activity. It is very difficult to find a Ce antigen negative blood for transfusion. The compatible donors rate is very low, only 2%-3%.展开更多
目的:分析1例RhCCee表型输血患者血清中产生抗-C同种抗体的特征与潜在原因.方法:采用微柱凝胶卡法检测患者Rh血型抗原、血清不规则抗体与鉴定等;PCR-SSP法检测Rh血型基因型,基因测序分析Rh血型基因的突变点.结果:该患者血清不规则抗体...目的:分析1例RhCCee表型输血患者血清中产生抗-C同种抗体的特征与潜在原因.方法:采用微柱凝胶卡法检测患者Rh血型抗原、血清不规则抗体与鉴定等;PCR-SSP法检测Rh血型基因型,基因测序分析Rh血型基因的突变点.结果:该患者血清不规则抗体筛查阳性,鉴定结果为抗-C;微柱凝胶卡法RhCE表型呈混合视野,红细胞样本洗涤3次热放散后RhCE表型鉴定为CCee;PCR-SSP法检测Rh基因型为CCee,与放散后血清学结果一致;直接抗人球蛋白试验(DAT)阳性(++),R h C E表型同型(CCee)供者红细胞交叉配血主次侧均凝集(++),但R h抗原不匹配(ccEe)供者红细胞交叉配血主侧无凝集.基因测序结果证实该患者等位基因为RhCE*02、RhCE*Ce,Rh血型基因型为CCee;外显子1和外显子2点突变分别为:c.48G>C、c.150C>T、c.178C>A、c.201A>G、c.203A>G、c.307C>T,无新发点突变.结论:RhCCee表型输血患者产生抗-C抗体与Rh血型基因新发点突变无关,可能与该患者机体自身免疫功能状况或结构变异相关.展开更多
