镰状细胞病同种异体免疫的频率:喀麦隆杜阿拉拉昆蒂 尼医院患者的病例
摘要
相比,同种异体免疫的镰状细胞病(SCD)患者的生存率似乎更差。因此,为了有助于SCD患者的管理和改善输血过程,
我们旨在确定SCD患者同种异体免疫的频率。为了实现这项研究,我们在喀麦隆杜阿拉的一家医院进行了一项横断面研
究。方法:从采集的血液样本中制备血浆,根据凝胶上的迁移情况进行电泳;确定电泳类型。血型ABO/Rh。电泳后,根
据获得的结果,丢弃非纯合子(SS)和杂合子镰状细胞性贫血(AS)。使用间接抗人球蛋白试验检查不规则凝集素。使
用Statview统计软件对不同参与者的临床和生物学特征进行研究和分析。结果:我们获得了104名镰状细胞患者,其中55%
的RAI阳性,平均输血7.35。还有83名患者为纯合型镰状细胞贫血,平均年龄15.75岁(1至52岁)。获得的结果表明,纯
合型镰状细胞患者的输血次数随着年龄的增长而增加,并且纯合型镰刀状细胞患者比杂合型患者接受了更多的输血。也
可以说,这些患者的同种异体免疫源于接受的不完全兼容的多次输血,并影响更多的儿童(1-15岁),他们约占总人口的
53.85%。我们获得的结果表明,未来,镰状细胞患者将很难找到适合治疗的血液,这是一个真正的问题,因为输血是喀麦
隆镰状细胞贫血患者的主要护理标准。缺乏治疗可能导致患者死亡。为了帮助减少同种异体免疫,在所有红细胞系统中进
行广泛的相容性试验,并定期筛查不规则凝集素的存在,可能会降低同种异体免疫的频率。
