INT J LAB HEMATOL:常见β-地中海贫血突变特征的高凝状态

2017-04-12 MedSci MedSci原创

β-地中海贫血中的凝血活化是多因素的,最有可能是磷脂酰丝氨酸(PS)暴露于红细胞表面的结果。研究员检测了携带常见地中海突变的β-地中海贫血(BTT)患者中红细胞的PS暴露和促凝血活性的程度。

近日,来自埃及扎加齐克大学的研究人员报道了一项关于常见β-地中海贫血突变特征的高凝状态的研究,相关研究成果刊登于国际杂志INT J LAB HEMATOL上。

β-地中海贫血中的凝血活化是多因素的,最有可能是磷脂酰丝氨酸(PS)暴露于红细胞表面的结果。研究员检测了携带常见地中海突变的β-地中海贫血(BTT)患者中红细胞的PS暴露和促凝血活性的程度。

研究员研究了携带共同的地中海突变(β+n = 53和β0n = 27)的八十个BTT受试者和作为对照的六十个健康受试者。对他们的血浆凝血酶原片段1 + 2F1 + 2),红细胞膜上PS表达的百分比,修饰的凝血激酶产生试验(MTGT)和高岭土修饰的部分凝血激酶(MPTTK)的凝血时间进行了检测。

BTT受试者中β0组与β+组相比,膜联蛋白V阳性RBC和血浆F1 + 2的百分比有显着增加,MTGT显著降低。 与对照组相比BTT受试者的MPTTK明显缩短 ,但在BTT受试者中β0组与β+组无明显差异。膜联蛋白V阳性的红细胞的百分比与血红蛋白水平,MTGTMPTTK呈负相关,与血浆F1 + 2呈正相关。

BTT受试者可能具有高凝状态的风险,特别是β0基因型。检测红细胞和血浆F1 + 2PS暴露有利于评估高凝状态。
