['The aim of this study was to investigate the association of Glycoprotein IIb (GPIIb) human platelet antigen-3 (HPA-3) a/b polymorphism with end-stage renal disease (ESRD) on hemodialysis (HD) and native Arteriovenous fistula (AVF) thrombosis.', 'The polymorphism in the GPIIb subunit of the receptor HPA-3 (a and b alleles) was identified by polymerase chain reaction with sequence-specific primers (PCR-SSP) in 145 HD patients and 120 healthy controls from a Chinese Han population. The HD patients were classified into two groups: G1 and G2. G1 included 65 HD patients presented at least one AVF thrombosis episode and G2 included 80 HD patients without any episode of AVF thrombosis.', 'There were no significant differences in either HPA-3 a/b genotypes (aa, ab, and bb) frequency distribution (p = 0.396) or allele (a and b) frequency distribution (p = 0.146) between HD patients and control groups. However, there were significant differences in both HPA-3 a/b genotypes (aa, ab, and bb) distribution (χ(2) = 6.127, p = 0.047) and allele (a and b) frequency distribution (χ(2) = 5.954, p = 0.015) between G1 and G2. The relative risk of native AVF dysfunction in ab + bb patients compared with that of aa patients was 2.31 (95% confidence interval: 1.18-4.52).'] Is platelet glycoprotein IIb HPA-3 a/b polymorphism associated with native arteriovenous fistula thrombosis in chronic hemodialysis patients?
