Abstract

Abstract: Recently, human platelet antigens (HPAs) polymorphisms are found to play a role in susceptibility to hepatitis C virus (HCV) infection and fibrosis progression. The aim of the current study was to evaluate the possible association between the HPAs polymorphisms with liver fibrosis progression in HCV patients. HPAs polymorphisms genotyping was performed in HCV patients (n = 71) by Sequence‐specific primers‐polymerase chain reaction. Fibrosis progression was evaluated using the Metavir scoring system and liver biopsy, and the patients were assigned to two groups, namely, G1 (n = 35) that included patients with F1 (portal fibrosis without septa) or F2 (few septa) and G2 (n = 36) that comprised patients with F3 (numerous septa) or F4 (cirrhosis). The data analyses were performed using Pearson's χ 2 test. The genotype frequency of HPA‐3ab was significantly higher in G1 patients than in G2 patients ( P = 0.015). No statistically significant differences were found between the patient groups (G1 and G2) regarding the distributions of the allelic and genotypic frequencies of the HPA‐1, ‐2, ‐4, ‐5, and ‐15 systems. Multivariate logistic regression showed an independent association between the genotype HPA‐3aa/BB and severe fibrosis (F3‐F4), when compared with genotype HPA‐3ab, independent of the viral genotype, high alanine transaminase, sex, age, time of infection, diabetes, and high cholesterol as risk factors. The present study suggested that the HPA‐3ab genotype could be noticed as a potential protecting factor against hepatic fibrosis. Therefore, the antigenic variation of integrins might be considered as a part of the coordinated inflammatory process involved in the progression of liver fibrosis. Highlight: SNP polymorphism in the antigenic expression of integrins might play role in the inflammation process leads to the developing liver fibrosis.This study suggested a possible association between the HPA‐3aa/bb and the progression of liver fibrosis In Iranian HCV patients. Thus, antigenic variation of integrins could be considered as a part of the coordinated inflammatory process involved in the development of liver fibrosis.
