Abstract
OBJECTIVE: To examine whether there was an association between epithelial neutrophil activating peptide 78 (ENA-78), interferon-inducible protein 10 (IP-10), vascular endothelial growth factor (VEGF) polymorphism and Chinese patients with idiopathic pulmonary fibrosis (IPF). METHODS: Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were performed to analyze the gene polymorphisms of ENA-78 (-156G/C), IP-10 (-1596C/T) and VEGF (+405G/C) in 60 IPF patients and 60 controls with trauma or bone fracture matched in age, gender and smoking status. RESULTS: The distribution of carrying GC + CC genotype frequency (20.0%) and C allele frequency (12.7%) for ENA-78 in IPF patients was significantly higher than that in healthy controls [6.7% (P = 0.032) and 3.3% (P = 0.008), respectively], the relative risk of suffering from IPF of -156C allele gene carrier significantly increased (OR = 4.23, 95%CI: 1.35-13.20). The distribution of carrying CT + TT genotype frequency (10.0%) and T allele frequency (5.8%) for IP-10 in IPF patients was significantly lower than that in healthy controls [26.7% (P = 0.018) and 14.2% (P = 0.031), respectively], the relative risk of suffering from IPF of -1596T allele gene carrier decreased (OR = 0.38, 95%CI: 0.15-0.95). No association was found between VEGF (+405G/C) polymorphism and IPF. CONCLUSIONS: -156C allele for ENA-78 may be a risk factor of IPF and -1596T allele for IP-10 a beneficial factor of IPF. The VEGF (+405G/C) gene polymorphism has no effect upon the predisposition to IPF.
