Abstract
BACKGROUND: Rosacea is a chronic disease that is characterized by facial skin inflammation and vascular abnormality. Vascular endothelial growth factor (VEGF) is a potent mediator of vascular permeability and inflammation that might play a role in the pathogenesis of rosacea. OBJECTIVE: This study aimed to determine the association between VEGF gene polymorphisms and rosacea. METHODS: A case-control study design was used to compare 100 patients with rosacea and 100 age- and gender-matched control subjects in terms of VEGF polymorphisms based on polymerase chain reaction and the serum level of VEGF and VEGF receptors based on enzyme-linked immunosorbent assay. RESULTS: Heterozygous and homozygous +405C/G polymorphism of the VEGF gene was observed to increase the risk of rosacea 1.7-fold (95% confidence interval 1.2-4.2) and 2.3-fold (95% confidence interval 1.2-4.2), respectively. There was a significant positive correlation between the severity of rosacea and +405C/G polymorphism of the VEGF gene in patients with erythematotelangiectatic rosacea. LIMITATIONS: Serum VEGF and VEGF receptor levels were measured in the limited number of patients. CONCLUSION: The present findings indicate that +405C/G polymorphism of the VEGF gene increases the risk of rosacea.
