Abstract
Background and Objectives： the nasal cavity and occur on both infectious and noninfectious basis, and genetic etiology is suspected in the development of nasal polyps. 5-Lipoxygenase is the first enzyme committed in the metabolic pathway leading to the intracellular synthesis of leukotrienes. Some studies have shown that leuko-trienes were significantly higher in nasal polyps from aspirin-sensitive asthmatics than in nasal polyps from aspirin-tolerant asthmatics and normal nasal mucosa. The purpose of the present study is to evaluate whether genetic polymorphism of the core promoter region of the 5-lipoxygenase gene contributes to the development of nasal polyps. Subjects and Method：This study was conducted in 97 nasal polyp patients associated with chronic sinusitis and 92 healthy controls. Genetic polymorphisms of 5-lipoxygenase gene promoter were genot Results：There were no significant differences between the 5-lipoxygenase gene promoter polymorphisms in nasal polyp patients with chronic sinusitis and those in healthy controls (p= 0.76). In the nasal polyp patients associated with chronic sinusitis, the frequencies of 6-bp deletion were lower than those of healthy controls (OR, 0.88 95% CI, 0.48- 1.60), but there was no statistical significance (p= 0.67). The frequencies of 6-bp addition were higher than those of healthy controls (OR, 1.96; 95% CI, 0.33- 10.6), but no significant diference was found (p= 0.68). Conclusion：We concluded that 5-lipoxygenase gene promoter polymorphism did not show genetic predisposition with regard to nasal polyps in the Korean population. (Korean J Otolaryngol 2007 ;50 :310-3)
