Abstract

Background and Objective: The current study aimed at assessing the relationship between gastritis and peptic ulcer susceptibility and inflammation-related gene polymorphisms in Iranian patients. Gastritis and peptic ulcer are common medical complications with serious outcomes on the quality of life. Inflammatory responses of gastric mucosa are associated with helicobacter pylori, but most infected patients remain asymptomatic. There is strong evidence that inflammatory response is a major part of its etiology.
Methods: The current case-control study aimed at examining genetic polymorphisms in inflammatory cytokines interleukin (IL)-4, and IL-10 using polymerase chain reaction-variable number tandem reaped (PCR-VNTR) and PCR-restriction fragment length polymorphism (RFLP) methods, respectively in 603 genotyped patients admitted to Mohammadi Hospital in Bandar Abbas, Iran (198 patients with gastritis, 84 with peptic ulcer, and 321 patients as controls).
Results: No significant associations were detected in genotype and allele frequencies of IL-10 and IL-4 between the case (with gastritis and peptic ulcer) and control groups.
Conclusion: In conclusion, the results of the analyses suggested that these polymorphisms may not predispose the carriers to gastritis and peptic ulcer development.
