Abstract
OBJECTIVE: To study the distribution of IL-10 gene polymorphisms in patients with gastroduodenal diseases in Hubei Han population and their association with helicobacter pylori (Hp) infection. METHODS: Six hundred and five patients with gastroduodenal diseases (220 gastric cancer, 196 chronic gastritis and 189 gastroduodenal ulcer) and 624 healthy controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for IL-10 -1082, -819, -592 gene polymorphisms. Hp infection status was determined by ELISA. RESULTS: (1) There was significant difference of IL-10 -1082 AG+GG genotypes between gastric cancer group and gastric cancer-free and healthy control groups (P<0.05). (2) There was no significant difference of IL-10 -592 and IL-10 -819 gene polymorphisms among gastric cancer, gastric cancer-free and healthy control groups (P>0.05). (3) The frequency of IL-10 -1082 AG+GG genotypes in the Hp positive gastric cancer patients was significantly higher than that of control groups (P<0.05). CONCLUSIONS: (1) Genotypes AG+GG of IL-10 -1082 were associated with gastric cancer in Hubei Han population. (2) The IL-10 -1082 AG+GG genotypes were associated with Hp infection in patients with gastric cancer.
