Abstract:
OBJECTIVETo 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.
METHODSSix 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.
