Abstract
AIM: To compare serum levels of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in patients with peptic ulcer (PU) caused by different strains of Helicobacter pylori (H. pylori).
METHODS: Ninety-four patients with gastroscopically diagnosed PU were randomly selected. H. pylori infection status was detected by endoscopic gastric mucosa biopsy and rapid urease test. Antibodies against various H. pylori proteins (CagA, VacA, UreB, UreA) were detected by immunological method. The contents of serum IL-10 and TNF-α were determined in all subjects.
RESULTS: The H. pylori positive rate was 89.4% (84/94) in PU, 66.7% (56/84) in duodenal ulcer (DU) and 33.3% (28/84) in gastric ulcer (GU). Sixty-four cases (44 DU and 20 GU) were infected by typeⅠH. pylori and 20 cases (12 DU and 8 GU) were infected by type Ⅱ H. pylori. There was no significant difference in serum level of IL-10 between typeⅠH. pylori infection group and type Ⅱ H. pylori infection group (P > 0.05). Serum level of IL-10 was significantly higher in typeⅠH. pylori infection group than in H. pylori negative group (P < 0.05), although there was no significant difference between Type Ⅱ H. pylori infection group and H. pylori negative group (P > 0.05) or between DU and GU group with either typeⅠor type II H. pylori infection. Serum TNF-α was significantly higher in typeⅠor Ⅱ H. pylori infection group than in H. pylori negative group (P < 0.05 for both), in typeⅠH. pylori infection group than in type Ⅱ H. pylori infection group, or in DU group than in GU group with typeⅠH. pylori infection (P < 0.05), but showed no significant difference between DU group and GU group with type Ⅱ H. pylori infection.
CONCLUSION: TypeⅠH. pylori infection is a major pathogenic factor of PU. Serum IL-10 in patients with typeⅠH. pylori infection was increased obviously, but showed no significant correlation with the type of H. pylori infection or ulcer location. Serum TNF-α was increased obviously in patients with typesⅠand Ⅱ H. pylori infection, especially the former, and was obviously higher in DU patients than in GU patients with typeⅠH. pylori infection.
