Vitamin C modified relation between gastric cancer and Helicobacter pylori
Scientists showed that vitamin C modified the relationship between gastric cancer and Helicobacter pylori.
"A hospital-based case-control study of 295 cases with histologically confirmed gastric cancer and age and sex-matched controls was conducted to evaluate the effect of dietary vitamin C intake upon the relation between H. pylori infection and gastric cancer in Korea in 1997-1998. Anti-H. pylori IgG was detected by ELISA," researchers in South Korea reported.
To explain their methodology, D.S. Kim and colleagues from Seoul National University replied, "A food frequency questionnaire, and a questionnaire on demographic factors, including past medical history, smoking, alcohol consumption, and life style was also administered."
"The prevalences of H. pylori IgG in cases and controls were 80.7% and 71.2%, respectively, and the odds ratio (OR) of H. pylori for gastric cancer was 1.68 (95% confidence interval (CI): 1.14, 2.44), after adjusting for age, sex, educational level, and a past medical history of gastritis or gastric ulcer," said the scientific assembly.
The researchers concluded, "In a stratified analysis, vitamin C intake was found to modify the relation between H. pylori and gastric cancer."
Kim and colleagues published their study in European Journal of Epidemiology (Effect modification by vitamin C on the relation between gastric cancer and Helicobacter pylori. Eur J Epidemiol, 2005;20(1):67-71).
