Helicobacter pylori infection is the most common chronic bacterial infection in humans. It is recognized as the major etiologic factor in the development of chronic gastritis and peptic ulcer disease . H. pylori has also been related to extragastrointestinal diseases , including iron deficiency anemia and other micronutrient deficiencies . However, it is unclear as to why only a small number of infected patients develop iron deficiency, despite the worldwide distribution of H. pylori infection. In Argen tina previous epidemiologic studies showed an in – fection prevalence of 40% in symptomatic children and a 15% prevalence in the asymptomatic pop u lation. Whether H. pylori infection is related to micro – nutrient malnutrition remains controversial. For that reason, the aim of our study was to determine the relationship between H. pylori in – fec tion and iron, copper and zinc nutritional status in symptomatic chil dren from Buenos Aires, Argen tina.
