nutritional factors and helicobacter pylori infection in colombian children.helicobacter pylori infection occurs most frequently in impoverished populations; however, little is known about specific determinants of susceptibility. this report describes the relationship between h. pylori infection and nutritional indicators among children from a rural village in the colombian andes, where a prevalence of 69% was observed in children from 2 to 9 years old.19979360204
effect of helicobacter pylori infection on growth velocity of school-age andean children.helicobacter pylori infection affects about half of the world's population and is usually acquired in childhood. the infection has been associated with chronic gastritis, peptic ulcer, and stomach cancer in adulthood. little is known, however, about its consequences on child health. we examined the effect of h. pylori infection on growth among school-age children in the colombian andes by comparing growth velocity in the presence and absence of h. pylori infection.201121068668
plasma selenium measurements in subjects from areas with contrasting gastric cancer risks in colombia.an inverse association between selenium status and incidence of different neoplasias including gastric cancer has been reported. this pilot study aimed to determine and compare selenium status in two colombian populations with different gastric cancer risks: a high-risk area in the volcanic region of the andes mountains and a low-risk area on the pacific coast.200818375257
[prevalence of helicobacter pylori infection in physicians in medellín, colombia].infection by helicobacter pylori (h. pylori) and its associated complications, such as gastric cancer, constitute a true public health problem due to the high morbidity and mortality rates in colombia and latin america, where it is highly prevalent.200717684940
intestinal helminthiasis in colombian children promotes a th2 response to helicobacter pylori: possible implications for gastric carcinogenesis.colombians living in coastal tumaco have a lower incidence of helicobacter pylori-associated gastric cancer compared with residents of pasto in the high andes. considering the risk for h. pylori disease seems affected by features of bacterial virulence and host polymorphisms, other poorly understood influences, such as concurrent helminthiasis, may also be important.200515941957
helicobacter pylori infection in the colombian andes: a population-based study of transmission pathways.in 1992, the authors studied helicobacter pylori infection and exposures relevant to person-to-person, waterborne, foodborne, and zoonotic transmission in a census sample of 684 2-9-year-old children in aldana, nariño, a rural community in the colombian andes. h. pylori prevalence, as determined by the 13c-urea breath test, was 69%, and prevalence increased from 53% in 2 year-olds to 87% in 9 year-olds. beginning at 3 years of age, a higher percentage of males compared with females were infected ...19968686698
