Helicobacter pylori: the African enigma.

Data on Helicobacter pylori infection in Africa are at odds in several aspects with those published in the west. Gastric H pyloni infection is common, almost ubiquitous in Africa, but the pattern of infection, age of acquisition, environmental, dietary, and genetic influences are different from those in the west. These differences alter the pathological role and clinical relevance of the organism in Africa where, apart from gastritis, there is no established correlation between H pyloni infection and upper gastrointestinal disease.
