Abstract: Non-ulcerous dyspepsia is common among sub-Saharan people migrating into Spain. Given the high prevalence of H. pylori (HP) infection in their countries of origin, we studied the prevalence of infection in this population, and specifically the prevalence of infection by the more virulent, cagA-positive strains (CAP). 140 sub-Saharan immigrants recently arrived to Gran Canaria (Canary Islands, Spain) were studied. 80.7% were male, with a mean age of 24.2 y. 90.7% tested seropositive for HP and 72.2% of them carried antibodies against the 'pathogenicity island' cagA. We did not find any relationship between the presence of these antibodies and the clinical variables studied. We can conclude that HP infection is virtually universal in this population, with a high percentage of infection by CAP strains.
