[CONTRIBUTION STUDY TO THE EPIDEMIOLOGY OF HELICOBACTERPYLORI IN PERU: ANALYSIS OF 3005 CASES]
Compiling our observations from the last 15 years in regard to the epidemiology of Helicobacter pylori in Perú, we have analized 3005 cases. Studying and comparing the rates of infection among japanese inmigrants living in Perú for more than 10 years, niseis, japanese visitors and peruvians, we found similar rates. According to these results it seems that at least in japaneses there is not any genetic predisposition to acquire the infection. Studying peruvians of different socioeconomic levels, we observed similar rates of infection with the exception of women of high socioeconomic level. It seems that the last group of people is not exposed to the different mechanisms of infection. We found similar rates of infection in patients of low socioeconomic level living in the coast, sierra and jungle. Our studies in children showed that the infection is acquired during early childhood. Therefore in Perú we have not observed an ascending rate of infection according to age as has been described in industrialized countries. Analizing water from 48 sources we found Helicobacter pylori in 24 samples, 20 of them were taken from the municipal source of water. Water seems to be an important vehicle of infection, according to our studies, in children drinking water from different sources.
