“…At least some studies have suggested that younger children, because they have shorter intestinal transit times, are more likely to shed H. pylori in their feces and thus spread infection than are older persons [40]. The exact role that older infected persons might play in the infection of the young children in our cohort was not explored in this study.…”

Seroincidence ofHelicobacter pyloriInfection in a Cohort of Rural Bolivian Children: Acquisition and Analysis of Possible Risk Factors

High seroprevalence rates for Helicobacter pylori are reported in developing countries, yet few seroincidence studies exist that determine age of initial acquisition and risk factors for H. pylori seroconversion. Two H. pylori serosurveys were conducted in August 1996 and November 1997. Of 188 children aged 21 months to 6 years who were seronegative in the first survey, 44 (23%) had seroconverted at follow-up, yielding an 18% annual seroincidence. The largest increase in seroincidence occurred between children aged 2 years (10%) and children aged 3 years (32%). Use of a lidded, narrow-mouthed water vessel was protective against seroconversion (odds ratio [OR], 0.3; 95% confidence interval [CI], 0.1-0.8), and the presence of another H. pylori-seropositive sibling in the household was a risk factor for seroconversion (OR, 3.1; 95% CI, 1.3-8.7). Although not a randomized intervention trial, this study suggests that the use of a narrow-mouthed water vessel may prevent the transmission of H. pylori in households in developing countries.

ÖZET Amaç: Gelişmekte olan ülkelerde H. pylori enfeksiyonu gelişmiş ülkelere göre daha sık ve daha erken yaşta görülmektedir. Etyopatogenezinde kalabalık ailelerde yaşam, annenin eğitim seviyesinin düşük olması, düşük ekonomik gelir, kirli içme suları gibi faktörlerin varlığında daha sık görüldüğü bildirilmiştir. Sosyoekonomik durumu iyi olmayan bölgelerde intestinal parazitozların da daha sık görüldüğü bilinmektedir. Bu çalışmada amaç, H. pylori gastriti olduğu endoskopik ve histopatolojik olarak ispatlanmış hastalarda intestinal parazit sıklığınının incelenmesidir. ABSTRACT Objective: H. pylori infection is more frequent and is seen in younger ages in developing countries when compared to developed countries. Etiopathogenetic factors include living in crowded families, low educational level of mother, low income and infected drinking water.Intestinal parasites are more frequent in low socioeconomical populations. In this study, it was aimed to determine the prevalence of intestinal parasite in patients with H. pylori gastritis proven with endoscopic and histopathological study. Methods: Parasitology laboratory results of children who had undergone upper gastrointestinal system endoscopy (UGE) and were proved to have H. pylori gastritis were evaluated retrospectively. Stool samples were examined using native lugol and precipitation by formol ethyl acetate methods.

Descritores ResumoRealizou-se revisão da epidemiologia da infecção pelo Helicobacter pylori, com o objetivo de analisar sua importância na infância e adolescência no que se refere à incidência, à prevalência, às vias de transmissão e aos fatores de risco. Para tanto, realizou-se uma pesquisa nas bases de dados Lilacs (OPS/Bireme) e Medline (National Library of Medicine) e no banco de teses da Universidade de São Paulo dos anos de 1983 a 1999. A análise da literatura levou à conclusão de que a infecção pelo Helicobacter pylori é adquirida principalmente durante a infância, apresenta aumento da prevalência com a idade, os principais fatores de riscos estão relacionados ao baixo nível socioeconômico e o mecanismo de transmissão permanece desconhecido. AbstractThe scope of the review is to study the epidemiological aspects of Helicobacter pylori infection and its importance during childhood and adolescence, focusing on incidence, prevalence, transmission and risk factors. The study's references included the following databases: LILACS (PAHO/ Bireme), MEDLINE, the US's National Library of Medicine and the thesis developed at University of São Paulo for the period 1983 to 1999. It was noted that Helicobacter pylori infection is mainly acquired during childhood, age-related prevalence, main risk factors are associated to low socioeconomic status, and its transmission mechanism remains unclear.
