RESUMO
BACKGROUND: Intestinal amebiasis is an important public health problem worldwide. More severe disease is associated with young age, malnutrition and immunosuppression. AIM: The aim of this study is to evaluate the prevalence and characteristic nature of intestinal amebiasis among pediatric population, and compare it with other causes of gastroenteritis. MATERIALS AND METHODS: This is a retrospective comparative study conducted at Makassed General Hospital between January 2008 and December 2012, including all pediatric patients between birth and 15 years of age, who presented with symptoms of acute gastroenteritis. RESULTS: One thousand three hundred ninety-five patients were included in the study, and were divided into four groups: Group I (Entameba histolytica group = 311 cases, 22.3%), group II (Rotavirus group = 427 cases, 30.6%), group III (bacterial group = 107 cases, 7.7%), group IV (unidentified group = 550 cases, 39.4%). Significant leukocytosis, neutrophilia and positive C-reactive protein were found among more than 50% of admitted Entemaba histolytica cases with a picture of severe invasive disease in young infants. CONCLUSION: Entameba histolytica can be an emerging serious infection, especially when it finds suitable environmental conditions and host factors, so we should be ready to face it with effective preventive measures.
RESUMO
STATEMENT OF THE PROBLEM: Helicobacter pylori plays a major etiologic factor in the pathogenesis of chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and mucosa associated lymphoid tissue lymphoma. However, most of the infected subjects remain asymptomatic. The aim of this study is to establish fecoprevalence of Helicobacter pylori infection in a convenient non-probabilistic sample of asymptomatic Lebanese children. METHODS: Four-hundred fourteen children aged between one month and 17 years of different socioeconomic standards were selected for Helicobacter pylori antigen testing in stool. Demographic characteristics, health and nutritional status were obtained through a questionnaire. RESULTS: Fecoprevalence of Helicobacter pylori infection was 0.21 of whom 28.7% were between 0-3 years, 34.5% between 4-9 years and 36.8% between 10-17 years. Seventy-five (86.2%) of the fecopositive children were from low socioeconomic standards and 12 (13.8%) were from middle to high socioeconomic standards (p < 0.0001). Environmental variables demonstrated higher frequency of fecopositivity in children living in overcrowded houses, lower family income and poor parental education (p < 0.05). CONCLUSIONS: Helicobacter pylori is prevalent in asymptomatic Lebanese children. Prevention is worthy by improving the levels of education and the standards of hygiene.
