“…Outro fator importante é o uso indiscriminado de antiparasitários, já que tem sido relatado que pacientes previamente tratados com anti-helmínticos, em dose única, apresentaram redução nas infecções por A. lumbricoides e T. trichiura, porém elevação da infecção por G. lamblia 24 . A prevalência verificada no presente estudo foi semelhante àquelas encontradas em outros trabalhos realizados com diferentes amostras da população brasileira de baixa condição socioeconômica [25][26][27] . Apesar de a área de estudo ser endêmica para geo-helmintíases, neste estudo não houve interferência de coinfecções ativas por helmintos.…”

Objectives: There is a high incidence of intestinal parasite infection in urban areas in the Northeast of Brazil. Giardia lamblia infections have been associated with increased prevalence of cutaneous allergies and gastrointestinal disorders. However, little is known about the relationship between giardiasis and allergic diseases of the airways. The present study aimed to investigate the possible association between respiratory allergic diseases and infections by G. lamblia in children from urban areas. Methods:This study recruited 110 patients of both sexes aged 5-15 years. Patients were administered a questionnaire evaluating clinical symptoms and were given skin tests, parasite tests and serum tests. Results:A high incidence of G. lamblia was observed (45%, 50/110). Infections by this protozoan were not associated with increased risk of respiratory allergy (p = 0.075), high total IgE levels (p = 0.701), positive specific IgE tests (p = 0.250), or positive skin tests for a range of environmental allergens (p = 0.239). Conclusion:This study demonstrated that symptoms of asthma, skin allergy and serum markers were not associated with G. lamblia infections in this sample of children from urban areas.J Pediatr (Rio J). 2012;88(3):233-8: Giardia lamblia, rhinitis, asthma, skin prick test. ResumoObjetivo: Uma elevada incidência de enteroparasitoses é encontrada em regiões urbanas do nordeste brasileiro. As infecções por Giardia lamblia têm sido relacionadas com aumento da prevalência de alergias cutâneas e gastrointestinais. Contudo, ainda existe pouca informação sobre a associação entre a giardíase e doenças alérgicas das vias aéreas. Diante disso, o presente estudo se propôs a verificar a relação entre a infecção por G.lamblia em crianças de área urbana e reatividade alérgica respiratória.Métodos: O estudo incluiu 110 pacientes, de ambos os sexos e idades, entre 5 e 15 anos. Os pacientes foram submetidos a questionários de avaliação dos sintomas clínicos, testes cutâneos de leitura imediata e exames coproparasitológicos e sorológicos.Resultados: Foi verificada uma frequência elevada de crianças infectadas por G. lamblia (45%, 50/110). A infecção pelo protozoário não foi associada com maior risco de alergias respiratórias (p = 0,075), elevação de IgE total (p = 0,701), IgE específica (p = 0,250) ou teste cutâneo positivo para diferentes alérgenos ambientais (p = 0,239). Conclusão:O estudo demonstrou que a presença dos sintomas de asma, atopia cutânea e marcadores sorológicos não foram associados com a presença de infecção pela G. lamblia nessa amostra de crianças.J Pediatr (Rio J). 2012;88(3):233-8: Giardia lamblia, rinite, asma, teste cutâneo.

“…A elevada prevalência de infestação parasitária e hepatite A, encontrada nas comunidades do PIX, é uma evidência indireta da via fecal-oral da infecção por H. pylori 27,28 . Além disso, diversos autores sugerem que ocorra a transmissão por H. pylori através da via fecal-oral 29,30 .…”

Objective: To evaluate the prevalence of Helicobacter pylori infection and its association with intestinal parasitoses in children from indigenous communities of the Xingu Indian Reservation, in Brazil.Methods: A total of 245 Native Brazilian children between 2 and 9 years of age, from six villages of the Xingu River region, a tributary of the Amazon River, were assessed. H. pylori was detected using the 13 C-urea breath test. Breath samples were collected at baseline and 30 minutes after ingestion of 50 mg of 13 C-urea diluted with 100 mL of water flavored with passion fruit juice and sweetener. Stool samples were collected for the stool ova and parasites exam for 202/245 (82.4%) children. Results:The overall prevalence of H. pylori was 73.5%. A significant association of H. pylori with increased age was observed among the different villages and ethnic groups. Positive results for the presence of parasites -97.5% (198/202) -from the stool samples collected showed no association with H. pylori. Giardia showed an association with H. pylori in the multivariate analysis. Risk factors for H. pylori infection were observed in Kisêjê and Kaibi ethnic groups (OR [odds ratio] = 3.36 and 4.00, respectively), as well as in Tuiararé, Ngojwere, Capivara, Diauarum, and Pavuru villages (OR = 8.10, 4.10, 4.88, 1.85, and 1.40, respectively). Conclusions:H. pylori infection is highly prevalent in these communities, as well as intestinal parasitoses. However, there were significant differences in the prevalence of H. pylori among the diverse villages studied. Giardia was closely associated with H. pylori infection.

ResumoObjetivo: Avaliar a prevalência da infecção por Helicobacter pylori e sua associação com parasitoses intestinais em crianças da comunidade indígena do Parque Indígena do Xingu. Métodos:Foram incluídas 245 crianças indígenas entre 2 e 9 anos, de seis aldeias da região do rio Xingu, afluente do Amazonas. H. pylori foi detectado pelo teste respiratório com ureia-13 C. Foram coletadas amostras de ar expirado, em jejum e 30 minutos após a ingestão de 50 mg de ureia-13 C diluída em 100 mL de água aromatizada com suco de maracujá. Foram coletadas amostras de fezes de 202/245 (82,4%) crianças para exame protoparasitológico. Conclusões: Foi encontrada alta prevalência de H. pylori e de parasitose intestinal em crianças nas comunidades presentemente investigadas. No entanto, houve diferença significativa na prevalência do H. pylori entre as diversas aldeias estudadas. Verificou-se associação entre a presença de giárdia e a infecção por H. pylori.

“…The rate of infestation in the present study is similar to the reported in other studies in indigenous communities in Brazil, for instance in Suruí Indians (29.5%) and in the ethnic group Karitiana (10.8%) from State of Rondônia, in Maxakali Indians, from State of Minas Gerais (18.16%), in members of the ethnic group Kaigàng from State of Pará (31.7%) and in children from the Xingu Indian Reservation (28.5%) [10,11,12,13,14]. Our results are also in agreement with studies performed in other parts of the world [15,16].…”

A total of 1528 stool samples were examined during a survey of intestinal parasites in 542 members of the Tapirapé ethnic group (279 females and 263 males), who live in the Brazilian Amazon region of Mato Grosso. Overall, 542 individuals from six indigenous villages were enrolled of whom 45 (8.3%) were positive for Hymenolepis nana based on analysis by microscopy of fecal concentrates. H. nana was more prevalent in male individuals (77.8%) as compared to females (22.2%). Moreover, males aged under 15 years have been associated with positivity for H. nana (P = 0.02). This study is the first report of the prevalence of H. nana in members of the indigenous Tapirapé ethnic group from the Brazilian Amazon.
