Effects of asymptomatic Giardia intestinalis infection on carbohydrate absorption in well-nourished Mexican children.

Abstract: Abstract. The aim of this study was to evaluate carbohydrate absorption in well-nourished children with asymptomatic giardiasis. Two groups were selected based on results of stool examination of 211 children attending pre-school centers in Hermosillo, Sonora, Mexico: a control group of six non-infected children, and an infected group of seven children harboring Giardia intestinalis, without gastrointestinal symptoms of disease. Carbohydrate absorption was determined in the control group, before and after drug … Show more

“…A significant relationship between the variables was confirmed, indicating a high probability that individuals with intestinal parasites will suffer some kind of malabsorption, or, analyzed in reverse, patients with malabsorption might present intestinal parasitism (around 40%). This situation had already been cited in previous studies such as that carried out by Moya-Camarena et al (2002) [5], concluding that an effect on mucosal absorption may be one of the intestinal side effects generated by intestinal parasites. Of the total cases of malabsorption, a predominance of the inability to absorb fructose was observed (63.6%), and this condition was studied in relation to the presence or absence of intestinal parasites.…”

“…Increasingly, scientific studies are emerging on the possible etiological role of intestinal parasites in functional digestive disorders, characterized by abdominal discomfort associated with an altered intestinal reactivity in response to luminal (infectious agents or food) or psychological stimuli. Several authors have agreed on the positive correlation between pathologies (such as dyspepsia, carbohydrate intolerance/malabsorption, food intolerance, and irritable bowel syndrome (IBS)) and intestinal protozoal diseases highlighting Giardia intestinalis [5][6][7][8].…”

“…This effect may result from the malabsorption of nutrients that occurs during parasite infections and during diarrhea episodes associated with infections. Giardiasis, for example, has been associated with a decrease in energy and zinc absorption (Valencia et al, 1995;Moya-Camarena et al, 2002). Giardiasis is associated with steatorrea as well, which may reduce the absorption of vitamin A (Solomons 1982).…”

“…En relación al efecto de las parasitosis sobre el estado nutricional de las personas, se ha informado un aumento en la demanda de nutrientes por el parásito en sí o por sus acciones específicas (Jardim- Bothelo et al, 2008), tales como el bloqueo de la superficie de absorción intestinal por parte de Ascaris lumbricoides (Stephenson et al, 2000, Crompton y Nesheim, 2002, por pérdida de sangre en el caso de los ancylostomideos (Stoltzfus et al, 1997) o por reducción de la absorción de hidratos de carbono por Giardia lamblia (Moya-Camarena et al, 2002). Así, cuando las infecciones parasitarias son crónicas se observa una considerable pérdida de peso corporal, retraso pondo-estatural y disminución del rendimiento intelectual (Stephenson et al, 2000;Jardim-Bothelo et al, 2008).…”
