ABSTRACT
Context Fructose is a monosaccharide frequently present in natural and artificial juice fruits. When the concentration of fructose in certain food is present in excess of glucose concentration some individuals may develop fructose malabsorption. Objectives To report the frequency of fructose malabsorption utilizing the hydrogen breath test in children with gastrointestinal and/or nutritional disorders. Methods Between July 2011 and July 2012, 43 patients with gastrointestinal and/or nutritional disorders, from both sexes, were consecutively studied, utilizing the hydrogen breath test with loads of the following carbohydrates lactose, glucose, fructose and lactulose. Fructose was offered in a 10% aqueous solution in the dose of 1 g/kg body weight. Samples were collected fasting and at every 15 minutes after the intake of the aqueous solution for a 2 hour period. Malabsorption was considered when there was an increase of >20 ppm of hydrogen over the fasting level, and intolerance was diagnosed if gastrointestinal symptoms would appear. Results The age of the patients varied from 3 months to 16 years, 24 were boys. The following diagnosis were established irritable bowel syndrome with diarrhea in 16, functional abdominal pain in 8, short stature in 10, lactose intolerance in 3, celiac disease in 1, food allergy in 1 and giardiasis in 1 patient. Fructose malabsorption was characterized in 13 (30.2%) patients, and intolerance in 1 (2.3%) patient. The most frequent fructose malabsorption was characterized in 7 (16.3%) patients with irritable bowel syndrome and in 4 (9.3%) patients with functional abdominal pain. Conclusions Patients with irritable bowel syndrome and functional abdominal pain were the main cause of fructose malabsorption. .
RESUMO
Contexto Frutose é um monossacarídeo frequentemente presente em sucos de frutas naturais e artificiais. Quando a concentração de frutose em determinados alimentos está presente em excesso de glicose, alguns indivíduos podem apresentar má absorção à frutose. Objetivo Descrever a freqüência de má absorção à frutose utilizando o teste do hidrogênio no ar expirado em crianças com transtornos digestivos e/ou nutricionais. Métodos Durante o período compreendido entre julho de 2011 e julho de 2012 foram investigados de forma consecutiva 43 pacientes, de ambos os sexos, com suspeita de má absorção, por meio do teste hidrogênio no ar expirado com sobrecarga dos seguintes carboidratos lactose, glicose, frutose e lactulose. A frutose foi administrada em solução aquosa 10% à dose de 1 g/kg de peso. Foram obtidas amostras em jejum e, após a ingestão da solução, a cada 15 minutos durante 2 horas. Foi considerada má absorção quando houve incremento >20 ppm de hidrogênio no ar expirado em relação ao jejum, e intolerância caso surgissem sintomas após a sobrecarga. Resultados A idade dos pacientes variou de 3 meses a 16 anos, 24 meninos. Foram estabelecidos os seguintes diagnósticos síndrome do intestino irritável com diarréia 16, dor abdominal funcional 8, baixa estatura 10, intolerância à lactose 3, doença celíaca 1, alergia alimentar 1 e giardíase 1. Má-absorção à frutose foi caracterizada em 13 (30,2%) pacientes; observou-se intolerância em 1 (2,3%) deles. Síndrome do intestino irritável com diarréia em 7 (16,3%) e dor abdominal funcional em 4 (9,3%) pacientes foram os transtornos com maior prevalência ...
