INTRODUCTION: Lactose intolerance is a common disease in pediatrics, and its wrong diagnosis will lead to morbidity. The primary objective of this study was to assess the usefulness of an increased waist circumference during the hydrogen breath test as a predictor of lactose intolerance. The secondary objective was to analyze the impact of body mass index, waist circumference measurement, and age on the abdominal distension of patients with lactose intolerance. POPULATION AND METHODS: A total of 138 subjects aged 3 to 15 years were included...

INTRODUCTION: Inflammatory bowel disease is a chronic condition of the gastrointestinal tract, comprising mainly Crohn disease (CD) and ulcerative colitis (UC). Both of them are frequently encountered in children, being multifactorial conditions, with an unclear etiology. PATIENTS CONCERNS: We present 4 cases of inflammatory bowel disease (IBD) in children in order to underline the variable evolution depending on the patient's particularities. DIAGNOSIS, INTERVENTIONS AND OUTCOMES: The first case, a 13-year-old male patient, with a history of Henoch-Schonlein purpura, was admitted for rectal bleeding and weight loss, with normal laboratory parameters...

β-galactosidase was successfully encapsulated within an amino-functionalised silica matrix using a "fish-in-net" approach and molecular imprinting technique followed by covalent binding of lysozyme via a glutaraldehyde-based method. Transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy were used to characterise the silica matrix hosting the two enzymes. Both encapsulated β-galactosidase and bound lysozyme exhibited high enzymatic activities and outstanding operational stability in model reactions...

Type 2 diabetes mellitus consists of dysfunctions characterized by hyperglycemia and resulting from combination of resistance to insulin action and inadequate insulin secretion. Most of diabetic patients report significant gastrointestinal symptoms. Entire GI tract can be affected by diabetes from oral cavity to large bowel and anorectal region. Proteins, carbohydrates, fats, and most fluids are absorbed in small intestine. Malabsorption may occurs when proper absorption of nutrients does not take place due to bacterial overgrowth or altered gut motility...

Lactose, the principle sugar in milk, is a disaccharide hydrolyzed by intestinal lactase into glucose and galactose, which are absorbed directly by diffusion in the intestine. The decline of lactase expression (or hypolactasia) in intestinal microvilli after weaning is a normal phenomenon in mammals known as lactase deficiency. It is observed in nearly 75% of the world population and is an inherited autosomal recessive trait with incomplete penetrance. It is caused by SNPs in a regulatory element for lactase gene...

Phytosterols found naturally in plants are known to reduce cholesterol absorption in the gut. The traditional southern Chinese diet typically contains many vegetables and not much meat, and there is high prevalence of lactose intolerance in Chinese; we therefore aimed to test if phytosterols-enriched milk is effective in lowering serum LDL-cholesterol in Chinese. Two hundred and twenty-one participants (41 men and 180 women; age 24-79) without cholesterol-lowering drugs or diabetes mellitus were randomized to daily intake of phytosterols-enriched low-fat milk which contained 1...

Directed modulation of the colonic bacteria to metabolize lactose effectively is a potentially useful approach to improve lactose digestion and tolerance. A randomized, double-blind, multisite placebo-controlled trial conducted in human subjects demonstrated that administration of a highly purified (>95%) short-chain galactooligosaccharide (GOS), designated "RP-G28," significantly improved clinical outcomes for lactose digestion and tolerance. In these individuals, stool samples were collected pretreatment (day 0), after GOS treatment (day 36), and 30 d after GOS feeding stopped and consumption of dairy products was encouraged (day 66)...

BACKGROUND: Probiotics constitute the viable and beneficial microbes, which offer a dietary means to sustain the balance of gastro-intestinal (GI) microflora. Owing to their multiple health benefits, these have recently gained wide attention among researchers for exploring their potential in safeguarding the health of humans and animals. Probiotics could also modulate host-immune responses, thereby help in counteracting the immunological dysfunctions. Probiotics can inhibit the systemic invasion of pathogens entering through the GI mucosa/ oral cavity and have been found to possess effective prophylactic and therapeutic utilities against various infectious pathogens as well as non-infectious diseases and disorders...

Lactose intolerance is characterized by low or inexistent levels of lactase, and the main treatment consists of dietary changes, especially replacing dairy milk by soy milk. Soy contains phytoestrogens, substances with known estrogenic activity, besides, glyphosate-based herbicides are extensively used in soy crops, being frequently a residue in soy beans, bringing to a concern regarding the consumption of soy-based products, especially for children in breastfeeding period with lactose intolerance. This study evaluated the pubertal toxicity of a soy milk rich feeding (supplemented or not with glyphosate, doses of 50 and 100 mg/kg) during prepubertal period in male rats...

BACKGROUND: Anaphylactic reactions involving IgE mediated hypersensitivity have been frequently reported for a number of uncommon foods. However, cases of anaphylaxis to over the counter vitamins and oral supplements have been rarely published. Lactose intolerance affects approximately 20% of Canadians and roughly 70% of the world's population of any age. Lactose intolerance develops primarily due to the absence of the enzyme lactase and treatment involves avoidance of lactose-containing foods or ingestion of commercially available lactase enzyme preparations prior to their consumption...

BACKGROUND: Lactase persistence is an autosomal dominant trait commonly distributed in Europe as well as some parts of east Africa and the Arabian Peninsula. Using real-time PCR to detect the -13910C > T variant common in the European population is a reliable analysis although other variants in the probe-binding site may cause errors in analysis. The aim of this study was to determine the prevalence of the variants in a Danish cohort examined for lactose intolerance as well as to improve the real-time PCR analysis for detection of the different variants...

BACKGROUND: Pediatric campers with food allergies are at greater risk for exposure and anaphylaxis. A diagnosis of asthma increases risk for anaphylaxis. Epidemiological investigations of food-allergic children at high risk for allergic reactions requiring intervention in camp settings are lacking. OBJECTIVE: The objectives of this study were to estimate the prevalence of food allergies among otherwise healthy campers in summer camps throughout the United States and Canada, and to assess asthma comorbidity and determine rates of epinephrine autoinjector prescriptions present in this population...

A chromatographic method by HPAEC-PAD was developed and in-house validated for the quantification of low sugar levels in hard cheese, specifically Grana Padano PDO cheese. Particular attention was paid to the extraction procedure, due to residual microbial and enzymatic activities. Specificity in detection and linearity were verified. Recoveries ranged from 93% for lactose to 98% for glucose and galactose. The obtained LOD and LOQ values were, respectively, 0.25 and 0.41mg/100g for lactose, 0.14 and 0.27mg/100g for galactose, and 0...

Although fructose was discovered in 1794, it was realised in recent decades only that its malabsorption can lead to intestinal symptoms while its excessive consumption induces metabolic disturbances. Fructose is a monosaccharide found naturally in most fruits and vegetables. Dietary intake of fructose has gradually increased in the past decades, especially because of the consumption of high fructose corn syrup. With its 16.4 kg/year consumption, Hungary ranks secondly after the United States. Fructose is absorbed in the small intestine by facilitated transport mediated by glucose transporter proteins-2 and -5, and arrives in the liver cells...
