Multiple food hypersensitivity as a cause of refractory chronic constipation in adults

2006

Chronic constipation that is unresponsive to laxative treatment is a severe illness, but children unresponsive to laxatives have been successfully treated with an elimination diet. We report the first cases of refractory chronic constipation caused by food hypersensitivity in adults. Four patients with refractory constipation who were unresponsive to high doses of laxatives were put on an oligo-antigenic diet and underwent successive double-blind, placebo-controlled, food challenges (DBPFC). Routine laboratory tests, immunological assays, colonoscopy, esophago-gastroduodenoscopy and rectal and duodenal histology were performed. While on an elimination diet, bowel habits normalized in all pa…

Chronic constipation and food intolerance: A model of proctitis causing constipation

2005

OBJECTIVE: Chronic constipation in children can be linked to cow''s milk intolerance (CMI) but the existence of a food intolerance-dependent proctitis is still debated. The aim of this study was to evaluate the histologic data in patients with food intolerance-related constipation. MATERIAL AND METHODS: Fifty-two consecutive patients (22 M, median age 4 years) with chronic constipation unresponsive to common treatment were enrolled. All patients were put on a cow''s milk-free diet for 4 weeks and those uncured on this diet underwent a subsequent 4-week period of oligoantigenic diet. In the patients cured on elimination diet, a subsequent double-blind food challenge was performed to confirm …

Food intolerance and chronic constipation: manometry and histology study

2006

BACKGROUND: Chronic constipation in children can be caused by cows' milk intolerance (CMI), but its pathogenesis is unknown. AIMS: To evaluate the histology and manometry pattern in patients with food intolerance-related constipation. PATIENTS AND METHODS: Thirty-six consecutive children with chronic constipation were enrolled. All underwent an elimination diet and successive double-blind food challenge. All underwent rectal biopsy and anorectal manometry. RESULTS: A total of 14 patients were found to be suffering from CMI and three from multiple food intolerance. They had a normal stool frequency on elimination diet, whereas constipation recurred on food challenge. The patients with food i…

Harmful effect of immunotherapy in children with combined snail and mite allergy

2002

Abstract Background: With respect to allergy, the possibility of cross-reactivity between snail and mite is well recognized, and anecdotal reports suggesting that allergen immunotherapy with mite extract can worsen snail-induced allergy exist. Objective: We describe the effect of immunotherapy in 4 children with snail-mite allergy. Methods: Four children (1 boy and 3 girls; 9-13 years of age) had consistent clinical histories (mild immediate respiratory symptoms after ingestion) and positive skin reactions for allergy to snail. They also had mite-induced asthma and were therefore prescribed subcutaneous specific immunotherapy and subsequently followed. Results: Several months (8-25) after s…

Tropomyosin: A panallergen that causes a worldwide allergic problem

2021

Background: Panallergens are proteins that take part in key processes of organisms and, therefore, are ubiquitously distributed with highly conserved sequences and structures. One class of these panallergens is composed of the tropomyosins. The highly heat-stable tropomyosins comprise the major allergens in crustaceans and mollusks, which make them important food allergens in exposed populations. Tropomyosins are responsible for a widespread immunoglobulin E cross-reactivity among allergens from different sources. Allergic tropomyosins are expressed in many species, including parasites and insects. Methods: This panallergen class is divided, according to it capacity of induced allergic symp…

Prevalence of Wine Intolerance

2012

Background Wine is an ancient food product, ubiquitous across cultures all over the world. Its effects on health have been extensively studied, yet there have been only a few case reports of wine intolerance or wine allergy. We studied the prevalence of self-reported wine intolerance in the adult population of Mainz, Germany.

Oral Allergy Syndrome (OAS). General and stomatological aspects

2008

Oral Allergy Syndrome (OAS) is a special contact allergy conditioned by specific amino acids in food allergens, usually fruits, as well as some proteins from different pollens. It is usually manifested in the mouth, however relatively little is known about the syndrome in Odontology. OAS is a fairly common adverse reaction that occurs after ingesting certain foods, such as peaches or apples, produced in atopic individuals who usually suffer from rhinitis, bronchial asthma or both. This syndrome mainly affects the oral cavity and oropharynx, provoking minor local alterations, although there may be serious systematic reactions, making it important to distinguish it from other oral processes w…
