The Gluten File
Many people with Celiac Disease or Non-Celiac Gluten Sensitivity find they have problems with additional food intolerances. In Celiac Disease, this might be temporary and once the intestinal villi have healed, sometimes the secondary problem foods can be successfully added back. In those with multiple food sensitivies, one has to question overall gut health and other factors that may be involved.
The difference between IgE (classic food allergy) and IgG (delayed) food allergy is still somewhat controversial, but…it seems IgG food allergy is gaining recognition as a real player in ill health.
I’m not pretending to have all the answers when it comes to food allergy, but I do know it can be a subject of great interest as we struggle to be well. Hope some of the information I leave here can speed your journey to better health!
Effect of probiotics on intestinal barrier function.

B. lactis inhibited the gliadin-induced increase dose-dependently in epithelial permeability, higher concentrations completely abolishing the gliadin-induced decrease in transepithelial resistance. The same bacterial strain also inhibited the formation of membrane ruffles in Caco-2 cells induced by gliadin administration. Furthermore, it also protected the tight junctions of Caco-2 cells against the effects of gliadin, as evinced by the pattern of ZO-1 expression. We conclude thus that live B. lactis bacteria can counteract directly the harmful effects exerted by coeliac-toxic gliadin and would clearly warrant further studies of its potential as a novel dietary supplement in the treatment of coeliac disease.

Milk protein IgG and IgA: the association with milk-induced gastrointestinal symptoms in adults.
PMID: 19842221 Oct 2009
We demonstrated a high IgG response in a very large subject group to milk and milk derivatives, and egg albumin antigens, and we conclude that the validated ELISA test may be applied for the serum/plasma IgG antibody level determination as a useful indicator of adverse reactions to food and food hypersensitivity.

Purpose: To establish the interdependence between the intensity of the clinical symptoms and the acid reflux index in children with primary GER and GER secondary to cow’s milk protein allergy (CMA) and/or other food allergies (FA).

CONCLUSION: Serum IgG4 assay may play a role in rul-ing out food intolerance, because of its satisfactory negative predictive value (0.99).

There are studies supporting IgG testing, as well as many anecdotal success stories based upon IgG testing. Controversial, maybe. End of story, I think not. jcc
CONCLUSION: According to the results obtained, serum IgG antibodies to common food should be investigated in patients with migraine.

CONCLUSIONS: Abnormal immune reactions mediated by IgG antibodies coexisted in patients with IBS. It is of great significance in treating IBS by eliminating the allergic foods according to the serum level of food-specific IgG antibodies.

A mucosal inflammatory response similar to that elicited by gluten was produced by CM protein in about 50% of the patients with coeliac disease. Casein, in particular, seems to be involved in this reaction.

Review article: chronic constipation and food hypersensitivity – an intriguing relationship.
PMID: 17059511 Nov 2006
The mechanism by which food activates mucosal immune system is uncertain, but food specific IgE and IgG4 appeared to mediate the hypersensitivity reaction in a subgroup of IBS patients. Exclusion diets based on skin prick test, RAST for IgE or IgG4, hypoallergic diet and clinical trials with oral disodium cromoglycate have been conducted, and some success has been reported in a subset of IBS patients.
In some cases, nausea and vomiting are directly triggered by food, e.g. in patients suffering from food allergy or food intolerances. In other cases, food is not the primary cause but dietetic manipulations may still contribute to the management of the nausea and vomiting. Therefore, food plays an important pathophysiological and therapeutic role in nausea and vomiting. In the present article, we describe the most relevant nutrient triggers for nausea and vomiting, discuss food allergy and intolerance as cause of nausea and vomiting, propose a clinical classification of nausea and vomiting, and present in detail dietetic and other therapeutic strategies of relevance for the management of nausea and vomiting.

RESULTS: Significant improvement has been noted in infants receiving Lactobacillus GG in their extensively hydrolyzed formula. CONCLUSIONS: It is likely more studies will be forthcoming with different probiotic organisms in the prevention and treatment of allergic disorders in children and adults.

Food allergies are increasing in incidence, and the variety of triggering antigens is widening. There is also an increased recognition of the breadth of immunologically mediated responses to dietary antigens; the area of non-IgE-mediated food allergy is belatedly acquiring scientific respectability, aided by improved clinical recognition and basic scientific studies.

It seems that the physician’s opinion is influenced by “general knowledge” more than by his own experience. We suggest emphasizing through education that there are two distinct entities of cow’s milk intolerance: IgE-mediated allergy and non-IgE-mediated.

Non-IgE-mediated or T-cell-mediated allergic GI disorders include dietary protein enteropathy, protein-induced enterocolitis, and proctitis. All these conditions share a common denominator: the response of the immune system to a specific protein leading to pathologic inflammatory changes in the GI tract. This immunological response can elicit symptoms such as diarrhea, vomiting, dysphagia, constipation, or GI blood loss, symptoms consistent with a GI disorder.

The overall results demonstrated a 71% success rate for all symptoms achieving at least a 75% improvement level. Of particular interest was the group of patients with chronic, disabling symptoms, unresponsive to other intensive treatments. Whereas 70% obtained 75% or more improvement, 20% of these patients obtained 100% relief.

Gastrointestinal immunopathology and food allergy.
Although immunoglobulin (Ig)E-mediated allergies are readily identifiable, non-IgE-mediated allergies present more diagnostic difficulty. Gastroesophageal reflux, esophagitis, subtle enteropathy, and constipation were frequent in both groups.

Abnormalities of Th1 function in non-IgE food allergy, celiac disease, and ileal lymphonodular hyperplasia: a new relationship?
Although previously thought to be triggered primarily by an IgE-mediated mechanism of injury, considerable evidence now suggests that non-IgE mechanisms may also be involved in the pathogenesis of FA.

Gastrointestinal food allergies: do they exist?
Clinical symptoms are unspecific and include nausea, vomiting, abdominal pain, cramping and diarrhea. Intestinal mast cells, as well as intestinal eosinophils, have been shown to be involved in the pathogenesis of food-allergy-related enteropathy. Elimination diet still presents the main basis of therapy.
