The term "food allergy" refers to adverse immunologic reactions to food. Food allergy is usually mediated by IgE antibody directed to specific food proteins, but other immunologic mechanisms can also play a role. The primary target organs for food allergic reactions are the skin, the gastrointestinal tract and the respiratory ...
Joneja Janice M. - - 1999
The greatest challenge in managing food allergy or intolerance is identifying the food that is responsible for the symptoms. The medical model of a diagnosis based on tests appropriate to the symptoms, which dictates the usual most effective treatment strategy, does not work well in the management of adverse reactions ...

BACKGROUND: The sulfite family of food additives has been implicated in the pathogenesis of wine-induced asthma. However, the evidence supporting this is weak, and because wines have many hundreds of components, nonsulfite-associated mechanisms may also play a role. OBJECTIVES: The aim of the study was to assess the potential sensitivity ...
Sullivan P B - - 1999
Food intolerance is a reproducible adverse reaction to a specific food ingredient that is not psychologically based. Food allergy is a form of food intolerance in which there is evidence that the response is caused by an immunological reaction to food. Other mechanisms of food intolerance include enzyme defects (e.g. ...

BACKGROUND AND OBJECTIVE: Little is known about late phase clinical reactions during oral food challenges and the value of specific IgE in terms of sensitivity and specificity. METHODS: We therefore analysed retrospectively the clinical outcome of 387 oral provocations during double-blind, placebo-controlled food challenge tests in 107 children with atopic ...
Hattevig G - - 1999
This study investigated the long-term effects of maternal dietary avoidance during lactation on the occurrence of atopic symptoms, development of immunoglobulin E (IgE) antibodies to food and inhaled allergens and occurrence of positive skin-prick tests (SPT) in 65 children with a family history of atopy whose mothers adhered to a ...
Williams L W - - 1999
Skin tests by prick technique offer considerable guidance in the diagnosis of food allergy. Negative prick skin tests are powerful evidence against food allergy. Positive food skin tests are slightly to moderately predictive of reaction to a food on DBPCFC. Oral food challenge is necessary for confirmation of food allergy, ...
Feinle C - - 1998
The term "functional dyspepsia" represents a complex of symptoms related to the upper gastrointestinal tract, including epigastric pain, upper abdominal bloating/distension, regurgitation, postprandial fullness, early satiety, nausea and vomiting and frequently reported to occur in connection with food intake. Particularly foods containing fat appear to potently provoke dyspeptic symptoms. Despite ...
Shaw A D - - 1998
Irritable bowel syndrome (IBS) is a frequently occurring, benign functional gastrointestinal disorder with a complex poorly understood pathology which appears to be multifactorial in nature. There is no association with structural or biochemical abnormalities in the gastrointestinal tract. Functional variations in myoelectrical activity, visceral hypersensitivity and illness behaviours have all ...
Eigenmann P A - - 1998
BACKGROUND: Skin prick tests (SPTs) are utilized routinely in the evaluation of food allergy and several authors have discussed their utility. Efforts to standardize SPT reagents and procedures have been made, but the accuracies of different recording techniques have not been clearly defined. The aim of this study was to ...
Caffarelli C - - 1998
Owing to poor reliability of laboratory tests, diagnosis of food allergy is based on clinical response to double-blind placebo-controlled food challenge. The aim of the present study was to assess the value of duodenal IgE-positive cells in the diagnosis of food allergy. Thirty-one children with a history of possible food ...
Moneret-Vautrin D A - - 1998

Vanderhoof J A - - 1998
Adverse reactions to foods involving abnormal immune reactions to food antigens occur in 2-7% of the North American population; the numbers are perhaps higher in children. Both IgE-mediated and non-IgE-mediated allergic responses occur. IgE-mediated allergic responses to foods are the most dramatic and perhaps the most easily diagnosed type of ...
Acero S - - 1998
Carmine (E120), a natural red dye extracted from the dried females of the insect Dactylopius coccus var. Costa (cochineal), has been reported to cause hypersensitivity reactions. We report a case of occupational asthma and food allergy due to carmine in a worker not engaged in dye manufacturing. A 35-year-old nonatopic ...
Henz B M - - 1998
Although chronic urticaria is generally thought to be mostly idiopathic, we have recently provided convincing evidence that in the majority of patients, food ingredients provoke the symptoms and sustain the disease. On a diet largely avoiding preservatives, dyes and natural pseudoallergens, 73% of patients experienced remission of more than 6 ...
Sicherer S H - - 1998
OBJECTIVE: To describe the clinical characteristics of food protein-induced enterocolitis syndrome (FPIES), a symptom complex of severe vomiting and diarrhea occurring several hours after the ingestion of particular food proteins in infants.

Ito K - - 1997
Stimulation of systemic antigen-specific IgE production plays an important role in the mediation of food allergy; however, the mechanism of IgE production against food antigens is not fully understood. The development of relevant animal models may help to elucidate the pathogenesis of food allergy. We here show that DBA/2 mice ...
Sampson H A - - 1997
BACKGROUND: The double-blind, placebo-controlled food challenge (DBPCFC) is the "gold standard" for diagnosis of food hypersensitivity. Skin prick tests and RASTs are sensitive indicators of food-specific IgE antibodies but poor predictors of clinical reactivity. Previous studies suggested that high concentrations of food-specific IgE antibody were predictive of food-induced clinical symptoms. ...
Rancé F - - 1997
The skin prick test is the most widely used test for detecting IgE-mediated food hypersensitivity. Our study aimed to define firstly the correlations between results obtained with prick tests using commercial extracts and fresh foods, and secondly the correlations between these results and those obtained with labial and/or oral challenge. ...
de Boissieu D - - 1997
Six infants suspected of food allergy during breastfeeding were evaluated using prick tests, total IgE, RASTs and intestinal permeability measurements during fast and provocation with mother's milk. An elimination diet was undertaken in mothers, removing first cow's milk protein (CMP), then, when inefficient, all foods suspected on the clinical history ...
Anderson J A - - 1997
True food allergies are much less prevalent than is generally believed. They are more common in infants and children under age three than in older children and adults. Infant colic generally is not caused by a food allergy. In infants, urticaria, eczema or gastrointestinal bleeding may be due to foods ...
Vidal C - - 1997
Hidden allergens in processed foods can provoke severe allergic reactions in sensitive individuals. The presence of soy proteins in typical Spanish sausage products (chorizo, salchichón, mortadella, and boiled ham), doughnut and soup stock cubes has not been reported previously. The present article reports two examples of severe allergic reactions due ...
Bassotti G - - 1997
BACKGROUND: Food hypersensitivity is a frequent complaint by both pediatric and adult subjects. However, notwithstanding patient' belief about 'allergies' related to food stuffs, only a minority of them have actually such a diagnosis substantiated. Moreover, the diagnostic approach to these problems is cumbersome and unsatisfactory, and the objectivation of a ...
Cantani A - - 1997
Peanut anaphylaxis is a potentially near-fatal or fatal disease complicated by the fact that peanuts as well as other food items are commonly used as an adulterant in the preparation of foods. A boy is reported with peanut allergy to demonstrate, presumably for the first time, that contact urticaria occasionally ...
Romano A - - 1997
BACKGROUND: Postprandial exercise-induced anaphylaxis (PPEIAn) is a form of EIAn in which the ingestion of food before the exercise is associated with the onset of symptoms. Skin reactivity and the presence of specific serum IgE to several food allergens suggest the occurrence of food-dependent allergic mechanisms. METHODS: In order to ...
Schrander J J - - 1997
Sixty children with juvenile chronic arthritis (JCA) have been examined at the paediatric rheumatology out-patient clinic in Maastricht, of whom three ultimately appeared to have a food intolerance.
