ALCAT Test results were the base for elimination diet treatment in several ailments regarded as the result of food allergy (intolerance) in 72 patients (45 children and 27 adults). The best results were achived in arthritis, urticaria, bronchitis, gastroenteritis (83%, 75%, 70% of improvement in treated patients respectively). Worse results ...
Bousquet J - - 1995
A positive food challenge doesn't imply that there is an IgE mediated allergy but implies the patient is intolerant to certain foods. If specific IgE and/or prick test to a specific food-stuff is positive, an IgE-mediated mechanism is likely to be involved but a proportion of patients with IgE to ...
Niggemann B - - 1994
To investigate the role of peripheral blood eosinophils and eosinophil cationic protein as parameters in monitoring oral food challenges, we monitored 25 infants and children with atopic dermatitis for up to 48 hours after 47 placebo-controlled oral food challenges with cow's milk, hen's egg, cow's milk and hen's egg, or ...

Recent evidence has demonstrated that neurogenic vascular headaches are a combination of neurological primary events and secondary vasomotor changes. The neurological events involve the hypothalamus and sensory cortex with sympathetic hypofunction and noradrenergic abnormalities. A platelet theory has been proposed but has not really been confirmed as a legitimate cause ...
Bahna S L - - 1994
Because food allergy treatment is basically avoidance of the offending food(s), identification of the latter becomes the cornerstone for management. At present, the elimination-challenge test is the most definitive procedure for verification of a cause-and-effect relationship between a particular food and a certain reaction, allergic or not. The oral challenge ...
Kaplan M S - - 1994
Two patients with clinically significant immunoglobulin E (IgE) mediated reactions to cow's milk which occur only under special circumstances are described. Although double-blind, placebo-controlled food challenges or open food challenges are generally very helpful, certain patients who react only under special circumstances might be missed when these office tests are ...
