For some patients safe 20mg tadora erectile dysfunction treatment protocol, this postprandial exercise-induced anaphylaxis may occur with any food ingestion followed by exercise ( 156 buy tadora 20 mg cheap erectile dysfunction meaning,157). Others have exercise-induced anaphylaxis only associated with the ingestion of specific foods, such as celery ( 156) or shellfish (158). These patients are skin test positive to the foods, yet they have no allergic reactions unless ingestion is followed by or preceded by rigorous exercise ( 156,158). For all food-related exercise-induced anaphylaxis, episodes are prevented with avoidance of food ingestion 4 to 6 hours prior to or following exercise ( 157). Treatment also includes carrying self-injectable epinephrine, exercising with a buddy, wearing medic alert identification, and exercising only if a medical facility is in reasonable proximity. The mechanism of this type of anaphylaxis is not well understood, but it is thought to be mediated by mast cell degranulation (155). In one study, 132 patients who responded to a survey stating they had an adverse reaction to food additives underwent different oral challenges with additives mixed in combination and with placebo capsules. Of these patients, only 3 had a consistent reaction: 2 to the natural yellow-orange annatto and one to the azo dye and the antioxidants, for an overall prevalence of 0. There were no positive oral challenges with metabisulfite in 12 patients with idiopathic anaphylaxis, and 1 patient with chronic urticaria, all of whom had reactions temporally related to restaurant meals ( 161). Two multicenter trials were conducted to evaluate claims of hypersensitivity to aspartame. These were double-blind, placebo-controlled crossover trials, one involving 40 patients presenting with headache after aspartame ingestion and the other involving 21 patients with urticaria or angioedema associated with aspartame ingestion. Both studies reported that aspartame was no more likely than placebo to cause the adverse reactions ( 162,163). In a multicenter double-blind placebo-controlled trial of 120 individuals who believed they had reactions to monosodium glutamate, none had reproducible reactions ( 164). Other Other diseases that appear to be exacerbated by certain foods have been reported in the literature. Complaints of these as well as unusual clinical manifestations and excessive weight loss with elimination diets may all be manifestations of food aversion, possibly of a psychologic nature. Histories may more reliably implicate the offending agent in immediate-type reactions and may not be very helpful in chronic diseases such as atopic dermatitis ( 167). The physical examination may be helpful if a reaction is occurring and should also be used to rule out other disease processes. Data to gather in the evaluation of possible food allergy In eliciting a history, one must be aware of hidden foods, and be aware that ingredients that comprise less than 2% of a new product may not be listed on the package. Hidden foods may be foods included in processing, such as egg-white used in meat processing ( 168), or contamination of a safe food, either in preparation of the food or from shared equipment at a factory. Inulin, a fructan and storage carbohydrate, has recently been reported to cause anaphylaxis ( 169). This carbohydrate is found in more than 36,000 plants, including chicory and artichokes. This increased use is due to many postulated health benefits such as the ability to increase levels of enteric bacteria. Possible sources of hidden food allergy IgE-Mediated Reactions A variety of in vivo and in vitro testing can be performed to corroborate a suspected food allergy. Skin testing is recommended for histories suggestive of IgE-mediated food hypersensitivity. They are highly reliable ( 170) and give useful information in a short period of time (170,171). A drop of glycerinated food allergen extract (1:20 to 1:10 wt/vol dilution) is placed on the skin and the prick or puncture technique applied ( 171). Fruit and vegetable extracts are very labile, so fresh fruits and vegetables are recommended when testing for allergy to these foods ( 85). The food can be rubbed on the skin, which is then pricked, or the needle can first be introduced into the food with subsequent pricking of the skin. A wheal 3 mm greater than the negative control is considered a positive reaction ( 171). With reliable extracts, the incidence of false-negative results is low, rendering a negative predictive value of more than 95% ( 172). It is approximately 60% in a patient population in which the likelihood of food allergies is fairly high ( 172), but may be as low as 3% in a patient population in which the prevalence is low and there is no suggestive history ( 172). In this same population, however, the negative predictive value of the prick test for foods approaches 100% (172,173). Elimination diets are 7- to 14-day diets in which all foods suspected of causing an allergic reaction are eliminated. When multiple foods are suspected, the elimination diet may be repeated, with only several foods eliminated each time. This may be helpful in chronic conditions such as atopic dermatitis or in children in whom specific foods may be difficult to implicate. If there is no resolution of symptoms, the foods are thought not to be responsible. Foods that are implicated may be reintroduced one at a time at 24- to 48-hour intervals to determine which foods are responsible. Elimination diets rarely diagnose food allergies and can be very tedious and time consuming. In adults who are nutritionally healthy, a diet of rice, lamb, and water for several days can be useful to exclude food allergy as a cause for variety of chronic conditions such as urticaria or rhinitis. Diet diaries are occasionally useful when the cause-and-effect relationship are not initially perceived. Data of all foods ingested and any associated symptoms are recorded prospectively. Although there is no risk of nutritional inadequacies, these tend to yield little reward for the effort involved. Occupational food-induced respiratory allergies (allergic rhinoconjunctivitis or asthma) may require spirometry to document asthma. Many patients will only have symptoms in the workplace initially and may benefit from serial peak flow monitoring or even spirometry at the workplace ( 175). Bronchial allergen challenges may be used, but patients can have severe life-threatening bronchospasm so this should be done only in a medical setting capable of treating such reactions, and only if necessary. This test is less specific ( 172) than skin-prick tests, considerably more expensive, and yields less immediate results. It may be considered, however, in cases of severe atopic dermatitis or dermographism where skin testing is more difficult. In addition, it identified patients with a high likelihood (>95%) of reacting clinically to these foods ( 176).
