title: [Drugs as risk factors of food anaphylaxis in adults].
abstract: Anaphylaxis is the most severe type of food allergy. Factors of risk are advanced age, cardiopathy, asthma, mastocytosis. Age may be linked to an increased consumption of drugs: aspirin, nonsteroidal anti-inflammatory drugs, beta-blockers, inhibitors of angiotensin converting enzyme (ACE). A case-control study comparing anaphylaxis and mild food allergies has shown a sharp increase of consumption of these drugs in patients with anaphylaxis, with odds ratio respectively of 10.8 [CI 95%: 3.10-41.3], 8.2 [CI 95%: 1.37-62.51], 6.8 [CI 95%: 1.78-27.78] and 13 [CI 95%: 1.34-310.38]. Besides, exercise potentiates the relative risk of drug consumption. Predominant mechanisms could be an increase of gut permeability enhancing the passage of food allergens in the mucosa and in blood, and the inhibition of ACE, so that the angiotensin homeostatic mechanism deteriorates. Main sites of interference may be endothelium and gut epithelium. Preventive measures excluding the intake of aspirin and nonsteroidal anti-inflammatory drugs before the meals can be recommended for food allergic and food sensitized adults. Treatment of hypertension can address to other families of drugs than ACE inhibitors (ACEI) and beta blockers. The benefit-risk ratio of beta blockers and ACEI has to be carefully considered in the case of cardiopathy. double dagger.
