Intrinsic asthma, defined as asthma which is not from allergy to pneumo-allergens, of cause unknown, may show several etiologies. Allergics, remembering that there in some subjects there may be small amounts of IgE on the mastocytes, with specific RAST IgE negative, skin tests only weakly positive, but with a positive provocation test to pneumo-allergens. Food allergy, isolated and associated, may also contribute a not-negligible cause. Non-allergics, responding to the frequent triggering factors: Gastro-oesophageal reflux; Neuro-endocrine origin; Infections; Physical origin (exercise). In our study, we quote two types of extremely severe asthma, linked to intolerance to aspirin and metabisulfites with others that are associated.
