Four methods of treatment are available in cases of protein allergy: elimination of the allergen from the environment or the food of the patient; desensitization by specific protein treatment; desensitization by nonspecific protein, and treatment of the symptoms, usually by means of drugs. The last method gives temporary relief and is useful in emergencies only. Desensitization by injection is frequently unsuccessful1 and is always attended by some danger.2 In cases of food allergy, Duke3 considers injections of specific proteins justified only in cases in which the allergen is a common food which cannot be eliminated from the diet easily; he considers nonspecific protein therapy justified only in case the cause of illness cannot be found or removed. Desensitization by oral administration of the offending food gives irregular, unsatisfactory results.4
Elimination of the food or foods to which the patient is sensitive is the method of control
