Not all side-effects are undesirable side-effects of a treatment. Under certain conditions allergic side-effects during the therapy of phasic psychotics affect a turn in the course of the basic illness and bring a premature end to depression. As a result of the observation of a sudden cure of a deep vital depression in a 73 year old patient in direct chronological connection with the appearance of an allergic urticaria, studies were carried out, in the 8 years following, of a total of 18 cases of similar circumstances; during the treatment of an endogenous depression the development of intercurrent allergic skin reactions showed: in 6 cases the psychosis completely disappeared with the development of the urticaria; in 8 cases the symptoms were considerably relieved so that only the remains of vegetative disorders persisted; in 4 cases no effect could be determined. In 2 cases the same allergic reaction was consciously provoked by a reapplication of the medicaments concerned during a following depressive phase; again with favourable results since under these conditions coincidences are not very probable, the conclusion can be made, and experimentally supported, that allergic drug reactions may be employed in the course of depressions, with careful avoidance of complications.

The possible association between depression and type I allergies (i.e. immunoglobulin E-mediated hay fever, asthma, eczema, hives) was examined in a nonclinical sample of 379 college students. Measures included self-reports of depression, tiredness, fearfulness, allergic disorders, and environmental allergens and irritants. Seventy-one percent of the subjects who had ever received a professional diagnosis of depression also indicated a history of allergy: those with greater self-rated current depression overall reported a significantly higher prevalence of asthma (p less than 0.05). Type I allergic (43%) and nonallergic subjects did not differ in self-rated frequency of depression, fatigue, or anxiety. However, type I subjects reported significantly worse mood after the flu than did nonallergic subjects (p less than 0.001). The data support the hypothesis that individuals prone to clinical depression have more allergies than nondepressives. Allergics may experience more postflu mood worsening but not current depression in comparison with nonallergics.
