title: Antigen-free diet in adult patients with atopic dermatitis. A double-blind controlled study.
abstract: The efficacy of an antigen-free diet on the activity of atopic dermatitis was examined in a double-blind study, comprising 33 adults with severe atopic dermatitis. The antigen-free diet (Vivasorb) was compared to a placebo diet during three weeks of hospitalization. Twenty-five patients were evaluable, two of whom had their diet stopped after a few days due to exacerbation. Nine patients improved, while 16 patients were unchanged. Among those who improved five patients had Vivasorb and four placebo diet. In the remaining group 11 patients had Vivasorb and five had placebo. Four patients reported of less pruritus, sleeplessness and antihistamine consumption (three Vivasorb, one placebo) while 21 did not (13 Vivasorb, eight placebo). Thus, there were no significant differences between the groups. Paraclinical studies of circulating eosinophilocytes, serum IgE, orosomucoid, HLA-antigens, and immunofluorescence of skin biopsies showed no differences between the Vivasorb and the placebo groups. The results from the examination of this relatively small number of patients suggest that elementary intolerance plays little role in the etiology of atopic dermatitis in adults.
