The Efficacy and Safety of γ-Linolenic Acid in the Treatment of Infantile Atopic Dermatitis

The efficacy and safety of γ-linolenic acid in the treatment of atopic dermatitis was evaluated. The children (mean age, 11.4 months) with atopic dermatitis (mean duration, 8.56 months) were openly treated with 3 g/day γ-linolenic acid, for 28 days. Clinical evaluations were carried out every 7 days, and parents were asked to keep a diary, recording details of symptoms of eczema every day. Blood chemistry and immunological tests were done before and after treatment. None of the children showed complete recovery of symptoms. A gradual improvement in erythema, excoriations and lichenification was seen; significant differences were shown for itching (P < 0.01), and the use of antihistamines (P < 0.01). A significant rise in the percentage of circulating CD8 was found. No side-effects were recorded. Dietetic and pharmacological approaches are the basis of the treatment of atopic dermatitis and γ-linolenic acid appears to be a safe and efficient additional therapy for infants and young children.
