Abstract

Only a few case reports of allergy to eggplant (Solanum melongena) have been reported. A relatively large number of individuals appear to experience food-related symptoms to eggplant in India. The major aims of this study are to assess the prevalence of food allergy to eggplant and analyse the age and gender distribution. Seven hundred and forty-one subjects (age range: 5-60 years) randomly selected from rural and urban areas of Mysore city were analysed for the prevalence of eggplant allergy based on case history, skin prick test (SPT) with eggplant extracts and allergen-specific IgE. The age and gender distribution for the prevalence of eggplant allergy and its association with other atopic conditions were assessed. Sixty-eight (9.2%) subjects reported adverse reactions to ingestion of eggplant, of which 32 (4.3%) subjects had positive history/positive SPT and 36 (4.9%) had positive history/negative SPT. Sixteen (2.2%) subjects had negative history/positive SPT. Ten subjects (1.4%) experienced allergic symptoms in <2 h. Sensitization to eggplant by SPT was more in atopic (16.7%) compared with non-atopic subjects (3.8%). All the SPT-positive subjects (n=48) underwent evaluation for eggplant allergen-specific IgE, which was det...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
