Abstract

The Solanaceae family, including, among other, eggplants, represents the sixth most widely cultivated crops around the globe. We review the current data regarding allergies to Solanum melongena (eggplants), generating symptoms that range from gastrointestinal to respiratory allergic reactions. Currently, there are more than 4 mechanisms and molecules presumably involved in triggering allergic reactions to Solanum melongena: The lipid transfer protein (LTP) pathway, the profilin pathway, polyphenol oxidase (PPO) mechanism and other molecules. Allergies may be triggered both by pollen respiratory reactions and fruit intake. There is also an important cross-reactivity mechanism revealed by recent studies. Our literature review revealed many case series studies, some with in-depth molecular analysis of the triggering mechanism. However, wide population studies are still scarce. Current geographical distribution of the crops and population migrations should enhance the awareness of allergy and immunology specialists, ENT specialists, emergency physicians and pediatricians to the need for proper routine laboratory testing for possible Solanum allergy.
