Ridolo E, Barone A, Ottoni M, Peveri S, Montagni M, Nicoletta F. Factors and co-factors influencing clinical manifestations in nsLTPs allergy: between the good and the bad. FRONTIERS IN ALLERGY 2023; 4:1253304. [PMID: 37841053 PMCID: PMC10568476 DOI: 10.3389/falgy.2023.1253304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 09/18/2023] [Indexed: 10/17/2023] Open
Abstract
Non-specific lipid transfer proteins (nsLTPs) are a family of plant pan-allergens that represent the primary cause of food allergies in the Mediterranean area, characterized by a wide range of clinical manifestations, ranging from the total absence of symptoms up to anaphylaxis. This wide variety of symptoms is related to the intrinsic capacity of nsLTPs to cause an allergic reaction in a specific subject, but also to the presence of co-factors exacerbating (i.e., exercise, NSAIDs, PPIs, alcohol, cannabis, prolonged fasting, menstruation, acute infections, sleep deprivation, chronic urticaria) or protecting from (i.e., co-sensitization to PR10, profilin or polcalcin) severe reactions. In this picture, recognizing some nsLTPs-related peculiarities (i.e., route, type and number of sensitizations, concentration of the allergen, cross-reactions) and eventual co-factors may help the allergist to define the risk profile of the single patient, in order to promote the appropriate management of the allergy from dietary advices up to the prescription of life-saving epinephrine autoinjector.

Clin Mol Allergy 2023; 21:3.

Abstract
BACKGROUND Non-specific lipid-transfer protein (nsLTP) is a pan-allergen in the plant world, and a cause of significant concern as food allergen in the Mediterranean area, due to its general heat- and acid-resistance and hence the risk of severe allergic reactions. Pru p 3, the peach nsLTP, is considered the primary sensitizer to this allergen family and this allergy is usually persistent. Allergen-free diet and acute treatment of manifestations are the main recognized management goals in food allergy. MAIN TEXT The role of immunotherapy for treating food allergy in adult patients is controversial, but immunotherapy for Pru p 3 could potentially represent a relevant therapeutic strategy. We systematically searched databases for studies assessing the role of immunotherapy Pru p 3 in food allergy. Overall, nine studies were included. Immunotherapy with Pru p 3 appears to be effective and with a good safety profile in both peach and LTP allergy for some foods, such as peanut, in both RCT and real-life studies. CONCLUSIONS Immunotherapy with Pru p 3 is a possible treatment option for food allergy to the peach LTP in the Mediterranean area, although at present have not reached routinary clinical practice. Larger studies are needed to confirm these findings and identify predictive biomarkers.

Abstract
Peach allergy is emerging as a common type of fresh-fruit allergy in Europe, especially in the Mediterranean area. The clinical manifestations of peach allergy tend to have a peculiar geographical distribution and can range from mild oral symptoms to anaphylaxis, depending on the allergic sensitization profile. The peach allergen Pru p 7, also known as peamaclein, has recently been identified as a marker of peach allergy severity and as being responsible for peculiar clinical features in areas with high exposure to cypress pollen. This review addresses the latest findings on molecular allergens for the diagnosis of peach allergy, the clinical phenotypes and endotypes of peach allergy in adults and children, and management strategies, including immunotherapy, for peach allergy.

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.
