ABSTRACT
Background and

Objectives:

Lipid transfer protein (LTP) sensitization is the most common cause of food allergy in the Mediterranean area, with peach allergy acting as the primary sensitizer in most cases. Lettuce has been described as a common offending food in patients with LTP syndrome. The aim of the study was to investigate the frequency and clinical expression of LTP syndrome in a sample of lettuceallergic patients.

Methods:

We determined specific IgE to Pru p 3 and lettuce in a sample of 30 patients with a diagnosis of lettuce allergy. Symptoms elicited by other LTP-containing plant-derived foods and the presence of cofactors were assessed.

Results:

The clinical symptoms of lettuce allergy were frequently severe, with 18 of the 30 patients experiencing anaphylaxis. All the patients had allergic reactions to other plant foods. Cofactors were involved in the clinical reactions of 13 of the 30 patients. Sensitization to pollens was found in 90% of patients.

Conclusions:

Lettuce allergy is found not as an isolated condition but in the context of LTP syndrome and it is characterized by severe reactions and frequent cofactor association (AU)
RESUMEN
Introducción y

Objetivo:

La sensibilización a la LTP es la causa más frecuente de alergia alimentaria en el área mediterránea, siendo la alergia al melocotón el sensibilizador primario en la mayoría de los casos. La alergia a la lechuga ha sido descrita como un manifestación frecuente en los pacientes que sufren síndrome de LTP. El objetivo del estudio fue investigar la frecuencia del síndrome de LTP en una muestra de pacientes alérgicos a lechuga y evaluar su patrón clínico.

Métodos:

Se determinó la IgE específica a Pru p 3 y a lechuga en una muestra de 30 pacientes con un diagnóstico de alergia a la lechuga. Se evaluaron los síntomas con otras LTPs de alimentos de origen vegetal y la presencia de cofactores.

Resultados:

Los síntomas clínicos de la alergia a lechuga fueron frecuentemente graves, ya que 18/30 pacientes experimentaron anafilaxia. Todos los pacientes experimentaron reacciones alérgicas a otros alimentos vegetales. En 13/30 pacientes, los cofactores estaban implicados en las manifestaciones clínicas. Se observó que el 90% de los pacientes estaban sensibilizados a pólenes.

Conclusiones:

La alergia a la lechuga más que de forma aislada, ocurre en el contexto del síndrome LTP y se caracteriza por su frecuente asociación a cofactores y la gravedad de sus reacciones (AU)
