¿Qué es el síndrome alfa-gal y por qué se produce?

Síndrome de alfa-gal (AGS): una alergia alimentaria a la carne roja causada por una picadura de garrapata que desencadena una respuesta inmune al alfa-gal.

Reacción retardada: Los síntomas aparecen entre 3 y 6 horas después de consumir carne roja o productos que contienen alfa-gal.

Síntomas: Urticaria, picazón, hinchazón, dolor de estómago, diarrea, vómitos y anafilaxia.

Distribución geográfica: Se ha informado de AGS en EE. UU., Europa, Australia y otras regiones.

Factores de riesgo: Las actividades al aire libre, la exposición a garrapatas y la edad adulta aumentan el riesgo de desarrollar AGS.

Diagnóstico: Los análisis de sangre detectan anticuerpos alfa-gal para confirmar el AGS.

Tratamiento: Evitar la carne roja y los productos que contengan alfa-gal y controlar los síntomas con medicamentos.

Prevención: Prevenir las picaduras de garrapatas mediante ropa protectora, repelentes de insectos y controles regulares de garrapatas puede reducir el riesgo de AGS.
