What is food allergy?
Foods, whether natural or modified, and additives can cause adverse reactions to the person who ingests or comes into contact with them. A large number of these reactions are due to an immunological reaction between the proteins in the food and the specific antibodies produced by the person with a food allergy. Occasionally, adverse reactions or food intolerance can occur without the cause being allergy (toxicity, enzyme deficiency in the person ingesting the food, etc.).
Food allergy is very common in childhood (affecting 10-15% of the population), while in adulthood it is much less frequent (less than 2%).
- ¿Cómo se manifiesta la alergia a alimentos?
En la alergia alimentaria mediada por la inmunoglobulina E (IgE) la reacción se produce a los pocos minutos de haber ingerido, tocado e inclusive inhalado el alimento desencadenante de la reacción. Los síntomas pueden variar: desde un simple picor y rojez alrededor de la boca hasta una reacción grave con edema de boca y de lengua, vómitos, dolor abdominal, diarreas, asma, urticaria. Existe el riesgo de una anafilaxia que pone en peligro la vida del paciente.
Los alimentos responsables de la alergia pueden ser muy diversos. En los lactantes tiene gran importancia la hipersensibilidad a la leche de vaca y al huevo. Otros alimentos alergénicos son los frutos secos, el marisco y pescado, cereales y frutas.
La intolerancia al gluten (proteínas presentes en algunos cereales comunes) ocasiona la enfermedad celíaca que no es una alergia a alimentos.
- ¿Cómo se diagnostica la alergia a alimentos?
Es muy frecuente que el propio paciente o los padres del niño detecten la reacción y el alimento que probablemente la produce. Muchos niños pequeños rechazan de forma absoluta la ingestión de algunos de estos alimentos.El especialista debe realizar una historia clínica sistemática y exhaustiva para orientar el diagnóstico alergológico. Si la edad del niño lo permite, se realizarán pruebas cutáneas del "prick" o bien análisis de sangre para determinar los marcadores de alergia (IgE total) y los anticuerpos IgE o IgG específicos para el alimento o alimentos sospechosos.
Una vez establecido el diagnóstico de alergia alimentaria, debe procederse a una eliminación del mismo de la dieta, con la cual los síntomas deben retroceder. En caso de duda puede procederse a la reintroducción controlada y progresiva del alimento que quiere estudiarse y comprobar si los síntomas se repiten o no.
- ¿Cuál es el tratamiento de la alergia a alimentos?
El único tratamiento más efectivo es evitar el alimento causante de la alergia. Los pacientes y padres de niños afectados deben revisar con atención las etiquetas de los alimentos que han de ingerir. Es muy importante una vigilancia especial en restaurantes y comidas colectivas.
En niños que han practicado la exclusión de la leche y el huevo, al cabo de años y después de revisar los resultados de las pruebas y análisis, puede reintroducirse progresivamente el alimento y en muchos casos se alcanza una tolerancia adecuada.
En caso de ingestión accidental del alimento que provoca la alergia, puede ser necesaria la administración de antihistamínicos, corticoides e inclusive de adrenalina inyectable.
En la actualidad se dispone de una vacuna de administración local (sublingual) para las proteínas del melocotón - durazno en Canarias y sudamerica- (Prunus pérsica) que en casos de reacciones muy severas (anafilaxia) permite alcanzar un grado importante de desensibilización.
