ABSTRACT

Background:

Natural rubber latex allergy is an important health problem. Multiple contacts with latex in childhood are a risk factor. Many aspects of this disease are still unknown, one of which is the clinical outcome of these children. The aim of this study was to evaluate the clinical and epidemiological features of latex allergy and compliance with latex avoidance instructions in allergic children. Material and

methods:

Seventeen consecutive patients with a history of latex allergy, fruit allergy or chronic urticaria were selected. The patients underwent a skin prick test and determination of specific-IgE to latex at the start and at end of the study (median follow-up 3 years). At diagnosis, patients with a positive result to one of the tests and a clinical history of latex allergy were considered allergic; patients with a positive test but without a clinical history suggestive of allergy were considered sensitized. These children were given latex avoidance instructions.

Results:

Eleven children (64.7 %) were classified as allergic and 6 (35.3 %) as sensitized. Five patients had undergone latex-free surgery after diagnosis without incident. During follow-up, 11 patients (8 allergic and 3 sensitized) had contact with latex. Contact occurred in the home in 10 children, and all were symptomatic. Specific-IgE levels to latex at the end of the study were significantly higher in patients who had contact with latex during the follow-up period than in those without latex contact.

Conclusions:

Strict compliance with latex avoidance instructions is essential both inside and outside the hospital. Greater emphasis should be placed on reducing latex exposure in the home and school environments, as such contact could maintain positive IgE-antibody levels
RESUMEN
Antecedentes Un grupo de riesgo para la alergia al látex es la población infantil que presenta contactos sucesivos con este alérgeno desde edad muy temprana (intervenciones quirúrgicas de repetición). Aún se desconoce el patrón evolutivo de esta patología en esta población. Métodos y

resultados:

Se seleccionó a 17 pacientes con historia de alergia al látex, a frutas o urticaria crónica. Se realizó prueba cutánea y determinación de IgE específica frente a látex al inicio y al final del seguimiento. Al diagnóstico, los que presentaban alguna de las pruebas positivas con historia sugestiva de hipersensibilidad al látex fueron diagnosticados de alergia y quienes presentaban alguna prueba positiva, sin historia sugestiva, se consideraron sensibilizados. Se les realizaron indicaciones para la evitación de látex. Se diagnosticó a 11 pacientes como alérgicos (64,7%) y 6 (35,3%) como sensibilizados. Se intervino a 5 pacientes después del diagnóstico en quirófano libre de látex sin ninguna complicación. Durante el seguimiento, 11 pacientes (8 alérgicos y 3 sensibilizados) presentaron contactos con látex; 10 de ellos en el domicilio, y todos sintomáticos. La IgE específica frente a látex fue significativamente mayor al final del estudio en los pacientes que transgredieron con respecto a los que cumplieron la evitación (p = 0,007).

Conclusiones:

Se debe realizar un estricto control de las medidas de evitación en los niños alérgicos al látex en régimen hospitalario, pero consideramos necesario un esfuerzo para alcanzar un control igualmente estricto en el ambiente escolar y familiar de los niños de riesgo con el fin de reducir las transgresiones clínicas domiciliarias, responsables del mantenimiento de la sensibilización en algunos pacientes
