RESUMEN
Tipo de estudio ensayo clínico controlado. Antecedentes la inmunoterapia consiste en la administración de extractos alérgicos en dosis crecientes con la finalidad de producir tolerancia. El extracto de giardia se viene utilizando en Cuba con estos fines en la urticaria crónica.

Objetivo:

valorar la eficacia de la inmunoterapia en pacientes con urticaria crónica sensibilizados a giardina. Materiales y

métodos:

se realizó punción cutánea con giardina en 146 pacientes con urticaria crónica de edades entre 15 y 60 años. A todos se les realizó punción cutánea con giardina. Los que el prick test fue positivo, a dicho extracto de giardias, se consideraron como grupo de estudio (n=70) y como grupo control los pacientes con prick test negativo (n=76). Se aplicó una pauta de inmunoterapia en el grupo de estudio durante un año. Ambos grupos recibieron tratamiento de rescate según brote y se llevó un control mensual de síntomas. Al año de seguimiento se evaluaron según las escalas curados, mejorados y sin respuesta y se valoraron las reacciones adversas a la inmunoterapia. La eficacia se estableció al comparar síntomas en los tratados y en los controles, antes y después del período de seguimiento y determinar la fuerza de asociación de la inmunoterapia.

Resultados:

del total estudiado, eliminaron los síntomas 86, mejoraron la frecuencia e intensidad de brotes 37 y se mantuvieron iguales 23. De los que recibieron inmunoterapia, el total de curados fue de 61 y de los que no recibieron la vacuna se curaron 35, para un RR = 0.13; IC 95 0.05, 0.31. Se concluye que la inmunoterapia con extracto de giardias, es clínicamente segura y eficaz al disminuir en forma significativa los brotes en piel en pacientes con urticaria sensibilizados con extracto de giardias.
ABSTRACT
Type of study controlled clinical trial. History immunotherapy consists in administering allergic extracts in growing doses with the purpose of producing tolerance. The extract of giardia has been used in Cuba with this purpose in the chronicle urticaria.

Objective:

to value the efficacy of the immunotherapy in patients with chronicle urticaria sensitized with giardia. Materials and

Methods:

146 patients with chronicle urticaria from 15 years to 60 years old were practiced cutaneous puncture with giardia.
