Abstract:
A study of 100 patients with chronic urticaria by Giardia lamblia parasitic infection were reviewed. The urticaria had been resistant to antihistamine, corticosteroid and antiparasitic therapy. An urticaria evaluation included CBC, immunoglobulins M, G, A and E determinations, and stool examination, bile drainage and duodenal smear for ova and parasites. A prick test with Giardia's allergen 1, 10 and 100 UNP dilutions were realized. We found a 93% improvement in clinical symptoms using allergy immunotherapy with Giardia's antigen preparation associated to treatment.
