[Immunotherapy using Giardia lamblia extract in recurrent chronic sensitized urticaria]. / Inmunoterapia con extracto de Giardia lamblia en la urticaria crónica recidivante sensibilizada.

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.

[Immunologic behavior in 50 patients with acute anterior uveitis]. / Comportamiento inmunológico en 50 pacientes portadores de uveítis anterior aguda.

A prospective study that included 50 patients with acute anterior uveitis was done. The aim was to describe their immunological behavior. According to the results, patients with an allergic basis are predisposed and have more severe disease. However, immunoallergic tests are positives in patients with acute anterior uveitis where associated pathologies modify the tests, even if allergic etiology may or may not be possible. We recommend further studies in patients with allergic antecedents, in order to pay more attention to them.
