477 Autoimmunity in Patients with Allergy and Immunodeficiency: as Result of the Immune Chronic Inflammation

BACKGROUND: Autoimmunity is present in several patients that have allergy and immunodeficiency; however there are few reports that correlate these 3 immunological problems. Our objective was to study the association of these 3 problems where the deregulation of the T reg cells has a roll in triggering a chronic inflammation and the clinical expression. METHODS: We included 8 patients with symptoms of autoimmune disease, such as autoimmune hypothyroidism, dermatomiositis, systemic vasculitis, autoimmune uveitis, Wegener´s granulomatosis, antiphospholipid syndrome, Kawasaki´s disease and SLE with allergic disease and T and B lymphocytes immunodeficiency. We did the clinical history, skin test and also immunological evaluation with immunoglobulins, IgG subclasses, T lymphocytes absolute numbers and specific antibodies, all of them had diagnosis of allergy, with immunodeficiency and autoimmune disease. RESULTS: There were included 8 patients, with moderate to severe allergy and recurrent infections, from 3 to 66 years of age, 1 child (12.5%) and 7 adults (87.5%), 7 women (93.3%), 1 men (12.5%) with allergic rhinitis 8 (100%), combination of allergic rhinitis and other allergic disease 2 (25%), asthma 1 (12.5%), atopic dermatitis 1 (12.5%). Also all the 8 patients had humoral, cellular immunodeficiency and autoimmune problems, 7 of them received IVIG therapy on the basis of the immunodeficiency, with evident improvement, 1 did not received and had some improvement of their symptoms. CONCLUSIONS: We found out that the 8 patients with autoimmunity had allergy and also mixed T and B immunodeficiency. We conclude that the physicians should be aware of the correlation in chronic inflammation and the presence of the 3 immunological clinical problems to give appropriate treatment and improve the prognosis of these patients.
