Selective IgA Deficiency a Probable Risk of Recurrent Chest Infections in Asthmatics.

Background: Selective immunoglobulin A (IgA) deficiency is characterized by a high incidence of both recurrent infections and atopic diseases. Asthma is one of the most common lung diseases affecting around 300 million people worldwide and is associated with risk of serious pneumococcal disease and microbial infections. Multiple studies have attributed this to impaired innate and adaptive immunity in asthmatics.

Study of selective immunoglobulin A deficiency among Egyptian patients with food allergy.

Introduction: IgA deficiency is one of the commonest primary antibody deficiencies. Although many affected individuals could be asymptomatic, selected patients suffer from recurrent mucosal infections, allergies, and autoimmune diseases.

Aim Of The Study: To investigate the prevalence of IgA deficiency among Egyptian patients with food allergy.
