title: [A 24-year-old patient with recurrent otolaryngologic infections].
abstract: An IgA deficiency is diagnosed in a 24-year-old patient with a long lasting history of otolaryngologic infections despite the fact that this history is more indicative for a common immunodeficieny. Even if the diagnosis of an IgA deficiency has normally no specific therapeutic consequences, it is important to identify this disorder because it is associated with a higher incidence of allergic reaction during treatment with blood products and can also evolve into a common variable immunodeficiency.
