| Description | Background: Selective IgA deficiency (IgAD) is the most common immunoglobulin deficiency with a variety of clinical manifestations. The frequency of IgAD differs depending on ethnic origin and clinical symptoms of investigated persons. Methods: The prevalence of IgAD (serum IgA level < 0.05 g/l) was determined in 5310 Czech blood donors, 10 326 patients underwent immunological investigation, and in 246 first degree -relatives of IgA deficient and common variable immunodeficiency (CVID) patients. Results: Selective IgA deficiency was detected in 13 (1: 408; 0.24%) of the blood donors. The prevalence of IgAD was increased both in children (48/3113; 1.5%) and adults (33/3824; 0.9%) referred for frequent respiratory tract infections (in both cases P< 0.001) compared to the healthy population. The frequency of IgAD was 12/189 (6%) in first degree relatives of IgAD patients, and 9/57 (16%) in relatives of CVID patients, with the highest frequency observed in children of CVID patients. Conclusions: The prevalence of IgAD in the Czech healthy population is comparable to other Caucasians. The frequency is increased in children with repeated respiratory tract infections and especially in relatives of patients with immunoglobulin deficiencies. |
