[Clinical aspects of IgA deficiency]

The authors have carried out a retrospective study of 33 selective IgA-deficient patients. They have found the high frequency of respiratory infections, gastrointestinal (celiac disease, giardiasis), and also autoimmune-, allergic- and malignant diseases. They have called the attention to the variety of the clinical picture, the possible consequences of the haemo- and immunotherapy, as well as to the importance of the early diagnosis and examination of family members.
