[Lymphocyte populations in the peripheral blood of patients with various types of bronchial asthma].

By the aid of rosette techniques (Etotal-, early-, stable-, active-, avid-, mouse-erythrocyte-rosettes) different populations of lymphocytes in peripheral blood from 68 patients with Asthma bronchiale (20 exogen-allergic, 17 infect-induced, 16 mixed-type, 15 non-classifiable) were investigated. The total number of lymphocytes was reduced, exceptionally in cases of infect-induced Asthma bronchiale. The number of T-cells was reduced in the exogen-allergic, infect-induced type and especially in the mixed-type of Asthma bronchiale, whereas the number of B-cells did not differ from the normal values (30 healthy persons). Within the population of T-cells the number of so-called active rosettes was slightly diminished in exogen-allergic and significantly decreased in infect-induced and mixed-types. Relations between immunodeficiency and Asthma bronchiale are discussed.
