[Immunologic reactivity of patients with acute leukemia]

In sera of patients with acute leucosis the authors have determined antibodies to alpha-toxin, streptolysin-O, the complement, lysosyme. B-lysins and C-reactive protein. It was found that the indices of immune reactivity in patients with acute leucosis are dependent on a morphological variant of the disease, the duration of the conducted therapy and presence of complications. The most high immunity indices in patients with acute leucosis were observed in a primary active stage of the disease and during the period of remission. Considerable reduction of the immunity was noted in the terminal stage of the disease.
