[Relationship between cytochemical activity of leukocytes and autorosette formation phenomenon and its clinical significance in patients with leptospirosis].

The content of autorosettes in the peripheral blood forming from red cells round neutrophils and monocytes was found increased during the acute period of icterohemorrhagic leptospirosis. Autorosette-forming cells are characterized by a high activity of alkaline and acid phosphatases and low NBT-test values. The content of autorosettes directly correlates with the disease severity, bilirubin level, and presence of anemia. Assessment of autorosette-forming cells in patients with leptospirosis may be used as an additional test for evaluating the severity of intoxication, disease course, and for predicting the complications and disease outcome.
