[Leukocytosis, the leftward shift of the white blood picture and leukemoid reactions in the internal medicine clinic].

The white blood count of 6549 patients with various internal diseases of respiratory, cardiovascular, gastrointestinal, excretory and endocrine systems was studied as well as in neoplasms, collagenosis, etc. with the exception of malignant hemopathies. Leukocytosis was established in 21.8% of them. In almost half of the cases, leukocytosis is low, in 44.6% it ranges from 12-20 X 10(9)/l and in 10.2%--it is high--from 20 to 40 X 10(9)/l. Immature cells in the peripheral blood were established corresponding to stab neutrophils over 0.06-0.10, metamyelocytes, myelocytes reaching myeloblasts in the cases with leukemoid reactions. The leukemoid reactions have, with no exceptions, been of myeloid type and developed in various diseases.
