Elevated blood neutrophil concentration in mania.
Total, differential, and absolute blood cell counts were compared in 66 untreated manics and 178 untreated schizophrenics. Mania was associated with significantly higher total leukocyte counts (p less than .001), accounted for by a significant increase (p less than .0001) in the number of neutrophils. There were no significant differences between the two groups in any other blood cell elements. Using normative values, manic patients had significantly higher frequencies of both leukocytosis (25.8% vs. 12.4%) and neutrophilia (34.8% vs. 12.4%) than the schizophrenic group. These data suggest a significant association between leukocytosis, neutrophilia, and mania.
