Elevated blood neutrophil concentration in mania.

Area of Science:

• Hematology
• Psychiatry
• Immunology

Background:

• Blood cell counts can be altered in psychiatric conditions.
• Understanding these differences may offer diagnostic or prognostic insights.

Purpose of the Study:

• To compare blood cell counts in untreated manic and schizophrenic patients.
• To identify specific hematological differences associated with mania.

Main Methods:

• Compared total, differential, and absolute blood cell counts.
• Analyzed data from 66 untreated manic and 178 untreated schizophrenic patients.

Main Results:

• Manic patients had significantly higher total leukocyte counts (p < .001).
• This increase was driven by a significant rise in neutrophils (p < .0001).
• Manic patients exhibited higher frequencies of leukocytosis and neutrophilia.

Conclusions:

• A significant association exists between leukocytosis, neutrophilia, and mania.
• These hematological findings may serve as potential biomarkers for mania.
