Elevated serum levels of lactoferrin and eosinophil cationic protein in schizophrenic patients
R Hallgren, P Venge and B Wistedt
The serum levels of lactoferrin, eosinophil cationic protein (ECP),
lysozyme and beta 2-microglobulin have been measured in schizophrenic
patients in an attempt to elucidate the activity and turnover of neutrophil
and eosinophil granulocytes, macrophages/monocytes and lymphocytes,
respectively. Serum-lactoferrin and serum-ECP levels were significantly (P
less than 0.001) higher in the patient group as compared to healthy
controls in contrast to blood cell counts and serum- lysozyme and serum-
beta 2-microglobulin levels which all were within normal limits. The
results were not affected by anti-psychotic therapy. A significant
correlation was found between serum-ECP and serum- lactoferrin levels which
may suggest a common underlying cause of the elevated levels. The findings
suggest an increased eosinophil and neutrophil activity and/or turnover in
schizophrenia and may have a bearing on the well-known altered inflammatory
response associated with this syndrome.
