title: CSF creatinine in schizophrenia.
abstract: Concentrations of creatinine in cerebrospinal fluid (CSF) from schizophrenic patients and healthy control subjects were determined by a liquid chromatographic method. The concentration of creatinine in CSF from schizophrenic patients was lower (42.8 nmol/ml) than that of the controls (54.4 nmol/ml). The concentration of creatinine was correlated to the levels of homovanillic acid and 5-hydroxyindoleacetic acid. Treatment of the schizophrenic patients with sulpiride (800 mg daily), but not with chlorpromazine, elevated the concentration of creatinine in the CSF.
