Abstract

Background

We wished to investigate central serotonergic function in untreated schizophrenia.

Method

Thirteen drug-naive, DSM–III–R schizophrenic patients were compared with sex, race, age, weight and menstrual phase matched controls. Plasma prolactin and cortisol responses to a specific serotonergic probe, d-fenfluramine, were measured along with BPRS ratings.

Results

Prolactin responses were enhanced in schizophrenic patients compared to controls (P < 0.05) and were correlated positively with BPRS items for depression, anxiety and guilt. Baseline cortisol was also raised in those with schizophrenia (P < 0.001).

Conclusions

Central serotonergic tone may be raised in acute, drug-naive schizophrenia and may be associated with the presence of affective symptomatology.
