title: Treatment of depression in first episode of schizophrenia: results from EUFEST.
abstract: Depressive symptomatology is an important target of treatment in first episode schizophrenia. This reanalysis of the European First Episode Schizophrenia Trial (EUFEST) describes the depressive symptomatology and the effect of antipsychotic treatment in patients suffering from first episode schizophrenia and schizophreniform disorder randomized to treatment with low dose haloperidol (n=103), amisulpride (n=104), olanzapine (n=105), quetiapine (n=104) or ziprasidone (n=82) for one year. At baseline, the mean score on the Calgary Depression Scale for Schizophrenia (CDSS) was 5.1 (±4.9) with 38.3% of patients having a CDSS score≥6, i.e. clinically relevant depressive symptom severity. During treatment depression scores decreased, the mean CDSS score being 1.1 (±2.1) and 3.0% of patients having a CDSS≥6 at 52 weeks. The proportion of patients using antidepressants during the complete trial was 18.5% in the haloperidol group, 28.6% in the olanzapine group compared to 5.8% in the quetiapine group, 12.5% in the amisulpride group, and 9.8% in the ziprasidone group. There were no differences over time in the probability of being depressed (CDSS≥6) between the 5 treatment groups after adjustment for antidepressant use, nor in a sub analysis of patients who did not take any antidepressant. Depression scores at baseline or during the trial had no effect on treatment discontinuation or on the reduction of positive symptoms. In summary, the results of EUFEST did not demonstrate a differential effect of the antipsychotics studied on depressive symptomatology in patients with first episode schizophrenia.
