P0099 - Treatment of post-psychotic depression (PPD) in schizophrenia

Abstract

Background:

Depression accompanied acute psychosis in 70% of cases and remitted in line with the psychosis; 36% developed PPD without a concomitant increase in psychotic symptoms. PPD occurs without concomitant change in positive or negative symptoms.

Aims:

We try to evaluate efficacy of Fluvoxamine, versus efficacy of mirtazapine and venlafaxine in PPD.

Method:

25 patients (17 men, 8 female), aged 18-45 years, diagnosed with schizophrenia and PPD by DSM IV criteria. All patients received a second generation of antipsychotic (SGA) .We divided in 3 groups - A (9 patients) treated with SGA + Fluvoxamine (100 mg/day), group B (8 patients) treated with SGA + mirtazapine (30-45mg/day) and group C (8 patients) treated with SGA + venlafaxine (150- 225mg/day). We use BPRS, HAMD, and CGI for severity. Period of study 2 month, with visit at every week. We evaluate efficacy in group A versus efficacy in group B and C.

Results:

in group A: 2 drop-out, 6 responders, 1 non-responders; in group B: 1 drop- out, 6 responders, 1 non- responders, in group C: 1 drop- out, 7 responders. The response was faster in group C. The treatment was well tolerated.

Conclusions:

The results were similar in all groups, but the most responders were found in patients with family support, in first 3 years of evolution of schizophrenia, with family history of affective disorders, absence of negative symptoms. The response was better at patients who don't have traumatic stress in there children or adolescent period.
