An 8-week open-label trial of a 6-day course of mifepristone for the treatment of psychotic depression.

OBJECTIVE: Several investigations suggest that mifepristone leads to the rapid amelioration of psychotic depression. However, these studies were of short duration (1 week or less) and included subjects who were taking other psychotropic medications. The goals of this study were to extend these findings by conducting an 8-week trial of mifepristone for subjects with psychotic depression who were taking no concomitant psychiatric medications. METHOD: Twenty subjects with a DSM-IV major depressive episode with psychotic features (for convenience we use the term psychotic depression) taking no psychotropic medications were given a 6-day course of mifepristone and followed as inpatients for a total of 8 weeks. Nonblinded ratings using the Hamilton Rating Scale for Depression (HAM-D) and Clinical Global Impressions scale (CGI) were performed at baseline and at the end of weeks 1, 4, and 8. The Brief Psychiatric Rating Scale (BPRS) was also administered at baseline and after weeks 4 and 8. Subjects were recruited between February 2003 and December 2003. RESULTS: Significant improvements in HAM-D and CGI scores were shown after 1 week and between weeks 1 and 4 but not between weeks 4 and 8. BPRS scores improved significantly after week 4, while the improvement in BPRS scores between weeks 4 and 8 was of borderline significance. CONCLUSION: Mifepristone appears to be a useful intervention for psychotic depression, leading to significant improvements even after a 1-week course of administration. Issues related to its optimal dosing and to prediction of response are discussed, as are the implications of lack of a placebo group and the use of nonblinded ratings in the present study.

Sertraline as monotherapy in the treatment of psychotic and nonpsychotic depression.

BACKGROUND: Previous studies suggest that selective serotonin reuptake inhibitors (SSRIs) are effective when used alone in the treatment of unipolar depression with psychotic features. The purpose of the present study was to examine the response to sertraline for patients with and without psychotic features using standard criteria such as recovery and remission. METHOD: An 8-week open-label trial of sertraline in depressed inpatients was conducted. Twenty-five subjects had DSM-IV major depressive disorder with psychotic features, and 25 had DSM-IV major depressive disorder without psychotic features. After a 1-week open washout, all subjects were rated using the Hamilton Rating Scale for Depression (HAM-D) and Brief Psychiatric Rating Scale (BPRS) at baseline. The HAM-D was administered weekly, and the BPRS was administered again only at the end of the 8-week trial. Medication dosage was started at 50 mg/day, increased to 100 mg/day after 1 week, and then increased up to 200 mg/day if subjects had not remitted. RESULTS: Depressed patients without psychosis responded significantly better than did depressed patients with psychosis using the criteria of remission (HAM-D score - 7; p =.001), response (HAM-D score - 50% of baseline score; p =.011), referral for electroconvulsive therapy (HAM-D score >/= 15; p =.011), or change in HAM-D scores (p =.016). Baseline HAM-D score and psychosis independently predicted response, whereas baseline BPRS scores did not, regardless of whether psychotic status was entered into the analyses. CONCLUSION: Psychotic depression responds more poorly than depression without psychosis to sertraline alone. Psychosis was a predictor of response independent of degree of depression and general psychopathology. Limitations due to an open-label design are discussed, as are differences between this study and others using SSRIs for psychotic depression.
