Nefazodone treatment of dysthymic disorder an open, long-term, prospective pilot study.

Abstract
Dysthymic disorder, described by the Diagnostic and Statistical Manual of Mental Disorders--4th edition (DSM-IV) criteria as a chronically depressed mood that occurs most of the day more days than not for at least 2 years and has a lifetime prevalence rate of approximately 3.3% [Gwirtsman, 1994. Psychopharmacol. Bull. 30 (1994) 45.]. This disorder, which is disabling, often goes unrecognized and its sufferers are often undertreated, but recent evidence has suggested that people with dysthymia may respond to antidepressant treatment. Based on effective outcomes in previous studies using fluoxetine (a 5-HT reuptake inhibitor) and ritanserin (a 5-HT2A antagonist), it was hypothesized that nefazodone, which is both a serotonin (5-HT) reuptake inhibitor (rather weak) and a 5-HT2A receptor antagonist, may provide an effective treatment for patients with dysthymic disorder. Six participants completed this 24-week pilot trial. A decrease in the Hamilton Rating Scale for Depression (HAM-D) scores was observed from baseline to Week 24, although most changes occurred in the first 4 weeks of participation. There was an improvement in anxiety symptomatology, both physiological and psychological. General functioning did not improve as observed by Global Assessment of Functioning Scale (GAF) scores. There may be some benefit to nefazodone for treatment of dysthymia, as indicated by positive results on HAM-D, Hamilton Anxiety Scale (HAM-AD), and Hopkins Symptom Checklist (HCL) scores within the first 4 weeks; however, it is possible that such dramatic results may be due to entry into the study alone, and not to medication.
