Ketamine Therapy for Treatment-resistant Depression in a Patient with Multiple Sclerosis: A Case Report.

ABSTRACT: Objective: Depression is a common condition among patients with multiple sclerosis and often becomes resistant to oral antidepressants. We report a patient with multiple sclerosis who developed severe treatment-resistant depression and who was successfully treated with intravenous ketamine over the period of two years. Methods: Ketamine treatment protocol included an initial series of six treatments administered every other day, followed by a maintenance schedule. Ketamine was administered intravenously at 0.5mg/kg of ideal body weight over 40 minutes. Depression symptoms were measured using Beck Depression Index. Results: The patient's Beck Depression Index score prior to initiating ketamine treatment was 38, corresponding to severe depression. Response to treatment, defined as 50-percent reduction in Beck Depression Index score, was observed after five treatments. For this patient, the maintenance schedule ranged from a weekly treatment to one treatment every three weeks. During the two-year observation period, this patient was able to maintain a stable non-depressed mood and had no worsening of her MS symptoms. Conclusion: Ketamine may be an alternative treatment for resistant depression and may have a special use in patients with multiple sclerosis.

Project description:OBJECTIVE:The N-methyl-D-aspartate receptor antagonist ketamine has rapid antidepressant effects in treatment-resistant major depressive disorder (MDD) and bipolar depression. Clinical predictors may identify those more likely to benefit from ketamine within clinically heterogeneous populations. METHOD:Data were analyzed from 4 studies of treatment-resistant inpatients with DSM-IV-TR-diagnosed MDD or bipolar I or II depression. Patients who were currently experiencing a moderate-to-severe major depressive episode were enrolled between November 2004 and March 2013. All subjects received a single subanesthetic (0.5 mg/kg) ketamine infusion over 40 minutes. Patients were analyzed at the 230-minute postinfusion time point (n = 108), at day 1 (n = 82), and at day 7 (n = 71). Univariate Pearson correlations were performed for each variable with percent change from baseline in the 17-item Hamilton Depression Rating Scale (HDRS). Multivariate linear regression was then conducted for statistically significant predictors (P ? .05, 2-tailed). RESULTS:Higher body mass index correlated with greater HDRS improvement at 230 minutes (standardized ? = -0.30, P = .004) and at day 1 (standardized ? = -0.37, P = .001), but not at day 7 (standardized ? = -0.18, P = .10). Family history of an alcohol use disorder in a first-degree relative was associated with greater HDRS improvement at day 1 (standardized ? = -0.27, P = .014) and day 7 (standardized ? = -0.41, P < .001). No prior history of suicide attempt(s) was associated with greater improvement only at day 7 (standardized ? = 0.28, P = .01). The overall statistical model explained 13%, 23%, and 36% of HDRS percent change variance at 230 minutes, day 1, and day 7, respectively. CONCLUSIONS:Despite its post hoc nature, this study identified several clinical correlates of ketamine's rapid and durable antidepressant effects. Further investigation of these relationships is critical for individualized treatment of depression.
