Abstract Introduction Pretreatment neurocognitive function may predict the treatment response to low-dose ketamine infusion in patients with treatment-resistant depression (TRD). However, the association between working memory function at baseline and the antidepressant efficacy of ketamine infusion remains unclear. Methods A total of 71 patients with TRD were randomized to one of three treatment groups: 0.5 mg/kg ketamine, 0.2 mg/kg ketamine, or normal saline. Depressive symptoms were measured using the 17-item Hamilton Depression Rating Scale (HDRS) at baseline and after treatment. Cognitive function was evaluated using working memory and go-no-go tasks at baseline. Results A generalized linear model with adjustments for demographic characteristics, treatment groups, and total HDRS scores at baseline revealed only a significant effect of working memory function (correct responses and omissions) on the changes in depressive symptoms measured by HDRS at baseline (F=12.862, p<0.05). Correlation analysis further showed a negative relationship (r=0.519, p=0.027) between pretreatment working memory function and changes in HDRS scores in the 0.5 mg/kg ketamine group. Discussion An inverse relationship between pretreatment working memory function and treatment response to ketamine infusion may confirm that low-dose ketamine infusion is beneficial and should be reserved for patients with TRD.

Abstract Background. The antidepressant effect of low-dose ketamine infusion on Taiwanese patients with anxious vs nonanxious treatment-resistant depression (ANX-TRD vs NANX-TRD) has remained unknown. Methods. In total, 71 patients with TRD were randomized to three groups. Each group had participants who received saline infusions mixed with 0 (a normal saline infusion), 0.2, and 0.5 mg/kg of ketamine. Participants were followed up for 2 weeks. Anxious depression was defined as major depressive disorder with a total score of 7 or more on the 17-item Hamilton Depression Rating Scale Anxiety-Somatization factor. Generalized estimating equation models were used to investigate the effects of treatment (ketamine vs placebo) and depression type (ANX-TRD vs NANX-TRD) in the reduction of depressive symptoms during the follow-up period. Results. Patients with ANX-TRD were less likely to respond to a single low-dose ketamine infusion than those with NANX-TRD. Among patients with NANX-TRD, low-dose ketamine infusion was significantly superior to placebo for reducing depressive symptoms. However, among patients with ANX-TRD, ketamine was not superior to placebo; nonetheless, approximately 30% of the patients responded to ketamine infusion compared to 13% who responded to the placebo. Conclusions. Low-dose ketamine infusion was effective for Taiwanese patients with NANX-TRD but not so effective for those with ANX-TRD. A higher level of anxiety severity accompanying depression was related to greater depression severity. This may confound and reduce the antidepressant effect of ketamine infusion.

AbstractKetamine produces a rapid antidepressant response in over 50% of adults with treatment-resistant depression. A long infusion of ketamine may provide durable remission of depressive symptoms, but the safety, efficacy, and neurobiological correlates are unknown. In this open-label, proof-of-principle study, adults with treatment-resistant depression (N = 23) underwent a 96-h infusion of intravenous ketamine (0.15 mg/kg/h titrated toward 0.6 mg/kg/h). Clonidine was co-administered to reduce psychotomimetic effects. We measured clinical response for 8 weeks post-infusion. Resting-state functional magnetic resonance imaging was used to assess functional connectivity in patients pre- and 2 weeks post-infusion and in matched non-depressed controls (N = 27). We hypothesized that responders to therapy would demonstrate response-dependent connectivity changes while all subjects would show treatment-dependent connectivity changes. Most participants completed infusion (21/23; mean final dose 0.54 mg/kg/h, SD 0.13). The infusion was well tolerated with minimal cognitive and psychotomimetic side effects. Depressive symptoms were markedly reduced (MADRS 29 ± 4 at baseline to 9 ± 8 one day post-infusion), which was sustained at 2 weeks (13 ± 8) and 8 weeks (15 ± 8). Imaging demonstrated a response-dependent decrease in hyperconnectivity of the subgenual anterior cingulate cortex to the default mode network, and a treatment-dependent decrease in hyperconnectivity within the limbic system (hippocampus, amygdala, medial thalamus, nucleus accumbens). In exploratory analyses, connectivity was increased between the limbic system and frontal areas, and smaller right hippocampus volume at baseline predicted larger MADRS change. A single prolonged infusion of ketamine provides a tolerated, rapid, and sustained response in treatment-resistant depression and normalizes depression-related hyperconnectivity in the limbic system and frontal lobe.ClinicalTrials.gov: Treatment Resistant Depression (Pilot), NCT01179009.

OBJECTIVE Depression resistant to standard treatment is devastating to an individual’s quality of life. Ketamine offers a safe and effective alternative to standard depression treatment, but many patients and providers are often unaware of this option. The American Association of Nurse Anesthetists and the American Psychiatric Nurses Association partnered in developing a collaborative approach to providing ketamine infusion therapy for psychiatric disorders. The purpose of this project was to disseminate information through an educational video about the safety and efficacy of outpatient low-dose ketamine infusions as an alternative therapy for treatment-resistant depression. METHODS A thorough literature review was conducted in PubMed, PsychINFO, CINAHL, and Google Scholar for articles describing the safety and efficacy of ketamine use in treatment-resistant depression. Based on the current research, an educational video reporting the benefits and safety of ketamine was developed and launched on two social media platforms—YouTube and Facebook—for individuals to view. The effectiveness of the video was evaluated through the number of views, likes, shares, and comments recorded. RESULTS At 9 months, 156 views, 60 likes, 8 shares, and 4 comments were recorded in both platforms. Comments indicated that viewers found the video informative and encouraging. CONCLUSIONS A short evidence-based educational video provides individuals with information regarding the safety and efficacy of low-dose ketamine infusions as an option for depression treatment. Ketamine outpatient clinics support and treat depressed patients who do not benefit from conventional pharmacologic medications.

Abstract:Objective:To assess the Patient Health Questionnaire (PHQ-9) as a predictor of relapse of depressive symptoms in treatment-resistant depression (TRD).Method:Analysis included maintenance phase data from SUSTAIN-1 (NCT02493868), a randomized, double-blind, active-controlled study in TRD patients that evaluated efficacy of intranasal esketamine (ESK) + oral antidepressant (AD) vs AD + intranasal placebo in delaying relapse of depressive symptoms. A ≥50% reduction in initial symptom score and total score of ≤12 were considered as response and remission, respectively, using the Montgomery-Asberg Depression Rating Scale. PHQ-9 total score (range, 0–27), PHQ-2 total score (0–6), and individual items of the PHQ-9 (0–3) were examined as predictors of relapse. Data were collected every 2 weeks. Association between time-varying PHQ-9 and event of depression relapse was evaluated in Andersen-Gill Cox model.Results:Of 176 stable remitters, 63 had a relapse event (ESK+AD [n=24]; AD+placebo [n=39]). Of 121 stable responders, 50 had a relapse event (ESK+AD [n=16]; AD+placebo [n=34]). Among stable remitters, PHQ-9 total score (HR; 95% CI [1.12; 1.04–1.21]) and PHQ-2 total score (1.58; 1.25–1.99) were associated with relapse risk. PHQ-9 items #1 (loss of pleasure, 2.07; 1.38–3.09), #2 (feeling down, 2.18; 1.51–3.15), #4 (feeling tired, 1.54; 1.13–2.11), and #6 (negative self-view, 2.27; 1.41–3.66) were associated with relapse risk. PHQ-2 total scale yielded the smallest Akaike’s Information Criterion among stable remitters and responders.Conclusion:PHQ-9, PHQ-2 total scores or individual items may be useful for predicting relapse of depressive symptoms among stable TRD patients.Funding Acknowledgements:This study was sponsored by Janssen Research and Development, LLC.

Synthetic Oxytocin

AbstractThe aim of this open trial was to assess the antidepressant/anxiolytic effects of oxytocin used as an adjunct to antidepressant in treatment-resistant depression. Fourteen patients, who have not responded to 40 mg of escitalopram, received intranasal synthetic oxytocin during 4 weeks, in association with antidepressant. This is the first open trial study suggesting OT in association with escitalopram significantly reduced scores on Hamilton Depression Rating Scale.
