Changes in serum copper concentration are observed in patients with depressive symptoms. Unmet needs in contemporary antidepressant treatment have increased interest in non-monoaminergic antidepressants, such as ketamine, an anaesthetic drug that has demonstrated a rapid antidepressant effect in patients with treatment-resistant depression (TRD). The purpose of this study was to examine whether serum copper concentrations change during ketamine treatment and whether there is an association between the copper concentrations and treatment response measured using psychometric scale scores. Moreover, the interlink between somatic comorbidities and copper concentration was studied. Patients with major depressive disorder or bipolar disorder were rated weekly by a clinician using the Montgomery–Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS). Copper level assessments were carried out weekly before the start of ketamine treatment and then after every second infusion and one week after the last ketamine infusion. The serum concentration of copper before ketamine treatment was significantly higher than that after the fifth infusion (p = 0.016), and the serum concentration after the treatment was significantly higher than that after the fifth infusion (p = 0.048). No significant correlations between changes in the copper serum concentrations and MADRS or YMRS were found. The serum copper level was not associated with somatic comorbidities during the course of treatment. This study provides data on the role of copper in short-term intravenous ketamine treatment in TRD, although no clear evidence of a connection between the copper level and treatment response was found.

AbstractApproximately one-third of patients with major depressive disorder (MDD) have treatment-resistant depression (TRD). The TRAL study will evaluate the prevalence and impact of TRD among patients with MDD in four Latin American countries. In this multicenter, prospective, observational study, patients with MDD were recruited from 33 reference sites in Mexico, Colombia, Brazil, and Argentina. Patients were assessed for TRD, defined as failure to respond to ≥ 2 antidepressant medications of adequate dose and duration. Demographics, previous/current treatments, depressive symptoms, functioning, healthcare resource utilization, and work impairment were also collected and evaluated using descriptive statistics, chi-square test, Fisher exact test, t-test for independent samples, or the Mann–Whitney nonparametric test, as appropriate. 1475 patients with MDD were included in the analysis (mean age, 45.6 years; 78% women); 89% were receiving relevant psychiatric treatment. 429 patients met criteria for TRD, and a numerically higher proportion of patients with TRD was present in public versus private sites of care (31% vs 27%). The mean Montgomery-Asberg Depression Rating Scale score was 25.0 among all MDD patients and was significantly higher for patients with TRD versus non-TRD (29.4 vs 23.3; P < 0.0001). Patients with TRD, versus those with non-TRD, were significantly more likely to be older, have a longer disease duration, have more comorbidities, be symptomatic, have a higher median number of psychiatric consultations, and report greater work impairment. Patients with TRD have a disproportionate burden of disease compared to those with non-TRD. Appropriate treatment for TRD is a substantial unmet need in Latin America. https://www.ClinicalTrials.gov identifier NCT03207282, 07/02/2017.

AbstractBackgroundRecent open-label trials show that psychedelics, such as ayahuasca, hold promise as fast-onset antidepressants in treatment-resistant depression.MethodsTo test the antidepressant effects of ayahuasca, we conducted a parallel-arm, double-blind randomized placebo-controlled trial in 29 patients with treatment-resistant depression. Patients received a single dose of either ayahuasca or placebo. We assessed changes in depression severity with the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Hamilton Depression Rating scale at baseline, and at 1 (D1), 2 (D2), and 7 (D7) days after dosing.ResultsWe observed significant antidepressant effects of ayahuasca when compared with placebo at all-time points. MADRS scores were significantly lower in the ayahuasca group compared with placebo at D1 and D2 (p= 0.04), and at D7 (p< 0.0001). Between-group effect sizes increased from D1 to D7 (D1: Cohen'sd= 0.84; D2: Cohen'sd= 0.84; D7: Cohen'sd= 1.49). Response rates were high for both groups at D1 and D2, and significantly higher in the ayahuasca group at D7 (64%v.27%;p= 0.04). Remission rate showed a trend toward significance at D7 (36%v.7%,p= 0.054).ConclusionsTo our knowledge, this is the first controlled trial to test a psychedelic substance in treatment-resistant depression. Overall, this study brings new evidence supporting the safety and therapeutic value of ayahuasca, dosed within an appropriate setting, to help treat depression.

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.

Objective:To review the pharmacology, pharmacokinetics, efficacy, safety, use requirements, and place in therapy of esketamine for treatment-resistant depression (TRD). Data Sources: A comprehensive PubMed search (1966 to October 2019) was conducted using the search terms depression, treatment-resistant, suicide, intranasal, esketamine, and JNJ-54135419. Additional data were obtained from references of identified articles, governmental sources, manufacturer product labeling, and Clinicaltrials.gov . Study Selection and Data Extraction: All English-language trials evaluating intranasal esketamine for TRD were included and discussed. Data Synthesis: Intranasal esketamine was approved by the US Food and Drug Administration, in conjunction with an oral antidepressant, for treating TRD in adults. Two short-term trials (TRANSFORM-1 and -2) found statistically significant reduction in the Montgomery-Asberg Depression Rating Scale score at day 28 for the fixed 56-mg dose (−4.1; 95% CI = −7.69 to −0.49; P = 0.027 [exploratory]) and flexible-dosed arms (−4.0; 95% CI = −7.31 to −0.64; P = 0.02), though the fixed-dose 84-mg arm (−3.2; 95% CI = −6.88 to 0.45; P = 0.088) of TRANSFORM-1 and TRANSFORM-3 did not (−3.6; 95% CI = −7.2 to 0.07; P = 0.059). Two long-term trials (SUSTAIN-1 and -2) suggested maintenance of response with continued use. Esketamine’s adverse effects include dizziness, dysgeusia, somnolence, dissociation, suicidal thoughts and behaviors, and increased heart rate and blood pressure. Relevance to Patient Care and Clinical Practice: Although providing a novel antidepressant mechanism and formulation for TRD, esketamine’s role in treatment will likely be limited by cost, administration, and diversion concerns. Conclusion: Intranasal esketamine significantly reduced depression symptoms in TRD, though with tolerability issues.

ObjectiveDeep brain stimulation (DBS) reduces depressive symptoms in approximately 40%–60% of patients with treatment-resistant depression (TRD), but data on long-term efficacy and safety are scarce. Our objective was to assess the efficacy and safety of DBS targeted at the ventral anterior limb of the internal capsule (vALIC) in 25 patients with TRD during a 1-year, open-label, maintenance period, which followed a 1-year optimisation period.MethodsDepression severity was measured using the 17-item Hamilton Depression Rating Scale (HAM-D-17), Montgomery-Asberg Depression Rating Scale (MADRS) and self-reported Inventory of Depressive Symptomatology (IDS-SR). Primary outcomes were response rate (≥50% HAM-D-17 score reduction) after the maintenance phase, approximately 2 years after DBS surgery, and changes in depression scores and occurrence of adverse events during the maintenance phase.ResultsOf 25 operated patients, 21 entered and 18 completed the maintenance phase. After the maintenance phase, eight patients were classified as responder (observed response rate: 44.4%; intention-to-treat: 32.0%). During the maintenance phase, HAM-D-17 and MADRS scores did not change, but the mean IDS-SR score decreased from 38.8 (95% CI 31.2 to 46.5) to 35.0 (95% CI 26.1 to 43.8) (p=0.008). Non-responders after optimisation did not improve during the maintenance phase. Four non-DBS-related serious adverse events occurred, including one suicide attempt.ConclusionsvALIC DBS for TRD showed continued efficacy 2 years after surgery, with symptoms remaining stable after optimisation as rated by clinicians and with patient ratings improving. This supports DBS as a viable treatment option for patients with TRD.Trial registration numberNTR2118.

The Impact

Abstract Background Esketamine nasal spray was recently approved for treatment-resistant depression. The current analysis evaluated the impact of symptom-based treatment frequency changes during esketamine treatment on clinical outcomes. Methods This is a post-hoc analysis of an open-label, long-term (up to 1 year) study of esketamine in patients with treatment-resistant depression (SUSTAIN 2). During a 4-week induction phase, 778 patients self-administered esketamine twice weekly plus a new oral antidepressant daily. In responders (≥50% reduction in Montgomery-Åsberg Depression Rating Scale total score from baseline), esketamine treatment frequency was thereafter decreased during an optimization/maintenance phase to weekly for 4 weeks and then adjusted to the lowest frequency (weekly or every other week) that maintained remission (Montgomery-Åsberg Depression Rating Scale ≤ 12) based on a study-defined algorithm. The relationship between treatment frequency and symptom response, based on clinically meaningful change in Clinical Global Impression–Severity score, was subsequently evaluated 4 weeks after treatment frequency adjustments in the optimization/maintenance phase. Results Among 580 responders treated with weekly esketamine for the first 4 weeks in the optimization/maintenance phase (per protocol), 26% continued to improve, 50% maintained clinical benefit, and 24% worsened. Thereafter, when treatment frequency could be reduced from weekly to every other week, 19% further improved, 49% maintained benefit, and 32% worsened. For patients no longer in remission after treatment frequency reduction, an increase (every other week to weekly) resulted in 47% improved, 43% remained unchanged, and 10% worsened. Conclusions These findings support individualization of esketamine nasal spray treatment frequency to optimize treatment response in real-world clinical practice.

Resistant Depression

IntroductionTreatment resistant depression (TRD) is a disabling condition associated with a relevant psychosocial impairment worldwide.ObjectivesThis exploratory study is aimed to evaluate the main clinical and neurocognitive characteristics in a sample of 21 subjects admitted to the Psychiatric Clinic of University of Genoa as inpatients between 2015 and 2016 and diagnosed with TRD according to Thase and Rush staging method.MethodsPatients have been assessed using the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale, and Clinical Global Impression (CGI). The Continuous Performance Test (CPT), Trial Making Test (TMT-A/B), Stroop Color Word Interference Test, Verbal Fluency Test, and Rey auditory-verbal learning test (RAVLT) have been administered as well.ResultsSubjects with early-onset (< 50 years) depression had a longer illness duration, higher depressive episodes and more impaired performance at RAVLT while individuals with late-onset (> 50 years) depression showed a higher severity of depressive symptoms and more anxiety symptoms. Depressive symptoms were positively associated with anxiety (r = 0.82; P = 0.00) and negatively with TMT-A/B (r = −0.56, P = 0.01), Stroop Color Word Interference Test (r = −0.72, P = 0.005 and r = −0.616, P = 0.008), and RAVLT (r = −0.60; P = 0.02) performances. According to regression analyses, anxiety symptoms were the only significant predictor of depression severity (P = 0.02).ConclusionsEarly-onset depression is associated with more disability and worse neurocognitive performance whereas late-onset depression is linked to more anxiety symptoms and more depressive symptoms severity. Clinicians should closely monitor patients with TRD for the presence of anxiety symptoms that may represent a significant risk factor of poorer long-term outcome.Disclosure of interestThe authors have not supplied their declaration of competing interest.
