To investigate the effectiveness, safety, and tolerability of vortioxetine in patients treated at therapeutic doses (5-20mg/day) for both acute and maintenance treatment, patient-level data were pooled from 5 long-term (52-week), open-label extension studies of major depressive disorder. The mean (±standard deviation) MADRS total score improved from 17.1±10.2 at the start of maintenance therapy to 7.6±8.2 (observed cases [OC]) or 10.3±9.9 (last observation carried forward [LOCF]) at week 52. The mean HAM-A total scores improved from 11...

Lurasidone (DS-RAn) has demonstrated efficacy in the acute treatment of bipolar depression, both as monotherapy, and as combination therapy with lithium or valproate. To evaluate the recurrence prevention efficacy of lurasidone for the maintenance treatment of bipolar I disorder, patients received up to 20 weeks of open-label lurasidone (20-80mg/d) combined with lithium or valproate during an initial stabilization phase. A total of 496 patients met stabilization criteria and were randomized to 28 weeks of double-blind treatment with lurasidone (20-80mg/d) or placebo, in combination with lithium or valproate...

The acetylcholine muscarinic M1 receptor has been implicated in both psychosis and cognition. Post-mortem research has shown reduced muscarinic M1 receptor density in 25% of chronic patients with schizophrenia. It is unknown whether reduced M1 receptor density is related to cognitive symptoms of psychosis. We investigated the role of the M1 receptor in separate cognitive domains in subjects with a psychotic disorder using a muscarinic M1 antagonist as an acute pharmacological challenge. 33 young subjects with a psychotic disorder and 30 gender, age and IQ matched healthy controls were enrolled...

We recently investigated neuromodulatory effects of the noradrenergic agent reboxetine and the dopamine receptor affine amisulpride in healthy subjects on dynamic erotic stimulus processing. Whereas amisulpride left sexual functions and neural activations unimpaired, we observed detrimental activations under reboxetine within the caudate nucleus corresponding to motivational components of sexual behavior. However, broadly impaired subjective sexual functioning under reboxetine suggested effects on further neural components...

Previous research showed that the disposition to react with disproportionate aggression in adults is influenced by an interaction between a variant in the X-chromosomal monoamine oxidase A gene (MAOA) and early traumatic events. Such studies have often focused on a single type of trauma, whereas we know that experiencing multiple trauma types is associated with more detrimental consequences. The differential susceptibility hypothesis suggests that individuals who are most susceptible to adversity, are also most likely to benefit from supportive experiences in childhood...

It is often stated that first-episode patients tend to respond better to antipsychotics than chronic patients, but the exact numbers and moderators of response in this population are unclear. We, therefore, present the first systematic review on response rates of first episode patients with schizophrenia in randomized trials. We searched multiple databases for randomized-controlled trials of antipsychotics in acutely ill patients with a first episode of schizophrenia (last search: November 17, 2016). The outcomes were response rate based on two criteria, at least 50% PANSS or BPRS total score reduction from baseline and at least 20% reduction...

Lithium (Li) and valproate (VPA) are used in the treatment of bipolar disorder (BD), with narrow therapeutic window requiring periodic control of serum levels. This prevents intoxication, lack of efficacy due to low serum concentrations, and allows monitoring adherence. We aimed at evaluating the bioequivalence of salivary and blood levels of LI or VPA in a sample of adult BD patients. Secondarily, lithium bioequivalence was evaluated across different patients' lifespans. BD patients treated with either Li or VPA underwent contemporary standard serum and salivary measurements...

Cannabis use disorder (CUD) is frequently associated with concurrent substance use and/or comorbid substance use disorders (SUDs); however there is little specificity with regard to commonly abused individual drug types/classes. This study therefore aimed to provide insight into the degree of these co-occurring relationships across several specific newer and older generation illicit and prescription drugs. 36,309 adults aged 18+ from wave 3 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were assessed...

Switching antidepressant therapy is a recommended strategy for depressed patients who neither respond to nor tolerate an initial pharmacotherapy course. This paper reviews the efficacy and tolerability of switching to vortioxetine. All three published studies of patients with major depressive disorder (MDD) switched from SSRI/SNRI therapy to vortioxetine due to lack of efficacy or tolerability were selected. Vortioxetine was evaluated versus agomelatine directly (REVIVE) and versus sertraline, venlafaxine, bupropion, and citalopram in an indirect treatment comparison (ITC) from switch studies retrieved in a literature review...

Inflammation has been linked with a potential critical role in suicide. The purpose of this study is to examine the relation of CRP with suicidal behavior in the Korean population. We conducted a cross-sectional study in 4693 Korean adults aged 20-81 years who participated in the 2015 Korea National Health and Nutrition Examination Survey. High sensitivity CRP levels were measured by immunoturbidimetric method. Suicidal ideation and suicide attempt were assessed by using a questionnaire. Data were analyzed in 2017...

Current clinical and pre-clinical data suggest that both cannabinoid agents and blockage of CRF through corticotrophin releasing factor receptor type 1 (CRFr1) may offer therapeutic benefits for post-traumatic stress disorder (PTSD). Here we aim to determine whether they are more effective when combined when microinjected into the basolateral amygdala (BLA) or CA1 area of the hippocampus after exposure to a stressful event in the shock/reminders rat model for PTSD. Injection of the fatty acid amide hydrolase (FAAH) inhibitor URB597 after the shock into either the BLA or CA1 facilitated extinction, and attenuated startle response and anxiety-like behavior...

REVIEW
Sven Ulrich, Roland Ricken, Mazda Adli
It has been over 50 years since a review has focused exclusively on the monoamine oxidase (MAO) inhibitor tranylcypromine (TCP). A new review has therefore been conducted for TCP in two parts which are written to be read preferably in close conjunction: Part I - pharmacodynamics, pharmacokinetics, drug interactions, toxicology; and Part II - clinical studies with meta-analysis of controlled studies in depression, practice of TCP treatment, place in therapy. Pharmacological data of this review part I characterize TCP as an irreversible and nonselective MAO-A/B inhibitor at low therapeutic doses of 20mg/day with supplementary norepinephrine reuptake inhibition at higher doses of 40-60mg/day...

Multiple genetic variations impact on risk for schizophrenia. Recent analyses by the Psychiatric Genomics Consortium (PGC2) identified 128 SNPs genome-wide associated with the disorder. Furthermore, attention and working memory deficits are core features of schizophrenia, are heritable and have been associated with variation in glutamatergic neurotransmission. Based on this evidence, in a sample of healthy volunteers, we used SNPs associated with schizophrenia in PGC2 to construct a Polygenic-Risk-Score (PRS) reflecting the cumulative risk for schizophrenia, along with a Polygenic-Risk-Score including only SNPs related to genes implicated in glutamatergic signaling (Glu-PRS)...

Major Depression Disorder (MDD) has a highly variable treatment response due to the large inter-individual variation in the pharmacokinetics and pharmacodynamics of drug treatments. In detail the correlation between plasma level and efficacy has been much debated. Among first-line drugs for MDD, one of the most used is escitalopram. In the present study we investigated the association between serum concentration of escitalopram (SCE) and antidepressant response (AR). 70 MDD patients treated with escitalopram monotherapy were recruited and followed for three months...

We have reported that the anticonvulsant/mood stabilizer and histone deacetylase (HDAC) inhibitor valproate (VPA) induces expression of melatonin receptors both in vitro and in vivo, but the mechanisms involved were not known. Here we show that pharmacological inhibition of CREB, PKC, PI3K, or GSK3β signaling pathways, which are known targets for VPA, do not prevent its upregulation of melatonin MT1 receptors in rat C6 glioma cells. M344, an HDAC inhibitor unrelated to VPA, mimics the effects of VPA on MT1 expression, whereas valpromide, a VPA derivative lacking HDAC inhibitory activity, does not...

Studies about reconsolidation of conditioned fear memories have shown that pharmacological manipulation at memory reactivation can attenuate or enhance the subsequent expression of the conditioned fear response. Here we examined the effects of a single injection of the mTOR inhibitor rapamycin (Rap) into the infralimbic (IL) and prelimbic (PL) areas [which compose the ventromedial prefrontal cortex (PFC)] on reconsolidation and extinction of a traumatic fear memory. We found opposite effects of Rap infused into the PL and IL on reconsolidation and extinction: intra-PL Rap and systemic Rap impaired reconsolidation and facilitated extinction whereas intra-IL Rap enhanced reconsolidation and impaired extinction...

As part of the Roamer project, we aimed at revealing the share of health research budgets dedicated to mental health, as well as on the amounts allocated to such research for four European countries. Finland, France, Spain and the United Kingdom national public and non-profit funding allocated to mental health research in 2011 were investigated using, when possible, bottom-up approaches. Specifics of the data collection varied from country to country. The total amount of public and private not for profit mental health research funding for Finland, France, Spain and the UK was €10·2, €84·8, €16·8, and €127·6 million, respectively...

Mitochondrial dysfunction may result in a variety of diseases. The objectives here were to examine possible differences in mtDNA copy number between healthy controls and patients with depression, anxiety or stress- and adjustment disorders; the association between mtDNA copy number and disease severity at baseline; and the association between mtDNA copy number and response after an 8-week treatment (mindfulness, cognitive based therapy). A total of 179 patients in primary health care (age 20-64 years) with depression, anxiety and stress- and adjustment disorders, and 320 healthy controls (aged 19-70 years) were included in the study...

Feelings of hunger carry a negative-valence (emotion) signal that appears to be conveyed through agouti-related peptide (AgRP) neurons in the hypothalamic arcuate nucleus. The circulating hunger hormone, ghrelin, activates these neurons although it remains unclear whether it also carries a negative-valence signal. Given that ghrelin also activates pathways in the midbrain that are important for reward, it remains possible that ghrelin could act as a positive reinforcer and hence, carry a positive-valence signal...

Postpartum estrogen (E2) withdrawal is known to be a particularly vulnerable time for depressive symptoms. In this study, ovariectomized (OVX) mice were treated with co-administration of estradiol benzoate and progesterone (E2/P4) followed by administration of E2 alone (E2) and a subsequent E2 withdrawal (EW) to mimic the hormonal changes during pregnancy and postpartum. The objective of this study was to investigate the influence of E2 withdrawal after hormone-simulated pregnancy on synaptic function and plasticity in basolateral amygdala complex (BLA)...
