  • A Long-Term, Open-Label Study to Evaluate the Safety and Tolerability of
           Brexpiprazole as Maintenance Treatment in Adults with Schizophrenia

    • Authors: Forbes A; Hobart M, Ouyang J, et al.
      Pages: 433 - 441
      Abstract: BackgroundBrexpiprazole is a serotonin–dopamine activity modulator with efficacy in acute schizophrenia and relapse prevention. The aim of this Phase 3, multicenter study was to assess the long-term safety, tolerability, and efficacy of treatment with brexpiprazole flexible-dose 1–4 mg/d.MethodsPatients rolled over into this 52-week open-label study (amended to 26 weeks towards the end) from 3 randomized, double-blind, placebo-controlled Phase 3 studies. De novo patients, not part of the previous studies, were also enrolled. The primary outcome variable was the frequency and severity of treatment-emergent adverse events. Efficacy was assessed as a secondary objective using the Positive and Negative Syndrome Scale and the Personal and Social Performance scale.ResultsA total of 1072 patients was enrolled (952 for 52 weeks and 120 for 26 weeks), 47.4% of whom completed the study. Among patients who took at least one dose of brexpiprazole, 14.6% discontinued due to treatment-emergent adverse events, most commonly schizophrenia (8.8%) and psychotic disorder (1.5%). Treatment-emergent adverse events with an incidence of ≥5% were schizophrenia (11.6%), insomnia (8.6%), weight increased (7.8%), headache (6.4%), and agitation (5.4%). Most treatment-emergent adverse events were mild or moderate in severity. The mean increase in body weight from baseline to week 26 was 1.3 kg and to week 52 was 2.1 kg. There were no clinically relevant findings related to prolactin, lipids, and glucose, or QT prolongation. On average, patients’ symptoms and functioning showed continual improvement.ConclusionsTreatment with brexpiprazole 1–4 mg/d was generally well tolerated for up to 52 weeks in patients with schizophrenia.ClinicalTrials.gov identifierNCT01397786 (https://clinicaltrials.gov/show/NCT01397786).

  • A Subgroup Analysis of the Impact of Vortioxetine on Functional Capacity,
           as Measured by UPSA, in Patients with Major Depressive Disorder and
           Subjective Cognitive Dysfunction

    • Authors: Keefe R; Nomikos G, Zhong W, et al.
      Pages: 442 - 447
      Abstract: BackgroundWe evaluated vortioxetine’s effects on functional capacity in demographic and clinical subgroups of patients with major depressive disorder.MethodsThis was an exploratory analysis of the CONNECT study (NCT01564862) that evaluated changes in functional capacity using University of California San Diego Performance-based Skills Assessment data, categorized by sex, age, education, employment status, and baseline disease severity (Montgomery-Åsberg Depression Rating Scale, Clinical Global Impressions–Severity of Illness).ResultsGreater changes in University of California San Diego Performance-based Skills Assessment composite scores were observed with vortioxetine vs placebo in specific subgroups: males (∆+3.2), females (∆+2.9), 45–54 or ≥55 years (∆+5.6, ∆+3.4), working (∆+2.8), high school or greater education (∆+2.7, ∆+2.8), disease severity (Montgomery-Åsberg Depression Rating Scale, <30, ∆+3.5; ≥30, ∆+2.5; Clinical Global Impressions–Severity of Illness ≤4, ∆+2.8; >4, ∆+3.0), major depressive episodes (≤2, >2 [∆+2.7,+3.3]), and episode duration (≤22, >22 weeks [∆+3.7,+2.4]).ConclusionsOur findings support the need for additional studies to assess whether vortioxetine improves functional capacity within specific patient subgroups.Clinical Trial Registryclinicaltrials.gov: NCT01564862

  • The Dopamine Receptor D3 Regulates Lipopolysaccharide-Induced
           Depressive-Like Behavior in Mice

    • Authors: Wang J; Jia Y, Li G, et al.

      Abstract: BackgroundThe altered expression and function of dopamine receptor D3 (D3R) in patients and animal models have been correlated with depression disease severity. However, the morphological alterations and biological effects of D3R in the brain after inflammation-induced depressive-like behavior remain elusive.MethodsIn the present study, we ascertained the changes of D3R expression in the brain regions after depressive-like behavior induced by peripheral administration of lipopolysaccharide (LPS). Protein levels of proinflammatory cytokines, brain-derived neurotrophic factor (BDNF), and extracellular signal-regulated kinase (ERK1/2)-cAMP-response element-binding protein (CREB) signaling pathway after activation or inhibition of D3R in the brain of depressive mice were also investigated.ResultsLPS caused a significant reduction of D3R in the ventral tegmental area (VTA), medial prefrontal cortex (mPFC), and nucleus accumbens (NAc), which are areas related to the mesolimbic dopaminergic system. Pretreatment with pramipexole (PPX), a preferential D3R agonist, showed antidepressant effects on LPS-induced depression-like behavior through preventing changes in LPS-induced proinflammatory cytokines (tumour necrosis factor-α, interleukin-1β, and interleukin-6), BDNF, and ERK1/2-CREB signaling pathway in the VTA and NAc. In opposition, treatment with a D3R selective antagonist NGB 2904 alone made mice susceptible to depression-like effects and caused changes in accordance with the LPS-induced alterations in proinflammatory cytokines, BDNF, and the ERK1/2-CREB signaling pathway in the mPFC and NAc.ConclusionsThese findings provide a relevant mechanism for D3R in LPS-induced depressive-like behavior via its mediation of proinflammatory cytokines and potential cross-effects between BDNF and the ERK1/2-CREB signaling pathway.

  • Long Noncoding RNA-Associated Transcriptomic Changes in Resiliency or
           Susceptibility to Depression and Response to Antidepressant Treatment

      Abstract: BackgroundRecent emergence of long noncoding RNAs in regulating gene expression and thereby modulating physiological functions in brain has manifested their possible role in psychiatric disorders. In this study, the roles of long noncoding RNAs in susceptibility and resiliency to develop stress-induced depression and their response to antidepressant treatment were examined.MethodsMicroarray-based transcriptome-wide changes in long noncoding RNAs were determined in hippocampus of male Holtzman rats who showed susceptibility (learned helplessness) or resiliency (nonlearned helplessness) to develop depression. Changes in long noncoding RNA expression were also ascertained after subchronic administration of fluoxetine to learned helplessness rats. Bioinformatic and target prediction analyses (cis- and trans-acting) and qPCR-based assays were performed to decipher the functional role of altered long noncoding RNAs.ResultsGroup-wise comparison showed an overrepresented class of long noncoding RNAs that were uniquely associated with nonlearned helplessness or learned helplessness behavior. Chromosomal mapping within the 5-kbp flank region of the top 20 dysregulated long noncoding RNAs in the learned helplessness group showed several target genes that were regulated through cis- or trans-actions, including Zbtb20 and Zfp385b from zinc finger binding protein family. Genomic context of differentially expressed long noncoding RNAs showed an overall blunted response in the learned helplessness group regardless of the long noncoding RNA classes analyzed. Gene ontology exhibited the functional clustering for anatomical structure development, cellular architecture modulation, protein metabolism, and cellular communications. Fluoxetine treatment reversed learned helplessness-induced changes in many long noncoding RNAs and target genes.ConclusionsThe involvement of specific classes of long noncoding RNAs with distinctive roles in modulating target gene expression could confer the role of long noncoding RNAs in resiliency or susceptibility to develop depression with a reciprocal response to antidepressant treatment.

  • A Preclinical Study of Casein Glycomacropeptide as a Dietary Intervention
           for Acute Mania

    • Authors: Liebenberg N; Jensen E, Larsen E, et al.
      Pages: 473 - 484
      Abstract: BackgroundCasein glycomacropeptide is a peptide that lacks phenylalanine, tyrosine, and tryptophan. This profile may enable it to deplete phenylalanine, tyrosine, and tryptophan, and subsequently the synthesis of dopamine and serotonin in the brain. Dopamine- and serotonin-depleting amino acid mixtures have shown promise as acute antimanic treatments. In this study, we explore the depleting effects on amino acids, dopamine and serotonin as well as its actions on manic-like and other behavior in rats.MethodsCasein glycomacropeptide and a selection of amino acid mixtures were administered orally at 2, 4, or 8 h or for 1 week chronically. Amino acid and monoamine levels were measured in plasma and brain and behavior was assessed in the amphetamine-hyperlocomotion, forced swim, prepulse inhibition, and elevated plus maze tests.ResultsCasein glycomacropeptide induced a time-dependent reduction in tyrosine, tryptophan, and phenylalanine in brain and plasma which was augmented by supplementing with leucine. Casein glycomacropeptide +leucine reduced dopamine in the frontal cortex and serotonin in the hippocampus, frontal cortex, and striatum after 2 and 4 h. Casein glycomacropeptide+leucine also had antimanic activity in the amphetamine-induced hyperlocomotion test at 2 h after a single acute treatment and after 1 week of chronic treatment.ConclusionsCasein glycomacropeptide-based treatments and a branched-chain amino acid mixture affected total tissue levels of dopamine in the frontal cortex and striatum and serotonin in the frontal cortex, striatum, and hippocampus of rats in a time-dependent fashion and displayed antimanic efficacy in a behavioral assay of mania.

  • Cerebellar BDNF Promotes Exploration and Seeking for Novelty

    • Authors: Laricchiuta D; Andolina D, Angelucci F, et al.
      Pages: 485 - 498
      Abstract: BackgroundApproach system considered a motivational system that activates reward-seeking behavior is associated with exploration/impulsivity, whereas avoidance system considered an attentional system that promotes inhibition of appetitive responses is associated with active overt withdrawal. Approach and avoidance dispositions are modulated by distinct neurochemical profiles and synaptic patterns. However, the precise working of neurons and trafficking of molecules in the brain activity predisposing to approach and avoidance are yet unclear.MethodsIn 3 phenotypes of inbred mice, avoiding, balancing, and approaching mice, selected by using the Approach/Avoidance Y-maze, we analyzed endogenous brain levels of brain derived neurotrophic factor, one of the main secretory proteins with pleiotropic action. To verify the effects of the acute increase of brain derived neurotrophic factor, balancing and avoiding mice were bilaterally brain derived neurotrophic factor-infused in the cortical cerebellar regions.ResultsApproaching animals showed high levels of explorative behavior and response to novelty and exhibited higher brain derived neurotrophic factor levels in the cerebellar structures in comparison to the other 2 phenotypes of mice. Interestingly, brain derived neurotrophic factor-infused balancing and avoiding mice significantly increased their explorative behavior and response to novelty.ConclusionsCerebellar brain derived neurotrophic factor may play a role in explorative and novelty-seeking responses that sustain the approach predisposition.

  • Copy Number Variant in the Region of Adenosine Kinase (ADK) and Its
           Possible Contribution to Schizophrenia Susceptibility

    • Authors: Kimura H; Kushima I, Yohimi A, et al.
      Pages: 405 - 409
      Abstract: BackgroundAdenosine kinase (ADK) is supposed to be a schizophrenia susceptibility gene based on the findings that ADK is an enzyme that catalyzes transfer of the gamma-phosphate from ATP to adenosine, which interacts with dopamine and glutamate neurotransmitters. However, no reports of schizophrenia cases with loss of function variants in the ADK region have been published. In our previous study investigating copy number variants in schizophrenia, we detected a copy number variant in the ADK region in 1 of 1699 schizophrenia patients.MethodsWe validated the ADK deletion by determining the breakpoint. Then, we compared the relative expression of ADK in 32 schizophrenia patients, including a schizophrenia patient with deletion of ADK, with 29 healthy controls using lymphoblastoid cell lines. Furthermore, we evaluated the clinical phenotypes of the schizophrenia with ADK deletion.ResultWe validated the copy number variants with Sanger sequencing and predicted that this copy number variant results in loss of function of ADK. Furthermore, expression analysis of mRNA from peripheral blood in this schizophrenia patient with the ADK deletion showed an extremely low level of ADK. Here we describe a case report of a patient with ADK deletion with phenotypes (schizophrenia, parkinsonism, epilepsy) that are predicted when ADK function is disrupted.ConclusionConsidering that the patient had a low ADK mRNA level and showed a phenotype that may be related to ADK deficiency, the copy number variants in the region of ADK may be strongly related to the phenotypes described here, such as schizophrenia, Parkinsonism, and epilepsy.

  • Cardiovascular Risk in Early Psychosis: Relationship with Inflammation and
           Clinical Features 6 Months after Diagnosis

    • Authors: Barcones M; MacDowell K, García-Bueno B, et al.
      Pages: 410 - 422
      Abstract: BackgroundWe aimed to investigate the state of cardiovascular risk/protection factors in early psychosis patients.MethodsA total 119 subjects were recruited during the first year after their first episode of psychosis. Eighty-five of these subjects were followed during the next 6 months. Cardiovascular risk/protection factors were measured in plasma and co-variated by sociodemographic/clinical characteristics. Multiple linear regression models detected the change of each biological marker from baseline to follow-up in relation to clinical scales, antipsychotic medication, and pro-/antiinflammatory mediators.ResultsGlycosylated hemoglobin is a state biomarker in first episode of psychosis follow-up patients and inversely correlated to the Global Assessment of Functioning scale. We found opposite alterations in the levels of VCAM-1 and E-selectin in first episode of psychosis baseline conditions compared with control that were absent in the first episode of psychosis follow-up group. Adiponectin levels decreased in a continuum in both pathological time points studied. E-Selectin plasma levels were inversely related to total antipsychotic equivalents and adiponectin levels inversely co-related to the Global Assessment of Functioning scale. Finally, adiponectin levels were directly related to antiinflammatory nuclear receptor PPARγ expression in first episode of psychosis baseline conditions and to proinflammatory nuclear factor nuclear factor κB activity in follow-up conditions, respectively.ConclusionsOur results support the need for integrating cardiovascular healthcare very early after the first episode of psychosis.

  • Monoamine Oxidase A Gene Methylation and Its Role in Posttraumatic Stress
           Disorder: First Evidence from the South Eastern Europe (SEE)-PTSD Study

    • Authors: Ziegler C; Wolf C, Schiele M, et al.
      Pages: 423 - 432
      Abstract: BackgroundPosttraumatic stress disorder is characterized by an overactive noradrenergic system conferring core posttraumatic stress disorder symptoms such as hyperarousal and reexperiencing. Monoamine oxidase A is one of the key enzymes mediating the turnover of noradrenaline. Here, DNA methylation of the monoamine oxidase A gene exonI/intronI region was investigated for the first time regarding its role in posttraumatic stress disorder risk and severity.MethodsMonoamine oxidase A methylation was analyzed via direct sequencing of sodium bisulfite-treated DNA extracted from blood cells in a total sample of N=652 (441 male) patients with current posttraumatic stress disorder, patients with remitted posttraumatic stress disorder, and healthy probands (comparison group) recruited at 5 centers in Bosnia-Herzegovina, Croatia, and the Republic of Kosovo. Posttraumatic stress disorder severity was measured by means of the Clinician-Administered Posttraumatic Stress Disorder Scale and its respective subscores representing distinct symptom clusters.ResultsIn the male, but not the female sample, patients with current posttraumatic stress disorder displayed hypermethylation of 3 CpGs (CpG3=43656362; CpG12=43656514; CpG13=43656553, GRCh38.p2 Assembly) as compared with remitted Posttraumatic Stress Disorder patients and healthy probands. Symptom severity (Clinician-Administered Posttraumatic Stress Disorder Scale scores) in male patients with current posttraumatic stress disorder significantly correlated with monoamine oxidase A methylation. This applied particularly to symptom clusters related to reexperiencing of trauma (cluster B) and hyperarousal (cluster D).ConclusionsThe present findings suggest monoamine oxidase A gene hypermethylation, potentially resulting in enhanced noradrenergic signalling, as a disease status and severity marker of current posttraumatic stress disorder in males. If replicated, monoamine oxidase A hypermethylation might serve as a surrogate marker of a hyperadrenergic subtype of posttraumatic stress disorder guiding personalized treatment decisions on the use of antiadrenergic agents.
