BACKGROUND: Functional neuroimaging studies have examined the neural substrates of treatments for major depressive disorder (MDD). Low sample size and methodological heterogeneity, however, undermine the generalizability of findings from individual studies. We conducted a meta-analysis to identify reliable neural changes resulting from different modes of treatment for MDD and compared them with each other and with reliable neural functional abnormalities observed in depressed versus control samples...

Studies reported a strong genetic correlation between the Big Five personality traits and major depressive disorder (MDD). Moreover, personality traits are thought to be associated with response to antidepressants treatment that might partly be mediated by genetic factors. In this study, we examined whether polygenic scores (PGSs) derived from the Big Five personality traits predict treatment response and remission in patients with MDD who were prescribed selective serotonin reuptake inhibitors (SSRIs). In addition, we performed meta-analyses of genome-wide association studies (GWASs) on these traits to identify genetic variants underpinning the cross-trait polygenic association...

BACKGROUND: Emerging genetic, ex-vivo, and clinical trial evidence indicates that calcium channel blockers (CCB) can improve mood and cognitive function. The objective of this study was to examine the effect of selective serotonin reuptake inhibitor (SSRI) therapy augmented with CCB on depression and cognitive decline in an elderly population with hypertension. METHODS: Prospective study of 296 persons treated with SSRI and antihypertensive drugs. Baseline and two year clinic assessments were used to categorize participants as users of SSRI + CCB (n = 53) or users of SSRI + other antihypertensives (n = 243)...

Immune system activation and neuroinflammation appear to play a key role in the pathophysiology and treatment of bipolar depression (BDD). This study is the first to analyze blood levels of the pro-inflammatory biomarker C-reactive protein (CRP) in bipolar disorder patients treated with the cyclooxygenase-2 inhibitor, celecoxib (CBX). In this double-blind study, 47 consenting patients with BDD were randomized to receive either escitalopram (10 mg twice/day) + CBX (200 mg twice/day), or escitalopram (10 mg twice/day) + placebo (twice/day)...

This study aimed to evaluate if efficacy and tolerability of switching to vortioxetine is independent of previous SSRI or SNRI treatment in patients who had been inadequately treated for their current major depressive episode. Patients from a double-blind, 12-week comparator study were randomized (1:1) to vortioxetine (10-20 mg/day) or agomelatine (25-50 mg/day). The pre-defined primary efficacy endpoint was change from baseline to week 8 in MADRS total score analyzed by MMRM. An ANCOVA-LOCF was conducted as a sensitivity analysis...

Depression is a kind of mental illness accompanied by complex etiology and pathogenesis in clinic. With the quickening pace of circadian rhythm and increase of life pressure in modern society, the incidence of depression is increasing year by year. Nowadays, some typical antidepressant Western medicines, such as selective serotonin re-uptake inhibitors (SSRI) and tricyclic antidepressants (TCA), have been used as the main therapeutic drugs in clinic. Unfortunately, administration of these drugs will result in severe adverse reactions, slow treatments, and low cure rates, thus obviously they can not be used for a long term...

INTRODUCTION: Adverse effects with bleeding disorders are often associated with the administration of SSRI in depression, although the exact mechanisms remain contradicting. This study is aimed at detecting and exploring the mechanisms of SSRI-induced changes in platelet reactivity in non-responding patients with Recurrent Depressive Disorder (RDD) and life-long exposure to antidepressants. MATERIALS AND METHODS: Thirty-one patients and thirty-one healthy controls were included in the study...

It is well-known that the exposure of rodents to threatening environments [e.g., the open arm of the elevated-plus maze (EPM)] elicits pain inhibition. Systemic and/or intracerebral [e.g., periaqueductal gray matter, amygdala) injections of antiaversive drugs [e.g., serotonin (5-HT) ligands, selective serotonin reuptake inhibitors (SSRIs)] have been used to change EPM-open arm confinement induced antinociception (OAA). Here, we investigated (i) the role of the 5-HT1A and 5-HT2C receptors located in the amygdaloid complex on OAA as well as (ii) the effects of systemic pretreatment with fluoxetine (an SSRI) on the effects of intra-amygdala injections of 8-OH-DPAT (a 5-HT1A agonist) or MK-212 (a 5-HT2C agonist) on nociception in mice confined to the open arm or enclosed arm of the EPM...

Selective serotonin reuptake inhibitors (SSRIs) are the most effective and most used antidepressant drugs. Acting by inhibiting serotonin (5-HT) transporter, SSRIs display a typical 3-4-week delay in their therapeutic effects, with nearly 40% of depressed patients remaining treatment-resistant. Recent evidence suggests complex interplay between 5-HT receptors and key proteins of 5-HT metabolism in molecular mechanisms of such delay and resistance to SSRIs. Area covered: This paper concentrates on the interplay between 5-HT receptors in the delay of therapeutic effect of SSRIs, and the interaction between tryptophan hydroxylase 2 and 5-HT transporter in the SSRI resistance...

BACKGROUND: Research suggests that individuals with anxiety have difficulty ignoring threat distractors when completing tasks with competing stimuli. Studies examining the neural correlates of these emotional processing difficulties in youth anxiety highlight reduced recruitment of regions associated with goal-directed attention, such as the anterior cingulate cortex (ACC). In the current study, we examined neural activation during an emotional conflict task in youth with anxiety disorders before and after treatment...

In the second part we focus on two treatment strategies that may overcome the main limitations of current antidepressant drugs. First, we review the experimental and clinical evidence supporting the use of glutamatergic drugs as fast-acting antidepressants. Secondly, we review the involvement of microRNAs (miRNAs) in the pathophysiology of major depressive disorder (MDD) and the use of small RNAs (e.g.., small interfering RNAs or siRNAs) to knockdown genes in monoaminergic and non-monoaminergic neurons and induce antidepressant-like responses in experimental animals...

BACKGROUND AND OBJECTIVES: prescription rates of antidepressants during pregnancy range from 2-3% in The Netherlands to 6.2% in the USA. Inconclusive evidence about harms and benefits of antidepressants during pregnancy leads to variation in advice given by gynaecologists and midwives. The objective was to investigate familiarity with, and adherence to the Dutch multidisciplinary guideline on Selective Serotonin Reuptake Inhibitor (SSRI) use during pregnancy by gynaecologists and midwives in the Netherlands...

BACKGROUND: Currently, there are no valid clinical or biological markers to personalize the treatment of depression. Recent evidence suggests that body mass index (BMI) may guide the selection of antidepressant medications with different mechanisms of action. METHODS: Combining Medications to Enhance Depression Outcomes (CO-MED) trial participants with BMI measurement (n = 662) were categorized as normal- or underweight (<25), overweight (25-<30), obese I (30-<35), and obese II+ (≥35)...

The success of osseointegration is influenced by several factors that affect bone metabolism and by certain systemic medications. Selective serotonin reuptake inhibitors have been previously suggested to be among these medications. This study aims to investigate the association between systemic intake of SSRIs and failure of osseointegration in patients rehabilitated with dental implants. A retrospective cohort study was conducted including a total of 2055 osseointegrated dental implants in 631 patients (109 implants in 36 SSRI-users and 1946 in 595 non-users)...

5-Hydroxytryptamine (5-HT) and noradrenaline have been thought to play important roles in the mechanism of hot flush. Then, to clarify the relation between serotonergic and adrenergic nervous systems on the mechanism of hot flush, the effect of paroxetine, 5-HT reuptake inhibitor (SSRI) was evaluated on the yohimbine-induced hot flush increase of tail skin temperature in ovariectomized female rats. Yohimbine (adrenaline α2 antagonist) significantly increased the tail skin temperature in course of time. Clonidine (adrenaline α2 agonist) significantly attenuated this effect...

This study reports follow-up 2 and 3 years after the initial assessment of a sample of youth with a primary diagnosis of OCD. Participants were 109 children and adolescents, aged 5-17 years, recruited from a specialized, outpatient OCD clinic in Sweden. Patients were treated with cognitive behavioral therapy (CBT), augmented when indicated by selective serotonin reuptake inhibitor (SSRI). In cases where SSRIs were insufficient, augmentation with a second-generation antipsychotic (SGA) was applied. Participants were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), Children's OCD Impact Scale (COIS), and Children's Depressive Inventory (CDI) at follow-ups 2 and 3 years after baseline assessment...
