Depression is often misdiagnosed as major depressive disorder in patients with bipolar disorder. Therapeutic drugs for these two disorders are quite different, but the anesthetic ketamine shows fast-acting antidepressant effects in treatment-resistant patients with these disorders. Here, we discuss biomarkers for both disorders, recent findings regarding ketamine, and predictable biomarkers for ketamine's antidepressant actions.

The depressive state has been characterised as one of elevated inflammation, changed cardiovascular parameters and a deranged metabolic situation all of which holds promise for a better understanding and handling of treatment-resistance in affective disorders as well as for future developments in treatment algorithms. In this context several biomarkers are differentially regulated by antidepressant treatment and connected to metabolic, inflammatory, cardiovascular and apoptotic components of the pathophysiology, i...

Background: Diagnostic biomarkers of major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SZ) are urgently needed because none are currently available. Methods: We performed a comprehensive metabolome analysis of plasma samples from drug-free patients with MDD (n = 9), BD (n = 6), SZ (n = 17), and matched healthy controls (n = 19) (cohort 1), using liquid chromatography time-of-flight mass spectrometry. A significant effect of diagnosis was found for two metabolites: nervonic acid and cortisone, with nervonic acid being the most significantly altered...

BACKGROUND: This study sought to reproduce, in a larger sample, previous findings of a correlation between smaller raw 3-Tesla (3T) hippocampal volumes and improved antidepressant efficacy of ketamine in individuals with major depressive disorder (MDD). A secondary analysis stratified subjects according to functional BDNF rs6265 (val66met) genotype. METHODS: Unmedicated subjects with treatment-resistant MDD ( n=55) underwent baseline structural 3T MRI. Data processing was conducted with FSL/FIRST and Freesurfer software...

BACKGROUND: Prefrontal global brain connectivity with global signal regression (GBCr) was proposed as a robust biomarker of depression, and was associated with ketamine's mechanism of action. Here, we investigated prefrontal GBCr in treatment-resistant depression (TRD) at baseline and following treatment. Then, we conducted a set of pharmacological challenges in healthy subjects to investigate the glutamate neurotransmission correlates of GBCr. METHODS: In study A, we used functional magnetic resonance imaging (fMRI) to compare GBCr between 22 TRD and 29 healthy control...

OBJECTIVES: Antidepressant treatment alters brain-derived neurotrophic factor (BDNF) levels, but it is not well established whether BDNF can be used as a marker to prove the efficacy of antidepressant treatment. The present systematic review and meta-analysis aim at assessing the influence of antidepressant treatment on BDNF level and the Hamilton Depression Rating Scale (HDRS) score, thereby to establish the rationale of utilizing BDNF as a predictive biomarker and HDRS score as an indicator for antidepressant treatment efficacy...

BACKGROUND: The pattern of serotonin transporter clustering on the plasma membrane of lymphocytes extracted from human whole blood samples has been identified as a putative biomarker of therapeutic efficacy in major depression. Here we evaluated the possibility of performing a similar analysis using blood smears obtained from rats, and from control human subjects and depression patients. We hypothesized that we could optimize a protocol to make the analysis of serotonin protein clustering in blood smears comparable to the analysis of serotonin protein clustering using isolated lymphocytes...

Background: Platelet derived growth factor is integral to maintenance of blood brain barrier, increases in response to blood brain barrier disruption, and may reflect neuroinflammation. Based on previous reports of better outcomes with dopaminergic antidepressants in depressed patients with elevated inflammatory biomarkers, we hypothesize that elevated peripheral platelet derived growth factor levels can serve as a powerful biomarker for selecting dopaminergic antidepressants. Methods: Platelet derived growth factor, basic fibroblast growth factor, and granulocyte colony stimulating factor were measured as part of Bioplex Pro human cytokine 27-plex kit in participants of the Combining Medications to Enhance Depression Outcomes trial who provided baseline plasma (n=166) and were treated with either bupropion-plus-escitalopram, escitalopram-plus-placebo, or venlafaxine-plus-mirtazapine...

Research suggests that exposure therapy provided in the hours immediately following trauma exposure may prevent PTSD development. This case report presents data on an at-risk for PTSD participant involved in a motor-vehicle crash that caused her severe distress. She received one session of exposure therapy in the emergency department (ED) as part of an ongoing randomized controlled study examining the optimal dose of exposure therapy in the immediate aftermath of trauma. PTSD and depression measures were collected at pre-treatment assessment and one- and three-month follow-up...

In recent years, vascular depression has become the focus of international attention. Yangxinshi Tablet (YXST) is usually used in clinic for treatment of arrhythmia and heart failure, but we found that it also has anti-depressive effect in this study. The objective of the study was to identify biomarkers related to vascular depression in hippocampus and explore the anti-depressive effects of YXST on the mice model. Untargeted metabolomics based on UHPLC-Q-TOF/MS was applied to identify significant differential biomarkers between model group and control group...

The search for biomarkers has been a leading endeavor in biological psychiatry. To analyze its evolution over the years, we performed a systematic review to evaluate (a) the most studied peripheral molecular markers in major psychiatric disorders, (b) the main features of studies proposing them as biomarkers and (c) whether their patterns of variation are similar across disorders. Of the six molecules most commonly studied as plasmatic markers of schizophrenia, major depressive disorder or bipolar disorder, five (BDNF, TNF-alpha, IL-6, C-reactive protein and cortisol) were the same across diagnoses...

BACKGROUND: Cancer patients experience pain that has physiological, sensory, affective, cognitive, behavioral, and sociocultural dimensions. Opioids are used in treatment of pain in patients with various types of cancer. We previously showed that the catechol-O-methyltransferase (COMT) genotype is related to the plasma level of morphine and the required dose of morphine in an exploratory prospective study. The findings showed that a group of patients with a GG single nucleotide polymorphism (SNP) rs4680 in COMT required a significantly higher dose of morphine than a non-GG group...

Understanding pathways of risk following a natural disaster may help create next-generation targeted interventions. The current study examined if a biomarker of cognitive-affective response (pupil dilation) could identify which individuals are at greatest risk for depression following disaster-related stress. Fifty-one women completed a computer-based task assessing pupillary response to facial expressions of emotion and reported their depressive symptoms before the 2011 Binghamton flood. Following the flood, women were assessed for objective levels of flood-related stress and again reported their depressive symptoms...

Major depression is a psychiatric disorder with high prevalence in the general population, with increasing expression in adolescence, about 14% in young people. Frequently, it presents as a chronic condition, showing no remission even after several pharmacological treatments and persisting in adult life. Therefore, distinct protocols and animal models have been developed to increase the understanding of this disease or search for new therapies. To this end, this study investigated the effects of chronic social isolation and the potential antidepressant action of nortriptyline in juvenile Callithrix jacchus males and females by monitoring fecal cortisol, body weight, and behavioral parameters and searching for biomarkers and a protocol for inducing depression...

BACKGROUND: Acute ischemic stroke (AIS) represents an economic challenge for health systems all over the globe. Changes of neuroactive steroids have been found in different neurological diseases. We have previously demonstrated that old patients with AIS show changes of plasma cortisol and estradiol concentrations, in that increased steroid levels are associated with a deterioration of neurological status and a worse cognitive decline. OBJECTIVE: The present study assessed in patients with AIS if changes of behavior, brain-derived neurotrophic factor (BDNF) and nitrites (NO-2) bear a relationship with the degree of hypercortisolism...

BACKGROUND: Pharmacological treatment of depression is currently led by the trial and error principle mainly because of lack of reliable biomarkers. Earlier findings suggest that baseline alpha power and asymmetry could differentiate between responders and non-responders to specific antidepressants. AIM: The current study investigated quantitative electroencephalographic (QEEG) measures before and early in treatment as potential response predictors to various antidepressants in a naturalistic sample of depressed patients...

BACKGROUND: Frontal EEG asymmetry is a widely studied correlate of emotion processing and psychopathology. Recent research suggests that frontal EEG asymmetry during resting state is related to approach/withdrawal motivation and is also found in affective disorders such as major depressive disorder. Patients with borderline personality disorder (BPD) show aberrant behavior in relation to both approach and withdrawal motivation, which may arguably be associated with their difficulties in emotion processing...

The prevalence of the fragile X premutation (55-200 CGG repeats) among the general population is relatively high, but there remains a lack of clear understanding of the links between molecular biomarkers and clinical outcomes. In this study we investigated the correlations between molecular measures (CGG repeat size, FMR1 mRNA, FMRP expression levels, and methylation status at the promoter region and in FREE2 site) and clinical phenotypes (anxiety, obsessive compulsive symptoms, depression and executive function deficits) in 36 adult premutation female carriers and compared to 24 normal control subjects...
