Real-world effectiveness trials suggest that antidepressant efficacy is limited in many patients with mood disorders, underscoring the urgent need for novel therapeutics to treat these disorders. Areas Covered: Here, we review the clinical evidence supporting the use of novel modulators for the treatment of mood disorders, including specific glutamate modulators such as: 1) high-trapping glutamatergic modulators; 2) subunit (NR2B)-specific N-methyl-D-aspartate (NMDA) receptor antagonists; 3) NMDA receptor glycine-site partial agonists; and 4) metabotropic glutamate receptor (mGluR) modulators...

OBJECTIVE: The malnutrition-inflammation score (MIS) combines ten components to assess nutritional status. Higher MIS has been associated with higher mortality and poorer health-related quality of life (HRQOL) in maintenance hemodialysis (MHD) patients. It is interesting to investigate associations of each component with mortality and patient-reported outcomes (PROs), that is, HRQOL and depression symptoms, and if MIS associations are generalizable for diverse populations. This study assessed associations of MIS and its components with mortality and PROs in an African descent MHD population...

An accumulating body of evidence has demonstrated that inflammation is associated with the pathology of depression. We recently found that psychological stress induces inflammation in the hippocampus of the rat brain through the inflammasome, a component of the innate immune system. Microglia, the resident macrophages in the brain, play a central role in the innate immune system and express inflammasomes; thus, we hypothesized that hippocampal microglia would be key mediators in the development of depression via stress-induced inflammation...

INTRODUCTION: Single-disorder or single-organ-system clinical practice guidelines are often of limited usefulness in guiding effective management of patients with chronic multidimensional signs and symptoms. The presence of multiple long-standing medical problems in a given patient despite intensive medical effort suggests that addressing systemic core imbalances could complement more narrowly focused approaches. CASE PRESENTATION: A 72-year-old man experiencing longstanding depression, fatigue, irritable bowel syndrome, and chronic pain in the context of additional refractory illnesses was assessed and treated, guided by a system-oriented approach to underlying core imbalances termed functional medicine...

Stress is associated with many diseases and dysfunctions, such as depression, cardiovascular alterations, immunological function disorder, inflammation, obesity, and insulin resistance. Stress-induced inflammation is associated with the genesis of insulin resistance. Stress activates hypothalamic pituitary adrenal axis, Renin Angiotensin System pathway, and sympatho-adrenal system, all of which are involved in the production of cytokines, causing the negative downregulation of insulin signaling either by phosphorylating serine residues of IRS or by inhibiting the activity of Akt leading to insulin resistance...

The kynurenine pathway of tryptophan metabolism has an important role in mediating the behavioral effects of inflammation, which has implications in understanding neuropsychiatric comorbidity and for the development of novel therapies. Inhibition of the rate-limiting enzyme, indoleamine 2,3-dioxygenase (IDO), prevents the development of many of these inflammation-induced preclinical behaviors. However, dysregulation in the balance of downstream metabolism, where neuroactive kynurenines are generated, is hypothesized to be a functionally important pathogenic feature of inflammation-induced depression...

Inflammatory cytokines are commonly elevated in acute depression and are associated with resistance to monoaminergic treatment. To examine the potential role of cytokines in the pathogenesis and treatment of depression, we carried out a systematic review and meta-analysis of antidepressant activity of anti-cytokine treatment using clinical trials of chronic inflammatory conditions where depressive symptoms were measured as a secondary outcome. Systematic search of the PubMed, EMBASE, PsycINFO and Cochrane databases, search of reference lists and conference abstracts, followed by study selection process yielded 20 clinical trials...

OBJECTIVE: Psychological constructs are associated with cardiovascular health, but the biological mechanisms mediating these relationships are unknown. We examined relationships between psychological constructs and markers of inflammation, endothelial function, and myocardial strain in a cohort of post-acute coronary syndrome (ACS) patients. METHODS: Participants (N = 164) attended study visits 2 weeks and 6 months after ACS. During these visits, they completed self-report measures of depressive symptoms, anxiety, optimism, and gratitude; and blood samples were collected for measurement of biomarkers reflecting inflammation, endothelial function, and myocardial strain...

A 70-year-old woman presented with follicular lymphoma involving the stomach, duodenum, jejunum, bone, and lymph nodes. Esophagogastroduodenoscopy revealed multiple depressed lesions in the stomach. Examination with magnifying endoscopy showed branched abnormal vessels along with gastric pits, which were irregularly shaped but were preserved. The second case was a 45-year-old man diagnosed with stage II1 follicular lymphoma with duodenal, ileal, and colorectal involvement, as well as lymphadenopathy of the mesenteric lymph nodes...

Opioids are effective at inhibiting responses to noxious stimuli in rodents, but have limited efficacy and many side effects in chronic pain patients. One reason for this disconnect is that nociception is typically assessed using withdrawal from noxious stimuli in animals, whereas chronic pain patients suffer from abnormal pain that disrupts normal activity. We hypothesized that assessment of home cage wheel running in rats would provide a much more clinically relevant method to assess opioid efficacy to restore normal behavior...

BACKGROUND: high-sensitivity C-reactive protein (CRP) has been associated with cardiovascular events and mortality, but the association of CRP with functional status is not well defined. We hypothesised that serum levels of high-sensitivity CRP are associated with long-term trajectories of functional status independently of vascular risk factors and stroke and myocardial infarction (MI) occurring during follow-up. DESIGN: prospective, population-based. SETTING: northern Manhattan Study...

There is a growing appreciation that the complications of obesity extend to the central nervous system (CNS) and include increased risk for development of neuropsychiatric co-morbidities such as depressive illness. The neurological consequences of obesity may develop as a continuum and involve a progression of pathological features which is initiated by leptin resistance. Leptin resistance is a hallmark feature of obesity, but it is unknown whether leptin resistance or blockage of leptin action is casually linked to the neurological changes which underlie depressive-like phenotypes...

Exposure to painful procedures and/or stressors during the early neonatal period can reprogram the underlying neurocircuitry involved in nociception and neuropathic pain perception. The reprogramming of these systems can result in an enduring elevation in sensitivity towards mechanical and thermal stimuli. Recent evidence suggests that exposure to mild inflammatory mediators during the neonatal period can induce similar pain responses in both adolescent and adult rats. Therefore, we sought to profile changes in the expression of several genes across brain areas involved in the active modulation of nociception and neuropathic pain using a well-recognized model of neonatal inflammation...

Studies have shown that the presence of acute inflammation during recovery is indicative of poor outcomes after a traumatic brain injury (TBI); however, the role of chronic inflammation in predicting post-TBI related symptoms remains poorly understood. The purpose of this study was to compare inflammatory biomarkers (TNF-α, IL-6 and IL-10) in active duty personnel who either sustained or did not sustain a TBI. Service members were also assessed for post-traumatic stress disorder (PTSD), depression, and quality-of-life (QOL) through self-reported measures...

Emotional impairments such as depressive symptoms often develop in patients with sustained and systemic immune activation. The objective of this study is to investigate the effect of gomisin N, a dibenzocyclooctadiene lignan isolated from the dried fruits of Schisandra chinensis (Turcz.) Baill., which exhibited inhibitory effects of the bacterial endotoxin lipopolysaccharide (LPS)-induced NO production in a screening assay, on inflammation-induced depressive symptoms. We examined the effects of gomisin N on inflammation induced by LPS in murine microglial BV-2 cells and on LPS-induced behavioral changes in mice...

BACKGROUND: Loss of control (LOC) eating in youth is associated with excess body weight and adiposity. After adjusting for fat mass, youth with LOC eating have higher blood pressure and higher low-density lipoprotein cholesterol compared to youth without LOC eating. Increased inflammation may account for this relationship, although few data have examined this hypothesis. Therefore, this study explored the association between LOC eating and high-sensitivity C-reactive protein (hsCRP), a marker of inflammation...

The mechanisms by which inflammation affects the different emotional moods are only partially known. Previous works have pointed to stress hormones like glucocorticoids plus the vascular factor endothelin-1 as key factors evoking stressful states especially in relation to endothelial dysfunctions. With this work, it was our intention to establish the role of pro- and anti-inflammatory cytokine expression variations towards depression-like behaviors and consequently the development of neurodegeneration events caused by endothelial damages in the hamster (Mesocricetus auratus)...

Depression is a major health problem in which oxidative stress and inflammation are inextricably connected in its pathophysiology. Coenzyme Q10 (CoQ10) is an important anti-oxidant compound with anti-inflammatory and neuro-protective properties. This study was designed to investigate the hypothesis that CoQ10 by its anti-oxidant and anti-inflammatory potentials can alleviate depressive- like behavior by restoring the balance of the tryptophan catabolites kynurenine/serotonin toward the serotonin pathway by down-regulation of hippocampal indoleamine 2,3-dioxygenase 1 (IDO-1)...
