BACKGROUND: Inflammatory bowel disease (IBD) patients with persistent symptoms despite no or minimal inflammation are frequently described as having an overlap of IBD and irritable bowel syndrome (IBD-IBS). Limited data are available on how IBS impacts the individual patient with IBD. In this study, we aimed to evaluate the prevalence of IBD-IBS and investigate its impact on patient-reported outcomes. METHOD: We performed a cross-sectional analysis within the CCFA Partners Study...

Anhedonia, characterized by a loss of interest and/or pleasure in previously enjoyable activities, is an important diagnostic criterion of Major Depressive Disorder (MDD). Converging evidence implicates a behaviouralcausal relationship between proinflammatory cytokines and disturbances that characterize anhedonia in the context of MDD. Additionally, anhedonia has been implicated in disturbances of key central dopaminergic modulatory pathways. Emerging research into the roles of tetrahydrobiopterin, a cytokine-targeted co-enzyme in the synthesis of dopamine, and kynurenine, a product of inflammation-sensitive breakdown of tryptophan via indoleamine 2, 3-dioxygenase, have shed new light into the role of inflammation in mediating anhedonic behaviours...

We aimed to identify statistical predictor variables of LPS-induced physical sickness symptoms during the acute and late inflammatory phases using multivariate regression analyses. Data from N=128 healthy volunteers who received i.v. LPS injection (0.4 or 0.8 ng/kg) or placebo were pooled for analyses. Physical sickness symptoms experienced during the acute (0-6h post-injection) and late (6-24h post-injection) phases were assessed with the validated General-Assessment-of-Side-Effects (GASE) questionnaire. LPS-treated subjects reported significantly more physical sickness symptoms...

There is a growing interest in understanding the role of inflammation in diet-depression relationship. The present study examined whether the dietary inflammatory index (DII, a measure of the inflammatory potential of individuals' diets) is associated with recurrent depressive symptoms (DepS) (CES-D score>16 or taking antidepressants both at baseline and follow-up) assessed over 5 years in middle-aged men (n=3178) and women (n=1068) from the Whitehall II Study. For each increment of 1 SD of DII score, odds of recurrent DepS increased by 66% (95 % CI:1...

A body of evidence has implicated dietary deficiency in omega-3 polyunsaturated fatty acids (n-3 PUFA), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in the pathophysiology and etiology of recurrent mood disorders including major depressive disorder (MDD) and bipolar disorder. Cross-national and cross-sectional evidence suggests that greater habitual intake of n-3 PUFA is associated with reduced risk for developing mood symptoms. Meta-analyses provide strong evidence that patients with mood disorders exhibit low blood n-3 PUFA levels which are associated with increased risk for the initial development of mood symptoms in response to inflammation...

BACKGROUND: Hidradenitis suppurativa (HS) is a debilitating chronic disease that leads to inflammation and abscess formation in the involved skin, along with a malodorous discharge. Pain is a considerable aspect of HS and significantly impacts quality of life. In addition, HS is significantly associated with depression. A better understanding of contributing factors to depression and pain in patients with HS can identify opportunities to improve care for patients. OBJECTIVE: To identify factors that contribute to depression and chronic pain in patients with HS...

INTRODUCTION: Inflammation of the central nervous system is increasingly regarded as having a role in cognitive disorders such as dementia and depression, but it is not clear how such inflammation relates to other aspects of neuropathology, structural and functional changes in the brain and symptoms (as assessed via clinical and neuropsychological assessment and MRI). This study will explore these pathophysiological mechanisms using positron emission tomography (PET) which allows in vivo imaging of inflammation, amyloid and τ deposition, together with neuropsychological profiling, MRI and peripheral biomarker analysis...

Sepsis, in addition to causing fatality, is an independent risk factor for cognitive impairment among sepsis survivors. The pathologic mechanism of endotoxemia induced acute neuro-inflammation still has not been fully understood. For the first time, we found the disruption of neurotransmitters 5-HT, impaired neurogenesis and activation of astrocytes coupled with concomitant neuro-inflammation were the potential pathogenesis of endotoxemia induced acute neuro-inflammation in sepsis survivors. In addition, dioscin a natural steroidal saponin isolated from Chinese medicinal herbs, enhanced the serotonergic system and produced anti-depressant effect by enhancing 5-HT levels in hippocampus...

PURPOSE: Depression is frequently associated with inflammation, whereas omega-3 polyunsaturated fatty acids (PUFAs) primarily found in fish oil possess anti-inflammatory properties. Although converging studies suggest an antidepressant effect of PUFAs, there is limited evidence directly linking the neuro-immune modulating features of PUFAs to the antidepressant actions. METHODS: Therefore, we assessed the effects of fish oil (FO) supplementation on behavioral changes, inflammatory cytokine expression and oxidative reactions in frontal cortex and hippocampus of rats following repeated peripheral immune challenge by lipopolysaccharide (LPS) for 2 weeks (500 μg/kg every other day)...

A recent study demonstrated that advanced glycation end products (AGEs) play a role in monocyte infiltration in mesangial areas in diabetic nephropathy. The Ras homolog gene family, member A Rho kinase (RhoA/ROCK) pathway plays a role in regulating cell migration. We hypothesized that the RhoA/ROCK pathway affects adhesion and inflammation in endothelial cells induced by AGEs. Rat glomerular endothelial cells (rGECs) were cultured with AGEs (80 μg/ml) in vitro. The ROCK inhibitor Y27632 (10 nmol/l) and ROCK1-siRNA were used to inhibit ROCK...

OBJECTIVE: Increasing evidence suggests that chronic exposure to unfair treatment or day-to-day discrimination increases risk for poor health, but data on biological stress mechanisms are limited. This study examined chronic experiences of unfair treatment in relation to allostatic load (AL), a multisystem index of biological dysregulation. METHOD: Data are from a sample of 233 African-American adults (37-85 years; 64% women). Perceptions of everyday unfair treatment were measured by questionnaire...

Depressive disorders represent a frequent comorbidity of both type 1 (T1D) and type 2 diabetes (T2D). Inflammation-related processes have been implicated in the development of both diabetes and depression. This study aimed to investigate whether biomarkers of subclinical inflammation were associated with depressive symptoms in individuals with recently diagnosed diabetes and if such associations differed by diabetes type. This cross-sectional study was based on 295 individuals with T2D (67% men, mean age 53years) and 139 individuals with T1D (60% men, mean age 36years) of the German Diabetes Study...

Mental disorders including depression and anxiety are the prevalent human diseases which are associated with several metabolic and non-metabolic diseases. Recent investigations demonstrated that the mental disorders can be considered as the potential inducers/stimulators of chronic inflammation. Based on the fact that chronic inflammation is a main cause of human diseases, hence, a hypothesis has been raised to explore the interaction between mental disorders and inflammation related metabolic diseases. Type 2 diabetes (T2D), as a complicated metabolic disorder, is associated with inflammation and also mental disorders...

Diabetes mellitus, a metabolic disorder, is associated with neurological complications such as depression, anxiety, hypolocomotion, cognitive dysfunction, phobias, anorexia, stroke, pain, etc. Traditional system of medicine is long known for its efficient management of diabetes. The current review discusses the scope of some common medicinal herbs as well as secondary metabolites with a special focus on diabetes-mediated central nervous system complications. Literatures suggest that natural products reduce diabetes-mediated neurological complications partly by reducing oxidative stress and/or inflammation or apoptosis in certain brain regions...

: Abnormalities of T cell-mediated immune activation, in the absence of active somatic immune diseases, have consistently been reported in mood disorders. Apart from being important players in the regulation of cells of the immune system, T cells are essential for normal brain development. We here report studies on the relationship between circulating levels of T helper cells and structural and functional brain imaging in depressed bipolar patients. Since the CCL20-CCR6 axis is an important entry to the brain we differentiated the various T helper cell subpopulations on the basis of their chemokine receptor expression...

Scientific interest in serotonergic psychedelics (e.g., psilocybin and LSD; 5-HT2A receptor agonists) has dramatically increased within the last decade. Clinical studies administering psychedelics with psychotherapy have shown preliminary evidence of robust efficacy in treating anxiety and depression, as well as addiction to tobacco and alcohol. Moreover, recent research has suggested that these compounds have potential efficacy against inflammatory diseases through novel mechanisms, with potential advantages over existing antiinflammatory agents...

The critical factor considered in a depression induced by diabetes is the inflammation eliciting hippocampal, amygdala and thalamic neuronal injury. Therefore, inhibiting inflammatory reactions in the brain and reducing neuronal injury can alleviate depression in rodents suffering from diabetes mellitus. The oral administration of astaxanthin has been employed in emotional disorders and diabetic complications due to its anti-depressant, anti-inflammatory and anti-apoptotic functions. However, it has not been reported whether astaxanthin can improve diabetes-related depression-like behavior, and its potential mechanisms have not been elucidated...

Brain inflammation is an important factor in the conversion of a healthy brain into an epileptic one, a phenomenon known as epileptogenesis, offering a new entry point for prognostic tools. The development of anti-epileptogenic therapies to treat before or at disease onset is hampered by our inability to predict the severity of the disease outcome. In a rat model of temporal lobe epilepsy we aimed to assess whether in vivo non-invasive imaging of brain inflammation at disease onset was predictive of spontaneous recurrent seizures (SRS) frequency and severity of depression-like and sensorimotor-related comorbidities...

OBJECTIVE: The effects of psychological stress, oxidative stress, and chronic low grade inflammation on the neuro-immune connection have been implicated in the pathogenesis of depression. Thus, in the recent past, there has been a growing effort in determining the mechanism of this pathogenesis. While attempting to map out, this mechanism researchers and clinicians have searched for clinically relevant biomarkers for use in the diagnosis and for the assessment of those suffering from depression...
