The prevalence of cardiovascular disease (CVD) is higher in patients with schizophrenia than in the general population. We aimed to investigate whether atypical antipsychotics (AAP) increase the levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), thereby increasing the risk of CVD. The data were from inpatients aged 18 to 60 years with a diagnosis of schizophrenia according to ICD-10 at The Affiliated Brain Hospital of Nanjing Medical University who underwent physical examination between 1 October 2014 and 30 September 2016...

Psychosis is associated with abnormal structural changes in the brain including decreased regional brain volumes and abnormal brain morphology. However, the underlying causes of these structural abnormalities are less understood. The immune system, including microglial activation, has been implicated in the pathophysiology of psychosis. Although previous studies have suggested a connection between peripheral proinflammatory cytokines and structural brain abnormalities in schizophrenia, no in-vivo studies have investigated whether microglial activation is also linked to brain structure alterations previously observed in schizophrenia and its putative prodrome...

Astrocytes are glial cells that are essential for the maintenance of central nervous system functions, modulating neurotransmitters, providing metabolic, trophic and antioxidant support, and producing a wide range of cytokines to modulate the inflammatory response. These cells can be targets for antipsychotics, medications used in the treatment of neuropsychiatric disorders. In this regard, several studies have shown that antipsychotics are able to modulate peripheral cytokine release, but their effects on astroglial inflammatory response need to be further investigated...

Neuroinflammation has been proposed as a major mechanism in schizophrenic disorder. Specifically, an increase of the inflammatory response in the central nervous system is capable of activating microglial cells, leading to the release of pro-inflammatory cytokines and thus activating apoptotic signaling. An increase in apoptosis, may underlie a potential role of immune neuropathology in the etiopathogenesis of schizophrenia and in specific at the onset of the disorder. We analyzed in whole blood, levels of S100B, the receptor for advanced end glycation products (RAGE) and the apoptotic marker Fas Ligand in a sample of 13 first episode of schizophrenia twice at baseline before the initiation of any antipsychotic medication (A) and 6 weeks later following an antipsychotic monotherapy (B) and in a sample of 10 healthy controls...

There are many theories about the etiology of schizophrenia. This paper presents the assumptions and latest findings about many immunological characteristics of schizophrenia. According to the neuroimunological theory, this disorder is due to neuroimunological disbalance, increased microglial activity and increased levels of proinflammatory cytokines. Studies have found that intrauterine infections in pregnant women have an effect on the fetal brain development, and that infections with rubella, measles, herpes virus, and toxoplasma are associeted with schizophrenia onset in adult life...

Memantine, an uncompetitive antagonist of glutamate receptor of the N-methyl-D-aspartate type is approved for the treatment of moderate to severe Alzheimer disease (1). A growing body of evidence supports a link between the glutamatergic neurotransmission and schizophrenia (2). The aim of this study was to examine the efficacy and safety of memantine as an adjunctive treatment for antipsychotics in patient with psychopathology of schizophrenia and schizoaffective. In this study, we assessed the effect of memantine on the pro-inflammatory cytokines such as IL6, TNFα and CRP...

The precise effect of antipsychotic drugs on either central or peripheral inflammation remains unclear. An important issue in this debate is to what extent the known peripheral metabolic effects of antipsychotics, including increased adiposity, may contribute to increased inflammation. Adipose tissue is known to contribute to the development of systemic inflammation, which can eventually lead to insulin resistance and metabolic dysregulation. As a first step to address this question, we evaluated whether chronic exposure to clinically comparable doses of haloperidol or olanzapine resulted in the immune activation of rat adipose tissue...

REVIEW
Xu-Feng Huang, Xueqin Song
Although antipsychotic drugs are mainly used for treating schizophrenia, they are widely used for treating various psychiatric diseases in adults, the elderly, adolescents and even children. Today, about 1.2% of the worldwide population suffers from psychosis and related disorders, which translates to about 7.5 million subjects potentially targeted by antipsychotic drugs. Neurites project from the cell body of neurons and connect neurons to each other to form neural networks. Deficits in neurite outgrowth and integrity are implicated in psychiatric diseases including schizophrenia...

Schizophrenia is one of the most serious and common mental disorders, which is characterized by high levels of pathogenic heterogeneity as well as neuroimmune abnormalities, which require treatment with antipsychotic drugs. Monoamines are one of the key neurotransmitters which play an important role in neuroimmune interactions of the human organism. We suggest that the quantity of the monoamine receptors on mononuclear cells of the peripheral blood (PBMCs) can be associated with the cytokine profile of patients...

In schizophrenia, plasma cytokines abnormalities offer vital support for immunopathogenetic basis. However, most of the previous studies on plasma cytokines are confounded by examination of antipsychotic-treated schizophrenia patients. In this study, we examined a large sample of antipsychotic-naïve/free schizophrenia patients (N = 75) in comparison with healthy controls (N = 102). Plasma cytokines (Interleukins ([IL] 2, 4, 6, 10, 17), Tumor necrosis factor [TNF] and Interferon gamma [IFN-g]) were assessed using cytometric bead array assay...

This paper discusses the current evidence from animal and human studies for a central role of inflammation in schizophrenia. In animal models, pre- or perinatal elicitation of the immune response may increase immune reactivity throughout life, and similar findings have been described in humans. Levels of pro-inflammatory markers, such as cytokines, have been found to be increased in the blood and cerebrospinal fluid of patients with schizophrenia. Numerous epidemiological and clinical studies have provided evidence that various infectious agents are risk factors for schizophrenia and other psychoses...

INTRODUCTION: Patients with Alzheimer disease (AD) suffer from psychotic symptoms including pain. The current antipsychotic drugs confer limited effectiveness, and hence new strategies are being designed to decrease pain in order to increase antipsychological effectiveness. Vitamin B12 is a safe supplementary drug to decrease pain. Additionally, cytokines participate in the pathogenesis of immune-related diseases such as AD. Thus, the main aim of this clinical trial study was to determine the effects of treatment with risperidone and quetiapine, as antipsychotic drugs, with and without vitamin B12 on the psychotic symptoms of AD patients and the expression of IL-6, IL-8, tumor growth factor (TGF)-β, tumor necrosis factor (TNF)-α, and endothelin (ET)-1)...

PURPOSE: Chronic, low-grade inflammation is a proposed etiological factor associated with schizophrenia. Thus, various studies have been conducted to understand the role of inflammatory process in schizophrenia by using inflammatory maker C-reactive protein (CRP) with conflicting findings. Inadvertently, studies of CRP among the Indian schizophrenia patients are very few. Therefore, the present study was undertaken to investigate the role of inflammatory process among Indian Bengalee schizophrenia patients of Siliguri, using the marker CRP and its stimulating cytokine interleukin-6 (IL-6)...

Olanzapine (OLZ) is efficacious whereas leads to adverse metabolic effects thus lead to higher risk of cardiovascular diseases (CVD) on schizophrenia. Cytokines have been found associated with metabolic disorders. Therefore, pretreatment prediction of OLZ-induced adverse metabolic effects is urgently needed. To investigate if baseline cytokine levels could become biomarkers for pathogenesis of schizophrenia or prediction for OLZ-induced adverse metabolic effects, we recruited 75 participants, including 23 schizophrenia inpatients, who were antipsychotic-free over the past 6 months or first episode and drug-naive and 52 matched health controls, in our prospective cohort study and cross-sectional study...

BACKGROUND: Numerous studies have suggested that an immune system imbalance plays an important role in schizophrenia. Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine. It plays multiple roles in various biological processes, including inflammation and neurogenesis. Furthermore, several exhaustive serum proteomic profiling studies have identified MIF as a potential biomarker of schizophrenia. Here, we investigate MIF protein levels in serum and postmortem prefrontal cortex in patients with schizophrenia and controls...

BACKGROUND: The etiopathogenesis of psychiatric disorders is still not completely understood. Growing evidence supports the hypothesis that mental illness and related disturbances in the brain neurobiology do not necessarily originate in the brain. Inflammation has been suggested to play a central role in psychiatric disorders, and altered levels of peripheral cytokines have been reported in several studies. OBJECTIVE AND METHODS: In this review, we present and discuss studies exploring the role of dysbiosis and products of the gut-microbiota in the pathogenesis of psychiatric disorders, as well as its potential involvement in mediating the effect of antidepressants, mood stabilizers, and antipsychotics...

Preclinical and clinical evidence suggests pro-inflammatory cytokines might play an important role in the neurobiology of schizophrenia and stress-related psychiatric disorders. Interleukin-18 (IL-18) is a member of the IL-1 family of cytokines and it is widely expressed in brain regions involved in emotional regulation. Since IL-18 involvement in the neurobiology of mental illnesses, including schizophrenia, remains unknown, this work aimed at investigating the behavior of IL-18 null mice (KO) in different preclinical models: 1...
