OBJECTIVES: To assess cytokine and chemokine levels in youth experiencing antipsychotic-induced weight gain (AIWG) compared to obese patients, hypothesizing a different "immune signature" between the two kinds of obesity. METHODS: We compared a group of youth experiencing AIWG (N 19, mean age 159 months, mean body mass index [BMI] z-score 1.81) and an age-, gender-, and BMI-matched group of untreated obese patients (N 19, mean age 147 months, mean BMI z-score 2) for a wide range of cytokines and chemokines by using a multiplex ELISA test...

The microglial hypothesis of schizophrenia suggests that its neuropathology is closely associated with neuroinflammation manifested, inter alia, by an increased expression of cytokines. However, clinical investigations imply that schizophrenia is a heterogeneous disease and in some groups of patients the activated inflammatory process does not contribute to the disease-associated impairment of brain function. Clinical studies revealed also an equivocal impact of antipsychotics on peripheral and CSF cytokines, whereas experimental research performed on the stimulated glia cultures showed their inhibitory effect on pro-inflammatory cytokine levels...

The existence of a restrained inflammatory state in schizophrenic individuals posed the question whether anti-inflammatory drugs may exert antipsychotic effects. Therefore, the effect of ibuprofen (IB) on cytokine production by human peripheral blood mononuclear cells (PBMC) from schizophrenic patients was examined and compared to that of healthy subjects. PBMC from 25 schizophrenic patients and 24 healthy volunteers were incubated for 24 h with lipopolysaccharide (LPS) in the absence or presence of various concentrations of IB...

Schizophrenia is likely to be associated with immunological abnormalities. However, antipsychotics may induce immunomodulatory effects, by influencing plasma cytokines. In order to distinguish these influences, we carried out a systematic review and meta-analysis exploring the acute effect of antipsychotics on candidate cytokines plasma levels (IL-1β, IL-2, IL-6, IL-17, IFN-γ, TNF-α) among drug-naïve subjects with first episode psychosis. We searched main Electronic Databases, identifying eight studies meeting our inclusion criteria...

Olanzapine, a frequently used second-generation antipsychotic, has rarely been implicated as a cause of drug-induced fever in the absence of neuroleptic malignant syndrome. We describe a patient who developed isolated fever following olanzapine monotherapy, which subsided after discontinuation of olanzapine. Blockade of dopaminergic receptors and elevated cytokines concentration are possible mechanisms of fever development during treatment with olanzapine. This case calls for attention to olanzapine-induced fever in clinical practice...

The proinflammatory cytokine tumour necrosis factor-alpha (TNFα) has long been characterized for its role in the innate immune system, but more recently has been found to have a distinct role in the nervous system that does not overlap with other proinflammatory cytokines. Through regulation of neuronal glutamate and GABA receptor trafficking, TNF mediates a homeostatic form of synaptic plasticity, but plays no direct role in Hebbian forms of plasticity. As yet, there is no evidence to suggest that this adaptive plasticity plays a significant role in normal development, but it does maintain neuronal circuit function in the face of several types of disruption...

Cortical grey matter volume deficits and neuro-inflammation exist in patients with schizophrenia, although it is not clear whether elevated cytokines contribute to the cortical volume reduction. We quantified cortical and regional brain volumes in fixed postmortem brains from people with schizophrenia and matched controls using stereology. Interleukin (IL)-6, IL-1β, IL-8 and SERPINA3 messenger RNAs (mRNAs) were quantified in the contralateral fresh frozen orbitofrontal cortex. We found a small, but significant reduction in cortical grey matter (1...

BACKGROUND: Antipsychotic drugs can cause hyperprolactinemia. However, hyperprolactinemia was also observed in treatment-naive patients with a first schizophrenic episode. This phenomenon might be related to the role of prolactin as a cytokine in autoimmune diseases. Extrapituitary prolactin production is regulated by an alternative promoter, which contains the functional single nucleotide polymorphism -1149 G/T (rs1341239). We examined whether this polymorphism was associated with hyperprolactinemia in patients with schizophrenia...

OBJECTIVE: Schizophrenia is a chronic psychotic disorder in which genetics and environmental factors such as infection and the corresponding immune response play a role in the etiopathogenesis. The aim of this study was to compare some immune factors such as nuclear factor-B (NF-B) activation, myeloperoxidase (MPO), the anti-inflammatory cytokine interleukin-4 (IL-4), and regulatory cytokine transforming growth factor- (TGF-) in schizophrenia patients and an age- and gender-matched control group...

Antipsychotic medications (APs), particularly second-generation APs, are associated with significant weight gain in schizophrenia patients. Recent evidence suggests that the immune system may contribute to antipsychotic-induced weight gain (AIWG) via AP-mediated alterations of cytokine levels. Antipsychotics with a high propensity for weight gain, such as clozapine and olanzapine, influence the expression of immune genes, and induce changes in serum cytokine levels to ultimately down-regulate neuroinflammation...

This study evaluated the levels of two amino acid derivatives taurine and spermine in first-episode psychosis (FEP) patients and their response to antipsychotic treatment. The levels of taurine and spermine were significantly up-regulated in antipsychotic-naïve FEP patients compared to control subjects (CS). Treatment of FEP patients with antipsychotic drugs significantly reduced the positive symptoms of schizophrenia. This positive effect was accompanied by a significant reduction of taurine and spermine to the levels measured in CS...

The implications of oxidative stress and neuro-inflammation in the pathogenesis of schizophrenia have been elucidated. Despite their effectiveness against positive symptoms of schizophrenia, antipsychotics have limited effectiveness against negative and cognitive symptoms and are associated with remarkable adverse effects. The use of celecoxib or omega-3 in schizophrenia may have beneficial effects. This study aimed to evaluate the possible efficacies of celecoxib, omega-3 or the combination of celecoxib+risperidone and omega-3+ risperidone compared to risperidone on the behavior and brain biochemistry in rats...

Alterations in the innate inflammatory response may underlie the pathophysiology of psychiatric diseases. Current antipsychotics modulate pro-/anti-inflammatory pathways, but their specific actions on these pathways remain only partly explored. This study was conducted to elucidate the regulatory role of paliperidone (1 mg/kg i.p.) on acute (6 h) and chronic (6 h/day for 21 consecutive days) restraint stress-induced alterations in 2 emerging endogenous anti-inflammatory/antioxidant mechanisms: nuclear factor erythroid-related factor 2 (NRF2)/antioxidant enzymes pathway, and the cytokine milieu regulating M1/M2 polarization in microglia, analyzed at the mRNA and protein levels in prefrontal cortex samples...

Antipsychotic drugs have been used in the treatment of schizophrenia and their long-term use can cause movement disorders, such as tardive dyskinesia (TD) in humans mainly typical ones such as haloperidol. Neuroinflammation has been implicated to the use of antipsychotics besides its participation in TD remains unclear. Thus, the aim of this study was to investigate the relation of cytokines with vacuous chewing movements (VCMs) in rats comparing typical and atypical antipsychotics. Rats were treated with haloperidol or risperidone for 28 days...

BACKGROUND: In schizophrenia, genetic background may provide a substrate for intrinsic maldevelopment of the brain through environmental influences, by recruiting neurotrophic factors and cytokines, to trigger the changes that lead to impaired neuronal functions. Cytokines being the key regulators of immune/inflammatory reactions are also known to influence the dopaminergic, noradrenergic, and serotonergic neurotransmission. Therefore, functional polymorphisms in cytokine genes may result in imbalances in the pro- and anti-inflammatory cytokine production...

Although there is a cumulative evidence for the inflammation pathophysiology in schizophrenia, it has not been conclusively proven yet. One reason for this is the lack of studies that have controlled for major confounding factors such as obesity, smoking, antipsychotic use, and stress. The studies in which the major confounding factors were controlled were done in subjects in acute relapse and in treatment-resistant schizophrenia. To date, no studies have been done in stable outpatients with schizophrenia controlling for major confounding factors...

Inflammation has been considered important in the pathogenesis of schizophrenia. Increasing evidence reveals that patients with schizophrenia have abnormal expression of cytokines, which are related to development of metabolic abnormalities. Metabolic abnormality has become a critical issue, though its longitudinal relationship with the disorder, such as the antipsychotics influence, is unclear. We aimed to investigate whether abnormalities of metabolic parameters and cytokine levels in acute exacerbated schizophrenic patients existed, and whether intervention of antipsychotic could help...
