Pain is a common complication of herpes zoster (HZ) infection which results from reactivation of a latent varicella zoster virus (VZV). A third of HZ patients' progress to a chronic pain state known as post herpetic neuralgia (PHN), and about a quarter of these patients' have orofacial pain. The mechanisms controlling the pain responses are not understood. Studies suggest central pathways involving the thalamus could control pain related to HZ, and studies in our lab suggest vesicular GABA transporter (VGAT) in the lateral thalamus influences orofacial pain...

Tardive dystonia is characterized by sustained, generally slow involuntary twisting movements. It is estimated to occur at a frequency of 1% to 4% among patients who are taking an antipsychotic agent. Unlike the first generation antipsychotics, the second generation antipsychotics are less likely to cause neuroleptic-induced movement disorder. For aripiprazole, only a few cases have been reported for tardive dystonia. We present a young male, who developed a severe tardive dystonia after taking aripiprazole for 5 years...

BACKGROUND: Little is known about the clinical outcomes of severely ill patients with first-episode schizophrenia spectrum disorders (FES) who are considered to lack the capacity to consent to clinical trials. We investigated the feasibility of an algorithm-based pharmacotherapy (ABP) and clinical outcomes of patients with FES involuntarily hospitalized and treated with ABP. METHODS: We conducted a retrospective chart review of 160 patients admitted involuntarily between October 2012 and October 2015...

The ulcerogenic potential of dopamine antagonists and L-NAME in rats provides unresolved issues of anti-emetic neuroleptic application in both patients and experimental studies. Therefore, in a 1-week study, we examined the pressures within the lower oesophageal and the pyloric sphincters in rats [assessed manometrically (cm H2O)] after dopamine neuroleptics/prokinetics, L-NAME, L-arginine and stable gastric pentadecapeptide BPC 157 were administered alone and/or in combination. Medication (/kg) was given once daily intraperitoneally throughout the 7 days, with the last dose at 24 h before pressure assessment...

Importance: Limited treatment responses in schizophrenia prompted the testing of combining an antipsychotic drug treatment with a second psychotropic medication. A comprehensive evaluation of the efficacy of multiple medication combinations is missing. Objective: To summarize and compare the meta-analytically determined efficacy of pharmacologic combination strategies of antipsychotic drugs in adults with schizophrenia. Data Sources: Systematic search of PubMed and PsycInfo until May 13, 2016...

Schizophrenia (SZ) is considered to be a multifactorial brain disorder with defects involving many biochemical pathways. Patients with SZ show variable responses to current pharmacological treatments of SZ because of the heterogeneity of this disorder. Stress has a significant role in the pathophysiological pathways and therapeutic responses of SZ. Atypical antipsychotic drugs (AAPDs) can modulate the stress response of the hypothalamic-pituitary-adrenal (HPA) axis and exert therapeutic effects on stress by targeting the prefrontal cortex (PFC) and hippocampus...

Clozapine has proved to be an effective antipsychotic for the treatment of refractory schizophrenia - characterised by the persistence of symptoms despite optimal treatment trials with at least two different antipsychotics at adequate dose and duration - but its use is hampered by adverse effects. The development of clozapine-induced diabetes is commonly considered to arise as part of a metabolic syndrome, associated with weight gain, and thus evolves slowly. We present the case of an individual with refractory schizophrenia and metformin-controlled diabetes who developed rapid-onset insulin-dependent hyperglycaemia immediately after starting clozapine...

OBJECTIVE: To explore the evidence around clozapine re-challenge following myocarditis. CONCLUSION: This case adds to the 17 cases of clozapine re-challenge following myocarditis, of which 71% were successful (12 cases). This demonstrates that re-challenge could be performed safely and effectively in the context of clozapine-induced myocarditis, if accompanied by a strict and rigorous monitoring protocol.

OBJECTIVE: There is some evidence that clozapine is significantly underutilised. Also, clozapine use is thought to vary by country, but so far no international study has assessed trends in clozapine prescribing. Therefore, this study aimed to assess clozapine use trends on an international scale, using standardised criteria for data analysis. METHOD: A repeated cross-sectional design was applied to data extracts (2005-2014) from 17 countries worldwide. RESULTS: In 2014, overall clozapine use prevalence was greatest in Finland (189...

Chronic psychosocial stress modulates brain antioxidant systems and causes neuroinflammation that plays a role in the pathophysiology of depression. Although the antidepressant fluoxetine (FLX) represents the first-line treatment for depression and the atypical antipsychotic clozapine (CLZ) is considered as a second-line treatment for psychotic disorders, the downstream mechanisms of action of these treatments, beyond serotonergic or dopaminergic signaling, remain elusive. We examined behavioral changes, glutathione (GSH)-dependent defense and levels of proinflammatory mediators in the prefrontal cortex (PFC) of adult male Wistar rats exposed to 21days of chronic social isolation (CSIS)...

The rapidly activating delayed rectifier K(+) channel (IKr) is encoded by the human ether-a-go-go-related gene (hERG), which is important for the repolarization of the cardiac action potential. Mutations in hERG or drugs can impair the function or decrease the expression level of hERG channels, leading to long QT syndrome (LQTS). Thus, it is important to understand hERG channel trafficking and its regulation. For this purpose, G protein-coupled receptors (GPCRs), which regulate a vast array of cellular processes, represent a useful route...

BACKGROUND: The "neurodegenerative diseases plan" under elaboration for the Hauts-de-France region requires better knowledge of the patient population and care pathways. In France, the prevalence of Parkinson's disease (PD) has been estimated from cohorts to be about 1-3 per 1000 inhabitants, but exhaustive data are scarce for the general population. The purpose of this study was to evaluate the prevalence of PD in the Hauts-de-France region and to assess PD-related healthcare consumption...

Antidepressant drugs are widely used in the treatment of different psychiatric disorders, as well as in conjunction with antipsychotics for the treatment of major depressive disorder. In this study, a simple and rapid ultrasound-assisted low-density solvent dispersive liquid-liquid microextraction (UA-LDS-DLLME) method was developed for the simultaneous determination of 12 new antidepressants (norfluoxetine, fluoxetine, fluvoxamine, agomelatine, mirtazapine, moclobemide, melitracen, N-desmethylmirtazapine, maprotiline, sertraline, citalopram, paroxetine) and 2 antipsychotics (clozapine and haloperidol) in human whole blood by gas chromatography-mass spectrometry (GC-MS)...

The dopamine D4 receptor garnered a great deal of interest in the early 1990s when studies showed the atypical antipsychotic clozapine possessed higher affinity for D4, relative to other dopamine receptor subtypes, and that this activity might underlie the unique clinical efficacy of clozapine. Coupled with genetic association of the DRD4 gene with various CNS disorders, multiple companies launched discovery programs to develop selective D4 antagonists. Merck's D4 antagonist L-745,870 was the first to reach the clinic, where it was found to be ineffective in schizophrenia patients, and other groups failed to recapitulate some of the genetic data...

WHAT IS KNOWN AND OBJECTIVE: Neuroleptic malignant syndrome (NMS) is a rare but severe adverse effect of antipsychotic drugs. CASE DESCRIPTION: We report two cases of NMS highlighted by clinical pharmacists in an emergency unit during summer. One of them was fatal. Medication reconciliation processes performed at admission identified treatment with loxapine for one of them and with loxapine and clozapine for the other. Interview of the patients highlighted clinical symptoms suggesting NMS, allowing the pharmacists to alert the medical team...

Background: Clozapine, an antipsychotic used in treatment-resistant schizophrenia, has adverse gastrointestinal effects with significant associated morbidity and mortality. However, its effects on defined patterns of colonic contractile activity have not been assessed. Method: We used novel radial and longitudinal spatiotemporal mapping techniques, combined with and monitoring of ambient lumen pressure, in ex vivo preparations of triply and of singly haustrated portions of rabbit colon. We identified the contractile patterns of mass peristalses, fast phasic, and ripple contractions and directly qualified the effects of clozapine, at concentrations of 10 μmol/L, 20 μmol/L, and 30 μmol/L, and of norclozapine, the main metabolite of clozapine, on contractile patterns...
