Dopamine supersensitivity psychosis (DSP) is a type of acute exacerbation of recurrent psychosis caused by long-term treatment with antipsychotics in schizophrenic patients. Although DSP is exceedingly troublesome for clinicians, effective treatment has not yet been established. Based on clinical research and our animal study, we hypothesize that aripiprazole, an atypical anti-psychotic, may reduce the exacerbation of recurrent psychotic episodes. We report the case of a 46-year-old female who suffered from schizophrenia with DSP. In this case, sustained treatment with a high dose of aripiprazole gradually reduced the severity of her recurrent psychotic episodes. In conclusion, sustained treatment with aripiprazole may reduce the exacerbation of recurrent psychotic episodes in schizophrenic patients with DSP, and may be an effective treatment of DSP.

Neuroleptic Malignant Syndrome Associated with Valproate in an Adolescent.
Clinical Psychopharmacology and Neuroscience.2017;15(1):76-78. doi:10.9758/cpn.2017.15.1.76
Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction that usually occurs after the administration of antipsychotic drugs. Antidepressants, benzodiazepines, and antiepileptic drugs are also suggested to be associated with NMS. It is believed to result from a dopaminergic blockade in the central nervous system. NMS is manifested by hyperthermia, muscle rigidity, autonomic dysfunction, altered mental status, leukocytosis, and elevated serum creatinine phosphokinase. Valproate is commonly used in the treatment of many psychiatric and neurologic disorders. Valproate can precipitate NMS, especially when used with antipsychotic drugs concurrently. A 17-year-old male patient, who presented with fever, muscular rigidity, confusion, sweating, and tachycardia was admitted to the emergency room. He had been taking only valproate for the last two months for bipolar disorder. His laboratory analyses revealed raised serum hepatic enzymes, creatinine phosphokinase, and myoglobin levels. Considering fever, rigidity, autonomic dysfunction, cognitive alteration, and high creatinine phosphokinase levels, the patient was diagnosed with NMS. In this paper, we aim to discuss the association between valproate and NMS.

Mirtazapine Is Effective in Steroid Withdrawal Syndrome Related Depression: A Case Report.
Clinical Psychopharmacology and Neuroscience.2017;15(1):73-75. doi:10.9758/cpn.2017.15.1.73
Steroid withdrawal syndrome (SWS) following steroid dependence is becoming a common clinical condition. It may be associated with body image disorder. Though selective serotonin reuptake inhibitors (SSRIs) are found to be effective SWS associated depression, data for this clinical condition is limited. We present a case of SWS associated with body image disorder which improved with mirtazapine. Mirtazapine might be better option than SSRIs in this subgroup of patients for its noradrenergic property and better gastrointestinal profile. More research should explore its efficacy in this clinical condition.

Mania in Wolfram's Disease: From Bedside to Bench.
Clinical Psychopharmacology and Neuroscience.2017;15(1):70-72. doi:10.9758/cpn.2017.15.1.70
Wolfram syndrome is a relatively unexplored entity in clinical psychiatry. Historically, the discovery of a specific WFS1 gene had generated huge fanfare regarding specific genetic causations of psychiatric disorders. While the initial enthusiasm has faded now, association of Wolfram syndrome with psychiatric illnesses like schizophrenia, psychosis and suicidal behavior still remain important for understanding biological underpinnings of such disorders. We report a case of Wolfram syndrome presenting with multiple manic episodes, discuss possible genetic underpinnings for the affective symptoms and then discuss certain issues regarding management.

Disulfiram is the commonly prescribed drug for the treatment of alcohol dependence. It's major metabolite (diethyldithiocarbamate) is an inhibitor of dopamine-betahydroxylase, an enzyme that catalyzes the metabolism of dopamine to norepinephrine resulting in psychosis. We recommend that disulfiram should be used at the lowest effective dose, possibly 250 mg daily and caution should be taken while prescribing disulfiram for patients with personal and familial antecedents of psychosis.

OBJECTIVE: Prenatal infection is implicated in the etiology of schizophrenia. The objective of this paper is to study the role of complement protein C1q in the psychosis of adult offspring after maternal immune activation (MIA). In addition, effect of 7,8-dihydroxyflavone (7,8-DHF: a tropomyosin receptor kinase B [TrkB] agonist) was also examined. METHODS: Western blot analysis of C1q in the brain regions from adult offspring after prenatal poly(I:C) (5.0 mg/kg/day from E12 to E17) exposure was performed. 7,8-DHF or vehicle was given from 4 to 8-weeks old. RESULTS: Expression of C1q in the prefrontal cortex (PFC) of adult offspring from poly(I:C)-treated pregnant mice was significantly higher than that of control group. Early treatment with 7,8-DHF during juvenile and adolescent stages could prevent an increase of C1q in the PFC of adult offspring after MIA. CONCLUSION: Therefore, it is likely that increased C1q expression in the frontal cortex may play a role in the behavioral abnormalities of adult offspring after MIA. Furthermore, supplementation with a TrkB agonist such as 7,8-DHF during the prodromal stage may have prophylactic effects on the behavioral abnormalities after MIA.

OBJECTIVE: The present study aims to analyze the levels of resistin, tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, IL-18, and C-reactive protein (CRP) in patients with Alzheimer's disease (AD) and also investigate a potential relationship between resistin levels and TNF-α, IL-1β, IL-6, IL-18, and CRP levels in patients with AD. METHODS: The study included fifty patients with AD and 30 healthy controls with normal cognitive functions. The serum resistin, TNF-α, IL-1β, IL-6, IL-18, and CRP levels were assessed. We performed a Mini-Mental State Examination (MMSE) to evaluate the general cognitive performance. RESULTS: The mean serum resistin, IL-1β, IL-18, and TNF-α levels were significantly higher in patients with AD compared with the controls (p=0.026, p=0.002, p=0.003, and p=0.038, respectively). The IL-6 and CRP levels did not differ between the groups (p=0.874 and p=0.941). The resistin levels were positively correlated with the levels of CRP and IL-18 (r=0.526, p<0.001; r=0.402, p=0.004, respectively). MMSE scores and inflammatory markers were not correlated (p>0.05 for all). CONCLUSION: Serum resistin levels were significantly increased and correlated with some inflammatory markers in AD patients, suggesting that resistin might play a role in the inflammatory process of AD.

Association of CDKN2B-AS1 rs1333049 with Brain Diseases: A Case-control Study and a Meta-analysis.
Clinical Psychopharmacology and Neuroscience.2017;15(1):53-58. doi:10.9758/cpn.2017.15.1.53
OBJECTIVE: CDKN2B-AS1 polymorphisms were shown to associate with the risk of stroke in European. The goal of this study was to evaluate the contribution of CDKN2B-AS1 rs1333049 to the risk of hemorrhagic stroke (HS) and brain tumor (BT) in Han Chinese. METHODS: A total of 142 HSs, 115 BTs, and 494 controls were included in the current association study. The genotyping test was performed using the melting temperature shift method. RESULTS: We failed to validate the association of CDKN2B-AS1 rs1333049 with the risk of brain disease. Significantly higher levels of low-density lipoprotein cholesterol (LDL-C) (p=0.027), high-density lipoprotein cholesterol (HDL-C) (p<0.001) and total cholesterol (TC) (p<0.001) were found in HSs in the genotype GG/GC carriers, but not the genotype CC carriers (p>0.05). The meta-analysis of 10 studies among 133,993 individuals concluded that rs1333049 of CDKN2B-AS1 gene was likely to increase a 16% incidence rate of cerebrovascular disease (CD) among various populations (odds ratio 1.16, 95% confidence interval 1.08–1.25; p<0.0001, random-effect method). CONCLUSION: Our case-control study identified rs1333049 genotypes showed different association with the concentration of the LDL-C, HDL-C and TC in the HS patients. Meta-analysis supported the association between rs1333049 and CD risk in various populations, although we were unable to observe association between rs1333049 and the risk of HSs in Han Chinese.

OBJECTIVE: The aim of this study was to identify a transcriptomic signature that could be used to classify subjects with autism spectrum disorder (ASD) compared to controls on the basis of blood gene expression profiles. The gene expression profiles could ultimately be used as diagnostic biomarkers for ASD. METHODS: We used the published microarray data (GSE26415) from the Gene Expression Omnibus database, which included 21 young adults with ASD and 21 age- and sex-matched unaffected controls. Nineteen differentially expressed probes were identified from a training dataset (n=26, 13 ASD cases and 13 controls) using the limma package in R language (adjusted p value <0.05) and were further analyzed in a test dataset (n=16, 8 ASD cases and 8 controls) using machine learning algorithms. RESULTS: Hierarchical cluster analysis showed that subjects with ASD were relatively well-discriminated from controls. Based on the support vector machine and K-nearest neighbors analysis, validation of 19-DE probes with a test dataset resulted in an overall class prediction accuracy of 93.8% as well as a sensitivity and specificity of 100% and 87.5%, respectively. CONCLUSION: The results of our exploratory study suggest that the gene expression profiles identified from the peripheral blood samples of young adults with ASD can be used to identify a biological signature for ASD. Further study using a larger cohort and more homogeneous datasets is required to improve the diagnostic accuracy.
