Introduction: Patients with bipolar disorder show social cognition deficits during both symptomatic and euthymic phases of the illness, partially independent of other cognitive dysfunctions and current mood. Previous studies in schizophrenia have revealed that social cognition is a modifiable domain. Social cognition and interaction training (SCIT) is an 18-week, manual-based, group treatment designed to improve social functioning by way of social cognition. Method: 37 outpatients with DSM-IV-TR bipolar and schizoaffective disorders were randomly assigned to treatment as usual (TAU)+SCIT (n=21) or TAU (n=16). Independent, blind evaluators assessed subjects before and after the intervention on Face Emotion Identification Task (FEIT), Face Emotion Discrimination (FEDT), Emotion Recognition (ER40), Theory of Mind (Hinting Task) and Hostility Bias (AIHQ). Results: Analysis of covariance revealed significant group effects for emotion perception, theory of mind, and depressive symptoms. The SCIT group showed a small within-group decrease on the AIHQ Blame subscale, a moderate decrease in AIHQ Hostility Bias, a small increase in scores on the Hinting Task, a moderate increase on the ER40, and large increases on the FEDT and FEIT. There was no evidence of effects on aggressive attributional biases or on global functioning. Limitation: No follow up assessment was conducted, so it is unknown whether the effects of SCIT persist over time. Conclusion: This trial provides preliminary evidence that SCIT is feasible and may improve social cognition for bipolar and schizoaffective outpatients. © 2012 Elsevier B.V.

Background/Aims: Several single nucleotide polymorphisms (SNPs) in the PITX3 gene have been associated with the risk for Parkinson's disease (PD). We conducted a systematic review and a meta-analysis including all the studies published on the risk of PD related with these polymorphisms. Methods: The systematic review was done using several databases. Eligible studies were included in the meta-analysis that was carried out using Meta-DiSc 1.1.1 software. Heterogeneity between studies was tested using the Q-statistic. Results: The meta-analysis included eight association studies for the PITX3 rs3758549 SNP (4,052 PD patients, 3,949 controls), eight studies for the PITX3 rs2281983 SNP (4,309 PD patients, 4,287 controls), and six studies for the rs4919621 SNP (2,724 PD patients, 2,285 controls), and the risk for PD, global diagnostic odds ratios (95% confidence intervals) for rs3758549, rs2281983, and rs4919621 were, respectively, 1.00 (0.89-1.12) (p = 0.979), 0.99 (0.91-1.09) (p = 0.896), and 0.98 (0.83-1.16) (p = 0.844) for the total group. The separate analysis in Caucasian and Chinese subjects on the frequency of the minor allele of the three SNPs analyzed did not show significant differences between PD patients and controls in both subgroups. rs2281983 and rs4919621 SNPs were related with early-onset PD risk in Caucasians. Conclusion: The results of the meta-analysis suggest that rs3758549, rs2281983, and rs4919621 SNPs are not major determinants of the risk for PD. © 2013 S. Karger AG, Basel.

Multiple sclerosis (MS) is the prototypical inflammatory disease of the central nervous system and spinal cord, leading to axonal demyelination of neurons. Recently, we have found a correlation between fungal infection and MS in peripheral blood of patients. The present work provides evidence of fungal infection in the cerebrospinal fluid (CSF) of some MS patients. Thus, fungal antigens can be demonstrated in CSF, as well as antibodies reacting against several Candida species. Comparison was made between CSF and blood serum for the presence of fungal antigens (proteins) and antibodies against different Candida spp. Analyses of both CSF and serum are complementary and serve to better evaluate for the presence of disseminated fungal infection. In addition, PCR analyses indicate the presence of DNA from different fungal species in CSF, depending on the patient analyzed. Overall, these findings support the notion that fungal infection can be demonstrated in CSF from some MS patients. This may constitute a risk factor in this disease and could also help in understanding the pathogenesis of MS. © 2013 Springer-Verlag Berlin Heidelberg.

BACKGROUND/AIMS: Several single-nucleotide polymorphisms (SNPs) in the catechol-O-methyltransferase (COMT) gene have been associated with the risk of developing Parkinson's disease (PD). We conducted a systematic review and a meta-analysis including all the studies published on PD risk related with COMT SNPs (mainly rs4680). We also reviewed the possible relationship of COMT SNPs with clinical, neuropharmacological, neurochemical, and neuroimaging features of PD. MATERIALS AND METHODS: The systematic review was conducted using several databases. Meta-analysis of the eligible studies was carried out using the software Meta-Disc 1.1.1. Heterogeneity between studies was tested using the Q-statistic. RESULTS: The meta-analysis included 24 association studies for the COMT rs4680 SNP (9719 PD patients, 14634 controls) and the risk for PD. The frequency of allele positivity showed a significant association between rs4680 and the risk for PD in the total series, as well as homozygosity for the low-activity allele in the Asiatic population (these associations were marginal or disappeared when studies on Hardy-Weinberg disequilibrium were not considered). Global diagnostic odds ratios (95% confidence intervals) for rs4680 were 0.99 (0.94-1.04) for the total group, 0.99 (0.93-1.05) for White, and 1.05 (0.90-1.22) for Asiatic individuals. COMT genotypes could be related with a modest modification in the age at onset of PD, but its possible genotypes in excessive daytime somnolence, impulse control disorders, cognitive impairment, and neuropharmacological or neurochemical variables are unclear. CONCLUSION: The results of the meta-analysis suggest that the COMT rs4680 polymorphism is not a major determinant of either the risk for PD or clinical, neuropharmacological and neurochemical features of PD. Data on other COMT polymorphisms are scarce but do not suggest association with PD. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background: The aim of this study was to assess the impact of a short message service (SMS)-based strategy on adherence to antipsychotic treatment. Methods: A multicentre, randomised, open-label, controlled, 6-month study with clinically stabilised outpatients with schizophrenia was conducted. The patients assigned to the intervention received daily SMS reminders to take their medication for 3 months. Self-reported medication adherence was determined using the Morisky Green Adherence Questionnaire (MAQ). Secondary outcomes were severity of illness, attitude towards medication, insight into illness and health-related quality of life. Results: A total of 254 patients were analysed. A significantly greater improvement in adherence was observed among patients receiving SMS text messages compared with the control group. The mean change in MAQ total score from baseline to month 3 was -1.0 (95% confidence interval (CI) -1.02, -0.98) and -0.7 (95%CI -0.72, -0.68), respectively (P=0.02). Greater improvement in negative, cognitive and global clinical symptoms at month 3 was observed. Attitude towards medication also significantly improved across the study in the intervention group versus the controls. Conclusions: An SMS-based intervention seems feasible and acceptable for enhancing medication adherence. Further studies are needed to confirm whether this kind of intervention could be a complementary strategy to optimise adherence in schizophrenia. © 2012 Elsevier Ireland Ltd.

The pathogenesis of idiopathic restless legs syndrome (iRLS) is not well established, but the most important hypothesis suggests dopaminergic dysfunction and iron deficiency. However, recent reports suggest a possible role for several neurotransmitters or neuromodulators, such as aspartate, glutamate, gamma-hydroxybutyric acid (GABA) and opiates, as well as relation with vitamin D deficiency. In this review, we summarise the studies related to neurochemical findings in iRLS. © 2015 Touch Briefings. All rights reserved.

The high frequency of positive family history of restless legs syndrome (RLS) in patients with this disease and the observed high concordance rates in monozygotic compared with dizygotic twins support a major role of genetic factors in the development of RLS. Although a number of variants for several genes may increase the risk of RLS, no definitive causative genes have been identified to date. In this review, we summarise the studies performed on families with RLS, twin studies, linkage studies, genome-wide association studies, case-control association studies and exome sequencing in RLS. The strongest candidate genes are of PTPRD, BTBD9 and MEIS. © TOUCH MEDICAL MEDIA 2013.

Expert Opinion on Therapeutic Targets | Year: 2015

LINGO-1 is a negative regulator of neuronal survival, oligodendrocyte differentiation and axonal outgrowth and regeneration, because it interacts with diverse growth factor receptors blocking or inhibiting their action. Consistent findings obtained in vitro and in animal models suggest that anti-LINGO-1 therapy may be useful in neurodegenerative disorders such as multiple sclerosis (MS), Parkinson's disease or essential tremor (ET). Moreover, genetic and pathological evidence provide a robust link between LINGO-1 and ET.Areas covered: In this review, we present an overview of current knowledge on findings linking LINGO-1 and ET, with a special focus on genetic linkage, we include an overview of LINGO1 gene variations according to the 1000 genomes catalog, and we identify potential gene areas where common changes occur because, as well as the risk developing ET, LINGO1 genetic changes may influence the response to anti-LINGO-1 therapy.Expert opinion: The goal of anti-LINGO-1 therapy in neurodegenerative diseases is to ease the brakes of neuronal growth and recovery. An anti-LINGO-1 antibody is under clinical trials for MS patients. Before planning trials with ET patients, refinement on the genetic link between LINGO1 and ET, and a detailed genetic and phenotypic assessment of ET patients to be enrolled, should be carried out. © 2015 Informa UK, Ltd.

The relative role of genetic and environmental factors in the pathogenesis of Parkinson's disease (PD) has been the matter of investigation and debate, especially in the last 30 years. The possible interaction between genetic and environmental factors led to a great number of association studies between single nucleotide polymorphisms (SNPs) of many candidate genes and PD risk. In this study we summarized and critically reviewed the results of studies published on this issue, with especial reference to those reported in the last 5 years. Many studies provided conflicting findings and, when positive associations were identified, associations were weak. Polymorphisms related with activation or detoxification of drugs and xenobiotics, such as CYP1A1, CYP1A2, CYP19A1, CYP1B1, CYP2C9, CYP2C19, CYP2E1, CYP2D6, NAT2, GSTM1, GSTM3, GSTO1, GSTP1, PON1, PON2, ABCB1 and ADH genes have not been demonstrated convincingly a definitive association with the risk of developing PD. Nor did polymorphisms in genes related to dopamine or serotonin DRD, DAT, TH, DDC, DBH, MAO, COMT, SLC6A4, MTR, MTHFR, oxidative stress NOQ1, NOQ2, mEPHX, HFE, GPX, CAT, mnSOD, HFE, HO-1, HO-2, NFE2L2, KEAP1, inflammatory processes, ILs, TNF, ACT, NOS, HNMT, ABP1, HRHs, trophic and growth factors BDNF, FGF, or mitochondrial metabolism and function. In addition we analyzed other putative relations and genes associated with monogenic familial PD.Taking together the results of candidate gene association studies and genome wide association studies, only some SNPs of the MAPT, SNCA, HLA and GBA genes seem to be the most likely associated with PD risk. © 2014 Bentham Science Publishers.

Patient Preference and Adherence | Year: 2013

Background: The primary aim of this study was to assess drug treatment adherence in patients with bipolar disorder and to identify factors associated with adherence. The secondary aim was to analyze the impact of suboptimal adherence on clinical and functional outcomes. Methods: A cross-sectional study was conducted in a sample of outpatients receiving an oral antipsychotic drug. Medication adherence was assessed combining the 10-item Drug Attitude Inventory, the Morisky Green Adherence Questionnaire, and the Compliance Rating Scale. Logistic regression was used to determine significant variables associated with suboptimal adherence to medication. Results: Three hundred and three patients were enrolled into the study. The mean age was 45.9 ± 12.8 years, and 59.7% were females. Sixty-nine percent of patients showed suboptimal adherence. Disease severity and functioning were significantly worse in the suboptimal group than in the adherent group. Multivariate analysis showed depressive polarity of the last acute episode, presence of subsyndromal symptoms, and substance abuse/dependence to be significantly associated with suboptimal treatment adherence (odds ratios 3.41, 2.13, and 1.95, respectively). Conclusion: A high prevalence of nonadherence was found in an outpatient sample with bipolar disorder. Identification of factors related to treatment adherence would give clinicians the opportunity to select more adequately patients who are eligible for potential adherencefocused interventions. © 2013 Montes et al, publisher and licensee Dove Medical Press Ltd.
