Selected AbstractsOutcome of suicidal patients with schizophrenia: results from a naturalistic studyACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2010R. Schennach-Wolff Schennach-Wolff R, Jäger M, Seemüller F, Obermeier M, Schmauss M, Laux G, Pfeiffer H, Naber D, Schmidt LG, Gaebel W, Klosterkötter J, Heuser I, Maier W, Lemke MR, Rüther E, Klingberg S, Gastpar M, Möller H-J, Riedel M. Outcome of suicidal patients with schizophrenia: results from a naturalistic study. Objective:, Purpose was to assess suicidality before and at the time of admission in patients with schizophrenia and compare outcome differences. Method:, Biweekly PANSS (Positive and Negative Syndrome Scale), HAMD (Hamilton Depression Rating Scale) and UKU (Udvalg for Klinske Undersogelser Side Effect Rating Scale) ratings were evaluated in 339 in-patients with schizophrenic spectrum disorders. Response was defined as an initial 20% PANSS total score reduction at discharge, remission was defined according to the proposed consensus criteria by the Remission in Schizophrenia Working Group. Results:, Suicidal patients (22%) scored significantly higher on the PANSS negative subscore, PANSS insight item and HAMD total score at admission and at discharge. They developed significantly more side effects. No differences were found concerning response and remission between the two patient subgroups. Conclusion:, Despite receiving significantly more antidepressants the suicidal patients suffered from significantly more depressive symptoms up to discharge, yet without differing regarding response and remission. [source] Divalproex Sodium Extended-Release for the Prophylaxis of Migraine Headache in Adolescents: Results of a Stand-Alone, Long-Term Open-Label Safety StudyHEADACHE, Issue 1 2009George Apostol MD Objective., The objective of this long-term open-label study in adolescents was to assess the safety and tolerability of divalproex sodium extended-release in the prophylaxis of migraine headaches. Background., Two formulations of divalproex sodium have demonstrated efficacy in the prevention of migraine headaches in adults. However, no medications are currently approved for this indication in adolescents, and long-term safety data on agents for migraine prevention are lacking for this younger population. Therefore, the current study was conducted to assess the long-term safety and tolerability of divalproex extended-release in adolescents with migraine headaches. Methods., This was a 12-month, phase 3, open-label, multicenter study of adolescents aged 12 to 17 years with migraine headaches diagnosed by International Headache Society criteria. Divalproex sodium extended-release was initiated at 500 mg/day for 15 days then increased to 1000 mg daily, with subsequent adjustments permitted within a dosing range of 250-1000 mg daily. Study visits were conducted at days 1 and 15 and months 1, 2, 3, 6, 9, and 12. Safety was evaluated by adverse event collection, laboratory assessments, physical and neurological examinations, vital signs, electrocardiograms, the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale, the Wechsler Abbreviated Scale of Intelligence, and the Behavioral Assessment Scale for Children. Efficacy was evaluated by following the number of migraine headache days reported in subjects' headache diaries over sequential 4-week intervals for the duration of the trial. Results., A total of 241 subjects were enrolled and treated. The most frequently reported adverse events were nausea (19%), vomiting (18%), weight gain (12%), nasopharyngitis (11%), migraine (10%), and upper respiratory tract infection (10%). Ten (4%) subjects experienced serious adverse events, and 40 (17%) subjects discontinued because of an adverse event. Increases in ammonia levels were observed. No other clinically significant changes were observed in laboratory values, vital signs, rating scales, or electrocardiograms. Median 4-week migraine headache days decreased 75% between the first and the fourth months of the study (from 4.0 to 1.0) and remained at or below this level for the remainder of the study. Conclusions., In this long-term open-label study of adolescents with migraine, the safety and tolerability profile of divalproex sodium extended-release was consistent with findings from previous trials in adults, as well as 2 studies recently completed in adolescents. In general, divalproex sodium extended-release was well-tolerated in adolescents with migraine. [source] CYP2D6 polymorphism and clinical effect of the antidepressant venlafaxineJOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 5 2006M. E. E. Shams PhD Summary Background:, Venlafaxine (V) is a mixed serotonin and noradrenaline reuptake inhibitor used as a first-line treatment of depressive disorders. It is metabolized primarily by the highly polymorphic cytochrome P450 (CYP) enzyme CYP2D6 to yield a pharmacologically active metabolite, O -desmethylvenlafaxine (ODV), and to a lesser extent by CYP3A4, to yield N -desmethylvenlafaxine (NDV). Objectives:, The aim of this study was to assess whether the O-demethylation phenotype of V has an impact on the pharmacokinetics and clinical outcome. Method:, In 100 patients treated with V, serum concentrations of V, ODV and NDV and the ratios of concentrations ODV/V as a measure of O-demethylation were determined. Individuals exhibiting abnormally high or low metabolic ratios of ODV/V were selected for genotyping. Clinical effects were monitored by the Clinical Global Impressions Scale and side effects by the UKU (Udvalg for Kliniske Undersogelser Side Effect Rating Scale) rating scale. Results:, There was wide inter-individual variability in ODV/V ratios. The median ratio ODV/V was 1·8 and the 10th and 90th percentiles 0·3 and 5·2, respectively. Individuals with ODV/V ratios below 0·3 were all identified as poor metabolizers (PM), with the genotypes *6/*4 (n = 1), *5/*4 (n = 2) or *6/*6 (n = 1). Individuals with ratios above 5·2 were all ultra rapid metabolizers (UM, n = 6) due to gene duplications. Five individuals with intermediate metabolic activity (ODV/V, 1·1 ± 0·8) were heterozygotes with the CYP2D6*4 genotype, and one patient with an intermediate metabolic ratio of 4·8 had the genotype *4/2x*1. Clinical outcome measurements revealed that patients with ODV/V ratios below 0·3 had more side effects (P < 0·005) and reduced serum concentrations of sodium (P < 0·05) in comparison with other patients. Gastrointestinal side effects, notably nausea, vomiting and diarrhoea were the most common. Differences in therapeutic efficacy were not significant between the different phenotypes. Conclusion:, The O-demethylation phenotype of V depends strongly on the CYP2D6 genotype. A PM phenotype of CYP2D6 increases the risk of side effects. [source] Measurement of antipsychotic-induced side effects: Support for the validity of a self-report (LUNSERS) versus structured interview (UKU) approach to measurementHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 5 2003T. J. R. Lambert Abstract A self-report measure of antipsychotic side effects (LUNSERS) was compared with that of an established semi-structured interview (UKU side effect rating scale). The validity and the ability of the LUNSERS to determine false positives by use of an internal ,red herring' subscale were assessed. ,Red herring' items are those which do not directly relate to known antipsychotic side effects. In an open study, 29 patients with schizophrenia and schizoaffective disorder from inpatient and outpatient settings within an Australian metropolitan mental health service were assessed for antipsychotic-induced side effects using both the LUNSERS and UKU. The LUNSERS and UKU were similar in their overall assessment of antipsychotic side effects (total score correlation of 0.58) and were correlated on a wide array of individual side effect items. Correlations between total scores and individual items were higher for those patients scoring low on the LUNSERS ,red herring' items compared with both those with high ,red herring' scores and the sample as a whole. Several LUNSERS items were identified as potentially problematic, requiring further explanation or supplementation with direct questioning. The ,red herring' scale appears to enable detection of patients that may be over-reporting symptomatology. The LUNSERS is a valuable self-report measure of antipsychotic side effects, particularly in cases where red herring scores are low. Copyright © 2003 John Wiley & Sons, Ltd. [source] | ||||||||||
