  • Efficacy of Treatments for Patients with Obsessive-Compulsive Disorder: a Systematic Review
    REVIEW Efficacy of treatments for patients with obsessive-compulsive disorder: A systematic review Yun-Jung Choi, PhD, RN, PMHNP (Lecturer) Keywords Abstract Systematic review; obsessive-compulsive disorder; efficacy of medication.

An adequate drug trial involves administering an effective daily dose for a minimum of 8 weeks. An augmentation strategy proven effective for individuals refractory to monother- apy with SSRI treatment alone is the use of atypical antipsychotics (risperidone, olanzapine, and quetiapine). Implications for practice: Administration of fluvoxamine or sertraline to patients for an adequate duration is recommended as the first-line prescription for OCD, and augmentation therapy with risperidone, olanzapine, or quetiapine is recommended for refractory OCD.

An observational retrospective study including 102 adults with clonidine poisoning was conducted. 57 patients with relatively mild conditions were placed in the local emergency departments (EDs) for clinical observation, while the remaining 45 were transferred to the tertiary hospital for intensive treatment, of whom 9 were given supportive care only and 36 were given hemoperfusion (HP), as well as similar supportive treatment. The main symptoms of these cases were: sleepiness, dizziness, fatigue, headache, inarticulacy, tinnitus and dry mouth. Physical examination showed hypotension, bradycardia and shallow and slow breathing. Serum and urine clonidine concentrations were signicantly elevated24.4 ng/ml, 313.2 ng/ml, respectively. All cases slowly returned to their baseline state over 48 to 96 hours, which is co-related with the drawn of serum clonidine level.

  • Meta-Analysis of the Dose-Response Relationship of SSRI in Obsessive
    Molecular Psychiatry (2010) 15, 850–855 & 2010 Macmillan Publishers Limited All rights reserved 1359-4184/10 www.nature.com/mp ORIGINAL ARTICLE Meta-analysis of the dose-response relationship of SSRI in obsessive-compulsive disorder MH Bloch1, J McGuire1, A Landeros-Weisenberger1, JF Leckman1 and C Pittenger2 1Yale Child Study Center, Yale University School of Medicine, New Haven, CT, USA and 2Department of Psychiatry, Yale University School of Medicine, New Haven, CT, USA We sought to determine differences in efficacy and tolerability between different doses of selective serotonin reuptake inhibitors in the treatment of obsessive-compulsive disorder (OCD) using meta-analysis. We identified 9 studies involving 2268 subjects that were randomized, double-blind placebo-controlled clinical trials that compared multiple, fixed- doses of selective serotonin reuptake inhibitors (SSRIs) to each other and to placebo in the treatment of adults with OCD. Change in Y-BOCS score, proportion of treatment responders, and dropouts (all-cause and due to side-effects) were determined for each included study. Weighted mean difference was used to examine mean change in Y-BOCS score. Pooled absolute risk difference was used to examine dichotomous outcomes. Meta-analysis was performed using a fixed effects model in RevMan 4.2.8. We found that compared with either low or medium doses, higher doses of SSRIs were associated with improved treatment efficacy, using either Y-BOCS score or proportion of treatment responders as an outcome. Dose of SSRIs was not associated with the number of all-cause dropouts. Higher doses of SSRIs were associated with significantly higher proportion of dropouts due to side-effects.

  • A Synbiotic Mixture Augmented the Efficacy of Doxepin, Venlafaxine
    A synbiotic mixture augmented the efficacy of doxepin, venlafaxine, and fluvoxamine in mice model of depression Azadeh Mesripour1, Andiya Meshkati1, Valiolah Hajhashemi2 1Department of Pharmacology and Toxicology, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. 2‐ Isfahan Pharmaceutical Sciences Research Center, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. ABSTRACT Objective: Currently available antidepressant drugs have notable downsides; in addition to their side effects and slow onset of action their moderate efficacy in some individuals, may influence compliance. Previous literature has shown that probiotics may have antidepressant effects. Introducing complementary medicineproof in order to augment the efficacy of therapeutic doses of antidepressant drugs seems to be very important. Therefore the effect of adding a synbiotic cocktail in drinking water was assessed in mice model of despair following administrating three antidepressant drugs belonging to different classes. Methods: The marble burring test (MBT), and forced swimming test (FST) were used as animal model of obsessive behavior and despair. The synbiotic cocktail was administered in mice drinking water (6.25×106 CFU) for 14 days and the tests were performed on the days 7 and 14 thirty minutes after injecting the lowest dose of doxepin (1 mg/kg), venlafaxine (15 mg/kg), and fluvoxamine (15 mg/kg). Results: After 7 days of the synbiotic ingestion immobility time decreased in FST for doxepin (92 sec ± 5.5) and venlafaxine (17.3 sec ± 2.5) compared to their control group (drinking water) but fluvoxamine could decrease immobility time after 14 days of ingesting the synbiotic (70 sec ± 7.5).

  • Impact of Citalopram and Fluvoxamine on Platelet Response To
    S24_5 Impact of Citalopram and Fluvoxamine on Platelet Response to Clopidogrel, a Randomized, Double-blind, Crossover Trial Bruria Hirsh Racch1, Galia Spectre2, Ella Shai2, Amit Ritter3, David Varon2, Ronny Alcalai3 1School of Pharmacy, Hadassah Hebrew University Medical Center, Israel 2Coagulation Unit, Hematology, Hadassah Hebrew University Medical Center, Israel 3Heart Institute, Hadassah Hebrew University Medical Center, Israel Background: Selective serotonin reuptake inhibitors (SSRI) are widely used antidepressant agents. Studies have shown that use of SSRI in combination with aspirin or warfarin is associated with an increased risk bleeding, while little information is known about the interaction of SSRIs and clopidogrel. Fluvoxamine and citalopram are both SSRIs and while fluvoxamine is an inhibitor of CYP2C19 and thus might reduce the efficacy of clopidogrel, the effect of citalopram on liver metabolism is unknown. Aim: The aim was to assess the effect these two different SSRIs on platelet aggregation and on the laboratory response to clopidogrel. Methods: A randomized, double-blind, crossover study in 15 healthy volunteers comparing the antiplatelet effect of clopidogrel with and without fluvoxamine or citalopram .The response to clopidogrel was assessed by Light Transmittance Aggregometry with10µmol/L ADP and by vasodilator-stimulated phosphoprotein (VASP) phosphorylation, a measure of P2Y12 receptor reactivity. Results: Mean baseline platelet aggregation was 80.1%±3.4 and reduced to 23.5% after treatment with clopidogrel. Both fluvoxamine and citalopram had modest effect on platelet reactivity (65.8%±6.4, p=0.06 vs. baseline and 67.3%±6.3, p=0.07 vs. baseline respectively). Laboratory response to clopidogrel was significantly better in the presence of citalopram as compared to fluvoxamine both in aggregometry (23.4%±3 vs.

  • Uremic Toxins and Blood Purification: a Review of Current Evidence and Future Perspectives
    toxins Review Uremic Toxins and Blood Purification: A Review of Current Evidence and Future Perspectives Stefania Magnani * and Mauro Atti Aferetica S.r.l, Via Spartaco 10, 40138 Bologna (BO), Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-0535-640261 Abstract: Accumulation of uremic toxins represents one of the major contributors to the rapid progression of chronic kidney disease (CKD), especially in patients with end-stage renal disease that are undergoing dialysis treatment. In particular, protein-bound uremic toxins (PBUTs) seem to have an important key pathophysiologic role in CKD, inducing various cardiovascular complications. The removal of uremic toxins from the blood with dialytic techniques represents a proved approach to limit the CKD-related complications. However, conventional dialysis mainly focuses on the removal of water-soluble compounds of low and middle molecular weight, whereas PBTUs are strongly protein-bound, thus not efficiently eliminated. Therefore, over the years, dialysis techniques have been adapted by improving membranes structures or using combined strategies to maximize PBTUs removal and eventually prevent CKD-related complications. Recent findings showed that adsorption-based extracorporeal techniques, in addition to conventional dialysis treatment, may effectively adsorb a significant amount of PBTUs during the course of the sessions. This review is focused on the analysis of the current state of the art for blood purification strategies in order to highlight their potentialities and limits and identify the most feasible solution to improve toxins removal effectiveness, exploring possible future strategies and applications, such as the study of a synergic approach by reducing PBTUs production and increasing their blood clearance.
