Folic acid efficacy as an alternative drug added to sodium valproate in the treatment of acute phase of mania in bipolar disorder: a double-blind randomized controlled trial

ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009
A. H. Behzadi
Objective:, The purpose of this study was to evaluate the efficacy of adding folic acid to sodium valproate in the acute phase of mania. Method:, Following a double-blind randomized controlled trial, 88 clinically manic patients with diagnosis of type I bipolar disorder (BID) were divided randomly into two groups (case and control). The case group was treated with folic acid and sodium valproate and the control group with sodium valproate and placebo. The severity of mania was assessed using the Young Mania Rating Scale (YMRS) at the beginning and end of the first, second and third weeks of the study. Results:, The case group's mean manic YMRS measurements (SD) before the initiation of therapy and in the first, second and third weeks of treatment were 34.0 ± 7.7, 26.7 ± 2.1, 18.1 ± 2.1 and 7.1 ± 0.9 respectively. The control group's measurements were 34.7 ± 3.8, 27.3 ± 2.3, 20.7 ± 2.5 and 10.1 ± 1.1. There was a statistically significant difference in YMRS scaling results between the case and control groups after 3 weeks of treatment (7.1 ± 0.9 vs. 10.1 ± 1.1, P = 0.005). Conclusion:, Based on our findings, folic acid seems to be an effective adjuvant to sodium valproate in the treatment of the acute phase of mania in patients with bipolar disorder. [source]


Olanzapine monotherapy for acute depression in patients with bipolar I or II disorder: results of an 8-week open label trial

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 1 2010
William V. Bobo
Abstract We evaluated the efficacy, tolerability, and safety of olanzapine monotherapy in 20 adult patients with bipolar I or II disorder, depressed phase. Patients received open-label olanzapine monotherapy (mean modal dose, 15,mg/day) for 8 weeks. Assessments of psychopathology (Montgomery,Asberg Depression Rating Scale [MADRS], Quick Inventory of Depressive Symptomatology [QIDS-SR-16], Young Mania Rating Scale [YMRS]), clinical global state (Clinical Global Impressions [CGI] scale), and safety/tolerability were performed at baseline, and at 1, 2, 4, 6, and 8 weeks. Seventeen patients (85.0%) completed the study. Improvement in MADRS total scores was observed after the first week of treatment, and at all remaining follow-up time points (p,,,0.005). Parallel improvement in QIDS-SR-16 (p,<,0.001) and CGI-Severity (p,<,0.001) was observed between baseline and study endpoint. Nine (45%) subjects achieved positive treatment response, eight of whom (40%) also achieved symptom remission. There were significant increases in weight (+3.2,kg, p,=,0.001) and body mass index (+1.1,kg/m2, p,=,0.001), but not fasting glucose or lipids, with the exception of reduced triglyceride levels in the overall sample, and reduced HDL cholesterol in females. Olanzapine may be an effective, well-tolerated option for treating acute non-psychotic depression across a variety of bipolar disorder subtypes. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Development of the Bipolar Inventory of Symptoms Scale: concurrent validity, discriminant validity and retest reliability

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 4 2008
Jodi M. Gonzalez
Abstract Scales used in studies of bipolar disorder have generally been standardized with major depressive or hospitalized manic patients. A clinician rated scale based on a semi-structured interview for persons with bipolar disorder, with comprehensive coverage of bipolar symptomatology, is needed. We report concurrent, divergent and convergent psychometric reliability, discriminant validity and relationship to a measure of overall function for a new psychometric rating instrument. A primarily outpatient sample of 224 subjects was assessed using the Bipolar Inventory of Symptoms Scale (BISS). The BISS total score and depression and mania subscales were compared to the Young Mania Rating Scale (YMRS), the Montgomery Asberg Depression Rating Scale (MADRS) and the Global Assessment of Functioning Scale (GAF). Clinical mood states were also compared using the BISS. The BISS scores demonstrated good concurrent validity, with estimates (Pearson correlations) ranging from 0.74 to 0.94 for YMRS and MADRS and test,retest reliability from 0.95 to 0.98. BISS concurrent validity with the GAF was significant for four clinical states, but not mixed states. The BISS discriminated primary bipolar mood states as well as subjects recovered for eight weeks compared to healthy controls. In conclusion, the BISS is a reliable and valid instrument broadly applicable in clinical research to assess the comprehensive domains of bipolar disorder. Future directions include factor analysis and sensitivity to change from treatment studies. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Comparing the psychometric properties of multiple teacher report instruments as predictors of bipolar disorder in children and adolescents

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 4 2008
Eric A. Youngstrom
Abstract The psychometric properties of four teacher report measures and their utility for accurate diagnosis of pediatric bipolar spectrum disorders (BPSDs) were examined. Participants were 191 youth (65% male; 62% African-American; 23% diagnosed with a BPSD), age 5,18 (M=10.16, SD=3.27) years, 70% recruited from a community mental health center and 30% recruited from a mood disorders clinic. Teachers "who knew the child best" were asked to complete the Achenbach Teacher Report Form (TRF) as well as teacher versions of the General Behavior Inventory (T-GBI), the Child Mania Rating Scale (CMRS-T), and the Young Mania Rating Scale (T-YMRS). Teacher response rates and missing data varied significantly depending on the age of the child. Exploratory factor analysis identified stable and interpretable factors; however, receiver operating characteristic (ROC) and logistic regression analyses showed that teacher report measures were not able to discriminate BPSD cases from non-BPSD cases, or from attention deficit hyperactivity disorder (ADHD) cases. Teacher report appears to be insufficiently specific or sensitive to BPSD for clinical diagnostic use, although teacher scales might have research utility. © 2008 Wiley Periodicals, Inc.

Pavuluri MN, Henry DB, Findling RL, Parnes S, Carbray JA, Mohammed T, Janicak PG, Sweeney JA. Double-blind randomized trial of risperidone versus divalproex in pediatric bipolar disorder. Bipolar Disord 2010: 12: 593,605. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective:, To determine the relative effects of risperidone and divalproex in pediatric mania. Methods:, This is a double-blind, randomized, outpatient clinical trial with 66 children and adolescents (mean age = 10.9 ± 3.3 years; age range = 8,18 years) with mania who were randomly assigned to either risperidone (0.5,2 mg/day, n = 33) or divalproex (60,120 ,g/mL, n = 33) for a six-week period. Measures included the Young Mania Rating Scale (YMRS) and Child Depression Rating Scale-Revised (CDRS-R). Results:, Mixed-effects regression models, with interaction between time and the active drug as predictors, found that the risperidone group had more rapid improvement than the divalproex group (p < 0.05), although final scores did not differ significantly between groups. Mixed models using only those subjects who completed the six-week study found similar results. The response rate on YMRS was 78.1% for risperidone and 45.5% for divalproex (p < 0.01). The remission rate for risperidone was 62.5%, compared with 33.3% for divalproex (p < 0.05). Improvement on the CDRS-R was significantly higher for the risperidone group relative to the divalproex group (p < 0.05). There were no significant differences between groups in safety, but subject retention was significantly higher at study endpoint in the risperidone group (p < 0.01). Dropout rate was 24% in the risperidone group and 48% in the divalproex group, with increased irritability being the most common reason for dropout in the latter. There was no significant weight gain in either group. Conclusion:, Results suggest that risperidone was associated with more rapid improvement and greater reduction in manic symptoms compared to divalproex. Although the results suggest that both drugs are safe, risperidone's lower attrition rate and lower rate of adverse events may suggest better toleration. Clinical trials with larger samples are required to confirm these preliminary findings. [source]

A randomized, placebo- and active-controlled study of paliperidone extended release for the treatment of acute manic and mixed episodes of bipolar I disorder. Bipolar Disord 2010: 12: 230,243. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, To evaluate the antimanic efficacy and safety of paliperidone extended-release (ER) tablets in patients with bipolar I disorder. Methods:, This study included a 3-week, double-blind, acute treatment phase (paliperidone ER versus placebo, with quetiapine as control), and a 9-week, double-blind, maintenance phase (paliperidone ER versus quetiapine). Patients [n = 493; Young Mania Rating Scale (YMRS) score , 20] were randomized (2:2:1) to flexibly dosed paliperidone ER (3,12 mg/day), quetiapine (400,800 mg/day), or placebo for the acute treatment phase. During the maintenance phase, patients assigned to placebo were switched to paliperidone ER but not included in analysis of efficacy. Results:, Paliperidone ER was superior to placebo at the 3-week endpoint {primary outcome; least-squares mean difference in change from baseline in YMRS scores [95% confidence interval (CI)]: ,5.5 (,7.57; ,3.35); p < 0.001} and noninferior to quetiapine at the 12-week endpoint [least-squares mean difference (95% CI): 1.7 (,0.47; 3.96)]. The median mode dose during the 12-week treatment period was 9 mg for paliperidone ER and 600 mg for quetiapine. The most common (, 10%) treatment-emergent adverse events during the 12-week period were: headache (16%), somnolence (10%), and akathisia (10%) for paliperidone ER; somnolence (21%), sedation and dry mouth (17% each), headache (14%), and dizziness (13%) for quetiapine. Body weight increase , 7% from baseline to 12-week endpoint was 8% with paliperidone ER and 17% with quetiapine. A higher percentage of paliperidone ER (13.9%) versus quetiapine patients (7.5%) ,switched to depression' at the12-week endpoint. Conclusions:, Paliperidone ER (3,12 mg/day) was efficacious and tolerable in the treatment of acute mania. [source]

Bipolar Disord 2010: 12: 142,154. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, This clinical trial evaluated whether supplementation with flax oil, containing the omega-3 fatty acid ,-linolenic acid (,-LNA), safely reduced symptom severity in youth with bipolar disorder. Methods:, Children and adolescents aged 6,17 years with symptomatic bipolar I or bipolar II disorder (n = 51), manic, hypomanic, mixed, or depressed, were randomized to either flax oil capsules containing 550 mg ,-LNA per 1 gram or an olive oil placebo adjunctively or as monotherapy. Doses were titrated to 12 capsules per day as tolerated over 16 weeks. Primary outcomes included changes in the Young Mania Rating Scale, Child Depression Rating Scale-Revised, and Clinical Global Impressions-Bipolar ratings using Kaplan-Meier survival analyses. Results:, There were no significant differences in primary outcome measures when compared by treatment assignment. However, clinician-rated Global Symptom Severity was negatively correlated with final serum omega-3 fatty acid compositions: %,-LNA (r = ,0.45, p < 0.007), % eicosapentaenoic acid (EPA) (r = ,0.47, p < 0.005); and positively correlated with final arachidonic acid (AA) (r = 0.36, p < 0.05) and docosapentaenoic acid (DPA) n-6 (r = 0.48, p < 0.004). The mean duration of treatment for ,-LNA was 11.8 weeks versus 8 weeks for placebo; however, the longer treatment duration for ,-LNA was not significant after controlling for baseline variables. Subjects discontinued the study for continued depressive symptoms. Conclusions:, Studies of essential fatty acid supplementation are feasible and well tolerated in the pediatric population. Although flax oil may decrease severity of illness in children and adolescents with bipolar disorder who have meaningful increases in serum EPA percent levels and/or decreased AA and DPA n-6 levels, individual variations in conversion of ,-LNA to EPA and docosahexaenoic acid as well as dosing burden favor the use of fish oil both for clinical trials and clinical practice. Additionally, future research should focus on adherence and analysis of outcome based on changes in essential fatty acid tissue compositions, as opposed to group randomization alone. [source]


Asenapine versus olanzapine in acute mania: a double-blind extension study

BIPOLAR DISORDERS, Issue 8 2009
Roger S McIntyre
Objective:, To assess the efficacy and tolerability of asenapine versus olanzapine in the extended treatment of bipolar mania. Methods:, Patients with bipolar I disorder experiencing acute manic or mixed episodes who completed either of two 3-week, double-blind trials with asenapine 5 or 10 mg twice daily, olanzapine 5 to 20 mg once daily, or placebo were eligible for this 9-week, double-blind extension study. Patients receiving active medication in the 3-week trials continued the same regimen; those who had received placebo were blindly switched to asenapine but were assessed for safety outcomes only. The primary efficacy measure was the change from baseline to day 84 on the Young Mania Rating Scale (YMRS) total score in the per-protocol population. Results on the primary efficacy outcome were used to determine the noninferiority of asenapine versus olanzapine. Results:, A total of 504 patients (placebo/asenapine, n = 94; asenapine, n = 181; olanzapine, n = 229) were enrolled in the extension study. At day 84, the mean (SD) change from baseline in YMRS total score was ,24.4 (8.7) for asenapine and ,23.9 (7.9) for olanzapine. Prespecified statistical analysis for noninferiority indicated no significant difference between asenapine and olanzapine. The overall incidence of treatment-emergent adverse events was similar across treatment groups (77% placebo/asenapine, 77% asenapine, 78% olanzapine). Clinically significant weight gain occurred in 10%, 19%, and 31% of the placebo/asenapine, asenapine, and olanzapine groups, respectively. Conclusions:, Asenapine was efficacious, showed noninferiority to olanzapine, and was well tolerated in the extended treatment of patients experiencing manic symptoms associated with bipolar I disorder.

Risperidone for the treatment of acute mania in children and adolescents with bipolar disorder: a randomized, double-blind, placebo-controlled study

BIPOLAR DISORDERS, Issue 7 2009
Magali Haas
Objectives:, To evaluate the efficacy, safety, and tolerability of risperidone monotherapy for the treatment of an acute mixed or manic episode in children and adolescents with bipolar I disorder. Methods:, This randomized, placebo-controlled, double-blind, 3-arm study (N = 169) included children and adolescents (ages 10,17 years) with a DSM-IV diagnosis of bipolar I disorder, experiencing a manic or mixed episode. Study participants were randomized to placebo (n = 58), risperidone 0.5,2.5 mg/day (n = 50), or risperidone 3,6 mg/day (n = 61) for 3 weeks. The primary efficacy measure was change in Young Mania Rating Scale (YMRS) total score from baseline to end point. Safety assessments included adverse event (AE) monitoring and scores on extrapyramidal symptom rating scales. Results:, Improvement in mean YMRS total score was significantly greater in risperidone-treated subjects than in placebo-treated subjects [mean change (SD) ,9.1 (11.0) for placebo; ,18.5 (9.7) for risperidone 0.5,2.5 mg (p < 0.001); ,16.5 (10.3) for risperidone 3,6 mg (p < 0.001)]. The most common risperidone-associated AEs were somnolence, headache, and fatigue. Mean (SD) weight gain was 0.7 (1.9) kg, 1.9 (1.7) kg, and 1.4 (2.4) kg in the placebo, risperidone 0.5,2.5 mg, and risperidone 3,6 mg groups, respectively, during this 3-week study. Conclusions:, At daily doses of 0.5,2.5 mg and 3,6 mg, risperidone was effective and well tolerated in children and adolescents experiencing acute manic or mixed episodes of bipolar I disorder. Results indicate that risperidone 0.5,2.5 mg has a better benefit,risk profile than risperidone 3,6 mg. [source]


A double-blind, placebo-controlled pilot study of quetiapine for depressed adolescents with bipolar disorder

BIPOLAR DISORDERS, Issue 5 2009
Melissa P DelBello
Objective:, To conduct a pilot study comparing the effects of quetiapine and placebo for the treatment of depressive episodes in adolescents with bipolar I disorder. Method:, Thirty-two adolescents (ages 12,18 years) with a depressive episode associated with bipolar I disorder were randomized to eight weeks of double-blind treatment with quetiapine, 300,600 mg/day, or placebo. This two-site study was conducted from March 2006 through August 2007. The primary efficacy measure was change in Children's Depression Rating Scale,Revised Version (CDRS-R) scores from baseline to endpoint. Secondary efficacy measures included change in CDRS-R scores over the eight-week study period (PROC MIXED), changes from baseline to endpoint in Hamilton Anxiety Rating Scale (HAM-A), Young Mania Rating Scale (YMRS), and Clinical Global Impression,Bipolar Version Severity (CGI-BP-S) scores, as well as response and remission rates. Safety and tolerability were assessed weekly. Results:, There was no statistically significant treatment group difference in change in CDRS-R scores from baseline to endpoint (p = 0.89, effect size =,0.05, 95% confidence interval: ,0.77,0.68), nor in the average rate of change over the eight weeks of the study (p = 0.95). Additionally, there were no statistically significant differences in response (placebo =67% versus quetiapine = 71%) or remission (placebo = 40% versus quetiapine = 35%) rates, or change in HAM-A, YMRS, or CGI-BP-S scores (all p > 0.7) between treatment groups. Dizziness was more commonly reported in the quetiapine (41%) than in the placebo (7%) group (Fisher's exact test, p = 0.04). Conclusions:, The results suggest that quetiapine monotherapy is no more effective than placebo for the treatment of depression in adolescents with bipolar disorder. However, limitations of the study, including the high placebo response rate, may have contributed to our findings and should be considered in the design of future investigations of pharmacological interventions for this population.

Effects of stimulus intensity on the efficacy and safety of twice-weekly, bilateral electroconvulsive therapy (ECT) combined with antipsychotics in acute mania: a randomised controlled trial

BIPOLAR DISORDERS, Issue 2 2009
Titus SP Mohan
Objectives:, To examine differences in speed of improvement and remission in people with mania undergoing bilateral, brief-pulse, twice-weekly electroconvulsive therapy (ECT) at stimulus intensities administered just above and 2.5 times their individually titrated seizure threshold. Methods:, Consecutive, eligible subjects with mania, prescribed ECT, were randomised to receive treatments at stimulus doses either just above or 2.5 times their individually titrated seizure thresholds. Main outcomes were the speed of improvement and remission as measured by the Young Mania Rating Scale (YMRS) and the Clinical Global Impressions,Improvement scale (CGI-I) and cognitive side effects assessed by the Mini-Mental State Exam, the Wechsler Memory Scale, and a scale for autobiographical memory. Results:, A total of 24/26 subjects (92.3%) given threshold ECT and 22/24 subjects (91.7%) given suprathreshold ECT were significantly improved [CGI = 2; odds ratio (OR) = 1.1, 95% confidence interval (CI): 0.1,8.4; p = 1.0] at the end of ECT. A total of 88% of the sample had remitted [YMRS < 10; threshold 23/26 (88.5%) versus suprathreshold 21/24 (87.5%)], with no significant differences between interventions (OR = 1.1, 95% CI: 0.2, 6.0; p = 1.0). The interventions did not differ significantly in the time or number of ECT treatments required for improvement or remission. Both interventions were equally safe. Conclusions:, Bilateral, twice-weekly ECT delivered at stimulus intensities just above individually titrated seizure threshold was as effective and safe as ECT administered at stimulus intensities 2.5 times seizure threshold in rapidly resolving the symptoms of acute mania.

Quetiapine for the treatment of bipolar mania in older adults

BIPOLAR DISORDERS, Issue 6 2008
Martha Sajatovic
Objectives:, A post hoc analysis of pooled data from two quetiapine monotherapy clinical trials was conducted to evaluate the efficacy and tolerability of quetiapine therapy (twice daily, 400,800 mg/day) among bipolar manic adults aged 55 years and older. The primary efficacy endpoint was the change from baseline in Young Mania Rating Scale (YMRS) total score at Day 21. A secondary endpoint was change from baseline in YMRS score at Day 84. Methods:, A total of 407 patients made up the safety population, consisting of 59 older adults (aged ,55 years) and 348 younger adults. A total of 403 patients made up the efficacy population, consisting of 59 older adults and 344 younger adults. Efficacy outcomes were analyzed using covariance models (ANCOVA); descriptive statistics are presented for safety outcomes. Results:, Both older and younger individuals treated with quetiapine had significant improvement from baseline on YMRS scores compared with placebo-treated patients. The older adult group demonstrated a sustained reduction in YMRS score compared with placebo that was apparent by Day 4 of treatment. For the quetiapine treatment groups, the most common adverse effects (at a frequency ,10%) were dry mouth, somnolence, postural hypotension, insomnia, weight gain, and dizziness in older adults, and dry mouth, somnolence, and insomnia in younger adults. For the placebo treatment groups, insomnia was the most common adverse event in both older and younger adults. Conclusions:, This secondary analysis suggests that quetiapine represents a potentially useful treatment option among older adults with bipolar I mania. Studies with a primary focus of geriatric bipolar mania, and including larger patient numbers, are needed to confirm these findings. [source]


Initiation of stimulant and antidepressant medication and clinical presentation in juvenile bipolar I disorder

BIPOLAR DISORDERS, Issue 2 2008
Maria E Pagano
Objectives:, The primary purpose of this study was to examine the extent to which the initiation of stimulant and antidepressant medication was associated with the subsequent onset of juvenile bipolar I disorder (BP I). Another aim was to investigate differences in clinical presentation between youths prescribed stimulant or antidepressant medication before and after the onset of juvenile BP I disorder. Methods:, Youths between the ages of 5 and 17 years meeting full, unmodified DSM-IV diagnostic symptom criteria for BP were included in this study. Data regarding the age of onset of BP I, psychiatric comorbidities, and current symptoms of mania and depression were obtained. Medication history was recorded as part of the assessment interview with parents and youths. Results:, Of the 245 youths with BP I, 65% (n = 160) were treated with stimulant medication; 32% (56/173) were treated after the onset of BP I, and 19% (32/173) were treated before the onset of BP I. Forty-six percent (113/245) were treated with antidepressant medication; 33% (67/206) were treated after the onset of BP I, and 3% (7/206) were treated before the onset of BP I. Patients who were treated with stimulants after the onset of BP I were significantly more likely to be younger (p < 0.0001). Patients who were treated with antidepressants before the onset of BP I were significantly more likely to be older and to have lower levels of mania on the Young Mania Rating Scale at assessment (p < 0.01). Conclusions:, Data from this retrospective case series do not support the association between initial stimulant or antidepressant use and the onset of BP I or presenting symptoms of depression or manic symptoms.

Rapid tryptophan depletion as a treatment for acute mania: a double-blind, pilot-controlled study

BIPOLAR DISORDERS, Issue 8 2007
Julia Applebaum
Objectives:, Rapid reduction of up to 80% in plasma tryptophan level can be accomplished by administering an oral tryptophan-free amino acid solution, which induces hepatic protein synthesis and thereby depletes available plasma tryptophan. Rapid tryptophan depletion (RTD) has been shown to induce transient depressive symptoms in patients with remitted major depression. The effect of RTD in acutely manic patients has not been studied. Methods:, We carried out a double-blind, placebo-controlled pilot study of RTD in acutely manic patients. Patients were randomized to the treatment groups. Sodium valproate treatment was started at a dose of 1000 mg/day and continued throughout the 7-day study. On days 1-7, patients received a daily tryptophan-free amino acid drink or a placebo drink. The tryptophan-free amino acid drink contained a mix of amino acids without tryptophan. The placebo drink contained the additives and constituents of the real mixture to provide identical flavor and texture without the amino acids. Ratings were administered at baseline and then repeated on days 3, 5, and 7. All ratings were carried out by an experienced rater who was blind to the group assignment of patients. Results:, A total of 23 patients entered the study and 17 completed the 7-day treatment protocol. The patients who received the amino acid drink showed greater improvement in mania ratings. The differences in Young Mania Rating Scale (YMRS) and Clinical Global Impression (GCI) scores were significant. However, the intolerance rate was high (23%) and the findings in this pilot study are based only on results from those patients who were able to tolerate the drink. Conclusions:, Rapid tryptophan depletion may have an antimanic effect. [source]


A prospective open-label treatment trial of ziprasidone monotherapy in children and adolescents with bipolar disorder

BIPOLAR DISORDERS, Issue 8 2007
Joseph Biederman
Objective:, To assess the effectiveness and tolerability of ziprasidone for treating pediatric mania. Methods:, This was an eight-week, open-label, prospective study of ziprasidone monotherapy (57.3 ± 33.9 mg/day) in 21 bipolar youth [manic, mixed, or bipolar not otherwise specified (NOS); 6,17 years old]. Assessments included the Young Mania Rating Scale (YMRS), Clinical Global Impressions-Improvement scale (CGI-I), and Brief Psychiatric Rating Scale (BPRS). Adverse events were assessed through spontaneous self-reports, vital signs, weight monitoring, and laboratory analysis. Results:, Fourteen of the 21 youth (67%) completed the study. Ziprasidone treatment was associated with clinically and statistically significant improvement in mean YMRS scores (,10.8 ± 8.4, p < 0.0001) and 57% had a CGI-I ,2 at endpoint. Ziprasidone was well tolerated with no statistically significant increase in body weight (0.6 ± 0.4 kg, p = 0.2) or QTc interval (,3.7 ± 4.7, p = 0.5). Conclusions:, Open-label ziprasidone treatment was associated with a significant short-term improvement of symptoms of pediatric bipolar disorder. Future placebo-controlled, double-blind studies are warranted. [source]


Efficacy of a protein kinase C inhibitor (tamoxifen) in the treatment of acute mania: a pilot study

BIPOLAR DISORDERS, Issue 6 2007
Carlos A Zarate Jr
Objectives:, Considerable preclinical biochemical and behavioral data suggest that protein kinase C inhibition would bring about antimanic effects. Notably, the structurally highly dissimilar antimanic agents lithium and valproate, when administered in therapeutically relevant paradigms, attenuate protein kinase C inhibition function. There is currently only one relatively selective protein kinase C inhibitor that crosses the blood,brain barrier available for human use , tamoxifen. Our group recently conducted a single-blind study with tamoxifen in acute mania and found that it significantly decreased manic symptoms within a short period of time (3,7 days). In this study, we investigated whether antimanic effects can be achieved with a protein kinase C inhibitor in subjects with mania. Methods:, In a double-blind, placebo-controlled study, 16 subjects with bipolar disorder, manic or mixed, with or without psychotic features, were randomly assigned to receive tamoxifen (20,140 mg/day; n = 8) or placebo (n = 8) for three weeks. Primary efficacy was assessed by the Young Mania Rating Scale. Results:, Subjects on tamoxifen showed significant improvement in mania compared to placebo as early as five days, an effect that remained significant throughout the three-week trial. The effect size for the drug difference was very large (d = 1.08, 95% confidence interval 0.45,1.71) after three weeks (p = 0.001). At study endpoint, response rates were 63% for tamoxifen and 13% for placebo (p = 0.12). Conclusions:, Antimanic effects resulted from a protein kinase C inhibitor; onset occurred within five days. Large, controlled studies with selective protein kinase C inhibitors in acute mania are warranted. [source]


Effects of lamotrigine in patients with bipolar disorder and alcohol dependence

BIPOLAR DISORDERS, Issue 3 2006
Gabriel Rubio
Background:, Bipolar disorder is significantly associated with alcohol use disorders. Anticonvulsant drugs are used in the treatment of bipolar disorder and they have also been used to treat alcohol dependence. The purpose of the present study was to evaluate tolerance and safety of lamotrigine in a dual-diagnosis population presenting bipolar disorder and alcohol dependence. Open-label lamotrigine was examined in 28 outpatients with DSM-IV bipolar disorder and alcohol dependence. Lamotrigine was added to existing medication regimens. Method:, Lamotrigine was started at a dose of 25 mg/day and titrated to a maximum dose of 300 mg/day. Subjects received a baseline evaluation which included a Structured Clinical Interview for DSM-IV (SCID) and weekly assessments for 12 weeks with the Hamilton Rating Scale for Depression (HAM-D), Young Mania Rating Scale (YMRS), Brief Psychiatric Rating Scale (BPRS), Severity of Alcohol Dependence Scale (SADS), a Visual Analogue Scale for Craving severity (VASC), and alcohol consumption. The concentration of carbohydrate-deficient transferrin (CDT) was used as an indirect measure of alcohol consumption. The sample consisted of 18 men and 10 women diagnosed with alcohol dependence and bipolar disorder I (n = 21) or bipolar disorder II (n = 7), with a mean age of 36.5 ± 7.7 years. Results:, Significant improvement was observed in HAM-D, YMRS, and BPRS scores (p < 0.01). Craving and CDT also significantly decreased (p < 0.001). Lamotrigine was well tolerated with no dropout subjects due to adverse events. Conclusion:, Lamotrigine is safe and well tolerated in this sample and associated with improvement in mood, alcohol craving and alcohol consumption. A placebo-controlled study would be of interest.

Topiramate monotherapy in the management of acute mania: results of four double-blind placebo-controlled trials

BIPOLAR DISORDERS, Issue 1 2006
Stuart F Kushner
Objective:, To evaluate the efficacy and tolerability of topiramate monotherapy in adults with acute manic or mixed episodes of bipolar I disorder. Methods:, In four trials, adults hospitalized with acute mania, a diagnosis of bipolar I disorder, history of ,1 previous manic or mixed episodes, and ,20 Young Mania Rating Scale (YMRS) score were randomized to double-blind treatment with topiramate (target doses: 200, 400, or 600 mg/day) or placebo; two trials included an active comparator (lithium, 1500 mg/day). The core study duration in all trials was 3 weeks; three trials also had 9-week double-blind extensions. The primary efficacy variable was mean change from baseline in YMRS in the core 3-week study. Results:, Changes in YMRS score during 3 weeks were not significantly different for topiramate versus placebo (mean YMRS reductions, ,5.1 to ,8.4). Mean YMRS reductions in lithium-treated groups were significantly greater (p , 0.001 versus placebo and topiramate). A similar pattern was observed after 12 weeks of double-blind treatment in studies with double-blind extensions. Paresthesia, appetite decrease, dry mouth, and weight loss were more frequently associated with topiramate than with placebo. Conclusions:, These studies do not support the efficacy of topiramate as monotherapy in acute mania or mixed episodes in adults with bipolar I disorder. Topiramate was not associated with mood destabilization measured as mania exacerbation or treatment-emergent depression. Lithium was confirmed as an effective therapy in this population. [source]


Dark therapy for mania: a pilot study

BIPOLAR DISORDERS, Issue 1 2005
Barbara Barbini
Background:, Recent findings suggest that extended bed rest and darkness could stabilize mood swings in rapid cycling bipolar patients. Method:, We exposed 16 bipolar inpatients affected by a manic episode to a regimen of 14 h of enforced darkness from 6 p.m. to 8 a.m. each night for three consecutive days [dark therapy (DT)]. Pattern of mood changes were recorded with the Young Mania Rating Scale (YMRS) and compared with a control group of 16 inpatients matched for age, sex, age at onset, number of previous illness episodes and duration of current episode, and were treated with therapy as usual (TAU). Results:, Adding DT to TAU resulted in a significantly faster decrease of YMRS scores when patients were treated within 2 weeks from the onset of the current manic episode. When duration of current episode was longer, DT had no effect. Follow-up confirmed that good responders needed a lower dose of antimanic drugs and were discharged earlier from the hospital. Conclusions:, Chronobiological interventions and control of environmental stimuli can be a useful add-on for the treatment of acute mania in a hospital setting. [source]


Statistical methods for longitudinal research on bipolar disorders

BIPOLAR DISORDERS, Issue 3 2003
John Hennen
Objectives: Outcomes research in bipolar disorders, because of complex clinical variation over-time, offers demanding research design and statistical challenges. Longitudinal studies involving relatively large samples, with outcome measures obtained repeatedly over-time, are required. In this report, statistical methods appropriate for such research are reviewed. Methods: Analytic methods appropriate for repeated measures data include: (i) endpoint analysis; (ii) endpoint analysis with last observation carried forward; (iii) summary statistic methods yielding one summary measure per subject; (iv) random effects and generalized estimating equation (GEE) regression modeling methods; and (v) time-to-event survival analyses. Results: Use and limitations of these several methods are illustrated within a randomly selected (33%) subset of data obtained in two recently completed randomized, double blind studies on acute mania. Outcome measures obtained repeatedly over 3 or 4 weeks of blinded treatment in active drug and placebo sub-groups included change-from-baseline Young Mania Rating Scale (YMRS) scores (continuous measure) and achievement of a clinical response criterion (50% YMRS reduction). Four of the methods reviewed are especially suitable for use with these repeated measures data: (i) the summary statistic method; (ii) random/mixed effects modeling; (iii) GEE regression modeling; and (iv) survival analysis. Conclusions: Outcome studies in bipolar illness ideally should be longitudinal in orientation, obtain outcomes data frequently over extended times, and employ large study samples. Missing data problems can be expected, and data analytic methods must accommodate missingness. [source]


Persistent attentional dysfunction in remitted bipolar disorder

BIPOLAR DISORDERS, Issue 2 2001
Kelly E Wilder-Willis
Objectives: Although previous research has shown that attentional dysfunction is common during acute mood episodes in individuals with bipolar disorder (BPD), few studies have examined whether attentional deficits are evident during periods of symptom stability. The goal of this study was to determine whether clinically stable individuals with BPD would have attentional disturbances relative to healthy subjects. Methods: Fourteen patients with BPD and 12 healthy comparison subjects participated in the study, and were administered the Degraded Stimulus Continuous Performance Test (DSCPT), Digit Span Distractibility Test (DSDT) and Grooved Pegboard Test (GPT). Psychiatric symptoms were assessed with the Young Mania Rating Scale and the Scale for the Assessment of Positive Symptoms. Medication side effects were measured with the Simpson Rating Scale. Results: The patient group responded significantly more slowly than the control group on the DSCPT (z=,2.52, p=0.01) and the GPT (z=,3.37, p=0.001). There was a trend towards the BPD patients demonstrating impaired perceptual sensitivity on the DSCPT (z=1.68, p=0.09). The two groups did not differ on the DSDT (z=,1.06, p=0.3). Poor performance on the GPT and DSCPT target reaction time were not associated with symptom ratings or medications. Conclusion: The findings suggest that impairments in fine motor skills and reaction time may be present in clinically stable patients with BPD, even after accounting for psychiatric symptoms and medication effects. Performance decrements on attentional tasks may be in part reflective of motor impairments in patients with BPD. [source]


The validity and internal structure of the Bipolar Depression Rating Scale: data from a clinical trial of N-acetylcysteine as adjunctive therapy in bipolar disorder

Berk M, Dodd S, Dean OM, Kohlmann K, Berk L, Malhi GS. The validity and internal structure of the Bipolar Depression Rating Scale: data from a clinical trial of N-acetylcysteine as adjunctive therapy in bipolar disorder. Background: The phenomenology of unipolar and bipolar disorders differ in a number of ways, such as the presence of mixed states and atypical features. Conventional depression rating instruments are designed to capture the characteristics of unipolar depression and have limitations in capturing the breadth of bipolar disorder. Method: The Bipolar Depression Rating Scale (BDRS) was administered together with the Montgomery Asberg Rating Scale (MADRS) and Young Mania Rating Scale (YMRS) in a double-blind randomised placebo-controlled clinical trial of N-acetyl cysteine for bipolar disorder (N = 75). Results: A factor analysis showed a two-factor solution: depression and mixed symptom clusters. The BDRS has strong internal consistency (Cronbach's alpha = 0.917), the depression cluster showed robust correlation with the MADRS (r = 0.865) and the mixed subscale correlated with the YMRS (r = 0.750). Conclusion: The BDRS has good internal validity and inter-rater reliability and is sensitive to change in the context of a clinical trial. [source]


The impact of age at onset of bipolar I disorder on functioning and clinical presentation

ACTA NEUROPSYCHIATRICA, Issue 4 2009

Objectives: Recent studies have proposed the existence of three distinct subgroups of bipolar 1 disorder based on age at onset (AAO). The present study aims to investigate potential clinical and functional differences between these subgroups in an Australian sample. Methods: Participants (n = 239) were enrolled in the Bipolar Comprehensive Outcomes Study (BCOS), a 2-year longitudinal, observational, cross-sectional study. Assessment measures included the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAMD21), Clinical Global Impressions Scale (CGI-BP), SF-36, SLICE/Life Scale, and the EuroQol (EQ-5D). Participants were also asked about their age at the first major affective episode. Results: Three AAO groups were compared: early (AAO < 20, mean = 15.5 ± 2.72; 44.4% of the participants); intermediate (AAO 20,39, mean = 26.1 ± 4.8; 48.14% of the participants) and late (AAO > 40, mean = 50.6 ± 9.04; 7.4% of the participants). Higher rates of depression, suicidal ideation and binge drinking were reported by the early AAO group. This group also reported poorer quality of life in a number of areas. The early AAO group had a predominant depressive initial polarity and the intermediate group had a manic predominance. Conclusion: Early AAO is associated with an adverse outcome. [source]


Safety, tolerability and efficacy of a rapid dose escalation of quetiapine in bipolar I mania: the FATIMA study

ACTA NEUROPSYCHIATRICA, Issue 3 2009
Eric Constant
Objective: The FATIMA study (FAst TItration of quetiapine fumarate in bipolar I MAnia) evaluated the safety, tolerability and efficacy of a rapid dose escalation of quetiapine in acutely ill bipolar I patients experiencing a manic episode. Methods: In an open-label, phase II pilot study, 29 patients aged 18 years or older, hospitalised with a bipolar I manic episode, received quetiapine twice daily for 21 days. Quetiapine was administered at 200, 400, 600, then 800 mg/day on the first 4 days, with flexible dosing (400,800 mg/day) subsequently. The primary endpoint was the proportion of patient dropouts because of adverse drug reactions during the first 7 days. Secondary safety assessments included incidences of adverse drug reactions and significant changes in vital signs. Efficacy assessments included Young Mania Rating Scale (YMRS) and Clinical Global Impressions Severity of Illness (CGI-S) score changes from day 1 to day 21. Results: Twenty patients (69%) completed the study. No patients withdrew as a result of drug-related adverse events (AEs) during the first 7 days. Twenty-three patients reported 58 adverse events, and most of the adverse events were mild or moderate. No clinically relevant abnormalities in vital signs were reported. Mean YMRS and CGI-S scores decreased significantly from baseline to day 21 (p < 0.001). Response and remission rates were 78 and 70%, respectively, at the end of the study. Conclusion: Rapid dose escalation of quetiapine to 800 mg/day over 4 days was well tolerated and effective in reducing symptoms within 5 days in acutely ill bipolar I patients with a manic episode.

Effect of risperidone on plasma catecholamine metabolites and brain-derived neurotrophic factor in patients with bipolar disorders

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2006
Reiji Yoshimura
Abstract A combination treatment with a mood stabilizer and an antipsychotic drug is often used in as many as 90% of subjects with acute mania. Recently, augmentation therapy with atypical antipsychotics has been investigated in both the acute and long-term treatment of bipolar disorder with or without psychosis. In the present study, the authors investigated the efficacy of risperidone treatment for both acute manic and depressive episodes in bipolar disorder. Eighteen patients (M/F: 8/10, age: 34,±,15,yr) who met the DSM-IV criteria for bipolar I disorder (12 cases of manic episodes, 6 cases of depressive episodes) with risperidone treatment were evaluated regarding their clinical improvement using the Young Mania rating Scale (YMRS) and the Hamilton rating Scale for Depression (Ham-D). Plasma concentrations of HVA and MHPG were analyzed by HPLC-ECD and plasma brain-derived neurotrophic factor (BDNF) levels were detected by sandwich ELISA. The mean scores of the YMRS were 22, 18, 12, 8, and 5 at time points before and 1, 2, 3, and 4 weeks after the risperidone administration, respectively. The mean scores of the Ham-D were 24, 25, 21, 21, and 19 at time points before and 1, 2, 3, and 4 weeks after the risperidone administration, respectively. The plasma levels of HVA and 3-methoxy-4-hydroxyphenylglycol (MHPG) were observed to have decreased 4 weeks after risperidone administration in manic patients. The levels did not change in depressive patients. The plasma levels of BDNF were decreased in depressive patients compared with manic patients or healthy controls. However, the administration of risperidone did not alter plasma BDNF levels. Copyright © 2006 John Wiley & Sons, Ltd. [source]
