RESUMO

OBJECTIVE: To determine if acute treatment with aripiprazole (APZ) would be superior to treatment with placebo in reducing dysfunctional symptoms of elevated mood and/or irritability in symptomatic children and adolescents at familial high risk for bipolar disorder (BPD) whose mood episodes occur spontaneously. These are patients we have previously referred to as suffering from "cyclotaxia." METHODS: This was single-site, randomized, double-blind, placebo-controlled outpatient clinical trial in which youths aged 5-17 years who met diagnostic criteria for either cyclothymic disorder (CYC) or BPD not otherwise specified (BP-NOS) were randomly assigned to receive either APZ or placebo. Eligible participants had at least one parent with BPD, another first- or second-degree relative afflicted with a mood disorder, and also had not responded to psychotherapy. Treatment with APZ was initiated at a dose of approximately 0.1 mg/kg/day and could be increased by approximately 0.05 mg/kg/day at each study visit. Patients were seen weekly for 4 weeks and then every other week thereafter for 12 weeks. The primary outcome measure was mean change from baseline on Young Mania Rating Scale (YMRS) total score. RESULTS: A total of 59 patients (30 APZ, 29 placebo) aged 11.8 (SD = 2.7) years were randomized and returned for at least one postbaseline assessment. The mean total daily doses of active APZ and placebo were 7.1 mg (SD = 3.7) and 7.4 mg (SD = 4.2), respectively. At the 12-week time point, APZ was superior to placebo on the primary outcome measure (p < 0.005). Most adverse events were mild and transient in nature. There was a significant difference in weight gain from baseline between patients who received APZ (2.3 kg [SD = 3.3]) and those who received placebo (0.7 kg [SD = 1.8]). CONCLUSION: This double-blind trial found that APZ was significantly more efficacious than placebo in reducing symptoms of mania in children and adolescents with cyclotaxia.

RESUMO

Our recent 8-week, randomized, placebo-controlled trial of fluoxetine in adolescents (ages 12-17 years) with comorbid depression and substance use disorder (SUD) did not detect a significant antidepressant treatment effect. The purpose of this secondary analysis was to explore moderators of the effect of fluoxetine in this sample. Static moderators measured at baseline were depression chronicity and hopelessness severity; time-varying moderators measured at baseline and weekly during the 8-week trial period were alcohol and marijuana use severity. Treatment effects on depression outcomes were examined among moderating subgroups in random effects regression models. Subjects assigned to fluoxetine treatment with chronic depression at baseline (p = .04) or no more than moderate alcohol use during the trial (p = .04) showed significantly greater decline in depression symptoms in comparison to placebo-assigned subgroups. The current analysis suggests that youth with chronic depression and no more than moderate alcohol consumption are likely to respond better to treatment with fluoxetine compared with placebo than youth with transient depression and heavy alcohol use.

RESUMO

BACKGROUND: This study evaluates the long-term efficacy of aripiprazole compared to placebo in children with bipolar disorders. METHOD: Outpatients aged 4 to 9 years meeting DSM-IV criteria for a bipolar disorder (I, II, not otherwise specified, cyclothymia) were eligible to receive up to 16 weeks of open-label treatment with aripiprazole (phase 1). Patients were randomized into the 72-week double-blind phase of the study once they met a priori response criteria for stabilization (phase 2). During phase 2, patients either remained on their current aripiprazole regimen or began a double-blind taper with aripiprazole discontinued and switched to placebo. The primary outcome measure for phase 2 was time to discontinuation due to a mood event. RESULTS: Patients were recruited between May 2004 and November 2008. Following phase 1, in which 96 patients received aripiprazole, 30 patients (mean age = 7.1 years) were randomly assigned to continue aripiprazole and 30 patients (mean age = 6.7 years) were randomly assigned to placebo. The mean (SD) dose of aripiprazole prior to randomization for these patients was 6.4 (2.1) mg/d. Patients randomly assigned to aripiprazole were enrolled significantly longer until time to study discontinuation due to a mood event (6.14 median weeks, SE ± 11.88 weeks; P = .005) and discontinuation for any reason (including mood events) (4.00 median weeks, SE ± 3.91 weeks; P = .003) than those randomly assigned to placebo (mood event, 2.29 median weeks, SE ± 0.38 weeks; any reason, 2.00 median weeks, SE ± 0.31 weeks). Regardless of random assignment, both the aripiprazole and placebo groups showed substantial rates of withdrawal from maintenance treatment over the initial 4 weeks (15/30 [50%] for aripiprazole; 27/30 [90%] for placebo), suggesting a possible nocebo effect (ie, knowledge of possibly switching from active medication to placebo increasing concern about relapse). The most frequently reported adverse events during double-blind aripiprazole therapy included stomach pain (n = 10, 33%), increased appetite (n = 9, 30%), and headaches (n = 9, 30%). CONCLUSIONS: Despite the possibility of a nocebo effect, these results suggest that aripiprazole may be superior to placebo in the long-term treatment of pediatric patients following stabilization with open-label aripiprazole.

RESUMO

OBJECTIVE: The purpose of this open-label study was to describe the effectiveness of aripiprazole (APZ) in the treatment of children with bipolar disorders suffering from manic symptomatology. METHOD: Symptomatic outpatients (Young Mania Rating Scale [YMRS] score ≥15) meeting strict, unmodified, Diagnostic and Statistical Manual of Mental Disorders, 4th edition, diagnostic symptom criteria for a bipolar disorder, ages 4-9 years, were eligible. Subjects were treated prospectively with flexible doses of APZ (maximum daily dose of 15 mg/day), for up to 16 weeks or until a priori response criteria were met. Outcome measures included the YMRS, Clinical Global Impressions Scale-Severity, Children's Global Assessment Scale (CGAS), and the Children's Depression Rating Scale-Revised (CDRS-R). A priori response criteria consisted of 3 of 4 consecutive weeks with (1) CDRS-R <29; (2) YMRS <10; and (3) CGAS >50. RESULTS: Ninety-six children (62 males; mean age of 6.9 (SD = 1.7), received APZ for an average length of treatment of 12.5 (SD = 3.9) weeks. Significant improvements in YMRS, CDRS-R, CGAS, and Clinical Global Impressions Scale-Severity scores (p < 0.001) were noted at the end of study participation. Sixty of the subjects (62.5%) met a priori response criteria at study's end. The most common side effects noted were stomachache, increased appetite, and headache. Two subjects were removed from the study due to side effects [epistaxis (n = 1); akathisia (n = 1)]. Subjects experienced an average weight gain of 2.4 (SD = 1.9) kg. CONCLUSION: APZ may be effective in the acute treatment of symptoms of children with bipolar illnesses.

RESUMO

BACKGROUND: The objective of this study was to examine whether fluoxetine was superior to placebo in the acute amelioration of depressive symptomatology in adolescents with depressive illness and a comorbid substance use disorder. METHODS: Eligible subjects ages 12-17 years with either a current major depressive disorder (MDD) or a depressive disorder that were also suffering from a comorbid substance-related disorder were randomized to receive either fluoxetine or placebo in this single site, 8-week double-blind, placebo-controlled study. The primary outcome analysis was a random effects mixed model for repeated measurements of Children's Depression Rating Scale-Revised (CDRS-R) scores compared between treatment groups across time. RESULTS: An interim analysis was performed after 34 patients were randomized. Based on the results of a futility analysis, study enrollment was halted. Twenty-nine males and 5 females were randomized to receive fluoxetine (n = 18) or placebo (n = 16). Their mean age was 16.5 (1.1) years. Overall, patients who received fluoxetine and placebo had a reduction in CDRS-R scores. However, there was no significant difference in mean change in CDRS-R total score in those subjects treated with fluoxetine and those who received placebo (treatment difference = 0.19, S.E. = 0.58, F = 0.14, p = .74). Furthermore, there was not a significant difference in rates of positive urine drug toxicology results between treatment groups at any post-randomization visit (F = 0.22, df = 1, p = 0.65). The main limitation of this study is its modest sample size and resulting low statistical power. Other significant limitations to this study include, but are not limited to, the brevity of the trial, high placebo response rate, limited dose range of fluoxetine, and the inclusion of youth who met criteria for depressive disorders other than MDD. CONCLUSION: Fluoxetine was not superior to placebo in alleviating depressive symptoms or in decreasing rates of positive drug screens in the acute treatment of adolescents with depression and a concomitant substance use disorder.

RESUMO

OBJECTIVE: To examine the effectiveness and cognitive effects of aripiprazole (APZ) in children with a primary diagnosis of attention-deficit/hyperactivity disorder (ADHD). METHODS: Youths, ages 8-12 years, with a diagnosis of ADHD combined-type or ADHD predominately inattentive-type were enrolled into a 6-week, open-label pilot trial. Outcome measures included the ADHD Rating Scale-IV (ARS-IV), Clinical Global Impressions Scale (CGI), and Children's Global Assessment Scale (CGAS). The Conners' Continuous Performance Test II, Reading and Math Fluency subscales of the Woodcock-Johnson III Tests of Achievement, and the Stroop Color and Word Test were administered at baseline and end of study. RESULTS: Fourteen (9 males and 5 females) youths were diagnosed with ADHD-combined type, while 9 (5 males and 4 females) were diagnosed with ADHD-inattentive type. At a mean dose of 6.7 mg/day, end of study results showed overall significant improvement from baseline on ADHD and functional outcome measures. No significant differences in baseline performance at end of study were found on the cognitive measures. The most frequently reported adverse events were sedation (n = 18; 78.3%) and headache (n = 11; 47.8%). CONCLUSIONS: Although this was a brief pilot study with a small sample size, in this cohort, APZ led to clinical benefit in reducing ADHD symptoms and improving overall functioning. Of note, cognitive functioning did not appear to be negatively impacted by APZ treatment.

RESUMO

OBJECTIVE: To examine the short-term efficacy of methylphenidate in the treatment of youths with bipolar disorder (BD) and comorbid attention deficit/hyperactivity disorder (ADHD). METHOD: A 4-week double-blind, placebo-controlled trial in youths ages 5 to 17 years was conducted. Subjects met DSM-IV criteria for bipolar disorder and ADHD, were currently receiving a stable dose of at least one thymoleptic, and while euthymic continued to have clinically significant symptoms of ADHD. Patients received 1 week each of placebo, methylphenidate 5 mg twice daily, methylphenidate 10 mg twice daily, and methylphenidate 15 mg twice daily using a crossover design. Subjects were randomly assigned to receive one of six possible dosing orders. At study's end, and before the blind being broken, a "best dose week" for each subject was determined. The primary outcome measure was the total score on the parent-completed ADHD Rating Scale-IV. RESULTS: Sixteen patients, with a mean age of 10.43 (SD 3.14) years completed the trial. Lower scores during best dose treatment compared to the week of placebo treatment were found on the ADHD Rating Scale-IV (p < .05), suggesting a therapeutic benefit. A large effect size (Cohen's d = 0.90) was found for methylphenidate. Treatment was generally well tolerated. CONCLUSIONS: Euthymic youths with bipolar disorder and ADHD may benefit from short-term concomitant treatment with methylphenidate.

RESUMO

OBJECTIVE: The objective of this study was to describe the prevalence and correlates of adherence to divalproex sodium (DVPX) and lithium carbonate (Li) combination treatment during the initial stabilization treatment phase. METHOD: Adherence to Li/DVPX combination therapy was measured by the presence or absence of minimum serum concentrations of DVPX (50 microg/mL) or Li (0.6 mmol/L). Secondary measures included pill count, patient/parent report, and clinical judgment. Correlates of adherence, including patient characteristics, medication side effects, and family variables, were evaluated. RESULTS: One hundred seven patients (70 males and 37 females) were studied. The proportion of serum concentrations in the therapeutic range across the study period was 0.84 for DVPX and 0.66 for Li. Maternal (r = -0.31; p<.01) and paternal (r = -0.44; p < .01) hospitalization for a psychiatric disorder and less adaptive family functioning (r=-0.26; p < .05) related to treatment nonadherence for DVPX. Better treatment adherence to DVPX (r = 0.21; p < .05) and Li (r = 0.23; p < .05) was associated with a greater number of side effects, whereas male sex was associated with worse adherence to both DVPX (r= -0.24; p < .05) and Li (r = -0.22; p < .05) pharmacotherapy. Clinical response to treatment correlated with adherence to DVPX treatment (r = 0.33; p < .01). CONCLUSIONS: Nonadherence may limit the statistical power of treatment efficacy studies and the effectiveness of pharmacotherapy treatment for juvenile BPD and necessitate strategies to evaluate and enhance levels of treatment adherence.

RESUMO

OBJECTIVE: To determine if divalproex sodium was superior to placebo in the treatment of symptomatic youths who suffer from a bipolar spectrum disorder and who also have a parent with a diagnosis of a bipolar illness. METHOD: Youths, ages 5 to 17 years, meeting DSM-IV criteria for bipolar disorder not otherwise specified (NOS) or cyclothymia who also had at least 1 biological parent with bipolar illness were randomly assigned in a double-blind fashion to receive treatment with either dival-proex sodium or placebo for up to 5 years. Study participation ended if the subject required additional clinical intervention, if the patient developed treatment-related adverse events, or if the participant was not adherent with study procedures. The primary outcome measure was time to study discontinuation for any reason. The study was conducted from August 1997 to April 2003. RESULTS: Fifty-six youths with a mean (SD) age of 10.7 (3.1) years were randomly assigned and received either divalproex sodium (N = 29) or placebo (N = 27). In spite of statistical power of 80% to detect hazard ratios of 2.2 or larger, the treatment groups did not significantly differ in survival time for discontinuation for any reason (p = .93) or discontinuation due to a mood event (p = .55). Changes in mood symptom ratings and psychosocial functioning from baseline to study discontinuation did not differ between groups (most significant p > .14). However, both groups did show improvements in mood symptoms and psychosocial functioning over time (all p values < .002). One patient, from the placebo group, ended study participation due to an adverse event. CONCLUSION: These results suggest that, although well tolerated, divalproex sodium does not produce clinically meaningful improvements in the treatment of symptomatic youths suffering from either bipolar NOS or cyclothymia who are at genetic risk for developing bipolar disorder.

RESUMO

OBJECTIVE: The aim of this study was to describe the long-term safety and effectiveness of quetiapine in conduct disorder (CD). METHODS: This was an 18-week outpatient follow-up study of an acute trial that enrolled aggressive children ages 6-12 years with a primary diagnosis of CD. To be enrolled into this study, subjects had to have successfully completed participation in the initial 8-week, open-label, outpatient quetiapine trial. Psychometric measures included the Rating of Aggression Against People and/or Property Scale (RAAPP), the Nisonger Child Behavior Rating Form (NCBRF), the Conners' Parent Rating Scale (CPRS-48), the Clinical Global Impressions Scale of Severity (CGI-S), and the Children's Global Assessment Scale. RESULTS: Nine males with a mean age of 8.9 (SD = 1.2) years were treated. The median quetiapine dose at end of study was 150 mg/day (range 75-350). Mean psychometric scores did not change substantively from baseline. No patients experienced extrapyramidal side effects. Three subjects discontinued due to study nonadherence. No patients discontinued treatment due to an adverse event. CONCLUSIONS: These preliminary data suggest that quetiapine might be a generally safe and effective maintenance treatment for aggressive children with CD who initially respond to an acute therapeutic trial of quetiapine. More research is needed to confirm or refute these initial findings.

RESUMO

BACKGROUND: Disturbances in N-methyl-D-aspartate (NMDA) receptor activity may play a role in attention-deficit/hyperactivity disorder (ADHD). OBJECTIVE: This study is a preliminary evaluation of the safety, pharmacokinetics, and effectiveness of the NMDA receptor antagonist memantine in pediatric ADHD. METHODS: An open-label, dose-finding, 8-week, trial in outpatients 6-12 years old with ADHD combined type. Memantine oral solution (2 mg/mL) was titrated to 10 mg/day (n = 8) or 20 mg/day (n = 8). Safety data and blood samples for pharmacokinetic analyses were collected. The ADHD Rating Scale-IV (ADHD-IV) and Clinical Global Impression of Severity (CGI-S) scale measured the effectiveness of memantine. RESULTS: There were no discontinuations due to adverse events (AEs), serious AEs, deaths, or suicides. Most AEs were mild and occurred during the first week of treatment. The 20 mg/day memantine dose was associated with a higher rate of completion and larger mean improvement on the ADHD-IV and CGI-S than 10 mg/day memantine. Pharmacokinetic analyses suggest response to memantine may be dose-dependent beyond an initial threshold concentration. CONCLUSIONS: This pilot study suggests that a memantine dose of 20 mg/day may be a safe and possibly effective treatment for pediatric ADHD. Further investigations of memantine in ADHD appear to be warranted.

RESUMO

The primary objective of this study was to evaluate the psychometric characteristics of the Young Mania Rating Scale (YMRS), the K-SADS Mania Rating Scale (KMRS), and the Children's Depression Rating Scale-Revised (CDRS-R) across four age groups (4-7, 8-10, 11-13, and 14-17 years). The interrater reliability of K-SADS diagnoses was also examined. Participants included 1,014 youths (62.1% male) presenting to an outpatient clinical research center. Diagnoses were based upon semistructured K-SADS interviews. Symptomatic assessments and ratings of psychosocial functioning were completed following the diagnostic interview. Mania measures showed unifactorial structure and good internal consistency reliability (alpha = 0.79-0.95) across all ages groups. The CDRS-R factor structure shifted from one to two factors in adolescents. For all ages and symptom measures, reliability was excellent in the range where differential diagnosis is most difficult. Efficiencies in discriminating bipolar spectrum disorders from other disorders were excellent (areas under the curve, AUCs = 0.92-0.99) for mania measures, with comparable discrimination across age groups. Interrater reliability of K-SADS diagnoses was excellent across age groups (smallest kappa = 0.95). Results indicate that mania measures are useful for assessing symptoms across a wide range of ages. The CDRS-R may be better conceptualized as a two-factor measure in older adolescents. The semistructured K-SADS interview can be used to generate reliable diagnoses across a broad age range.

RESUMO

OBJECTIVE: To provide an initial description of the effectiveness and pharmacokinetics (PK) of quetiapine in aggressive children with conduct disorder (CD). METHOD: This 8-week, open-label outpatient trial, enrolled patients ages 6 to 12 years with CD. Outcome measures included the Rating of Aggression Against People and/or Property Scale (RAAPPS), Nisonger Child Behavior Rating Form (NCBRF), and the Conners Parent Rating Scale (CPRS-48). Blood sampling for PK analyses occurred at the end of weeks 2 and 8. RESULTS: Seventeen children (16 boys, mean age 8.9 years) were treated. The mean dose at week 8 was 4.4 mg/kg (SD = 1.1 mg/kg). Significant decreases in the baseline scores of the RAAPPS, and several subscales of the NCBRF and the CPRS were found by the end of the study (p <.05). No patients discontinued because of an adverse event. No patients experienced extrapyramidal side effects. Quetiapine disposition was linear over the dose range studied. The elimination half-life of the drug averaged 3.9 and 2.9 hours and total body clearance averaged 3.5 and 3.0 L/hr/kg after study weeks 2 and 8, respectively. CONCLUSIONS: These preliminary data suggest that aggressive children with CD may benefit from quetiapine. The PK of quetiapine supports twice-daily dosing in children with CD.

RESUMO

INTRODUCTION: Identifying evidence-based dosing strategies is a key part of new drug development in pediatric populations. Pharmacokinetic (PK) studies can provide important information regarding how best to dose medications in children and adolescents. Utilizing scientifically supported dosing strategies provides the best chance for any given drug to demonstrate both efficacy and acceptable tolerability in definitive, placebo-controlled studies. METHODS: Results of both PK studies and randomized, placebo-controlled efficacy trials (RPCTs) in juvenile major depressive disorder (MDD) are reviewed. The degree to which the medication dosing strategies that were employed in the efficacy studies were supported by the extant PK data is considered. Medications that are reviewed include fluoxetine, sertraline, paroxetine, citalopram, escitalopram, venlafaxine, nefazodone, and mirtazapine. RESULTS: In many instances, the dosing paradigms that were used in the RPCTs differed, sometimes substantially, from the dosing strategies that would have been supported based on the results of PK studies. CONCLUSIONS: Medication dosing regimens may have contributed to the failure of several RPCTs to show drug efficacy in the treatment of pediatric MDD. In addition, the doses of medication used in these RPCTs may also have contributed to the safety and tolerability concerns that have been raised with these drugs. PK and dose-ranging studies should be performed prior to the initiation of definitive efficacy trials so that empirically supported dosing strategies can be incorporated into the design of RPCTs of antidepressants in children and adolescents suffering from MDD.

OBJECTIVES: The objectives of this study were to: (i) describe the phenomenology of youths diagnosed with subsyndromal bipolar disorders; (ii) describe the phenomenology of youngsters who are the children of bipolar parents, who are also experiencing subsyndromal symptoms of bipolar disorder (patients with 'cyclotaxia'); and (iii) explore which symptoms may be most useful in identifying youths with cyclotaxia. METHODS: Four hundred outpatients between the ages of 5 and 17 years received a diagnostic assessment and psychometric questionnaires pertaining to mood symptomatology and psychosocial functioning. Parental diagnostic information was also obtained. Children and adolescents were assigned to one of three diagnostic groups: a 'syndromal bipolar disorder (BP)' group (n = 118), a 'sub-syndromal bipolar (SUB-BP)' group (n = 75), or a 'non-bipolar (NON-BP)' group (n = 207). In addition, based on parental diagnoses, youths were assigned to either a high genetic risk group (n = 167) or a low genetic risk group (n = 233). RESULTS: Youths with subsyndromal bipolar disorders were found to have intermediate degrees of manic symptoms than youths with bipolar disorder and youths without a bipolar diagnosis. Offspring of parents having a bipolar disorder were more likely to show symptoms of hypomania and mania than youths without a bipolar parent. Youths at genetic risk for developing a bipolar disorder were not found to be at higher risk for having a diagnosis of attention-deficit hyperactivity disorder or a disruptive behavior disorder. Finally, results suggest that elevated mood with irritability and rapid mood fluctuations are the key distinguishing characteristics of 'cyclotaxia'. CONCLUSIONS: There exists a group of youngsters who are the offspring of a parent/parents with a bipolar disorder who do not suffer from BP 1 or BP 2, yet have elevated mood symptoms and psychosocial dysfunction. As a result of these observations, treatment studies are needed for youths with 'cyclotaxia'.

RESUMO

Numerous somatic interventions have been studied as potential treatments of depressive disorders in children and adolescents. These include antidepressant medications, light therapy, electro-convulsive therapy, and alternative therapies. The available evidence suggests that several somatic interventions hold promise as potentially safe and effective treatments for depressed youths; however, there is still much to be learned about these interventions. This article reviews what is known and what needs to be learned about the somatic treatment of pediatric depression.

RESUMO

OBJECTIVE: Lithium carbonate (Li) or divalproex sodium (DVPX) may be effective for some juveniles with bipolar disorder. Many youths with bipolar disorder do not respond to DVPX or Li monotherapy. An open-label study was conducted to examine the effectiveness of combination DVPX and Li therapy with youths diagnosed with bipolar disorder. METHOD: Patients meeting DSM-IV criteria for bipolar I or bipolar II disorder, ages 5 to 17 years, were treated prospectively for up to 20 weeks with DVPX + Li. Assessments included the Young Mania Rating Scale (YMRS), Children's Depression Rating Scale-Revised (CDRS-R), and the Children's Global Assessment Scale (CGAS). The a priori definition of clinical remission utilized included four contiguous weekly ratings of YMRS /=51, clinical stability, and no evidence of mood cycling. RESULTS: Ninety patients (66 males, 24 females) were treated. Significant improvement (p <.0001) in all outcome measures was observed by week 8 as well as at the end of study. The mean time in study was 11.3 weeks. Forty-seven percent (n = 42) met a priori criteria for remission. CONCLUSIONS: Symptoms of mania and depression in juvenile bipolar disorder may be safely and effectively treated acutely with DVPX + Li.
