quetiapine-fumarate and Attention-Deficit-Disorder-with-Hyperactivity

This is an update of the original Cochrane Review, last published in 2012 (Loy 2012). Children and youths with disruptive behaviour disorders may present to health services, where they may be treated with atypical antipsychotics. There is increasing usage of atypical antipsychotics in the treatment of disruptive behaviour disorders.. To evaluate the effect and safety of atypical antipsychotics, compared to placebo, for treating disruptive behaviour disorders in children and youths. The aim was to evaluate each drug separately rather than the class effect, on the grounds that each atypical antipsychotic has different pharmacologic binding profile (Stahl 2013) and that this is clinically more useful.. In January 2017, we searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers.. Randomised controlled trials of atypical antipsychotics versus placebo in children and youths aged up to and including 18 years, with a diagnosis of disruptive behaviour disorders, including comorbid ADHD. The primary outcomes were aggression, conduct problems and adverse events (i.e. weight gain/changes and metabolic parameters). The secondary outcomes were general functioning, noncompliance, other adverse events, social functioning, family functioning, parent satisfaction and school functioning.. We used standard methodological procedures expected by Cochrane. Two review authors (JL and KS) independently collected, evaluated and extracted data. We used the GRADE approach to assess the quality of the evidence. We performed meta-analyses for each of our primary outcomes, except for metabolic parameters, due to inadequate outcome data.. We included 10 trials (spanning 2000 to 2014), involving a total of 896 children and youths aged five to 18 years. Bar two trials, all came from an outpatient setting. Eight trials assessed risperidone, one assessed quetiapine and one assessed ziprasidone. Nine trials assessed acute efficacy (over four to 10 weeks); one of which combined treatment with stimulant medication and parent training. One trial was a six-month maintenance trial assessing symptom recurrence.The quality of the evidence ranged from low to moderate. Nine studies had some degree of pharmaceutical support/funding. Primary outcomesUsing the mean difference (MD), we combined data from three studies (238 participants) in a meta-analysis of aggression, as assessed using the Aberrant Behaviour Checklist (ABC) ‒ Irritability subscale. We found that youths treated with risperidone show reduced aggression compared to youths treated with placebo (MD -6.49, 95% confidence interval (CI) -8.79 to -4.19; low-quality evidence). Using the standardised mean difference (SMD), we pooled data from two risperidone trials (190 participants), which used different scales: the Overt Aggression Scale ‒ Modified (OAS-M) Scale and the Antisocial Behaviour Scale (ABS); as the ABS had two subscales that could not be combined (reactive and proactive aggression), we performed two separate analyses. When we combined the ABS Reactive subscale and the OAS-M, the SMD was -1.30 in favour of risperidone (95% CI -2.21 to -0.40, moderate-quality evidence). When we combined the ABS Proactive subscale and OAS-M, the SMD was -1.12 (95% CI -2.30 to 0.06, moderate-quality evidence), suggesting uncertainty about the estimate of effect, as the confidence intervals overlapped the null value. In summary, there was some evidence that aggression could be reduced by risperidone. Data were lacking on other atypical antipsychotics, like quetiapine and ziprasidone, with regard to their effects on aggression.We pooled data from two risperidone trials (225 participants) in a meta-analysis of conduct problems, as assessed using the Nisonger Child Behaviour Rating Form ‒ Conduct Problem subscale (NCBRF-CP). This yielded a final mean score that was 8.61 points lower in the risperidone group compared to the placebo group (95% CI -11.49 to -5.74; moderate-quality evidence).We investigated the effect on weight by performing two meta-analyses. We wanted to distinguish between the effects of antipsychotic medication only and the combined effect wit. There is some evidence that in the short term risperidone may reduce aggression and conduct problems in children and youths with disruptive behaviour disorders There is also evidence that this intervention is associated with significant weight gain.For aggression, the difference in scores of 6.49 points on the ABC ‒ Irritability subscale (range 0 to 45) may be clinically significant. It is challenging to interpret the clinical significance of the differential findings on two different ABS subscales as it may be difficult to distinguish between reactive and proactive aggression in clinical practice. For conduct problems, the difference in scores of 8.61 points on the NCBRF-CP (range 0 to 48) is likely to be clinically significant. Weight gain remains a concern.Caution is required in interpreting the results due to the limitations of current evidence and the small number of high-quality trials. There is a lack of evidence to support the use of quetiapine, ziprasidone or any other atypical antipsychotic for disruptive behaviour disorders in children and youths and no evidence for children under five years of age. It is uncertain to what degree the efficacy found in clinical trials will translate into real-life clinical practice. Given the effectiveness of parent-training interventions in the management of these disorders, and the somewhat equivocal evidence on the efficacy of medication, it is important not to use medication alone. This is consistent with current clinical guidelines.

Disruptive behaviour disorders include conduct disorder, oppositional defiant disorder and disruptive behaviour not otherwise specified. Attention deficit hyperactivity disorder (ADHD) is frequently associated with disruptive behaviour disorders. The difficulties associated with disruptive behaviour disorders are demonstrated through aggression and severe behavioural problems. These often result in presentation to psychiatric services and may be treated with medications such as atypical antipsychotics. There is increasing evidence of a significant rise in the use of atypical antipsychotics for treating disruptive behaviour disorders in child and adolescent populations.. To evaluate the effect and safety of atypical antipsychotics, compared to placebo, for treating disruptive behaviour disorders in children and youths. . We searched the following databases in August 2011: CENTRAL (2011, Issue 3), MEDLINE (1948 to August Week 1), EMBASE (1980 to 2011 Week 32), PsycINFO (1806 to August Week 2 2011), CINAHL (1937 to current), ClinicalTrials.gov (searched 15 August 2011), Australian New Zealand Clinical Trials Registry (ANZCTR) (searched 15 August 2011), CenterWatch (searched 15 August 2011) and ICTRP (searched 15 August 2011).. We included randomised controlled trials with children and youths up to and including the age of 18, in any setting, with a diagnosis of a disruptive behaviour disorder. We included trials where participants had a comorbid diagnosis of attention deficit hyperactivity disorder, major depression or an anxiety disorder.. Two review authors independently selected the studies and disagreements were resolved by discussion. Two review authors extracted data independently. One review author entered data into Review Manager software and another checked it. We contacted trial authors for information about adverse effects and to provide missing data.. We included eight randomised controlled trials, spanning 2000 to 2008. Seven assessed risperidone and one assessed quetiapine. Three of the studies were multicentre. Seven trials assessed acute efficacy and one assessed time to symptom recurrence over a six-month maintenance period.We performed meta-analyses for the primary outcomes of aggression, conduct problems and weight changes but these were limited by the available data as different trials reported either mean change scores (average difference) or final/post-intervention raw scores and used different outcome measures. We also evaluated each individual trial's treatment effect size where possible, using Hedges' g.For aggression, we conducted two meta-analyses. The first included three trials (combined n = 238) using mean difference (MD) on the Aberrant Behaviour Checklist (ABC) Irritability subscale. Results yielded a final mean score with treatment that was 6.49 points lower than the post-intervention mean score with placebo (95% confidence interval (CI) -8.79 to -4.19). The second meta-analysis on aggression included two trials (combined n = 57) that employed two different outcome measures (Overt Aggression Scale (modified) (OAS-M) and OAS, respectively) and thus we used a standardised mean difference. Results yielded an effect estimate of -0.18 (95% CI -0.70 to 0.34), which was statistically non-significant.We also performed two meta-analyses for conduct problems. The first included two trials (combined n = 225), both of which employed the Nisonger Child Behaviour Rating Form - Conduct Problem subscale (NCBRF-CP). The results yielded a final mean score with treatment that was 8.61 points lower than that with placebo (95% CI -11.49 to -5.74). The second meta-analysis on conduct problems included two trials (combined n = 36), which used the Conners' Parent Rating Scale - Conduct Problem subscale (CPRS-CP). Results yielded a mean score with treatment of 12.67 lower than with placebo (95% CI -37.45 to 12.11), which was a statistically non-significant result.With respect to the side effect of weight gain, a meta-analysis of two studies (combined n = 138) showed that participants on risperidone gained on average 2.37 kilograms more than those in the placebo group over the treatment period (MD 2.37; 95% CI 0.26 to 4.49).For individual trials, there was a range of effect sizes (ranging from small to large) for risperidone reducing aggression and conduct problems. The precision of the estimate of the effe. There is some limited evidence of efficacy of risperidone reducing aggression and conduct problems in children aged 5 to 18 with disruptive behaviour disorders in the short term.For aggression, the difference in scores of 6.49 points on the ABC Irritability subscale (range 0 to 45) may be clinically significant. For conduct problems, the difference in scores of 8.61 points on the NCBRF-CP (range 0 to 48) is likely to be clinically significant.Caution is required due to the limitations of the evidence and the small number of relevant high-quality studies. The findings from the one study assessing impact in the longer term suggest that the effects are maintained to some extent (small effect size) for up to six months. Inadequately powered studies produced non-significant results. The evidence is restricted by heterogeneity of the population (including below average and borderline IQ), and methodological issues in some studies, such as use of enriched designs and risk of selection bias. No study addressed the issue of pre-existing/concurrent psychosocial interventions, and comorbid stimulant medication and its dosage was only partially addressed. There is currently no evidence to support the use of quetiapine for disruptive behaviour disorders in children and adolescents.It is uncertain to what degree the efficacy found in clinical trials will translate into real life clinical practice. Participants in the studies were recruited from clinical services but those who agree to take part in the clinical trials are a subset of the overall population presenting for care. There are no research data for children under five years of age. Further high-quality research is required with large samples of clinically representative youths and long-term follow-up to replicate current findings.

Disruptive behavior disorders, including conduct disorder, oppositional defiant disorder, and disruptive behavior disorder not otherwise specified, are serious conditions in children and adolescents that include a behavior pattern of violating the basic rights of others and age-appropriate rules or standards and may include aggressive behavior. Although no pharmacotherapy is currently approved for use in this population, evidence suggests that atypical antipsychotic treatment may be useful in patients with these conditions who present with problematic aggression. Currently, research on risperidone shows it to be effective in treating aggressive behavior in this patient population. Limited research is also available on olanzapine, quetiapine, and aripiprazole, but more research is needed on these and other agents. As with any pharmacotherapy, adverse events (including weight gain, headache, and somnolence) should be carefully considered with these medications, especially in children and adolescents, and it is important to properly dose and monitor patients during medication therapy.

The aim of this study was to describe the long-term safety and effectiveness of quetiapine in conduct disorder (CD).. 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.. 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.. 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.

This study investigated the safety and efficacy of adding the atypical antipsychotic quetiapine to ongoing OROS methylphenidate treatment for adolescents with comorbid ADHD and severe aggression that were incompletely responsive to methylphenidate monotherapy.. Participants aged 12-16 years were enrolled in a prospective, open-label trial consisting of 3 weeks of OROS methylphenidate monotherapy titrated to 54 mg/day, followed by 9 weeks of combination treatment with quetiapine and methylphenidate. Twenty-four out of thirty participants failed to meet criteria for significant improvement (Clinical Global Improvement-Severity [CGI-S] and Rating of Aggression Against People and Property [RAAPP] scale scores of 1 or 2 and ADHD-Rating Scale: Investigator Administered and Scored [ADHD-RS-I] score less than 50% of baseline score) with methylphenidate treatment alone and received combined treatment.. Investigator and parent ratings of ADHD symptoms, aggression, and global functioning improved significantly during both methylphenidate monotherapy treatment and during combined methylphenidate-quetiapine treatment. At the conclusion of combined treatment, 42% of the sample met all criteria for clinically significant improvement and 79% showed minimal aggression. Mild and transient sedation was reported by about half the cases. Weight loss (0.9 kg) during methylphenidate treatment was offset by weight gain (1.2 kg) during combination treatment.. Quetiapine addition to methylphenidate was effective in reducing ADHD and aggression in individuals who did not respond sufficiently (based on CGI-S, RAAPP, and ADHD-RS-I criteria for significant improvement) to OROS methylphenidate alone at a 54-mg/day dose.

The aim of this study was to compare the efficacy and tolerability of quetiapine and divalproex for the treatment of impulsivity and reactive aggression in adolescents with co-occurring bipolar disorder and disruptive behavior disorders.. Patients were included in this post hoc analysis if they scored > or = 14 on the Positive and Negative Syndrome Scale (PANSS) Excited Component (EC) and > or = 4 on at least one of the PANSS EC items, had a current diagnosis of bipolar I disorder, manic or mixed episode, and had a lifetime and/or current diagnosis of a disruptive behavioral disorder (DBD) [conduct disorder (CD) or oppositional defiant disorder (ODD)]. Thirty-three (92%) of the 36 subjects with bipolar disorder and DBD met the PANSS EC inclusion criteria. These thirty-three adolescents were randomized to quetiapine (400-600 mg/day) or divalproex (serum level 80-120 microg/mL) for 28 days in this double-blinded study. The primary efficacy measure was change in PANSS Excited Component (EC) score over the study period and at each time point.. Repeated measures analysis of variance (ANOVA) demonstrated statistically significant within-treatment-group effects for divalproex (baseline = 20.6, end point = 13.3, p < 0.0001) and quetiapine (baseline = 18.8, end point = 10.8, p < 0.0001) for the PANSS EC. There were no statistically significant treatment group differences in PANSS EC changes from baseline to end point scores (p = 0.7, d = 0.14). Mixed regression analyses (comparison of slopes, DAY*TREATMENT) revealed that there was no significant difference in the rate of improvement in the PANSS EC scores between the two treatment groups [F(1,31) = 0.78, p = 0.39, d = 0.28].. Quetiapine and divalproex showed similar efficacy for the treatment of impulsivity and reactive aggression related to co-occurring bipolar and disruptive behavior disorders in adolescents. Quetiapine and divalproex are both useful as monotherapy for the treatment of impulsivity and reactive aggression in adolescents with bipolar and disruptive behavior disorders. Placebo-controlled studies are necessary.

Radiopaque densities can be observed on imaging after the ingestion of either foreign bodies or some medications. Our case report discusses an 11-year-old boy with autism spectrum disorder and attention deficient disorder who presented to the emergency department because of concerns for constipation and dehydration. Incidentally, an abdominal x-ray showed numerous radiopaque densities throughout his intestines in addition to his constipation. He was admitted, and his home regimen was reviewed to attempt to identify a potential source for these radiopaque densities. This case presented an interesting teaching opportunity in the identification of the radiopaque densities and review of pharmacokinetics.

Lithium and quetiapine are known to be effective treatments for bipolar disorder. However, little information is available to inform prediction of response to these medications. Machine-learning methods can identify predictors of response by examining variables simultaneously. Further evaluation of models on a test sample can estimate how well these models would generalize to other samples.. Data (N = 482) were drawn from a randomized clinical trial of outpatients with bipolar I or II disorder who received adjunctive personalized treatment plus either lithium or quetiapine. Elastic net regularization (ENR) was used to generate models for lithium and quetiapine; these models were evaluated on a test set.. Predictions from the lithium model explained 17.4% of the variance in actual observed scores of patients who received lithium in the test set, while predictions from the quetiapine model explained 32.1% of the variance of patients that received quetiapine. Of the baseline variables selected, those with the largest parameter estimates were: severity of mania; attention-deficit/hyperactivity disorder (ADHD) comorbidity; nonsuicidal self-injurious behavior; employment; and comorbidity with each of two anxiety disorders (social phobia/society anxiety and agoraphobia). Predictive accuracy of the ENR model outperformed the simple and basic theoretical models.. ENR is an effective approach for building optimal and generalizable models. Variables identified through this methodology can inform future research on predictors of response to lithium and quetiapine, as well as future modeling efforts of treatment choice in bipolar disorder.

Antipsychotic medication use has steadily increased in Canada, with an expansion in the profile of users and the diagnoses for which they are used. The use of antipsychotics is associated with a number of adverse effects for which routine monitoring is recommended. The objectives of this study were to determine the most common diagnoses associated with antipsychotic use in children in Alberta, Canada and the proportion who receive recommended laboratory tests for adverse effects.. Data on dispensed antipsychotics, diagnoses, prescribers, and laboratory testing were obtained from provincial data sources. To assess the frequency of metabolic and hormonal laboratory baseline and/or follow-up testing, the sample was divided into an antipsychotic-naïve cohort and an antipsychotic non-naïve cohort.. In 2014, 6916 children were dispensed at least one second- or third-generation antipsychotic. The most frequently dispensed antipsychotics were risperidone (3908 children), quetiapine (2140 children), and aripiprazole (1302 children). The majority of children prescribed risperidone were diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) or conduct disorder. Quetiapine was mainly prescribed for neurotic disorder or depression, while aripiprazole was prescribed most frequently for conduct disorder or neurotic disorders. Among antipsychotic-naïve patients, 17% had at least one laboratory test done at baseline, and 35% had at least one laboratory test done at follow-up. In the non-naïve patients, 42% had at least one follow-up laboratory test. Lipid and glucose testing were done in less than 5% of the naïve cohort at baseline, and in less than 15% at follow-up. In the non-naïve cohort, less than 22% received lipid or glucose testing during the year 2014.. The majority of antipsychotic use in children in Alberta is off-label and associated with disruptive behavior disorders, depression, and anxiety disorders. The vast majority of children prescribed antipsychotic medications do not undergo recommended laboratory tests.

Priapism is the prolonged, painful erection of penile tissue not accompanied by sexual arousal. Priapism has been established as a rare adverse drug reaction to drugs such as antipsychotics, psychostimulants, antidepressants, and mood stabilizers. Immediate intervention is needed to prevent destructive and irreversible complications, such as erectile dysfunction, disfigurement, inability of the penis to stay erect, and related social/emotional problems. Antipsychotic-induced priapism may result from the alpha receptor occupancy property of those drugs. We report the case of a 13-year-old suffering from attention deficit-hyperactivity disorder plus conduct disorder with priapism related to antipsychotics. Episodes occurred with risperidone plus methylphenidate, quetiapine plus methylphenidate, and chlorpromazine alone.

An 18-year-old man diagnosed with attention-deficit hyperactivity disorder was recently started on quetiapine in addition to regular methylphenidate, which he had been taking for a number of years. He presented with chest pain and inferolateral ST elevation, and underwent urgent coronary angiography, which showed normal coronary arteries. The initial troponin level was raised and an inpatient echocardiogram showed mild left ventricular systolic dysfunction with no evidence of regional wall motion abnormality. Cardiac MRI showed subepicardial late gadolinium enhancement, which was suggestive of myocarditis. Quetiapine and methylphenidate were discontinued and the patient was discharged home after 1 week. He was followed up within 8 weeks with complete recovery and no symptoms.

Bipolar Disorders (BD) are often comorbid with disruptive behaviour disorders (DBDs) (oppositional-defiant disorder or conduct disorder), with negative implications on treatment strategy and outcome. The aim of this study was to assess the efficacy of quetiapine monotherapy in adolescents with BD comorbid with conduct disorder (CD). A consecutive series of 40 adolescents (24 males and 16 females, age range 12-18 years, mean age 14.9 ± 2.0 years), diagnosed with a clinical interview (Kiddie Schedule for Affective Disorders and Schizophrenia for School-Aged Children-Present and Lifetime Version [K-SADS-PL]) according to American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) criteria were included. All the patients were treated with quetiapine monotherapy (mean final dose 258 ± 124 mg/day, range 100-600 mg/day). At the end-point (3 months), 22 patients (55.0%) were responders (Clinical Global Impressions-Improvement [CGI-I] score of 1 or 2 and CGI-Severity [CGI-S] ≤ 3 and improvement of at least 30% Children's Global Assessment Scale [C-GAS] during 3 consecutive months). Both CGI-S and C-GAS significantly improved (p<0.0001). Nine out of the 16 patients with suicidality (56.3%) had a reduction in this severe symptom during the follow-up. Nonresponders were more frequently males, and more frequently had an attention-deficit/hyperactivity disorder (ADHD) comorbidity. Eight patients (20.0%) experienced moderate to severe sedation and eight (20.0%) experienced increased appetite and weight gain. In these severely impaired adolescents, quetiapine monotherapy was well tolerated and effective in>50% of the patients.

The aim of this study was to develop a parent-completed questionnaire measure of specific types of aggressive behaviors in children and adolescents.. Two studies tested the psychometrics of the Outburst Monitoring Scale (OMS), a questionnaire measure of verbal, property, self, and physical aggression, based in part on the categories of the Overt Aggression Scale. In Study 1, parents of 23 adolescents with a history of aggressive-disruptive behavior and 30 control adolescents completed the OMS and other measures of aggressive-disruptive behavior. In Study 2, parents of 9 adolescents with a history of aggressive-disruptive behavior completed the OMS and other measures of aggressive-disruptive behavior during open-label treatment with methylphenidate and quetiapine.. Results from both studies demonstrated adequate internal consistency of OMS subscale and total scores. OMS scores correlated significantly with measures of conduct disorder and oppositional defiant disorder and differentiated between control and aggressive sub-samples. Changes in OMS scores during treatment correlated with changes in other measures of aggressive and disruptive behavior.. The OMS demonstrated good internal consistency, strong correlations with other measures of aggressive/disruptive behavior, good differential validity, and sensitivity to change during a medication trial. The OMS offers a quick, valid, questionnaire-based alternative for measuring frequencies of specific aggressive behaviors in clinical and research settings.

Stimulants have been the mainstay of treatment for children with Attention-deficit/hyperactivity Disorder (ADHD). However, stimulants have been controversially purported to precipitate and exacerbate tics. Atomoxetine, a selective norepinephrine inhibitor, was introduced as a safe non-stimulant alternative treatment for ADHD children with comorbid tics or TS. We are presenting two children with ADHD, in which atomoxetine, at relatively low doses, exacerbated and precipitated tics. The diagnoses of ADHD and tic disorder were based on clinical observations and standardized rating scales. Case 1, an 8-year-old boy, had history of stimulant-induced tics. This child was placed on atomoxetine reported to be safe for patients with tics. This patient's tic control was adequate prior to atomoxetine treatment. However, while on atomoxetine, the patient promptly experienced tic exacerbation. Case 2, a 6-year-old boy, had no previous history of stimulant therapy and was receiving citalopram due to a comorbid anxiety disorder. Atomoxetine was initiated for the treatment of ADHD with improvement in the ADHD symptoms. But, upon a mild dose increase, the patient presented tic precipitation consisting primarily of neck twitches. Both cases experienced a decrease in tic activity when atomoxetine was discontinued, but tics did not fully resolve, causing psychosocial disturbance. Atypical neuroleptics were used with good results. Periodic assessments of the need for continued neuroleptic treatment were emphasized. These two children exemplify atomoxetine's potential to exacerbate and precipitate tics in children with ADHD. Independent controlled studies are needed to determine if atomoxetine should be used in children with ADHD and comorbid tic disorders or TS.

Two children with Tourette's syndrome and comorbid disorders were treated with quetiapine, an atypical antipsychotic successfully used in patients with psychoses and schizophrenia with low incidence of extrapyramidal side effects. Clinical observations and standardized rating scales suggested that this drug produced beneficial effects on tics and other symptoms. Adverse effects (at low doses) were minimal. Because it was suggested that tic efficacy of the newer antipsychotics was related to higher D2 occupancy (with the exception of quetiapine and clozapine, which have relatively low D2 activity), it is hypothesized that tic patients are D2 sensitive and need lower doses of medications. These children were treated naturalistically and were reported retrospectively because of their encouraging outcomes. However, these findings should be interpreted with caution, because no contrast groups, drug withdrawal, or placebo were utilized. Controlled studies are needed to determine the efficacy of quetiapine in the treatment of Tourette's syndrome.
