Trends in antipsychotic drug use by very young, privately insured children

Effects of Risperidone and Prenatal Poly I:C Exposure on GABAA Receptors and AKT-GSK3β Pathway in the Ventral Tegmental Area of Female Juvenile Rats

The ventral tegmental area (VTA) in the ventral midbrain is the origin of the dopaminergic neurotransmission pathways. Although GABA_A receptors and AKT-GSK3β signaling are involved in the pathophysiology of mental disorders and are modulated by antipsychotics, an unmet task is to reveal the pathological changes in these biomarkers and antipsychotic modulations in the VTA. Using a juvenile polyriboinosinic-polyribocytidylic acid (Poly I:C) psychiatric rat model, this study investigated the effects of adolescent risperidone treatment on GABA_A receptors and AKT/GSK3β in the VTA. Pregnant female Sprague-Dawley rats were administered Poly I:C (5mg/kg; i.p) or saline at gestational day 15. Juvenile female offspring received risperidone (0.9 mg/kg, twice per day) or a vehicle from postnatal day 35 for 25 days. Poly I:C offspring had significantly decreased mRNA expression of GABA_A receptor β3 subunits and glutamic acid decarboxylase (GAD2) in the VTA, while risperidone partially reversed the decreased GAD2 expression. Prenatal Poly I:C exposure led to increased expression of AKT2 and GSK3β. Risperidone decreased GABA_A receptor β2/3, but increased AKT2 mRNA expression in the VTA of healthy rats. This study suggests that Poly I:C-elicited maternal immune activation and risperidone differentially modulate GABAergic neurotransmission and AKT-GSK3β signaling in the VTA of adolescent rats.

Antipsychotic Medications for Low-Income Preschoolers: Long Duration and Psychotropic Medication Polypharmacy

OBJECTIVE

This study aimed to evaluate prescribing patterns of antipsychotic medication and factors that predict duration of use among low-income, preschool-age children.

METHODS

State Medicaid claims from 2012 to 2017 were used to identify antipsychotic medication use for children <6 years old. ICD-9 and ICD-10 codes were used to describe child diagnoses. Descriptive and multivariable analyses were used to determine patterns of antipsychotic medication use and factors that predicted duration of use.

RESULTS

In 2012, 316 children <6 years of age started an antipsychotic medication in a southeastern state. Most were non-Hispanic White (N=202, 64%) and boys (N=231, 73%). Diagnoses included attention-deficit hyperactivity disorder (N=288, 91%), neurodevelopmental disorders (N=208, 66%), anxiety and trauma-related diagnoses (N=202, 64%), and autism spectrum disorders (ASDs) (N=137, 43%). The mean±SD duration of exposure to antipsychotic medication for children in the cohort was 2.6±1.7 years, but 86 children (27%) had >4 years of exposure. Almost one-third (N=97, 31%) received polypharmacy of four or more medication classes, and 42% (N=131) received metabolic screening. Being male, being in foster care, and having a diagnosis of ASD or disruptive mood dysregulation disorder were significantly associated with duration of use of antipsychotic medications; race-ethnicity was not significantly associated with duration of use. Emergency department visits (N=277, 88%) and inpatient hospitalizations (N=107, 34%) were observed during the study period.

CONCLUSIONS

Many preschoolers received antipsychotic medications for substantial periods. Further research is needed to identify evidence-based practices to reduce medication use and improve outcomes.

Trends in Antipsychotic Medication Use in Young Privately Insured Children

OBJECTIVE

To estimate trends of annual antipsychotic medication use by privately insured young children (aged 2-7 years) in the United States, and to describe the clinical and treatment characteristics of these children.

METHOD

The study population included young children from a nationwide commercial claims database (2007-2017). We estimated annual antipsychotic use by age and sex, defined as the number of children dispensed an antipsychotic per year divided by the number enrolled. We described clinical diagnoses and mental health service use in those with prescription antipsychotic use in 2009 and 2017.

RESULTS

Annual antipsychotic use in young children was 0.27% in 2007, peaked at 0.29% in 2009, and statistically significantly declined to 0.17% by 2017 (linear trend: -0.017% per year, 95% CI: -0.018 to -0.016). Antipsychotic use was higher in boys than in girls. A greater proportion of antipsychotic users received a mental disorder diagnosis in 2017 (89%) than in 2009 (86%, p < .01). The most common clinical diagnoses in antipsychotic users, under a hierarchical classification, were pervasive developmental disorder (2009 = 27%, 2017 = 38%, p < .01), conduct or disruptive behavior disorder (2009 = 15%, 2017 = 21%, p < .01), and attention-deficit/hyperactivity disorder (2009 = 24%, 2017 = 18%, p < .01). Among 2017 antipsychotic users, 32% had 4+ psychotherapy claims, 43% had a psychiatrist visit, and the majority used another psychotropic medication, most commonly a stimulant (boys = 57%, girls = 50%).

CONCLUSION

In privately insured young children, antipsychotic use declined from 2009 to 2017, with shifts toward indications with some supporting evidence. Nevertheless, a majority of use remains off label and for conditions lacking effectiveness and safety data. Improving antipsychotic prescribing in young children remains a challenge.

Risperidone or Aripiprazole Can Resolve Autism Core Signs and Symptoms in Young Children: Case Study

Risperidone and aripiprazole are approved by the USA Food and Drug Administration for the treatment of irritability and aggression in children from the ages of 5 and 6 years, respectively. However, there are no approved medications for the treatment of autism spectrum disorder (ASD) core signs and symptoms. Nevertheless, early intervention is recognized as key to improving long-term outcomes. This retrospective case study included 10 children (mean age, 2 years 10 months) with ASD who presented with persistent irritability and aggression before 4 years of age that was unresponsive to behavioral interventions and sufficiently severe to consider pharmacological intervention with risperidone or aripiprazole combined with standard supportive therapies. Besides ameliorating comorbid behaviors, improvement was observed in ASD core signs and symptoms for all patients, with minimal-to-no symptoms observed in 60% of patients according to the Childhood Autism Rating Scale 2-Standard Test and Clinical Global Impression scales. Excessive weight gain in two patients was the only adverse effect observed that required intervention. This is the first study to suggest that ASD can potentially be treated in very young children (<4 years). Clinical trials are urgently required to validate these findings among this pediatric population.

Safer use of antipsychotics in youth (SUAY) pragmatic trial protocol

BACKGROUND

Programs such as the Pediatric Access Line in Washington state have shown decreases in antipsychotic medication use by youth with non-psychotic disorders. Program outcomes have been studied with observational designs. This manuscript describes the protocol for Targeted and Safer Use of Antipsychotics in Youth (SUAY), a randomized controlled trial of psychiatrist review of prescriptions and facilitated access to psychosocial care. The aim of the intervention is to reduce the number of person-days of antipsychotic use among participants.

METHODS

Recruitment occurs at 4 health systems. Targeted enrollment is 800 youth aged 3-17 years. Clinicians are block randomized to intervention versus usual care prior to the study. Youth are nested within the arm of the prescribing clinician. Clinicians in the intervention group receive an EHR-based best practice alert with options to expedite access to psychosocial care and all medication orders are reviewed by a child and adolescent psychiatrist with feedback provided to the prescriber. The primary outcome is person-days of antipsychotic medication use in the 6 months following the initial order. All randomized individuals contribute data regardless of their level of participation (including declining all services).

DISCUSSION

The trial has been approved by the institutional review boards at each of the 4 sites. The intervention has 4 novel design features including automated recruitment using a best practice alert, psychiatrist medication order review and consultation, telephone navigation to psychosocial care, and telemental health visits. Recruitment began in March of 2018 and will be completed in June 2020. Follow-up will be completed December 31, 2020.

Risperidone-Induced Obesity in Children and Adolescents With Autism Spectrum Disorder: Genetic and Clinical Risk Factors

Aims: Obesity is a significant problem for patients taking atypical antipsychotics. There were two aims of our study. The first aim was to compare the prevalence of overweight and obesity between children and adolescents with autism spectrum disorder (ASD) treated with risperidone with the general pediatric population. The second aim was to investigate the association of the HTR2C -759C>T, ABCB1 1236C>T, ABCB1 2677G>T/A, and ABCB1 3435C>T polymorphisms with risperidone-induced overweight and obesity in children and adolescents with ASD. Methods: Body weight and height were measured in 134 subjects. Overweight and obesity in children and adolescents were classified using the International Obesity Task Force (IOTF) criteria. Genotyping was performed by TaqMan real-time polymerase chain reaction (PCR). Results: Our study found that the prevalence of overweight and obesity was significantly higher in children and adolescents with ASD treated with risperidone compared with healthy individuals (p = 0.01 and p = 0.002). The genetic polymorphisms of HTR2C -759C>T, ABCB1 1236C>T, ABCB1 2677G>T/A, and ABCB1 3435C>T were not associated with overweight/obesity in children and adolescents with ASD treated with risperidone after adjustment for multiple comparisons by the method of Bonferroni. Additionally, haplotype analysis revealed that there was no significant association between ABCB1 3435T-2677T/A-1236T haplotype and overweight/obesity. In multivariate logistic regression, after adjustment by the Bonferroni correction, there was only the duration of risperidone treatment that was significantly associated with overweight/obesity in children and adolescents with ASD. Conclusions: The findings suggest that children and adolescents with ASD treated with risperidone are at a higher risk of obesity, especially patients with extended treatment with risperidone. For the pharmacogenetic factors, -759C>T polymorphism of HTR2C gene and 1236C>T, 2677G>T/A, and 3435C>T polymorphisms of ABCB1 gene were not likely to be associated with the susceptibility to overweight/obesity in children and adolescents treated with risperidone. Due to the small sample size, further studies with a larger independent group are needed to confirm these findings.

Differences in Utilization of Mental Health Treatment Among Children and Adolescents With Medicaid or Private Insurance

OBJECTIVE

Children and adolescents with diagnosed mental disorders may require developmentally tailored interventions. However, little is known about the difference in mental health treatment utilization among children by age group and health insurance coverage.

METHODS

Using the 2016 MarketScan database, the study examined treatment utilization patterns by health insurance coverage (private and Medicaid) and developmental age group (preschool-age children, ages 3-5; young children, ages 6-11; and adolescents, ages 12-17).

RESULTS

Psychiatric medication only was the most common form of treatment utilization among all children, regardless of developmental age group or insurance coverage. Specifically, psychiatric medication only was received by 38% of preschool-aged children with Medicaid and 42% of those with private insurance, 43% of young children with Medicaid and 39% of those with private insurance, and 55% of adolescents with Medicaid and 49% of those with private insurance.

CONCLUSIONS

Given that evidence-based practices suggest that combined treatment with psychiatric medications and psychotherapy may be the recommended treatment, the study's findings raise potential concerns about the high use of medication-only treatment.

A Randomized Controlled Trial of Parent-Child Psychotherapy Targeting Emotion Development for Early Childhood Depression

OBJECTIVE

Clinical depression in children as young as age 3 has been validated, and prevalence rates are similar to the school-age disorder. Homotypic continuity between early and later childhood depression has been observed, with alterations in brain function and structure similar to those reported in depressed adults. These findings highlight the importance of identifying and treating depression as early as developmentally possible, given the relative treatment resistance and small effect sizes for treatments later in life. The authors conducted a randomized controlled trial of a dyadic parent-child psycho-therapy for early childhood depression that focuses on enhancing the child's emotional competence and emotion regulation.

METHOD

A modified version of the empirically tested parent-child interaction therapy with a novel "emotion development" module (PCIT-ED) was compared with a waiting list condition in a randomized controlled trial in 229 parent-child dyads with children 3-6.11 years of age. Both study arms lasted 18 weeks.

RESULTS

Children in the PCIT-ED group had lower rates of depression (primary outcome), lower depression severity, and lower impairment compared with those in the waiting list condition (Cohen's d values, >1.0). Measures of child emotional functioning and parenting stress and depression were significantly improved in the PCIT-ED group.

CONCLUSIONS

The findings from this randomized controlled trial of a parent-child psychotherapy for early childhood depression suggest that earlier identification and intervention in this chronic and relapsing disorder represents a key new pathway for more effective treatment. Manualized PCIT-ED, administered by master's-level clinicians, is feasible for delivery in community health settings.

Methylphenidate and atomoxetine prescribing trends in children in the Western Cape Province of South Africa, 2005-2013

Background

There is paucity of data on methylphenidate and atomoxetine prescribing patterns in South African children.

Aim

To describe the prescribing trends of these agents in children residing in the Western Cape Province.

Setting

South African private health sector.

Methods

Longitudinal drug utilisation study on medicine claims data from 2005–2013, focussing on the number of patients and prescriptions per patient.

Results

The total number of patients increased by 29.5% from 2005 to 2013. The majority were boys (male:female ratio, 3.5:1), and between the ages of > 6 and ≤12 years in 2005 and >12 and ≤18 years in 2013. More than 75% of patients received methylphenidate or atomoxetine in the City of Cape Town Metropolitan municipality. Prescriptions for methylphenidate and atomoxetine increased by 45.5% overall from 2005 to 2013 (p < 0.001), with that for methylphenidate and atomoxetine increasing by 36.0% and 314.5%, respectively. The average number of annual methylphenidate prescriptions per patient increased from 3.96 ± 2.92 (95% CI, 3.69–4.23) in 2005 to 4.38 ± 2.85 (95% CI, 4.14–4.61) in 2013 (Cohen’s d = 0.14) and for atomoxetine from 2.58 ± 1.86 (95% CI, 1.80–3.37) in 2005 to 4.85 ± 3.66 (95% CI, 3.84–5.86) in 2013 (Cohen’s d = 0.62).

Conclusion

Although the total number of patients and prescribing of methylphenidate and atomoxetine increased significantly from 2005 to 2013, a slight downward trend was observed in the mean number of prescriptions per patient per year from 2008 onwards. These prescribing patterns warrant further research.

Early antipsychotic treatment in juvenile rats elicits long-term alterations to the adult serotonin receptors

BACKGROUND

Antipsychotic drug (APD) prescription/use in children has increased significantly worldwide, despite limited insight into potential long-term effects of treatment on adult brain functioning. While initial long-term studies have uncovered alterations to behaviors following early APD treatment, further investigations into potential changes to receptor density levels of related neurotransmitter (NT) systems are required.

METHODS

The current investigation utilized an animal model for early APD treatment with aripiprazole, olanzapine, and risperidone in male and female juvenile rats to investigate potential long-term changes to the adult serotonin (5-HT) NT system. Levels of 5-HT1A, 5-HT2A, and 5-HT2C receptors were measured in the prefrontal cortex (PFC), caudate putamen (CPu), nucleus accumbens (NAc), and hippocampus via Western Blot and receptor autoradiography.

RESULTS

In the male cohort, long-term changes to 5-HT2A and 5-HT2C receptors were found mostly across hippocampal and cortical brain regions following early aripiprazole and olanzapine treatment, while early risperidone treatment changed 5-HT1A receptor levels in the NAc and PFC. Lesser effects were uncovered in the female cohort with aripiprazole, olanzapine and risperidone to alter 5-HT1A and 5-HT2A receptors in NAc and hippocampal brain regions, respectively.

CONCLUSION

The results of this study suggest that early treatment of various APDs in juvenile rats may cause gender and brain regional specific changes in 5-HT2A and 5-HT2C receptors in the adult brain.

National Patterns of Commonly Prescribed Psychotropic Medications to Young People

OBJECTIVE

To describe national annual prescribing patterns of stimulant, antidepressant, and antipsychotic medications to young people.

METHODS

Prescriptions for three commonly prescribed psychotropic classes (stimulants, antidepressants, and antipsychotics) to young people aged 3-24 years were analyzed from the IMS LifeLink LRx National Longitudinal Prescription database (n = 6,351,482). Denominators were adjusted to generalize estimates to the U.S.

POPULATION

Comparisons are presented of percentages filling ≥1 prescription of each medication class during the study year stratified by patient sex, age, and prescriber specialty.

RESULTS

The total annual percentage of prescriptions filled by youth for any of the three medication classes was by age 3-5 years (0.8%), 6-12 years (5.4%), 13-18 years (7.7%), and 19-24 years (6.0%). Stimulant use was highest for older children (age 11 = 5.7%). Antidepressant use tended to increase with age and was highest for young adults (age 24 = 4.8%). Annual antipsychotic prescription percentages were lower than antidepressant or stimulant percentages for all age groups, with a peak in adolescence (age 16 = 1.3%). Annual stimulant and antipsychotic percentages for males were higher than corresponding percentages for females, but converged for young adults. Psychiatrists and child psychiatrists accounted for most of the prescriptions of antidepressants (22.2%-53.2%) and antipsychotics (51.7%-70%), but fewer of the stimulant prescriptions (30.4%-36.2%).

CONCLUSIONS

The age and sex distribution of stimulants and antidepressants among young people is broadly consistent with known epidemiologic patterns of their established indications for attention-deficit/hyperactivity disorder, anxiety, and depression. The pattern of antipsychotics may reflect the heterogeneity of disorders and conditions treated with this medication class.

Providers' Behaviors and Beliefs on Prescribing Antipsychotic Medication to Children: A Qualitative Study

Fragmentation in behavioral and mental health care to children has resulted in suboptimal care and high rates of psychotropic medication use, especially antipsychotic medications (APM). A qualitative study, based on the Theory of Planned Behavior (TPB), aimed to better understand prescribing practices, barriers to optimal treatment, and potential interventions to safeguard the use of APM for children in Kentucky. The most common barrier to optimal care was access to mental health specialists. Social norms and pressure from families contribute to increased medication use. We identify promising interventions to safeguard the use of APM through the lens of the TPB.

Antipsychotic Polypharmacy among Children and Young Adults in Office-Based or Hospital Outpatient Department Settings

The purpose of the study was three-fold: (1) to estimate the national trends in antipsychotic (AP) polypharmacy among 6- to 24-year-old patients in the U.S.; (2) to identify frequently used AP agents and mental disorder diagnoses related to AP polypharmacy; and (3) to assess the strength of association between AP polypharmacy and patient/provider characteristics. We used publicly available ambulatory health care datasets to evaluate AP polypharmacy in office-based or hospital outpatient department settings to conduct a cross-sectional study. First, national visit rates between 2007 and 2011 were estimated using sampling weights. Second, common diagnoses and drugs used in AP polypharmacy were identified. Third, a multivariate logistic regression model was developed to assess the strength of association between AP polypharmacy and patient and provider characteristics. Between 2007 and 2011, approximately 2% of office-based or hospital outpatient department visits made by 6- to 24-year-old patients included one or more AP prescriptions. Of these visits, 5% were classified as AP polypharmacy. The most common combination of AP polypharmacy was to use two or more second-generation APs. Also, bipolar disorder and schizophrenia were the two most frequent primary mental disorder diagnoses among AP polypharmacy visits. The factors associated with AP polypharmacy were: older age (young adults), black, having one or more non-AP prescriptions, and having schizophrenia or ADHD.

Delayed yet persistent effects of daily risperidone on activity in developing rats

Early-life administration of risperidone, the most widely used antipsychotic drug in children, leads to persistently elevated locomotor activity in adult rats. This study determined whether and when elevated locomotor activity emerges during developmental risperidone administration. Developing and adult rats were administered daily injections of risperidone (1.0 and 3.0 mg/kg) or vehicle for 4 weeks beginning at postnatal days 14 and 74, respectively. Starting with the first injection and every 7 days thereafter, locomotor activity was measured immediately after the injection and 20 min before the next day's injection. Activity was also recorded 1 week after the final injection. Risperidone markedly decreased locomotor activity in developing and adult rats immediately after injection. Within 24 h after their first injection, adult rats administered risperidone showed greater activity levels. In contrast, developing rats did not show compensatory hyperactivity until the beginning of the fourth week of risperidone administration. One week after the final risperidone injection, there was no evidence of hyperactivity in the adult rats maintained on risperidone, but developing rats administered risperidone, especially females, showed greater activity levels relative to vehicle-administered controls. In comparison with adult rats, the emergence of compensatory hyperactivity during long-term antipsychotic drug administration is delayed in developing rats, but persists after treatment cessation.

Physical Health Outcomes in Preschoolers with Prior Authorization for Antipsychotics

OBJECTIVE

To examine incidence of adverse health outcomes and associated factors among preschoolers (under age 6) who received antipsychotic treatment through the Florida Medicaid Prior Authorization (PA) program.

METHODS

Using Florida's PA registry linked to the state's Medicaid claims data, we ascertained incident outcomes during PA-approved antipsychotic use between April 2008 and September 2015 (7.5 years). Six outcomes associated with use of antipsychotics included: diabetes, obesity, hyperlipidemia, hyperprolactinemia, cardiovascular disease (CVD) (including hypertension, ventricular arrhythmia, and other CVDs), and extrapyramidal symptoms (EPS) (including dystonia, akathisia, parkinsonism, and tardive dyskinesia). Outcome-specific incidences were stratified by short-term (≤1 year) and long-term (>1-7 years) antipsychotic use. We used multivariate modified Poisson regressions to determine factors associated with these outcomes among preschoolers.

RESULTS

The overall crude incidence during PA-approved antipsychotic use was highest for EPS and obesity (57 and 19 cases/1000 children-years, respectively). The rate of these two outcomes differed by duration of antipsychotic use. We observed a higher obesity (23.8 vs. 9.6, p < 0.001) and dystonia incidence (7.2 vs. 2.5, p < 0.05), but lower akathisia incidence (44.4 vs. 60.6, p < 0.05) among long-term antipsychotic users compared with short-term users. Five outcomes-ventricular arrhythmia, other cardiovascular side effects, hyperprolactinemia, parkinsonism, and tardive dyskinesia-occurred rarely (<2.0/1000 children-years). Preschoolers who were younger at baseline (≤2 years old vs. 4-5 years old) and Black (vs. White) were at a higher risk of EPS.

CONCLUSION

Risk for EPS and obesity deserves clinical attention during antipsychotic treatment among preschoolers. Controlled studies that allow interpretation of these incidence rates in the context of background risk and that formally quantify the incremental risk associated with antipsychotic initiation during early childhood are needed.

A case of a four-year-old child adopted at eight months with unusual mood patterns and significant polypharmacy

BACKGROUND

Long-term effects of neglect in early life are still widely unknown. Diversity of outcomes can be explained by differences in genetic risk, epigenetics, prenatal factors, exposure to stress and/or substances, and parent-child interactions. Very common sub-threshold presentations of children with history of early trauma are challenging not only to diagnose but also in treatment.

CASE PRESENTATION

A Caucasian 4-year-old, adopted at 8 months, male patient with early history of neglect presented to pediatrician with symptoms of behavioral dyscontrol, emotional dysregulation, anxiety, hyperactivity and inattention, obsessions with food, and attachment issues. He was subsequently seen by two different child psychiatrists. Pharmacotherapy treatment attempted included guanfacine, fluoxetine and amphetamine salts as well as quetiapine, aripiprazole and thioridazine without much improvement. Risperidone initiated by primary care seemed to help with his symptoms of dyscontrol initially but later the dose had to be escalated to 6 mg total for the same result. After an episode of significant aggression, the patient was admitted to inpatient child psychiatric unit for stabilization and taper of the medicine.

CONCLUSIONS

The case illustrates difficulties in management of children with early history of neglect. A particular danger in this patient population is polypharmacy, which is often used to manage transdiagnostic symptoms that significantly impacts functioning with long term consequences.

A National Profile of Attention-Deficit Hyperactivity Disorder Diagnosis and Treatment Among US Children Aged 2 to 5 Years

OBJECTIVE

Clinical guidelines provide recommendations for diagnosis and treatment of attention-deficit hyperactivity disorder (ADHD), with specific guidance on caring for children younger than 6 years. This exploratory study describes ADHD diagnosis and treatment patterns among young children in the United States using 2 nationally representative parent surveys.

METHODS

The National Survey of Children's Health (2007-2008, 2011-2012) was used to produce weighted prevalence estimates of current ADHD and ADHD medication treatment among US children aged 2 to 5 years. The National Survey of Children with Special Health Care Needs (2009-2010) provided additional estimates on types of medication treatment and receipt of behavioral treatment among young children with special health care needs (CSHCN) with ADHD.

RESULTS

In 2011 to 2012, 1.5% of young children (approximately 237,000) had current ADHD compared to 1.0% in 2007 to 2008. In 2011 to 2012, 43.7% of young children with current ADHD were taking medication for ADHD (approximately 104,000). In young CSHCN with ADHD, central nervous system stimulants were the most common medication type used to treat ADHD, and 52.8% of young CSHCN with current ADHD had received behavioral treatment for ADHD in the past year.

CONCLUSION

Nearly a quarter million In young CSHCN have current ADHD, with a prevalence that has increased by 57% from 2007 to 2008 to 2011 to 2012. The demographic patterns of diagnosis and treatment described in this study can serve as a benchmark to monitor service use patterns of young children diagnosed with ADHD over time.

Atypical antipsychotics for disruptive behaviour disorders in children and youths

BACKGROUND

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.

OBJECTIVES

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.

SEARCH METHODS

In January 2017, we searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers.

SELECTION CRITERIA

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.

DATA COLLECTION AND ANALYSIS

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.

MAIN RESULTS

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 with stimulants, since the latter can have a counteracting effect on weight gain due to appetite suppression. Pooling two trials with risperidone only (138 participants), we found that participants on risperidone gained 2.37 kilograms (kg) more (95% CI 0.26 to 4.49; moderate-quality evidence) than those on placebo. When we added a trial where all participants received a combination of risperidone and stimulants, we found that those on the combined treatment gained 2.14 kg more (95% CI 1.04 to 3.23; 3 studies; 305 participants; low-quality evidence) than those on placebo. Secondary outcomesOut of the 10 included trials, three examined general functioning, social functioning and parent satisfaction. No trials examined family or school functioning. Data on non-compliance/attrition rate and other adverse events were available from all 10 trials.

AUTHORS' CONCLUSIONS

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.

Early-life risperidone enhances locomotor responses to amphetamine during adulthood

Antipsychotic drug prescriptions for pediatric populations have increased over the past 20 years, particularly the use of atypical antipsychotic drugs such as risperidone. Most antipsychotic drugs target forebrain dopamine systems, and early-life antipsychotic drug exposure could conceivably reset forebrain neurotransmitter function in a permanent manner that persists into adulthood. This study determined whether chronic risperidone administration during development modified locomotor responses to the dopamine/norepinephrine agonist, D-amphetamine, in adult rats. Thirty-five male Long-Evans rats received an injection of one of four doses of risperidone (vehicle, .3, 1.0, 3.0mg/kg) each day from postnatal day 14 through 42. Locomotor activity was measured for 1h on postnatal days 46 and 47, and then for 24h once a week over the next two weeks. Beginning on postnatal day 75, rats received one of four doses of amphetamine (saline, .3, 1.0, 3.0mg/kg) once a week for four weeks. Locomotor activity was measured for 27h after amphetamine injection. Rats administered risperidone early in life demonstrated increased activity during the 1 and 24h test sessions conducted prior to postnatal day 75. Taking into account baseline group differences, these same rats exhibited significantly more locomotor activity in response to the moderate dose of amphetamine relative to controls. These results suggest that early-life treatment with atypical antipsychotic drugs, like risperidone, permanently alters forebrain catecholamine function and increases sensitivity to drugs that target such function.

Evidence-based treatments for youths with severely dysregulated mood: a qualitative systematic review of trials for SMD and DMDD

The aim of this literature review was to examine the evidence for psychotherapeutic and pharmacological treatments in subjects with severely dysregulated mood and to identify potential areas for improvements in research designs. A literature search was conducted using several databases for published (PubMed, PsycINFO) and ongoing (clinical trial registries) studies conducted in youths who met NIMH's criteria for Severe Mood Dysregulation (SMD) or the DSM-5 diagnosis of Disruptive Mood Dysregulation Disorder (DMDD). Eight completed studies were identified: three randomized trials, four open pilot studies and one case report. Seven ongoing studies were found in trial registries. The available evidence suggests potential efficacy of psychotherapies which have previously been developed for internalizing and externalizing disorders. The two main pharmacological strategies tested are, first, a monotherapy of psychostimulant or atypical antipsychotic such as risperidone, already used in the treatment of severe irritability in youths with developmental disorders; and second, the use of a serotonergic antidepressant as an add-on therapy in youths treated with psychostimulant. Ongoing studies will further clarify the effectiveness of psychotherapeutic interventions for DMDD individuals and whether they should be given alone or in conjunction with other treatments. The short duration of the trials for a chronic disorder, the low number of studies, the lack of placebo or active comparator arm, and restrictive inclusion criteria in most of the controlled trials dramatically limit the interpretation of the results. Finally, future research should be conducted across multiple sites, with standardized procedures to measure DMDD symptoms reduction, and include a run-in period to limit placebo effect.

Metabolic monitoring in children 5 years of age and younger prescribed second-generation antipsychotic medications

INTRODUCTION

The objective of this article was to identify the rates of patients ≤5 years of age who received recommended monitoring before and after second-generation antipsychotic (SGA) initiation and had an SGA metabolic adverse effect (MAE).

METHODS

This was a retrospective cohort analysis conducted at Kaiser Permanente Colorado, an integrated health care delivery system, between January 1, 2002, and June 30, 2011. Commercially insured patients ≤5 years of age newly initiated on an SGA were included. Patients were followed for up to 3 years. Metabolic monitoring included lipid profile, blood glucose, blood pressure, and weight measurements. Patient characteristics and outcomes were described using descriptive statistics.

RESULTS

A total of 40 patients were included. Overall, 2 (5.0%) patients received all recommended baseline monitoring, and no (0.0%) patients received all recommended follow-up monitoring. Weight monitoring was completed most frequently with rates of completion of 57.5%, 95.0%, 85.0%, and 76.5% at baseline and years 1, 2, and 3, respectively. At least 1 MAE was identified in 14/40 (35.0%), 5/28 (17.9%), and 2/17 (11.8%) patients during years 1, 2, and 3, respectively. The most frequent MAE identified was weight gain. Among patients identified with at least 1 MAE, 4/14 (28.6%), 2/5 (40.0%), and 2/2 (100%) received a behavioral intervention during years 1, 2, and 3, respectively.

DISCUSSION

Overall, baseline and follow-up metabolic monitoring were poor. Future studies should focus on examining barriers to monitoring in order to improve health care quality.

Patterns of Antipsychotic Prescribing by Physicians to Young Children

OBJECTIVE

Antipsychotic use among young children has grown rapidly despite a lack of approval by the U.S. Food and Drug Administration (FDA) for broad use in this age group. Characteristics of physicians who prescribed antipsychotics to young children were identified, and prescribing patterns involving young children and adults were compared.

METHODS

Physician-level prescribing data from IMS Health's Xponent database were linked with American Medical Association Masterfile data and analyzed. The sample included all U.S. psychiatrists and a random sample of 5% of family medicine physicians who wrote at least ten antipsychotic prescriptions per year from 2008 to 2011 (N=31,713). Logistic and hierarchical binomial regression models were estimated to examine physician prescribing for children ages zero to nine, and the types and numbers of ingredients used for children versus adults ages 20 to 64 were compared.

RESULTS

Among antipsychotic prescribers, 42.2% had written at least one antipsychotic prescription for young children. Such prescribing was more likely among physicians age ≤39 versus ≥60 (odds ratio [OR]=1.70) and physicians in rural versus nonrural areas (OR=1.11) and was less likely among males (OR=.93) and graduates of a top-25 versus a lower-ranked U.S. medical school (OR=.87). Among physicians who prescribed antipsychotics to young children and adults, 75.0% of prescriptions for children and 35.7% of those for adults were for drugs with an FDA-approved indication for that age. Fewer antipsychotic agents were prescribed for young children (median=2) versus adults (median=7).

CONCLUSIONS

Prescribing antipsychotics for young children was relatively common, but prescribing patterns differed between young children and adults.

Early Antipsychotic Treatment in Juvenile Rats Elicits Long-Term Alterations to the Dopamine Neurotransmitter System

Prescription of antipsychotic drugs (APDs) to children has substantially increased in recent years. Whilst current investigations into potential long-term effects have uncovered some alterations to adult behaviours, further investigations into potential changes to neurotransmitter systems are required. The current study investigated potential long-term changes to the adult dopamine (DA) system following aripiprazole, olanzapine and risperidone treatment in female and male juvenile rats. Levels of tyrosine hydroxylase (TH), phosphorylated-TH (p-TH), dopamine active transporter (DAT), and D₁ and D₂ receptors were measured via Western blot and/or receptor autoradiography. Aripiprazole decreased TH and D₁ receptor levels in the ventral tegmental area (VTA) and p-TH levels in the prefrontal cortex (PFC) of females, whilst TH levels decreased in the PFC of males. Olanzapine decreased PFC p-TH levels and increased D₂ receptor expression in the PFC and nucleus accumbens (NAc) in females only. Additionally, risperidone treatment increased D₁ receptor levels in the hippocampus of females, whilst, in males, p-TH levels increased in the PFC and hippocampus, D₁ receptor expression decreased in the NAc, and DAT levels decreased in the caudate putamen (CPu), and elevated in the VTA. These results suggest that early treatment with various APDs can cause different long-term alterations in the adult brain, across both treatment groups and genders.

Olanzapine Treatment of Adolescent Rats Alters Adult D2 Modulation of Cortical Inputs to the Ventral Striatum

BACKGROUND

The striatal dopamine system undergoes vast ontogenetic changes during adolescence, making the brain vulnerable to drug treatments that target this class of neurotransmitters. Atypical antipsychotic drugs are often prescribed to children and adolescents for off-label treatment of neuropsychiatric disorders, yet the long-term impact this treatment has on brain development remains largely unknown.

METHODS

Adolescent male rats were treated with olanzapine or vehicle for 3 weeks (during postnatal day 28-49) using a dosing condition designed to approximate closely D2 receptor occupancies in the human therapeutic range. We assessed D2 receptor modulation of corticostriatal inputs onto medium spiny neurons in the adult ventral striatum using in vitro whole-cell current clamp recordings.

RESULTS

The D2/D3 agonist quinpirole (5 µM) enhanced cortically driven medium spiny neuron synaptic responses in slices taken from adult rats treated with vehicle during adolescence, as in untreated adult rats. However, in slices from mature rats treated with olanzapine during adolescence, quinpirole reduced medium spiny neuron activation. The magnitude of decrease was similar to previous observations in untreated, prepubertal rats. These changes may reflect alterations in local inhibitory circuitry, as the GABA-A antagonist picrotoxin (100 µM) reversed the effects of quinpirole in vehicle-treated slices but had no impact on cortically evoked responses in olanzapine-treated slices.

CONCLUSIONS

These data suggest that adolescent atypical antipsychotic drug treatment leads to enduring changes in dopamine modulation of corticostriatal synaptic function.

The Effectiveness and Tolerability of Central Nervous System Stimulants in School-Age Children with Attention-Deficit/Hyperactivity Disorder and Disruptive Mood Dysregulation Disorder Across Home and School

OBJECTIVE

This study examines the effectiveness and tolerability of stimulants in children with attention-deficit/hyperactivity disorder (ADHD) and disruptive mood dysregulation disorder (DMDD).

METHODS

To be eligible, participants had to meet Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV) criteria for the combined subtype of ADHD and National Institute of Mental Health (NIMH) severe mood dysregulation criteria. The Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-V) DMDD criteria were retrospectively assessed after the study was completed. An open-label medication trial lasting up to 6 weeks was completed to optimize the central nervous system (CNS) stimulant dose. Measures of affective symptoms, ADHD symptoms and other disruptive behaviors, impairment, and structured side effect ratings were collected before and after the medication trial.

RESULTS

Optimization of stimulant medication was associated with a significant decline in depressive symptoms on the Childhood Depression Rating Score-Revised Scale (p<0.05, Cohen's d=0.61) and Mood Severity Index score (p<0.05, Cohen's d=0.55), but not in manic-like symptoms on the Young Mania Rating Scale. There was a significant reduction in ADHD (p<0.05, Cohen's d=0.95), oppositional defiant disorder (ODD) (p<0.05, Cohen's d=0.5), and conduct disorder (CD) symptoms (p<0.05, Cohen's d=0.65) as rated by parents. There was also a significant reduction in teacher-rated ADHD (p<0.05, Cohen's d=0.33) but not in ODD symptoms. Medications were well tolerated and there was no increase in side effect ratings seen with dose optimization. Significant improvement in functioning was reported by clinicians and parents (all p's<0.05), but youth still manifested appreciable impairment at end-point.

CONCLUSIONS

CNS simulants were well tolerated by children with ADHD comorbid with a diagnosis of DMDD. CNS stimulants were associated with clinically significant reductions in externalizing symptoms, along with smaller improvements in mood. However, most participants still exhibited significant impairment, suggesting that additional treatments may be needed to optimize functioning.

Comparison of the effects of methylphenidate and the combination of methylphenidate and risperidone in preschool children with attention-deficit hyperactivity disorder

Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder among preschool children but the number of controlled clinical trials regarding psychopharmacological treatment in this age group is limited. The aim of this study was to compare methylphenidate with the combination of methylphenidate and risperidone in preschool children with ADHD. Forty-two preschool children, aged 3–6 years, diagnosed with ADHD by a child and adolescent psychiatrist according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition-Text Revision criteria, were enrolled in a 6-week, single-blind clinical trial and administered with methylphenidate (5–30 mg/dl) or the combination of methylphenidate and risperidone (0.25–2 mg/dl) in Iran. Treatment outcomes were assessed using the Conners' Rating Scale and Clinical Global Impression (CGI) Scale at baseline and 3 and 6 weeks after starting the drugs administration. Side effects were rated by a checklist and body weight was measured at each visit. There were no significant differences between the two protocols in Parent Conners' Rating Scale scores (P > 0.05) and CGI scores (P > 0.05). Both groups showed a significant improvement in ADHD symptoms over the 6 weeks of treatment for Parent Conners' Rating Scale (P < 0.001). The combination group used significantly lower doses of methylphenidate compared to the other group (P = 0.002). The most common adverse effects were anorexia (21.7%) and daytime drowsiness (17.4%) in combination treatment group and insomnia (33.3%) and anorexia (25%) in methylphenidate group. Risperidone and methylphenidate may be effective and well tolerated in preschool children with ADHD, and adding risperidone to methylphenidate may decrease the occurrence of some side effects of methylphenidate such as insomnia and anorexia and lower the dose of methylphenidate may be needed to control symptoms.

Use of the second-generation antipsychotic, risperidone, and secondary weight gain are associated with an altered gut microbiota in children

The atypical antipsychotic risperidone (RSP) is often associated with weight gain and cardiometabolic side effects. The mechanisms for these adverse events are poorly understood and, undoubtedly, multifactorial in etiology. In light of growing evidence implicating the gut microbiome in the host's energy regulation and in xenobiotic metabolism, we hypothesized that RSP treatment would be associated with changes in the gut microbiome in children and adolescents. Thus, the impact of chronic (>12 months) and short-term use of RSP on the gut microbiome of pediatric psychiatrically ill male participants was examined in a cross-sectional and prospective (up to 10 months) design, respectively. Chronic treatment with RSP was associated with an increase in body mass index (BMI) and a significantly lower ratio of Bacteroidetes:Firmicutes as compared with antipsychotic-naïve psychiatric controls (ratio=0.15 vs 1.24, respectively; P<0.05). Furthermore, a longitudinal observation, beginning shortly after onset of RSP treatment, revealed a gradual decrease in the Bacteroidetes:Firmicutes ratio over the ensuing months of treatment, in association with BMI gain. Lastly, metagenomic analyses were performed based on extrapolation from 16S ribosomal RNA data using the software package, Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt). Those data indicate that gut microbiota dominating the RSP-treated participants are enriched for pathways that have been implicated in weight gain, such as short-chain fatty acid production.

Increased Risk of Obesity and Metabolic Dysregulation Following 12 Months of Second-Generation Antipsychotic Treatment in Children: A Prospective Cohort Study

OBJECTIVE

To determine the risk of developing obesity and related metabolic complications in children following long-term treatment with risperidone or quetiapine.

METHODS

This was a 1-year naturalistic longitudinal study conducted between February 2009 and March 2012. A total of 130 children aged 2 to 18 years without prior exposure to second-generation antipsychotics (SGAs) were enrolled at initiation of treatment with either risperidone or quetiapine. Metabolic parameters were measured at baseline and months 6 and 12. Data of 37 participants (20 treated with risperidone and 17 treated with quetiapine) who completed 12-month monitoring were used in the analysis.

RESULTS

After 1 year of SGA treatment, mean weight increased significantly by 10.8 kg (95% CI 7.9 kg to 13.7 kg) for risperidone and 9.7 kg (95% CI 6.5 kg to 12.8 kg) for quetiapine. Body mass index z score also increased significantly in both groups (P < 0.001). There was a high incidence of children becoming overweight or obese (6/15 [40.0%] for risperidone-treated and 7/14 [50.0%] for quetiapine-treated). The mean levels of fasting glucose (for risperidone-treated) and ratio of total cholesterol to high-density lipoprotein cholesterol (for quetiapine-treated) increased significantly by 0.23 mmol/L (95% CI 0.03 mmol/L to 0.42 mmol/L) and 0.48 mmol/L (95% CI 0.15 mmol/L to 0.80 mmol/L), respectively.

CONCLUSION

Children treated with risperidone or quetiapine are at a significant risk for developing obesity, elevated waist circumference, and dyslipidemia during 12 months of treatment. These data emphasize the importance of regular monitoring for early identification and treatment of metabolic side effects.

Rationale and Considerations for the Internet-Based Delivery of Parent-Child Interaction Therapy

Given the enormous individual, familial, and societal costs associated with early disruptive behavior disorders, transformative efforts are needed to develop innovative options for overcoming traditional barriers to effective care and for broadening the availability of supported interventions. This paper presents the rationale and key considerations for a promising innovation in the treatment of early-onset disruptive behavior disorders-that is, the development of an Internet-based format for the delivery of Parent-Child Interaction Therapy (PCIT) directly to families in their own homes. Specifically, we consider traditional barriers to effective care, and discuss how technological innovations can overcome problems of treatment availability, accessibility, and acceptability. We then detail our current Internet-delivered PCIT treatment program (I-PCIT), which is currently being evaluated across multiple randomized clinical trials relative to waitlist comparison, and to traditional in-office PCIT. Embedded video clips of children treated with I-PCIT are used to illustrate novel aspects of the treatment.

Trends in Atypical Antipsychotics Prescribed to Children Six Years of Age or Less on Medicaid in Kentucky

OBJECTIVE

Studies have shown an increase in the use of antipsychotics to preschoolers for disruptive behavior and aggression. This study investigated the use of atypical antipsychotics in children ≤6 years of age in Kentucky who were on Medicaid.

METHODS

Kentucky Medicaid prescription claims data between 2001 and 2010 were examined for all children ≤6 years of age who had received an atypical antipsychotic. Drug type, diagnosis codes, and geographic trends were analyzed using descriptive statistics.

RESULTS

A total of 70,777 prescriptions were written to 6915 distinct children ≤6 years of age. The use of atypical antipsychotics in this age group increased over the years 2001-2010 with a peak ∼ 1.0% in 2004, and averaged 0.75% in 2010. Older male children were more likely to receive atypical antipsychotics, and risperidone accounted for two thirds of the prescriptions written. Mood disorders, primarily bipolar disorder, accounted for almost 75% of the diagnoses provided. Only 32% of the prescriptions were written by child psychiatrists. Geographic analysis showed significantly higher use in the Western part of the state (more than three times the state mean in some counties).

CONCLUSIONS

The use of atypical antipsychotics in children ≤6 years of age has declined from its peak, but remains substantial. The prescription rates for atypical antipsychotics by providers other than child psychiatrists, and the marked geographic variation in use across the state of Kentucky suggest that improved systems of mental healthcare for this population are needed.

Evidence-based psychological treatments for mental disorders: modifiable barriers to access and possible solutions

The prevalence of mental disorders is high and appears to be growing, yet the majority of individuals who meet diagnostic criteria for a mental disorder are not able to access an adequate treatment. While evidence-based psychological treatments (EBPTs) are effective single or adjunctive treatments for mental disorders, there is also evidence that access to these treatments is diminishing. We seek to highlight modifiable barriers to these problems at the patient, therapist, treatment, organization and government-levels of analysis. A range of solutions to each set of contributors is offered and domains for future research are highlighted. In particular, we focus on the need to continue to work toward innovation in treatment development while also solving the difficulties relating to the dissemination of EBPTs. Several relatively new concepts in the field will be discussed (implementation cliff, program drift, voltage drop and deployment treatment development) and we contrast America and England as examples of government-level processes that are in the process of major change with respect to EBPTs. We conclude that there is a need for people in our field to become more knowledgeable about, and get involved in, shaping public policy.

Psychotropic drug use among preschool children in the Medicaid program from 36 states

OBJECTIVES

We determined the prevalence of and indications for psychotropic medication among preschool children in Medicaid.

METHODS

We obtained 2000 to 2003 Medicaid Analytic Extract data from 36 states. We followed children in 2 cohorts, born in 1999 and 2000, up to age 4 years. We used logistic regression to model odds of receiving medications for (1) attention-deficit disorder/attention-deficit hyperactivity disorder, (2) depression or anxiety, and (3) psychotic illness or bipolar.

RESULTS

Overall, 1.19% of children received at least 1 psychotropic drug. Medications for attention-deficit disorder/attention-deficit hyperactivity disorder treatment were most common (0.61% of all children), followed by depression or anxiety (0.59%) and psychotic illness or bipolar (0.24%). Among children, boys, those of other or unknown race compared with White, and those with other insurance compared with fee for service-only had higher odds of receiving a prescription (odds ratio [OR]=1.80 [95% confidence interval (CI)=1.74, 1.86], 1.75 [corrected] [1.66, 1.85], and 1.14 [1.01, 1.28], respectively), whereas Black and Hispanic children had lower odds (OR=0.51 [95% CI=0.48, 0.53] and 0.37 [0.34, 0.39], respectively).

CONCLUSIONS

Preschoolers are receiving psychotropic medications despite limited evidence supporting safety or efficacy. Future research should focus on implementing medication use practice parameters in infant and toddler clinics, and expanding psychosocial interventions for young children with behavioral problems.

Some side effects and effcts on physical activity of second-generation antipsychotics: A study in children and adolescents

Background:

This study was designed to investigate the metabolic adverse effects (AEs) of second-generation antipsychotics (SGAs) and their relationship with physical activity and non-metabolic AE in children and adolescents.

Materials and Methods:

After exclusion of patients with metabolic syndrome, 62 patients (34 children, 28 adolescents) of both genders who were candidates for SGA therapy were selected. Metabolic parameters included fasting blood glucose (FBG), triglyceride (TG), blood pressure (BP), and waist circumference (WC); non-metabolic AEs and physical activity were evaluated at baseline, 1 month, and 3 months after starting the treatment.

Results:

Mean of post-treatment FBG and TG were significantly higher than the baseline values (P < 0.0001). Compared to the baseline value, significantly more patients developed abnormally high (AbH) FBG at the end point (P = 0.02). There was no significant difference in the frequency of patients with AbH-FBG either at the baseline or at the end point (P > 0.05). The frequency of patients with AbH-TG at the end point was not significantly higher than those with baseline AbH-TG (P = 0.10). Although no patient was obese at baseline, 11 (18%) patients developed abdominal obesity at the end point (P < 0.0001). There was no significant difference in the frequency of non-metabolic AE (P > 0.05). There was no significant correlation between metabolic and non-metabolic AE (P > 0.05). Frequency of inactive patients was significantly more than the baseline value (P-0.008), and abdominal obesity was significantly more prevalent in less active participants (P = 0.03).

Conclusion:

The present study showed the AE of SGA on FBG and TG, but no effect on BP and WC. We also found that children are more prone to develop abnormally high FBG.

Antipsychotic treatment for children and adolescents with schizophrenia spectrum disorders: protocol for a network meta-analysis of randomised trials

INTRODUCTION

Antipsychotic treatment in early-onset schizophrenia (EOS) lacks a rich evidence base, and efforts to rank different drugs concerning their efficacy have not proven any particular drug superior. In contrast to the literature regarding adult-onset schizophrenia (AOS), comparative effectiveness studies in children and adolescents are limited in number and size, and only a few meta-analyses based on conventional methodologies have been conducted.

METHODS AND ANALYSES

We will conduct a network meta-analysis of all randomised controlled trials (RCTs) that evaluate antipsychotic therapies for EOS to determine which compounds are efficacious, and to determine the relative efficacy and safety of these treatments when compared in a network meta-analysis. Unlike a contrast-based (standard) meta-analysis approach, an arm-based network meta-analysis enables statistical inference from combining both direct and indirect comparisons within an empirical Bayes framework. We will acquire eligible studies through a systematic search of MEDLINE, the Cochrane Central Registry of Controlled Trials, Clinicaltrials.gov and Centre for Reviews and Dissemination databases. Eligible studies should randomly allocate children and adolescents presenting with schizophrenia or a related non-affective psychotic condition to an intervention group or to a control group. Two reviewers will-independently and in duplicate-screen titles and abstracts, complete full text reviews to determine eligibility, and subsequently perform data abstraction and assess risk of bias of eligible trials. We will conduct meta-analyses to establish the effect of all reported therapies on patient-relevant efficacy and safety outcomes when possible.

ETHICS AND DISSEMINATION

No formal ethical procedures regarding informed consent are required as no primary data collection is undertaken. The review will help facilitate evidence-based management, identify key areas for future research, and provide a framework for conducting large systematic reviews combining direct and indirect comparisons. The study will be disseminated by peer-reviewed publication and conference presentation.

The effects of prior authorization policies on medicaid-enrolled children's use of antipsychotic medications: evidence from two mid-Atlantic states

OBJECTIVE

The purpose of this study was to examine the impact of prior authorization policies on the receipt of antipsychotic medication for Medicaid-enrolled children.

METHODS

Using de-identified administrative Medicaid data from two large, neighboring, mid-Atlantic states from November 2007 through June 2011, we identified subjects <18 years of age using antipsychotics, from the broader group of children and adolescents receiving behavioral health services or any psychotropic medication. Prior authorization for antipsychotics was required for children in State A <6 years of age from September 2008, and for children <13 years of age from August 2009. No such prior authorizations existed in State B during that period. Filled prescriptions were identified in the data using national drug codes. Using a triple-difference strategy (using differences among the states, time periods, and differences in antidepressant prescribing rates among states over the same time periods), we examined the effect of the prior authorization policy on the rate at which antipsychotic prescriptions were filled for Medicaid-enrolled children and adolescents.

RESULTS

The impact of prior authorization policies on antipsychotic medication use varied by age: Among 6-12 year old children, the impact of the prior authorization policy on antipsychotic medication prescribing was a modest but statistically significant decrease of 0.47% after adjusting for other factors; there was no effect of the prior authorization among children 0-5 years.

CONCLUSIONS

Prior authorization policies had a modest but statistically significant effect on antipsychotic use in 6-12 year old children, but had no impact in younger children. Future research is needed to understand the utilization and clinical effects of prior authorization and other policies and interventions designed to influence antipsychotic use in children.

Antipsychotic polypharmacy in children and adolescents at discharge from psychiatric hospitalization

STUDY OBJECTIVE

Antipsychotic polypharmacy-the use of more than one antipsychotic concomitantly-has increased in children and adolescents and may be associated with increased adverse effects, nonadherence, and greater costs. Thus, we sought to examine the demographic and clinical characteristics of psychiatrically hospitalized children and adolescents who were prescribed antipsychotic polypharmacy and to identify predictors of this prescribing pattern.

DESIGN

Retrospective medical record review.

SETTING

The inpatient psychiatric unit of a large, acute care, urban children's hospital.

PATIENTS

One thousand four hundred twenty-seven children and adolescents who were consecutively admitted and discharged between September 2010 and May 2011.

MEASUREMENTS AND MAIN RESULTS

At discharge, 840 (58.9%) of the 1427 patients were prescribed one or more antipsychotics, and 99.3% of these received second-generation antipsychotics. Of these 840 patients, 724 (86.2%) were treated with antipsychotic monotherapy, and 116 (13.8%) were treated with antipsychotic polypharmacy. Positive correlations with antipsychotic polypharmacy were observed for placement or custody outside the biological family; a greater number of previous psychiatric admissions; longer hospitalizations; admission for violence/aggression or psychosis; and intellectual disability, psychotic, disruptive behavior, or developmental disorder diagnoses. Negative correlations with antipsychotic polypharmacy included admission for suicidal ideation/attempt or depression, and mood disorder diagnoses. Significant predictors of antipsychotic polypharmacy included admission for violence or aggression (odds ratio [OR] 2.76 [95% confidence interval (CI) 1.36-5.61]), greater number of previous admissions (OR 1.21 [95% CI 1.10-1.33]), and longer hospitalizations (OR 1.08 [95% CI 1.04-1.12]). In addition, diagnoses of intellectual disability (OR 2.62 [95% CI 1.52-4.52]), psychotic disorders (OR 5.60 [95% CI 2.29-13.68]), and developmental disorders (OR 3.18 [95% CI 1.78-5.65]) were predictors of antipsychotic polypharmacy.

CONCLUSION

Certain youth may have a higher likelihood of being prescribed antipsychotic polypharmacy, which should prompt careful consideration of medication treatment options during inpatient hospitalization. Future examinations of the rationale for combining antipsychotics, along with the long-term safety, tolerability, and cost effectiveness of these therapies, in youth are urgently needed.

Adult response to olanzapine or clozapine treatment is altered by adolescent antipsychotic exposure: a preclinical test in the phencyclidine hyperlocomotion model

This study examined how repeated olanzapine (OLZ) or clozapine (CLZ) treatment in adolescence alters sensitivity to the same drug in adulthood in the phencyclidine (PCP) hyperlocomotion model. Male adolescent Sprague-Dawley rats (postnatal day (P) 44-48) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10.0 or 20.0 mg/kg, sc) and tested in the PCP (3.2 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. Then a challenge test with OLZ (0.5 mg/kg) or CLZ (5.0 mg/kg) was administered either during adolescence (~P 51) or after the rats matured into adults (~P 76 and 91). During adolescence, repeated OLZ or CLZ treatment produced a persistent inhibition of PCP-induced hyperlocomotion across the five test days. In the challenge test during adolescence, rats previously treated with OLZ did not show a significantly stronger inhibition of PCP-induced hyperlocomotion than those previously treated with vehicle (VEH). In contrast, those previously treated with CLZ showed a weaker inhibition than the VEH controls. When assessed in adulthood, the enhanced sensitivity to OLZ and the decreased sensitivity to CLZ were detected on ~P 76, even on ~P 91 in the case of OLZ. These findings suggest that adolescent OLZ or CLZ exposure can induce long-term alterations in antipsychotic response that persist into adulthood.

Cardiometabolic outcomes in children and adolescents following discontinuation of long-term risperidone treatment

OBJECTIVE

Second-generation antipsychotics (SGAs) cause weight gain and cardiometabolic abnormalities in children and adolescents. Less well-investigated is the outcome of these adverse events following SGA discontinuation, which we examined.

METHODS

Medically healthy 7 to 17-year-old patients treated with risperidone for ≥6 months were enrolled and returned for follow-up, 1.5 years later. Treatment history was extracted from the medical and pharmacy records. Anthropometric and laboratory measurements were obtained at each research visit. Multivariable linear regression analysis and Fisher's exact test were used to compare participants who remained on risperidone at follow-up (Risp Cont Group) with those who had discontinued SGA treatment (SGA Disc Group) and those who had switched to another SGA (SGA Cont Group). Correlational analyses examined the association between change in age-sex specific body mass index (BMI) z score between study entry and follow-up and change in cardiometabolic outcomes.

RESULTS

The sample consisted of 101 participants (93% male) with a mean age of 11.7±2.6 years at study entry. The majority had an externalizing disorder and received 0.03±0.02 mg/kg/day of risperidone, for 2.5±1.6 years. At follow-up, 18% (n=18) were in the SGA Disc Group and 9% (n=9) were in the SGA Cont Group. BMI z score decreased in the SGA Disc Group, remained unchanged in the Risp Cont Group (n=74), and increased in the SGA Cont Group. Importantly, the change in BMI z score between study entry and follow-up was significantly correlated with the change in systolic and diastolic blood pressure z scores, heart rate, waist circumference, percent body fat, inflammatory markers, fasting total insulin, homeostatic model assessment insulin resistance index (HOMA-IR), C-peptide, total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol, triglycerides, triglycerides/HDL ratio, and leptin.

CONCLUSIONS

Following several years of treatment, risperidone discontinuation is associated with a reversal of the excessive weight gain, mediated by a negative energy balance, and a corresponding improvement in cardiometabolic parameters.

The occasional case against broad dissemination and implementation: retaining a role for specialty care in the delivery of psychological treatments

Mental illness imposes a staggering public health burden in the United States. Although the past 40 years have witnessed tremendous advances in the identification of evidence-based practices (EBPs) in psychological treatments, gaps persist between treatment in experimental settings and services available in the community. In response, considerable attention and large financial commitments have focused in recent years on broad dissemination and implementation efforts designed to improve the quality of psychological services delivered by a variety of generalist practitioners across practice settings. Increasingly, under the influence of the Patient Protection and Affordable Care Act, it is envisioned that these generalists will practice in integrated primary care settings. These advances hold enormous potential, and yet, given the tremendous diversity of mental health problems and human suffering, broad dissemination and implementation efforts to generalists alone may not be sufficient to adequately address the burden of mental illness. Some EBPs may prove too complex for universal dissemination, and the time and expense required for quality dissemination and implementation preclude large-scale training in the treatment of low base rate disorders. As dissemination and implementation efforts work to ensure a quality generalist mental health care workforce, herein we highlight the vital need for available specialty care in the delivery of psychological treatments. Given traditional barriers that interfere with the accessibility of specialty care, we propose the transformative potential of a specialty behavioral telehealth care workforce, transacting with the generalist practitioner workforce to collectively ensure the highest quality and timely delivery of needed treatments to affected individuals.

Trends in the parent-report of health care provider-diagnosed and medicated attention-deficit/hyperactivity disorder: United States, 2003-2011

OBJECTIVE

Data from the 2003 and 2007 National Survey of Children's Health (NSCH) reflect the increasing prevalence of parent-reported attention-deficit/hyperactivity disorder (ADHD) diagnosis and treatment by health care providers. This report updates these prevalence estimates for 2011 and describes temporal trends.

METHOD

Weighted analyses were conducted with 2011 NSCH data to estimate prevalence of parent-reported ADHD diagnosis, current ADHD, current medication treatment, ADHD severity, and mean age of diagnosis for U.S. children/adolescents aged 4 to 17 years and among demographic subgroups. A history of ADHD diagnosis (2003-2011), as well as current ADHD and medication treatment prevalence (2007-2011), were compared using prevalence ratios and 95% confidence intervals.

RESULTS

In 2011, 11% of children/adolescents aged 4 to 17 years had ever received an ADHD diagnosis (6.4 million children). Among those with a history of ADHD diagnosis, 83% were reported as currently having ADHD (8.8%); 69% of children with current ADHD were taking medication for ADHD (6.1%, 3.5 million children). A parent-reported history of ADHD increased by 42% from 2003 to 2011. Prevalence of a history of ADHD, current ADHD, medicated ADHD, and moderate/severe ADHD increased significantly from 2007 estimates. Prevalence of medicated ADHD increased by 28% from 2007 to 2011.

CONCLUSIONS

Approximately 2 million more U.S. children/adolescents aged 4 to 17 years had been diagnosed with ADHD in 2011, compared to 2003. More than two-thirds of those with current ADHD were taking medication for treatment in 2011. This suggests an increasing burden of ADHD on the U.S. health care system. Efforts to further understand ADHD diagnostic and treatment patterns are warranted.

Internet-delivered, family-based treatment for early-onset OCD: a preliminary case series

Given the burdens of early-onset obsessive-compulsive disorder (OCD), limitations in the broad availability and accessibility of evidence-based care for affected youth present serious public health concerns. The growing potential for technological innovations to transform care for the most traditionally remote and underserved families holds enormous promise. This article presents the rationale, key considerations, and a preliminary case series for a promising behavioral telehealth innovation in the evidence-based treatment of early-onset OCD. We developed an Internet-based format for the delivery of family-based treatment for early-onset OCD directly to families in their homes, regardless of their geographic proximity to a mental health facility. Videoteleconferencing (VTC) methods were used to deliver real-time cognitive-behavioral therapy centering on exposure and response prevention to affected families. Participants in the preliminary case series included 5 children between the ages of 4 and 8 (M Age = 6.5) who received the Internet-delivered treatment format. All youth completed a full treatment course, all showed OCD symptom improvements and global severity improvements from pre- to posttreatment, all showed at least partial diagnostic response, and 60% no longer met diagnostic criteria for OCD at posttreatment. No participants got worse, and all mothers characterized the quality of services received as "excellent." The present work adds to a growing literature supporting the potential of VTC and related computer technology for meaningfully expanding the reach of supported treatments for OCD and lays the foundation for subsequent controlled evaluations to evaluate matters of efficacy and engagement relative to standard in-office evidence-based care.

Preschool anxiety disorders in pediatric primary care: prevalence and comorbidity

OBJECTIVE

We sought to establish prevalence rates and detail patterns of comorbidity for generalized anxiety disorder, separation anxiety disorder, and social phobia in preschool-aged children.

METHOD

The Duke Preschool Anxiety Study, a screen-stratified, cross-sectional study, drew from pediatric primary care and oversampled for children at risk for anxiety. A total of 917 parents of preschool children (aged 2-5 years) completed the Preschool Age Psychiatric Assessment.

RESULTS

Generalized anxiety disorder, separation anxiety disorder, and social phobia are common in preschool-aged children attending pediatric primary care. Three-fourths of preschoolers with an anxiety disorder only had a single anxiety disorder. Generalized anxiety disorder displayed the greatest degree of comorbidity: with separation anxiety disorder (odds ratio [OR] = 4.1, 95% CI = 2.0-8.5), social phobia (OR = 6.4, 95% CI = 3.1-13.4), disruptive behavior disorders (OR = 5.1, 95% CI = 1.6-15.8), and depression (OR = 3.7, 95% CI = 1.1-12.4).

CONCLUSIONS

The weakness of association between generalized anxiety disorder and depression stands in contrast to substantial associations between these 2 disorders reported in older individuals. Attenuated associations in preschool-aged children could translate into clinical opportunities for targeted early interventions, aimed at modifying the developmental trajectory of anxiety disorders.

Use of antipsychotic medications in pediatric populations: what do the data say?

Recent reports of antipsychotic medication use in pediatric populations describe large increases in rates of use. Much interest in the increasing use has focused on potentially inappropriate prescribing for non-Food and Drug Administration-approved uses and use amongst youth with no mental health diagnosis. Different studies of antipsychotic use have used different time periods, geographic and insurance populations of youth, and aggregations of diagnoses. We review recent estimates of use and comment on the similarities and dissimilarities in rates of use. We also report new data obtained on 11 health maintenance organizations that are members of the Mental Health Research Network in order to update and extend the knowledge base on use by diagnostic indication. Results indicate that most use in pediatric populations is for disruptive behaviors and not psychotic disorders. Differences in estimates are likely a function of differences in methodology; however, there is remarkable consistency in estimates of use by diagnosis.

Psychotropic medication use and polypharmacy in children with autism spectrum disorders

OBJECTIVE

The objectives of this study were to examine rates and predictors of psychotropic use and multiclass polypharmacy among commercially insured children with autism spectrum disorders (ASD).

METHODS

This retrospective observational study used administrative medical and pharmacy claims data linked with health plan enrollment and sociodemographic information from 2001 to 2009. Children with ASD were identified by using a validated ASD case algorithm. Psychotropic polypharmacy was defined as concurrent medication fills across ≥ 2 classes for at least 30 days. Multinomial logistic regression was used to model 5 categories of psychotropic use and multiclass polypharmacy.

RESULTS

Among 33,565 children with ASD, 64% had a filled prescription for at least 1 psychotropic medication, 35% had evidence of psychotropic polypharmacy (≥ 2 classes), and 15% used medications from ≥ 3 classes concurrently. Among children with polypharmacy, the median length of polypharmacy was 346 days. Older children, those who had a psychiatrist visit, and those with evidence of co-occurring conditions (seizures, attention-deficit disorders, anxiety, bipolar disorder, or depression) had higher odds of psychotropic use and/or polypharmacy.

CONCLUSIONS

Despite minimal evidence of the effectiveness or appropriateness of multidrug treatment of ASD, psychotropic medications are commonly used, singly and in combination, for ASD and its co-occurring conditions. Our results indicate the need to develop standards of care around the prescription of psychotropic medications to children with ASD.

National trends in psychotropic medication use in young children: 1994-2009

OBJECTIVE

To examine recent national trends in psychotropic use for very young children at US outpatient medical visits.

METHODS

Data for 2- to 5-year-old children (N = 43 598) from the 1994-2009 National Ambulatory and National Hospital Ambulatory Medical Care Surveys were used to estimate the weighted percentage of visits with psychotropic prescriptions. Multivariable logistic regression was used to identify factors associated with psychotropic use. Time effects were examined in 4-year blocks (1994-1997, 1998-2001, 2002-2005, and 2006-2009).

RESULTS

Psychotropic prescription rates were 0.98% from 1994-1997, 0.83% from 1998-2001, 1.45% from 2002-2005, and 1.00% from 2006-2009. The likelihood of preschool psychotropic use was highest in 2002-2005 (1994-1997 adjusted odds ratio [AOR] versus 2002-2005: 0.67; 1998-2001 AOR versus 2002-2005: 0.63; 2006-2009 AOR versus 2002-2005: 0.64), then diminished such that the 2006-2009 probability of use did not differ from 1994-1997 or from 1998-2001. Boys (AOR versus girls: 1.64), white children (AOR versus other race: 1.42), older children (AOR for 4 to 5 vs 2 to 3 year olds: 3.87), and those lacking private insurance (AOR versus privately insured: 2.38) were more likely than children from other groups to receive psychotropic prescriptions.

CONCLUSIONS

Psychotropic prescription was notable for peak usage in 2002-2005 and sociodemographic disparities in use. Further study is needed to discern why psychotropic use in very young children stabilized in 2006-2009, as well as reasons for increased use in boys, white children, and those lacking private health insurance.

Prescription of psychiatric medications and polypharmacy in the LAMS cohort

OBJECTIVE

This study evaluated demographic and clinical correlates and predictors of polypharmacy at baseline assessment in the Longitudinal Assessment of Manic Symptoms (LAMS) sample, a cohort of children age six to 12 years at their first outpatient mental health visit at university-affiliated clinics.

METHODS

Use of medications in four classes (mood stabilizers, antidepressants, antipsychotics, and stimulants) was assessed, and the Service Assessment for Children and Adolescents classified lifetime and current use of various services. Analyses examined correlates of the number of medications prescribed and odds of polypharmacy, defined as use of two or more concurrent medications.

RESULTS

In the total sample, 201 of 698 participants (29%) were prescribed two or more medications. These participants had lower Children's Global Assessment Scale scores, more comorbid disorders, and higher baseline parent-reported mood symptoms than those prescribed no or one medication. White youths were three times as likely as nonwhite youths to be receiving two or more psychotropics, even after adjustment for other demographic and clinical characteristics. Of 262 participants (38% of sample) not being treated with medications, 252 (96%) had a diagnosis of at least one psychiatric disorder (74% had two or more).

CONCLUSIONS

Findings suggest that patients with greater severity and comorbidity were more likely to receive two or more medications. However, 38% of these children with serious disorders were not receiving psychotropic medication at the time of this assessment. Results counter findings suggesting overtreatment with medications of children with psychiatric disorders in the community.

Possible mechanisms for the skeletal effects of antipsychotics in children and adolescents

The increasing use of antipsychotics (APs) to treat pediatric psychiatric conditions has led to concerns over the long-term tolerability of these drugs. While the risk of cardiometabolic abnormalities has received most of the attention, preclinical and clinical studies provide preliminary evidence that APs can adversely impact bone metabolism. This would be most concerning in children and adolescents as suboptimal bone accrual during development may lead to increased fracture risk later in life. However, the potential mechanisms of action through which APs may impact bone turnover and, consequently, bone mineral content are not clear. Emerging data suggest that the skeletal effects of APs are complex, with APs directly and indirectly impacting bone cells through modulation of multiple signaling pathways, including those involving dopamine D2, serotonin, adrenergic, and prolactin receptors, as well as by affecting gonadotropins. Determining the action of APs on skeletal development is further complicated by polypharmacy. In children and adolescents, APs are frequently coprescribed with psychostimulants and selective serotonin reuptake inhibitors, which have also been linked to changes in bone metabolism. This review discusses the mechanisms by which APs may influence bone metabolism. Also covered are preclinical and pediatric findings concerning the impact of APs on bone turnover. However, the dearth of clinical information despite the potential public health significance of this issue underscores the need for further studies. The review ends with a call for clinicians to be vigilant about promoting optimal overall health in chronically ill youth with psychopathology, particularly when pharmacotherapy is unavoidable.

Pharmacoepidemiology of antipsychotic use in youth with ADHD: trends and clinical implications

Although concern has been raised about antipsychotic prescribing to youth with attention-deficit/hyperactivity disorder (ADHD), the available database is limited to individual studies. Therefore, in order to provide a synthesis of prevalence and time trends, we conducted a systematic review and pooled analysis of pharmaco-epidemiologic data on antipsychotic use in ADHD youth. Of 1806 hits, 21 studies (N) were retained that reported analyzable data for three separate populations: 1) antipsychotic-treated youth (N = 15, n = 341,586); 2) ADHD youth (N = 9, n = 6,192,368), and 3) general population youth (N = 5, n = 14,284,916). Altogether, 30.5 ± 18.5% of antipsychotic-treated youth had ADHD. In longitudinal studies, this percentage increased over time (1998-2007) from 21.7 ± 7.1% to 27.7 ± 7.7%, ratio = 1.3 ± 0.4. Furthermore, 11.5 ± 17.5% of ADHD youth received antipsychotics. In longitudinal studies, this percentage also increased (1998-2006) from 5.5 ± 2.6% to 11.4 ± 6.7%, ratio = 2.1 ± 0.6. Finally, 0.12 ± 0.07% of youth in the general population were diagnosed with ADHD and received antipsychotics. Again, in longitudinal studies, this percentage increased over time (1993-2007): 0.13 ± 0.09% to 0.44 ± 0.49%, ratio = 3.1 ± 2.2. Taken together, these data indicate that antipsychotics are used by a clinically relevant and increasing number of youth with ADHD. Reasons for and risk/benefit ratios of this practice with little evidence base require further investigation.

A novel group therapy for children with ADHD and severe mood dysregulation

OBJECTIVE

No psychosocial treatments have been developed for children with ADHD and severe mood dysregulation (SMD) despite the significant prevalence and morbidity of this combination. Therefore, the authors developed a novel treatment program for children with ADHD and SMD.

METHOD

The novel therapy program integrates components of cognitive-behavioral therapies for affect regulation with a parent-training intervention for managing recurrent defiant behaviors. It consists of nine 105-min child and parent groups run in unison. A pilot trial was conducted with seven participants with ADHD and SMD ages 7 to 12 who were on a stable stimulant regimen.

RESULTS

Six of the seven (86%) families completed the program. Participants showed large improvements in depressive symptoms, mood lability, and global functioning. Milder improvements in externalizing behaviors were observed.

CONCLUSION

Results suggest the feasibility and potential efficacy of the therapy program for children with ADHD and SMD and warrant a larger controlled trial.
