Comparative cardiometabolic risk of antipsychotics in children, adolescents and young adults

Cross-Regional Data Initiative for the Assessment and Development of Treatment for Neurological and Mental Disorders

Purpose

To describe and categorize detailed components of databases in the Neurological and Mental Health Global Epidemiology Network (NeuroGEN).

Methods

An online 132-item questionnaire was sent to key researchers and data custodians of NeuroGEN in North America, Europe, Asia and Oceania. From the responses, we assessed data characteristics including population coverage, data follow-up, clinical information, validity of diagnoses, medication use and data latency. We also evaluated the possibility of conversion into a common data model (CDM) to implement a federated network approach. Moreover, we used radar charts to visualize the data capacity assessments, based on different perspectives.

Results

The results indicated that the 15 databases covered approximately 320 million individuals, included in 7 nationwide claims databases from Australia, Finland, South Korea, Taiwan and the US, 6 population-based electronic health record databases from Hong Kong, Scotland, Taiwan, the Netherlands and the UK, and 2 biomedical databases from Taiwan and the UK.

Conclusion

The 15 databases showed good potential for a federated network approach using a common data model. Our study provided publicly accessible information on these databases for those seeking to employ real-world data to facilitate current assessment and future development of treatments for neurological and mental disorders.

Weight Gain During Antipsychotic Treatment in Children, Adolescents, and Adults: A Disproportionality Analysis in the Global Pharmacovigilance Database, Vigibase®

INTRODUCTION

While antipsychotic-induced weight gain has been widely described in adults, it has yet to be better characterized in children and adolescents.

OBJECTIVE

The aim of this study was to assess antipsychotic-induced weight-gain reporting in children and adolescents as compared to adults, and according to the type of antipsychotic.

METHODS

The study is an observational, case-non-case study using individual case safety reports from the WHO global pharmacovigilance database VigiBase^® from 1 January 2000 to 2 June 2021. Disproportionality in antipsychotic-related weight-gain reporting in children and adolescents compared to adults was evaluated based on reporting odds ratios (RORs) with corresponding 95% confidence intervals (CIs) through multivariate logistic regression modeling. Analysis was adjusted for sex, region of reporting, year of notification, reporter qualification, concomitant use of antidepressants, and use of more than one antipsychotic.

RESULTS

Among 282,224 antipsychotic-related spontaneous reports included in this analysis, we identified 16,881 (6.0%) weight-gain cases. Disproportionality in weight-gain reporting was found in children (adjusted ROR (aROR) 3.6; 95% CI 3.3-3.8) and in adolescents (aROR 2.3; 95% CI 2.2-2.4) compared to adults. Use of risperidone was associated with the highest increase in weight-gain reporting in children (aROR 4.9; 95% CI 3.9-6.1) and adolescents (aROR 3.6; 95% CI 3.1-4.1).

CONCLUSIONS

Compared to adults, weight-gain reporting with antipsychotics was disproportionally higher in the pediatric population, especially in children under 12 years of age. Considering the impact of weight gain on global morbidity and mortality, physicians should closely monitor weight gain in young patients, especially children on risperidone.

When to Use Amisulpride in Adolescents: A Retrospective Chart Examination of Inpatients

PURPOSE/BACKGROUND

Despite increasing interest in amisulpride, current knowledge about its use in the pediatric population is scarce. This chart review aimed to investigate the use of amisulpride in a naturalistic adolescent population.

METHODS/PROCEDURES

Electronic medical records of a tertiary care adolescent inpatient unit were screened between January 2015 and April 2021. Sociodemographic data and all clinical information were collected via data collection forms, and targeted symptoms were obtained from patients' files. Patients with early-onset psychotic disorders (n = 58), bipolar I disorder (n = 29), major depressive disorder (n = 14), and other psychiatric diagnoses (n = 9) were included. Treatment response was defined as a Clinical Global Impression-Improvement of at least much improvement after treatment.

FINDINGS/RESULTS

Median titration rate of amisulpride was 400 mg/wk, and the maximum administered daily dose ranged between 100 and 1200 mg/d. The maximum daily dose and number of previous antipsychotics were higher in the early-onset psychotic disorder group. Persistent positive symptoms and resistance to previous treatments were leading causes for amisulpride treatment. Other indications were also impulsive/disruptive behaviors, antipsychotic adverse effects, depressive symptoms, somatic complaints, and abnormalities in liver function tests. Finally, patients with lower daily treatment doses and more previous antipsychotic trials are less likely to benefit from the treatment.

IMPLICATIONS/CONCLUSIONS

Persistent psychotic/mood symptoms, impulsive/disruptive behaviors, and abnormalities in liver function tests were reasons for the amisulpride treatment in adolescents. Randomized placebo-controlled trials are needed to evaluate the efficacy and safety of the treatment in adolescents.

Monitoring of metabolic side-effects in children and adolescents prescribed antipsychotic medication: A systematic review

OBJECTIVES

Prescribing antipsychotic medications to children and adolescents with severe mental and developmental disorders is common; however, there is a lack of consensus on appropriate metabolic monitoring for this population. This review systematically evaluates studies examining metabolic monitoring of children and adolescents prescribed antipsychotic medication to understand the clinical practice of metabolic monitoring and identify opportunities to improve the safety of antipsychotic prescribing in this population.

METHODS

A systematic search for original research on metabolic monitoring in children and adolescents prescribed antipsychotics was conducted in six databases (PubMed, EMBASE, PsycINFO, The Cochrane Library [Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CENTRAL], Cochrane Methodology Register and Web of Science [Science and Social Science Citation Index]) from inception to February 2020 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were assessed for quality and findings summarised using narrative synthesis.

RESULTS

Fifteen papers were identified. Studies agreed on the need for metabolic monitoring; however, there was a gap between guideline-recommended practice and clinical practice. Variable rates of baseline and subsequent monitoring were reported for both physical and biochemical parameters, with particularly low rates for monitoring requiring venesection. Younger age was also associated with lower monitoring rates. Implementation of quality improvement activities (new guidelines, staff education and checklists) improved monitoring rates although the measurement of biochemical parameters still occurred in only a minority of children.

CONCLUSION

Despite widespread awareness and concern regarding metabolic side-effects, monitoring occurred inconsistently and infrequently, particularly for biochemical parameters requiring venesection. Monitoring of anthropometric measures (weight, body mass index and waist circumference) with escalation to more laboratory testing where metabolic concerns are identified may improve monitoring. Minimising iatrogenic harm, through reduced antipsychotic prescription where possible, is a clinical priority in this population.
