Insights
Long-term antipsychotic use in young people increases metabolic risks but not cardiovascular risks. This study analyzed data from over 48,000 individuals across four countries, highlighting the importance of monitoring metabolic health during extended antipsychotic treatment.
Area of Science:
- Pharmacovigilance
- Pediatric Pharmacology
- Cardiovascular Epidemiology
Background:
- Antipsychotic medications are widely used in children and young adults.
- Limited real-world data exists on the comparative risks of cardiovascular and metabolic events associated with antipsychotic use in this population across different countries.
- Understanding these risks is crucial for optimizing treatment strategies and patient safety.
Purpose of the Study:
- To evaluate the risks of cardiovascular and metabolic events in children and young adults receiving antipsychotic treatment.
- To compare these risks across different exposure durations and geographical regions.
Main Methods:
- A multinational self-controlled case series (SCCS) study was conducted using nationwide databases from Taiwan, Korea, Hong Kong, and the UK.
- The study included approximately 100 million individuals, focusing on patients aged 6-30 years exposed to antipsychotics.
- Cardiovascular events (stroke, ischemic heart disease, myocardial infarction) and metabolic events (hypertension, type 2 diabetes, dyslipidemia) were analyzed across various antipsychotic exposure windows.
Main Results:
- The analysis included 48,515 individuals.
- A statistically significant increased risk of metabolic events was observed only with long-term exposure (more than 90 days), with a pooled incidence rate ratio (IRR) of 1.29 (95% CI 1.20-1.38).
- No significant association was found between antipsychotic exposure and cardiovascular events across any exposure window.
Conclusions:
- Long-term exposure to antipsychotics is associated with an increased risk of metabolic events in children and young adults.
- Antipsychotic use in this age group did not appear to trigger cardiovascular events.
- These findings underscore the need for vigilant metabolic monitoring in pediatric and young adult patients on extended antipsychotic therapy.
Aims:
The risk of antipsychotic-associated cardiovascular and metabolic events may differ among countries, and limited real-world evidence has been available comparing the corresponding risks among children and young adults. We, therefore, evaluated the risks of cardiovascular and metabolic events in children and young adults receiving antipsychotics.
Methods:
We conducted a multinational self-controlled case series (SCCS) study and included patients aged 6-30 years old who had both exposure to antipsychotics and study outcomes from four nationwide databases of Taiwan (2004-2012), Korea (2010-2016), Hong Kong (2001-2014) and the UK (1997-2016) that covers a total of approximately 100 million individuals. We investigated three antipsychotics exposure windows (i.e., 90 days pre-exposure, 1-30 days, 30-90 days and 90 + days of exposure). The outcomes were cardiovascular events (stroke, ischaemic heart disease and acute myocardial infarction), or metabolic events (hypertension, type 2 diabetes mellitus and dyslipidaemia).
Results:
We included a total of 48 515 individuals in the SCCS analysis. We found an increased risk of metabolic events only in the risk window with more than 90-day exposure, with a pooled IRR of 1.29 (95% CI 1.20-1.38). The pooled IRR was 0.98 (0.90-1.06) for 1-30 days and 0.88 (0.76-1.02) for 31-90 days. We found no association in any exposure window for cardiovascular events. The pooled IRR was 1.86 (0.74-4.64) for 1-30 days, 1.35 (0.74-2.47) for 31-90 days and 1.29 (0.98-1.70) for 90 + days.
Conclusions:
Long-term exposure to antipsychotics was associated with an increased risk of metabolic events but did not trigger cardiovascular events in children and young adults.
