Association between CHD and cerebral abscess: insights from a national database

Area of Science:

• Pediatric Neurology
• Cardiology
• Infectious Diseases

Background:

• Congenital heart disease (CHD) has been historically linked to cerebral abscess development.
• Understanding this association is crucial for pediatric patient care.

Purpose of the Study:

• To investigate the association between congenital heart disease (CHD) and the occurrence of cerebral abscess in an inpatient pediatric population.
• To determine if CHD increases the risk of cerebral abscess in children.

Main Methods:

• Retrospective cohort study using the Pediatric Health Information System database (2016-2021).
• Analyzed data from 426,029 pediatric intensive care unit admissions.
• Compared cerebral abscess incidence in patients with and without CHD.

Main Results:

• A total of 1,387 (0.3%) patients developed cerebral abscesses.
• 88 (0.1%) of 80,927 patients with CHD experienced a cerebral abscess (OR 0.29).
• Seizures, cerebral edema, stroke, shock, surgery, and older age increased abscess risk; mortality was not associated.

Conclusions:

• Patients with CHD were less likely to develop cerebral abscesses compared to those without CHD.
• Cerebral abscess is a rare complication in the contemporary pediatric inpatient population.
• No significant association found between CHD and cerebral abscess development.
