Long-term outcomes after group B streptococcus infection: a cohort study

Area of Science:

• Pediatric Infectious Diseases
• Neonatal Health
• Epidemiology

Background:

• Group B Streptococcus (GBS) is a significant cause of neonatal infections.
• Understanding the long-term health sequelae of GBS infection is crucial for pediatric care.

Purpose of the Study:

• To determine the long-term risk of mortality and hospitalisation in children following infant GBS infection.
• To identify specific health outcomes associated with GBS infection in childhood.

Main Methods:

• A population-based cohort study was conducted in New South Wales, Australia.
• Live births between 2000 and 2011 were analyzed, comparing outcomes of children with and without GBS infection diagnoses.
• International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) codes were used for GBS identification.

Main Results:

• Infants with GBS infection had higher rates of prematurity, low birth weight, and lower Apgar scores.
• Children with GBS infection showed a threefold increased adjusted odds of death and rehospitalisation.
• GBS survivors experienced more frequent and longer hospitalisations, with increased risks of genitourinary and nervous system issues.

Conclusions:

• Despite declining GBS infection rates, the long-term health risks for affected children remain elevated, particularly in the first five years of life.
• Survivors of GBS infection are at higher risk for chronic conditions, including cerebral palsy and epilepsy, requiring ongoing medical management.
