Infective endocarditis in childhood.

G F Sholler, R E Hawker, J M Celermajer

    Pediatric Cardiology

    Summary
    This summary is machine-generated.

    Infective endocarditis in children, often linked to structural heart disease, is primarily caused by streptococci and staphylococci. Outcomes vary by organism, with Staphylococcus aureus infections having a higher mortality rate.

    Area of Science:

    • Pediatric Cardiology
    • Infectious Diseases
    • Critical Care Medicine

    Background:

    • Infective endocarditis (IE) is a serious infection affecting heart valves, particularly in children with underlying structural heart disease.
    • Understanding the epidemiology and outcomes of pediatric IE is crucial for timely diagnosis and management.

    Purpose of the Study:

    • To describe the clinical characteristics, causative organisms, and outcomes of infective endocarditis in children.
    • To identify risk factors and prognostic indicators for pediatric IE.

    Main Methods:

    • Retrospective review of 37 pediatric cases of infective endocarditis diagnosed between 1971 and 1983.
    • Analysis of patient demographics, pre-existing conditions, identified pathogens, treatment, and clinical outcomes.

    Main Results:

    • Structural heart disease was present in 95% of cases; 15 children had cyanotic congenital heart disease, 11 with prior shunts.
    • Streptococci (43%) and staphylococci (27%) were the most common pathogens identified via blood culture.
    • The overall mortality rate was 13.5%, with higher mortality in Staphylococcus aureus infections (40%) compared to Streptococcus viridans (0%).
    • Survivors experienced significant complications, including valve replacement (4) and central nervous system issues (3).

    Conclusions:

    • Pediatric infective endocarditis predominantly affects children with pre-existing heart conditions.
    • Prompt diagnosis and appropriate antimicrobial therapy are essential, considering the specific causative organisms and their sensitivities.
    • The study highlights the need for vigilance in managing IE, particularly in high-risk pediatric populations.
