Empyema in infancy and childhood

Area of Science:

• Pediatric Infectious Diseases
• Thoracic Surgery
• Clinical Microbiology

Background:

• Empyema, a serious thoracic infection, presents diagnostic and therapeutic challenges, particularly in pediatric populations.
• Understanding causative organisms and treatment efficacy is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the incidence, causative organisms, treatment responses, and prognostic factors of empyema in a pediatric cohort.
• To compare the effectiveness of different antibiotic regimens in managing pediatric empyema.

Main Methods:

• Retrospective analysis of 108 pediatric empyema cases over an 18-month period.
• Identification of causative pathogens, primarily Staphylococcus aureus.
• Evaluation of treatment outcomes based on antibiotic combinations (cloxacillin/gentamicin vs. penicillin/gentamicin) and need for interventions like intercostal drainage.

Main Results:

• Empyema incidence was 2.17%, with Staphylococcus aureus being the most frequent pathogen (17.6%).
• Cloxacillin and gentamicin combination showed superior response compared to crystalline penicillin and gentamicin.
• Only 30.3% required prolonged intercostal drainage; mortality rate was 12.1%.
• Factors influencing recovery included age, antibiotic choice, and nutritional status.

Conclusions:

• Early diagnosis and appropriate antibiotic therapy, considering pathogen profile and patient factors, are key to successful empyema management.
• The combination of cloxacillin and gentamicin offers a promising therapeutic option for pediatric empyema.
• Further research into risk factors and long-term sequelae, such as bronchiectasis, is warranted.
