Neonatal and pediatric sepsis: Microbiological insights, diagnostic innovations, and antimicrobial challenges
Year: 2025
Type: article
Abstract: Neonatal and pediatric sepsis remains a major global health concern, contributing significantly to morbidity and mortality among children under 5 years of age. The clinical and microbiological characteristics of sepsis differ markedly in neonates and children, necessitating tailored diagnostic and treatment approaches. This mini-review explores the evolving microbiological landscape, recent advancements in diagnostic methodologies, and challenges posed by antimicrobial resistance (AMR) in managing neonatal and pediatric sepsis. Emerging pathogens, including multidrug-resistant Gram-negative bacilli and fungal organisms, are reshaping the epidemiology of sepsis. Innovations in molecular diagnostics, including polymerase chain reaction-based platforms, next-generation sequencing, and artificial intelligence-integrated tools, are revolutionizing early pathogen detection and resistance profiling. However, implementation gaps persist, particularly in low- and middle-income countries. Therapeutic challenges are compounded by limited pediatric data on newer antimicrobials and rising AMR rates. Infection prevention strategies, especially in intensive care units, are crucial to outbreak containment. An integrated approach combining microbiological surveillance, rapid diagnostics, and antimicrobial stewardship is critical for improving sepsis outcomes. Future research should focus on context-specific implementation of diagnostic tools and optimizing treatment strategies for resource-limited settings.
