Introduction:
Sepsis is a systemic immune dysregulation syndrome triggered by secondary infection in the host, with diagnosis based on the updated Phoenix criteria and characterized by multi-organ failure as its core pathological manifestation. It is a significant global health challenge due to its increasing incidence and high mortality rates. Recent advancements in biomarker research provide promising tools for improving early diagnosis and timely intervention, essential for better patient outcomes.
Areas Covered:
This review examines the latest developments in pediatric sepsis biomarkers, categorized by inflammation, metabolism, organ damage, and non-coding RNAs (miRNAs, LncRNAs). We discuss the advancements in each category, highlighting the integration of diverse biomarkers and advanced technologies to enhance diagnostics, personalize therapy, and improve patient stratification.
Expert Opinion:
Given the limited specificity and sensitivity of current markers like CRP and PCT, multicenter studies are crucial for validating new biomarkers and for developing comprehensive panel markers that combine multiple diagnostic indicators. It is also important to consider the variability in host responses to different pathogens when identifying biomarkers based on host-pathogen interactions. To advance personalized medicine, future research may prioritize the identification of specific diagnostic biomarkers for pediatric sepsis, tailored to different pathogens.
