Young infant sepsis: aetiology, antibiotic susceptibility and clinical signs

Area of Science:

• Global Health
• Pediatrics
• Infectious Diseases

Background:

• Young infant mortality remains a significant global health challenge, particularly in low- and middle-income countries (LMICs).
• Severe infections are a leading cause of death in this vulnerable population.
• Effective management of infections in young infants is critical for achieving child survival goals.

Purpose of the Study:

• To review current evidence on severe infections in young infants in LMICs.
• To describe common pathogens, their antibiotic susceptibility, and the utility of clinical signs in diagnosing severe bacterial illness.
• To inform the development of evidence-based clinical guidelines for reducing infant mortality.

Main Methods:

• Systematic review of existing evidence from LMICs concerning young infant infections.
• Analysis of reported pathogens, antibiotic resistance patterns, and diagnostic clinical signs.
• Identification of research gaps, particularly in community-based settings.

Main Results:

• Pathogen prevalence in young infant infections varies over time and across different settings.
• Limited large-scale studies exist outside urban centers, and many focus on hospital-acquired infections.
• Clinical signs show variable utility in identifying severe bacterial illness.

Conclusions:

• Current knowledge, despite limitations, can guide prompt and appropriate therapy for young infant infections.
• Minimizing multidrug-resistant bacteremia requires better data on local microbial patterns and antibiotic use.
• Improved country-level data is essential for developing localized, evidence-based clinical guidelines to reduce infant mortality.
