Neonatal septicaemia caused by vancomycin resistant enterococcus faecium-a case report

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Microbiology

Background:

• Neonatal bacterial sepsis presents a significant challenge, contributing to substantial morbidity and mortality.
• Enterococci account for approximately 10% of neonatal bacteremia and septicemia cases.
• The rise of vancomycin-resistant Enterococci (VRE) poses a critical threat due to limited therapeutic options and elevated mortality rates.

Observation:

• A premature, low-birth-weight male infant was admitted to the Neonatal Intensive Care Unit (NICU) with respiratory distress and meconium aspiration.
• Despite supportive care, the infant's condition deteriorated, leading to death on the fifth day of life.
• Blood cultures revealed the presence of vancomycin-resistant Enterococcus faecium (VRE) with a minimum inhibitory concentration (MIC) of ≥ 256 μg/ml.

Findings:

• The isolated Enterococcus faecium strain exhibited the Van A phenotype, confirming high-level vancomycin resistance.
• Automated Vitek system identification corroborated the species and resistance phenotype.
• The case underscores the potential for VRE to cause severe neonatal sepsis in a tertiary care setting.

Implications:

• This case highlights the critical need for early detection and management of VRE infections in vulnerable neonatal populations.
• The findings emphasize the importance of antimicrobial stewardship programs to combat the spread of antibiotic resistance.
• Further research into effective treatment modalities for neonatal VRE sepsis is warranted to improve patient outcomes.
