Invasive fungal infections in newborns and current management strategies

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Pediatric Critical Care

Background:

• Invasive fungal infections, particularly Candida, are a significant cause of late-onset sepsis in very low birth weight infants (<1500g).
• Invasive candidiasis in extremely low birth weight infants (<1000g) carries a high mortality rate (30%) and leads to neurodevelopmental impairment in over half of survivors.

Purpose of the Study:

• To highlight the diagnostic challenges and necessary evaluations for invasive fungal infections in neonates.
• To outline current treatment mainstays and recommended preventive strategies for invasive candidiasis in high-risk infant populations.

Main Methods:

• Review of current literature and clinical guidelines regarding invasive fungal infections in neonates.
• Emphasis on clinical suspicion, comprehensive multisystem evaluation for diagnosis, and complication detection.

Main Results:

• Amphotericin B deoxycholate remains the primary treatment for invasive fungal infections in newborns.
• Preventive measures include early enteral feeding with human milk, minimizing catheter use, and avoiding antacids, steroids, and broad-spectrum antibiotics.
• Fluconazole prophylaxis is recommended for neonates <1000g in units with >5% baseline invasive candidiasis rates.

Conclusions:

• Prompt diagnosis and management of invasive fungal infections are critical for reducing mortality and neurodevelopmental sequelae in vulnerable neonates.
• Targeted preventive strategies, including judicious use of fluconazole prophylaxis, can significantly impact the incidence of invasive candidiasis in high-risk neonatal populations.
