Invasive Candida Infections in Neonates after Major Surgery: Current Evidence and New Directions

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Mycology

Background:

• Invasive Candida infections (ICIs) pose significant mortality and morbidity risks in neonatal intensive care units (NICUs).
• Neonates in NICUs face high ICI risk due to factors like broad-spectrum antibiotics, invasive devices, and immature immune systems.
• Previous surgery is a notable risk factor for ICIs in this vulnerable population.

Purpose of the Study:

• To review the prevalence of prior surgery in neonates diagnosed with invasive Candida infections.
• To provide a comprehensive overview of risk factors, fungal species, epidemiology, diagnosis, and treatment of neonatal ICIs.
• To synthesize current knowledge on antifungal prophylaxis and treatment strategies for neonatal candidiasis.

Main Methods:

• Systematic review of 19 published studies focusing on neonatal ICIs and prior surgery.
• Analysis of risk factors, including surgical history, fungal colonization, and immune status.
• Compilation of data on Candida species, epidemiology, diagnostic methods, and therapeutic interventions.

Main Results:

• The review summarizes the prevalence of previous surgery among neonates with ICIs across 19 studies.
• Identified key risk factors for ICIs post-major surgery, fungal colonization patterns, and host defense mechanisms.
• Detailed the epidemiology, economic impact, diagnostic approaches, and current treatment guidelines for neonatal candidiasis.

Conclusions:

• Invasive Candida infections remain a critical concern in neonatal intensive care, with prior surgery being a significant risk factor.
• A thorough understanding of risk factors, early diagnosis, and appropriate antifungal strategies are essential for improving outcomes in neonates with ICIs.
• Further research into innate defense mechanisms and targeted antifungal therapies can enhance the management of neonatal candidiasis.
