Abstract:
Systemic fungal infections are being recognized with increasing frequency in extremely premature neonates. We report two such infants with late-onset mixed infection with Staphylococcal species and unusual fungi. These cases are of interest in view of recent reports on the interaction of Staphylococcal cell wall components and neutrophils, as damaged skin sites could form a nidus and portal of entry for saprophytic fungal pathogens. It is also important to consider fungal infection as a possibility in sick premature infants with necrotic skin lesions even when the systemic signs have an alternative explanation with ongoing bacteremia.
Insights
Systemic fungal infections are increasingly seen in premature infants. This study highlights two cases of mixed Staphylococcal and fungal infections, emphasizing the need for fungal infection consideration in neonates with skin lesions.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Mycology
Background:
- Systemic fungal infections are a growing concern in extremely premature neonates.
- Staphylococcal infections and fungal pathogens can co-occur, posing diagnostic challenges.
Observation:
- Two cases of extremely premature neonates presented with late-onset mixed infections.
- Infections involved Staphylococcal species and unusual fungi.
Findings:
- Damaged skin may serve as an entry point for fungal pathogens, potentially exacerbated by Staphylococcal interactions.
- Fungal infection should be considered in sick premature infants with necrotic skin lesions, even with concurrent bacteremia.
Implications:
- Early recognition and consideration of fungal infections are crucial for managing sick premature infants.
- Understanding pathogen interactions can inform preventative strategies and treatment protocols for neonatal sepsis.
