Insights

Fluconazole prophylaxis in premature infants led to more fluconazole-resistant Candida parapsilosis. Careful use of antifungal prophylaxis and monitoring for drug resistance in fungal infections are recommended.

Area of Science:

  • Neonatal Intensive Care
  • Mycology
  • Infectious Diseases

Background:

  • Nosocomial fungal infections pose a significant threat to premature infants.
  • Antifungal prophylaxis is used to prevent these infections.
  • Candida parapsilosis is a common cause of fungal infections in neonates.

Purpose of the Study:

  • To investigate the impact of a 4-year fluconazole prophylaxis program on antifungal resistance in Candida parapsilosis.
  • To assess the emergence of fluconazole resistance in a premature animal neonatal intensive care unit.

Main Methods:

  • Retrospective analysis of fungal isolates over a 4-year period.
  • Monitoring of Candida parapsilosis occurrence and fluconazole susceptibility.
  • Study conducted in a premature animal neonatal intensive care unit.

Main Results:

  • An increased occurrence of fluconazole-resistant Candida parapsilosis was observed.
  • The 4-year period of antifungal prophylaxis correlated with this increase.
  • Fluconazole resistance emerged in the studied population.

Conclusions:

  • Fluconazole prophylaxis in premature infants requires cautious implementation.
  • Antifungal prophylaxis may lead to the selection of resistant fungal strains.
  • Regular evaluation of fungal isolates for drug resistance is crucial in settings with prophylaxis programs.

Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
