Background: In intensive care units, invasive fungal infections have become more common, particularly among immunocompromised patients. Early identification and starting the treatment of those patients with antifungal therapy is critical for preventing unnecessary use of toxic antifungal agents. Objective: The aim of this research is to determine which common fungi cause invasive fungal infection in immunocompromised patients, as well as their antifungal susceptibility patterns in vitro, in Assiut University Hospitals. Methodology: This was a hospital based descriptive study conducted on 120 patients with clinical suspicion of having fungal infections admitted at different Intensive Care Units (ICUs) at Assiut University Hospitals. Direct microscopic examination and inoculation on Sabouraud Dextrose Agar (SDA) were performed on the collected specimens. Isolated yeasts were classified using phenotypic methods such as chromogenic media (Brilliance Candida agar), germ tube examination, and the Vitek 2 system for certain isolates, while the identification of mould isolates was primarily based on macroscopic and microscopic characteristics. Moulds were tested in vitro for antifungal susceptibility using the disc diffusion, and yeast were tested using Vitek 2 device cards. Results: In this study, 100 out of 120 (83.3%) of the samples were positive for fungal infection. Candida and Aspergillus species were the most commonly isolated fungal pathogens. The isolates had the highest sensitivity to Amphotericin B (95 %), followed by Micafungin (94 %) in an in vitro sensitivity survey. Conclusion: Invasive fungal infections are a leading cause of morbidity and mortality in immunocompromised patients, with Candida albicans being the most frequently isolated yeast from various clinical specimens; however, the rise in resistance, especially to azoles, is a major concern.

Initiation Of Therapy

Invasive fungal infections (IFIs) have seen considerable increase in pediatric intensive care units over the past several decades. IFIs are predominantly caused by Candida species, and candidemia is the third most common cause of healthcare-associated bloodstream infections (BSIs) in children. IFIs are opportunistic infections that affect pediatric patients in critical care resulting in significant morbidity and mortality especially in those with a compromised immune system. IFIs are the leading cause of death in children with comorbidities such as immunosuppression, and pediatric ICU admission has been shown to be an independent risk factor for mortality. Management of IFI and fungal sepsis is broad and encompasses several key components that include prompt initiation of therapy and rapid source identification and control. This study reviews important antifungals in the pediatric critical care setting including the pharmacologic properties, antifungal spectrum, adverse effects, and clinical uses of agents belonging to the four major classes of antifungals—the polyenes, azoles, echinocandins, and pyrimidine analogue flucytosine. The polyenes and azoles are the most often used classes of antifungals. The echinocandins are a relatively newer class of antifungal agents that offer excellent Candida activity and are currently recommended as the first-line therapy for invasive candidiasis.
