Biofilms formed by Candida albicans bloodstream isolates on catheters are an important clinical problem. Devising chemotherapeutic strategies to treat these in situ is an attractive option. We report here that liposomal amphotericin effectively kills C. albicans biofilms rapidly (12 h) and effectively (>90%) in a dose-dependent manner, whereas caspofungin displays an inverse concentration-dependent effect. This study has implications for considering the effective doses of antifungal agents used for catheter lock therapy.

Cutaneous leishmaniasis (CL) is a tropical disease that can cause chronic lesions and leave life-long scars, leading to social stigmatization and psychological disorders. Using growth factors and immunomodulatory agents that could accelerate wound healing and reduce the scar is highly demanded. Epidermal growth factor (EGF) plays an essential role in wound healing.

Background: The prevention of invasive fungal infections (IFIs) is crucial for paediatric haemato-oncological patients. This study evaluates the clinical efficacy and side-effects of posaconazole and liposomal amphotericin B (L-AmB) as primary prophylaxis.
Materials And Methods: This cohort study included patients aged 3 months to 21 years who received posaconazole or L-AmB (5 mg/kg twice weekly) as prophylaxis from January 2017 to March 2022 at the Hemato-oncological Pediatric Unit, University Hospital of Padua, Italy.
