Despite the relatively small number of reported cases, the Nipah virus remains a major clinical and public health concern because of its high mortality, capacity for person-to-person transmission, lack of approved antiviral treatment, and potential for amplification within healthcare settings. For clinicians, the major challenge lies in early recognition of a disease that initially presents with nonspecific febrile symptoms but may rapidly progress to severe encephalitis, acute respiratory distress syndrome, or both.

This prospective observational pilot study examined consecutive cases of guideline-defined catheter-related candidemia (CRC) diagnosed in medical wards at two Italian hospitals in 2025. All subjects initially received short-acting echinocandin therapy alongside catheter removal for source control. Upon meeting predefined clinical and microbiological stability criteria, patients were administered a single dose of rezafungin on day 7.

Secondary endpoints encompassed reductions in hospital length of stay, relapse rates, mortality, and adverse drug events. Seven patients received rezafungin as consolidation therapy. The cohort was characterized by advanced age and a high comorbidity burden. Microbiological eradication was achieved in all cases. No drug-related adverse events, relapses, or deaths were observed at 30- and 90-day follow-up. The median estimated decrease in hospital stay was four days, translating to 28 bed-days saved. This real-world pilot cohort demonstrated that a stepwise antifungal strategy incorporating rezafungin following initial echinocandin therapy is feasible, well-tolerated, and associated with favorable short-term outcomes.

In order to prevent potential B19V transmission, the implicated donors were recalled for clinical and virological follow-up for one year.
