Candida auris Urinary Tract Infections and Possible Treatment.

Candida auris is a globally emerging pathogen that has been identified in urinary tract infections (UTIs) worldwide. The novel pathogen is characterized by common misidentification, difficult eradication, and multidrug resistance. To date, there is a paucity of data to guide the optimal management of C. auris UTIs. This review provides an overview of C. auris as an etiologic agent of UTIs, a comprehensive review of published data on C. auris UTIs, and a proposed treatment algorithm based on patient clinical status, the presence or absence of clinical infection, comorbidities, infection, and therapy history. Echinocandin and liposomal amphotericin B are recommended as first-line agents for most patients with C. auris isolated in the urine, with a focus on infection control measures and appropriate follow-up criteria. A variety of combination therapies, flucytosine, and amphotericin B bladder irrigations are offered as potential alternatives in the event of infection persistence or recurrence. The treatment approach centers on the aggressive treatment of C. auris in most patients, with the goal of preventing subsequent invasive spread, multi-drug resistance, and ultimate mortality. Published literature on C. auris urinary isolation and treatment is imperative for the future evolution of evidence-based treatment recommendations for this unique pathogen of concern.
