A novel approach to candidemia? The potential role of checkpoint inhibition.

Infections with Candida spp. cause significant morbidity and mortality despite intensive treatment with antifungal agents. Novel treatment options are urgently needed. Predominately immunocompromised patients are affected. This warrants the conclusion that strengthening host immunity may have the potential to improve outcome. Recent studies imply a potential benefit of checkpoint inhibition reversing hyporesponsiveness of innate and adaptive immunity during invasive fungal infections and invasive candidiasis in particular. We here give a brief overview of first preclinical data in vitro and in vivo and clinical evidence in selected cases.
