Caspofungin therapy in prosthetic valve endocarditis and candidemia due to itraconazole-resistant Candida glabrata (Nakaseomyces glabratus): A case report

A 13-year-old boy developed a serious fungal infection on his replacement heart valve after recent surgery. The fungal infection was caused by a type of yeast called Candida glabrata that was resistant to the initial antifungal medication. After testing revealed resistance and biofilm formation, doctors switched to caspofungin, a stronger antifungal drug, and the patient recovered successfully.

The efficacy of luliconazole and caspofungin on planktonic and biofilm of Candida albicans from different sources

Candida albicans, a common yeast infection organism, can form tough protective structures called biofilms that resist antifungal medications. This study tested two antifungal drugs (luliconazole and caspofungin) against Candida in both regular form and biofilm form. The results showed that while these drugs work well against regular Candida cells, they are much less effective against biofilms, which require 15-171 times higher doses to be inhibited. The strongest biofilms came from vaginal infections, suggesting that different infection types may require different treatment approaches.
