Refractory fungal infection: Three case reports highlighting good practice

mycolabadmin

This case series examines three patients with serious fungal infections that did not respond well to standard antifungal treatments. The cases demonstrate how fungi can develop resistance to common antifungal drugs like azoles, making infections harder to treat. The authors emphasize that accurate identification of the fungus, testing its sensitivity to drugs, monitoring drug levels in the blood, and careful use of antifungal medications are essential for successfully treating these difficult infections.

Pyrvinium Pamoate Synergizes with Azoles in vitro and in vivo to Exert Antifungal Efficacy Against Candida auris and Other Candida Species

Researchers tested a combination of an old antiparasitic drug called pyrvinium pamoate with common antifungal medications called azoles against dangerous drug-resistant fungal infections. While pyrvinium pamoate alone was not very effective, when combined with azoles it significantly improved the treatment of Candida auris infections. Tests in insect larvae showed that the combination improved survival rates better than using azoles alone, suggesting a promising new treatment approach for serious fungal infections.

Loss of the Aspergillus fumigatus spindle assembly checkpoint components, SldA or SldB, generates triazole heteroresistant conidial populations

This research reveals that disabling certain cell division checkpoint proteins in the fungus Aspergillus fumigatus creates populations resistant to triazole antifungal drugs. The resistant fungal cells appear to have abnormal amounts of genetic material, suggesting that loss of these checkpoint controls allows cells with extra chromosomes to survive drug exposure. This discovery provides new insight into how dangerous fungal infections can develop resistance to our most important antifungal treatments.

Candida albicans bloodstream infections are comprised of diverse populations of strains, including antifungal tolerant strains that emerge during treatment failure

mycolabadmin

Researchers found that Candida albicans bloodstream infections contain multiple different strains, not just one strain as previously thought. Some strains are more tolerant to antifungal medications like micafungin, and when treatment is started, the drug-tolerant strains can be eliminated while drug-sensitive strains increase in number. This discovery suggests that treatment failures may occur because pre-existing drug-resistant strains are selected for during treatment.
