[Candida infections in the elderly].

Candida infections of the skin, mucous membranes as well as of internal organs may be more frequent and more serious in the elderly. There are several biological reasons for this, for example, alterations in the immune system. Whereas Candida albicans remains the major pathogen, there has been a relative increase of Candida glabrata infections. This species is associated with higher mortality. Furthermore, C. glabrata is in general less susceptible to fluconazole, so that this drug does not represent the agent of first choice for the treatment of yeast infections. The choice of the antimycotic agent must take into consideration their inherent side effects and interaction profiles; echinocandins play a particular role in the treatment of yeast infections in the elderly. These drugs have low toxicities, low potential for interactions with co-medications, as well as broad and good activities against yeasts.
