Clinically significant azole cross-resistance in Candida isolates from HIV-positive patients with oral candidosis

Abstract

Clinically significant cross-resistance to other azoles may occur in fluconazole-resistant isolates of C. albicans, although initially most isolates are not cross-resistant and the detection of cross-resistant isolates is associated with a history of greater prior azole exposure. Patients who have been treated for fluconazole-resistant candidosis for longer and with greater cumulative doses of itraconazole solution tend to become infected with increasingly cross-resistant isolates of C. albicans.
