Background: Invasive fungal infection (IFI) has increased in recent years due to there being a greater number of risk factors. IFI caused by Candida is the most frequent, and although Candida albicans is the most isolated species, there is currently a decrease of C. albicans and an increase of other species of the genus.
Aims: To analyse the epidemiology, risk factors, and antifungal susceptibility of blood culture isolates of non-C.albicans Candida species in our hospital in the last 12years.
Methods: A retrospective study was conducted on 107 patients with candidaemia admitted to our hospital. Candida isolates susceptibility to fluconazole, itraconazole, voriconazole, amphotericinB, 5-fluorocytosine, caspofungin, micafungin, and anidulafungin was determined by means of a microdilution technique (Sensititre Yeast One; Izasa, Spain).
Results: From a total of 109 strains, 59 belonged to non-C. albicans Candida species: 25 Candida parapsilosis complex, 14 Candida glabrata complex, 13 Candida tropicalis, 4 Candida krusei, 1 Candida lipolytica, 1 Candida membranaefaciens, and 1 Candida pulcherrima. The most common risk factor in adults and children was catheter use. It was observed that 8.5% of those non-C.albicans strains were resistant to fluconazole.
Conclusions: The results of this work confirm that it is necessary to know the epidemiology of non-C.albicans Candida species, the in vitro susceptibility of the species involved, and the main risk factors, especially in patients with predisposing conditions.
