Background Candidemia and invasive candidiasis are major causes of morbidity and mortality among critically ill patients and neonates. Every year more than 250,000 people develop invasive candidiasis, causing more than 50,000 deaths worldwide. Candida albicans is the most frequently isolated species worldwide. However, species distribution, epidemiology, and resistance have changed. C. parapsilosis complex (CPC), which has a global rate of fluconazole (FCZ) resistance range between 2 and 5% and has been related to echinocandins resistance, is the second most isolated species at Fundación Valle del Lili (FVL). We aim to describe the clinical and microbiological characteristics of fungal infections by C. parapsilosis, and determine FCZ resistance rates. Methods An observational prospective study was conducted. The study included patients with CPC isolations attended at FVL from 2016 to 2017. The strains were identified by mass spectrometry (MALDI TOF® Bruker, Biotyper 3.1). Minimal inhibitory concentrations (MIC) were determined by broth microdilution (M27 A3 CLSI). Statistical univariate analysis was performed; Differences between resistant cases and nonresistant cases were assessed through U Mann–Whitney test, Pearson chi-squared test or Fisher exact test. Results 55 patients had CPC isolations during the study period: 18 newborns, 13 children, and 24 adults. Most isolations were from blood cultures (n = 31) (14 of them newborns), bronchoalveolar lavage (n = 9), peritoneal fluid (n = 8), and catheter tips (n = 3). The resistance was 36%. 52 strains were C. parapsilosis ss, of them, 20 were FCZ resistant; 3 strains were C. orthopsilosis, all of them FCZ sensitive. The MIC50 = 1 µg/mL and MIC90 = 16 µ/mL. Patients with previous antifungal treatment had a higher risk of FCZ resistance (RR: 2.14, 95% IC 1.07–4.26). The mortality brute rate was 30%, patients with diabetes and renal failure death risk (RR: 3.1, 95% CI: 1.4 – 6.9) and (RR: 2.96, 95% CI: 1.4 – 6.4), respectively. Candidemia was present in 50% of deaths among children with parenteral nutrition. Conclusion Fluconazole resistance in CPC has increased in the last decade. Newborns receiving parenteral nutrition had a higher proportion of CPC fungemia; we also found higher mortality rates among this population. Disclosures All authors: No reported disclosures.
