732. Evaulation of Micafungin Treatment at Pediatric Patients: A cross-sectional Study from Tertiary Pediatric Centre

Abstract Background Micafungin is one of three currently available echinocandin for treatment of candidiasis and candidemia. Methods Children who were treated for micafungin for possible or proven invasive Candidia infection between May 2017 and October 2019 were included. Results In this cross-sectional study, totally 78 children with a median age of 3 months (8 days -17 years), 50 (64.1%, F/M: 0.56) male were included. Thirty four (43.6%) patients were neonate, 26 (76 %) of them were premature. Thirty seven patients (47.4%) received micafungin for candidemia and 41 (52.6%) patients received micafungin empirically for IC. Twelve (32.4%) Candida spp cultured were C. albicans, the rest twenty five (67.6%) Candida spp were non-albicans Candida spp. The most commonly cultured Candida spp was Candida parapsilosis (C. parapsilosis) (n=13) followed by C. albicans (n=12), C. glabrata (n=3), C. tropicalis (n=3), C. guilliermondii (n=3), C. krusei (n=2) respectively. Resistance rate of C. parapsilosis (n=13) isolates to fluconazole, voriconazole, amphotericin B, caspofungin, micafungin were as follows respectively; 66.7%, 100%, 69.2%, 90.9%, 37.5% respectively. Resistance rate of C. albicans (n=11) isolates to fluconazole, voriconazole, amphotericin B, caspofungin, micafungin were as follows respectively; 50%, 50%, 12.5%, 42.9%, 0% respectively. None of the C. tropicalis, C. guilliermondii and C. krusei isolates were resistant to micafungin. Culture negativity could not be achieved at the end of 14th day of micafungin treatment in the 15 (16.9%) candidemia episodes. The most commonly isolated Candida spp in patients with treatment failure was C. parapsilosis (n=7), the other species were; C. albicans (n=5), C. guilliermondii (n=1), C. tropicalis (n=1) and C. tropicalis and C. guilliermondii coinfection (n=1) respectively. Median serum AST, ALT and creatinin levels didn’t increase during and at the end of micafungin therapy. None of these patients had experienced an anormal kidney or liver function tests due to micafungin usage. Characteristics of patients who received micafungin.and cultured Candida spp Antifungal resistance patterns of Candida spp. Laboratory change before and after micafungin treatment Conclusion Increase in fluconazole resistant Candida spp makes micafungin a reasonable and effective choice for suspected or proven invasive candidiasis Disclosures All Authors: No reported disclosures
