    Candida urinary tract infections in adults
    (SPRINGER, 2020) ODABAŞI, ZEKAVER; Odabasi, Zekaver; Mert, Ali
    Candiduria is commonly seen in hospitalized patients and most of the patients are asymptomatic, but it may be due to cystitis, pyelonephritis, prostatitis, epididymo-orchitis or disseminated candidiasis. Major risk factors are diabetes mellitus, indwelling urinary catheters, use of broad-spectrum antibiotics, urinary obstruction, and admission to intensive care units. Candida urinary tract infections can be caused by hematogenous spread following candidemia, or retrograde route via the urethra. The presence of Candida species in urine in asymptomatic patients does not warrant antifungal therapy except neutropenic patients, very low-birth-weight infants and patients undergoing urologic procedures. Fluconazole is the treatment of choice for symptomatic infections, it achieves high urinary levels. The other azole antifungals and echinocandins do not reach sufficient urine levels. Amphotericin B deoxycholate is the alternative antifungal agent if fluconazole can not be used because of resistance, allergy or failure.

    Differences in beta-glucan levels in culture supernatants of a variety of fungi
    (OXFORD UNIV PRESS, 2006-01) ODABAŞI, ZEKAVER; Odabasi, Zekaver; Paetznick, Victor L.; Rodriguez, Jose R.; Chen, Enuo; McGinnis, Michael R.; Ostrosky-Zeichner, Luis
    (1 -> 3)-beta-d-glucan is a well known cell wall constituent of fungal isolates that can be detected by assays in vivo and in vitro. Previous studies have shown that different fungal isolates may show different levels of reactivity with an assay for beta glucan. In this study we evaluated the in vitro reactivity of 127 clinical fungal isolates belonging to 40 different genera, with the Glucatell (TM) assay. The majority of the fungal isolates released high levels of beta glucan. Beta glucan test reactivity appears to be species-specific and this may reflect the beta glucan content of the organism.
