REVIEW
Oleg Epelbaum, Rachel Chasan
Candidemia presents several challenges to the intensive care unit (ICU) community. Recognition and treatment of this infection is frequently delayed, with dramatic clinical deterioration and death often preceding the detection of Candida in blood cultures. Identification of individual patients at the highest risk for developing candidemia remains an imperfect science; the role of antifungal therapy before culture diagnosis is yet to be fully defined in the ICU. The absence of well-established molecular techniques for early detection of candidemia hinders efforts to reduce the heavy clinical and economic impact of this infection...

Candida albicans is the most common fungus in the human intestinal microbiota but not in mice. To make a murine sepsis model more closely resemble human sepsis and to explore the role of intestinal C. albicans, in the absence of candidemia, in bacterial sepsis, live- or heat-killed C. albicans was orally administered to mice at 3h prior to cecal ligation and puncture (CLP). A higher mortality rate of CLP was demonstrated with Candida-administration (live- or heat-killed) prior to CLP. Fecal Candida presented only in experiments with live-Candida administration...

The risk of developing candidemia after candiduria is reportedly very low, but it has not been adequately investigated. The aim of this study was to examine the molecular relatedness between Candida strains isolated from adult patients with candidemia and concomitant candiduria in association with the clinical characteristics of the cases. All episodes of candidemia occurring in a tertiary care academic hospital during a 5-year period were recorded prospectively. Patients with episodes of candiduria occurring two weeks preceding to or one week following a positive for Candida blood culture were included in the study...

Serious infections caused by Candida yeasts are frequent in the hospital population. Due to differences in species distribution and antifungal susceptibility testing depending on the geographic area and the type of patient, it is important to study the epidemiology of each institution. For this purpose, we conducted a retrospective, descriptive study on the occurrence of candidemia in the Children's Hospital "Superiora Sor María Ludovica" of the city of La Plata. In a 6-year period (2010-2015), 177 candidemia episodes were recorded...

BACKGROUND: Blood culture is the gold standard diagnostic method in candidemia in spite of long result time and low sensitivity rate. Early diagnosis is crucial for management of candidemia because a delay in treatment is related with increased mortality. We aimed to evaluate the direct applicability of antifungal susceptibility testing methods from positive blood culture bottles to save at least 24 hours. METHODS: Blood culture bottles were inoculated with 62 Candida isolates...

OBJECTIVE: To investigate the epidemiology, treatment, length of stay (LOS) and costs for neonatal and pediatric inpatients with invasive candidiasis (IC). METHODS: The Cerner Health Facts Database was used to assess inpatients (2005-2014) identified by positive blood or cerebrospinal fluid (CSF) Candida cultures. Log-transformed LOS and cost were examined in candidemia-only patients (n= 191) using multivariable linear regression. RESULTS: 202 patients had a positive culture (blood: n = 192; CSF: n = 10; both: n = 2)...

BACKGROUND: Cost-effectiveness studies of echinocandins for the treatment of invasive candidiasis, including candidemia, are rare in Asia. No study has determined whether echinocandins are cost-effective for both Candida albicans and non-albicans Candida species. There have been no economic evaluations that compare non-echinocandins with the three available echinocandins. This study was aimed to assess the cost-effectiveness of individual echinocandins, namely caspofungin, micafungin, and anidulafungin, versus non-echinocandins for C...

BACKGROUND AND PURPOSE: Candida species are considered a common cause of fungal blood stream infections, which are associated with considerable mortality and morbidity rates, especially in the admitted and immunocompromised patients. Despite the increase in new and available antifungal agents, the emergence of resistant strains is growing. Regarding this, the aim of the present study was to assess the fungal epide-miology of candidemia and the antifungal susceptibility patterns against five current antifungal agents among the patients with prolonged fever, who were admitted to Beheshti Educational Hospital, Kashan, Iran...

Candida pararugosa is a yeast that has been previously isolated in various human specimens. The first reported isolation was from human feces in 1998, with subsequent reports of positive cultures from the oral cavity where it was thought to represent colonization rather than true infection. Though it has been isolated from other human sites, its clinical significance and manifestations are poorly characterized. We report the case of a 39-year-old woman on parenteral hyperalimentation who developed post abdominal surgery sepsis and surgical wound necrotizing fasciitis...

Candida species bloodstream infection such as candidemia remains a significant with high morbidity and mortality. Bloodstream infections caused by Candida species is often associated with the ability of Candida to form biofilms by using medical devices, such as central venous catheters. Non-albicans Candida species are increasing gradually in recent clinical practices. One of the Candida species, C. tropicalis, is likely to form biofilms and is also an independent risk factor with high morbidity and mortality in hospitalized patients...

In this review, we describe the epidemiology and clinical significance of resistance in Candida spp. and other non-Cryptococcus yeasts. The rise in echinocandin resistance, azole resistance and cross-resistance to ≥2 antifungal classes (multi-drug resistance: MDR) has been a worrisome trend, mainly in US large tertiary and oncology centers, particularly as it relates to C. glabrata. C. kefyr is also a concern, as it can be resistant to echinocandins and polyenes, especially in patients with hematologic malignancies...

Pathogenic microbes can recruit to their cell surface human proteins that are components of important proteolytic cascades involved in coagulation, fibrinolysis and innate immune response. Once located at the bacterial or fungal surface, such deployed proteins might be utilized by pathogens to facilitate invasion and dissemination within the host organism by interfering with functionality of these systems or by exploiting specific activity of the bound enzymes. Aim of the study presented here was to characterize this phenomenon in Candida parapsilosis (Ashford) Langeron et Talice - an important causative agent of systemic fungal infections (candidiases and candidemias) in humans...

The aims of this study were to evaluate the epidemiology of nosocomial candidemia in a large teaching hospital in Brescia, Italy, and the in vitro antifungal susceptibility of isolates. We analyzed 196 isolates causing fungemia in patients admitted in our hospital, between January 2009 and December 2015. Strains were identified by VITEK 2 and MALDI-TOF MS. MICs were determined by Sensititre Yeast OneTM. The resistance was defined by using the revised CLSI breakpoints/epidemiological cutoff values to assign susceptibility or wild type to systemic antifungal agents...

BACKGROUND: We investigated the clinical characteristics and risk factors for mortality in adults with persistent candidemia. METHODS: All patients ≥18 years old with candidemia in two Korean tertiary hospitals from 2007 to 2014 were investigated. Persistent candidemia was defined as isolation of the same Candida species ≥5 days after initiation of antifungal therapy. Non-persistent candidemia was defined as candidemia persisting for ≤3 days after initiation of antifungal therapy...

Sera from candidemic and non-candidemic subjects were examined for antibodies against the cell wall β1,3- and β1,6-glucans, as well as the β-glucan-associated protein MP65 of Candida species. Although antibodies against each of the above components were detected in all subjects, candidemic patients had lower antibody titers against β1,3-glucan, but higher antibody titers against β1,6-glucan and MP65, than non-candidemic subjects. The elevated levels of anti-β1,6-glucan and -MP65 antibodies found in candidemic patients were independent on the patient risk category, APACHE II score, presence of co-morbidities, β1,3-glucanemia level, Candida isolate, and antifungal treatment...

BACKGROUND: Invasive fungal infections remain a leading cause of morbidity and mortality among liver transplant recipients (LTRs). In this patient population, invasive Candida infections (ICIs) account for the large majority of cases. To date, only small studies and case-series analysing clinical presentation and risk factors for mortality in LTRs with ICIs are available. METHODS: We performed a retrospective multicenter multinational study in 10 centers in Europe and Brazil...

Fungal Candida species are commensals present in the mammalian skin and mucous membranes. Candida spp. are capable of breaching the epithelial barrier of immunocompromised patients with neutrophil and cell-mediated immune dysfunctions and can also disseminate to multiple organs through the bloodstream. Here we examined the action of innate defense regulator 1018 (IDR-1018), a 12-amino-acid-residue peptide derived from bovine bactenecin (Bac2A): IDR-1018 showed weak antifungal and antibiofilm activity against a Candida albicans laboratory strain (ATCC 10231) and a clinical isolate (CI) (MICs of 32 and 64 μg · ml(-1), respectively), while 8-fold lower concentrations led to dissolution of the fungal cells from preformed biofilms...
