Background: Recent outbreaks of Candida auris further exemplify that invasive Candida infections are a substantial threat to patients and healthcare systems. Even short treatment delays are associated with higher mortality rates. Epidemiological shifts towards more resistant Candida spp. require careful surveillance. Objectives: Triggered by the emergence of C auris and by increasing antifungal resistance rates the European Confederation of Medical Mycology developed an international Candida Registry (FungiScope™ CandiReg) to allow contemporary multinational surveillance. Methods: CandiReg serves as platform for international cooperation to enhance research regarding invasive Candida infections. CandiReg uses the General Data Protection Regulation compliant data platform ClinicalSurveys.net that holds the electronic case report forms (eCRF). Data entry is supported via an interactive macro created by the software that can be accessed via any Internet browser. Results: CandiReg provides an eCRF for invasive Candida infections that can be used for a variety of studies from cohort studies on attributable mortality to evaluations of guideline adherence, offering to the investigators of the 28 ECMM member countries the opportunity to document their cases of invasive Candida infection. CandiReg allows the monitoring of epidemiology of invasive Candida infections, including monitoring of multinational outbreaks. Here, we describe the structure and management of the CandiReg platform. Conclusion: CandiReg supports the collection of clinical information and isolates to improve the knowledge on epidemiology and eventually to improve management of invasive Candida infections. CandiReg promotes international collaboration, improving the availability and quality of evidence on invasive Candida infection and contributes to improved patient management. © 2019 Blackwell Verlag GmbH

Chronic fungal sinusitis (FS) can cause bone erosion and extend to the sellar region, often misdiagnosed as pituitary tumors or malignancies. We report a 56-year-old immunocompetent female with sphenoid FS presenting as a giant sellar mass compressing the optic chiasm, with normal pituitary function. The surgery successfully resolved her symptoms, and a histological examination confirmed the presence of a fungal hyphal mass. We conducted a literature review of 52 publications on FS cases with bone erosion and inflammatory extension to the sellar region, which included analyses of 67 patients (35 females, mean age 49.6 years, half immunocompetent). The most common symptom was headache (73.1%), followed by visual complaints (71.7%), visual deterioration (40.3%), ophthalmoplegia (38.8%), and visual field defects (13.4%). Symptom duration averaged 4.5 months in 65.7% of cases. Aspergillus was the most frequent (71.6%). Hormonal abnormalities included hypopituitarism (25.4%) and hyperprolactinemia (13.4%). Surgery was performed in 92.5% of patients. Common diagnoses included pituitary abscess (41.8%), fungal granuloma (16.4%), aspergillosis (16.4%) and allergic FS (14.9%). Antifungal therapy was administered in 53.7% of cases. Cure was achieved in 67.2%, while the mortality rate was 10.4%. Early recognition of fungal involvement, supported by a multidisciplinary approach, is essential for the accurate diagnosis and effective treatment. This highlights the need for vigilance to improve the outcomes in similar cases. © 2025 by the authors.

Background: The European Confederation of Medical Mycology (ECMM) collected data on epidemiology, risk factors, treatment, and outcomes of patients with culture-proven candidaemia across Europe to assess how adherence to guideline recommendations is associated with outcomes. Methods: In this observational cohort study, 64 participating hospitals located in 20 European countries, with the number of eligible hospitals per country determined by population size, included the first ten consecutive adults with culture-proven candidaemia after July 1, 2018, and entered data into the ECMM Candida Registry (FungiScope CandiReg). We assessed ECMM Quality of Clinical Candidaemia Management (EQUAL Candida) scores reflecting adherence to recommendations of the European Society of Clinical Microbiology and Infectious Diseases and the Infectious Diseases Society of America guidelines. Findings: 632 patients with candidaemia were included from 64 institutions. Overall 90-day mortality was 43% (265/617), and increasing age, intensive care unit admission, point increases in the Charlson comorbidity index score, and Candida tropicalis as causative pathogen were independent baseline predictors of mortality in Cox regression analysis. EQUAL Candida score remained an independent predictor of mortality in the multivariable Cox regression analyses after adjusting for the baseline predictors, even after restricting the analysis to patients who survived for more than 7 days after diagnosis (adjusted hazard ratio 1·08 [95% CI 1·04–1·11; p<0·0001] in patients with a central venous catheter and 1·09 [1·05–1·13; p<0·0001] in those without one, per one score point decrease). Median duration of hospital stay was 15 days (IQR 4–30) after diagnosis of candidaemia and was extended specifically for completion of parenteral therapy in 100 (16%) of 621 patients. Initial echinocandin treatment was associated with lower overall mortality and longer duration of hospital stay among survivors than treatment with other antifungals. Interpretation: Although overall mortality in patients with candidaemia was high, our study indicates that adherence to clinical guideline recommendations, reflected by higher EQUAL Candida scores, might increase survival. New antifungals, with similar activity as current echinocandins but with longer half-lives or oral bioavailability, are needed to reduce duration of hospital stay.

Molecular typing and antifungal susceptibility testing of 34 clinical Serbian Cryptococcus neoformans isolates from 25 patients was retrospectively performed. Amplified fragment length polymorphism (AFLP) fingerprinting was used for genotyping, whereas a novel real-time PCR was used to determine the mating- and serotype. The antifungals amphotericin B, 5-fluorocytosine, fluconazole, voriconazole, itraconazole and posaconazole were used to determine the antifungal susceptibility profiles. The majority of isolates belonged to genotype AFLP1/VNI (n = 20; 58.8%), followed by AFLP2/VNIV (n = 10; 29.4%), AFLP3/VNIII (n = 3; 8.8%) and AFLP1B/VNII (n = 1; 2.9%). All AFLP1/VNI isolates were mating-serotype αA, the sole AFLP1B/VNII isolate was found to be aA, whereas AFLP2/VNIV harboured serotype D isolates with either the a (n = 2; 5.9%) or α (n = 8; 23.5%) mating-type allele. The isolates (n = 3; 8.8%) that were found to be genotype AFLP3/VNIII had the hybrid mating- and serotype combination aA-αD. In vitro antifungal susceptibility testing showed that all isolates were susceptible to amphotericin B, voriconazole and posaconazole. Low resistance level was observed for fluconazole (n = 1; 2.9%) and 5-fluorocytosine. (n = 2; 5.8%). A large percentage of isolates was found to be susceptible dose dependent to itraconazole (n = 16; 47.1%). AFLP1/VNI was the most common genotype among clinical C. neoformans isolates from immunocompromised patients in Serbia. C. neoformans from HIV-negative patients were significantly less susceptible to 5-fluorocytosine (P < 0.01). Correlation between genotypes and antifungal susceptibility was not observed. © 2014 Blackwell Verlag GmbH.

Despite the increasing of onychomycosis caused by Candida spp., in referent literature, there is still data insufficiency about this nail infection. The objectives of this retrospective study were to determine epidemiological characteristics of Candida onychomycosis, the antifungal susceptibility of isolated species in vitro, and to compare the results of antifungal susceptibility testing with conducted treatment in period from 2011 to the end of March 2015. Out of 761 patients who were underwent clinical and mycological examinations, 137 had Candida species isolated from nails. The dominant species was Candida albicans (C. albicans) (36.59%) followed by C. parapsilosis (23.78%), C. krusei (9.76%), and C. guilliermondii (6.71%). Antifungal susceptibility in vitro testing showed good susceptibility to antimycotics, except C. krusei, which was resistance to fluconazole (FCZ) and isolates of C. tropicalis and C. glabrata which were dose dependent to itraconazole (ITZ) and fluconazole. Evaluation of medical histories determined that combined therapy, which included pulsed systemic regimen of ITZ with topical application of clotrimazole, had better clinical outcomes regarding the proscribed only topical application of clotrimazole. Multidisciplinary approach of dermatologists and mycologists is required in solving the problem of onychomycosis, which is the dominant nail disease. © 2015 Blackwell Verlag GmbH.
