Candida tropicalis-A systematic review to inform the World Health Organization of a fungal priority pathogens list.

In response to the growing global burden of fungal infections with uncertain impact, the World Health Organization (WHO) established an Expert Group to identify priority fungal pathogens and establish the WHO Fungal Priority Pathogens List for future research. This systematic review aimed to evaluate the features and global impact of invasive candidiasis caused by Candida tropicalis. PubMed and Web of Science were searched for studies reporting on criteria of mortality, morbidity (defined as hospitalization and disability), drug resistance, preventability, yearly incidence, diagnostics, treatability, and distribution/emergence from 2011 to 2021. Thirty studies, encompassing 436 patients from 25 countries were included in the analysis. All-cause mortality due to invasive C. tropicalis infections was 55%-60%. Resistance rates to fluconazole, itraconazole, voriconazole and posaconazole up to 40%-80% were observed but C. tropicalis isolates showed low resistance rates to the echinocandins (0%-1%), amphotericin B (0%), and flucytosine (0%-4%). Leukaemia (odds ratio (OR) = 4.77) and chronic lung disease (OR = 2.62) were identified as risk factors for invasive infections. Incidence rates highlight the geographic variability and provide valuable context for understanding the global burden of C. tropicalis infections. C. tropicalis candidiasis is associated with high mortality rates and high rates of resistance to triazoles. To address this emerging threat, concerted efforts are needed to develop novel antifungal agents and therapeutic approaches tailored to C. tropicalis infections. Global surveillance studies could better inform the annual incidence rates, distribution and trends and allow informed evaluation of the global impact of C. tropicalis infections.

Candida glabrata (Nakaseomyces glabrata): A systematic review of clinical and microbiological data from 2011 to 2021 to inform the World Health Organization Fungal Priority Pathogens List.

Recognising the growing global burden of fungal infections, the World Health Organization (WHO) established an advisory group consisting of experts in fungal diseases to develop a Fungal Priority Pathogen List. Pathogens were ranked based on their research and development needs and perceived public health importance using a series of global surveys and pathogen characteristics derived from systematic reviews. This systematic review evaluates the features and global impact of invasive disease caused by Candida glabrata (Nakaseomyces glabrata). PubMed and Web of Science were searched for studies reporting on mortality, morbidity (hospitalization and disability), drug resistance (including isolates from sterile and non-sterile sites, since these reflect the same organisms causing invasive infections), preventability, yearly incidence, diagnostics, treatability, and distribution/emergence in the last 10 years. Candida glabrata (N. glabrata) causes difficult-to-treat invasive infections, particularly in patients with underlying conditions such as immunodeficiency, diabetes, or those who have received broad-spectrum antibiotics or chemotherapy. Beyond standard infection prevention and control measures, no specific preventative measures have been described. We found that infection is associated with high mortality rates and that there is a lack of data on complications and sequelae. Resistance to azoles is common and well described in echinocandins-in both cases, the resistance rates are increasing. Candida glabrata remains mostly susceptible to amphotericin and flucytosine. However, the incidence of the disease is increasing, both at the population level and as a proportion of all invasive yeast infections, and the increases appear related to the use of antifungal agents.

Epidemiological patterns of candidaemia: A comprehensive analysis over a decade.

BACKGROUND: The prevalence of fungal bloodstream infections (BSI), especially candidaemia, has been increasing globally during the last decades. Fungal diagnosis is still challenging due to the slow growth of fungal microorganisms and need for special expertise. Fungal polymicrobial infections further complicate the diagnosis and extend the time required. Epidemiological data are vital to generate effective empirical treatment strategies. OBJECTIVES: The overall aim of this project is to describe the epidemiology of monomicrobial candidaemia and polymicrobial BSI, both with mixed fungaemia and with mixed Candida/bacterial BSIs. METHODS: We conducted a single-centre retrospective epidemiological study that encompasses 950,161 blood cultures during the years 2010 to 2020. The epidemiology of monomicrobial and polymicrobial candidaemia episodes were investigated from the electronic records. RESULTS: We found that 1334 candidaemia episodes were identified belonging to 1144 individual patients during 2010 to 2020. Candida albicans was the most prevalent species detected in candidaemia patients, representing 57.7% of these episodes. Nakaseomyces (Candida) glabrata and Candida parapsilosis complex showed an increasing trend compared to previous studies, whereas Candida albicans demonstrated a decrease. 19.8% of these episodes were polymicrobial and 17% presented with mixed Candida/bacterial BSIs while 2.8% were mixed fungaemia. C. albicans and N. glabrata were the most common combination (51.4%) in mixed fungaemia episodes. Enterococcus and Lactobacillus spp. were the most common bacteria isolated in mixed Candida/bacterial BSIs. CONCLUSIONS: Polymicrobial growth with candidaemia is common, mostly being mixed Candida/bacterial BSIs. C. albicans was detected in more than half of all the candidaemia patients however showed a decreasing trend in time, whereas an increase is noteworthy in C. parapsilosis complex and N. glabrata.

Increase in candidemia cases and emergence of fluconazole-resistant Candida parapsilosis and C. auris isolates in a tertiary care academic hospital during the COVID-19 pandemic, Greece, 2020 to 2023.

BackgroundThe COVID-19 pandemic and the emergence of Candida auris have changed the epidemiological landscape of candidaemia worldwide.AimWe compared the epidemiological trends of candidaemia in a Greek tertiary academic hospital before (2009-2018) and during the early COVID-19 (2020-2021) and late COVID-19/early post-pandemic (2022-2023) era.MethodsIncidence rates, species distribution, antifungal susceptibility profile and antifungal consumption were recorded, and one-way ANOVA or Fisher's exact test performed. Species were identified by MALDI-ToF MS, and in vitro susceptibility determined with CLSI M27-Ed4 for C. auris and the EUCAST-E.DEF 7.3.2 for other Candida spp.ResultsIn total, 370 candidaemia episodes were recorded during the COVID-19 pandemic. Infection incidence (2.0 episodes/10,000 hospital bed days before, 3.9 during the early and 5.1 during the late COVID-19 era, p < 0.0001), C. auris (0%, 9% and 33%, p < 0.0001) and fluconazole-resistant C. parapsilosis species complex (SC) (20%, 24% and 33%, p = 0.06) infections increased over time, with the latter not associated with increase in fluconazole/voriconazole consumption. A significant increase over time was observed in fluconazole-resistant isolates regardless of species (8%, 17% and 41%, p < 0.0001). Resistance to amphotericin B or echinocandins was not recorded, with the exception of a single pan-echinocandin-resistant C. auris strain.ConclusionCandidaemia incidence nearly tripled during the COVID-19 era, with C. auris among the major causative agents and increasing fluconazole resistance in C. parapsilosis SC. Almost half of Candida isolates were fluconazole-resistant, underscoring the need for increased awareness and strict implementation of infection control measures.

Exploring European Consensus About the Remaining Treatment Challenges and Subsequent Opportunities to Improve the Management of Invasive Fungal Infection (IFI) in the Intensive Care Unit.

BACKGROUND: The global prevalence of invasive fungal infections (IFI) is increasing, particularly within Intensive Care Units (ICU), where Candida spp. and Aspergillus spp. represent the most important pathogens. Diagnosis and management of IFIs becomes progressively challenging, with increasing antifungal resistance and the emergence of rare fungal species. Through a consensus survey focused on assessing current views on how IFI should be managed, the aim of this project was to identify challenges around diagnosing and managing IFIs in the ICU. The current status in different countries and perceived challenges to date amongst a multidisciplinary cohort of healthcare professionals involved in the care of IFI in the ICU was assessed. METHODS: Using a modified Delphi approach, an expert panel developed 44 Likert-scale statements across 6 key domains concerning patient screening and minimal standards for diagnosis of IFIs in ICU; initiation and termination of antifungal treatments and how to minimise their side effects and insights for future research on this topic. These were used to develop an online survey which was distributed on a convenience sampling basis utilising the subscriber list held by an independent provider (M3 Global). This survey was distributed to intensivists, infectious disease specialists, microbiologists and antimicrobial/ICU pharmacists within the UK, Germany, Spain, France and Italy. The threshold for consensus was set at 75%. RESULTS: A total of 335 responses were received during the five-month collection period. From these, 29/44 (66%) statements attained very high agreement (≥ 90%), 11/44 (25%) high agreement (< 90% and ≥ 75%), and 4/44 (9%) did not meet threshold for consensus (< 75%). CONCLUSION: The results outline the need for physicians to be aware of the local incidence of IFI and the associated rate of azole resistance in their ICUs. Where high clinical suspicion exists, treatment should start immediately and prior to receiving the results from any diagnostic test. Beta-D-glucan testing should be available to all ICU centres, with results available within 48 h to inform the cessation of empirical antifungal therapy. These consensus statements and proposed measures may guide future areas for further research to optimise the management of IFIs in the ICU.

Epidemiology and susceptibility of Nakaseomyces (formerly Candida) glabrata bloodstream isolates from hospitalised adults in South Africa.

During 2016-2017, Nakaseomyces glabrata (formerly Candida glabrata) caused 14% of cases of candidaemia in South Africa. We aimed to describe the clinical characteristics of adults with N. glabrata candidaemia at 20 sentinel hospitals (accounting for 20% (172/917) of cases) and the antifungal susceptibility of the corresponding isolates. A higher proportion of patients with N. glabrata candidaemia were older (median age: 55 years [interquartile range (IQR): 41-65 years] vs. 49 years [IQR: 35-63 years]; p = 0.04), female (87/164, 53% vs. 283/671, 42%; p = 0.01), admitted to a public-sector hospital (152/172, 88% vs. 470/745, 63%; p < 0.001), treated with fluconazole only (most with suboptimal doses) (51/95, 54% vs. 139/361, 39%; p < 0.001), and had surgery (47/172, 27% vs. 123/745, 17%; p = 0.001) and a shorter hospital stay (median 7 days [IQR: 2-20 days] vs. 13 days [IQR: 4-27 days]; p < 0.001) compared to patients with other causes of candidaemia. Eight N. glabrata isolates (6%, 8/131) had minimum inhibitory concentrations in the intermediate or resistant range for ≥ 1 echinocandin and a R1377K amino acid substitution encoded by the hotspot 2 region of the FKS2 gene. Only 11 isolates (8%, 11/131) were resistant to fluconazole. Patients with confirmed N. glabrata candidaemia are recommended to be treated with an echinocandin (or polyene), thus further guideline training is required.

Nakaseomyces (formerly Candida) glabrata is a yeast-like fungus that forms part of the commensal gut flora and among people with certain risk factors, can invade into the bloodstream. Nakaseomyces glabrata is a relatively more common cause of candidaemia in high-income vs. low- and middle-income countries. There are no N. glabrata clinical isolates that are considered susceptible to fluconazole, and thus echinocandins are recommended for treatment. However, echinocandin resistance is emerging. We described the characteristics of South African patients with N. glabrata bloodstream infections and the antifungal susceptibility of corresponding isolates. We found that patients infected with N. glabrata were more likely to be older, female, admitted to public hospitals and to be post-surgery and these patients were also more likely to be treated with fluconazole monotherapy and to have stayed a shorter time in hospital compared to patients infected with other Candida species. Only 6% of N. glabrata isolates were echinocandin-resistant with mutations in specific resistance genes that we have found in South African N. glabrata isolates previously. Eight percent of N. glabrata isolates were resistant to fluconazole and the remainder were in the susceptible dose dependent category, requiring higher fluconazole treatment doses. Patients with confirmed N. glabrata bloodstream infection should ideally be treated with an echinocandin or polyene rather than fluconazole and training is required for doctors treating these patients.

Time-to-positivity in bloodstream infection for Candida species as a prognostic marker for mortality.

Time-to-positivity (TTP) may assist in predicting the outcome of candidaemia. We analysed a candidaemia dataset collected prospectively in Australia over 1 year (2014-2015). TTP was defined as the period from blood culture sampling to the blood culture flagging positive. Of 415 candidaemia episodes, overall, 30-day mortality was 29% (120/415); mortality with Candida albicans was 35% (59/169), C. glabrata complex, 37% (43/115), C. tropicalis, 43% (10/23), Pichia kudriavzevii 25% (3/12), and C. parapsilosis complex 7% (5/71). Each day of increased TTP multiplied the odds ratio (OR) of survival at 30 days by a factor of 1.32 [95% confidence interval (CI) 1.06-1.69]. Shorter TTP was associated with increased mortality, with 1-day TTP associated with 30-day mortality 37% (41/112) (95%CI: 28%-46%) and 5-day TTP 11% (2/18) (95%CI: 2%-36%).

Time-to-positivity is a measure that is available to clinicians when patients are identified as having candida in their bloodstream. Our data support the association of a shorter time to positivity with higher mortality.

Candida bloodstream infection among children hospitalised in three public-sector hospitals in the Metro West region of Cape Town, South Africa.

BACKGROUND: Candida bloodstream infection (BSI) causes appreciable mortality in neonates and children. There are few studies describing the epidemiology of Candida BSI in children living in sub-Saharan Africa. METHODS: A retrospective descriptive study was conducted at three public sector hospitals in Cape Town, South Africa. Demographic and clinical details, antifungal management and patient outcome data were obtained by medical record review. Candida species distribution and antifungal susceptibility testing results were obtained from the National Health Laboratory Service database. RESULTS: Of the 97 Candida BSI episodes identified during a five-year period, 48/97 (49%) were Candida albicans (C. albicans), and 49/97 (51%) were non-C. albicans species. The overall incidence risk was 0.8 Candida BSI episodes per 1000 admissions at Red Cross War Memorial Children's Hospital. Of the 77/97 (79%) Candida BSI episodes with available clinical information, the median age (interquartile range) at the time of BSI was 7 (1-25) months, 36/77 (47%) were associated with moderate or severe underweight-for-age and vasopressor therapy was administered to 22/77 (29%) study participants. Most of the Candida BSI episodes were healthcare-associated infections, 63/77 (82%). Fluconazole resistance was documented among 17%, 0% and 0% of C. parapsilosis, C. tropicalis and C. albicans isolates, respectively. All Candida isolates tested were susceptible to amphotericin B and the echinocandins. The mortality rate within 30 days of Candida BSI diagnosis was 13/75 (17%). On multivariable analysis, factors associated with mortality within 30 days of Candida BSI diagnosis included vasopressor therapy requirement during Candida BSI, adjusted Odds ratio (aOR) 53 (95% confidence interval 2-1029); hepatic dysfunction, aOR 13 (95% CI 1-146); and concomitant bacterial BSI, aOR 10 (95% CI 2-60). CONCLUSION: The study adds to the limited number of studies describing paediatric Candida BSI in sub-Saharan Africa. Non-C. Albicans BSI episodes occurred more frequently than C. albicans episodes, and vasopressor therapy requirement, hepatic dysfunction and concomitant bacterial BSI were associated with an increase in 30-day mortality.

Effect of the implementation of clinical guidelines on management of candidemia in elderly patients.

INTRODUCTION: Mortality from candidemia is higher in elderly population than in younger patients, which may be related to suboptimal management. The aim of the present study is to evaluate adherence to the recommendations for the clinical management of candidemia in a population over 75 years before and after implementing specific training. PATIENTS AND METHODS: We recorded retrospectively data from candidemia episodes in elderly patients during two periods of time: 2010-2015 years (before training) and 2017-2022 years (after training), as well as adherence to the recommendations of the clinical practice guidelines, mortality and consultation to infectious disease specialists. RESULTS: Forty-five episodes of candidemia were recorded in the first period and 29 episodes in the second period. A better compliance to the recommendations of the clinical practice guidelines was observed in the second period: echocardiogram performance (75.9% vs. 48.9% p = .021), fundoscopy (65.5% vs. 44.4% p = .076), follow-up blood cultures (72.4% vs. 42.2% p = .011), removal of central venous catheter (80% vs. 52.9% p = .080) and adequate antifungal treatment (82.6% vs. 52.6% p = .018). A trend towards lower mortality was observed during the second period (27.6% vs. 44.4% p = .144). CONCLUSION: The improvement of knowledge of clinical guidelines on candidemia and the participation of infectious disease specialists may increase the quality of care in elderly patients with candidemia. It would be necessary to enlarge the sample size to evaluate the real impact of this intervention on mortality.

Candida auris Infection in a Meningococcal Septicemia Survivor, Poland.

BACKGROUND: Candida auris is an emerging pathogen that constitutes a serious global health threat. It is difficult to identify without specific approaches, and it can be misidentified with standard laboratory methods, what may lead to inappropriate management. CASE PRESENTATION: We report, probably the first in Poland, C. auris isolation from blood cultures and wound swabs of a young male following meningococcal septicaemia, in February 2019. The patient had been previously hospitalized in the United Arab Emirates. The isolate was rapidly identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry and therefore clinicians were promptly informed on the alert pathogen isolation. The targeted antifungal treatment was successful and infection control measures seemed effective. ITS-based identification and subsequent whole genome sequencing showed that the C. auris isolate belongs to South Asian lineage (clade I). CONCLUSIONS: C. auris is able to cause outbreaks in healthcare settings. Therefore, it is important to quickly identify C. auris isolates in hospital settings so that healthcare facilities can take proper precautions to limit its spread.

EQUAL Candida score, an effective tool for predicting the outcomes of Candida tropicalis candidaemia: A retrospective cohort study.

BACKGROUND: Candida tropicalis is the most common non-albicans Candida species found in Asia-Pacific countries, including Thailand. The pathogen is known for its great virulence, which causes a high case-fatality rate. Associations between case fatality and patient characteristics, infectious disease unit consultation and EQUAL Candida score were investigated. METHODS: This retrospective cohort study was conducted with 160 cases of C. tropicalis bloodstream infection between 2015 and 2019 at a single, large, tertiary centre in Thailand. Clinical characteristics, clinical presentations, patient outcomes (30-day case-fatality rate) and independent predictive factors were analysed. RESULTS: The 30-day case-fatality rate was 68.1%. The median of the EQUAL Candida score was 8. Independent factors for the prediction of case fatality were septic shock (hazard ratio, 1.84), the use of mechanical ventilation (hazard ratio, 2.03) and the EQUAL Candida score (hazard ratio, 0.75). CONCLUSIONS: The predictive factors for 30-day case fatality were septic shock, mechanical ventilation use and the EQUAL Candida score. It is recommended that the EQUAL score be considered for patients infected with C. tropicalis candidaemia to reduce the case-fatality rate.

South Asian (Clade I) Candida auris meningitis in a paediatric patient in Iran with a review of the literature.

Candida meningitis is a rare life-threatening yeast infection mostly involving immunocompromised or paediatric patients undergoing neurosurgical procedures or shunt placement. Due to difficulties in diagnosis because of diverse clinical manifestations, the number of patients affected is most likely underestimated. Therefore, the correct diagnosis may be delayed for months, and accurate species identification is highly recommended for administering appropriate antifungal therapy. We report the first case of fluconazole-resistant Candida auris meningitis in a paediatric patient in Iran. This strain was probably imported, as it genotypically belonged to Clade I from South Asia. Furthermore, we include a literature review of C auris meningitis cases, as the number of cases with C auris meningitis has increased with reports from the United Kingdom, India and Iran. This problem might increase further in the era of COVID-19 due to attrition of experienced healthcare personnel and a high workload of hospital healthcare workers. To understand the precise prevalence of this emerging multidrug resistance pathogen, epidemiological surveillance studies are urgently warranted.

Performance of existing clinical scores and laboratory tests for the diagnosis of invasive candidiasis in critically ill, nonneutropenic, adult patients: A systematic review with qualitative evidence synthesis.

BACKGROUND: The Fungal Infections Definitions in Intensive Care Unit (ICU) patients (FUNDICU) project aims to provide standard sets of definitions for invasive fungal diseases in critically ill, adult patients. OBJECTIVES: To summarise the available evidence on the diagnostic performance of clinical scores and laboratory tests for invasive candidiasis (IC) in nonneutropenic, adult critically ill patients. METHODS: A systematic review was performed to evaluate studies assessing the diagnostic performance for IC of clinical scores and/or laboratory tests vs. a reference standard or a reference definition in critically ill, nonneutropenic, adult patients in ICU. RESULTS: Clinical scores, despite the heterogeneity of study populations and IC prevalences, constantly showed a high negative predictive value (NPV) and a low positive predictive value (PPV) for the diagnosis of IC in the target population. Fungal antigen-based biomarkers (with most studies assessing serum beta-D-glucan) retained a high NPV similar to that of clinical scores, with a higher PPV, although the latter showed important heterogeneity across studies, possibly reflecting the targeted or untargeted use of these tests in patients with a consistent clinical picture and risk factors for IC. CONCLUSIONS: Both clinical scores and laboratory tests showed high NPV for the diagnosis of IC in nonneutropenic critically ill patients. The PPV of laboratory tests varies significantly according to the baseline patients' risk of IC. This qualitative synthesis will provide the FUNDICU panel with baseline evidence to be considered during the development of definitions of IC in critically ill, nonneutropenic adult patients in ICU.

Antifungal lock therapy: an eternal promise or an effective alternative therapeutic approach?

Each year, millions of central venous catheter insertions are performed in intensive care units worldwide. The usage of these indwelling devices is associated with a high risk of bacterial and fungal colonization, leading to the development of microbial consortia, namely biofilms. These sessile structures provide fungal cells with resistance to the majority of antifungals, environmental stress and host immune responses. Based on different guidelines, colonized/infected catheters should be removed and changed immediately in the case of Candida-related central line infections. However, catheter replacement is not feasible for all patient populations. An alternative therapeutic approach may be antifungal lock therapy, which has received high interest, especially in the last decade. This review summarizes the published Candida-related in vitro, in vivo data and case studies in terms of antifungal lock therapy. The number of clinical studies remains limited and further studies are needed for safe implementation of the antifungal lock therapy into clinical practice.

Comparisons of the clinical and mycological characteristics of pediatric candidemia.

BACKGROUND/PURPOSE: Invasive candidiasis is a severe infectious disease that could lead to mortality in critically ill children. METHODS: We collected data regarding demographics, underlying diseases, predisposing factors, outcomes for pediatric patients with candidemia at a medical centre in Taiwan from 2011 to 2017. RESULTS: Fifty-eight patients with 60 candidemia episodes were diagnosed. The 3 most common species were Candida albicans (42%), Candida parapsilosis (25%) and Candida tropicalis (23%). C. parapsilosis predominantly infected infants and neonates (median age: 0.8 years, range: 0.1-14.5). Cases with C. tropicalis had significantly higher rates of multidrug resistance (p = 0.011) and disseminated candidiasis (p = 0.025) compared with other cases. The all-cause mortality rate was 43%, and the candidemia-related mortality rate was 29%. Pediatric sequential organ failure assessment score >8 [adjusted odds ratio (aOR) 66.2, 95% CI 4.03-1088.5] and posaconazole resistance (aOR 33.57, 95% CI 1.61-700.3) were the most significant risk factors associated with candidemia-related mortality, whereas treatment with effective antifungal agents within 48 h (aOR 0.07, 95% CI 0.01-0.9) was the only significant protective factor. CONCLUSION: Candidemia-related mortality was related to azole resistance; therefore, empirical therapy with echinocandin or amphotericin B is recommended pending species and susceptibility results.

Consensus guidelines for the diagnosis and management of invasive candidiasis in haematology, oncology and intensive care settings, 2021.

Patients with haematological malignancies, haemopoietic stem cell transplant recipients and patients requiring admission to intensive care settings are at high risk for invasive candidiasis (IC). Over the past decade, there has been increased reporting of non-albicans species and fluconazole resistance in Australia. These guidelines provide updated evidence-based recommendations for the diagnosis and management of IC in adult and paediatric haematology, oncology and intensive care settings. Optimal pharmacological and non-pharmacological management are discussed. Recent studies strengthen the recommendation for an echinocandin agent as first-line therapy for high-risk patients with IC. Mortality benefit has also been demonstrated for non-pharmacological management, including removal of central venous catheters, infectious diseases consultation and use of care bundles. Healthcare facilities managing immunocompromised patient populations should therefore adopt implementation strategies for these multimodal interventions.

Serious fungal disease incidence and prevalence in Indonesia.

BACKGROUND: Indonesia is a tropical country, warm and humid, with numerous environmental fungi. Data on fungal disease burden help policymakers and clinicians. OBJECTIVES: We have estimated the incidence and prevalence of serious fungal diseases. METHODS: We found all published and unpublished data and estimated the incidence and prevalence of fungal diseases based on populations at risk. HIV data were derived from UNAIDS (2017), pulmonary tuberculosis (PTB) data from 2013-2019, data on chronic pulmonary aspergillosis (CPA) were used to estimate CPA prevalence and likely deaths, COPD data from Hammond (2020), lung cancer incidence was from Globocan 2018, and fungal rhinosinusitis was estimated using community data from India. RESULTS: Overall ~7.7 million Indonesians (2.89%) have a serious fungal infection each year. The annual incidence of cryptococcosis in AIDS was 7,540. Pneumocystis pneumonia incidence was estimated at 15,400 in HIV and an equal number in non-HIV patients. An estimated 1% and 0.2% of new AIDS patients have disseminated histoplasmosis or Talaromyces marneffei infection. The incidence of candidaemia is 26,710. The annual incidence of invasive aspergillosis was estimated at 49,500 and the prevalence of CPA is at 378,700 cases. Allergic bronchopulmonary aspergillosis prevalence in adults is estimated at 336,200, severe asthma with fungal sensitisation at 443,800, and fungal rhinosinusitis at 294,000. Recurrent vulvovaginal candidiasis is estimated at 5 million/year (15-50 years old). The incidence of fungal keratitis around 40,050. Tinea capitis prevalence in schoolchildren about 729,000. CONCLUSIONS: Indonesia has a high burden of fungal infections.

Candidaemia in Central Slovenia: A 12-year retrospective survey.

BACKGROUND: Candida bloodstream infections (BSI) became an important invasive disease in the late 20th century, in particular among immunocompromised patients. Although considerable progress has been made in the management of patients with invasive mycoses, Candida BSI are still widespread among hospitalised patients and are associated with relatively high mortality. OBJECTIVES: We conducted a retrospective study to evaluate patient characteristics, incidence, species distribution and antifungal susceptibility of BSI isolates of Candida spp. as well as outcomes of Candida BSI from 2001 to 2012, before the widespread use of echinocandins. This is the first epidemiological study of Candida BSI in Slovenia so far. METHODS: All documented candidaemia cases from 2001 to 2012 in two major hospitals-University Medical Centre and Institute of Oncology in Ljubljana, Slovenia-were taken into consideration. Candida BSI were identified in 422 patients (250 male, 172 female). Laboratory and clinical data of these patients were retrospectively analysed. Mann-Whitney U test was used to compare continuous variables and Fisher's exact test or chi-squared test for categorical variables. RESULTS AND CONCLUSIONS: The average incidence of Candida BSI was 0.524/10.000 patient-days (0,317/1000 admissions); 16/422 were younger than 1 year and 251/422 patients were over 60 years old. The most commonly isolated species were Candida albicans and Candida glabrata, followed by Candida parapsilosis. Majority of the patients had a single episode of Candida BSI, multiple episodes of Candida BSI occurred in 18/434 patients (4.1%); in 25/434 patients (5.8%) mixed Candida BSI were observed. Crude 30-day case-fatality rate was 55.4%.

A retrospective validation of different scores of guideline adherence and infectious diseases consultation on candidaemia: The higher, the better.

BACKGROUND: Recently, several scores to quantify compliance with the guidelines in candidaemia management (EQUAL, GEMICOMED, Valerio) have been developed. Evidence supporting the association of these scores to the prognosis is scarce. We aim to evaluate the performance of these candidaemia guideline adherence scores to predict candidaemia outcome. METHODS: We recorded retrospectively data from candidaemia episodes (January 2017-December 2018). We analysed adherence to guidelines for candidaemia management according to EQUAL, GEMICOMED and Valerio scores, and we correlated those to outcome. RESULTS: Fifty-four first episodes of candidaemia were retrieved. Five patients who died in the first 48 hours after blood cultures were not included. Thirty-day mortality in evaluable patients was 18.4%. Median adherence to guidelines according to EQUAL score was 17 (interquartile range [IQR]: 15-19), and according to GEMICOMED was 86% (IQR: 72.5%-100%). According to Valerio score, adequacy of antifungal prescription was 8.5/10 (SD: 1.9). A cut-off of ≥17 for EQUAL or compliance >70% for GEMICOMED was associated with inferior 30-day mortality (7.1% vs 33.3%, P = .028 and 7.9% vs 54.5%, P = .002, respectively). Infectious diseases (ID) evaluated cases obtained a better EQUAL score (>17; 82.1% vs 42.9%, P = .006), had inferior 30-day mortality (9.4% vs 35.3%, P = .049) and a better antifungal prescription adequacy (Valerio score 9.0 vs 7.5, P = .011). CONCLUSION: Adherence to guidelines for candidaemia management evaluated by means of EQUAL and GEMICOMED score was associated with a decreased 30-day mortality. Adequacy of antifungal prescription can be ameliorated. ID consultation improved guideline adherence and was associated with decreased 30-day mortality.

Modified Pitt bacteremia score for predicting mortality in patients with candidaemia: A multicentre seven-year retrospective study conducted in Japan.

BACKGROUND: Several severity indexes have been reported for critically ill patients. The Pitt bacteremia score (PBS) is commonly used to predict the risk of mortality in patients with bacteraemia. OBJECTIVES: To develop a scoring system for predicting mortality in candidaemia patients. METHODS: Medical records at five Japanese tertiary hospitals were reviewed. Factors associated with mortality were analysed using logistic regression modelling. The discriminatory power of scoring models was evaluated by assessing the area under the receiver operating characteristic curve (AUC), net reclassification improvement (NRI) and integrated discrimination improvement (IDI). RESULTS: In total, 422 candidaemia patients were included. Higher PBS, dialysis and retainment of central venous catheter were independent risk factors for all-cause 30-day mortality. However, among the five PBS components, fever was not associated with mortality; therefore, we developed a modified version of the PBS (mPBS) by replacing fever with dialysis. AUC for PBS and mPBS were 0.74 (95% confidence interval [CI]: 0.68-0.80) and 0.76 (95% CI: 0.71-0.82), respectively. The increase in predictive ability of mPBS for 30-day mortality was statistically significant as assessed by NRI (0.24, 95% CI: 0.01-0.46, p = .04) and IRI (0.04, 95% CI: 0.02-0.06, p = .0008). When patients were stratified by mPBS into low (scores 0-3), moderate (4-7) and high risk (≥8), there were significant differences among the survival curves (p < .0001, log-rank test), and 30-day mortality rates were 13.8% (40/290), 36.8% (28/76) and 69.4% (34/49), respectively. CONCLUSIONS: mPBS can be a useful tool for predicting mortality in candidaemia patients.
