Distribution and epidemiology of Candida species causing fungemia at a Saudi Arabian hospital, 1996-2004

Clinical and Microbiological Characteristics of Candidemia Cases in Saudi Arabia

Purpose

Candidemia and antifungal resistance are major healthcare challenges. The aim of this study is to describe the frequency of candidemia cases, distribution of Candida spp., and the associated risk factors for mortality in an academic institution in Saudi Arabia over an 18-month period. We also evaluated the susceptibility patterns of Candida blood isolates.

Methods

Candidemia cases were collected from King Fahad Hospital of the University over the period between July 1st, 2020 through December 31st, 2021. They were prospectively reviewed for the preceding risk factors and antifungal (AF) susceptibility, testing results to fluconazole (FL), voriconazole (VO), itraconazole (IT), posaconazole (PO), caspofungin (CASP), anidulafungin (AND), micafungin (MYC), flucytosine (FLC) and amphotericin B (AMPB) using a broth microdilution kit (Sensititre™ YeastOne).

Results

A total of 48 candidemia isolates were included that were isolated from 43 patients. The median age of cases was 62 ± 23.3 years (60.4% males and 83% ICU patients). Independent risk factors for mortality at 30 days in candidemia patients were age, COVID-19 co-infection, and use of tocilizumab. The most commonly isolated species were C. glabrata and C. parapsilosis (22.9% each) followed by C. albicans (18.75%). AF resistance for ≥1 antifungal was detected in 39.3% of 33 cases tested, with no cross-resistance identified. Resistance rates for each AF were as follows: FL (18%), VO (6%), IT (6%), PO (9%) and AMPB (3%). No resistance was seen for echinocandins apart from one C. krusei strain showing an intermediate result for CASP.

Conclusion

The study showed an overall high rate of non-albicans Candida, with the predominance of C. parapsilosis and C. glabrata, representing a therapeutic challenge. AF resistance rate was high which emphasizes the importance of continuing surveillance and providing accurate and reliable tools in the laboratories for rapid speciation and susceptibility testing.

Increased prevalence of fungemia in Medina, Saudi Arabia

Background

The prevalence of fungal infection is increasing globally due to an increase in the immunocompromised and aging population. We investigated epidemiological changes in fungemia in one of the major centers in Medina over seven years period with 87,447 admissions.

Methods

Retrospective search of records for causative agents of fungemia in inpatients at King Fahad Hospital (KFH) in 2013-2019. Fungal-positive blood cultures, demographic, and treatment data were extracted.

Results

A total of 331 fungemia episodes proven by blood culture were identified in 46 patients. The annual prevalence of fungemia increased from 0.072 in 2013 to 1.546 patients per 1,000 in 2019. The mean age of fungemia episodes was 56 years, and 62% of episodes occurred in females. Samples from central blood incubated aerobically yielded the highest fungemia rate, accounting for 55% (n = 182). Among yeast species, Candida parapsilosis was responsible for the highest number of episodes 37% (n = 122), followed by Candida glabrata (32%; n = 107), Candid albicans (29%; n = 94), and Cryptococcus neoformans (1%; n = 4). Among molds, Lichtheimia (Absidia) species was the most common (1%; n = 3). Yeast-like fungi Trichosporion mucoides accounted for (0.003% n = 1). The use of antifungal treatment has increased (96%) over the years (2013-2019). An increase in resistance rate of 2% was found in C. albicans and C. glabrata. The most prevalent comorbidity was renal disease (24.2%).

Conclusions

C. parapsilosis was the leading cause of fungemia. The association of renal disease with increased candidemia was alarming. This study is a fundamental resource to establish management policies for fungal infection in the region.

Clinical characteristics and outcome of candidemia: Experience from a tertiary referral center in Saudi Arabia

Background:

Candida bloodstream infections cause significant excess morbidity and mortality in the health-care setting. There is limited evidence regarding Candida species causing invasive infections in Saudi Arabia.

Objective:

To identify Candida species causing bloodstream infection and determine the clinical outcome and factors associated with mortality in a tertiary center in Saudi Arabia.

Materials and Methods:

This retrospective study included all cases of positive blood culture for Candida in patients admitted to King Abdulaziz Medical City, a tertiary care center in Riyadh, Saudi Arabia, between January 1, 2013 and June 30, 2019.

Results:

A total of 532 patients with candidemia were identified (male: 55.4%; mean age: 54 ± 26.2 years). The most common Candida species isolated was Candida albicans (26.7%), followed by Candida glabrata (22.7%), Candida parapsilosis (22.2%), and Candida tropicalis (18.4%). Non-albicans candidemia was more common in patients with diabetes (76.7%; P = 0.0560), neutropenia (89.8%; P = 0.0062), recent exposure to fluconazole (85.7%; P = 0.0394), and active chemotherapy (83.1%; P = 0.0128). In non-albicans, susceptibility to fluconazole varied from 95.9% with C. tropicalis to 41.5% with C. parapsilosis; nonetheless, all species were highly susceptible to echinocandins. The overall 30- and 90-day mortality rates were 39.9% and 56.4%, respectively. The mortality rate was nonsignificantly higher with non-albicans species at 30 days (41.2% vs. 35.9%; P = 0.2634) and 90 days (58.2% vs. 51.4%; P = 0.1620).

Conclusion:

This study found a changing pattern in the Candida species causing bloodstream infections and an epidemiological shift toward more non-albicans Candida species in Saudi Arabia.

Novel Antifungal Activity of Q-Griffithsin, a Broad-Spectrum Antiviral Lectin

There is a rising global incidence of Candida strains with high levels of resistance to fluconazole and other antifungal drugs, hence the need for novel antifungal treatment strategies. Here, we describe the first evidence of antifungal activity of Q-Griffithsin (Q-GRFT), a recombinant oxidation-resistant variant of Griffithsin, a marine red algal lectin with broad-spectrum antiviral activity. We demonstrated that Q-GRFT binds to α-mannan in the Candida albicans cell wall. We also observed that Q-GRFT binding disrupted cell wall integrity and induced reactive oxidative species (ROS) formation, resulting in cell death. Furthermore, we showed that Q-GRFT inhibited the growth of other Candida species C. glabrata, C. parapsilosis, and C. krusei and had modest activity against some strains of multi- and pandrug-resistant C. auris. We found that Q-GRFT induced differential expression of numerous genes involved in response to cell stress, including those responsible for neutralizing ROS production and cell cycle regulation. In conclusion, this novel antifungal activity suggests that Q-GRFT is potentially an ideal drug candidate and represents an alternative strategy for the prevention and treatment of candidiasis. IMPORTANCE Fungal infections contribute to morbidity and mortality annually, and the number of organisms that are nonresponsive to the current available drug regimens are on the rise. There is a need to develop new agents to counter these infections and to add to the limited arsenal available to treat fungal infections. Our study has identified Q-GRFT, a broad-spectrum antiviral protein that harbors growth-inhibitory activity against several Candida strains, as a potential candidate for the prevention and treatment of fungal infections.

Predominance of Candida Glabrata among Non-albicans Candida Species in a 16-Year Study of Candidemia at a Tertiary Care Center in Lebanon

Background: Candidemia is associated with a high mortality rate, and its incidence is increasing worldwide with a rise in non-albicans candidemia (NAC). Epidemiologic data from Arab countries are scarce and there are no data from Lebanon; Methods: This is a single-center retrospective chart review of patients with candidemia in a tertiary care center in Lebanon from 2004 to 2019. We extracted data on patient characteristics, isolated Candida species antifungal susceptibility, management and outcomes; Results: We included 170 cases of candidemia. NAC was more common than albicans candidemia (64.7% vs. 35.3%). C. glabrata was the most common non-albicans species (37 isolates) followed by C. tropicalis (14). Recent use of antifungals was a risk factor for NAC (OR = 2.8, p = 0.01), while the presence of a central venous catheter was protective (OR = 0.41, p = 0.02). Fluconazole resistance was 12.5% in C. albicans and 21.5% in non-albicans spp. Mortality at 30 days was 55.5%, with no difference between NAC and albicans candidemia. It was higher in older and critically ill patients but lower in patients whose central venous catheter was removed after detecting fungemia; Conclusions: Candidemia is associated with high mortality in Lebanon, with a predominance of NAC and high prevalence of C. glabrata.

A seven-year surveillance of Candida bloodstream infection at a university hospital in KSA

Objectives

Candidemia incidence has increased in the past few years, with high mortality. Previous studies have reported a variable distribution of Candida spp. among different regions. This study aimed to identify the species found in Candida bloodstream infections, routine antifungal susceptibility testing, and mortality outcomes in an academic medical centre.

Methods

Between January 2012 and December 2018, the positive blood cultures for candidemia infection were retrieved and statistically analysed for species prevalence, susceptibility pattern, and crude mortality at 14, 30, 60 and 90 days.

Results

Of 156 candidemia cases, a majority (69.2%) was caused by non-albicans Candida spp. After Candida albicans (30.8%), Candida tropicalis and Candida parapsilosis were the second and third most frequeunt isolates spp, each counting for 23.7%. Acquired resistance was detected in 14.8% of candidemia strains. No other antifungal resistance was detected. The overall crude mortality rates of all species were 29.3%, 47.9%, 56.4%, and 58.0% at 14, 30, 60, and 90 days, respectively. A higher mortality rate was noted in cases of Candida krusei infection (crude mortality 71.4–100%, p = 0.002).

Conclusion

In this study, a considerable shift to non-albicans Candida causing most bloodstream infections was observed. As such infections pose a serious threat to hospitalised patients, microbiology laboratories are urged to adopt rapid diagnostic and minimal inhibitory concentration-based testing for the detection of susceptible dose-dependent phenotypes. Prospective studies are essential to consider the prognosis of bloodstream infections by various Candida species in a multivariate model.

Antifungal resistance in patients with Candidaemia: a retrospective cohort study

Background

Candidaemia is the most common form of invasive candidiasis. Resistant Candida blood stream infection (BSI) is rising, with limitations on the development of broader-spectrum antifungal agents worldwide. Our study aimed to identify the occurrence of antifungal-resistant candidaemia and the distribution of these species, determine the risk factors associated with antifungal resistance and evaluate the association of antifungal-resistant candidaemia with the length of intensive care unit (ICU) and hospital stay and with 30-day mortality.

Methods

A retrospective cohort study was conducted at King Faisal Specialist Hospital and Research Centre, Jeddah, Saudi Arabia. Adult patients diagnosed with candidaemia from January 2006 to December 2017 were included.

Results

A total of 196 BSIs were identified in 94 males (49.74%) and 95 females (50.26%). C. glabrata was the most commonly isolated Candida species, with 59 (30%), followed by C. albicans with 46 (23%). Susceptibility data were available for 122/189 patients, of whom 26/122 (21%) were resistant to one or more antifungals. C. parapsilosis with available sensitivity data were found in 30/122 isolates, of which 10/30 (33%) were resistant to fluconazole. Risk factors significantly associated with antifungal-resistant candidaemia included previous echinocandin exposure (odds ratio (OR) =1.38; 95% confidence interval (CI) (1.02–1.85); P = 0.006) and invasive ventilation (OR = 1.3; 95% CI (1.08–1.57); P = 0.005). The median length of ICU stay was 29 days [range 12–49 days] in the antifungal-resistant group and 18 days [range 6.7–37.5 days] in the antifungal-sensitive group (P = 0.28). The median length of hospital stay was 51 days [range 21–138 days] in the antifungal-resistant group and 35 days [range 17–77 days] in the antifungal-sensitive group (P = 0.09). Thirty-day mortality was 15 (57.7%) and 54 (56.25%) among the antifungal-resistant and antifungal-sensitive groups, respectively (OR = 1.01; 95% CI (0.84–1.21); P = 0.89).

Conclusions

Our results indicate a high frequancy of non- C. albicans candidaemia. The rise in C. parapsilosis resistance to fluconazole is alarming. Further studies are required to confirm this finding.

Candida Bloodstream Infection: Changing Pattern of Occurrence and Antifungal Susceptibility over 10 Years in a Tertiary Care Saudi Hospital

Background

Candida has emerged as one of the most important pathogens that cause bloodstream infection (BSI).Understanding the current Candida BSI trends, the dominant species causing disease and the mortality associated with this infection are crucial to optimize therapeutic and prophylaxis measures.

Objectives

To study the epidemiology and to evaluate the risk factors, prognostic factors, and mortality associated with candidemia and to compare these findings with previously published studies from Saudi Arabia.

Design

A retrospective medical record review.

Setting

Tertiary hospital in Riyadh.

Patients and Methods

The analysis included all cases of Candida blood stream infection who are >18 years old over the period from 2013 to 2018. Continuous variables were compared using the parametric T-test while categorical variables were compared using the Chi-squared test.

Main Outcome Measure

Incidence, resistance, and hospital outcomes in Candida blood stream infection.

Sample Size

324 patients.

Results

Three hundred and twenty-four episodes of Candida blood stream infections were identified. Median age of patients was 49.7 SD ± 28.1 years, and 53% of patients were males. More than half of the patients had an underlying disease involving the abdomen or laparotomy, 78% had an indwelling intravenous catheter, and 62% had suffered a bacterial infection within 2 weeks prior to candidemia. Candida albicans represents 33% of all isolates with decreasing trend overtime. There was an increase in the number of nonalbicans Candida overtime with Candida tropicalis in the lead (20%). Use of broad spectrum antibiotics (82%), prior ICU admission (60%) and use of central venous catheters (58%) were the most prevalent predisposing factors of candidemia. Azole resistance was variable overtime. Resistance to caspofungin remained very low (1.9%). Fourteen days crude mortality was 37% for ICU patients and 26.7% in non-ICU patients, while hospital crude mortality was 64.4% and 46.7%, respectively.

Conclusion

There is an increasing trend of nonalbicans Candida blood stream infection. Fluconazole resistance remained low to C. albicans. Most isolates remain susceptible to caspofungin, voriconazole, and amphotericin B. Candida bloodstream infection is associated with high 14-day hospital mortality.

Epidemiology and burden of invasive fungal infections in the countries of the Arab League

The burden of invasive fungal infections is alarming worldwide. The aim of this paper is to review the published literature and evaluate the knowledge gap pertaining to studies on invasive fungal infections in the countries of the Arab League. Few countries from this region have published reports. The most commonly studied invasive fungal infections is invasive candidiasis. Candida albicans remains overall the most common causative pathogen (33.8-60%), however, non-albicans Candida species are increasing. Antifungal susceptibility testing is non-standardized across the published studies. Data on aspergillosis and other fungal infections is scarce. This sheds light on the need for standardized surveillance in the region encompassing more countries of the Arab League to guide diagnostic approach and empiric therapy.

Epidemiology and source of infection in patients with febrile neutropenia: A ten-year longitudinal study

OBJECTIVES

No recent studies are available from Saudi Arabia on the etiology of febrile neutropenia. The objective of this study was to describe the characteristics of patients with febrile neutropenia and to calculate the rate of occurrence of bacteremia in these patients.

METHODS

This is a hospital-based study of patients admitted with febrile neutropenia from 2006 to 2015.

RESULTS

A total of 372 distinct episodes of febrile neutropenia representing 231 patients were included. Hematologic malignancies constituted 56.6% of the episodes. Positive blood cultures were reported in 13.5% with equal frequency of Gram-negative bacilli and gram positive cocci. The most commonly suspected sites of infection were blood 10.8% and pulmonary 9.2%, and the majority (72.5%) was thought to have no identifiable source of infection. Of all the episode, 32% had central venous catheters. The most frequently used single antimicrobial agents were imipenem (38%) and ceftazidime (7.5%). The mortality rate was 11.2% and it was significantly associated with the presence of bacteremia 24.4% versus 12.4% (P=0.016). Mortality was not significantly association with age, type of malignancy, presence of central venous catheter, or the severity of neutropenia. Compared to patients with hematological malignancy, patients with solid organ malignancy were more likely to be female 62% versus 14.9% (P<0.001) and were less likely to have bacteremia 8.7% versus 17.1%, P=0.042, respectively.

CONCLUSION

We had shown that febrile neutropenia in this study has a low rate of bacteremia and that about 45% received the recommended initial empiric therapy.

Epidemiologic characteristics of adult candidemic patients in a secondary hospital in Kuwait: A retrospective study

Candida blood steam infection is a life-threatening disease that seems to be under estimated. Understanding epidemiology of such disease is crucial for improved diagnosis, optimized treatment, and better outcome. Through this retrospective study, we aimed to determine the incidence of candidemia in a secondary care hospital, and to describe the epidemiology and outcome of candidemia among adult patients. The incidence of candidemia for all age groups was 0.24, 0.16 and 0.15 cases/1000 patient-days in 2014, 2015 and 2016 respectively. Among adult patients, 82 cases were identified. The patients had the following clinical characteristics with varying proportions: old age, diabetes, antibiotic exposure, use of vascular catheter, abdominal surgery, ICU hospitalization, haemodialysis, and total parenteral nutrition. All-cause 30-day mortality was 54% and ICU hospitalization was a recognized risk factor for death. The leading causative agents were Candida albicans (32%), and Candida parapsilosis (32%), followed by Candida tropicalis (20%), Candida glabrata (13%) and one each by Candida dubliniensis, Candida famata, and Candida auris. Almost all tested isolates were susceptible to caspofungin and amphotericin B. With regard to fluconazole, C. glabrata showed variable susceptibility. Other species were susceptible except one isolate, each of C. parapsilosis and C. auris. The study highlights the growing importance of non-C. albicans Candida species in the etiology of candidemia. Emergence of C. auris is a warning sign and needs to be closely monitored.

Invasive Candidiasis in Critically Ill Patients: A Prospective Cohort Study in Two Tertiary Care Centers

Background:

Invasive candidiasis is not uncommon in critically ill patients but has variable epidemiology and outcomes between intensive care units (ICUs). This study evaluated the epidemiology, characteristics, management, and outcomes of patients with invasive candidiasis at 6 ICUs of 2 tertiary care centers.

Methods:

This was a prospective observational study of all adults admitted to 6 ICUs in 2 different hospitals between August 2012 and May 2016 and diagnosed to have invasive candidiasis by 2 intensivists according to predefined criteria. The epidemiology of isolated Candida and the characteristics, management, and outcomes of affected patients were studied. Multivariable logistic regression analyses were performed to identify the predictors of non-albicans versus albicans infection and hospital mortality.

Results:

Invasive candidiasis was diagnosed in 162 (age 58.4 ± 18.9 years, 52.2% males, 82.1% medical admissions, and admission Acute Physiology and Chronic Health Evaluation II score 24.1 ± 8.4) patients at a rate of 2.6 cases per 100 ICU admissions. On the diagnosis day, the Candida score was 2.4 ± 0.9 in invasive candidiasis compared with 1.6 ± 0.9 in Candida colonization (P < .01). The most frequent species were albicans (38.3%), tropicalis (16.7%), glabrata (16%), and parapsilosis (13.6%). In patients with candidemia, antifungal therapy was started on average 1 hour before knowing the culture result (59.6% of therapy initiated after). Resistance to fluconazole, caspofungin, and amphotericin B occurred in 27.9%, 2.9%, and 3.1%, respectively. The hospital mortality was 58.6% with no difference between albicans and non-albicans infections (61.3% and 54.9%, respectively; P = .44). The independent predictors of mortality were renal replacement therapy after invasive candidiasis diagnosis (odds ratio: 5.42; 95% confidence interval: 2.16-13.56) and invasive candidiasis leading/contributing to ICU admission versus occurring during critical illness (odds ratio: 2.87; 95% confidence interval: 1.22-6.74).

Conclusions:

In critically ill patients with invasive candidiasis, non-albicans was responsible for most cases, and mortality was high (58.6%). Antifungal therapy was initiated after culture results in 60% suggesting low preclinical suspicion. Study registration: NCT01490684; registered in ClinicalTrials.gov on February 11, 2012.

Benchmarking of antibiotic usage: An adjustment to reflect antibiotic stewardship program outcome in a hospital in Saudi Arabia

Antimicrobial stewardship program aims to reduce antibiotic use. Periodic measurement and monitoring of antibiotic use and comparison within the institution as well as with other organizations are important indicators. We analyzed antibiotic usage in a general hospital in Saudi Arabia. Antibiotic data were collected retrospectively for 2011 and from 2013 to 2015, and only adult patients (>15 year of age) were included in the study. Data were presented as days of therapy (DOT) and defined daily dose (DDD). DDD was adjusted per 100 bed-days and according to the case mix index (CMI). The total DDD was 37,557 in 2013, 36,550 in 2014 and 38,738 in 2015. The DDD per 100 patient-days was 90.7–94.5. There was a discordant findings of antibiotic measurements based on the DDD compared to DOT, and DDD/100 bed-days compared to DOT/100 bed-days. There was a negative correlation between CMI and DDD per 100 bed days (r −0.696), but a positive correlation of CMI with DOT (r +0.93). Adjusted DDD/100 bed-days showed decrease in the usage of antibiotics, reflecting activities of the antibiotic stewardship program. The increase in DOT/100 bed-days may indicate the favorable utilization of combination therapy. Antibiotic usage needs to be adjusted per 100 bed-days and correlated with CMI for better reflection of optimal antibiotic utilization, activities of the antibiotic stewardship program, and to allow benchmarking.

Epidemiology and outcome of invasive fungal infections and methicillin-resistant Staphylococcus aureus (MRSA) pneumonia and complicated skin and soft tissue infections (cSSTI) in Lebanon and Saudi Arabia

The objectives of this retrospective medical chart review study were to document the inpatient incidence, treatment, and clinical outcomes associated with invasive fungal infections (IFI) due to Candida and Aspergillus species, Methicillin-resistant Staphylococcus aureus (MRSA) pneumonia and MRSA complicated skin and soft tissue infections (cSSTI) in the Middle East. This study evaluated 2011-2012 data from 5 hospitals in Saudi Arabia and Lebanon with a combined total of 207,498 discharges. Hospital medical chart data were abstracted for a random sample of patients with each infection type (102 patients - IFI, 93 patients - MRSA pneumonia, and 87 patients-MRSA cSSTI). Descriptive analysis found that incidence of IFI (per 1000 hospital discharges) was higher than MRSA cSSTI and MRSA pneumonia (IFI: 1.95 and 2.57; MRSA cSSTI: 2.01 and 0.48; and MRSA pneumonia 0.59 and 0.55 for Saudi Arabia and Lebanon, respectively). Median time from hospital admission to diagnosis and from admission to initiation of active therapy were 6 and 7 days, respectively, in IFI patients; median time from admission to diagnosis was 2days for both MRSA pneumonia and cSSTI, with a median of 4 and 2days from admission to MRSA-active antibiotic start, respectively. The mean hospital LOS was 32.4days for IFI, 32.4days for MRSA pneumonia and 26.3days for MRSA cSSTI. Inpatient mortality was higher for IFI (42%) and MRSA pneumonia (30%) than for MRSA cSSTI (8%). At discharge, 33% of patients with IFI and 27% and 9% of patients with MRSA pneumonia and cSSTI, respectively, were considered to have failed therapy. In conclusion, there is a significant burden of these serious infections in the Middle East, as well as opportunity for hospitals to improve the delivery of patient care for difficult-to-treat infections by promoting expedited diagnosis and initiation of appropriate antimicrobial therapy.

Epidemiological and mycological characteristics of candidemia in Iran: A systematic review and meta-analysis

To date, there has been no comprehensive review of the epidemiology, risk factors, species distribution, and outcomes of candidemia in Iran. This study aimed to perform a systematic review and meta-analysis of all reported candidemia cases in Iran until December 2015. The review process occurred in three steps, namely a literature search, data extraction and statistical analyses. After a comprehensive literature search, we identified 55 cases. The mean age of patients was 46.80±24.30 years (range 1-81 years). The main risk factors for candidemia were surgery and burns (23.6%), followed by malignancies (20%), use of broad-spectrum antibiotics (18.2%), and diabetes (7.3%). Candida parapsilosis (n=17, 30.8%) was the leading agent, followed by Candida albicans (n=15, 27.3%), Candida glabrata (n=10, 18.2%), and Candida tropicalis (n=8, 14.5%). The frequencies of candidemia cases due to C. glabrata, C. parapsilosis, and C. albicans were significantly higher among patients aged>60, 21-40, and 41-60 years, respectively. Comparison of risk factors for candidemia by multiple logistic regression showed that one of the most important risk factors was surgery (OR: 4.245; 95% CI: 1.141-15.789; P=0.031). The outcome was recorded in only 19 cases and 13 of those patients (68.4%) expired. This study confirms that knowledge of the local epidemiology is important when conducting surveillance studies to prevent and control candidemia and will be of interest for antifungal stewardship.

Incidence of <em>Candida</em> species colonization in neonatal intensive care unit at Riyadh Hospital, Saudi Arabia

Background: Candida species are important hospital-acquired pathogens in infants admitted to the neonatal intensive care unit (NICU). This study was performed in the NICU of Saudi Arabian Hospital, Riyadh region, KSA to analyze patterns of neonatal Candida colonization as well as to determine the potential risk factors.Methods: Weekly surveillance fungal cultures of anal area, oral cavity, umbilicus and ear canal of neonates were performed from birth until their discharge from the hospital. Colonization was analyzed for timing, site, species, birth weight and gestational age. Potential environmental reservoirs and hands of health care workers (HCWs) were also cultured monthly for fungi. Antifungal susceptibility of the identified isolates was also determined.Results: One hundred subjects have been recruited in this study. The overall colonization rate was 51%. Early colonization was found in 27 (27%) neonates whereas 24 (24%) neonates were lately colonized during their stay in NICU. Colonization was more in preterm neonates than in full and post term. Perianal area and oral cavity were the most frequent colonized sites. C. albicans was the main spp. (58.8%) isolated from the neonates followed by C. tropicalis (17.6%), C. glabrata (15.6%), and C. krusei (2%). Of the 51 isolated Candida spp., 68.6% were sensitive to fluconazole, 80% to itraconazole and 64.7% to ketoconazole, while only 33% were sensitive to amphotericin B.Conclusion: Candida has emerged as a common cause of infections in infants admitted to NICU, and C. albicans is the most commonly isolated candidal species. Neonatal infections caused by non- albicans species occur at a later age during their stay in NICU.

Central venous catheter (CVC) removal for patients of all ages with candidaemia

BACKGROUND

Candida bloodstream infections most often affect those already suffering serious, potentially life-threatening conditions and often cause significant morbidity and mortality. Most affected persons have a central venous catheter (CVC) in place. The best CVC management in these cases has been widely debated in recent years, while the incidence of candidaemia has markedly increased.

OBJECTIVES

The main purpose of this review is to examine the impact of removing versus retaining a CVC on mortality in adults and children with candidaemia who have a CVC in place.

SEARCH METHODS

We searched the following databases from inception to 3 December 2015: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid SP), EMBASE (Ovid SP), the Commonwealth Agricultural Bureau (CAB), Web of Science and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We searched for missed, unreported and ongoing trials in trial registries and in reference lists of excluded articles.

SELECTION CRITERIA

We searched for randomized controlled trials (RCTs) and quasi-RCTs involving adults and children with candidaemia and in which participants were randomized for removal of a CVC (the intervention under study), irrespective of publication status, date of publication, blinding status, outcomes published or language.However, two major factors make the conduct of RCTs in this population a difficult task: the large sample size required to document the impact of catheter removal in terms of overall mortality; and lack of economic interest from the industry in conducting such a trial.

DATA COLLECTION AND ANALYSIS

Our primary outcome measure was mortality. Several secondary outcome measures such as required time for clearance of blood cultures for Candida species, frequency of persistent candidaemia, complications, duration of mechanical ventilation and length of stay in the intensive care unit (ICU) and in the hospital were planned, as were various subgroup and sensitivity analyses, according to our protocol. We assessed papers and abstracts for eligibility and resolved disagreements by discussion. However, we were not able to include any RCTs or quasi-RCTS in this review and, as a result, have carried out no meta-analyses. However, we have chosen to provide a brief overview of excluded observational studies.

MAIN RESULTS

We found no RCT and thus no available data for evaluation of the primary outcome (mortality) nor secondary outcomes or adverse effects. Therefore, we conducted no statistical analysis.A total of 73 observational studies reported on various clinically relevant outcomes following catheter removal or catheter retention. Most of these excluded, observational studies reported a beneficial effect of catheter removal in patients with candidaemia. None of the observational studies reported results in favour of retaining a catheter. However, the observational studies were very heterogeneous with regards to population, pathogens and interventions. Furthermore, they suffered from confounding by indication and an overall high risk of bias. As a consequence, we are not able to provide recommendations or to draw firm conclusions because of the difficulties involved in interpreting the results of these observational studies (very low quality of evidence, GRADE - Grades of Recommendation, Assessment, Development and Evaluation Working Group).

AUTHORS' CONCLUSIONS

Despite indications from observational studies in favour of early catheter removal, we found no eligible RCTs or quasi-RCTs to support these practices and therefore could draw no firm conclusions. At this stage, RCTs have provided no evidence to support the benefit of early or late catheter removal for survival or other important outcomes among patients with candidaemia; no evidence with regards to assessment of harm or benefit with prompt central venous catheter removal and subsequent re-insertion of new catheters to continue treatment; and no evidence on optimal timing of insertion of a new central venous catheter.

Restrictive reporting of selected antimicrobial susceptibilities influences clinical prescribing

BACKGROUND

Cascade and restrictive reporting are useful strategies to enhance antibiotic stewardship programs.

METHODS

We combined both strategies to improve the prescribing of antibiotics aimed at Gram-negative infections.

RESULTS

For Enterobacter aerogenes, the susceptibility rates to amikacin increased from 10% to 100%; for third generation cephalosporins, these rates increased from 55% to 89%. The susceptibility rates of E. aerogenes to cefepime and piperacillin-tazobactam changed little, and the ampicillin susceptibility decreased from 30% in 2009 to 11% in 2010. For Proteus mirabilis, the susceptibility rates increased for third-generation cephalosporins (48% vs. 92%) and piperacillin-tazobactam (10% vs. 98%), with minimal changes for cefepime (96% vs. 93%), ampicillin (69% vs. 73%) and amikacin (96% vs. 84%). For Pseudomonas aeruginosa, the susceptibility rates improved slightly for third-generation cephalosporins (81% vs. 91%) but reduced for piperacillin-tazobactam (99% vs. 59%). Hospital-acquired Clostridium difficile infections decreased from 0.11 to 0.07 per 1000 patient days.

CONCLUSIONS

Selective reporting helps physicians choose the most appropriate antibiotics for their patients within a stewardship program, with reduced C. difficile infection.

Guideline for diagnosis, prophylaxis and treatment of invasive fungal infection post burn injury in China 2013

Invasive fungal infection is one of the major complication of severe burns which can induce local or systemic inflammatory response and cause serious substantial damage to the patient. The incidence of fungal infection for burn victims is increasing dramatically during recent years. This guideline, organized by Chinese Society of Burn Surgeons, aims to standardize the diagnosis, prevention and treatment of burn invasive fungal infection. It can be used as one of the tools for treatment of major burn patients.

Predictors and outcomes of Candida bloodstream infection: eight-year surveillance, western Saudi Arabia

OBJECTIVES

To assess the epidemiological pattern of Candida bloodstream infection (BSI) over an 8-year period (2002-2009) in King Abdulaziz Medical City, western Saudi Arabia.

METHOD

A retrospective chart review was performed.

RESULTS

A total of 258 BSI were identified in 134 males (53.2%) and 118 females (46.8%). There were 86 (34.1%) cases of Candida albicans and 166 (65.9%) non-albicans Candida species. Malignancy was independently associated with the development of candidemia by non-albicans Candida species (odds ratio 3.24, 95% confidence interval 1.25-8.41). Fluconazole in vitro susceptibility was 38.5% for C. albicans and 52.5% for other Candida species. The overall, crude 12-month mortality rate was 50% for C. albicans and 57.8% for non-albicans Candida species.

CONCLUSIONS

The antifungal resistance coinciding with a change in the epidemiologic pattern of candidemia identified in this study is alarming and urges the need for a review of empiric antifungal therapy and potential contributing environmental factors.

Candida identification: a journey from conventional to molecular methods in medical mycology

The incidence of Candida infections have increased substantially in recent years due to aggressive use of immunosuppressants among patients. Use of broad-spectrum antibiotics and intravascular catheters in the intensive care unit have also attributed with high risks of candidiasis among immunocompromised patients. Among Candida species, C. albicans accounts for the majority of superficial and systemic infections, usually associated with high morbidity and mortality often caused due to increase in antimicrobial resistance and restricted number of antifungal drugs. Therefore, early detection of candidemia and correct identification of Candida species are indispensable pre-requisites for appropriate therapeutic intervention. Since blood culture based methods lack sensitivity, and species-specific identification by conventional method is time-consuming and often leads to misdiagnosis within closely related species, hence, molecular methods may provide alternative for accurate and rapid identification of Candida species. Although, several molecular approaches have been developed for accurate identification of Candida species but the internal transcribed spacer 1 and 2 (ITS1 and ITS2) regions of the rRNA gene are being used extensively in a variety of formats. Of note, ITS sequencing and PCR-RFLP analysis of ITS region seems to be promising as a rapid, easy, and cost-effective method for identification of Candida species. Here, we review a number of existing techniques ranging from conventional to molecular approaches currently in use for the identification of Candida species. Further, advantages and limitations of these methods are also discussed with respect to their discriminatory power, reproducibility, and ease of performance.

The effect of antifungal combination on transcripts of a subset of drug-resistance genes in clinical isolates of Candida species induced biofilms

Biofilm formation is often associated with increased Candida resistance toward antifungal agents. Therefore, the current study aimed to assess the incidence of biofilm formation among Candida isolates and to investigate the effect of high doses of fluconazole {FLC}, voriconazole {VOC} and amphotericin B {AMB}, singly and in combination on mature biofilms. Moreover, it aimed to assess the expression of selected genes (CDR1, KRE1 and SKN1) responsible for Candida biofilm resistance. The study included 49 patients; samples were collected from the King Khalid Hospital, Riyadh, Saudi Arabia. Isolates were prepared for biofilm formation and quantification using 0.4% (w/v) crystal violet. Minimum Inhibitory concentration (MIC) and fractional inhibitory concentration (FIC) were conducted by the broth microdilution method. Biofilm eradication was evaluated using counting, XTT stain intensity and observed under the inverted microscope. Selected genes were evaluated in Candida biofilms under the effect of antifungal exposure using QPCR. The major isolates were Candida albicans (65.3%) followed by Candida tropicalis and Candida glabrata. 77.6% of the strains were biofilm formers. AMB showed susceptibility in 87.8% of isolates, followed by VOC (77.6%) and FLC (67.3%). MIC50 and MIC90 were (0.03, 0.125), (0.5, 8), (2, >128) μg/ml for AMB, VOC and FLC, respectively. 34.7% and 18.4% of the isolates were antagonistic to AMB/FLC and AMB/VOC, respectively. Mature biofilms of ten selected isolates were found resistant to FLC (1000 μg/ml). VOR and AMB concentration required to inhibit biofilm formation was 16-250 fold higher than the MIC for planktonic cells. Isolates showed significant reduction with antifungal combination when compared with the untreated controls (p value ⩽ 0.01), or using fluconazole alone (p value ⩽ 0.05). High doses of the antifungals were employed to assess the effect on the persisters' selected gene expression. Marked over expression of SKN1 and to a lesser extent KRE1 was noticed among the mature biofilms treated with AMB alone or in combination after 1 h of exposure, and SKN1 expression was even more sharply induced after 24 h. No statistically significant over expression of CDR1 was observed in biofilms after exposure to high doses of FLC, VOC or any of the combinations used.

Epidemiology of candidemia in Qatar, the Middle East: performance of MALDI-TOF MS for the identification of Candida species, species distribution, outcome, and susceptibility pattern

INTRODUCTION

Bloodstream infections (BSIs) due to Candida spp. constitute the predominant group of hospital-based fungal infections worldwide. A retrospective study evaluated the performance of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for the identification of BSI Candida isolates. The epidemiology, risk factors, demographic features, species distribution, and clinical outcome associated with candidemia in patients admitted to a single tertiary-care hospital in Qatar, were analyzed.

METHODS

A single-center, retrospective analysis covering the period from January 1, 2004 to December 31, 2010 was performed. Molecular identification used sequence analysis of the D1/D2 domains of the large subunit ribosomal DNA (LSU rDNA) and the ITS1/2 regions of the rDNA. MALDI-TOF MS-based identification of all yeast isolates was performed with the ethanol/formic acid extraction protocol according to Bruker Daltonics (Bremen, Germany). The susceptibility profiles of 201 isolates to amphotericin B, itraconazole, fluconazole, voriconazole, anidulafungin, caspofungin, posaconazole, and isavuconazole were tested using CLSI standard broth microdilution method (M27-A3 and M27 S4) guidelines. Statistical analyses were performed with the statistical package SPSS 19.0.

RESULTS

A total of 187 patients with 201 episodes of candidemia were identified. Candida albicans was the most common species isolated (33.8 %; n = 68), whereas non-albicans Candida species represented 66.2 % (n = 133) of the episodes. The species distribution and outcome of candidemia showed a difference in the crude mortality between patients infected with C. albicans (n = 30; 45.5 %) and non-albicans Candida species. For example, C. parapsilosis candidemia was associated with the lowest mortality rate (40.6 %), and patients with other non-albicans species had the highest mortality rate (68-71.4 %). High mortality rates were observed among pediatric (<1 year of age) and elderly patients (>60 years of age). All strains showed low minimum inhibitory concentrations (MICs) (MIC90 of 0.063 μg/ml) to isavuconazole. The overall resistance to voriconazole in vitro antifungal activity was 2.5 %. C. glabrata (n = 38) had an MIC90 of 8 μg/ml for fluconazole. Most yeast isolates were susceptible to anidulafungin (>99.5 %) and 81.1 % to caspofungin. Resistance to anidulafungin was detected in 1/8 (12.5 %) isolates of C. orthopsilosis. According to new Clinical and Laboratory Standards Institute (CLSI) breakpoints, C. glabrata (n = 38) showed 100 % resistance, and 37/68 (54.4 %) C. albicans isolates were susceptible dose dependent (SDD) to caspofungin. Identification by MALDI-TOF MS was in 100 % concordance with molecular identification.

CONCLUSION

The Middle East epidemiology of candidemia has a unique species distribution pattern distinct from other parts of the globe. High mortality rates were observed among pediatric (<1 year of age) and elderly patients (>60 years of age). All strains were susceptible to isavuconazole. All isolates of C.glabrata were resistant to caspofungin based on M27 S4. MALDI-TOF MS is a highly useful method for the routine identification of yeast isolates in clinical setting to achieve successful therapeutic treatment.

Clinical practice guidelines for the management of invasive Candida infections in adults in the Middle East region: Expert panel recommendations

Invasive Candida infections contribute to significant morbidity and mortality in patients with healthcare-associated infections. They represent a major burden on the public health system, and are challenging to diagnose and treat. A multidisciplinary expert panel critically reviewed available evidence to provide consensus recommendations for the management of invasive Candida infections in the Middle East. Based on diagnosis, recommendations were provided for the management of Candida infections in non-neutropenic and neutropenic patients. Polyenes (amphotericin B-deoxycholate [AmB-d] and lipid formulations amphotericin B [LFAmB]), triazoles (fluconazole, itraconazole and voriconazole), echinocandins (caspofungin, anidulafungin, and micafungin) and flucytosine are the recommended categories of antifungal agents for treatment of Candida infections. Echinocandins are preferred for treatment of proven and suspected Candida infections, especially in critically ill patients or those with previous exposure to azoles. Recommendations were also provided for infections caused by specific Candida species as well as management of different disease conditions. The experts highlighted that the guidelines should be used along with clinical judgment. Given the paucity of published data from the region, research in the form of randomized clinical trials should be given priority.

Surveillance study of species distribution, antifungal susceptibility and mortality of nosocomial candidemia in a tertiary care hospital in China

Background

Bloodstream infections due to Candida species cause significant morbidity and mortality, and the epidemiology of Candida infection is changing. Surveillance for candidemia is necessary to detect trends in species distribution and antifungal resistance.

Methods

The medical and electronic records of all patients who had candidemia at the authors’ hospital from 2009 to 2011 were reviewed for demographic data and clinical information, including the infecting Candida species, resistance to antifungals and survival, and the presence of risk factors associated with candidemia.

Results

A total of 133 distinct episodes of candidemia were identified over the study period. The annual incidence of candidemia ranged between 0.71 and 0.85 cases/1000 hospital discharges. The most frequent Candida species were C. tropicalis (28.6%), followed by C. albicans (23.3%) and C. parapsilosis (19.5%). The rates of susceptibility to antifungal agents were as followed: voriconazole (97.8%), itraconazole (69.5%), fluconazole (46.1%), ketoconazole (38.9%). Out of 131 evaluable patients, 34 (26.0%) died within 30 days from the onset of candidemia. C. tropicalis candidemia was associated with the highest mortality rate (44.7%). Regarding the crude mortality in the different units, patients in Hemato-Oncology ward had the highest mortality rate (66.7%), followed by patients in cardiovascular wards and ICU (57.1% and 25.6%, respectively). Predictors of 30-day mortality were identified by uni- and multivariate analyses. Complicated abdominal surgery, presence of central venous catheter (CVC), neutropenia, candidemia due to C. tropicalis and poor treatment with fluconazole were significantly associated with the 30-day mortality. Presence of CVC (odds ratio[OR] = 4.177; 95% confidence interval [CI] = 1.698 to 10.278; P = 0.002) was the only independent predictor for mortality in the multivariate analysis.

Conclusion

This report provides baseline data for future epidemiological and susceptibility studies and for the mortality rates associated with candidemia in our hospital. The knowledge of the local epidemiological trends in Candida species isolated in blood cultures is important to guide therapeutic choices.

Changes in the pattern of hospital intravenous antimicrobial use in Saudi Arabia, 2006-2008

BACKGROUND AND OBJECTIVE

Hospitals should measure antimicrobial use based on the WHO's recommended metric, the defined daily dose (DDD). There is no data on antimicrobial usage based on DDD in Saudi Arabia. Thus, this study evaluates the trend in antimicrobial consumption based on this concept.

DESIGN AND SETTING

Observational study in a general hospital in Saudi Arabia from 2006-2008.

METHODS

We analyzed the use of intravenous systemic antibacterial agents (group J01 of the Anatomical Therapeutic Chemical [ATC] classification and the classes of this group) that were administered to hospitalized patients by reviewing the data obtained from the pharmacy records. Antimicrobial consumption was calculated as the number of DDD per 100 bed-days.

RESULTS

Of the total parenteral antibiotics, ciprofloxacin was the most commonly used intravenous antibiotic (67.6%), followed by ceftriaxone (6%), cefazolin (5%), and imipenem-enzyme inhibitor (4.3%). The DDD per 100 patient-days usage of intravenous antimicrobial agents was as follows: J01MA02 ciprofloxacin (parenteral) 82.643, J01DD04 ceftriaxone 7.447, J01DB02 cefazolin 6.166, J01DH51 imipenem-enzyme inhibitor 5.234, J01MA12 levofloxacin 3.188, and J01XA01 vancomycin 2.97. Intravenous ciprofloxacin usage increased from 3.55 to 82.643 DDD/100 patient days.

CONCLUSION

The study showed that the most commonly used intravenous systemic antimicrobial agent was ciprofloxacin. Thus, strategies are needed to specifically target these agents for prescribing improvement.

Peripherally inserted central catheter bloodstream infection surveillance rates in an acute care setting in Saudi Arabia

BACKGROUND AND OBJECTIVE

Peripherally inserted central venous catheters (PICCs) are alternatives to short-term central venous catheters and provide intravenous access in the acute hospital setting. In this study, we describe the rate of PICC-associated bloodstream infections (BSI).

DESIGN AND SETTING

Prospective cohort study using data on PICC lines reviewed from January to December 2009.

METHODS

The infection control team was responsible for prospective BSI case findings. The infection rate was calculated per 1000 device-days.

RESULTS

During the study period, 92 PICC lines were inserted with a total of 3336 device-days of prospective surveillance. The most frequent reasons for the insertion of the PICC lines were chemotherapy (n=19, 20.7%), intravenous antimicrobial therapy (n=34, 37%), and for patients in the medical intensive care unit (ICU) (n=16, 17.4%). The overall BSI rate was 4.5/1000 PICC days. The PICC line-associated BSI rates for a specific indication were as follows: chemotherapy 6.6/1000 device-days, intravenous antimicrobial therapy 1.2/1000 device-days, medical ICU 7.3/1000 device-days, surgical ICU 4.6/1000 device-days, and total parental nutrition patients 2.4/1000 device-days (P<.001). The rates were not adjusted for patient severity of illness.

CONCLUSIONS

Our data suggest that underlying conditions and indications for the PICC line use may play an important role in the development of BSI.

A scoring model of factors associated with Candida glabrata candidemia among critically ill patients

Candida species, including Candida glabrata (CG), are common causes of bloodstream infections among intensive care unit (ICU) patients. Many CG isolates have decreased susceptibility to fluconazole. Constructing a scoring model of factors associated with CG candidemia in ICU patients that can be used if fluconazole susceptibility testing is not readily available. We identified patients with candidemia that were admitted to the ICU of the Mayo Clinic in Rochester, Minnesota from 1998 to 2006. Using patient demographical and clinical data abstracted via chart review, a multivariable logistic regression model was developed to distinguish those with CG candidemia. We identified 246 patients with candidemia including 68 CG cases. Multivariable analysis identified four independent factors associated with CG candidemia: absence of renal failure, less than 7 days in the hospital, abdominal surgery and fluconazole use. The predictive ability of the model, based on the c-statistic, was 0.727. In a large ICU cohort, a scoring model that included four risk factors, which are readily ascertainable at the bedside, was created to distinguish candidemia due to CG from other causes of candidemia. The identification of risk factors associated with CG candidemia could aid physicians in the selection of the optimal initial antifungal therapy.

Epidemiology of invasive candidiasis

PURPOSE OF REVIEW

This review covers candidaemia in numbers, susceptibility issues, host groups, risk factors and outcome.

RECENT FINDINGS

The incidence of candidaemia has increased over the last decades. Candida glabrata is particularly common in the northern hemisphere and with increasing age whilst the opposite is true for C. parapsilosis, C. glabrata, C. krusei and a number of emerging species are not fully susceptible to azoles. C. parapsilosis and C. guilliermondii are not fully susceptible to echinocandins. Increasing rates of C. parapsilosis have been observed at centres with a high use of echinocandins, and outcome for this species is not superior comparing echinocandins with fluconazole. Acquired azole resistance has recently been described in as many as a third of 19% resistant isolates and echinocandin resistance has emerged and been detected as early as day 12 of echinocandin therapy. ICU stay and abdominal surgery are among the most important risk factors. Outcome is dependent on species involved, timing, dosing and choice of therapy and management of the primary focus of infection. However, host factors are dominating predictors of mortality in recent studies of ICU candidiasis.

SUMMARY

The changing epidemiology highlights the need for close monitoring of local incidence, species distribution and susceptibility in order to optimize therapy and outcome.

Is Candida really a threat in the ICU?

PURPOSE OF REVIEW

The epidemiological and clinical relevance of Candida in the ICU is reviewed. Three issues were appraised. First is the prevalence of Candida. Second is the relevance of nonblood cultures positive for Candida and multisite colonization. Third is the importance of invasive candidiasis in terms of mortality.

RECENT FINDINGS

The diagnosis of invasive candidiasis remains problematic in nonblood cultures. Consequently, the true prevalence of invasive candidiasis is difficult to assess. Another result of the complicated diagnosis is the risk for delayed antifungal therapy in case of systemic Candida infection. Therefore, pre-emptive therapy has become increasingly popular in high-risk patients.

SUMMARY

Candida spp. cause a minority of nosocomial bloodstream infections ( approximately 4-9%). Yet, delayed initiation of appropriate antifungal therapy results in significant attributable mortality. Given the inability to efficiently discriminate colonization from invasive candidiasis, this is a problematic issue. The presence of Candida in tracheal aspirates, urine cultures or wound swabs frequently reflects colonization. Yet, multisite colonization frequently precedes systemic invasion. As such, multisite Candida colonization is a crucial element in the decision to start pre-emptive therapy. However, the predictive value of multisite colonization in the absence of an overt risk profile for invasive candidiasis appears to be low.

Candida parapsilosis, an emerging fungal pathogen

SUMMARY

Candida parapsilosis is an emerging major human pathogen that has dramatically increased in significance and prevalence over the past 2 decades, such that C. parapsilosis is now one of the leading causes of invasive candidal disease. Individuals at the highest risk for severe infection include neonates and patients in intensive care units. C. parapsilosis infections are especially associated with hyperalimentation solutions, prosthetic devices, and indwelling catheters, as well as the nosocomial spread of disease through the hands of health care workers. Factors involved in disease pathogenesis include the secretion of hydrolytic enzymes, adhesion to prosthetics, and biofilm formation. New molecular genetic tools are providing additional and much-needed information regarding C. parapsilosis virulence. The emerging information will provide a deeper understanding of C. parapsilosis pathogenesis and facilitate the development of new therapeutic approaches for treating C. parapsilosis infections.

Diffuse disseminated candidiasis in a patient with Felty's syndrome: a case report

Severe granulocytopenia predispose patients with Felty's syndrome to severe infectious diseases. The following report deals with an occurrence of chronic disseminated candidiasis in a patient with Felty's syndrome who presented with prolonged and severe granulocytopenia. To the best of our knowledge this coexistence has never been described before.
