Abstract
AbstractOver the past decade, the incidence of hospital-acquired bloodstream infections caused byCandidastrains has risen, while the implicated species have changed.Candida tropicalis, Candida parapsilosis, andCandida glabrataall have increased in incidence. Data from the Centers for Disease Control and Prevention reveal that, between 1980 and 1990,Candidaemerged as the sixth most common nosocomial pathogen (7.2.%) and was the fourth most common pathogen in nosocomial bloodstream infections, surpassed only by coagulase-negative staphylococci,Staphylococcus aureus, and enterococci. The incidence of candidemia is dramatically higher in high-risk critical-care units: 25% of cases occur in surgical intensive-care units (ICUs) versus 25% in bone marrow transplantation units, 20% in medical ICUs, 20% in general medical wards, and 10% in oncology-hematology units. Burns and gastrointestinal surgery predispose to nosocomial candidemia. Independent risk factors include prior therapy with multiple antibiotics, isolation ofCandidafrom sites other than blood, and prior hemodialysis. Crude mortality exceeds 55% and is associated with older age and concomitant renal failure, hepatic failure, acute respiratory diseases, or postoperative shock. In addition to extreme vigilance for early recognition ofCandidasepsis in critically ill surgical patients, the high risk for candidemia probably necessitates fungal surveillance cultures and initiation of preemptive antifungal therapy in high-risk surgical patients.

Abstract
OBJECTIVE Describe systemic antifungal therapy in non-neutropenic adult patients in intensive care unit (ICU). PATIENTS AND METHOD A prospective, observational study was conducted during the first half of 2010 in the 7 ICU in a hospital with medical consultant on antimicrobial therapy. All non-neutropenic consecutive adult patients receiving systemic antifungal therapy for documented or suspected invasive fungal infection (IFI) apart from aspergillosis were included. RESULTS Out of 1502 patients admitted in ICU, 104 (7 %) underwent systemic antifungal therapy, including 30 (29 %) for a documented IFI and 74 (71 %) for a suspected IFI. Candida albicans was identified in 23 (77 %) of the IFI and 45/52 (86 %) of the broncho-pulmonary and/or urinary colonizations in suspected IFI. Echinocandin was significantly more prescribed in patients with a documented infection (19/30 patients) and fluconazole in patients with a suspected infection (48/74 patients). The first line therapy was primarily stopped after recovery (11/30 patients) or de-escalation (9/30 patients) in documented infections, and for lack of indication (34/74 patients) or due to recovery (21/74 patients) in suspected infections after on average of 7 days of treatment. CONCLUSION For ICU non-neutropenic adult patients in our center, antifungal therapy is prescribed two times out of three for suspected, unproved infections, in most cases with fluconazole. Documented infections were more often treated by echinocandin with secondary de-escalation. An interventional prospective study to assess the role of antifungal pre-emptive or empirical therapy is necessary.

Abstract
BACKGROUND The pathogenesis of intra-abdominal candidiasis is poorly understood. METHODS Mice were intraperitoneally infected with Candida albicans (1 × 10(6) colony-forming units) and sterile stool. nanoString assays were used to quantitate messenger RNA for 145 C. albicans genes within the peritoneal cavity at 48 hours. RESULTS Within 6 hours after infection, mice developed peritonitis, characterized by high yeast burdens, neutrophil influx, and a pH of 7.9 within peritoneal fluid. Organ invasion by hyphae and early abscess formation were evident 6 and 24 hours after infection, respectively; abscesses resolved by day 14. nanoString assays revealed adhesion and responses to alkaline pH, osmolarity, and stress as biologic processes activated in the peritoneal cavity. Disruption of the highly-expressed gene RIM101, which encodes an alkaline-regulated transcription factor, did not impact cellular morphology but reduced both C. albicans burden during early peritonitis and C. albicans persistence within abscesses. RIM101 influenced expression of 49 genes during intra-abdominal candidiasis, including previously unidentified Rim101 targets. Overexpression of the RIM101-dependent gene SAP5, which encodes a secreted protease, restored the ability of a rim101 mutant to persist within abscesses. CONCLUSIONS A mouse model of intra-abdominal candidiasis is valuable for studying pathogenesis and C. albicans gene expression. RIM101 contributes to persistence within intra-abdominal abscesses, at least in part through activation of SAP5.

Abstract
BACKGROUND Implant breast augmentation is one of the most frequently performed surgical procedures, and fungal infection still is considered exceptional. This report presents a case of bilateral breast implant infection by multidrug-resistant Candida albicans treated with a targeted antifungal therapy. METHODS A young woman presented with breast pain and asymmetry as well as implant superficialization in the left breast 3 years after bilateral tuberous breast correction with implant insertion. She did not report any trauma to the chest wall or recent systemic infections. The breast was evaluated through mammary compliance analysis and magnetic resonance imaging (MRI). RESULTS At surgery, both implants showed capsule contracture and were surrounded by a gelatinous yellow-brown and turbid fluid, which was sent for microbial and fungal analysis. A bilateral capsulectomy was performed. After copious irrigation of the subglandular pockets, submuscular pockets were created, and implants were substituted. Culture swabs tested positive for C. albicans and showed drug resistance to amphotericin B, fluconazole, itraconazole, and voriconazole on the fungal antibiogram. Targeted antifungal therapy with caspofungin was administrated in association with oral antibiotic therapy. Follow-up assessment at 1, 3, 6, 12, and 24 months did not show any infection or contracture relapse. CONCLUSIONS This is the first report in the literature on a breast implant infection by a multidrug-resistant C. albicans. The study focused on the association between fungal contamination and capsular contracture and investigated the importance of a fungal antibiogram in cases of suspected prosthesis infection for performance of a targeted antifungal treatment.

Abstract
Despite improvements in our knowledge of the physiopathology of severe infection, diagnostic methods, antibiotic therapy, postoperative care and surgical techniques, a substantial number of patients with intraabdominal infection (IAI) will develop advanced stages of septic insult requiring admission to the intensive care unit. The success of treatment of IAI is multifactorial and the best antibiotic protocol may be insufficient unless adequate control of the focus of infection has been achieved. The present article discusses the appropriacy of empirical antibiotic therapy and the main pathogens associated with treatment failure. We also analyze the patients at risk of infection with microorganisms requiring broad-spectrum antimicrobial coverage. However, excessive antibiotic treatment, in terms of either spectrum or duration, could jeopardize future patients in an environment already threatened by the scarcity of research and development into new molecules required for the emergence of pathogens resistant to current antibiotics.

Abstract
Drug resistance among yeasts is an increasing problem. Isolates of Candida krusei and Candida glabrata are recognized as having reduced susceptibility to fluconazole and resistance to this drug has also arisen in Candida albicans isolated from AIDS patients on long term azole therapy. Candida tropicalis (CT) is being increasingly isolated from human disease and is associated with invasive infection, however, data regarding this organism's drug susceptibility is limited. We report our findings on 60 isolates of CT isolated from patients with serious infection in the North West of England. Over 60% of isolates were from adult Intensive Care Unit (ICU) patients, and almost half were from the respiratory tract. Susceptibility to fluconazole, flucytosine, itraconazole and ketoconazole were tested by standardised methods - 48% of the isolates were resistant to fluconazole (MIC > 12.5 mg/l), and 10% had intermediate susceptibility (MIC 6.25-12.5 mg/l). For flucytosine 17% of isolates were resistant (MIC > 8 mg/l) and 22% had intermediate susceptibility (MIC 2-8 mg/l). Three isolates were resistant to both drugs. For itraconazole 17% of isolates were resistant (MIC > 1 mg/l), and 12% showed intermediate susceptibility (MIC 0.5-1 mg/l). Resistance to ketoconazole was seen in 33% of isolates (MIC > 1 mg/l) and 10% showed intermediate susceptibility (MIC 0.5-1 mg/l). Differences in the degree of cross resistance between the azole drugs was observed. Candida tropicalis should be added to the list of yeasts in which drug resistance is commonly found. Given the high invasiveness of Candida tropicalis, its affinity for patients on ICU and the high incidence of drug resistance in this species, identification and susceptibility tests should be performed on all yeast isolates from patients on ICU.

Abstract
The epidemiology of Candida infection in intensive care units (ICUs) and the management strategies for such infections in non-neutropenic intensive care patients are discussed in this review. Candida species are one of the leading causes of nosocomial bloodstream infections and a significant cause of morbidity in patients admitted to the ICU. Prophylactic, pre-emptive and empiric treatment strategies for Candida infections have been explored in ICU patients. Routine prophylaxis should not be administered to the whole population of ICU patients, because the concerns about the selection of azole-resistant Candida strains or the induction of resistance are justified. Treatment of fungal infections is now possible with newer antifungal agents, including newer azoles (e.g., voriconazole, posaconazole) and echinocandins (e.g., micafungin, anidulafungin). However, there is a critical need for improvement in diagnosis of invasive Candida infection in order to provide clinicians the opportunity to intervene earlier in the diseases course.

Abstract
BACKGROUND The Japanese Guidelines for the Diagnosis and Treatment of Deep-Seated Mycosis were established in 2003. Proven Candida infection (CI) is defined as at least one positive blood culture yielding a Candida species. Clinically documented CI requires documentation of more than 2 sites of colonization and a positive plasma beta-D-glucan test. Possible CI is diagnosed by one of the above criteria in febrile, nonneutropenic critically ill patients. OBJECTIVE To assess the use of definitions of clinically documented and possible CI for guiding preemptive antifungal therapy in critically ill patients. METHODS The patients treated in our intensive care unit (ICU) for at least 48 hours between 2000 and 2004 were investigated. The administration of antifungal agents and ICU mortality were compared among proven, clinically documented, and possible CI groups for age, sex, APACHE II score, diagnosis, length of ICU stay, treatment, number of colonization sites, and plasma beta-D-glucan level. RESULTS Six patients were diagnosed with proven CI, 25 were diagnosed with clinically documented CI, and 104 with possible CI. The patients with clinically documented CI were compared with those with possible CI, and statistically significant differences were found in the following variables: APACHE II score (p = 0.018), length of ICU stay (p < 0.01), use of ventilator (p = 0.027), tracheotomy (p = 0.027), number of colonization sites (p < 0.001), plasma beta-D-glucan level (p < 0.001), and administration of antifungal agents (p < 0.001); incidence of mortality was not statistically significant (p = 0.33). The shorter length of ICU stay, use of ventilator, and continuous hemodiafiltration were risk factors for death after adjusting for APACHE II score, admission before/after 2003, antifungal therapy, and other factors. Although the frequency of the administration of preemptive antifungal therapy was higher after 2003 than before, the mortality rate did not differ significantly. CONCLUSIONS The use of the definitions of clinically documented and possible CI may be beneficial for determining when it is appropriate to initiate preemptive antifungal therapy. However, use of the guidelines did not lead to prevention of possible CI proceeding to clinically documented CI or to improved mortality.

Abstract
OBJECTIVES To study the relation between serum and peritoneal levels of amphotericin B and flucytosine during intravenous treatment in patients with abdominal sepsis due to a perforated gut. PATIENTS AND METHODS Included were consecutive patients with abdominal sepsis due to a perforated gut, who were treated intravenously with amphotericin B and/or flucytosine after surgery if an abdominal drain was present. Amphotericin B and flucytosine were measured from simultaneously collected serum and abdominal fluid samples. RESULTS Twenty-one consecutive patients were included. Five repeated samples were taken from three patients. The time interval between the start of the medication and the first sampling was median 4.0 days (range 2-7 days). The correlation coefficient (r(2)) between serum and peritoneal levels of amphotericin B was 0.79. In nine patients (43%) with a maximum serum level of 0.28 mg/L, amphotericin B in the peritoneal fluid was undetectable. The lowest serum level that was present with a detectable peritoneal level was 0.16 mg/L. A short duration of treatment (2 days) was associated with low serum and undetectable peritoneal levels. In seven patients, flucytosine levels were measured. Peritoneal flucytosine levels did not differ significantly from serum levels. Serum and peritoneal flucytosine levels correlated well with r(2)=0.88. Peritoneal amphotericin B level was inversely correlated with C-reactive protein level on the same day (r(2)=0.30). CONCLUSIONS It is shown, during continuous infusion, that peritoneal levels of amphotericin B are lower than serum levels. The amphotericin B serum levels should exceed 0.5 mg/L to obtain peritoneal levels above MIC values. Flucytosine levels in the abdominal fluid are comparable to serum levels and within MIC ranges.

Abstract
5-flucytosine (5-FC) is an antifungal drug used for the treatment of serious infections caused by Candida or Cryptococcus spp. In the UK, the recommended pre- and post-dose serum therapeutic ranges are 30-40 mg/L and 70-80 mg/L, respectively. A 12-year retrospective review of serum concentrations of 5-FC in three groups of children aged 1-30 days (n=167), 31-60 days (n=102) and 91 days to 12 years (n=122) was conducted. In these three age groups, 65.1%, 44.4% and 21.3% of pre-dose samples and 39.3%, 29.2% and 19.7% of post-dose samples were above the recommended ranges. Both the mean concentration and the percentage of concentrations above the recommended ranges were significantly higher in the youngest age group (1-30 days old), suggesting that the standard dose of 100 mg/kg daily may not be an appropriate dose in this age group.

Abstract
This study aimed to determine whether candiduria is associated with the occurrence of nosocomial candidaemia. In the case-control part of the study, 115 cases (nosocomial candidaemia) and 115 controls (nosocomial bacteraemia) were similar in age, severity of condition and time of hospitalisation. There was a significant association of candidaemia with candiduria (OR 9.79; 95% CI 2.14-44.76). In the microbiology part of the study, 23 pairs of Candida-positive urine and blood cultures were obtained from 23 patients. In ten (43%) cases, the urine and blood culture isolates belonged to different species, and molecular typing showed a difference in two of the 13 cases yielding the same species from both specimens. Overall, there was a significant association between candiduria and candidaemia, but the Candida isolates from urine and blood were different for 52% of the patients. Thus, the data indicated that the urinary tract was probably not a source for the candidaemia.

Abstract
In critically ill non neutropenic patients there are four broad approaches for the management of antifungal treatment for invasive candidiasis: prophylaxis, empirical, preemptive therapy and treatment of established infections. All these approaches in relationship with risk strategies and microbiological indirect laboratory techniques for establishing invasive candidiasis will be discussed.

Abstract
OBJECTIVE The clinical significance of Candida cultured from peritoneal fluid specimens remains a matter of debate. None of the studies that have addressed this issue have clearly distinguished between community-acquired peritonitis and nosocomial peritonitis. The current study tried to differentiate the pathogenic role of Candida in these two clinical settings and assess its importance on outcome. DESIGN A multiple-center, retrospective, case-control study was conducted in intensive care unit patients. The interaction between mortality rates and type of patients was assessed. In the case of a significant interaction, a separate analysis of mortality and morbidity was planned. SETTING Seventeen intensive care units in teaching and nonteaching hospitals. PATIENTS Cases were patients operated on for peritonitis with Candida cultured from the peritoneal fluid, whereas controls were operated patients free from yeast. Cases and controls were matched for type of infection, Simplified Acute Physiology Score II, age, and time period of hospitalization. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The following characteristics were collected: demographic variables, underlying disease, severity score, site of infection, microbiological features, and anti-infective treatments. Survival was defined as the main outcome criterion and morbidity variables as secondary criteria. Odds ratios of mortality were calculated. Matching was achieved in 91 cases and 168 controls. Matching criteria, clinical characteristics, and mortality rate were not statistically different between cases and controls. A significant interaction was demonstrated between mortality rates and type of infection, leading to separate analysis of patients with community-acquired peritonitis and nosocomial peritonitis. The subgroup analysis demonstrated an increased mortality rate only in nosocomial peritonitis with fungal isolates (48% vs. 28% in controls, p<.01). Upper gastrointestinal tract site (odds ratio, 4.9; 95% confidence interval, 1.6-14.8) and isolation of Candida species (odds ratio, 3.0; 95% confidence interval, 1.3-6.7, p<.001) were found to be independent risk factors of mortality in nosocomial peritonitis patients. CONCLUSIONS Isolation of Candida species appears to be an independent risk factor of mortality in nosocomial peritonitis but not in community-acquired peritonitis.

Abstract
BACKGROUND Recovery of Candida from the respiratory tract of a critically ill patient receiving mechanical ventilation (MV) usually indicates colonization rather than infection of the respiratory tract. However, interactions between Candida and bacteria, particularly Pseudomonas, have been reported. Thus, Candida colonization of the respiratory tract may predispose to bacterial ventilator-associated pneumonia (VAP). METHODS In a multicenter study of immunocompetent critically ill patients receiving MV for > 2 days, we compared the incidence of pneumonia in patients with and without (exposed/unexposed) respiratory-tract Candida colonization, matched on study center, admission year, and MV duration. RESULTS Over the 4-year study period, of the 803 patients meeting study inclusion criteria in the six study centers, 214 patients (26.6%) had respiratory tract Candida colonization. Candida albicans was the most common species (68.7%), followed by Candida glabrata (20.1%) and Candida tropicalis (13.1%). Extrapulmonary Candida colonization was more common in exposed patients (39.7% vs 8.3%, p = 0.01). Exposed patients had longer ICU and hospital stays but similar mortality to unexposed patients. The matched exposed/unexposed nested cohort study identified bronchial Candida colonization as an independent risk factor for pneumonia (24.1% vs 17.6%; adjusted odds ratio [OR], 1.58; 95% confidence interval [CI], 0.94 to 2.68; p = 0.0860); the risk increase was greatest for Pseudomonas pneumonia (9% vs 4.8%; adjusted OR, 2.22; 95% CI, 1.00 to 4.92; p = 0.049). CONCLUSIONS Candida colonization of the respiratory tract is common in patients receiving MV for > 2 days and is associated with prolonged ICU and hospital stays, and with an increased risk of Pseudomonas VAP.

Abstract
OBJECTIVE To compare the management of invasive candidiasis between infectious disease and critical care specialists. DESIGN AND SETTING Clinical case scenarios of invasive candidiasis were presented during interactive sessions at national specialty meetings. Participants responded to questions using an anonymous electronic voting system. PATIENTS AND PARTICIPANTS Sixty-five infectious disease and 51 critical care physicians in Switzerland. RESULTS Critical care specialists were more likely to ask advice from a colleague with expertise in the field of fungal infections to treat Candida glabrata (19.5% vs. 3.5%) and C. krusei (36.4% vs. 3.3%) candidemia. Most participants reported that they would change or remove a central venous catheter in the presence of candidemia, but 77.1% of critical care specialists would start concomitant antifungal treatment, compared to only 50% of infectious disease specialists. Similarly, more critical care specialists would start antifungal prophylaxis when Candida spp. are isolated from the peritoneal fluid at time of surgery for peritonitis resulting from bowel perforation (22.2% vs. 7.2%). The two groups equally considered Candida spp. as pathogens in tertiary peritonitis, but critical care specialists would more frequently use amphotericin B than fluconazole, caspofungin, or voriconazole. In mechanically ventilated patients the isolation of 10(4) Candida spp. from a bronchoalveolar lavage was considered a colonizing organism by 94.9% of infectious disease, compared to 46.8% of critical care specialists, with a marked difference in the use of antifungal agents (5.1% vs. 51%). CONCLUSIONS These data highlight differences between management approaches for candidiasis in two groups of specialists, particularly in the reported use of antifungals.

Abstract
OBJECTIVE To determine whether systemic antifungal prophylaxis decreases infectious morbidity and mortality in nonneutropenic, critically ill, trauma and surgical intensive care unit (ICU) adult patients. DESIGN Systematic review and meta-analysis of randomized clinical trials. We used a fixed effect model, with risk ratio (RR) and 95% confidence intervals (CI). PARTICIPANTS Patients admitted to ICU after surgery or trauma, with multiple risk factors for fungal infections. INTERVENTIONS Nine studies (seven double blind) with a total of 1,226 patients compared ketoconazole (three) or fluconazole (six) to placebo (eight) or no treatment (one). RESULTS Prophylaxis with azole was associated with reduced rates of candidemia (RR 0.30, 95% CI 0.10-0.82), mortality attributable to Candida infection (RR 0.25, 95% CI 0.08-0.80), and overall mortality (RR 0.60, 95% CI 0.45-0.81). Time to event analysis showed a significantly lower probability of fungal infections in treated patients. There was no evidence of statistical heterogeneity between studies, and publication bias assessment gave a negative results. There was, however, wide variability in the definition and reporting of some relevant clinical outcomes (e.g., confirmed or suspected infections, colonization) and pooling of these outcome measures was not feasible. CONCLUSIONS Prophylaxis of candidal infection among critically ill ICU patients has beneficial effect on certain outcome measures, but additional data from well designed clinical trials and long-term epidemiological observations are needed to provide firm recommendations for the selection of subgroups of patients who would most benefit from prophylaxis and to determine the effect of prophylaxis on fungal resistance patterns.

Abstract
Candida species have become predominant pathogens in critically ill patients. In this population, invasive candidiasis is associated with a poor prognosis but adequate management can limit the attributable mortality. Adequate management, however, is hampered by a problematic diagnosis as the clinical picture of invasive disease is non-specific and blood cultures have a low sensitivity. Moreover, it is often hard to differentiate colonisation from infection and many critically ill patients are heavily colonised with Candida species, especially when receiving broad-spectrum antibacterials. The question of which antifungal agent to choose has become more complex as the development of new drugs raises promising expectations. Until the 1980s therapy for invasive candidiasis was limited to amphotericin B, but with the advent of new antifungal agents, such as azoles and echinocandins, less toxic therapeutic options are possible and doors have opened towards prevention and optimised therapy in the case of documented candidiasis. Through the arrival of these new antifungal agents, a range of therapeutic strategies for the management of invasive candidiasis has been developed: antifungal prophylaxis, pre-emptive therapy, and empirical and definitive antifungal therapy. Each of these strategies has a specific target population, as defined by specific underlying conditions and/or individual risk factors. Antifungal prophylaxis, in order to prevent candidal infection, is based on the type of underlying diseases with a high risk for invasive candidiasis. Individual risk factors are not taken into account. Potential indications are bone marrow transplantation, liver transplantation, recurrent gastrointestinal perforations or leakages, and surgery for acute necrotising pancreatitis. Pre-emptive therapy is also a preventive strategy. It can be recommended on the basis of an individual risk profile including overt candidal colonisation. Empirical therapy is started in patients with a risk profile for invasive candidiasis. It is recommended in the presence of clinical signs of infection, deteriorating clinical parameters, or a clinical picture of infection not responding to antibacterials but in the absence of a clear causative pathogen. Definitive antifungal therapy is defined as therapy in patients with documented invasive infection. The main goal is to maintain a balance between optimal prevention and timely initiation of therapy on one hand, and to minimise selection pressure in order to avoid a shift towards less susceptible Candida species on the other hand.

Abstract
This prospective study evaluated Raman spectroscopy for the identification of clinically relevant Candida spp. in peritonitis patients. A Raman database was developed by measuring spectra from 93 reference strains belonging to ten different Candida spp. Clinical samples were obtained from the surgical department and intensive care unit of a tertiary university hospital. In total, 88 peritoneal specimens from 45 patients with primary, secondary or tertiary peritonitis were included. Specimens were cultured initially on a selective Sabouraud medium that contained gentamicin to suppress bacterial growth. For conventional identification, a chromogenic medium was used for presumptive identification, followed by use of the Vitek 2 system for definitive identification (requiring a total time of 48-96 h). Raman measurements were taken on overnight cultures from Sabouraud-gentamicin medium. Thirty-one samples were positive for Candida by culture. Using multivariate statistical analyses, a prediction accuracy of 90% was obtained for Raman spectroscopy, which appears to offer an accurate and rapid (12-24 h) alternative for the identification of Candida spp. in peritonitis patients. The reduced turn-around time is of great clinical importance for the treatment of critically ill patients with invasive candidiasis in intensive care units.

Abstract
This review addresses trends in outcome and risk factors for invasive fungal infections, current antifungal agents and new therapeutic strategies. Current prospects for new therapies rest upon caspofungin, the first of a new class of antifungal molecules, the echinocandins, and new extended-spectrum azoles, voriconazole, posaconazole and ravuconazole. Approval by the Food and Drug Administration of the USA and the European Medicine Agency was given in 2001-2002 to voriconazole and caspofungin. Voriconazole clearly demonstrated a decrease in mortality in invasive aspergillosis and fusariosis fungal infections.

Abstract
Continuous ambulatory peritoneal dialysis (CAPD) is a widespread method of treatment used in approximately 10% of all patients suffering from terminal renal insufficiency. The main problem of this procedure is the increased risk of peritoneal infection. The incidence of such a peritonitis is quoted at one episode per 13-18.4 months of treatment. Candida peritonitis is a particularly severe form of CAPD peritonitis. This is a nosocomial infection with a high lethality rate of about 60%. The incidence of Candida peritonitis in CAPD patients amounts to approximately 5% of all intraabdominal infections and is on the increase. The authors describe a severe case of Candida peritonitis in a patient on CAPD. The therapeutic concept of this severe illness is illustrated.

Abstract
OBJECTIVE Multiple-site colonization with Candida species is commonly recognized as a major risk factor for invasive fungal infection in critically ill patients. The fungal colonization density could be of predictive value for the diagnosis of systemic candidiasis in high-risk surgical patients. Little is known about it in the medical ICU setting. DESIGN AND SETTING Prospective observational study in the eight-bed medical intensive care unit of a teaching hospital. SUBJECTS 92 consecutive nonneutropenic patients hospitalized for more than 7 days. MEASUREMENTS AND RESULTS The colonization index (ratio of the number of culture-positive surveillance sites for Candida spp. to the number of sites cultured) was calculated weekly upon ICU admission until death or discharge. The 0.50 threshold was reached in 36 (39.1%) patients, almost exclusively in those with detectable fungal colonization upon ICU admission. The duration of broad-spectrum antibiotic therapy was found to be the main factor that independently promoted fungal growth as measured through the colonization index. CONCLUSIONS Candida spp. multiple-site colonization is frequently met among the critically ill medical patients. Broad-spectrum antibiotic therapy was found to promote fungal growth in patients with prior colonization. Since most of the invasive candidiasis in the ICU setting are thought to be subsequent to colonization in high-risk patients, reducing antibiotic use could be useful in preventing fungal infections.

Abstract
Fosfluconazole is a phosphate prodrug of fluconazole that has been developed to reduce the volume of fluid required to administer fluconazole by the intravenous route. Fosfluconazole is hydrolyzed by alkaline phosphatase to fluconazole and phosphoric acid. Fosfluconazole had no significant antifungal activity in vitro. However, in rat models of acute systemic candidiasis and intracranial cryptococcosis, fosfluconazole retained the antifungal potency and efficacy of fluconazole. This reflects the effective conversion of the prodrug to the parent during the course of the experiments. The 2-day-loading dose regimen led to earlier achievement of target fluconazole steady state plasma concentrations compared to use of the 1-day- or no-loading dose regimen of fosfluconazole. The efficacy and safety of fosfluconazole were investigated with the 2-day-loading dose regimen in patients with deep-seated mycosis caused by Candida and Cryptococcus species. The efficacy rates were 73.8% in the domestic Phase III study and 91.7% in the foreign Phase III study. Adverse events were observed in 31 cases (19.4%) out of 160 in both studies. These results indicate that fosfluconazole is effective for the treatment of deep-seated mycosis and shows no clinically significant adverse events in the Phase III studies

Abstract
The purpose of the study was to investigate whether examination for plasma beta-D-glucan, a cell wall constituent of fungi, is useful for selecting surgical patients with Candida colonization who would benefit from empiric antifungal therapy. We administered fluconazole to postoperative patients with Candida colonization who have risk factors for candidemia and complained of persistent fever despite prolonged antibacterial therapy. We then analyzed the clinical outcomes regarding the number of sites colonized with Candida spp. and plasma beta-D-glucan. Of the 32 patients positive for alpha-D-glucan, 15 (46.9%) responded to the empiric therapy; only 9% of those who were negative responded (p < 0.01). In the multiple logistic regression analysis, being positive for alpha-D-glucan was a significant factor predicting response, with an adjusted odds ratio of 12.9 in patients with Candida colonization [95% confidence interval (CI) 2.07-80.73) (p < 0.01). In addition, the number of sites colonized with Candida spp. was a significant factor predicting response, with an estimated exposure odds ratio of 7.57 for those who were colonized at three or more sites compared with those colonized at one site (95% CI 1.20-47.70) (p = 0.031). In patients with Candida colonization, assessment of beta-D-glucan was useful for deciding whether to start empiric therapy for suspected candidiasis in surgical patients.

Abstract
OBJECTIVES Our primary goal was to evaluate the impact on in-hospital mortality rate of adequate empirical antibiotic therapy, after controlling for confounding variables, in a cohort of patients admitted to the intensive care unit (ICU) with sepsis. The impact of adequate empirical antibiotic therapy on early (<3 days), 28-day, and 60-day mortality rates also was assessed. We determined the risk factors for inadequate empirical antibiotic therapy. DESIGN Prospective cohort study. SETTING ICU of a tertiary hospital. PATIENTS All the patients meeting criteria for sepsis at admission to the ICU. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Four hundred and six patients were included. Microbiological documentation of sepsis was obtained in 67% of the patients. At ICU admission, sepsis was present in 105 patients (25.9%), severe sepsis in 116 (28.6%), and septic shock in 185 (45.6%). By multivariate analysis, predictors of in-hospital mortality were Sepsis-related Organ Failure Assessment (SOFA) score at ICU admission (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.19-1.40), the increase in SOFA score over the first 3 days in the ICU (OR, 1.40; 95% CI, 1.19-1.65), respiratory failure within the first 24 hrs in the ICU (OR, 3.12; 95% CI, 1.54-6.33), and inadequate empirical antimicrobial therapy in patients with "nonsurgical sepsis" (OR, 8.14; 95% CI, 1.98-33.5), whereas adequate empirical antimicrobial therapy in "surgical sepsis" (OR, 0.37; 95% CI, 0.18-0.77) and urologic sepsis (OR, 0.14; 95% CI, 0.05-0.41) was a protective factor. Regarding early mortality (<3 days), factors associated with fatality were immunosuppression (OR, 4.57; 95% CI, 1.69-13.87), chronic cardiac failure (OR, 9.83; 95% CI, 1.98-48.69) renal failure within the first 24 hrs in the unit (OR, 8.63; 95% CI, 3.31-22.46), and respiratory failure within the first 24 hrs in the ICU (OR, 12.35; 95% CI, 4.50-33.85). Fungal infection (OR, 47.32; 95% CI, 5.56-200.97) and previous antibiotic therapy within the last month (OR, 2.23; 95% CI, 1.1-5.45) were independent variables related to administration of inadequate antibiotic therapy. CONCLUSIONS In patients admitted to the ICU for sepsis, the adequacy of initial empirical antimicrobial treatment is crucial in terms of outcome, although early mortality rate was unaffected by the appropriateness of empirical antibiotic therapy.

Abstract
We discuss two cases of abdominal candidiasis in critically ill patients with multiple organ failure and sepsis. Microbiological and clinical courses remained unresponsive to apparently appropriate antifungal therapy with azole or polyene derivatives. Both microbiological and clinical outcomes dramatically improved after starting caspofungin therapy. Lack of cross-resistance, lack of toxicity and potent fungicidal activity make caspofungin a very attractive drug in life threatening abdominal candidiasis. The optimal treatment of life threatening candidiasis remains a controversial issue. Because of recent advances in the field, we propose a critical review of the problem of refractory candidiasis.

Abstract
Invasive candidiasis is a feared infection with mortality similar to that of septic shock (40-60%). Improved knowledge of its pathophysiology and the availability of new compounds for antifungal therapy and prophylaxis have contributed to improving the prognosis of severe candidal infections among immunosuppressed patients at the possible cost of the emergence of non-albicans strains of candida with lower susceptibility to azoles. This review focuses on the management of invasive deep-seated candidiasis in critically ill, non-immunocompromised patients. We discuss antifungal use, indications, potential benefit, and main secondary effects. Prevention strategies include pre-emptive antifungal therapy and azole-based prophylaxis. For patients at lower initial risk, pre-emptive therapy should be based on a management strategy that takes into account the presence of definite risk factors and the dynamics of candida colonisation. Among critically ill patients, azole prophylaxis is effective and is not associated with acquisition of resistance; it must be restricted to highly selected groups of patients at high risk only.

Abstract
A substantial proportion of patients become colonised with Candida spp during hospital stay, but only few subsequently develop severe infection. Clinical signs of severe infection manifest early but lack specificity until late in the course of the disease, thus representing a particular challenge for diagnosis. Mostly nosocomial, invasive candidiasis occurs in only 1-8% of patients admitted to hospitals, but in around 10% of patients housed in intensive care units where it can represent up to 15% of all nosocomial infections. We review the epidemiology of invasive candidiasis in non-immunocompromised, critically ill patients with special emphasis on disease trends over time, pathophysiology, diagnostic approach, risk factors, and impact. Recent epidemiological data suggesting that the emergence of non-albicans candida strains with reduced susceptibility to azoles, previously linked to the use of new antifungals for empiric and prophylactic therapy in immunocompromised patients, may not have occurred in the critically ill. Management of invasive candidiasis in these patients will be addressed in the December issue of The Lancet Infectious Diseases.

Abstract
Invasive candidiasis is a condition of major medical importance. Its incidence has increased dramatically over the last 50 years, reflecting increasingly interventional standards of medical care. Candida spp. are regularly reported to be the fourth commonest cause of bloodstream infection, and it is perceived that the incidence of invasive Candida spp. infections continues to increase. The global disease burden of invasive Candida spp. infections is difficult to quantify because of wide geographic variation. Data originating from the United States indicate that mortality from candidiasis has been falling since 1989. Data from several locations have shown that the dramatic increases in Candida spp. bloodstream infections seen during the 1980s were not sustained through the 1990s. Some authors have reported a decreasing incidence. The contribution of non-albicans Candida spp. to invasive infection is rising. Invasive infections with Candida spp. continue to represent a major economic burden, increasing both mortality and morbidity in an already expensive group of hospital patients. There remains much scope for ongoing and future research into the epidemiology and basic disease processes underlying these infections.

Abstract
Fluconazole, a triazole, inhibits synthesis of ergosterol. The key enzyme of antifungal activity is C-14-Demethylase, which itself depends on Cytochrom-P-450. So drugs that inhibit or induce this enzyme lead to interactions that have to be considered when dosing fluconazole. Oral bioavailability is more than 90% after a 50 mg dose, peak levels are reached after 0.5-1.5 h (empty stomach) or 4 h (with nutrition). A loading dose on the first day leads to steady state levels on the second day. Because of the hydrophilic properties fluconazole penetrates very well into body fluids and tissues. With the M27 method conditions regarding susceptibility testing have been standardized and minimal inhibitory concentrations (MICs) have been established for fluconazole. The linear relation between dose and concentration offers the possibility to treat less susceptible fungi with higher doses, but only when MICs correlate with efficacy and higher doses are tolerated as well. Prospectively randomized studies are rare. With the limited data indications as consensus recommendations are demonstrated. Data regarding high dose therapy with fluconazole in surgical or intensive care patients demonstrate efficacy and tolerability. In addition dosage has to be adjusted in case of haemofiltration or haemodialysis. At last future options for high dose fluconazole are discussed.

Abstract
Deep-seated Candida infections are strongly associated with mortality and morbidity of patients, and need early diagnosis. The frequency of deep-seated fungal infection has recently been growing. We encountered a tuboovarian abscess caused by Candida glabrata after chemotherapy with an anticancer drug, methotrexate, in a febrile neutropenic patient. The susceptibilities to fluconazole and amphotericin B were 16 and 0.5 micro g/ml, respectively. Although combination therapy of fluconazole and amphotericin B was effective, left salpingectomy was laparoscopically performed because the left adnexal tumor continued to exist asymptomatically after 1 month.

Abstract
The combined detection of Candida antigen and antibody for the determination of systemic Candida infections (SCI) was investigated. One hundred and four patients from the intensive care unit (ICU) were analysed. Seventeen of the patients were suspected of having SCI, based on clinical and laboratory criteria. In these patients, Candida antigens and antibodies were analysed extensively. Ten patients had a positive Candida antigen (titre >1:16) determined by the latex agglutination assay Cand-Tec(R) and their median antibody titre was 1:160 in the indirect haemagglutination test (HAT). Seven antigen-negative patients had a median titre of 1:1280 (HAT). Forty-one of 42 colonized control patients had negative antigen titres and a median antibody titre of 1:160. The sensitivities and specificities were 58.8% and 97.6% for antigenemia, and 52.9% and 85.7% for antibody detection. These values reached 100.0% and 83.3%, respectively, when the results of both tests were combined. This indicates a high degree of concordance between serological results (Candida antigen and/or antibodies) and clinical presentation. We conclude, that the combined investigation of antigen and antibody titres might be a helpful tool in the characterization of SCI in ICU patients, if antigen titres are >or=1:16 or antibody titres (HAT) are >or=1:640.

Abstract
Clinicians are increasingly aware that fungal pathogens are a significant cause of morbidity and mortality in hospitalized patients. Historically, these infections occurred in severely immunocompromised patients who were undergoing treatment for hematological malignancy or solid organ transplantation. Currently, however, systemic fungal infections are commonly seen in debilitated patients who are being nursed in intensive care or high-dependency units. These infections are mostly caused by Candida albicans but there is a growing proportion of strains of non- albicans Candida spp, some with reduced susceptibility to commonly used antifungals. The limited armamentarium of antifungal agents to date has meant that amphotericin B continues to be considered the most effective therapeutic agent albeit with a poor record of treatment-limiting side effects. The past decade has seen some encouraging developments in antifungal therapy. Three lipid formulations of amphotericin B showing reduced toxicity compared with the desoxycholate formulation are now licensed. There are three investigational triazoles currently undergoing evaluation that should prove important additions to existing members of this class. The echinocandin caspofungin is the first of a new class of antifungal agents with a novel mode of action, which has recently been approved for use in the United States.

Abstract
To assess risk factors for development of candidal blood stream infections (CBSIs), a prospective cohort study was performed at 6 sites that involved all patients admitted to the surgical intensive care unit (SICU) for >48 h over a 2-year period. Among 4276 such patients, 42 CBSIs occurred (9.82 CBSIs per 1000 admissions). The overall incidence was 0.98 CBSIs per 1000 patient days and 1.42 per 1000 SICU days with a central venous catheter in place. In multivariate analysis, factors independently associated with increased risk of CBSI included prior surgery (relative risk [RR], 7.3), acute renal failure (RR, 4.2), receipt of parenteral nutrition (RR, 3.6), and, for patients who had undergone surgery, presence of a triple lumen catheter (RR, 5.4). Receipt of an antifungal agent was associated with decreased risk (RR, 0.3). Prospective clinical studies are needed to identify which antifungal agents are most protective and which high-risk patients will benefit from antifungal prophylaxis.

Abstract
Antifungal prophylaxis is regularly used during treatment of patients with some cancers, as subgroups with high rates of invasive fungal infections are readily identified; for these patients, prophylaxis has been shown to be of value. High-risk liver transplant recipients also benefit from antifungal prophylaxis. Although the idea of extending this concept to the prevention of candidal infections in the larger population of critically ill patients who are seen in the intensive care unit (ICU) and who do not have neutropenia is attractive, implementation of this strategy is difficult because of the widely varying characteristics of patients in the ICU. Two studies have shown the benefit of such prophylaxis, but the benefit was shown only in selected groups of patients who had an unusually high risk for invasive candidiasis. Although the concept is sound, broad-scale implementation of antifungal prophylaxis would be premature and costly, both financially and with regard to resistance and toxicity. Investigations are needed to define and prove the utility of predictive tools for the identification of patients in the ICU who would benefit from prophylaxis.

Abstract
Invasive candidiasis is a dread complication in hospitalized patients, characterized by a mortality comparable to that of septic shock (40% to 60%). Its incidence in hospitalized patients is 0.5/1000 admissions, but it complicates about 10 per 1,000 admissions in critical care where it represents 10% to 15% of all nosocomial infections. Although a high proportion of hospitalized patients may become colonized with Candida spp, the clinical signs of infection manifest only late, rending it difficult to diagnose. A better knowledge of their pathophysiology and the availability of triazoles compounds, less toxic than amphotericin B, allowed the concept of early empirical or preemptive treatment. These strategies are based on the prompt identification of risk factors and require continuous attention from skilled physicians. However, the prescription of triazoles has to be restricted to carefully selected groups of patients to avoid the emergence and the dissemination of resistant strains.

Abstract
The incidence of deep-seated candidal infection is increasing, but candidal vertebral osteomyelitis is still rare. We describe 6 patients recently treated in our hospital. Conservative treatment failed in all. We reviewed the literature and identified 59 additional cases of candidal vertebral osteomyelitis. Candidemia was documented in 61.5% of them. The interval between the diagnosis of candidemia and the onset of symptoms of vertebral osteomyelitis varied widely, from days to >1 year. In patients without documented candidemia, there was a similar interval between the occurrence of risk factors for candidemia (present in 72% of the patients) and the onset of symptoms of vertebral osteomyelitis. Clinical, laboratory, and radiological findings are not specific for candidal spondylodiskitis. Final diagnosis is determined by means of culture of a biopsy specimen from the infected vertebra or disk. Treatment consisted of prolonged antifungal treatment, and it often included surgery. On the basis of our experience (for all 6 patients, initial conservative treatment with only antifungals failed), we recommend consideration of early surgical debridement in combination with prolonged antifungal therapy.

Abstract
We describe a case of pacemaker infection due to two fungal species: Candida albicans and C. glabrata. Transthoracic echocardiography showed a large vegetation on the intraventricular wires. Because of severe underlying diseases, surgery was believed to be contraindicated. The patient was treated using high dose of fluconazole, resulting in clinical improvement and negative blood cultures. However, 2 months later, the patient underwent a fatal stroke. At autopsy, a large vegetation was found only all along the wires. Postmortem culture of the infected material was positive for both C. albicans and C. glabrata.

Abstract
Invasive candidiasis is a life threatening complication for intensive care unit (ICU) patients. The infection is difficult to recognise so that treatment may be delayed or even not given. Risk factors for candidiasis include the use of antimicrobial agents, central intravascular devices (mainly Hickmann catheters), recurrent gastrointestinal perforations, surgery for acute pancreatitis or splenectomy and renal dysfunction or haemodialysis. Therapy against Candida spp is recommended in ICU patients with endophthalmitis or chorioretinitis possibly caused by Candida spp., in symptomatic patients with risk factors for invasive candidiasis especially if two or more anatomical sites are colonised and for asymptomatic high-risk surgical patients (with recent abdominal surgery or recurrent gastrointestinal perforations or anastomotic leakages). The isolation of Candida from any site poses an increased risk but there are a few microbiological data that might help to establish the predictive value of a particular isolate. These include the site of isolation, the number of culture positive, noncontigous sites, the density of colonisation and the species isolated. Antifungals should be started when Candida spp. are recovered from blood cultures or from usually sterile body fluids, abscesses or wounds in burns patients. They should also be considered in patients with a colonisation index >0.5 or a corrected colonization index >0.4 or when the isolate is identified as Candida tropicalis.

Abstract
For this review, 78 studies regarding the use of fluconazole in a total of 726 children below 1 year of age were evaluated. The range of fluconazole dosage was 2-50 mg kg-1 day-1, with 162 days being the maximum duration of treatment. According to current experience, fluconazole seems to be well tolerated and efficacious against systemic candidosis and candidaemia in children below 1 year of age, including neonates and very low-birthweight infants (VLBWIs). The recommended daily dosage is 6 mg kg-1. (In Germany, fluconazole is approved for children between 1 and 16 years in cases in which there is no therapeutic alternative for treatment of systemic infections caused by Candida spp. and Cryptococcus neoformans in a dosage of 3-6 mg kg-1 day-1 and for superficial Candida infections in a dosage of 1-2 mg kg-1 day-1.) In patients with impaired renal function, the daily dose should be reduced in accordance with the guidelines given for adults. In neonates during the first 2 weeks of life, this dosage should be administered only every 72 h. In weeks 2-4 of life, the same dose should be given every 48 h, following which daily dosing is appropriate. This posology is derived from the age-related pharmacokinetics of fluconazole, with a higher volume of distribution and a prolonged plasma elimination half-life, especially during the first month of life. Drug monitoring during treatment should be performed to ensure therapeutic plasma concentrations of fluconazole within a range between 4 and 20 micrograms ml-1. The benefit of fluconazole should be investigated in prospective studies for treatment of systemic candidosis with administration of higher dosages as well as for early empiric therapy in VLBWIs.

Abstract
Hematogenous candidiasis is a life-threatening infection that occurs in critically ill patients. The incidence has increased dramatically over the past decade and Candida species are currently the fourth most common organism recovered from blood cultures in hospitalized patients. Numerous risk factors have been identified that predispose a patient to the development of hematogenous candidiasis. Diagnosis is often difficult in the clinical setting. Pharmacologic options for the management of hematogenous candidiasis includes amphotericin B, fluconazole, and flucytosine. Evidence from clinical trials indicate that fluconazole is as effective and better tolerated than amphotericin B for the management of hematogenous candidiasis in critically ill patients.
