Abstract
OBJECTIVE To assess the efficacy and safety of bladder irrigation with amphotericin B for treatment of fungal infection in the urinary tract. METHODS All the available randomized controlled trials (published before March, 2018) examining bladder irrigation with amphotericin B for treatment of urinary tract fungal infection were searched in the Cochrane Central Register of Controlled Trials (Issue 12, 2017), PubMed, EMBase, Web of Knowledge Database, CNKI, CBM, Wanfang DATA and VIP information. Data were extracted from the selected trials for meta-analysis using RevMan 5.3 software. RESULTS A total of 96 studies were retrieved from the databases, and 9 trials involving 853 patients were included in the analysis. Meta-analysis results showed that compared with oral administration of fluconazole, bladder irrigation with amphotericin B was more effective in the treatment of fungal infection in the urinary tract (OR=1.66, 95%CI: 1.2-2.3, P=0.002) and was associated with less adverse reactions. CONCLUSION Bladder irrigation with amphotericin B can improve the curative effect of fungal infection in the urinary tract, but due to the small sample size of the included studies, this conclusion needs to be further validated by high-quality studies.

Candiduria: Evidence-based approach to management, are we there yet? J Mycol Med 2017; 27:293-302.

Abstract
Candiduria is considered one of the most controversial issues in patient management. Neither the diagnosis nor the optimal treatment options are standardized. This is further complicated by lack of defined laboratory criteria for diagnosis as most of the studies were set for bacterial rather than fungal urinary tract infection (UTI). Furthermore, since Candida species is a known commensal of the genitourinary tract its presence in the urine sample adds ambiguity to making a definitive diagnosis of candidal UTI. Guidelines for diagnosis and management of candiduria have changed considerably over the past decades. In 1960s, the condition was believed to be benign with no intervention required. However, over the years new dimensions were added to address the issues associated with candiduria until the latest Infectious Diseases Association of America (IDSA) guidelines were published in 2009, which indicated that there was an increase in the incidence of candiduria caused by more resistant non-Candida albicans species. Further complicating the issue is the observation that candiduria may be the only indicator of a more serious invasive candidiasis, especially in immunocompromised patients. Long-term urinary catheterization is considered to be the most significant risk factor for candiduria followed by antibiotic use and diabetes. Strategies for management are based on the evaluation of candiduria in the context of the clinical setting to determine its relevance and make an appropriate decision about the need for antifungal therapy. Fluconazole is the main drug used for its efficacy and least complications. Other options include bladder irrigation with amphotericin B, flucytosine or parenteral amphotericin B. Since azoles other than fluconazole and all echinocandins are poorly excreted in urine they have been found to be less effective in candiduric patients.

Abstract
Background: Funguria occurs often in hospitalized patients and is most commonly caused by Candida species. Fluconazole is the agent of choice for most Candida urinary tract infections. Amphotericin B bladder irrigations (ABBI) are an alternative treatment option. Objective: The purpose of this study is to assess the efficacy of ABBI compared to fluconazole for the treatment of candiduria in the intensive care unit (ICU) setting. Methods: We conducted a retrospective chart review of patients admitted to ICUs at our institution with a positive urine culture for Candida species between 2005 and 2012. All patients receiving ABBI were included; patients receiving fluconazole for treatment of candiduria were matched by year. The primary endpoint was achievement of cure. Results: There was no difference in cure between the ABBI and fluconazole groups (59.6% vs. 52.8%, p = 0.55). Clearance was higher in patients receiving ABBI (92.3% vs. 67.9%, p < 0.001). Logistic regression found that renal dysfunction predicted greater cure with ABBI therapy compared to fluconazole (OR 7.63, 95% CI 1.81-32.1). Conclusion: ABBI was equally efficacious in achieving overall cure, and resulted in greater clearance of candiduria compared to fluconazole. ABBI may be considered an alternative to fluconazole for the treatment of candiduria and may be preferred over fluconazole in patients with renal dysfunction.

Abstract
It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.

Abstract
Candiduria is a nonspecific finding that occurs with contamination of a urine sample, colonization of an indwelling catheter and/or the bladder, symptomatic cystitis and invasive upper tract infection. Most patients are colonized and do not require antifungal therapy. Removing predisposing factors, such as indwelling catheters and antibiotics, will clear candiduria in almost 50% of asymptomatic patients. For patients with symptomatic Candida urinary tract infections, a variety of treatment options are available. Fluconazole is the antifungal agent of choice, achieving high urine concentrations with the oral formulation. Rarely, amphotericin B or flucytosine are used. Newer azole agents and echinocandins are not recommended for the treatment of urinary tract infections since they fail to achieve adequate urine concentrations.

Abstract
In many instances a report from the clinical laboratory indicating candiduria represents colonization or procurement contamination of the specimen and not invasive candidiasis. Even if infection of the urinary tract by Candida species can be confirmed, antifungal therapy is not always warranted. Further investigation may reveal predisposing factors, which if corrected or treated, result in the resolution of the infection. For those with symptomatic urinary tract infections (UTIs), the choice of antifungal agent will depend upon the clinical status of the patient, the site of infection, and the pharmacokinetics and pharmacodynamics of the agent. Because of its safety, achievement of high concentrations in the urine, and availability in both an oral and intravenous formulation, fluconazole is preferred for the treatment of Candida UTIs. Flucytosine is concentrated in urine and has broad activity against Candida spp, but its use requires caution because of toxicity. Low-dose amphotericin B may be useful for Candida UTIs in selected patients. The role of echinocandins and azoles that do not achieve measurable concentrations in the urine is not clear. Small case series note some success, but failures have also occurred. Irrigation of the bladder with antifungal agents has limited utility. However, with fungus balls, irrigation of the renal pelvis through a nephrostomy tube can be useful in combination with systemic antifungal agents.

Abstract
BACKGROUND Complicated urinary tract infection occurs in individuals with functional or structural abnormalities of the genitourinary tract. OBJECTIVE To review current knowledge relevant to complicated urinary tract infection, and to provide evidence-based recommendations for management. METHODS The literature was reviewed through a PubMed search, and additional articles were identified by journal reference review. A draft guideline was prepared and critically reviewed by members of the Association of Medical Microbiology and Infectious Disease Canada Guidelines Committee, with modifications incorporated following the review. RESULTS Many urological abnormalities may be associated with complicated urinary infection. There is a wide spectrum of potential infecting organisms, and isolated bacteria tend to be more resistant to antimicrobial therapy. Morbidity and infection outcomes in subjects with complicated urinary infection are principally determined by the underlying abnormality rather than the infection. Principles of management include uniform collection of a urine specimen for culture before antimicrobial therapy, characterization of the underlying genitourinary abnormality, and nontreatment of asymptomatic bacteriuria except before an invasive genitourinary procedure. The antimicrobial regimen is determined by clinical presentation, patient tolerance, renal function and known or anticipated infecting organisms. If the underlying abnormality contributing to the urinary infection cannot be corrected, then early post-treatment recurrence of infection is anticipated. CONCLUSIONS The management of complicated urinary infection is individualized depending on patient variables and the infecting organism. Further clinical investigations are necessary to assist in determining optimal antimicrobial regimens.

Abstract
The introduction of several new antifungals has significantly expanded both prophylaxis and treatment options for invasive fungal infections (IFIs). Relative to amphotericin B deoxycholate, lipid-based formulations of amphotericin B have significantly reduced the incidence of nephrotoxicity, but at a significant increase in drug acquisition cost. Newer, broad-spectrum triazoles (notably voriconazole and posaconazole) have added significantly to both the prevention and treatment of IFIs, most notably Aspergillus spp. (with voriconazole) and the treatment of some emerging fungal pathogens. Finally, a new class of parenteral antifungals, the echinocandins, is employed most frequently against invasive candidal infections. While the role of these newer agents continues to evolve, this review summarizes the activity, safety and clinical applications of agents most commonly employed in the treatment of IFIs.

Abstract
The prevalence of candiduria has increased in patients admitted to intensive care units (ICUs) and it has emerged as a common nosocomial infection among critically ill patients. Generally, urinary candidiasis should be regarded as a risk factor for invasive candidiasis, but not as a disease that needs to be treated on its own. However, decision-making in critically ill patients with candiduria may become a balancing act, because candiduria may be the only indication for invasive candidaemia with significant morbidity and mortality. Of further concern, there is a worldwide increase in the incidence of non-albicans spp. isolated from urine with highly variable susceptibility to fluconazole, which has been the first-line therapy for Candida infections during the last decades. This article discusses everyday problems with urinary candidiasis in interdisciplinary ICUs.

Abstract
Urinary tract infections (UTIs) are a common burden in patients with diabetes mellitus. Cystitis, ascending infections leading to pyelonephritis, emphysematous complications and renal and perinephric abscesses are well recognised in this group of patients especially if glycaemic control is poor. Despite the clinical significance of UTI in diabetes, it is inadequately understood and management regimens are mostly not evidence based. Anticipation of potential complications and earlier interventions are vital to reduce serious adverse outcomes. Herein we discuss the aetiology, pathogenesis and management of UTI and its local and more remote complications.

Abstract
PURPOSE OF REVIEW To review the literature on the role of fungi in chronic rhinosinusitis (CRS) pathogenesis and the effect of antifungal drug therapy and antifungal immunotherapy. RECENT FINDINGS This paper reviews the most recent articles investigating the role of fungi in CRS pathogenesis. In addition to possible aberrant innate and adaptive antifungal immune responses and fungus antihost effects, which all may explain disease development, the effect of antifungal drug therapy and antifungal immunotherapy is reviewed. SUMMARY Although fungi can be detected in the nose and paranasal sinuses of nearly all patients with CRS and are present in almost all healthy controls, various studies suggest that there may be mechanisms by which fungi exert an effect on sinus mucosa in susceptible individuals only. Future studies will have to clarify the role of fungi in CRS, which fungal organisms, if at all, may be pathogenic and what exactly characterizes the immunological response to fungi that potentially results in the development of disease. Presently, in the absence of convincing immunological data and evidence for clinical improvement of CRS upon therapy with antifungal agents, the case against the fungus remains unproven.

Abstract
The role of fungi in chronic rhinosinusitis (CRS) is not clear. Fungi can be detected in the nose and paranasal sinuses of virtually all CRS patients; however, they also appear to be present in healthy controls. Various theories attempt to explain the mechanisms by which fungi can exert an effect on sinus mucosa in susceptible individuals. Further studies are necessary to clarify the role of fungi in CRS, which fungal organisms (if any) are pathogenic, and what exactly characterizes the immunologic response to fungi that may result in the development of disease. However, in the absence of convincing immunologic data and evidence of clinical improvement of CRS after antifungal therapy, the case against the fungus remains unproven.

Abstract
BACKGROUND It has been suggested that an exaggerated immune response to fungi is crucial in the pathogenesis of chronic rhinosinusitis (CRS). Based on this rationale, the use of topical antifungals (amphotericin B) has been advocated. Studies on its clinical effectiveness are, however, contradictory. OBJECTIVES To examine the effect of nasal antifungal treatment on secreted mediators in samples of nasal lavage fluid from patients with CRS with or without nasal polyps (NP). METHODS Part two of a prospective double-blind, placebo-controlled multicenter clinical trial investigating the effect of 13 weeks of treatment with amphotericin B or placebo on the levels of pro-inflammatory cytokines, chemokines and growth factors (i.e., IL-1beta, IL-1RA, IL-2, IL-2R, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12 (p40/p70 subunits), IL-13, IL-15, IL-17, TNF-alpha, IFN-alpha, IFN-gamma, G-CSF, GM-CSF, MIP-1alpha, MIP-1beta, IP-10, MIG, eotaxin, RANTES, MCP-1, MCP-2, MCP-3, VEGF, EGF, FGF-basic, HGF, Gro-alpha) and albumin via a fluorescent enzyme immunoassay in nasal lavage specimens of CRS patients with or without NP. RESULTS Topical amphotericin B had no significant effect on the level of any of the tested pro-inflammatory cytokines, chemokines, and growth factors in CRS nasal lavage samples. Treatment with placebo, however, increased the level of MIP-1alpha and MIP-1beta, which are mediators involved in wound healing. CONCLUSIONS Topical amphotericin B has no significant effect on activation markers of nasal inflammatory cells in chronic rhinosinusitis with or without nasal polyps.

Abstract
Chronic rhinosinusitis (CRS) is an inflammatory disorder affecting the nose and paranasal sinuses. Although bacteria have long been implicated as pathogens in most forms of CRS, fungi may be responsible for some forms. Several recent studies demonstrated that, under optimal conditions, fungi can be identified in the nose and paranasal sinuses of nearly every individual (including all CRS patients). An aberrant immune response to these ubiquitous fungi has been suggested to explain the development of CRS in some individuals. Several mechanisms requiring additional research, including adequate controls, have been proposed and are reviewed in this article. Although preliminary trials suggested that CRS signs and symptoms improve upon treatment with topical and oral antifungal agents, several double-blind, placebo-controlled trials demonstrated the contrary. In the absence of convincing immunologic data and evidence of clinical improvement upon therapy with antifungal agents, the case against fungi remains unproven.

Abstract
Candiduria remains a controversial issue for clinicians once that it may represent a broad variety of possibilities including colonization, local or systemic infection. We will discuss the epidemiology, diagnosis and treatment of candiduria in different settings of patients, including renal transplant recipients. Definitions on therapy are mostly based on epidemiological and clinical data. Once antifungal therapy is required the following antifungal treatment may be used: intravenous amphotericin B, bladder irrigation with amphotericin B or fluconazole. Blood cultures may be required in patients with candiduria and high risk for developing hematogenous infection. Removal of the urinary catheter must be considered in order to avoid persistent candiduria and recurrence.

Abstract
Thirty-five animals (23 dogs, 12 cats) with fungal urinary tract infections (UTIs) were retrospectively studied. Dysuria, hematuria, increased frequency of micturition, anorexia, depression, and pyrexia were the most common clinical signs noted. Seven species of fungi were identified in the affected animals. Candida albicans was the most common isolate. Most animals diagnosed with fungal UTI also had other concurrent urinary tract or medical problems. Lower urinary tract diseases, diabetes mellitus, neoplasia, and renal failure were the most common concurrent or preceding diseases identified. Resolution of fungal UTI occurred in 12 animals that received specific antifungal treatment.

Abstract
JUSTIFICATION Candiduria is increasingly frequent among patients admitted to intensive care units but its significance remains unclear. OBJECTIVES Search for eventual correlation between quantitative candiduria and known risk factors for invasive candidiasis. STUDY DESIGN Prospective. PATIENTS AND METHODS A four-month study was conducted in 162 patients hospitalized in the intensive care unit for more than 72 hours. All patients underwent a weekly research of candiduria added to sampling from different body sites to determine the Pittet Candida colonization index. RESULTS Candiduria has been proved in 56 cases (34%). It was superior or equal to 10(4) UFC/ml among 28 patients (50%). Candida tropicalis, Candida glabrata and Candida albicans has been isolated in 41, 22 and 20% respectively. All patients had at least one major and two minor risk factors for Candida infection. Six patients (10%) developed invasive candidiasis. The global mortality rate was at 52%. Pittet colonization index was significantly different between patients with candiduria and those with invasive candidiasis (p=0.01). There was a statistically significant correlation between candiduria superior or equal to 10(4) UFC/ml and Pittet colonization index superior or equal to 0.5 (p=0.01). CONCLUSION Candiduria superior or equal to 10(4) UFC/ml associated with risk factors may predict invasive candidiasis in critically ill patients.

Abstract
OBJECTIVES To evaluate in an in vitro study the irrigation and drainage capabilities of a variety of available catheters. Three-way Foley catheters are used when irrigation of the bladder is anticipated to prevent or manage blood clots in the bladder. METHODS Six operators applied maximal one-handed pressure irrigation with a catheter-tip syringe through the irrigation and drainage ports of the Bardex and Dover three-way catheters (16F to 26F). Maximal manual irrigation flow was recorded using a flowmeter. Continuous gravity irrigation and drainage flows were measured by suspending a 2-L irrigation bag 80 cm above the catheters and fastening an artificial bladder to the drainage tip of each Foley catheter with the catheter balloon inflated to 30 mL. RESULTS The Bardex 22F and 24F catheters had superior manual irrigation using the irrigation port (maximal urinary flow rate 8.9 +/- 1.3 mL/s and 9.5 +/- 1.5 mL/s, respectively, P < 0.000001) compared with the Dover 22F and 24F catheters. The Bardex and Dover 22F catheters (maximal urinary flow rate 29.0 +/- 1.9 mL/s and 29.3 +/- 1.9 mL/s, respectively, P = 0.66) and 24F catheters (maximal urinary flow rate 30.5 +/- 2.0 mL/s and 30.6 +/- 1.2 mL/s, respectively, P = 0.83) performed equally in manual irrigation using the drainage port. The Bardex 22F (average flow rate 1.6 +/- 0.1 mL/s, P < 0.00001) and 24F (average flow rate 1.7 +/- 0.0 mL/s, P < 0.000001) catheters exhibited better continuous irrigation and flow than the Dover 22F and 24F catheters. CONCLUSIONS Three-way catheters are placed in situations in which efficient bladder irrigation is essential for patient safety. The Bardex 22F to 26F catheters optimized continuous bladder irrigation of the catheters tested.

Abstract
Candiduria is a common finding. Yeasts can be detected in urine that is contaminated during collection, in patients who have bladder colonization, and in patients who have upper urinary tract infection that developed either from retrograde spread from the bladder or hematogenous spread from a distant source. Most patients with candiduria are asymptomatic. The rate of development of complications is not known but appears to be low; candidemia rarely results from asymptomatic candiduria unless obstruction is present or instrumentation of the urinary tract is done. Unfortunately, there are no established diagnostic tests that reliably distinguish infection from colonization. Guidelines for the treatment of candiduria, based almost entirely on anecdotal reports and expert opinions, rather than controlled clinical trials, have been suggested by the Infectious Diseases Society of America. Until reliable methods to distinguish infection from colonization are developed, further treatment trials are unlikely to provide information to guide the clinician in the treatment of candiduria.

Abstract
In this article, we review the issues surrounding funguria and its management. With this background, the value of bladder irrigation with amphotericin B for the management of funguria is directly examined. Amphotericin B bladder irrigation is used frequently in clinical practice. Although its use is not standardized, there are multiple studies that attempt to show the impact on funguria management. These bladder irrigations have been used either for treatment of funguria or (less commonly) as a diagnostic test in attempts to identify upper urinary tract disease. Despite their widespread therapeutic use and relative safety, it is not clear from our experience and a review of the literature that amphotericin B bladder irrigations have any diagnostic or therapeutic value. The patient may be best served by removal of the urinary catheter, if possible, rather than by instillation of bladder irrigation with amphotericin B.

Abstract
Administration of antifungals by routes other than that for which the agent was designed or approved have been utilised in attempts to provide directed therapy, reduce adverse effects and improve drug penetration into selected infection sites, such as the central nervous system, lungs and peritoneum. The most widely investigated agent utilising a novel method of drug delivery is amphotericin B. Dose forms for this agent include topicals (aerosol, nasal spray, irrigations, pastes, absorbable sponges, impregnated bone cement and gelatin), oral dosage forms (solutions, suspensions, tablets and so on) and ophthalmic preparations (drops, ointments and injections). Amphotericin B has been administered by routes such as oral, endobronchial, intrathecal, intracisternal, intra-articular, intraperitoneal, ophthalmic and as an antibiotic 'line lock'. Nystatin has been administered as an aerosol, percutaneous paste and bladder washes. Azoles, such as miconazole, fluconazole, ketoconazole and posaconazole, have been administered by novel methods but to a lesser degree. Most of these reports involve miconazole. The dose forms and routes of administration for azoles have included irrigants (bladder, joint), ophthalmic preparations (eye drops, intraocular injections, ointments), impregnated bone cement, endobronchial and intrathecal administration. Finally, both methylene blue (bladder washes) and flucytosine (peritoneal lavage, ophthalmic eye drops) have also been employed. Adequate evaluations of both the safety and efficacy of these therapies are most often hindered by prior or concomitant antifungal therapies, comorbidities and the lack of controlled clinical trials. In addition, the availability of newer treatment options, which demonstrate significant improvement in drug distribution and treatment-related adverse effects make many such novel modes of administration less practical or necessary. In contrast, the inhalation of antifungal aerosols, such as amphotericin B, is rapidly becoming a viable prophylactic option.

Abstract
BACKGROUND To compare morbidity and mortality in inpatients with asymptomatic funguria between those treated and those observed for funguria. METHODS Retrospective analyses were performed in 149 consecutive adult tertiary care inpatients with asymptomatic funguria. The primary endpoints were death, length of hospitalisation and progression to invasive fungal infection (IFI). RESULTS Of the 149 subjects, 70% were female, 55% were >65 years, recent antibiotic and urinary catheter use occurred in >70%, diabetes in 32%, recent ICU admission in 29%, and concomitant bacteriuria in 28%. Forty-seven percent did not receive active intervention. Of the remainder, 46% were managed by controlling or eliminating risk factors for funguria or progression to IFI; fluconazole or amphotericin B were used to treat the other 54%. Fourteen percent died and 2.7 % progressed to IFI, with no significant difference between the treated versus observed groups for either endpoint (p>0.2). Median length of hospitalisation was significantly greater in the treated group (p<0.01); multivariate analysis demonstrated an exclusive relationship to the greater number of risk factors present in the treated group. CONCLUSION Asymptomatic funguric patients who were managed with risk reduction and/or antifungal therapy were older, had more risk factors for funguria and subsequent progression to IFI, and had a longer hospital admission than those managed with observation. Treatment of asymptomatic funguria with risk reduction and/or antifungal therapy did not impact adult inpatient morbidity or mortality in this review; rather, the presence of multiple risk factors for funguria or IFI appeared to serve as a 'sickness indicator'. SUMMARY In this study, we found that treatment for asymptomatic funguria in hospitalised adults did not impact morbidity or mortality. Rather, the presence of multiple risk factors for funguria or IFI correlated with a longer duration of hospitalisation, suggesting that funguria may be a 'sickness indicator', similar to bacteriuria in the elderly.

Abstract
Studies in experimental animals and humans have shown that Amphotericin B (AmB) persists in urine for days to weeks after a single IV dose in levels that should inhibit candidal organisms and thereby obviate the need for frequent dosing. Including data from four previously described patients, we have now treated a total of 11 patients (12 episodes) with Candida urinary tract infections with single-dose AmB (six, Candida albicans; two, C. tropicalis; four, other nonalbicans Candida). The duration of candiduria prior to entry ranged from 18 to 180 days. Predisposing conditions included renal transplantation (1), diabetes mellitus (8), genitourinary stones (1) or anomalies (4), catheterization (2), and antibacterial therapy (11). A single patient was intolerant of AmB. Out of 11 evaluable candiduric episodes, eight resolved. Failure occurred in one patient with a chronic indwelling bladder catheter and in the allograft recipient. The data suggest that the sustained urinary excretion of AmB may permit successful single- or paucidose therapy of Candida urinary tract infections in some patients with a minimum of toxicity.

Abstract
Urinary tract infection continues to be a major source of morbidity for surgical patients, and treating these infections continues to be a difficult problem in clinical surgical practice. The majority of these infections are due to urinary catheters. One strategy that has been advanced to prevent the morbidity associated with these infections is the use of silver-coated urinary catheters.

Abstract
Records from 20 animals (13 dogs, seven cats) with Candida spp. urinary tract infections were reviewed. Six Candida spp. were isolated; Candida albicans was the most common isolate. Concurrent diseases or nonantifungal drugs administered within 1 month of isolation included antibiotics (n=16), corticosteroids (n=6), diabetes mellitus (n=4), nonurogenital neoplasia (n=3), and noncandidal urogenital disease (n=14). All animals had sources of local or systemic immune compromise that likely predisposed to infection. Of five animals with resolution of infection, three did not receive specific antifungal treatment. The authors conclude that correction of predisposing conditions is likely critical for management of Candida spp. urinary tract infection.

Abstract
The most relevant information on the present state of the art of antifungal chemotherapy is reviewed in this chapter. For dermatomycoses a variety of topical antifungals are available, and safe and efficacious systemic treatment, especially with the fungicidal drug terbinafine, is possible. The duration of treatment can be drastically reduced. Substantial progress in the armamentarium of drugs for invasive fungal infections has been made, and a new class of antifungals, echinocandins, is now in clinical use. The following drugs in oral and/or intravenous formulations are available: the broad spectrum polyene amphotericin B with its new "clothes"; the sterol biosynthesis inhibitors fluconazole, itraconazole, and voriconazole; the glucan synthase inhibitor caspofungin; and the combination partner flucytosine. New therapy schedules have been studied; combination therapy has found a significant place in the treatment of severely compromised patients, and the field of prevention and empiric therapy is fast moving. Guidelines exist nowadays for the treatment of various fungal diseases and maintenance therapy. New approaches interfering with host defenses or pathogenicity of fungal cells are being investigated, and molecular biologists are looking for new targets studying the genomics of pathogenic fungi.

Abstract
The increasing trend of a multimodal therapeutic approach in gynecologic oncology in the last few years has markedly changed the nature, frequency, and clinical presentation of infectious diseases. Despite the improved diagnostic tools, refined surgical technique, and routine use of prophylactic antibiotics, the morbidity and mortality of infectious complications remain significant. The rational use of available treatment resources, the recognition of risk factors, and increased awareness of host-cancer interactions should reduce the incidence of these serious infectious complications. The improved prevention and more efficient treatment of infections in the gynecologic oncology patient will not only improve prognosis but also have a significant economic impact as well.

Abstract
Systemic fungal infections are an increasing problem in older adults. For several of the endemic mycoses, this increase is the result of increased travel and leisure activities in areas endemic for these fungi. Immunosuppressive agents, care in an intensive care unit, and invasive devices all contribute to infection with opportunistic fungi. Treatment of systemic fungal infections is usually with an azole or amphotericin B. The preferred regimen depends on the specific fungal infection, the site and the severity of the infection, the state of immunosuppression of the patient and the possible toxicities of each drug for a specific patient. In older adults, drug-drug interactions between the azoles and drugs commonly prescribed for older persons may lead to serious toxicity, and absorption of itraconazole can be problematic. Amphotericin B is associated with significant nephrotoxicity, especially in older adults with pre-existing renal disease, and infusion-related adverse effects. Newer lipid formulations of amphotericin B can obviate some of these toxicities, but their role in the treatment of systemic fungal infections in older adults has not yet been clarified.

Abstract
Complicated urinary tract infection occurs in the setting of a functionally or structurally abnormal genitourinary tract. Many different abnormalities may lead to a designation of complicated urinary tract infection, and these abnormalities will have different influences on the frequency of infection and likelihood of relapse or reinfection. The microbiology of complicated urinary tract infection is characterised by a greater variety of organisms and increased likelihood of antimicrobial resistance compared with acute uncomplicated urinary tract infection. Appropriate management requires a urine specimen for culture prior to institution of antimicrobial therapy, and ensuring that the underlying abnormality is fully characterised to determine whether it can be corrected. A wide variety of antimicrobial agents are effective for treatment, and are usually given for 7 to 14 days. If the underlying abnormality can be corrected, subsequent infections may be prevented. However, if the underlying abnormality cannot be corrected a high recurrence rate of infection, approaching 50% by 4 to 6 weeks, is expected. Further study of complicated urinary tract infection is necessary, including determination of when asymptomatic bacteriuria warrants treatment, and exploration of nonantimicrobial approaches to management.

Abstract
The distinction between Candida colonization of the urinary tract and infection is often blurred. Asymptomatic candiduria is particularly common in catheterized intensive care unit patients. To date, few studies have addressed the appropriate treatment regimens for candiduria. Fluconazole has become a mainstay of therapy; however, when to treat, whom to treat, and how long to treat are still largely unanswered questions. Asymptomatic nosocomial candiduria infrequently requires treatment intervention because morbidity is low and ascending infection and candidemia are rare complications. An understanding of the anatomic site of infection drives treatment decisions. More research is needed to define diagnostic criteria and therapeutic pathways. This review attempts to summarize the diagnosis and management of candiduria.

Abstract
Fungal infections of the urinary tract, especially those caused by Candida species, are becoming increasingly common. Often the line between Candida colonization and infection is blurred. Diagnosis typically depends on the discovery of pyuria with high colony Candida counts in the urine. To date, there have been few studies to have addressed treatment regimens for patients with candiduria. Fluconazole has become a mainstay of therapy; however, questions regarding when to treat, whom to treat, and how long to treat are still largely unanswered. Asymptomatic nosocomial candiduria does not frequently require treatment intervention, because morbidity is low and ascending infection and candidemia are rare complications. Treatment decisions are driven by an understanding of the anatomic site of infection. For Candida cystitis, the first-line treatment is fluconazole, given orally. Ascending pyelonephritis usually requires the administration of a systemic antifungal agent and often requires correction of the obstruction or surgical drainage. More research is needed to define diagnostic criteria and therapeutic pathways. This review will attempt to summarize the state of the art of diagnosis and management of candiduria.

Abstract
Candida spp. are increasingly involved in nosocomial infections in severely ill patients and the diagnosis is difficult. In this context, the significance of candiduria remains unclear. Management of this condition is still equivocal, because of the lack of information about its natural history and its predictive value for disseminated infection. Little is known about the discriminant value of colony count. After a comprehensive review of the available published data, the preliminary results of a multicentric prospective survey in critically ill patients hospitalised in intensive care units are given. The aim of the study was to search for correlations between quantitative candiduria and known risk factors for disseminated candidiasis. There is a statistically significant correlation (p = 0.003) between heavy candiduria (> 10(4) cfu.mL-1) and high Pittet colonisation index (> or = 0.5). Quantification of candiduria could be useful to select patients at high risk for disseminated candidiasis.

Abstract
OBJECTIVE To identify the most appropriate dose of fluconazole for the treatment of symptomatic fungal urinary tract infection (UTI). DATA SOURCES Primary literature identified through MEDLINE (1990-June 2000). Key search terms included fluconazole and urinary tract infection. DATA SYNTHESIS Fluconazole is approved for the treatment of candidal UTIs, but dosage recommendations are not consistent. An evaluation of clinical studies of fluconazole for the treatment of candidal UTI was performed. CONCLUSIONS Questions remain about the optimal dosing of fluconazole, including the most appropriate dose in non-albicans species of candida as well as the optimal duration of therapy. Until further studies are performed, a fluconazole 200-mg loading dose followed by 100 mg/d for at least four days appears to be the most appropriate dose for the treatment of symptomatic candidal UTI in patients without systemic fungal infection or severe renal failure.

Abstract
The clinical finding of candiduria is often an enigmatic problem for the evaluating physician. The significance of yeast in the urine can range from procurement contamination to a sign of a life-threatening, opportunistic fungal infection. Proper evaluation requires validation of funguria, consideration of the setting in which it occurs, and the status of the patient. Provided that the patient is clinically stable, asymptomatic candiduria usually need not be treated with an antifungal agent. Rather, management should be directed at the elimination of predisposing factors, if feasible. When treatment is required, appropriate agents include amphotericin B (AmB), various lipid preparations of AmB (L-AmB), azoles, and flucytosine. Parenteral AmB is most useful against life-threatening infections in which the urinary tract is but one component of a widespread infection, or when resistant Candida are causative. Shorter courses of therapy may be preferable in certain cases. L-AmB treatment has been less sucessful. Intravesical AmB is a time-honored approach, but is best employed diagnostically rather than therapeutically. Fluconazole is presently the agent of first choice for susceptible fungi, but dosage and duration of therapy have not been established. Flucytosine is a useful alternative, especially for resistant Candida, but its toxicity must be closely monitored.

Abstract
Fluconazole is currently a first-line agent used for therapy of non-critically ill patients with candidal infection. Its efficacy, the availability of an oral formula, and its relatively low toxicity make it a very attractive drug for use in many clinical situations. The advisability of prophylaxis and empirical treatment in transplant patients is a difficult issue for the following reasons: the potential emergence of resistance to the azoles, the lack of solid data establishing its advantage over placebo and/or oral nonabsorbable antifungal agents in some of the clinical conditions encountered, its ineffectiveness against molds, and its cost. Judicious use of fluconazole where its efficacy has been well established would provide the best therapy for patients and would limit the emergence of potential pathogens. As new antifungal agents are approved for clinical use, appropriate clinical trials will need to be designed and conducted in order for clinicians to make rational decisions in selecting the most appropriate drug for the specific indication. Prophylaxis and treatment with fluconazole in various transplant situations is reviewed.

Abstract
The incidence of fungal infections continues to rise as the population of immunocompromised individuals increases. Despite the enlarging numbers of infections, there are only a few antifungal agents for treatment of deep-seated, invasive infections. These agents include amphotericin B, flucytosine, terbinafine, and several azoles. Progress has been made in understanding the role of these agents in a variety of infections and this article examines in detail these agents and their prophylactic, empiric, and therapeutic uses in invasive mycoses. This article focuses on general concepts of antifungal therapies and provides a detailed review of each antifungal agent available for treatment of deep-seated mycoses.

Abstract
Infections due to Candida species are the most common of the fungal infections. Candida species produce a broad range of infections, ranging from nonlife-threatening mucocutaneous illnesses to invasive process that may involve virtually any organ. Such a broad range of infections requires an equally broad range of diagnostic and therapeutic strategies. This document summarizes current knowledge about treatment of multiple forms of candidiasis and is the guideline of the Infectious Diseases Society of America (IDSA) for the treatment of candidiasis. Throughout this document, treatment recommendations are scored according to the standard scoring scheme used in other IDSA guidelines to illustrate the strength of the underlying data. The document covers 4 major topical areas. The role of the microbiology laboratory. To a greater extent than for other fungi, treatment of candidiasis can now be guided by in vitro susceptibility testing. The guidelines review the available information supporting current testing procedures and interpretive breakpoints and place these data into clinical context. Susceptibility testing is most helpful in dealing with infection due to non-albicans species of Candida. In this setting, especially if the patient has been treated previously with an azole antifungal agent, the possibility of microbiological resistance must be considered. Treatment of invasive candidiasis. In addition to acute hematogenous candidiasis, the guidelines review strategies for treatment of 15 other forms of invasive candidiasis. Extensive data from randomized trials are really available only for therapy of acute hematogenous candidiasis in the nonneutropenic adult. Choice of therapy for other forms of candidiasis is based on case series and anecdotal reports. In general, both amphotericin B and the azoles have a role to play in treatment. Choice of therapy is guided by weighing the greater activity of amphotericin B for some non-albicans species (e.g., Candida krusei) against the lesser toxicity and ease of administration of the azole antifungal agents. Flucytosine has activity against many isolates of Candida but is not often used. Treatment of mucocutaneous candidiasis. Therapy for mucosal infections is dominated by the azole antifungal agents. These drugs may be used topically or systemically and have been proven safe and efficacious. A significant problem with mucosal disease is the propensity for a small proportion of patients to suffer repeated relapses. In some situations, the explanation for such a relapse is obvious (e.g., relapsing oropharyngeal candidiasis in an individual with advanced and uncontrolled HIV infection), but in other patients the cause is cryptic (e.g., relapsing vaginitis in a healthy woman). Rational strategies for these situations are discussed in the guidelines and must consider the possibility of induction of resistance over time. Prevention of invasive candidiasis. Prophylactic strategies are useful if the risk of a target disease is sharply elevated in a readily identified group of patients. Selected patient groups undergoing therapy that produces prolonged neutropenia (e.g., some bone-marrow transplant recipients) or who receive a solid-organ transplant (e.g., some liver transplant recipients) have a sufficient risk of invasive candidiasis to warrant prophylaxis.

Abstract
Although fungal urinary tract infections are an increasing nosocomial problem, the significance of funguria is still not clear. This multicenter prospective surveillance study of 861 patients was undertaken to define the epidemiology, management, and outcomes of funguria. Diabetes mellitus was present in 39% of patients, urinary tract abnormalities in 37.7%, and malignancy in 22.2%; only 10.9% had no underlying illnesses. Concomitant nonfungal infections were present in 85%, 90% had received antimicrobial agents, and 83.2% had urinary tract drainage devices. Candida albicans was found in 51.8% of patients and Candida glabrata in 15.6%. Microbiological and clinical outcomes were documented for 530 (61.6%) of the 861 patients. No specific therapy for funguria was given to 155 patients, and the yeast cleared from the urine of 117 (75.5%) of them. Of the 116 patients who had a catheter removed as the only treatment, the funguria cleared in 41 (35.3%). Antifungal therapy was given to 259 patients, eradicating funguria in 130 (50.2%). The rate of eradication with fluconazole was 45.5%, and with amphotericin B bladder irrigation it was 54.4%. Only 7 patients (1.3%) had documented candidemia. The mortality rate was 19.8%, reflecting the multiple serious underlying illnesses found in these patients with funguria.

Abstract
Management of candiduria is limited by the lack of information about its natural history and lack of data from controlled studies on the efficacy of treating it with antimycotic agents. We compared fungal eradication rates among 316 consecutive candiduric (asymptomatic or minimally symptomatic) hospitalized patients treated with fluconazole (200 mg) or placebo daily for 14 days. In an intent-to-treat analysis, candiduria cleared by day 14 in 79 (50%) of 159 receiving fluconazole and 46 (29%) of 157 receiving placebo (P<.001), with higher eradication rates among patients completing 14 days of therapy (P<.0001), including 33 (52%) of 64 catheterized and 42 (78%) of 54 noncatheterized patients. Pretreatment serum creatinine levels were inversely related to candiduria eradication. Fluconazole initially produced high eradication rates, but cultures at 2 weeks revealed similar candiduria rates among treated and untreated patients. Oral fluconazole was safe and effective for short-term eradication of candiduria, especially following catheter removal. Long-term eradication rates were disappointing and not associated with clinical benefit.
