Abstract
OBJECTIVES Clinical presentation and outcomes of esophageal candidiasis (EC) in cancer patients are scarcely studied in the azole era, as is the correlation between clinical, endoscopic, and histopathological EC manifestations. METHODS We retrospectively reviewed the risk factors, clinical features, and outcomes of pathology-documented EC cases at MD Anderson Cancer Center. We further assessed associations between presence of symptoms, standardized 4-stage endoscopic grade (Kodsi classification), histopathological data, and fluconazole treatment failure. RESULTS Among 323 cancer patients with EC, 89% had solid tumors, most commonly esophageal cancer (29%). Thirty-three percent of EC patients were asymptomatic. The proportion of symptomatic EC patients significantly increased with endoscopic grade (P = 0.005). Among 202 patients receiving oral fluconazole, 27 (13%) had treatment failure. Underlying esophageal disease was the only independent predictor of fluconazole treatment failure (odds ratio: 3.88, P = 0.005). Endoscopic grade correlated significantly with Candida organism burden (Correlation coefficient [ρ] = 0.21, P < 0.01) and neutrophilic inflammation (ρ = 0.18, P < 0.01). Candida invasion of the squamous mucosal layer was associated with treatment failure (P = 0.049). CONCLUSIONS EC was predominantly encountered in patients with solid tumors. One-third of EC patients were asymptomatic, challenging traditional symptom-based diagnosis. The development of integrated clinicopathological scoring systems could further guide the therapeutic management of cancer patients with EC.

Abstract
Background Invasive fungal disease caused by dimorphic fungi is associated with significant morbidity and mortality. Super-bioavailability itraconazole (SUBA-itra) is a novel antifungal agent with pharmacokinetic advantages over currently available formulations. In this prospective comparative study, we report the outcomes of patients with endemic fungal infections (histoplasmosis, blastomycosis, coccidioidomycosis, and sporotrichosis). Methods This open-label randomized trial evaluated the efficacy, safety, and pharmacokinetics SUBA-itra compared with conventional itraconazole (c-itra) treatment for endemic fungal infections. An independent data review committee determined responses on treatment days 42 and 180. Results Eighty-eight patients were enrolled for IFD (SUBA-itra, n = 42; c-itra, n = 46) caused by Histoplasma (n = 51), Blastomyces (n = 18), Coccidioides (n = 13), or Sporothrix (n = 6). On day 42, clinical success was observed with SUBA-itra and c-itra on day 42 (in 69% and 67%, respectively, and on day 180 (in 60% and 65%). Patients treated with SUBA-itra exhibited less drug-level variability at days 7 (P = .03) and 14 (P = .06) of randomized treatment. The concentrations of itraconazole and hydroxyitraconazole were comparable between the 2 medications (P = .77 and P = .80, respectively). There was a trend for fewer adverse events (AEs; 74% vs 87%, respectively; P = .18) and serious AEs (10% vs 26%; P = .06) in the SUBA-itra-treated patients than in those receiving c-itra. Serious treatment-emergent AEs were less common in SUBA-itra-treated patients (12% vs 50%, respectively; P < .001). Conclusions SUBA-itra was bioequivalent, well tolerated, and efficacious in treating endemic fungi, with a more favorable safety profile than c-itra. Clinical Trials Registration NCT03572049.

Abstract
Infectious esophagitis is a leading cause of esophagitis worldwide. While esophageal infections have traditionally been associated with immunocompromised patients, these disorders are becoming increasingly recognized in immunocompetent individuals. The three most common etiologies of infectious esophagitis are Candida, herpes simplex virus, and cytomegalovirus. Human papilloma virus infection can also involve the esophagus in the form of ulcerative lesions and papillomas. Less common etiologies include various other fungal, bacterial, and viral organisms. This review provides a comprehensive update on risk factors, diagnosis, and management of both common and less common infections of the esophagus.

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
Esophageal candidiasis is a frequent cause of morbidity in immunocompromised patients. Isavuconazole is a novel, broad-spectrum antifungal developed for the treatment of opportunistic fungal infections. This phase 2 trial compared the efficacy and safety of three oral dosing regimens of isavuconazole with an oral fluconazole regimen in the primary treatment of uncomplicated esophageal candidiasis. The isavuconazole regimens were as follows: 200 mg on day 1 and then 50 mg once daily (arm A), 400 mg on day 1 and then 400 mg once-weekly (arm B), and 400 mg on day 1 and then 100 mg once daily (arm C). Patients in arm D received fluconazole at 200 mg on day 1 and then 100 mg once daily. The minimum treatment duration was 14 days. The primary endpoint was the rate of endoscopically confirmed clinical response at end of therapy. Safety and tolerability were also assessed. Efficacy was evaluated in 153 of 160 enrolled patients. Overall, 146 (95.4%) achieved endoscopically confirmed clinical success. Each of the isavuconazole regimens was shown to be not inferior to fluconazole, i.e., arm A versus D, -0.5% (95% confidence interval [CI] -10.0 to 9.4), arm B versus D, 3.5% (95% CI, -5.6 to 12.7), and arm C versus D, -0.2% (95% CI, -9.8 to 9.4). The frequency of adverse events was similar in arm A (n = 22; 55%), arm B (n = 18; 45%), and arm D (n = 22; 58%), but higher in arm C (n = 29; 71%). In summary, efficacy and safety of once-daily and once-weekly isavuconazole were comparable with once-daily fluconazole in the primary treatment of uncomplicated esophageal candidiasis.

Abstract
Mucosal candidiasis is frequent in immunocompromised HIV-infected highly active antiretroviral (HAART) naive patients or those who have failed therapy. Mucosal candidiasis is a marker of progressive immune deficiency. Because of the frequently marked and prompt immune reconstitution induced by HAART, there is no recommendation for primary antifungal prophylaxis of mucosal candidiasis in the HIV setting in Europe, although it has been evidenced as effective in the pre-HAART era. Fluconazole remains the first line of therapy for both oropharyngeal candidiasis and oesophageal candidiasis and should be preferred to itraconazole oral solution (or capsules when not available) due to fewer side effects. For patients who still present with fluconazole-refractory mucosal candidiasis, oral treatment with any other azole should be preferred based on precise Candida species identification and susceptibility testing results in addition to the optimization of HAART when feasible. For vaginal candidiasis, topical therapy is preferred.

Abstract
Fungal diseases still play a major role in morbidity and mortality in patients with haematological malignancies, including those undergoing haematopoietic stem cell transplantation. Although Aspergillus and other filamentous fungal diseases remain a major concern, Candida infections are still a major cause of mortality. This part of the ESCMID guidelines focuses on this patient population and reviews pertaining to prophylaxis, empirical/pre-emptive and targeted therapy of Candida diseases. Anti-Candida prophylaxis is only recommended for patients receiving allogeneic stem cell transplantation. The authors recognize that the recommendations would have most likely been different if the purpose would have been prevention of all fungal infections (e.g. aspergillosis). In targeted treatment of candidaemia, recommendations for treatment are available for all echinocandins, that is anidulafungin (AI), caspofungin (AI) and micafungin (AI), although a warning for resistance is expressed. Liposomal amphotericin B received a BI recommendation due to higher number of reported adverse events in the trials. Amphotericin B deoxycholate should not be used (DII); and fluconazole was rated CI because of a change in epidemiology in some areas in Europe. Removal of central venous catheters is recommended during candidaemia but if catheter retention is a clinical necessity, treatment with an echinocandin is an option (CII(t) ). In chronic disseminated candidiasis therapy, recommendations are liposomal amphotericin B for 8 weeks (AIII), fluconazole for >3 months or other azoles (BIII). Granulocyte transfusions are only an option in desperate cases of patients with Candida disease and neutropenia (CIII).

Abstract
Invasive Candida infections are important causes of morbidity and mortality in immunocompromised and hospitalised patients. This article provides the joint recommendations of the German-speaking Mycological Society (Deutschsprachige Mykologische Gesellschaft, DMyKG) and the Paul-Ehrlich-Society for Chemotherapy (PEG) for diagnosis and treatment of invasive and superficial Candida infections. The recommendations are based on published results of clinical trials, case-series and expert opinion using the evidence criteria set forth by the Infectious Diseases Society of America (IDSA). Key recommendations are summarised here: The cornerstone of diagnosis remains the detection of the organism by culture with identification of the isolate at the species level; in vitro susceptibility testing is mandatory for invasive isolates. Options for initial therapy of candidaemia and other invasive Candida infections in non-granulocytopenic patients include fluconazole or one of the three approved echinocandin compounds; liposomal amphotericin B and voriconazole are secondary alternatives because of their less favourable pharmacological properties. In granulocytopenic patients, an echinocandin or liposomal amphotericin B is recommended as initial therapy based on the fungicidal mode of action. Indwelling central venous catheters serve as a main source of infection independent of the pathogenesis of candidaemia in the individual patients and should be removed whenever feasible. Pre-existing immunosuppressive treatment, particularly by glucocorticosteroids, ought to be discontinued, if feasible, or reduced. The duration of treatment for uncomplicated candidaemia is 14 days following the first negative blood culture and resolution of all associated symptoms and findings. Ophthalmoscopy is recommended prior to the discontinuation of antifungal chemotherapy to rule out endophthalmitis or chorioretinitis. Beyond these key recommendations, this article provides detailed recommendations for specific disease entities, for antifungal treatment in paediatric patients as well as a comprehensive discussion of epidemiology, clinical presentation and emerging diagnostic options of invasive and superficial Candida infections.

Abstract
The widespread use of antiretroviral therapy (ART) has entirely changed the management of human immunodeficiency virus (HIV) infection and dramatically reduced the rates of opportunistic infections (OI). However, OI continue to cause significant morbidity and mortality in both developed countries, where presentation with advanced HIV infection is common, and also in developing countries where ART is less widely available. Evidence to direct OI guidelines is partly limited by the fact that many large-scale studies date from the pre-ART era and more recent studies are sometimes poorly powered due to the falling rates of OI. Treatment of OI is now known to be as much about antimicrobials as about immune reconstitution with ART, and recent studies help guide the timing of initiation of ART in different infections. OI have also become complicated by the immune reconstitution inflammatory syndrome phenomenon which may occur once successful immune recovery begins. Trimethoprim-sulfamethoxazole has long been one of the most important antibiotics in the treatment and prevention of OI and remains paramount. It has a broad spectrum of activity against Pneumocystis jiroveci, toxoplasmosis, and bacterial infections and has an important role to play in preventing life-threatening OI. New advances in treating OI are coming from a variety of quarters: in cytomegalovirus eye disease, the use of oral rather than intravenous drugs is changing the face of therapy; in cryptococcal meningitis, improved drug formulations and combination therapy is improving clearance rates and reducing drug toxicities; and in gut disease, the possibility of rapid immune restitution with ART is replacing the need for antimicrobials against cryptosporidia and microsporidia.

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
Mucocutaneous candidiasis is frequently one of the first signs of HIV infection. Over 90% of patients with AIDS will develop oropharyngeal candidiasis at some time during their illness. Although numerous antifungal agents have been developed, azoles, both topical (clotrimazole) and systemic (fluconazole, itraconazole, voriconazole and posaconazole), have replaced older topical antifungals (gentian violet and nystatin) in the management of oropharyngeal candidiasis in these patients. The systemic azoles are generally safe and effective agents in HIV-infected patients with oropharyngeal candidiasis. A constant concern in these patients are relapses, which depend on the degree of immunosuppression and are commonly encountered after topical therapy rather than with systemic azole therapy. In patients with fluconazole-refractory mucosal candidiasis, treatment options now include itraconazole solution, voriconazole, posaconazole and the newer echinocandins (caspofungin, micafungin and anidulafungin). The objective of this article is to review the epidemiology, diagnosis and newer management modalities of oropharyngeal and esophageal candidiasis in HIV-infected individuals.

The systemic azoles, are generally safe and effective agents in HIV-infected patients with oropharyngeal candidiasis. A constant concern in these patients is relapse, which is dependent on the degree of immunosuppression commonly seen after topical therapy, rather than with systemic azole therapy. Candida esophagitis (CE) is also an important concern since it occurs in more than 10% of patients with AIDS and can lead to a decrease in oral intake and associated weight loss. Fluconazole has become the most widely used antifungal in the management of mucosal candidiasis. However, itraconazole and posaconazole have similar clinical response rates as fluconazole and are also effective alternative agents. In patients with fluconazole-refractory mucosal candidiasis, treatment options now include itraconazole solution, voriconazole, posaconazole, and the newer echinocandins (caspofungin, micafungin, and anidulafungin).

Abstract
Guidelines for the management of patients with invasive candidiasis and mucosal candidiasis were prepared by an Expert Panel of the Infectious Diseases Society of America. These updated guidelines replace the previous guidelines published in the 15 January 2004 issue of Clinical Infectious Diseases and are intended for use by health care providers who care for patients who either have or are at risk of these infections. Since 2004, several new antifungal agents have become available, and several new studies have been published relating to the treatment of candidemia, other forms of invasive candidiasis, and mucosal disease, including oropharyngeal and esophageal candidiasis. There are also recent prospective data on the prevention of invasive candidiasis in high-risk neonates and adults and on the empiric treatment of suspected invasive candidiasis in adults. This new information is incorporated into this revised document.

Abstract
This article reviews risk factors, prevention and management of oesophageal candidiasis (OC) in the elderly. Putative risk factors for OC in the elderly include old age itself, malignant disease, antibacterial and corticosteroid use, chronic obstructive pulmonary disease, acid suppression treatment, oesophageal dysmotility and other local factors, diabetes mellitus and HIV/AIDS. We have found evidence for a risk association between OC in the elderly and malignant disease (both haematological and non-haematological), antibacterial therapy and corticosteroid (including inhaled corticosteroids) use. We also found evidence of an association between OC in the elderly and oesophageal dysmotility or HIV/AIDS, but little direct evidence of an association between diabetes or old age per se. The literature on OC in the elderly is not large. The published series evaluating OC in this age group are small in size, often do not contain controls and mostly contain only limited information about the age of the patients. Prevention of OC is mainly the avoidance of exposure to the risk factors wherever possible. Specific measures such as highly active antiretroviral therapy in AIDS, prophylactic fluconazole when receiving chemotherapy for malignancy, using spacing devices, mouth rinsing soon after inhalation of corticosteroids and avoiding the use of cortiocosteroids just before bedtime are useful. OC is often responsive to a 2- to 3-week course of oral fluconazole, but resistance may be encountered in AIDS or in the presence of uncorrected anatomical factors in the oesophagus. Itraconazole solution, voriconazole or caspofungin may be used in refractory cases. Use of amphotericin B is restricted because of its narrow therapeutic index.

Abstract
BACKGROUND Until recently, available treatment for serious fungal infections comprised amphotericin B and azoles, which have limitations. Renal toxicity is a major concern with amphotericin B, while drug-drug interactions, hepatotoxicity, and skin rashes are the primary concerns with the azole medications. The development of the echinocandins, including caspofungin, has helped to fill the need for more efficacious antifungals that are useful across different patient populations and have a good safety profile. Anidulafungin is an echinocandin being developed to treat mucosal and invasive fungal infections. OBJECTIVE The aim of this report was to describe the pharmacodynamic and pharmacokinetic (PK) properties of anidulafungin. METHODS Data were identified using MEDLINE and National Library of Medicine Gateway searches for English-language literature (key words: anidulafungin, esophageal candidiasis, echinocandin, caspofungin, ravuconazole, voriconazole, posaconazole, micafungin, and fluconazole; years: 1996-2004), and from meeting abstracts of the American Society for Blood and Marrow Transplantation (Arlington Heights, Illinois), European Congress of Clinical Microbiology and Infectious Diseases (Basel, Switzerland), International Conference on Antimicrobial Agents and Chemotherapy (Washington, DC), and Infectious Diseases Society of America (Arlington, Virginia). RESULTS Anidulafungin has potent in vitro activity against Aspergillus and Candida spp, including those resistant to either fluconazole or amphotericin B. Results of several clinical trials imply that anidulafungin is effective in treating esophageal candidiasis (EC), candidemia, and invasive candidiasis (IC). In a Phase III, randomized, blinded clinical trial evaluating anidulafungin (50 mg/d) versus fluconazole (100 mg/d) for the treatment of EC, 97.2% and 98.9% of patients who received anidulafungin and fluconazole, respectively, showed evidence of cure or improvement (treatment difference, -1.6%; 95% CI, -4.1 to 0.8). In a Phase II study of candidasis and candidemia, anidulafungin showed success rates of 72%, 85%, and 83% in patients receiving the drug at dosages of 50, 75, or 100 mg/d, respectively. Studies evaluating the concomitant use of anidulafungin and either amphotericin, voriconazole, or cyclosporine did not show clinically significant drug-drug interactions or altered adverse-event (AE) profiles (P < 0.05). A population PK analysis showed no significant effect of age, race, concomitant medications, or renal or hepatic insufficiency on the PK properties of anidulafungin (P < 0.05). CONCLUSIONS Anidulafungin may offer a new option to treat serious fungal infections, such as EC, azole-refractory EC, candidemia, and IC. In addition, anidulafungin has been associated with no clinically significant drug-drug interactions and few treatment-related AEs. Anidulafungin may offer a new option in the management of serious and difficult-to-treat invasive fungal infections.

Abstract
We evaluated the safety and efficacy of primary systemic chemotherapy (PSC) with docetaxel (DOC), epirubicin (EPI) and capecitabine (Xeloda:XLD) in 10 patients with advanced breast cancer. Their mean age was 54.7 years,and preoperative stages were IIB, seven cases; IIIA, two; and IV, one,respectively. The regimen consisted of XLD (2,400 or 3,000 mg/day) orally for 14 consecutive days, and DOC (60 or 70 mg/m2) and EPI (50 or 60 mg/m2) intravenously on day 8. This was repeated 4 times every 3 weeks. One patient discontinued this regimen after one course at her own request. Although the results revealed leucopenia and neutropenia of more than grade 3 in 8 and 10 patients,they could be treated on an outpatient basis with the use of G-CSF to maintain this regimen. Alopecia of grade 2 was found in all patients,neutropenic fever of more than 38.5 degrees C in 5,and hand-foot syndrome in 3. Downstaging after PSC was demonstrated in 7 cases (Stage IIB to I, three cases; IIB to IIA, three; and III A to I, one), with a response rate of 77.8%. Breast conserving therapy was performed in 8/10 patients. Pathological findings on cytological degeneration showed grade 0, one; grade 1a,seven; grade 2, one; and grade 3, one, respectively. Axillary lymph node metastasis was revealed in 7 cases. This regimen would be an alternative to PSC on an outpatient basis while taking great care of myelosuppression and hand-foot syndrome.

Abstract
BACKGROUND Esophageal candidiasis (EC) remains one of the most common AIDS defining illnesses in patients with human immunodeficiency virus (HIV) in the era of highly active antiretroviral therapy (HAART), but little is known about factors associated with EC after starting HAART. OBJECTIVES To describe changes in the use of antimycotic medication, the incidence of EC and factors associated with EC before and after starting HAART. METHODS Patients from EuroSIDA, a pan-European longitudinal, prospective observational study. Generalized linear models and poisson regression models were used to investigate the relationships. RESULTS A total of 9,873 patients did not have EC at recruitment, subsequently 537 (15.8%) developed EC. The proportion of patients taking any antimycotic dropped from 18% at January 1995 to 2% at January 2004 (p < 0.0001); the duration of treatment declined from 10 to 3 months over the same period (p < 0.0001). There was a 32% annual decline in the incidence of EC (95% CI 30-35%, p < 0.0001). There was a significant annual decline in the incidence of EC pre-HAART in time-updated, adjusted models, (incidence rate ratio (IRR) 0.80, 95% CI 0.76-0.85, p < 0.0001) but not post-HAART (IRR 0.97; 95% CI 0.90-1.06, p= 0.54). Older patients and those with low CD4 counts had the greatest incidence of EC in the post-HAART era. CONCLUSIONS There has been a marked decline in the incidence of EC between 1994 and 2004. This was accompanied by a decline in markers associated with fungal disease, including use of antimycotics and a decline in duration of treatment.

Abstract
We determined the steady-state intrapulmonary pharmacokinetic and pharmacodynamic parameters of orally administered itraconazole (ITRA), 200 mg every 12 h (twice a day [b.i.d.]), on an empty stomach, for a total of 10 doses, in 26 healthy volunteers. Five subgroups each underwent standardized bronchoscopy and bronchoalveolar lavage (BAL) at 4, 8, 12, 16, and 24 h after administration of the last dose. ITRA and its main metabolite, 14-hydroxyitraconazole (OH-IT), were measured in plasma, BAL fluid, and alveolar cells (AC) using high-pressure liquid chromatography. Half-life and area under the concentration-time curves (AUC) in plasma, epithelial lining fluid (ELF), and AC were derived using noncompartmental analysis. ITRA and OH-IT maximum concentrations of drug (C(max)) (mean +/- standard deviation) in plasma, ELF, and AC were 2.1 +/- 0.8 and 3.3 +/- 1.0, 0.5 +/- 0.7 and 1.0 +/- 0.9, and 5.5 +/- 2.9 and 6.6 +/- 3.1 microg/ml, respectively. The ITRA and OH-IT AUC for plasma, ELF, and AC were 34.4 and 60.2, 7.4 and 18.9, and 101 and 134 microg. hr/ml. The ratio of the C(max) and the MIC at which 90% of the isolates were inhibited (MIC(90)), the AUC/MIC(90) ratio, and the percent dosing interval above MIC(90) for ITRA and OH-IT concentrations in AC were 1.1 and 3.2, 51 and 67, and 100 and 100%, respectively. Plasma, ELF, and AC concentrations of ITRA and OH-IT declined monoexponentially with half-lives of 23.1 and 37.2, 33.2 and 48.3, and 15.7 and 45.6 h, respectively. An oral dosing regimen of ITRA at 200 mg b.i.d. results in concentrations of ITRA and OH-ITRA in AC that are significantly greater than those in plasma or ELF and intrapulmonary pharmacodynamics that are favorable for the treatment of fungal respiratory infection.

Abstract
PLD-118, formerly BAY 10-8888, is a synthetic antifungal derivative of the naturally occurring beta-amino acid cispentacin. We studied the activity of PLD-118 in escalating dosages against experimental oropharyngeal and esophageal candidiasis (OPEC) caused by fluconazole (FLC)-resistant Candida albicans in immunocompromised rabbits. Infection was established by fluconazole-resistant (MIC > 64 microg/ml) clinical isolates from patients with refractory esophageal candidiasis. Antifungal therapy was administered for 7 days. Study groups consisted of untreated controls; animals receiving PLD-118 at 4, 10, 25, or 50 mg/kg of body weight/day via intravenous (i.v.) twice daily (BID) injections; animals receiving FLC at 2 mg/kg/day via i.v. BID injections; and animals receiving desoxycholate amphotericin B (DAMB) i.v. at 0.5 mg/kg/day. PLD-118- and DAMB-treated animals showed a significant dosage-dependent clearance of C. albicans from the tongue, oropharynx, and esophagus in comparison to untreated controls (P = 0.05, P = 0.01, P = 0.001, respectively), while FLC had no significant activity. PLD-118 demonstrated nonlinear plasma pharmacokinetics across the investigated dosage range, as was evident from a dose-dependent increase in plasma clearance and a dose-dependent decrease in the area under the plasma concentration-time curve. The biochemical safety profile was similar to that of FLC. In summary, PLD-118 demonstrated dosage-dependent antifungal activity and nonlinear plasma pharmacokinetics in treatment of experimental FLC-resistant oropharyngeal and esophageal candidiasis.

Abstract
Oropharyngeal candidiasis is a frequent infection in cancer patients who receive cytotoxic drugs. In this study, the efficacy, safety and tolerance of fluconazole and itraconazole were compared in non-neutropenic cancer patients with oropharyngeal candidiasis. Of 279 patients who were randomised between the two treatment groups, 252 patients were considered to be eligible (126 in each group). The clinical cure rate was 74% for fluconazole and 62% for itraconazole (P=0.04, 95% Confidence Interval (CI): 0.5-23.3%). The mycological cure rate was 80% for fluconazole and 68% for itraconazole (P=0.03, 95% CI: 1.2-22.6%). The safety and tolerance profile of both drugs were comparable. This study has shown that in patients with cancer and oropharyngeal candidiasis, fluconazole has a significantly better clinical and mycological cure rate compared with itraconazole.

Abstract
Invasive Candida and Aspergillus infections are among the most common serious complications occurring in chronically immunosuppressed patients, in particular those with hematological malignancies and transplant recipients. A rational, early systemic antifungal treatment can be based upon imaging diagnostic techniques as well as upon conventional mycological and non-culture-based procedures. The availability of well tolerable and highly efficacious systemic antifungals has improved the spectrum of therapeutic options and the success rates of antifungal treatment. However, with respect to high treatment costs associated with these new agents, it is mandatory to specify indications and limitations for the use of these substances. Voriconazole may well become the new standard primary treatment of invasive aspergillosis. The role of the new echinocandins such as caspofungin, which has recently been approved for salvage treatment of resistant and refractory Aspergillus infections, in primary or combination treatment of invasive aspergillosis must be further studied. Caspofungin is at least as effective as, yet significantly better tolerated than amphotericin B for primary treatment of invasive candidosis in non-neutropenic patients, and has been approved for this indication. The selection of systemic antifungals in patients with invasive Candida infection critically depends upon the identification of Candida species involved, because some non-albicans Candida spp. are resistant to azole antifungals.

Abstract
Esophageal disease is a common complication and cause of morbidity in patients with human immunodeficiency virus (HIV) infection. Opportunistic infections are the leading cause of esophageal complaints and may be a predictor of poor long-term prognosis, presumably as a reflection of severe underlying HIV immunodeficiency. The esophagus may be the site of the first acquired immunodeficiency syndrome (AIDS)-defining opportunistic illness in a large number of patients. Barium esophagography and upper gastrointestinal endoscopy are diagnostic modalities, commonly used to evaluate esophageal complaints in patients with AIDS. Treatment for most etiologies of esophagitis generally has a high degree of success, with a resultant improvement in quality of life. In addition to optimizing antiretroviral therapy, a thorough diagnostic assessment of every HIV-infected patient with esophageal complaints is warranted, followed by timely and appropriate treatment.

Abstract
In countries where highly active antiretroviral therapy (HAART) is widely available, a decrease in the incidence of fungal infections has been observed in the last 5 years compared with countries that cannot afford this treatment. Even refractory fungal infections may be controlled when HAART is given to patients, and end-stage AIDS infections, such as aspergillosis, are now only infrequently seen. In contrast, fungal infections in certain regions, such as penicilliosis in Southeast Asia or cryptococcosis in Sub-Saharan Africa, are a growing problem. Antifungal therapy for documented infections has not changed very much during recent years; however, new drugs such as caspofungin and voriconazole may be more effective in the treatment of opportunistic fungal infections, in particular, those involving resistant organisms. Secondary antifungal prophylaxis for many opportunistic pathogens can now be temporarily or even permanently discontinued in many HIV-positive patients who have a marked improvement in immune function parameters, such as CD4(+) cell counts, after initiation of HAART. The link between effective virustatic control of HIV infection and a decreasing incidence of fungal infections has been recognised; and so, despite the availability of very effective new antifungal drugs, the cornerstone of treatment and prevention of opportunistic fungal infections in patients with HIV infection is effective antiretroviral therapy including protease inhibitors.

Abstract
Oesophageal candidiasis is frequently one of the first signs of HIV infection, and a marker of HIV disease. Approximately 10% of patients with AIDS or other immunodeficiency, whether due to an underlying disease, chemotherapy or radiation therapy, will experience oesophageal candidiasis during their lifetime. In addition, unless the underlying immunodeficiency is corrected, approximately 60% of patients will experience a relapse within 6 months of the initial infection. The systemic azoles have gradually replaced the use of amphotericin B for oesophageal candidiasis, and are generally safely used and effective agents for this infection. A concern in some of these patients is the appearance of antifungal-refractory oesophageal candidiasis, which frequently leads to a vicious cycle of poor oral intake, weight loss, malnutrition and wasting syndrome, with occasional mortality due to malnutrition. Newer antifungals such as voriconazole and caspofungin, which are more potent in vitro and have a broader spectrum of activity, including activity against fluconazole-resistant Candida species are a welcome addition to the antifungal armamentarium that may be used in the management of refractory mucosal candidiasis.

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
V-echinocandin (VER-002; LY303366) is a semisynthetic derivative of echinocandin B and a potent inhibitor of fungal (1, 3)-beta-D-glucan synthase. We studied the antifungal efficacy, the concentrations in saliva and tissue, and the safety of VER-002 at escalating dosages against experimental oropharyngeal and esophageal candidiasis caused by fluconazole-resistant Candida albicans in immunocompromised rabbits. Study groups consisted of untreated controls, animals treated with VER-002 at 1, 2.5, and 5 mg/kg of body weight/day intravenously (i.v.), animals treated with fluconazole at 2 mg/kg/day i.v., or animals treated with amphotericin B at 0.3 mg/kg/day. VER-002-treated animals showed a significant dosage-dependent clearance of C. albicans from the tongue, oropharynx, esophagus, stomach, and duodenum in comparison to that for untreated controls. VER-002 also was superior to amphotericin B and fluconazole in clearing the organism from all sites studied. These in vivo findings are consistent with the results of in vitro time-kill assays, which demonstrated that VER-002 has concentration-dependent fungicidal activity. Esophageal tissue VER-002 concentrations were dosage proportional and exceeded the MIC at all dosages. Echinocandin concentrations in saliva were greater than or equal to the MICs at all dosages. There was no elevation of serum hepatic transaminase, alkaline phosphatase, bilirubin, potassium, or creatinine levels in VER-002-treated rabbits. In summary, the echinocandin VER-002 was well tolerated, penetrated the esophagus and salivary glands, and demonstrated dosage-dependent antifungal activity against fluconazole-resistant esophageal candidiasis in immunocompromised rabbits.

Abstract
Oropharyngeal candidiasis may be the first manifestation of human immunodeficiency viral (HIV) infection, and more than 90% of patients with the acquired immunodeficiency syndrome (AIDS) develop the disease. Although numerous antifungal agents are available, azoles, both topical (clotrimazole) and systemic (fluconazole, itraconazole), have largely replaced older topical antifungals (gentian violet, nystatin) in the management of the disease in these patients. A concern in these patients is clinical relapse, which appears to be dependent on degree of immunosuppression and is more common with clotrimazole and ketoconazole than with fluconazole or itraconazole. Candida esophagitis is also of concern, since it occurs in more than 10% of patients with AIDS. Fluconazole is an integral part of management. A cyclodextrin oral solution formulation of itraconazole has similar clinical response rates as fluconazole and is an effective alternative. In patients with fluconazole-resistant mucocutaneous candidiasis, treatment options include itraconazole and amphotericin B oral suspension and parenteral preparation.

Abstract
Mucocutaneous candidiasis, such as oropharyngeal candidiasis, esophageal candidiasis, and vulvovaginal candidiasis, are common problems in patients with HIV infection. These conditions adversely affect patient quality of life and morbidity status. New oral triazole agents provide improved treatment options for patients with these and other opportunistic fungal infections; however, the development of resistance in some Candida species poses new challenges. This article provides an overview of the diagnosis of mucocutaneous candidiasis, current treatment modalities, concomitant drug interactions, common adverse drug reactions, and the emergence of fungal resistance, and it suggests nursing interventions to maximize patient benefits from antifungal therapy.

Abstract
Although there have been dramatic strides in the therapy of human immunodeficiency virus infection over the last few years, the number of infected people world-wide is tremendous and, at least in developing countries, continues to expand. Complications which involve the gastrointestinal tract are common in these patients, because the gut is a major site for involvement by opportunistic infections and neoplasms in patients with the acquired immunodeficiency syndrome. It is important to recognize the clinical spectrum of gastrointestinal diseases, as well as the appropriate and most cost-effective diagnostic strategies, as therapies for a number of these disorders are both widely available and high effective. This review summarizes the major gastrointestinal infections which are seen in patients with the acquired immunodeficiency syndrome, and their treatment.
