Abstract
Background: Oropharyngeal/esophageal candidiasis are the most common opportunistic infections observed in patients with human immunodeficiency virus (HIV). While the commonly recommended treatment is fluconazole, relapse of oropharyngeal or esophageal candidiasis has been gradually increasing in recent decades.Methods: The current network meta-analysis (NMA) included randomized controlled trials (RCTs) investigating the efficacy and acceptability (i.e. drop-out rate) of different anti-fungal interventions against oropharyngeal or esophageal candidiasis in adults with HIV. All NMA procedures were conducted using the frequentist model.Results: Twenty-seven RCTs and 6277 participants were included. For oropharyngeal candidiasis, photosensitizer-based antimicrobial photodynamic therapy (aPDT) with laser irradiation plus methylene blue was associated with the highest cure rate and the lowest relapse rate among the investigated interventions [odds ratio (OR) = 6.82, 95% confidence intervals (95%CIs) = 0.19 to 244.42, p = 0.293, and OR = 0.03, 95%CIs = 0.00 to 0.77, p = 0.034, compared to fluconazole]. None of the investigated anti-fungal interventions were superior to fluconazole for esophageal candidiasis in respect of cure rates/relapse rates. All investigated anti-fungal interventions were well-accepted.Conclusions: aPDT could be the preferred strategy to manage oropharyngeal candidiasis; however the evidence for esophageal candidiasis still remained inconclusive.

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
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
BACKGROUND Oral candidiasis (OC) associated with human immunodeficiency virus (HIV) infection occurs commonly and recurs frequently, often presenting as an initial manifestation of the disease. Left untreated, these lesions contribute considerably to the morbidity associated with HIV infection. Interventions aimed at preventing and treating HIV-associated oral candidal lesions form an integral component of maintaining the quality of life for affected individuals. OBJECTIVES To determine the effects of any intervention in preventing or treating OC in children and adults with HIV infection. SEARCH STRATEGY The search strategy was based on that of the Cochrane HIV/AIDS Review Group. The following electronic databases were searched for randomised controlled trials for the years 1982 to 2005: Medline, AIDSearch, EMBASE and CINAHL. The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effectiveness, and the Cochrane Central Register of Controlled Trials (CENTRAL) were also searched through May 2005. The abstracts of relevant conferences, including the International Conferences on AIDS and the Conference on Retroviruses and Opportunistic Infections, as indexed by AIDSLINE, were also reviewed. The strategy was iterative, in that references of included studies were searched for additional references. All languages were included.The updated database search was done for the period 2005 up to 2009. The following databases were searched: Medline, EMBASE, the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effectiveness and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library. AIDSearch was not searched for the updated search as it ceased publication during 2008. SELECTION CRITERIA Randomised controlled trials (RCTs) of palliative, preventative or curative therapy were considered, irrespective of whether the control group received a placebo. Participants were HIV positive adults and children. DATA COLLECTION AND ANALYSIS Two authors independently assessed the methodological quality of the trials and extracted data. Study authors were contacted for additional data where necessary. MAIN RESULTS For the first publication of the review in 2006, forty studies were retrieved. Twenty eight trials (n=3225) met inclusion criteria. During the update search for the review a, further six studies were identified. Of these, five met the inclusion criteria and were included in the review. The review now includes 33 studies (n=3445): 22 assessing treatment and 11 assessing prevention of oropharyngeal candidiasis. Six studies were done in developing countries, 16 in the United States of America and the remainder in Europe.Treatment Treatment was assessed in the majority of trials looking at both clinical and mycological cures. In the majority of comparisons there was only one trial. Compared to nystatin, fluconazole favoured clinical cure in adults (1 RCT; n=167; RR 1.69; 95% CI 1.27 to 2.23). There was no difference with regard to clinical cure between fluconazole compared to ketoconazole (2 RCTs; n=83; RR 1.27; 95% CI 0.97 to 1.66), itraconazole (2 RCTs; n=434; RR 1.05; 95% CI 0.94 to 1.16), clotrimazole (2 RCTs; n=358; RR 1.14; 95% CI 0.92 to 1.42) or posaconazole (1 RCT; n=366; RR1.32; 95% CI 0.36 to 4.83). Two trials compared different dosages of fluconazole with no difference in clinical cure. When compared with clotrimazole, both fluconazole (2 RCTs; n=358; RR 1.47; 95% CI 1.16 to 1.87) and itraconazole (1 RCT; n=123; RR 2.20; 95% CI 1.43 to3.39) proved to be better for mycological cure. Both gentian violet (1 RCT; n=96; RR 5.28; 95% CI 1.23 to 22.55) and ketoconazole (1 RCT; n=92; RR 5.22; 95% CI 1.21 to 22.53) were superior to nystatin in bringing about clinical cure. A single trial compared gentian violet with lemon juice and lemon grass with no significant difference in clinical cure between the groups. Prevention Successful prevention was defined as the prevention of a relapse while receiving prophylaxis. Fluconazole was compared with placebo in five studies (5 RCTs; n=599; RR 0.61; 95% CI 0.5 to 0.74) and with no treatment in another (1 RCT; n=65; RR 0.16; 95% CI 0.08 to 0.34). In both instances the prevention of clinical episodes was favoured by fluconazole. Comparing continuous fluconazole treatment with intermittent treatment (2 RCTs; n=891; RR 0.65; 95% CI 0.23 to 1.83), there was no significant difference between the two treatment arms. Chlorhexidine was compared with normal saline in a single study with no significant difference between the treatment arms. AUTHORS' CONCLUSIONS Five new studies were added to the review, but their results do not alter the final conclusion of the review.Implications for practice Due to there being only one study in children, it is not possible to make recommendations for treatment or prevention of OC in children. Amongst adults, there were few studies per comparison. Due to insufficient evidence, no conclusion could be made about the effectiveness of clotrimazole, nystatin, amphotericin B, itraconazole or ketoconazole with regard to OC prophylaxis. In comparison to placebo, fluconazole is an effective preventative intervention. However, the potential for resistant Candida organisms to develop, as well as the cost of prophylaxis, might impact the feasibility of implementation. No studies were found comparing fluconazole with other interventions. The direction of findings suggests that ketoconazole, fluconazole, itraconazole and clotrimazole improved the treatment outcomes.Implications for research It is encouraging that low-cost alternatives are being tested, but more research needs to be on in this area and on interventions like gentian violet and other less expensive anti-fungal drugs to treat OC. More well-designed treatment trials with larger samples are needed to allow for sufficient power to detect differences in not only clinical, but also mycological, response and relapse rates. There is also a strong need for more research to be done on the treatment and prevention of OC in children as it is reported that OC is the most frequent fungal infection in children and adolescents who are HIV positive. More research on the effectiveness of less expensive interventions also needs to be done in resource-poor settings. Currently few trials report outcomes related to quality of life, nutrition, or survival. Future researchers should consider measuring these when planning trials. Development of resistance remains under-studied and more work must be done in this area. It is recommended that trials be more standardised and conform more closely to CONSORT.

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.

Abstract
Mucocutaneous candidiasis is frequently one of the first signs of human immunodeficiency virus (HIV) infection. Over 90% of patients with AIDS will develop oropharyngeal candidiasis (OPC) at some time during their illness. Although numerous antifungal agents are available, azoles, both topical (clotrimazole) and systemic (fluconazole, itraconazole, voriconazole, 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 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
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
Anidulafungin is a novel antifungal agent of the echinocandin class. This randomized, double-blind, double-dummy study compared the efficacy and safety of intravenous anidulafungin to that of oral fluconazole in 601 patients with endoscopically and microbiologically documented esophageal candidiasis. Patients received intravenous anidulafungin (100 mg on day 1, followed by 50 mg per day) or oral fluconazole (200 mg on day 1, followed by 100 mg per day) for 7 days beyond resolution of symptoms (range, 14-21 days). At the end of therapy, the rate of endoscopic success for anidulafungin (242 [97.2%] of 249 treated patients) was found to be statistically noninferior to that for fluconazole (252 [98.8%] of 255 treated patients; treatment difference, -1.6%; 95% confidence interval, -4.1 to 0.8). The safety profile of anidulafungin was similar to that of fluconazole; treatment-related adverse events occurred in 9.3% and 12.0% of patients, respectively. Laboratory parameters were similar between treatment arms. Anidulafungin is as safe and effective as oral fluconazole for the treatment of esophageal candidiasis, when assessed at the completion of therapy.

Abstract
BACKGROUND Severely immunocompromised individuals are highly susceptible to Candida infection of the esophagus. This randomized, double-blind study assessed the dose-response relationship of the new echinocandin antifungal, micafungin, compared with that of standard fluconazole treatment. METHODS A total of 245 patients (age, > or =18 years) with a prior diagnosis of acquired immunodeficiency syndrome/human immunodeficiency virus (HIV) infection and esophageal candidiasis, confirmed by endoscopy and culture, were randomized to receive micafungin (50, 100, or 150 mg per day) or fluconazole (200 mg per day). Both agents were administered once per day by a 1-h intravenous infusion for 14-21 days. The primary efficacy end point was endoscopic cure rate, defined as endoscopy grade of 0 at the end of therapy. RESULTS The endoscopic cure rate (grade 0) was dose-dependent with 50, 100, and 150 mg of micafungin per day at 68.8%, 77.4%, and 89.8%, respectively. Symptoms improved or resolved rapidly (3-7 days of treatment in the majority of patients). The endoscopic cure rate for 100 and 150 mg of micafungin per day (83.5%) was comparable to that for 200 mg of fluconazole per day (86.7%; 95% confidence interval for the difference in endoscopic cure rate, -14.0% to 7.7%). The overall safety and tolerability was acceptable, with no important differences between micafungin (all doses) and fluconazole. CONCLUSIONS The dose-response findings demonstrate a greater efficacy with micafungin at 100 and 150 mg per day than at 50 mg per day. This study also indicates that the efficacy of micafungin (at dosages of 100 and 150 mg per day) was comparable to that of fluconazole, suggesting that micafungin represents a valuable new treatment option for esophageal candidiasis in HIV-positive patients.

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
Mucosal adherence and germ tube formation are considered to be important virulence factors of C. albicans. Adherence is a precondition for colonisation and invasion. We investigated 11 clinical isolates (among them 5 cases recovered from oesophageal thrush) for quantification of the two characteristics and correlated the results with clinical data. Adherence was measured on buccal epithelial cells and the continuous flow culture was used for quantification of germ tube formation. Adherence of strains recovered from clinically, culturally and serologically confirmed oesophageal thrush adhered stronger to buccal epithelial cells than isolates from patients with heavy colonisation without signs of candidosis. Strains with stronger adherence showed a significantly faster and an increased germ tube formation in the continuous flow culture. Strains from oesophageal thrush therefore show a more marked expression of the investigated virulence factors. Therefore a good adherence is a necessity for infection of the oesophagus by C. albicans. The preferential isolation of C. albicans from oesophageal thrush (> 90%) supports this assumption.

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
Traditionally, amphotericin B has been the cornerstone of antifungal treatment. Toxicity, however, is a major dose-limiting factor of amphotericin B deoxycholate. Nevertheless, it continues to have a major role in the treatment of deep-seated mycotic infections. Recently, less nephrotic lipid formulations, including amphotericin B lipid complex, amphotericin B cholesteryl sulfate, and liposomal amphotericin B, have been introduced. The pharmacologic properties, main indications, recommended dosages, related costs, and adverse effects of these various preparations are summarized in this review. Orally administered flucytosine is useful in certain infections, particularly cryptococcal meningitis, but it should be used with caution in patients with renal insufficiency.

Abstract
Mucosal adherence and germ tube formation have been considered as important virulence factors of Candida albicans. We investigated 11 clinical isolates (among them six isolates from oesophageal thrush) for quantification of adherence to buccal epithelial cells and germ tube formation in the continuous flow culture in vitro, and correlated the results with the clinical data of the patients. Adherence varied considerably between the different C. albicans strains. Strains recovered from clinically, culturally and serologically confirmed oesophageal thrush adhered stronger to buccal epithelial cells. Isolates from cases with heavy colonisation but clinically without candidosis were less adherent. Only after 30 min germ tube formation was observed in the continuous flow culture. Strains with stronger adherence also showed significantly faster and increased germ tube formation. The patients with oesophageal thrush did not suffer any particular immunosuppression such as HIV infection, although in most cases chronic alcoholism was apparent. We conclude, that in cases with minor immunosuppression the expression of the virulence factors adherence and germ tube formation plays an important role in the pathogenesis of candidosis, whereas it may be of less importance in cases with severe immunosuppression. In the latter they may, however, influence outcome.

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.

Abstract
STUDY OBJECTIVE To assess the role and the therapeutic efficacy of fluconazole and itraconazole-flucytosine association compared with placebo, in the treatment of endoscopically diagnosed esophageal candidiasis in a selected population of AIDS patients. DESIGN Double-blind, placebo-controlled study. SETTING University Hospitals and AIDS Centers. PATIENTS Eighty-five HIV-positive patients (53 men and 32 women; mean age, 28 years) at first episode of esophageal candidiasis diagnosed by endoscopy (grades I to II of Kodsi's endoscopic classification and grades I to IIa of Barbaro's clinical classification). All the patients selected for the study provided informed consent. INTERVENTIONS The patients have been double blindly randomized in 3 groups of patients in relation to pharmacologic therapy: (1) the patients of the first group (n = 30) received fluconazole (3 mg/kg daily orally) and placebo (100 mg/kg/daily orally); (2) the patients of the second group (n = 30) received itraconazole (3 mg/kg daily orally) and flucytosine (100 mg/kg daily orally); and (3) the patients of the third group (n = 25) received placebo (3 mg/kg daily orally) and placebo (100 mg/kg daily orally). After 2 weeks of treatment, the patients previously randomized to receive placebo only were double blindly randomized to receive fluconazole+placebo or itraconazole+flucytosine. To evaluate the efficacy of pharmacologic therapy, clinical and endoscopic examinations were performed at weeks 2 and 4 and at the end of follow-up (3 months). RESULTS At week 2, endoscopic cure (grade 0) was observed in 68.9% of the fluconazole+placebo group and in 72.4% of the itraconazole+flucytosine group (relative risk, 0.95; 95% confidence interval [CI], 0.68 to 1.33; p = 0.772); partial endoscopic response (grade I) was observed in 22.7% of the placebo group. Clinical cure (grade 0) was observed in 75.8% of fluconazole+placebo group and in 72.4% of itraconazole+flucytosine group (relative risk, 1.05; 95% CI, 0.77 to 1.42; p = 0.764), with a difference statistically significant for both treatments in comparison to placebo group (p < 0.001). Partial clinical response (grade I) was observed in 27.3% of the placebo group. At the end of follow-up, endoscopic cure was observed in 89.8% of the fluconazole+placebo group and in 94.8% of the itraconazole+flucytosine group (relative risk, 0.97; 95% CI, 0.83 to 1.08; p = 0.695). Clinical cure was observed in 94.8% of the fluconazole+placebo group and in 97.3% of the itraconazole+flucytosine group (relative risk, 0.97; 95% CI, 0.89 to 1.07; p = 0.981). CONCLUSIONS The results of this study have demonstrated that both fluconazole and itraconazole+flucytosine association are efficacious in short-term treatment of esophageal candidiasis in AIDS patients with a statistically significant difference in comparison to placebo. Both therapeutic regimens demonstrated a good therapeutic efficacy, without statistically significant difference, between them, in the rate of endoscopic and clinical cure. Itraconazole+flucytosine association may represent an alternative therapeutic regimen for patients with fluconazole-resistant Candida esophagitis.
