Oropharyngeal candidiasis and radiotherapy  

International Nuclear Information System (INIS)

The oropharyngeal candidiasis is a common condition in cancer patients treated by irradiation, during and after their treatment. For example, almost 70% of patients treated with chemo-radiation for head and neck cancer are colonized, and 40% of symptomatic patients have an oropharyngeal candidiasis. Furthermore, we noticed an increase in non-albicans Candida strains, which are present in almost 50% of samples. Cancer treatments, especially radiation therapy, and co-morbidities are risk factors of oropharyngeal candidiasis. Oropharyngeal candidiasis has substantial effects on quality of life, and may limit treatment. Epidemiologic data, physiopathology, clinical diagnosis criteria, consequences and treatment of oropharyngeal candidiasis will be discussed in this article. (authors)

Candidemia and systemic candidiasis.  

Science.gov (United States)

The growing problem of candidemia and systemic candidiasis reflects the enormous increase in the pool of patients at risk as well as the increased opportunity that exists for Candida sp to invade tissues normally resistant to invasion. Candida sp, as truly opportunistic pathogens, exploit recent technological advances to gain access to the circulation and deep tissues. The increased prevalence of local and systemic disease caused by Candida organisms has resulted in new clinical syndromes, the expression of which depends upon the immune status of the host. These new syndromes include the focal hepatosplenic candidiasis, Candida peritonitis and systemic candidiasis. Management of serious and life-threatening invasive candidiasis remains severely hampered by the lack of reliable diagnostic methods that would allow early detection of both fungemia and tissue invasion by Candida organisms. Amphotericin B remains the cornerstone of effective antifungal therapy in systemic candidiasis. Over the last decade, new principles have emerged, including shorter and lower dosage regimens for catheter-related candidemia. The newer oral azoles may play a useful role in the management of invasive candidiasis. PMID:2247707

Invasive candidiasis during granulocytopenia.  

Science.gov (United States)

Candidiasis remains the most frequently encountered fungal infection in patients with profound granulocytopenia and appears to be increasing in frequency. In addition, Candida infections are occurring earlier during remission induction chemotherapy and can be caused by a variety of species such as C. albicans, C. tropicalis, and C. krusei. The most frequent source of disseminated infection is the gastrointestinal tract, as the integrity of the epithelium is disrupted by chemotherapeutic agents. The spectrum of disseminated candidiasis comprises both an acute and a chronic presentation (also known in the literature as hepatosplenic candidiasis). The management of disseminated infection consists of early empiric antifungal therapy with a standard agent, amphotericin B. Unfortunately, responses in the setting of profound granulocytopenia appear to be poor. Other agents that appear to be useful in the management of disseminated candidiasis include 5-flucytosine and fluconazole. Based on animal experimentation, it appears that the combination of these three classes of agents might produce superior results compared with amphotericin B alone. Removal of the central venous catheter does not appear warranted in the setting of profound granulocytopenia, and the role of colony stimulating factors needs to be defined. Given the severity and high mortality associated with disseminated candidiasis in patients with hematologic malignancies, antifungal prophylaxis appears warranted. PMID:8265854

Mouse Model of Oropharyngeal Candidiasis  

Science.gov (United States)

Oropharyngeal candidiasis is a frequent cause of morbidity in patients with defects in cell-mediated immunity or saliva production. Animal models of this infection are important for studying disease pathogenesis and evaluating vaccines and antifungal therapies. Here we describe a simple murine model of oropharyngeal candidiasis. Mice are rendered susceptible to oral infection by injection with cortisone acetate and then inoculated by placing a swab saturated with Candida albicans sublingually. This process results in a reproducible level of infection, the histopathology of which mimics that of pseudomembranous oropharyngeal candidiasis in patients. Using this model, data are obtained after 5–9 days of work.

Hepatosplenic candidiasis: wheels within wheels.  

Science.gov (United States)

Eight immunocompromised cancer patients with tissue-proved candidiasis underwent serial abdominal ultrasound (US) and computed tomography (CT). At US, four patterns of hepatic and splenic candidiasis were recognized, one of which the authors call a "wheels-within-wheels" pattern. In addition, periportal linear areas of increased attenuation, possibly calcified, were identified at follow-up, nonenhanced CT. Some abscesses were better seen on nonenhanced CT scans, while others became visible only with enhancement. Although lesions not seen at US were often seen at CT, the opposite was also true. In two cases, pathologic proof of candidiasis was established even when all imaging studies were normal. For maximum imaging sensitivity, patients should be studied with US and nonenhanced and enhanced CT. Even when both US and CT scans are negative, if there is a strong clinical suggestion of candidiasis, open biopsy is recommended. PMID:3275982

Oral Candidiasis and Oral Hyperplastic Candidiasis: Clinical Presentation  

Directory of Open Access Journals (Sweden)

Full Text Available Oral candidiasis is an opportunistic infection of the oral cavity. It is common and underdiagnosed among the elderly, particularly in those who wear dentures and in many cases is avoidable with a good mouth care regimen. It can also be a mark of systemic disease, such as diabetes mellitus and is a common problem among the immunocompromised. Oral candidiasis is caused by an overgrowth or infection of the oral cavity by a yeast-like fungus, candida.The important ones are C albicans, C tropicalis, C glabrata , C pseudotropicalis, C guillierimondii, C krusei, C lusitaniae, C parapsilosis and C stellatoidea. C albicans, C glabrata and C tropicalis represent more than 80% of isolates from clinical infection. Oral candidiasis is the most common human fungal infection especially in early and later life. The incidence varies depending on age and certain predisposing factors. There are three broad groupings consisting of acute candidiasis, chronic candidiasis and angular cheilitis. Chronic hyperplastic candidosis/candidiasis (CHC; syn. candidal leukoplakia is a variant of oral candidosis that typically presents as a white patch on the commissures of the oral mucosa. Risk factors include impaired salivary gland function, drugs, dentures, high carbohydrate diet, smoking, diabetes mellitus, Cushing`s syndrome, malignancies and immunosuppressive conditions. The aim of the research is to describe the clinical manifestations of the disease.

Hepatosplenic candidiasis, a fatal disease?  

Science.gov (United States)

We report on two patients with acute leukemia and prolonged granulocytopenia after cytotoxic therapy in whom the diagnosis hepatosplenic candidiasis was made. Both patients developed upper abdominal discomfort with elevated alkaline phosphatase after resolution of granulocytopenia. The diagnosis was established by demonstration of multiple abscesses in liver and spleen on ultrasound and computed tomography. Both patients were initially treated with amphotericin B i.v., one of them received liposomal amphotericin B (cumulative dose of 2,530 mg and 570 mg, respectively). Thereafter, therapy was continued for months with oral fluconazole. The treatment of hepatosplenic candidiasis was successful, however, the patients died from relapse and progression of leukemia.

Hepatosplenic candidiasis. A manifestation of chronic disseminated candidiasis.  

Science.gov (United States)

Much progress has been made over the last decade in diagnosing and treating CDC, a chronic and debilitating infection that interferes with the delivery of intensive cytotoxic chemotherapy in patients with leukemia. The use of fluconazole prophylaxis in these patients has decreased the incidence of CDC dramatically. The greatest future challenges are gaining a better understanding of its pathophysiology, and the continued development of effective diagnostic and therapeutic strategies to treat this unusual manifestation of systemic candidiasis.

[Systemic candidiasis in children with cancer].  

Science.gov (United States)

Systemic fungal infections have long been recognized in terminally ill patients with cancer. Systemic candidiasis is the most common, the incidence having increased in the last few years. Eight children diagnosed as having systemic candidiasis during a two-year period (1987-1988) are presented. Three had an isolated fungal pneumonitis, two an hepatosplenic candidiasis, one a multisystemic involvement (hepatosplenic, pulmonary and nodular skin lesions) and the remaining two patients had a Candida sepsis with no visceral lesions having been documented. All patients had neutropenia and prolonged fever no responsive to broad spectrum antibiotics. We would like to underline the importance of an early and prolonged antifungal therapy, especially in hepatosplenic candidiasis, in order to obtain the cure. PMID:2619132

Rethinking T cell immunity in oropharyngeal candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The disproportionate increase in oropharyngeal candidiasis (OPC) compared with systemic and vaginal candidiasis in female patients with AIDS has been a paradox for almost three decades. New data now show that severe OPC develops in Th17-deficient mice, but not Th1-deficient mice, implicating Th17-induced effector molecules in resistance to oral disease. These findings clarify and extend our current thinking about how CD4 T cell deficiency influences susceptibility to OPC.

Profile of Candidiasis in HIV Infected Patients  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objective: Candidiasis is a common opportunistic infection in HIV-infected patients. The spectrum of Candida infection is diverse, starting from asymptomatic colonization to pathogenicforms. The low absolute CD4+ T-lymphocyte count has traditionally been cited as the greatest risk factor for the development of Oropharyngeal Candidiasis and current guidelines suggest increased risk once CD4+ T lymphocyte counts fall below 200 cells/?L. Gradual emergence of non-albicans Candida species as a cause of refractory mucosal and invasive Candidiasis, particularly in patients with advanced immunosuppression and problem of resistance to azoles and other antifungal agents in the Candida species is a point of concern.Materials and Methods: A prospective study was carried out over a period of 2 years (2010-2011 on patients suffering from AIDS for the presence of Candida infection. After thorough clinical examination relevant specimens were collected and processed specifically to ascertain Candida infection. Speciation of Candida isolates and antifungal sensitivity testing was also done. The CD4 cell counts of all the patients were estimated and correlated with the presence (or absence of candidiasis.Results: Out of a total of 165 HIV positive patients, a definitive diagnosis of candidiasis was made in 80 patients. Candida albicans was the most common yeast isolated. Patients with candidiasis had CD4 counts less than 200 cells/mm3. Maximum resistance was seen with fluconazole while no resistance was seen with voriconazole.Conclusion: The most common opportunistic fungal infection in HIV positive patients is candidiasis, affecting the mucocutaneous system mainly but the invasive form is also common. Resistance to azoles and other antifungal agents in the Candida species is a point of concern.

Risk factors for recurrent vulvovaginal candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Background/Aim. Recurrent vulvovaginal candidiasis is relatively frequent condition, and may have serious health consequences, like chronic vulvovaginal pain syndrome. The aim of our study was to determine possible risk factors for recurrent vulvovaginal candidiasis in non-pregnant females within the reproductive age. Methods. The design of our study was of a case-control type. Case and control patients were selected from the gynecological patients at six primary care facilities in Serbia and in Montenegro. The data on the patients' health condition, concomitant therapy and diseases were taken from their records, and the data on habits were obtained by unstructured interview. For potential risk factors crude odds ratios were calculated, and then adjusted by logistic regression. Results. A total of fifty-one patients had four or more episodes of vulvovaginal candidiasis during the last year (cases, and 132 patients with one to three episodes of vulvovaginal candidiasis were sampled as controls, matched by age. The only two significant associations were found between recurrent vulvovaginal candidiasis and continual wearing of panty liners during the last year (Odds ratio - ORadjusted: 3.97; confidence interval - CI: 1.57-10.02; p = 0.004, and between recurrent vulvovaginal candidiasis and predominant use of vaginal tampons during menstruation in the last year (ORadjusted: 4.25; CI: 1.11-16.27; p = 0.035. The synergistic effect was observed for the concurrent continual wearing of panty liners during the last year and selfmedication with antimycotics. Conclusions. Local factors, like wearing of panty liners or use of tampons during menstruation, may promote recurrence of vulvovaginal candidiasis, especially in patients who practice selfmedication with antimycotics.

Cutaneous candidiasis is a disease that affects children as well as adults. The presentation may be localized or systemic, and with multiple etiological agents. The most prevalent infecting species in children differs from that of the adult. Objective. A case is presented where a conge [...] nital cutaneous candidiasis was transmitted to the child during birth. Materials and methods. A full term newborn was exposed to a subclinical vaginal candidiasis infection, and 24 hr after birth, developed congenital cutaneous candidiasis. The etiological agent was Candida albicans, and was associated with sepsis and respiratory distress. Blood cultures, cutaneous biopsy of vesicular lesions, blood tests and lumbar puncture were performed. Results. Biochemistry and blood count showed a CRP of 5.7 mg/dl, leukocytosis with left shift and mild anemia. After 24 hr, the blood analyses showed an increase in a CRP (7.8 mg/dl) and increased progressively for three days; consequently, a lumbar puncture was performed. Blood culture was positive for Staphylococcus aureus. Cutaneous biopsy confirmed the cutaneous candidiasis. Conclusions. The early diagnosis is essential to prevent complications derived by the Candida albicans in newborns.

Fluconazole in the treatment of hepatosplenic candidiasis.  

Science.gov (United States)

Hepatosplenic candidiasis has increased in frequency among immunocompromised hosts. Risk factors include hematologic malignancy, intensive chemotherapy, prolonged neutropenia, and treatment with broad-spectrum antibiotics. Patients most commonly present with abdominal pain, persistent fevers despite antibiotic therapy, and an elevated alkaline phosphatase level that is out of proportion to other hepatic enzyme levels. Gastrointestinal mucosal damage secondary to intensive chemotherapy may allow colonization with Candida species and subsequent seeding of the portal vein. Treatment has consisted of prolonged courses of amphotericin B, with mortality rates approaching 50%. We report a case of hepatosplenic candidiasis in a patient with acute myelogenous leukemia who had clinical and radiographic improvement during fluconazole therapy. Fluconazole may be an efficacious and less toxic alternative to amphotericin B. PMID:1739374

The diagnosis was based on prolonged fever, elevated serum bilirubin and alkaline phosphatase, as well as characteristic lesions on computed tomography, nuclear magnetic resonance and ultrasonographic findings and positive blood culture in one patient. The antifungal treatment was successful in one patient only. Two patients died due to progression of leukemia. CONCLUSION If leukemia patient in remission after chemotherapy develops a prolonged fever of unknown origin, hepatosplenic candidiasis has to be considered and all efforts should be done to diagnose it. The diagnosis is based on clinical presentation and imaging techniques. The positive cultures of fungi are not usually possible and are not mandatory. The antifungal treatment may be prolonged, sometimes 2 to 3 months or even more.

Se presenta el caso clínico de un varón de 31 años, con leucemia mieloide aguda (LMA) M2, internado en el [...] Servicio de Clínica Médica del hospital, que luego del tratamiento quimioterápico de inducción y consolidación presentó neutropenia febril leve. La candidiasis hepatoesplénica fue diagnosticada por tomografía axial computada (TAC) y biopsia hepática. El enfermo fue tratado con anfotericina B, seguida de la forma liposomal hasta completar los 4 g. Se le dió el alta en espera de transplante de médula ósea. En este paciente se demostró que la sospecha temprana de candidiasis hepatoesplénica ayudó en la elección de un método de diagnóstico precoz y a su correcto tratamiento. Abstract in english Chronic diseminated candidiasis - mainly its hepatosplenic form- is one of the most characteristic invasive infection due to Candida in haematological patients. A case is presented of a 31 year old man admitted to the Clinical Department with acute mieloid leukosis M2, showing febrile neutropenia af [...] ter induction and consolidation chemotherapy. Hepatoesplenic candidiasis was diagnosed and confirmed by computered axial tomography (CAT) and hepatic biopsy; amphotericin B followed by liposome encapsuled amphotericin B up to complete a total dose of 4 g was used for treatment. The patient was discharged waiting for bone marrow transplantation. Early suspicion of hepatosplenic candidiasis helps to select a rapid diagnosis method and an effective treatment.

[Guidelines for diagnosis and treatment of mucocutaneous candidiasis].  

Science.gov (United States)

This document summarizes current knowledge about diagnosis and treatment of candidiasis affecting the skin and oral mucosa. Several clinical forms of mucocutaneous candidiasis are distinguished depending on a patient's age and infected site, e.g. Candida intertrigo, erythema mycoticum infantile, erosio interdigitalis blastomycetica, candidal paronychia and onychia, Candida onychomycosis, and oral candidiasis. The diagnosis of candidiasis is confirmed by observation of mycelial forms on microscopic examination. Since Candida yeasts (especially C. albicans) are normal inhabitants of the skin and oral mucosa, it must always be noted that positive culture does not always indicate the presence of candidal infection. The pathogenicity of Candida species is relatively low, and some special conditions are required for tissue invasion by the fungus. Predisposing factors, such as disturbances of the cutaneous and mucosal microenvironment and systemic or local immunosuppression, should be checked in patients with recurrent infection. Therapy for cutaneous candidiasis is dominated by topical antifungal agents. Azole antifungal cream (e.g., bifonazole, ketoconazole, neticonazole hydrochloride, lanoconazole and luliconazole) is most effective. Terbinafine hydrochloride and amorolfine hydrochloride are also useful. Cutaneous candidiasis usually requires a shorter duration of topical treatment (1-2 weeks) than superficial dermatophyte infections. For candidal paronychia and onychomycosis, oral therapy with itraconazole is recommended. The daily dose of itraconazole should be taken for several months, while its pulse therapy for candidiasis is not approved in Japan. Itraconazole oral solution is commonly used for oral candidiasis, and miconazole gel is also effective. PMID:19942790

CHRONIC MUCOCUTANEOUS CANDIDIASIS - A CASE REPORT  

Directory of Open Access Journals (Sweden)

Full Text Available Chronic mucocutaneous candidiasis(CMC is a rare group of overlapping syndromes that have in common a clinical pattern of persistent and diffuse cutaneous or mucosal candidal infections. It is usually associated with multiple endocrine dysfunctions and autoimmune disorders therefore patients needs a complete systemic evaluation. Patients of CMC are also susceptible to other fungal and viral infections due to impaired cell mediated immunity. We report a case of CMC wherein the cutaneous and mucosal lesions were not associated with any systemic disorder. The patient responded to topical clotrimazole.

We present the case of a preterm neonate who was born with respiratory distress and a papulovesicular rash that was diagnosed as congenital candidiasis (CC). The mother was asymptomatic. The cutaneous eruption and respiratory distress improved following treatment with systemic antifungals. Congenital candidiasis ranges in presentation from isolated cutaneous involvement to severe multisystem disease. Given its rarity among neonatal skin eruptions, heightened suspicion is required for prompt diagnosis and treatment. PMID:24897134

Local Production of Chemokines during Experimental Vaginal Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Recurrent vulvovaginal candidiasis, caused by Candida albicans, is a significant problem in women of childbearing age. Although cell-mediated immunity (CMI) due to T cells and cytokines is the predominant host defense mechanism against C. albicans at mucosal tissue sites, host defense mechanisms against C. albicans at the vaginal mucosa are poorly understood. Based on an estrogen-dependent murine model of vaginal candidiasis, our data suggest that systemic CMI is ineffective against C. albica...

Hepatosplenic candidiasis in children with acute leukemia.  

Science.gov (United States)

Three children with acute lymphoblastic leukemia developed disseminated fungal disease predominantly involving the liver and spleen. The three patients were undergoing induction chemotherapy and had neutropenia when they presented prolonged fever not responsive to antibiotics. Once neutropenia was recovered, hepatosplenomegaly leukocytosis, elevated serum alkaline phosphatase, and hypoechoic areas in the spleen and liver ultrasound were observed. All fungal blood cultures were negative, with the diagnosis being confirmed by histologic study. One of the patients died without achieving control of the candidiasis. The other two patients received prolonged antifungal treatment concurrently with chemotherapy and both are alive, one of them cured and in complete remission. The increasing frequency of this infection in recent years and the importance of a prompt and prolonged administration of antifungal therapy to obtain the cure are discussed. PMID:2297657

A clinico-pathological and cytological study of oral candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Candidiasis of the oral mucosa arises chiefly as a re- sult of infection with Candida albicans. Many clinico- pathological analyses of macroscopic findings have been described, although the clinical findings of oral candidiasis vary considerably and the conditions are complex. The present study analyzes the distribution, clinical, cytological and histological diagnoses of oral candidiasis, associated complex diseases and the di-agnostic value of cytology. The ratio of Candida in-fection was 28.9% among 1551 study participants. Females were infected significantly more often than men (p < 0.01 and the affected age range was 60 - 79 years (61.0%, p < 0.01. The predominantly affected areas were the tongue (48.3%, p < 0.01 and gingiva (20.0%, p < 0.01, and occurrence at multiple loci was seen in 43 (9.6% patients. The typical clinical find- ings of oral candidiasis were ulcerative/erythematous lesions (33.2%, p < 0.01 and pseudomembranous candidiasis (31.6%, p < 0.01. A histopathological dia- gnosis of candidiasis based on biopsy specimens from 26 lesions in patients with Candida infection indicated by cytology was confirmed from cultures. The break- down of a cytological to a definite diagnosis was 6 positive (SCC 4, verrucous carcinoma 1, moderate to severe dysplasia 1, 6 suspected positive (mild dyspla- sia, 2; moderate to severe dysplasia, 2; papilloma, 1 and SCC, 1 and 14 negative (epulis, 3; papilloma, 3; granulation tissue, 2; fibrosis, 2 and others, 4. Exfo-liative cytology can easily judge the presence of Can-dida species, although experience is necessary for the presumptive diagnosis of an oral mucosal disease. The application of exfoliative cytology using the Pe- riodic acid-Schiff reaction is helpful for the earlier detection of oral candidiasis with various macrosco- pic findings.

[Esophageal candidiasis as complication of inhaled steroid therapy].  

Science.gov (United States)

Gastrointestinal endoscopy was performed in two bronchial asthma patients using inhaled corticosteroid who complained of odynophagia. The endoscopic finding was high grade with white moss (Grade III) in both patients. Esophageal candidiasis is often recognized in bronchial asthmatic patients receiving long-term fluticasone propionate (FP) dry powder (Diskhaler) inhalation. We therefore examined the complicated context of esophageal candidiasis in patients with long-term FP inhalation. Out of 20 bronchial asthmatic patients who had been using FP inhalation long-term, seven showed signs of esophageal candidiasis. Three patients had mild grade (Grade I), one middle grade (Grade II) and three high grade (Grade III) candidiasis, with a frequency of 35%. This rate is higher than the usual spontaneous occurrence rate of esophageal candidiasis, and it is suggested that inhalation of corticosteroid medication can penetrate into the esophagus after deep inhalation. We tested this hypothesis in two studies. 1) To measure the esophageal concentration of FP, four healthy adults inhaled 200 microg FP once. Right after inhalation, FP concentration in the esophageal washing fluid was 3.3 microg. On another day, 30 minutes after the same dose of inhaled FP, one FP concentration in the esophageal washing fluid was 0.67 microg (immediately laydown), and another was 0.11 microg (remained standing). This indicates that even though FP dissipates quickly, it remains in the esophagus 30 minutes after inhalation. 2) We observed the process in one patient with high grade (Grade III) esophageal candidiasis. The time of inhalation was changed from just after getting up and just before going to bed to before breakfast and before dinner. Under this regimen, the signs of esophageal candidiasis improved from high to middle grade. Conclusion: If asthmatic patients do not go to sleep immediately after FP inhalation, the remaining FP in the esophagus decreases rapidly, thereby decreasing the risk of esophageal candidiasis. In addition, by changing the FP inhalation times to before breakfast and dinner, the remaining FP in the esophagus is washed away and does not remain in the esophagus. Therefore, this study, which avoided inhalation before going to bed, provides useful information for the prevention and improvement of esophageal candidiasis. PMID:14685037

Candidiasis: predisposing factors, prevention, diagnosis and alternative treatment.  

Science.gov (United States)

Candidiasis is the most common opportunistic yeast infection. Candida species and other microorganisms are involved in this complicated fungal infection, but Candida albicans continues to be the most prevalent. In the past two decades, it has been observed an abnormal overgrowth in the gastrointestinal, urinary and respiratory tracts, not only in immunocompromised patients, but also related to nosocomial infections and even in healthy individuals. There is a widely variety of causal factors that contribute to yeast infection which means that candidiasis is a good example of a multifactorial syndrome. Due to rapid increase in the incidence in these infections, this is the subject of numerous studies. Recently, the focus of attention is the treatment and, above all, the prevention of those complications. The diagnosis of candidiasis could become quite complicated. Prevention is the most effective "treatment," much more than eradication of the yeast with antifungal agents. There are several aspects to consider in the daily routine that can provide a strength protection. However, a therapeutic approach is necessary when the infection is established, and therefore, other alternatives should be explored. This review provides an overview on predisposition factors, prevention and diagnosis of candidiasis, highlighting alternative approaches for candidiasis treatment. PMID:24789109

Hepatosplenic candidiasis after neutropenic phase of acute leukaemia.  

Science.gov (United States)

Hepatosplenic candidiasis following granulocytopenic periods is a relatively recently recognised problem in immunocompromised patients, particularly in those with acute leukaemia. We present three patients in whom diagnosis of hepatosplenic candidiasis was suspected on the basis of ultrasonographic (US), computed tomographic (CT) findings and confirmed by laparoscopy and biopsy of liver lesions. All three patients were successfully treated briefly with amphotericin B, followed by a longer period of fluconazole. In one patient laparotomy and surgical evacuation of abscesses was performed. This condition could be more often recognised by careful follow-up of liver function test, C-reactive protein level, ultrasonography, CT and MRI after recovery from chemotherapy-induced neutropenia.

Science.gov (United States)

Hepatosplenic candidiasis is increasingly observed in patients with a haematological malignancy who have received chemotherapy. A case history is described of a male aged 45 who developed symptoms of hepatosplenic candidiasis caused by Candida tropicalis after treatment for acute myeloid leukaemia. The disease is characterized by persistent fever after recovery of the leukopenia induced by the chemotherapy. Echographic and computer-tomographic examination may reveal abscess patterns specific of Candida in the liver. Treatment consists of amphotericin B intravenously or fluconazole orally. Protracted treatment is frequently required. PMID:8289957

The authors report two cases of splenic and hepatosplenic candidiasis occurring during a protracted neutropenia induced by chemotherapy for acute leukemia (lymphoblastic and myeloblastic respectively). Fungal infection was revealed by persistent or recurrent fever after correction of neutropenia. Diagnosis was suggested by findings at abdominal ultrasonography. It was confirmed by histological analysis which, in the first case, required open liver biopsy. In both cases, lack of improvement of splenic lesions despite treatment with Amphotericin B followed by fluconazole led to splenectomy. Both patients received postoperative anti fungal therapy with Ampho B and at one year's follow up, the patient who had the hepatosplenic candidiasis seems to have recovered. PMID:2369269

One-day therapy for vaginal candidiasis. A review.  

Science.gov (United States)

Shorter courses of therapy have been developed for most antifungal agents used for the treatment of vaginal candidiasis, including clotrimazole, econazole, isoconazole, miconazole, terconazole and fluconazole. A search of the medical literature identified 14 studies that compared single-dose therapy for vaginal candidiasis in nonpregnant women. These studies, conducted according to similar study designs, provided sufficient information to evaluate clinical and mycologic cure rates. There were few significant differences in either the clinical or mycologic cure rates of single-dose therapy, and no one therapy was consistently better than any other.

Hepatosplenic candidiasis in patients with acute leukaemia.  

Science.gov (United States)

A retrospective study of 23 patients with acute leukaemia and hepatosplenic candidiasis (HSC) was conducted to evaluate clinical treatment characteristics in terms of amount and duration of antifungal agents and to assess treatment outcome. Patients were admitted to two major tertiary care centres between 1990 and 1998. The diagnosis of HSC was based on clinical, blood cultures, histologic and imaging studies. Patients were treated with amphotericin B without interruption of the planned chemotherapy regimens. Serial magnetic resonance imaging (MRI) studies were the main tool for following patients' response and activity of the fungal lesions in conjunction with clinical and laboratory parameters. Treatment with amphotericin B was continued until resolution of all clinical symptoms and signs attributable to HSC, obtaining negative blood cultures and the appearance of at least healed lesions on MRI. Amphotericin B was discontinued in four patients because of severe nephrotoxicity (two patients), or continuous fever and persistent fungal lesions on MRI (two patients). Amphotericin B lipid complex (ABELCET) was successfully used as salvage therapy for these refractory patients. Four patients died with evidence of HSC despite treatment and supportive measures. The response rate for treatment of HSC was 82%. The mean total dose of amphotericin B including empirical treatment was 4 g and the median duration of treatment for responding patients was 112 d. The median number of days of anti- fungal treatment before the disappearance of fever was 19 d. Our results confirmed the need for protracted courses of antifungal agents for the successful eradication of HSC. Chemotherapy for the underlying disorder should not be interrupted or delayed in order to treat HSC. PMID:10468858

Candidiasis invasoras en el paciente crítico adulto Invasive candidiasis in critically ill adult patient  

Directory of Open Access Journals (Sweden)

Full Text Available Las infecciones invasoras por Candida spp, representan una patología relevante en los pacientes críticos. Para su oportuno diagnóstico es necesaria una elevada sospecha clinica, tomando en consideración el cuadro clinico y la presencia de factores de riesgo. Pese a la incorporación de nuevos fármacos al arsenal terapéutico durante la última década, mantiene una elevada mortalidad. Las claves para mejorar los desenlaces clínicos en estos pacientes son el empleo de una terapia precoz, eficaz y que permita la cobertura de distintas especies de Candida: C albicans y no albicans. Recientes guías internacionales sugieren la terapia empírica con equinocandinas ante la sospecha de candidiasis invasora en esta población de pacientes. Este grupo de fármacos ha documentado adecuada eficacia clínica y seguridad en estos pacientes. Se espera que la incorporación de nuevas equinocandinas al mercado aminore sus costos y mejore el acceso a este grupo de fármacos.Invasive infections by Candida strains are a relevant pathology in critically ill patients. Candida should be considered where a high risk of infection is present for a critical early diagnosis. Despite the incorporation of new drugs in the therapeutic armamentarium over the last decade, mortality remains high. The key in improving clinical outcomes of these patients are the use of early effective therapies that offer coverage against different strains of Candida: C. albicans and non-albicans. Recent international guidelines suggest empiric therapy with echinocandins in suspected invasive candidiasis in this patient population. This group of drugs adequately documented clinical efficacy and safe use in these patients. The emergence of new echinocandins could improve access to these drugs by reducing their cost.

Hepatosplenic candidiasis--a contraindication to marrow transplantation?  

Science.gov (United States)

To determine whether a prior history of hepatosplenic candidiasis resulted in increased Candida-associated morbidity and mortality after marrow transplant, 15 consecutive patients with biopsy-proven hepatosplenic candidiasis were observed prospectively. All patients received amphotericin B before transplant. Amphotericin B was continued at a dose of 0.5 mg/kg/day from conditioning through marrow engraftment, at which time it was discontinued if computerized tomography (CT) evidence of disease was stable or improved. Patients were observed for progression of candidiasis for the first 100 days after transplant. The amount and duration of antifungal therapy received before transplant varied widely. The majority of patients (73%) had persistently abnormal CT scans before transplant. After transplant, 3 of 15 died (20%) with evidence of fungal disease, although fungal species differed from those diagnosed pretransplant, compared with a historical mortality rate of 90% in posttransplant patients with documented hepatosplenic candida. Comparison CT scans obtained before and after transplant showed improvement in 9 of 15 (60%), complete resolution in 2 of 15 (13%), and none showed progression. We conclude that hepatosplenic candidiasis is not an absolute contraindication to marrow transplant when patients receive amphotericin B therapy before transplant and continue therapy until engraftment is established.

INVASIVE CANDIDIASIS IN NON-HEMATOLOGICAL PATIENTS.  

Directory of Open Access Journals (Sweden)

Full Text Available

Candida is one of the most frequent pathogens isolated in bloodstream infections, and is associated with significant morbidity and mortality. In addition to haematological patients, there are several other populations with a substantial risk of developing invasive candidiasis (IC. These include patients undergoing prolonged hospitalisation with the use of broad-spectrum antibiotics, those fitted with intravascular catheters, admitted to both adult and neonate intensive care units (ICU or gastrointestinal surgery wards and subjects with solid tumours undergoing cytotoxic chemotherapy. As a general rule, every immunocompromised patient might be at risk of Candida infection, including, for example, diabetic patients.

The epidemiology of species responsible for IC has been changing, both at local and worldwide level, shifting from C. albicans to non-albicans species, that can be intrinsically resistant to fluconazole (C. krusei and, to some extent, C. glabrata, difficult to eradicate because of biofilm production (C. parapsilosis or than might acquire resistance to azole during therapy.

Delaying the specific therapy has been shown to increase morbidity and mortality, but traditional microbiological diagnosis is poorly sensitive and slow. Thus, culture-based treatment may result in therapy started too late. In order to reduce the mortality in IC, several management strategies have been developed: prophylaxis, empirical and pre-emptive therapy. Compared to prophylaxis, the latter approaches allow to reduce the use of antifungals by targeting only patients at very high risk of IC. Non-invasive serological markers and scores based on clinical prediction rules such as the presence of risk factors or Candida colonisation, have been developed with the aim of allowing prompt initiation of treatment. Although the use of these diagnostic tools in pre-emptive strategies is promising, the performance and cost-effectiveness should be tested in large trials.

Agents recommended for initial treatment of candidemia in severely ill patients include echinocandins and lipid formulations of amphotericin B, while stable patients without risk factors for azole-resistance might be treated with fluconazole.

Pathology teach and tell disseminated candidiasis in an infant with acute myeloid leukemia without prior chemotherapy.  

Science.gov (United States)

Opportunistic fungal infections are significant problems for neutropenic patients who are undergoing cytotoxic therapy for acute leukemia. Systemic and hepatosplenic candidiasis have been reported in acute leukemic patients who are on chemotherapy. Gastrointestinal tract involvement is a rare phenomenon in disseminated candidiasis, especially in acute leukemia. We report one such rare case of acute myeloid leukemia in an infant who died of disseminated candidiasis with gastrointestinal tract involvement prior to the institution of chemotherapy.

A randomized cross-over clinical and endoscopic evaluation of 85 Ugandan patients showed that esophageal candidiasis in AIDS patients with oral candidiasis could be managed without endoscopy and biopsies. Oral lesions, especially when accompanied by esophageal symptoms, were sufficient for diagnosis. Miconazole was more effective than nystatin in treating esophageal candidiasis and could be a valid alternative to more expensive azolic drugs in developing countries.

Hepatosplenic candidiasis is also called chronic disseminated candidiasis and usually seen in patients with hematologic malignancies who have just recovered from an episode of neutropenia. Gastric candidiasis most commonly present as a mucosal lesion such as an ulcer or erosions, but other gastric lesion is very rare. We experienced a case of gastric candidiasis which presented as gastric subepithelial mass in a 60-year old woman who had undergone the 2nd consolidation chemotherapy due to acute myeloid leukemia. The pathologic diagnosis was confirmed by fine needle aspiration of the gastric subepithelial mass under the guidance of endoscopic ultrasonography. PMID:19158470

Oral candidiasis-adhesion of non-albicans Candida species  

Directory of Open Access Journals (Sweden)

Full Text Available Oral candidiasis is an opportunistic infection caused primarily by Candida albicans. However, in recent years, species of non-albicans Candida have been implicated more frequently in mucosal infection. Candida species usually reside as commensal organisms and are part of normal oral microflora. Determining exactly how transformation from commensal to pathogen takes place and how it can be prevented is continuous challenge for clinical doctors. Candidal adherence to mucosal surfaces is considered as a critical initial step in the pathogenesis of oral candidiasis. Acrylic dentures, acting as reservoirs, play an important role in increasing the risk from Candida colonisation. Thus, this review discusses what is currently known about the adhesion of non-albicans Candida species of oral origin to buccal epithelial cells and denture acrylics.

Lamisil Versus Clotrimazole in the Treatment of Vulvovaginal Candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives: Vaginal candidiasis is a common disease in women during their lifetime and occurs in diabetes patients, during pregnancy and oral contraceptives users. Although several antifungals are routinely used for treatment; however, vaginal candidiasis is a challenge for patients and gynecologists. The aim of the present study was to evaluate terbinafine (Lamisil on Candida vaginitis versus clotrimazole.Materials and Methods: In the present study women suspected to have vulvovaginal candidiasis were sampled and disease confirmed using direct smear and culture examination from vaginal discharge. Then, patients were randomly divided into two groups, the first group (32 cases was treated with clotrimazole and the next (25 cases with Lamisil. All patients were followed-up to three weeks of treatment and therapeutic effects of both antifungal were compared.Results: Our results shows that 12 (37.5% patients were completely treated with clotrimazole during two weeks and, 6(18.8% patients did not respond to drugs and were refereed for fluconazole therapy. Fourteen (43.8% patients showed moderate response and clotrimazole therapy was extended for one more week. When Lamisil was administrated, 19 (76.0% patients were completely treated with Lamisil in two weeks, and 1 (4.0% of the patients did not respond to the drug and was refereed for fluconazole therapy. Five (20.0% of our patients showed moderate response and Lamisil therapy was extended for one more week.Conclusion: Our results show that vaginal cream, 1% Lamisil, could be suggested as a first-line treatment in vulvovaginal candidiasis.

Micafungin in the treatment of invasive candidiasis and invasive aspergillosis  

Directory of Open Access Journals (Sweden)

Full Text Available Nathan P Wiederhold1, Jason M Cota2, Christopher R Frei11University of Texas at Austin College of Pharmacy, Austin, Texas, USA; 2University of the Incarnate Word Feik School of Pharmacy, San Antonio, Texas, USAAbstract: Micafungin is an echinocandin antifungal agent available for clinical use in Japan, Europe, and the United States. Through inhibition of ?-1,3-glucan production, an essential component of the fungal cell wall, micafungin exhibits potent antifungal activity against key pathogenic fungi, including Candida and Aspergillus species, while contributing minimal toxicity to mammalian cells. This activity is maintained against polyene and azole-resistant isolates. Pharmacokinetic and pharmacodynamic studies have demonstrated linear kinetics both in adults and children with concentration-dependent activity observed both in vitro and in vivo. Dosage escalation studies have also demonstrated that doses much higher than those currently recommended may be administered without serious adverse effects. Clinically, micafungin has been shown to be efficacious for the treatment of invasive candidiasis and invasive aspergillosis. Furthermore, the clinical effectiveness of micafungin against these infections occurs without the drug interactions that occur with the azoles and the nephrotoxicity observed with amphotericin B formulations. This review will focus on the pharmacology, clinical microbiology, mechanisms of resistance, safety, and clinical efficacy of micafungin in the treatment of invasive candidiasis and invasive aspergillosis.Keywords: micafungin, echinocandin, Candida, Aspergillus, invasive candidiasis, invasive aspergillosis

Sensitivity of Candida albicans from patients with chronic oral candidiasis.  

Science.gov (United States)

Many patients with oral candidiasis respond very slowly or not at all to therapy with amphotericin. Strains of Candida albicans were collected from 17 patients clinically resistant and from 15 who responded to a normal course of amphotericin treatment. Minimal inhibitory concentrations (MIC) determined on diagnostic sensitivity test agar plates gave values of: amphotericin 0-5 mg/l; nystatin 50 i.u./ml; chlorhexidine 12.5 mg/l. No clear MIC could be determined with plates containing miconazole. No difference was noted in MIC values between the 2 groups of patients. Tube-dilution tests in Sabouraud's broth gave MIC values of: amphotericin 0.25 mg/l; nystatin 12.5 i.u./ml; chlorhexidine 1.5 mg/l; miconazole 8-32 mg/l; ketonazole 64 mg/l. Persistence of oral candidiasis is not an indication of infection with resistant organisms. Despite difficulties in in vitro sensitivity testing of miconazole a clinical trial of the drug for treating oral candidiasis is indicated. PMID:392486

[Hepatosplenic candidiasis in acute non-lymphocytic leukemia].  

Science.gov (United States)

Eleven patients with acute non-lymphocytic leukemia developed hepatosplenic candidiasis following the termination of chemotherapy. Five who did not receive amphoteicin B (AMPH) died of liver failure, whereas the other six who received AMPH and/or miconazole or fluconazole were cured. The features of hepatosplenic candidiasis included prolonged high fever not responsive to antibiotics and hepatomegaly with right-sided hypochondrial pain developing after severe neutropenia. Even if the neutropenia recovered, these symptoms did not subside. In addition, elevation of the serum alkaline phosphatase and total bilirubin levels were observed at onset. CT scan revealed multiple low-density areas of varying size that showed no contrast enhancement. Ultrasonography also demonstrated hypoechoic or hyperechoic lesions, and a so-called "target sign appearance" in the liver and spleen. The clinical diagnosis for hepatosplenic candidiasis is not so difficult because of the uniform symptoms, signs and laboratory abnormalities. The importance of the early administration of antifungal agents to obtain a cure is discussed in this article. PMID:1919111

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.Keywords: oropharyngeal candidiasis, esophageal candidiasis, HAART, antifungal agents, HIV, AIDS

Critically ill patients in the intensive care unit (ICU) are at increased risk of encountering bloodstream infections (BSIs) with Candida spp., associated with an elevated crude mortality rate. This supports the significance of early detection of infection and identification of the most effective management approach. A review of the various antifungal treatments and an evaluation of the diverse management approaches for invasive candidiasis in critically ill patients is necessary for guiding evidence-based decision-making. Different early detection schemes for invasive candidiasis are well documented in the literature. Other than the common use of blood cultures, new methods entail the use of risk prediction scores and biomarker tests. Regarding management strategies, different options are currently supported. These include prophylaxis, empirical therapy, pre-emptive therapy, and treatment of culture-documented infections. The choice of treatment is greatly dependent on several factors related to the patient and/or to the surrounding environment. Attention needs to be given to previous exposure to azoles, epidemiological data on dominant Candida spp. in local ICUs, severity of illness and associated morbidities. This paper summarises the most recent literature as well as the guidelines issued by the Infectious Diseases Society of America. The objective is to identify the best diagnosis and management approaches for serious Candida infections in critically ill patients. In addition, this article addresses an important aspect associated with managing candidaemia in critically ill patients pertaining to the decision for intravenous catheter removal. PMID:23664579

The diagnosis of hepatosplenic candidiasis by DNA analysis of tissue biopsy and serum.  

Science.gov (United States)

Hepatosplenic candidiasis is traditionally diagnosed by blood culture, magnetic resonance imaging (MRI), and histological analysis. The limitations of these methods include: low sensitivity (blood culture) and failure to isolate the organism (MRI/histology). This report describes a case of hepatosplenic candidiasis diagnosed by simultaneous polymerase chain reaction (PCR) analysis of liver biopsy and serum. PCR of biopsy and/or serum may offer a sensitive and specific diagnostic test for hepatosplenic candidiasis. Candida species can be identified, which helps guide antifungal chemotherapy, an important aspect in this difficult to treat infection. PMID:15220373

Comparison between Fluconazole with Oral Protexin Combination and Fluconazole in the Treatment of Vulvovaginal Candidiasis.  

Science.gov (United States)

Background. According to the limited studies reporting new treatments for vulvovaginal candidiasis, this study was designed to compare the combination of fluconazole and oral protexin with fluconazole in the treatment of vulvovaginal candidiasis. Methods. A double-blind clinical trial was conducted, involving 90 women who were referred to the gynecology clinic. Vulvovaginal candidiasis was diagnosed with itching, cheesy vaginal discharge, and any one of the following: dysuria, pH protexin and fluconazole-placebo, were equally effective in reduction of complaints and symptoms, but fluconazole-oral protexin combination elicited a better therapeutic response (?(2) = 0.01, P = 6.7). In addition, fluconazole-oral protexin combination treatment demonstrated better recovery time (t = -2.04, P = 0.04). Conclusion. This study demonstrated that complementary treatment with probiotic Lactobacillus increased the efficacy of fluconazole in treatment of vulvovaginal candidiasis. Further research is recommended.

Hepatosplenic candidiasis in non-neutropenic patients: a case report and literature survey.  

Science.gov (United States)

Hepatosplenic candidiasis is an increasingly recognized infectious complication in patients who have an underlying malignancy and/or have chemotherapy-induced neutropenia. Only six cases of hepatosplenic candidiasis in non-neutropenic patients have been described to date, to which we add a seventh. Our patient had many of the classically described manifestations of hepatosplenic candidiasis, and responded well to therapy with amphotericin B. Retrospective comparative analysis of cases of hepatosplenic candidiasis reveals that non-neutropenic patients seem to respond well to medical therapy that is less intensive than that given to neutropenic subjects (total dosage of amphotericin B 0.84 g vs. 2.70 g, respectively) and tend to have a better prognosis (mortality rate 33% vs. 44%, respectively).

Cell Adhesion Molecule and Lymphocyte Activation Marker Expression during Experimental Vaginal Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Cell-mediated immunity by Th1-type CD4+ T cells is the predominant host defense mechanism against mucosal candidiasis. However, studies using an estrogen-dependent murine model of vaginal candidiasis have demonstrated little to no change in resident vaginal T cells during infection and no systemic T-cell infiltration despite the presence of Candida-specific systemic Th1-type responses in infected mice. The present study was designed to further investigate these observations by characterizing ...

Successful peritransplant therapy in children with active hepatosplenic candidiasis.  

Science.gov (United States)

Two pediatric leukemic patients with hepatosplenic candidiasis during multidrug antileukemic chemotherapy successfully underwent bone marrow transplantation (BMT) after aggressive antifungal chemotherapy employing fluconazole and amphotericin B with or without splenectomy. One patient received allogeneic marrow graft and the other received an autologous graft. One patient has been disease-free for more than 21 months after BMT without any recurrence of Candida infection. The other patient showed tentative reactivation of hepatic lesions just after BMT by CT scanning, but these lesions disappeared again by continuous administration of the antifungal agents. The second patient died of leukemia relapse without recurrence of fungal infection. Our cases indicate the possibility of successful BMT once a fungal infection is well controlled by antifungal chemotherapy and surgical resection. PMID:8018905

Adjuvant corticosteroid therapy in hepatosplenic candidiasis-related iris.  

Science.gov (United States)

Candida infections are the most frequent infections in neutropenic patients. Hepatosplenic candidiasis (HSC) is a part of disseminated Candida infection that occurs most commonly in patients with hematologic malignancies treated with chemotherapy and requires protracted antifungal therapy. During invasive mycosis with rapid resolution of immunosuppression, immune reconstitution inflammatory syndrome (IRIS) which mimics treatment failure, drug toxicity or breakthrough infections may occur. Manifestation period, histopathologic findings and favorable effect of steroids to its inflammatory symptoms strongly suggest that HSC belongs to the invasive fungal infection induced IRIS. We present a child with B cell-acute lymphoblastic leukemia who developed HSC and addition of corticosteroid therapy to antifungal treatment achieved rapid resolution of the clinical symptoms and laboratory findings.

Hepatosplenic candidiasis in patients with acute leukemia: increasingly encountered complication.  

Science.gov (United States)

Hepatosplenic candidiasis (HSC) is an increasingly recognized complication of treatment with chemotherapeutic agents. The true incidence of HSC is not known, but most experts agree that there has been an increase in its occurrence during the past 15 years, and most of them attribute this rise to the use of more intensive chemotherapeutic regimens in the treatment of hematologic malignancies, especially, acute leukemia. The most recognizable risk factor predisposing for this complication is prolonged neutropenia. The diagnosis of HS requires high clinical suspicion and expertise in the interpretation of the histopathologic and radiologic data. Most importantly, treatment of the condition requires prolonged administration of antifungal drugs and continuous monitoring using combination of clinical, laboratory and radiologic tests in order to ascertain eradication of the infection. In this minireview I will present a summary of the data available in the literature in combination with our prospective experience in the investigation of HSC. PMID:10216488

Treatment of hepatosplenic candidiasis with liposomal-amphotericin B.  

Science.gov (United States)

Nine patients with hematologic malignancies developed fungal infections, predominantly involving the liver and spleen. Eight patients had biopsy-documented progressive candidiasis and one had an unclassified fungus. The patients were treated with liposomal-amphotericin B (L-AmpB) after their fungal infection progressed during treatment with standard intravenous (IV) AmpB (Fungizone; E. R. Squibb & Son, Princeton, NJ) and/or other antifungals. Eight patients (88.8%) were cured of their fungal infection, and one showed improvement after treatment. Minor acute toxicity and no chronic toxicity were associated with the administration of L-AmpB. L-AmpB is a safe and effective therapeutic method for treating fungal infections that have invaded the liver and spleen even when they are refractory to conventional anti-fungal therapy.

Management of oropharyngeal candidiasis with localized oral miconazole therapy: efficacy, safety, and patient acceptability  

Directory of Open Access Journals (Sweden)

Full Text Available Curtis D Collins1, Sarah Cookinham2, Jeannina Smith21Department of Pharmacy Services, 2Department of Medicine, Division of Infectious Disease, University of Michigan Health System, Ann Arbor, MI, USAAbstract: Oropharyngeal candidiasis is a very common localized infection of the mucus membranes of the oropharynx that is most commonly caused by the patient's own commensal Candida albicans. It is the most common opportunistic infection affecting patients with the human immunodeficiency virus (HIV and is also quite common in patients with hematological malignancies. Effective treatment options are of high importance given the worldwide incidence of these disease states and the potential for development of oropharyngeal candidiasis in these patients. Various systemic and topical treatment options for patients with oropharyngeal candidiasis have existed for many years. Miconazole buccal tablets have recently been approved by the US Food and Drug Administration for the treatment of oropharyngeal candidiasis. Clinical trials have demonstrated noninferiority in the treatment of oropharyngeal candidiasis when compared with clotrimazole troches in patients with HIV and against miconazole gel in patients with head and neck cancer. Miconazole buccal tablets exhibit few drug interactions because of low systemic absorption and are generally well tolerated with a safety profile similar to comparators. The once-daily dosing schedule may improve patient adherence compared with topical alternatives; however, the cost of therapy may be a barrier for some patients and should be considered by prescribers compared with alternative treatments.Keywords: esophageal candidiasis, miconazole, antifungal agents

Prevalence and epidemiological characteristics of vaginal candidiasis in the UAE.  

Science.gov (United States)

Vaginal candidiasis (VC) continues to be a health problem to women worldwide. Although the majority of VC cases are caused by Candida albicans (C. albicans), non-albicans Candida spp. like C. glabrata and C. tropicalis are emerging as important and potentially resistant opportunistic agents of VC. The objective of this study was to evaluate the prevalence and epidemiology of VC in the UAE through retrospective analysis of pertinent data compiled by the microbiology and infection control unit at Latifa Hospital, Dubai between 2005 and 2011. The incidence of VC significantly increased from 10.76% in 2005 to 17.61% in 2011; average prevalence was 13.88%. C. albicans occurred at a frequency of 83.02%, C. glabrata at 16.5% and C. tropicalis at 1.2%. A single C. dubliniensis isolate was identified in the sample population. The percentage of C. albicans significantly decreased from 83.02% in the sample population as a whole to 60.8% in subjects over 45 years of age (P < 0.01) and that of C. glabrata, C. tropicalis and C. krusei significantly increased from 13.88%, 0.9% and 0.03% to 29.7%, 6.7% and 1.4% (P < 0.05) respectively. The incidence of VC in the UAE is on the rise and the frequency of non-albicans Candida spp. is noticeably increasing especially in postmenopausal women. PMID:24102778

Treatment and prophylaxis of invasive candidiasis with anidulafungin, caspofungin and micafungin - review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Working by a distinct cell wall-specific mechanism of action, the echinocandin class of antifungals has substantially expanded the range of available treatments for invasive Candida infections. Anidulafungin, caspofungin and micafungin were investigated versus drugs from earlier antifungal classes in large clinical trials that demonstrated their excellent clinical and microbiological efficacy in the primary treatment of invasive candidiasis. Therefore, and supported by a number of favourable pharmacological characteristics, the echinocandins rapidly became established in guidelines and clinical practice as primary treatment options for moderately to severely ill patients with invasive candidiasis. This article reviews the relevant clinical evidence that forms the basis for the use of echinocandins in the management of invasive candidiasis, and discusses their current role in the context of recent guideline recommendations and treatment optimization strategies.

Hepatic candidiasis in cancer patients: the evolving picture of the syndrome.  

Science.gov (United States)

Focal hepatosplenic candidiasis has been recognized with increasing frequency in recent years. We reviewed the cases of eight patients seen between 1982 and 1985, and information on 60 patients whose cases have been reported in the world literature. The characteristics of focal hepatosplenic candidiasis include persistent fever in a neutropenic patient whose leukocyte count is returning to normal, often coupled with abdominal pain; an elevated alkaline phosphatase level; and less commonly, rebound leukocytosis. The characteristic "bull's eye" lesions seen with hepatic ultrasound examination or computed tomography generally are not detectable until neutrophil recovery has occurred. Diagnosis can be established only by biopsy evidence of yeasts or pseudohyphae in the granulomatous lesions. Cultures are frequently negative, however, especially in patients who have been pretreated with antifungal agents. We review the evolving nature of hepatosplenic candidiasis, focusing on diagnosis and treatment. PMID:3276268

Systemic Candidiasis with Multiple Abscesses After Transurethral Resection of the Prostate Gland  

Directory of Open Access Journals (Sweden)

Full Text Available SUMMARY. The rare case is presented of a patient who developed multiple abscesses from Candida albicans after transurethral resection of the prostate gland for benign prostatic hyperplasia. The abscesses developed in the urogenital system, the anorectal region and the lungs, and also subcutaneously. They were treated both surgically and with medication. Solitary abscess as a manifestation of candidiasis is well documented, but to the best of the authors’ knowledge this is the first report of multiple, synchronous abscesses in different systems in a patient with systemic candidiasis.

Lack of circulating Candida mannoprotein antigen in patients with focal hepatosplenic candidiasis.  

Science.gov (United States)

The significance of Candida mannoprotein serum detection in 15 patients with haematological malignancies and proven (six cases) or probable (nine cases) hepatosplenic candidiasis was retrospectively evaluated. Circulating mannoprotein antigen was detected in three of six and in one of two serum samples from two patients with probable infection. The antigen was not detected in 38 serum samples of 13 (87%) patients. Thus, in contrast to other deep-seated Candida infections, mannoprotein is infrequently detectable during focal hepatosplenic candidiasis and does not appear to be of diagnostic value. PMID:14729929

Application of enzyme-immunohistochemistry for the diagnosis of aspergillosis, candidiasis, and zygomycosis in three lovebirds.  

Science.gov (United States)

Aspergillosis, candidiasis, and zygomycosis were diagnosed in tissues from three lovebirds (Agapornis roseicollis) using indirect enzyme-immunohistochemical techniques. In these techniques, the first antibody was raised against fungal antigen. A second antibody, which was raised in another animal species, was added to link the first antibody to enzyme-immunocomplexes. The reactivity of specific monoclonal and polyclonal antibodies was visualized by immunoreactivity of alkaline phosphatase anti-alkaline phosphatase and peroxidase anti-peroxidase immunocomplexes. All three birds examined had dermal candidiasis. In addition, one of the birds was diagnosed with concomitant acute ocular aspergillosis, and another bird was diagnosed with chronic zygomycotic myocarditis. PMID:8257396

Hepatosplenic candidiasis in patients with acute leukemia: incidence and prognostic implications.  

Science.gov (United States)

We studied the incidence among, risk factors for, and survival of adult patients with acute leukemia and hepatosplenic candidiasis during the period 1980 to 1993. Of 562 adult patients with acute leukemia, 38 (6.8%) had hepatosplenic candidiasis. The incidence of infection increased fivefold during the study period. The incidence was higher among patients with acute lymphatic leukemia (11.3%) than among those with acute myeloid leukemia (5.1%) (P = .01). The median survival was 9.5 months, and by the end of follow-up, 74% of patients had died. Patients whose leukemia was in remission before the last cytotoxic treatment preceding hepatosplenic candidiasis survived longer than did patients with newly diagnosed or refractory or relapsed leukemia (P = .0065). Eleven patients died within 3 months after the diagnosis of the infection: 7 of 16 with newly diagnosed leukemia, 4 of 10 with refractory or relapsed leukemia, and 0 of 12 with leukemia in remission (P = .028). In all of the patients who died within 3 months, infection was found at autopsy. In conclusion, the incidence of hepatosplenic candidiasis has significantly increased since 1980, and the outcome for patients with this infection is related to the stage of leukemia. PMID:9114188

Adjuvant corticosteroid therapy in 2 children with hepatosplenic candidiasis-related IRIS.  

Science.gov (United States)

First described in HIV-infected patients who recently initiated highly active antiretroviral therapy, the immune reconstitution inflammatory syndrome (IRIS) is best characterized as a collection of inflammatory disorders triggered by rapid resolution of immunosuppression. Treatment of IRIS is a clinical challenge due to the variety of clinical presentations and the presence of multiple pathogens capable of causing the syndrome. Hepatosplenic candidiasis, an uncommon form of invasive Candida species infection, was recently suggested to belong to the spectrum of fungus-related IRIS. We report 2 cases of probable hepatosplenic candidiasis according to the guidelines of the European Organization for Research and Treatment of Cancer and the Mycosis Study Group, occurring in pediatric patients with acute leukemia during rapid neutrophil recovery after cytotoxic chemotherapy. In both cases, abdominal computed tomography scan revealed multiple hepatic micronodules, and liver biopsy showed nonspecific granulomatous lesions. Hepatosplenic candidiasis symptoms (fever, nausea and vomiting, abdominal pain) resolved within 2 days after adjunction of corticosteroid therapy to antifungal treatment. Inflammatory markers and related radiologic abnormalities decreased or disappeared within 1 month. Recovery of neutrophil count in a context of hepatosplenic candidiasis may result in a heightened inflammatory response. Corticosteroid therapy in this setting is associated with prompt resolution of the symptoms. PMID:19770685

Histopathological Characteristics of Experimental Candida tropicalis Induced Acute Systemic Candidiasis in BALB/c Mice  

Directory of Open Access Journals (Sweden)

Full Text Available Systemic candidiasis caused by Candida tropicalis is potentially fatal in human but studies relating the histological characteristics with C. tropicalis induced acute systemic candidiasis are few in number. Hence, this study was undertaken to establish and to characterize the distinctive histopathological features of acute systemic candidiasis by varying the inoculum size of C. tropicalis injected in mice. Thirty BALB/c mice were divided into three groups and were injected with either 1x105 or 1x107 C. tropicalis cells. On observation, the histopathological findings and the fungal burden load following intravenous injection were similar to the previously reported mouse model for Candida albicans. Viable yeast cells in the kidneys reached approximately 22.5 log10 cfu g-1 at day 7 post-infection. Compared with the control group, the infected mice group developed acute pyelonephritis characterized by infiltration of large masses of neutrophils within the infected nephrons. Similarly, foci of acute renal inflammation within the kidney were more pronounced when the C. tropicalis inoculum was increased. Interestingly, we also observed infection of mice with a higher inoculum of C. tropicalis resulted in more severe invasiveness. In conclusion, these results suggest that the BALB/c mouse is highly susceptible to C. tropicalis dissemination and represents a significant model system of acute systemic candidiasis.

CD8 T-cells and E-cadherin in host responses against oropharyngeal candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Oropharyngeal candidiasis (OPC) is the most common oral infection in HIV+ persons. Previous studies suggest a role for CD8+ T-cells against OPC when CD4+ T-cells are lost, but enhanced susceptibility to infection occurs when CD8+ T-cell migration is inhibited by reduced tissue E-cadherin.

Addition of Caspofungin to Fluconazole Does Not Improve Outcome in Murine Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Caspofungin is a potent antifungal inhibiting glucan synthesis in Candida species. However, caspofungin is not 100% curative in candidiasis. Therefore, we evaluated combinations of fluconazole with caspofungin for murine candidemia. We could not show any benefit of combined therapy over individual antifungal drugs.

Evaluation of Prevalence of Oral Candidiasis in Patients Using Complete Denture Wears  

Directory of Open Access Journals (Sweden)

Full Text Available Denture stomatotos os a common problem of the denture wears, and its etiology is not clear from the literatures. Some studies show that the aetiology is candida albicans, while other reports point out the other agents including candida albicans. The present study was designed to evaluate the prevalence of oral candidiasis in patients using complete denture with different datas. 50 subjects all wearing complete denture participated in this study. The palatal mucosa was swabbed and swabs were cultured in Sabourauds medium containing 0.005% chloramphenicol then cultures were tested with common mycological lab tests. In 80% of patients oral candidiasis have been diagnosed. In the investigation a direct relation between the oral candidiasis and removal of denture at night, denture cleanliness, presence of any suction and symptoms of denture stomatitis was shown. No relation between the oral candidiasis and sex, smoking habit, succeptible disease, angular cheilitis; the recent condition of denture and the retention of denture were found. The findings of our investigation indicates that candida albicans is the causative agent of denture stomatitis while other factors such as denture cleanliness, removal of denture at night and presence of any suction may be considered as well.

New US and CT patterns of hepatic and spienic candidiasis in immunocompromised patients  

International Nuclear Information System (INIS)

Nine immunocompromised cancer patients with tissue-proved candidiasis underwent a total of eight serial abdominal US studies and 53 CT examinations. Four US patterns of hepatic and splenic candidiasis were recognized. Type 1 was a ''wheel within a wheel'', or a central hypoechoic nidus surrounded by a dense band, in turn surronded by a rim of hypoechoic tissue. Type 2 was the classic ''bull's eye'' lesion. Type 3, the most common, was a uniformly hypoechoic lesion, 1-4 cm in diameter. Type 4 was a small, dense, echogenic focus with no surrounding lucency and varying amounts of posterior shadowing. Types 1,2 and 3 were seen early in infection; types 3 and 4 were present later. Lesion types 2,3 and 4 were also identified on CT scans. In addition, periportal linear areas of increased attenuation, possibly calcified, were identified on follow-up, non-contrast-enhanced CT. Some abscesses were better seen on non-contrast-enhanced CT scans, while others became visible only after iodinated contrast medium was administered intravenously. Although lesions not seen on US were often seen on CT, the opposite was also true. In two cases pathologic proof of candidiasis was established even when all imaging studies were negative. Patients should be studied by US and by CT before and after contrast agent administration for maximum sensitivity. Even when both US and CT are negative, if there is a strong clinical suspicion of candidiasis, open biopsy is recommended

Oral Candidiasis in children and adolescents with cancer: Identification of Candida spp  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: English Abstract in english Oral candidiasis represents a serious problem for children with cancer. The mortality rate of this infection has increased due to fungal septicemia, associated with a primary buccal infection. Objective: Identify the Candida spp. in buccal lesions of patients with cancer, establish the predominant s [...] pecies and correlate them to age and sex of the patient, clinical presentation, type of neoplasic disease and cytostatic therapy received. Study design: 62 patients, between 0-16 years, were investigated in a cross sectional study. Sample inclusion criteria: Patients with malignant neoplasic disease that were receiving cytostatic treatment and had suspicious lesions of oral candidiasis. Patients with antifungal therapy, active caries, calculus or intraoral appliances were excluded. A clinical evaluation was carried out. The lesion sample was taken and studied by direct exam and culture in CHROMagar-Candida and Sabouraud-Dextrose Agar with chloramphenicol. The identification of the isolated yeast was done by the filamentation test, carbohydrate fermentation and assimilation. Results: Most of the cases (69.35%) were positive to oral candidiasis, C. albicans was the most frequent species found, followed by C. parapsilosis (14.89%), C. tropicalis (12.77%), C. krusei (4.26%), C. glabrata (2.13%) and C. lusitaniae (2.13 %). In some cases more than one specie were isolated (9.30%). The most frequent location of the lesion was in the tongue (72.70%). The pseudomembranous candidiasis was the most frequent clinical presentation found (78.71%). There were not significant statistically differences with regard to sex and age of the patient, type of neoplasic disease and cytostatic agent received. Conclusion: The results suggest that oral candidiasis is a frequent complication in the pediatric oncological population, being C. albicans the main etiological agent, however, there is an important participation of other Candida species.

High dose cytosine arabinoside is a major risk factor for the development of hepatosplenic candidiasis in patients with leukemia.  

Science.gov (United States)

A retrospective study of hepatosplenic candidiasis in patients with acute leukemia from a single centre was performed. The significance of age, sex, type of leukemia, dose of cytosine arabinoside (Ara-C), duration of neutropenia, steroid use and period of therapeutic antibiotics in the development of hepatosplenic candidiasis was analyzed, using logistic regression analysis. Nine of 51 patients had hepatosplenic candidiasis. Ara-C use was highly associated with the development of hepatosplenic candidiasis (p = 0.001); with a high association with a higher dose (p < 0.0001). On the basis of these results consideration should be given to further trial of antifungal prophylaxis for patients receiving high dose Ara-C. PMID:9477128

DETECTION OF ANTIBODIES TO CANDIDA ALBICANS GERM TUBE BY IMMUNOFLUORESCENCE IN IMMUNOSUPPRESSED MICE WITH EXPERIMENTAL SYSTEMIC CANDIDIASIS  

Directory of Open Access Journals (Sweden)

Full Text Available "nThe increasing incidence of systemic candidiasis, which parallels the use of invasive and immunosuppressive medical procedures, necessitates development of rapid and cost effective tests for diagnosis of systemic candidiasis. Therefore in this study 85 mice were first immunosuppressed by cyclophosphamide and then infected by Candida albicans NCPF 3153. Other 85 mice were employed as control. The case and control mice were bled and then autopsied. Hearts and kidneys were checked by direct, histopathological and cultural examination for systemic candidiasis. The 85 sera from histological proven cases and 85 control mice were adsorbed with heat killed blastospores of same strain of C. albicans. Anti-Candida albicans germ tube antibodies were detected by indirect immunofluorescence assay for diagnosis of invasive candidiasis in case and control mice. In addition, sera from 35 mice with proven cryptococcosis were also tested. While 84 mice with proven systemic candidiasis (100% had anti-germ tube antibodies, these antibodies were absent in all controls and mice with cryptococcosis. The specificity was 100%, indicating a high degree of discrimination was possible between systemic candidiasis and cryptococcosis in the mice studied. It must be concluded that anti-germ tube responses did not appear to be significantly reduced in immunocompromised mice.

Hepatosplenic candidiasis: an overlooked cause of prolonged fever during recovery from an episode of neutropenia.  

Science.gov (United States)

Two cases of hepatosplenic candidiasis (HSC) are reported occurring after protracted episodes of neutropenia, induced by chemotherapy for acute leukemia in one case and drug hypersensitivity in the other. The disease presented with persistent or recurrent fever after correction of the neutropenia and with splenomegaly. The alkaline phosphatases were elevated. The diagnosis was strongly suggested by abdominal ultrasonography, CT scan and MRI, which showed multiple hepatosplenic defects. It was confirmed by serologic tests for candidiasis, the presence, in 1 case, of circulating candida antigens, and the rapid response to amphotericin B. The diagnosis of HSC should be considered in patients with persistent fever after an episode of neutropenia. Ideally, histologic confirmation is desirable, but this is often obtainable only by open liver biopsy, an aggressive procedure in such patients. Failing this, our 2 cases stress the diagnostic value of noninvasive imaging techniques, serological testing (in particular the discovery of circulating candida antigens) and the response to amphotericin B.

Hepatosplenic candidiasis in children with cancer. Three cases in leukemic children and a literature review.  

Science.gov (United States)

Three children with acute leukemia presented with prolonged fever and neutropenia after cytostatic therapy, which was followed by abdominal pain, hepatomegaly, and hepatic dysfunction with raised serum alkaline phosphatase. Abdominal CT scan and ultrasound demonstrated multiple small lesions compatible with the hepatosplenic candidiasis syndrome. Liver biopsies showed microabscesses with a granulomatous appearance, but evidence of yeasts and pseudohyphae was present in 1 case only. Cultures were negative. Treatment with amphotericin B and 5-fluorocytosine was successful in two children. At autopsy, one child had signs of active infection. We reviewed the literature on 27 children with hepatosplenic candidiasis. Abdominal symptomatology and prolonged fever, despite antibiotic therapy, in a patient with previous or present neutropenia after cytotoxic exposure, should lead to a careful evaluation, including noninvasive imaging studies, open liver biopsy, and prompt aggressive antifungal treatment, the response to which requires close follow-up.

Sertaconazole: an antifungal agent for the topical treatment of superficial candidiasis.  

Science.gov (United States)

Sertaconazole is a useful antifungal agent against mycoses of the skin and mucosa, such as cutaneous, genital and oral candidiasis and tinea pedis. Its antifungal activity is due to inhibition of the ergosterol biosynthesis and disruption of the cell wall. At higher concentrations, sertaconazole is able to bind to nonsterol lipids of the fungal cell wall, increasing the permeability and the subsequent death of fungal cells. Fungistatic and fungicidal activities on Candida are dose-dependent. The antifungal spectrum of sertaconazole includes deramophytes, Candida, Cryptococcus, Malassezia and also Aspergillus, Scedosporium and Scopulariopsis. Sertaconazole also shows an antimicrobial activity against streptococci, staphylococci and protozoa (Trichomonas). In clinical trials including patients with vulvovaginal candidiasis, a single dose of sertaconazole produced a higher cure rate compared with other topical azoles such as econazole and clotrimazole, in shorter periods. Sertaconazole has shown an anti-inflammatory effect that is very useful for the relief of unpleasant symptoms. PMID:23566144

Development of Film Dosage Forms Containing Miconazole for the Treatment of Oral Candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Film dosage forms (FDs containing miconazole (MCZ for the treatment of oral candidiasis were prepared using water-soluble polysaccharides, and the dissolution profiles of MCZ from the FDs were investigated. In addition, the forms were modified by the addition of a surface active agent to accelerate the drug dissolution rate. Circular films incorporating MCZ were obtained using each polysaccharide. Most FDs were easy to handle and resistant to tearing. No diffraction peaks were observed in the X-ray diffractograms of FDs. FDs prepared with sodium alginate or pullulan immediately swelled and disintegrated in aqueous medium, whereas MCZ incorporated in the FD gradually dissolved. A marked acceleration in the MCZ dissolution rate was observed when FD was prepared with polysaccharide containing a surfactant. These results confirmed that modified FDs are useful for treating localized conditions in the oral cavity, such as oral candidiasis, and that FDs can simplify the administration of drugs to patients.

The autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy or autoimmune polyglandular syndrome type 1.  

Science.gov (United States)

Autoimmune polyglandular syndromes are rare autoimmune endocrinopathies that are associated with nonendocrine autoimmunopathies. Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), also named autoimmune polyglandular syndrome type 1 (APS-1), is distinguished from autoimmune polyglandular syndrome 2 (APS-2). Major disease components of APECED are adrenal insufficiency, hypoparathyroidism, and candidiasis. The diagnosis is established by the presence of two out of the three components. Minor clinical features include autoimmune hepatitis, which occurs in up to 20% of APECED patients, and ranges from a mild to a fulminant course. The disease mostly affects juvenile patients from Sardegna, Italy, Finland, and Iran (Iranian Jews), but it also occurs in other ethnic groups. The AIRE gene responsible for APECED is expressed in cells involved in induction and maintenance of immune tolerance. Genetic alterations of the single gene are associated with APECED. Because a specific therapy is not currently available, treatment consists of hormone replacement and caring for clinical symptoms. PMID:19676003

Mucocutaneous candidiasis and autoimmunity against cytokines in APECED and thymoma patients: clinical and pathogenetic implications.  

Science.gov (United States)

Much has been learnt about the mechanisms of thymic self-tolerance induction from work on both the rare autosomal recessive disease autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) and the autoimmune regulator (AIRE) protein mutated in this disease. Normally, AIRE drives low-level expression of huge numbers of peripheral tissue-specific antigens (TSAgs) in medullary thymic epithelial cells (mTECs), leading to the deletion of TSAg-reactive thymocytes maturing nearby. The very recently discovered neutralizing autoantibodies (autoAbs) against Th17-related cells and cytokines in two autoimmunity-related syndromes associated with AIRE-mutant thymi or AIRE-deficient thymomas help to explain the chronic mucocutaneous candidiasis (CMC) seen in both syndromes. The surprising parallels between these syndromes also demand new hypotheses and research into the consequences of AIRE deficiency and the ensuing autoimmunizing pathways, and suggest more appropriate treatment regimens as discussed in this review.

Digital Repository Infrastructure Vision for European Research (DRIVER)

A study was performed to assess the in vivo relevance of the in vitro antagonism between fluconazole and amphotericin B against Candida albicans. Combinations of fluconazole and amphotericin B were explored for their efficacies against acute (100% mortality in 2 to 5 days) or less acute (100% mortality in 30 days) invasive candidiasis infections in mice with healthy immune systems and immunocompromised mice. Treatment efficacy was assessed by protection from mortality and/or a reduction in th...

Synthetic glycopeptide vaccines combining ?-mannan and peptide epitopes induce protection against candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The first fully synthetic glycopeptide vaccines against a fungal disease have been used to combat disseminated candidiasis in mice. Six T cell peptides found in Candida albicans cell wall proteins were selected by algorithm peptide epitope searches; each was synthesized and conjugated to the fungal cell wall ?-mannan trisaccharide [?-(Man)3] by novel saccharide-peptide linker chemistry to create glycopeptide conjugates. The six proteins were selected because of expression during human candi...

Effects of preinduced Candida-specific systemic cell-mediated immunity on experimental vaginal candidiasis.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

It has been postulated that systemic cell-mediated immunity (CMI) is an important host defense factor against recurrent vaginal infections caused by Candida albicans. Using an estrogen-dependent murine model of vaginal candidiasis, we have previously shown that mice inoculated vaginally with C. albicans acquire a persistent vaginal infection and develop Candida-specific Th1-type systemic CMI. In the present study, experimental vaginitis was monitored in the presence of preinduced systemic Can...

The role of systemic cell-mediated immunity (CMI) as a host defense mechanism in the vagina is poorly understood. Using a murine pseudoestrus model of experimental vaginal candidiasis, we previously found that animals given a vaginal inoculum of viable Candida albicans blastoconidia acquired a persistent vaginal infection and developed Candida-specific delayed-type hypersensitivity (DTH) responses. The present study was designed to characterize the peripheral CMI reactivity generated from the...

Invasive Candidiasis due to Candida Norvegensis in a Liver Transplant Patient: Case Report and Literature Review.  

Science.gov (United States)

Candida norvegensis is an emerging fluconazole-resistant pathogen isolated in most cases from skin and mucous membranes of immunocompromized patients. Documented invasive candidiasis (IC) due to C. norvegensis has been rarely reported, thus the clinical features of patients at risk for this pathogen are poorly defined. We report a liver transplant patient who developed IC due to C. norvegensis and review other cases of C. norvegensis IC published in the literature. PMID:25002960

Molecular Analysis of Fungal Populations in Patients with Oral Candidiasis Using Internal Transcribed Spacer Region  

Science.gov (United States)

Oral candidiasis is closely associated with changes in the oral fungal flora and is caused primarily by Candida albicans. Conventional methods of fungal culture are time-consuming and not always conclusive. However, molecular genetic analysis of internal transcribed spacer (ITS) regions of fungal rRNA is rapid, reproducible and simple to perform. In this study we examined the fungal flora in patients with oral candidiasis and investigated changes in the flora after antifungal treatment using length heterogeneity-polymerization chain reaction (LH-PCR) analysis of ITS regions. Fifty-two patients with pseudomembranous oral candidiasis (POC) and 30 healthy controls were included in the study. Fungal DNA from oral rinse was examined for fungal species diversity by LH-PCR. Fungal populations were quantified by real-time PCR and previously-unidentified signals were confirmed by nucleotide sequencing. Relationships between the oral fungal flora and treatment-resistant factors were also examined. POC patients showed significantly more fungal species and a greater density of fungi than control individuals. Sixteen fungi were newly identified. The fungal populations from both groups were composed predominantly of C. albicans, though the ratio of C. dubliniensis was significantly higher in POC patients than in controls. The diversity and density of fungi were significantly reduced after treatment. Furthermore, fungal diversity and the proportion of C. dubliniensis were positively correlated with treatment duration. These results suggest that C. dubliniensis and high fungal flora diversity might be involved in the pathogenesis of oral candidiasis. We therefore conclude that LH-PCR is a useful technique for diagnosing and assessing the severity of oral candidal infection.

Triple antifungal therapy for severe systemic candidiasis allowed performance of allogeneic stem cell transplantation.  

Science.gov (United States)

Systemic candidiasis is a rare but life threatening complication in immunosuppressed patients undergoing allogeneic SCT. Combination of new antifungal agents may improve outcome in this patient population. Here, triple anti-mycotic therapy is described in an relapsed ALL patient in urgent need of allogeneic bone marrow transplantation. The patient with T-cell acute lymphoblastic leukemia of thymic differentiation achieved remission after treatment according to the German ALL protocol 07/03. Two months after the consolidation therapy relapse occurred requiring high dose chemotherapy with allogeneic stem cell transplantation. One day after start of the conditioning regimen the patient showed skin manifestations typical for septic mycosis and blood cultures became positive for Candida krusei while on fluconazole prophylaxis. Because of the limited sensibility of fluconazole resistant candida species to liposomal amphotericin B and the high mortality rate in patients with systemic candidiasis, voriconazole was added immediately to liposomal amphotericin B. Since fever did not resolve and the conditioning therapy for allogeneic transplantation was not yet completed caspofungin was added. Skin manifestation responded to this triple anti-mycotic combination and peripheral blood stem cells from an unrelated donor were transplanted. With the triple antifungal therapy the patient finally became afebrile, skin manifestations showed complete resolution and blood cultures became negative. Three months after the onset of systemic candidiasis the patient was fully active with no signs of fungal infection and in haematological and molecular remission. Mycotic sepsis at the start of myeloablative conditioning therapy in heavily pretreated acute leukemia patients is usually considered as not allowing successful allogeneic transplantation. Thus this case demonstrates, that allogeneic stem cell transplantation is feasible in patients presenting with systemic candidiasis if combined antifungal therapy with liposomal amphotericin B, caspofungin and voriconazole is given.

[Vaginal candidiasis: etiology and sensitivity profile to antifungal agents in clinical use].  

Science.gov (United States)

Candida vaginitis is one of the most frequent infection of the female genital tract with a high incidence. Approximately 75% of sexually active women suffer at least one episode of Candida vaginitis and 10% of them have recurrent episodes. Pregnancy, diabetes mellitus and antibiotic treatment are the most common predisposing factors, C. albicans is the etiologic agent most frequently found. The widespread reports of fluconazole resistance in Candida species and the selection of non Candida albicans prompted the study of species distribution of vulvovaginal candidiasis and their in vitro susceptibility against current antifungal agents. A total of 314 women with vaginal infection were studied. Yeasts were isolated from 104 patients with vulvovaginal candidiasis. The following species were identified: C. albicans 87.5%, C. glabrata 8.6% and 3.9% included C. krusei, C. famata, C. tropicalis and S. cerevisiae. The minimal inhibitory concentration (MIC) was determined for nystatin, isoconazole, fluconazole and ketoconazole, using a broth microdilution method based on NCCLS procedure. Although most of the isolates were C. albicans, the high percentage of C. glabrata recovered suggests the need to identify the yeasts isolated. Fluconazole resistant C. albicans were isolated in 13.46% of the cases. Thus, further studies are required to correlate the possible role of these strains in recurrent vulvovaginal candidiasis.

Undiagnosed invasive candidiasis: incorporating non-culture diagnostics into rational prophylactic and preemptive antifungal strategies.  

Science.gov (United States)

The insensitivity of blood cultures for diagnosing invasive candidiasis fuels prophylactic and preemptive antifungal treatment. Assays like serum ?-D-glucan or mannan/anti-mannan detection can identify blood culture-negative invasive candidiasis, but their roles in guiding antifungal therapy are undefined. We propose that non-culture tests can be incorporated into rational management strategies, based on clinical setting. As an example, ?-D-glucan sensitivity/specificity for blood culture-negative, deep-seated candidiasis is approximately 60/75%. In intensive care units with 99% and 6/98%, respectively. With pre-test likelihoods of 10 and 33%, positive/negative predictive values are 20/94% and 54/79%, respectively. Based on these data, negative and positive ?-D-glucan results likely will be most useful for discontinuing prophylaxis among low-risk to moderate-risk patients (pre-test likelihoods ?3-10%), and triggering preemptive therapy among moderate-risk to high-risk patients (pre-test likelihoods ?10-25%), respectively. In extremely high-risk patients, universal prophylaxis is likely to be the best strategy. PMID:24850393

Interleukin-17-induced protein lipocalin 2 is dispensable for immunity to oral candidiasis.  

Science.gov (United States)

Oropharyngeal candidiasis (OPC; thrush) is an opportunistic fungal infection caused by the commensal microbe Candida albicans. Immunity to OPC is strongly dependent on CD4+ T cells, particularly those of the Th17 subset. Interleukin-17 (IL-17) deficiency in mice or humans leads to chronic mucocutaneous candidiasis, but the specific downstream mechanisms of IL-17-mediated host defense remain unclear. Lipocalin 2 (Lcn2; 24p3; neutrophil gelatinase-associated lipocalin [NGAL]) is an antimicrobial host defense factor produced in response to inflammatory cytokines, particularly IL-17. Lcn2 plays a key role in preventing iron acquisition by bacteria that use catecholate-type siderophores, and lipocalin 2(-/-) mice are highly susceptible to infection by Escherichia coli and Klebsiella pneumoniae. The role of Lcn2 in mediating immunity to fungi is poorly defined. Accordingly, in this study, we evaluated the role of Lcn2 in immunity to oral infection with C. albicans. Lcn2 is strongly upregulated following oral infection with C. albicans, and its expression is almost entirely abrogated in mice with defective IL-17 signaling (IL-17RA(-/-) or Act1(-/-) mice). However, Lcn2(-/-) mice were completely resistant to OPC, comparably to wild-type (WT) mice. Moreover, Lcn2 deficiency mediated protection from OPC induced by steroid immunosuppression. Therefore, despite its potent regulation during C. albicans infection, Lcn2 is not required for immunity to mucosal candidiasis. PMID:24343647

Full Text Available SciELO Costa Rica | Language: Spanish Abstract in spanish La sobrevida de los pacientes con enfermedades crónicas así como de aquellos expuestos a terapias médicas y quirúrgicas agresivas ha aumentado. entre otras cosas, gracias al empleo de antibiáticos de amplio espectro, al uso de nutrición parenteral, a la aplicación de medicamentos inmunomoduladores, [...] al transpiante de órganos y al desarrollo de las unidades de cuidado intensivo. No obstante, esto ha conllevado a la aparición de complicaciones como son las infecciones por hongos. Dentro de éstas, en los últimos años se ha demostrado que las diversas especies de cándida tienen un papel importante. La candidiasis sistémica puede ser una complicación severa en estos pacientes, con una alta morbimortalidad. En nuestro medio, desconocemos estudios donde se analice esta patología, razón por la cual se llevó a cabo este trabajo. Se estudiaron retrospectivamente los pacientes con candidiasis sistémica diagnosticados en el Hospital San Juan de Dios, hospital nacional de aproximadamente 700 camas, entre los meses de enero de 1996 a diciembre de 1998. Se analizaron 48 episodios de candidiasis sistémica en 47 pacientes. La edad promedio fue de 53 años, 60% fueron hombres. La mortalidad fue de 36%. En 77% de los pacientes se logró identificar alguna patología de base (enfermedad hematooncológica, diabetes mellitus, cirugía abdominal, enfermedad por VIH, quemaduras extensas). Los principales factores de riesgo demostrados fueron el uso previo de antibióticos de amplio espectro (87%), presencia de catéter venoso central (72%), candidiasis en otros sitios (64%), cirugía abdominal previa (25%),empleo de nutrición parenteral (23%) y uso de corticoesteroides (23%). En todos los pacientes se logró identificar al menos un factor de riesgo. Las principales especies de cándida aisladas fueron C albicans (47%), C tropicalis (19%), C parapsilosis (11%), C krusei (4%) y C glabrata (2%). Se analizó la relación entre la especie aislada y los factores de riesgo. Se encontró que C krusei y C parapsílosís se relacionaron con el uso previo de antimicóticos azoles. La mortalidad fue mayor en aquellos pacientes no tratados con antimicóticos. Se discuten estos hallazgos y se correlacionan con lo publicado en la literatura médica, llamándose la atención sobre el aumento en la incidencia de candidiasis sistémicas por candidas no aibicans.

Detection of acute and treated lesions of hepatosplenic candidiasis: comparison of dynamic contrast-enhanced CT and MR imaging.  

Science.gov (United States)

Dynamic contrast-enhanced computed tomography (CT) was compared with 1.5-T magnetic resonance (MR) imaging with FLASH (fast low-angle shot), gadolinium-enhanced FLASH (Gd-FLASH), and T2-weighted fat-suppression (T2FS) sequences in 11 patients with hematologic malignancies, five with biopsy-confirmed hepatosplenic candidiasis treated with antifungal chemotherapy and six with a clinical history suggestive of acute hepatosplenic candidiasis. CT and MR images were separately interpreted in a prospective fashion. MR imaging showed lesions compatible with candidiasis in the liver in six patients, the spleen in five, and the kidneys in one. CT showed candidiasis-compatible lesions in the liver in three patients and the spleen in one; no renal lesions were shown. Differences between acute and treated candidal lesions were observed. Gd-FLASH images showed the most liver lesions (n = 106), followed by FLASH (n = 85), T2FS (n = 20), and CT (n = 18). MR imaging performed better than CT in distinguishing candidal hepatic lesions from recurrent lymphoblastic lymphoma in one patient and from hepatic infarcts in another. The results suggest that MR imaging may be superior to CT in detecting lesions of hepatosplenic candidiasis. PMID:1627870

A randomized phase III prospective trial of bethanechol to prevent mucositis, candidiasis, and taste loss in patients with head and neck cancer undergoing radiotherapy. A secondary analysis  

International Nuclear Information System (INIS)

The aim of this study was to determine the impact of bethanechol administration concomitant to radiotherapy (RT) on oral mucositis, candidiasis and taste loss. We performed a secondary analysis of a previously conducted prospective randomized trial which evaluated the effect of bethanechol on salivary gland dysfunction before, during, and after RT for head and neck cancer (HNC), in comparison to artificial saliva. Mucositis, candidiasis and taste loss were analyzed in 36 patients. Mucositis was scored using the World Health Organization (WHO) method; candidiasis was diagnosed by means of clinical examination, whereas taste loss was assessed by the patients' subjective report of absence of taste. No significant differences were observed between groups in relation to frequency and severity of mucositis or frequency of candidiasis and taste loss. In conclusion, bethanechol does not appear to reduce the incidence of mucositis, candidiasis, and taste loss when administered during RT. (author)

Incidence and anatomic localization of oral candidiasis in patients with AIDS hospitalized in a public hospital in Belo Horizonte, MG, Brazil  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english The objective of this study was to evaluate the incidence, anatomic localization and yeast species isolated from each clinical type of oral candidiasis. The clinical samples were obtained from 67 patients with AIDS with CD4 cell counts below 200 cells/mm³ and hospitalized in a public hospital (Eduar [...] do de Menezes Hospital) in the city of Belo Horizonte, MG, Brazil. Yeasts were isolated using Chromagar® Candida. The results show that 50.7% of these patients had oral candidiasis. The pseudomembranous form was the most frequent clinical manifestation of oral candidiasis, followed by the erythematous and angular cheilite forms. The most common site of these clinical forms of oral candidiasis was the tongue. Candida albicans was the most common yeast species isolated from the lesions. However, other species were also found to be associated with these forms of oral candidiasis.

Treatment of asymptomatic vaginal candidiasis in pregnancy to prevent preterm birth: an open-label pilot randomized controlled trial  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Although the connection between ascending infection and preterm birth is undisputed, research focused on finding effective treatments has been disappointing. However evidence that eradication of Candida in pregnancy may reduce the risk of preterm birth is emerging. We conducted a pilot study to assess the feasibility of conducting a large randomized controlled trial to determine whether treatment of asymptomatic candidiasis in early pregnancy reduces the incidence of preterm birth. Methods We used a prospective, randomized, open-label, blinded-endpoint (PROBE study design. Pregnant women presenting at Candida were randomized to 6-days of clotrimazole vaginal pessaries (100mg or usual care (screening result is not revealed, no treatment. The primary outcomes were the rate of asymptomatic vaginal candidiasis, participation and follow-up. The proposed primary trial outcome of spontaneous preterm birth Results Of 779 women approached, 500 (64% participated in candidiasis screening, and 98 (19.6% had asymptomatic vaginal candidiasis and were randomized to clotrimazole or usual care. Women were not inconvenienced by participation in the study, laboratory testing and medication dispensing were problem-free, and the follow-up rate was 99%. There was a tendency towards a reduction in spontaneous preterm birth among women with asymptomatic candidiasis who were treated with clotrimazole RR = 0.33, 95%CI 0.04-3.03. Conclusions A large, adequately powered, randomized trial of clotrimazole to prevent preterm birth in women with asymptomatic candidiasis is both feasible and warranted.

Role of neutrophils in IL-17-dependent immunity to mucosal candidiasis.  

Science.gov (United States)

Oropharyngeal candidiasis (OPC), caused by the commensal fungus Candida albicans, is an opportunistic infection associated with infancy, AIDS, and IL-17-related primary immunodeficiencies. The Th17-associated cytokines IL-23 and IL-17 are crucial for immunity to OPC, but the mechanisms by which they mediate immunity are poorly defined. IL-17RA-deficient humans and mice are strongly susceptible to OPC, with reduced levels of CXC chemokines and concomitantly impaired neutrophil recruitment to the oral mucosa. Paradoxically, humans with isolated neutropenia are typically not susceptible to candidiasis. To determine whether immunity to OPC is mediated via neutrophil recruitment, mice lacking CXCR2 were subjected to OPC and were found to be highly susceptible, although there was no dissemination of fungi to peripheral organs. To assess whether the entire neutrophil response is IL-17 dependent, IL-17RA(-/-) and IL-23(-/-) mice were administered neutrophil-depleting Abs and subjected to OPC. These mice displayed increased oral fungal burdens compared with IL-17RA(-/-) or IL-23(-/-) mice alone, indicating that additional IL-17-independent signals contribute to the neutrophil response. WT mice treated with anti-Gr-1 Abs exhibited a robust infiltrate of CD11b(+)Ly-6G(low)F4/80(-) cells to the oral mucosa but were nonetheless highly susceptible to OPC, indicating that this monocytic influx is insufficient for host defense. Surprisingly, Ly-6G Ab treatment did not induce the same strong susceptibility to OPC in WT mice. Thus, CXCR2(+) and Gr-1(+) neutrophils play a vital role in host defense against OPC. Moreover, defects in the IL-23/17 axis cause a potent but incomplete deficiency in the neutrophil response to oral candidiasis. PMID:24442441

Hepatosplenic candidiasis in the era of new antifungal drugs: a study in Paris 2000-2007.  

Science.gov (United States)

We report a retrospective study of 24 patients with haematological malignancy and hepatosplenic candidiasis. Clinical and biological features were similar to previous reports. No patient previously received antifungal prophylaxis. Liver or spleen histological examination revealed yeasts in 6/24 patients (25%) on direct examination but all cultures were negative. After a median duration of 7 months, antifungal treatment was discontinued in 58% of the patients with no relapse. Eleven (46%) patients died during follow up. After multivariate analysis, independent factors associated with death were the duration of neutropenia (p 0.022) and relapsing haematological malignancy (p 0.015). PMID:22458883

A comparative clinical evaluation of econazole nitrate, miconazole, and nystatin in the treatment of vaginal candidiasis.  

Science.gov (United States)

A controlled triple open clinical study on three vaginal tablets--Econazole nitrate, Miconazole and Nystatin, was carried out. Seventy-five patients, aged between 18 and 45 years, presenting with mycologically proven cases of vaginal candidiasis, met certain set criteria and were admitted into the study. Twenty-five patients were randomly assigned to each of the three treatment groups. Results of the study showed that at the 4th week after treatment, Econazole was comparable in antifungal action to Miconazole (x2 = 0.2128; p > 0.05) but significantly more antifungal than Nystatin (x2 = 8.8540; P 0.05).

Ketoconazole hepatotoxicity in a patient treated for environmental illness and systemic candidiasis  

Energy Technology Data Exchange (ETDEWEB)

Environmental illness, a hypothesized disease caused by exposure to substances such as combustion products, pesticides, food additives, and Candida albicans, is discussed. The case of a patient with environmental illness and systemic candidiasis for six weeks with ketoconazole, liver enzyme concentrations increased. One month after discontinuation of ketoconazole, the liver enzyme concentrations decreased; however, over the next five months, liver enzymes and bilirubin increased. The patient developed encephalopathy and eventually was transferred to a medical center for possible liver transplant. A review of the literature pertaining to ketoconazole hepatotoxicity is also presented.16 references.

Mouse strain-dependent differences in estrogen sensitivity during vaginal candidiasis.  

Science.gov (United States)

The animal models available for studying the immune response to genital tract infection require induction of a pseudo estrous state, usually achieved by administration of 17-?-estradiol. In our experimental model of vaginal candidiasis, under pseudo estrus, different strains of mice were used. We observed major differences in the clearance of Candida albicans infection among the different strains, ascribable to differing susceptibility to estradiol treatment. In the early phase of infection CD1, BALB/c, C57BL/6 albino and C57BL/6 mice were colonized to similar levels, while in the late phase of infection, BALB/c mice, which are considered genetically resistant to C. albicans infection, exhibited greater susceptibility to vaginal candidiasis than CD1 and C57BL/6 albino strains of mice. This was because estradiol induced "per se" enlarged and fluid-filled uteri, more pronounced in infected mice and consistently more evident in BALB/c and C57BL/6 mice than in CD1 mice. Unlike CD1, BALB/c and C57BL/6 mice showed a heavy fungal colonization of the uterus, even though C57BL/6 mice apparently cleared C. albicans from the vagina. The presence of C. albicans in the vagina and uterus was accompanied by a heavy bacterial load. Collectively these observations prompted us to carry out a careful analysis of estradiol effects in a mouse model of vaginal infection. PMID:23054331

Evaluation of Syngonanthus nitens (Bong.) Ruhl. extract as antifungal and in treatment of vulvovaginal candidiasis.  

Science.gov (United States)

The purpose of this study was to evaluate the in vitro anticandidal activity of a methanolic extract of Syngonanthus nitens scapes against different Candida species and clinical isolates from patients with vulvovaginal candidiasis (VVC), and its effect in vivo in the treatment of vaginal infection. Chemical characterization of the extract was performed by HPLC-UV analyses and showed the presence of flavones derivatives. The extract was effective against several Candida strains from our collection and species recovered from VVC patients, and was able to inhibit the yeast-hyphal transition. No cytotoxic activity against human female reproductive tract epithelial cells and no hemolytic activity against human red blood cells were observed. In the in vivo model of VVC, we evaluated the efficacy of the intravaginal treatment with a cream containing the extract at doses of 0.5, 1.0 and 2.0%. The treatment eradicated the vaginal fungal burden in infected rats after 8 days of treatment. S. nitens extract could be considered as an effective and non-toxic natural antifungal agent in the treatment of vulvovaginal candidiasis. PMID:23758104

Systemic candidiasis in farm-reared red-legged partridges (Alectoris rufa caused by Leucosporidium spp  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background This report describes the results of radiological, histological and molecular examination of three farm-reared red-legged partridges (Alectoris rufa affected by candidiasis. Case presentation Three juvenile farm-reared red-legged partridges in a batch of 100 of the same species were sent for clinical and pathological investigations. The owner referred of a sudden isolation of the sick animals, with apathy, diarrhea, ruffled plumage and respiratory rattles. Post mortem total body lateral projection radiograph showed an increased perihilar interstitial pattern and air bronchogram signs due to lung edema. At necropsy, carcasses showed cachexia; the pericloacal region was soiled by diarrheic fecal material. From the mouth to the intestine, a mucous yellowish fluid was present on a slightly reddish mucosa. Histopathology showed slight edema and congestion with different free fungal elements, referable to blastospores, hyphae and pseudohyphae. Biomolecular exam identified the most similar sequences as belonging to Leucosporidium scottii. Conclusion To our knowledge, this case report describes for the first time this fungal species as a causative agent of candidiasis in birds.

Diagnostic laparoscopy in patients with acute leukemia and suspected hepatic candidiasis.  

Science.gov (United States)

To assess the value of laparoscopy in the diagnosis of suspected hepatosplenic candidiasis in patients with acute leukemia, a retrospective analysis of 28 laparoscopies was conducted. In all but two cases, imaging of the liver showed focal lesions before laparoscopy. Diagnosis of hepatic candidiasis was established significantly more often when the biopsy was targeted at white nodules (in 12 of 22 laparoscopies) than when targeted randomly or at scars (0 of 6 laparoscopies) (p = 0.017, chi-square test). Yeast was detected more often if the laparoscopy was performed during the three-week period after recovery from neutropenia (in 8 of 12 laparoscopies) than when performed later (in 4 of 16 laparoscopies) (p = 0.028, chi-square test). In addition to the 12 laparoscopically diagnosed patients, eight (29%) patients were diagnosed with disseminated Candida infection by other methods. In another eight (29%) patients the causative agent was not identified. No bleeding or other problems occurred after the laparoscopy. Laparoscopy-guided liver biopsy is most useful if biopsies are targeted to macroscopic lesions and if laparoscopy is performed soon after recovery from neutropenia. PMID:9352255

Successful treatment of hepatosplenic candidiasis with a liposomal amphotericin B preparation.  

Science.gov (United States)

The case of a granulocytopenic patient with acute undifferentiated leukaemia and hepatosplenic candidiasis who was refractory to conventional deoxycholate amphotericin B (AmpB) and 5-flucytosine therapy is reported. He experienced severe AmpB-related side-effects, and was subsequently successfully treated with a pharmaceutical preparation of AmpB (5.7 g) entrapped in sonicated liposomes, composed of lecithin, cholesterol and stearylamine in a molar ratio of 4:3:1. Three months later, during maintenance chemotherapy, liposomal AmpB (5.1 g) was reinstituted due to the finding of biopsies positive for Candida albicans at bronchoscopy. After healing of the patient's fungal infection a left upper lobe resection was performed, which showed advanced fibrosis with signs of inflammation, but no evidence of fungal disease. Since no acute side-effects and only moderate hypokalaemia were observed, it appears that liposomal AmpB is superior to conventional AmpB treatment in granulocytopenic patients with hepatosplenic candidiasis and unbearable therapy-related side-effects.

Long Term Vaginal Azoles Versus Prophylactic Oral Fluconazole in Treatment of Recurrent Vulvovaginal Candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Recurrent Vulvovaginal Candidiasis (RVVC is a fungal infection of the vagina and vulva that occur usually = 4 episodes in a year. Our object was to compare the efficacy and safety of a single oral dose of fluconazole (150 mg weekly with clotrimazole vaginal cream 150 mg twice weekly for 6 months as treatment of recurrent VVC. We conducted a clinical trial study among 124 women with Recurrent Vulvovaginal Candidiasis (RVVC among patients presenting to the Obstetrics and Gynecology Clinics of Tabriz University of Medical Sciences from 2002-2004. There was no significant difference in the therapeutic response as the recurrence rate during 12 months between the two groups. The drug side effects in the fluconazole group were significantly more than clotrimazole group. The satisfactory from the drug in the fluconazole group was significantly less than clotrimazole group. Due to the fewer side effects and more satisfactory of local treatment, we recommend profilactic use of Azole vaginal creams for treatment of RVVC especially in women who are pregnant or have systemic problems.

Directory of Open Access Journals (Sweden)

Full Text Available Disturbance on the immune system and deficiency of Zn is two factors which often trigger vaginal candidiasis patient. The aim of the research was to study the effect of virgin coconut oil (VCO enriched with Zn to the amount of neutrophil and lymphocyte subset cells, and the level of IL-2 and IgG in vaginal candidiasis patient. Thirty women were grouped into three (ten women in each group: A, B and C, and intervened for two months. Women in A group were intervened with two tablespoon/day; those in B group were intervened with one tablespoon/day; while those in C group served as control (placebo. Blood was sampled at baseline time, one and two months after intervention. Hematological test by Micros-OT was done on a part of blood, and the plasma was used for IL-2 and IgG level tests using ELISA. The virgin coconut oil enriched with Zn maintained the number of neutrophil and NK cells, but increased Tc cells from 521 to 649 cells/mm3, increased Th cells from 1.090 to 1.380 cells/mm3. The enriched VCO also increase level of IL-2 from 0.25313 to 0.27337 pg/ml, while the IgG level changed from equivocal to negative. The recommended dosage was one tablespoon each day.

Echinocandins in the treatment of candidaemia and invasive candidiasis: clinical and economic perspectives.  

Science.gov (United States)

Candidaemia and invasive candidiasis (IC) complicate modern medical therapy, contributing to high morbidity and mortality. Managing candidiasis is costly, with an additional healthcare expenditure of nearly US$300 million annually. Recent consensus guidelines have suggested the use of newer antifungal agents, such as echinocandins, for the treatment of candidaemia and IC owing to promising clinical outcomes compared with older-generation antifungal agents, but at higher drug acquisition and administration costs. Comprehensive cost-effectiveness data for echinocandins in treating candidaemia and IC remain relatively scant, underlining the need for more studies to incorporate robust economic analyses into clinical decisions. Assessment of the cost efficiencies of these expensive antifungal agents is essential for maximising health outcomes within the constraints of healthcare resources. This review will explore the epidemiology of candidaemia and IC in the context of clinical and economic aspects of the antifungal agents used to treat IC, especially the echinocandins. Standardising the outcome measure, methodology and reporting of results used in economic studies is central to ensure validity and comparability of the findings. Future studies comparing the economic advantages of all available antifungal treatment options and in the context of new diagnostic tools for fungal infections are anticipated. PMID:24670423

Antifungal treatment with carvacrol and eugenol of oral candidiasis in immunosuppressed rats  

Directory of Open Access Journals (Sweden)

Full Text Available Carvacrol and eugenol, the main (phenolic components of essential oils of some aromatic plants, were evaluated for their therapeutic efficacy in the treatment of experimental oral candidiasis induced by Candida albicans in immunosuppressed rats. This anticandidal activity was analyzed by microbiological and histopathological techniques, and it was compared with that of nystatin, which was used as a positive control. Microbiologically, carvacrol and eugenol significantly (p<0.05 reduced the number of colony forming units (CFU sampled from the oral cavity of rats treated for eight consecutive days, compared to untreated control rats. Treatment with nystatin gave similar results. Histologically, the untreated control animals showed numerous hyphae on the epithelium of the dorsal surface of the tongue. In contrast no hyphal colonization of the epithelium was seen in carvacrol-treated animals, while in rats treated with eugenol, only a few focalized zones of the dorsal surface of the tongue were occupied by hyphae. In the nystatin treated group, hyphae were found in the folds of the tongue mucosa. Thus, the histological data were confirmed by the microbiological tests for carvacrol and eugenol, but not for the nystatin-treated group. Therefore, carvacrol and eugenol could be considered as strong antifungal agents and could be proposed as therapeutic agents for oral candidiasis.

Patterns of Expression of Vaginal T-Cell Activation Markers during Estrogen-Maintained Vaginal Candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available The immunosuppressive activity of estrogen was further investigated by assessing the pattern of expression of CD25, CD28, CD69, and CD152 on vaginal T cells during estrogen-maintained vaginal candidiasis. A precipitous and significant decrease in vaginal fungal burden toward the end of week 3 postinfection was concurrent with a significant increase in vaginal lymphocyte numbers. During this period, the percentage of CD3+, CD3+CD4+, CD152+, and CD28+ vaginal T cells gradually and significantly increased. The percentage of CD3+ and CD3+CD4+ cells increased from 43% and 15% at day 0 to 77% and 40% at day 28 postinfection. Compared with 29% CD152+ vaginal T cells in naive mice, > 70% of vaginal T cells were CD152+ at day 28 postinfection. In conclusion, estrogen-maintained vaginal candidiasis results in postinfection time-dependent changes in the pattern of expression of CD152, CD28, and other T-cell markers, suggesting that T cells are subject to mixed suppression and activation signals.

Acute Neutropenia Decreases Inflammation Associated with Murine Vaginal Candidiasis but Has No Effect on the Course of Infection  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We have used a mouse model of vaginal candidiasis to determine the effect of neutrophil depletion on (a) the clearance of Candida albicans and (b) the degree of inflammation associated with infection. No differences in recoverable yeast number or rate of clearance were observed between normal and neutrophil-depleted mice; however, vaginal inflammation was significantly decreased in neutrophil-depleted animals.

Evaluation of single-drug and combination antifungal therapy in an experimental model of candidiasis in rabbits with prolonged neutropenia.  

Science.gov (United States)

We developed an experimental model of candidiasis in rabbits with prolonged neutropenia. Rabbits were made neutropenic with cytosine arabinoside (Ara-C) administered through an indwelling silastic catheter that had been surgically implanted in the external jugular vein. Neutropenia was sustained with intravenous Ara-C, and bacterial complications were prevented with parenteral ceftazidime plus ampicillin. Candidiasis was established by intravenously administering Candida albicans or Candida tropicalis (1-2 x 10(5) colony-forming units) and resulted in hepatic and splenic lesions that mimicked those associated with hepatosplenic candidiasis in humans. The kidney proved to be the site most refractory to eradication of Candida spp. and offered a target organ for assessing antifungal therapy. We evaluated amphotericin B, 5-flucytosine, ketoconazole, and rifampin, alone and in combination. Although each agent reduced the colony counts of Candida in the liver, spleen, and lung, the combination of amphotericin B and 5-flucytosine was the only regimen effective in eradicating renal candidiasis.

Methods: Observational prospective study conducted from October 2001 to Augu [...] st 2003 in critically ill adults with suspected or confirmed IC. Results: 53 patients met criteria for IC, finding 18 (33.9%) candidemias, 22 (41.5%) disseminated IC, and 13 (24.5%) local IC. We identified 8 (44.4%) C. albicans and 10 (55.6%) non-albicans Candida in candidemias. C. tropicalis was the predominant non-albicans species (27.7%). An 88.8 % of Candidas sp recovered in candidemias were fluconazole susceptible. Overall hospital mortality was 24.5%. Mortality in candidemia was significantly lower than in disseminated IC (16.6 vs 31.8%, p = 0.02). Conclusions: A higher proportion of non-albicans Candida was observed in candidemias from critically ill patients. However, most of these strains were fluconazole susceptible. A lower overall mortality was observed in candidemias.

Sexually transmitted infections, bacterial vaginosis, and candidiasis in women of reproductive age in rural Northeast Brazil: a population-based study  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Population-based data on sexually transmitted infections (STI), bacterial vaginosis (BV), and candidiasis reflect the epidemiological situation more accurately than studies performed in specific populations, but such data are scarce. To determine the prevalence of STI, BV, and candidiasis among women of reproductive age from a resource-poor community in Northeast Brazil, a population-based cross sectional study was undertaken. All women from seven hamlets and the centre of Pacoti municipality...

Amphotericin B lipid complex for the treatment of patients with acute leukemia and hepatosplenic candidiasis.  

Science.gov (United States)

Hepatosplenic candidiasis (HSC) is an emerging complication of the treatment of patients with acute leukemia. Treatment of this infection can be very difficult and data on the duration of antifungal therapy are not available. We evaluated the efficacy of amphotericin B lipid complex (ABLC) for the treatment of five patients with acute leukemia and HSC. The dose of the administered ABLC ranged between 5 and 11 mg/kg per day and the median duration of therapy was 4.3 months. Four patients had complete response to the above treatment with resolution of fever and improvement in the radiologic findings. One patient refused to continue treatment and subsequently died with relapsed leukemia and disseminated Candida infection. Preliminary data suggest that ABLC is a well-tolerated and effective treatment for HSC and should be considered for phase II trials as front line treatment for this type of deep seated fungal infections.

Increased serum concentrations of interleukin-10 in patients with hepatosplenic candidiasis.  

Science.gov (United States)

Hepatosplenic candidiasis (HSC) becomes clinically overt in cancer patients upon recovery from neutropenia. HSC may be a consequence of a Th1-Th2 imbalance, characterized by increased serum levels of one or more cytokines. Serum levels of two immunosuppressive cytokines, markers of the Th2 pathway, interleukin (IL)-4 and IL-10 were measured by ELISA in 10 patients with HSC (22 samples) and compared with 19 healthy blood donors, 13 patients with cancer but no infection (23 samples), and 11 patients with cancer and various bacterial infections (17 samples). IL-4 was undetectable in all controls and patients. By contrast, levels of IL-10 were increased in HSC patients compared with levels in healthy donors and cancer patients without infection (P < .001) or with bacterial infections (P < .01). These findings indicate that IL-10 but not IL-4 is increased in patients with HSC and suggest that IL-10 plays a role in the pathogenesis of this infection. PMID:9697751

Hepatosplenic candidiasis, a late manifestation of Candida septicaemia in neutropenic patients with haematologic malignancies.  

Science.gov (United States)

Systemic candidiasis with Candida-induced abscesses, predominantly in the liver and the spleen, was diagnosed in 27 patients with haematologic malignancies after intensive cytostatic therapy. Specific features included septic fever unresponsive to antimicrobial therapy, hepatosplenomegaly with multiple lesions in the liver and spleen (diameter up to 2 cm) as detected by computed tomography (CT) or ultrasound, and an elevation in liver enzymes. During treatment, induced neutropenia, hepatic and splenic foci were poorly defined histologically and were not identified by imaging procedures. After granulocyte recovery these foci showed characteristic histological patterns. Ultrasound and/or CT investigations of the abdomen now revealed characteristic lesions in the liver and the spleen. Gamma-GT and alkaline phosphatase were early indicators of hepatic involvement in Candida septicaemia and were often already elevated in aplasia. PMID:2337685

Candida albicans double-stranded DNA can participate in the host defense against disseminated candidiasis.  

Science.gov (United States)

In the present work, we studied the in vitro immunomodulatory properties of double-stranded Candida albicans DNA and its protective effect in murine disseminated candidiasis. DNA induced the production of TNF-alpha by peritoneal macrophages and splenocytes in vitro through a chloroquine-dependent mechanism. Yeast DNA acted synergistically with IFN-gamma in triggering the secretion of nitric oxide by macrophages and enabled them to stimulate the proliferation of T cells in response to soluble anti-CD3. The effect of DNA on splenocytes is associated with an enhanced synthesis of IFN-gamma, IL-2 and IL-10. In vivo, DNA decreased the mortality and lowered the kidney contamination in mice intraperitoneally inoculated with C. albicans simultaneously with an increase in the specific proliferative response and cytokine production. The present results indicate that C. albicans DNA can provide protection against disseminated infection. PMID:15715977

CANDIDÍASE CUTÂNEA EM CEBUS APELLA (MACACO PREGO CUTANEOUS CANDIDIASIS IN A CEBUS APELLA (CAPUCHINS MONKEYS  

Directory of Open Access Journals (Sweden)

Full Text Available

Leveduras do gênero Candida têm sido freqüentemente isoladas de animais domésticos e silvestres, entretanto, candidíase não tem sido reportada em primatas. Encaminhou-se à Faculdade de Veterinária, Departamento de Patologia Animal, um macaco-prego (Cebus apella para necropsia, que vinha apresentando emagrecimento profundo e lesões ulcerativas de pele e mucosas. Fragmentos de pele e órgãos foram processados para histologia e corados com H.E. e Groccot. Para micologia, coletaram-se fragmentos de órgãos, exsudato e crostas da pele, sendo realizado exame direto e cultivo a 37oC. Macroscopicamente, o animal apresentava alopecia, caquexia e ulcerações cutâneas de 1-4 cm. Histologicamente, nas ulcerações, a derme continha infiltrado de mononucleares e proliferação fibroblástica. Mediante utilização de Groccot, encontraram-se hifas e/ou pseudo-hifas e blastoconídeos intralesionais. Em cultivos de crostas e exsudato, observaram-se colônias brilhantes, com superfície lisa e coloração branca a creme. A microscopia das colônias revelou células leveduriformes ovaladas ou alongadas, com brotamento unipolar, gram-positivas. No microcultivo em fubá, observaram-se blastoconídeos globosos terminais, com parede espessa e pseudomicélio abundante e ramificado, com formação de tubo germinativo em albumina de ovo, sendo a levedura classificada como Candida albicans. O estudo aborda o risco da infecção por micoses oportunistas como a candidíase em animais silvestres em cativeiro.

 

PALAVRAS-CHAVES: Candidiasis, Candida albicans, pele, Cebus apella.

Candida spp has been frequently isolated from domestic and sylvan animals, however, Candidiasis has not been reported in primates. One Cebus apella, with progressive thinning and ulcerative skin lesions and mucous, was necropsied. Fragments of tissue were collected and processed for histology. Coloration of H.E. and Groccot was made. For mycology was collected tissue, exsudate, and skin crusts. Direct exam was made, and samples cultivated at 37oC in agar Sabouraud with cloranfenicol and agar corn. Macroscopically the animal presented; itself extremely thin with ulcerative lesions on the skin, ranging from 1 to 4 cm. Histologically, on dermis ulcerations, there was mononuclear infiltrate and fibroblastic proliferation. With Groccot, it was observed intralesionally hyphae and blastoconidia. The direct exam showed round and/or ovalate gram positive cells, compatible with yeast. The cultives showed shining colonies with a smooth surface, some of them with edges fringed and white-yellowish coloration. The colonies showed yeast cells with ovalate or alongate forms and sprouting unipolar on microscopy. With microcultive, it was found globosous blastoconidia, with wall thick and pseudohyfaes abundant and ramified. There was the formation of a germinative tube, confirming the C. albicans species. This study shows the risk of candidiasis in wildlife primates living on captivity.

Cell adhesion molecule and lymphocyte activation marker expression during experimental vaginal candidiasis.  

Science.gov (United States)

Cell-mediated immunity by Th1-type CD4(+) T cells is the predominant host defense mechanism against mucosal candidiasis. However, studies using an estrogen-dependent murine model of vaginal candidiasis have demonstrated little to no change in resident vaginal T cells during infection and no systemic T-cell infiltration despite the presence of Candida-specific systemic Th1-type responses in infected mice. The present study was designed to further investigate these observations by characterizing T-cell activation and cell adhesion molecule expression during primary and secondary C. albicans vaginal infections. While flow cytometry analysis of activation markers showed some evidence for activation of CD3(+) draining lymph node and/or vaginal lymphocytes during both primary and secondary vaginal Candida infection, CD3(+) cells expressing the homing receptors and integrins alpha(4)beta(7), alpha(M290)beta(7), and alpha(4)beta(1) in draining lymph nodes of mice with primary and secondary infections were reduced compared to results for uninfected mice. At the local level, few vaginal lymphocytes expressed integrins, with only minor changes observed during both primary and secondary infections. On the other hand, immunohistochemical analysis of vaginal cell adhesion molecule expression showed increases in mucosal addressin cell adhesion molecule 1 and vascular cell adhesion molecule 1 expression during both primary and secondary infections. Altogether, these data suggest that although the vaginal tissue is permissive to cellular infiltration during a vaginal Candida infection, the reduced numbers of systemic cells expressing the reciprocal cellular adhesion molecules may preempt cellular infiltration, thereby limiting Candida-specific T-cell responses against infection.

Immunological Effects of Honey Bee Venom in Mice with Intracerebral Candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Bee Venom (BV is a natural substance, reported to booster the immune system. This study aimed at evaluating the effects of bee venom in stimulation of the immune system in mice infected with intracerebral Candidiasis probing for its possible use in treatment of this ailment. In vivo study included three groups of mice; bee venom-treated Candida infected group, untreated Candida-infected group and control group. Mice in the first two groups received intracerebral (i.c. inoculation of C. albicans, while the control mice were inoculated i.c. with sterile saline. Mice of first group, the BV-treated group; received thereafter SC injection of BV for 4 days. On 5th day, mice of all groups were sacrificed and Candida infection was evaluated by culture of homogenized brain tissue on Sabouraud dextrose agar. Stimulation of the immune system was assessed by determining TNF-? and IFN-? mRNA expression in splenocytes by real-time PCR (RT-PCR. In the in vitro study, direct effect of BV as antifungal agent and its effect on phagocytic function of neutrophils were evaluated. The results revealed that BV-treated mice had significantly low fungal load in the brain, with significantly high TNF-? but insignificantly high IFN-? mRNA expression in splenocytes. BV had no direct antifungal effect, but it enhanced phagocytic activity of neutrophils. It was concluded that treatment with BV could result in significant therapeutic effect in intracerebral Candidiasis and thereby could be effective in resistant life-threatening infections.

Oropharyngeal candidiasis and resistance to antifungal drugs in patients receiving radiation for head and neck cancer  

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND: Oropharyngeal candidiasis is a common infection in patient receiving radiotherapy for head and neckcancer. Accurate and rapid identification of candida species is very important in clinical laboratory, because theincidence of candidiasis continues to rise after radiotherapy. The genus Candida has about 154 species that showdifferent level of resistance to antifungal drugs and have high degree of phenotypic similarity. The aim of this study wasto investigate oral yeast colonization and infection and resistance to antifungal drugs in these patients.METHODS: Thirty patients receiving a 6-week course of radiation therapy for treatment of head and neck cancer at theOncology Unit in Shafa Hospital, in 2008, were enrolled in the study. Specimens from patients were cultured weeklyfor Candida. All isolates were plated on CHROM agar and RPMI-based medium. They were subcultured and submittedfor antifungal susceptibility testing (nystatin, fluconazole, clotrimazole and ketoconazole and molecular typing.RESULTS: Infection (clinical and microbiological evidence occurred in 50% of the patients and Candida colonization(only microbiological evidence occurred in 70% of subjects in the first week. Candida albicans alone was isolated in94.9% of patient visits with positive cultures. Candida tropicalis was isolated from 5.1% of patient visits with positivecultures. All isolates were susceptible to nystatin, but did not respond to the other antifungal drugsCONCLUSIONS: The irradiation-induced changes of the intraoral environment such as xerostomia lead to increasedintraoral colonization by Candida species. All yeast isolates were susceptible to nystatin. Thus prophylactic therapywith nystatin should be considered for these patients.

Avaliação da resposta imune celular em pacientes com candidíase recorrente Evaluation of cellular immune response in patients with recurrent candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available A candidíase recorrente cutânea ou mucosa é caracterizada pela ocorrência de, no mínimo, 4 episódios de candidíase no período de um ano. Não são conhecidos os fatores que levam à recorrência desta infecção. O presente estudo avaliou a resposta linfoproliferativa e a produção de IFN-g de pacientes com candidíase recorrente. Os índices de estimulação da resposta linfoproliferativa em culturas de células de pacientes com candidíase recorrente estimuladas com antígeno de Candida albicans, PPD e TT foram respectivamente de 6±8, 17±20 e 65±30. A adição de anticorpo monoclonal anti-IL-10 às culturas de células de 6 pacientes aumentou a resposta linfoproliferativa de 735±415 para 4143±1746 cpm. A produção de IFN-g em culturas de células estimuladas com antígeno de Candida, foi 162±345pg/ml. Pacientes com candidíase recorrente apresentam uma deficiência na resposta linfoproliferativa e na produção de IFN-g, podendo a resposta imune celular ao antígeno de Candida ser restaurada parcialmente através da neutralização da IL-10 in vitro.Recurrent cutaneous or mucosal candidiasis is characterized by the occurrence of at least four candidiasis episodes within a one-year period. The factors involved in recurrence of infection are still unknown. In the present study the lymphoproliferative response and the IFN-g production by candidiasis patients were evaluated. The stimulation index of mononuclear cell cultures of candidiasis patients stimulated with Candida albicans antigen, PPD and TT were 6±8, 17±20 and 65±30, respectively. The addition of monoclonal antibody anti-IL-10 to Candida albicans antigen stimulated cultures raised the lymphoproliferative response from 735±415 to 4143±1746 cpm. The IFN-g production by cells of candidiasis patients stimulated with Candida albicans antigen was 162±345pg/ml. Candidiasis patients have an impairment in the lymphoproliferative response specific to C. albicans antigen and on IFN-g production and the lymphoproliferative response can be partially restored, in vitro, by IL-10 neutralization.

Microbiological screening of Irish patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy reveals persistence of Candida albicans strains, gradual reduction in susceptibility to azoles, and incidences of clinical signs of oral candidiasis without culture evidence.  

LENUS (Irish Health Repository)

Patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) are prone to chronic mucocutaneous candidiasis, which is often treated with azoles. The purpose of this study was to characterize the oral Candida populations from 16 Irish APECED patients, who comprise approximately half the total number identified in Ireland, and to examine the effect of intermittent antifungal therapy on the azole susceptibility patterns of Candida isolates. Patients attended between one and four clinical evaluations over a 5-year period, providing oral rinses and\\/or oral swab samples each time. Candida was recovered from 14\\/16 patients, and Candida albicans was the only Candida species identified. Interestingly, clinical diagnosis of candidiasis did not correlate with microbiological evidence of Candida infection at 7\\/22 (32%) clinical assessments. Multilocus sequence typing analysis of C. albicans isolates recovered from the same patients on separate occasions identified the same sequence type each time. Fluconazole resistance was detected in isolates from one patient, and isolates exhibiting a progressive reduction in itraconazole and\\/or fluconazole susceptibility were identified in a further 3\\/16 patients, in each case correlating with the upregulation of CDR- and MDR-encoded efflux pumps. Mutations were also identified in the ERG11 and the TAC1 genes of isolates from these four patients; some of these mutations have previously been associated with azole resistance. The findings suggest that alternative Candida treatment options, other than azoles such as chlorhexidine, should be considered in APECED patients and that clinical diagnosis of oral candidiasis should be confirmed by culture prior to the commencement of anti-Candida therapy.

Response to fluconazole by 23 patients with human immunodeficiency virus infection and oral candidiasis: pharmacological and mycological factors.  

Science.gov (United States)

The MICs of fluconazole for strains of Candida species and the levels of fluconazole in serum were determined at day 0 and day 14 for 23 human immunodeficiency virus-infected patients with oral candidiasis who were treated orally with 100 mg of fluconazole per day for 14 days. Among the 23 patients, 11 (48%) were not clinically cured and had persistent isolation of Candidiasis albicans (n = 10) and/or presence of non-C. albicans (n = 6). Clinical response could be predicted by the susceptibility of the strain to fluconazole determined at day 0. All 12 patients who were cured were infected with a strain for which the MIC was 3.12 mg/liter experienced clinical failure. These data suggest that a C. albicans strain could be defined as being susceptible when the MIC of fluconazole is 3.12 mg/liter.

Different tumor necrosis factor ? antagonists have different effects on host susceptibility to disseminated and oropharyngeal candidiasis in mice.  

Science.gov (United States)

Tumor necrosis factor ? is important for the host defense against intracellular pathogens. We tested the effect of mouse analogs of human TNF-? antagonists, the rat anti-mouse TNF-? monoclonal antibody (XT22) and the soluble mouse 75 kDa TNF-? receptor fused to the Fc portion of mouse IgG1 (p75-Fc), on the susceptibility of mice to hematogenously disseminated candidiasis (HDC) and oropharyngeal candidiasis (OPC). Both XT22 and p75-Fc significantly reduced mice survival, increased kidney fungal burden, and reduced leukocyte recruitment during HDC. However, only XT22 significantly increased the oral fungal burden and reduced leukocyte recruitment during OPC. This result suggests that XT22 and p75-Fc affect host susceptibility to different types of Candida albicans infections by different inhibitory mechanisms. PMID:25007095

Many studies to date have convincingly demonstrated a link between filamentation and virulence; however, relatively little is known regarding the role of the filament-to-yeast transition during the pathogenesis of invasive candidiasis. We previously identified the C. albicans pescadillo homolog (PES1) as essential during yeast growth and growth of lateral yeast on hyphae but not during hyphal gro...

Superior efficacy of liposomal amphotericin B with prolonged circulation in blood in the treatment of severe candidiasis in leukopenic mice  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In leukopenic mice with severe systemic candidiasis, single-dose treatment (5 mg of amphotericin B [AMB]/kg of body weight) with long-circulating polyethylene glycol-coated AMB liposomes (PEG-AMB-LIP) resulted in zero mortality and a significant reduction in the number of viable Candida albicans in the kidney, whereas 70% mortality was seen in mice treated with five daily doses of AmBisome (5 mg of AMB/kg . day). When the first ...

Efficacy of micafungin in invasive candidiasis caused by common Candida species with special emphasis on non-albicans Candida species.  

Science.gov (United States)

The incidence of invasive candidiasis caused by non-albicans Candida (NAC) spp. is increasing. The aim of this analysis was to evaluate the efficacy of micafungin, caspofungin and liposomal amphotericin B in patients with invasive candidiasis and candidaemia caused by different Candida spp. This post hoc analysis used data obtained from two randomised phase III trials was conducted to evaluate the efficacy and safety of micafungin vs. caspofungin and micafungin vs. liposomal amphotericin B. Treatment success, clinical response, mycological response and mortality were evaluated in patients infected with C. albicans and NAC spp. Treatment success rates in patients with either C. albicans or NAC infections were similar. Outcomes were similar for micafungin, caspofungin and liposomal amphotericin B. Candida albicans was the most prevalent pathogen recovered (41.0%), followed by C. tropicalis (17.9%), C. parapsilosis (14.4%), C. glabrata (10.4%), multiple Candida spp. (7.3%) and C. krusei (3.2%). Age, primary diagnosis (i.e. candidaemia or invasive candidiasis), previous corticosteroid therapy and Acute Physiology and Chronic Health Evaluation II score were identified as potential predictors of treatment success and mortality. Micafungin, caspofungin and liposomal amphotericin B exhibit favourable treatment response rates that are comparable for patients infected with different Candida spp. PMID:23786573

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) due to AIRET16M mutation in a consanguineous Greek girl.  

Science.gov (United States)

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) or autoimmune polyendocrine syndrome type 1 (APS-1) is a rare autosomal recessive disease caused by mutations of the AutoImmune REgulator (AIRE) gene, an important mediator of tolerance to self-antigens. It is characterized by two out of three major components: chronic mucocutaneous candidiasis, hypoparathyroidism and Addison's disease. We present an 11-year-old girl suffering from recurrent episodes of mucocutaneous candidiasis and onychomycosis from 1 to 6 years of age, and transient alopecia at the age of 4 years. Hypoparathyroidism and dental enamel hypoplasia were diagnosed at 8 years. Autoantibodies to thyroid and adrenal glands were not detected and all other endocrine functions have remained normal. Genetic analysis revealed that the patient was homozygous for the mutation T16M in exon 1 of the AIRE gene (p.T16M, c.47C>T). This is the first APECED case reported for carrying this mutation in homozygous form. Parents were third cousins and heterozygous carriers of this mutation. PMID:21932610

Species distribution and in vitro antifungal susceptibility of oral yeast isolates from Tanzanian HIV-infected patients with primary and recurrent oropharyngeal candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background In Tanzania, little is known on the species distribution and antifungal susceptibility profiles of yeast isolates from HIV-infected patients with primary and recurrent oropharyngeal candidiasis. Methods A total of 296 clinical oral yeasts were isolated from 292 HIV-infected patients with oropharyngeal candidiasis at the Muhimbili National Hospital, Dar es Salaam, Tanzania. Identification of the yeasts was performed using standard phenotypic methods. Antifungal susceptibility to fluconazole, itraconazole, miconazole, clotrimazole, amphotericin B and nystatin was assessed using a broth microdilution format according to the guidelines of the Clinical and Laboratory Standard Institute (CLSI; M27-A2. Results Candida albicans was the most frequently isolated species from 250 (84.5% patients followed by C. glabrata from 20 (6.8% patients, and C. krusei from 10 (3.4% patients. There was no observed significant difference in species distribution between patients with primary and recurrent oropharyngeal candidiasis, but isolates cultured from patients previously treated were significantly less susceptible to the azole compounds compared to those cultured from antifungal naïve patients. Conclusion C. albicans was the most frequently isolated species from patients with oropharyngeal candidiasis. Oral yeast isolates from Tanzania had high level susceptibility to the antifungal agents tested. Recurrent oropharyngeal candidiasis and previous antifungal therapy significantly correlated with reduced susceptibility to azoles antifungal agents.

Valor predictivo de la candidiasis oral como marcador de evolución a SIDA / Predictive value of oral candidiasis as a marker of progression to AIDS  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivo: Determinar la validez de la candidiasis oral (CO) como marcador clínico de evolución en los pacientes infectados por el Virus de la Inmunodeficiencia Humana. Diseño del estudio: En 1992, se efectuó una exploración oral a un colectivo de 200 pacientes infectados por VIH, con una edad media [...] de 36,8±7 años (rango 25-46 años) para establecer el diagnóstico de CO. Se registraron las variables edad, sexo, tiempo de evolución de la enfermedad, conducta de riesgo, número de linfocitos CD4/µL, estadio clínico y tratamiento antirretroviral. De los 200 pacientes del grupo de estudio, 157 no cumplían criterios de SIDA en el momento de la exploración basal y a éstos se les efectuó un seguimiento semestral hasta que cumplieron dichos criterios, concluyendo el estudio al final de 2001. Resultados: De los 157 pacientes seleccionados, 71 (45,2%) no presentaron CO y de éstos el 28,7% evolucionó a SIDA durante el período de seguimiento. De los 86 (54,8%) pacientes con CO, el 48,2% evolucionó a SIDA (RR=2,71). Al trasladar el origen del estudio al año 1997 cuando se inició la administración de la terapia antirretroviral de alta eficacia (TAAE), no se observaron diferencias en el porcentaje de pacientes que evolucionaron a SIDA en relación a la existencia o no de CO en la exploración basal. El análisis multivariante demostró que la asociación de la variable de exposición CO con la evolución a SIDA no alcanzó un valor predictivo. Conclusiones: El valor pronóstico a largo plazo de la CO, no se ha determinado en pacientes que reciben terapia antirretroviral de alta eficacia (TAAE). La recuperación inmunológica y la disminución de enfermedades oportunistas observadas tras la administración de TAAE, hacen que muchos pacientes que alcanzaron la condición de SIDA no cumplan en la actualidad dichos criterios, lo que obliga a renovar la propia definición del síndrome para poder evaluar marcadores de pronóstico. Abstract in english Objective: To determine the validity of oral candidiasis (OC) as a clinical marker of progression in patients with human immunodeficiency virus infection. Study design: In 1992, an oral examination was carried out on a group of 200 HIV-infected patients with a mean age of 36.8 ± 7 years (range 25-46 [...] years) to establish the diagnosis of OC. The following variables were recorded: age, sex, duration of the disease, risk behaviour, CD4 lymphocyte count, clinical stage and antiretroviral treatment. Of the 200 patients in the group evaluated, 157 did not fulfil the criteria for AIDS at the time of the baseline examination; these patients constitute the study group and underwent 6-monthly follow-up until they fulfilled these criteria. The study was concluded at the end of 2001. Results: Of the 157 patients selected, 71 (45.2%) did not present OC and, of these, 28.7% progressed to AIDS during the follow-up period. Of the 86 (54.8%) patients with OC, 48.2% progressed to AIDS (RR= 2.71). If the start date of the study was taken as 1997, when highly active antiretroviral therapy (HAART) was introduced, no differences were found in the percentage of patients who progressed to AIDS with respect to the presence or absence of OC at the baseline examination. Multivariate analysis demonstrated that the association of the presence of OC with progression to AIDS did not reach a predictive value. Conclusions: The long-term prognostic value of OC has not been established in patients receiving highly active antiretroviral therapy (HAART). The immunological recovery and the reduction in the number of opportunistic diseases observed after the administration of HAART means that many patients who developed AIDS do not currently satisfy these criteria, making a review of the definition of the syndrome itself a necessity in order to be able to evaluate prognostic markers.

Inflammatory monocytes mediate early and organ-specific innate defense during systemic candidiasis.  

Science.gov (United States)

Candida albicans is a commensal fungus that can cause systemic disease in patients with breaches in mucosal integrity, indwelling catheters, and defects in phagocyte function. Although circulating human and murine monocytes bind C. albicans and promote inflammation, it remains unclear whether C-C chemokine receptor 2 (CCR2)- and Ly6C-expressing inflammatory monocytes exert a protective or a deleterious function during systemic infection. During murine systemic candidiasis, interruption of CCR2-dependent inflammatory monocyte trafficking into infected kidneys impaired fungal clearance and decreased murine survival. Depletion of CCR2-expressing cells led to uncontrolled fungal growth in the kidneys and brain and demonstrated an essential antifungal role for inflammatory monocytes and their tissue-resident derivatives in the first 48 hours postinfection. Adoptive transfer of purified inflammatory monocytes in depleted hosts reversed the defect in fungal clearance to a substantial extent, indicating a compartmentally and temporally restricted protective function that can be transferred to enhance systemic innate antifungal immunity.

Invasive candidiasis in intensive care unit; consensus statement from an Iranian panel of experts, July 2013  

Science.gov (United States)

Invasive candidiasis (IC) is associated with high mortality in intensive care unit (ICU) patients. Timely diagnosis of this potentially fatal condition remains a challenge; on the other hand, the criteria for initiating empirical antifungal therapy in critically ill patients are not well defined in different patient population and ICU settings. Alongside the international guidelines, reaching regional and local consensus on diagnosis and management of IC in ICU setting is essential. This report summarizes our present status of IC management in ICU, considered by a group of Iranian experts in the fields of intensive care and infectious diseases. A round table of 17 experts was held to review the available data and discuss the optimal treatment strategies for IC in critical care setting. Comparative published data on the management of IC were analytically reviewed and the commonly asked questions about the management of IC in ICU were isolated. These questions were interactively discussed by the panel and audience responses were taken to consolidate point-to-point agreement with the panel arriving at consensus in many instances. The responses indicated that patients’ risk stratification, clinical discretion, fungal diagnostic techniques and the empirical therapy for IC are likely to save more patients. Treatment options were recommended to be based on the disease severity, prior azole exposure, and the presence of suspected azole-resistant Candida species. This report was reviewed, edited and discussed by all participants to include further evidence-based insights. The panel expects such endorsed recommendations to be soon formulated for implementation across the country.

Evaluation of Mucoadhesive Gels with Propolis (EPP-AF) in Preclinical Treatment of Candidiasis Vulvovaginal Infection.  

Science.gov (United States)

Vulvovaginal candidiasis is the second cause of vaginal infection in the USA. Clinical treatment of C. albicans infections is routinely performed with polyenes and azole derivatives. However, these drugs are responsible for undesirable side effects and toxicity. In addition, C. albicans azole and echinocandin resistance has been described. Propolis is a bee product traditionally used due to its antimicrobial, anti-inflammatory, and other properties. Therefore, the present work aimed to evaluate different propolis presentations in order to evaluate their in vitro and in vivo efficacy. The methodologies involved antifungal evaluation, chemical analysis, and the effects of the rheological and mucoadhesive properties of propolis based gels. The obtained results demonstrated the fungicide action of propolis extracts against all three morphotypes (yeast, pseudohyphae, and hyphae) studied. The highest level of fungal cytotoxicity was reached at 6-8 hours of propolis cell incubation. Among the based gel formulations developed, the rheological and mucoadhesive results suggest that propolis based carbopol (CP1%) and chitosan gels were the most pseudoplastic ones. CP1% was the most mucoadhesive preparation, and all of them presented low thixotropy. Results of in vivo efficacy demonstrated that propolis based gels present antifungal action similar to clotrimazole cream, suggesting that future clinical studies should be performed. PMID:23997797

In vivo activity of sertaconazole in experimental candidiasis in the mouse.  

Science.gov (United States)

The antifungal activity of sertaconazole (SZ), 1-(2-[(7-chlorobenzo[b]thien-3-yl)methoxyl]- 2-(2,4-dichlorophenyl)ethyl)-1H-imidazole, has been assessed in vivo in comparison with miconazole (MZ) in a murine vaginal candidiasis model. Mice (eight per group) were maintained in oestrus by subcutaneous injection of oestradiol benzoate (25 mg/kg) 5 days before and 2 days after inoculation intravaginally with 5 x 10(4) blastospores of C. albicans (strain No. 17) in 0.05 ml. Animals were treated with 0.03 ml of the appropriate 2% cream formulation 1 h after infection (single dose regimen) or on days 3, 4 and 5 post-infection (three-dose regimen). The efficacy was measured in each test group by Sabouraud agar plate count of vaginal specimens and expressed as % reduction in the number of yeast cells with regard to the control group (infected and untreated). The two treatments indicated a significant reduction (according to the non-parametric method of Mann-Whitney) (p greater than 0.05) for both SZ (97.9% and 93.6%) and MZ (77.5% and 76.9%) groups. When the values from SZ and MZ were compared, SZ proved more active than MZ in the single dose regimen. PMID:2100249

CD8 T-cells and E-cadherin in host responses against oropharyngeal candidiasis  

Science.gov (United States)

Oropharyngeal candidiasis (OPC) is the most common oral infection in HIV+ persons. Previous studies suggest a role for CD8+ T-cells against OPC when CD4+ T-cells are lost, but enhanced susceptibility to infection occurs when CD8+ T-cell migration is inhibited by reduced tissue E-cadherin. Objective Conduct a longitudinal study of tissue CD8+ T-cells and E-cadherin expression before, during, and after episodes of OPC. Methods Oral fungal burden was monitored and tissue was evaluated for CD8+ T-cells and E-cadherin over a one-year period in HIV+ persons with a history of, or an acute episode of OPC. Results While longitudinal analyses precluded formal interpretations, point prevalence analyses of the dataset revealed that when patients experiencing OPC were successfully treated, tissue E-cadherin expression was similar to patients who had not experienced OPC, and higher numbers of CD8+ T-cells were distributed throughout OPC? tissue under normal expression of E-cadherin. Conclusion These results suggest that 1) reduction in tissue E-cadherin expression in OPC+ patients is not permanent, and 2) high numbers of CD8+ T-cells can be distributed throughout OPC? tissue under normal E-cadherin expression. Together these results extend our previous studies and continue to support a role for CD8+ T-cells in host defense against OPC.

A comparison of butoconazole nitrate cream with econazole nitrate cream for the treatment of vulvovaginal candidiasis.  

Science.gov (United States)

In a randomized, single-blind, parallel study the safety and efficacy of 2% butoconazole nitrate cream used for 3 days were compared with those of 1% econazole nitrate cream used for 7 days at night in patients with vulvovaginal candidiasis. Patients in both treatment groups had positive potassium hydroxide smears and fungal cultures, and were similar in age, disease duration and history, obstetric history and contraceptive use. Of the 75 patients enrolled, 63 with a Candida albicans infection were included in the efficacy analyses. Evaluations were made at the start of the study (visit 1), after 10-23 days (visit 2) and after 24-45 days (visit 3). Both drugs significantly reduced all signs and symptoms, and at visits 2 and 3 the percentages of patients considered microbiologically, clinically and therapeutically cured were consistently higher for butoconazole- than for econazole-treated patients, although differences were not statistically different. Although both drugs were safe and well tolerated, it is concluded that butoconazole because of its much shorter regimen and superior clinical and microbiological performance was the drug of choice.

Efficacy of liposome-intercalated amphotericin B in the treatment of systemic candidiasis in mice.  

Science.gov (United States)

We developed a liposome-intercalated preparation of amphotericin B by using small, unilamellar vesicles 0.06 to 0.1 micron in diameter. In contrast to previously described liposomal preparations of amphotericin B, these vesicles have the advantage that they are small enough to be filter sterilized. We compared the efficacy of liposomal amphotericin B with that of the commercial drug given as an intravenous bolus every other day for 13 days (seven doses) in mice with disseminated candidiasis. Survival rates were similar for the two preparations at each dosage of amphotericin B; however, the highest survival rates occurred at dosages of liposomal amphotericin B which would be lethal to these animals if administered as the commercial drug. Viable colony counts of fungi in various organs, particularly the kidneys, tended to be lower with increasing dosage of the drug. However, some organisms persisted even after 13 days. These studies indicate that liposomal formulations of amphotericin B merit further investigation because of their improved therapeutic margins. PMID:6385839

Prevalence of Candida albicans-closely related yeasts, Candida africana and Candida dubliniensis, in vulvovaginal candidiasis.  

Science.gov (United States)

Isolates of Candida africana and C. dubliniensis were recovered from patients with vulvovaginal candidiasis (VVC). The isolates were initially identified as C. albicans through use of the API Candida System. We retrospectively reexamined 1014 vaginal isolates presumptively determined to be C. albicans at the Department of Obstetrics and Gynecology of Peking University Shenzhen Hospital from 1 January 2003 through 31 December 2012. Our objective was to determine, via detection of the HWP1 gene, if any of the isolates were C. africana or C. dubliniensis. One and a half percent of these isolates (15/1014) were found to be C. africana, whereas C. dubliniensis was not detected. The 15 C. africana isolates were susceptible to nystatin, fluconazole, itraconazole, miconazole, and clotrimazole. Candida africana could not be recovered from clinical vaginal specimens from the 15 patients at follow-up on days 7-14 and days 30-35 when treated with different antifungal agents. We conclude that C. africana, but not C. dubliniensis, was present in the vaginal samples of patients with VVC. The C. africana isolates were susceptible to the tested antifungal agents. VVC caused by C. africana appears to respond well to current therapies. PMID:25023482

Prevalence and Treatment Management of Oropharyngeal Candidiasis in Cancer Patients: Results of the French Candidoscope Study  

International Nuclear Information System (INIS)

Purpose: The aim of this pharmaco-epidemiological study was to evaluate the prevalence of oropharyngeal candidiasis (OPC) in cancer patients treated with chemotherapy and/or radiotherapy. Methods and Materials: Signs and symptoms of OPC were noted for all patients. Antifungal therapeutic management was recorded in OPC patients. Patients receiving local antifungal treatments were monitored until the end of treatment. Results: Enrolled in the study were 2,042 patients with solid tumor and/or lymphoma treated with chemotherapy and/or another systemic cancer treatment and/or radiotherapy. The overall prevalence of OPC was 9.6% (95% confidence interval, 8.4%-11.0%] in this population. It was most frequent in patients treated with combined chemoradiotherapy (22.0%) or with more than two cytotoxic agents (16.9%). Local antifungal treatments were prescribed in 75.0% of OPC patients as recommended by guidelines. The compliance to treatment was higher in patients receiving once-daily miconazole mucoadhesive buccal tablet (MBT; 88.2%) than in those treated with several daily mouthwashes of amphotericin B (40%) or nystatin (18.8%). Conclusion: OPC prevalence in treated cancer patients was high. Local treatments were usually prescribed as per guidelines. Compliance to local treatments was better with once-daily drugs.

Successful treatment of hepatosplenic candidiasis in an elderly patient with acute myeloid leukemia using liposomal daunorubicin and fluconazole.  

Science.gov (United States)

Fungal infections are an increasing cause of morbidity and mortality in patients with haematological malignancies. The organism most often responsible are Candida spp., particurarly Candida Albicans. This report describes our experience in a 63-year-old man who developed symptoms of hepatosplenic candidiasis caused by Candida tropicalis after treatment for acute myeloid leukaemia (AML). The fungal infection was successfully controlled using fluconazole, and the patient has been disease-free for more than 11 months after antileukemic chemotherapy without any recurrence of Candida infections. Our experience suggests that AML and chemotherapy associated fungal infections can be controlled with an appropriate therapeutic regimen. PMID:11524268

Protocol for a randomised controlled trial of treatment of asymptomatic candidiasis for the prevention of preterm birth [ACTRN12610000607077  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Prevention of preterm birth remains one of the most important challenges in maternity care. We propose a randomised trial with: a simple Candida testing protocol that can be easily incorporated into usual antenatal care; a simple, well accepted, treatment intervention; and assessment of outcomes from validated, routinely-collected, computerised databases. Methods/Design Using a prospective, randomised, open-label, blinded-endpoint (PROBE study design, we aim to evaluate whether treating women with asymptomatic vaginal candidiasis early in pregnancy is effective in preventing spontaneous preterm birth. Pregnant women presenting for antenatal care The study protocol draws on the usual antenatal care schedule, has been pilot-tested and the intervention involves only a minor modification of current practice. Women who agree to participate will self-collect a vaginal swab and those who are culture positive for Candida will be randomised (central, telephone to open-label treatment or usual care (screening result is not revealed, no treatment, routine antenatal care. Outcomes will be obtained from population databases. A sample size of 3,208 women with Candida colonisation (1,604 per arm is required to detect a 40% reduction in the spontaneous preterm birth rate among women with asymptomatic candidiasis from 5.0% in the control group to 3.0% in women treated with clotrimazole (significance 0.05, power 0.8. Analyses will be by intention to treat. Discussion For our hypothesis, a placebo-controlled trial had major disadvantages: a placebo arm would not represent current clinical practice; knowledge of vaginal colonisation with Candida may change participants' behaviour; and a placebo with an alcohol preservative may have an independent affect on vaginal flora. These disadvantages can be overcome by the PROBE study design. This trial will provide definitive evidence on whether screening for and treating asymptomatic candidiasis in pregnancy significantly reduces the rate of spontaneous preterm birth. If it can be demonstrated that treating asymptomatic candidiasis reduces preterm births this will change current practice and would directly impact the management of every pregnant woman.

In leukopenic mice with severe systemic candidiasis, single-dose treatment (5 mg of amphotericin B [AMB]/kg of body weight) with long-circulating polyethylene glycol-coated AMB liposomes (PEG-AMB-LIP) resulted in zero mortality and a significant reduction in the number of viable Candida albicans in the kidney, whereas 70% mortality was seen in mice treated with five daily doses of AmBisome (5 mg of AMB/kg · day). When the first of five daily doses of AmBisome was combined with a single low d...

Evaluation of efficacy and safety of itraconazole oral solution for the treatment of oropharyngeal candidiasis in AIDS patients  

Digital Repository Infrastructure Vision for European Research (DRIVER)

This study was a non-comparative multicenter clinical trial to evaluate the efficacy and tolerability of itraconazole oral solution 200 mg/day (100 mg twice a day in the fasting state) for the treatment of oropharyngeal candidiasis in AIDS patients. We included 50 patients who were treated and followed for up to 3 weeks after ending therapy in the analysis. Mycological cures at the end of therapy occurred in 20/50 patients (40%), but colonization by Candida sp. was recorded in 42/50 (84%) by ...

Safety, tolerance, and pharmacokinetics of amphotericin B lipid complex in children with hepatosplenic candidiasis.  

Science.gov (United States)

The safety, tolerance, and pharmacokinetics of amphotericin B lipid complex (ABLC) were studied in a cohort of pediatric cancer patients. Six children with hepatosplenic candidiasis (HSC) received 2.5 mg of ABLC/kg of body weight/day for 6 weeks for a total dosage of 105 mg/kg. Mean serum creatinine (0.85 +/- 0.12 mg/dl at baseline) was stable at the end of therapy at 0.85 +/- 0.18 mg/dl and at 1-month follow-up at 0.72 +/- 0.12 mg/dl. There was no increase in hepatic transaminases. Mean plasma concentrations over the dosing interval (C(ave)) and area under the curve from 0 to 24 h (AUC(0-24h)) increased between the first and seventh doses but were similar between doses 7 and 42, suggesting that steady state was achieved by day 7 of therapy. Following the final (42nd) dose of ABLC, mean AUC(0-24h) was 11.9 +/- 2.6 microg h/ml, C(ave) was 0.50 +/- 0.11 microg/ml, maximum concentration of the drug in whole blood was 1.69 +/- 0.75 microg/ml, and clearance was 3.64 +/- 0.78 ml/min/kg. Response of hepatic and splenic lesions was monitored by serial computerized tomographic and magnetic resonance imaging scans. The five evaluable patients responded to ABLC with complete or partial resolution of physical findings and of lesions of HSC. During the course of ABLC infusions and follow-up, there was no progression of HSC, breakthrough fungemia, or posttherapy recurrence. Hepatic lesions continued to resolve after the completion of administration of ABLC. Thus, ABLC administered in multiple doses to children was safe, was characterized by a steady state attainable within 1 week of therapy, and was effective in treatment of HSC. PMID:9303390

A common mutation in Sardinian autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy patients.  

Science.gov (United States)

Autoimmune polyendocrinopathy-candidiasisectodermal dystrophy (APECED; also called APS-1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is characterized by two of the three major clinical symptoms that may be present: Addison's disease, and/or hypoparathyroidism and/or chronic mucocutaneous candidiasis. We have recently identified the gene for APECED, which we termed AIRE (for autoimmune regulator). AIRE is expressed in thymus, lymph nodes and fetal liver, and encodes a protein with two putative zinc fingers and other motifs suggestive of a transcriptional regulator. Seven mutations have been described to date, including R257X, the predominant Finnish and northern Italian APECED allele, which has also been observed in other patients of diverse origin on different haplotypes. A 13-bp deletion (1094-1106del) has also been observed in several patients of different geo-ethnic origin. The other described mutations appear to be rare. We present mutational analyses of the AIRE gene in ten Sardinian APECED families and show that there is a mutation, R139X, associated with one predominant haplotype unique to the Sardinian patients (18/20 independent alleles). The carrier frequency of R139X in Sardinia is 1.7%, giving an estimated population frequency of APECED of 1/14,400. Using linkage disequilibrium data, the estimated age of the R139X mutation is between 20 and 25 generations. A previously described 13-bp deletion was also observed on an allele of one patient. The identification of a single common Sardinian APECED mutation will facilitate its genetic diagnosis. Given the carrier frequency of R139X in the Sardinian population, AIRE may be implicated in the pathogenesis of other autoimmune diseases in the Sardinian population, particularly those affecting the endocrine system.

Econazole-polycarbophil, a new delivery system for topical therapy: microbiological and clinical results on vaginal candidiasis.  

Science.gov (United States)

The aim of this study was to demonstrate that the addition of a bioadhesive polymer to econazole, which increases the duration of the active drug at the site of infection, leads to a greater frequency of negative culture after treatment and probably reduces the recurrence rate of vaginal candidiasis.180 women with vaginal candidiasis were treated with 150 mg vaginal ovules econazole nitrate with (group A) or without (group B) polycarbophil. After 3 days of treatment the negative culture of Candida albicans reached 98.6% in group A and 84.8% in B group, while the overall persistence (C. albicans, C. glabrata, C. krusei, and C. parapsilosis) was 5.6% and 30%, respectively. During a 60-day follow-up, only one case out of 85 (1.2%) in group A reported recurrence while in group B there were 6 out of 63 (9.5%) recurrences. We conclude that, since the women were treated with the same amount of econazole, the better clinical and microbiological results can be attributed to polycarbophil, as confirmed by a significant reduction of recurrences.

Levamisole Aids in Treatment of Refractory Oral Candidiasis in Two Patients with Thymoma Associated with Myasthenia Gravis: Report of Two Cases  

Directory of Open Access Journals (Sweden)

Full Text Available Oral candidiasis is associated with defects in cell-mediated immunity and is commonamong patients undergoing cytotoxic chemotherapy, or corticosteroid or antibiotic therapy,and those patients seropositive for AIDS and HIV (human immunodeficiency virus. Thispaper demonstrates the important role of cell-mediated immunity in oral candidiasis in 2cases of thymoma associated with myasthenia gravis. Both suffered from recurrent oral candidiasisafter a thymectomy, radiotherapy, and chemotherapy. There was an initial goodresponse to conventional antifungal therapy, which later became refractory. Lymphocytesubset quantitation showed a T cell deficiency and a decreased CD4/CD8 ratio. Levamisole,an immunomodulator, or an immunopotentiating drug was added as adjunctive therapy incombination with oral nystatin treatment. Oral candidiasis responded favorably, and substantialrelief was obtained with a concurrent increase in T cells and the CD4/CD8 ratio.These findings clearly demonstrate a significant role of cell-mediated immunity in oral candidiasis,and that eradication of infection is dependent on the host defense mechanism.

[Effects of inhibitory activity on mycelial growth of Candida albicans and therapy for murine oral candidiasis by the combined use of terpinen-4-ol and a middle-chain fatty acid, capric acid].  

Science.gov (United States)

The combined effect of terpinen-4-ol, the main component of tea tree oil, and capric acid against mycelial growth of Candida albicans and murine oral candidiasis was evaluated in vitro and in vivo. Mycelial growth of C. albicans was estimated by the Cristal violet method. Combination of these compounds revealed a potent synergistic inhibition of growth. Therapeutic efficacy of the combination was evaluated microbiologically in murine oral candidiasis, and its application of the compounds clearly demonstrated therapeutic activity. Based on these results, the combined agent of terpinen-4-ol and capric acid was discussed as a possible candidate for oral candidiasis therapy. PMID:23292030

Beneficial effect of Mentha suaveolens essential oil in the treatment of vaginal candidiasis assessed by real-time monitoring of infection  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Vaginal candidiasis is a frequent and common distressing disease affecting up to 75% of the women of fertile age; most of these women have recurrent episodes. Essential oils from aromatic plants have been shown to have antimicrobial and antifungal activities. This study was aimed at assessing the anti-fungal activity of essential oil from Mentha suaveolens (EOMS in an experimental infection of vaginal candidiasis. Methods The in vitro and in vivo activity of EOMS was assessed. The in vitro activity was evaluated under standard CLSI methods, and the in vivo analysis was carried out by exploiting a novel, non-invasive model of vaginal candidiasis in mice based on an in vivo imaging technique. Differences between essential oil treated and saline treated mice were evaluated by the non-parametric Mann-Whitney U-test. Viable count data from a time kill assay and yeast and hyphae survival test were compared using the Student's t-test (two-tailed. Results Our main findings were: i EOMS shows potent candidastatic and candidacidal activity in an in vitro experimental system; ii EOMS gives a degree of protection against vaginal candidiasis in an in vivo experimental system. Conclusions This study shows for the first time that the essential oil of a Moroccan plant Mentha suaveolens is candidastatic and candidacidal in vitro, and has a degree of anticandidal activity in a model of vaginal infection, as demonstrated in an in vivo monitoring imaging system. We conclude that our findings lay the ground for further, more extensive investigations to identify the active EOMS component(s, promising in the therapeutically problematic setting of chronic vaginal candidiasis in humans.

Diagnosis of invasive candidiasis by enzyme-linked immunosorbent assay using the N-terminal fragment of Candida albicans hyphal wall protein 1  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The diagnosis of invasive candidiasis is difficult because there are no specific clinical manifestations of the disease and colonization and infection are difficult to distinguish. In the last decade, much effort has been made to develop reliable tests for rapid diagnosis of invasive candidiasis, but none of them have found widespread clinical use. Results Antibodies against a recombinant N-terminal fragment of the Candida albicans germ tube-specific antigen hyphal wall protein 1 (Hwp1 generated in Escherichia coli were detected by both immunoblotting and ELISA tests in a group of 36 hematological or Intensive Care Unit patients with invasive candidiasis and in a group of 45 control patients at high risk for the mycosis who did not have clinical or microbiological data to document invasive candidiasis. Results were compared with an immunofluorescence test to detect antibodies to C. albicans germ tubes (CAGT. The sensitivity, specificity, positive and negative predictive values of a diagnostic test based on the detection of antibodies against the N-terminal fragment of Hwp1 by immunoblotting were 27.8 %, 95.6 %, 83.3 % and 62.3 %, respectively. Detection of antibodies to the N-terminal fragment of Hwp1 by ELISA increased the sensitivity (88.9 % and the negative predictive value (90.2 % but slightly decreased the specificity (82.6 % and positive predictive values (80 %. The kinetics of antibody response to the N-terminal fragment of Hwp1 by ELISA was very similar to that observed by detecting antibodies to CAGT. Conclusion An ELISA test to detect antibodies against a recombinant N-terminal fragment of the C. albicans germ tube cell wall antigen Hwp1 allows the diagnosis of invasive candidiasis with similar results to those obtained by detecting antibodies to CAGT but without the need of treating the sera to adsorb the antibodies against the cell wall surface of the blastospore.

Low-dose ketoconazole-fluconazole combination versus fluconazole in single doses for the treatment of vaginal candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Vaginal candidiasis (VC is one of the most common fungal diseases. Candida albicans is the most common causative fungus and has been isolated from more than 80% of specimens obtained from women with VC. Ketoconazole is the first orally active antifungal, the dosage for VC is 200 mg twice daily for 5 days. Fluconazole is the newer oral antifungal, its dosage for VC is a single oral dose of 150 mg. Since fluconazole 150 mg is considerably expensive, a single dose of 100 mg ketoconazole and 40 mg fluconazole in combination has been tested for the treatment of VC. The results showed that from 11 women with confirmed VC, 1-2 weeks after drug administration, the mycological culture was negative in 8 women, positive in 1 woman, and 2 woman lost to follow-up. This promising result led to the present study with the objective to confirm the efficacy and safety of the above combination in a formal clinical trial.Methods: A total of 165 female patients, aged 18 years or older, with the diagnosis of VC from clinical symptoms (pruritus or burning or excessive discharge and positive microscopic smear (pseudohyphae and/or yeast cells were randomized to receive a single dose of either keto-fluco combination (n = 85 or fluconazole (n = 80, and returnedfor follow-up visit on day 8.Results: Among these patients, 39 patients had negative baseline culture, leaving 126 patients eligible for efficacy evaluation. The mycological eradication in the keto-fluco group was 74.5% (41 patients from a total of 55 patients with available mycological culture, while that in the fluconazole group was 70.2% (40 patients from 57 patients with available culture and this difference was not significant. The clinical favorable response (clinical cure and clinical improvement in the keto-fluco arm (n = 60 was 98.3%, while that in the fluconazole group (n = 66 was 100%. Adverse events were found in 5 patients, 3 patients in the keto-fluco group (3/85 = 3.5% and 2 patients in the fluconazole group (2/80 = 2.5%.Conclusion: The present study showed that the efficacy and safety of ketoconazole 100 mg and fluconazole 40 mg combination was not inferior compared to fluconazole 150 mg in single doses for the treatment of vaginal candidiasis. (Med J Indones 2011; 20:205-11Keywords: fluconazole, low-dose ketoconazole-fluconazole combination, single dose, vaginal candidiasis

Superior efficacy of liposomal amphotericin B with prolonged circulation in blood in the treatment of severe candidiasis in leukopenic mice.  

Science.gov (United States)

In leukopenic mice with severe systemic candidiasis, single-dose treatment (5 mg of amphotericin B [AMB]/kg of body weight) with long-circulating polyethylene glycol-coated AMB liposomes (PEG-AMB-LIP) resulted in zero mortality and a significant reduction in the number of viable Candida albicans in the kidney, whereas 70% mortality was seen in mice treated with five daily doses of AmBisome (5 mg of AMB/kg . day). When the first of five daily doses of AmBisome was combined with a single low dose of Fungizone (0.1 mg of AMB/kg), the efficacy was equal to that of PEG-AMB-LIP. PMID:9736577

Candida species in cutaneous candidiasis patients in the Guilan province in Iran; identified by PCR-RFLP method.  

Science.gov (United States)

Due to the epidemiological alteration in distribution of Candida species as well as significant increasing trend of either intrinsic or acquired in resistance of some of these fungi, the precise identification of Candida species is necessary for effective antifungal therapy and also for prevention of nosocomial infections. PCR-RFLP method is indicated to be a reliable, rapid and simple technique which is able to differentiate the Candida species. In the present study, we applied this method to evaluate the distribution of Candida species in patients affected with cutaneous candidiasis in the Guilan province. 896 clinical cutaneous samples were collected from different parts of skin and nail of suspected patients referred to clinical centers all over the Guilan province during 24 months. Samples were examined directly with 15% KOH and cultured on fungal specific media. Genomic DNA was extracted and the restriction enzyme Msp1 was applied for polymorphism analysis. Totally, 47 yeast strains were successfully isolated from different clinical samples and identified by conventional as well as PCR-RFLP methods. The results indicated that Candida albicans (36.17%) was the most frequent species followed by C. parapsilosis (25.53%), C. tropicalis (19.14%), C. guilliermondii (14.89%), C. famata (2.12%) and C. krusei (2.12%). Female finger nails were the most common location to be affected by Candida species. In conclusion, PCR-RFLP method was successfully used for recognition of clinical Candida species within the Guilan province and obtained results revealed C. albicans as the predominant causative agent of cutaneous candidiasis. However, distribution of other Candida species did not completely consist with the reported distribution of Candida species in other parts of Iran with different climate to the Guilan province.

Phenotypic Characterization and Antifungal Susceptibility Pattern to Fluconazole in Candida species Isolated from Vulvovaginal Candidiasis in a Tertiary Care Hospital  

Science.gov (United States)

Background: Vaginal candidiasis is a common gynecological finding among women worldwide. This study was carried out to determine the prevalence of vulvovaginal candidiasis (VVC) along with speciation of Candida with special reference to its antifungal susceptibility pattern to fluconazole and also to evaluate the risk factors responsible for VVC in patients attending our tertiary care hospital in Puducherry, India. Materials and Methods: This study was carried out in the tertiary care hospital in Puducherry during the period of August 2010 to September 2012.The study group consisted of 180 women between the age group of 15 to 56 years with the complaints of excessive vaginal discharge, pruritis and pain. Materials used for this study consisted of high vaginal swabs from patients with relevant history, attending Obstetrics & Gynecology department. High vaginal swabs were subjected to direct 10% KOH wet mount microscopy, Gram stain, culture onto Sabouraud’s dextrose agar (SDA) & 5% sheep blood agar and susceptibility testing to fluconazole was performed using E-test. Results: Candida was isolated in 40 (22.2 %) women & these consisted of C. albicans 26 (65%), C. glabrata 9 (22.5%), C.tropicalis 3 (7.5%) & C. parapsilosis 2 (5%). Susceptibility test carried out on the 40 isolates revealed that 35 (87.5%) Candida isolates were sensitive to fluconazole, 3 (7.5%) were moderately sensitive and 2 (2.5%) were resistant. Thirty one percent patients had itching as the presenting complaints followed by vaginal discharge (29.4%). Conclusion: The high frequency with which C. albicans was recovered in our study and its susceptibility to fluconazole supports the continued use of azole agents for empirical therapy of uncomplicated candidal vulvovaginitis in the community.

Histatin 5-spermidine conjugates have enhanced fungicidal activity and efficacy as a topical therapeutic for oral candidiasis.  

Science.gov (United States)

Oropharyngeal candidiasis (OPC) is caused by the opportunistic fungi Candida albicans and is prevalent in immunocompromised patients, individuals with dry mouth, or patients with prolonged antibiotic therapies that reduce oral commensal bacteria. Human salivary histatins, including histatin 5 (Hst 5), are small cationic proteins that are the major source of fungicidal activity of saliva. However, Hsts are rapidly degraded in vivo, limiting their usefulness as therapeutic agents despite their lack of toxicity. We constructed a conjugate peptide using spermidine (Spd) linked to the active fragment of Hst 5 (Hst 54-15), based upon our findings that C. albicans spermidine transporters are required for Hst 5 uptake and fungicidal activity. We found that Hst 54-15-Spd was significantly more effective in killing C. albicans and Candida glabrata than Hst 5 alone in both planktonic and biofilm growth and that Hst 54-15-Spd retained high activity in both serum and saliva. Hst 54-15-Spd was not bactericidal against streptococcal oral commensal bacteria and had no hemolytic activity. We tested the effectiveness of Hst 54-15-Spd in vivo by topical application to tongue surfaces of immunocompromised mice with OPC. Mice treated with Hst 54-15-Spd had significant clearance of candidal tongue lesions macroscopically, which was confirmed by a 3- to 5-log fold reduction of C. albicans colonies recovered from tongue tissues. Hst 54-15-Spd conjugates are a new class of peptide-based drugs with high selectivity for fungi and potential as topical therapeutic agents for oral candidiasis. PMID:24247141

Correlation Between HIV and Sexual Behavior, Drug Use, Trichomoniasis and Candidiasis Among Female Sex Workers in a Mekong Delta Province of Vietnam  

Science.gov (United States)

To determine the prevalence of HIV and correlates of HIV infection among female sex workers (FSWs) in Soc Trang province, Vietnam, a survey of 406 FSWs in Soc Trang province was conducted between May and August, 2003. The participants were interviewed, using a standardized interview, to obtain information about sociodemographic and behavioral characteristics, and gynecologic and sexually transmitted infection (STI) history. The prevalence of HIV was 3.3%. An increased risk for HIV was associated with ever using illicit drugs, direct sex work, early sexual debut, age of FSWs, and infection with candidiasis and trichomoniasis. Reduced likelihood of HIV was only associated with withdrawal as a contraceptive method. A strong association of HIV with drug use and candidiasis and trichomoniasis infection among FSWs was found. Needle/syringe exchange, STI treatment, and methadone programs targeting FSWs should be implemented, and should include 100% condom use promotion.

[Treatment of hepatosplenic candidiasis with liposomal amphotericin B in a patient with acute leukemia; a case report of the experience of use of liposomal amphotericin B].  

Science.gov (United States)

We report a 26-year-old male patient with acute myelocytic leukemia and hepatosplenic candidiasis during his clinical course. His hepatosplenic candidiasis was refractoty to itraconazole and fluconazol. He developed serious side-effect such as renal dysfunction, when conventional amphotericin B was given. Then he was treated with liposomal amphotericin B (Abelcet). This therapy was safe and effective for him. He was able to be treated with 3075 mg of a liposomal amphotericin B. This was ten times as much as the dose of conventional amphotericin B which was given earlier until amphotericin B was stopped because of renal dysfunction. Liposomal amphotericin B seems to be a safe and effective therapy for systemic fungal infectin and should be considered more in Japan. PMID:9695475

Successful intensive chemotherapy followed by autologous hematopoietic cell transplantation in a patient with acute myeloid leukemia and hepatosplenic candidiasis: case report and review of literature.  

Science.gov (United States)

Hepatosplenic candidiasis (HSC) in patients with acute leukemia poses management challenges because the therapeutic limitations of the present antifungal armamentarium may adversely impact on treatment outcomes of the underlying leukemia. We report a patient with acute myeloid leukemia who developed HSC during post-remission consolidation chemotherapy and was treated with a prolonged course of caspofungin followed by fluconazole. The stabilization of infection permitted further chemotherapy and autologous hematopoietic cell transplant (HCT) without breakthrough fungemia and further dissemination of candidiasis. The favorable outcome provides further evidence that with optimal treatment, the presence of stable or non-progressive HSC is not an absolute contraindication for HCT. The use of caspofungin in the primary treatment of HSC appears to be a promising approach. The favorable outcome seen in this case is encouraging, although further study on its efficacy is warranted.

The Secreted Aspartyl Proteinases Sap1 and Sap2 Cause Tissue Damage in an In Vitro Model of Vaginal Candidiasis Based on Reconstituted Human Vaginal Epithelium  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Secreted aspartyl proteinases (Saps) contribute to the ability of Candida albicans to cause mucosal and disseminated infections. A model of vaginal candidiasis based on reconstituted human vaginal epithelium (RHVE) was used to study the expression and role of these C. albicans proteinases during infection and tissue damage of vaginal epithelium. Colonization of the RHVE by C. albicans SC5314 did not cause any visible epithelial damage 6 h after inoculation, although expression of SAP2, SAP9, ...

Limited Role of Secreted Aspartyl Proteinases Sap1 to Sap6 in Candida albicans Virulence and Host Immune Response in Murine Hematogenously Disseminated Candidiasis?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Candida albicans secreted aspartyl proteinases (Saps) are considered virulence-associated factors. Several members of the Sap family were claimed to play a significant role in the progression of candidiasis established by the hematogenous route. This assumption was based on the observed attenuated virulence of sap-null mutant strains. However, the exclusive contribution of SAP genes to their attenuated phenotype was not unequivocally confirmed, as the Ura status of these mutant strains could ...

Liquiritigenin, a licorice flavonoid, helps mice resist disseminated candidiasis due to Candida albicans by Th1 immune response, whereas liquiritin, its glycoside form, does not.  

Science.gov (United States)

Licorice (the root of Glycyrrhizae plant) has been used as an oriental herbal medicine for thousands of years. The licorice flavonoid components are reported to possess immunomodulatory activities. In this present study, we investigated the immunomodulatory effects of liquiritigenin (LG) and liquiritin (LQ), licorice flavonoid components, against disseminated candidiasis due to Candida albicans, a dimorphic fungus, that causes severe disease via hematogenous dissemination and local diseases such as vaginitis and thrush. Results showed that direct interaction of LG or LQ with C. albicans yeast cells resulted in no growth-inhibition, in vitro. When tested in a murine model of disseminated candidiasis, mice given LQ intraperitoneally before intravenous challenge with live C. albicans yeast cells had similar mean survival times (MST) as untreated mice groups. On the contrary, mice given LG in the same manner as LQ above had longer MST than the untreated mice groups (P < 0.05). In one experiment, 3 out of 5 LG-treated mice survived during the entire period of the 55-day observation. Furthermore, the 3 survivors were cured -- shown by a lack of CFU (colony forming unit) in the kidneys. This protection was nulled when mice were pretreated with anti-CD4+ antibody before LG-treatment and challenge with the yeast. However, the protection was transferable by the CD4+ T cells isolated from LG-treated mice not infected with the yeast. In addition, mice given CD4+ T cells that were pre-treated with LG, in vitro were also protected against disseminated candidiasis. ELISA analysis revealed that in LG-treated mice IFNgamma and IL-2 were dominantly produced compared to IL-4 and IL-10. When LG-given mice were treated with anti-mouse IFNgamma, the protection was again nulled. Combined together, these results indicate that LG protects mice against disseminated candidiasis by the CD4+ Th1 immune response. PMID:19264152

Sexually transmitted infections, bacterial vaginosis, and candidiasis in women of reproductive age in rural Northeast Brazil: a population-based study  

Directory of Open Access Journals (Sweden)

Full Text Available Population-based data on sexually transmitted infections (STI, bacterial vaginosis (BV, and candidiasis reflect the epidemiological situation more accurately than studies performed in specific populations, but such data are scarce. To determine the prevalence of STI, BV, and candidiasis among women of reproductive age from a resource-poor community in Northeast Brazil, a population-based cross sectional study was undertaken. All women from seven hamlets and the centre of Pacoti municipality in the state of Ceará, aged 12 to 49 years, were invited to participate. The women were asked about socio-demographic characteristics and genital symptoms, and thereafter examined gynaecologically. Laboratory testing included polymerase chain reaction (PCR for human papillomavirus (HPV, ligase chain reaction (LCR for Chlamydia trachomatis and Neisseria gonorrhoeae, ELISA for human immunodeficiency virus (HIV, venereal disease research laboratory (VDRL and fluorescent treponema antibody absorption test (FTA-ABS for syphilis, and analysis of wet mounts, gram stains and Pap smears for trichomoniasis, candidiasis, and BV. Only women who had initiated sexual life were included in the analysis (n = 592. The prevalences of STI were: HPV 11.7% (95% confidence interval: 9.3-14.7, chlamydia 4.5% (3.0-6.6, trichomoniasis 4.1% (2.7-6.1, gonorrhoea 1.2% (0.5-2.6, syphilis 0.2% (0.0-1.1, and HIV 0%. The prevalence of BV and candidiasis was 20% (16.9-23.6 and 12.5% (10.0-15.5, respectively. The most common gynaecological complaint was lower abdominal pain. STI are common in women in rural Brazil and represent an important health threat in view of the HIV pandemic.

Anti-candidal activity of Astragalus verus in the in vitro and in vivo guinea pig models of cutaneous and systemic candidiasis  

Directory of Open Access Journals (Sweden)

Full Text Available This study was design to evaluate the anti-candidal activity of Astragalus verus Olivier, Fabaceae (Av. The GC/MS analysis of essential oils of Av showed that aqueous extract contains thymol while hexadecanoic acid, 1,2-benzenedicarboxylic acid, diisooctyl ester and phytol were found as major components of methanol and acetone extracts. The aqueous extract showed anti-candidal activity in the concentration 320 mg/mL using disc diffusion method and its minimum inhibitory concentration (MIC was 160 mg/mL. To induce cutaneous candidiasis, the dorsum of immunocompromised guinea pigs was infected with Candida albicans and animals were divided into five groups (n=5 for each: NC, received a vehicle; PC, received topical ketoconazole 2% and three other groups which received topical 10, 20 and 40% aqueous extract of Av. On ninth day postinfection, skins were cultured and colony forming unite per gram (CFU/g skin was recorded. Systemic candidiasis was obtained by intravenous inoculation of C. albicans, 4000 CFU/g body weight. Here, animals have been divided into five groups like cutaneous candidiasis but their medications have been delivered in drinking water for ten days before induction of infection. On second day postinfection, all internal tissues were taken for determining CFU/g tissue. The aqueous extract (40% prevented heavy burden of C. albicans in tissues and skin in oral and topical application, respectively. The results indicate that Av represents a potential source of anti-candidal drug.

Factors related to survival and treatment success in invasive candidiasis or candidemia: a pooled analysis of two large, prospective, micafungin trials.  

Science.gov (United States)

Crude and attributable mortality rates in patients with candidemia and invasive candidiasis remain unacceptably high. It is important to reach a more complete understanding of the risk factors underlying poor outcomes in patients with invasive Candida infections. Micafungin therapy has been assessed in two phase 3 trials compared to either liposomal amphotericin B or caspofungin. The availability of this large dataset allows the analyses of non-drug factors associated with survival and treatment success. A multivariate regression analysis was performed on data from the two trials separately and as a pooled analysis (N = 1,070). Analysis outcomes were survival at 42 days post-initiation of therapy and treatment success. For the pooled analysis, treatment success was significantly more likely for candidemia than invasive candidiasis. Both survival and treatment success were significantly less likely for the non-removal of catheter versus removal, Asian-Indians versus Caucasians, APACHE II score >20 to 30 versus or=70 years versus <50 years, baseline corticosteroids, and persistent neutropenia. Survival was also significantly less likely for treatment in other regions versus North America and for patients with renal failure at baseline. These findings help to define non-antifungal drug factors that may impact survival and treatment success in invasive candidiasis or candidemia. PMID:20013016

Candidiasis and other oral mucosal lesions during and after interferon therapy for HCV-related chronic liver diseases  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Oral lichen planus (OLP is seen frequently in patients with hepatitis C virus (HCV infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN therapy for HCV infection. Methods Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. Results Cultures of Candida from the tongue surfaces were positive in 7 (50.0% of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14 of patients: OLP in three (21.4%, angular cheilitis in three (21.4% and recurrent aphthous stomatitis in one (7.1%. OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1 and the 7 patients in whom Candida was not detected during IFN therapy (group 2. The prevalence of oral mucosal lesions (P=0.0075 and incidence of external use of steroids (P=0.0308 in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088. Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0.0550. According to multivariate analysis, one factor, the presence of oral mucosal lesions, was associated with the detection of Candida. The adjusted odds ratio for the factor was 36.00 (95% confidence interval 2.68-1485.94. Conclusion We should pay more attention to oral candidiasis as well as other oral mucosal lesions, in patients with weight loss during IFN treatment.

Economic evaluation of micafungin vs. liposomal amphotericin B (LAmB) for the treatment of candidaemia and invasive candidiasis (IC).  

Science.gov (United States)

Micafungin was non-inferior to liposomal amphotericin B (LAmB) for the treatment of candidaemia and invasive candidiasis (IC) in a major clinical trial. The present study investigated the economic impact of micafungin vs. LAmB in treating candidaemia and IC. A decision analytical model was constructed to capture downstream consequences of using micafungin or LAmB as primary definitive therapy. The main outcomes were treatment success and treatment failure due to mycological persistence, or death. Outcome probabilities were derived from key published sources. Resource used was estimated by an expert panel and cost inputs were from the latest Australian resources. The analysis was from an Australian hospital perspective. Sensitivity analyses using Monte Carlo simulation were conducted. Micafungin (AU$61 426) had a lower total cost than LAmB (AU$72 382), with a total net cost-saving of AU$10 957 per patient. This was primarily due to the lower cost associated with initial antifungal treatment and shorter length of stay for patients in the micafungin arm. Hospitalisation was the main cost driver for both arms. Results were robust over a wide range of variables. The uncertainty analysis demonstrated that micafungin had a 99.9% chance of being cost-saving compared with LAmB. Micafungin was associated with cost-saving relative to LAmB in the treatment of candidaemia and IC in Australia. PMID:23496163

Formulation and evaluation of a novel mucoadhesive drug delivery system to treat intestinal candidiasis in immunocompromised patients  

Directory of Open Access Journals (Sweden)

Full Text Available The limited solubility, and therefore bioavailability, of the antimycotic drug,itraconazole, used for the treatment of intestinal Candidiasis in immunocompromisedindividuals, has been well documented. Therapeutic regimen in these patients mayinclude daily administration of multiple doses of various drugs. Hence, improving theresidence time of therapeutic agents, would ensure a high continuous concentration inthe body and help decrease the dosing frequency. In our current study, we haveinvestigated a novel method of drug delivery, developed by utilizing the concept ofmucoadhesiveness, for the sustained release of the drug, itraconazole. Mucoadhesivebeads were prepared using two natural polymers, isabghula husk and alginate. Theminimum inhibitory concentration of itraconazole for Candida was found to be1.5milligram per millilitre. Accordingly, beads were prepared by ionic gelation methodusing calcium chloride as a crosslinking agent. Marked improvement in solubility of thedrug was noted after entrapment. Prepared beads were subjected to various evaluationsincluding particle size, swelling behaviour and mucoadhesivity. At pH 7.4, goodmucoadhesive property was exhibited up to 7 hours. Maximum swelling of beads wasobserved at 4hours in phosphate buffer after which the beads showed slight erosion.Fresh cock intestinal mucosa was used to assess the sustained release of itraconazolefrom the drug loaded beads and the reduction in candidal cells adhering to the mucosawas verified by the viable count technique. The results of our present study indicate thatmucoadhesive intestinal retentive isabghula- alginate beads could represent a promisingvehicle for drug delivery and help improve therapeutic efficacy and patient compliancein the future.

Oropharyngeal candidiasis with dry-powdered fluticasone propionate: 500 microg/day versus 200 microg/day.  

Science.gov (United States)

We aimed to determine the frequency of oropharyngeal candidiasis and its clinical correlates in the asthmatic patients who use fluticasone propionate (FP) as a dry powdered inhaler. We selected four groups of patients: 62 asthmatic patients who were taking 200 microg/d FP, 122 asthmatics who were taking 500 microg/d FP, 50 asthmatic patients who had not been on inhaled corticosteroid (ICS) treatment and 40 normal non-asthmatic subjects. The frequency of positive swabs for Candida colonization was higher in 500 microg/d FP group than asthmatics without ICS use (chi2 = 6.8, p < 0.05) and normal controls (chi2 = 4.9, p < 0.05), whereas it wasn't different in the 200 microg/day FP group when compared to controls. When we considered patients who used ICS, the most effective variables affecting the occurrence of Candida colonization were washing of the throat by the patients (OR = 9.4, 95 % Confidence Interval [CI] = 3.9-22.7, p < 0.0001) and duration of ICS use more than 12 months (OR = 2.5, 95 % CI = 1.1-2.6, p < 0.05). The present study showed that in the patients who use ICS, the most important determinants on colonization were not washing the throat regularly and duration of ICS use for more than 12 months.

Diagnosis and monitoring response to treatment of hepatosplenic candidiasis in patients with acute leukemia using magnetic resonance imaging.  

Science.gov (United States)

Hepatosplenic candidiasis (HSC) is a morbid complication encountered in immunocompromised individuals, especially, those being treated with intensive chemotherapy protocols for acute leukemia. Immediate recognition of this complication and initiation of appropriate treatment is crucial in order to control the infection, decrease the morbidity and mortality, and avoid delays in treatment of the underlying condition. The definitive diagnosis requires either positive blood cultures for yeasts in the presence of abnormal findings on imaging studies consistent with HSC, or liver biopsy demonstrating yeast forms or pseudohyphae. We describe our experience in the evaluation of 15 patients with HSC using magnetic resonance imaging (MRI) as a diagnostic and follow-up tool. The diagnosis of HSC was established by liver biopsy in 11 patients (73%), and by positive blood cultures for Candida in 4 patients (27%). All patients had MRI findings consistent with HSC during the study period. Amphotericin B was administered intravenously to all 15 patients (median duration of treatment, 62 days). Repeat MR images were obtained at 2 weeks, 6 weeks and then at monthly intervals until the resolution of abnormalities. The median time for the disappearance of MRI lesions was 9 weeks. Alterations in the appearance of lesions on MRI were noted throughout chemotherapy in all the 13 (86.6%) responding patients. Our results suggest that MRI when used in patients with high clinical suspicion for HSC provide an alternative for liver biopsy or other invasive diagnostic procedures and that appropriate response to treatment can be safely monitored by obtaining sequential MRI studies.

Gain-of-function human STAT1 mutations impair IL-17 immunity and underlie chronic mucocutaneous candidiasis.  

Science.gov (United States)

Chronic mucocutaneous candidiasis disease (CMCD) may be caused by autosomal dominant (AD) IL-17F deficiency or autosomal recessive (AR) IL-17RA deficiency. Here, using whole-exome sequencing, we identified heterozygous germline mutations in STAT1 in 47 patients from 20 kindreds with AD CMCD. Previously described heterozygous STAT1 mutant alleles are loss-of-function and cause AD predisposition to mycobacterial disease caused by impaired STAT1-dependent cellular responses to IFN-?. Other loss-of-function STAT1 alleles cause AR predisposition to intracellular bacterial and viral diseases, caused by impaired STAT1-dependent responses to IFN-?/?, IFN-?, IFN-?, and IL-27. In contrast, the 12 AD CMCD-inducing STAT1 mutant alleles described here are gain-of-function and increase STAT1-dependent cellular responses to these cytokines, and to cytokines that predominantly activate STAT3, such as IL-6 and IL-21. All of these mutations affect the coiled-coil domain and impair the nuclear dephosphorylation of activated STAT1, accounting for their gain-of-function and dominance. Stronger cellular responses to the STAT1-dependent IL-17 inhibitors IFN-?/?, IFN-?, and IL-27, and stronger STAT1 activation in response to the STAT3-dependent IL-17 inducers IL-6 and IL-21, hinder the development of T cells producing IL-17A, IL-17F, and IL-22. Gain-of-function STAT1 alleles therefore cause AD CMCD by impairing IL-17 immunity. PMID:21727188

Immunological findings in patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) and their family members: are heterozygotes subclinically affected?  

Science.gov (United States)

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; APS-1) is an autosomal recessive autoimmune disease, caused by mutations in the AIRE (autoimmune regulator) gene. Due to the proposed role of AIRE in central immune tolerance, the immune investigation of four females diagnosed with APECED, their siblings, parents and 14 age-matched controls was performed. The parameters analyzed included immunoglobulins, autoantibodies, cellular immunity and production of cytokines IFNgamma, IL-4 and IL-10, reflecting Th1xTh2 balance. Low IFNgamma levels (455 +/- 191 pg/ml) were detected in all affected girls compared to controls (910 +/- 406 pg/ml). Two girls with homozygous R257X mutations showed similarly marked elevation of IgM and increase of CD3+CD4+ lymphocytes. Positive autoantibodies against smooth muscle were found in one affected girl; another girl and her mother had antibodies against gastric parietal cells. Interestingly, all fathers had dramatically elevated levels of IgA and activated T lymphocytes. High frequency of abnormal immune results among parents is a novel finding which might suggest a subclinical immune deficit in heterozygotes with AIRE mutations. PMID:12503856

Gain-of-function human STAT1 mutations impair IL-17 immunity and underlie chronic mucocutaneous candidiasis  

Science.gov (United States)

Chronic mucocutaneous candidiasis disease (CMCD) may be caused by autosomal dominant (AD) IL-17F deficiency or autosomal recessive (AR) IL-17RA deficiency. Here, using whole-exome sequencing, we identified heterozygous germline mutations in STAT1 in 47 patients from 20 kindreds with AD CMCD. Previously described heterozygous STAT1 mutant alleles are loss-of-function and cause AD predisposition to mycobacterial disease caused by impaired STAT1-dependent cellular responses to IFN-?. Other loss-of-function STAT1 alleles cause AR predisposition to intracellular bacterial and viral diseases, caused by impaired STAT1-dependent responses to IFN-?/?, IFN-?, IFN-?, and IL-27. In contrast, the 12 AD CMCD-inducing STAT1 mutant alleles described here are gain-of-function and increase STAT1-dependent cellular responses to these cytokines, and to cytokines that predominantly activate STAT3, such as IL-6 and IL-21. All of these mutations affect the coiled-coil domain and impair the nuclear dephosphorylation of activated STAT1, accounting for their gain-of-function and dominance. Stronger cellular responses to the STAT1-dependent IL-17 inhibitors IFN-?/?, IFN-?, and IL-27, and stronger STAT1 activation in response to the STAT3-dependent IL-17 inducers IL-6 and IL-21, hinder the development of T cells producing IL-17A, IL-17F, and IL-22. Gain-of-function STAT1 alleles therefore cause AD CMCD by impairing IL-17 immunity.

A Supplement Based on Zn-Enriched Virgin Coconut Oil as an Antifungal agent for Vaginal Candidiasis Patients  

Directory of Open Access Journals (Sweden)

Full Text Available This research was conducted to investigate the amount of Candida albicans in vaginal secretion of Vaginal Candidiasis patients administered with Zn-enriched virgin coconut oil. Thirty respondents were selected based on several criteria as follows: the number of C. albicans colonies in the vaginal secretion was more than 105 cfu.ml-1, voluntary, healthy, willing to sign the informed consent and resided in Purwokerto. In Group A, 10 women were administered 2 tablespoons per day of Zn-enriched virgin coconut oil. In Group B, 10 women were administered 1 tablespoon per day of Zn-enriched virgin coconut oil; and in Group C, 10 women served as control group. Vaginal secretions were taken 3 times, before intervention (at baseline time, at 1 month and 2 months after intervention. Samples were taken by collecting vaginal secretions from the vaginal proximal region using a sterile cotton bud, which was then put into a tube containing sterile carrier media. The vaginal secretions were tested for the number of total C. albicans using Pour Plate Method. Two months after treatment, the number of colonies decreased from 4.4x106 to 2.5x106 cfu ml-1 (p=0.03 in Group A. There was no significant difference in the number of colonies between Group A and Group B, the number of C. albicans colonies was still above the normal range. Therefore, the recommended dosage of intervention with Zn-enriched virgin coconut oil is one tablespoon a day.

Anti-candidal activity of Astragalus verus in the in vitro and in vivo guinea pig models of cutaneous and systemic candidiasis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english This study was design to evaluate the anti-candidal activity of Astragalus verus Olivier, Fabaceae (Av). The GC/MS analysis of essential oils of Av showed that aqueous extract contains thymol while hexadecanoic acid, 1,2-benzenedicarboxylic acid, diisooctyl ester and phytol were found as major compo [...] nents of methanol and acetone extracts. The aqueous extract showed anti-candidal activity in the concentration 320 mg/mL using disc diffusion method and its minimum inhibitory concentration (MIC) was 160 mg/mL. To induce cutaneous candidiasis, the dorsum of immunocompromised guinea pigs was infected with Candida albicans and animals were divided into five groups (n=5 for each): NC, received a vehicle; PC, received topical ketoconazole 2% and three other groups which received topical 10, 20 and 40% aqueous extract of Av. On ninth day postinfection, skins were cultured and colony forming unite per gram (CFU/g) skin was recorded. Systemic candidiasis was obtained by intravenous inoculation of C. albicans, 4000 CFU/g body weight. Here, animals have been divided into five groups like cutaneous candidiasis but their medications have been delivered in drinking water for ten days before induction of infection. On second day postinfection, all internal tissues were taken for determining CFU/g tissue. The aqueous extract (40%) prevented heavy burden of C. albicans in tissues and skin in oral and topical application, respectively. The results indicate that Av represents a potential source of anti-candidal drug.

Abstract in english After a literature revision it is confirmed that the larynx candidiasis is rare and usually associated with lungs infection or systemic candidiasis. The larynx isolated form is more rare and seldom associated to immunological disease. It is known that through endoscopic examination, the candidiasis [...] of larynx can show a single local erythema or leucoplasy, simulating G.E.R.D. or even neoplasia, which are the main differential diagnosis. We reported in our hospital an immunocompetent patient with isolated laryngeal candidiasis. There was an important involvement of larynx with degenerative lesions on epyglote, simulating a neoplasic process. The diagnosis was confirmed by biopses and histophatologic analyses. We crossed off hypotheses corticosteroids and antibiotics abuse. We followed up during and after the treatment with antifungeal by the use of endoscopic and clinical improvement.

Use of Quantitative Real-Time PCR To Study the Kinetics of Extracellular DNA Released from Candida albicans, with Implications for Diagnosis of Invasive Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Quantitative real-time PCR (qPCR) is considered one of the most sensitive methods to detect low levels of DNA from pathogens in clinical samples. To improve the design of qPCR for the detection of deeply invasive candidiasis, we sought to develop a more comprehensive understanding of the kinetics of DNA released from Candida albicans in vitro and in vivo. We developed a C. albicans-specific assay targeting the rRNA gene complex and studied the kinetics of DNA released from C. albicans alone, ...

Enzymatic activity profile of a Brazilian culture collection of Candida albicans isolated from diabetics and non-diabetics with oral candidiasis.  

Science.gov (United States)

The secretion of hydrolytic enzymes is a fundamental virulence factor of Candida albicans to develop disease. The objective of this study was to characterise the virulence of 148 clinical isolates of C. albicans from oral candidiasis by assessing the expression of phospholipase (PL) and secreted aspartyl proteinase (SAP). Isolates were obtained from healthy subjects (HS) and diabetics (DOC) and non-diabetics with oral candidiasis (NDOC). An aliquot (5 ?l) of each cell suspension was inoculated on PL and SAP agar plates and incubated. Enzymes secretion was detected by the formation of an opaque halo around the colonies and enzymatic activity (PZ) was determined by the ratio between colony diameter and colony diameter plus the halo zone. Statistical comparisons were made by a one-way anova followed by Tukey's post hoc test (? = 0.05). The clinical sources of C. albicans had significant effect (P < 0.001) on the PZ values of both enzymes. For PL, clinical isolates from NDOC and DOC had highest enzymatic activity than those from HS (P < 0.05), with no significant differences between them (P = 0.506). For SAP, C. albicans from NDOC showed the lower enzymatic activity (P < 0.001). There were no significant differences between isolates from HS and DOC (P = 0.7051). C. albicans isolates from NDOC and DOC patients showed an increased production of PL. PMID:24329754

Anidulafungin compared with fluconazole for treatment of candidemia and other forms of invasive candidiasis caused by Candida albicans: a multivariate analysis of factors associated with improved outcome  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Abstract Background Candida albicans is the most common cause of candidemia and other forms of invasive candidiasis. Systemic infections due to C. albicans exhibit good susceptibility to fluconazole and echinocandins. However, the echinocandin anidulafungin was recently demonstrated to be more effective than fluconazole for systemic Candida infections in a randomized, double-blind trial among 245 patients. In that trial, most infections were caused ...

MSG-01: A Randomized, Double-Blind, Placebo-Controlled Trial of Caspofungin Prophylaxis Followed by Preemptive Therapy for Invasive Candidiasis in High-Risk Adults in the Critical Care Setting.  

Science.gov (United States)

Background.?Invasive candidiasis is the third most common bloodstream infection in the intensive care unit (ICU) and is associated with morbidity and mortality. Prophylaxis and preemptive therapy are attractive strategies for this setting. Methods.?We conducted a multicenter, randomized, double-blind, placebo-controlled trial of caspofungin as antifungal prophylaxis in 222 adults who were in the ICU for at least 3 days, were ventilated, received antibiotics, had a central line, and had 1 additional risk factor (parenteral nutrition, dialysis, surgery, pancreatitis, systemic steroids, or other immunosuppressants). Subjects' (1,3)-?-d-glucan levels were monitored twice weekly. The primary endpoint was the incidence of proven or probable invasive candidiasis by EORTC/MSG criteria in patients who did not have disease at baseline. Patients who had invasive candidiasis were allowed to break the blind and receive preemptive therapy with caspofungin. The preemptive approach analysis included patients all patients who received study drug, including those positive at baseline. Results.?The incidence of proven/probable invasive candidiasis in the placebo and caspofungin arms was 16.7% (14/84) and 9.8% (10/102), respectively, for prophylaxis (P = .14), and 30.4% (31/102) and 18.8% (22/117), respectively, for the preemptive approach (P = .04); however, this analysis included patients with baseline disease. There were no significant differences in the secondary endpoints of mortality, antifungal use, or length of stay. There were no safety differences. Conclusions.?Caspofungin was safe and tended to reduce the incidence of invasive candidiasis when used for prophylaxis, but the difference was not statistically significant. A preemptive therapy approach deserves further study. Clinical Trials Registration.?NCT00520234. PMID:24550378

Assessment of Aspergillus-specific T cells for diagnosis of invasive aspergillosis in a leukemic child with liver lesions mimicking hepatosplenic candidiasis.  

Science.gov (United States)

A child with acute myeloid leukemia presented with multiple liver lesions mimicking hepatosplenic candidiasis during the neutropenic phase following the induction chemotherapy. All the available diagnostic tools showed repeatedly negative results, including galactomannan. An enzyme-linked immunospot (ELISPOT) assay showed a high number of Aspergillus-specific T cells producing interleukin-10 [TH2(IL-10)] and a low number of Aspergillus-specific T cells producing gamma interferon [TH1(IFN-gamma)], revealing invasive aspergillosis (IA) before the confirmatory biopsy. A progressive skewing from the predominance of TH2(IL-10) to a predominance of TH1(IFN-gamma) was observed close to the complete resolution of the infection and foreshadowed the outcome. The ELISPOT assay holds promise for diagnosing pediatric IA. PMID:18667632

Incidence of Vaginal Candidiasis in Leucorrhoea in Women Attending in OPD of Gynecology and Obstetrics, Department, Gurugobind Singh Hospital, Jamnagar, Gujarat, India  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Candida is the most common agent causing leucorrhoea affecting the women of all strata. It is becoming difficult to completely eradicate the infection mainly due to recurrence caused by non-albican species of Candida. Most of the non-albican species of Candida are resistant to commonly used antifungal agent - azole. Therefore, studying the Incidence of Candida species in vaginal secretion is of great significance. Objective: To study the incidence of Candidiasis in patients of leucorrhoea and identification of different species of candida found in leucorrhoea and to study the effect of pregnancy and age on infection rate in women Attending  in OPD of Gynecology and Obstetrics, Department, Gurugobind Singh Hospital, Jamnagar, Gujarat, India. Materials and Methods: The study was conducted on 300 patients with specific complaints of leucorrhea. Discharge was examined by direct wet preparation by KOH mount, Gram staining, and Culture on Sabouraud’s dextrose agar. Species differentiation was done by Germ tube formation, Sugar assimilation and Sugar Fermentation test. Results: In 19% of the women the leucorrhea was due to Candida infection with highest incidence in women of age (21-30 years. Incidence of candidiasis was higher in Pregnant(22.5% compared to non-pregnant(16.6%. Candida albicans was the most common strain identified and Candida krusei was the least common one. Conclusion: Highest incidence found between 21-30 years age group, in pregnant women, in women from lower socio-economic class. Among candida species C.albicans was commonest followed by C.glabrata, C.tropicalis, C.krusei.

Trata-se de um meio terapêutico que apresenta como vantagem sobre as medicações alopáticas o fato de apresentar reações adversas mínimas. A Uncaria tomentosa é uma planta indígena da floresta Amazônica e de outras áreas [...] tropicais da América do Sul e Central. Tem aplicação no tratamento de diversas patologias, entre elas a candidose. Este trabalho avalia clínico e laboratorialmente a ação do gel da Uncaria tomentosa em pacientes portadores de candidose na cavidade oral. Foram selecionados 20 pacientes que apresentaram clínico e laboratorialmente infecção pelo Candida. Os mesmos foram divididos em 2 grupos. O grupo-teste (Uncaria tomentosa/Imuno-Max Gel), composto por 10 pacientes, foi orientado a utilizar o gel da Uncaria tomentosa, sobre as lesões na cavidade oral, 3x ao dia por um período de 14 dias. O grupo-controle (Miconazol/Daktarin Gel) utilizou a medicação da mesma forma prescrita para o grupo-teste. Após o período de tratamento, os pacientes retornaram para nova avaliação clínica e laboratorial. A Uncaria tomentosa mostrou ser um fitofármaco promissor na odontologia, apresentando vantagem sobre o miconazol de não ter provocado reações adversas nos pacientes, uma vez que, 40% dos pacientes do grupo-controle, apresentaram reações indesejáveis. Abstract in english In dentistry, the phytotherapy is already being used successfully for some years now. It is about a promising therapeutical way in the pharmaceutical field, having as advantage on pharmacotherapy medications the fact to present minimum adverse reactions. The Uncaria tomentosa is an aboriginal plant [...] of the Amazonian forest and other tropical areas of the South and Central America. It has application in the treatment of several pathologies, including candidiasis. This work evaluates, clinical and laboratorial, the action of the Uncaria tomentosa gel in the oral cavity candidiasis patients. Twenty patients which presented clinical and laboratorial signs of Candida infection were selected. They were divided in 2 groups. The test-group (Uncaria tomentosa/IMUNO-MAX Gel), with 10 patients, was told to use the Uncaria tomentosa gel, on the oral cavity injuries, 3 times a day for a period of 14 days. The control-group (Miconazol/DAKTARIN Gel) used the prescribed medication in the same way of the test-group. After the treatment period, the patients returned for a new clinical and laboratorial evaluation. The Uncaria tomentosa showed to be a promising phytotherapeutical medication in dentistry, in the field of the anti-fungi treatment, presenting as advantage on the Miconazol not causing adverse reactions in the patients, once 40% of the control-group patients showed undesirable reactions.

Treatment and prophylaxis of invasive candidiasis with anidulafungin, caspofungin and micafungin and its impact on use and costs - review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Invasive fungal infections are on the rise. Echinocandins are a relatively new class of antifungal drugs that act by inhibition of a key enzyme necessary for integrity of the fungal cell wall. Currently there are three available agents: caspofungin, micafungin and anidulafungin. While the individual echinocandin antifungals have a different spectrum of licensed indications, basically all of them are available for the treatment of candidemia and invasive candidiasis. Antifungal treatment modalities basically include in therapy for suspected or proven infection and prophylaxis. All three drugs are comparatively expensive. Therefore a systematic review of the literature was performed to investigate the following aspects: • General aspects of cost-effectiveness in the treatment of invasive fungal infections • Cost-effectiveness of the treatment with the above-mentioned antifungals • Cost-effectiveness in two settings: therapy and prophylaxis Early initiation of antifungal therapy, adjustment after availability of microbiological results, duration of therapy, success and occurrence of severe complications (e.g renal failure are the most important cost drivers in antifungal therapy. Considering the specific antifungals, for caspofungin the best evidence for cost-effectiveness is found in treatment of invasive candidiasis and in empiric therapy of suspected infections. Favourable economic data are available for micafungin as a cost-effective alternative to LAmB for prophylaxis in patients with hematopoietic stem cell transplantation (HSCT. For anidulafungin, cost-effectiveness was demostrated in a pharmacoeconomic model. Net savings - yet not significant - were observed in a retrospective chart review of 234 patients. Generally, however, most analyses are still based on pharmacoeconomic modelling rather than direct analysis of trial data or real-life clinical populations. As an overall conclusion, using caspofungin, micafungin, or anidulafungin is not more expensive than using other established therapies. Micafungin has proven to be cost-effective in prophylaxis if the local fungal epidemiology indicates a high level of resistance to fluconazole. Switch strategies involving early initiation of broadly active therapy with switch to cheaper alternatives according to microbiology results and clinical status and early initiation of an appropriate therapy have been proven to be cost-efficient independent of the antifungal agent.

Use of antifungal saponin SC-2 of Solanum chrysotrichum for the treatment of vulvovaginal candidiasis: in vitro studies and clinical experiences.  

Science.gov (United States)

Saponin SC-2 from Solanum chrysotrichum showed antifungal activity, demonstrated in vitro, which inhibited the growth of dermatophytes, and in vivo, to be effective in the treatment against tinea pedis and pityriasis capitis. Fungistatic and fungicidal activity of saponin SC-2 on Candida albicans and other Candida species, fluconazole and ketoconazole resistaent strains was demostrated. SC-2-associated ultrastructural alterations in several Candida species were observed. An exploratory clinical, randomized, double-blind, and controlled ketoconazole study of ketoconazole was conducted with the aim of assessing the effectiveness and tolerability of an herbal medicinal product containing SC-2, on women with Vulvovaginal candidiasis (VVC). The results exhibited a percentage of therapeutic clinical effectiveness similar to that of ketoconazole (X(2), p ?0.30), but obtained a smaller percentage of mycological effectiveness, and 100% tolerability. In conclusion, saponin SC-2 possesses fungicidale and fungistatic activity on Candida albicans and other multi resistant Candida species, causes morphological changes and fungal death, and it is an alternative therapy for the treatment of VVC.

Determinants of Symptomatic Vulvovaginal Candidiasis among Human Immunodeficiency Virus Type 1 Infected Women in Rural KwaZulu-Natal, South Africa  

Science.gov (United States)

Introduction. We sought to determine the association between HIV-induced immunosuppression, virologic correlates, and vulvovaginal candidiasis (VVC). Methods. This is a retrospective cohort study, where HIV infected and uninfected women were studied with VVC being the primary outcome. Ninety-seven HIV-infected and 101 HIV-uninfected women were enrolled between June and December 2011. Cases of VVC were confirmed. HIV RNA load was determined by RT-PCR and CD4 counts were obtained from medical records. Results. Fifty-two of 97 (53.6%) HIV-infected and 38/101 (37.6%) HIV-uninfected women were diagnosed with VVC (P = 0.032). The relative risk for VVC amongst HIV-infected patients was 1.53 (95% CI: 1.04–2 P = 0.024). Cases of VVC increased at CD4+ T cell count below 200?cells/mm3 (P < 0.0001) and plasma HIV RNA load above 10 000?copies/mL (P < 0.0001). VVC was associated with increased genital shedding of HIV (P = 0.002), and there was a linear correlation between plasma HIV load and genital HIV shedding (r = 0.540; R2 = 0.292; P < 0.0001). Women on HAART were 4-fold less likely (P = 0.029) to develop VVC. Conclusion. CD4 counts below 200?cells/mm3 and plasma HIV loads ?10 000?copies/mL were significantly associated with VVC.

Comparison of four molecular typing methods for evaluating genetic diversity among Candida albicans isolates from human immunodeficiency virus-positive patients with oral candidiasis.  

Science.gov (United States)

Candida albicans strain delineation by karyotyping. NotI restriction pattern analysis, hybridization with specific probe 27A, and PCR fingerprinting with the phage M13 core sequence were performed with 30 isolates from the oral cavities of 30 human immunodeficiency virus (HIV)-infected patients and 8 reference strains. Within the panel of clinical isolates, 20 were geographically related, although 10 isolates were susceptible to fluconazole and 10 isolates were resistant to fluconazole. The remaining isolates used in this study were fluconazole resistant and geographically unrelated. A composite DNA type was defined for each of the strains as the combination of types obtained by the four molecular methods. By this procedure, a great diversity of DNA types was found among isolates from the oropharynges of HIV-infected individuals with oral candidiasis. This diversity was not reduced when isolates were evaluated on the basis of whether they came from the same geographical locale and whether they were fluconazole resistant. These data refute the idea of a clonal origin for fluconazole-resistant strains among HIV-positive patients. Karyotyping was the least discriminatory method, yielding 19 DNA types among the 38 strains analyzed. Conversely, hybridization with the 27A probe showed a unique DNA pattern for each of the strains examined in this study. Our results demonstrate that at least two different molecular methods are needed for Candida albicans typing and that there is a great deal of strain variation within the species, irrespective of place of origin or antifungal resistance patterns.

Single-dose miconazole nitrate vaginal ovule in the treatment of vulvovaginal candidiasis: two single-blind, controlled studies versus miconazole nitrate 100 mg cream for 7 days.  

Science.gov (United States)

To determine the efficacy and safety of a single-dose (1200 mg) soft gel insert (vaginal ovule) with miconazole nitrate (2%) topical cream compared with Monistat 7 (miconazole nitrate 2%) Vaginal Cream (Advanced Care Products, North Brunswick NJ) in treating vulvovaginal candidiasis (VVC), two randomized, single-blind, multicenter, controlled, comparative phase III studies were performed. Five hundred fifty-eight patients received either a single-dose miconazole nitrate (1200 mg) ovule or seven consecutive doses of Monistat 7. Ovule arm patients also received miconazole nitrate 2% cream for symptom relief, as needed, up to twice daily. The primary end point was a therapeutic cure. Also evaluated were time to complete symptom relief, safety, and patient preference. The ovule had overall cure rates of 71.7% (71 of 99 patients) and 61.5% (64 of 104 patients). Monistat 7 had overall cure rates of 70.1% (68 of 97 patients) and 61.1% (55 of 90 patients). A significantly greater proportion of patients experienced complete symptom relief by day 3 with the ovule (p = 0.008 and p = 0.025), and time to complete relief was significantly faster (median 4 versus 5 days and 3 versus 4 days). Overall safety results were consistent between groups in both studies. Miconazole nitrate vaginal ovule is as safe and efficacious in curing VVC as Monistat 7 while providing complete symptom relief significantly faster. Patients preferred the ovule to prior therapy.

Epidemiology and Outcomes of Invasive Candidiasis Due to Non-albicans Species of Candida in 2,496 Patients: Data from the Prospective Antifungal Therapy (PATH) Registry 2004-2008  

Science.gov (United States)

This analysis describes the epidemiology and outcomes of invasive candidiasis caused by non-albicans species of Candida in patients enrolled in the Prospective Antifungal Therapy Alliance (PATH Alliance) registry from 2004 to 2008. A total of 2,496 patients with non-albicans species of Candida isolates were identified. The identified species were C. glabrata (46.4%), C. parapsilosis (24.7%), C. tropicalis (13.9%), C. krusei (5.5%), C. lusitaniae (1.6%), C. dubliniensis (1.5%) and C. guilliermondii (0.4%); 111 infections involved two or more species of Candida (4.4%). Non-albicans species accounted for more than 50% of all cases of invasive candidiasis in 15 of the 24 sites (62.5%) that contributed more than one case to the survey. Among solid organ transplant recipients, patients with non-transplant surgery, and patients with solid tumors, the most prevalent non-albicans species was C. glabrata at 63.7%, 48.0%, and 53.8%, respectively. In 1,883 patients receiving antifungal therapy on day 3, fluconazole (30.5%) and echinocandins (47.5%) were the most frequently administered monotherapies. Among the 15 reported species, 90-day survival was highest for patients infected with either C. parapsilosis (70.7%) or C. lusitaniae (74.5%) and lowest for patients infected with an unknown species (46.7%) or two or more species (53.2%). In conclusion, this study expands the current knowledge of the epidemiology and outcomes of invasive candidiasis caused by non-albicans species of Candida in North America. The variability in species distribution in these centers underscores the importance of local epidemiology in guiding the selection of antifungal therapy.

Anidulafungin versus caspofungin in a mouse model of candidiasis caused by anidulafungin-susceptible Candida parapsilosis isolates with different degrees of caspofungin susceptibility.  

Science.gov (United States)

Candida parapsilosis isolates occasionally display resistance in vitro to echinocandins and cause breakthrough infections to echinocandins. The degree of the in vivo cross-resistance among echinocandins and the fitness loss associated with caspofungin (CAS) resistance of C. parapsilosis are not well studied. We compared the activities of CAS and anidulafungin (ANF), each given at 2 dosing schedules (high dose or low dose) in a nonneutropenic mouse model of invasive candidiasis (IC) caused by ANF-susceptible isolates of C. parapsilosis with different degrees of susceptibility to CAS (CAS resistant [CAS-R], MIC, >16 mg/liter; CAS intermediate [CAS-I], MIC, 4 mg/liter; and CAS susceptible [CAS-S], MIC, 2 mg/liter). We analyzed tissue fungal burden, histopathology, and weight loss patterns. Increasing CAS resistance was associated with reduced virulence of C. parapsilosis isolates (mortality rates for CAS-S versus CAS-I versus CAS-R, 100% versus 11.1% versus 0%, respectively; P < 0.001). High doses of either echinocandin were active against infection with the CAS-I isolate when assessed by fungal burden reduction and weight gain. In contrast to CAS-S and CAS-I isolates, there was no reduction in fungal burden in mice infected with the CAS-R isolate following treatment with either echinocandin, each given at a high or low dose. Nevertheless, mice infected with the CAS-R isolate had reduced disease severity following echinocandin treatment, suggesting that echinocandins have activity in vivo, even against echinocandin-resistant strains. A complex interplay of residual echinocandin activity, decreased virulence, and/or fitness of isolates with altered cell wall and possible immunomodulatory effects can be encountered in vivo during infection with CAS-resistant C. parapsilosis isolates.

New and recurrent gain-of-function STAT1 mutations in patients with chronic mucocutaneous candidiasis from Eastern and Central Europe  

Science.gov (United States)

Background Chronic mucocutaneous candidiasis disease (CMCD) may result from various inborn errors of interleukin (IL)-17-mediated immunity. Twelve of the 13 causal mutations described to date affect the coiled-coil domain (CCD) of STAT1. Several mutations, including R274W in particular, are recurrent, but the underlying mechanism is unclear. Objective To investigate and describe nine patients with CMCD in Eastern and Central Europe, to assess the biochemical impact of STAT1 mutations, to determine cytokines in supernatants of Candida-exposed blood cells, to determine IL-17-producing T cell subsets and to determine STAT1 haplotypes in a family with the c.820C>T (R274W) mutation. Results The novel c.537C>A (N179K) STAT1 mutation was gain-of-function (GOF) for ?-activated factor (GAF)-dependent cellular responses. In a Russian patient, the cause of CMCD was the newly identified c.854 A>G (Q285R) STAT1 mutation, which was also GOF for GAF-dependent responses. The c.1154C>T (T385M) mutation affecting the DNA-binding domain (DBD) resulted in a gain of STAT1 phosphorylation in a Ukrainian patient. Impaired Candida-induced IL-17A and IL-22 secretion by leucocytes and lower levels of intracellular IL-17 and IL-22 production by T cells were found in several patients. Haplotype studies indicated that the c.820C>T (R274W) mutation was recurrent due to a hotspot rather than a founder effect. Severe clinical phenotypes, including intracranial aneurysm, are presented. Conclusions The c.537C>A and c.854A>G mutations affecting the CCD and the c.1154C>T mutation affecting the DBD of STAT1 are GOF. The c.820C>T mutation of STAT1 in patients with CMCD is recurrent due to a hotspot. Patients carrying GOF mutations of STAT1 may develop multiple intracranial aneurysms by hitherto unknown mechanisms.

Anidulafungin compared with fluconazole for treatment of candidemia and other forms of invasive candidiasis caused by Candida albicans: a multivariate analysis of factors associated with improved outcome  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Candida albicans is the most common cause of candidemia and other forms of invasive candidiasis. Systemic infections due to C. albicans exhibit good susceptibility to fluconazole and echinocandins. However, the echinocandin anidulafungin was recently demonstrated to be more effective than fluconazole for systemic Candida infections in a randomized, double-blind trial among 245 patients. In that trial, most infections were caused by C. albicans, and all respective isolates were susceptible to randomized study drug. We sought to better understand the factors associated with the enhanced efficacy of anidulafungin and hypothesized that intrinsic properties of the antifungal agents contributed to the treatment differences. Methods Global responses at end of intravenous study treatment in patients with C. albicans infection were compared post-hoc. Multivariate logistic regression analyses were performed to predict response and to adjust for differences in independent baseline characteristics. Analyses focused on time to negative blood cultures, persistent infection at end of intravenous study treatment, and 6-week survival. Results In total, 135 patients with C. albicans infections were identified. Among these, baseline APACHE II scores were similar between treatment arms. In these patients, global response was significantly better for anidulafungin than fluconazole (81.1% vs 62.3%; 95% confidence interval [CI] for difference, 3.7-33.9. After adjusting for baseline characteristics, the odds ratio for global response was 2.36 (95% CI, 1.06-5.25. Study treatment and APACHE II score were significant predictors of outcome. The most predictive logistic regression model found that the odds ratio for study treatment was 2.60 (95% CI, 1.14-5.91 in favor of anidulafungin, and the odds ratio for APACHE II score was 0.935 (95% CI, 0.885-0.987, with poorer responses associated with higher baseline APACHE II scores. Anidulafungin was associated with significantly faster clearance of blood cultures (log-rank p p Conclusions In patients with C. albicans infection, anidulafungin was more effective than fluconazole, with more rapid clearance of positive blood cultures. This suggests that the fungicidal activity of echinocandins may have important clinical implications. Trial registration ClinicalTrials.gov: NCT00058682

Pulmonary candidiasis presenting as mycetoma.  

Science.gov (United States)

Candida is a saprophytic yeast that is frequently recovered from the respiratory tract. Most mycetoma lesions are due to Aspergillus species growing inside an existing cavity. The saprophytic nature of the Candida species in the human respiratory tract obscures diagnosis of Candida pulmonary infections. Only a few cases of mycetoma due to Can-dida have been reported. We report a case of mycetoma caused by Candida albicans in a diabetic immunocompromised tuberculous patient. Diagnosis was confirmed by biopsy and certain points strongly favoured the diagnosis. The patient was immunocompromised due to uncontrolled diabetes mellitus. Candida albicans was grown from bronchial and repeatedly from sputum samples and Candida antigen was positive from blood in high titre. There was a good clinical as well as radiological response to antifungal therapy and Candida antigen became negative. We emphasize that in the immunosuppressed host, a mycetoma-like lesion may be caused by Candida pulmonary infection. PMID:21264087

Experimental candidiasis after thermal injury.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The ability of Candida albicans to infect thermally injured mice was studied. Female mice were either left unburned or given a 20% total body surface area 2-s or 7-s scald burn. The wound or skin surface was then inoculated with a human burn wound isolate of C. albicans. At 4 h postburn, approximately 10(2) to 10(3) CFU/g of tissue could be recovered from the skin of burned and unburned animals. Unburned mice cleared the organisms from the skin by 72 h, whereas in 7-s-burned animals, the cand...

A razão de cura do tratamento com fluconazol também foi avaliada. TIPO DE ESTUDO E LOCAL: Estudo transversal realizado no sistema público de saúde de Maringá, Paraná, Brazil. MÉTODO: O estudo envolveu 717 mulheres de 17-74 anos de idade e, destas, 48 (6,7%) tinham DM 2 (média de 53,7 anos), independentemente de sinais e sintomas de CVV. As leveduras foram isoladas e identificadas por métodos fenotípicos clássicos. RESULTADOS: No grupo de não diabéticas (controle), leveduras vaginais totais foram isoladas em 79 (11,8%) mulheres, e no grupo de diabéticas, em 9 (18,8%) (P = 0,000). O grupo de diabéticas mostrou mais mulheres sintomáticas (CVV + CVVR = 66,66%) do que colonizadas (33.33%), e significativamente mais colonização, CVV e CVVR, que as controle. A razão média de cura com fluconazol foi de 75.0% no grupo diabéticas e 86.7% no controle (P = 0.51). CONCLUSÃO: Nós encontramos que DM 2 em mulheres brasileiras associou-se com colonização vaginal por leveduras, CVV e CVVR, razão similar de isolamento de C. albicans e espécies não albicans. Boa taxa de cura foi obtida com fluconazol em ambos os grupos. Abstract in english CONTEXT AND OBJECTIVE: Vulvovaginal candidiasis (VVC) is caused by abnormal growth of yeast-like fungi on the female genital tract mucosa. Patients with diabetes mellitus (DM) are more susceptible to fungal infections, including those caused by species of Candida. The present study investigated th [...] e frequency of total isolation of vaginal Candida spp., and its different clinical profiles - colonization, VVC and recurrent VVC (RVVC) - in women with DM type 2, compared with non-diabetic women. The cure rate using fluconazole treatment was also evaluated. DESIGN AND SETTING: Cross-sectional study conducted in the public healthcare system of Maringá, Paraná, Brazil. METHODS: The study involved 717 women aged 17-74 years, of whom 48 (6.7%) had DM type 2 (mean age: 53.7 years), regardless of signs and symptoms of VVC. The yeasts were isolated and identified using classical phenotypic methods. RESULTS: In the non-diabetic group (controls), total vaginal yeast isolation occurred in 79 (11.8%) women, and in the diabetic group in 9 (18.8%) (P = 0.000). The diabetic group showed more symptomatic (VVC + RVVC = 66.66%) than colonized (33.33%) women, and showed significantly more colonization, VVC and RVVC than seen among the controls. The mean cure rate using fluconazole was 75.0% in the diabetic group and 86.7% in the control group (P = 0.51). CONCLUSION: We found that DM type 2 in Brazilian women was associated with yeast colonization, VVC and RVVC, and similar isolation rates for C. albicans and non-albicans species. Good cure rates were obtained using fluconazole in both groups.

Glossite rombóide mediana associada a candidíase esofagiana: uma possível relação etiológica com a Candida albicans Median rhomboid glossitis associated with esophagic candidiasis: a possible etiologic relation with Candida albicans  

Directory of Open Access Journals (Sweden)

Full Text Available A glossite rombóide mediana é doença inflamatória que ocorre na superfície da língua. Apresenta-se como placa avermelhada ou vermelho-esbranquiçada no dorso da língua, na localização mediana. A etiologia é desconhecida. Acredita-se que possa haver relação com a má formação dos arcos branquiais durante a embriogênese. Fatores infecciosos relacionados à Candida albicans também são aventados. Os autores apresentam o caso clínico de uma paciente de 60 anos, com glossite rombóide mediana associada a esofagite candidiásica, ambas responsivas ao tratamento com itraconazol e fluconazol oral. Discute-se se a cândida não seria um dos fatores implicados na etiologia da doença lingual.Median rhomboid glossitis is an inflammatory disease involving the surface of the tongue. It develops clinically as an erythematous or white-erythematous area on the dorsal median surface of the tongue. Etiologic factors are unknown. One of the possible etiologic theories suggests a relation between median rhomboid glossitis and malformation of bronchial arches during embriogenesis. Candida albicans as an infectious etiologic factor has also been suggested. The study presents the case of a 60-year-old patient with median rhomboid glossitis associated with esophagic candidiasis. Both pathologies responded well to therapy with oral itraconazole and fluconazole. The authors argue in favor of the possibility of an etiologic relation between Candida albicans and median rhomboid glossitis .

Vaginal epithelial cell-derived S100 alarmins induced by Candida albicans via pattern recognition receptor interactions are sufficient but not necessary for the acute neutrophil response during experimental vaginal candidiasis.  

Science.gov (United States)

Vulvovaginal candidiasis (VVC), caused by Candida albicans, affects women worldwide. Animal and clinical studies suggest that the immunopathogenic inflammatory condition of VVC is initiated by S100 alarmins in response to C. albicans, which stimulate polymorphonuclear neutrophil (PMN) migration to the vagina. The purpose of this study was to extend previous in vitro data and determine the requirement for the alarmin S100A8 in the PMN response and to evaluate pattern recognition receptors (PRRs) that initiate the response. For the former, PMN migration was evaluated in vitro or in vivo in the presence or absence of S100 alarmins initiated by several approaches. For the latter, vaginal epithelial cells were evaluated for PRR expression and C. albicans-induced S100A8 and S100A9 mRNAs, followed by evaluation of the PMN response in inoculated PRR-deficient mice. Results revealed that, consistent with previously reported in vitro data, eukaryote-derived S100A8, but not prokaryote-derived recombinant S100A8, induced significant PMN chemotaxis in vivo. Conversely, a lack of biologically active S100A8 alarmin, achieved by antibody neutralization or by using S100A9(-/-) mice, had no effect on the PMN response in vivo. In PRR analyses, whereas Toll-like receptor 4 (TLR4)- and SIGNR1-deficient vaginal epithelial cells showed a dramatic reduction in C. albicans-induced S100A8/S100A9 mRNAs in vitro, inoculated mice deficient in these PRRs showed PMN migration similar to that in wild-type controls. These results suggest that S100A8 alarmin is sufficient, but not necessary, to induce PMN migration during VVC and that the vaginal PMN response to C. albicans involves PRRs in addition to SIGNR1 and TLR4, or other induction pathways.

The hormonal status of rats affected vaginal infection with Candida albicans. Four hours after infection viable counts were higher and germ tubes were longer in those animals in estrous than in other animals. However, the infection was not maintained with the change in epithelial cell type which occurred as part of the estrous cycle. Estrogen dosing following ovariectomy predisposed toward infection, while progesterone dosing did not. In rats injected with progesterone, germ tube clumping was...

Un objetivo secundario fue describir la evaluación y el consejo proporcionado a los pacientes cuando solicitaban esta medicación. Métodos: Se realizó un ensayo controlado aleatorizado donde dos pacientes simulados condujeron visitas a 100 farmacias comunitarias aleatoriamente seleccionadas en una región metropolitana. Se comparó una solicitud de un producto con fluconazol (antifúngico oral que tiene guía) con una solicitud de un producto con clotrimazol (un antifúngico tópico sin guía). Los mismos datos de los pacientes fueron usados en ambas solicitudes. Las medidas de resultados en las visitas fueron la adecuación del suministro y la remisión al médico. Resultados: Un total de un 16% (n=16) de las visitas produjeron resultados apropiados; 10% (n=5) de fluconazol comparadas con el 22% (n=11) de clotrimazol (chi-square= 2,68, p=0,10). Hubo una diferencia significativa en el tipo de evaluación realizada por el personal de la farmacia entre las visitas del fluconazol y del clotrimazol.

MÉTODOS: foi desenvolvido estudo prospectivo de julho de 2001 a julho de 2003 com uma amostra de mulheres residentes na Grande São Paulo. Foram avaliadas 179 pacientes com suspeita clínica de vaginite fúngica, com idade entre 18 e 65 anos. Os critérios para exclusão foram: gravidez, comprometimento imunológico intrínseco e extrínseco, incluindo AIDS, diabetes, imunossupressão, pacientes em terapia com corticosteróides, antibióticos ou hormônios, em pós-menopausa, em uso de dispositivo intra-uterino e duchas vaginais ou espermicidas. Amostras de secreções vaginais ou da glande dos parceiros sexuais de pacientes com vaginite de repetição foram coletadas para microscopia e cultura de fungos. Colônias fúngicas isoladas em CHROMagar Candida foram identificadas por provas clássicas. O teste exato de Fisher foi usado para correlacionar o quadro clínico com as leveduras isoladas das pacientes. RESULTADOS: os sinais e sintomas clínicos mais relevantes na candidíase vulvovaginal foram prurido e corrimento, seguidos por eritema e edema, estatisticamente independente do agente etiológico. Leveduras foram diagnosticadas por microscopia direta em 77 pacientes com vulvovaginites, sendo obtidos 40 cultivos de Candida spp. Candida albicans (70%, C. glabrata (20%, C. tropicalis (7,5% e C. guilliermondii (2,5% foram identificadas. As leveduras prevalentes nos parceiros foram C. albicans e C. glabrata. As mesmas espécies foram detectadas nas companheiras e parceiros em 87% dos casos. CONCLUSÕES: as vulvovaginites fúngicas foram mais freqüentes em mulheres entre 18 e 34 anos de idade. Não foi observada correlação entre as espécies de leveduras detectadas e a sintomatologia clínica. Os parceiros sexuais podem ser importantes reservatórios de Candida spp e estar relacionados à manutenção da candidíase vulvovaginal.PURPOSE: to relate yeasts identified by laboratory tests to clinical signs and symptoms in patients with vulvovaginal candidiasis, and to investigate the importance of the sexual partners in the recurrence of the infection. METHODS: from July 2001 to July 2003, a sample of 179 patients aged from 18 to 65 years old, with clinical suspicion of fungal vaginitis were analyzed in a prospective study in Great São Paulo. Exclusion criteria included: pregnancy, impaired intrinsic or extrinsic immune response (including Aids, diabetes or immunosuppression; patients undergoing corticosteroid, antibiotic or hormone therapy, in post menopause, with intrauterine device (IUD or making use of vaginal douches or spemicides. Samples of vaginal and penis secretions from partners of patients with relapse of vaginitis episodes were collected for microscopy and fungal culture. Fungal colonies isolated in CHROMagar Candida were identified by classical methods. Fisher's exact t-test was used to correlate the clinical picture with the yeasts isolated from patients. RESULTS: the most relevant clinical signs and symptoms were pruritus and vaginal discharge followed by erythema and edema, statistically independent from the etiological agent. Direct microscopy revealed yeasts in 77 patients with vulvovaginitis, and 40 Candida spp cultures were obtained. Candida albicans (70%, C. glabrata (20%, C. tropicalis (7,5% and C. guilliermondii (2,5% were identified. The yeasts prevalent in partners were C. albicans and C. glabrata. The same species were detected in female and male sex partners in 87% of the cases. CONCLUSIONS: fungal vulvovaginitis was more frequent in women between 18 and 34 years old. No correlation was observed between the species of yeast detected and clinical symptomatology. Sexual partners are important Candida spp reservoirs and may be related to the maintenance of the vulvovaginal candidiasis.

Neonatal systemic candidiasis in a tertiary care centre  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to identify infections causing Candida spp. and to examine their susceptibility to antifungal drugs. The study examined 30 isolates of Candida spp. grown from blood culture samples of neonates. Clinical histories revealed that all 30 infants had received systemic broad-spectrum antibiotic therapy, 27/30 were low birth weight, 21/30 suffered from respiratory distress syndrome and 23/30 were preterm. The three species of Candida isolated were Candida albicans (16/30, 53.3%, C. tropicalis (7/30,23.3%, and C. krusei (7/30, 23.3%. Antifungal susceptibility tests against fluconazole and amphotericin B were done based on the NCCLS guidelines for antifungal susceptibility testing. The fluconazole resistance pattern was as follows: 1/16 (6.25% strain of C. albicans was susceptible, 12/16 (75% strains were dose dependent susceptibles, and 3/16 (18.75% were resistant to fluconazole. Among Candida tropicalis, 2/7(29% strains were susceptible, 4/7 (55.5% dose dependent susceptible and 1/7 (14.5% were resistant. All strains of C. krusei were resistant to fluconazole. There was no resistance to amphotericin B.

Prevalence and Management of Non-albicans Vaginal Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Abstract Objectives It is thought that widespread use of “over-the-counter” azoles may increase the incidence of resistant Candida species such as C glabrata. Infections with species other than C. albicans frequently do not respond to standard azole treatments. Intravaginal nystatin is an option but is no longer available in the UK. In this paper, we review the prevalence of non-albicans candida over the past five years, and assess the efficacy of amphotericin and flucytosin...

Treatment of invasive candidiasis in the elderly: a review  

Directory of Open Access Journals (Sweden)

Full Text Available Aikaterini Flevari,1 Maria Theodorakopoulou,1 Aristea Velegraki,2 Apostolos Armaganidis,1 George Dimopoulos1 1Department of Critical Care, University Hospital Attikon, Medical School, 2Mycology Laboratory, Department of Microbiology, Medical School, University of Athens, Athens, Greece Abstract: Fungi are major causes of infections among immunocompromised or hospitalized patients with serious underlying diseases and comorbidities. Candida species remain the most important cause of opportunistic infections worldwide, affecting predominantly patients over 65 years old, while they are considered to be the fourth most common cause of nosocomial bloodstream infections. The rapidly growing elderly population has specific physiological characteristics, which makes it susceptible to colonization and subsequent infection due to Candida species. Comorbidities and multidrug use should be taken into account any time the therapeutic regimen is under consideration. Different classes of antifungal drugs are available for the treatment of invasive fungal infections but echinocandins, apart from their activity against resistant strains (Candida glabrata and Candida krusei, seem to be safe, with limited adverse events and minimal drug–drug interactions in comparison to the other regimens. Therefore, these agents are strongly recommended when dealing with elderly patients suffering from an invasive form of Candida infection.

In Vivo Analysis of Secreted Aspartyl Proteinase Expression in Human Oral Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Secreted aspartyl proteinases are putative virulence factors in Candida infections. Candida albicans possesses at least nine members of a SAP gene family, all of which have been sequenced. Although the expression of the SAP genes has been extensively characterized under laboratory growth conditions, no studies have analyzed in detail the in vivo expression of these proteinases in human oral colonization and infection. We have developed a reliable and sensitive procedure to detect C. albicans ...

Eucalyptus globulus (Eucalyptus) Treatment of Candidiasis in Normal and Diabetic Rats  

Science.gov (United States)

Background: The leaves of Eucalyptus globulus (eucalyptus) are used for treatment of diabetes mellitus in traditional medicine. The aim of this study was to evaluate the effects of eucalyptus in treatment of established systemic infection with Candida albicans in normal and streptozotocin-induced diabetic rats. Methods: Sixty normoglycemic male Wistar rats, weighing 200-250 g, were selected and randomly divided into six groups (n= 10): normal control, control + C. albicans, control + eucalyptus + C. albicans, diabetic control, diabetic + C. albicans, diabetic + eucalyptus + C. albicans. Diabetes was induced after a single intraperitoneal injection of streptozotocin (60 mg/kg body weight) and eucalyptus was added to the diet (62.5 g/kg) and drinking water (2.5 g/L) of treated animals for 4 weeks. The concerned groups were inoculated with C. albicans 15 days after diabetes induction. At the end of one month experiment, fasted rats were killed by cervical decapitation. Blood was collected from neck vein for estimation of glucose. C. albicans concentrations were estimated in liver and kidneys using serial dilution culture of tissue homogenates. Results: Eucalyptus administration significantly improved the hyperglycemia, polydipsia, polyphagia, and it also compensated weight loss of diabetic rats (P<0.05). Moreover, eucalyptus caused a significant reduction in C. albicans concentration in liver and kidney homogenates (P<0.01). Conclusion: The results revealed that eucalyptus improves Candidia infection in normal and diabetic rats that in some ways validates the traditional use of this plant in treatment of diabetic patients.

Vaginal Epithelial Cell Anti-Candida albicans Activity Is Associated with Protection against Symptomatic Vaginal Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Vaginal epithelial cell (VEC) anti-Candida albicans activity, despite being measured in vitro, is considered an innate host defense mechanism. This was supported further by the fact that women protected from symptomatic infection following a live intravaginal Candida challenge had increased VEC anti-Candida activity compared to those who acquired a symptomatic infection.

Clinical pharmacodynamic index identification for micafungin in esophageal candidiasis: dosing strategy optimization.  

Science.gov (United States)

Echinocandins exhibit concentration-dependent effects on Candida species, and preclinical studies support the administration of large, infrequent doses. The current report examines the pharmacokinetics/pharmacodynamics of two multicenter, randomized trials of micafungin dosing regimens that differed in both dose level and dosing interval. Analysis demonstrates the clinical relevance of the dose level and area under the concentration-time curve (AUC). Better, although not statistically significant (P = 0.056), outcomes were seen with higher maximum concentrations of drug in serum (Cmax) and large, infrequent doses. The results support further clinical investigation of novel micafungin dosing regimens with large doses but less than daily administration. (These studies have been registered at ClinicalTrials.gov under registration no. NCT00666185 and NCT00665639.). PMID:23959319

Relationship between clinical factors and severity of esophageal candidiasis according to Kodsi's classification.  

Science.gov (United States)

Severe Candida esophagitis (CE) may lead to development of strictures, hemorrhage, esophagotracheal fistula, and a consequent decrease in quality of life. Although the severity of CE has been classified based on macroscopic findings on endoscopy, the clinical significance remains unknown. The aim of the study was to elucidate the predictive clinical factors for endoscopic severity of CE. Patients who underwent upper endoscopy and answered questionnaires were prospectively enrolled. Smoking, alcohol, human immunodeficiency virus (HIV) infection, diabetes mellitus, chronic renal failure, liver cirrhosis, systemic steroids use, proton pump inhibitor use, H2 blocker use, and gastrointestinal (GI) symptoms were assessed on the same day of endoscopy. GI symptoms including epigastric pain, heartburn, reflux, hunger cramps, nausea, dysphagia, and odynophagia were assessed on a 7-point Likert scale. Endoscopic severity was classified as mild (Kodsi's grade I/II) or severe (grade III/IV). Of 1855 patients, 71 (3.8%) were diagnosed with CE (mild, n?=?48; severe, n?=?23). In the CE patients, 50.0% (24/48) in the mild group and 23.1% (6/23) in the severe group did not have any GI symptoms. In HIV-infected patients (n?=?17), a significant correlation was found between endoscopic severity and declining CD4 cell count (Spearman's rho?=?-0.90; P?

Efficacy of continuous flucytosine infusion against Candida lusitaniae in experimental hematogenous murine candidiasis.

Candida lusitaniae may cause life-threatening infections in the immunocompromised host and may be resistant to amphotericin B. Flucytosine (5-FC) is very active against C. lusitaniae isolates in vitro, while the in vivo response of murine infection to 5-FC is not as good. To evaluate the hypothesis that this discrepancy may be primarily due to the short half-life of 5-FC in mice, we compared the same total dosage of 75 mg of 5-FC per kg of body weight per day given by bolus injections or infu...

The main objective is to formulate and evaluate in situ oral topical gels of clotrimazole based on the concept of pH triggered and ion activated systems. The system utilizes polymers that exhibit sol-to-gel phase transition due to change in specific physico-chemical parameters. A pH triggered system consisting of carbopol 934P (0.2-1.4% w/v and ion triggered system using gellan gum (0.1-0.75% w/v along with hydroxylpropylmethylcelluose E50LV was used to prolong the release of clotrimazole (0.1% w/v. Formulations were evaluated for gelling capacity, viscosity, gel strength, bioadhesive force, spreadability, microbiological studies and in vitro release. The use of carbopol as in situ gel forming system was substantiated by the property to transform into stiff gels when the pH was raised, whereas in gellan gum this transformation occurred in the presence of monovalent/divalent cations. Effect of calcium carbonate and other process parameters optimized and found that increase in calcium ions produced stronger gels. The drug content, clarity, and pH of the formulation were found to be satisfactory. The viscosity was found to be in the range 5 to 85 centipoise for the sol, whereas for the gels it was up to 16000 centipoise. The formulation showed pseudoplastic flow with thixotrophy. The maximum gel strength (using texture analyzer and bioadhesion was found to be up to 6.5 g and 4 g, respectively. The optimized formulations were able to release the drug up to 6 h. The formulation containing gellan gum showed better sustained release compared to carbopol based gels.

Cutaneous candidiasis caused by Candida glabrata in a HIV/AIDS patient.  

Science.gov (United States)

Cutaneous Candida infections may occur in patients with HIV/AIDS, cancer, receiving chemotherapy and solid organ transplantation. A 32-year-old woman was admitted to the department suffering from pruritic and erythematous plaque on left side of her face for the past two months. The patient was HIV positive, diagnosed five years previously, and had been on antiretroviral therapy (tenofovir/emtricitabine and lopinavir/ritonavir) for a year. She was not compliant with the medication. Elevated HIV RNA load and decreased CD4+ lymphocyte count were observed. Fungal elements were detected from the skin scraping sample taken from the facial plaque. Fluconazole-sensitive Candida glabrata was isolated from this sample. Topical clotrimazole ointment and systemic fluconazole 400 mg/day were used. After systemic fluconazole therapy was continued for two months, the plaque was cured. C. glabrata rarely causes cutaneous infection without involving the mucous membranes. Presentation of cutaneous fungal infections in HIV patients with decreased CD4+ T lymphocyte counts can be atypical and require extensive antifungal treatment. PMID:23970580

Characteristic and clinical relevance of Candida mannan test in the diagnosis of probable invasive candidiasis.  

Science.gov (United States)

The gold standard laboratory tests used to diagnose invasive Candida infection (ICI) are based on the in vitro culture of blood or samples from other sterile sites. However, these tests have limited sensitivity (Se) and are generally not diagnostic until late in the infectious process. The Serion Candida mannan kit was evaluated for the diagnosis of ICI at Grenoble University Hospital (France) between 2007 and 2011. The results were then compared with worldwide data published between 1997 and 2011. This retrospective study was based on follow-up from the investigation of 162 patients of whom 91 had proven ICI; 13 had Candida colonization index (CCI) scores ?0.42, positive mannan tests, with nonconcomitant infections; and 58 had no evidence of Candida infection. Candida albicans, C. glabrata, C. tropicalis, and C. parapsilosis were the etiologic agents in 104 patients. For patients with or without ICI, the 12-week mortality rates were 35/104 (33.7%) and 6/58 (10.3%), respectively. The mannan diagnostic specificity was 51% and Se was 77%. However, in the metaanalysis (n = 1,536), values were 86% and 62%, respectively. Positive mannan test results may appear early (median 6 days) in the development of candidemia and have moderate diagnostic value for ICI, with a negative predictive value of 83%. In patients at risk of ICI with negative candidemia, the combination of Candida mannan test data with a CCI score ?0.42 may improve the diagnosis of probable ICI. PMID:24934805

Role of tetracycline in pathogenesis of chronic candidiasis of rat tongues.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Forty female Sprague-Dawley rats were randomly divided into two groups. Group 1 animals received tetracycline solution (0.1% during week 1 and 0.01% thereafter) as drinking water, as in previous studies. Group 2 animals received double-distilled demineralized water. Animals in both groups were inoculated orally with an equal number of viable, mucosally pathogenic Candida albicans organisms. After 20 weeks, inspection of the tongues showed gross lesions in 16 of the 20 animals in group 1 and 1...

Severe systemic candidiasis following immunomodulation therapy in in vitro fertilisation-embryo transfer (IVF-ET).  

Science.gov (United States)

A 41-year-old nulliparous woman, with a medical history of unexplained infertility and multiple in vitro fertilisation (IVF) cycles with immunosuppressive therapy, was admitted to our tertiary obstetrics unit with sepsis at 18 weeks of pregnancy with dichorionic diamniotic twins. Candida glabrata was grown from her blood cultures, then subsequently from the liquor and placentae. She was treated with intravenous ambisome (amphotericin), but unfortunately, the infection resulted in the rupture of her membranes, preterm labour and the demise of her twins. She delivered both twins at 23 weeks, 3 days apart. The antifungal agent was changed to high-dose fluconazole after delivery for 2 weeks and she is now well. Women undergoing IVF-embryo transfer with immunomodulation therapy have a potential risk of developing candidal chorioamnionitis and sepsis. PMID:24686802

Bioadhesive vaginal tablets containing spray dried microspheres loaded with clotrimazole for treatment of vaginal Candidiasis.  

Science.gov (United States)

The aim of the present investigation was to prepare and evaluate novel bioadhesive vaginal tablets containing clotrimazole loaded microspheres in order to provide long-term therapeutic activity at the site of infection. Tablets were prepared by incorporating drug loaded microspheres and using bioadhesive polymers hydroxypropylmethylcellulose, sodium carboxymethylcellulose and Carbopol. Microspheres were prepared by the spray drying technique using Eudragit RS-100 and Eudragit RL-100. Microspheres were characterized by SEM, DSC, FTIR, particle size analysis and evaluated for percentage yield, drug loading, encapsulation efficiency and in vitro drug release. To achieve bioadhesion to the mucosal tissue, optimized microspheres were incorporated into bioadhesive tablets and were evaluated for in vitro drug release, in vitro and in vivo mucoadhesion. FTIR and DSC studies showed that no chemical interaction occurred between the drug and polymers. The sphericity factor indicated that the prepared microspheres were spherical. Formulation Mt6 indicated a controlled in vitro drug release and good bioadhesive strength. The in vivo images confirmed the bioadhesion and retention property of tablets up to 24 h. The results indicated that this drug delivery system can be explored for controlled intravaginal drug release. PMID:24152896

Quantification of arabinitol in serum by selected ion monitoring as a diagnostic technique in invasive candidiasis.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

D-Arabinitol was identified by mass spectrometry as a metabolite of Candida albicans and Candida tropicalis. For quantification, serum was deproteinized with acetone, the supernatant was evaporated to dryness, the silyl derivative was formed, and a portion was injected into a combined gas chromatograph-mass spectrometer system. Erythritol or 2-deoxy-galactitol was the internal standard. The protonated molecular ions, obtained in chemical ionization with isobutane, were monitored. For 39 norma...

Adjuvant effect of polysaccharide from fruits of Physalis alkekengi L. in DNA vaccine against systemic candidiasis.  

Science.gov (United States)

Adjuvant effect mediated by polysaccharide (PPSB) isolated from the fruits of Physalis alkekengi L. in DNA vaccine was evaluated in mice. Recombinant plasmid containing epitope C (LKVIRK) from heat shock protein 90 (HSP90) of Candida albicans (C. albican) was used as DNA vaccine (pD-HSP90C). The results indicated that PPSB significantly enhanced specific antibody titers IgG, IgG1, IgG2b, and concentration of IL-2 and IL-4 in sera of mice immunized with pD-HSP90C (p<0.05). More importantly, it was found that the mice immunized with pD-HSP90C/PPSB not only had fewer CFU (colony forming unites) in the kidneys than mice immunized with pD-HSP90C, but also a statistically significant higher survival rate over PBS-injected group (p<0.05) when the immunized mice were challenged with living C. albican cells. However, no statistically significant difference in survival rate was observed between pD-HSP90C-immunized group and PBS-injected group. Therefore, PPSB can be considered as a promising adjuvant eliciting both Th1 and Th2 responses to enhance the efficacy of DNA vaccines. PMID:24815404

Sonographic detection of intrarenal and intraarterial fungus balls in a preterm infant due to systemic candidiasis  

International Nuclear Information System (INIS)

Shortly after birth a preterm infant suffering from aspiration syndrome and subsequent Pseudomonas aeruginosa sepsis showed signs of renal insufficiency and mycotic infection: Yeast cells were identified in several urinalyses; there was also an increasing anti-Candida IgM antibody titer. At the same time sonographic examinations revealed an increasing echogenicity of the renal cortex and echogenic masses of variable size which did not cause acoustic shadows in both enlarged kidneys. A few days later, we found a right-sided hydronephrosis caused by an intraureteric prevesical mass of equal echogenicity. As we could observe sonographically, the aggressive antimycotic therapy was successful. Eleven weeks later there were signs of cardiac insufficiency. An angiographically demonstrated filling defect within the pulmonary artery showed the same sonographic findings as the previously found intrarenal masses. The baby underwent embolectomy and recovered. The thrombotic material contained yeast cells giving evidence of systemic Candidasis. Provided appropriate equipment is available, ultrasound today is an excellent non-invasive screening and followup method not only for echoencephalography, but also for more complicated neonatologic problems as seen here. The detailed observation of a changing echogenicity of the renal cortex and pelvis is important and often allows a decisive diagnostic clue before other radiological methods become conclusive.

Intravaginal and Intranasal Immunizations Are Equally Effective in Inducing Vaginal Antibodies and Conferring Protection against Vaginal Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Oophorectomized, estrogen-treated rats were immunized by the intravaginal or intranasal route with a mannoprotein extract (MP) or secreted aspartyl proteinases (Sap) of Candida albicans, with or without cholera toxin as a mucosal adjuvant. Both routes of immunization were equally effective in (i) inducing anti-MP and anti-Sap vaginal antibodies and (ii) conferring a high degree of protection against the vaginal infection by the fungus. These data suggest that appropriate fungal antigens and a...

Once-Weekly Micafungin Therapy Is as Effective as Daily Therapy for Disseminated Candidiasis in Mice with Persistent Neutropenia?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The effect of micafungin dose scheduling on the treatment of candidemia is unknown. Neutropenic mice with disseminated Candida glabrata infection were treated with single intraperitoneal micafungin doses of 0 to 100 mg/kg of body weight and sacrificed 7 days later. The maximal decline in kidney fungal burden was 5.8 log10 CFU/g. A 1-week pharmacokinetic-pharmacodynamic study revealed a micafungin serum half-life of 6.13 h. In mice treated with ?50 mg/kg, there was maximal fungal decline wit...

In vitro/in vivo performance of different complexes of itraconazole used in the treatment of vaginal candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A large majority of new chemical entities and many existing drug molecules exhibit poor aqueous solubility, which may limit their potential use in developing drug formulations, with optimum bioavailability. One of the approaches to improve the solubility of a poorly water soluble drug and eventually its bioavailability is complexation with agents like humic acid (HA), fulvic acid (FA), ?-cyclodextrin (?-CD), 2-hydroxypropyl-?-cyclodextrin (HP-?-CD) and caffeine (Caff).

Identification and study of non-Albicans Candida species isolated from clinical materials of patients with Candidiasis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Background: I Infections due to Candida spp. have increased dramatically in recent years through a rising number of predisposing factors and immunocompromised hosts. Although Candida albicans is the most prevalent and important causative agent of Candida infections, the importance of C. parapsilosis, C. tropicalis, C. krusei, C. glabrata, C. guilliermondii and C. kefyr have increased significantly as they tend to be more resistant to antifungal agents. Therefore, it is critical that infecting...

Scanning electron microscopy of epidermal adherence and cavitation in murine candidiasis: a role for Candida acid proteinase.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Adherence of blastoconidia to epidermal corneocytes is an early event in Candida colonization and infection of the skin. Pathogenic species adhere more avidly than nonpathogenic species, transform to hyphal growth, and invade the stratum corneum of the skin. Adherence was studied by scanning electron microscopy of experimental murine cutaneous Candida infections, using six species of Candida. Candida albicans and C. stellatoidea blastoconidia, applied to newborn mouse skin, adhered to the str...

Formulation, toxicity, and antifungal activity in vitro of liposome-encapsulated nystatin as therapeutic agent for systemic candidiasis.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Multilamellar vesicles containing nystatin (NYS) were compared with vesicles containing the free drug for toxicity to erythrocytes and for antifungal activity in vitro. Liposomal nystatin was as active as free NYS was against a wide variety of yeasts and fungi. The antifungal activity against Candida albicans was maintained with different liposome compositions and without sterols. Liposome encapsulation also protected the erythrocytes from the toxicity of free NYS.

The PAV trial: Does lactobacillus prevent post-antibiotic vulvovaginal candidiasis? Protocol of a randomised controlled trial [ISRCTN24141277  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Complementary and alternative medicines are used by many consumers, and increasingly are being incorporated into the general practitioner's armamentarium. Despite widespread usage, the evidence base for most complementary therapies is weak or non-existent. Post-antibiotic vulvovaginitis is a common problem in general practice, for which complementary therapies are often used. A recent study in Melbourne, Australia, found that 40% of women with a past history of vulvovaginitis had used probiotic Lactobacillus species to prevent or treat post-antibiotic vulvovaginitis. There is no evidence that this therapy is effective. This study aims to test whether oral or vaginal lactobacillus is effective in the prevention of post-antibiotic vulvovaginitis. Methods/design A randomised placebo-controlled blinded 2 × 2 factorial design is being used. General practitioners or pharmacists approach non-pregnant women, aged 18–50 years, who present with a non-genital infection requiring a short course of oral antibiotics, to participate in the study. Participants are randomised in a four group factorial design either to oral lactobacillus powder or placebo and either vaginal lactobacillus pessaries or placebo. These interventions are taken while on antibiotics and for four days afterwards or until symptoms of vaginitis develop. Women self collect a vaginal swab for culture of Candida species and complete a survey at baseline and again four days after completing their study medications. The sample size (a total of 496 – 124 in each factorial group is calculated to identify a reduction of half in post-antibiotic vulvovaginitis from 23%, while allowing for a 25% drop-out. An independent Data Monitoring Committee is supervising the trial. Analysis will be intention-to-treat, with two pre-specified main comparisons: (i oral lactobacillus versus placebo and (ii vaginal lactobacillus versus placebo.

Detection of fungal DNA in lysis-centrifugation blood culture for the diagnosis of invasive candidiasis in neonatal patients.  

Science.gov (United States)

We report data concerning the detection of fungal DNA directly from lysis-centrifugation blood culture to assess its value in the detection of fungaemia in 86 of the 347 patients admitted to the neonatal intensive-care unit between January 2009 and December 2010. The sensitivity and specificity of the PCR were 87.5% and 98.5%, respectively, with a positive predictive value of 93.3% and a negative predictive value of 97.1%. Detection of fungal DNA directly from blood culture Isolator 1.5 microbial tubes, without prior cultivation, is a promising approach for the rapid detection of Candida spp. in neonates with suspected candidaemia.

Induction of SAP7 Correlates with Virulence in an Intravenous Infection Model of Candidiasis but Not in a Vaginal Infection Model in Mice  

Digital Repository Infrastructure Vision for European Research (DRIVER)

SAP7 of Candida albicans is induced after vaginal infection of mice. Conversely, virulence during vaginal infection was not affected in a ?sap7/?sap7 mutant strain. Only a partial virulence phenotype was detectable after intravenous injection. In conclusion, SAP7 expression does not correlate with C. albicans virulence in mice.
