    Patients with a history of chemotherapy or stem cell transplantation (SCT) and prolonged neutropenia are at risk for hepatic and/or splenic seeding of Candida . In our experience, hepatosplenic candidiasis (HSC) without documented candidemia often remains unrecognized. We describe three cases of HSC without documented candidemia and the challenges in establishing the diagnosis and adequately treating this condition. The first patient had a history of SCT for treatment of breast cancer and was scheduled for hemihepatectomy for suspected liver metastasis. A second opinion at our institute resulted in the diagnosis of hepatic candidiasis without prior documented candidemia, for which she was treated successfully with fluconazole. The second case demonstrates the limitations of (blood and tissue) cultures and the value of molecular methods to confirm the diagnosis. Case 3 illustrates treatment challenges, with ongoing dissemination and insufficient source control despite months of antifungal therapy, eventually resulting in a splenectomy. A structured literature search was performed for articles describing any patient with HSC and documented blood culture results. Thirty articles were available for extraction of data on candidemia and HSC. Seventy percent (131/187) of patients with HSC did not have documented candidemia. The majority of HSC events were described in hematologic patients, although some cases were described in patients with solid tumors treated with SCT ( n  = 1) or chemotherapy and a history of leukopenia ( n  = 2). Current guidelines and practices for diagnosis and treatment are described. Clinicians should be aware that HSC most often occurs without documented candidemia. In case of persistent or unexplained fever or lesions in the liver and/or spleen, a history of neutropenia should place disseminated candidiasis in the differential diagnosis. HSC is not limited to hematological patients and may occur in patients with solid tumors treated with

    Full Text Available Introduction. The Royal College of Surgeons in England published guidelines in 2008 outlining the information that should be documented at each surgery. St. James’s Hospital uses a standard operation sheet for all surgical procedures and these were examined to assess documentation standards. Objectives. To retrospectively audit the hand written orthopaedic operative notes according to established guidelines. Methods. A total of 63 operation notes over seven months were audited in terms of date and time of surgery, surgeon, procedure, elective or emergency indication, operative diagnosis, incision details, signature, closure details, tourniquet time, postop instructions, complications, prosthesis, and serial numbers. Results. A consultant performed 71.4% of procedures; however, 85.7% of the operative notes were written by the registrar. The date and time of surgery, name of surgeon, procedure name, and signature were documented in all cases. The operative diagnosis and postoperative instructions were frequently not documented in the designated location. Incision details were included in 81.7% and prosthesis details in only 30% while the tourniquet time was not documented in any. Conclusion. Completion and documentation of operative procedures were excellent in some areas; improvement is needed in documenting tourniquet time, prosthesis and incision details, and the location of operative diagnosis and postoperative instructions.

    Background: The aim of this study was to conduct external validation of risk prediction scores for invasive candidiasis. Methods: We conducted a prospective observational study in a 12-bedded adult medical/surgical Intensive Care Unit (ICU) to evaluate Candida score >3, colonization index (CI) >0.5, corrected CI >0.4 (CCI), and Ostrosky's clinical prediction rule (CPR). Patients' characteristics and risk factors for invasive candidiasis were noted. Patients were divided into two groups; invasive candidiasis and no-invasive candidiasis. Results: Of 198 patients, 17 developed invasive candidiasis. Discriminatory power (area under receiver operator curve [AUROC]) for Candida score, CI, CCI, and CPR were 0.66, 0.67, 0.63, and 0.62, respectively. A large number of patients in the no-invasive candidiasis group (114 out of 181) were exposed to antifungal agents during their stay in ICU. Subgroup analysis was carried out after excluding such patients from no-invasive candidiasis group. AUROC of Candida score, CI, CCI, and CPR were 0.7, 0.7, 0.65, and 0.72, respectively, and positive predictive values (PPVs) were in the range of 25%–47%, along with negative predictive values (NPVs) in the range of 84%–96% in the subgroup analysis. Conclusion: Currently available risk prediction scores have good NPV but poor PPV. They are useful for selecting patients who are not likely to benefit from antifungal therapy. PMID:28904481

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    Full Text Available Background and Purpose: Vulvovaginal candidiasis is a frequent disease affecting approximately more than %75 of all childbearing women at least once in their lifetime by overgrowth of opportunistic Candida species. Recurrent vulvovaginal candidiasis (RVVC is common in otherwise healthy individuals. Several risk factors were reported to contribute to RVVC susceptibility. A polymorphism in Dectin-1 (Y238X, rs16910526 was identified in patients with RVVC and hypothesized that genetic factors play an important role in susceptibility to RVVC. Herein, we aimed to survey the polymorphisms in the Dectin-1 gene, linked to susceptibility to RVVC. Materials and Methods: In the current study, blood samples were obtained from 25 patients who had frequent vulvovaginal candidiasis relapses and were diagnosed as RVVC. In addition, blood cultures were obtained from control group comprising of healthy individuals (n=25 with no history of RVVC, vaginal discharge, or itching on the day of examination. Dectin-1 Y238X gene polymorphism was investigated using Bi-PASA and DNA sequencing. Results: The analysis revealed that all of the patients were wild-type homozygous for Dectin-1 Y238X polymorphisms. None of the individuals showed heterozygous or mutant homozygous Dectin-1 polymorphism. Conclusion: No significant correlations were observed between the susceptibility to RVVC and Dectin-1 Y238X polymorphism in the Iranian population, which was not previously studied.

    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)

    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.

    Interleukin 12Rβ1 (IL-12Rβ1)-deficient patients are prone to clinical disease caused by mycobacteria, Salmonella, and other intramacrophagic pathogens, probably because of impaired interleukin 12-dependent interferon γ production. About 25% of patients also display mucocutaneous candidiasis, probably owing to impaired interleukin 23-dependent interleukin 17 immunity. The clinical features and outcome of candidiasis in these patients have not been described before, to our knowledge. We report here the clinical signs of candidiasis in 35 patients with IL-12Rβ1 deficiency. Most (n = 71) of the 76 episodes of candidiasis were mucocutaneous. Isolated oropharyngeal candidiasis (OPC) was the most common presentation (59 episodes, 34 patients) and was recurrent or persistent in 26 patients. Esophageal candidiasis (n = 7) was associated with proven OPC in 2 episodes, and cutaneous candidiasis (n = 2) with OPC in 1 patient, whereas isolated vulvovaginal candidiasis (VVC; n = 3) was not. Five episodes of proven invasive candidiasis were documented in 4 patients; 1 of these episodes was community acquired in the absence of any other comorbid condition. The first episode of candidiasis occurred earlier in life (median age±standard deviation, 1.5 ± 7.87 years) than infections with environmental mycobacteria (4.29 ± 11.9 years), Mycobacterium tuberculosis (4 ± 3.12 years), or Salmonella species (4.58 ± 4.17 years) or other rare infections (3 ± 11.67 years). Candidiasis was the first documented infection in 19 of the 35 patients, despite the vaccination of 10 of these 19 patients with live bacille Calmette-Guérin. Patients who are deficient in IL-12Rβ1 may have candidiasis, usually mucocutaneous, which is frequently recurrent or persistent. Candidiasis may be the first clinical manifestation in these patients.

    This study compares the proportions of surgical intensive care unit (ICU) patients with delirium detected using the Confusion Assessment Method for the ICU (CAM-ICU) who received administrative documentation for delirium using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, stratified by delirium motoric subtypes. This retrospective cohort study was conducted at a surgical ICU from 06/2012 to 05/2013. Delirium was assessed twice daily and was defined as having ≥1 positive CAM-ICU rating. Delirious patients were categorized into hyperactive/mixed and hypoactive subtypes using corresponding Richmond Agitation Sedation Scales. Administrative documentation of delirium was defined as having ≥1 of 32 unique ICD-9-CM codes. Proportions were compared using Pearson's Chi-square test. Of included patients, 40 % (423/1055) were diagnosed with delirium, and 17 % (183/1055) had an ICD-9-CM code for delirium. The sensitivity and specificity of ICD-9-CM codes for delirium were 36 and 95 %. ICD-9-CM codes for delirium were available for 42 % (95 % CI 35-48 %; 105/253) of patients with hyperactive/mixed delirium and 27 % (95 % CI 20-34 %; 46/170) of patients with hypoactive delirium (relative risk = 1.5; 95 % CI 1.2-2.0; p = 0.002). ICD-9-CM codes yielded a low sensitivity for identifying patients with CAM-ICU positive delirium and were more likely to identify hyperactive/mixed delirium compared with hypoactive delirium.

    Acute disseminated candidiasis is a serious and difficult problem often seen in immunocompromised states. Appearance of a characteristic skin eruption is helpful in the diagnostic. We report below a case report of an eight year old girl with aplastic anemia who had received multiple courses of antibiotics. A profuse monomorphic papular nodular eruption subsequently appeared on the face, palms and soles. Candida tropicalis was identified from the skin biopsy taken from one such lesion.

    Although electronic health record (EHR) systems have potential benefits, such as improved safety and quality of care, most ophthalmology practices in the United States have not adopted these systems. Concerns persist regarding potential negative impacts on clinical workflow. In particular, the impact of EHR operating room (OR) management systems on clinical efficiency in the ophthalmic surgery setting is unknown. To determine the impact of an EHR OR management system on intraoperative nursing documentation time, surgical volume, and staffing requirements. For documentation time and circulating nurses per procedure, a prospective cohort design was used between January 10, 2012, and January 10, 2013. For surgical volume and overall staffing requirements, a case series design was used between January 29, 2011, and January 28, 2013. This study involved ophthalmic OR nurses (n = 13) and surgeons (n = 25) at an academic medical center. Electronic health record OR management system implementation. (1) Documentation time (percentage of operating time documenting [POTD], absolute documentation time in minutes), (2) surgical volume (procedures/time), and (3) staffing requirements (full-time equivalents, circulating nurses/procedure). Outcomes were measured during a baseline period when paper documentation was used and during the early (first 3 months) and late (4-12 months) periods after EHR implementation. There was a worsening in total POTD in the early EHR period (83%) vs paper baseline (41%) (P system implementation was associated with worsening of intraoperative nursing documentation time especially in shorter procedures. However, it is possible to implement an EHR OR management system without serious negative impacts on surgical volume and staffing requirements.

    2010-01-01

    Candidiasis, an often encountered oral disease, has been increasing in frequency. Most commonly caused by the overgrowth of Candida albicans, oral candidiasis can be divided into several categories including acute and chronic forms, and angular cheilitis. Risk factors for the development of oral candidiasis include immunosuppression, wearing of dentures, pharmacotherapeutics, smoking, infancy and old age, endocrine dysfunction, and decreased salivation. Oral candidiasis may be asymptomatic. More frequently, however, it is physically uncomfortable, and the patient may complain of burning mouth, dysgeusia, dysphagia, anorexia, and weight loss, leading to nutritional deficiency and impaired quality of life. A plethora of antifungal treatments are available. The overall prognosis of oral candidiasis is good, and rarely is the condition life threatening with invasive or recalcitrant disease.

    2017-09-01

    Recurrent vulvovaginal candidiasis (RVVC), multiple episodes of vulvovaginal candidiasis (VVC; vaginal yeast infection) within a 12-month period, adversely affects quality of life, mental health, and sexual activity. Diagnosis is not straightforward, as VVC is defined by the combination of often nonspecific vaginal symptoms and the presence of yeast-which is a common vaginal commensal. Estimating the incidence and prevalence is challenging: most VVC is diagnosed and treated empirically, the availability for purchase of effective therapies over the counter enables self-diagnosis and treatment, and the duration of the relatively benign VVC symptoms is short, introducing errors into any estimates relying on medical records or patient recall. We evaluate current estimates of VVC and RVVC and provide new prevalence estimates using data from a 2011 seven-country (n = 7345) internet panel survey on VVC conducted by Ipsos Health (https://www.ipsos.com/en). We also evaluate information on VVC-associated visits using the National Ambulatory Medical Care Survey. The estimated probability of VVC by age 50 varied widely by country (from 23% to 49%, mean 39%), as did the estimated probability of RVVC after VVC (from 14% to 28%, mean 23%). However estimated, the probability of RVVC was high suggesting RVVC is a common condition. Copyright © 2017 Elsevier Inc. All rights reserved.

    2008-04-01

    To review the epidemiology, diagnosis and changing treatment paradigm of ocular candidiasis, and report current prevalence rates and risk factors at one inpatient hospital. Retrospective review; systematic literature review. All Wills Eye Institute inpatient ophthalmology consultations from Thomas Jefferson University Hospital were retrospectively reviewed between June 2006 and November 2006. All consultations for candidaemia were included. The outcome variables included chorioretinitis, endophthalmitis, visual symptoms and Candida speciation. The ophthalmic literature was reviewed using PubMed. Keywords included Candida, candidaemia, chorioretinitis, vitritis and endophthalmitis. Bibliographies were manually searched. Three of the 38 consultations for candidaemia (7.9%) had chorioretinitis. There were no cases of vitritis or endophthalmitis. The presence of symptoms, or the inability to articulate symptoms, was significantly associated with risk of ocular candidiasis (p = 0.003). All three cases of chorioretinitis had positive blood cultures for Candida albicans (p = 0.089) and were treated with oral fluconazole. Various factors have led to the increasing prevalence of inpatient candidaemia. Risk factors for ocular involvement include albicans species and the presence of, or inability to articulate, visual symptoms. For those without abnormal findings on initial examination, a subsequent retinal examination should be performed in 2 weeks, particularly if new symptoms develop or if the patient is unable to relay symptoms. Patients with chorioretinitis should be treated with systemic antifungal agents. For those with vitritis or endophthalmitis, particularly if worsening on systemic therapy alone, intravitreal antifungal medications or early vitrectomy should be considered.

    Some pediatric surgeons rarely document nonoperative services, believing that the reimbursement provided for such care is negligible. We evaluated the impact of comprehensive documentation and billing for nonoperative, pediatric surgical care. All bills submitted for inpatient, nonoperative care for 1 year were reviewed. Total receipts for documented admissions, consultations, critical care, and daily care were determined. The Evaluation and Management code billed for each service was recorded, and the total and average payments attributable to each Evaluation and Management code were calculated. Fifty-six percent of services were covered by Medicaid and 26% by a commercial insurer. There were 607 billed admission history and physical exams for which reimbursement totaled 43,493 dollars. Critical care services were provided to 49 patients and yielded 8964 dollars in payments. Six hundred thirty-nine inpatient consultations were performed with a reimbursement of 42,830 dollars. Daily care services were billed 1044 times and produced 71,579 dollars in payments. Overall reimbursement for documented, nonoperative services was 166,866 dollars. This represented 16.2% of total, noncontracted income for the practice. Despite a payer mix heavily weighted toward Medicaid, comprehensive documentation and billing for nonoperative services increased total, noncontracted reimbursement by almost 20% over what it would have been had only operative services been billed. The yield from properly documented, nonoperative care can be substantial.

    Changes in health care are stimulating residency training programs to develop new methods for teaching surgical skills. We developed Computer-Enhanced Visual Learning (CEVL) as an innovative Internet-based learning and assessment tool. The CEVL method uses the educational procedures of deliberate practice and performance to teach and learn surgery in a stylized manner. CEVL is a learning and assessment tool that can provide students and educators with quantitative feedback on learning a specific surgical procedure. Methods involved examine quantitative data of improvement in surgical skills. Herein, we qualitatively describe the method and show how program directors (PDs) may implement this technique in their residencies. CEVL allows an operation to be broken down into teachable components. The process relies on feedback and remediation to improve performance, with a focus on learning that is applicable to the next case being performed. CEVL has been shown to be effective for teaching pediatric orchiopexy and is being adapted to additional adult and pediatric procedures and to office examination skills. The CEVL method is available to other residency training programs.

    To describe the most pertinent echographic findings regarding systemic and renal candidiasis in high-risk neonates. Echographic findings and clinical histories of 40 neonates in the neonatal intensive care unit were retrospectively analyzed. Thirty-eight presented systemic candidiasis with renal participation, while two showed only renal candidiasis. Ultrasound scans were performed using 7.5 MHz probes. Alterations in renal echo structure, presence of echogenic material without acoustic shadowing in the excretory system (mycetoma), presence of lithiasis, pyonephrosis and associated renal malformations were all evaluated. Ten patients presented renal alterations in ultrasound scan. Six children had originally shown increased eye-catching in the renal parenchyma which was resolved after medical treatment. Four children presented renal mycetoma, and in two there were renal malformations. Both of these exhibited a profile for pyonephrosis. One patient with renal mycetoma without urological abnormalities developed a lithiasis. Surgical intervention was unnecessary in all cases. The most common echographic findings in immature high-risk low-weight patients with systemic and renal candidiasis were alterations in the eye-catching of renal parenchyma and the presence of mycetoma.

    To determine whether pregnancy status, gynaecological history, date of last menstrual period and contraceptive use are documented in emergency female admissions of reproductive age admitted to general surgery. This is a retrospective study. This study was conducted in the United Kingdom. Females of reproductive age (12-50 years) admitted as an emergency to general surgery with abdominal pain were considered in this study. Retrospective analysis of medical notes of emergency female admissions with abdominal pain between January and September 2012. We recorded whether a pregnancy test result was documented (cycle 1). Results were analysed and a prompt added to the medical clerk-in document. We re-audited (cycle 2) between January and June 2013 looking for improvement. Documented pregnancy status within 24 h of admission and prior to any surgical intervention. 100 case notes were reviewed in stage 1. 30 patients (30 %) had a documented pregnancy status. 32 (32 %), 25 (25 %) and 29 (29 %) had a documented gynaecology history, contraceptive use and date of last menstrual period (LMP), respectively. 24 patients underwent emergency surgery, 6 (25 %) had a documented pregnancy status prior to surgery. Of 50 patients reviewed in stage 2, 37 (75.0 %) had a documented pregnancy status (p contraceptive use (p < 0.0001) documented. 40 patients (80 % had a documented LMP (p < 0.0001). 7 patients required surgery, of whom 6 (85.7 %) had a documented pregnancy test prior to surgery (p = 0.001). All pregnancy tests were negative. A simple prompt in the surgical admission document has significantly improved the documentation of pregnancy status and gynaecological history in our female patients, particularly in those who require surgical intervention. A number of patient safety concerns were addressed locally, but require a coordinated, interdisciplinary discussion and a national guideline. A minimum standard of care, in females of reproductive age, should include mandatory objective

  18. Late Lung Metastasis of a Primary Eccrine Sweat Gland Carcinoma 10 Years after Initial Surgical Treatment: The First Clinical Documentation

    R. F. Falkenstern-Ge

    2013-01-01

    Full Text Available Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    2014-06-01

    We assessed the frequency of oral candidiasis and the association between demographic variables, disease-related variables, corticosteroid treatment, other treatments and the occurrence of oral candidiasis in the Hopkins Lupus Cohort. In this large prospective cohort study of 2258 patients with systemic lupus erythematosus (SLE), demographic and clinical associates of oral candidiasis were estimated by univariate, multivariate and within-person regression models. There were 53,548 cohort visits. Oral candidiasis was diagnosed at 675 visits (1.25%) in 325 (14%) of the patients. In the multivariate analyses, oral candidiasis was associated with African-American ethnicity, SELENA-SLEDAI disease activity, high white blood cell count, a history of bacterial infection, prednisone use and immunosuppressive use. The urine protein by urine dip stick was higher in SLE patients with oral candidiasis. Considering only patients who had candidiasis at some visits in a 'within-person' analysis, candidiasis was more frequent in visits with higher SELENA-SLEDAI disease activity, high white blood cell count, proteinuria by urine dip stick, a history of bacterial infection and prednisone use. The use of hydroxychloroquine was associated with a lower risk of oral candidiasis, but was not statistically significant (p = 0.50) in the within-person analysis models. This study identified multiple risk factors for oral candidiasis in SLE. Inspection of the oral cavity for signs of oral candidiasis is recommended especially in SLE patients with active disease, proteinuria, high white blood cell count, taking prednisone, immunosuppressive drugs or antibiotics. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    2017-01-01

    The incidence of oral candidiasis has increased in the elderly in recent years. Although the increase of the elderly population plays a big role in this rise of oral candidiasis, the broader recognition that elderly people have higher infection rates for oral candidiasis is considered to be also an important factor. Oral candidiasis can be categorized into three types. Pseudomembranous oral candidiasis is characterized by the appearance of white moss, erythematous oral candidiasis by the eruption of erythema, and hyperplastic oral candidiasis by mucosal hyperplasia. Miconazole has been commonly used when treating oral candidiasis. Elderly patients, however, have a tendency to develop oral candidiasis repeatedly. It is therefore critical to take measures to prevent recurrence. We recommend the use an oral moisturizer containing hinokitiol, an antifungal substance, on a regular basis, to help prevent recurrence of oral candidiasis.

    Background We describe the incidence, risk factors, and outcomes of invasive candidiasis in infants >1500 g birth weight. Methods We conducted a retrospective cohort study of infants >1500 g birth weight discharged from 305 NICUs in the Pediatrix Medical Group from 2001–2010. Using multivariable logistic regression, we identified risk factors for invasive candidiasis. Results Invasive candidiasis occurred in 330/530,162 (0.06%) infants. These were documented from positive cultures from ≥1 of these sources: blood (n=323), cerebrospinal fluid (n=6), or urine from catheterization (n=19). Risk factors included day of life >7 (OR 25.2; 95% CI 14.6–43.3), vaginal birth (OR 1.6 [1.2–2.3]), exposure to broad-spectrum antibiotics (OR 1.6 [1.1–2.4]), central venous line (OR 1.8 [1.3–2.6]), and platelet count candidiasis had increased mortality (OR 2.2 [1.3–3.6]). Conclusions Invasive candidiasis is uncommon in infants >1500 g birth weight. Infants at greatest risk are those exposed to broad-spectrum antibiotics and with platelet counts of <50,000/mm3.

    2009-03-01

    The inadequacy of information on the treatment of gastric candidiasis with antifungal agents promoted us to evaluate patients with fungal infections who had gastric ulcers and assess the need for proton-pump inhibitors or antifungal agents. Sixteen patients were included in the study. The criterion for the diagnosis of candidiasis was finding yeast and hyphae in the tissue or an ulcer on histological sections of biopsy samples. Surface fungi were not considered infections. In all cases with benign ulcers, follow-up endoscopy performed 6 weeks after proton-pump-inhibitor treatment revealed that the ulcer had improved without antifungal medication. However, in patients with malignant ulcers, surgical resection was necessary for a definitive cure. Two patients with lymphoma received combined chemotherapy and a proton-pump inhibitor, which improved their condition. The results of this study suggest that benign ulcers with candidiasis can be effectively treated by a proton-pump inhibitor without antifungal medication. However, surgical resection should be considered for malignant ulcers with candidiasis.

    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.

    This study evaluated the effectiveness of antimicrobial photodynamic therapy (aPDT) in the treatment of oral candidiasis in a murine model using Photodithazine® (PDZ). This model of oral candidiasis was developed to allow the monitoring of the infection and the establishment of the aPDT treatment. Six-week-old female mice were immunosuppressed and inoculated with C. albicans to induce oral candidiasis. PDZ-mediated aPDT and nystatin treatment were carried out for 5 consecutive days with one application per day. The macroscopic evaluation of oral lesions was performed. After each treatment, the tongue was swabbed to recover C. albicans cells. Viable colonies were quantified and the number of CFU/ml determined. The animals were sacrificed 24 hours and 7 days after treatment and the tongues were surgically removed for histological analysis and analysis of inflammatory cytokines expression (IL-1, TNF-α and IL-6) by RT-qPCR. Data were analyzed by two-way ANOVA. PDZ-mediated aPDT was as effective as Nystatin (NYS group) in the inactivation of C. albicans, reducing 3 and 3.2 logs10 respectively, 24 h after treatment (poral lesions, while animals treated with NYS presented partial remission of oral lesions in both periods assessed. Histological evaluation revealed mild inflammatory infiltrate in the groups treated with aPDT and NYS in both periods assessed. The aPDT induced the TNF-α expression when compared with the control (P-L-) (poral candidiasis.

  11. Invasive Candidiasis: An Overview from Taiwan

    2009-06-01

    Full Text Available Invasive candidiasis has emerged as an important nosocomial infection, especially in critically ill patients. We review the epidemiology of invasive candidiasis with an emphasis on data from Taiwan. An increasing incidence of candidemia became apparent from 1980 to the end of the 1990s, followed by relative stability. Crude mortality rates of patients with candidemia were in the range of 35% to 60%. Candida albicans remains the predominant cause of invasive candidiasis in Taiwan and accounts for more than 50% of all cases. Candida tropicalis, Candida glabrata and Candida parapsilosis are the three most common nonalbicansCandida species that cause invasive candidiasis. The above four Candida species account for more than 90% of invasive candidiasis in Taiwan. Overall, invasive Candida isolates have remained highly susceptible to fluconazole (> 90% susceptibility over the past two decades. However, periodic surveillance is needed to monitor antifungal resistance because reduced fluconazole susceptibility in non-albicans Candida is not an uncommon trend. Voriconazole and echinocandins continue to exhibit excellent in vitro activity against invasive Candida isolates.

    Skin lesions associated with Candida septicaemia occur only in a minority of patients, who are usually immunocompromised, but they can help to establish a diagnosis rapidly. The lesions form a characteristic maculopapular or nodular rash at the onset of the infection. We report three cases of systemic candidiasis (SC) with cutaneous manifestations in immunocompromised patients. In these patients, the lesions started as asymptomatic or slightly pruriginous macules, papules or nodules localized on the trunk and extremities. The patients' general condition was very poor and they presented a high fever at the onset of the illness. Candida spp. were isolated from blood in all cases, and histology showed yeasts in two of them. Most of the lesions resolved with antifungal treatment. The diagnosis of SC is often delayed or missed because of the absence of useful diagnostic tools, the varying clinical manifestations and the frequent negativity (50-75%) of blood cultures for Candida. Fluconazole is the treatment of choice for Candida albicans, but treatment response is unknown for other Candida spp., which may require treatment with amphotericin B.

    A 47-year-old woman presented with persistent dysphagia. A gastroendoscopy revealed massive esophageal candidiasis, and oral miconazole was prescribed. Three weeks later, she returned to our hospital without symptomatic improvement. She was febrile, and blood tests showed leukocytosis (137,150 /μL, blast 85%), anemia and thrombocytopenia. She was diagnosed with acute myeloid leukemia (AML). She received chemotherapy and antimicrobial agents. During the recovery from the nadir, bilateral ocular candidiasis was detected, suggesting the presence of preceding candidemia. Thus, esophageal candidiasis can be an initial manifestation of AML. Thorough examination to detect systemic candidiasis is strongly recommended when neutropenic patients exhibit local candidiasis prior to chemotherapy.

    Clinical data on patients with intra-abdominal candidiasis (IAC) is still scarce. We collected data from 13 hospitals in Italy, Spain, Brazil, and Greece over a 3-year period (2011-2013) including patients from ICU, medical, and surgical wards. A total of 481 patients were included in the study. Of these, 27% were hospitalized in ICU. Mean age was 63 years and 57% of patients were male. IAC mainly consisted of secondary peritonitis (41%) and abdominal abscesses (30%); 68 (14%) cases were also candidemic and 331 (69%) had concomitant bacterial infections. The most commonly isolated Candida species were C. albicans (n = 308 isolates, 64%) and C. glabrata (n = 76, 16%). Antifungal treatment included echinocandins (64%), azoles (32%), and amphotericin B (4%). Septic shock was documented in 40.5% of patients. Overall 30-day hospital mortality was 27% with 38.9% mortality in ICU. Multivariate logistic regression showed that age (OR 1.05, 95% CI 1.03-1.07, P < 0.001), increments in 1-point APACHE II scores (OR 1.05, 95% CI 1.01-1.08, P = 0.028), secondary peritonitis (OR 1.72, 95% CI 1.02-2.89, P = 0.019), septic shock (OR 3.29, 95% CI 1.88-5.86, P < 0.001), and absence of adequate abdominal source control (OR 3.35, 95% CI 2.01-5.63, P < 0.001) were associated with mortality. In patients with septic shock, absence of source control correlated with mortality rates above 60% irrespective of administration of an adequate antifungal therapy. Low percentages of concomitant candidemia and high mortality rates are documented in IAC. In patients presenting with septic shock, source control is fundamental.

    Candidiasis is defined as an infection or disease caused by a fungus of the genus Candida. Rate of disseminated candidiasis increases with the growth of the number of immunocompromised patients. In the the last few decades the incidence of disseminated candidiasis is in growth as well as the mortality rate. The aim of this survey is to show the importance of serological tests implementation in disseminated candidiasis diagnose. This is a prospective study involving 60 patients with malign diseases with and without clinical signs of disseminated candidiasis and 30 healthy people who represent the control group. Apart from hemoculture, detection of circulating mannan antigen and adequate antibodies of Candida species applying comercial ELISA test was determined in each patient. This survey deals with relevant factors causing disseminated candidiasis. This survey showed that the group of patients with clinical signs of disseminated candidiasis had more patients with positive hemoculture to Candida species, then the group of patients without clinical signs of disseminated candidiasis. The number of patients being examined and positive to antigens and antibodies was higher (p candidiasis (7/30; 23.3%), then in the group of patients without clinical signs of disseminated candidiasis (0/30; 0%): Average value of titra antigen was statistically higher (p candidiasis 6/30 (20%) of patients had Candida spp.positive hemocultures while in the group of patients without clinical signs of disseminated candidiasis 1/30 (3.3%) of patients had Candida spp. positive hemocultures, which was considerably higher (p candidiasis were statistically significant, while correlation of results of hemoculture and antibodies was insignificant. Because of low sensitivity of hemoculture and time needed for isolation of Candida spp., introducing serological tests in regular procedures would speed disseminated candidiasis diagnose.

    Full Text Available Candidiasis is a multifaceted fungal disease including mucosal-cutaneous, visceral, and disseminated infections caused by yeast species of the genus Candida. Candida infections are among the most common human mycoses. Candida species are the third to fourth most common isolates from bloodstream infections in neutropenic or immunocompromised hospitalized patients. The mucosal-cutaneous forms—particularly vaginal infections—have a high prevalence. Vaginitis caused by Candida species is the second most common vaginal infection. Hence, candidiasis is a major subject for research, including experimental in vivo models to study pathogenesis, prevention, or therapy of the disease. The following review article will focus on various experimental in vivo models in different laboratory animals, such as mammals (mice, rats, rabbits, the fruit fly–Drosophila melanogaster, the larvae of the moth Galleria mellonella, or the free-living nematode Caenorhabditis elegans. The review will describe the induction of the different clinical forms of candidiasis in the various models and the validity of such models in mimicking the human clinical situations. The use of such models for the assessment of antifungal drugs, evaluation of potential vaccines to protect before candidiasis, exploration of Candida virulence factors, and comparison of pathogenicity of different Candida species will be included in the review. All of the above will be reported as based on published studies of numerous investigators as well as on the research of the author and his group.

    Full Text Available 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.

    A diagnosis of systemic candidiasis is often delayed or missed owing to the absence of sensitive, specific, and timely diagnostic tools. Skin lesions are not common, but they can help to rapidly establish a diagnosis. We report on a 14-year experience of systemic candidiasis with skin lesions in our institution. We report the prevalence, clinical findings, histologic findings, etiologic Candida species, underlying conditions, treatment modalities, and outcomes of the cases and compare them with the previous reports. We reviewed the medical records and laboratory data of patients diagnosed with systemic candidiasis from June 1989 to September 2002 at Asan Medical Center, Seoul, Korea. We thoroughly reviewed the data on those patients with characteristic skin lesions. We included the cases in which Candida organisms were either shown or cultured from the skin. We also included the patients who had developed the characteristic rash at the onset of infection if there was no other possible explanation for the rash. Of 53 documented systemic candidiasis cases, 19 (35.8%) had the characteristic skin lesions. Fifteen patients (78.9%) had hematologic problems and were neutropenic. The skin lesions were a maculopapular or nodular rash and plaques. In addition to the trunk and proximal extremities, the rash also involved the face and distal extremities. The rashes were mostly purpuric, not consistently associated with underlying thrombocytopenia but also associated with underlying vascular damage as a result of Candida organisms. The underlying vascular damage also caused intraepidermal necrotic and vesicular change. One case of transepidermal elimination of organisms was newly found. The most common causative species was Candida tropicalis in the 19 patients with skin lesions, in contrast with Candida albicans in a total of 53 patients. The mortality rate was 84.2%. The prevalence of systemic candidiasis-associated skin lesions may be higher than previously reported

    Vulvovaginal candidiasis is common infection among those affecting the vulva and vagina. Is caused by the perpesentatives from the genus Candida, in most cases C. albicans (85-90%). An increase in the percentage of the so-called non-albicans agents is seen and these pathgogens are often resistant to the most commonly used in the practice antifungals. Faulty diagnosis, incorrect use of azoles, and self-treatment lead to selection of resistant strains and recurrent infections. Identification of Candida species associated with vulvovaginal candidiasis by conventional and PCR techniques. For six months a total number of 213 vaginal secretions were tested applying Gram stain and cultivation on ChromAgar. API Candida fermentation tests and API 20CAUX assimilation tests were performed for the identification of the bacteria. Extraction of DNA of all the smears with subsequent PCR detection of different Candida species were done. 80.7% materials showed presence of blastospores and/or hyphae. Positive culture results were detected in 60 (28.2%) samples. The species specific identification revealed presence of C. albicans in 51 (85%) smears, C. glabrata--in 8 (13.3%), C. krusei--in 2 (3.3%), and S. cervisie--in 1 (2.1%). The PCR technique confirmed the results of the conventional methods. It is worth to mention that 51 of the tested smears were positive for G. vaginalis using additional PCR. The correct diagnosis of the cause of vulvovaginal candidiasis helps in the correct choice of appropriate antifungal therapy and prevents development of recurrent infections and consequences. The PCR based method is rapid, specific and sensitive. It perfectly correlates with the results from the conventional diagnostic tests so it could be selected as a method of choice for the diagnosis of vulvovaginal candidiasis.

    Candidemia and disseminated candidiasis are major causes of morbidity and mortality in hospitalized patients especially in the intensive care units (ICU). The incidence of invasive candidasis is on a steady rise because of increasing use of multiple antibiotics and invasive procedures carried out in the ICUs. Worldwide there is a shifting trend from C. albicans towards non albicans species, with an associated increase in mortality and antifungal resistance. In the ICU a predisposed host in one who is on broad spectrum antibiotics, parenteral nutrition, and central venous catheters. There are no pathognomonic signs or symptoms. The clinical clues are: unexplained fever or signs of severe sepsis or septic shock while on antibiotics, multiple, non-tender, nodular erythematous cutaneous lesions. The spectrum of infection with candida species range from superficial candidiasis of the skin and mucosa to more serious life threatening infections. Treatment of candidiasis involves removal of the most likely source of infection and drug therapy to speed up the clearance of infection. Amphotericin B remains the initial drug of first choice in hemodynamically unstable critically ill children in the wake of increasing resistance to azoles. Evaluation of newer antifungal agents and precise role of prophylactic therapy in ICU patients is needed.

    Despite therapeutic advances candidiasis remains a common fungal infection most frequently caused by C. albicans and may occur as vulvovaginal candidiasis or thrush, a mucocutaneous candidiasis. Candidiasis frequently occurs in newborns, in immune-deficient people like AIDS patients, and in people being treated with broad spectrum antibiotics. It is mainly due to C. albicans while other species such as C. tropicalis, C. glabrata, C. parapsilosis and C. krusei are increasingly isolated. OTC antifungal dosage forms such as creams and gels can be used for effective treatment of local candidiasis. Whereas, for preventing spread of the disease to deeper vital organs, candidiasis antifungal chemotherapy is preferred. Use of probiotics and development of novel vaccines is an advanced approach for the prevention of candidiasis. Present review summarizes the diagnosis, current status and challenges in the treatment and prevention of candidiasis with prime focus on host defense against candidiasis, advancements in diagnosis, probiotics role and recent progress in the development of vaccines against candidiasis.

  10. Experimental Oral Candidiasis in Animal Models

    2001-01-01

    Oral candidiasis is as much the final outcome of the vulnerability of the host as of the virulence of the invading organism. We review here the extensive literature on animal experiments mainly appertaining to the host predisposing factors that initiate and perpetuate these infections. The monkey, rat, and mouse are the choice models for investigating oral candidiasis, but comparisons between the same or different models appear difficult, because of variables such as the study design, the number of animals used, their diet, the differences in Candida strains, and the duration of the studies. These variables notwithstanding, the following could be concluded. (i) The primate model is ideal for investigating Candida-associated denture stomatitis since both erythematous and pseudomembranous lesions have been produced in monkeys with prosthetic plates; they are, however, expensive and difficult to obtain and maintain. (ii) The rat model (both Sprague-Dawley and Wistar) is well proven for observing chronic oral candidal colonization and infection, due to the ease of breeding and handling and their ready availability. (iii) Mice are similar, but in addition there are well characterized variants simulating immunologic and genetic abnormalities (e.g., athymic, euthymic, murine-acquired immune deficiency syndrome, and severe combined immunodeficient models) and hence are used for short-term studies relating the host immune response and oral candidiasis. Nonetheless, an ideal, relatively inexpensive model representative of the human oral environment in ecological and microbiological terms is yet to be described. Until such a model is developed, researchers should pay attention to standardization of the experimental protocols described here to obtain broadly comparable and meaningful data. PMID:11292645

    2009-06-01

    Full Text Available Background: Oral candidiasis is a common opportunistic infection of the oral cavity caused by an overgrowth of Candida species, the commonest being Candida albicans. Candida albicans is a harmless commensal organism inhabiting the mouths but it can change into pathogen and invade tissue and cause acute and chronic disease. Dentures predispose to infection with Candida in as many as 65% of elderly people wearing full upper dentures. Purpose: The purpose of this case report is to discuss thrush in patient wearing full denture which rapidly developed. Case: This paper report a case of 57 year-old man who came to the Oral Medicine Clinic Faculty of Dentistry Airlangga University with clinical appearance of pseudomembranous candidiasis (thrush. Case Management: Diagnosis of this case is confirmed with microbiology examination. Patient was wearing full upper dentures, and from anamnesis known that patient wearing denture for 24 hours and he had poor oral hygiene. Patient was treated with topical (nystatin oral suspension and miconazole oral gel and systemic (ketoconazole antifungal. Patient also instructed not to wear his denture and cleaned white pseudomembrane on his mouth with soft toothbrush. Conclusion: Denture, habit of wearing denture for 24 hours, and poor oral hygiene are predisposing factors of thrush and it can healed completely after treated with topical and systemic antifungal.

    Candidais an opportunistic pathogen that causes mucosal and deep systemic candidiasis. The emergence of drug resistance and the side effects of currently available antifungals have restricted their use as long-term prophylactic agents for candidal infections. Given this scenario, probiotics have been suggested as a useful alternative for the management of candidiasis. We analyzed the available data on the efficacy of probiotics in candidal colonization of host surfaces. A number of well-controlled studies indicate that probiotics, particularly lactobacilli, suppressCandidagrowth and biofilm development in vitro.A few clinical trials have also shown the beneficial effects of probiotics in reducing oral, vaginal, and enteric colonization byCandida; alleviation of clinical signs and symptoms; and, in some cases, reducing the incidence of invasive fungal infection in critically ill patients. Probiotics may serve in the future as a worthy ally in the battle against chronic mucosal candidal infections. © The Author 2016.

    Genotype characteristics and distribution of commensal Candida albicans should be studied to predict the development of candidiasis, however, extensive genotype analysis of commensal C. albicans has not been made. In this study, 508 C. albicans isolates were collected from patients with/without candidiasis and divided into 4 isolate groups (SG-1, oral cavity of non-candidiasis patients; SG-2, patients with cutaneous candidiasis; SG-3, patients with vaginal candidiasis; SG-4, patients with candidemia). These isolates were characterized to study the relationship between genotypes and pathogenicity using microsatellite analysis. Using CDC3 and CAI, 5 genotypes (I, 111: 115/33: 41; II, 115: 119/23: 23; III, 115: 123/18: 27; IV, 115: 123/33: 40; and V, 123: 127/32: 41) were found in 4.2%, 8.9%, 7.1%, 2.2% and 3.1% of the isolates, respectively. Genotypes II and III were commonly found in all isolate groups. These genotypes were further divided into 28 types by additional HIS3 and CAIII microsatellite markers. In this analysis, C. albicans with type 6 and type 23 was widely distributed as a commensal species in the oral cavity of non-candidiasis patients and found to be related with candidiasis development. Additionally, genotypes I and IV were found in SG-2 and/or SG-4, suggesting that the fungus with those genotypes is also involved in this development. In contrast, genotype V was not identified in any infective isolates.

    Oropharyngeal candidiasis in 512 HIV-infected patients at the late stages of the disease was studied with special reference to the clinical and microbiological characteristics of this condition. The diagnosis was established based on the results of the clinical and microbiological examination of the patients including investigation of the tissue samples taken from the oral cavity and the throat with the use of the device specially developed for this purpose. It was shown that the disease existed in various clinical forms the most common of which were monocomponent pathology represented by pseudomembranous candidiasis in 37.5±2.14% of the patients, the two-component mixed form (pseudomembranous candidiasis with concomitant angular chelitis) diagnosed in 27.5±1.97% cases, and the ternary form (the combination of pseudomembranous candidiasis, acute atrophic process, and angular chelitis) documented in 11.9±1.43% patients. The main clinical features of the disease included the combination of its various forms, multiple localization of the pathological process, and its polymorphous manifestations. Changes in the clinical course of oropharyngeal candidiasis associated with the progression of HIV from the 4A to the 4B stage were detected for the first time. They were shown to be accompanied by variations in the species composition and concentration of fungal flora in the crypts of the palatine tonsils and its sensitivity to fluconazole therapy.

    2016-01-01

    Vulvovaginal candidiasis (VVC) is a high-incidence disease seriously affecting the quality of life of women worldwide, particularly in its chronic, recurrent forms (RVVC), and with no definitive cure or preventive measure. Experimental studies in currently used rat and mouse models of vaginal candidiasis have generated a large mass of data on pathogenicity determinants and inflammation and immune responses of potential importance for the control of human pathology. However, reflection is necessary about the relevance of these rodent models to RVVC. Here we examine the chemical, biochemical, and biological factors that determine or contrast the forms of the disease in rodent models and in women and highlight the differences between them. We also appeal for approaches to improve or replace the current models in order to enhance their relevance to human infection. PMID:26883592

    To review the evidence and provide recommendations on screening for and management of vulvovaginal candidiasis, trichomoniasis, and bacterial vaginosis. OUTCOMES evaluated include the efficacy of antibiotic treatment, cure rates for simple and complicated infections, and the implications of these conditions in pregnancy. Published literature was retrieved through searches of MEDLINE, EMBASE, CINAHL, and The Cochrane Library in June 2013 using appropriate controlled vocabulary (e.g., vaginitis, trichomoniasis, vaginal candidiasis) and key words (bacterial vaginosis, yeast, candidiasis, trichomonas vaginalis, trichomoniasis, vaginitis, treatment). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits, but results were limited to English or French language materials. Searches were updated on a regular basis and incorporated in the guideline to May 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). Summary Statements 1.

    Esophageal candidiasis is one of the most common opportunistic infections in patients infected by human immunodeficiency virus (HIV). This pathology is also found in patients without overt immunodeficiency. Other risk factors are known to be associated with this disease like inhaled or systemic corticosteroid treatment or proton-pump inhibitors and H2 receptor antagonists. In the absence of identified risk factors, a primary immune deficiency should be sought. Prevention of esophageal candidiasis is based primarily on the identification of risk factors, and a better control of them. This article presents a review of the physiopathology, clinical presentation and management of esophageal candidiasis by primary care physicians. We will also discuss ways of preventing esophageal candidiasis when necessary.

    Full Text Available Congenital cutaneous candidiasis (CCC is an extremely rare disorder that presents within the first 6 days of life. The manifestations ranges from diffuse skin eruption without any systemic symptoms to respiratory distress, hepatosplenomegaly, sepsis, and death. We report a neonate who presented with generalized skin eruptions at birth, characterized by erythematous macules and papules. The eruption involved head, face, neck, trunk, and extremities. Candida albicans was demonstrated on direct KOH smear, skin biopsy. The disease implies a congenital intrauterine infection and is different from neonatal candidiasis, which manifests as thrush or diaper dermatitis. The infection is acquired from the maternal genital tract in an ascending fashion. Clinical features, direct smear examination of specimen, and appropriate cultures are useful in differentiating the lesions from other more common dermatoses of the neonatal period. Topical antifungal therapy is sufficient unless systemic candidiasis is present. Prognosis for congenital cutaneous candidiasis is good.

In women with vulvovaginal candidiasis: L. iners (6.5%), L. cripatus (79.0%), L. gasseri (37.1%), L. jensenii (74.2%), L. acidophilus (16.1%), L. brevis (19.4%), L. plantarum (1.6%), L. johnsonii (51.6%), L. fermentum (8.1%), L. salivarius (9.7%), L. reuter (1.6%), L. paracasei (8.1%), L. delbrueckii (3. 2% ) ; More than two different Lactobacillus species coexisted in 98% of women with vulvovaginal candidiasis, and no anyone species existed in 2% of them; In fertile women: L. iners (82.6%), L. cripatus (70.7%), L. gasseri (67.4%), L. jensenii (40.2%), L. acidophilus (39.1%), L. brevis (23.9%), L. plantarum (5.4%), L. rhamnosus (1.1%), L. paracasei (1.1%), L. reuter (1.1%) i, L. johnsonii (3.3%), L. fermentum (2.2%), L. salivarius (2.2%); More than two different Lactobacillus species coexisted in 97% of fertile women, and only one species existed in 3% of fertile women. Species of lactobacillus in women with vulvovaginal candidiasis did not significantly reduced compared with healthy women. Lactobacillus inert may be a marker of the change of vaginal microenvironment; Lactobacillus crispatus is a dominant lactobacillus in the vaginal of fertile healthy women, pregnant women and women with vulvovaginal candidiasis.

    An adult male mandrill (Mandrillus sphinx) suffered from chronic ulceration of the facial and gluteal skin and the oral and nasal mucosa. The ulcers were resistant to therapy and led to deterioration in the general condition of the animal. Microscopical examination revealed a severe, chronic, multifocal, granulomatous and eosinophilic dermatitis and panniculitis. There was also stomatitis and rhinitis with numerous intralesional fungal elements. These organisms were identified by immunohistochemistry, transmission electron microscopy, polymerase chain reaction and fungal culture as Candida albicans. Species identification was confirmed by MALDI-TOF mass spectrometry. A specific predisposing immunosuppressive factor for the deep chronic mucocutaneous candidiasis was not identified; however, social stress and/or a primary defect in cell-mediated immunity could not be excluded as possible causes for a predisposing immunodeficiency in the animal.

    To examine the presence of markers associated with malignancy, including p53, p21 cyclin-dependent kinase inhibitor 1A, murine double minutes-2, and others, in chronic hyperplastic candidiasis. Immunohistochemical methods were used to examine the expression of p53, murine double minutes-2, p21 cyclin-dependent kinase inhibitor 1A, metallothionein, and proliferating cell nuclear antigen in 42 chronic hyperplastic candidiasis lesions and 11 non-infected control tissues. Terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling was used to examine apoptosis, which was correlated with p53 expression. These markers were measured in lesions of chronic hyperplastic candidiasis that did not show any epithelial dysplasia or histological signs of malignancy. p53 scores were higher in chronic hyperplastic candidiasis than in controls (P = 0.0046). Murine double-minutes 2 levels were not elevated. p21 cyclin-dependent kinase inhibitor 1A was increased in parabasal (P candidiasis lesions showed a similar basal/parabasal metallothionein staining pattern to that seen in normal squamous epithelium. Proliferating cell nuclear antigen was increased (P = 0.0007), as was apoptosis (P = 0.0033). Increased p53 in oral chronic hyperplastic candidiasis suggests an increased potential for malignant change in the epithelium, above that of normal tissues. Further functional investigation is required, as well as clinical follow-up studies. © 2012 Blackwell Publishing Asia Pty Ltd.

    Following large-scale disasters and major complex emergencies, especially in resource-poor settings, emergency surgery is practiced by Foreign Medical Teams (FMTs) sent by governmental and non-governmental organizations (NGOs). These surgical experiences have not yielded an appropriate standardized collection of data and reporting to meet standards required by national authorities, the World Health Organization, and the Inter-Agency Standing Committee's Global Health Cluster. Utilizing the 2011 International Data Collection guidelines for surgery initiated by Médecins Sans Frontières, the authors of this paper developed an individual patient-centric form and an International Standard Reporting Template for Surgical Care to record data for victims of a disaster as well as the co-existing burden of surgical disease within the affected community. The data includes surgical patient outcomes and perioperative mortality, along with referrals for rehabilitation, mental health and psychosocial care. The purpose of the standard data format is fourfold: (1) to ensure that all surgical providers, especially from indigenous first responder teams and others performing emergency surgery, from national and international (Foreign) medical teams, contribute relevant and purposeful reporting; (2) to provide universally acceptable forms that meet the minimal needs of both national authorities and the Health Cluster; (3) to increase transparency and accountability, contributing to improved humanitarian coordination; and (4) to facilitate a comprehensive review of services provided to those affected by the crisis.

    Candida albicans causes mucosal and disseminated candidiasis, which represent serious problems for the rapidly expanding immunocompromised population. Until recently, Th1-mediated immunity was thought to confer the primary protection, particularly for oral candidiasis. However, emerging data indicate that the newly-defined Th17 compartment appears to play the predominant role in mucosal candidiasis.

    To investigate prevalence of invasive candidiasis in a Neonatal Intensive Care Unit and to evaluate oral diseases and Candida spp. colonization in low birth weight preterm newborns. A descriptive epidemiological study performed in two stages. First, prevalence of candidiasis was analyzed in a database of 295 preterm patients admitted to hospital for over 10 days and birth weight less than 2,000g. In the second stage, oral changes and Candida spp. colonization were assessed in 65 patients weighing less than 2,000g, up to 4 week-old, hospitalized for over 10 days and presenting oral abnormalities compatible with fungal lesions. Swab samples were collected in the mouth to identify fungi. Prevalence of candidiasis was 5.4% in the database analyzed. It correlated with prolonged hospital length of stay (poral mucosa and tongue. Intense oral colonization by Candida spp was observed (80%). The frequency of invasive candidiasis was low and correlated with low birth weight and prolonged hospital stay. The most common oral changes were white plaques compatible with pseudomembranous candidiasis and colonization by Candida spp. was above average.

    Candida spp. are the most common cause of mucosal and disseminated fungal infections in humans. Studies using mutant strains of mice have provided initial information about the roles of dectin-1, CARD9, and Th17 cytokines in the host defense against candidiasis. Recent technological advances have resulted in the identification of mutations in specific genes that predispose humans to develop candidal infection. The analysis of individuals with these mutations demonstrates that dectin-1 is critical for the host defense against vulvovaginal candidiasis and candidal colonization of the gastrointestinal tract. They also indicate that CARD9 is important for preventing both mucosal and disseminated candidiasis, whereas the Th17 response is necessary for the defense against mucocutaneous candidiasis. This article reviews the recent studies of genetic defects in humans that result in an increased susceptibility to candidiasis and discusses how these studies provide new insight into the host defense against different types of candidal infections.

    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.

    Four species of probiotic bacteria were assessed for their capacities to protect athymic bg/bg-nu/nu and euthymic bg/bg-nu/+ mice from mucosal and systemic candidiasis. Each bacterial species and Candida albicans colonized the gastrointestinal tracts of both strains of mice. The presence of probiotic bacteria (Lactobacillus acidophilus, Lactobacillus reuteri, Lactobacillus casei GG, or Bifidobacterium animalis) in the gastrointestinal tracts prolonged the survival of adult and neonatal bg/bg-nu/nu mice compared to that of isogenic mice colonized with C. albicans alone. The incidence of systemic candidiasis in bg/bg-nu/nu mice was significantly reduced by each of the four probiotic bacterial species. The numbers of C. albicans present in the alimentary tracts of euthymic bg/bg-nu/+ mice were significantly reduced by L. casei GG and B. animalis. None of the probiotic bacteria species completely prevented mucosal candidiasis, but B. animalis reduced its incidence and severity. Probiotic bacteria also modulated antibody- and cell-mediated immune responses to C. albicans. The prolonged survival of mice, decreased severity of mucosal and systemic candidiasis, modulation of immune responses, decreased number of C. albicans in the alimentary tract, and reduced numbers of orogastric infections demonstrated not only that probiotic bacteria have biotherapeutic potential for prophylaxis against and therapy of this fungal disease but also that probiotic bacteria protect mice from candidiasis by a variety of immunologic (thymic and extrathymic) and nonimmunologic mechanisms in this model.

    Full Text Available Candidiasis is the second most common vaginal infection. Given the frequent recurrence of the disease, many women tend to use herbal remedies. Thus, the present study aimed to review the association between vaginal candidiasis and herbal medicines in Iran. In this review, we retrieved articles published from 2001 to 2016. Then, the results were expressed both quantitatively and qualitatively. In this study, nine articles were reviewed, which had investigated thyme, garlic, garlic-thyme, olive oil, propolis, myrtus, Nigella sativa (black cumin, and Bunium perscicum boiss (black zira. Subsequently, each of these plants was thoroughly dealt with. The studies on black cumin, garlic, and thyme reported positive effects for these herbs, and they were widely produced for therapeutic purposes. In addition, myrtus was found to have a salutary impact on vaginal candidiasis.

    Full Text Available Invasive candidiasis is a frequent and often fatal complication in immunocompromised and critically ill patients. Unfortunately, the diagnosis of invasive candidiasis remains difficult due to the lack of specific clinical symptoms and a definitive diagnostic method. The detection of antibodies against different Candida antigens may help in the diagnosis. However, the methods traditionally used for the detection of antibodies have been based on crude antigenic fungal extracts, which usually show low-reproducibility and cross-reactivity problems. The development of molecular biology techniques has allowed the production of recombinant antigens which may help to solve these problems. In this review we will discuss the usefulness of recombinant antigens in the diagnosis of invasive candidiasis.

    Neutropenic patients developing acute disseminated candidiasis may present with skin lesions. To evaluate the epidemiology of acute disseminated candidiasis with skin lesions in neutropenic patients, taking into consideration changes caused by different prophylactic strategies. A systematic review of English-language articles found via PubMed (1963-2016) was performed. We asked the following questions: (a) What Candida species are more frequently involved in this syndrome? (b) Has antifungal prophylaxis changed the species causing skin lesions? (c) What are the typical patterns of skin lesions? (d) What is the frequency of skin lesions in neutropenic patients with candidaemia or acute disseminated candidiasis? (e) Has antifungal prophylaxis decreased the incidence of acute disseminated candidiasis with skin lesions? Among 183 studies, 33 were selected, reporting 100 cases of acute disseminated candidiasis with skin lesions in neutropenic patients. It occurred more frequently in the setting of induction therapy for de novo or relapsed acute leukaemia, and the most frequent Candida species were C. tropicalis (68%) and C. krusei (15%). Diffuse maculopapular lesions predominated in cases caused by C. tropicalis and nodular and papular lesions in cases caused by C. krusei. Prophylaxis with fluconazole was reported in six cases, C. krusei in five and C. ciferrii in one. The death rate was 45.4%. Two patterns were recognized: disseminated maculopapular lesions caused by C. tropicalis in patients not receiving fluconazole prophylaxis, occurring in 39% to 44% of neutropenic patients with acute disseminated candidiasis, and nodular lesions caused by C. krusei in patients receiving fluconazole prophylaxis, occurring less frequently.

    Full Text Available Aim. To conduct microbiological reasoning of the formation and development of vulvovaginal candidiasis. To study taxonomic composition and major microbiota and yeast-like fungi of genus Candida and their changes in vulvovaginal content of women with vulvovaginal candidiasis. Materials and methods. Vaginal content of 472 women (19–34 years old with vulvovaginitis was examined. Bacteriological and mycological methods were used. Isolation of yeast-like fungi of the genus Candida was done by seeding of investigated appropriate dilutions of the material on solid nutrient Saburo medium. Species identification was carried out by microscopic, cultural properties and by enzymatic activity. Lactobacillus were isolated and grown on MRS-agar, Bifidobacterium – on modified Blaurock medium, propionic acid bacteria – yeast-serum medium. Analytical parameters characterizing the state of the microbiota of microecological biotope were defined by the commonly accepted methods. Results. The study of taxonomic composition of main microbiota of vulvovaginal content revealed that in the vulvovaginal candidiasis there is expressed deficiency of Lactobacillus and Bifidobacterium and elimination of bacteria of the genus Propionibacterium, which form the physiological basis of indigeneous protective microbiota of the biotope. It was established that C. albicans is most common (constant in the vulvovaginal content of women with vulvovaginal candidiasis (constancy index is 76.67 %. C. zeylanoides belongs to species that are rare in vulvovaginal content, and other species of yeasts-like fungi of genus Candida (C. glabrata, C. inconspiсua, C. krusei, C. tropicalis, C. guilliermondii and C. kefyr – the species that are rare (constancy index ranges from 1.11 to 6.30 %. Conclusions. The essential changes in the taxonomic composition of the main microbiota of vulvovaginal main content (lactobacteria, bifidobacteria and propionic acid bacteria create the preconditions for

    There have been the current Japanese data on susceptibility testing for Candida isolates from vaginal candidiasis. The in vitro activities of therapeutic antifungal drugs for vulvovaginal candidiasis (VVC); miconazole (MCZ), itraconazole (ITCZ), fluconazole (FLCZ), clotrimazole (CTZ), oxiconazole (OCZ), isoconazole (ICZ) and bifonazole (BFZ) against vaginal isolates. Fifty-four strains Candida albicans and 19 strains of Candida glabrata were evaluated using a broth microdilution method specified by Clinical Laboratories Standard Institute (CLSI) document M27-A3. The MIC90 of each drug, MCZ, ITCZ, FLCZ, CTZ, OCZ, ICZ and BFZ, against C. albicans and C. glabrata isolates were 0.25, 0.12, 1, 0.06, 0.12, 0.12 and 1 μg/ml and 1, 1, 8, 0.5, 0.25, 0.5 and 1 μg/ml respectively. The activities of these drugs, except for BFZ, against C. glabrata were lower than that of C. albicans. There was one azole-resistant isolate in C. glabrata of which MIC of FLCZ is > 64 μg/ml and this isolate had cross resistance to other antifungal drugs tested. These results suggest that antifungal drugs for treatment of VVC continues to have potent antifungal activities against C. albicans and C. glabrata isolates from vaginitis. CTZ, OCZ and ICZ susceptibility of FLCZ low susceptibility C. glabrata are relatively higher than MCZ, ITCZ and FLCZ. Copyright © 2015. Published by Elsevier Ltd.

    2015-01-01

    Invasive candidiasis is a leading infectious cause of morbidity and mortality in premature infants. Improved recognition of modifiable risk factors and antifungal prophylaxis have contributed to the recent decline in the incidence of this infection among infants. Invasive candidiasis typically occurs in the first six weeks of life and presents with non-specific signs of sepsis. Definitive diagnosis relies on growth of Candida in blood culture or cultures from other normally sterile sites, but this may identify fewer than half of cases. Improved diagnostics are needed to guide initiation of antifungal therapy in premature infants. PMID:25677999

    FKS mutant Candida isolates were recovered from 24% (6/25) of abdominal candidiasis patients exposed to echinocandin. Candida glabrata (29%) and Candida albicans (14%) mutants were identified. Multidrug-resistant bacteria were recovered from 83% of FKS mutant infections. Mutations were associated with prolonged echinocandin exposure (P = 0.01), breakthrough infections (P = 0.03), and therapeutic failures despite source control interventions (100%).

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.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 after 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.

    Although oropharyngeal candidiasis is associated with inhaled corticosteroid (ICS) usage, there is sparse data on the prevalence of posterior pharyngeal candidiasis in those without any detectable oral candidiasis on clinical examination. We systematically investigated the relationship between oral candidiasis on clinical examination and the presence of posterior pharyngeal candidiasis at bronchoscopy. We conducted a cross-sectional study on a convenience sample of 100 patients undergoing bronchoscopy at our institution. Patients were assessed for symptoms of and risk factors for candida infection and had an examination of their oropharynx for evidence of candidiasis before bronchoscopy. They subsequently had a detailed assessment for posterior candidiasis at bronchoscopy. We performed a posteriori subgroup analysis, which focused solely on those patients on ICS maintenance therapy. Median age was 54.7 (27-84) years, and 55 patients were male; 47 % of patients were on ICS, and 20 % of this cohort received recent oral corticosteroids. Twenty-eight percent of this convenience sample had posterior pharyngeal candidiasis; however, only 10.7 % (3/28) of these patients had clinically detectable oral candidiasis on clinical examination before bronchoscopy. Factors that were independently associated with the presence of pharyngeal candidiasis at bronchoscopy were OR (95 % CI) ICS usage 6.9 (2.5-19.2), particularly fluticasone usage 6.8 (2.62-17.9) and the presence of dysphonia 3.2 (1.3-8.0). In the subgroup analysis of ICS usage, posterior pharyngeal candidiasis was correlated with the presence of dysphonia but was not independently associated with fluticasone or budesonide dosage. This study demonstrates that posterior pharyngeal candidiasis in the absence of clinically overt oral candidiasis is frequent amongst ICS users. A history of ICS use, particularly fluticasone usage, as well as the presence of dysphonia are associated with posterior pharyngeal candidiasis at

    Candidiasis is commonly observed in patients with primary sclerosing cholangitis (PSC), but the clinical risk factors associated with its presence have not been fully investigated. In this study, we aimed to analyse the incidence, risk factors, and transplantation-free survival in primary sclerosing cholangitis (PSC) patients with persistent biliary candidiasis. We retrospectively analysed patients diagnosed with PSC who were admitted to our department during 2002 to 2012. One-hundred fifty patients whose bile cultures were tested for fungal species were selected, and their clinical and laboratory parameters were investigated. The results of endoscopic retrograde cholangiography (ERC) and bile cultures were analysed using chart reviews. The cases of biliary candidiasis were sub-classified as transient or persistent. Thirty out of 150 (20.0%) patients had biliary candidiasis. Although all patients demonstrated comparable baseline characteristics, those with biliary candidiasis showed significantly reduced transplantation-free survival (p candidiasis. A subgroup analysis showed reduced survival with a greater necessity for orthotopic liver transplantation (OLT) only in patients with persistence of Candida (p = 0.007). The survival in the patients with transient biliary candidiasis was comparable to that in candidiasis-free patients. In a multivariate regression analysis that included Mayo risk score (MRS), sex, age, dominant stenosis, inflammatory bowel disease, autoimmune hepatitis overlap syndrome, and number of times ERC was performed, biliary candidiasis was an independent risk factor for reduced survival (p = 0.008). Risk factors associated with acquisition of biliary candidiasis were age at PSC diagnosis and number of ERCs. The persistence of biliary candidiasis is associated with markedly reduced transplantation-free survival in PSC patients. By contrast, actuarial survival in patients with transient biliary candidiasis approaches that for patients without any

    The following article will concentrate on the NDV-3 anti-Candida and Staphylococcus vaccine. The vaccine is composed of the N-terminal portion of the Candida albicans agglutinin-like sequence 3 protein (Als3p) and aluminum hydroxide as adjuvant. The vaccine conferred protection to mice against experimental vaginal, oral, and intravenous challenge with C. albicans. Due to the sequence and structural homology of the Als3p with Staphylococcus aureus surface proteins, the vaccine also protected against experimental skin and IV infection with S. aureus. The vaccine has reached the stage of human trials: phase 1 clinical studies have shown that the vaccine is safe and immunogenic. The latest brief conference abstract reports of vaccination in women suffering from recurrent vaginal candidiasis, indicating that the recurrence rates were lower in the women receiving the vaccine.

    The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

    Hepatosplenic candidiasis is a fungal infection, which mostly affects patients with hematologic malignancies such as leukemia. The pathogenesis of this infection is not clear yet, and the liver is the most commonly affected organ. Diagnosis of hepatosplenic candidiasis can be only established via biopsy, since computed tomography (CT) scan, ultrasonography, and magnetic resonance imaging (MRI) yield non-specific results. The role of fluorine-18 fluorodeoxyglucose positron emission tomography /computed tomography ( 18 F-FDG PET/CT) in diagnosis of hepatosplenic candidiasis remains undetermined, considering a few evidences in the literature. In this case report, we present the case of a 47-year-old patient, affected by acute myeloid leukemia, which was treated with three cycles of chemotherapy, resulting in the development of neutropenia and fever following the last cycle. The 18 F-FDG PET/CT scan showed some foci of intense FDG uptake in the liver and spleen. The subsequent diagnostic investigations (i.e., abdominal CT scan and biopsy) were suggestive of hepatosplenic candidiasis. The patient was started on antifungal treatment with fluconazole. After one month, the clinical conditions were resolved, and the subsequent abdominal CT scan was negative

    We studied the prevalence of fluconazole resistance in esophageal candidiasis. Patients with suspected esophageal candidiasis during gastroscopy underwent culture of white plaques. Minimum inhibitory concentration (MIC) >64 μg/mL of fluconazole for Candida was indicative of resistance. Sensitivity of itraconazole was tested in a subset of resistant strains. Sixty-five patients were included. Mean (SD) age was 50.03 (13.5) years and 67.7 % were males. Predisposing factors for candidiasis were found in 42 (64.6 %) patients. C. albicans was identified in 64 (97.4 %) patients and C. glabrata in one patient. Fluconazole resistance was seen in 38 (59.4 %) patients with C. albicans and also in the one patient with C. glabrata. All the fluconazole resistant isolates of C. albicans had MIC >128 μg/mL suggesting very high resistance. Twelve patients with fluconazole resistance had itraconazole resistance as well. The study shows a high rate of fluconazole resistance in patients with esophageal candidiasis.

    The widespread implementation of immunosuppressants, immunomodulators, hematopoietic stem cell transplantation and solid organ transplantation in clinical practice has led to an expanding population of patients who are at risk for invasive candidiasis, which is the most common form of fungal disease among hospitalized patients in the developed world. The emergence of drug-resistant Candida spp. has added to the morbidity associated with invasive candidiasis and novel therapeutic strategies are urgently needed. Areas covered: In this paper, we explore investigational agents for the treatment of invasive candidiasis, with particular attention paid to compounds that have recently entered phase I or phase II clinical trials. Expert opinion: The antifungal drug development pipeline has been severely limited due to regulatory hurdles and a systemic lack of investment in novel compounds. However, several promising drug development strategies have recently emerged, including chemical screens involving Pathogen Box compounds, combination antifungal therapy, and repurposing of existing agents that were initially developed to treat other conditions, all of which have the potential to redefine the treatment of invasive candidiasis.

    2012-01-01

    Uncomplicated vulvovaginal candidiasis appears in 75% women of reproductive age. The most frequent causes are Candida albicans (85-95%) or C. glabrata, and infrequently C. krusei, C. tropicalis, C. parapsilosis, C. pseudotropicalis, etc. The aim of the study was to investigate efficiency and safety of fenticonazole for vaginal candidiasis treatment. Therapeutic effect of a single 600 mg fenticonasole vaginal capsule was observed in 417 women, aged 16-67, in five centers in Serbia. In all women, before the treatment, vaginal candidiasis was confirmed by testing of vaginal smear. Based on smear findings and associated symptoms observed on the 7th and 28th day after therapy administration, treatment results were evaluated. On the next day after drug application the patients recorded by using a questionnaire their own feelings on withdrawal symptoms and possible side effects in the period prior to the first control. Control after seven days showed a statistically significant decrease of symptoms. In 385 women, vaginal smear was found negative to yeast and yeast blastospores. Within the first seven days after treatment 84 women had to repeat therapy due to the persistence of symptoms or positive vaginal smear. After 28 days we recorded full recovery in 392 patients, clinical improvement in eight, no change in 16, and deterioration in one patient only. Side effects were very seldom, mostly in the form of a slight redness of the vulva and vagina, and mild itching during several days. Our observations confirmed good efficacy and safety of fenticonazole in the treatment of vaginal candidiasis.

    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.

    Invasive Candida infections represent a diagnostic and therapeutic challenge for clinicians particularly in the intensive care unit (ICU). Despite substantial advances in antifungal agents and treatment strategies, invasive candidiasis remains associated with a high mortality. Recent guideline recommendations on the management of invasive candidiasis by the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) from 2012, the German Speaking Mycological Society and the Paul Ehrlich Society for Chemotherapy (DMykG/PEG) from 2011 and the Infectious Diseases Society of America (IDSA) from 2009 provide valuable guidance for diagnostic procedures and treatment of these infections but need to be interpreted in the light of the individual situation of the patient and the local epidemiology of fungal pathogens. The following recommendations for management of candidemia are common to all three guidelines. Any positive blood culture for Candida indicates disseminated infection or deep organ infection and requires antifungal therapy. Treatment should be initiated as soon as possible. Removal or changing of central venous catheters or other foreign material in the bloodstream is recommended whenever possible. Ophthalmological examination for exclusion of endophthalmitis and follow-up blood cultures during therapy are also recommended. Duration of therapy should be 14 days after clearance of blood cultures and resolution of symptoms. Consideration of surgical options and a prolonged antifungal treatment (weeks to months) are required when there is organ involvement. During the last decade several new antifungal agents were introduced into clinical practice. These innovative drugs showed convincing efficacy and favorable safety in randomized clinical trials. Consequently, they were integrated in recent therapeutic guidelines, often replacing former standard drugs as first-line options. Echinocandins have emerged as the generally preferred primary treatment in

    The Candida genus expresses virulence factors that, when combined with immunosuppression and other risk factors, can cause different manifestations of oral candidiasis. The treatment of mucosal infections caused by Candida and the elucidation of the disease process have proven challenging. Therefore, the study of experimentally induced oral candidiasis in rats and mice is useful to clarify the etiopathology of this condition, improve diagnosis, and search for new therapeutic options because the disease process in these animals is similar to that of human candidiasis lesions. Here, we describe and discuss new studies involving rat and mouse models of oral candidiasis with respect to methods for inducing experimental infection, methods for evaluating the development of experimental candidiasis, and new treatment strategies for oral candidiasis.

    Congenital candidiasis is a severe complication of candidal vulvovaginitis. It occurs in two forms,congenital mucocutaneous candidiasis and congenital systemic candidiasis. Also newborns are in age group the most vulnerable to invasive candidiasis. Congenital candidiasis should be considered as an interdisciplinary problem including maternal and fetal condition (including antibiotic therapy during pregnancy), birth age and rare genetic predispositions as severe combined immunodeficiency or neutrophil-specific granule deficiency. Environmental factors are no less important to investigate in diagnosing, treatment and prevention. External factors (e.g., food) and microenvironment of human organism (microflora of the mouth, intestine and genitalia) are important for solving clinical problems connected to congenital candidiasis. Physician knowledge about microorganisms in a specific compartments of the microenvironment of human organism and in the course of defined disorders of homeostasis makes it easier to predict the course of the disease and allows the development of procedures that can be extremely helpful in individualized diagnostic and therapeutic process.

    Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    Candida species have been implicated as significant contributors to morbidity in the neonatal period and are associated with 25-50% of mortality in invasive neonatal candidiasis. Peritoneal candidiasis, being paucisymptomatic, cannot often be correctly identified in a preterm neonate. The correct approach to diagnosis of neonatal peritoneal candidiasis is taking into account the epidemiology along with a strong clinical suspicion and appropriate timely diagnostic interventions. We report a case of fatal neonatal peritoneal candidiasis which was misdiagnosed as mucormycosis. © The Author [2016]. Published by Oxford University Press. All rights reserved.

    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.

    2014-12-01

    Full Text Available Vaginal candidiasis (VC is one of the most common reasons for consultations with a gynecologist, with an increasing trend in occurrence in female patients. It is estimated that 75% of all women experience an episode of vulvovaginal candidiasis in their lifetime, 50% of them experience at least a second episode, and 5% have recurrent candidiasis. Cervical and vaginal secretions act as the last line of defense from ascendant infection pathway spreading. Factors that may disturb vaginal ecosystem are: endogenous factors, way of life, infectious factors and iatrogenic factors. The most common cause of VC in 85-90% of cases is C. albicans, but other Candida species tend to be more likely to cause VVC (Candida tropicalis , Candida glabrata , C particulary, C crusei and so on. These non-albicans species have been found to be fluconazole and antimycotics resistant in more than 70% of cases. This is especially true for C. glabrata. There are several predisposing factors that have been associated with VC recurrence and resistance, such as Candida genotypes, resistance and virulence, immunodeficiency, unregulated hyperglycemia, use of oral contraceptives, long-term use of antibiotics. Therapy approach should be individual, including local and oral antimycotics until the symptoms disappear. The maintenance dose can be continuous or intermittent. Due to hormone concentration increase, increase in local glycogen, alternations of vaginal flora, VC incidence in pregnancy is two times higher in comparison to other female population. The problem of vaginal candidiasis requires individual approach, taking into account all the risk factors and accompanying physiological conditions or diseases in female patients.

    2012-01-01

    Oral candidiasis is an opportunistic infection caused by yeast of the Candida genus, primarily Candida albicans. It is generally associated with predisposing factors such as the use of immunosuppressive agents, antibiotics, prostheses, and xerostomia. The development of research in animal models is extremely important for understanding the nature of the fungal pathogenicity, host interactions, and treatment of oral mucosal Candida infections. Many oral candidiasis models in rats and mice have been developed with antibiotic administration, induction of xerostomia, treatment with immunosuppressive agents, or the use of germ-free animals, and all these models has both benefits and limitations. Over the past decade, invertebrate model hosts, including Galleria mellonella, Caenorhabditis elegans, and Drosophila melanogaster, have been used for the study of Candida pathogenesis. These invertebrate systems offer a number of advantages over mammalian vertebrate models, predominantly because they allow the study of strain collections without the ethical considerations associated with studies in mammals. Thus, the invertebrate models may be useful to understanding of pathogenicity of Candida isolates from the oral cavity, interactions of oral microorganisms, and study of new antifungal compounds for oral candidiasis.

    Pfaller, Michael A; Castanheira, Mariana

    2016-01-01

    Candidemia and other forms of candidiasis are associated with considerable excess mortality and costs. Despite the addition of several new antifungal agents with improved spectrum and potency, the frequency of Candida infection and associated mortality have not decreased in the past two decades. The lack of rapid and sensitive diagnostic tests has led to considerable overuse of antifungal agents resulting in increased costs, selection pressure for resistance, unnecessary drug toxicity, and adverse drug interactions. Both the lack of timely diagnostic tests and emergence of antifungal resistance pose considerable problems for antifungal stewardship. Whereas antifungal stewardship with a focus on nosocomial candidiasis should be able to improve the administration of antifungal therapy in terms of drug selection, proper dose and duration, source control and de-escalation therapy, an important parameter, timeliness of antifungal therapy, remains a victim of slow and insensitive diagnostic tests. Fortunately, new proteomic and molecular diagnostic tools are improving the time to species identification and detection. In this review we will describe the potential impact that rapid diagnostic testing and antifungal stewardship can have on the management of nosocomial candidiasis. © The Author 2015.

    Vaginal candidiasis is a common problem of clinical practice. Many studies have been conducted to explain its origin but only a few have included Polish women. The aim of the study was to determine the prevalence and similarity of oral, anal and vaginal Candida albicans strains isolated from Polish women with vaginal candidiasis. The study involved 20 from 37 recruited women. Swab samples were collected from their vagina, anus, and oral cavity at two-month intervals. All the women were treated with nystatin. Yeast were recovered and identified by the germ-tube test, API /Vitek system, typed by API ZYM and RAPD-PCR. Chi-square test was used to analyze the data. A total of 170 Candida albicans isolates were recovered from 180 samples collected 3 times from 3 sites of 20 women. Positive yeast vaginal cultures were found in all patients before administration of nystatin. Vaginal yeast recovery rate was decreased statistically significant in both follow-up visits (p= 0.001; p= 0.003). The same and different genotypes/biotypes were found concomitantly in a few body sites and/ or repeatedly at time interval from the same body site. The results support the concept of dynamic exchange of yeast within one woman and endogenous or exogenous origin of vaginal candidiasis.

    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 β-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

    Vulvovaginal candidiasis (VVC) and recurrent vulvovaginal candidiasis (RVVC) affect millions of women and are typically treated with azoles. We know little about azole susceptibility of Candida species from VVC versus RVVC patients, and nothing about African isolates. We have investigated the susceptibility of Candida isolates from Ghana to fluconazole, itraconazole and/or voriconazole. The percentage of Candida albicans isolates showing susceptibility was significantly lower in RVVC than VVC patients. Isolates of Candida parapsilosis and Candida tropicalis showed a similar trend. For Candida glabrata there was no observed difference. The data indicate a decreased susceptibility in selected Candida species from RVVC patients. © The Author 2016.

    To determine (1) the prevalence of candidal carriage in patients with oral mucosal disease to be treated with topical immunosuppressive therapy, and (2) the incidence of oral candidiasis among carriers and noncarriers after initiation of therapy to assess any correlation between carriage and the development of candidiasis. Records of patients who underwent swab cultures for Candida between January 2009 and October 2014 at the Brigham and Women's Hospital in Boston, Massachusetts, were retrospectively reviewed. The prevalence of candidal carriage and incidence of candidiasis were determined by using descriptive statistics. Of 99 evaluable patients, 20 (20.2%) were Candida positive and 79 (79.8%) were Candida negative. Of 44 patients with follow-up, 7 (15.9%) were Candida positive and 37 (84.1%) were Candida negative; five (11.4%) developed candidiasis. Four of seven (57.1%) Candida-positive patients developed candidiasis, whereas only one of 37 (2.7%) Candida-negative patients developed candidiasis (P = .0012). The overall prevalence of candidal carriage was low (20.2%), and there was a significant difference in the incidence of candidiasis between carriers and noncarriers (P = .0012) after topical immunosuppressive therapy. Therefore, patients who are candidal carriers should be monitored closely for the development of secondary candidiasis and may be candidates for prophylactic antifungal therapy.

    2009-01-01

    Background Risk factors for invasive candidiasis in children with candidemia are poorly defined. Methods We performed a retrospective cohort study of all children with candidemia at our tertiary children’s hospital from 2000 to 2006. Invasive candidiasis was diagnosed by review of the medical record and standardized EORTC/MSG criteria. A variety of risk factors for invasive candidiasis were explored. Results Of 194 episodes of candidemia in the microbiology laboratory database, 180 clinical records were available. Evaluation for invasive candidiasis consisted of 174 (97%) echocardiograms; 167 (93%) dilated ophthalmologic examinations, 136 (76%) chest CT scans, and 108 (60%) abdominal ultrasounds (complete, hepatosplenic or renal). Of the 180, 15 (8%) patients were identified with invasive candidiasis (4 proven, 1 probable, 10 possible). Prematurity candidiasis. Conclusions Invasive candidiasis, especially proven or probable, in the setting of candidemia was not common in our hospital, but premature infants and immunocompromised children were at significantly higher risk. Based on our findings, extensive imaging and examination by an ophthalmologist was particularly low-yield for invasive candidiasis in immunocompetent children beyond infancy. PMID:19821906

    This study compared the virulence of oral Candida species isolated from human immunodeficiency virus (HIV)-positive women with and without oral candidiasis. Candida species were isolated from 197 women, and their virulence attributes were measured. Of the 197 women, 117 (59.4%) carried Candida. Of these, 15 (12.8%) had symptoms of oral candidiasis. Among highly active antiretroviral therapy (HAART)-naive patients, 33% were diagnosed with oral candidiasis, whereas 5.9% were asymptomatic carriers (P oral candidiasis had higher levels of Candida (P = .02) than asymptomatic carriers. There was no difference in the CD4 counts and the virulence attributes of Candida from both the groups. This study indicates that oral candidiasis is mainly caused by high counts of C. albicans and suggests the importance of therapies targeting Candida counts in the oral cavity even in patients on HAART to reduce the development of infections.

    Background. Vulvovaginal candidiasis is characterized by curd-like vaginal discharge and itching, and is associated with considerable health and economic costs. Materials and Methods. We examined the incidence, prevalence, and risk factors for vulvovaginal candidiasis among a cohort of 898 women in south India. Participants completed three study visits over six months, comprised of a structured interview and a pelvic examination. Results. The positive predictive values for diagnosis of vulvovaginal candidiasis using individual signs or symptoms were low (candidiasis. Women clinically diagnosed with bacterial vaginosis had a higher prevalence of vulvovaginal candidiasis (Prevalence 12%, 95% CI 8.2, 15.8) compared to women assessed to be negative for bacterial vaginosis (Prevalence 6.5%, 95% 5.3, 7.6); however, differences in the prevalence of vulvovaginal candidiasis were not observed by the presence or absence of laboratory-confirmed bacterial vaginosis. Conclusions. For correct diagnosis of vulvovaginal candidiasis, laboratory confirmation of infection with Candida is necessary as well as assessment of whether the discharge has been caused by bacterial vaginosis. Studies are needed of women infected with Candida yeast species to determine the risk factors for yeast's overgrowth. PMID:23118494

    Full Text Available Duodenal white spots are mentioned in these nonspecific lesions until recently. Although there is not enough studies about duedonal white spots yet; these lesions described in a separate syndrome. Here now we reported a case that we diagnosed multiple Duodenal white spots mimicking intestinal candidiasis. Clinical manifestation and endoscopic appearance of lesions gave rise to thought intestinal candidiasis histopathological examination revealed us several duodenitis. There was no evidence of fungal infection in PAS staining. Early after endoscopy patient took treatment of Lansoprozole at the 30 mg dose and bismuth salicylate. Patients compliant declined and control endoscopy exposed white duodenal spots cleared away three months later. Duodenal white spots are becoming to be designated as a separate disease even a syndrome. Etiology of duodenal white spots must be determined carefully during endoscopy. Sometimes it is difficult to make the correct diagnosis by appearance of lesion; in such cases histopathological examination can be useful both differential diagnosis of disease and determination of etiological factor.

    Delayed initial antifungal therapy is associated with high mortality rates caused by invasive candida infections, since accurate detection of the opportunistic pathogenic yeast and its identification display a diagnostic challenge. diagnosis of candida infections relies on time-consuming methods such as blood cultures, serologic and histopathologic examination. to allow for fast detection and characterization of invasive candidiasis, there is a need to improve diagnostic tools. trends in diagnostics switch to non-culture-based methods, which allow specified diagnosis within significantly shorter periods of time in order to provide early and appropriate antifungal treatment. Areas covered: within this review comprise novel pathogen- and host-related testing methods, e.g. multiplex-PCR analyses, T2 magnetic resonance, fungus-specific DNA microarrays, microRNA characterization or analyses of IL-17 as biomarker for early detection of invasive candidiasis. Expert commentary: Early recognition and diagnosis of fungal infections is a key issue for improved patient management. As shown in this review, a broad range of novel molecular based tests for the detection and identification of Candida species is available. However, several assays are in-house assays and lack standardization, clinical validation as well as data on sensitivity and specificity. This underscores the need for the development of faster and more accurate diagnostic tests.

    Rabbits were employed as experimental models to evaluate a solid-phase radioimmunoassay (RIA) method for the diagnosis of systematic candidiasis. Ten rabbits were incubated subcutaneously to mimic superficial candidiasis and were found to produce no antibodies to Candida as determined by both immunodiffusion and RIA procedures. However, 94 per cent of 18 rabbits systematically infected by intravenous injection of Candida cells were observed to produce antibody as assessed by the RIA technique. These data encourage further tests with human sera and the continued development of this RIA procedure as a useful tool in the early serodiagnosis of systematic candidiasis. (Auth.)

    Vulvovaginal Candidiasis (VVC) is a common medical health problem of adult women. It is most commonly caused by Candida albicans . But there is a change in fungal profile. Sabouraud's Dextrose Agar (SDA) is the most common culture medium used where mixed fungal infection may be missed. It can be detected easily by using chromogenic culture medium. To know the fungal profile of vulvovaginal candidiasis using Candida CHROMagar and antifungal susceptibility pattern in patients attending tertiary care hospital. Culture confirmed cases of VVC presented at Department of Obstetrics and Gynaecology of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India, from July 2015 to December 2015 were included in the cross-sectional study. Two high vaginal swabs were collected and inoculated on SDA and Candida CHROMagar (Hi-Media, Mumbai, India). After overnight incubation the colonies were counted and colour of the colonies were recorded from Candida CHROMagar. Candida spp. were identified by sugar fermentation and assimilation tests and other conventional tests. Antifungal susceptibility tests were performed by the disc diffusion method using fluconazole (25 μg) and voriconazole (1μg) as per the Clinical and Laboratory Standards Institute (CLSI - M44-A2) guidelines. A total of 50 culture confirmed (23.7%) cases were detected from 211 clinically suspected VVC cases. Candida glabrata (45.1%) was the most common isolate, followed by Candida tropicalis (23.5%) , Candida albicans (17.6%) , Candida krusei (9.8%) and Candida parapsilosis (3.9%) . One mixed infection of C. glabrata and C. albicans was identified on Candida CHROMagar. Mixed fungal infection was observed in 2% of positive culture and 0.5% of VVC cases. The antifungal susceptibility testing revealed that 15.7% and 9.8% isolates of Candida spp. were resistant and Susceptible Dose Dependent (S-DD) respectively to fluconazole. The increase resistant against fluconazole was because of

    Our research on pathogenesis of disseminated candidiasis led to the discovery that antibodies specific for Candida albicans cell surface β-1, 2–mannotriose [β-(Man)3] protect mice. A 14 mer peptide Fba, which derived from the N-terminal portion of the C. albicans cytosolic/cell surface protein fructose-bisphosphate aldolase, was used as the glycan carrier and resulted in a novel synthetic glycopeptide vaccine β-(Man)3-Fba. By a dendritic cell-based immunization approach, this conjugate induced protective antibody responses against both the glycan and peptide parts of the vaccine. In this report, we modified the β-(Man)3-Fba conjugate by coupling it to tetanus toxoid (TT) in order to improve immunogenicity and allow for use of an adjuvant suitable for human use. By new immunization procedures entirely compatible with human use, the modified β-(Man)3-Fba-TT was administered either alone or as a mixture made with alum or monophosphoryl lipid A (MPL) adjuvants and given to mice by a subcutaneous (s.c.) route. Mice vaccinated with or, surprisingly, without adjuvant responded well by making robust antibody responses. The immunized groups showed a high degree of protection against a lethal challenge with C. albicans as evidenced by increased survival times and reduced kidney fungal burden as compared to control groups that received only adjuvant or DPBS buffer prior to challenge. To confirm that induced antibodies were protective, sera from mice immunized against the β-(Man)3-Fba-TT conjugate transferred protection against disseminated candidiasis to naïve mice, whereas C. albicans-absorbed immune sera did not. Similar antibody responses and protection induced by the β-(Man)3-Fba-TT vaccine was observed in inbred BALB/c and outbred Swiss Webster mice. We conclude that addition of TT to the glycopeptide conjugate results in a self-adjuvanting vaccine that promotes robust antibody responses without the need for additional adjuvant, which is novel and represents a

    The aim of this study was to evaluate the attitude of Jordanian dentists towards the treatment of oral candidiasis and their current antifungal prescribing habits, shedding more light on the possible influence of their socio-professional factors on the pattern of prescribing and practice. A structured validated questionnaire was developed and tested; it was then emailed to a random sample of 600 Jordanian dental practitioners during the period of this cross-sectional survey. The questionnaire recorded practitioners' personal details and their attitude and prescribing of antifungal therapy for oral candidiasis. Statistical significance was based on probability values of oral candidiasis. Of the 423 questionnaires returned, only 330 were included. The attitude of respondents was significantly influenced by their experience [odds ratio (OR) = 0.14; P oral candidiasis is much better among the least-experienced dentists working in private practice. Nystatin and miconazole are the most popular choices of antifungal agents among Jordanian dentists. © 2015 FDI World Dental Federation.

    Cerebral candidiasis is a devastating disease which contributes to a high mortality. Most of the cerebral candidiasis are never microbiologically or radiologically confirmed. In this case, a 4-year-old boy who developed cerebral candidiasis was successfully rescued and presented. The diagnosis of cerebral candidiasis was established based on both microbiologic and radiologic examinations. The pathogen was revealed to be Candida albicans by cerebrospinal fluid and central venous catheter cultures, and the cerebral involvement was recorded by series head magnetic resonance imaging (MRI) with an appearance of special encephalitis demonstrated. The imaging studies played a critical role throughout the diagnosis and treatment. Familiarity with the imaging findings in the appropriate clinical setting may result in a heightened level of awareness of this infection and, consequently, in earlier diagnosis and treatment. © The Author(s) 2014.

    2009-10-01

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

    The nuclear power generation industry is faced with public concern and government pressures over safety, efficiency and risk. Operators throughout the industry are addressing these issues with the aid of a new technology - technical document management systems (TDMS). Used for strategic and tactical advantage, the systems enable users to scan, archive, retrieve, store, edit, distribute worldwide and manage the huge volume of documentation (paper drawings, CAD data and film-based information) generated in building, maintaining and ensuring safety in the UK's power plants. The power generation industry has recognized that the management and modification of operation critical information is vital to the safety and efficiency of its power plants. Regulatory pressure from the Nuclear Installations Inspectorate (NII) to operate within strict safety margins or lose Site Licences has prompted the need for accurate, up-to-data documentation. A document capture and management retrieval system provides a powerful cost-effective solution, giving rapid access to documentation in a tightly controlled environment. The computerisation of documents and plans is discussed in this article. (Author)

    To investigate oral candidiasis in patients with head and neck cancer before, during, and after radiation therapy, and to explore its association with clinical oropharyngeal symptoms. A cohort study. University hospital. Subjects who received radiation therapy (RT) for the treatment of head and neck cancer were divided into two groups: an oral cavity irradiated group (OIRR group, n = 29) and an oral cavity nonirradiated group (ONIRR group, n = 17). A control group consisted of 18 healthy subjects. Patients were examined for signs of oral candidiasis before, during, immediately after, and one month after RT. Mouth and throat soreness (MTS), dysphagia, and xerostomia were evaluated by self-reported questionnaires, and associations between oral candidiasis and these symptoms were analyzed. The incidence of oral candidiasis during RT was significantly higher in the OIRR group (55.2%) than in the ONIRR group (11.8%). Similarly, the occurrence of xerostomia during RT was significantly higher in the OIRR group (86.2%) than in the ONIRR group (52.9%). In the OIRR group, the mean MTS score at the 20th fraction of RT was significantly higher in patients with candidiasis (mean +/- SD, 5.8 +/- 2.1) than in those with RT-induced mucositis without candidiasis (3.7 +/- 2.0). In the OIRR group, 65.2 percent of patients who experienced dysphagia developed oral candidiasis, compared with only 10 percent in the ONIRR group. Oral candidiasis concurrent with oral mucositis due to RT may increase oropharyngeal discomfort during RT. Copyright (c) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

    BACKGROUND: Oropharyngeal candidiasis (OPC) is a significant cause of morbidity, especially among patients with advanced cancer. The incidence and significance of yeast carriage and OPC in the palliative care setting in Denmark is unknown. The best diagnostic strategy and treatment regimen has...... positive and negative predictive value (∼50%). Candida albicans accounted for half of the isolates cultured. No C. albicans isolate displayed acquired fluconazole resistance; however, 3 out of 12 isolates of normally fluconazole-susceptible species were fluconazole resistant. These were all from patients...... recently treated with azoles. CONCLUSIONS: In total, 52% of culture-positive patients harbored at least one isolate with innately or acquired decreased fluconazole susceptibility. Therefore, susceptibility testing appears recommendable for patients with clinical signs of OPC....

    Recurrent vulvovaginal candidiasis (RVVC) has become very common. The aim of this study was to evaluate if women with RVVC perceive more signs of chronic stress than healthy control subjects. Thirty-three women with RVVC and 28 healthy control subjects completed a questionnaire about perceived stress at work and in private life, and a health questionnaire. A comparison of the results was performed with the one-way ANOVA test. More women with RVVC than control subjects reported signs of burnout (p stress (p balance between work and leisure time (p = 0.01), bodily symptoms of stress (p work (p stress in women with RVVC compared with healthy controls. These results are in line with our earlier findings of blunted morning rise cortisol and lower mean levels of cortisol in women with RVVC compared with healthy controls.

Such fungal localisations are not unfrequent, especially in immunodeficient patients (haematologic malignancies undergoing chemotherapy, lupus, serious visceral illness...). The positive diagnosis is uneasy because of non-specific clinical features and frequent negative blood cultures. Splenic localisation is the most likely. Citrate Gallium scintigraphy together with splenic labelled RBC scan enables us to give a precise view of the splenic involvment and even of the abdominal extension of the fungal abscess. From the literature review and these two cases, the excellent adequacy of the scintigraphy to the follow-up of systemic candidiasis is underlined and is compared to other usual morphological studies such as US scan and CT examination. In both cases, the diagnosis is fully confirmed by mycological examination [fr

    Systemic infection caused by Candida species is the fourth leading cause of nosocomial bloodstream infection in modern hospitals and carries high morbidity and mortality despite antifungal therapy. A recent surge of immunological studies in the mouse models of systemic candidiasis and the parallel discovery and phenotypic characterization of inherited genetic disorders in antifungal immune factors that are associated with enhanced susceptibility or resistance to the infection have provided new insights into the cellular and molecular basis of protective innate immune responses against Candida. In this review, the new developments in our understanding of how the mammalian immune system responds to systemic Candida challenge are synthesized and important future research directions are highlighted.

    Vulvovaginal candidiasis is an old disease that, even in a modern world, continues to have a high incidence. Despite the therapeutic advances, treatments are not always effective, and our understanding of the pathogenesis of this fungal infection is still incomplete. A discussion is presented in this article on the most significant developments related to the fungal virulence factors, the role of the immunological mechanisms involved in the vaginal protection, and the genetic alterations that confer susceptibility to the recurrent form of this mycosis. Current treatments, the use of new agents with antifungal activity, as well as the development of strategies, such as vaccination, are approached in the context of the complex scenario that governs the interactions between Candida and its host.

    Candida albicans is the predominant cause of vulvovaginal candidiasis (VVC). Little is known regarding the genetic diversity of Candida spp. in the vagina or the microvariations in strains over time that may contribute to the development of VVC. This study reports the draft genome sequences of four C. albicans and one C. glabrata strains isolated from women with VVC. An SNP-based whole-genome phylogeny indicates that these isolates are closely related; however, phylogenetic distances between them suggest that there may be genetic adaptations driven by unique host environments. These sequences will facilitate further comparative analyses and ultimately improve our understanding of genetic variation in isolates of Candida spp. that are associated with VVC. © FEMS 2017.

    Studies with an estrogen-dependent murine model of vaginal candidiasis suggest that local cell-mediated immunity (CMI) is more important than systemic CMI for protection against vaginitis. The present study, however, showed that, compared to uninfected mice, little to no change in the percentage or types of vaginal T cells occurred during a primary vaginal infection or during a secondary vaginal infection where partial protection was observed. Furthermore, depletion of polymorphonuclear leukocytes (PMN) had no effect on infection in the presence or absence of pseudoestrus. These results indicate a lack of demonstrable effects by systemic CMI or PMN against vaginitis and suggest that if local T cells are important, they are functioning without showing significant increases in numbers within the vaginal mucosa during infection.

    This study examined the association between oral candidiasis in elderly users and nonusers of prosthesis and its predisposing factors. To this end, we performed a cross-sectional study where saliva samples from 48 patients were collected they used prosthesis and 43 patients (control group) who did not use. Among the 91 patients, Candida spp were isolated in 40 (83.3%) who used prosthesis and in 23 (53.5%) in the control group. A statistically significant association was determined between the two groups, the isolation of yeasts and dental prosthesis (p oral candidiasis (n = 24), 83.3% (n = 20) belonged to the group that wore dentures, while only 16.7% (n = 4) belonged to the control group. Elderly patients with diabetes had 4.4 times higher estimated risk of developing oral candidiasis when compared with individuals without this condition. There was no statistically significant association between being user prostheses and have diabetes with the onset of candidiasis. No statistically significant association was determined between xerostomia, use of prosthesis and oral candidiasis. The use of prosthetics and poor oral hygiene in elderly patients predisposes to the development of oral candidiasis.

    Ozone is highly valued for various therapeutic applications such as antimicrobial, antihypoxic, analgesic, and immunostimulating for more than a century in the medical profession. Ozone therapy is now gaining a strong foothold in dentistry. Ozone has bactericidal, fungicidal, and virucidal properties. Oral candidiasis is one of the most common opportunistic fungal infections of the oral cavity. Hence, a study was conducted to evaluate and compare the ability of ozonated water and topical clotrimazole in reducing the Candidal species colony-forming unit (CFU) count in oral candidiasis. The study included 40 candidiasis patients of either sex aged between 18 and 60 years attending the Department of Oral Medicine and Radiology. The patients were randomly assigned to either topical ozone therapy or topical clotrimazole groups. Salivary Candidal CFU counts were assessed during and after the treatments. There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction) was more than the clotrimazole group (32.3% reduction). 14 patients (70%) with candidiasis in ozone group were reduced to 6 (30%) whereas only 8 patients (40%) out of 13 (65%) in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.

    Many of the molecular pathways associated with psoriasis pathogenesis are also involved in host defense mechanisms that protect against common pathogens. Candida can stimulate the production of cytokines that trigger or exacerbate psoriasis, and many systemic psoriasis treatments may put patients at increased risk for developing oral, cutaneous, and genitourinary candidiasis. Therefore, dermatologists should regularly screen patients with psoriasis for signs of Candida infection, and take steps to effectively treat these infections to prevent worsening of psoriasis symptoms. This review provides an overview of candidiasis epidemiology in patients with psoriasis, followed by a primer on the diagnosis and treatment of superficial Candida infections, with specific guidance for patients with psoriasis. Candidiasis in patients with psoriasis typically responds to topical or oral antifungal therapy. While biologic agents used to treat moderate-to-severe psoriasis, such as tumor necrosis factor-α inhibitors and interleukin-17 inhibitors, are known to increase patients' risk of developing localized candidiasis, the overall risk of infection is low, and candidiasis can be effectively managed in most patients while receiving systemic psoriasis therapies. Thus, the development of candidiasis does not usually necessitate changes to psoriasis treatment regimens.

    To determine the frequency of vaginal candidiasis in clinically symptomatic and asymptomatic cases of pregnant women attending routine antenatal clinic. A total of 110 pregnant women were nonrandomly recruited by convenient sampling. The studied variables included the demographic data information on parity, trimester of pregnancy, presence of vaginal discharge and the presence or absence of diabetes. Vulva and vagina were inspected for signs of inflammation and discharge with sterile speculum and vaginal specimens were collected with sterile cotton tipped swabs. Swabs were subjected to Gram staining and examined microscopically for the diagnosis of candidiasis. The frequency of vaginal candidiasis during pregnancy was found to be 38%, in which 27% were symptomatic and 11% were asymptomatic group. Increased ratio of infection was observed in multigravida and diabetic women. There was no marked differences in results with respect to age and trimester of pregnancy. Although there is generally a high frequency of vaginal candidiasis, an increased ratio of vaginal candidiasis in multigravida and diabetic pregnant women requires these women to be routinely screened for vaginal candidiasis regardless of symptomatic status.

    To investigate the relationship between vaginal and intestinal candida in patients with vulvovaginal candidiasis by using microbiological and molecular methods. The samples of vaginal discharge and anal swabs were collected from 148 cases with vulvovaginal candidiasis, followed by fungal culture, identification, purification and genome DNA extraction. The genome sequences from respective locations were aligned and typed according to their homology analyzed by internal transcribed spacer (ITS) PCR and random amplified polymorphic DNA (RAPD) PCR. Patients with vulvovaginal infection or those with infections in intestine and vulvovagina were pooled respectively, while the recurrent incidences after local anti-fungal treatments were analyzed. Candida albicans is the dominant pathogen in 148 cases with vulvovaginal candidiasis (91.9%, 136/148); 33.1% (49/148) of patients with vulvovaginal candidiasis were infected in both intestine and vulvovagina. While 92% (22/24) of patients with intestinal and vaginal candida infection showed high homology. The recurrent rate of patients with vulvovaginal candidiasis complicated with concurrent intestinal candida infection (7/14) was significantly higher than that of solo vaginal infected patients [21% (6/29)] after vaginal treatment (Pcandidiasis is highly associated with the concurrent infection of intestinal candida. The recurrent rate is high in patients with vulvovaginal candidiasis with concurrent infection of intestinal candida after vaginal treatment. The general management to those patients infected by both vulvovaginal and intestinal candida is necessary in reducing the recurrence of the disease.

    Treatment for oral candidiasis in warfarin users may be complicated by drug-drug interactions (DDIs) between warfarin and topically applied antimycotics. However, current knowledge of these putative DDIs is merely based on case series. We therefore performed a cohort cross-over study with the objective to evaluate the potential DDIs between warfarin and miconazole oral gel or nystatin oral solution. The cohort consisted of individuals using warfarin in the period of 1998-2012 (n ≈ 7400). We collected data on cohort members' measurements of the international normalized ratio (INR) from a clinical database, and obtained information on their use of topically applied miconazole and nystatin from a regional prescription register. Potential DDIs were assessed by comparing INR values before and after initiation of an antimycotic drug. Among 17 warfarin users exposed to miconazole oral gel, the mean INR increased from 2.5 (95% CI: 2.1-2.8) to 3.8 (95% CI: 2.8-4.8) after exposure, corresponding to a mean INR increase of 1.4 (95% CI: 0.3-2.4). Among 30 warfarin users exposed to nystatin oral solution, the mean INR was 2.7 (95% CI: 2.3-3.1) before and 2.5 (95% CI: 2.2-2.9) after exposure. In conclusion, we found evidence supporting a clinically relevant drug-drug interaction between warfarin and miconazole oral gel. In contrast, we did not find any indication of an interaction between warfarin and nystatin oral solution. Nystatin rather than miconazole should be preferred when treating warfarin users for oral candidiasis. © 2016 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

  5. Role for Dendritic Cells in Immunoregulation during Experimental Vaginal Candidiasis

    Vulvovaginal candidiasis (VVC) caused by the commensal organism Candida albicans remains a significant problem among women of childbearing age, with protection against and susceptibility to infection still poorly understood. While cell-mediated immunity by CD4+ Th1-type cells is protective against most forms of mucosal candidiasis, no protective role for adaptive immunity has been identified against VVC. This is postulated to be due to immunoregulation that prohibits a more profound Candida-specific CD4+ T-cell response against infection. The purpose of this study was to examine the role of dendritic cells (DCs) in the induction phase of the immune response as a means to understand the initiation of the immunoregulatory events. Immunostaining of DCs in sectioned murine lymph nodes draining the vagina revealed a profound cellular reorganization with DCs becoming concentrated in the T-cell zone throughout the course of experimental vaginal Candida infection consistent with cell-mediated immune responsiveness. However, analysis of draining lymph node DC subsets revealed a predominance of immunoregulation-associated CD11c+ B220+ plasmacytoid DCs (pDCs) under both uninfected and infected conditions. Staining of vaginal DCs showed the presence of both DEC-205+ and pDCs, with extension of dendrites into the vaginal lumen of infected mice in close contact with Candida. Flow cytometric analysis of draining lymph node DC costimulatory molecules and activation markers from infected mice indicated a lack of upregulation of major histocompatibility complex class II, CD80, CD86, and CD40 during infection, consistent with a tolerizing condition. Together, the results suggest that DCs are involved in the immunoregulatory events manifested during a vaginal Candida infection and potentially through the action of pDCs. PMID:16714548

    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. albicans vaginal infections. Thus, we have postulated that local immune mechanisms are critical for protection against infection. In the present study, the kinetic production of chemokines normally associated with the chemotaxis of T cells, macrophages (RANTES, MIP-1α, MCP-1), and polymorphonuclear neutrophils (MIP-2) was examined following intravaginal inoculation of C. albicans in estrogen-treated or untreated mice. Results showed significant increases in MCP-1 protein and mRNA in vaginal tissue of infected mice as early as 2 and 4 days postinoculation, respectively, that continued through a 21-day observation period, irrespective of estrogen status. No significant changes were observed with RANTES, MIP-1α, or MIP-2, although relatively high constitutive levels of RANTES mRNA and MIP-2 protein were observed. Furthermore, intravaginal immunoneutralization of MCP-1 with anti-MCP-1 antibodies resulted in a significant increase in vaginal fungal burden early during infection, suggesting that MCP-1 plays some role in reducing the fungal burden during vaginal infection. However, the lack of changes in leukocyte profiles in vaginal lavage fluids collected from infected versus uninfected mice suggests that MCP-1 functions to control vaginal C. albicans titers in a manner independent of cellular chemotactic activity.

  7. Effects of Reproductive Hormones on Experimental Vaginal Candidiasis

    Vulvovaginal candidiasis (VVC) is an opportunistic mucosal infection caused by Candida albicans that affects large numbers of otherwise healthy women of childbearing age. Acute episodes of VVC often occur during pregnancy and during the luteal phase of the menstrual cycle, when levels of progesterone and estrogen are elevated. Although estrogen-dependent experimental rodent models of C. albicans vaginal infection are used for many applications, the role of reproductive hormones and/or their limits in the acquisition of vaginal candidiasis remain unclear. This study examined the effects of estrogen and progesterone on several aspects of an experimental infection together with relative cell-mediated immune responses. Results showed that while decreasing estrogen concentrations eventually influenced infection-induced vaginal titers of C. albicans and rates of infection in inoculated animals, the experimental infection could not be achieved in mice treated with various concentrations of progesterone alone. Furthermore, progesterone had no effect on (i) the induction and persistence of the infection in the presence of estrogen, (ii) delayed-type hypersensitivity in primary-infected mice, or (iii) the partial protection from a secondary vaginal infection under pseudoestrus conditions. Other results with estrogen showed that a persistent infection could be established with a wide range of C. albicans inocula under supraphysiologic and near-physiologic (at estrus) concentrations of estrogen and that vaginal fungus titers or rates of infection were similar if pseudoestrus was initiated several days before or after inoculation. However, the pseudoestrus state had to be maintained for the infection to persist. Finally, estrogen was found to reduce the ability of vaginal epithelial cells to inhibit the growth of C. albicans. These results suggest that estrogen, but not progesterone, is an important factor in hormone-associated susceptibility to C. albicans vaginitis. PMID

    To evaluate the association between oral candidiasis and tuberculosis (TB) in human immunodeficiency virus (HIV) infected individuals in sub-Saharan Africa, and to investigate oral candidiasis as a potential tool for TB case finding. Protocol A5253 was a cross-sectional study designed to improve the diagnosis of pulmonary TB in HIV-infected adults in high TB prevalence countries. Participants received an oral examination to detect oral candidiasis. We estimated the association between TB disease and oral candidiasis using logistic regression, and sensitivity, specificity and predictive values. Of 454 participants with TB culture results enrolled in African sites, the median age was 33 years, 71% were female and the median CD4 count was 257 cells/mm(3). Fifty-four (12%) had TB disease; the prevalence of oral candidiasis was significantly higher among TB cases (35%) than among non-TB cases (16%, P oral candidiasis when controlling for CD4 count and antifungals (95%CI 1.2-4.7, P = 0.01). The sensitivity of oral candidiasis as a predictor of TB was 35% (95%CI 22-48) and the specificity 85% (95%CI 81-88). We found a strong association between oral candidiasis and TB disease, independent of CD4 count, suggesting that in resource-limited settings, oral candidiasis may provide clinical evidence for increased risk of TB and contribute to TB case finding.

    Data on safety and efficacy of voriconazole for invasive aspergillosis (IA) and invasive candidiasis/esophageal candidiasis (IC/EC) in pediatric patients are limited. Patients aged 2-<18 years with IA and IC/EC were enrolled in 2 prospective open-label, non-comparative studies of voriconazole. Patients followed dosing regimens based on age, weight and indication, with adjustments permitted. Treatment duration was 6-12 weeks for IA patients, ≥14 days after last positive Candida culture for IC patients and ≥7 days after signs/symptoms resolution for EC patients. Primary analysis for both the studies was safety and tolerability of voriconazole. Secondary end points included global response success at week 6 and end of treatment (EOT), all-causality mortality and time to death. Voriconazole exposure-response relationship was explored. Of 53 voriconazole-treated pediatric patients (31 IA; 22 IC/EC), 14 had proven/probable IA, 7 had confirmed IC and 10 had confirmed EC. Treatment-related hepatic and visual adverse events, respectively, were reported in 22.6% and 16.1% of IA patients, and 22.7% and 27.3% of IC/EC patients. All-causality mortality in IA patients was 14.3% at week 6; no deaths were attributed to voriconazole. No deaths were reported for IC/EC patients. Global response success rate was 64.3% (week 6 and EOT) in IA patients and 76.5% (EOT) in IC/EC patients. There was no association between voriconazole exposure and efficacy; however, a slight positive association between voriconazole exposure and hepatic adverse events was established. Safety and efficacy outcomes in pediatric patients with IA and IC/EC were consistent with previous findings in adult patients.

  10. Invasive Candidiasis in Various Patient Populations: Incorporating Non-Culture Diagnostic Tests into Rational Management Strategies

    Mortality rates due to invasive candidiasis remain unacceptably high, in part because the poor sensitivity and slow turn-around time of cultures delay the initiation of antifungal treatment. β-d-glucan (Fungitell) and polymerase chain reaction (PCR)-based (T2Candida) assays are FDA-approved adjuncts to cultures for diagnosing invasive candidiasis, but their clinical roles are unclear. We propose a Bayesian framework for interpreting non-culture test results and developing rational patient management strategies, which considers test performance and types of invasive candidiasis that are most common in various patient populations. β-d-glucan sensitivity/specificity for candidemia and intra-abdominal candidiasis is ~80%/80% and ~60%/75%, respectively. In settings with 1%–10% likelihood of candidemia, anticipated β-d-glucan positive and negative predictive values are ~4%–31% and ≥97%, respectively. Corresponding values in settings with 3%–30% likelihood of intra-abdominal candidiasis are ~7%–51% and ~78%–98%. β-d-glucan is predicted to be useful in guiding antifungal treatment for wide ranges of populations at-risk for candidemia (incidence ~5%–40%) or intra-abdominal candidiasis (~7%–20%). Validated PCR-based assays should broaden windows to include populations at lower-risk for candidemia (incidence ≥~2%) and higher-risk for intra-abdominal candidiasis (up to ~40%). In the management of individual patients, non-culture tests may also have value outside of these windows. The proposals we put forth are not definitive treatment guidelines, but rather represent starting points for clinical trial design and debate by the infectious diseases community. The principles presented here will be applicable to other assays as they enter the clinic, and to existing assays as more data become available from different populations. PMID:29376927

    Photodynamic therapy (PDT) has been used in recent years to deal with fungal infections because of the prevalence of fungi resistance to drugs. However, PDT for gastrointestinal fungal infection has not been reported. This study was conducted to assess the potential of PDT to deal with esophageal candidiasis. Two male patients with histological evidence of esophageal candidiasis coexisting with esophageal cancer were included in this retrospective study. Both patients were treated with PDT. This treatment was repeated at least 1month after the initial PDT if the patient still had residual cancer or esophageal candidiasis. Short-term efficacy was evaluated on the basis of endoscopy and histology findings. Further follow-up data were obtained from endoscopy results or telephone conversation. The esophageal candidiasis located 21-24cm and 25-28cm from the incisors of case 1 reached complete remission after one and two PDT sessions, respectively. The esophageal cancer coexisting with esophageal candidiasis located 21-24cm from the incisors reached complete remission after two PDT sessions. No recurrence was found at a 14-month follow-up. The esophageal cancer located 30-35cm from the incisors reached partial response after three PDT sessions. Both of the esophageal candidiasis and the coexisting esophageal cancer at 23-26cm from the incisors of case 2 reached complete remission and the esophageal cancer at 34-37cm from the incisors reached complete remission after one PDT session. No recurrence was found at a 24-month follow-up. There were no serious adverse events found in either of the two cases. Results of this preliminary study indicate that PDT may be a potential method to deal with esophageal candidiasis. Copyright © 2013 Elsevier B.V. All rights reserved.

  12. Invasive Candidiasis in Various Patient Populations: Incorporating Non-Culture Diagnostic Tests into Rational Management Strategies

    Full Text Available Mortality rates due to invasive candidiasis remain unacceptably high, in part because the poor sensitivity and slow turn-around time of cultures delay the initiation of antifungal treatment. β-d-glucan (Fungitell and polymerase chain reaction (PCR-based (T2Candida assays are FDA-approved adjuncts to cultures for diagnosing invasive candidiasis, but their clinical roles are unclear. We propose a Bayesian framework for interpreting non-culture test results and developing rational patient management strategies, which considers test performance and types of invasive candidiasis that are most common in various patient populations. β-d-glucan sensitivity/specificity for candidemia and intra-abdominal candidiasis is ~80%/80% and ~60%/75%, respectively. In settings with 1%–10% likelihood of candidemia, anticipated β-d-glucan positive and negative predictive values are ~4%–31% and ≥97%, respectively. Corresponding values in settings with 3%–30% likelihood of intra-abdominal candidiasis are ~7%–51% and ~78%–98%. β-d-glucan is predicted to be useful in guiding antifungal treatment for wide ranges of populations at-risk for candidemia (incidence ~5%–40% or intra-abdominal candidiasis (~7%–20%. Validated PCR-based assays should broaden windows to include populations at lower-risk for candidemia (incidence ≥~2% and higher-risk for intra-abdominal candidiasis (up to ~40%. In the management of individual patients, non-culture tests may also have value outside of these windows. The proposals we put forth are not definitive treatment guidelines, but rather represent starting points for clinical trial design and debate by the infectious diseases community. The principles presented here will be applicable to other assays as they enter the clinic, and to existing assays as more data become available from different populations.

    Oral candidiasis (OC) is a potential oral complication in Sjögren's syndrome (SS). Some studies indicate that the low stimulated salivary flow and not low unstimulated salivary flow is associated with OC in SS, while others report that the underlying autoimmune disorders contribute to OC, based solely on correlation coefficients. Given the conflicting and limited existing evidence, we purposed to ascertain the role of both salivary gland dysfunction (hyposalivation based on unstimulated and stimulated flow rates) and autoimmunity (SS, other autoimmune disorders) in OC among those with SS, other salivary gland dysfunction, and non-salivary gland dysfunction controls (NSGD). A nested case-control study was designed within a larger NIH/NIDCR cohort. Descriptive analyses, nonparametric tests, comparative analyses, and multivariate logistic regression analyses were undertaken. Data on 1526 subjects (701 SS, 247 ISS, 355 Sicca, and 223 NSGD) were obtained from the source cohort of 2046 and analyzed for this study. The median whole unstimulated salivary flow rate (WUS, ml 15 min -1 ) was lower in SS (0.8, interquartile range (IQR) 1.8) compared to ISS (5.5, IQR: 5.2, P salivary flow rate (TSS, ml 15 min -1 ) was lowest in SS (7.0, IQR: 12.4, P diabetes mellitus (4.2, 95%CI: 1.2-15.2, P = 0.02) were independent predictors of OC; females had a lower risk than males (OR = 0.29, 95%CI: 0.13-0.67, P = 0.004). Age, race, anti-SSA/SSB autoantibodies, focus score, other medications, anxiety, fatigue, cigarette smoking, alcohol, and caffeine use were not associated with oral candidiasis. Salivary gland dysfunction (hyposalivation with WUS being a stronger predictor than TSS) and autoimmunity (SS, other autoimmune disorders, medications, i.e., DMARDS) are both independent predictors of OC. Diabetes mellitus is an independent predictor of OC among those with salivary gland dysfunction. Our findings suggest that these independent predictors should be considered in the

    Full Text Available In this paper, the concept of locally simple models is considered. Locally simple models are arbitrarily complex models built from relatively simple components. A lot of practically important domains of discourse can be described as locally simple models, for example, business models of enterprises and companies. Up to now, research in human reasoning automation has been mainly concentrated around the most intellectually intensive activities, such as automated theorem proving. On the other hand, the retailer business model is formed from ”jobs”, and each ”job” can be modelled and automated more or less easily. At the same time, the whole retailer model as an integrated system is extremely complex. In this paper, we offer a variant of the mathematical definition of a locally simple model. This definition is intended for modelling a wide range of domains. Therefore, we also must take into account the perceptual and psychological issues. Logic is elitist, and if we want to attract to our models as many people as possible, we need to hide this elitism behind some metaphor, to which ’ordinary’ people are accustomed. As such a metaphor, we use the concept of a document, so our locally simple models are called document models. Document models are built in the paradigm of semantic programming. This allows us to achieve another important goal - to make the documentary models executable. Executable models are models that can act as practical information systems in the described domain of discourse. Thus, if our model is executable, then programming becomes redundant. The direct use of a model, instead of its programming coding, brings important advantages, for example, a drastic cost reduction for development and maintenance. Moreover, since the model is well and sound, and not dissolved within programming modules, we can directly apply AI tools, in particular, machine learning. This significantly expands the possibilities for automation and

    Roles of aging or immune responses mediated by Toll-like receptors and natural killer cell in the onset or progression of human candidiasis remain unclear. This study was designed to elucidate the roles using peripheral blood mononuclear cells from healthy donors and patients with oral candidiasis. Subjects tested were healthy volunteers and patients who visited Dental Clinical Division of Hokkaido University Hospital. The patients with oral candidiasis included 39 individuals (25-89 years of age) with major complaints on pain in oral mucosa and/or dysgeusia. Healthy volunteers include students (25-35 years of age) and teaching staffs (50-65 years of age) of Hokkaido University Graduate School of Dental Medicine. Functions of Toll-like receptors 2 and 4 were downregulated significantly and the natural killer activity was slightly, but not significantly downregulated in aged healthy volunteers compared with healthy young volunteers. Functions of Toll-like receptors 2 and 4 and the natural killer activity were significantly downregulated in patients with oral candidiasis compared with healthy volunteers. Downregulation of functions of Toll-like receptors 2 and 4 as well as natural killer activity is suggested to be associated with the onset or progression of oral candidiasis in human. © 2015 John Wiley & Sons A/S.

    One of the most common fungal infections infecting humans is Candidiasis. Belonging to the group of opportunistic infections, it often affects individuals with various debilitating diseases. Fluconazole and clotrimazole are two of the commonly used anti-fungal agents for the treatment of oral candidiasis. Hence, we planned this study to evaluate the effectiveness of fluconazole and clotrimazole in the treatment of patients suffering from candidiasis. A total of 180 participants were enrolled in the present study. All the patients of candidiasis were divided broadly into two study groups. Group I included patients who were treated with fluconazole mouthrinse whereas group II included patients who were treated with clotrimazole mouth paint. Grading of patient discomfort was done as noted from readings given by the patients. Specimen was collection by a swab from the lesional area of the oral cavity from the patients and were incubated in Sabouraud's dextrose agar medium and assessed. All the patients were treated with medication as give to their respective groups. Patients were recalled as assessed. All the readings were recorded and analyzed. For group I patients, the fungal eradication was 89.5%, whereas for group II patients, the fungal eradication was 86.7%. No significant results were obtained while comparing the mycological eradiation in patients of the two study groups. Approximately similar effectiveness in terms of treatment was noted with fluconazole and clotrimazole in treating patients with candidiasis.

    Vulvovaginal candidiasis is the second most common cause of vaginitis worldwide (after bacterial candidiasis). Maternal vulvovaginal candidiasis is a major risk factor for Candida colonization and infection of the infant where prognosis depends on different predisposing factors. The aim of this study was to determine the incidence and the etiological structure of vulvovaginal candidiasis in pregnant women and its impact on Candida colonization of newborns. Samples of vaginal secretions from 80 healthy pregnant women who were clinically suspicious for Candida vaginitis were collected within 48 hours before delivery. Samples for probable Candida colonization from the oral mucosa and feces were collected from their newborns within 47-72 hours after birth. Samples were plated on Sabouraud agar, followed by species identification by API Candida yeast assay. Twenty-three (28.75 ± 5.06%) of the evaluated pregnant women were positive for Candida spp. Positive samples for Candida colonization were found in 18 (22.22 ± 4.62%) of the examined 81 newborns (one pair of twins) from mothers who were clinically suspicious for vaginal candidiasis. Isolates of the newborns were 100% identical to those of the mothers' vaginal secretion. Candida albicans was the predominant species identified in the pregnant women (91.67 ± 0.06%) and in the neonates (83.33±8.78%).

    The purpose of this study was to determine the characteristics of HIV/AIDS patients with oral candidiasis as its clinical manifestation at Airlangga University Hospital Surabaya. This is a descriptive analytic research with cross-sectional design using Chi-Square statistic test. Samples of this study consist of 34 patients using total sampling methods. Those patients were all HIV/AIDS infected patients with oral candidiasis clinical manifestations, who were admitted to Airlangga University Hospital Surabaya from January 2016 to September 2017. Results showed that mostly HIV/AIDS patients with oral candidiasis are male (79.4%), old age (40-75years) total amounted to 58.8%, heterosexual as main risk factor (70%), clinical stadium mostly in stage IV (61.8%), 26% of patients with chronic diarrhea and 56% with pulmonary TB, clinical stages of patients have a significant relation to the incidence of oral candidiasis infection (p=0.024). The most common oral lesions found in people with HIV are Candidiasis. The best management is through routine dental examination and dental precautions to maintain health and achieve a better quality of life.

    Invasive candidiasis is the 4th leading cause of nosocomial bloodstream infection in the US with mortality that exceeds 40% despite administration of antifungal therapy; neutropenia is a major risk factor for poor outcome after invasive candidiasis. In a fatal mouse model of invasive candidiasis that mimics human bloodstream-derived invasive candidiasis, the most highly infected organ is the kidney and neutrophils are the major cellular mediators of host defense; however, factors regulating neutrophil recruitment have not been previously defined. Here we show that mice lacking chemokine receptor Ccr1, which is widely expressed on leukocytes, had selectively impaired accumulation of neutrophils in the kidney limited to the late phase of the time course of the model; surprisingly, this was associated with improved renal function and survival without affecting tissue fungal burden. Consistent with this, neutrophils from wild-type mice in blood and kidney switched from Ccr1lo to Ccr1high at late time-points post-infection, when Ccr1 ligands were produced at high levels in the kidney and were chemotactic for kidney neutrophils ex vivo. Further, when a 1∶1 mixture of Ccr1+/+ and Ccr1−/− donor neutrophils was adoptively transferred intravenously into Candida-infected Ccr1+/+ recipient mice, neutrophil trafficking into the kidney was significantly skewed toward Ccr1+/+ cells. Thus, neutrophil Ccr1 amplifies late renal immunopathology and increases mortality in invasive candidiasis by mediating excessive recruitment of neutrophils from the blood to the target organ.

    Full Text Available AIM: Candidiasis is the leading opportunistic mycosis in HIV and AIDS patients. METHOD: In order to determine its prevalence in patients with different CD4+ T cell categories in the Nylon Health District in Douala, a cross-sectional study was carried out whereby 304 HIV positive individuals were recruited between March and August, 2007. They were divided into two groups; those on highly active antiretroviral therapy (HAART and those not on HAART. Three samples constituting mouth, vaginal/urethral swabs and urine were collected from each subject. RESULTS: A total of 204 (67.1% [95% confidence interval (CI: 0.618-0.724] of these patients had more than one predisposing condition to candidiasis, with those on antibiotic therapy having the highest prevalence (63.7% followed by pregnant patients (7.3% (P < 0.05. Candidiasis was more common in patients with low CD4+ T cell count (<200 [66%] than patients with higher CD4+ T cell count (17.9% (P<0.05. One hundred and sixty one (53% of the patients had candidiasis whereby those not on HAART were more frequently infected (69.6% than those on HAART (30.1% (P< 0.05. CONCLUSION: We conclude that candidiasis is a major opportunistic infection in HIV patients and should be checked especially in patients not yet on antiretroviral therapy.

    1994-01-01

    Full Text Available It is estimated that 75% of all women will experience at least 1 episode of vulvovaginal candidiasis (VVC during their lifetimes. Most patients with acute VVC can be treated with short-term regimens that optimize compliance. Since current topical and oral antifungals have shown comparably high efficacy rates, other issues should be considered in determining the most appropriate therapy. It is possible that the use of short-duration narrow-spectrum agents may increase selection of more resistant organisms which will result in an increase of recurrent VVC (RVVC. Women who are known or suspected to be pregnant and women of childbearing age who are not using a reliable means of contraception should receive topical therapy, as should those who are breast-feeding or receiving drugs that can interact with an oral azole and those who have previously experienced adverse effects during azole therapy. Because of the potential risks associated with systemic treatment, topical therapy with a broad-spectrum agent should be the method of choice for VVC, whereas systemic therapy should be reserved for either RVVC or cases where the benefits outweigh any possible adverse reactions.

    1983-10-01

    In 32 patients (11 females, 21 males) the diagnosis of chronic oral multifocal candidiasis was established on the basis of erythematous, plaquelike, or nodular lesions in two or more of the following locations: commissural area, palate, or dorsum of the tongue. Hyphae and/or pseudohyphae of Candida-like organisms were demonstrated in PAS-stained smears from all lesions. Ninety-seven separate lesions were registered. Thirty patients experienced pain, burning, or itching from affected areas. All of the patients were tobacco smokers, and 21 were denture wearers. The patients were treated with antimycotics; the median length of treatment was 46 days for denture wearers and 44 days for nondenture wearers. After antimycotic therapy the change in the lesions followed certain patterns which were determined by the original type of lesion. Palatal lesions in nondenture wearers and nodular lesions of the commissural areas showed the highest recurrence rate after 6 and 12 months. The pathogenic role of tobacco and other factors in the development of candidal infection are discussed.

    Vulvovaginal candidiasis (VVC) is an insidious infection that afflicts a large proportion of women of all ages, and 5 to 8% of affected women experience recurrent VVC (RVVC). The aim of this study was to explore the possible importance of vaginal bacterial communities in reducing the risk of RVVC. The species composition and diversity of microbial communities were evaluated for 42 women with and without frequent VVC based on profiles of terminal restriction fragment polymorphisms of 16S rRNA genes and phylogenetic analysis of cloned 16S rRNA gene sequences from the numerically dominant microbial populations. The data showed that there were no significant differences between the vaginal microbial communities of women in the two groups (likelihood score, 5.948; bootstrap P value, 0.26). Moreover, no novel bacteria were found in the communities of women with frequent VVC. The vaginal communities of most women in both groups (38/42; 90%) were dominated by species of Lactobacillus. The results of this study failed to provide evidence for the existence of altered or unusual vaginal bacterial communities in women who have frequent VVC compared to women who do not have frequent VVC. The findings suggest that commensal vaginal bacterial species may not be able to prevent VVC.

    We evaluated whether vaginal concentrations of hyaluronan were altered in women with recurrent vulvovaginal candidiasis (RVVC). Lavage samples from 17 women with acute RVVC, 27 women who were receiving a maintenance antifungal regimen, and 24 control women were tested for hyaluronan and interleukin (IL)-6, IL-12, and IL-23 by enzyme-linked immunosorbent assay. Median vaginal hyaluronan concentrations were 33.8 ng/mL (range, 21.6-66.3 ng/mL) in women with acute RVVC, 15.0 ng/mL (range, 11.2-50.6 ng/mL) in women who were receiving maintenance therapy, and 4.2 ng/mL (range, 3.6-12.0 ng/mL) in control subjects (P vaginal hyaluronan concentration was 27.4 ng/mL (range, 15.4-37.7 ng/mL) when Candida was detected by microscopy and 9.5 ng/mL (range, 7.7-14.6 ng/mL) in microscopy-negative cases (P = .0354). Elevated hyaluronan levels were associated with itching plus burning (40.7 ng/mL) or itching plus discharge (42.1 ng/mL), as opposed to itching only (6.2 ng/mL; P = .0152). Hyaluronan and IL-6 levels were correlated (P = .0009). Hyaluronan release is a component of the host response to a candidal infection and may contribute to symptoms.

The Association of Medical Microbiology and Infectious Disease Canada developed evidence-based guidelines for the approach to the diagnosis and management of these infections in the ever-increasing population of at-risk adult patients in the health care system. Over the past few years, a new and broader understanding of the epidemiology and pathogenesis of C/IC has emerged and has been coupled with the availability of new antifungal agents and defined strategies for targeting groups at risk including, but not limited to, acute leukemia patients, hematopoietic stem cell transplants and solid organ transplants, and critical care unit patients. Accordingly, these guidelines have focused on patients at risk for C/IC, and on approaches of prevention, early therapy for suspected but unproven infection, and targeted therapy for probable and proven infection.

    The article reviews some commonly used orthodontic treatments as well as new strategies to assist in the correction of malocclusion. Many techniques are used in conjunction with surgical intervention and are a necessary compliment to orthognathic surgery. Basic knowledge of these practices will aid in the surgeon's ability to adequately treat the patient. Many orthodontists and surgeons are eliminating presurgical orthodontics to adopt a strategy of 'surgery first' orthodontics in orthognathic surgery. This has the benefit of immediate improvement in facial aesthetics and shorter treatment times. The advent of virtual surgical planning has helped facilitate the development of this new paradigm by making surgical planning faster and easier. Furthermore, using intraoperative surgical navigation is improving overall precision and outcomes. A variety of surgical and nonsurgical treatments may be employed in the treatment of malocclusion. It is important to be familiar with all options available and tailor the patient's treatment plan accordingly. Surgery-first orthodontics, intraoperative surgical navigation, virtual surgical planning, and 3D printing are evolving new techniques that are producing shorter treatment times and subsequently improving patient satisfaction without sacrificing long-term stability.

    Oral candidiasis is one of the most common opportunistic fungal infections of the oral cavity in human. Among children, this condition represents one of the most frequent affecting the mucosa. Although most diagnoses are made based on clinical signs and features, a microbiological analysis is sometimes necessary. We performed a literature review on the diagnosis of oral candidiasis to identify the techniques most commonly employed in routine clinical practice. A Medline-PubMed search covering the last 10 years was performed. Microbiological techniques were used in cases requiring confirmation of the clinical diagnosis. In such cases, direct microscopy was the method most commonly used for diagnosing candidiasis. Direct microscopy appears as the method of choice for confirming clinical diagnosis and could become a routine chair-side technique.

    A daily eatable candy that has possible protective activity against oral candidiasis was experimentally produced. The candy was made from reduced-maltose as main constituent and from several natural products, such as oligonol (depolymerized polyphenols derived from lychee), cinnamon (cassia), citral, and capric acid, which are known to have anti-Candida activity in vitro and in vivo. The candy effectively inhibited the mycelial growth of C. albicans, even when it was diluted 1,000 times with culture media. We assessed the protective activity of the candy against murine candidiasis. When 50μl of candy dissolved and diluted 4 times with water was administered 3 times into the oral cavity of Candida infected mice, the score of lesions on the Candida-infected tongues improved on day 2. These findings suggest that this candy has potential as food that provides protective activity against oral candidiasis.

    BACKGROUND Graft-site candidiasis rarely develops in solid organ transplant recipients; however, severe life-threatening complications can occur. We report the course of 3 solid organ transplant recipients developing graft-site candidiasis. CASE REPORT All grafts, consisting of 2 kidneys and 1 liver, were procured from a single donor. Patient data were collected from our database. Candida albicans was isolated from a swab taken during multiple-organ recovery. Complications associated with candidiasis occurred in all 3 recipients with preservation of the liver transplant. Both renal transplant recipients had vascular complications, eventually resulting in graft nephrectomy and subsequent return to dialysis. The patients recovered completely without residual effects of their prior fungal infection. CONCLUSIONS Fungal infections in solid organ transplant recipients are rare. Since the sequelae of these infections are serious and usually pertain to more than 1 recipient at a time, antifungal prophylaxis may be warranted in select donors.

    To investigate the expression of vaginal IL-23 and its role in experimental murine vaginal candidiasis and its relationship with infection and immune status, immuno-competent (group A) and immuno-suppressed (group B) murine models of vaginal candidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls (group C). The level of IL-23 p19 mRNA in murine vaginal tissue was determined by RT-PCR. Significantly increased levels of IL-23p19mRNA were observed on the 4th, the 7th and 14th day after inoculation in immuno-competent group when compared with that in control group (Pvaginal candidiasis and has a protective function during infection. Low vaginal IL-23 level may correlate with the increased susceptibility to Candida albicans in immuno-suppressed group.

    Vulvovaginal candidiasis is one of the most common infections of the genital tract in women that causes many complications. Therefore, we examined the clinical effect of ginger cream along with clotrimazole compared to vaginal clotrimazole alone in this study. This double-blind clinical trial was conducted on 67 women admitted to the Gynecology Clinic of Hajar Hospital with vaginal candidiasis. The patients were divided randomly into two groups of 33 and 34 people. The diagnosis was made according to clinical symptoms, wet smear, and culture. Ginger-clotrimazole vaginal cream 1% and clotrimazole vaginal cream 1% were administered to groups 1 and 2, respectively, once a day for 7 days and therapeutic effects and symptoms were evaluated in readmission. Data analysis was performed using SPSS version 22, t -test and Chi-square. The mean value of variables itching ( P > 0.05), burning ( P > 0.05), and cheesy secretion ( P vaginal candidiasis.

    Full Text Available Hepatosplenic candidiasis also known as chronic disseminated candidiasis is a rare manifestation of invasive fungal infection typically observed in patients with acute leukemia in prolonged, deep neutropenia. Immune reconstitution inflammatory syndrome (IRIS is an inflammatory disorder triggered by rapid resolution of neutropenia. Diagnosis and treatment of IRIS are still challenging due to a variety of clinical symptoms, lack of certain diagnostic criteria, and no standards of treatment. The diagnosis of IRIS is even more difficult in patients with hematological malignancies complicated by “probable” invasive fungal infection, when fungal pathogen is still uncertain. We report a case of probable hepatic candidiasis in 4-year-old boy with acute lymphoblastic leukemia. Despite proper antifungal therapy, there was no clinical and radiological improvement, so diagnosis of Candida-related IRIS was made and corticosteroid therapy was added to antifungal treatment achieving prompt resolution of infection symptoms.

    Abdominal CT performed in 14 leukemic patients with systemic candidiasis and involvement of the liver, spleen, or kidneys revealed numerous low-density lesions in ten livers (71%), eight spleens (57%), and in the kidneys of three patients (21%). Biopsy of all livers and of three kidneys proved hepatic candidiasis in all (100%) and renal candidiasis in three patients (21%). After treatment with amphotericin B and splenectomy (one patient), CT disclosed abnormal livers in eleven (80%) patients, abnormal spleens in seven (53%), and abnormal kidneys in three patients (21%). Rebiopsy disclosed Candida infection in all livers and all abnormal kidneys, so the patients were treated with liposomal amphotericin B. Although the patients became asymptomatic, CT continued to show abnormal livers in five (35%) and abnormal spleens in two (16%) (the previously abnormal kidneys became normal). Rebiopsy of the abnormal livers showed focal fibrosis and necrosis. These findings emphasize the importance of clinical and pathologic correlation of CT appearance

    Infections are known to trigger and exacerbate psoriasis. Although oral candidiasis is often clinically diagnosed, it is not always confirmed by laboratory tests such as oral cytopathology. The aims of this study were to determine the prevalence of oral candidiasis in patients with psoriasis through clinical and cytopathological diagnosis and to investigate the association between oral candidiasis and psoriasis with regards to the severity of the clinical presentation and the type of treatment for psoriasis. A total of 140 patients with psoriasis and 140 healthy control subjects received an oral examination. Scrapings of the tongue were also obtained for a cytopathological examination. The oral examination and the results of the cytopathological smear revealed 37 (26%) cases of candidiasis in the patients with psoriasis and no cases of candidiasis in the healthy control subjects. There was no correlation between the type of psoriasis treatment and the presence of oral candidiasis (P = .616). There was a statistically significant association (P = .033) between the clinical severity of psoriasis and the presence of Candida. This study was limited by the small number of subjects and the lack of follow-up to determine the development of psoriasis after treatment for oral candidiasis. The presence of oral candidiasis is higher in patients with psoriasis and it is associated with disease severity. This increased presence of oral candidiasis was apparent despite any type of treatment for the psoriasis. Cytopathology to rule out oral candidiasis should be used in the routine medical workup of patients with psoriasis. Copyright © 2012 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    1987-01-01

    Full Text Available Total and candida specific serum IgE levels were studied in 21 patients who fulfilled the criteria for recurrent vaginal candidiasis, and 45 controls. The candida specific IgE levels were significantly higher in patients with recurrent vaginal candidiasis when compared with the controls. There was no significant difference in the total IgE levels between patients and the controls. IgE is postulated to inhibit the cellular immune respsnse to candida and thereby prevent its eradication. There may be a genetic basis for the increased IgE levels.

    Results. Sixty-three newborns with invasive neonatal candidiasis were identified. Overall mortality rate was 35%. Virtually every infant had a central venous catheter (CVC, required mechanical ventilation and previous administration of antibacterial agents. Delayed institution of antifungal therapy was associated with increased mortality. In addition, length of hospitalization, duration of prior antibacterial therapy, mechanical ventilation, and CVC use, as well as evidence of end-organ disease, were associated with an adverse outcome. Conclusions. Reliance on available laboratory tools in cases of invasive neonatal candidiasis can result in delayed diagnosis and increased mortality. A risk-factor-based approach to empirical treatment could be justified in this setting.

    Vulvovaginal candidiasis (VVC) is estimated to be the second most common form of infection after bacterial vaginosis. The ability of probiotics in maintaining and recovering the normal vaginal microbiota, and their potential ability to resist Candidas give rise to the concept of using probiotics for the treatment of VVC. To assess the effectiveness and safety of probiotics for the treatment of vulvovaginal candidiasis in non-pregnant women. We searched the following databases to October 2017: Sexually Transmitted Infections Cochrane Review Group's Specialized Register, CENTRAL, MEDLINE, Embase and eight other databases. We searched in following international resources: World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, Web of Science and OpenGrey. We checked specialty journals, reference lists of published articles and conference proceedings. We collected information from pharmaceutical companies and experts in the field. Randomized controlled trials (RCT) using probiotics, alone or as adjuvants to conventional antifungal drugs, to treat VVC in non-pregnant women. Trials recruiting women with recurrent VVC, coinfection with other vulvovaginal infections, diabetes mellitus, immunosuppressive disorders or taking immunosuppressant medication were ineligible for inclusion. Probiotics were included if they were made from single or multiple species and in any preparation type/dosage/route of administration. Two review authors independently assessed trials for eligibility and quality and extracted data. We resolved any disagreements through consensus. The quality of the evidence was assessed using the GRADE approach. Ten RCTs (1656 participants) met our inclusion criteria, and pharmaceutical industry funded none of these trials. All trials used probiotics as adjuvant therapy to antifungal drugs. Probiotics increased the rate of short-term clinical cure (risk ratio (RR) 1.14, 95% confidence interval (CI) 1.05 to 1.24, 695

    2002-01-01

    Fungal infections of the urinary tract have a predilection for drainage structures rather than for the renal parenchyma. Of the causal factors, diabetes mellitus, immunosuppressed states, AIDS and prematurity are those most commonly encountered. The case of a young, diabetic man whose chief clinical presentation was dysuria is described. On further examination he was found to harbour fungal balls in the right kidney. Radiological manifestations of acute pyelonephritis were also present. Although primary renal candidiasis is often commensurate with systemic fungaemia, he displayed none of the clinical features of disseminate infection and, hence, was treated conservatively with oral antifungal agents. Fortuitously, spontaneous passage of fungal particulate matter in urine was later reported. A significant increase in the incidence of fungal cystitis has been found in recent years; however, the patient presents with many non-specific features of cystitis. Both sonography and CT show thickening of the bladder wall but, again, this lacks specificity. In the rare instance of prostate involvement, low attenuation foci on CT are seen within the gland. Despite the existence of a large number of fungal species, only a few are pathogenic to humans. Of those that cause disease in the urinary tract, Candida albicans is the most frequently encountered. A highly characteristic finding in such infections is of fungal balls, which are made up of aggregates of mycelia. However, care should be exercised in interpretation as a host of other conditions can mimic fungal bezoars. Although a CT scan at initial examination may qualify as the more descriptive, sonography provides a serial non-invasive means of evaluating the urinary tract. When in doubt, a urine culture clinches the diagnosis. Copyright (2002) Blackwell Science Pty Ltd

  17. Elucidating the Role of Hyposalivation and Autoimmunity in Oral Candidiasis

    2016-01-01

    Introduction Oral candidiasis (OC) is a potential oral complication in Sjögren’s Syndrome (SS). Some studies indicate that the low stimulated salivary flow and not low unstimulated salivary flow is associated with OC in SS, while others report that the underlying autoimmune disorders contributes to OC, based solely on correlation coefficients. Given the conflicting and limited existing evidence, we purposed to ascertain the role of both salivary gland dysfunction (hyposalivation based on unstimulated and stimulated flow rates) and autoimmunity (SS, other autoimmune disorders) in OC among those with SS, other salivary gland dysfunction and non-salivary gland dysfunction controls (NSGD). Methods A nested case-control study was designed within a larger NIH/NIDCR cohort. Descriptive analyses, non-parametric tests, comparative analyses, and multivariate logistic regression analyses were undertaken. Results Data on 1,526 subjects (701 SS, 247 ISS, 355 Sicca, and 223 NSGD) were obtained from the source cohort of 2,046 and analyzed for this current study. The median whole unstimulated salivary flow rate (WUS, ml/15min) was lower in SS (0.8, interquartile range (IQR) 1.8) compared to ISS (5.5, IQR 5.2, pcandidiasis. Conclusion Salivary gland dysfunction (hyposalivation with WUS being a stronger predictor than TSS) and autoimmunity (SS, other autoimmune disorders, medications i.e., DMARDS) are both independent predictors of OC. Diabetes mellitus is an independent predictor of OC among those with salivary gland dysfunction. Our findings suggest that these independent predictors should be considered in the prevention and management of OC in this population. PMID:27998016

    Objective: To identify clinical spectrum, management and outcome of neonatal candidiasis. Methods: The retrospective study was conducted at the Shifa International Hospital, Islamabad, Pakistan, and comprised microbiological records of all the babies admitted to the Neonatal Intensive Care Unit from January 2009 to January 2014 that were reviewed to identify those with positive candida cultures. Medical records were analysed for demographic and clinical spectrum features, management and outcome. SPSS 16 was used statistical analysis. Results: Of the total 1550 neonatal admissions, 560 (36 percent) had positive cultures, and, of them, candida was isolated in 49(8.8 percent) neonates. Among them, 13(26 percent) had candida albicans and the rest had candida species. Majority were males 34(70 percent), and preterm with 30(61 percent) being <37 weeks. The mean birth weight was 2000±873 grams. Mean age at admission was 6±7.6 days. Overall, 39(80 percent) had >2 risk factors. The commonest site of isolation was blood in 41(84 percent). Besides, 32 (65 percent) received fluconazole alone for treatment. Mean duration of anti-fungal therapy was 10±5 days (range: 1-21 days). Twelve (24 percent) neonates expired and the cause of death was candida sepsis in 10(20 percent) cases. Mortality was not significantly associated with gender, place of birth, gestation, risk factors, length of stay, prior antibiotic exposure or receipt of antifungal prophylaxis except those who were <1500 grams (p<0.05). Conclusion: Approximately one in ten at-risk neonates may develop candida sepsis with high mortality. Early institution of anti-fungal therapy may prove to be life-saving. (author)

    SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy. © The Author(s) 2014.

    Saliva plays an important role in maintaining microbial homeostasis in the oral cavity, while salivary gland hypofunction predisposes the oral mucosa to pathologic alteration and increases the risk for oral candidiasis. This study sought to determine the salivary flow rate (SFR) and secretory immunoglobulin A (SIgA) levels in HIV-positive and HIV-negative individuals and evaluate their relationship with the determinants of oral candidiasis. Sixty HIV-positive (30 with and 30 without oral candidiasis) and 30 healthy HIV-negative individuals were enrolled. Cotton pellet was weighed pre- and post-saliva collection for the assessment of SFR, while SIgA levels were estimated by commercial ELISA (Diametra, Italy) kit. The mean ± SD, SFR and SIgA levels in HIV-positive individuals with candidiasis, without candidiasis and HIV-negative controls were 0.396 ± 0.290, 0.546 ± 0.355 and 0.534 ± 0.214 ml/min and 115.891 ± 37.621, 136.024 ± 51.075 and 149.418 ± 31.765 µg/ml, respectively. A positive correlation between low CD4 counts (indicator of immunodeficiency) and SIgA was observed in HIV-positive individuals with candidiasis (r = 0.373, p = 0.045). We also report here for the first time the significant decrease in SFR and SIgA levels in individuals presenting with pseudomembranous type of oral candidiasis and Candida albicans infection.

    Recent high-profile cases have heightened the need for a formal structure to monitor achievement and maintenance of surgical competence. Logbooks, morbidity and mortality meetings, videos and direct observation of operations using a checklist, motion analysis devices, and virtual reality simulators are effective tools for teaching and evaluating surgical skills. As the operating theater is also a place for training, there must be protocols and guidelines, including mandatory standards for supervision, to ensure that patient care is not compromised. Patients appreciate frank communication and honesty from surgeons regarding their expertise and level of competence. To ensure that surgical competence is maintained and keeps pace with technologic advances, professional registration bodies have been promoting programs for recertification. They evaluate performance in practice, professional standing, and commitment to ongoing education.

    The amino sugar N-acetylglucosamine (GlcNAc) is an in vitro inducer of the hyphal mode of growth of the opportunistic pathogen Candida albicans. The development of hyphae by C. albicans is considered to contribute to the pathogenesis of mucosal oral candidiasis. GlcNAc is also a commonly used nutritional supplement for the self-treatment of conditions such as arthritis. To date, no study has investigated whether ingestion of GlcNAc has an effect on the in vivo growth of C. albicans or the pathogenesis of a C. albicans infection. Using a murine model of oral candidiasis, we have found that administration of GlcNAc, but not glucose, increased oral symptoms of candidiasis and fungal burden. Groups of mice were given GlcNAc in either water or in a viscous carrier, i.e., 1% methylcellulose. There was a dose-dependent relationship between GlcNAc concentration and the severity of oral symptoms. Mice given the highest dose of GlcNAc, 45.2 mM, also showed a significant increase in fungal burden, and increased histological evidence of infection compared to controls given water alone. We propose that ingestion of GlcNAc, as a nutritional supplement, may have an impact on oral health in people susceptible to oral candidiasis.

    The clinical significance of polymicrobial interactions, particularly those between commensal species with high pathogenic potential, remains largely understudied. Although the dimorphic fungal species Candida albicans and the bacterium Staphylococcus aureus are common cocolonizers of humans, they are considered leading opportunistic pathogens. Oral candidiasis specifically, characterized by hyphal invasion of oral mucosal tissue, is the most common opportunistic infection in HIV(+) and immunocompromised individuals. In this study, building on our previous findings, a mouse model was developed to investigate whether the onset of oral candidiasis predisposes the host to secondary staphylococcal infection. The findings demonstrated that in mice with oral candidiasis, subsequent exposure to S. aureus resulted in systemic bacterial infection with high morbidity and mortality. Histopathology and scanning electron microscopy of tongue tissue from moribund animals revealed massive C. albicans hyphal invasion coupled with S. aureus deep tissue infiltration. The crucial role of hyphae in the process was demonstrated using a non-hypha-producing and a noninvasive hypha-producing mutant strains of C. albicans. Further, in contrast to previous findings, S. aureus dissemination was aided but not contingent upon the presence of the Als3p hypha-specific adhesion. Importantly, impeding development of mucosal C. albicans infection by administering antifungal fluconazole therapy protected the animals from systemic bacterial disease. The combined findings from this study demonstrate that oral candidiasis may constitute a risk factor for disseminated bacterial disease warranting awareness in terms of therapeutic management of immunocompromised individuals.

    Some yeast agents including Candida albicans, Candida tropicalis and Candida glabrata have a role in recurrent vulvovaginal candidiasis. We studied the frequency of both common and recurrent vulvovaginal candidiasis in symptomatic cases which were referred to Urmia Medical Sciences University related gynecology clinics using morphologic and molecular methods. The aim of this study was the identification of Candida species isolated from recurrent vulvovaginal candidiasis cases using a rapid and reliable molecular method. Vaginal swabs obtained from each case, were cultured on differential media including cornmeal agar and CHROM agar Candida. After 48 hours at 37℃, the cultures were studied for growth characteristics and color production respectively. All isolates were identified using the molecular method of PCR - restriction fragment length polymorphism. Among all clinical specimens, we detected 19 ( 16 % ) non fungal agents, 87 ( 82.1 % ) yeasts and 2 ( 1.9 % ) multiple infections. The yeast isolates identified morphologically included Candida albicans ( n = 62 ), Candida glabrata ( n = 9 ), Candida tropicalis ( n = 8 ), Candida parapsilosis ( n = 8 ) and Candida guilliermondii and Candida krusei ( n = 1 each ). We also obtained very similar results for Candida albicans, Candida glabrata and Candida tropicalis as the most common clinical isolates, by using PCR - Restriction Fragment Length Polymorphism. Use of two differential methods, morphologic and molecular, enabled us to identify most medically important Candida species which particularly cause recurrent vulvovaginal candidiasis.

    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

    Full Text Available Purpose. The aim of this study is to determine the incidence and the predictors of ocular candidiasis among patient with Candida fungemia. Methods. We retrospectively reviewed the charts of all patients diagnosed with candidemia at the University of Kansas Medical Center during February 2000–March 2010. Data regarding patients’ demographics, clinical characteristics, laboratory results, and ophthalmology examination findings were collected. Results. A total of 283 patients with candidemia were enrolled. The mean age (± standard deviation was 55 ± 18 years; 66% were male. The most commonly isolated Candida species were C. albicans (54%, C. parapsilosis (20%, C. glabrata (13%, and C. tropicalis (8%. Only 144 (51% patients were evaluated by ophthalmology; however, the proportion of patients who were formally evaluated by an ophthalmologist increased during the study period (9%in 2000 up to 73%in 2010; P<0.0001. Evidence of ocular candidiasis was present in 18 (12.5% patients. Visual symptoms were reported by 5 of 18 (28% patients. In multivariable analysis, no predictors of ocular candidiasis were identified. Conclusions. The incidence of ocular candidiasis among patients with fungemia remains elevated. Most patients are asymptomatic and therefore all patients with candidemia should undergo fundoscopic examination to rule out ocular involvement.

    To develop an algorithm to improve the diagnosis and treatment of patients with biliary candidiasis. We performed a prospective study of 127 patients who underwent endoscopic retrograde cholangiopancreatography, for various biliary disorders, at 3 tertiary referral centers in Germany from July 2011 through July 2012 (ClinicalTrials.gov: NCT01109550). Bile, buccal, and stool samples were collected. When indicated, endoscopic transpapillary bile duct biopsies were performed to clarify the etiology of bile duct strictures and to prove invasive fungal infections. Candida species were detected in 38 of the 127 bile samples (29.9%). By multivariate analysis patients' age and previous endoscopic sphincterotomy were independent risk factors for biliary candidiasis (P 7 d) (P = 0.089) tend to be at risk for biliary candidiasis. One patient was negative in mycological culture of bile fluid but invasive biliary candidiasis was diagnosed histologically. Of Candida subspecies detected, 36.7% were azole-resistant, such as C glabrata. Eight patients received anti-mycotic therapy, based on our algorithm. Of these, 3 had cancer with biliary tract involvement, 2 had secondary sclerosing cholangitis, 1 had retroperitoneal fibrosis, and 5 had septicemia. In all patients contamination was ruled out by smears of the endoscope channel. Gastroenterologists should be aware of frequent candida colonization in patients with cholangitis and biliary disorders. Our suggested algorithm facilitates the further clinical management.

    Despite the fact that Candida albicans is an important human fungal pathogen and Dectin-2 is a major pattern recognition receptor for fungi, our knowledge regarding the role of Dectin-2 for the host defense against disseminated candidiasis is limited. Dectin-2 deficient (Dectin-2(-/-)) mice were more susceptible to systemic candidiasis, and the susceptibility was mirrored by an elevated fungal load in the kidneys that correlated with the presence of large inflammatory foci. Phagocytosis of Candida by the macrophages lacking the Dectin-2 receptor was moderately decreased, while production of most of the macrophage-derived cytokines from Dectin-2(-/-) mice with systemic candidiasis was decreased. No striking differences among several Candida mutants defective in mannans could be detected between naïve wild-type and Dectin-2(-/-) mice, apart from the β-mannan-deficient bmt1Δ/bmt2Δ/bmt5Δ triple mutant, suggesting that β-mannan may partially mask α-mannan detection, which is the major fungal structure recognized by Dectin-2. Deciphering the mechanisms responsible for host defense against the majority of C. albicans strains represents an important step in understanding the pathophysiology of systemic candidiasis, which might lead to the development of novel immunotherapeutic strategies.

    This triple-blind trial examined the effects of Calendula officinalis vaginal cream on the treatment of vaginal Candidiasis (primary outcome) and sexual function (secondary outcome). Married women aged 18-45 years with vaginal Candidiasis (n = 150) were recruited from April to October 2014 and randomized into Calendula and clotrimazole groups, using 5-g vaginal cream every night for seven nights. Clinical and laboratory assessments were conducted at 10-15 and 30-35 days after intervention and the female sexual function index was assessed at 30-35 days. Six women were lost to follow-up. The frequency of testing negative for Candidiasis in the Calendula group was significantly lower at the first (49% vs. 74%; odds ratio (OR) 0.32; 95% confidence interval (CI) 0.16-0.67) but higher at the second (77% vs. 34%; OR 3.1; 95% CI 1.5-6.2) follow-up compared to the clotrimazole group. The frequency of most signs and symptoms were almost equal in the two groups at the first follow-up, but were significantly lower in the Calendula group at the second follow-up. Sexual function had almost equal significant improvement in both groups. Calendula vaginal cream appears to have been effective in the treatment of vaginal Candidiasis and to have a delayed but greater long-term effect compared to clotrimazole.

    Vulvovaginal candidiasis is the most prevalent vaginal infection worldwide and Candida albicans is its major agent. Vulvovaginal candidiasis is characterized by disruption of the vaginal microbiota composition, as happens following large spectrum antibiotic usage. Recent studies support the effectiveness of oral and local probiotic treatment for prevention of recurrent vulvovaginal candidiasis. Saccharomyces cerevisiae is a safe yeast used as, or for, the production of ingredients for human nutrition and health. Here, we demonstrate that vaginal administration of probiotic Saccharomyces cerevisiae live yeast (GI) and, in part, inactivated whole yeast Saccharomyces cerevisiae (IY), used as post-challenge therapeutics, was able to positively influence the course of vaginal candidiasis by accelerating the clearance of the fungus. This effect was likely due to multiple interactions of Saccharomyces cerevisiae with Candida albicans. Both live and inactivated yeasts induced coaggregation of Candida and consequently inhibited its adherence to epithelial cells. However, only the probiotic yeast was able to suppress some major virulence factors of Candida albicans such as the ability to switch from yeast to mycelial form and the capacity to express several aspartyl proteases. The effectiveness of live yeast was higher than that of inactivated whole yeast suggesting that the synergy between mechanical effects and biological effects were dominant over purely mechanical effects. The protection of epithelial cells to Candida-induced damage was also observed. Overall, our data show for the first time that Saccharomyces cerevisiae-based ingredients, particularly the living cells, can exert beneficial therapeutic effects on a widespread vaginal mucosal infection.

    The study was set to detect Candida species in female genital discharge and validate the associated risk factors. A prospective study of female genital swabs collected from women with abnormal vaginal discharge (test group) and a control group who were attending gynaecology, family planning, antenatal care or HIV/STI clinics of Aminu Kano Teaching Hospital, Kano Nigeria and analysed for microscopy and culture in microbiology laboratory from December 2008 to December 2009. Data on epidemiologic indices were collected from the patients, using structured interviewer- administered questionnaires. Candida species were detected in the test group in 60% (n=600/1000) cases of infective vaginal discharge while 12% (120/1000) in the control group. The isolation rate of Candida albicans was 69% more than the non- albicans. Distribution of vaginal candidiasis in the test group, was prevalent in young adults age group of 21 to 30 years with 50% (n=300/600), in patients with pregnancy 38% (n=225/600) and patients with chronically debilitating illnesses 26% (n=157/600). The result shows that vaginal candidiasis is quite common and Candida albicans is the most prevalent species. We therefore recommend early diagnosis and prompt treatment of vaginal candidiasis in all women clinics especially among the patients with chronic debilitating illness, pregnancy and young adults in order to avert the complications of vaginal candidiasis and reduce HIV transmission.

    We reported a rare case of recurrent vulvovaginal candidiasis (RVVC) in this study. Through dynamic evaluation of the vaginal micro-ecosystem, we found that only depuratory degree, spores, blastospores, and hyphae were specific indicators and the "barometer" of RVVC development. Therefore, an understanding of vaginal micro-ecological changes can help clinicians to improve the treatment of patients with RVVC.

    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.

    The primary aim of the study was to gain insight into the relative risk of clinically relevant oral candidiasis following inhaled corticosteroid (ICS) initiation over time. A secondary aim was to analyse the influence of patient characteristics and co-medication on the occurrence of this adverse effect. Drug prescription data from 1994 to 2011 were retrieved from the IADB.nl database. To study the influence of ICS use on occurrence of oral candidiasis, a prescription symmetry analysis was used, including patients using medication for oral candidiasis up to 1 year before or after ICS initiation. The relative risk was calculated by dividing the number of patients receiving medication for oral candidiasis after ICS initiation by the number of patients receiving the same medication before ICS initiation. Sub-analyses were conducted to compare the relative risks at several time points after ICS initiation and to account for therapy persistence by only including chronic users of ICS. A multivariate logistic regression model was used to identify predictive factors. A total of 52,279 incident users of ICS therapy were identified, of which 1,081 received medication for oral candidiasis up to 1 year before or after ICS initiation. A total of 701 patients received medication for oral candidiasis after ICS initiation, while 361 received these medications in the reversed sequence, resulting in a sequence ratio (SR) of 1.94 (95 % CI 1.71-2.21). In the first 3 months after ICS initiation, the SR was 2.72 (95 % CI 2.19-3.38) and then decreased to 1.47 (95 % CI 1.11-1.95) 9-12 months after ICS initiation. Predictive factors were higher daily dose of ICS and concomitant use of oral corticosteroids. This study found a significant and clinically relevant increased number of patients receiving medication for oral candidiasis in the first year after therapy initiation with ICS. Relative risk is highest in the first 3 months, but remains increased up to at least 1 year after ICS

    Full Text Available El Síndrome de Inmunodeficiencia Adquirida (SIDA es un proceso patológico detectado por vez primera en los Estados Unidos de América en 1981 (aunque se plantea que su origen geográfico está en África. Adquiere, de inmediato, un carácter epidémico explosivo, que luego se extiende a otras partes del mundo y comienza a adoptar el carácter de un grave problema de salud mundial. Los seres humanos viven en armonía relativa con una serie de virus, bacterias, parásitos y hongos que no causan enfermedades a las personas sanas cuyas defensas inmunológicas están intactas, pero estos microorganismos pueden aprovecharse de un sistema inmunitario debilitado, como el de una persona infectada por el Virus de Inmunodeficiencia Humana (VIH. Las infecciones que ocasionan reciben el nombre de infecciones oportunistas, dentro de las cuales se encuentra la candidiasis, que es una infección fúngica causada por cualquiera de las especies del género Candida. En pacientes con VIH, la infección oportunista más frecuente es la Candida y de ésta la especie que más prevalece es la Candida albicans. La candidiasis más común es la seudomembranosa, localizada generalmente en la lengua, paladar duro y blando y la mucosa del carrillo. Las manifestaciones clínicas más frecuentes de la candidiasis son las infecciones por Candida de la cavidad bucal y el esófago. En los pacientes infectados por el VIH, asintomáticos, la presencia de candidiasis bucal suele anunciar la transición hacia el SIDA. El odontólogo puede reconocerla en sus diferentes formas de presentación y muchas veces, a través de su presencia, puede hacer diagnóstico precoz de enfermedades como el SIDA.Acquired Immunodeficiency Syndrome is a pathological process detected for the first time in 1981 in the United States (although its geographic origin is said to be in Africa.

    Candidiasis, the infection caused by Candida albicans , is one of the most common infections of the oral cavity in humans. Candidiasis causes irritation and is known for its carcinogenic effects. Thus, it is important to recognize the predisposing factors for this opportunistic infection. Several previous studies have demonstrated an increased frequency of vaginal candidiasis in relation to oral contraceptive consumption. Only a few studies on the relation between oral contraceptives and oral candidiasis have been previously conducted. This study aims to evaluate the possible relation between oral contraceptive pills and oral candidiasis. This analytic, case-control study included 40 non-pregnant women divided into two groups: 20 who used oral contraceptive pills and 20 who did not. The groups were matched according to age, oral health, and past and present medical history. Samples were collected from the tongue's dorsum using a cotton swab and inoculated on CHROMagar culture plates. The frequency of positive cultures and the number of Candida colonies were compared between the two groups using independent t-tests and Mann-Whitney statistical tests with SPSS18 software. The frequency of positive cultures of Candida albicans was higher (P value = 0.03) for the case group. Also, the number of C. albicans and C. krusei was significantly higher for the case group compared to the control group (P value = 0.04, P value = 0.03). The results of the present study demonstrate that oral contraceptives containing estradiol can lead to Candida colonization in the oral cavity. It is recommended that further studies comparing the influence of oral contraceptives on Candida's adherence to the epithelium is highly recommended.

    Blood cultures are positive for Candida species in candidiasis, respectively. Non-culture tests such as mannan, anti-mannan antibody, Candida albicans germ tube antibody (CAGTA), 1,3-β-d-glucan (BDG), the T2Candida nanodiagnostic panel, and polymerase chain reaction (PCR) are available for clinical use, but their roles in patient care are uncertain. Sensitivity/specificity of combined mannan/anti-mannan, BDG, T2Candida and PCR for candidemia are ~80%/80%, ~80%/80%, ~90%/98%, and ~90%/90%, respectively. Limited data for intra-abdominal candidiasis suggest CAGTA, BDG sensitivity/specificity of ~65%/75% and PCR sensitivity of ~85–90%. PCR specificity has varied widely for intra-abdominal candidiasis (33–97%), and T2Candida data are lacking. Tests will be useful if restricted to cases in which positive and negative predictive values (PPVs, NPVs) differ in a clinically meaningful way from the pre-test likelihood of invasive candidiasis. In some patients, PPVs are sufficient to justify antifungal treatment, even if blood cultures are negative. In most patients, NPVs of each test are excellent, which may support decisions to withhold antifungal therapy. If test results are not interpreted judiciously, non-culture diagnostics may have unintended consequences for stewardship and infection prevention programs. In particular, discrepant non-culture test-positive/culture-negative results may promote inappropriate antifungal treatment of patients who are unlikely to have candidiasis, and lead to spurious reporting of hospital-acquired infections. In conclusion, non-culture Candida diagnostics have potential to advance patient care, but this promise will be realized only if users understand tests’ strengths and limitations, and plan proactively for how best to employ them at their hospitals.

    Vulvovaginal candidiasis (VVC) or vaginal candidiasis is a common fungal infection of the genitals causing inflammation, irritation, itching, and vaginal discharge. Common yeast infections are caused by the yeast species C. albicans. However, there are other species of Candida such as C. dubliniensis which are considered as the causative agents of this infection. Hydrolytic enzymes such as proteinase and coagulase are known as virulence factors. The aim of this study was the molecular confirmation and differentiation of C. dubliniensis among C. albicans strains isolated from women with vulvovaginal candidiasis by PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) and the evaluation of proteinase and coagulase activities. A total of 100 C. albicans strains isolated from women with vulvovaginal candidiasis referred to Shiraz medical clinics were enrolled in the study. All the isolates were primarily identified by conventional methods. PCR-RFLP method was used for the confirmation and identification of C. albicans and C. dubliniensis. Moreover, in vitro proteinase and coagulase activities of these isolates were evaluated using bovine serum albumin media and classical rabbit plasma tube test. As a result, PCR-RFLP identified 100% of the isolates as C. albicans, and no C. dubliniensis could be identified in this study. 84% of the isolates showed proteinase activity, whereas coagulase activity was only detected in 5% of the isolates. This study reveals that C. dubliniensis plays no role in vaginal candidiasis in Iranian patients. Proteinase production could be an essential virulence factor in C. albicans pathogenicity, but coagulase activity has less potential in this matter. Copyright © 2017 Elsevier Ltd.

    OBJECTIVE To determine if chlorhexidine can be used as an intervention to prolong the time to relapse of oral candidiasis. SUBJECTS AND METHODS A double-blinded randomized clinical trial was performed in 75 HIV/AIDS subjects with oral candidiasis. Clotrimazole troche was prescribed, and the subjects were re-examined every 2 weeks until the lesions were completely eradicated. The subjects were then randomly divided into two groups; 0.12% chlorhexidine (n = 37, aged 22–52 years, mean 34 years) and 0.9% normal saline (n = 38, aged 22–55 years, mean 38 years). They were re-examined every 2 weeks until the next episode was observed. RESULTS The time to recurrence of oral candidiasis between the chlorhexidine and the saline group was not statistically significant (P > 0.05). The following variables were significantly associated with the time of recurrence; frequency of antifungal therapy (P = 0.011), total lymphocyte (P = 0.017), alcohol consumption (P = 0.043), and candidiasis on gingiva (P = 0.048). The subjects with lower lymphocyte showed shorter oral candidiasis-free periods (P = 0.034). CONCLUSIONS Chlorhexidine showed a small but not statistically significant effect in maintenance of oral candidiasis-free period. This lack of significance may be due to the small sample size. Further study should be performed to better assess the size of the effect, or to confirm our findings. PMID:18627504

    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.

    Despite a paucity of data regarding both the incidence of ocular candidiasis and the utility of ophthalmic examination in critically ill patients, routine ophthalmic examination is recommended for critically ill patients with candidaemia. The objectives were to estimate the incidence of ocular candidiasis and evaluate whether ophthalmic examination influenced subsequent management of these patients. We conducted a ten-year retrospective observational study. Data were extracted for all ICU patients who were blood culture positive for fungal infection. Risk factors for candidaemia and eye involvement were quantified and details regarding ophthalmic examination were reviewed. Candida species were cultured in 93 patients. Risk factors for ocular candidiasis were present in 57% of patients. Forty-one percent of patients died prior to ophthalmology examination and 2% of patients were discharged before candidaemia was identified. During examination, signs of ocular candidiasis were only present in one (2.9%) patient, who had a risk factor for ocular candidiasis. Based on these findings, the duration of antifungal treatment for this patient was increased. Ocular candidiasis occurs rarely in critically ill patients with candidaemia, but because treatment regimens may be altered when diagnosed, routine ophthalmic examination is still indicated.

    The aim of this study was to evaluate procalcitonin (PCT), C-reactive protein (CRP), platelet count (PLT) and serum lactate dehydrogenase (LDH) as early markers for diagnosis of SIRS, bacterial sepsis and systemic candidiasis in intensive care unit (ICU) patients. Based on blood culture results, the patients were divided into a sepsis group (70 patients), a SIRS group (42 patients) and a systemic candidiasis group (33 patients). PCT, CRP, LDH and PLT levels were measured on day 0 and on day 2 from the sepsis symptom onset. PCT levels were higher in Gram negative sepsis than those in Gram positive sepsis, although the P value between the two subgroups is not significant (P=0.095). Bacterial sepsis group had higher PCT and CRP levels compared with the systemic candidiasis group, whereas PLT and LDH levels showed similar levels in these two subgroups. The AUC for PCT (AUC: 0.892, P candidiasis groups (P=0.093 N.S.). In conclusion, PCT can be used as a preliminary marker in the event of clinical suspicion of systemic candidiasis; however, low PCT levels (candidiasis and SIRS groups.

Analysis of risk factors for candidiasis invasive and evaluation of the contribution of colonization index (CI) in the diagnosis of the systematic candidiasis in medical intensive care. Prospective observational study (October 2007 to October 2009). The selected patients present risk factors of system IC candidiasis with an infectious syndrome or clinical signs suggestive of Candida infection and hospitalized more than 48 hours in medical intensive care unit. Pittet's colonization index was calculated at admission and then once a week added to a blood culture. Patients were classified according to level of evidence of Candida infection and the degree of colonization (CIcandidiasis. In multivariate analysis, the corticosteroid therapy was associated with a high colonisation (IC ≥ 0.5) and neutropenia with a high risk of systemic candidiasis. The positive predictive value of CI was 26%. The negative predictive value was 98%, the sensitivity and specificity was 93% and 48% respectively. CI has the advantage to provide a quantified data of the patient's situation in relation to the colonization. But, it isn't helpful with patients having an invasive candidiasis in medical intensive care unit. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Antibodies targeting IL-17A or its receptor, IL-17RA, are approved to treat psoriasis and are being evaluated for other autoimmune conditions. Conversely, IL-17 signaling is critical for immunity to opportunistic mucosal infections caused by the commensal fungus Candida albicans, as mice and humans lacking the IL-17R experience chronic mucosal candidiasis. IL-17A, IL-17F, and IL-17AF bind the IL-17RA-IL-17RC heterodimeric complex and deliver qualitatively similar signals through the adaptor Act1. Here, we used a mouse model of acute oropharyngeal candidiasis to assess the impact of blocking IL-17 family cytokines compared with specific IL-17 cytokine gene knockout mice. Anti-IL-17A antibodies, which neutralize IL-17A and IL-17AF, caused elevated oral fungal loads, whereas anti-IL-17AF and anti-IL-17F antibodies did not. Notably, there was a cooperative effect of blocking IL-17A, IL-17AF, and IL-17F together. Termination of anti-IL-17A treatment was associated with rapid C. albicans clearance. IL-17F-deficient mice were fully resistant to oropharyngeal candidiasis, consistent with antibody blockade. However, IL-17A-deficient mice had lower fungal burdens than anti-IL-17A-treated mice. Act1-deficient mice were much more susceptible to oropharyngeal candidiasis than anti-IL-17A antibody-treated mice, yet anti-IL-17A and anti-IL-17RA treatment caused equivalent susceptibilities. Based on microarray analyses of the oral mucosa during infection, only a limited number of genes were associated with oropharyngeal candidiasis susceptibility. In sum, we conclude that IL-17A is the main cytokine mediator of immunity in murine oropharyngeal candidiasis, but a cooperative relationship among IL-17A, IL-17AF, and IL-17F exists in vivo. Susceptibility displays the following hierarchy: IL-17RA- or Act1-deficiency > anti-IL-17A + anti-IL-17F antibodies > anti-IL-17A or anti-IL-17RA antibodies > IL-17A deficiency. © Society for Leukocyte Biology.

    Vulvovaginal candidiasis is a common infection among women worldwide. According to previous epidemiological studies, Candida albicans is the most common species of Candida. The prevalence of non-Candida species, however, is increasing. Identification of Candida species among the population will not only help health professionals to choose suitable antifungal treatments, but also prevent development of drug resistance. The aim of this study was to identify, using chromogenic agar medium, the Candida species associated with vulvovaginal candidiasis among a sample of the Iranian population. In a prospective cohort study during a two year period from March 2006 to March 2008, swab samples of vaginal discharge/secretion were taken from 200 patients admitted to the gynecology clinic of Mahdieh Hospital (Tehran, Iran) with a clinical presentation suggestive of vulvovaginal candidiasis. The isolates obtained were cultured on Sabouraud dextrose agar and chromogenic agar medium. Candida species were also identified by germ tube formation in serum, chlamydospore production on Corn Meal Agar and carbohydrate absorption using the API 20C-AUX kit. Participants were asked to complete a questionnaire investigating the risk factors associated with candidiasis. An assessment of the different species of recurrent and non-recurrent candidiasis was also made. Descriptive statistics, chi-square test, and t-test were used to analyze the data. A total of 191 isolates were obtained from 175 vaginal specimens. Candida albicans accounted for 67% of the strains including single and mixed infections. The other identified species were Candida glabrata (18.3%), Candida tropicalis (6.8%), Candida krusei (5.8%), Candida parapsilosis (1.6%), and Candida guilliermondii (0.5%) respectively. Mixed infection with two or more species of Candida was seen in 10.3% of patients. The most common mixed cause was the combination of Candida albicans and Candida glabrata.

    The aim of this study was to evaluate oral epithelial cells of the oral mucosa infected by Candida albicans using exfoliative cytology. Oral smears were collected from clinically normal-appearing mucosa by liquid-based exfoliative cytology of 60 individuals (30 patients with oral candidiasis and 30 healthy controls matched for age and gender) and analysed for morphologic and cytomorphometric technique. Morphologically, candida-infected epithelial cells exhibited nuclear enlargement, perinuclear rings, discrete orangeophilia, and cytoplasmic vacuoles. The cytomorphometric analysis demonstrated that the cytoplasmic area (CA) of the epithelial cells was diminished in patients undergoing candidiasis as compared to the non-infected controls. In addition, there was an augmentation in nuclear area (NA) and NA/CA area ratio. This study revealed that oral mucosa of patients undergoing candidal infection exhibited significant changes in the size and shape of the oral epithelial cells. © 2010 Blackwell Verlag GmbH.

    Congenital cutaneous candidiasis is a very rare disease with less than 100 cases published in the medical literature. Neonates having this disease present with systemic skin lesions caused by intrauterine Candida infections. We present a case of threatened premature delivery due to Candida chorioamnionitis, which caused both maternal postpartum endometritis and neonatal congenital cutaneous candidiasis. A 34-year-old woman who was admitted for fetal membrane bulging at 20 weeks of gestation underwent McDonald cervical cerclage. We diagnosed threatened premature delivery due to intrauterine infection; therefore, we terminated the gestation by cesarean section at 24 weeks of gestation. Fungi-like yeast was detected in infantile gastric juice. Histopathological findings of the placenta revealed that Candida albicans mycelium invaded the placenta, chorioamniotic membrane and umbilical cord. © 2012 The Authors.

    Abstract Candidiasis is a common fungal infection that is prevalent in immunocompromised individuals. In this study, an oral vaccine against Candida albicans was developed by using the molecular display approach. Enolase 1 protein (Eno1p) of C. albicans was expressed on the Lactobacillus casei cell surface by using poly-gamma-glutamic acid synthetase complex A from Bacillus subtilis as an anchoring protein. The Eno1p-displaying L. casei cells were used to immunize mice, which were later chall...

    Humans or mice subjected to immunosuppression, such as corticosteroids or anti-cytokine biologic therapies, are susceptible to mucosal infections by the commensal fungus Candida albicans. Recently it has become evident that the Th17/IL-17 axis is essential for immunity to candidiasis, but the downstream events that control immunity to this fungus are poorly understood. The CCAAT/Enhancer Binding Protein-β (C/EBPβ) transcription factor is important for signaling by multiple inflammatory stimuli, including IL-17. C/EBPβ is regulated in a variety of ways by IL-17, and controls several downstream IL-17 target genes. However, the role of C/EBPβ in vivo is poorly understood, in part because C/EBPβ-deficient mice are challenging to breed and work with. In this study, we sought to understand the role of C/EBPβ in the context of an IL-17-dependent immune response, using C. albicans infection as a model system. Confirming prior findings, we found that C/EBPβ is required for immunity to systemic candidiasis. In contrast, C/EBPβ(-/-) mice were resistant to oropharyngeal candidiasis (OPC), in a manner indistinguishable from immunocompetent WT mice. However, C/EBPβ(-/-) mice experienced more severe OPC than WT mice in the context of cortisone-induced immunosuppression. Expression of the antimicrobial peptide β-defensin (BD)-3 correlated strongly with susceptibility in C/EBPβ(-/-) mice, but no other IL-17-dependent genes were associated with susceptibility. Therefore, C/EBPβ contributes to immunity to mucosal candidiasis during cortisone immunosuppression in a manner linked to β-defensin 3 expression, but is apparently dispensable for the IL-17-dependent response.

    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.

    Full Text Available Introduction: Vaginits is probably the most common infection in women during their reproductive years, resulting in 5-10 million health-care visits a year, worldwide. Vulvovaginal candidiasis (vvc is the second-most common form of vaginitis in the United States, which is associated with use of oral contraceptives containing high levels of estrogen and hormonal therapies. Midwives play an important role not only in the assessment and management of vaginal infections, but also in educating women about vaginal health. Recognizing risk factors associated with infections are the key to vaginal health.The aim of this study was to determine the prevalence and risk factors of Candidal vaginitis in women referring to Tabriz health centers. Methods: This was a cross sectional study carried out on 1000 women aged 15-49 years who were selected by multiple random method. A sample of vaginal discharge was taken from the posterior fornix of the cervix and from the vaginal wall using sterile cotton swabs. The mycelium was observed by microscopic examination of a wet mount of the secretions. Another sample was taken for culturing in Agar sabura and transported to the laboratory. In addition, questionnaires with personal and reproductive information were completed. Data was analyzed by using SPSS version 15 and chi-square and, t student statistical tests were used for analysis. Results : This investigation indicated that prevalence of candidiasis was 25.2%. There was no meaningful statistical relationship between age, marriage age, occupation, education status, body mass index, day of menstruation cycle and abortion history with candidal vaginitis (p>.05,but a statistically significant relationship was observed between number of deliveries, vaginal Ph with candidiasis. Also, there was a reverse statistical relationship between OCP, DMPA methods and candidiasis. Conclusion: Midwives and other health professionals have an important role to play by giving more

    Esophageal candidiasis mostly occurs in the immunocompromised host. However, it may also affect healthy people and is frequently asymptomatic. The clinical significance of asymptomatic esophageal candidiasis (AEC) is still unclear. The aims of the study were to investigate the prevalence of AEC during health inspection and to identify its predisposing factors and clinical significance. A total of 49,497 subjects who underwent a health inspection that included upper endoscopy were enrolled. We retrospectively reviewed the subject's self-reporting questionnaires, medical records and endoscopic findings. We considered "long-term" follow-up to be >6 months with at least one more follow-up endoscopy. One hundred and seventy (0.4%) subjects were endoscopically diagnosed as esophageal candidiasis and 141 subjects were AEC. Multivariate analysis revealed that old age (≥60 years) was an independent risk factor for AEC (OR, 1.862, p = 0.005). The number of subjects with long-term follow-up was 79 (195.3 person-years). Among these, AEC of 64 subjects (81.0%) had disappeared on the follow-up endoscopy and was not recurrent. The other 15 subjects had AEC diagnosed more than once on the follow-up endoscopy, and 5 of them were spontaneously healed during the follow-up period. The remaining 10 subjects whose candidiasis was sustained up to the last endoscopy did not complain of symptoms during the follow-up period, and their endoscopic findings did not worsen. AEC is rare and old age is the only risk factor. AEC does not require medical care because it is a self-limited disease.

    Candidiasis is the most prevalent fungal infection affecting human and animals all over the world. This study represents the epidemiological aspects of superficial candidiasis in outpatients and in vitro antifungal susceptibility of etiologic Candida species. Clinical samples were taken from 173 patients including skin and nail scrapings (107; 61.8%), vaginal discharge (28; 16.2%), sputum (20; 11.6%), oral swabs (7; 4.0%), bronchoalveolar lavage (6; 3.5%) and 1 specimen (0.6%) of each eye tumor, gastric juice, urine, biopsy and urinary catheter and confirmed as candidiasis by direct microscopy, culture and histopathology. Susceptibility patterns of the isolated Candida species were determined using the disk diffusion and broth microdilution methods. Among 173 Candida isolates, C. albicans (72.3%) was the most prevalent species followed by C. parapsilosis (11.5%). Other identified species were C. glabrata, C. krusei, C. tropicalis, C. guilliermondii, C. intermedia and C. sake. Majority of the Candida isolates were susceptible to fluconazole (95.4%) followed by 5-flucytosine (89.6%), voriconazole (78.6%) itraconazole (48.0%) and ketoconazole (42.8%). Caspofungin was the most potent antifungal drug against C. albicans (MICs; 0.062-1 μg/mL), ketoconazole for C. parapsilosis and C. tropicalis (MICs; 0.031-0.25 μg/mL) and itraconazole for C. krusei, C. glabrata and C. guilliermondii (MICs; 0.031-1 μg/mL). This study reinforces the significance of superficial candidiasis as an important fungal infection with multiple clinical presentations. Our results further indicate that susceptibility testing to commonly used antifungals is crucial in order to select the appropriate therapeutic strategies which minimize complications while improving patients' life.

    Methods: The cross-sectional study was performed at Kowsar Gynecology Center, Motahhari educational hospital and Medical Mycology Center, Faculty of Medicine, Urmia, Iran, from October 2013 to July 2015. Those patients referred to the clinic with symptoms of vaginal discharge, itching or burning that swab samples from endo-exocervix and distal fornix discharge were taken. The vaginal discharge samples submitted to Medical Mycology Center, Urmia School of Medicine for the direct microscopic examination and cultures. Identification at the level of species was performed using CHROMagar Candida and Corn meal agar media. The molecular test polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP used for confirming culture results. For the susceptibility assay, disc diffusion method was performed with fluconazole and clotrimazole. Results: In these study 198 samples collected from patients with symptoms of vulvovaginal candidiasis, 77 vulvovaginal candidiasis cases were identified. Candida species are common in primary and recurrent cases in terms of frequency, Candida albicans (85.7%, Candida krusei (10.2% and Candida glabrata (4.1% were identified respectively. Total of 27 cases of recurrent vulvovaginal candidiasis, 10 cases were resistant to both clotrimazole and fluconazole (37% was observed that the most common species are resistant to treatment were Candida albicans by (82.1%, Candida krusei (14.3% and Candida glabrata (3.6% respectively. Drug resistance in Candida albicans, Candida krusei and Candida glabrata causing recurrent vulvovaginal candidiasis included 69.1%, 75% and 100% respectively. Conclusion: Our findings have shown frequency of resistant non-albicans Candida species to fluconazole and clotrimazole is increasing. There is a considerable difference between Candida albicans and non-albicans species, Candida glabrata for the resistance to fluconazole and clotrimazole.

    Full Text Available Abstract This study analyzed the antifungal activity of phytoconstituents from linalool on Candida spp. strains, in vitro, isolated from patients with clinical diagnoses of oral candidiasis associated with the use of a dental prosthesis. Biological samples were collected from 12 patients using complete dentures or removable partial dentures and who presented mucous with diffuse erythematous or stippled features, indicating a clinical diagnosis of candidiasis. To identify fungal colonies of the genus Candida, samples were plated onto CHROMagar Candida®. The antifungal activity of linalool, a monoterpene unsaturated constituent of basil oil, was performed using the broth microdilution technique. Then, the minimum inhibitory concentration (MIC, the two subsequent stronger concentrations and the positive controls were subcultured on Sabouraud Dextrose Agar plates to determine the minimum fungicidal concentration (MFC. The experiments were performed in triplicate and nystatin was used as a positive control in all tests. Diagnoses of oral candidiasis were verified in eight patients (66.6% and the most prevalent fungal species was Candida albicans (37.5%, followed by Candida krusei (25.0%; and Candida tropicalis (4.2%. The best antifungal activity of linalool was observed on Candida tropicalis (MIC = 500 mg/mL, followed by Candida albicans (MIC = 1.000 mg/mL, and Candida krusei (MIC = 2.000 mg/mL.Under the study conditions and based on the results obtained, it can be concluded that the Candida strains tested were susceptible to linalool.

    Candida infections are frequently encountered fungal infections in the oral mucosa. This study aimed to evaluate the effect of eliminating Candida spp. on stimulated whole salivary flow rate (SWS) in patients with oral candidiasis. This study involved 66 patients with oral candidiasis. Fifty-two consecutive patients, successfully treated by antifungal therapy, were available to examine the effect of elimination of oral Candida spp. on SWS (success group); the 14 patients who tested positive for Candida after therapy were retrospectively included (control group). SWS were used to measure saliva production. Moreover, tongue pain and xerostomia were evaluated using visual analog score (VAS). By eliminating oral Candida spp., SWS significantly increased in the success group after antifungal therapy [SWS: mean value 0.89±0.51ml/min (median 0.82ml/min: 0.15-2.14) to mean value 1.16±0.58ml/min (median 1.05ml/min: 0.2-2.93), Poral Candida spp. in patients with oral candidiasis.

    To investigate the relationship between the quantity of Candida colonies in saliva and oral candidiasis (OC), as well as to identify the threshold for distinguishing oral candidiasis from healthy carriage. A diagnostic test was conducted in 197 patients with different oral problems. The diagnosis of OC was established based on clinical features. Whole saliva samples from the subjects were cultured for Candida species. Receiver operating characteristic (ROC) curve analysis was used in this study. OC patients had significantly more Candida colony-forming units per millilitre saliva (795 cfu/ml) than asymptomatic carriers (40 cfu/ml; P candidiasis, the quantity of Candida colonies differed. The number of Candida colonies in pseudomembranous type was significantly higher than that in the erythematous type (P < 0.05). Candida albicans was the predominant species of Candida. The cut-off point with the best fit for OC diagnosis was calculated to be 266 cfu/ml. The sensitivity and specificity were 0.720 and 0.825, respectively. Analysis of the ROC curve indicated that Candida colonies had a high diagnostic value for OC, as demonstrated by the area under the curve (AUC = 0.873). Based on this study, the value of 270 cfu/ml was considered a threshold for distinguishing OC from carriage.

    There is a strong need for new broadly active antifungal agents for the treatment of oral candidiasis that not only are active against many species of Candida, including drug-resistant strains, but also evade microbial countermeasures which may lead to resistance. Host defense peptides (HDPs) can provide a foundation for the development of such agents. Toward this end, we have developed fully synthetic, small-molecule, nonpeptide mimetics of the HDPs that improve safety and other pharmaceutical properties. Here we describe the identification of several HDP mimetics that are broadly active against C. albicans and other species of Candida, rapidly fungicidal, and active against yeast and hyphal cultures and that exhibit low cytotoxicity for mammalian cells. Importantly, specificity for Candida over commensal bacteria was also evident, thereby minimizing potential damage to the endogenous microbiome which otherwise could favor fungal overgrowth. Three compounds were tested as topical agents in two different mouse models of oral candidiasis and were found to be highly active. Following single-dose administrations, total Candida burdens in tongues of infected animals were reduced up to three logs. These studies highlight the potential of HDP mimetics as a new tool in the antifungal arsenal for the treatment of oral candidiasis. PMID:24752272

    Candida albicans is a commensal organism that can be isolated from the majority of healthy individuals. However, in certain susceptible individuals C. albicans can become pathogenic leading to the mucocutaneous infection; oral candidiasis. Murine models and in vitro monolayer cultures have generated some data on the likely virulence and host factors that contribute to oral candidiasis but these models have limitations. Recently, tissue engineered oral mucosal models have been developed to mimic the normal oral mucosa but little information is available on their true representation. In this study, we assessed the histological features of three different tissue engineered oral mucosal models compared to the normal oral mucosa and analysed both cell damage and cytokine release following infection with C. albicans. Models comprised of normal oral keratinocytes and a fibroblast-containing matrix displayed more similar immunohistological and proliferation characteristics to normal mucosa, compared to models composed of an oral carcinoma cell line. Although all models were invaded and damaged by C. albicans in a similar manner, the cytokine response was much more pronounced in models containing normal keratinocytes. These data suggest that models based on normal keratinocytes atop a fibroblast-containing connective tissue will significantly aid in dissecting the molecular pathogenesis of oral candidiasis.

    Oral mucositis is a chief complication in patients undergoing hematopoietic stem cell transplantation (HSCT). It is considered a toxic inflammatory reaction that interferes with the patient's recuperation and quality of life. Oral candidiasis is a common fungal infection observed in dental practice, particularly in immunocompromised patients. The aim of this study was to evaluate the presence of oral mucositis and oral candidiasis in patients who underwent HSCT and their correlation with the chemotherapeutic nadir (lowest possible outcome). We evaluated patients with different diagnoses who underwent HSCT at the Hospital Erasto Gaertner. No chemotherapeutic nadir curves could be associated with mucositis, and patients had different presentations of mucositis. No patient developed oral candidiasis during hospitalization. Together with cell counts, we collected demographic data including age, oral hygiene, habits harmful to health, and the use of oral prostheses. It was observed that patients who smoked cigarettes before hospitalization showed less mucositis, resulting in no feeding problems or other comorbid conditions due to the effect of mucositis. However, the nadir of the chemotherapy curve, in isolation, is not a predictive tool for the appearance (or no appearance) of oral mucositis.

    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.

    The objective of this study is to assess the efficacy and safety of miconazole for treating oral candidiasis. Twelve electronic databases were searched for randomized controlled trials evaluating treatments for oral candidiasis and complemented by hand searching. The clinical and mycological outcomes, as well as adverse effects, were set as the primary outcome criteria. Seventeen trials were included in this review. Most studies were considered to have a high or moderate level of bias. Miconazole was more effective than nystatin for thrush. For HIV-infected patients, there was no significant difference in the efficacy between miconazole and other antifungals. For denture wearers, microwave therapy was significantly better than miconazole. No significant difference was found in the safety evaluation between miconazole and other treatments. The relapse rate of miconazole oral gel may be lower than that of other formulations. This systematic review and meta-analysis indicated that miconazole may be an optional choice for thrush. Microwave therapy could be an effective adjunct treatment for denture stomatitis. Miconazole oral gel may be more effective than other formulations with regard to long-term results. However, future studies that are adequately powered, large-scale, and well-designed are needed to provide higher-quality evidence for the management of oral candidiasis. © 2015 John Wiley & Sons A/S.

    To describe a severe case of bacterial sepsis and disseminated candidiasis in a previously healthy dog. Fungal sepsis was identified in a 2-year-old dog following intestinal dehiscence 4 days after abdominal surgery. Septic peritonitis was identified at admission and evidence of dehiscence at the previous enterotomy site was found during an exploratory laparotomy. Both gram-positive cocci and Candida albicans were cultured from the abdominal cavity. Candida sp. was also subsequently cultured from a central venous catheter. Euthanasia was performed due to failure to respond to therapy. Fungal organisms, morphologically consistent with Candida spp., were found in the lungs and kidney on postmortem histopathologic examination indicating disseminated candidiasis. Candida peritonitis is a well-recognized entity in humans and contributes to morbidity and mortality in critically ill patients. Abdominal surgery, intestinal perforation, presence of central venous catheters, and administration of broad-spectrum antibiotics are all considered to be suspected risk factors. This report describes the first known case of systemic candidiasis occurring secondary to Candida peritonitis and bacterial sepsis in a critically ill dog.

    Full Text Available Invasive candidiasis caused by Candida albicans and non-albicans Candida (NAC present a serious disease threat. Although the echinocandins are recommended as the first line of antifungal drug class, resistance to these agents is beginning to emerge, demonstrating the need for new antifungal agents. Host defense peptides (HDP exhibit potent antifungal activity, but as drugs they are difficult to manufacture efficiently, and they are often inactivated by serum proteins. HDP mimetics are low molecular weight non-peptide compounds that can alleviate these problems and were shown to be membrane-active against C. albicans and NAC. Here, we expand upon our previous works to describe the in vitro and in vivo activity of 11 new HDP mimetics that are active against C. albicans and NAC that are both sensitive and resistant to standard antifungal drugs. These compounds exhibit minimum inhibitory/fungicidal concentration (MIC/MFC in the µg/mL range in the presence of serum and are inhibited by divalent cations. Rapid propidium iodide influx into the yeast cells following in vitro exposure suggested that these HDP mimetics were also membrane active. The lead compounds were able to kill C. albicans in an invasive candidiasis CD-1 mouse model with some mimetic candidates decreasing kidney burden by 3–4 logs after 24 h in a dose-dependent manner. The data encouraged further development of this new anti-fungal drug class for invasive candidiasis.

    To retrospectively evaluate thin-section computed tomographic (CT) findings in hematopoietic stem cell transplant (ie, bone marrow transplant) patients with histopathologically proved pulmonary candidiasis. Ethical approval was obtained from the institutional review board of each of the three institutions; informed consent was not required. The study included 17 hematopoietic stem cell transplant recipients with proved pulmonary candidiasis. Histopathologic specimens were acquired at transbronchial biopsy (n = 8), open lung biopsy (n = 6), and autopsy (n = 3). The patients included seven men and 10 women (age range, 20-62 years; mean age, 37 years). The thin-section CT scans were retrospectively reviewed by two thoracic radiologists for the presence, appearance, and distribution of parenchymal abnormalities. Multiple nodules were present in 15 (88%) patients, including centrilobular nodules and tree-in-bud pattern in seven (41%) patients. Nodules were bilateral in 12 patients and unilateral in three. An associated halo of ground-glass opacity was identified in five (33%) patients. Nodules were the only CT finding in five patients (29%). Areas of air-space consolidation were identified in 11 (65%) patients. Areas of ground-glass opacity were seen in six (35%) of 17 patients and were always associated with other abnormalities. Other less common CT findings included pleural effusion (n = 3), thickening of the bronchial walls (n = 2), and cavitation (n = 1). The most common thin-section CT findings of pulmonary candidiasis in hematopoietic stem cell transplant patients are multiple bilateral nodular opacities often associated with areas of consolidation.

    Histatin5 (Hst-5) is a member of the histatin family of antimicrobial peptides secreted by human parotid and submandibular glands. With the natural antibacterial activity, it plays an important role in the first-line barrier of oral cave against pathogens, especially for the fungal intrusion. In this study, we explored the utility of Hst-5 in the treatment of vulvovaginal candidiasis, a common condition of women of the childbearing age. We used a synthesized Hst-5 over five consecutive days as the topical treatment in a murine model of vulvovaginal candidiasis. According to the fungal colony counts, fungal burden in the vagina lavage dropped remarkably after treatment with Hst-5. Furthermore, cytological analysis of the lavage fluid indicated that the number of cast-off cells including cornified epithelial cells and inflammatory cells also decreased; histological evaluation of the vagina tissue revealed less fungi adhering to the vaginal wall in treated animals than in controls. Combined, these results suggested for the first time the potential utility of Hst-5 as a topical treatment for vulvovaginal candidiasis, uncovering the possibility of exploiting the natural antibiotic peptides in other aspects. © FEMS 2017.

    Invasive candidiasis is a major nosocomial fungal disease in the United States associated with high rates of illness and death. We analyzed inpatient hospitalization records from the Healthcare Cost and Utilization Project to estimate incidence of invasive candidiasis-associated hospitalizations in the United States. We extracted data for 33 states for 2002-2012 by using codes from the International Classification of Diseases, 9th Revision, Clinical Modification, for invasive candidiasis; we excluded neonatal cases. The overall age-adjusted average annual rate was 5.3 hospitalizations/100,000 population. Highest risk was for adults >65 years of age, particularly men. Median length of hospitalization was 21 days; 22% of patients died during hospitalization. Median unadjusted associated cost for inpatient care was $46,684. Age-adjusted annual rates decreased during 2005-2012 for men (annual change -3.9%) and women (annual change -4.5%) and across nearly all age groups. We report a high mortality rate and decreasing incidence of hospitalizations for this disease.

    In this prospective and monocentric study, we investigated the performance of a commercialized real-time polymerase chain reaction (RT-PCR) test system for the specific detection of DNA from Candida albicans, C. dubliniensis, C. glabrata, C. krusei, C. lusitaniae, C. parapsilosis, and C. tropicalis in human milk samples of patients suspicious of mammary candidiasis. For this purpose, 43 breast-feeding women with characteristic symptoms of mammary candidiasis and 40 asymptomatic controls were enrolled. By culture, Candida spp. were detected in 8.8 % (4/46) and 9.3 % (4/43) of patient and control samples, respectively. Candida albicans (2/46), C. parapsilosis (1/46), and C. guilliermondii (1/46) were present in patient samples, and C. lusitaniae (3/43) and C. guilliermondii (1/43) were present in the controls. After RT-PCR was applied, Candida spp. were found to be present in 67.4 % (31/46) and 79.1 % (34/43) of patient and control samples investigated, respectively. PCR detection of C. albicans and C. parapsilosis revealed only a low sensitivity and specificity of 67.4 % and 41.9 %, respectively. Our data do not support the use of Candida RT-PCR for sensitive and specific diagnosis of mammary candidiasis.

    Advancement of modern medicine, the increasing ratio of immunocompromised and immunosuppressive individuals is increased in hospitalized with serious underlying disease. This has resulted in a rise in the incidence of fungal infections, especially those due to Candida species. For many years the conventional antibiotic therapy has been critical in the fight against Candidiasis. Candidiasis is a fungal infection due to various types of Candida (yeast) species. In this study, zinc oxide nanoparticles (ZnONPs) were synthesized using the Cinnamomum verum bark plus Cassia auriculata leaf powder extracts. The characterization of synthesized ZnONPs was done by UV-Vis spectrophotometer and SEM analysis. The average size of nanoparticles was 77 nm. Synergistic anticandidal activity of ZnONPs (ZnONPs plus antibiotics) was determined by disc diffusion method against 16 multidrug resistant clinical pathogens of Candida species. Antibiotic Ketoconazole plus ZnONPs showed best synergistic anticandidal activity against all the 16 isolates. Green synthesized ZnONPs appears to be a new promising approach to fight against Candidiasis.

    Vaginal candidiasis or vulvovaginal candidiasis (VC) is a common mucosal infection of vagina, mainly caused by Candida species. The major symptoms of VC are dyspareunia, pruritis, itching, soreness, vagina as well as vulvar erythema and edema. Most common risk factors that lead to the imbalance in the vaginal micro biota are the use of antibiotics, pregnancy, diabetes mellitus, immuno suppression as in AIDS or HIV patients, frequent sexual intercourse, spermicide and intra-uterine devices and vaginal douching. Various anti-fungal drugs are available for effective treatment of VC. Different conventional vaginal formulations (creams, gels, suppositories, powder, ointment, etc.) for VC are available today but have limited efficacy because of lesser residence time on vaginal epithelium due to self-cleansing action of vagina. So to overcome this problem, an extended and intimate contact with vaginal mucosa is desired; which can be accomplished by utilizing mucoadhesive polymers. Mucoadhesive polymers have an excellent binding capacity to mucosal tissues for considerable period of time. This unique property of these polymers significantly enhances retention time of different formulations on mucosal tissues. Currently, various novel formulations such as liposomes, nano- and microparticles, micro-emulsions, bio-adhesive gel and tablets are used to control and treat VC. In this review, we focused on current status of vaginal candidiasis, conventional and nanotechnology inspired formulation approaches.

    The objective of the present investigation was formulation, optimization and characterization of mucoadhesive film of clotrimazole (CT) which is patient-convenient and provides an effective alternative for the treatment of vaginal candidiasis. CT is an antimycotic drug applied locally for the treatment of vaginal candidiasis. Mucoadhesive vaginal films were prepared by solvent casting technique using hydroxyl propylcellulose and sodium alginate as polymers. Propylene glycol and polyethylene glycol-400 were evaluated as plasticizers. The mucoadhesive vaginal films were evaluated for percentage elongation, tensile strength, folding endurance, drug content, in vitro disintegration time, in vitro dissolution study, swelling index, bioadhesive strength, and diffusion study. Among various permeation enhancers used, isopropyl myristate was found to be suitable. To evaluate the role of the concentration of permeation enhancer and concentration of polymers in the optimization of mucoadhesive vaginal film, 3(2) full factorial design was employed. Optimized batch showed in vitro disintegration time, 18 min; drug content, 99.83%; and tensile strength, 502.1 g/mm(2). In vitro diffusion study showed that 77% drug diffusion occurred in 6 h. This batch was further evaluated by scanning electron microscopy indicating uniformity of the film. In vitro Lactobacillus inhibition and in vitro antifungal activity of optimized batch showed an inhibitory effect against Candida albicans and no effect on Lactobacillus, which is a normal component of vaginal flora. Mucoadhesive vaginal film of CT is an effective dosage form for the treatment of vaginal candidiasis.

    to study vulvovaginal candidiasis from the vaginal fluid of women with and without clinical suspicion, identifying the frequency of Candida spp., and associating it with intrinsic and extrinsic risk factors. a total of 286 samples from patients attended in private practices and public health units from August 2005 to August 2007 were collected, being 121 women under clinical suspicion and 165, without. The samples were collected with sterile swabs, taken to the laboratory in 0.85% physiological solution, and then seeded in CHROMagar Candida and in 4% agar Sabourad with chloramphenicol. Classical identification procedures were carried out: macro and micromorphology, zymogram and auxanogram. Data obtained were analyzed by frequency tests and contingency tables (chi2). a total of 47.9% of the women under clinical suspicion got confirmation of candidiasis by the laboratorial tests. Among the patients without clinical suspicion (Control Group), 78.2% were vulvovaginal candidiasis negative according to the laboratorial tests. Candida albicans was the prevalent strain in 74.5% of the cases. There were significant differences among the positive cases, according to the patients from the two cities evaluated (pcandidiasis. Geographical localization has shown to be a relevant factor in the distribution of events. The type of clothing may be one of the reasons for it. Culture of samples from the vaginal contents, followed by microorganisms' identification, can be important.

    Th17 cells play a major role in coordinating the host defence in oropharyngeal candidiasis. In this study we investigated the involvement of the Th17 response in an animal model of vulvovaginal candidiasis (VVC). To monitor the course of infection we exploited a new in vivo imaging technique. i) The progression of VVC leads to a strong influx of neutrophils in the vagina soon after the challenge which persisted despite the resolution of infection; ii) IL-17, produced by vaginal cells, particularly CD4 T cells, was detected in the vaginal wash during the infection, reaching a maximum 14 days after the challenge; iii) The amount and kinetics of IL-23 in vaginal fluids were comparable to those in vaginal cells; iv) The inhibition of Th17 differentiation led to significant inhibition of IL-17 production with consequent exacerbation of infection; v) An increased production of βdefensin 2 was manifested in cells of infected mice. This production was strongly reduced when Th17 differentiation was inhibited and was increased by rIL-17 treatment. These results imply that IL-17 and Th17, along with innate antimicrobial factors, have a role in the immune response to vaginal candidiasis.

    Vulvovaginal candidiasis is known as one of the most common fungal infection among women of reproductive age and considered as an important public health problem. In recent years, due to resistance to common antifungal medication, the use of traditional medicine of anti-fungal and herbal treatment increased. Therefore the objective of this study was to determine the effects of vaginal cream, mixture of yogurt and honey and comparing it with clotrimazole vaginal cream on symptoms of Vulvovaginal candidiasis in patients. In this randomized, triple blind clinical trial of 70 non-pregnant women infected with Candidal vulvovaginitis were placed in two groups of Vaginal cream mixed of yogurt and honey recipients (N=35) and clotrimazole vaginal cream (N=35). Both groups were treated for 7 days. At the beginning of study, Clinical and laboratory signs and symptoms were registered 7 and 14 days after treatment by questionnaire, observation form and secretions culture results. Data by chi-square test, t test, McNemar tests were analyzed by SPSS version 21. Significance level of 0.05 was considered. The result of present study reveals the significant differences in symptom improvement of ' yogurt and honey, than clotrimazole group (P0.05) CONCLUSION: This study indicated that he therapeutic effects of vaginal cream, yogurt and honey is not only similar with clotrimazole vaginal cream but more effective in relieving some symptoms of vaginal candidiasis. Therefore, the use of this product can be suggested as an herbal remedy for candida infection treatment.

  13. Is there a role for antibody testing in the diagnosis of invasive candidiasis?

    During the last decades, the use of antibody tests for the diagnosis of invasive mycoses has declined as a consequence of the general belief that they are insensitive and non-specific. However, there is a clear evidence that antibodies can be detected in highly immunodeficient patients (such as bone marrow transplant recipients), and that those antibodies are useful for the diagnosis. Antibody tests are currently in use as diagnostic tools for some primary mycoses, such as the endemic mycoses, aspergilloma, allergic bronchopulmonary aspergilosis and sporothrichosis. For invasive candidiasis, diagnostic methods must differentiate Candida colonization of mucous membranes or superficial infection from tissue invasion by this microorganism. Substantial progress has been made in diagnosis of invasive candidiasis with the development of a variety of methods for the detection of antibodies and antigens. However, no single test has found widespread clinical use and there is a consensus that diagnosis based on a single specimen lacks sensitivity. It is necessary to test sequential samples taken while the patient is at greatest risk for developing invasive candidiasis to optimize the diagnosis. Results obtained from a panel of diagnostic tests in association with clinical aspects will likely be the most useful strategy for early diagnosis and therapy.

    Relevant reports about oral candidiasis status and prevention measures after free flap surgery for the oral and maxillofacial region are limited. The present study explored oral candidiasis status after free flap surgery and its prevention through a prospective comparative study. One hundred four patients were randomized to a control group (n = 54) and an experimental group (n = 50). Compared with the control group, the experimental group was provided an additional 3% sodium bicarbonate saline solution for oral care after free flap surgery. The incidence of oral candidiasis was evaluated by objective examination (saliva culture and salivary pH measurement) and subjective evaluation (clinical signs of oral candidiasis) at admission and from postoperative days 1 to 14. The salivary pH values of the 2 groups were lower than the normal salivary pH, and postoperative salivary pH values were always lower than the active range of oral lysozymes in the control group. The salivary pH values of the experimental group were higher than those of the control group from postoperative days 6 to 14 (P < .05). The incidence of oral candidiasis was 13.0% in the control group, which was higher than that in the experimental group (2.0%; P < .05). In addition, advanced age, use of a free flap for the simultaneous repair of intraoral and paraoral defects, and a combination of 2 antibiotic types were risk factors for oral candidiasis. Oral candidiasis was common in patients after free flap reconstruction surgery, and the use of 3% sodium bicarbonate saline solution for oral care effectively prevented it.

    Full Text Available Candidia esophagitis (CE is an AIDS-defining condition, usually occurring in individuals with low CD4 counts of <200 cells/µL. Endoscopy is a valuable definitive diagnostic method for CE but may not be indicated for asymptomatic patients or for those with high CD4 counts or without oral candidiasis. This study assessed such patients to clarify the factors associated with CE and its severity on endoscopy in the highly active antiretroviral therapy (HAART era.A total of 733 HIV-infected patients who underwent upper gastrointestinal (GI endoscopy were analyzed. Sexual behavior, CD4(+ count, HIV-RNA viral load (VL, history of HAART, GI symptoms, GI diseases, and oral candidiasis were assessed. Endoscopic severity of CE was classified as mild (Kodsi's grade I/II or severe (grade III/IV. Of the 733 subjects, 62 (8.46% were diagnosed with CE (mild, n = 33; severe, n = 29. Of them, 56.5% (35/62 had no GI symptoms, 30.6% (19/62 had CD4 + ≥200 cells/μL, and 55.3% (21/38 had no oral candidiasis. Univariate analysis found lower CD4+ counts, higher HIV VL, and no history of HAART to be significantly associated with CE. With lower CD4(+ counts and higher HIV VL, CE occurrence increased significantly (P<0.01 for trend in odds. Multivariate analysis showed low CD4+ counts and high HIV VL to be independently associated with CE. Of the severe CE patients, 55.2% (16/29 had no GI symptoms and 44.4% (8/18 had no oral candidiasis. Median CD4(+ counts in severe cases were significantly lower than in mild cases (27 vs. 80; P = 0.04.Low CD4+ counts and high HIV VL were found to be factors associated with CE, and advanced immunosuppression was associated with the development of severity. Endoscopy is useful as it can detect CE, even severe CE, in patients without GI symptoms, those with high CD4 counts, and those without oral candidiasis.

    Oral candidiasis which is the most common type of Candida infections affecting humans, is most frequently caused by C.albicans. Immune response of the host, as well as a variety of virulence factors of the causative agent, play important roles in the development of Candida infections. The colonization rate of Candida in the oral cavity of healthy individuals, is between 25-30%, however, this rate is reported to be increased in immunosuppressive subjects. In our study, we established an oral candidiasis model with C.albicans in healthy and experimentally immunocompromised mice and aimed to compare Candida colonization rates and histopathological changes occurred in the tongue and esophagus tissues of the animal groups. A total of 21 BALB/c mice were grouped as control (Group 1; n= 7), healthy (Group 2; n= 7) and immunocompromised (Group 3; n= 7) groups. Immunosuppression in mice was performed by subcutaneous injection of prednisolone. For experimental oral candidiasis, cotton swab impregnated with C.albicans strains which did not have acid proteinase and phospholipase enzyme activity, no biofilm production, and sensitive to fluconazole and amphotericin B, were used. In the control group, physiological saline solution was used instead of C.albicans strain. In the forth day of experimental oral candidiasis model swab samples taken from the dorsal tongue surface of mice were evaluated by quantitative cultivation method. No yeast colonies were detected in Group 1 while more significant number of yeast colonies were observed in Group 3 compared to Group 2 (p= 0.002). Tongue and esophagus tissues of mice were stained with hematoxylin-eosin and periodic acid schiff staining and evaluated in terms of inflammatory response, abscess formation, vascular congestion, vasodilation and for the presence of yeast and hyphae. When the inflammation in esophagus was considered, statistically significant difference was determined between group 1 and group 3 (p= 0.023), however, no

    Full Text Available Introduction: Oral candidiasis is an opportunistic infection that is readily detectable in the clinic. It has been used to assess the immune status of HIV patients as well as the effectiveness of highly active antiretroviral therapy. Objective: To determine the frequency of oral candidiasis infection among various indicators associated with antiretroviral therapy effectiveness. Material and methods: Cross-sectional and analytical study, in which groups were initially created based on the use or not of antiretroviral therapy. Participants were subjected to questions on factors related to Candida infection, salivary flow measurements and a clinical examination of the oral cavity to determine the frequency of candidiasis Results: The difference in the frequency of oral candidiasis between groups with and without antiretroviral therapy was significant (OR 2.6 IC95% 1.5-4.4. There were also a significant association with decreased number of CD4 lymphocytes.. Discussion: Resistance to anti-retroviral therapy constitutes one of the fundamental barriers to a successful treatment in patients infected with the human immunodeficiency virus, as do toxicities and adherence problems. Clinical markers such oral candidiasis is an easily and accesible parameter for the early detection of treatment failure.

    To investigate the clinical features of invasive candidiasis in children and the risk factors for Candida bloodstream infection. A retrospective study was performed on 134 children with invasive candidiasis and hospitalized in 5 tertiary hospitals in Urumqi, China, between January 2010 and December 2015. The Candida species distribution was investigated. The clinical data were compared between the patients with and without Candida bloodstream infection. The risk factors for Candida bloodstream infection were investigated using multivariate logistic regression analysis. A total of 134 Candida strains were isolated from 134 children with invasive candidiasis, and non-albicans Candida (NAC) accounted for 53.0%. The incidence of invasive candidiasis in the PICU and other pediatric wards were 41.8% and 48.5% respectively. Sixty-eight patients (50.7%) had Candida bloodstream infection, and 45 patients (33.6%) had Candida urinary tract infection. There were significant differences in age, rate of use of broad-spectrum antibiotics, and incidence rates of chronic renal insufficiency, heart failure, urinary catheterization, and NAC infection between the patients with and without Candida bloodstream infection (Pcandidiasis is similar between the PICU and other pediatric wards. NAC is the most common species of invasive candidiasis. Candida bloodstream infection is the most common invasive infection. Younger age (1-24 months) and NAC infection are the risk factors for Candida bloodstream infection.

    To compare the prevalence of asymptomatic oral candidal carriage in healthy volunteers with human immunodeficiency virus (HIV)-positive patients in China, as well as to investigate the relationship between CD4+ lymphocyte count and oral candidal colonization or oral candidiasis. Oral candidal carriage and oral candidiasis were investigated in 101 patients with HIV-infection seen at Youan Hospital, Beijing, China. Two hundred and seventeen healthy volunteers were involved as a control. Culture from saliva was used to test for the presence of oral Candida. CD4+ lymphocyte count was measured by flow cytometry. All data were analyzed statistically by SAS. Asymptomatic oral candidal carriage rate (28.6%) in HIV-positive group was similar to that in the healthy group (18.0%; P = 0.07). No significant difference in CD4+ lymphocyte count was found between oral Candida carriers and non-carriers among HIV-positive subjects (P = 0.89). However, the frequency of oral candidiasis increased with the decrease in CD4+ lymphocyte count (P < 0.0001), and pseudomembranous candidiasis was predominant in HIV-positive patients with CD4+ <200 cells microl(-1) (66.7%). In HIV-positive subjects, asymptomatic oral candidal colonization is not related to CD4+ lymphocyte count of blood, and the carriage rate is similar to that in the healthy population. Oral candidiasis is more likely to be observed in HIV-positive patients who have a low CD4+ lymphocyte count.

    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)

    The regular colonisation of the oesophagus with a Candida species can, after oesophageal perforation, result in a contamination of the mediastinum and the pleura with a Candida species. A patient cohort of 80 patients with oesophageal perforation between 1986 and 2010 was analysed retrospectively. The most common sources with positive results for Candida were mediastinal biopsies and broncho-alveolar secretions. Candida species were detected in 30% of the patients. The mortality rate was 41% in patients with positive microbiology results for Candida, whereas it was 23% in the remaining patient cohort. This difference did not reach statistical significance (P = 0.124). Mortality associated with oesophageal perforation was attributed mainly to septic complications, such as mediastinitis and severe pneumonia. During the study period we observed a shift towards non-albicans species that were less susceptible or resistant to fluconazole. In selected patients with risk factors as immunosuppression, granulocytopenia and long-term intensive-care treatment together with the finding of Candida, an antimycotic therapy should be started. A surgical approach offers the possibility to obtain deep tissue biopsies. The antimycotic therapy should start with an echinocandin, as the resistance to fluconazole is growing and to cover non-albicans Candida species, too. © 2012 Blackwell Verlag GmbH.

    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.

    Recognition that ascending infection leads to preterm birth has led to a number of studies that have evaluated the treatment of vaginal infections in pregnancy to reduce preterm birth rates. However, the role of candidiasis is relatively unexplored. Our aim was to undertake a systematic review and meta-analysis to assess whether treatment of pregnant women with vulvovaginal candidiasis reduces preterm birth rates and other adverse birth outcomes. We undertook a systematic review and meta-analysis of published randomised controlled trials (RCTs) in which pregnant women were treated for vulvovaginal candidiasis (compared to placebo or no treatment) and where preterm birth was reported as an outcome. Trials were identified by searching the Cochrane Central Register of Controlled Trials, Medline and Embase databases to January 2014. Trial eligibility and outcomes were pre-specified. Two reviewers independently assessed the studies against the agreed criteria and extracted relevant data using a standard data extraction form. Meta-analysis was used to calculate pooled rate ratios (RR) and 95% confidence intervals (CI) using a fixed-effects model. There were two eligible RCTs both among women with asymptomatic candidiasis, with a total of 685 women randomised. Both trials compared treatment with usual care (no screening for, or treatment of, asymptomatic candidiasis). Data from one trial involved a post-hoc subgroup analysis (n = 586) of a larger trial of treatment of 4,429 women with asymptomatic infections in pregnancy and the other was a pilot study (n = 99). There was a significant reduction in spontaneous preterm births in treated compared with untreated women (meta-analysis RR = 0.36, 95% CI = 0.17 to 0.75). Other outcomes were reported by one or neither trial. This systematic review found two trials comparing the treatment of asymptomatic vaginal candidiasis in pregnancy for the outcome of preterm birth. Although the effect estimate suggests that

    The response rate among 58 patients with cancer and candidemia or deep-seated candidiasis treated with micafungin monotherapy was 81%. Intensive care unit (ICU) stay, concomitant nonfungal infections, and acute kidney injury were significantly associated with the 30-day crude mortality rate. Severe neutropenia was an independent predictor of micafungin failure. The efficacy and safety of micafungin in cancer patients with invasive candidiasis were comparable to those reported for patients without malignancy and for cancer patients treated with caspofungin.

    Objective: To explore a simple, rapid and efficient method for the diagnosis of oral candidiasis in clinical practice. Methods: Totally 124 consecutive patients with suspected oral candidiasis were enrolled from Department of Oral Medicine, Peking University School and Hospital of Stomatology, Beijing, China. Exfoliated cells of oral mucosa and saliva or concentrated oral rinse) obtained from all participants were tested by three rapid smear methods(10% KOH smear, gram-stained smear, Congo red stained smear). The diagnostic efficacy(sensitivity, specificity, Youden's index, likelihood ratio, consistency, predictive value and area under curve(AUC) of each of the above mentioned three methods was assessed by comparing the results with the gold standard(combination of clinical diagnosis, laboratory diagnosis and expert opinion). Results: Gram-stained smear of saliva(or concentrated oral rinse) demonstrated highest sensitivity(82.3%). Test of 10%KOH smear of exfoliated cells showed highest specificity(93.5%). Congo red stained smear of saliva(or concentrated oral rinse) displayed highest diagnostic efficacy(79.0% sensitivity, 80.6% specificity, 0.60 Youden's index, 4.08 positive likelihood ratio, 0.26 negative likelihood ratio, 80% consistency, 80.3% positive predictive value, 79.4% negative predictive value and 0.80 AUC). Conclusions: Test of Congo red stained smear of saliva(or concentrated oral rinse) could be used as a point-of-care tool for the rapid diagnosis of oral candidiasis in clinical practice.

    To systematically review and assess the efficacy, different treatment protocols (formulation, dosage, and duration), and safety of nystatin for treating oral candidiasis. Four electronic databases were searched for trials published in English till July 1, 2015. Randomized controlled trials comparing nystatin with other antifungal therapies or a placebo were included. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis or descriptive study on the efficacy, treatment protocols, and safety of nystatin was conducted. The meta-analysis showed that nystatin pastille was significantly superior to placebo in treating denture stomatitis. Nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. The descriptive investigations showed that administration of nystatin suspension and pastilles in combination for 2 weeks might achieve a higher clinical and mycological cure rate, and using the nystatin pastilles alone might have a higher mycological cure rate, when compared with using nystatin suspensions alone. Nystatin pastilles at a dose of 400,000 IU resulted in a significantly higher mycological cure rate than that administrated at a dose of 200,000 IU. Furthermore, treatment with nystatin pastilles for 4 weeks seemed to have better clinical efficacy than treatment for 2 weeks. Descriptive safety assessment showed that poor taste and gastrointestinal adverse reaction are the most common adverse effects of nystatin. Nystatin pastille was significantly superior to placebo in treating denture stomatitis, while nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. Indirect evidence from a descriptive study demonstrated that administration of nystatin pastille alone or pastille and suspension in combination is more effective than that of suspension alone; prolonged treatment duration for up to 4 weeks can increase the

    Previously we showed that antibodies specific for the glycan β-1,2-mannotriose [β-(Man)3] on the cell surface of Candida albicans protect mice against disseminated candidiasis (H. Xin, S. Dziadek, D. R. Bundle, and J. E. Cutler, Proc. Natl. Acad. Sci. U. S. A. 105:13526–13531, 2008). Furthermore, six 14-mer peptides that are within the N-terminal portion of C. albicans wall proteins were conjugated to the glycan in an attempt to create immunogenic glycopeptide conjugates. By a dendritic cell (DC)-based immunization approach, all were immunogenic and three of the six conjugates induced a high degree of protection in mice. Interestingly, whereas all six peptides induced antibody responses when used alone to pulse DCs for subsequent immunizations, three peptides induced protection, and one in particular, peptide Fba (derived from fructose-bisphosphate aldolase), induced robust protective responses and is the focus of the current work. Fba peptide is not restricted by the major histocompatibility complex class II (MHC-II), as it induced anti-Fba antibodies in mice of different H-2 haplotypes and in rabbits. Furthermore, the peptide induced protection against disease caused by different C. albicans strains. Partial protection was achieved when alum was used in place of DCs for Fba immunizations. The passive transfer of immune sera from Fba-vaccinated mice, but not immune serum preabsorbed with fungal cells, conferred protection in naïve mice. This result, along with our finding that a monoclonal antibody specific for the peptide, E2-9 (IgM), protected mice against candidiasis, provide strong evidence that antibodies contribute to protection. Our work demonstrates the utility of cell wall peptides alone or as glycopeptides in vaccines designed for the induction of immunity against candidiasis and monoclonal antibodies as a rapid immunoprotective approach against the disease.

    The aim of this work was the development and characterization of nisin-loaded nanoparticles and the evaluation of its potential antifungal activity. Candidiasis is a fungal infection caused by Candida sp. considered as one of the major public health problem currently. The discovery of antifungal agents that present a reduced or null resistance of Candida sp. and the development of more efficient drug release mechanisms are necessary for the improvement of candidiasis treatment. Nisin, a bacteriocin commercially available for more than 50 years, exhibits antibacterial action in food products with potential antifungal activity. Among several alternatives used to modulate antifungal activity of bacteriocins, polymeric nanoparticles have received great attention due to an effective drug release control and reduction of therapeutic dose, besides the minimization of adverse effects by the preferential accumulation in specific tissues. The nisin nanoparticles were prepared by double emulsification and solvent evaporation methods. Nanoparticles were characterized by dynamic light scattering, zeta potential, Fourier transform infrared, X-ray diffraction, differential scanning calorimetry, and scanning electron microscopy. Antifungal activity was accessed by pour plate method and cell counting using Candida albicans strains. The in vitro release profile and in vitro permeation studies were performed using dialysis bag method and pig vaginal mucosa in Franz diffusion cell, respectively. The results revealed nisin nanoparticles (300 nm) with spherical shape and high loading efficiency (93.88 ± 3.26%). In vitro test results suggest a promising application of these nanosystems as a prophylactic agent in recurrent vulvovaginal candidiasis and other gynecological diseases.

    In this article, we discuss the development of methods for computer-aided jaw surgery, which allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3-dimensional surface models from cone-beam computed tomography, dynamic cephalometry, semiautomatic mirroring, interactive cutting of bone, and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intraoperative guidance. The system provides further intraoperative assistance with a computer display showing jaw positions and 3-dimensional positioning guides updated in real time during the surgical procedure. The computer-aided surgery system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training, and assessing the difficulties of the surgical procedures before the surgery. Computer-aided surgery can make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases. 2010 American Association of Orthodontists.

    Fungal infections are as a cause of morbidity and mortality in immunocompromise patients. Because the respiratory tract is colonized with Candida, the presence of this agent in respiratory specimens makes the diagnosis of Candida pneumonia problematic. Candida pneumonia is a rare infection, and the majority of cases are secondary to hematogenous dissemination. Furthermore isolated Candida pneumonia originating from endotracheal inoculation is an extremely rare entity. We describe a case of isolated pulmonary candidiasis in the form multiple nodular lesions in a patient with long-term history of diabetes mellitus without evidence of fungemia or systemic involvement who responded to antifungal therapy.

Randomized controlled trials comparing nystatin with other antifungal therapies or a placebo were included. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis or descriptive study on the efficacy, treatment protocols, and safety of nystatin was conducted.Results: The meta-analysis showed that nystatin pastille was significantly superior to placebo in treating denture stomatitis. Nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. The descriptive investigations showed that administration of nystatin suspension and pastilles in combination for 2 weeks might achieve a higher clinical and mycological cure rate, and using the nystatin pastilles alone might have a higher mycological cure rate, when compared with using nystatin suspensions alone. Nystatin pastilles at a dose of 400,000 IU resulted in a significantly higher mycological cure rate than that administrated at a dose of 200,000 IU. Furthermore, treatment with nystatin pastilles for 4 weeks seemed to have better clinical efficacy than treatment for 2 weeks. Descriptive safety assessment showed that poor taste and gastrointestinal adverse reaction are the most common adverse effects of nystatin.Conclusion: Nystatin pastille was significantly superior to placebo in treating denture stomatitis, while nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients.

    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.

    Full Text Available Deep Candida infections commonly occur in immunosuppressed patients. A rare case of a multiple deep organ infection with Candida albicans and spinal tuberculosis was reported in a healthy young man. The 19-year-old man complained of month-long fever and lower back pain. He also had a history of scalded mouth syndrome. Coinfection with Mycobacterium tuberculosis and Candida albicans was diagnosed using the culture of aspirates from different regions. Symptoms improved considerably after antifungal and antituberculous therapy. This case illustrates that infection with tuberculosis might impair the host's immune system and increase the risk of invasive candidiasis in an immunocompetent patient.

    Candida albicans has a variety of virulence factors, including secreted aspartyl proteases, which are determinant factors in the pathogenesis of this yeast in immunocompromised patients. Proteinase activity was identified in C. albicans strains isolated from the oral cavity of immunocompromised patients with cancer, diabetes and HIV+, with oral candidiasis and in healthy subjects. Two hundred and fifty C. albicans strains were analyzed, distributed in 5 different groups: patients with cancer, diabetes, HIV+, with oral candidiasis and healthy subjects. Proteolytic activity was identified in 46% of the strains from cancer patients, 54% from HIV+ patients, 60% from diabetics, 70% from oral candidiasis patients, and 42% from healthy subjects. Activity was higher in strains from immunocompromised and oral candidiasis patients than in healthy subjects. Differences were observed between the candidiasis-healthy, candidiasis-HIV+, and diabetic-healthy groups. No differences were observed between the oral candidiasis, diabetes and cancer patients, between the diabetes and HIV+ patients, or between the cancer patients, HIV+ patients and healthy subjects. The present results suggest that although secreted aspartyl proteases are important in the pathogenesis of C. albicans, their activity depends on host conditions.

    Oral candidiasis is often accompanied by severe inflammation, resulting in a decline in the quality of life of immunosuppressed individuals and elderly people. To develop a new oral therapeutic option for candidiasis, a nonpathogenic commensal oral probiotic microorganism, Streptococcus salivarius K12, was evaluated for its ability to modulate Candida albicans growth in vitro, and its therapeutic activity in an experimental oral candidiasis model was tested. In vitro inhibition of mycelial growth of C. albicans was determined by plate assay and fluorescence microscopy. Addition of S. salivarius K12 to modified RPMI 1640 culture medium inhibited the adherence of C. albicans to the plastic petri dish in a dose-dependent manner. Preculture of S. salivarius K12 potentiated its inhibitory activity for adherence of C. albicans. Interestingly, S. salivarius K12 was not directly fungicidal but appeared to inhibit Candida adhesion to the substratum by preferentially binding to hyphae rather than yeast. To determine the potentially anti-infective attributes of S. salivarius K12 in oral candidiasis, the probiotic was administered to mice with orally induced candidiasis. Oral treatment with S. salivarius K12 significantly protected the mice from severe candidiasis. These findings suggest that S. salivarius K12 may inhibit the process of invasion of C. albicans into mucous surfaces or its adhesion to denture acrylic resins by mechanisms not associated with the antimicrobial activity of the bacteriocin. S. salivarius K12 may be useful as a probiotic as a protective tool for oral care, especially with regard to candidiasis.

    This study aims to determine the incidence, trends of systemic candidiasis and meningitis in extremely low birthweight (ELBW) neonates (candidiasis and meningitis over an 11-year period (1997 to 2007). Matched case control analyses were performed to determine the risk factors and comorbidities which were severe intraventricular haemorrhage (IVH), severe retinopathy of prematurity (ROP), patent ductus arteriosus (PDA) requiring treatment, necrotising enterocolitis (NEC), chronic lung disease (CLD) and cholestatic jaundice. Mortality and end organ involvement secondary to systemic candidiasis were identified as adverse outcomes. Of the 757 ELBW neonates, 51 (6.7%) had evidence of systemic candidiasis with a significant 3-fold increase in trend noted in 2007 as compared against 1997 (12.1% vs 3.8%) (RR 1.2, 95% CI, 1.06 to 1.36, P candidiasis (0% in 1997 vs 7.1% in 2007, RR 1.40, 95% CI, 1.04 to 1.25, P = 0.005). On logistic regression analysis, decreasing gestational age was an independent risk factor for systemic candidiasis (OR 2.0, 95% CI, 1.52 to 2.63, P candidiasis despite routine use of topical miconazole prophylaxis is of concern and future studies comparing the use of systemic fl uconazole versus oral nystatin may need to be considered.

    Oropharyngeal candidiasis (OPC, thrush) is an opportunistic infection caused by the commensal fungus Candida albicans. An understanding of immunity to Candida has recently begun to unfold with the identification of fungal pattern-recognition receptors such as C-type lectin receptors, which trigger protective T-helper (Th)17 responses in the mucosa. Hyper-IgE syndrome (HIES/Job's syndrome) is a rare congenital immunodeficiency characterized by dominant-negative mutations in signal transducer and activator of transcription 3, which is downstream of the Th17-inductive cytokines interleukin (IL)-6 and IL-23, and hence patients with HIES exhibit dramatic Th17 deficits. HIES patients develop oral and mucocutaneous candidiasis, supporting a protective role for Th17 cells in immunity to OPC. However, the Th17-dependent mechanisms of antifungal immunity in OPC are still poorly defined. An often unappreciated aspect of oral immunity is saliva, which is rich in antimicrobial proteins (AMPs) and exerts direct antifungal activity. In this study, we show that HIES patients show significant impairment in salivary AMPs, including β-defensin 2 and Histatins. This tightly correlates with reduced candidacidal activity of saliva and concomitantly elevated colonization with Candida. Moreover, IL-17 induces histatins in cultured salivary gland cells. This is the first demonstration that HIES is associated with defective salivary activity, and provides a mechanism for the severe susceptibility of these patients to OPC.

    2015-01-01

    Oral candidiasis may be manifested in the oral cavity as either mild or severe oral fungal infection. This infection results from the overgrowth of Candida species normally existing in the oral cavity in minute amounts based on many predisposing factors. Several aspects have spurred the search for new strategies in the treatment of oral candidiasis, among which are the limited numbers of new antifungal drugs developed in recent years. Previous studies have shown that thyme and clove oils have antimycotic activities and have suggested their incorporation into pharmaceutical preparations. This study aimed to investigate the possibility of the incorporation and characterization of essential oils or their extracted active ingredients in Orabase formulations. Orabase loaded with clove oil, thyme oil, eugenol, and thymol were prepared and evaluated for their antifungal activities, pH, viscosity, erosion and water uptake characteristics, mechanical properties, in vitro release behavior, and ex vivo mucoadhesion properties. All prepared bases showed considerable antifungal activity and acceptable physical characteristics. The release pattern from loaded bases was considerably slow for all oils and active ingredients. All bases showed appreciable adhesion in the in vitro and ex vivo studies. The incorporation of essential oils in Orabase could help in future drug delivery design, with promising outcomes on patients' well-being.

    Candida albicans is a minor component of the oral microbiota and an opportunistic pathogen that takes advantage of the immunocompromised host and causes oral mucositis and oral candidiasis. This organism is able to undergo phenotypic modification from a yeast to hyphae growth phase, one of the key arsenals for immune cell evasion, tissue invasion and biofilm formation. The latter property coupled with overgrowth and immune compromising factors such as HIV/AIDS, cancer treatments, organ transplantation, diabetes, corticosteroid use, dentures, and broad-spectrum antibiotic use have modified the fungus from a normal component of the microflora to a foe of an oral cavity and resulting in reduced sensitivity towards commonly utilised antifungal agents. Hence, the need for alternative therapy to curb this plight is of importance. Making use of biomolecules produced by Streptococcus mutans, application of lactoferrin which is a nonspecific host defense factor found in saliva with metal chelating and broader antimicrobial properties, use of probiotics which have the capacity to boost the host immunity through eliciting Immunoglobulin A synthesis, and perturbing the pathogen's environment via competition of space and food, and application of photodynamic therapy can help to manage the burden of oral candidiasis.

    2016-01-01

    Oral candidiasis is a mycosis on the mucous membranes of the mouth but not limited to the mouth. Nystatin is one of the most frequently employed antifungal agents to treat infections and may be safely given orally as well as applied topically but its absorption through mucocutaneous membranes such as the gut and the skin is minimal. The purpose of this study is to enhance the effectiveness of nystatin using particulate system such as beads, micro- and nanoparticles of alginate incorporated into toothpaste. Those particulate systems of nystatin were prepared by extrusion/external gelation for beads and emulsification/internal gelation for micro- and nanoparticles and characterized. Small, anionic charged and monodispersed particles were successfully produced. The type of particulate system influenced all previous parameters, being microparticles the most suitable particulate system of nystatin showing the slowest release, the highest inhibitory effect of Candida albicans over a period of one year. Those results allowed the conclusion that alginate exhibits properties that enable the in vitro functionality of encapsulated nystatin and thus may provide the basis for new successful approaches for the treatment of oral antifungal infections such as oral candidiasis.

    The object of the study was to evaluate the efficacy of peroral administration of Fluconazole (Fungolon caps. 50 mg - "Actavis") in dose 150 mg (3 caps. x 50 mg) once weekly for a period of 6 months. 50 female patients of reproductive age with chronic vulvovaginal candidiasis caused by C. albicans with three or more recurrences per year were enrolled in an open trial prospective study and 42 women were evaluated before and after treatment. Clinical improvement was observed in 81% of the patients after treatment Microbiological cure was observed in 86% of the patients (36/42). Positive cultures for C. albicans after treatment had 6 patients. Four of these 6 patients had duration of the chronic candidiasis for more than 3 years. Side effects during the treatment were not significant and might not be directly correlated with the administration of fluconazole. There was no cessation of therapy due to side effects. 53.3% of the patients accepted positively the long duration of therapy while 30% found the long duration of treatment a major inconvenience. Fluconazole is easily administrated well tolerated and is suitable for the long treatment of chronic vulvovaginal candididasis.

    Purpose Esophageal candidiasis (EC) is the most frequent opportunistic fungal infection in immunocompromised host. However, we have found EC in healthy individuals through esophagogastroduodenoscopy (EGD). The aim of this study was to determine the prevalence and risk factors for EC in healthy individuals. Materials and Methods We retrospectively reviewed the medical records of 281 patients who had been incidentally diagnosed with EC. We also conducted age and sex matched case control study to identify the risk factor for EC. Results The prevalence of EC was 0.32% (281/88125). The most common coexisting EGD finding was reflux esophagitis (49/281, 17.4%). An antifungal agent was prescribed in about half of EC, 139 cases (49.5%). Follow-up EGD was undertaken in 83 cases (29.5%) and 20 cases of candidiasis was persistently found. Case control study revealed EC were more often found in user of antibiotics (p=0.015), corticosteroids (p=0.002) and herb medication (p=0.006) as well as heavy drinking (pantibiotics, corticosteroids and herb as well as heavy drinking were significant risk factors for EC in healthy individuals.

    High prevalence of topical fungal infections is perceived in majority of nations worldwide accounting for numerous serious systemic complications. Of several fungal infections, candidiasis is one of the widespread infections which is manifested due to localisation and proliferation of fungi. Present pharmacotherapy offers an effective treatment but possesses serious limitations like inadequate solubility, ineffectiveness in lowering diseased condition and patient incompliance. Several attempts to overcome these shortcomings and building suitable technology platforms for development of appropriate dosage forms which can enhance effectiveness, patient acceptability while maintaining safety, efficacy and affordability of drug delivery, have been made. Present review highlights on different types of fungal infections, its aetiology, pathophysiology, epidemiology and conventional formulations used. It also emphasises on applications of several novel approaches of anti-fungal drugs demonstrating advantages and limitations. Details regarding patterns of drug release and its site specificity with better patient compliance have been focussed. Etiology and pathogenesis of candidiasis should be understood clearly. Mentioned novel dosage forms should be explored to enhance therapeutic efficacy, subsequently investigating marketability and patentability. Nanoparticles seem to be a promising approach befitting all requirements.

    Invasive candidiasis continues to be associated with significant morbidity and mortality as well as substantial health care costs nationally and globally. One of the contributing factors is the development of resistance to antifungal agents that are already in clinical use. Moreover, there are known treatment limitations with all of the available antifungal agents. Since traditional techniques in novel drug discovery are time consuming, high-throughput screening using flow cytometry presents as a potential tool to identify new antifungal agents that would be useful in the management of these patients. Areas covered: In this review, the authors discuss the use of automated high-throughput screening assays based upon flow cytometry to identify potential antifungals from a library comprised of a large number of bioactive compounds. They also review studies that employed the use of this research methodology that has identified compounds with antifungal activity. Expert opinion: High-throughput screening using flow cytometry has substantially decreased the processing time necessary for screening thousands of compounds, and has helped enhance our understanding of fungal pathogenesis. Indeed, the authors see this technology as a powerful tool to help scientists identify new antifungal agents that can be added to the clinician's arsenal in their fight against invasive candidiasis.

    Pregnancy represents a risk factor in the occurrence of vaginal candidiasis. To determine the prevalence and clinical features associated with abnormal vaginal discharge and C. albicans infection in pregnant women. High vaginal swab samples and data on epidemiological characteristics were collected from 400 pregnant women with complaints of abnormal vaginal discharge at booking clinic of University of Maiduguri Teaching Hospital. The data was analysed using SPSS 16.0 statistical software. The prevalence of abnormal vaginal discharge in pregnancy was 31.5%. The frequency of abnormal vaginal discharge was 183 (45.8%) among those aged 20-24 years, 291 (72.8%) in multipara, 223 (55.8%) in those with Primary education and 293 (73.2%) in unemployed. Vulval pruritus 300 (75.0%) was significantly related to abnormal vaginal discharge (P candidiasis were 151 (50.3%), 14 (56.0%) and 75 (75.0%) respectively (P vaginal discharge in pregnancy was high in this study and C. albicans was the commonest cause. It is recommended that a pregnant woman complaining of abnormal vaginal discharge be assessed and Laboratory diagnosis done in order to give appropriate treatment.

    Background: It has been suggested that vaginal lactobacilli may reduce the risk of vulvovaginal candidiasis (VVC), but supporting data are limited. Our objective was to determine the relationship between vaginal bacterial flora and VVC. Methods: We conducted a prospective cohort analysis among 151 Kenyan sex workers. At monthly follow-up, VVC was defined as the presence of yeast buds, pseudohyphae, or both on vaginal wet preparation or KOH preparation. Generalized estimating equations were used to identify correlates of VVC. Results: Participants returned for a median of 12 (interquartile range 11-12) visits. Vulvovaginal candidiasis was present at 162 visits, including 26 with symptomatic VVC. Bacterial vaginosis (BV) was associated with fewer episodes of VVC (adjusted odds ratio [aOR] 0.29, 95% confidence interval [CI] 0.16-0.50). After excluding women with concurrent BV, another possible cause of vaginal symptoms, the likelihood of symptomatic VVC was higher in those with yeast on vaginal wet preparation in the past 60 days (aOR 4.06, 95% CI 1.12-14.74) and those with concurrent vaginal Lactobacillus colonization (aOR 3.75, 95% CI 1.30-10.83). Conclusions: Contrary to a commonly posed hypothesis of a protective effect, we found that vaginal Lactobacillus colonization was associated with a >4-fold increase in the likelihood of symptomatic VVC.

    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.

    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-β-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.

    Full Text Available Background. Vulvovaginal candidiasis is a common infection. The aim of this study was to identify the species of vaginal Candida isolates by using multiplex PCR technique. Methods. 191 isolates from patients admitted to Mahdieh hospital were identified. The vaginal swab specimens were cultured on Sabouraud Dextrose Agar. The ITS1 region between the 18S and 5.8S rRNA genes and a specific DNA fragment within the ITS2 region were amplified. The multiplex PCR products were separated by electrophoresis in 2% agarose gel, visualized by staining with ethidium bromide, and photographed. Descriptive statistics, Chi-square test, and Spearman correlation were used to summarize the findings. Results. C. albicans and C. glabrata were the most common species isolated from the specimens. A mix of C. glabrata and C. albicans was the most common mixed infection isolated from the samples. The analysis revealed a significant positive association between older age and infection with C. glabrata isolates (Spearman’s rho = 0.89, P=0.015. Conclusion. Multiplex PCR is a fast, yet reliable method to identify Candida species. C. albicans and then C. glabrata are the two most common causes of vulvovaginal candidiasis. The number of mixed fungal infections is higher among Iranian population compared to international reports.

    Invasive candidiasis is a major nosocomial fungal disease in the United States associated with high rates of illness and death. We analyzed inpatient hospitalization records from the Healthcare Cost and Utilization Project to estimate incidence of invasive candidiasis–associated hospitalizations in the United States. We extracted data for 33 states for 2002–2012 by using codes from the International Classification of Diseases, 9th Revision, Clinical Modification, for invasive candidiasis; we excluded neonatal cases. The overall age-adjusted average annual rate was 5.3 hospitalizations/100,000 population. Highest risk was for adults >65 years of age, particularly men. Median length of hospitalization was 21 days; 22% of patients died during hospitalization. Median unadjusted associated cost for inpatient care was $46,684. Age-adjusted annual rates decreased during 2005–2012 for men (annual change –3.9%) and women (annual change –4.5%) and across nearly all age groups. We report a high mortality rate and decreasing incidence of hospitalizations for this disease. PMID:27983497

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

    N. Chami

    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.

    Pathogenic mechanisms of Candida glabrata in oral candidiasis, especially because of its inability to form hyphae, are understudied. Since both Candida albicans and C. glabrata are frequently co-isolated in oropharyngeal candidiasis (OPC), we examined their co-adhesion in vitro and observed adhesion of C. glabrata only to C. albicans hyphae microscopically. Mice were infected sublingually with C. albicans or C. glabrata individually, or with both species concurrently, to study their ability to cause OPC. Infection with C. glabrata alone resulted in negligible infection of tongues; however, colonization by C. glabrata was increased by co-infection or a pre-established infection with C. albicans. Furthermore, C. glabrata required C. albicans for colonization of tongues, since decreasing C. albicans burden with fluconazole also reduced C. glabrata. C. albicans hyphal wall adhesins Als1 and Als3 were important for in vitro adhesion of C. glabrata and to establish OPC. C. glabrata cell wall protein coding genes EPA8, EPA19, AWP2, AWP7, and CAGL0F00181 were implicated in mediating adhesion to C. albicans hyphae and remarkably, their expression was induced by incubation with germinated C. albicans. Thus, we found a near essential requirement for the presence of C. albicans for both initial colonization and establishment of OPC infection by C. glabrata.

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

    Full Text Available Diabetes Mellitus (DM is a metabolic disease which is characterized by increased blood glucose level and also increased salivary glucose level. The disease is characterized by decreasing pH of the saliva. The decrease pH of saliva can the high risk of oral infection. Candidiasis is the most common infection of patients with diabetes mellitus. The purpose of this study was to determine the relationship between salivary glucose level and salivary pH to the occurrence of oral candidiasis in patients with DM. This type of research is analytic observational study on 30 sample with diabetes mellitus. The determination of salivary glucose level with “GOD PAP test enzymatic calorimetric” and salivary pH with lacmus paper. Oral candidiasis was determined in presenting candida albicans with seeding Saboround agar and gram staining. The result showed r 0'573, which is higher salivary glucose levels, followed by decreasing salivary pH and microscopic examination of candida found in the whole sample of the study. This finding demonstrates that an increased salivary glucose levels and increase salivary pH affect the occurrence of oral candidiasis in diabetic patients.

    Tuberculosis is a major worldwide problem, and protection from it is achieved mainly by live attenuated bacille Calmette-Guérin vaccine, which is capable of causing disease in immunocompromised host. Oral thrush is abnormal in healthy children, which suggests an underlying immunodeficiency. Mendelian susceptibility to mycobacterial disease is a rare primary immunodeficiency characterized by a selective predisposition to weakly virulent Mycobacteria and Salmonella and also predisposition to chronic mucocutaneous candidiasis. Interleukin 12 receptor β1 (IL-12Rβ1) deficiency is the most common disease of Mendelian susceptibility to mycobacterial disease, and to date only 50 IL-12Rβ1 deficient patients with clinical signs of chronic mucocutaneous candidiasis have been reported. We report a 2.5-year-old daughter of consanguineous parents with both regional bacille Calmette-Guérin lymphadenitis and recurrent oral candidiasis carrying biallelic R175W mutation in the IL12RB1 gene, resulting in complete loss of expression of IL-12Rβ1. To our knowledge, this is the first report of bacille Calmette-Guérin lymphadenitis with concurrent oral candidiasis displaying such a mutation. New mutations and wide clinical diversities are the indisputable fact of populations with a high rate of consanguineous marriages. Copyright © 2017 by the American Academy of Pediatrics.

    We previously report that peptide-pulsed dendritic cell (DC) vaccination, which targeting two peptides (Fba and Met6) expressed on the cell surface of Candida albicans, can induce high degree of protection against disseminated candidiasis in immunocompetent mice. Passive transfer of immune sera from the peptide immunized mice or peptide-related monoclonal antibodies demonstrated that protection was medicated by peptide-specific antibodies. In this study the efficacy of active and passive immunization against disseminated candidiasis was tested in mice with cyclophosphamide-induced neutropenia. Peptide-DC vaccines were given to mice prior to induction of neutropenia. We show active immunization with either Fba or Met6 peptide-DC vaccine significantly improved the survival and reduced the fungal burden of disseminated candidiasis in those immunocompromised mice. Importantly, we show that administration of two protective monoclonal antibodies also protect neutropenic mice against the disease, implying possibility of developing a successful passive immunotherapy strategy to treat the disease and protect against disseminated candidiasis. The results of this study are crucial as they address the fundamental questions as to whether the synthetic peptide vaccine induced immunity protects the host during a neutropenic episode. We anticipate that this peptide-vaccine study will serve as the foundation of future investigations into new peptide vaccines comprised of cell surface peptides from other medically important Candida species, as well as other fungi.

    Non- C. albicans Candida species are increasingly being recognized as the cause of vulvo-vaginal candidiasis. These species are often less susceptible to antifungal agents. Patients with diabetes mellitus are at risk for vulvo-vaginal candidasis. We assessed the species-specific prevalence rate and risk of candidiasis in patients with diabetes mellitus and healthy controls. Genital tract examination, direct microscopy and fungal cultures of discharge collected by high vaginal swab were undertaken among 78 consecutive patients with diabetes mellitus (mean (+/-sd) age 32+/-12 years and body mass index (BMI) 22.3+/-5.5kg/m(2)) and 88 age- and BMI-matched healthy females. Glycaemic control in the diabetic cohort was assessed by measuring total glycosylated haemoglobin. Candida species were isolated in 36 of 78 (46%) subjects with diabetes mellitus and in 21 of 88 (23%) healthy subjects (Chi-squared 9.11, P=0.0025). The predominant Candida species isolated in diabetics with vulvo-vaginal candidiasis were Candida glabrata (39%), C. albicans (26%) and C. tropicalis (17%). In contrast, in the control group, C. albicans, C. glabrata and C. hemulonii comprised 30% each, with none having C. tropicalis infection (for C. tropicalis: diabetic vs. control; 17% vs. nil, P=0. 05). Among the diabetic group, subjects with vulvo-vaginal candidiasis had significantly higher mean HbA1 when compared to those who had no such infection (12.8+/-2.6% vs. 9.7+/-1.7% respectively, P=0.001). The overall accuracy of direct microscopy and clinical examination for predicting vulvo-vaginal candidiasis was only 77% and 51%, respectively, in the diabetic group, and 83% and 65% in the control group. Patients with diabetes mellitus had a high prevalence rate (46%) of vulvo-vaginal candidiasis with relative risk of 2.45. The non- C. albicans species such as C. glabrata and C. tropicalis were the predominant species isolated among them. There seems to be a significant link between hyperglycaemia and

    Testing for Candida albicans germ-tube antibody IFA IgG assay (CAGTA) is used to detect invasive candidiasis infection. However, most suitable assays lack automation and rapid single-sample testing. The CAGTA assay was adapted in an automatic monotest system (invasive candidiasis [CAGTA] VirClia ® IgG monotest (VirClia ® ), a chemiluminescence assay with ready-to-use reagents that provides a rapid objective result. CAGTA assay was compared with the monotest automatic VirClia ® assay in order to establish the diagnostic reliability, accuracy, and usefulness of this method. A prospective study with 361 samples from 179 non-neutropenic critically ill adults patients was conducted, including 21 patients with candidemia, 18 with intra-abdominal candidiasis, 84 with Candida spp. colonization, and 56 with culture-negative samples, as well as samples from ten healthy subjects. Overall agreement between the two assays (CAGTA and VirCLIA) was 85.3%. These assays were compared with the gold-standard method to determine the sensitivity, specificity as well as positive and negative predictive values. In patients with candidemia, values for CAGTA and VirCLIA assays were 76.2 versus 85.7%, 80.3 versus 75.8%, 55.2 versus 52.9%, and 91.4 versus 94.3%, respectively. The corresponding values in patients with intra-abdominal candidiasis were 61.1 versus 66.7%, 80.3 versus 75.8%, 45.8 versus 42.9%, and 88.3 versus 89.3%, respectively. No differences were found according to the species of Candida isolated in culture, except for Candida albicans and C. parapsilosis, for which VirClia ® was better than CAGTA. According to these results, the automated VirClia ® assay was a reliable, rapid, and very easy to perform technique as tool for the diagnosis invasive candidiasis.

    Full Text Available Esophageal candidiasis is the most common opportunistic infection in patients with altered immunity such as Human Immunodeficiency Virus (HIV infection, cancer patients on chemotherapy and radiotherapy. Neutropenia, irradiation and chemotherapy will facilitate deeper mucosal invasion leading to esophageal candidiasis. Empirical treatment of esophageal candidiasis without antifungal susceptibility testing will lead to the emergence of drug resistant species increasing the morbidity and mortality associated with cancer. The present study aimed to study the frequency of esophageal candida in individuals with cancer, species level identification and antifungal susceptibility pattern. Scrapings of whitish appearing lesions were obtained from a total of thirty five cases of endoscopically identified esophageal candidiasis were obtained from cancer patients. Identification of the Candida isolates were done by cultivation in Sabouraud dextrose agar (SDA, Gram staining, germ tube test, colony morphology in Chrom agar and corn meal agar, sugar assimilation and fermentation tests. Antifungal susceptibility was done by Microbroth dilution method for Fluconazole, Itraconazole and Amphotericin B. We found that Candida albicans was the predominant species isolated followed by Candida tropicalis and Candida glabrata. Sensitivity rates were 94%, 96% and 100% for Fluconazole, Itraconazole and Amphotericin B. Species level identification of Candida isolated from esophageal candidiasis and their antifungal sensitivity testing should be performed for early identification of resistant strains and for promptly treating the cases there by preventing the dissemination of infection in case of immune-compromised individuals. Further the susceptibility pattern will facilitate therapeutic guidance especially in individuals prone to relapse. [J Med Allied Sci 2016; 6(1: 29-34

    The da Vinci(®) Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is a computer-assisted (robotic) surgical system designed to enable and enhance minimally invasive surgery. The Food and Drug Administration (FDA) has cleared computer-assisted surgical systems for use by trained physicians in an operating room environment for laparoscopic surgical procedures in general, cardiac, colorectal, gynecologic, head and neck, thoracic and urologic surgical procedures. There are substantial numbers of peer-reviewed papers regarding the da Vinci(®) Surgical System, and a thoughtful assessment of evidence framed by clinical opinion is warranted. The SAGES da Vinci(®) TAVAC sub-committee performed a literature review of the da Vinci(®) Surgical System regarding gastrointestinal surgery. Conclusions by the sub-committee were vetted by the SAGES TAVAC Committee and SAGES Executive Board. Following revisions, the document was evaluated by the TAVAC Committee and Executive Board again for final approval. Several conclusions were drawn based on expert opinion organized by safety, efficacy, and cost for robotic foregut, bariatric, hepatobiliary/pancreatic, colorectal surgery, and single-incision cholecystectomy. Gastrointestinal surgery with the da Vinci(®) Surgical System is safe and comparable, but not superior to standard laparoscopic approaches. Although clinically acceptable, its use may be costly for select gastrointestinal procedures. Current data are limited to the da Vinci(®) Surgical System; further analyses are needed.

    The current standard of treatment of invasive candidiasis with echinocandins requires once-daily therapy. To improve quality of life, reduce costs, and improve outcome, we studied the pharmacokinetics (PK), efficacy, and safety of alternate dosing regimens of micafungin (MFG) for the treatment of experimental subacute disseminated candidiasis. MFG was administered for 12 days starting 24 hours after intravenous inoculation of 1 × 10(3) Candida albicans blastoconidia. Study groups consisted of MFG at 1 mg/kg every 24 hours (MFG1), 2 mg/kg every 48 hours (MFG2), and 3 mg/kg every 72 hours (MFG3), and untreated controls. PK of MFG were determined on day 7 by high-performance liquid chromatography and modeled using nonparametric adaptive grid program. A 2-compartment PK model with volume of the central compartment (Vc), clearance (SCL), and the intercompartmental rate constants Kcp and Kpc was used. The fungal burden in 7 tissues was determined 312 hours after the initiation of therapy. PK of MFG were linear and the parameter means ± SD were Vc = 0.41 ± 0.18 L, Kcp = 2.80 ± 1.55/hour, Kpc = 1.71 ± 0.93/hour, and SCL = 0.16 ± 0.003 L/hour (r(2) = 0.99). The area under the plasma drug concentration - time curve for MFG1, MFG2, and MFG3 was 198.7 ± 19.8, 166.3 ± 36.7, and 192.8 ± 46.2 mg × hour/L, respectively (P = .24). All treatment groups showed significant and comparable resolution of (1→3)-β-D-glucan levels and clearance of C. albicans from liver, spleen, kidney, brain, lung, vitreous humor, and vena cava in comparison to untreated controls (P ≤ .05). There were no differences in hepatic or renal function among study groups. Less fractionated MFG regimens of every 48 and 72 hours are safe and as effective in experimental disseminated candidiasis as once-daily therapy in neutropenic hosts. © The Author 2015.

    Treatment of vulvovaginal candidiasis (VVC), caused most frequently by Candida albicans, represents a significant unmet clinical need. C. albicans, as both a commensal and a pathogenic organism, has a complex and poorly understood interaction with the vaginal environment. Understanding the complex nature of this relationship is necessary for the development of desperately needed therapies to treat symptomatic infection. Using transcriptome sequencing (RNA-seq), we characterized the early murine vaginal and fungal transcriptomes of the organism during VVC. Network analysis of host genes that were differentially expressed between infected and naive mice predicted the activation or repression of several signaling pathways that have not been previously associated with VVC, including NLRP3 inflammasome activation. Intravaginal challenge of Nlrp3(-/-) mice with C. albicans demonstrated severely reduced levels of polymorphonuclear leukocytes (PMNs), alarmins, and inflammatory cytokines, including interleukin-1β (IL-1β) (the hallmarks of VVC immunopathogenesis) in vaginal lavage fluid. Intravaginal administration of wild-type (WT) mice with glyburide, a potent inhibitor of the NLRP3 inflammasome, reduced PMN infiltration and IL-1β to levels comparable to those observed in Nlrp3(-/-) mice. Furthermore, RNA-seq analysis of C. albicans genes indicated robust expression of hypha-associated secreted aspartyl proteinases 4, 5, and 6 (SAP4-6), which are known inflammasome activators. Despite colonization similar to that of the WT strain, ΔSAP4-6 triple and ΔSAP5 single mutants induced significantly less PMN influx and IL-1β during intravaginal challenge. Our findings demonstrate a novel role for the inflammasome in the immunopathogenesis of VVC and implicate the hypha-associated SAPs as major C. albicans virulence determinants during vulvovaginal candidiasis. Vaginitis, most commonly caused by the fungus Candida albicans, results in significant quality-of-life issues for

    2018-04-01

    Proper formal documentation of computer acquired NDE experimental data generated during research is critical to the longevity and usefulness of the data. Without documentation describing how and why the data was acquired, NDE research teams lose capability such as their ability to generate new information from previously collected data or provide adequate information so that their work can be replicated by others seeking to validate their research. Despite the critical nature of this issue, NDE data is still being generated in research labs without appropriate documentation. By generating documentation in series with data, equal priority is given to both activities during the research process. One way to achieve this is to use a reactive documentation system (RDS). RDS prompts an operator to document the data as it is generated rather than relying on the operator to decide when and what to document. This paper discusses how such a system can be implemented in a dynamic environment made up of in-house and third party NDE data acquisition systems without creating additional burden on the operator. The reactive documentation approach presented here is agnostic enough that the principles can be applied to any operator controlled, computer based, data acquisition system.

    Candidiasis is a common fungal infection that is prevalent in immunocompromised individuals. In this study, an oral vaccine against Candida albicans was developed by using the molecular display approach. Enolase 1 protein (Eno1p) of C. albicans was expressed on the Lactobacillus casei cell surface by using poly-gamma-glutamic acid synthetase complex A from Bacillus subtilis as an anchoring protein. The Eno1p-displaying L. casei cells were used to immunize mice, which were later challenged with a lethal dose of C. albicans. The data indicated that the vaccine elicited a strong IgG response and increased the survival rate of the vaccinated mice. Furthermore, L. casei acted as a potent adjuvant and induced high antibody titers that were comparable to those induced by strong adjuvants such as the cholera toxin. Overall, the molecular display method can be used to rapidly develop vaccines that can be conveniently administered and require minimal processing.

    Enolase 1 (Eno1p) of Candida albicans is an immunodominant antigen. However, conventional technologies for preparing an injectable vaccine require purification of the antigenic protein and preparation of an adjuvant. To develop a novel type of oral vaccine against candidiasis, we generated Saccharomyces cerevisiae cells that display the Eno1p antigen on their surfaces. Oral delivery of the engineered S. cerevisiae cells prolonged survival rate of mice that were subsequently challenged with C. albicans. Given that a vaccine produced using molecular display technology avoids the need for protein purification, this oral vaccine offers a promising alternative to the use of conventional and injectable vaccines for preventing a range of infectious diseases. © 2013 Federation of European Microbiological Societies.

    A 44-year-old woman with a history of intermittent fever for several years was admitted because of burn on her leg. On admission, she had hepatosplenomegaly and fever. Antibiotic therapy was started for bacterial infection of the burn. She lost her appetite and IVH was started. During the treatment, high fever appeared and chest X-ray films showed multiple nodular infiltrates throughout both lung fields. Candida albicans was isolated from IVH catheter culture and pulmonary candidiasis was suspected. Her fever and lung involvements were successfully treated with fluconazole. During the course, serum anti-EB-VCA-IgG antibody persisted at a high titer and anti-EBNA antibody remained negative. EB virus DNA was detected in the peripheral blood and bone marrow. Thus, she was diagnosed as chronic active EB virus infection.

    The present study was designed to develop a nanoemulsion formulation of Amphotericin B (AmB) for the treatment of skin candidiasis and aspergillosis. Several ingredients were selected on the basis of AmB solubility and compatibility with skin. The formulation that exhibited the best properties was selected from the pseudo-ternary phase diagram. After physicochemical characterization its stability was assessed. Drug release and skin permeation studies were also accomplished. The antifungal efficacy and skin tolerability of developed AmB nanoemulsion was demonstrated. Finally, our results showed that the developed AmB formulation could provide an effective local antifungal effect without theoretical systemic absorption, based on its skin retention capacity, which might avoid related side effect. These results suggested that the nanoemulsion may be an optimal therapeutic alternative for the treatment of skin fungal infections with AmB. Copyright © 2017 Elsevier Inc. All rights reserved.

    Monocytes are innate immune cells that play a pivotal role in antifungal immunity, but little is known regarding the cellular metabolic events that regulate their function during infection. Using complementary transcriptomic and immunological studies in human primary monocytes, we show that activation of monocytes by Candida albicans yeast and hyphae was accompanied by metabolic rewiring induced through C-type lectin-signaling pathways. We describe that the innate immune responses against Candida yeast are energy-demanding processes that lead to the mobilization of intracellular metabolite pools and require induction of glucose metabolism, oxidative phosphorylation and glutaminolysis, while responses to hyphae primarily rely on glycolysis. Experimental models of systemic candidiasis models validated a central role for glucose metabolism in anti-Candida immunity, as the impairment of glycolysis led to increased susceptibility in mice. Collectively, these data highlight the importance of understanding the complex network of metabolic responses triggered during infections, and unveil new potential targets for therapeutic approaches against fungal diseases.

    E1210 is a first-in-class, broad-spectrum antifungal with a novel mechanism of action-inhibition of fungal glycosylphosphatidylinositol biosynthesis. In this study, the efficacies of E1210 and reference antifungals were evaluated in murine models of oropharyngeal and disseminated candidiasis, pulmonary aspergillosis, and disseminated fusariosis. Oral E1210 demonstrated dose-dependent efficacy in infections caused by Candida species, Aspergillus spp., and Fusarium solani. In the treatment of oropharyngeal candidiasis, E1210 and fluconazole each caused a significantly greater reduction in the number of oral CFU than the control treatment (P candidiasis model, mice treated with E1210, fluconazole, caspofungin, or liposomal amphotericin B showed significantly higher survival rates than the control mice (P candidiasis caused by azole-resistant Candida albicans or Candida tropicalis. A 24-h delay in treatment onset minimally affected the efficacy outcome of E1210 in the treatment of disseminated candidiasis. In the Aspergillus flavus pulmonary aspergillosis model, mice treated with E1210, voriconazole, or caspofungin showed significantly higher survival rates than the control mice (P candidiasis, pulmonary aspergillosis, and disseminated fusariosis. These data suggest that further studies to determine E1210's potential for the treatment of disseminated fungal infections are indicated.

    Full text: To obtain an effective and coherent documentation system suitable for CNEA's Quality Management Program, we decided to organize the CNEA's quality documentation with : a- Level 1. Quality manual. b- Level 2. Procedures. c-Level 3. Qualities plans. d- Level 4: Instructions. e- Level 5. Records and other documents. The objective of this work is to present a standardization of the documentation of the CNEA's quality system of facilities, laboratories, services, and R and D activities. Considering the diversity of criteria and formats for elaboration the documentation by different departments, and since ultimately each of them generally includes the same quality management policy, we proposed the elaboration of a system in order to improve the documentation, avoiding unnecessary time wasting and costs. This will aloud each sector to focus on their specific documentation. The quality manuals of the atomic centers fulfill the rule 3.6.1 of the Nuclear Regulatory Authority, and the Safety Series 50-C/SG-Q of the International Atomic Energy Agency. They are designed by groups of competent and highly trained people of different departments. The normative procedures are elaborated with the same methodology as the quality manuals. The quality plans which describe the organizational structure of working group and the appropriate documentation, will asses the quality manuals of facilities, laboratories, services, and research and development activities of atomic centers. The responsibilities for approval of the normative documentation are assigned to the management in charge of the administration of economic and human resources in order to fulfill the institutional objectives. Another improvement aimed to eliminate unnecessary invaluable processes is the inclusion of all quality system's normative documentation in the CNEA intranet. (author) [es

    The purpose of this study was to determine the prevalence of oral microflora and association of oral candidiasis and multiple risk factors in HIV(+) patients. The present study included 100 HIV-infected patients participated in Imam Khomeini Hospital, Tehran, Iran for Oropharyngeal candidiasis (OPC) and HIV. We assessed the presence or absence of OPC, and samples were obtained from the oral cavity and direct microscopic examination, gram staining and culture on standard microbiological media were performed in all patients. CD4(+) cell count/CD4(+) percentage were also calculated. The demographic characteristics showed that the patients had a mean age of 32.3 years old, 78% male and 22% female. Patients belonging to 'O(+)' blood group (27%) were more prone to develop OPC. A total of 460 bacterial colonies were obtained and Streptococcus mutans (15.4%) was the most frequently isolated species in the HIV(+) patients, followed by Staphylococcus epidermidis (12.8%) and Corynebacterium (8.7%). In addition, 254 yeasts (from four different genera) were isolated from the patient under study. Candida species (94.4%) were the most frequently obtained genera, followed by Saccharomyces (2.4%), Kluyveromyces and Cryptococcus (1.6% for both) species. Candida albicans (37.2%) was the most common species isolated from HIV(+) patients with OPC and its frequency was significantly higher than that of other Candida species (Poral cavity of HIV(+) patients and there was no significant difference of the variables CD4(+) cell count and yeast counts. The findings of this study would be helpful in any further study, which, if done prospectively on a large cohort, can be confirmatory. Copyright © 2013. Published by Elsevier SAS.

    Candida albicans, a commensal fungus of the oral microbiome, causes oral candidiasis in humans with localized or systemic immune deficiencies. Secreted aspartic proteinases (Saps) are a family of 10 related proteases and are virulence factors due to their proteolytic activity, as well as their roles in adherence and colonization of host tissues. We found that mice infected sublingually with C. albicans cells overexpressing Sap6 (SAP6 OE and a Δsap8 strain) had thicker fungal plaques and more severe oral infection, while infection with the Δsap6 strain was attenuated. These hypervirulent strains had highly aggregative colony structure in vitro and higher secreted proteinase activity; however, the levels of proteinase activity of C. albicans Saps did not uniformly match their abilities to damage cultured oral epithelial cells (SCC-15 cells). Hyphal induction in cells overexpressing Sap6 (SAP6 OE and Δsap8 cells) resulted in formation of large cell-cell aggregates. These aggregates could be produced in germinated wild-type cells by addition of native or heat-inactivated Sap6. Sap6 bound only to germinated cells and increased C. albicans adhesion to oral epithelial cells. The adhesion properties of Sap6 were lost upon deletion of its integrin-binding motif (RGD) and could be inhibited by addition of RGD peptide or anti-integrin antibodies. Thus, Sap6 (but not Sap5) has an alternative novel function in cell-cell aggregation, independent of its proteinase activity, to promote infection and virulence in oral candidiasis.

    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.

    As the most common fungal pathogen of humans, severe drug resistance has emerged in the clinically isolated Candida albicans, which lead to the urgency to develop novel antifungal agents. Here, four our previously characterized cathelicidins (cathelicidin-BF, Pc-CATH1, Cc-CATH2, Cc-CATH3) were selected and their antifungal activities against C. albicans were evaluated in vitro and in vivo using amphotericin B and LL-37 as control. Results showed that all four cathelicidins could eradicate standard and clinically isolated C. albicans strains with most MIC values ranging from 1 to 16 μg/ml, in less than 0.5 h revealed by time-kill kinetic assay. Four peptides only exhibited slight hemolytic activity with most HC50 > 200 μg/ml, and retained potent anti-C. albicans activity at salt concentrations below and beyond physiological level. In animal experiment, 50 mg/kg administration of the four cathelicidins could significantly reduce the fungal counts in a murine oral candidiasis model induced by clinically isolated C. albicans. The antibiofilm activity of cathelicidin-BF, the most potent among the five peptides was evaluated, and result showed that cathelicidin-BF strongly inhibited C. albicans biofilm formation at 20 μg/ml. Furthermore, cathelicidin-BF also exhibited potent anti-C. albicans activity in established biofilms as measured by metabolic and fluorescent viability assays. Structure-function analyses suggest that they mainly adopt an α-helical conformations, which enable them to act as a membrane-active molecule. Altogether, the four cathelicidins display great potential for antifungal agent development against candidiasis.

    Neonatal invasive candidiasis (IC) presenting in the first week of life is less common and less well described than later-onset IC. Risk factors, clinical features, and disease outcomes have not been studied in early-onset disease (EOD, ≤7 days) or compared to late-onset disease (LOD, >7 days). All extremely low birth weight (ELBW, candidiasis enrolled from 2001 to 2003 were included in this study. Factors associated with occurrence and outcome of EOD in ELBW infants were determined. Forty-five ELBW infants and their 84 matched controls were included. Fourteen (31%) ELBW infants had EOD. Birth weight <750 g, gestation <25 weeks, chorioamnionitis, and vaginal delivery were all strongly associated with EOD. Infection with Candida albicans, disseminated disease, pneumonia, and cardiovascular disease were significantly more common in EOD than in LOD. The EOD case fatality rate (71%) was higher than in LOD (32%) or controls (15%) (P = .0001). The rate of neurodevelopmental impairment and mortality combined was similar in EOD (86%) and LOD (72%), but higher than in controls (32%; P = .007). ELBW infants with EOD have a very poor prognosis compared to those with LOD. The role of perinatal transmission in EOD is supported by its association with chorioamnionitis, vaginal delivery, and pneumonia. Dissemination and cardiovascular involvement are common, and affected infants often die. Empiric treatment should be considered for ELBW infants delivered vaginally who have pneumonia and whose mothers have chorioamnionitis or an intrauterine foreign body. © The Author 2017.

    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 α4β7, αM290β7, and α4β1 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.

    Women often develop vaginal infections that are caused primarily by organisms of the genus Candida. The current treatments of vaginal candidiasis usually involve azole-based antifungals, though fungal resistance to these compounds has become prevalent. Therefore, much attention has been given to molecules with antifungal properties from natural sources, such as curcumin (CUR). However, CUR has poor solubility in aqueous solvents and poor oral bioavailability. This study attempted to overcome this problem by developing, characterizing, and evaluating the in vitro antifungal action of a CUR-loaded liquid crystal precursor mucoadhesive system (LCPM) for vaginal administration. A low-viscosity LCPM (F) consisting of 40% wt/wt polyoxpropylene-(5)-polyoxyethylene-(20)-cetyl alcohol, 50% wt/wt oleic acid, and 10% wt/wt chitosan dispersion at 0.5% with the addition of 16% poloxamer 407 was developed to take advantage of the lyotropic phase behavior of this formulation. Notably, F could transform into liquid crystal systems when diluted with artificial vaginal mucus at ratios of 1:3 and 1:1 (wt/wt), resulting in the formation of F30 and F100, respectively. Polarized light microscopy and rheological studies revealed that F behaved like an isotropic formulation, whereas F30 and F100 behaved like an anisotropic liquid crystalline system (LCS). Moreover, F30 and F100 presented higher mucoadhesion to porcine vaginal mucosa than F. The analysis of the in vitro activity against Candida albicans revealed that CUR-loaded F was more potent against standard and clinical strains compared with a CUR solution. Therefore, the vaginal administration of CUR-loaded LCPMs represents a promising platform for the treatment of vaginal candidiasis.

    Full Text Available Herbal-loaded drug delivery nanotechnological systems have been extensively studied recently. The antimicrobial activity of medicinal plants has shown better pharmacological action when such plants are loaded into a drug delivery system than when they are not loaded. Syngonanthus nitens Bong. (Rhul. belongs to the Eriocaulaceae family and presents antiulcerogenic, antioxidant, antibacterial, and antifungal activity. The aim of this study was to evaluate the antifungal activity of Syngonanthus nitens (S. nitens extract that was not loaded (E or loaded (SE into a liquid crystal precursor system (S for the treatment of vulvovaginal candidiasis (VVC with Candida albicans. The minimal inhibitory concentration (MIC was determined by the microdilution technique. Additionally, we performed hyphae inhibition and biofilm tests. Finally, experimental candidiasis was evaluated in in vivo models with Wistar female rats. The results showed effective antifungal activity after incorporation into S for all strains tested, with MICs ranging from 31.2 to 62.5 μg/mL. Microscopic observation of SE revealed an absence of filamentous cells 24 h of exposure to a concentration of 31.2 μg/mL. E demonstrated no effective action against biofilms, though SE showed inhibition against biofilms of all strains. In the in vivo experiment, SE was effective in the treatment of infection after only two days of treatment and was more effective than E and amphotericin B. The S. nitens is active against Candida albicans (C. albicans and the antifungal potential is being enhanced after incorporation into liquid crystal precursor systems (LCPS. These findings represent a promising application of SE in the treatment of VVC.

    To assess the incidence of oral candidiasis and its influencing factors in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). An oral examination was conducted in the 1 566 HIV/AIDS patients in the Third Hospital of Kunming from March 2008 to September 2012 (M/F: 1 062/504, age range: 0.2 to 84.0 years old). The HIV viral load (HIV- RNA) and peripheral blood CD4 count were respectively analyzed by Bayer Q340 fluorescence signal surveying instrument (bDNA method) and flow cytometry analysis. The information on usage of highly active anti-retroviral (HAART) drugs and transmission of HIV were obtained through questionnaires. The incidence of oral candidiasis in patients with different HIV-RNA levels and CD4 count and the use of HAART was analyzed and compared. The total incidence of oral candidosis was 31.0% (486/1 566) and there was no difference in sex. The oral lesions were presented by three types, psudomembranous candidosis (PC), erythematous candidosis (EC) and angular cheilitis (AC), and the morbidity was 13.9% (217/1 566), 17.0% (267/1 566) and 4.9% (77/1 566), respectively. The average level of CD4 count in psudomembranous candidosis, erythematous candidosis and angular cheilitis [81.0 (146.0), 74.0 (152.0) and 69.0 (121.5) cell/µl] showed no significant difference (P > 0.05). The incidence of oral candidiasis in non-HAART and HAART subjects were 36.3% (402/1 107) and 18.3% (84/459), respectively (P = 0.000). The CD4 count and absolute counts of HIV viral load in oral candidiasis patients and non-oral candidiasis patients had significant difference (Z = -10.261, P = 0.000 and Z = -4.762, P = 0.000). The morbidity of oral candidiasis in HIV/AIDS patients in Yunnan Province was high, including PC, EC and AC and hyperplastic candidosis was not detected. The incidence was related to the degree of immune suppression and HIV viral load.

    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.

    2011-01-01

    My project at KSC during my spring 2011 internship was to develop a Ruby on Rails application to manage Content Documents..A Content Document is a collection of documents and information that describes what software is installed on a Launch Control System Computer. It's important for us to make sure the tools we use everyday are secure, up-to-date, and properly licensed. Previously, keeping track of the information was done by Excel and Word files between different personnel. The goal of the new application is to be able to manage and access the Content Documents through a single database backed web application. Our LCS team will benefit greatly with this app. Admin's will be able to login securely to keep track and update the software installed on each computer in a timely manner. We also included exportability such as attaching additional documents that can be downloaded from the web application. The finished application will ease the process of managing Content Documents while streamlining the procedure. Ruby on Rails is a very powerful programming language and I am grateful to have the opportunity to build this application.

    SPECTROM-32 is a finite element program for analyzing two-dimensional and axisymmetric inelastic thermomechanical problems related to the geological disposal of nuclear waste. The code is part of the SPECTROM series of special-purpose computer programs that are being developed by RE/SPEC Inc. to address many unique rock mechanics problems encountered in analyzing radioactive wastes stored in geologic formations. This document presents the theoretical basis for the mathematical models, the finite element formulation and solution procedure of the program, a description of the input data for the program, verification problems, and details about program support and continuing documentation. The computer code documentation is intended to satisfy the requirements and guidelines outlined in the document entitled Final Technical Position on Documentation of Computer Codes for High-Level Waste Management. The principal component models used in the program involve thermoelastic, thermoviscoelastic, thermoelastic-plastic, and thermoviscoplastic types of material behavior. Special material considerations provide for the incorporation of limited-tension material behavior and consideration of jointed material behavior. Numerous program options provide the capabilities for various boundary conditions, sliding interfaces, excavation, backfill, arbitrary initial stresses, multiple material domains, load incrementation, plotting database storage and access of results, and other features unique to the geologic disposal of radioactive wastes. Numerous verification problems that exercise many of the program options and illustrate the required data input and printed results are included in the documentation

    Oral candidiasis is the most common fungal infection and can be attributed in part to dysbiosis, an imbalance in the resident oral microflora. Therefore, probiotics, which counter pathogenic microorganisms through competitive, antagonistic, and immunological effects, have been used by some clinicians. To date, the effect of probiotics in preventing oral candidiasis in the elderly is controversial. A systematic review that summarizes and critically appraises the available clinical trials is therefore necessary. Electronic searches were performed using the Pubmed, Embase, and Cochrane databases. Only randomized controlled trials were included. The Mantel-Haenszel test was used to appraise the odds ratio for single studies and an overall combined odds ratio for all studies combined. Three studies matched the inclusion criteria and were homogeneous. The data from one study that estimated candida growth from plaque and saliva were subdivided, thus a total of four studies with 595 people were included. The overall combined odds ratio was 0.54 (95% CI: 0.38-0.77). Three studies provided that active treatment reduced the risk of oral candidiasis more than placebo: Hatakka et al. (OR 0.51, 95% CI 0.26 to 0.97; 192 participants, plaque); Kraft-Bodi et al. (OR 0.46, 95% CI 0.24 to 0.86; 174 participants, palatal); Kraft-Bodi et al. (OR 0.50, 95% CI 0.26 to 0.98; 174 participants, plaque), while one study provided reverse result: Ishikawa et al. (OR 1.24, 95% CI 0.48 to 3.58; 55 participants, saliva). Probiotics have a preventative effect on oral candidiasis in the elderly. Copyright © 2017. Published by Elsevier Ltd.

    Clinical management of patients undergoing treatment of oropharyngeal candidiasis with azole antifungals can be impaired by azole resistance. High-level azole resistance is often caused by the overexpression of Candida albicans efflux pump Cdr1p. Inhibition of this pump therefore represents a target for combination therapies that reverse azole resistance. We assessed the therapeutic potential of the D-octapeptide derivative RC21v3, a Cdr1p inhibitor, in the treatment of murine oral candidiasis caused by either the azole-resistant C. albicans clinical isolate MML611 or its azole-susceptible parental strain MML610. RC21v3, fluconazole (FLC), or a combination of both drugs were administered orally to immunosuppressed ICR mice at 3, 24, and 27 h after oral inoculation with C. albicans. FLC protected the mice inoculated with MML610 from oral candidiasis, but was only partially effective in MML611-infected mice. The co-application of RC21v3 (0.02 μmol per dose) potentiated the therapeutic performance of FLC for mice infected with either strain. It caused a statistically significant decrease in C. albicans cfu isolated from the oral cavity of the infected mice and reduced oral lesions. RC21v3 also enhanced the therapeutic activity of itraconazole against MML611 infection. These results indicate that RC21v3 in combination with azoles has potential as a therapy against azole-resistant oral candidiasis. © 2011 Federation of European Microbiological Societies.

    Compare the safety and efficacy of topical gentian violet with that of nystatin oral suspension (NYS) for the treatment of oropharyngeal candidiasis in HIV-1-infected adults in resource-limited settings. Multicenter, open-label, evaluator-blinded, randomized clinical trial at eight international sites, within the AIDS Clinical Trials Group. Adult HIV-infected participants with oropharyngeal candidiasis, stratified by CD4 cell counts and antiretroviral therapy status at study entry, were randomized to receive either gentian violet (0.00165%, BID) or NYS (500 000 units, QID) for 14 days. Cure or improvement after 14 days of treatment. Signs and symptoms of oropharyngeal candidiasis were evaluated in an evaluator-blinded manner. The study was closed early per Data Safety Monitoring Board after enrolling 221 participants (target = 494). Among the 182 participants eligible for efficacy analysis, 63 (68.5%) in the gentian violet arm had cure or improvement of oropharyngeal candidiasis versus 61 (67.8%) in the NYS arm, resulting in a nonsizable difference of 0.007 (95% confidence interval: -0.129, 0.143). There was no sizable difference in cure rates between the two arms (-0.0007; 95% confidence interval: -0.146, 0.131). No gentian violet-related adverse events were noted. No sizable differences were identified in tolerance, adherence, quality of life, or acceptability of study drugs. In gentian violet arm, 61 and 39% of participants reported 'no' and 'mild-to-moderate' staining, respectively. Cost for medication procurement was significantly lower for gentian violet versus NYS (median $2.51 and 19.42, respectively, P = 0.01). Efficacy of gentian violet was not statistically different than NYS, was well tolerated, and its procurement cost was substantially less than NYS.

    Lasioglossins are a group of peptides with identified antimicrobial activity. The inhibitory effects of two synthetic lasioglossin derivatives, LLIII and D-isomeric variant LLIII-D, on morphological changes in Candida albicans in vitro and the effect of local administration of LLIII during experimental murine candidiasis were investigated. C. albicans blastoconidia were grown in the presence of lasioglossin LLIII or LLIII-D at concentrations of 11.5 μM and 21 μM, respectively, for 1, 2 and 3 days and their viability determined by flow cytometry using eosin Y staining. Morphological changes were examined by light and fluorescent microscopy. The Candida-inhibitory effect of daily intravaginal administration of 0.7 or 1.4 μg of LLIII was assessed in mice with experimentally-induced vaginal candidiasis. LLIII and LLIII-D lasioglossins exhibited candidacidal activity in vitro (>76% after 24 hr and >84% after 48 hr of incubation). After 72 hr incubation of Candida with low concentration of lasioglossins, an increase in viability was detected, probably due to a Candida antimicrobial peptides evasion strategy. Furthermore, lasioglossins inhibited temperature-induced morphotype changes toward hyphae and pseudohyphae with sporadic occurrence of atypical cells with two or enlarged nuclei, suggesting interference with mitosis or cytokinesis. Local application of LLIII reduced the duration of experimental candidiasis with no evidence of adverse effects. Lasioglossin LLIII is a promising candidate for development as an antimicrobial drug for treating the vaginal candidiasis. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

    In clinical practice, recurrence of thrush is common in children living with HIV/AIDS. The aim of this study was to determine the factors associated with time spent free of oral candidiasis using survival analysis for recurrent events. A retrospective cohort study was carried out with 287 children treated between 1985 and 2009 at a reference center in the city of São Paulo, Brazil. The Prentice, Williams and Peterson model for recurrent events was used for the investigation of factors associated with the time free of oral candidiasis. The following factors were associated with the time patients were free of oral candidiasis: moderate immunodepression (HR = 2.5; p = 0.005), severe immunodepression (HR = 3.5; p < 0.001), anemia (HR = 3.3; p < 0.001), malnutrition (HR = 2.6; p = 0.004), hospitalization (HR = 2.2; p < 0.001), monotherapy (HR = 0.5; p = 0.006), dual therapy (HR = 0.3; p < 0.001) and triple therapy/highly active antiretroviral therapy (HR = 0.1; p < 0.001). The method analyzed in the present study proved useful for the investigation of recurrent events in patients living with HIV/AIDS.

    Neutrophils play a crucial role in defense against systemic candidiasis, a disease associated with a high mortality rate in patients receiving immunosuppressive therapy, although the early immune mechanisms that boost the candidacidal activity of neutrophils remain to be defined in depth. Here, we used a murine model of systemic candidiasis to explore the role of inflammatory Ly6C high monocytes in NK cell-mediated neutrophil activation during the innate immune response against C. albicans. We found that efficient anti-Candida immunity required a collaborative response between the spleen and kidney, which relied on type I interferon-dependent IL-15 production by spleen inflammatory Ly6C high monocytes to drive efficient activation and GM-CSF release by spleen NK cells; this in turn was necessary to boost the Candida killing potential of kidney neutrophils. Our findings unveil a role for IL-15 as a critical mediator in defense against systemic candidiasis and hold promise for the design of IL-15-based antifungal immunotherapies.

    Background. The pathogenesis of intra-abdominal candidiasis is poorly understood. Methods. Mice were intraperitoneally infected with Candida albicans (1 × 106 colony-forming units) and sterile stool. nanoString assays were used to quantitate messenger RNA for 145 C. albicans genes within the peritoneal cavity at 48 hours. Results. Within 6 hours after infection, mice developed peritonitis, characterized by high yeast burdens, neutrophil influx, and a pH of 7.9 within peritoneal fluid. Organ invasion by hyphae and early abscess formation were evident 6 and 24 hours after infection, respectively; abscesses resolved by day 14. nanoString assays revealed adhesion and responses to alkaline pH, osmolarity, and stress as biologic processes activated in the peritoneal cavity. Disruption of the highly-expressed gene RIM101, which encodes an alkaline-regulated transcription factor, did not impact cellular morphology but reduced both C. albicans burden during early peritonitis and C. albicans persistence within abscesses. RIM101 influenced expression of 49 genes during intra-abdominal candidiasis, including previously unidentified Rim101 targets. Overexpression of the RIM101-dependent gene SAP5, which encodes a secreted protease, restored the ability of a rim101 mutant to persist within abscesses. Conclusions. A mouse model of intra-abdominal candidiasis is valuable for studying pathogenesis and C. albicans gene expression. RIM101 contributes to persistence within intra-abdominal abscesses, at least in part through activation of SAP5. PMID:24006479

    To measure the change of glucose in vaginal secretions during glucose tolerance testing in women with recurrent vulvovaginal candidiasis and in healthy control subjects. Thirty-eight women with recurrent vulvovaginal candidiasis and 45 healthy, age-matched controls completed a health questionnaire regarding general and gynecologic health and food and alcohol habits. They all underwent an oral glucose tolerance test and a vaginal examination. Vaginal secretion was collected from the proximal part of the vagina. Glucose in plasma and in vaginal secretions were measured at fasting and after 2 hours and analyzed with the hexokinase method. A sample size analysis showed that the number of subjects included in the study was sufficient for a beta value of 0.80, at the significance level of alpha=.05, at a difference in glucose in vaginal secretions of 30% after oral glucose tolerance test. In healthy women, the median level of glucose in vaginal secretions was 5.2 mM before and 3.7 mM after oral glucose tolerance test, and plasma glucose was 5.0 mM before and 5.8 mM after oral glucose tolerance test. No significant difference was seen regarding change of glucose level in vaginal secretions and plasma glucose after testing, compared with before oral glucose tolerance testing. There were no differences between women with recurrent vulvovaginal candidiasis and control subjects regarding change in glucose level in vaginal secretions or in plasma during oral glucose tolerance test.

    Sexually transmitted diseases (STD) are a major health problem affecting mostly young people in both developing and developed countries. STD in women causes both acute morbidity and complications such as infertility, ectopic pregnancy, low-birth weight, and prematurity. The aim of the study is to assess the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic females attending STD outpatient department in a tertiary care hospital in South India. A retrospective analysis of data collected from clinical records of 3000 female patients of age 18 to 49 over a period of 12 months (July 2014 to June 2015) was carried out at the Institute of Venereology, Madras Medical College. Complete epidemiological, clinical, and investigational data were recorded and analyzed for the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic patients. About 48.37% (228/470) of bacterial vaginosis patients were asymptomatic. Nearly 45.38% (116/235) of vaginal candidiasis patients were asymptomatic and 30.35% (26/87) of trichomoniasis patients were asymptomatic. The above infections were common in the age group 25-35. Holistic screening protocol was incorporated for all female patients attending STD clinic even if asymptomatic and should be treated accordingly to prevent the acquisition of other serious sexually transmitted infections.

    In order to evaluate an effective administration method of essential oils for vaginal candidiasis, efficacy of vaginal application of essential oils against murine experimental candidiasis was investigated. The effect on vaginal inflammation and Candida growth form was also studied. Vaginal candidiasis was established by intravaginal infection of C. albicans to estradiol-treated mice. These mice intravaginally received essential oils such as geranium and tea tree singly or in combination with vaginal washing. Vaginal administration of clotrimazole significantly decreased the number of viable C. albicans cells in the vaginal cavity by itself. In contrast, these essential oils did not lower the cell number. When application of geranium oil or geraniol was combined with vaginal washing, the cell number was decreased significantly. The myeloperoxidase activity assay exhibited the possibility that essential oils worked not only to reduce the viable cell number of C. albicans, but also to improve vaginal inflammation. The smear of vaginal washing suspension suggested that more yeast-form cells appeared in vaginal smears of these oil-treated mice than in control mice. In vitro study showed that a very low concentration (25 microg/ml) of geranium oil and geraniol inhibited mycelial growth, but not yeast growth. Based on these findings, it is estimated that vaginal application of geranium oil or its main component, geraniol, suppressed Candida cell growth in the vagina and its local inflammation when combined with vaginal washing.

  9. Gain-of-Function Mutations in STAT1: A Recently Defined Cause for Chronic Mucocutaneous Candidiasis Disease Mimicking Combined Immunodeficiencies

    Full Text Available Chronic Mucocutaneous Candidiasis (CMC is the chronic, recurrent, noninvasive Candida infections of the skin, mucous membranes, and nails. A 26-month-old girl was admitted with the complaints of recurrent oral Candidiasis, diarrhea, and respiratory infections. Candida albicans grew in oral mucosa swab. CMV and EBV DNA titers were elevated. She had hypergammaglobulinemia; IgE level, percentages of lymphocyte subgroups, and in vitro T-cell proliferation responses were normal. She had parenchymal nodules within the lungs and a calcific nodule in the liver. Chronic-recurrent infections with different pathogens leading to significant morbidity suggested combined immunodeficiency, CMC, or Mendelian susceptibility to mycobacterial diseases. Genetic analysis revealed a predefined heterozygous gain-of-function mutation (GOF (c.1154 C>T, p.Thr385Met in the gene coding STAT1 molecule. Hematopoietic stem cell transplantation (HSCT was planned because of severe recurring infections. Patients with STAT1 GOF mutations may exhibit diverse phenotypes including infectious and noninfectious findings. HSCT should be considered as an early treatment option before permanent organ damage leading to morbidity and mortality develops. This case is presented to prompt clinicians to consider STAT1 GOF mutations in the differential diagnosis of patients with chronic Candidiasis and recurrent infections with multiple organisms, since these mutations are responsible for nearly half of CMC cases reported.

    Candida albicans, normally found as a commensal in the gut, is a major human fungal pathogen responsible for both mucosal and systemic infections in a wide variety of immunocompromised individuals, including cancer patients and organ transplant recipients. The gastrointestinal tract represents a major portal of entry for the establishment of disseminated candidiasis in many of these individuals. Here we report the development of a diet-based mouse model for disseminated candidiasis acquired via the gastrointestinal tract. Using this model, as well as an appropriate immunosuppression regimen, we demonstrate that dissemination of C. albicans from the gastrointestinal tract can result in mortality within 30 days postinfection. We also show a significant increase in fungal burden in systemic organs, but not gastrointestinal tract organs, upon immunosuppression. Importantly, we demonstrate that the administration of two widely used antifungals, fluconazole and caspofungin, either pre- or postimmunosuppression, significantly reduces fungal burdens. This model should prove to be of significant value for testing the ability of both established and experimental therapeutics to inhibit C. albicans dissemination from the gastrointestinal tract in an immunocompromised host as well as the subsequent mortality that can result from disseminated candidiasis.

    Candidiasis is the most common opportunistic infection seen in human immunodeficiency virus (HIV)-infected individuals. The aim of our study was to estimate the candidiasis rate and evaluate its trend in HIV-infected children in Spain during the era of highly active antiretroviral therapy (HAART) compared to HIV-uninfected children. We carried out a retrospective study. Data were obtained from the records of the Minimum Basic Data Set from hospitals in Spain. All HIV-infected children were under 17 years of age, and a group of HIV-uninfected children with hospital admissions matching the study group by gender and age were randomly selected. The follow-up period (1997-2008) was divided into three calendar periods: a) From 1997 to 1999 for early-period HAART; b) from 2000 to 2002 for mid-period HAART; and c) from 2003 to 2008 for late-period HAART. Among children with hospital admissions, HIV-infected children had much higher values than HIV-uninfected children during each of the three calendar periods for overall candidiasis rates (150.0 versus 6.1 events per 1,000 child hospital admissions/year (p candidiasis rate (events per 1,000 HIV-infected children/year) decreased from 1997-1999 to 2000-2002 (18.8 to 10.6; p candidiasis, both non-ICM and ICM rates experienced significant decreases from 1997-1999 to 2003-2008 (15.9 to 5.7 (p candidiasis rate still remains higher than in the general population (from 1997 to 2008), candidiasis diagnoses have decreased among HIV-infected children throughout the HAART era, and it has ceased to be a major health problem among children with HIV infection.

    Full Text Available XML (extensible markup language is becoming the current standard for establishing interoperability on the Web. XML data are self-descriptive and syntax-extensible; this makes it very suitable for representation and exchange of semi-structured data, and allows users to define new elements for their specific applications. As a result, the number of documents incorporating this standard is continuously increasing over the Web. The processing of XML documents may require a traversal of all document structure and therefore, the cost could be very high. A strong demand for a means of efficient and effective XML processing has posed a new challenge for the database world. This paper discusses a fast and efficient indexing technique for XML documents, and introduces the XML graph numbering scheme. It can be used for indexing and securing graph structure of XML documents. This technique provides an efficient method to speed up XML data processing. Furthermore, the paper explores the classification of existing methods impact of query processing, and indexing.

    Full Text Available In this paper we present a method for segmentation of documents image with complex structure. This technique based on GLCM (Grey Level Co-occurrence Matrix used to segment this type of document in three regions namely, 'graphics', 'background' and 'text'. Very briefly, this method is to divide the document image, in block size chosen after a series of tests and then applying the co-occurrence matrix to each block in order to extract five textural parameters which are energy, entropy, the sum entropy, difference entropy and standard deviation. These parameters are then used to classify the image into three regions using the k-means algorithm; the last step of segmentation is obtained by grouping connected pixels. Two performance measurements are performed for both graphics and text zones; we have obtained a classification rate of 98.3% and a Misclassification rate of 1.79%.

The current treatments of vaginal candidiasis usually involve azole-based antifungals, though fungal resistance to these compounds has become prevalent. Therefore, much attention has been given to molecules with antifungal properties from natural sources, such as curcumin (CUR. However, CUR has poor solubility in aqueous solvents and poor oral bioavailability. This study attempted to overcome this problem by developing, characterizing, and evaluating the in vitro antifungal action of a CUR-loaded liquid crystal precursor mucoadhesive system (LCPM for vaginal administration. A low-viscosity LCPM (F consisting of 40% wt/wt polyoxpropylene-(5-polyoxyethylene-(20-cetyl alcohol, 50% wt/wt oleic acid, and 10% wt/wt chitosan dispersion at 0.5% with the addition of 16% poloxamer 407 was developed to take advantage of the lyotropic phase behavior of this formulation. Notably, F could transform into liquid crystal systems when diluted with artificial vaginal mucus at ratios of 1:3 and 1:1 (wt/wt, resulting in the formation of F30 and F100, respectively. Polarized light microscopy and rheological studies revealed that F behaved like an isotropic formulation, whereas F30 and F100 behaved like an anisotropic liquid crystalline system (LCS. Moreover, F30 and F100 presented higher mucoadhesion to porcine vaginal mucosa than F. The analysis of the in vitro activity against Candida albicans revealed that CUR-loaded F was more potent against standard and clinical strains compared with a CUR solution. Therefore, the vaginal administration of CUR-loaded LCPMs represents a

    High doses of micafungin are advocated in neonates with systemic candidiasis, but limited pharmacokinetic (PK) and safety data are available to support their use. Eighteen preterm neonates and infants with systemic candidiasis, three of whom had meningitis, were treated for at least 14 days with 8 to 15 mg/kg of body weight/day of intravenous micafungin. Plasma micafungin concentrations (four measurements for each patient) were determined after the third dose, and the cerebrospinal fluid (CSF) micafungin concentrations in three patients were also obtained. Population PK analyses were used to identify the optimal model, and the model was further validated using external data (n = 5). The safety of micafungin was assessed by measurement of the levels of liver and kidney function biomarkers. The mean age and weight at the initiation of treatment were 2.33 months (standard deviation [SD], 1.98 months) and 3.24 kg (SD, 1.61 kg), respectively. The optimal PK model was one that scaled plasma clearance to weight and the transaminase concentration ratio. The CSF of three patients was sampled, and the observed concentrations were between 0.80 and 1.80 mg/liter. The model-predicted mean micafungin area under the concentration-time curve over 24 h was 336 mg · h/liter (SD, 165 mg · h/liter) with the 10-mg/kg/day dosage. Eighteen of the 23 subjects (78.2%) had clinical resolution of their infection, but 5 had neurologic impairments. Among the transaminases, alkaline phosphatase measurements were significantly higher posttreatment, with a geometric mean ratio of 1.17 (90% confidence interval, 1.01, 1.37). Furthermore, marked elevations in the gamma-glutamyltransferase (GGT) level were observed in three patients treated with 10- to 15-mg/kg/day doses, and improvement of the GGT level was noted after a dose reduction. Higher weight-based doses of micafungin were generally well tolerated in neonates and infants and achieved pharmacokinetic profiles predictive of an effect

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

    The technology developed in this project uses biometric information printed on the document and public key cryptography to ensure that an adversary cannot issue identification documents to unauthorized individuals or alter existing documents to allow their use by unauthorized individuals. This process can be used to produce many types of identification documents with much higher security than any currently in use. The system is demonstrated using a security badge as an example. This project focused on the technologies requiring development in order to make the approach viable with existing badge printing and laminating technologies. By far the most difficult was the image processing required to verify that the picture on the badge had not been altered. Another area that required considerable work was the high density printed data storage required to get sufficient data on the badge for verification of the picture. The image processing process was successfully tested, and recommendations are included to refine the badge system to ensure high reliability. A two dimensional data array suitable for printing the required data on the badge was proposed, but testing of the readability of the array had to be abandoned due to reallocation of the budgeted funds by the LDRD office

    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.

    2018-06-22

    Clinicians are increasingly challenged by patients with refractory vulvovaginal candidiasis (VVC) caused by azole-resistant Candida species. Fluconazole resistant C.albicans is a growing and perplexing problem following years of indiscriminate drug prescription and unnecessary drug exposure and for which there are few therapeutic alternatives. Regrettably, although the azole class of drugs has expanded, new classes of antifungal drugs have not been forthcoming, limiting effective treatment options in patients with azole resistant Candida vaginitis. Areas covered: This review covers published data on epidemiology, pathophysiology and treatment options for women with azole-resistant refractory VVC. Expert opinion: Fluconazole resistant C.albicans adds to the challenge of azole resistant non-albicans Candida spp. Both issues follow years of indiscriminate drug prescription and unnecessary fluconazole exposure. Although an understanding of azole resistance in yeast has been established, this knowledge has not translated into useful therapeutic advantage. Treatment options for such women with refractory symptoms are extremely limited. New therapeutic options and strategies are urgently needed to meet this challenge of azole drug resistance.

    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. PMID:21958417

    Candidiasis is an infectious complication in organ transplant recipients resulting from the patients' immunodeficiency and virulence of fungi pathogens. The purpose of this study was to evaluate the frequency of Candida spp. and identify their presence in the oral lesions of graft recipients. This study included 185 patients, 1.5 to 25.2 years of age (mean = 13.1 +/- 4.2 years) who were receiving combined immunosuppression treatment after kidney or liver transplantation and 70 control subjects. Evaluation included clinical oral examination, mycology, and statistical analysis. Candida spp. colonies were found in the oral mucosa of 63 (34%) graft recipients and in 19 (27%) control subjects. Candida albicans was the most prevalent species. This study showed that, regardless of the type of the organ transplant and immunosuppression, frequent, regular oral follow-up and mycologic tests are recommended. Diagnosing increased density of Candida spp. colonies in the oral cavity will help initiate early antifungal treatment. Candida spp. prevalence in the oral cavity in transplant recipients was higher than in immunocompetent control subjects. Kidney or liver transplantation predisposes one to the development of an increased density of Candida spp. colonies.

    Signaling through the IL-17 receptor (IL-17R) is required to prevent oropharyngeal candidiasis (OPC) in mice and humans. However, the IL-17-responsive cell type(s) that mediate protection are unknown. Using radiation chimeras, we were able to rule out a requirement for IL-17RA in the hematopoietic compartment. We saw remarkable concordance of IL-17-controlled gene expression in C. albicans-infected human oral epithelial cells (OECs) and in tongue tissue from mice with OPC. To interrogate the role of the IL-17R in OECs, we generated mice with conditional deletion of IL-17RA in superficial oral and esophageal epithelial cells (Il17ra ΔK13 ). Following oral Candida infection, Il17ra ΔK13 mice exhibited fungal loads and weight loss indistinguishable from Il17ra -/- mice. Susceptibility in Il17ra ΔK13 mice correlated with expression of the antimicrobial peptide β-defensin 3 (BD3, Defb3). Consistently, Defb3 -/- mice were susceptible to OPC. Thus, OECs dominantly control IL-17R-dependent responses to OPC through regulation of BD3 expression. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background and Purpose: TGF-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in HIV-infected patients. Increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. The aim of this study was to evaluate the plasma levels of TGF-β under in vivo conditions. Materials and Methods: Seventy- two samples were obtained from the oral cavities of HIV-positive Iranian patients and cultured on Sabouraud’s dextrose agar and CHROMagar. Also blood samples were obtained to assess TGF-β levels using ELISA technique. Results: Thirty-three out of 72 oral samples yielded candida isolates, Candida albicans in 14 and non-albicans candida in 19.Fungal infection decreased significantly more TGF-β level than non-fungal infection also HIV negative were significantly more TGF-β than HIV positive. Conclusion: Our findings suggest a significant interaction between fungal infection and HIV on expression of Transforming Growth Factor Beta. PMID:28680977

    An autopsy case of brain candidiasis occurring in a premature infant is presented, and the morphology and intraparenchymal distribution of Candida foci are described in detail with the aid of serial sections of the affected brain. The patient was a boy, who was born after 25 weeks of gestation and died on day 15. Candida foci were composed of two infectious forms of Candida (yeasts and pseudohyphae) and various inflammatory reactions of the host. They were widely disseminated in the brain parenchyma, leptomeninges and ventricular system. In view of their morphology, they were classified into the acute and chronic inflammatory types. The acute type foci, characterized by microabscess of infiltration of neutrophils, were large and localized predominantly in the cerebral white matter, fiber tracts, central grey matter of the midbrain, reticular formation, floor of fourth ventricle and subependymal germinal layer; most of the acute type foci were found in the watershed zones where the blood supply was considered to be poorer than the other parts of the brain parenchyma. In contrast, the chronic type foci, characterized by nodular proliferation of astrocytes, were small and localized in the grey matter (the cerebral cortex, basal ganglia and brainstem nuclei) and the leptomeninges. This study suggests that Candida infection to the brain may occur by different two kinds of way correlating with the proper vasoarchitecture of brain. In addition, it is recommended to make a close examination of the maternal vagina, placenta and umbilical cord after delivery to detect the risk of Candida infection.

    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.

    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.

    Candida spp. represents a group of commensal yeasts that can act as pathogens and cause candidiasis in different anatomical locations. The aim of this study was to perform an epidemiological and comparative analysis between the isolates of Candida spp. in clinical specimens during a three year-period (2010-2012) from children (0-14 years) and adults (15-99 years) in the Valencian Community (RedMIVA). The microbiological surveillance network of Valencian Community was used as the information source. Candida was isolated in 52,436 patients (1,604 [3.1%] children and 50,832 [96.9%] adults). Candida albicans was significantly (p<0.05) the predominant species in both age groups, and in almost every type of clinical specimen. The distribution of other species varied depending on the sample type and age group. In blood specimens, Candida parapsilosis followed by C. albicans, Candida famata and Candida lusitaniae were the main species found in children, whereas C. albicans followed by C. parapsilosis, Candida glabrata and Candida tropicalis were the predominant species in adults. In sterile fluids, urine and lower respiratory tract samples, C. parapsilosis was the second most prevalent species in the children group, while C. glabrata and C. tropicalis were the main second species in adults.

    The ability to tolerate Candida albicans, a human commensal of the gastrointestinal tract and vagina, implicates that host defense mechanisms of resistance and tolerance cooperate to limit fungal burden and inflammation at the different body sites. We evaluated resistance and tolerance to the fungus in experimental and human vulvovaginal candidiasis (VVC) as well as in recurrent VVC (RVVC). Resistance and tolerance mechanisms were both activated in murine VVC, involving IL-22 and IL-10-producing regulatory T cells, respectively, with a major contribution by the enzyme indoleamine 2,3-dioxygenase 1 (IDO1). IDO1 was responsible for the production of tolerogenic kynurenines, such that replacement therapy with kynurenines restored immunoprotection to VVC. In humans, two functional genetic variants in IL22 and IDO1 genes were found to be associated with heightened resistance to RVVC, and they correlated with increased local expression of IL-22, IDO1 and kynurenines. Thus, IL-22 and IDO1 are crucial in balancing resistance with tolerance to Candida, their deficiencies are risk factors for RVVC, and targeting tolerance via therapeutic kynurenines may benefit patients with RVVC.

    It has been suggested that vaginal colonization with lactobacilli may reduce the risk of vulvovaginal candidiasis (VVC), but supporting data are limited. Our objective was to determine the relationship between vaginal bacterial flora and VVC. We conducted a prospective cohort analysis that involved 151 Kenyan sex workers. At monthly follow-up visits, VVC was defined as the presence of yeast buds, pseudohyphae, or both on a wet preparation (including potassium hydroxide preparation) of vaginal secretions. Generalized estimating equations were used to identify correlates of VVC. Participants returned for a median of 12 visits (interquartile range, 11-12 visits). VVC was identified at 162 visits, including 26 involving symptomatic VVC. Bacterial vaginosis was associated with fewer episodes of VVC (adjusted odds ratio [aOR], 0.29 [95% confidence interval {CI}, 0.16-0.50]). After excluding women with concurrent bacterial vaginosis, another possible cause of vaginal symptoms, the likelihood of symptomatic VVC was higher among those who had had yeast identified on wet preparation of vaginal secretions during the past 60 days (aOR, 4.06 [95% CI, 1.12-14.74]) and those with concurrent vaginal Lactobacillus colonization (aOR, 3.75 [95% CI, 1.30-10.83]). Contrary to the commonly posited hypothesis that vaginal Lactobacillus colonization has a protective effect, we found that such colonization was associated with a nearly 4-fold increase in the likelihood of symptomatic VVC.

    Vulvovaginal candidiasis (VVC) is one of the most prevalent vaginal infectious diseases, and there are controversial reports regarding the diversity of the associated vaginal microbiota. We determined the vaginal microbial community in patients with VVC, bacterial vaginosis (BV), and mixed infection of VVC and BV using Illumina sequencing of 16S rRNA tags. Our results revealed for the first time the highly variable patterns of the vaginal microbiome from VVC patients. In general, the alpha-diversity results of species richness and evenness showed the following order: normal control vaginal microbiota of VVC is complex. The mixed BV and VVC infection group showed a unique pattern, with a relatively higher abundance of Lactobacillus than the BV group and higher abundance of Prevotella, Gardnerella, and Atopobium than the normal control. In contrast, the VVC-only group could not be described by any single profile, ranging from a community structure similar to the normal control (predominated with Lactobacillus) to BV-like community structures (abundant with Gardnerella and Atopobium). Treatment of VVC resulted in inconsistent changes of the vaginal microbiota, with four BV/VVC samples recovering to a higher Lactobacillus level, whereas many VVC-only patients did not. These results will be useful for future studies on the role of vaginal microbiota in VVC and related infectious diseases.

    Full Text Available Propolis, a resinous compound produced by Apis mellifera L. bees, is known to possess a variety of biological activities and is applied in the therapy of various infectious diseases. The aim of this study was to evaluate the in vitro antifungal activity of propolis ethanol extract (PE and propolis microparticles (PMs obtained from a sample of Brazilian propolis against clinical yeast isolates of importance in the vulvovaginal candidiasis (VVC. PE was used to prepare the microparticles. Yeast isolates (n=89, obtained from vaginal exudates of patients with VVC, were exposed to the PE and the PMs. Moreover, the main antifungal drugs used in the treatment of VVC (Fluconazole, Voriconazole, Itraconazole, Ketoconazole, Miconazole and Amphotericin B were also tested. Minimum inhibitory concentration (MIC was determined according to the standard broth microdilution method. Some Candida albicans isolates showed resistance or dose-dependent susceptibility for the azolic drugs and Amphotericin B. Non-C. albicans isolates showed more resistance and dose-dependent susceptibility for the azolic drugs than C. albicans. However, all of them were sensitive or dose-dependent susceptible for Amphotericin B. All yeasts were inhibited by PE and PMs, with small variation, independent of the species of yeast. The overall results provided important information for the potential application of PMs in the therapy of VVC and the possible prevention of the occurrence of new symptomatic episodes.

    Neutrophil gelatinase-associated lipocalin (NGAL) is a component of innate immunity that prevents iron uptake by microorganisms. We evaluated whether NGAL was present in vaginal fluid and whether concentrations were altered in women with bacterial vaginosis (BV) or vulvovaginal candidiasis (VVC). Vaginal secretions from 52 women with VVC, 43 with BV, and 77 healthy controls were assayed by enzyme-linked immunosorbent assay for NGAL and for concentrations of L-lactic acid. The median concentration of NGAL in vaginal fluid was significantly higher in control women (561 pg/mL) than in women with BV (402 pg/mL; P = .0116) and lower in women with VVC (741 pg/mL; P = .0017). Median lactic acid levels were similar in controls (0.11 mmol/L) and women with VVC (0.13 mmol/L) and were lower in women with BV (0.02 mmol/L; P vaginal NGAL levels that might facilitate the growth of bacteria associated with BV. © The Author(s) 2015.

    Vulvovaginal candidiasis is a mucosal infection affecting many women, but the immune mechanisms operating against Candida albicans at the mucosal level remain unknown. A rat model was employed to further characterize the contribution of B and T cells to anti-Candida vaginal protection. Particularly, the protective role of vaginal B cells was studied by means of adoptive transfer of vaginal CD3(-) CD5(+) IgM(+) cells from Candida-immunized rats to naïve animals. This passive transfer of B cells resulted into a number of vaginal C. albicans CFU approximately 50% lower than their controls. Sorted CD3(-) CD5(+) IgM(+) vaginal B lymphocytes from Candida-infected rats proliferated in response to stimulation with an immunodominant mannoprotein (MP) antigen of the fungus. Importantly, anti-MP antibodies and antibody-secreting B cells were detected in the supernatant and cell cultures, respectively, of vaginal B lymphocytes from infected rats incubated in vitro with vaginal T cells and stimulated with MP. No such specific antibodies were found when using vaginal B cells from uninfected rats. Furthermore, inflammatory and anti-inflammatory cytokines, such as interleukin-2 (IL-2), IL-6 and IL-10, were found in the supernatant of vaginal B cells from infected rats. These data are evidence of a partial anti-Candida protective role of CD3(-) CD5(+) IgM(+) vaginal B lymphocytes in our experimental model.

    To evaluate the frequency of yeast, bacteria or protozoa in pregnant women and to correlate the possible associations of these microorganisms and their relationships with vulvovaginitis (VV) and cervicitis. Vaginal specimens were collected and prepared for smears in microscope slides for the evaluation of yeast, Trichomonas vaginalis and bacteria. Samples were cultured in specific culture medium. Cervical specimens were used to investigate the presence of Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma spp. and Mycoplasma hominis. We enrolled 210 pregnant women, aged 10-42 years old. Of them, 38.1% were symptomatic. Symptoms were most prevalent in the second and third trimesters of pregnancy coincident with a major prevalence of microorganisms. In this study, 39.5% of pregnant women had normal microbial biota and symptoms of VV due to non-infectious causes were observed (6.2%). The occurrence of vulvovaginal candidiasis was 25% and Candida albicans with a prevalence of 80.7% was the dominant species (P = 0.005) while non-albicans Candida species and other yeast were more common in asymptomatic ones (P = 0.0038). The frequency of bacterial vaginosis, T. vaginalis, C. trachomatis and N. gonorrhoeae were 18.1%, 1.4, 1.4% and 0.5% respectively. © 2016 Blackwell Verlag GmbH.

    The recognition of β-glucans by dectin-1 has been shown to mediate cell activation, cytokine production and a variety of antifungal responses. Here, we report that the functional activity of dectin-1 in mucosal immunity to Candida albicans is influenced by the genetic background of the host. Dectin-1 was required for the proper control of gastrointestinal and vaginal candidiasis in C57BL/6, but not BALB/c mice; in fact, the latter showed increased resistance in the absence of dectin-1. The susceptibility of dectin-1-deficient C57BL/6 mice to infection was associated with defects in IL-17A and aryl hydrocarbon receptor-dependent IL-22 production and in adaptive Th1 responses. In contrast, the resistance of dectin-1-deficient BALB/c mice was associated with increased IL-17A and IL-22 production and the skewing towards Th1/Treg immune responses that provide immunological memory. Disparate canonical/noncanonical NF-κB signaling pathways downstream of dectin-1 were activated in the two different mouse strains. Thus, the net activity of dectin-1 in antifungal mucosal immunity is dependent on the host's genetic background, which affects both the innate cytokine production and the adaptive Th1/Th17 cell activation upon dectin-1 signaling.

    INTRODUCTION--Although as many as 5% of all women complain of chronic vulvovaginitis, little is known about these women. They may often be misdiagnosed and the role of vaginal yeast culture in diagnosing vulvovaginal candidiasis (VVC) among them has not been clearly defined. METHODS--To address these deficiencies, we tabulated initial diagnoses among new patients and conducted a medical record-based, unmatched case-control study among women reporting a history of chronic vulvovaginitis (four or more episodes in the past year) at a vulvovaginitis specialty clinic. Clinical presentation and medical history were compared for women who had a positive vaginal yeast culture for either Candida albicans or C glabrata, or who had a negative culture. RESULTS--One-third of the women had no apparent vulvovaginal disease at their initial visit. All women reported similar symptoms, except for an increased prevalence of painful sexual intercourse in women with C albicans (chi 2 p = 0.014 versus women with C glabrata and p vulvovaginitis. Among women with VVC, subtle differences in clinical presentation do not reliably distinguish women with C albicans from those with C glabrata. Our study also indicates that vaginal yeast cultures, while not necessary for every patient, are valuable in confirming negative diagnoses, detecting microscopy false-negatives, and identifying non-C albicans isolates.

    In this work, chitosan films were prepared by a casting/solvent evaporation methodology using pectin or hydroxypropylmethyl cellulose to form polymeric matrices. Miconazole nitrate, as a model drug, was loaded into such formulations. These polymeric films were characterized in terms of mechanical properties, adhesiveness, and swelling as well as drug release. Besides, the morphology of raw materials and films was investigated by scanning electron microscopy; interactions between polymers were analyzed by infrared spectroscopy and drug crystallinity studied by differential scanning calorimetry and X-ray diffraction. In addition, antifungal activity against cultures of the five most important fungal opportunistic pathogens belonging to Candida genus was investigated. Chitosan:hydroxypropylmethyl cellulose films were found to be the most appropriate formulations in terms of folding endurance, mechanical properties, and adhesiveness. Also, an improvement in the dissolution rate of miconazole nitrate from the films up to 90% compared to the non-loaded drug was observed. The in vitro antifungal activity showed a significant activity of the model drug when it is loaded into chitosan films. These findings suggest that chitosan-based films are a promising approach to deliver miconazole nitrate for the treatment of candidiasis.

    Google Glass is, in essence, a smartphone in the form of a pair of spectacles. It has a display system, a bone conduction "speaker," video camera, and connectivity via WiFi or Bluetooth technologies. It can also be controlled by voice command. Seizing Google Glass' capabilities as windows of opportunity, surgeons have been the first group of doctors trying to incorporate the technology into their daily practices. Experiences from different groups have demonstrated Google Glass' potential in improving perioperative care, intraoperative communication and documentation, surgical outcome as well as surgical training. On the other hand, the device has technical limitations, notably suboptimal image qualities and a short battery life. Its operational functions also bring forth concerns on the protection of patient privacy. Nonetheless, the technological advances that this device embodies hold promises in surgical innovations. Further studies are required, and surgeons should explore, investigate, and embrace similar technologies with keen and informed anticipation. © The Author(s) 2016.

    The United States Strategic Petroleum Reserve (SPR) maintains an underground storage system consisting of caverns that were leached or solution mined in four salt domes located near the Gulf of Mexico in Texas and Louisiana. The SPR comprises more than 60 active caverns containing approximately 700 million barrels of crude oil. Sandia National Labo- ratories (SNL) is the geotechnical advisor to the SPR. As the most pressing need at the inception of the SPR was to create and fill storage volume with oil, the decision was made to leach the caverns and fill them simultaneously (leach-fill). Therefore, A.J. Russo developed SANSMIC in the early 1980s which allows for a transient oil-brine interface (OBI) making it possible to model leach-fill and withdrawal operations. As the majority of caverns are currently filled to storage capacity, the primary uses of SANSMIC at this time are related to the effects of small and large withdrawals, expansion of existing caverns, and projecting future pillar to diameter ratios. SANSMIC was identified by SNL as a priority candidate for qualification. This report continues the quality assurance (QA) process by documenting the "as built" mathematical and numerical models that comprise this document. The pro- gram flow is outlined and the models are discussed in detail. Code features that were added later or were not documented previously have been expounded. No changes in the code's physics have occurred since the original documentation (Russo, 1981, 1983) although recent experiments may yield improvements to the temperature and plume methods in the future.
