RESUMO
BACKGROUND: We report two cases of fungal endophthalmitis induced by Candida species identified based on internal transcribed spacer 1 (ITS1) sequencing. CASE PRESENTATION: In two cases, endophthalmitis was suspected, and the patients underwent pars plana vitrectomy. Case 1 was a 64-year-old woman with a history of cataract surgery 10 days prior. She had a history of anal primary melanoma, which metastasized throughout the body and subsequently relapsed. Vitreous culture and ITS-1 deep sequencing revealed the presence of the rare fungus, Candida dubliniensis. Case 2 was a 54-year-old man with a history of liver cancer and kidney failure. Culture methods and ITS1 deep sequencing both revealed the presence of Candida albicans. Both patients exhibited good visual prognoses after treatment with topical and systemic antibiotics. CONCLUSIONS: We present two cases of fungal endophthalmitis caused by two Candida species identified by both the culture method and ITS1 deep sequencing. The fungal pathogen was identified by ITS deep sequencing three days after sample submission; the culture method yielded results after 1 week. These findings support the applicability of ITS1 sequencing for timely pathogen identification for cases of fungal endophthalmitis and provide detailed taxonomic information at the species level.

Feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) is a rare and poorly understood disease characterised by the infiltration of eosinophils and the development of fibrous tissue within the gastrointestinal tract of cats. A 2-year-old female neutered Ragdoll was presented for signs consistent with extrahepatic biliary tract obstruction (EHBO), including jaundice, hyporexia and lethargy. Marked progressive hyperbilirubinemia and mild anaemia were also present. Abdominal ultrasonography suggested a duodenal mass and pancreatitis as the cause of EHBO. Cytopathological results from fine needle aspirates detected mast cells and eosinophils in the duodenal mass and eosinophils in the spleen and the liver, suggestive of a possible mast cell tumour. A cholecystojejunostomy and a duodenotomy were performed to divert the biliary outflow and obtain biopsy samples, respectively. Eosinophilic sclerosing fibroplasia in the duodenal mass and fungal elements in an abdominal lymph node were reported on histopathological examination. A pan-fungal PCR targeting ITS2 performed on DNA extracted from an abdominal lymph node detected Candida albicans. This report adds to the growing body of evidence that FGESF can occur in association with fungal infections.

Candida albicans is the most common agent in human fungal infections; nevertheless, in the last decades, the closely related yeasts Candida dubliniensis and Candida africana have emerged as pathogens. The purpose of this study was to compare tobacco agar with another five agars prepared from plant extracts (Origanum vulgare, Rosmarinus officinalis, Solanum rudepannum, Solanum oblongifolium and Brugmansia arborea) on the differentiation of C. albicans complex. The hyphae and chlamyconidia formation and the color and margin of the colonies of 200 clinical isolates of C. albicans, C. dubliniensis and C. africana were evaluated. After seven days of incubation at 28 °C, Tobacco agar, S. rudepannum and B. arborea agars allowed the differentiation of 100 % C. dubliniensis. Additionally, 24% of C. africana isolates produced brownish colonies in the medium prepared from Rosmarinus officinalis (rosemary) extract. These results indicate that S. rudepannun, B. arborea and rosemary agar could be used as screening for the phenotypic differentiation between the species of C. albicans complex. Rosemary agar could be used to aid in the differentiation of C. albicans from C. africana. These culture media based on plants, could be used as simple and inexpensive screening methods in the phenotypic differentiation of C. dubliniensis and C. africana.

Recurrent pleural effusions are associated with significant morbidity and mortality. Pleural effusions are frequently seen in patients with chronic renal failure due to fluid retention. Pleural effusions in renal transplant patients are usually related to secondary pulmonary infections, surgical complications, drug toxicities, or post-transplant lymphoproliferative disorder (PTLD). We describe an unusual cause of recurrent pleural effusion attributed to fungal infection in a transplanted kidney due to activation of the renin-angiotensin-aldosterone system (RAAS), successfully treated with antifungal medications that led to complete resolution of pleural effusion.

THE AIM OF THE STUDY: The study by the method of tissue polymerase chain reaction of the species composition of the microbiota of lesions of the oral mucosa in patients with bullous lesions. MATERIAL AND METHODS: Biopsy specimens of the oral mucosa of 51 patients were studied by the polymerase chain reaction method, of which 14 patients with pemphigus vulgaris, 17 patients with pemphigoid bullosa, and 20 patients with the bullous form of ruber lichen planus. 4 types of microorganisms have been identified - Fusobacterium, Streptococcus pneumoniae, Candida albicans, Ureaplasma spp. and viruses - Human Papillomavirus 16, Epstein-Barr virus and Citomegalovirus. RESULTS: In the study of the microbiota of bullous lesions, associations of microorganisms and viruses were established in a significant number of cases. Associations of Str.pneumoniae and C. albicans were quite common in patients with pemphigus vulgaris in 26.3%, pemphigoid bullosa in 20.0%, and in patients with the bullous form of ruber lichen planus in 14.3% of cases. In patients with pemphigus vulgaris, the association of Str.pneumoniae, C. albicans and EBV was noted in 31.6% of cases. In patients with the bullous form of ruber lichen planus in a high percentage of cases (28.6%), the associations of Str. pneumoniae, EBV and CMV. CONCLUSION: Identification at earlier stages of management of patients with bullous lesions Str. pneumoniae, Candida albicans, and Fusobacterium associated with herpes viruses should be regarded as one of the triggering mechanisms of an autoimmune conflict, which subsequently causes a specific clinical picture of these diseases.

INTRODUCTION: Resistance to azole drugs has been observed in candidiasis due to their long-term use and poor response to treatment. Resistance to azole drugs in Candida albicans isolates is controlled by several genes including ERG11, CDR1, CDR2, and MDR1. In this study, the expression of the mentioned genes was evaluated in C. albicans isolates susceptible and resistant to fluconazole. METHODS: After identifying the Candida isolates using morphological and molecular methods, the minimum inhibitory concentration (MIC) and drug susceptibility were determined using the European Committee on Antimicrobial Susceptibility Testing (EUCAST) method. RNA was then extracted and cDNA was synthesized from 24 C. albicans isolates from patients with cancer. Then, the mean expressions of these genes were compared in two groups using real-time polymerase chain reaction (RT-PCR). RESULTS: A total of 74 Candida isolates were obtained from the oral cavity of 61 cancer patients with oral candidiasis. After 24 h, 21.6% of the isolates were fluconazole-resistant, 10.8% were identified as dose-dependent, and the rest of the isolates (67.6%) were fluconazole-sensitive. The mean expressions of the CDR1 and MDR1 genes were significantly higher in the resistant isolates than in the sensitive ones. However, the ERG11 and CDR2 genes were not significantly increased in the resistant isolates. CONCLUSION: The increased mean expressions of the CDR1 and MDR1 genes had a greater effect on fluconazole resistance among the drug-resistant strains of C. albicans in chemotherapy patients. It seemed that the accumulation of chemotherapeutic drugs in this organism stimulated some regulatory factors and increased the expression of these two genes and ultimately helped to further increase their expression and resistance to fluconazole.

Smoking and Candida albicans (C. albicans) infection are risk factors for many oral diseases. Several studies have reported a close relationship between smoking and the occurrence of C. albicans infection. However, the exact underlying mechanism of this relationship remains unclear. We established a rat infection model and a C. albicans-Leuk1 epithelial cell co-culture model with and without smoke exposure to investigate the mechanism by which smoking contributes to C. albicans infection. Oral mucosa samples from healthy individuals and patients with oral leucoplakia were also analysed according to their smoking status. Our results indicated that smoking induced oxidative stress and redox dysfunction in the oral mucosa. Smoking-induced Nrf2 negatively regulated the NLRP3 inflammasome, impaired the oral mucosal defence response and increased the oral mucosa susceptibility to C. albicans. The results suggest that the Nrf2 pathway could be involved in the pathogenesis of oral diseases by mediating an antioxidative response to cigarette smoke exposure and suppressing host immunity against C. albicans.

While pathogens can be deadly to humans, many of them cause a range of infection types with non-lethal phenotypes. Candida albicans, an opportunistic fungal pathogen of humans, is the fourth most common cause of nosocomial infections which results in ~40% mortality. However, other C. albicans infections are less severe and rarely lethal and include vulvovaginal candidiasis, impacting ~75% of women, as well as oropharyngeal candidiasis, predominantly impacting infants, AIDS patients and cancer patients. While murine models are most frequently used to study C. albicans pathogenesis, these models predominantly assess host survival and are costly, time consuming, and limited in replication. Therefore, several mini-model systems, including Drosophila melanogaster, Danio rerio, Galleria mellonella, and Caenorhabditis elegans, have been developed to study C. albicans. These mini-models are well-suited for screening mutant libraries or diverse genetic backgrounds of C. albicans. Here we describe two approaches to study C. albicans infection using C. elegans. The first is a fecundity assay which measures host reproduction and monitors survival of individual hosts. The second is a lineage expansion assay which measures how C. albicans infection affects host population growth over multiple generations. Together, these assays provide a simple, cost-effective way to quickly assess C. albicans virulence.

BACKGROUND: Prosthetic joint infection (PJI) is one of the most feared complications following total arthroplasty surgeries. Gram-positive bacteria are the most common microorganisms implicated in PJIs, while infections mediated by fungi only account for 1% of cases. When dealing with PJIs, a two-stage revision arthroplasty is widely used. Briefly, a spacer is introduced until re-implantation of the definitive prosthesis to provide skeleton stabilization while delivering antibiotics in the site of the infection. Sometimes, antimicrobial therapy may fail, but the isolation of a second microorganism from the spacer is uncommon and even less frequent that of a yeast. CASE PRESENTATION: Here is described a case of a 75-year-old woman who underwent two-stage revision surgery of the left hip prosthesis secondary to a Staphylococcus capitis infection, whose spacer was found to be infected by Candida albicans at a later time. Briefly, the patient underwent revision surgery of the hip prosthesis for a suspected PJI. After the debridement of the infected tissue, an antibiotic-loaded spacer was implanted. The microbiological analysis of the periprosthetic tissues and the implant depicted a S. capitis infection that was treated according to the antimicrobial susceptibility profile of the clinical isolate. Three months later, the patient was admitted to the emergency room due to local inflammatory signs. Synovial fluid was sent to the laboratory for culture. No evidence of S. capitis was detected, however, a yeast was identified as Candida albicans. Fifteen days later, the patient was hospitalized for the removal of the infected spacer. Microbiological cultures confirmed the results of the synovial fluid analysis. According to the susceptibility profile, the patient was treated with fluconazole (400 mg/day) for 6 months. Seven months later, the patient underwent second-stage surgery. The microbiological tests on the spacer were all negative. After 12 months of follow-up, the patient has fully recovered and no radiological signs of infection have been detected. CONCLUSIONS: Given the exceptionality of this complication, it is important to report these events to better understand the clinical outcomes after the selected therapeutic options to prevent and forestall the development of either bacterial or fungal spacer infections.

RATIONALE: Endogenous fungal endophthalmitis (EFE) is a sight-threatening complication of systemic fungemia. As the prevalence rises, treatment remains a challenge especially when there is a failure in first-line treatment or drug-resistant fungus. This case report studies a case of chronic EFE, focusing on the diagnostic procedures, treatment options, monitoring parameters and the treatment outcome. PATIENT CONCERNS: A 64-year-old man with underlying well controlled diabetes mellitus was treated with 2 weeks' course of intravenous antifungal fluconazole for pyelonephritis as his blood culture grew Candida albicans. Concurrently, he complained of 3 months of bilateral painless progressive blurring of vision. At presentation, his visual acuity (VA) was light perception both eyes. Ocular examination revealed non granulomatous inflammation with dense vitritis of both eyes. DIAGNOSIS: He was diagnosed with EFE but the condition responded poorly with the medications. INTERVENTIONS: He was treated with intravitreal (IVT) amphotericin B and fluconazole was continued. Vitrectomy was performed and intraoperative findings included bilateral fungal balls in the vitreous and retina with foveal traction in the left eye. Postoperatively, vision acuity was 6/24, N8 right eye and 2/60, N unable for left eye with extensive left macular scar and hole. Vitreous cultures were negative. He received multiple IVT amphotericin B and was started on topical steroid eye drops for persistent panuveitis with systemic fluconazole. Ocular improvement was seen after switching to IVT and topical voriconazole. Despite this, his ocular condition deteriorated and he developed neovascular glaucoma requiring 3 topical antiglaucoma agents. Panretinal photocoagulation was subsequently performed. OUTCOMES: At 3âmonths' follow-up, his vision acuity remained at 6/24 for right eye and 2/60 for the left eye. There was no recurrence of inflammation or infection in both eyes. LESSONS: Voriconazole could serve as a promising broad spectrum tri-azole agent in cases of failure in first-line treatment or drug-resistant fungus.

BACKGROUND: Candida bloodstream infections (BSI) became an important invasive disease in the late 20th century, in particular among immunocompromised patients. Although considerable progress has been made in the management of patients with invasive mycoses, Candida BSI are still widespread among hospitalised patients and are associated with relatively high mortality. OBJECTIVES: We conducted a retrospective study to evaluate patient characteristics, incidence, species distribution and antifungal susceptibility of BSI isolates of Candida spp. as well as outcomes of Candida BSI from 2001 to 2012, before the widespread use of echinocandins. This is the first epidemiological study of Candida BSI in Slovenia so far. METHODS: All documented candidaemia cases from 2001 to 2012 in two major hospitals-University Medical Centre and Institute of Oncology in Ljubljana, Slovenia-were taken into consideration. Candida BSI were identified in 422 patients (250 male, 172 female). Laboratory and clinical data of these patients were retrospectively analysed. Mann-Whitney U test was used to compare continuous variables and Fisher's exact test or chi-squared test for categorical variables. RESULTS AND CONCLUSIONS: The average incidence of Candida BSI was 0.524/10.000 patient-days (0,317/1000 admissions); 16/422 were younger than 1 year and 251/422 patients were over 60 years old. The most commonly isolated species were Candida albicans and Candida glabrata, followed by Candida parapsilosis. Majority of the patients had a single episode of Candida BSI, multiple episodes of Candida BSI occurred in 18/434 patients (4.1%); in 25/434 patients (5.8%) mixed Candida BSI were observed. Crude 30-day case-fatality rate was 55.4%.

BACKGROUND: Invasive candidiasis is the most common fungal disease among hospitalized patients and continues to be a major cause of mortality. Risk factors for mortality have been studied previously but rarely developed into a predictive nomogram, especially for cancer patients. We constructed a nomogram for mortality prediction based on a retrospective review of 10 years of data for cancer patients with invasive candidiasis. METHODS: Clinical data for cancer patients with invasive candidiasis during the period of 2010-2019 were studied; the cases were randomly divided into training and validation cohorts. Variables in the training cohort were subjected to a predictive nomogram based on multivariate logistic regression analysis and a stepwise algorithm. We assessed the performance of the nomogram through the area under the receiver operating characteristic (ROC) curve (AUC) and decision curve analysis (DCA) in both the training and validation cohorts. RESULTS: A total of 207 cases of invasive candidiasis were examined, and the crude 30-day mortality was 28.0%. Candida albicans (48.3%) was the predominant species responsible for infection, followed by the Candida glabrata complex (24.2%) and Candida tropicalis (10.1%). The training and validation cohorts contained 147 and 60 cases, respectively. The predictive nomogram consisted of bloodstream infections, intensive care unit (ICU) admitted > 3 days, no prior surgery, metastasis and no source control. The AUCs of the training and validation cohorts were 0.895 (95% confidence interval [CI], 0.846-0.945) and 0.862 (95% CI, 0.770-0.955), respectively. The net benefit of the model performed better than "treatment for all" in DCA and was also better for opting low-risk patients out of treatment than "treatment for none" in opt-out DCA. CONCLUSION: Cancer patients with invasive candidiasis exhibit high crude mortality. The predictive nomogram established in this study can provide a probability of mortality for a given patient, which will be beneficial for therapeutic strategies and outcome improvement.

Fungal endocarditis, specifically from Candida species, is a rare but serious infection with a high mortality rate. Most cases occur in bioprosthetic or mechanical valves and are uncommon in native, structurally normal valves. When Candida endocarditis is detected and appropriate treatment is initiated earlier, there is an improvement in mortality. While the recommendation is usually to treat with a combination of surgery and antifungal medications, patient comorbidities may limit treatment options.

SUMMARY: Biologic mesh is preferred over synthetic mesh for complex and contaminated abdominal wall repairs; however, there are very little data on the risks and complications associated with its use. We report the case of a 67-year-old man with failed synthetic mesh repair for recurrent ventral hernia, who subsequently required an abdominal wall reconstruction (AWR), including the intraperitoneal sublay of noncrosslinked biologic mesh. His postoperative course was complicated with catastrophic sepsis and sustained hemodynamic instability, responding only to mesh explantation. The biologic mesh was subsequently noted to be histologically infected with invasive Candida albicans. Although noncrosslinked biologic mesh is a valuable adjunct to AWR, it is not infection-resistant. Although it is rare, infection of any foreign tissue, including biologic mesh, can occur in the setting of complex ventral abdominal wall repairs. Clinicians should be watchful for such infections in complex repairs as they may require biologic mesh explantation for clinical recovery.

Oral candidiasis are among the most common noncommunicable diseases, related with serious local and systemic illnesses. Although these infections can occur in all kinds of patients, they are more recurrent in immunosuppressed ones such as patients with HIV, hepatitis, cancer or under long antimicrobial treatments. Candida albicans continues to be the most frequently identified Candida spp. in these disorders, but other non-C. albicans Candida are rising. Understanding the immune responses involved in oral Candida spp. infections is a key feature to a successful treatment and to the design of novel therapies. In this review, we performed a literature search in PubMed and WoS, in order to examine and analyze common oral Candida spp.-bacteria/Candida-Candida interactions and the host immunity response in oral candidiasis.

There is a scarcity of studies on the prevalence of Trichomonas vaginalis (TV) in indigenous populations of Brazil. We conducted a cross-sectional study between January and December 2018, on indigenous women living nearby an urban center of the Midwest region of Brazil and determined the prevalence of TV. Factors associated with TV infection and a comparison of molecular and direct microscopy diagnoses were determined. 241 indigenous women aged above 18 years participated in the study. Cervical and vaginal brush samples were collected to diagnose TV through polymerase chain reaction (PCR). Direct microscopy for detection of TV, and cellular changes was performed. A sociodemographic and behavioral questionnaire was applied at the beginning of the study. All the data were analyzed using Statistical Package for the Social Sciences. The result obtained showed that 27.8% [95% CI: 22.2-33.9] were positive for TV on PCR, while 7.41% [95% CI: 4.1-11] showed positive on direct microscopy. Direct microcopy also found 21 (8.71%) and 8 (3.31%) women infected with Gardnerella vaginalis and Candida albicans, respectively. In addition, 10 women presented atypical squamous cells of unknown significance and 14 lesions suggestive of HPV. Single women, under the age of 30 and who do not use condoms, were found to have a greater chance of getting TV infection. The high prevalence TV found in this population is comparable to highly vulnerable populations, as prisoners, sex workers and women in regions with low socioeconomic levels, moreover, seems to be an underdiagnosis of this infection. Therefore, a routine test program, as well as a review of the diagnostic method used, is encouraged for proper management.

Retrospective descriptive study carried out to determine the characteristics of fungemia in 285 cancer patients hospitalized from 2012 to 2016 at the Instituto Nacional de Enfermedades Neoplásicas (INEN). Demographic, clinical and microbiological information was evaluated. Fungemia by C. albicans predominated in patients with solid tumors and without neutropenia, while those caused by C. tropicalis predominated in patients with hematological neoplasia and neutropenia. C. tropicalis was the agent isolated in most cases (47.0%). Fungemia increased over time in patients without neutropenia. Fungemia caused by C. albicans increases with age in patients with solid tumors without neutropenia. It is concluded that fungemia are mainly caused by C. tropicalis in patients with hematological neoplasia with neutropenia and by C. albicans in patients with solid tumors without neutropenia. In addition, fungemia in patients without neutropenia increases over time; and those caused by C. albicans increase with age in patients with solid tumors without neutropenia.
Con el objetivo de conocer las características de las fungemias en 285 pacientes oncológicos hospitalizados del 2012 al 2016 en el Instituto Nacional de Enfermedades Neoplásicas se realizó un estudio descriptivo retrospectivo. Se evaluó información demográfica, clínica y microbiológica. Las fungemias por C. albicans predominaron en pacientes con tumores sólidos y sin neutropenia, mientras las causadas por C. tropicalis predominaron en pacientes con neoplasias hematológicas y neutropenia. C. tropicalis fue el agente más aislado (47,0%). Las fungemias aumentaron con el tiempo en los pacientes sin neutropenia. Las fungemias causadas por C. albicans aumentan con la edad en pacientes con tumores sólidos sin neutropenia. Se concluye que las fungemias son mayormente causadas por C. tropicalis en pacientes con neoplasias hematológicas con neutropenia y por C. albicans en pacientes con tumores sólidos sin neutropenia. Además, las fungemias en pacientes sin neutropenia aumentan en el tiempo y las causadas por C. albicans, en tumores sólidos sin neutropenia, aumentan con la edad.
