Abstract
Human fungal diseases are infections caused by any fungus that invades human tissues, causing superficial, subcutaneous, or systemic diseases. Fungal infections that enter various human tissues and organs pose a significant threat to millions of individuals with weakened immune systems globally. Over recent decades, the reported cases of invasive fungal infections have increased substantially and research progress in this field has also been rapidly boosted. This review provides a comprehensive list of human fungal pathogens extracted from over 850 recent case reports, and a summary of the relevant disease conditions and their origins. Details of 281 human fungal pathogens belonging to 12 classes and 104 genera in the divisions ascomycota, basidiomycota, entomophthoromycota, and mucoromycota are listed. Among these, Aspergillus stands out as the genus with the greatest potential of infecting humans, comprising 16 species known to infect humans. Additionally, three other genera, Curvularia, Exophiala, and Trichophyton, are recognized as significant genera, each comprising 10 or more known human pathogenic species. A phylogenetic analysis based on partial sequences of the 28S nrRNA gene (LSU) of human fungal pathogens was performed to show their phylogenetic relationships and clarify their taxonomies. In addition, this review summarizes the recent advancements in fungal disease diagnosis and therapeutics.

Abstract
Paracoccidioidomycosis is a systemic mycosis found mainly in South America and is the most prevalent endemic and systemic mycosis in Brazil. The purpose of this paper was to report the case of a male patient who developed peritonitis caused by Paracoccidioides spp. Forty-eight-year-old, male patient, with type I Diabetes mellitus and chronic kidney disease who was undergoing a Continuous Ambulatory Peritoneal Dialysis (CAPD) program. After eighteen months of peritoneal dialysis, the patient developed turbidity of the peritoneal fluid and was diagnosed with peritonitis. Direct mycological examination of the peritoneal fluid revealed yeasts with morphology suggestive of Paracoccidioides spp. The patient was treated with sulfamethoxazole-trimethoprim (1,600 mg/320 mg dose/day) for 61 days, but he died because a bacterial septic shock. The diagnosis of opportunistic PCM peritonitis was later confirmed by autopsy and Paracoccidioides spp. isolation. This is the first reported case of a patient on CAPD who experienced complications due peritonitis caused by opportunistic PCM.

Interactions of Candida tropicalis pH-related antigen 1 with complement proteins C3, C3b, factor-H, C4BP and complement evasion. Immunobiology 2023; 228:152303.

Abstract
Candida, as a part of the human microbiota, can cause opportunistic infections that are either localised or systemic candidiasis. Emerging resistance to the standard antifungal drugs is associated with increased mortality rate due to invasive Candida infections, particularly in immunocompromised patients. While there are several species of Candida, an increasing number of Candida tropicalis isolates have been recently reported from patients with invasive candidiasis or inflammatory bowel diseases. In order to establish infections, C. tropicalis has to adopt several strategies to escape the host immune attack. Understanding the immune evasion strategies is of great importance as these can be exploited as novel therapeutic targets. C. albicans pH-related antigen 1 (CaPra1), a surface bound and secretory protein, has been found to interact strongly with the immune system and help in complement evasion. However, the role of C. tropicalis Pra1 (CtPra1) and its interaction with the complement is not studied yet. Thus, we characterised how pH-related antigen 1 of C. tropicalis (CtPra1) interacts with some of the key complement proteins of the innate immune system. CtPra1 was recombinantly produced using a Kluyveromyces lactis yeast expression system. Recombinant CtPra1, was found to bind human C3 and C3b, central molecules of the complement pathways that are important components of the innate immune system. It was also found to bind human complement regulatory proteins factor-H and C4b-binding protein (C4BP). CtPra1-factor-H and CtPra1-C4BP interactions were found to be ionic in nature as the binding intensity affected by high sodium chloride concentrations. CtPra1 inhibited functional complement activation with different effects on classical (∼20 %), lectin (∼25 %) and alternative (∼30 %) pathways. qPCR experiments using C. tropicalis clinical isolates (oral, blood and peritoneal fluid) revealed relatively higher levels of expression of CtPra1 gene when compared to the reference strain. Native CtPra1 was found to be expressed both as membrane-bound and secretory forms in the clinical isolates. Thus, C. tropicalis appears to be a master of immune evasion by using Pra1 protein. Further investigation using in-vivo models will help ascertain if these proteins can be novel therapeutic targets.

Abstract
Peritoneal dialysis (PD) patients have higher hospitalisation rates than the general population. The hospitalisations are not always related to dialysis issues, and physicians with little or no experience with PD may be responsible for the care of these hospitalised patients. Furthermore, the hospital may not be familiar with or equipped to manage these patients. This review highlights barriers, knowledge gaps and management strategies to guide the care of hospitalised PD patients.

Abstract
Fungal peritonitis secondary to non-albicans Candida is reported less frequently. There are uncertainties regarding the treatment of non-albicans Candida infection (i.e., preferred route or initial drug). The objective of this study is to determine the clinical characteristics and treatment used in cases of peritoneal dialysis associated fungal peritonitis secondary to non-albicans Candida. We report four cases with different clinical characteristics and different routes of administration of the antifungal drug, with no deaths. In all four patients, there were risk factors similar to those reported worldwide, without presenting the route of administration of the antifungal drug as a risk factor, suggesting that the mainstay of treatment is early initiation of the antifungal drug and early removal of the catheter.

Abstract
Background Trichoderma spp. are filamentous fungi causing invasive fungal diseases in patients with haematological malignancies and in peritoneal dialysis patients. Objectives To analyse clinical presentation, predisposing factors, treatment and outcome of Trichoderma infections. Methods A systematic literature review was conducted for published cases of invasive Trichoderma infection in PubMed until December 2021 and by reviewing the included studies’ references. Cases from the FungiScope® registry were added to a combined analysis. Results We identified 50 invasive infections due to Trichoderma species, including 11 in the FungiScope® registry. The main underlying conditions were haematological malignancies in 19 and continuous ambulatory peritoneal dialysis (CAPD) in 10 cases. The most prevalent infection sites were lung (42%) and peritoneum (22%). Systemic antifungal therapy was administered in 42 cases (84%), mostly amphotericin B (n = 27, lipid-based formulation 13/27) and voriconazole in 15 cases (30%). Surgical interventions were performed in 13 cases (26%). Overall mortality was 48% (n = 24) and highest for allogeneic HSCT and solid organ transplantation (SOT) recipients [80% (4/5) and 77% (7/9), respectively]. In patients treated with amphotericin B, voriconazole and caspofungin, mortality was 55% (15/27), 46% (7/15) and 28% (2/7), respectively. Three out of four patients treated with a combination therapy of voriconazole and caspofungin survived. Conclusions Despite treatment with antifungal therapies and surgery, invasive Trichoderma infections are life-threatening complications in immunocompromised patients, especially after HSCT and SOT. In addition, Trichoderma spp. mainly affect the lungs in patients with haematological malignancies and the peritoneum in CAPD patients.

Abstract
Introduction We sought to evaluate the predictors and outcomes of mold peritonitis in patients with peritoneal dialysis (PD). Methods This cohort study included PD patients from the MycoPDICS database who had fungal peritonitis between July 2015-June 2020. Patient outcomes were analyzed by Kaplan Meier curves and the Log-rank test. Multivariable Cox proportional hazards model regression was used to estimating associations between fungal types and patients’ outcomes. Results The study included 304 fungal peritonitis episodes (yeasts n = 129, hyaline molds n = 122, non-hyaline molds n = 44, and mixed fungi n = 9) in 303 patients. Fungal infections were common during the wet season (p <0.001). Mold peritonitis was significantly more frequent in patients with higher hemoglobin levels, presentations with catheter problems, and positive galactomannan (a fungal cell wall component) tests. Patient survival rates were lowest for non-hyaline mold peritonitis. A higher hazard of death was significantly associated with leaving the catheter in-situ (adjusted hazard ratio [HR] = 6.15, 95%confidence interval [CI]: 2.86–13.23) or delaying catheter removal after the diagnosis of fungal peritonitis (HR = 1.56, 95%CI: 1.00–2.44), as well as not receiving antifungal treatment (HR = 2.23, 95%CI: 1.25–4.01) or receiving it for less than 2 weeks (HR = 2.13, 95%CI: 1.33–3.43). Each additional day of antifungal therapy beyond the minimum 14-day duration was associated with a 2% lower risk of death (HR = 0.98, 95%CI: 0.95–0.999). Conclusion Non-hyaline-mold peritonitis had worse survival. Longer duration and higher daily dosage of antifungal treatment were associated with better survival. Deviations from the 2016 ISPD Peritonitis Guideline recommendations concerning treatment duration and catheter removal timing were independently associated with higher mortality.

Evaluation of the anti-inflammatory, antipyretic and antinociceptive activities of the hydroalcoholic extract of Rhynchospora nervosa (Vahl) Boeckeler (Cyperaceae). JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114811. [PMID: 34763042 DOI: 10.1016/j.jep.2021.114811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 10/28/2021] [Accepted: 11/03/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhynchospora nervosa (Vahl) Boeckeler (Cyperaceae), popularly known as "capim-estrela", is a native species widely distributed in Brazil. The whole plant has been used in local traditional medicine in the form of teas or syrups to treat inflammation, flu, nasal congestion, fever, swelling, and venereal disease. This is the first study to investigate the pharmacological properties of this species. AIM OF THE STUDY The present study aimed to evaluate the in vivo anti-inflammatory, antipyretic and antinociceptive potential of the lyophilized hydroalcoholic extract of R. nervosa in heterogenic Swiss mice. In addition to pharmacological studies, the total phenol and flavonoid contents of the extract were determined. MATERIAL AND METHODS The anti-inflammatory effect was evaluated through carrageenan-induced paw edema and peritonitis models. For the antinociceptive assay, the number of acetic acid-induced writhing responses in the animals was counted. Antipyretic activity was tested by yeast-induced pyrexia in mice and evaluated for 4 h. Nitric oxide (NO) concentration and leukocyte migration in the peritoneal fluid were quantified. The acute toxicity of the extract was also calculated. Quantitative analyses of total phenols and flavonoids in the extract were performed by spectrophotometric methods. RESULTS In short, the lyophilized hydroalcoholic extract of R. nervosa showed low acute toxicity in the preclinical tests (LD50 = 3807 mg/kg). A significant anti-inflammatory effect was observed, with an average reduction of carrageenan-induced paw edema of 96.37%. Comparatively, indomethacin inhibited the development of the carrageenin paw edema by 97.52%. In the peritonitis test, a significant reduction in NO levels was recorded. A reduction in the number of white cells, notably monocytes, was also observed, confirming the anti-inflammatory effect. Writhing was reduced by 86.53%, which indicates antinociceptive activity. As for antipyretic activity, no positive effects of the extract were observed. The lyophilized hydroalcoholic extract of R. nervosa presented a high content of phenolic compounds (322.47 μg GAE/mg) and total flavonoids (440.50 μg QE/mg). CONCLUSION The lyophilized hydroalcoholic extract of R. nervosa showed significant in vivo anti-inflammatory and antinociceptive activity in mice. These preliminary findings support the indication of the use of this species in folk medicine in Brazil for the treatment of inflammation.

Abstract
Peritoneal dialysis-related peritonitis remains the major complication and primary challenge to the long-term success of peritoneal dialysis (PD). The study aimed to analyze the peritonitis rate, the cause, the outcomes, and the association of peritonitis with the survival of patients on peritoneal dialysis. Patient data were collected retrospectively from medical charts. A total of 96 patients received peritoneal dialysis in the PD center from 1 January 1999 to 31 December 2018. Episodes of peritonitis (n=159) were registered in 54 (56.3%) patients. The study population was divided into two groups, a group of patients (n=54) who experienced peritonitis and a group of patients free of peritonitis (n=42). The peritonitis rate was 0.47 episodes per patient year. The majority of causative microorganisms were gram-positive bacteria (53.5%). Outcomes of the episodes of peritonitis were resolved infection in 84.9% of episodes, catheter removal in 11.3% of episodes, and death in 3.8% of the episodes of peritonitis. A Kaplan-Meier analysis and log-rank test revealed that the group with peritonitis tended to survive significantly longer than the peritonitis-free group. A 67% reduction rate in the risk of patient mortality was observed for the peritonitis group compared with the peritonitis-free group (hazard ratio: 0.33, 95% CI 0.19-0.57, P=0.000). The prevention and management of PD-related infections, resulted in their worldwide reduction, supporting the use of PD as a first-line dialysis modality.

Characteristics Analysis, Clinical Outcome and Risk Factors for Fungal Peritonitis in Peritoneal Dialysis Patients: A 10-Year Case-Control Study. Front Med (Lausanne) 2021; 8:774946. [PMID: 34926517 PMCID: PMC8671457 DOI: 10.3389/fmed.2021.774946] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 11/10/2021] [Indexed: 12/01/2022] Open
Abstract
Background: Fungal peritonitis (FP) is a rare but severe complication that can appear in patients receiving peritoneal dialysis (PD). This study aimed to investigate the incidence rate and clinical characteristics of FP, evaluate clinical outcomes between FP and bacterial peritonitis (BP) patients on PD, and especially estimate the risk factors for FP outbreak. Methods: All episodes of FP diagnosed in our hospital from January 1, 2011, to December 31, 2020, were reviewed in this single-center study. FP cases were analyzed and compared with patients diagnosed with BP in a 1:6 ratio matching for case-control study. Patient information, including clinical information, biochemical analysis, and outcomes, was recorded. Univariate and multivariate logistic regression model were used to analyze the risk factors for FP. Results: A total of 15 FP episodes were observed in 15 PD patients, with an FP rate of 0.0071 episodes per patient-year. Seventeen strains of fungi were isolated and identified. Candida was the most common pathogen (15 strains, 88.2%), followed by Aspergillus fumigatus (2 strains, 11.8%). Between the groups, FP group showed a higher rate of HD transfer and catheter removal, and a lower rate of PD resumption in the short-term outcome (all P < 0.01), while no significant difference in the mortality was noted during the whole study period. The multivariate logistic regression analysis showed that longer PD duration (odds ratio [OR] 1.042, 95% confidence interval [CI] 1.012–1.073, P < 0.01), higher serum potassium (OR 3.373, 95% CI 1.068–10.649, P < 0.05), elevated estimated glomerular filtration rate (eGFR) (OR 1.845, 95% CI 1.151–2.955, P < 0.05), reduced serum albumin level (OR 0.820, 95% CI 0.695–0.968, P < 0.05) and peritoneal effluent polymorphonuclear (PMN) count (OR 0.940, 95%CI 0.900–0.981, P < 0.01) were significantly increased the risk for FP. Conclusion: These results suggested that FP leads to higher rate of catheter removal and HD transfer, and a lower rate of PD resumption than BP, and that additional attention should be paid to hypoalbuminemia, increased serum potassium, long PD duration, and low peritoneal effluent PMN in PD patients.

Abstract
Candida parapsilosis can cause invasive fungal infection which is associated with significant morbidity and mortality. Timely management of this uncommon Candida pathogen is essential to prevent peritoneal dialysis patients from succumbing to the infectious complications of peritonitis related to it. We present a 75-year-old Caucasian female with end-stage renal disease, on peritoneal dialysis at home, who presented with peritonitis features found to be related to this rare Candida species. She was treated with four weeks course of oral fluconazole and was switched to incenter hemodialysis. Physicians need to be aware of this notorious Candida species in peritoneal dialysis patients and prompt management is essential in successful patient outcomes.

Abstract
Introduction: Bacterial peritonitis is an infection with high mortality if not treated immediately. In the absence of an intraabdominal source of infection, bacterial peritonitis may arise in patients with liver cirrhosis, in patients on peritoneal dialysis (PD) for end-stage renal disease or in patients with tuberculosis. In patients with cirrhosis, bacterial peritonitis may trigger acute on chronic liver failure with substantial mortality despite optimal treatment. In patients on PD, peritonitis may make continuation of PD impossible, necessitating the switch to hemodialysis.Areas covered: Recovery from peritonitis and prevention of complications depend on timely pharmacological management. Challenges are the broad microbiological spectrum with growing rates of antimicrobial resistance, the underlying chronic liver or kidney failure and high rates of relapse. The authors provide a review of predisposing conditions, diagnosis, and prevention of bacterial peritonitis with a particular focus on the pharmacological management.Expert opinion: Diagnosis of the type of bacterial peritonitis is essential to pharmacological management. In patients with spontaneous bacterial peritonitis, broad-spectrum antibiotics should be given intravenously in conjunction with albumin. In patients on PD, antibiotic therapy should be preferably applied intraperitoneally with empirical coverage of gram-positive and gram-negative bacteria. Secondary peritonitis usually requires surgical or interventional treatment.

Abstract
This is the first human infection caused by Hyphopichia burtonii, resulting in peritonitis in a patient on peritoneal dialysis initially diagnosed as sterile peritonitis, resulting in delayed diagnosis and treatment. This pathogen posed a challenging diagnosis, causing low-grade peritonitis and difficulty to culture with standard bacterial broth. Moreover, automated platforms for pathogenic yeast identification could not specify the species, but broad-range PCR targeting rDNA followed by DNA sequencing successfully solved the etiology.

Abstract
Objectives To provide a basis for clinical management decisions in Paecilomyces variotii infection. Methods Unpublished cases of invasive P. variotii infection from the FungiScope® registry and all cases reported in the literature were analysed. Results We identified 59 cases with P. variotii infection. Main baseline factors were presence of indwelling devices in 29 cases (49.2%), particularly peritoneal catheters (33.9%) and prosthetic heart valves (10.2%), haematological or oncological diseases in 19 (32.2%), major surgery in 11 (18.6%), and diabetes mellitus in 10 cases (16.9%). The most prevalent infection sites were peritoneum (n = 20, 33.3%) and lungs (n = 16, 27.1%). Pain and fever were frequent (n = 35, 59.3% and n = 33, 55.9%, respectively). Diagnosis was established by culture in 58 cases (98.3%). P. variotii caused breakthrough infection in 8 patients. Systemic antifungals were given in 52 patients (88.1%). Amphotericin B was administered in 39, itraconazole in 15, and posaconazole in 8 patients. Clinical isolates were frequently resistant to voriconazole, whereas the above-mentioned antifungals showed good in vitro activity. Infections of the blood and CNS caused high mortality. Overall mortality was 28.8% and death was attributed to P. variotii in 10 cases. Conclusions P. variotii causes life-threatening infections, especially in immunocompromised and critically ill patients with indwelling devices. Patients undergoing peritoneal dialysis are at particular risk. Multidisciplinary management is paramount, including molecular techniques for diagnosis and treatment with efficacious systemic antifungals. Amphotericin B, itraconazole and posaconazole are regarded as treatments of choice. Combination with flucytosine may be considered. Surgical debridement and removal of indwelling devices facilitate favourable outcome.

Abstract
BACKGROUND Fungal peritonitis (FP) is an infrequent but serious complication in children undergoing peritoneal dialysis (PD). This study aimed to explore the risk factors, clinical manifestations, causative organisms, fungal susceptibility findings, and outcomes of FP in children from Saudi Arabia. METHODS In this case-control study, the medical records and laboratory results of paediatric patients aged 0-14 years who underwent PD were reviewed for FP episodes. All FP episodes were matched with PD-related bacterial peritonitis episodes (1:4 ratio). RESULTS A total of 194 episodes of PD-related peritonitis occurred between 2007 and 2017, among which 11 were FP episodes (5.6%), representing a rate of 0.03 episodes per patient-year. Of these 11 episodes, 9 were caused by Candida species (82%). Compared with the bacterial peritonitis group, the FP group had a higher proportion of patients with congenital/infantile nephrotic syndrome (p = 0.005) and those younger than 5 years of age (p = 0.001). We observed a higher rate of catheter removal in the FP group than in the bacterial peritonitis group (p < 0.001); however, 1 patient died despite catheter removal. Moreover, 75% of Candida species isolates were susceptible to fluconazole. CONCLUSIONS This study revealed that FP is associated with a significant risk of peritoneal membrane failure among children undergoing PD. Therefore, early diagnosis and prompt management are essential. We also found that congenital/infantile nephrotic syndrome and young age (5 years old or younger) were risk factors for FP in children undergoing PD.

Abstract
Fungal peritonitis in patients undergoing peritoneal dialysis (PD) is very difficult to treat and is associated with significant morbidity and mortality. Among fungal pathogens, Aspergillus peritonitis presents a higher mortality rate when compared to Candida peritonitis and its identification as well as appropriate treatment remains a challenge for the physicians. We critical reviewed all published cases in literature of Aspergillus peritonitis in PD patients. The results showed that a total of 55 cases (51% males) of Aspergillus peritonitis in PD patients were reported from 1968 to 2019. Mean patient age was 49.54±19.63years and mean PD duration prior to fungal infection was 33.31±32.45months. Aspergillus fumigatus was isolated in 17/55 patients, Aspergillus niger in 15, Aspergillus terreus in 9, unidentified Aspergillus spp. in 6, Aspergillus flavus in 4, whereas sporadic cases of other Aspergillus spp. were reported. As far as predisposing factors are concerned, 75% of patients suffered from prior bacterial peritonitis receiving antimicrobial therapy. Initial antifungal treatment was intravenous and/or intraperitoneal administration of amphotericin B formulations monotherapy in 47.2% of patients or in combination with fluconazole in 13.2%, or with itraconazole in 13.2%, or with caspofungin in 3.8%, or with ketoconazole or with 5-FC in 1.9%, each. Peritoneal catheter removal was performed in 85.5% of cases. Mortality rate was 38.2%, while 81.8% of the survived patients switched to hemodialysis. Conclusively, Aspergillus peritonitis diagnosis can be difficult, due to unspecific symptoms. Early treatment with appropriate antifungal agents can be determinant for patient prognosis. Despite appropriate treatment, reported mortality remains high.

Abstract
BackgroundFungal peritonitis (FP) is associated with significant mortality and high risk of peritoneal failure. The optimum treatment for peritoneal dialysis (PD)-associated FP remains unclear. Since January 2000 we have been treating FP with a combination of intravenous amphotericin B and oral flucytosine, together with deferred catheter replacement. We examined the clinical course and outcome of the FP patients treated with this approach (study group). An outcome comparison was also made to an alternatively treated historic cohort (control group).MethodsThis was a single-center retrospective study. The clinical course and outcome of 13 consecutive episodes of FP occurring in 13 patients treated between January 2000 and April 2005 with the study approach were examined. The patients were treated with an incremental dose of intravenous amphotericin B to a target dose of 0.75 – 1 mg/kg body weight/day, and oral flucytosine 1 g/day upon a diagnosis of FP at 3.77 ± 0.93 days from presentation. Replacement of the peritoneal catheter was intended after complete clearing of effluent, after which, antifungal chemotherapy was continued for another 1 – 2 weeks. Their outcome was compared with 14 historic controls that were treated between April 1995 and December 1999.ResultsMean age of the study group was 58.7 ± 13.2 years; male-to-female ratio was 2:11; 6 (46.1%) were diabetic. All FP were caused by Candida species ( C. albicans, 2; C. parapsilosis, 8; C. glabrata, 3). Two (15.4%) patients died before resolution of the peritonitis. The dialysate effluent cleared in 11 patients (84.6%) after 13.2 ± 3.3 days of treatment, but 2 patients died of acute myocardial infarction before catheter replacement. Nine patients had their catheters replaced at day 26.7 ± 7.7 of treatment; all 9 returned to PD after a total of 31 ± 12.2 days of antifungal chemotherapy. Reversible liver dysfunction was common with this regimen. When compared with the 14 cases in the historic control group ( Candida species, 13; Trichosporon, 1), who were treated with amphotericin B, fluconazole, or a combination of the two, and the majority (78.6%) of whose catheters were removed before day 10 of presentation, the study group appeared to have a lower technique failure rate (30.8% vs 78.6%, p = 0.013) and similar all-cause mortality (30.7% vs 28.5%, p = NS), FP-related mortality (15.4% vs 28.5%, p = NS), and length of hospitalization (48.5 ± 30.2 vs 57.0 ± 37.7 days, p = NS). However, a significantly earlier commencement of antifungal treatment in the study group (3.8 ± 0.9 vs 5.8 ± 2.4 days, p = 0.012) could be an important confounder of outcome.ConclusionsCombination of intravenous amphotericin B and oral flucytosine with deferred catheter replacement appears to be associated with a relatively low incidence of PD technique failure, without affecting mortality in patients suffering from FP due to yeasts in this preliminary study. Nonetheless, drug-induced hepatic dysfunction was common; close monitoring during treatment is of paramount importance. The reasons accounting for the observed distinctive outcome remain unclear and further study is required to confirm the results and to investigate for the underlying mechanism.

Abstract
BackgroundPeritonitis remains the most serious complication of peritoneal dialysis (PD). Gram-positive organisms are among the most common causes of PD peritonitis; however, recent trends show increasing rates of gram-negative and fungal infections. Strategies to prevent peritonitis include the use of prophylactic topical mupirocin at the site where the PD catheter exits from the abdominal wall; however, mupirocin does not afford protection against gram-negative or fungal infections. The aim of this study is to determine if the incidence of catheter-related infections (exit-site infection, tunnel infection, or peritonitis) is significantly reduced by the routine application of Polysporin Triple antibiotic ointment (Pfizer Canada, Markham, Ontario, Canada) in comparison to mupirocin ointment.Methods and DesignThe Mupirocin Versus Polysporin Triple Study (MP3) is a multicenter, randomized, double-blinded controlled study comparing Polysporin Triple (P3) against the current standard of care. The aim of the study is to recruit 200 patients being treated with or starting on PD and randomize them to receive either mupirocin or P3 at the catheter exit site. Patients will be followed for 18 months or until death or transfer from PD to an alternate treatment modality. The primary outcome will be the time to first catheter-related infection. Catheter-related infections will be strictly defined using current guidelines and categorized into exit-site infections, infective peritonitis, or tunnel infections. The primary analysis will be an intention-to-treat analysis.DiscussionThe results of this study will help determine if the use of P3 is superior to mupirocin ointment in the prevention of catheter-related infections and will help guide evidence-based best practices.

Abstract
Objective Fungal peritonitis (FP) is a serious complication of continuous ambulatory peritoneal dialysis (CAPD), being associated with significant morbidity and mortality. The role of nystatin prophylaxis during antibiotic therapy in the prevention of FP remains controversial, especially in programs with a modest or low baseline FP rate. The aim of the present study was to evaluate the effect of nystatin prophylaxis on the occurrence of FP in programs with a relatively modest baseline FP rate. Patients and Methods Incident and prevalent patients receiving CAPD between April 1995 and April 2005 at our center were included and divided into 2 groups. The control group included 320 patients (total follow-up 8875 patient-months) being treated without nystatin before October 1999; the nystatin group included 481 patients (total follow-up 13725 patient-months) being treated after October 1999. Nystatin tablets (500000 units, 4 times per day) were given orally during whatever use of antibiotics to cover the whole course of antibiotic therapy. Occurrence of FP and antibiotic-related FP (AR-FP) in patients with and without nystatin prophylaxis was compared. Results The two groups were of similar age but the nystatin group had a significantly higher percentage of diabetics. In addition, the nystatin group had a higher proportion of patients using disconnecting twin-bag exchange systems and had a significantly lower peritonitis rate compared with the control. There were 13 and 14 episodes of FP in the nystatin and control groups respectively. The fungal peritonitis rate of the nystatin group was slightly lower than that of the control group (0.011 vs 0.019 per patient-year) but it did not reach statistical significance. There was, however, a significant decrease in the incidence and proportion of AR-FP in the nystatin group compared with the control group, which persisted even after adjustment for the peritonitis rate. Kaplan–Meier analysis further demonstrated significantly better AR-FP-free survival in the nystatin group compared with the control group. No significant side effects were observed for nystatin. Subgroup analyses in patients of the 2 different connecting systems revealed a similar but nonsignificant trend toward reduction of AR-FP in patients given nystatin prophylaxis. Conclusion Oral nystatin prophylaxis might prevent the occurrence of AR-FP in CAPD patients, resulting in a trend toward reduction in the incidence of FP even in programs with a modest baseline FP rate. A large scale, prospective, randomized controlled trial is needed to further examine this issue.

Abstract
An additional yield of culture from the removed peritoneal dialysis (PD) catheter in diagnosis of pathogen causing refractory peritonitis was assessed in 118 eligible patients from 7 PD centers. Peritoneal dialysis fluid (PDF) culture identified organisms in 86 (72.9%) patients, while the catheter culture identified organisms in 55 (46.6%) patients. PD catheter culture could additionally identify organisms in 19 patients whose PDF culture were negative, increasing the positive culture rate to 89%, in other word 16.1% reducing the culture-negative rate. PD catheter culture provided additional yield, especially in fungal and enterococcal infections.

Abstract
Backgound Fungal peritonitis (FP) is one of the most important causes of peritoneal dialysis (PD) failure, often burdened by increased morbility and mortality. This study evaluates the clinical course of FP cases that arose between 1983 and 2016 in a single PD unit. Methods We conducted a retrospective observational analysis of FP episodes recorded in the Baxter POET (Peritonitis Organism Exit sites Tunnel infections) registry and clinical records. FP incidence rate, PD and patients’ survival and clinical characteristics of the study population were analysed, taking into account the evolution of clinical practice during the study period as a result of technical innovation, scientific evidence and guideline history. Results Fourteen FP cases (2.8%) were detected. The overall incidence of PD peritonitis was one episode/27 patient-months. Candida parapsilosis was the most frequently (50%) detected yeast. Seventy-five per cent of cases were considered secondary FP. This group experienced 2.6±1.7 bacterial peritonitis before FP, most frequently due to Staphylococcus and Enterococcus species. Most patients were treated with fluconazole for ≥8 days. All subjects were hospitalized for a median time of 25 days. Tenckhoff catheter removal occurred in all cases of FP and all patients were transferred to haemodialysis. Two patients died. From December 2010 to December 2016, no FP episodes were recorded. Conclusions FP is confirmed as a significant cause of PD drop out and increases patients’ mortality risk. Prompt diagnosis of FP, targeted antifugal therapy and rapid PD catheter removal are essential strategies for improved patient and PD survival.

Abstract
The mortality associated with invasive candidiasis remains unacceptably high. The T2 magnetic resonance (T2MR) assay is a novel US FDA-approved molecular diagnostic assay for the diagnosis of candidemia that can rapidly detect the five most commonly isolated Candida spp. In clinical trials, T2MR has exhibited good clinical sensitivity and specificity. Potential benefits from the adoption of T2MR technology in the diagnostic and therapeutic algorithms for invasive candidiasis can arise from timely diagnosis of disease, increased case detection, tailored therapy and decrease in empiric antifungal treatment. As everyday clinical experience with the assay is evolving, we discuss the utility of T2MR in invasive candidiasis with and without candidemia based on the currently available evidence regarding its performance.

Abstract
The use of poorly treated water in hemodialysis centers may lead to fungal contamination, which poses a serious threat to immunologically debilitated hemodialysis patients. This study aimed to isolate and identify yeast species in the water of a Brazilian hemodialysis center by using classic microbiological techniques and Raman spectroscopy. For 12 months, a total of 288 water samples were collected from different points of the hemodialysis treatment distribution center. One hundred and forty-six yeast species were isolated and identified in the samples that tested positive for the presence of yeasts such as Candida parapsilosis (100 isolates, or 68.50%), C. guilliermondii (17 isolates, or 11.65%), Rhodotorula mucilaginosa (23 isolates, or 15.75%), R. glutinis (three isolates, or 2.05%), and Trichosporon inkin (three isolates, or 2.05%). Yeast susceptibility to the antifungal fluconazole was also assayed. Only two C. guilliermondii isolates were resistant to fluconazole: the minimal inhibitory concentrations were higher than 64 μg/mL. The different yeast species present in the water of a Brazilian hemodialysis center call for more effective water disinfection procedures in this unit. Raman spectroscopy is an excellent tool to identify yeast species and is potentially applicable in routine water monitoring in hemodialysis units.

Abstract
This paper presents data on fungal peritonitis (FP) in patients undergoing peritoneal dialysis (PD) at the University Hospital of Botucatu Medical School, São Paulo, Brazil. In a total of 422 patients, 30 developed FP, from which the medical records and the fungal isolates of 23 patient cases were studied. All patients presented abdominal pain, cloudy peritoneal effluent, needed hospitalization, had the catheter removed and were treated with fluconazole or fluconazole plus 5-flucitosine; six of them died due to FP. Concerning the agents, it was observed that Candida parapsilosis was the leading species (9/23), followed by Candida albicans (5/23), Candida orthopsilosis (4/23), Candida tropicalis (3/23), Candida guilliermondii (1/23), and Kodamaea ohmeri (1/23). All the isolates were susceptible to amphotericin B, voriconazole and caspofungin whereas C. albicans isolates were susceptible to all antifungals tested. Resistance to fluconazole was observed in three isolates of C. orthopsilosis, and dose-dependent susceptibility to this antifungal was observed in two isolates of C. parapsilosis and in the K. ohmeri isolate. Biofilm production estimates were high or moderate in most isolates, especially in C. albicans species, and low in C. parapsilosis species, with a marked variation among the isolates. This Brazilian study reinforces that FP in PD is caused by a diverse group of yeasts, most prevalently C. parapsilosis sensu stricto species. In addition, they present significant variation in susceptibility to antifungals and biofilm production, thus contributing to the complexity and severity of the clinical features.

Abstract
The exact number of patients with chronic kidney disease (CKD) in Asia Pacific is uncertain. In numeric terms, the region is home to the largest population of patients with untreated chronic kidney failure. The climatic, geographic, social, cultural, economic, and environmental diversity within this region is higher than in any other part of the world. Large parts of the region face a climate-related burden of infectious diseases. Infections contribute to the development and progression of CKD and complicate the course of patients with pre-existing CKD (especially those on dialysis therapy or who are immunosuppressed), increase the cost of CKD care, and contribute to mortality and morbidity. Kidney involvement is a feature of several infectious diseases prevalent in Asia Pacific. Examples include malaria, leptospirosis, scrub typhus, tuberculosis, hepatitis B and C virus, dengue hemorrhagic fever, and Hantaan virus infections. The contribution of infection-associated acute kidney injury to the overall burden of CKD has not been evaluated systematically. Research is needed to quantify the impact of infections on kidney health by undertaking prospective studies. Nephrologists need to work with infectious disease research groups and government infection surveillance and control programs.

Abstract
Paecilomyces variotii has previously been reported as a causative pathogen for peritonitis in patients on continuous ambulatory peritoneal dialysis and shown to be usually sensitive to amphotericin B and resistant to voriconazole. We report the first case, to our knowledge, of P. variotii peritonitis in a liver transplant patient, which was unresponsive to initial liposomal amphotericin B (L-AmB) treatment and resolved dramatically after the addition of voriconazole. The present case provides evidence for the clinical and microbiological effectiveness of voriconazole combined with L-AmB in treating P. variotii peritonitis refractory to initial L-AmB treatment.

Abstract
BACKGROUND Fungal peritonitis is a recognized complication in patients with end-stage renal failure treated with peritoneal dialysis (PD). Most infections are attributable to Candida species. In approximately one third of cases, the causative fungus is a non-Candida species. Recent reports in the literature show a rising incidence of non-candidal fungal peritonitis (NCFP). We report a case series of NCFP, together with two hitherto unreported species of fungi causing peritonitis, from a tropical geographic area (Far North Queensland). METHODS This series of 10 cases of NCFP was identified from the PD peritonitis database in Far North Queensland between 1998 and 2010. All 10 patients were from the Aboriginal and Torres Strait Islander ethnic group, 8 of whom lived in remote locations. All but 1 patient had type 2 diabetes mellitus. Of the 10 cases, 7 occurred while the patients received continuous ambulatory PD. Only 1 patient avoided catheter removal, and 5 patients were permanently transferred to hemodialysis. No patient died as a result of the fungal infection. All 10 fungi represented different species. Most (6 of 10) were saprophytic; only 2 were normal skin flora. Two of the causative species (Chaetomium and Beauveria) have rarely been associated with any form of human infection. In 7 patients, the infection occurred during the wet season (November - April). All cases met clinical criteria for peritonitis. DISCUSSION AND CONCLUSIONS The NCFP cases described in this series involved a variety of previously known fungal species and also two new species that have not been reported to cause disease in humans. Indigenous patients from Far North Queensland are particularly predisposed to infection with these exotic fungi as a result of environmental and social factors. Further understanding is desirable to help devise preventive strategies to avoid the consequences of catheter failure.

Brazilian guidelines for the management of candidiasis - a joint meeting report of three medical societies: Sociedade Brasileira de Infectologia, Sociedade Paulista de Infectologia and Sociedade Brasileira de Medicina Tropical. Braz J Infect Dis 2013; 17:283-312. [PMID: 23693017 PMCID: PMC9427385 DOI: 10.1016/j.bjid.2013.02.001] [Citation(s) in RCA: 79] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2013] [Accepted: 02/16/2013] [Indexed: 01/07/2023] Open
Abstract
Candida infections account for 80% of all fungal infections in the hospital environment, including bloodstream, urinary tract and surgical site infections. Bloodstream infections are now a major challenge for tertiary hospitals worldwide due to their high prevalence and mortality rates. The incidence of candidemia in tertiary public hospitals in Brazil is approximately 2.5 cases per 1000 hospital admissions. Due to the importance of this infection, the authors provide a review of the diversity of the genus Candida and its clinical relevance, the therapeutic options and discuss the treatment of major infections caused by Candida. Each topography is discussed with regard to epidemiological, clinical and laboratory diagnostic and therapeutic recommendations based on levels of evidence.

Abstract
BACKGROUND Fungal peritonitis (FP) is rare, but it is associated with high morbidity and mortality. PATIENTS AND METHODS A prospective study was conducted based on the peritonitis episodes registry to evaluate FP rate, possible risk factors, and outcomes. The impact of prophylactic intervention with oral fluconazole was evaluated. RESULTS Over 24 years of experience, 417 patients underwent peritoneal dialysis (PD), followed for 956 patient-years. By the end of the study, the peritonitis rate reached 0.47 episodes per patient-year of treatment (ep/pt-y). FP was detected in 24 patients. The global rate of FP was 0.03 ep/pt-y (4.8%). Candida species accounted for 92% of the FP. Risk factors identified: recent use of antibiotics in 63% (13 episodes of bacterial peritonitis and 2 exit-site infections (ESI)) and immunosuppressive therapy in 8%. While rare, the FP proportion was still observed to increase from the beginning of the program, reaching 7.8% (0.05 ep/pt-y). A strategy of antifungal prophylaxis with oral fluconazole during peritonitis or ESI antibiotic therapy was adopted, which allowed thereafter a 4.0% falling FP proportion (by study end, rate of 0.01 ep/pt-y). Catheter removal occurred in all patients. The mortality rate was 12.5%. Reinsertion of dialysis catheter was attempted in 4 patients and PD was successfully resumed in 3 patients. CONCLUSIONS FP was associated with high mortality and required early removal of the catheter in all patients. Recent use of antibiotics was a predisposing factor to PF. The quality control process determined a prophylactic strategy and reduction of PF after introduction of oral fluconazole was implemented.

Abstract
OBJECTIVE AND DESIGN The purpose of this study was to evaluate the anti-inflammatory and anti-arthritic activities of 3,4-dihydro-2,2-dimethyl-2H-naphthol[1,2-b]pyran-5,6-dione (β-lapachone; β-lap) and to elucidate its probable mode of action. METHODS Carrageenan-induced paw edema, cell migration evaluation and production of pro-inflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-6 and nitric oxide were used for this study. Freund's complete adjuvant (FCA)-induced arthritis was used as a model of chronic inflammation. β-Lap was tested in doses of 40 and 60 mg/kg, orally. RESULTS In the paw edema test, the dose of 60 mg/kg gave a higher percentage inhibition of edema (49.3 %) than control. β-Lap inhibited neutrophil migration and reduced concentrations of TNF-α, IL-6 and NO in peritoneal exudates of animals with peritonitis. In the arthritis test, β-lap inhibited edema and NO production in the serum of treated animals. CONCLUSION Significant anti-inflammatory and anti-arthritic activities were observed in animals treated with β-lap. The effects of β-lap can be attributed in part to immunomodulation with reduction of pro-inflammatory cytokines and NO.

Abstract
Background Fungal peritonitis is a serious complication of peritoneal dialysis (PD) therapy with the majority of patients ceasing PD permanently. The aims of this study were to identify risk factors and clinical associations that may discriminate between fungal from bacterial peritonitis. Methods We retrospectively identified episodes of fungal peritonitis from 2001–2010 in PD patients at Liverpool and Westmead Hospitals (Australia). Fungal peritonitis cases were matched in a 1∶2 ratio with patients with bacterial peritonitis from each institution's dialysis registry, occurring closest in time to the fungal episode. Patient demographic, clinical and outcome data were obtained from the medical records. Results Thirty-nine episodes of fungal peritonitis (rate of 0.02 episodes per patient-year of dialysis) were matched with 78 episodes of bacterial peritonitis. Candida species were the commonest pathogens (35/39; 90% episodes) with Candida albicans (37%), Candida parapsilosis (32%) and Candida glabrata (13%) the most frequently isolated species. Compared to bacterial peritonitis, fungal peritonitis patients had received PD for significantly longer (1133 vs. 775 catheter-days; p = 0.016), were more likely to have had previous episodes of bacterial peritonitis (51% vs. 10%; p = 0.01), and to have received prior antibacterial therapy (51% vs. 10%; p = 0.01). Patients with fungal peritonitis were less likely to have fever and abdominal pain on presentation, but had higher rates of PD catheter removal (79% vs. 22%; p<0.005), and permanent transfer to haemodialysis (87% vs. 24%; p<0.005). Hospital length of stay was significantly longer in patients with fungal peritonitis (26.1 days vs. 12.6 days; p = 0.017), but the all-cause 30-day mortality rate was similar in both groups. Fluconazole was a suitable empiric antifungal agent; with no Candida resistance detected. Conclusion Prompt recognition of clinical risk factors, initiation of antifungal therapy and removal of PD catheters are key considerations in optimising outcomes.

Ten-year experience with fungal peritonitis in peritoneal dialysis patients: antifungal susceptibility patterns in a North-American center. Int J Infect Dis 2011; 16:e41-3. [PMID: 22056278 DOI: 10.1016/j.ijid.2011.09.016] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2011] [Revised: 06/28/2011] [Accepted: 09/26/2011] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To describe the clinical and microbiological features associated with fungal peritonitis in peritoneal dialysis (PD) patients at Hôpital Maisonneuve-Rosemont, from August 1996 to July 2006. METHODS Cases were retrieved from the microbiology laboratory culture registry. Antifungal susceptibility was determined by the Clinical and Laboratory Standards Institute M27A3 method. RESULTS Among 288 PD patients (total follow-up of 7258 patient-months), nine were found with fungal peritonitis. Candida spp were identified in all of them, with a majority of non-albicans Candida species. Resistance to fluconazole, itraconazole, or voriconazole was as frequent as potential resistance to amphotericin B. No isolate was resistant to caspofungin and one was resistant to micafungin. Prior bacterial peritonitis was frequent (67%). All patients had their PD catheter removed and all of them survived. CONCLUSIONS In our institution, fungal peritonitis in PD patients is rare. All cases were caused by Candida species. Variable susceptibility patterns were observed, which may influence the initial empirical antifungal therapy and underscore the importance of individual speciation and susceptibility testing of invasive Candida isolates.

Anti-inflammatory and antinociceptive activities of indole-imidazolidine derivatives. Int Immunopharmacol 2011; 11:1816-22.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) represent a group of approximately 50 different medicines that are widely prescribed for the management of inflammation and that exhibit variable anti-inflammatory, anti-pyretic and analgesic activities. Most NSAIDs also exhibit a shared set of adverse effects, particularly related to gastrointestinal complications; thus, the development of new drugs for the treatment of chronic inflammation and pain continues to be an issue of high interest. Hydantoin and indole derivatives are reported to possess various pharmacological effects, including anti-inflammatory and analgesic activities. Therefore, the aim of this study was to evaluate the potential anti-inflammatory and antinociceptive activities of hybrid molecules containing imidazole and indole nuclei. The anti-inflammatory activities of 5-(1H-Indol-3-yl-methylene)-2-thioxo-imidazolidin-4-one (LPSF/NN-56) and 3-(4-Bromo-benzyl)-5-(1H-indol-3-yl-methylene)-2thioxo-imidazolidin-4-one (LPSF/NN-52) were evaluated using air pouch and carrageenan-induced peritonitis models as well as an acetic acid-induced vascular permeability model followed by IL-1β and TNF-α quantification. To evaluate the antinociceptive activities of the compounds, acetic acid-induced nociception, formalin and hot plate tests were also performed. The anti-inflammatory activities of the compounds were evidenced by a reduction in both leukocyte migration and the release of TNF-α and IL-1β in air pouch and peritonitis models. Upon acetic acid-induced nociception, a decrease in the level of abdominal writhing in the groups treated with LPSF/NN-52 (52.1%) or LPSF/NN-56 (63.1%) was observed. However, in the hot plate test, none of the derivatives tested exhibited an inhibition of nociception. These results indicate that the compounds tested exhibited promising anti-inflammatory and antinociceptive activities that likely involved the modulation of the immune system.

Abstract
A 62-year-old man on continuous ambulatory peritoneal dialysis was transferred to our hospital with recurrent abdominal pain and a cloudy peritoneal effluent. Three weeks before the transfer, his symptoms were successfully treated with broad-spectrum antibiotics. However, their effectiveness was lost for his recurrent symptoms. Fungal peritonitis was diagnosed because of an increased white blood cell count in the peritoneal fluid on admission and isolation of Candida albicans from a peritoneal fluid culture. Intravenous fos-fluconazole was immediately started, although it was ineffective for his deteriorating symptoms. The concomitant isolation of Candida albicans in a stool culture suggested that fungal peritonitis had an enteric origin. An emergency laparotomy revealed multiple diverticulosis and sigmoid colon diverticulitis. A surgical drainage was performed in addition to peritoneal catheter removal. Postoperatively, the patient's symptoms improved rapidly and there were no signs of recurrence with continuous administration of fos-fluconazole. Surgical drainage accelerated the recovery from fungal peritonitis. This patient is the first case showing the usefulness of stool culture in the diagnosis of fungal peritonitis secondary to prior bacterial peritonitis. This case also demonstrated the importance of laparotomy to confirm the enteric origin of the fungus, and the efficacy of early surgical drainage for the treatment.

Abstract
BACKGROUND AND OBJECTIVES Fungal peritonitis increases the risk of transfer to haemodialysis and mortality. METHODS We audited the effect of co-prescription of daily oral fluconazole with antibiotics in the Pan Thames centres on fungal peritonitis. RESULTS We found 49 (1.5%) fungal peritonitis cases in 3,322 episodes of peritonitis. Two centres co-prescribed prophylactic fluconazole with antibiotics, with a fungal peritonitis rate of 0.0032/patient year, compared to 0.0099 from centres not using prophylaxis. However, centres using fungal prophylaxis had lower peritonitis rates of 0.036, compared to 0.05 for the other centres. Correcting for background peritonitis rates, there was no significant difference in the incidence of fungal peritonitis. CONCLUSIONS In centres with a low incidence of fungal peritonitis, additional co-prescription of fluconazole with antibiotics appeared to reduce the risk of fungal peritonitis. However, variation in practice between centres is the main determinant of the observed incidence of fungal peritonitis rather than the use of antifungal prophylaxis.
