Design of an epitope-based peptide vaccine against Cryptococcus neoformans. FEBS Open Bio 2024. [PMID: 39020466 DOI: 10.1002/2211-5463.13858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 04/11/2024] [Accepted: 06/21/2024] [Indexed: 07/19/2024] Open
Abstract
Cryptococcus neoformans is the highest-ranked fungal pathogen in the Fungal Priority Pathogens List (FPPL) released by the World Health Organization (WHO). In this study, through in silico simulations, a multi-epitope vaccine against Cryptococcus neoformans was developed using the mannoprotein antigen (MP88) as a vaccine candidate. Following the retrieval of the MP88 protein sequences, these were used to predict antigenic B-cell and T-cell epitopes via the bepipred tool and the artificial neural network, respectively. Conserved B-cell epitopes AYSTPA, AYSTPAS, PASSNCK, and DSAYPP were identified as the most promising B-cell epitopes. While YMAADQFCL, VSYEEWMNY, and FQQRYTGTF were identified as the best candidates for CD8+ T-cell epitopes; and YARLLSLNA, ISYGTAMAV, and INQTSYARL were identified as the most promising CD4+ T-cell epitopes. The vaccine construct was modeled along with adjuvant and peptide linkers and the expasy protparam tool was used to predict the physiochemical properties. According to this, the construct vaccine was predicted to be antigenic, nontoxic, nonallergenic, soluble, stable, hydrophilic, and thermostable. Furthermore, the three-dimensional structure was also used in docking analyses with Toll-like receptor (TLR4). Finally, the cDNA of vaccine was successfully cloned into the E. coli pET-28a (+) expression vector. The results presented here could contribute towards the design of an effective vaccine against Cryptococcus neoformans.

Management of disseminated histoplasmosis in a high-complexity clinic in Cali, Colombia. Med Mycol 2024; 62:myae058. [PMID: 38806236 DOI: 10.1093/mmy/myae058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 05/14/2024] [Accepted: 05/27/2024] [Indexed: 05/30/2024] Open
Abstract
Histoplasmosis presents a substantial clinical challenge globally, with a particular prevalence in South America, especially among patients with concurrent Human Immunodeficiency Virus (HIV) infection. Despite itraconazole's established efficacy, investigating alternative therapeutic approaches remains imperative. This is the largest study in our region to date, assessing the effectiveness of the less explored posaconazole treatment. This observational study, conducted at Fundación Valle del Lili (FVL) from 2016 to 2022, encompassed adults with disseminated histoplasmosis. Patients (n = 31) were treated with liposomal amphotericin B as an initial treatment, followed by consolidation treatment with posaconazole or itraconazole. Patients with single-organ cases, those lacking microbiological diagnosis, those who received initial treatment with antifungals other than liposomal Amphotericin B and those with < 6 months follow-up were excluded (Figure 1). Analyses considered population characteristics, treatments, and outcomes. Patients (average age: 45.6; 58.1% female) had common comorbidities (HIV 38.7%, solid organ transplantation 29% and oncologic disease 12.9%). Lungs (48.4%) and lymph nodes (16.1%) were commonly affected. Biopsy (64.5%) was the primary diagnostic method. Initial treatment with liposomal amphotericin B (100%) was given for 14 days on average. Follow-up indicated 71% completion with 19.4% requiring treatment modifications. Notably, 70.9% completed a posaconazole consolidation regimen over 350 days on average. Drug interactions during consolidation (80.6%) were common. No relapses occurred, and three deaths unrelated to histoplasmosis were reported. Traditionally, itraconazole has been the prevalent initial treatment; however, in our cohort, 55.9% of patients received posaconazole as the primary option. Encouragingly, posaconazole showed favorable tolerance and infection resolution, suggesting its potential as an effective and well-tolerated alternative for consolidation treatment. This finding prompts further exploration of posaconazole, potentially leading to more effective patient care and better outcomes.

Abstract
Myriad associations between the microbiome and various facets of liver physiology and pathology have been described in the literature. Building on descriptive and correlative sequencing studies, metagenomic studies are expanding our collective understanding of the functional and mechanistic role of the microbiome as mediators of the gut-liver axis. Based on these mechanisms, the functional activity of the microbiome represents an attractive, tractable, and precision medicine therapeutic target in several liver diseases. Indeed, several therapeutics have been used in liver disease even before their description as a microbiome-dependent approach. To bring successful microbiome-targeted and microbiome-inspired therapies to the clinic, a comprehensive appreciation of the different approaches to influence, collaborate with, or engineer the gut microbiome to coopt a disease-relevant function of interest in the right patient is key. Herein, we describe the various levels at which the microbiome can be targeted-from prebiotics, probiotics, synbiotics, and antibiotics to microbiome reconstitution and precision microbiome engineering. Assimilating data from preclinical animal models, human studies as well as clinical trials, we describe the potential for and rationale behind studying such therapies across several liver diseases, including metabolic dysfunction-associated steatotic liver disease, alcohol-associated liver disease, cirrhosis, HE as well as liver cancer. Lastly, we discuss lessons learned from previous attempts at developing such therapies, the regulatory framework that needs to be navigated, and the challenges that remain.

Abstract
The misuse and overuse of classic antifungals have accelerated the development of resistance mechanisms, diminishing the efficacy of established therapeutic pathways and necessitating a shift towards alternative targets. Despite this pressing need for new treatments, the antifungal drug pipeline has been largely stagnant for the past three decades, primarily due to the high risks and costs associated with antifungal drug development, compounded by uncertain market returns. Extensive research durations, special patient populations and rigorous regulatory demands pose significant barriers to bringing novel antifungal agents to market. In response, the "push-pull" incentive model has emerged as a vital strategy to invigorate the pipeline and encourage innovation. This editorial critically examines the current clinical landscape and spotlights emerging antifungal agents, such as Fosmanogepix, Ibrexafungerp, and Olorofim, while also unraveling the multifaceted challenges faced in new antifungal drug development. The generation of novel antifungals offers a beacon of hope in the battle against antimicrobial resistance, but it is premature to declare them as definitive solutions. Their future role hinges on thorough clinical validation, cost-effectiveness assessments, and continuous post-marketing surveillance. Only through strategic implementation and integration with market strategies we can transform the landscape of antifungal development, addressing both the resistance crisis and the treatment challenges.

Abstract
End-stage liver disease (ESLD) is a life-threatening clinical syndrome and when complicated with infection the mortality is markedly increased. In patients with ESLD, bacterial or fungal infection can induce or aggravate the occurrence or progression of liver decompensation. Consequently, infections are among the most common complications of disease deterioration. There is an overwhelming need for standardized protocols for early diagnosis and appropriate management for patients with ESLD complicated by infections. Asia Pacific region has the largest number of ESLD patients, due to hepatitis B and the growing population of alcohol and NAFLD. Concomitant infections not only add to organ failure and high mortality but also to financial and healthcare burdens. This consensus document assembled up-to-date knowledge and experience from colleagues across the Asia-Pacific region, providing data on the principles as well as evidence-based current working protocols and practices for the diagnosis and treatment of patients with ESLD complicated by infections.

Abstract
BACKGROUND AND PURPOSE The need for dose adjustment of caspofungin in patients with hepatic impairment is controversial, especially for those with Child-Pugh B or C cirrhosis. The purpose of this study was to investigate the safety and efficacy of standard-dose caspofungin administration in Child-Pugh B and C cirrhotic patients in a real-world clinical setting. PATIENTS AND METHODS The electronic medical records of 258 cirrhotic patients, including 67 Child-Pugh B patients and 191 Child-Pugh C patients, who were treated with standard-dose of caspofungin at the Second Affiliated Hospital of Chongqing Medical University, China, from March 2018 to June 2023 were reviewed retrospectively. The white blood cells (WBC), hepatic, renal and coagulation function results before administration and post administration on days 7, 14 and 21 were collected, and the efficacy was assessed in all patients at the end of caspofungin therapy. RESULTS Favorable responses were achieved in 137 (53.1%) patients while 34 (13.2%) patients died. We observed that some patients experienced an increase of prothrombin time (PT) or international normalized ratio (INR), or a decrease of WBC, but no exacerbation of hepatic or renal dysfunction were identified and no patient required dose interruption or adjustment because of an adverse drug reaction during treatment with caspofungin. CONCLUSIONS Standard-dose of caspofungin can be safely and effectively used in patients with Child-Pugh B or C cirrhosis, and we appealed to re-assess the most suitable dosing regimen in this population to avoid a potential subtherapeutic exposure.

Abstract
Candidemia is a significant cause of mortality among hospitalized patients, both worldwide and in Brazil. Prompt and appropriate treatment are essential to mitigate mortality, and clinical practice guidelines aim to optimize patient care based on the best scientific evidence. This study aims to examine the management of candidemia, assessing adherence to the guidelines of the Brazilian Society of Infectious Diseases in a single center located at São Paulo, Brazil. All adult patients hospitalized from 2016 to 2018 who presented one positive blood culture for Candida spp. were included. Electronic medical records were retrospectively reviewed to collect information relevant to the treatment for candidemia, in order to assess the adherence to the Brazilian guideline for the management of candidemia in relation to nine defined outcomes, and we correlated those findings with 30-day mortality by using uni- and multivariate analyses. A total of 115 patients were included; 68 patients (59.1%) were male, with a mean age of 55 years. C. albicans, C. tropicalis and C. glabrata were the most prevalent species. In total, 80 patients (69.5%) received antifungal treatment. The adherence to Brazilian guideline recommendations was determined as described in the following: initial treatment with echinocandin in 48 (60%); step-down to fluconazole in 21 (26.2%); collection of first control blood culture in 43 (58.9%); collection of second control blood culture, if the first one had been positive, in 14 (73.6%); treatment for 14 days after the first negative blood culture in 53 (65.4%); central venous catheter (CVC) removal in 66 (82.5%); CVC removal if the first control blood culture had been positive in 17 (89.4%); performance of a transthoracic echocardiogram in 51 (63.7%) and performance of a fundoscopy in 59 (73.7%). Univariate analysis showed that CVC removal and initial echinocandin therapy were more prevalent in the surviving group, but with no statistically significant difference. On the other hand, step-down to fluconazole demonstrated higher survival rate in the multivariate analysis OR 0.15 (95% CI 0.03-0.8); p = 0.02. The analysis of these nine recommendations demonstrates that it is necessary to improve adherence to specific recommendations and also disseminate strategies of the initial use of echinocandin as the drug of choice and addressing length of treatment and follow-up and complementary exams. Our study provides reassurance that the step-down to fluconazole is safe and may be recommended, if the preexisting conditions are present.

Abstract
Nowadays, dermatophyte infections are relatively easy to cure, especially since the introduction of orally administered antifungals such as terbinafine and itraconazole. However, these drugs may cause side effects due to liver damage or their interactions with other therapeutics. Hence, the search for new effective chemotherapeutics showing antidermatophyte activity seems to be the urge of the moment. Potassium salts of N-acylhydrazinecarbodithioates are used commonly as precursors for the synthesis of biologically active compounds. Keeping that in mind, the activity of a series of five potassium N-acylhydrazinecarbodithioates (1a-e) and their aminotriazole-thione derivatives (2a-e) was evaluated against a set of pathogenic, keratinolytic fungi, such as Trichophyton ssp., Microsporum ssp. and Chrysosporium keratinophilum, but also against some Gram-positive and Gram-negative bacteria. All tested compounds were found non-toxic for L-929 and HeLa cells, with the IC30 and IC50 values assessed in the MTT assay above 128 mg/L. The compound 5-amino-3-(naphtalene-1-yl)-4,5-dihydro-1H-1,2,4-triazole-5-thione (2d) was found active against all fungal strains tested. Scanning Electron Microscopy (SEM) revealed inhibition of mycelium development of Trichophyton rubrum cultivated on nail fragments and treated with 2d 24 h after infection with fungal spores. Transmission Electron Microscopy (TEM) observation of mycelium treated with 2d showed ultrastructural changes in the morphology of germinated spores. Finally, the RNA-seq analysis indicated that a broad spectrum of genes responded to stress induced by the 2d compound. In conclusion, the results confirm the potential of N-acylhydrazinecarbodithioate derivatives for future use as promising leads for new antidermatophyte agents development.

Abstract
Acute leukemias are complex diseases to treat and have a high mortality rate. The immunosuppression caused by chemotherapy also causes the patient to become susceptible to a variety of infections, including invasive fungal infections. Protocols established in many countries attempt to prevent these infections through the use of pharmacological antifungal prophylaxis. This systematic review and meta-analysis investigates the existing evidence for the use of antifungal prophylaxis in patients undergoing induction chemotherapy for acute leukemia, and how prophylaxis can affect treatment response and mortality. Through the use of a population-variable-outcome strategy, keywords were utilized to search online databases. The included studies were selected and the data was collected to develop descriptive results for all studies, and, for studies that met the criteria, a meta-analysis of the Relative Risk (RR) was analyzed for infection rates, in-hospital mortality, and complete remission. A total of 33 studies were included in this systematic review, with most studies presenting positive results (n = 28/33) from the use of antifungal prophylaxis. Using a random effects model, the pooled results of the meta-analysis presented lower invasive fungal infections in AML (RR: 0.527 (95% CI: 0.391; 0.709). p < 0.001). p < 0.001) and ALL (RR: 0.753 (95% CI: 0.574; 0.988). p = 0.041). when antifungal prophylaxis was used. No discernible difference was encountered in the rate of complete remission when using prophylaxis. Antifungal prophylaxis provides a lower risk of invasive fungal infections and in-hospital mortality in acute leukemia patients undergoing induction chemotherapy.

The impact of gene polymorphism and hepatic insufficiency on voriconazole dose adjustment in invasive fungal infection individuals. Front Genet 2023; 14:1242711. [PMID: 37693307 PMCID: PMC10484623 DOI: 10.3389/fgene.2023.1242711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 08/10/2023] [Indexed: 09/12/2023] Open
Abstract
Voriconazole (VRZ) is a broad-spectrum antifungal medication widely used to treat invasive fungal infections (IFI). The administration dosage and blood concentration of VRZ are influenced by various factors, posing challenges for standardization and individualization of dose adjustments. On the one hand, VRZ is primarily metabolized by the liver, predominantly mediated by the cytochrome P450 (CYP) 2C19 enzyme. The genetic polymorphism of CYP2C19 significantly impacts the blood concentration of VRZ, particularly the trough concentration (Ctrough), thereby influencing the drug's efficacy and potentially causing adverse drug reactions (ADRs). Recent research has demonstrated that pharmacogenomics-based VRZ dose adjustments offer more accurate and individualized treatment strategies for individuals with hepatic insufficiency, with the possibility to enhance therapeutic outcomes and reduce ADRs. On the other hand, the security, pharmacokinetics, and dosing of VRZ in individuals with hepatic insufficiency remain unclear, making it challenging to attain optimal Ctrough in individuals with both hepatic insufficiency and IFI, resulting in suboptimal drug efficacy and severe ADRs. Therefore, when using VRZ to treat IFI, drug dosage adjustment based on individuals' genotypes and hepatic function is necessary. This review summarizes the research progress on the impact of genetic polymorphisms and hepatic insufficiency on VRZ dosage in IFI individuals, compares current international guidelines, elucidates the current application status of VRZ in individuals with hepatic insufficiency, and discusses the influence of CYP2C19, CYP3A4, CYP2C9, and ABCB1 genetic polymorphisms on VRZ dose adjustments and Ctrough at the pharmacogenomic level. Additionally, a comprehensive summary and analysis of existing studies' recommendations on VRZ dose adjustments based on CYP2C19 genetic polymorphisms and hepatic insufficiency are provided, offering a more comprehensive reference for dose selection and adjustments of VRZ in this patient population.

Abstract
Liver disease causes relative compromise of the host immune system through multiple overlapping mechanisms and is an established risk factor for invasive fungal diseases including candidiasis and cryptococcosis. This immunologic derangement also leads to rapid progression of disease with resultant increases in morbidity and mortality. We describe severe coccidioidomycosis cases in the setting of liver dysfunction. Collaborative multi-center epidemiologic studies should be performed to determine the incidence of severe coccidioidomycosis in patients with concurrent liver disease.

Abstract
Background To observe the changes of hepatic function and efficacy of conventional dosage of caspofungin in the treatment of patients with different Child–Pugh scores. Methods In total, 200 patients (Child–Pugh A group: 66 patients, Child–Pugh B group: 83 patients, Child–Pugh C group: 51 patients) treated with caspofungin from May 2018 to March 2021 in the Second Affiliated Hospital of Chongqing Medical University were enrolled. Main investigation items were as follows: sex, age, weight, duration of treatment, dosage, department, underlying diseases, risk factors for fungal infection, albumin, liver enzyme, total bilirubin, serum creatinine, estimated glomerular filtration rate. To investigate the changes of liver, kidney function tests and efficacy during the treatments of caspofungin. Patients were divided into three groups according to the duration of treatment of caspofungin:1-week group, 2-week group and 3-week group, respectively. Results In the three groups, albumin, liver enzyme levels, total bilirubin and serum creatinine, estimated glomerular filtration rate had no significant difference (P > 0.05). The efficacy of different Child–Pugh scores and different duration of treatment was also significantly different (P > 0.05). Conclusions Caspofungin is well tolerated and highly effective. And it will not exacerbate the hepatic and renal function when administered with the not-reducing dose, which indicate the clinical application value of caspofungin. Besides, extending the treatment duration has little effect on improving the efficacy of caspofungin. The drug should be withdrawn timely according to the patients’ clinical condition in order to reduce the adverse reactions and economic burden.

Abstract
Coccidioidomycosis is an infectious disease caused by Coccidioides immitis or C. posadasii fungus. Humans usually get infected by inhaling spores risen from the soil. Although in 60 percent of cases symptoms are absent, remaining patients can develop various manifestations of the disease, from flu-like symptoms to severe dissemination or meningitis. In endemic regions (California, Arizona, Mexico, Central, and South America), pulmonary coccidioidomycosis causes 25% of community-acquired cases of pneumonia. We present the first registered case of pulmonary coccidioidomycosis in Lithuania. Clinical presentation, pathogenesis, treatment options, and diagnostic alternatives are discussed.

Abstract
BACKGROUND Candida is an opportunistic fungus often present in the oral mucosa. In the compromised immune system, it may become pathogenic and cause oral candidiasis. This infection is more common with Candida albicans; though, non-albicans Candida spp also have significant relevance. Current treatment guidelines include polyenes, azoles and echinocandins, where fluconazole is the primary therapeutic option. However, both inherited and acquired resistance to fluconazole is exhaustively reported. The development of resistance has resulted in the worsening of the original and re-emergence of new fungal diseases. Thus, the development of an anti-candidiasis therapy with a satisfactory outcome is the urgent need of the hour. OBJECTIVE This review article aims to stimulate the research in establishing the synergistic efficacy of various flavonoids with fluconazole to combat the resistance and develop an effective pharmacotherapy for the treatment of oral candidiasis. Further, in this article, we discuss in detail the mechanisms of action of fluconazole, along with the molecular basis of development of resistance in Candida species. METHOD PubMed and other databases were used for literature search. RESULTS The designing of natural drugs from the plant- derived phytochemicals are the promising alternates in modern medicine. The challenge today is the development of alternative anti- oral candidiasis drugs with increased efficacy, bioavailability and better outcome which can combat azole resistance. Identifying the flavonoids with potential antifungal action at low concentrations seems to meet the challenges. CONCLUSION Phyto-active constituents, either alone or in combination with conventional antibiotics may be an effective approach to deal with global antimicrobial resistance. The efficacy of herbal therapy for decades suggests that bacteria, fungi, and viruses may have a reduced ability to adapt and resistance to these natural antimicrobial regimes.

Abstract
Parenteral sustained release drug formulations, acting as preferable platforms for long-term exposure therapy, have been wildly used in clinical practice. However, most of these delivery systems must be given by hypodermic injection. Therefore, issues including needle-phobic, needle-stick injuries and inappropriate reuse of needles would hamper the further applications of these delivery platforms. Microneedles (MNs) as a potential alternative system for hypodermic needles can benefit from minimally invasive and self-administration. Recently, polymeric microneedle-mediated sustained release systems (MN@SRS) have opened up a new way for treatment of many diseases. Here, we reviewed the recent researches in MN@SRS for transdermal delivery, and summed up its typical design strategies and applications in various diseases therapy, particularly focusing on the applications in contraception, infection, cancer, diabetes, and subcutaneous disease. An overview of the present clinical translation difficulties and future outlook of MN@SRS was also provided.

Abstract
Patients with acute and chronic liver impairment are susceptible to invasive fungal infections such as candidemia and invasive pulmonary aspergillosis as a result of cirrhosis-associated immune dysfunction, humoral immunodeficiency, cell-mediated dysfunction and systemic inflammation. Besides classical risk factors for invasive fungal infection, acute-on-chronic liver failure, corticosteroid use, gastrointestinal bleeding, and prophylactic use of antibiotics are all additional conditions which are related to the potential development of fungal infections. Therefore, high-risk patients should be carefully followed by microbiological surveillance including cultures but also by imaging and fungal biomarkers for providing early diagnosis. Echinocandins are still the mainstay and first line antifungal therapy in cases of invasive candidiasis. Due to concerns of liver toxicity and in cases of renal impairment liposomal amphotericin B is a suitable alternative to voriconazole in patients with invasive pulmonary aspergillosis. Although, data of isavucoanzole and posaconazole use in those patients are also promising more specific studies in the subgroup of patients with liver impairment are needed. Especially, due to the late diagnosis and multiple organ dysfunction usually present in patients with liver impairment morbidity and mortality rates remain high. Based on the broad spectrum of diverse reports with varying content and quality and in some cases lack of evidence we performed a systematic review on this topic.

Abstract
INTRODUCTION Aspergillus may cause different types of lung infections: invasive, chronic pulmonary or allergic bronchopulmonary aspergillosis. Pharmacological management with antifungals poses as a challenge. Patients diagnosed with pulmonary aspergillosis are complex, as well as the problems associated with antifungal agents. AREAS COVERED This article reviews the pharmacology of antifungal agents in development and currently used to treat pulmonary aspergillosis, including the mechanisms of action, pharmacokinetics, pharmacodynamics, dosing, therapeutic drug monitoring and safety. Recommendations to manage situations that arise in daily clinical practice are provided. A literature search of PubMed was conducted on November 15th, 2020 and updated on March 30th, 2021. EXPERT OPINION Recent and relevant developments in the treatment of pulmonary aspergillosis have taken place. Novel antifungals with new mechanisms of action that extend antifungal spectrum and improve pharmacokinetic-related aspects, drug-drug interactions and safety are under current study. For those antifungals already marketed, new data related to pharmacokinetics, pharmacodynamics, dose adjustments in special situations, therapeutic drug monitoring and safety are available. To maximize efficacy and reduce the risk of associated toxicities, it is essential to choose the most appropriate antifungal; optimize its dose, interval, route of administration and length of treatment; and prevent side effects.

Abstract
Background 5-fluorocytosine is a pyrimidine and a fluorinated cytosine analog mainly used as an antifungal agent. It is a precursor of 5-fluorouracil, which possesses anticancer properties. To reduce systemic toxicity of 5-fluorouracil during chemotherapy, 5- fluorocytosine can be used as a targeted anticancer agent. Expression of cytosine deaminase by a viral vector within a tumor allows targeted chemotherapy by converting 5-fluorocytosine into the cytotoxic chemotherapeutic agent 5-fluorouracil. However, little is known about the tolerance of 5-fluorocytosine in dogs after prolonged administration. Results In three healthy Beagle dogs receiving 100 mg/kg of 5-fluorocytosine twice daily for 14 days by oral route, non-compartmental pharmacokinetics revealed a terminal elimination half-life of 164.5 ± 22.5 min at day 1 and of 179.2 ± 11.5 min, after 7 days of administration. Clearance was significantly decreased between day 1 and day 7 with 0.386 ± 0.031 and 0.322 ± 0.027 ml/min/kg, respectively. Maximal plasma concentration values were below 100 µg/ml, which is considered within the therapeutic margin for human patients. 5-fluorouracil plasma concentration was below the limit of detection at all time points. The main adverse events consisted of depigmented, ulcerated, exudative, and crusty cutaneous lesions 10 to 13 days after beginning 5-fluorocytosine administration. The lesions were localized to the nasal planum, the lips, the eyelids, and the scrotum. Histological analyses were consistent with a cutaneous lupoid drug reaction. Complete healing was observed 15 to 21 days after cessation of 5-fluorocytosine. No biochemical or hematological adverse events were noticed. Conclusions Long term administration of 5-fluorocytosine was associated with cutaneous toxicity in healthy dogs. It suggests that pharmacotherapy should be adjusted to reduce the toxicity of 5-fluorocytosine in targeted chemotherapy.

Abstract
BACKGROUND Candidemia is a common opportunistic infection causing substantial morbidity and mortality. Because of an increasing proportion of non-albicans Candida species and rising antifungal drug resistance, the Infectious Diseases Society of America (IDSA) changed treatment guidelines in 2016 to recommend echinocandins over fluconazole as first-line treatment for adults with candidemia. We describe candidemia treatment practices and adherence to the updated guidelines. METHODS During 2017-2018, the Emerging Infections Program conducted active population-based candidemia surveillance at nine U.S. sites using a standardized case definition. We assessed factors associated with initial antifungal treatment for the first candidemia case among adults using multivariable logistic regression models. To identify instances of potentially inappropriate treatment, we compared the first antifungal drug received with species and antifungal susceptibility testing (AFST) results from initial blood cultures. RESULTS Among 1,835 patients who received antifungal treatment, 1,258 (68.6%) received an echinocandin and 543 (29.6%) received fluconazole as initial treatment. Cirrhosis (adjusted odds ratio = 2.06, 95% confidence interval: 1.29-3.29) was the only underlying medical condition significantly associated with initial receipt of an echinocandin (versus fluconazole). Over half (n = 304, 56.0%) of patients initially treated with fluconazole grew a non-albicans species. Among 265 patients initially treated with fluconazole and with fluconazole AFST results, 28 (10.6%) had a fluconazole-resistant isolate. CONCLUSIONS A substantial proportion of patients with candidemia were initially treated with fluconazole, resulting in potentially inappropriate treatment for those involving non-albicans or fluconazole-resistant species. Reasons for non-adherence to IDSA guidelines should be evaluated, and clinician education is needed.

Pericarditis Caused by Enterococcus faecium with Acute Liver Failure Treated by a Multifaceted Approach including Antimicrobials and Hemoadsorption. Case Rep Crit Care 2021; 2021:8824050. [PMID: 33815848 PMCID: PMC7987411 DOI: 10.1155/2021/8824050] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 02/16/2021] [Indexed: 12/12/2022] Open
Abstract
Background Sepsis and septic shock are still life-threatening diseases with a high mortality rate. We report a complex case of peritonitis with pericarditis and acute liver failure caused by septic shock. Potentially hepatotoxic antibiotic therapy levels were monitored using the liver maximum capacity (LiMAx®) test, and standard treatment was supplemented by adjunctive hemoadsorption with CytoSorb®. Case Presentation. The case features a 29-year-old woman with a history of Crohn's disease and cachexia. Peritonitis caused by Enterococcus faecium was diagnosed later due to an ileum perforation. The hematogenic spread led to pericarditis. In addition, sepsis-related acute liver failure complicated antimicrobial therapy further. The combination of standard therapy, anti-infective medication, and blood purification was associated with inflammation control, hemodynamic stabilization, and a concomitant decrease in vasopressor support. An efficient, sustained reduction in plasma bilirubin levels was achieved while maintaining liver function. Conclusions This case shows how complex infectious diseases with an atypical infectious focus resulting in septic shock can be successfully treated. A combination of antimicrobial (tigecycline and caspofungin) and long-term adjunctive hemoadsorption therapy was administered while hepatotoxic antibiotic medication was monitored by liver function testing.

Abstract
Background and Aims: Dermatophytosis has always been a common superficial mycosis in India. However, the past 6-7 years have seen an unprecedented increase in the number of patients affected by recurrent, chronic, recalcitrant and steroid modified dermatophytosis involving the glabrous skin (tinea corporis, tinea cruris and tinea faciei). Importantly, there has been a notable decrease in clinical responsiveness to commonly used antifungals given in conventional doses and durations resulting in difficult-to-treat infections. Considering that scientific data on the management of the current epidemic of dermatophytosis in India are inadequate, the Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) Task force Against Recalcitrant Tinea (ITART) has formulated a consensus statement on the management of dermatophytosis in India. Methods: Seventeen dermatologists with a focussed interest in dermatophytosis participated in a Delphi consensus method, conducted in three rounds. They responded as either “agree” or “disagree” to 132 statements prepared by the lead experts and gave their comments. Consensus was defined as an agreement of 80% or higher concurrence. Statements on which there was no consensus were modified based on the comments and were then recirculated. The results were finally analysed in a face-to-face meeting and the responses were further evaluated. A draft of the consensus was circulated among the participants and modified based on their inputs. Results: Consensus was achieved on 90 of the 132 statements. Direct microscopy using potassium hydroxide mount was recommended in case of diagnostic difficulty on clinical examination. Counselling of patients about strict adherence to general measures and compliance to treatment was strongly recommended as the key to successful management of dermatophytosis. A combination of systemic and topical antifungal drugs was recommended for the treatment of glabrous tinea in the current scenario. Topical corticosteroid use, whether used alone or in combination with other components, was strongly discouraged by all the experts. It was suggested that topical antifungals may be continued for 2 weeks beyond clinical resolution. Itraconazole and terbinafine were recommended to be used as the first line options in systemic therapy, whereas griseofulvin and fluconazole are alternatives. Terbinafine was agreed to be used as a first line systemic agent in treatment naïve and terbinafine naïve patients with glabrous tinea. Regular follow-up of patients to ensure compliance and monitoring of clinical response was recommended by the experts, both during treatment and for at least 4 weeks after apparent clinical cure. Longer duration of treatment was recommended for patients with chronic, recurrent and steroid modified dermatophytosis. Conclusion: Consensus in the management of dermatophytosis is necessary in the face of conventional regimens proving ineffective and dearth of clinical trials re-evaluating the role of available antifungals in the wake of evolving epidemiology of the infection in the country. It needs to be backed by more research to provide the required level of evidence. It is hoped that this consensus statement improves the quality of care for patients with dermatophytosis, which has emerged as a huge public health problem, imposing considerable financial burden on the country.

Abstract
Voriconazole is one of the most frequently used antifungal drugs for the initial treatment of invasive aspergillosis, but liver-related adverse events occur frequently and usually lead to drug discontinuation. Moreover, the mechanism of voriconazole-induced hepatotoxicity remains unsettled. A holistic understanding of its mechanism is critical to prevent liver-related adverse events. Metabolomics has been demonstrated to be a helpful strategy for investigating drug-induced toxicity. This study aimed to utilize human plasma samples to investigate the mechanism of voriconazole-induced hepatotoxicity through a metabolomics approach. Patients that were administered voriconazole were classified into a voriconazole-induced hepatotoxicity group and control group (n = 65, 18% hepatotoxicity). Plasma samples were analyzed by targeted metabolomics using ultra-performance liquid chromatography coupled with triple quadrupole mass spectrometry. The obtained peak areas for each metabolite were utilized for correlation analysis, fold change evaluation, and univariate statistical tests to identify metabolites associated with voriconazole-induced hepatotoxicity. This study showed a significantly lower glutamine-to-glutamate ratio (p = .04) and a higher β-N-acetylglucosamine (p = .003) in the voriconazole-induced hepatotoxicity group, implying the presence of oxidative stress. Other significant metabolites also indicated several adaptive responses to oxidative stress in patients with voriconazole-induced toxicity, including cell repair, energy production, and alteration to bile acid hemostasis. Furthermore, a metabolite panel consisting of α-ketoglutarate, glycocholate, and β-N-acetylglucosamine demonstrated better performance for detecting voriconazole-induced hepatotoxicity than conventional liver function tests. These metabolomics findings reveal that voriconazole-induced hepatotoxicity is associated with oxidative stress.

Abstract
We identified a new series of azole antifungal agents bearing a pyrrolotriazinone scaffold. These compounds exhibited a broad in vitro antifungal activity against pathogenic Candida spp. (fluconazole-susceptible and fluconazole-resistant) and were 10- to 100-fold more active than voriconazole against two Candida albicans isolates with known mechanisms of azole resistance (overexpression of efflux pumps and/or specific point substitutions in the Erg11p/CYP51 enzyme). Our lead compound 12 also displayed promising in vitro antifungal activity against some filamentous fungi such as Aspergillus fumigatus and the zygomycetes Rhizopus oryzae and Mucor circinelloides and an in vivo efficiency against two murine models of lethal systemic infections caused by Candida albicans.

Dosing of Antimycotic Treatment in Sepsis-Induced Liver Dysfunction by Functional Liver Testing with LiMAx®. Case Rep Crit Care 2019; 2019:5362514.

Abstract
Background Sepsis-treatment is one of the major challenges in our time. Especially fungal infections play an important role in patient's morbidity and mortality. In patients with septic shock, liver function is often significantly impaired and therefore also hepatic drug metabolism is altered. Case Presentation We report about a 56-year-old man suffering from invasive fungal infection with multiorgan failure, after complicated medical history due to symptomatic infrarenal aortic aneurysm. On the first postoperative day, a CT scan was undertaken due to massive back pain showing renal infarction on both sides. As qualitative and quantitative renal function was impaired, hemodialysis was started immediately. Subsequently, the patient developed a compartment syndrome of the left leg and underwent fasciotomy. On admission day 7, the patient presented with hematochezia leading to colonoscopy. During this procedure, an ischemic colitis was observed. As conservative treatment failed, the patient underwent Hartmann's procedure due to progredient ischemia followed by a worsening of the clinical status due to sepsis. The patient suffered from an invasive fungal infection with Candida spp. and Aspergillus spp. Systemic antifungal treatment was initiated. Although azoles are considered first-line treatment in these cases we chose the echinocandin caspofungin for its presumed lower impact on liver function compared to azoles like voriconazole or Amphothericin B. However, caspofungin is also metabolised in the liver and can cause hepatotoxic effects. Therefore we measured metabolic liver function capacity using LiMAx®and adapted the patient's dose of caspofungin to the evaluated liver function capacity to achieve an effective and liver-protective level of the active drug. After complicated medical history with 15 weeks of hospital stay, the patient was discharged in general good condition. Conclusions To our knowledge, this is the first report that relates antimycotic drug dosing to a functional liver test. We provide a new approach for sepsis treatment considering liver function capacity to optimize dosage of hepatically metabolised drugs with potential hepatotoxic effects.

Abstract
A 45-year-old man with alcohol-related decompensated cirrhosis presented with jaundice, fever, headache and altered sensorium. At presentation, he had tachycardia, disorientation to time and place, asterixis, icterus and upgoing plantar response. Investigations showed anaemia, thrombocytopenia, leucocytosis, hyperbilirubinemia and elevated arterial ammonia. Despite management with antihepatic coma measures and normalisation of ammonia, broad-spectrum antibiotics, 20% albumin, the patient worsened. On day 3, the patient developed generalised tonic-clonic seizure prompting mechanical ventilation. Examination showed right proptosis, chemosis and pupillary anisocoria. MRI brain showed multifocal infarcts in the right temporal lobe, right cerebellum and brainstem with inflammation in the right orbit, infratemporal fossa with right internal carotid artery thrombosis, and suspicious maxillary sinus thickening. Nasal scrapings showed aseptate fungal hyphae and serum galactomannan index was positive. Despite receiving liposomal amphotericin-B, patient had an unfavourable outcome. Intracranial invasive mycosis can mimic hepatic encephalopathy and is associated with high mortality in cirrhotics. A high index of suspicion, positive biomarkers and diagnostic radiology may provide the key to the diagnosis.

Abstract
Some patients with candidiasis seek alternatives drug to treat vaginal yeast infection like herbal preparations and probiotics. However, the effectiveness of such treatments has not received much study. In this research, the unique chitinotrophic Bacillus was isolated on shrimp shell from salt lakes and identified as Bacillus altitudinis by 16SRNA sequencing. This strain produced a novel chitin-oligosaccharide material and thermostable chitinase (5.1 units/ml) during 4 days incubation on shrimp shell medium; nevertheless, its growth on nutrient agar was negative. The zymogram showed less than 50 kD protein responsible for chitinase activities. The LC/MS detection of concentrate fermented products showed the production of oligosaccharide during chitin fermentation. As results of shrimp shell degradation, 65.6 mg/l protein, 73.4 mg/l N-acetyl glucose amine, and oligosaccharide were produced. Synergism activities of chitooligosaccharide and chitinase from this strain against fungi and pathogen candida (staining with methylene blue showed that almost 50% of 106 cells were died during 6 h) are promising for new anti-fungal drug with no side effect.
