Fungal endocarditis: what do we know in 2019?

Fungal endocarditis: what do we know in 2019? Kardiol Pol. 2019 Jun 19;: Authors: Ammannaya GKK, Sripad N Abstract Fungal endocarditis (FE) is an infrequent, but a lethal condition. Candida and Aspergillus species are the two most commonly implicated pathogenic fungi. Clinical presentation is most often that of a fever of unknown origin which is hard to differentiate from bacterial endocarditis. The diagnosis of FE is extremely challenging and now shifting towards molecular diagnostic techniques. Rapid and aggressive treatment with a combination of antifungal therapy and surgical debridement is imperative to improve outcomes. PMID: 31215523 [PubMed - as supplied by publisher]

Publication date: Available online 9 January 2020Source: IDCasesAuthor(s): Abhimanyu Aggarwal,, Karen Hogan,, Armando Paez,AbstractAspergillus endocarditis is a rare cause of culture-negative fungal endocarditis, after Candida endocarditis. Typical risk factors include intravenous drug use, immunosuppression, prior cardiac surgery or presence of prosthetic heart valves, hematopoietic stem cell or solid organ transplantation. Common presentations include signs and symptoms consistent with endocarditis but with negative bacterial blood cultures. Here, we present a case report of a 49-year-old male without known risk factors ...

This study has revealed the intestinal and hepatopancreas mycobiota of L. vannamei and the effects of diseases and seasonal variation to the mycobiota. Our study provides important guidance for Pacific white shrimp farming and sheds further insight on the fungal microbiota. Introduction The digestive system hosts a large number of microorganisms dominated by bacteria, which constitute an enormous microbial ecosystem called the microbiota (O’Hara and Shanahan, 2006; Clemente et al., 2012). The microbiota has multiple functions, such as the maintenance of the functional stability and metabolic balance in the di...

Conclusion In conclusion, F. keratoplasticum and F. petroliphilum were the most frequent species in this study. Amphotericin B showed lower MICs against Fusarium species whereas the antifungal azoles and the fungicide difenoconazole exhibited higher MICs against FSSC. Ethics Statement Samples were collected during routine patient care and the study was retrospective, therefore it was determined by the local Institutional Review Board of the Hospital de Clínicas, Federal University of Paraná and CAPES that ethical clearance was not indicated. Author Contributions PH, AA-H, FQ-T, and JM designed the study....

Conclusion: There is a change in the spectrum and antimicrobial susceptibility of organisms causing IE. We encountered several difficulties with the use of the MDC as 43.5% patients had no predisposing factors for IE and blood cultures were negative in 22.6% cases. In our study, PVE was the most common predisposing condition for IE. VGS followed by enterococci were found to be the commonest cause for IE in our setting. Both organisms show variable drug resist patterns. MRSA was isolated in 1 patient only. Thus vancomycin may not be required as empiric treatment in our setting. This is important from the perspective of anti...

We report a case of Lecythophora EE that was successfully managed with pars plana vitrectomy along with intravitreal and systemic voriconazole. Endogenous endophthalmitis (EE) is a potentially devastating intraocular infection caused by intraocular spread of pathogens through blood stream. It generally accounts for 2%–16% of all reported endophthalmitis cases.[1] Predisposing risk factors include diabetes mellitus, malignancies, intravenous drug use, organ abscess, immunosuppressive therapy, indwelling catheters, urinary tract infection, organ transplant, end-stage renal or liver disease, and endocarditis.[2]...

Candida and Aspergillus species occupy the prominent position as etiological agents of this invasive disease. Intravenous devices such as pacemakers, central line related thrombosis and prolonged use of antibiotics are major risk factors for FE. The epidemiology of endocarditis cases is also evolving over time with exceptionally rare species causing more inv...

Abstract As a part of ongoing investigation of Acokanthera oppositifolia (Lam.) Codd., four compounds were isolated from its seeds, a new compound; lup-20(29)-en-3β-O-(3'-β-hydroxy) palmitate (1), three known compounds; a triterpene; lupeol (2), a cardiac glycoside; acovenoside A (3) and a sterol; β-sitosterol (4). Their structures were investigated using 1D &2D- (1)H and (13)CNMR spectroscopy. Antimicrobial potential of the compounds was evaluated against 10 microorganisms responsible for endocarditis. The minimum inhibitory concentration (MIC) of the compounds was determined using broth microd...
