Evaluating predictors of invasive candidiasis in patients with and without candidemia on micafungin.

Evaluating predictors of invasive candidiasis in patients with and without candidemia on micafungin. Proc (Bayl Univ Med Cent). 2018 Jan;31(1):30-34 Authors: Carr A, Colley P, Berhe M, Nguyen HL Abstract Numerous risk factors have been linked to invasive candidiasis; however, they are nonspecific and often trigger empiric antifungal therapy in a large number of patients. Identification of more precise predictors could promote judicious use of empiric echinocandins. In this retrospective review, 127 patients with blood cultures positive for Candida spp. were compared to a randomly selected cohort of 134 patients on empiric micafungin for ≥3 days and with blood cultures negative for Candida spp. Factors associated with candidemia included total parenteral nutrition (TPN; 26.0% vs 15.7%, P = 0.040), multifocal Candida colonization (23.6% vs 3.0%, P

Conclusion: Cladosporium can cause endogenous endophthalmitis and mimic toxoplasma retinochoroiditis. Vitreous biopsy can help in diagnosis in the absence of positive blood culture. Intravitreal voriconazole along with systemic voriconazole shows a good response. PMID: 31825695 [PubMed - as supplied by publisher]

In this study, we determined the antimicrobial activity of ten essential oils (EOs)—oregano, thyme, clove, arborvitae, cassia, lemongrass, melaleuca, eucalyptus, lavender, and clary sage—against drug-resistant microorganisms previously isolated from patients with skin infections. The essential oil compositions were determined using gas chromatography coupled to mass spectrometry (GC/MS). The assayed bacteria included Pseudomonas aeruginosa, Proteus vulgaris, Citrobacter koseri, and Klebsiella pneumoniae. Two drug-resistant yeasts (Candida albicans and Candida parapsilosis) were also involved in our surv...

ecka Milewski The development and spread of resistance of human pathogenic bacteria to the action of commonly used antibacterial drugs is one of the key problems in modern medicine. One of the especially dangerous and easily developing antibiotic resistant bacterial species is Staphylococcus aureus. Anthra[1,2-d][1,2,3]triazine-4,7,12(3H)-triones 22–38 have been developed as novel effective antistaphylococcal agents. These compounds have been obtained by sequential conversion of 1-amino-9,10-dioxo-9,10-dihydroanthracene-2-carboxylic acid (1) and 1-amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-carboxyli...

This study was designed to examine the prevalence of Candida albicans alcohol dehydrogenase 1 (CaADH1) gene in oral dysplasia as well as oral squamous cell carcinoma (OSCC) with and without lymph node metastasis (LNM) using reverse transcription polymerase chain reaction (RT-PCR) in order to determine its role in initiation, propagation and metastasis of oral dysplasia and carcinoma. Formalin-fixed parafin-embedded specimens were grouped into four groups: 7 control, 16 oral dysplasia, 16 OSCC without LNM and 15 OSCC with LNM. All specimens were examined by periodic acid Schiff (PAS) stain to detect Candida h...

(Natural News) Lung moss (Lobaria pulmonaria) contains plant-based compounds with antibiotic and anti-fungal properties. A study from the Shandong University (SDU) tested their efficacy on drug-resistant Candida albicans to identify the most active molecules. The researchers received funding from the National Natural Science Foundation and the SDU’s Young Scholars Program. They published their findings in...

AbstractSepsis remains a leading cause of mortality worldwide and is characterized by sustained inflammatory responses, reflected as changes in the expression profile of cytokines with time. The aim of the present study was to investigate the dynamic changes in complete blood count, serum chemistry, procalcitonin (PCT), tumor necrosis factor-alpha (TNF- α), and interleukin-6 (IL-6) inEscherichia coli,Staphylococcus aureus, andCandida albicans bacteremia. Study subjects were 32 healthy male Landrace-Large White pigs, aged 10 –15 weeks and of average weight 19 ± 2 kg. Bacteremia was induced by continuous i...

There are only few drugs available to treat fungal infections, and the lack of new antifungals, along with the emergence of drug-resistant strains, results in millions of deaths/year. An unconventional approach to fight microbial infection is to exploit nutritional vulnerabilities of microorganism metabolism. The metal gallium can disrupt iron metabolism in bacteria and cancer cells, but it has not been tested against fungal pathogens such as Aspergillus and Candida. Here, we investigate in vitro activity of gallium nitrate III [Ga(NO3)3] against these human pathogens, to reveal the gallium mechanism of action and understa...

Authors: Casagrande Pierantoni D, Bernardo M, Mallardo E, Carannante N, Attanasio V, Corte L, Roscini L, Di Fiore L, Tascini C, Cardinali G Abstract A correct, fast, reliable identification method is pivotal in nosocomial environments to guide treatment strategies, whereas misidentification might lead to treatment failure. For routine identifications the Vitek system and CHROMagar are widely used but not always reliable, especially now with an increasing number of new emerging fungal pathogens that need careful identification. Here we describe two cases of candidemia, due to Candida palmioleophila previously miside...
