CONCLUSION: The present study …

Mechanisms of action of antimicrobial peptides ToAP2 and NDBP-5.7 against Candida albicans planktonic and biofilm cells.

Candida albicans is a major cause of human infections, ranging from relatively simple to treat skin and mucosal diseases to systemic life-th … oth peptides showed synergism with amphotericin B, while ToAP2 also presents a synergic effect with fluconazole. Besides, ToAP2 (6.25 µM.) was able to inhibit filamentation after 24 h of treatment and was active against both the early phase and mature biofilms of C. albicans. Finally, ToAP2 was protective in a Galleria mellonella model of infection. Altogethe …

Copper Acyl Salicylate Has Potential as an Anti-Cryptococcus Antifungal Agent.

The in vitro antifungal activity of aspirin against cryptococcal cells has been reported. However, the unwanted effects of aspirin may limit … ition by damaging cryptococcal cell membranes. Interestingly, when CAS was used in combination with fluconazole or amphotericin B, synergism was observed. Furthermore, CAS did not negatively affect the growth or metabolic activity of macrophages; rather, it sensitized those immune cells to produce interferon gamma and interleukin 6, which, in turn, might have …

Unintentional sulfonylurea toxicity due to a drug-drug interaction: a case report.

BACKGROUND: Sulfonylureas are widely used for type 2 diabetes mellitus, but these medications carry a risk of hypoglycemia. Drug-drug interactions that inhibit sulfonylurea metabolism and thus increase systemic exposure can cause unintentional sulfonylurea toxicity. CASE PRESENTATION: A 56-year-old man presented with severe, recurrent hypoglycemia. He had a history of type 2 diabetes mellitus and was taking the sulfonylurea gliclazide with no prior episodes of hypoglycemia. The onset of his hypoglycemia occurred within days after starting voriconazole and subsequently fluconazole for a fungal…

Rapid ART initiation and intensified adherence interventions should also be proposed to everyone presenting with advanced HIV disease.

Potent in vitro and in vivo antifungal activity of a small molecule host defense peptide mimic through a membrane-active mechanism.

Lethal systemic fungal infections of Candida species are increasingly common, especially in immune compromised patients. By in vitro screeni … both fluorescence and electron microscopy. The compound was highly active in vitro against numerous fluconazole-resistant clinical isolates of C. albicans and non-albicans species, and it exhibited potent, dose-dependent activity in a mouse model of invasive candidiasis, reducing kidney burden by three logs after 24 hours, and preventing mortality for up to 1 …

Antifungal therapies in murine infections by Candida kefyr.

Candida kefyr is an emerging pathogen able to cause disseminated infection, especially in immunocompromised patients. Although guidelines for the treatment of invasive candidiasis have been published, no specific recommendations against C. kefyr are available. We determine the in vitro killing activity of amphotericin B (AMB), fluconazole (FLC) and caspofungin (CFG) as well as their efficacy in a murine model of systemic infection by two C. kefyr strains. Time-kill curves of AMB, FLC and CFG were determined in final volumes of 10 ml containing the assayed drugs ranged from 0.03 to 32 μg ml-1 a…

AIM: Parenteral nutrition (PN) provides an alternative nutrition source for preterm infants who are intolerant of enteral nutrition. However … d with PNAC. The multivariate analysis showed that birth weight, sepsis, necrotising enterocolitis, fluconazole prophylaxis and the duration of PN and hospitalisation were independent risk factors for the development of PNAC (p < 0.05). However, parenteral fish oil-based lipid preparation (FOLP) did not reduce the risk of PNAC. Although PNAC was not a direct …

BACKGROUND: During a research project on fungal Candida species in patients wearing obturator treated with radiotherapy for their recurrent … DNA sequencing revealed that the isolates belong to Exophiala dermatitidis which was susceptible to fluconazole, itraconazole, ketoconazole and voriconazole. Interestingly, E. dermatitidis isolates were resistant to caspofungin and one isolate was resistant to amphotericin B. Both isolates formed biofilms comparable to that of Candida albicans. Single isolate …

Coccidioidomycosis Masquerading as Eosinophilic Ascites.

Endemic to the southwestern parts of the United States, coccidioidomycosis, also known as "Valley Fever," is a common fungal infection that … e until coccidioidal serology returned positive. We noted complete resolution of symptoms with oral fluconazole during outpatient follow-up. Disseminated coccidioidomycosis can present in an atypical fashion and may manifest as peritonitis with low SAAG EA. The finding of EA in an endemic area should raise the suspicion of coccidioidal dissemination.

Occurrence and ecological potential of pharmaceuticals and personal care products in groundwater and reservoirs in the vicinity of municipal landfills in China.

Pharmaceutical and personal care products (PPCPs), including antibiotics, azole anti-fungals, non-steroid anti-inflammatory drugs, lipid regulators, parabens, antiseptics, and bisphenol A, were investigated in groundwater and reservoirs in the vicinity of two municipal landfills in the metropolis of Guangzhou, South China. Dehydroerythromycin, sulfamethoxazole, fluconazole, salicylic acid, methylparaben, triclosan, and bisphenol A were the mostly frequently detected PPCPs in the groundwater at low ng L(-1) levels. In the reservoirs, the PPCPs were widely detected at higher frequencies and conc…

[Characterization of azole resistance mechanisms in Chilean clinical isolates of Candida albicans].

INTRODUCTION: The commensal yeast Candida albicans, can cause superficial or systemic candidiasis in susceptible hosts. In Chile, azole antifungals are the most widely used drugs in the treatment of candidiasis. In a previous study performed at our center, 2.1 and 1.6% of clinical isolates of C. albicans were found to be resistant to fluconazole and voriconazole, respectively. OBJECTIVE: To characterize the resistance mechanisms involved in azoles resistance in Chilean clinical isolates. METHODOLOGY: Eight resistant, nine susceptible-dose dependent (SDD) and 10 susceptible strains (n: 27) we…
