We investigated the in vitro activity of nystatin and liposomal nystatin against 103 Candida isolates to determine the effect of both time and medium on MICs. We also compared the nystatin MICs with those of amphotericin B and fluconazole. Testing was performed in accordance with the National Committee for Clinical Laboratory Standards M27-A microdilution methodology with RPMI 1640, RPMI 1640 s...

OBJECTIVE To systematically review and assess the efficacy, different treatment protocols (formulation, dosage, and duration), and safety of nystatin for treating oral candidiasis. METHODS Four electronic databases were searched for trials published in English till July 1, 2015. Randomized controlled trials comparing nystatin with other antifungal therapies or a placebo were included. Clinica...

OBJECTIVES To evaluate the efficacy of pH-sensitive liposomes of nystatin against Cryptococcus neoformans infection in a murine model. METHODS In the present study, we investigated the antifungal activity of nystatin entrapped in pH-sensitive liposomes in a murine model. Mice infected with C. neoformans were treated with nystatin in neutral egg phosphatidylcholine (egg-PC) liposomes, as well ...

Volume changes in single L6 myoblasts (myoballs) exposed to nystatin solutions were followed on single cell level by means of quantitative video image analysis. The myoblasts swelled in nystatin solutions. The volume change was dependent on the nystatin concentration, the threshold concentration being 12.5 mumol/l of nystatin freshly dissolved in Krebs solution. The threshold effect was triphas...

Nystatin, a polyene antifungal antibiotic, is a cholesterol sequestering agent. The antifungal agent alters composition of the plasma membrane of eukaryotic cells, whereas its effects on cells are poorly investigated. In the current study, we investigated the question of whether nystatin was able to induce expression of macrophage inflammatory protein-1 (MIP-1). THP-1 cells rarely express MIP-1...

OBJECTIVES/HYPOTHESIS The objective of this study was to evaluate the effectiveness of nystatin and Biotène(®) mouthwash Oral Rinse for controlling Candida in total laryngectomy (TL) patients with a tracheosophageal voice prosthesis (TEP) because Biotène(®) mouthwash Oral Rinse is a less costly alternative to nystatin and requires less adherence time. STUDY DESIGN Randomized, unblinded, cross...

OBJECTIVES We developed a novel lipid formulation of nystatin suitable for parenteral administration, nystatin-intralipid (NYT-IL), with antifungal activity and reduced toxicity in mice. We investigated the pharmacokinetics, tissue distribution and immunomodulatory effect of NYT-IL in mice. METHODS Nystatin levels in serum and organs were determined using HPLC after NYT-IL or nystatin adminis...

BACKGROUND Invasive fungal infections are a major cause of morbidity and mortality in preterm infants. The authors conducted the first prospective, randomised controlled trial of nystatin compared with fluconazole for the prevention of fungal colonisation and invasive fungal infection in very low birth weight (VLBW) neonates. METHODS During a 12-month period, all VLBW neonates were assigned r...

Nystatin interaction with liposomes mimicking fungal and mammalian membranes (ergosterol- and cholesterol-containing 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) large unilamellar vesicles, respectively) was studied by fluorescence spectroscopy. The activity of this antibiotic was also measured using a pyranine fluorescence detected K+/H+ exchange assay. Nystatin mean fluorescence li...

We show how the antibiotic nystatin may be used in conjunction with microelectrodes to resolve transepithelial conductance Gt into its components: Ga, apical membrane conductance; Gbl, basolateral membrane conductance; and Gj, junctional conductance. Mucosal addition of nystatin to rabbit urinary bladder in Na+-containing solutions caused Gt to increase severalfold to ca. 460 micrometerho/muF, ...
