Aspergillus sinusitis. (33/56)

Since 1969, 79 cases of fungal maxillary sinusitis have been diagnosed. Forty-nine were due to Aspergillus fumigatus. There were no underlying diseases which depressed cellular immunity and no patient was receiving immunosuppressive drugs or corticosteroids. Most patients had received antibacterial therapy before the appearance of FMS. Treatment was by surgery, nystatin and econazole.  (+info)

Pharmacokinetics of imidazole antimycotics. (34/56)

According to data on the imidazole antimycotics at present on the market, none of these products satisfactorily fills the gaps which exist in the treatment for mycoses of internal organs, although they have brought considerable progress in the topical treatment of mycoses. On the basis of their very broad spectrum and high intensity of activity under suitable test conditions, and the comparatively tolerable amount of side effects in man, the present imidazole antimycotics are considered to be an encouraging start for future development of derivatives which will lead to products with considerably better pharmacokinetic, and therefore better therapeutic, properties.  (+info)

Influence of the corneal epithelium on the efficacy of topical antifungal agents. (35/56)

A model of deep stromal Candida albicans infection was established by injecting 25 microliters of a suspension containing 5 X 10(9) colony forming units/ml of the yeast into corneas of pigmented rabbits. In this model, the infection lasts for more than 8 days. Using quantitative techniques, the authors compared the efficacy of six topical antifungal agents in the presence of an intact epithelium and in corneas debrided of epithelium. In corneas debrided on a daily basis, the polyenes (amphotericin B 0.15% and 0.075% and natamycin 5%) exhibited a significant antifungal effect. When the epithelium was left intact, 5% natamycin and 0.075% amphotericin B were without effect, while the efficacy of the 0.15% preparation of amphotericin B was much reduced. Removal of the epithelium appeared to affect adversely the efficacy of flucytosine. The imidazoles were not efficacious in this model.  (+info)

Clotrimazole and econazole in the treatment of vaginal candidosis. A single-blind comparison. (36/56)

Clotrimazole and econazole used as treatment for vaginal candidosis are both effective when given for three days. In a single-blind controlled study of 110 women followed for 14 days the efficacy of treatment with clotrimazole and econazole for three days was equal. Eighty-six per cent of the group treated with clotrimazole were mycologically clear at 14 days compared with 90% of those treated with econazole. Both treatment regimens were equally acceptable to the patients and no side effects were reported.  (+info)

A clinical study of econazole cream in the treatment of fungal skin infections. (37/56)

An open assessment of the efficacy of econazole nitrate (Pevaryl) cream in the treatment of 140 patients with proven dermatomycoses was conducted at five university health centres. Specimens were obtained from 129 patients at the end of treatment and 121 (93.8 per cent) showed no evidence of fungi. After a further month without treatment 108 patients reattended and, of these, 98 (90.9 per cent) remained clinically and mycologically free from infection. Trichophyton rubrum and Epidermophyton floccosum were the fungi most frequently isolated, and the distribution of species and areas of the body affected were similar for all five centres.  (+info)

Treatment of vaginal candidosis with econazole nitrate and nystatin. A comparative study. (38/56)

A study carried out to compare the efficacy of econazole nitrate and nystatin in the treatment of vaginal candidosis showed that a three-day course of econazole nitrate pessaries was as effective as a 14-day course of nystatin pessaries and is more acceptable to patients.  (+info)

In vivo antimycotic activity of naftifine. (39/56)

Naftifine, a new antifungal agent belonging chemically to the allylamines, was tested for its in vivo activity after topical application against guinea pig skin infections caused by Trichophyton mentagrophytes, T. mentagrophytes var. quinckeanum, or Microsporum racemosum. Compared with standard compounds, naftifine proved to be highly effective mycologically and clinically after topical application in the above models.  (+info)

Effect of anti-fungal imidazoles on mRNA levels and enzyme activity of inducible nitric oxide synthase. (40/56)

1. Experiments were performed to examine the effects of anti-fungal imidazole compounds (clotrimazole, econazole and miconazole) on the induction of nitric oxide (NO) synthase and subsequent production of NO in the cultured murine monocyte/macrophage cell line J774 using a specific cDNA probe for inducible NO synthase mRNA and by monitoring nitrite production. 2. Stimulation of J774 cells with lipopolysaccharide (LPS, 10 micrograms ml-1) resulted in the induction of NO synthase activity as determined by nitrite accumulation in the culture medium (48 +/- 3 nmol per 10(6) cells over 24 h). Production of nitrite was inhibited by co-incubation of cells with LPS (10 micrograms ml-1) and either dexamethasone (10 microM) or NG-monomethyl-L-arginine (L-NMMA; 0.1 mM), however, only L-NMMA was an effective inhibitor of nitrite production when added after induction of NO synthase had occurred. 3. Co-incubation of J774 cells with LPS (10 micrograms ml-1) and either clotrimazole, econazole or miconazole (1-10 microM) resulted in a concentration-dependent inhibition of nitrite production over the subsequent 24 h without any evidence for a cytotoxic effect. However, addition of these imidazoles after induction of NO synthase did not inhibit nitrite production. 4. Messenger RNA for inducible NO synthase was not detected in unstimulated J774 cells. Treatment with LPS (10 micrograms ml-1) for 4 h resulted in significant expression of mRNA for inducible NO synthase which was not altered in the presence of econazole (10 microM) but was reduced significantly by dexamethasone (10 microM). 5. These results demonstrate that anti-fungal imidazoles inhibit the production of nitric oxide by cultured J774 cells by a mechanism which appears to differ from that of dexamethasone and substrate type inhibitors of NO synthase. Furthermore, the presence of mRNA for NO synthase does not indicate the presence of functionally active NO synthase.  (+info)
