[Comparision of antifungal effect of Nystatin alone and in combination with nanosilver particles against candida species isolated from chronic candidal vaginitis]

Nystatin is a polyene with antifungal effect which is used in treatment of cutaneous and mucocutaneous candidiasis in diverse forms. Increasing its utilization in recent years has led to predominant increasing of resistances. Nowadays for increasing of antifungal effect and decreasing of resistance and side effects of drugs they are used in combination with each other. So we decided to investigate antifungal effect of Nystatin in combination with nanosilver particles. This was an experimental study which has been accomplished on 30 samples of isolated candida species from patients effected to chronic candidal vaginitis. In this study the antifungal effects of Nystatin and silver nanoparticles each of them alone and in combination with each other by microdilution broth, were examined. Findings were described on the base of logestic regression and man-vitni exam. Findings suggested that Nystatin was able to inhibit the growth of candida species at an expanded range of concentration between 16-128 microgeram per milliliter. As well antifungal activity of Nystatin with silver nanoparticles was increased in comparision with using Nystatin alone. Introduce of nanosilver in drug formation of Nystatin can be useful in treatment of chronic vaginal candidiasis

[Comparision of antifungal effect of fluconazole alone and in combination with nanosilver particles against candida species isolated from chronic candidal vulvovaginitis]

Candidal vulvovaginitis is a female genital infection that is occured by the over growth of candida species and specially Candida - albicans and occasionally it appears as recurrent and chronic and resist to therapy. Fluconazole is one of the current drugs that is used in treatment of this disease and sometimes resistance is observed to this. Therefore indirection of making the therapy better we decided to investigate the activitiy of fluconazole in combination with silver nanoparticles against candida species isolated from chronic and recurrent candidal vaginitis. This was an experimental study with convenient sampling that was performed on 30 patients. All specimens were examined in direct microscopy, culturingand differential tests to identify different candida species from each other such as culture on candida chrom agar, germ tube, temperature test and sugar assimilation with API. Then the antifungal effects of fluconazole and silver nanoparticles, each of them alone and in combination with each other, were examined .Findings were described on the base of logestic regression and man-vitni exam. In our study 30 specimens of chronic genital candidiasis were diagnosed with isolated agents Candida albicans, glabrata, krusei, tropicalis, parapsilosis and Candida famata respectively. Also findings suggested that fluconazole was able to inhibit the growth of candida species at an expanded range of concentration between 4-128 microgeram per milliliter.As well antifungal activity of Fluconazole with silver nanoparticles was increased in comparision with using Fluconazole alone. For the prevention of recurrent cases and to stabilish correct diagnosis it is essential to carry out sensitivity and diagnostic tests in laboratory and also administration of silver nanoparticle in combination with fluconazole in drug formulation for topical uses in treatment of chronic vaginal candidiasis and inhibition of recurrent cases, can useful

[Evaluation of serological diagnosis indirect immunofluorescence and ELISA in comparison to direct examination and culture in vulvovaginal candidiasis]

Vulvovaginal candidiasis occurs due to the overgrowth of candida in genital system mucosa of females. Symptoms and signs of vulvovaginal candidiasis are unspecific, therefore diagnosis is not certain. The aim of this research was comparison of the result of indirect immunofluorescence and ELISA with culture and direct microscopy examination in patients with vulvovaginal candidiasis. This was a comparative-descriptive study performed on 87 patients and 50 normal cases as controls. All specimens were examined using direct microscopy, culturing and complimentary test to differentiate the candida species from each other. Serological tests such as indirect immunofluorescence and ELISA were performed on sera of the patients. To compare the quantitative and qualitative data, t-student test, chi-square and exact fisher test were used, if necessary. Out of 87 specimens, 50 cases were diagnosed as vulvovaginal candidiasis. The most frequent isolated pathogens were C.albicans, C.glabrata, C.kefyr, C.inconspicua and C.famata, respectively. Also, in control group, the most frequent pathogens were C.albicans, C.glabrata and C.kefyr, respectively. In this study all of normal cases were negative in indirect immunofluorescence test and in patients group 42 person [84%] were positive and 8 [16%] negative. Control participants were negative in ELISA and in patient group 40 person [80%] were positive and 10 person [20%] negative. It seems in cases that direct microscopic and culturing methods is impossible, ELISA and indirect immunofluorescence can be used as an alternative method
