  Background & Objectives: It is estimated that as many as 75% of women experience at least one episode of vulvovaginal candidiasis during the lifetime and about 5% will have recurrent infections. There are clear association between vaginal candidiasis and uncontrolled diabetes mellitus. The purpose of this study was to determine whether non-diabetic women with recurrent vaginal candidiasis have an impaired glucose metabolism.

  Methods: This case-control study was carried out with 32 patients suffering from recurrent vulvovaginal candidiasis as case group and 30 control patients who had negative history of vaginal candidiasis during the previous year and had referred to the clinics for reasons other than vaginal candidiasis. The case group had referrd to the gynecology clinics three times during the previous year and were recognized to have vaginal candidiasis. They were being treated by antifungal drugs and had at least one positive candida culture. Both groups underwent standardized oral glucose tolerance test with 75-gram dose of glucose. The data were analysed using Chi-square and t-test.

  Results: Women with recurrent vaginal candidiasis had a mean body mass index greater than the control subjects (23.4 versus 21.5, p=0.001). They had no more incidences of overt or preclinical diabetes mellitus than the control subjects, but a greater proportion of them had at least one glucose concentration above the 95th percentile (p=0.015). Glucose concentrations were significantly higher in recurrent vaginal candidiasis cases than in control subjecs at 30, 60 and 75 minutes after the intake of 75-gram dose of glucose (p<0.05). This amount of glucose led to a 15.8% increase in serum glucose level in case group compared to the control group.

  Conclusion: Glucose tolerance test was mildy impaired in women with recurrent vaginal candidiasis. The plasma glucose concentration increased in 2 hours after 75 g glucose intake. Although the obtained results were not in the range of occult diabetes, it can designate the important of glucose tolerance test in women with recurrent vaginal candidiasis.

  Background & objectives: In recent decades, nanotechnology has been developing in medical field, and most of the nanoparticles are highly valuable in hygienic care. Vulvovaginitis is an infectious disease giving rise to problem in genital tract and Candida albicans is the main cause of Vulvovaginitis.

  Methods: In this study, laboratory effect of gold nanoparticles has been investigated on Candida albicans isolates obtained from patients with Vulvovaginitis. Candida spp. isolates were obtained from 200 patients referring to medical diagnostic laboratory in Isfahan city during 2013, and identified using mycological methods including germ tube, clamydoconidia formation, and culturing on chrom agar media. Antifungal effect of gold nanoparticles was evaluated in concentration of 100, 50, 25, and 12.5 ppm on Candida isolates using well diffusion and microdilution methods. Fluconazole was used as a positive control and results were analyzed by SPSS15 software using Mann-Whitney, Kruskal-Wallis and average differences analysis tests.

  Results: The most averages of clear zone diameter for gold nanoparticle were 18, 15, 12 millimeter, respectively. Minimum inhibitory and fungicidal
concentration of gold nanoparticle was determined 6.25, 12.5 ppm and for fluconazole were 50.25±19.48 and 100.50±38.96, respectively. Based on obtained results antifungal activity of gold nanoparticle was dependent to concentration.

  Conclusion: In current study, inhibitory effect of gold nanoparticles was evaluated against microorganism. Although the laboratories findings are promising, more investigation should be conducted for therapeutic standardization.

Background & objectives: Candidiasis is a fungal infection which is caused by Candida spp. Candida albicans is the most common agent of candidiasis. This infection may cause various side effects during pregnancy including prematurity, chorioamnionitis, candidal pneumonia, and systemic candidiasis of infants. This research was conducted for determining the prevalence and antibiotic resistance pattern of Candida spp, collected from pregnant women admitted to health centers in Ardabil, Iran.

Methods: Totally, 408 subjects were included in this study. Demographic data and risk factors were recorded using a questionnaire. Two swab samples were taken from vulvovaginal mucus. One swab was used for preparing smear and direct microscopic examination and the second one used for cultivating the specimen. After identification of Candida spp., antimicrobial resistance pattern was determined by disk diffusion method against Fluconazole, Ketoconazole, Clotrimazole, Nystatin and Amphotericin B. Results were interpreted according to CLSI guidelines. The data were analyzed by χ2 and t-test using SPSS-19.

Results: Out of 408 subjects, 143 cases (35%) were positive for candida spp. The Candida albicans with 119 (83.2%) cases was the most prevalent species followed by Candida glabrata, Candida krusei, Candida parpsilosis and Candida tropicalis.According to disk diffusion test, overall 116 (81.1%) isolates were resistant to Fluconazole, 100 (69.9%) to Ketoconazole, 67 (46.9%) to Clotrimazole and 25 (17.5%) to Amphotericin B. Candida spp. had a highest sensitivity (118, 82.5%) to Nystatin. For Candida albicans 97(81.5%) isolates were resistant to Fluconazole and 99(83.2%) isolates to Nystatin. For Candida glabrata 10 (90.9%) isolates were resistant to Fluconazole, and 9(81.8%) sensitive to Nystatin.

Conclusion: According to the results of this study, vulvovaginal candidiasis is prevalent among pregnant women in Ardabil and isolates were significantly resistant against commonly used antifungal drugs. Nystatin was the most effective against Candida spp. As antibiogram for fungal agents is not routinely performed, the similar periodical studies could be useful for choosing appropriate antibiotics in treatment of vulvovaginal candidiasis.
