Abstract
Background: Vulvovaginal candidiasis, the most common type of vaginitis, is usually caused by Candidia albicans. Patients experience a variety of symptoms. There are many types of vulvovaginal candidiasis with various microbial causes, symptoms, host circumstances, recurrence rates, and responses to treatment. The purpose of this study was to find the best method of treatment of complicated vaginitis as determined by its high prevalence, varying symptoms and signs and patient complaints.
Methods: In this open clinical trial without placebo control, we studied all patients aged 18 to 65 years, suffering from vaginitis symptoms that presented at the gynecological clinic of Arash Hospital, Tehran, Iran, during the year 2004. After obtaining informed consent, we assessed the response to a treatment of single 150 mg dose of fluconazole in one group, and sequential 150 mg doses of fluconazole in the other. The analysis was performed using SPSS statistical software (version 11).
Results: With regard to symptom severity, no significant difference was found between the groups. The rate of excoriation and fissure formation demonstrated significant difference between the two groups (p=0.048). Assessment of clinical and mycological response proved that patients with severe vaginitis treated with sequential doses of fluconazole had a better general status than those in the other group. The difference between the severity of vaginitis and positive response to the treatment in culture was not significant among patients with recurrent vaginitis.
Conclusion: Patients with mild to moderate recurrent vaginitis show better response to treatment. The high rate of positive culture on day 35 reconfirms the limitation of fluconazole and other azoles as fungistatic drugs.

Background: Vulvovaginal
candidiasis is a fungal disease with itching, and vaginal thick white
discharge. Most of
non-albicans species have less sensitivity to azoles. So, definition of candida species which lead to vulvovaginal candidiasis is very important to perfect
usage of drugs. In the present study 191 Candida isolates from 175 patients who admitted in Gynecology department of
Mahdieh Hospital during the period 1385-1387 were identified by multiplex PCR.
Methods: One hundred seventy five vaginal swab specimens from
patients were cultured on Sabouraud
Dextrose Agar (SDA). The internal transcribed spacer 1 (ITS1) region between the 18S and 5.8S rRNA genes and a
specific DNA fragment
within the ITS2 region of Candida albicans were amplified and the multiplex PCR products were separated by electrophoresis in 2% agarose gel (200 mA, 140V), visualized
by staining with ethidium bromide, and photographed.
Results: One hundred ninety one Candida isolates were identified in vaginal swab specimens
from 175 patients. In 89.7% of cases, single candida species and in 10.3% cases,
multiple candida species were isolated. C.
albicans (65.1%), C.
glabrata (13.1%), C.
tropicalis (6.2%), C. krusei (4%), C. guilliermondii (0.6%), C. parapsilosis (0.6%),
C. glabrata and C. albicans (5.7%), C. albicans and C. parapsilosis (1.1%),
C. glabrata and C. tropicalis (0.6%),
C. krusei and C.
tropicalis (0.6%), C.
albicans and C.
tropicalis (0.6%), C. krusei and C. albicans (0.6%), C. glabrata and C. krusei (0.6%), and C.
glabrata and C. krusei and
C. albicans (0.6%) were the
cause of disease.
Conclusion: Our findings suggest that, the common cause of both
recurrent and non-recurrent vulvovaginal candidiasis was C. albicans, and then C. glabrata.

Abstract
Background: Looking at the increased incidence of recurrent vulvovaginal candidiasis and refractory resulting from such non-albicans Candida species in recent decades, this study was performed aiming the use of rapid biochemical and molecular detection of drug-resistant Candida species in response to fluconazole in patients with vulvovaginal candidiasis and recurrent vulvovaginal candidiasis.
Methods: The cross-sectional study was performed at Kowsar Gynecology Center, Motahhari educational hospital and Medical Mycology Center, Faculty of Medicine, Urmia, Iran, from October 2013 to July 2015. Those patients referred to the clinic with symptoms of vaginal discharge, itching or burning that swab samples from endo-exocervix and distal fornix discharge were taken. The vaginal discharge samples submitted to Medical Mycology Center, Urmia School of Medicine for the direct microscopic examination and cultures. Identification at the level of species was performed using CHROMagar Candida and Corn meal agar media. The molecular test polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) used for confirming culture results. For the susceptibility assay, disc diffusion method was performed with fluconazole and clotrimazole.
Results: In these study 198 samples collected from patients with symptoms of vulvovaginal candidiasis, 77 vulvovaginal candidiasis cases were identified. Candida species are common in primary and recurrent cases in terms of frequency, Candida albicans (85.7%), Candida krusei (10.2%) and Candida glabrata (4.1%) were identified respectively. Total of 27 cases of recurrent vulvovaginal candidiasis, 10 cases were resistant to both clotrimazole and fluconazole (37%) was observed that the most common species are resistant to treatment were Candida albicans by (82.1%), Candida krusei (14.3%) and Candida glabrata (3.6%) respectively. Drug resistance in Candida albicans, Candida krusei and Candida glabrata causing recurrent vulvovaginal candidiasis included 69.1%, 75% and 100% respectively.
Conclusion: Our findings have shown frequency of resistant non-albicans Candida species to fluconazole and clotrimazole is increasing. There is a considerable difference between Candida albicans and non-albicans species, Candida glabrata for the resistance to fluconazole and clotrimazole. |

Abstract
Background: Vulvovaginal candidiasis (VVC) is a common infection, affecting up to 75% of women during their lifetimes. Approximately 5% of patients may experience recurrent VVC. Candida albicans is the most common causative agent of VVC. The objectives of this study were identification of candida species isolated of women with vulvovaginal candidiasis by molecular method in Arak city.
Methods: In this descriptive cross-sectional study, between Jun 2015 to March 2016 from 210 patients with vulvovaginal candidiasis referred to gynecology and obstetrics clinics in Arak city, Iran. Vaginal sampling was performed by wet sterile swabs. Samples were collected from vaginal discharge, vaginal posterior fornix, and sides of the vaginal wall. The swabs were investigated for direct exam and cultured on Sabouraud’s dextrose agar medium contain chloramphenicol. Yeast isolates DNA were identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Fungal genomic DNA was extracted from each isolate colony, glass bead method and after amplification of ITS1-ITS4 region with PCR assay, digested by MSP I restriction enzyme.
Results: From 210 patients with vulvovaginitis, 95 (45.2%) patients showed VVC. These patients were positive for Candida growth in culture and were infected with one Candida species. The age range of women with vulvovaginitis was between 14-60 years and the most VVC cases were in age group of 21-30 years. The most common Candida species isolated were Candida. albicans (70.5%), C. glabrata (20%), C. tropicalis (7.4%) and C. parapsilosis (2.1%).
Conclusion: Regarding to the results of this study, C. albicans was the most common Candida species, isolated from patients with vulvovaginal candidiasis and approximately 30% of this infection causing by non-albicans species of Candida.

Abstract
Background: Vaginal candidiasis is common in during pregnancy. It may lead to complications like abortions, premature birth, low birth weight, chorioamnionitis and fungal systemic neonatal infection. The aim of present study was identification of Candida species by mycological and molecular methods in pregnant women with vaginal candidiasis.
Methods: This cross-sectional study was performed on 80 pregnant women with or without clinical symptoms of vulvovaginal candidiasis referred to Shahid Noorani Talesh Hospital, Gilan University of Medical Sciences, Iran, from April to December 2015 (8 months). All specimens were examined by direct microscopy and culture on CHROMagar Candida medium for isolation and differentiation of major clinical-significant Candida species (spp.). Cultured media were incubated at 35 °C for 48 hours and evaluated based on color and number of grown colonies. If no growth was observed, the media were incubated for several additional days. Subcultures were done on Sabouraud dextrose agar (Merck, Germany) and Corn meal agar with Tween 80 media (Micromedia, Hungary) for further study. Identification of Candida spp. carried out by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
Results: In this study, vulvovaginal candidiasis was observed in 20 (25%) patients. Twenty-two isolates were obtained from culture of specimens on CHROMagar Candida medium (Paris, France). The most common isolated species was Candida albicans 16 (72.8%) and followed by Candida glabrata 5 (22.7%), Candida tropicalis 3 (13.6%) and Candida krusei 1 (4.5%) cases. Two patients had mixed infection with 2 different Candida species (C. albicans and C. glabrata) While using PCR-RFLP method, the Candida species were identified as 13 (59.1%) Candida albicans, 5 (22.7%) Candida glabra, 3 (13.6%) Candida tropicalis and 1 (4.5%) Candida krusei cases, respectively. In direct examination were seen yeast budding cells and pseudohyphae in 8 culture positive specimens. In the present study, results of conventional mycological method in differentiation of Candida spp. were consistent with molecular results in 80% of cases. There was also significant correlation between vulvovaginal candidiasis with clinical symptoms (P<0.0001), including diabetes mellitus (P<0.014), and taking antibacterial drugs (P<0.003) in pregnant women.
Conclusion: PCR-RFLP was able to identify correctly the Candida spp. as a complementary method.
