Abstract
Approximately 70-75% of women will have vulvovaginal candidosis (VVC) at least once in their lifetime. In premenopausal, pregnant, asymptomatic and healthy women and women with acute VVC, Candida albicans is the predominant species. The diagnosis of VVC should be based on clinical symptoms and microscopic detection of pseudohyphae. Symptoms alone do not allow reliable differentiation of the causes of vaginitis. In recurrent or complicated cases, diagnostics should involve fungal culture with species identification. Serological determination of antibody titres has no role in VVC. Before the induction of therapy, VVC should always be medically confirmed. Acute VVC can be treated with local imidazoles, polyenes or ciclopirox olamine, using vaginal tablets, ovules or creams. Triazoles can also be prescribed orally, together with antifungal creams, for the treatment of the vulva. Commonly available antimycotics are generally well tolerated, and the different regimens show similarly good results. Antiseptics are potentially effective but act against the physiological vaginal flora. Neither a woman with asymptomatic colonisation nor an asymptomatic sexual partner should be treated. Women with chronic recurrent Candida albicans vulvovaginitis should undergo dose-reducing maintenance therapy with oral triazoles. Unnecessary antimycotic therapies should always be avoided, and non-albicans vaginitis should be treated with alternative antifungal agents. In the last 6 weeks of pregnancy, women should receive antifungal treatment to reduce the risk of vertical transmission, oral thrush and diaper dermatitis of the newborn. Local treatment is preferred during pregnancy.

Abstract
Background and Purpose: The aim of the current study was to investigate the epidemiology of vulvovaginal candidiasis (VVC) and recurrent VVC (RVVC), as well as the antifungal susceptibility patterns of Candida species isolates. Materials and Methods: A cross-sectional study was carried out on 260 women suspected of VVC from February 2017 to January 2018. In order to identify Candida species isolated from the genital tracts, the isolates were subjected to polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) using enzymes Msp I and sequencing. Moreover, antifungal susceptibility testing was performed according to the Clinical and Laboratory Standards Institute guidelines (M27-A3). Results: Out of 250 subjects, 75 (28.8%) patients were affected by VVC, out of whom 15 (20%) cases had RVVC. Among the Candida species, C. albicans was the most common species (42/95; 44.21%), followed by C. lusitaniae (18/95; 18.95%), C. parapsilosis (13/95; 13.69%), C. glabrata (8/95; 8.42%), C. kefyr (6/95; 6.31%), C. famata (5/95; 5.26%), C. africana (2/95; 2.11%), and C. orthopsilosis (1/95; 1.05%), respectively. Multiple Candida species were observed in 28% (21/75) of the patients. Nystatin showed the narrowest range of minimum inhibitory concentration (MIC) (0.25-16 μg/ml) against all Candida strains, whereas fluconazole (0.063-64 μg/ml) demonstrated the widest MIC range. In the current study, C. lusitaniae, as the second most common causative agent of VVC, was susceptible to all antifungal agents. Furthermore, 61.1% of C. lusitaniae isolates were inhibited at a concentration of ≤ 2 μg/ml, while 38.9% (n=7) of them exhibited fluconazole MICs above the epidemiologic cutoff values (ECV). Candida species showed the highest overall resistance against fluconazole (61.3%), followed by itraconazole (45.2%) and caspofungin (23.7%). All of C. albicans strains were resistant to itraconazole with a MIC value of ≥ 1 μg/ml; in addition, 87.5% of them were resistant to fluconazole. Moreover, 100% and 87.5% of C. glabrata strains were resistant to caspofungin and fluconazole, respectively. Conclusion: As the findings revealed, the majority of VVC cases were caused by non-albicans Candida species which were often more resistant to antifungal agents. Candida lusitaniae generally had fluconazole MICs above the ECV. Given the propensity of C. lusitaniae to develop resistance under drug pressure, antifungals should be administered with caution. The emergence of these species justify the epidemiological surveillance surveys to watch out the distribution of yeast species.

Abstract
The oestrogenised vagina is colonised by Candida species in at least 20% of women; in late pregnancy and in immunosuppressed patients, this increases to at least 30%. In most cases, Candida albicans is involved. Host factors, particularly local defence mechanisms, gene polymorphisms, allergies, serum glucose levels, antibiotics, psycho-social stress and oestrogens influence the risk of candidal vulvovaginitis. Non-albicans species, particularly Candida glabrata, and in rare cases also Saccharomyces cerevisiae, cause less than 10% of all cases of vulvovaginitis with some regional variation; these are generally associated with milder signs and symptoms than normally seen with a C. albicans-associated vaginitis. Typical symptoms include premenstrual itching, burning, redness and odourless discharge. Although itching and redness of the introitus and vagina are typical symptoms, only 35-40% of women reporting genital itching in fact suffer from vulvovaginal candidosis. Medical history, clinical examination and microscopic examination of vaginal content using 400× optical magnification, or preferably phase contrast microscopy, are essential for diagnosis. In clinically and microscopically unclear cases and in chronically recurring cases, a fungal culture for pathogen determination should be performed. In the event of non-C. albicans species, the minimum inhibitory concentration (MIC) should also be determined. Chronic mucocutaneous candidosis, a rarer disorder which can occur in both sexes, has other causes and requires different diagnostic and treatment measures. Treatment with all antimycotic agents on the market (polyenes such as nystatin; imidazoles such as clotrimazole; and many others including ciclopirox olamine) is easy to administer in acute cases and is successful in more than 80% of cases. All vaginal preparations of polyenes, imidazoles and ciclopirox olamine and oral triazoles (fluconazole, itraconazole) are equally effective (Table ); however, oral triazoles should not be administered during pregnancy according to the manufacturers. C. glabrata is not sufficiently sensitive to the usual dosages of antimycotic agents approved for gynaecological use. In other countries, vaginal suppositories of boric acid (600 mg, 1-2 times daily for 14 days) or flucytosine are recommended. Boric acid treatment is not allowed in Germany and flucytosine is not available. Eight hundred-milligram oral fluconazole per day for 2-3 weeks is therefore recommended in Germany. Due to the clinical persistence of C. glabrata despite treatment with high-dose fluconazole, oral posaconazole and, more recently, echinocandins such as micafungin are under discussion; echinocandins are very expensive, are not approved for this indication and are not supported by clinical evidence of their efficacy. In cases of vulvovaginal candidosis, resistance to C. albicans does not play a significant role in the use of polyenes or azoles. Candida krusei is resistant to the triazoles, fluconazole and itraconazole. For this reason, local imidazole, ciclopirox olamine or nystatin should be used. There are no studies to support this recommendation, however. Side effects, toxicity, embryotoxicity and allergies are not clinically significant. Vaginal treatment with clotrimazole in the first trimester of a pregnancy reduces the rate of premature births. Although it is not necessary to treat a vaginal colonisation of Candida in healthy women, vaginal administration of antimycotics is often recommended in the third trimester of pregnancy in Germany to reduce the rate of oral thrush and napkin dermatitis in healthy full-term newborns. Chronic recurrent vulvovaginal candidosis continues to be treated in intervals using suppressive therapy as long as immunological treatments are not available. The relapse rate associated with weekly or monthly oral fluconazole treatment over 6 months is approximately 50% after the conclusion of suppressive therapy according to current studies. Good results have been achieved with a fluconazole regimen using an initial 200 mg fluconazole per day on 3 days in the first week and a dosage-reduced maintenance therapy with 200 mg once a month for 1 year when the patient is free of symptoms and fungal infection (Table ). Future studies should include Candida autovaccination, antibodies to Candida virulence factors and other immunological experiments. Probiotics with appropriate lactobacillus strains should also be examined in future studies on the basis of encouraging initial results. Because of the high rate of false indications, OTC treatment (self-treatment by the patient) should be discouraged.

Abstract
BACKGROUND Available literature concerning the epidemiologic or clinical features of vulvovaginal candidiasis commonly reports that: 75% of women will experience an episode of vulvovaginal candidiasis in their lifetimes, 50% of whom will experience at least a second episode, and 5-10% of all women will experience recurrent vulvovaginal candidiasis (≥4 episodes/1 year). In this debate we traced the three commonly cited statistics to their presumed origins. DISCUSSION It is apparent that these figures were inadequately documented and lacked supporting epidemiologic evidence. Population-based studies are needed to make reliable estimates of the lifetime risk of vulvovaginal candidiasis and the proportion of women who experience recurrent candidiasis. SUMMARY The extent to which vulvovaginal candidiasis is a source of population-level morbidity remains uncertain.

Abstract
This work was carried out to study the association between lifestyle, health-care practices and incidence of recurrent vulvovaginal candidosis (RVVC) among young women in south eastern Nigeria. It was a multicentre case-control study of 176 women aged between 20 and 35 years recruited from the designated health facilities. Lifestyle and health-care practice structured questionnaires were used to survey the participants. Clinical examination was performed and vaginal swabs were taken from participants for microscopy, culture and sensitivity. The germ tube test was performed for identification of Candida albicans. The results of this study showed that frequent douching with water or other fluids (odds ratio [OR](adjusted) = 2.41, 95% confidence interval [CI] = 1.25-4.66, P = 0.000), wearing tight nylon/synthetic underwear (OR(adjusted) = 4.76, 95% CI = 2.28-9.95, P = 0.000), alternative medical treatment for repeated or recalcitrant cases (OR(adjusted) = 4.84, 95% CI = 2.94-15.91, P = 0.000), were significantly associated with higher odds for RVVC and self-diagnosis and use of over-the-counter antifungal medications (OR(adjusted) = 4.61, 95% CI = 2.29-9.32, P = 0.000) were associated with RVVC. Results of the fungal cultures showed that C. albicans and non-C. albicans were isolated from 83.7% and 16.3% of participants, respectively. Our results supported the association between some of the hypothesized risk factors and the occurrence of RVVC.

Abstract
Candida (C.) species colonize the estrogenized vagina in at least 20% of all women. This statistic rises to 30% in late pregnancy and in immunosuppressed patients. The most often occurring species is Candida albicans. Host factors, especially local defense deficiencies, gene polymorphisms, allergic factors, serum glucose levels, antibiotics, psychosocial stress and estrogens influence the risk for a Candida vulvovaginitis. In less than 10% of all cases, non-albicans species, especially C. glabrata, but in rare cases also Saccharomyces cerevisiae, cause a vulvovaginitis, often with fewer clinical signs and symptoms. Typical symptoms include premenstrual itching, burning, redness and non-odorous discharge. Although pruritus and inflammation of the vaginal introitus are typical symptoms, only less than 50% of women with genital pruritus suffer from a Candida vulvovaginitis. Diagnostic tools are anamnesis, evaluation of clinical signs, the microscopic investigation of the vaginal fluid by phase contrast (400 x), vaginal pH-value and, in clinically and microscopically uncertain or in recurrent cases, yeast culture with species determination. The success rate for treatment of acute vaginal candidosis is approximately 80%. Vaginal preparations containing polyenes, imidazoles and ciclopiroxolamine or oral triazoles, which are not allowed during pregnancy, are all equally effective. C. glabrata is resistant to the usual dosages of all local antimycotics. Therefore, vaginal boric acid suppositories or vaginal flucytosine are recommended, but not allowed or available in all countries. Therefore, high doses of 800 mg fluconazole/day for 2-3 weeks are recommended in Germany. Due to increasing resistence, oral posaconazole 2 × 400 mg/day plus local ciclopiroxolamine or nystatin for 15 days was discussed. C. krusei is resistant to triazoles. Side effects, toxicity, embryotoxicity and allergy are not clinically important. A vaginal clotrimazole treatment in the first trimester of pregnancy has shown to reduce the rate of preterm births in two studies. Resistance of C. albicans does not play a clinically important role in vulvovaginal candidosis. Although it is not necessary to treat vaginal candida colonization in healthy women, it is recommended in the third trimester of pregnancy in Germany, because the rate of oral thrush and diaper dermatitis in mature healthy newborns, induced by the colonization during vaginal delivery, is significantly reduced through prophylaxis. Chronic recurrent vulvovaginal candidosis requires a "chronic recurrent" suppression therapy, until immunological treatment becomes available. Weekly to monthly oral fluconazole regimes suppress relapses well, but cessation of therapy after 6 or 12 months leads to relapses in 50% of cases. Decreasing-dose maintenance regime of 200 mg fluconazole from an initial 3 times a week to once monthly (Donders 2008) leads to more acceptable results. Future studies should include candida autovaccination, antibodies against candida virulence factors and other immunological trials. Probiotics should also be considered in further studies. Over the counter (OTC) treatment must be reduced.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is one of the most common fungal infections that recur frequently in HIV infected women. Symptoms of VVC are pruritis, discomfort, dyspareunia, and dysuria. Vulval infection presents as a morbiliform rash that may extend to the thighs. Vaginal infection is associated with white discharge, and plaques are seen on erythematous vaginal walls.Even though rarely or never resulting in systemic fungal infection or mortality, left untreated these lesions contribute considerably to the morbidity associated with HIV infection. Prevention and treatment of this condition is an essential part of maintaining the quality of life for these individuals. OBJECTIVES -To compare the efficacy of various antifungals given vaginally or orally for the treatment and prophylaxis of VVC in HIV-infected women and to evaluate the risks of the same. SEARCH STRATEGY The search strategy was comprehensive, iterative and based on that of the HIV/AIDS Cochrane Review Group. The aim was to locate all relevant trials, irrespective of publication status or language. Electronic databases :CENTRAL,Medline, EMBASE, LILACS and CINAHL were searched for randomised controlled trials for the years 1980 to 1st October 2010. WHO ICTRP site and other relevant web sites were also searched for conference abstracts. SELECTION CRITERIA Randomised controlled trials (RCTs) of palliative, preventative or curative therapy were considered. Participants were HIV positive women receiving one or more of the following:treatment / prophylaxis for VVC or HAART(Highly Active Antiretroviral Therapy). DATA COLLECTION AND ANALYSIS Three authors independently assessed the methodological quality of the trials and extracted data. The quality of the evidence generated was graded using the GRADE PRO approach. MAIN RESULTS Our search did not yield any trial investigating treatment of VVC in HIV positive women.Two trials dealing with prophylaxis were eligible for inclusion.One trial (n= 323) favoured the use of weekly Fluconazole as compared to placebo (RR 0.68; 95% CI 0.47 to 0.97).The second trial with three arms of comparison;Clotrimazole,Lactobacillus and Placebo gave no definitive results in preventing an episode of VVC. Clotrimazole against placebo (RR 0.49; 95% CI 0.22 to 1.09), Clotrimazole against lactobacillus (RR 1.11; 95% CI 0.45 to 2.76) and lactobacillus against placebo (RR 0.54 ;95% CI 0.26 to 1.13). AUTHORS' CONCLUSIONS Implications for practiceNo trials were found addressing treatment of VVC in HIV positive women.In comparison to placebo,Fluconazole was found to be an effective preventative intervention. However, the potential for resistant Candida organisms to develop might impact the feasibility of implementation.Direction of findings suggests that Clotrimazole and Lactobacillus improved the prophylactic outcomes when compared to placebo.Implications for research There is a need to evaluate drugs and drug regimens for VVC treatment and prophylaxis in HIV positive women through randomised clinical trials. Development of resistance to azoles remains under-studied and more work must be done in this area, so as to determine whether routine prophylaxis for VVC is at all needed or whether adequate ART would be sufficient to prevent recurrent VVC. The viral load in vaginal secretions with or without treatment or prophylaxis has not been studied, this is very relevant to the spread of HIV.

Abstract
Despite therapeutic advances, vulvovaginal candidosis remains a common problem worldwide, affecting all strata of society. Understanding of anti-candida host defence mechanisms in the vagina has developed slowly and, despite a growing list of recognised risk factors, a fundamental grasp of pathogenic mechanisms continues to elude us. The absence of rapid, simple, and inexpensive diagnostic tests continues to result in both overdiagnosis and underdiagnosis of vulvovaginal candidosis. I review the epidemiology and pathogenesis of this infection, and also discuss management strategies.

Abstract
Vulvovaginal candidiasis (VVC) remains a common cause of morbidity, with three-quarters of women affected during their lifetimes. Use of antibiotics is an acknowledged trigger for VVC, which adversely affects women's physical and emotional health. Knowledge of patterns of genital Candida species-level identification is important for management, as Candida species other than Candida albicans often fail first-line treatment. A community sample of women with no vaginal symptoms, and who were prescribed antibiotics, was recruited into this study, where the incidence of genital colonization by various Candida species was documented, as well as symptoms of VVC plus relevant associations, before and after treatment with antibiotics. Self-collected low vaginal swabs were taken prior to and 8 days after completion of antibiotic treatment, and data on various potential risk factors for VVC were collected simultaneously, with complete data being available for 233 participants. Baseline Candida species colonization was present in 21% of women (95% confidence intervals [CI], 17% to 27%), rising to 37% (95% CI, 31% to 44%) after antibiotic treatment. The primary species detected for either period was C. albicans (73%), with Candida glabrata detected in around 20%. Self-assessed proneness to VVC after antibiotic treatment and baseline colonization with Candida spp. were significantly associated with symptomatic VVC after antibiotic treatment. For microbiologically proven candidiasis, VVC symptoms had a sensitivity of 57% and a specificity of 91%. When physicians prescribe antibiotics, the history of risk of VVC is one issue that physicians should discuss with women, particularly those who are self-identified as being prone to VVC. Furthermore, we recommend that definitive microbiological diagnoses be made for women with recurrent symptoms or those failing initial treatment, to guide appropriate therapy.

Abstract
Vulvovaginal candidiasis is one of the most frequent infections of the female genital tract with a high incidence. Although numerous antimycotical agents are available for treatment of yeast vaginitis, there are few comparative data on the in vivo and in vitro activity of these drugs. The aim of this open, randomized, and comparative study was to determine in vivo and in vitro effectiveness of the 3 systemic antifungal agents: terbinafine and 2 azoles (itraconazole and fluconazole) in the treatment of patients with Vulvovaginal candidiasis. A total of 44 patients who had signs and symptoms of Vulvovaginal candidiasis were recruited for the study. Patients were randomly assigned to 3 groups: terbinafine 500 mg/d orally was used for 7 days, itraconazole 200 mg/d orally was used for 7 days, and fluconazole 150 mg orally was used as a single dose. Both clinical and mycologic examinations were performed for posttreatment assessment at week 4. This study revealed a clinical cure rate 33.3% for terbinafine, 60% for itraconazole, and 66.6% for fluconazole (P>0.05). Mycologic cure rates were 33.3%, 10%, and 66.6% respectively (P<0.05). Overall cure rates were 33.3%, 10%, and 53.3% (P>0.05). Terbinafine could be an alternative treatment option in Vulvovaginal candidiasis because there were no significant differences in the clinical and overall cure rates among 3 antifungal agents. However, terbinafine could not be suggested as a first-line treatment in Vulvovaginal candidiasis. Systemic use of terbinafine in larger numbers of cases may give more information about the effectiveness of this drug in the treatment of patients with vulvovaginal candidiasis.

Abstract
Eight Italian hospital or University gynecology clinics participated in a prospective survey of patients with culture-confirmed symptomatic vulvovaginal candidiasis (VVC) (October 1999 to March 2001). Of 1138 patients recruited in the study, 931 were evaluable. A recent history of VVC was documented in 43.5% patients (358/823) with a mean number of 2.9+/-2.7 episodes per patient (N=302). A total of 77 patients (10.0%) had a history of recurrent VVC (four and more episodes in a 12-month period). The most frequent associated factors were related to life style: synthetic fabric underwear, vaginal douching and bike, training bike and motorbike (about 1/3 each). Oral contraception was found in 20.8% patients, recent antibiotic use in 15.9% patients, current pregnancy concerned 10.3% patients while 3.4% patients were taking hormonal replacement therapy. Diabetes, corticosteroids or HIV were rarely encountered. Yeast was documented by direct microscopy in 78.3% patients (448/572). A positive culture was obtained in 98.3% patients (909/925). Candida albicans was the predominant species (77.1%), followed by Candida glabrata (14.6%) and Candida krusei (4.0%). With the exception of one center with a lower proportion of C. albicans, this latter represented between 75 and 85% of the isolates. Overall, this study confirmed the preponderant role played by C. albicans in either sporadic and recurrent VVC.

Abstract
Since the advent of the antimicrobial era, single-dose therapy has been a valuable tool in the management of genital infection. Most of the common sexually transmitted infections (STIs) such as gonorrhoea, syphilis, trichomoniasis and chancroid can be treated in this way, as can genital infections which are not sexually transmitted such as bacterial vaginosis and genital tract candidiasis. Until recently, treatment for Chlamydia trachomatis infection required a multi-dose regimen, but single-dose azithromycin has now been shown to be an effective and acceptable alternative to this. Unfortunately, eradicative therapy has proven to be elusive for the viral STIs such as genital herpes simplex infection, human papilloma virus infection and human immunodeficiency virus (HIV) infection. The main advantage of single-dose therapy lies in its convenience and in its ability to ensure virtually 100% compliance. This addresses the problems of reduced clinical efficacy and the difficulties in assessing the response to therapy which complicates poor treatment compliance. However, some single-dose regimens for STIs do have drawbacks, particularly in certain situations. This may be with respect to efficacy, for example in syphilis with single-dose benzathine penicillin therapy, particularly for pregnant women and individuals infected with HI. Alternatively, it may involve toxicity, for example with single-dose metronidazole therapy for trichomoniasis or bacterial vaginosis where a higher rate of gastrointestinal adverse effects may be expected than if a lower multi-dose regimen is used. In addition, single-dose therapy, for example with nevirapine, given to the mother in labour and to the baby after delivery significantly reduces the risk of mother to child HIV transmission, but resistance mutations are frequently detected in the viral genome after the brief exposure to the drug, which could jeopardise its future use. Single-dose therapy clearly has both advantages and disadvantages. We have reviewed a range of these in a variety of situations, focussing on their applications, effectiveness, compliance and toxicity, highlighting how single-dose therapy may be a double-edged sword.

Abstract
Candida albicans and related species pathogenic for man become resistant to antifungal agents, in particular triazole compounds, by expression of efflux pumps that reduce drug accumulation, alteration of the structure or concentration of antifungal target proteins, and alteration of membrane sterol composition. The clinical consequences of antifungal resistance can be seen in treatment failures in patients and in changes in the prevalences of Candida species causing disease. These effects were seen unequivocally in HIV-infected patients with oropharyngeal candida infections, but their incidence has decreased dramatically with the introduction of highly active antiretroviral therapy. The evidence for similar emergence of antifungal-resistant yeast strains and species in other types of candida infections is confounded by non-standardised susceptibility testing methods and definitions of a resistant fungal isolate. Recent large-scale surveys of yeasts isolated from blood cultures, based on standardised methodology and resistance definitions, do not support the view that antifungal resistance in pathogenic yeasts constitutes a significant or growing therapeutic problem.

Abstract
OBJECTIVE To monitor yeasts isolated from women during and between episodes of recurrent vulvo-vaginal candidosis (VVC) to determine whether vaginal relapse or re-infection occurred. METHODS Women presenting at the genitourinary medicine clinic with signs and symptoms of VVC were recruited to the study (n = 121). A vaginal washing, high vaginal swab (HVS) and rectal swab were taken and the women treated with a single 500 mg clotrimazole pessary. Women were asked to re-attend after 1, 4, and 12 weeks, or when the VVC recurred, when vaginal washings and HVS were repeated. Candida isolates recovered were strain typed using the Ca3 probe and their similarity assessed. Antifungal susceptibility to fluconazole and clotrimazole were determined. RESULTS Of the women recruited, 47 completed the study, either returning for four visits or suffering a recurrence during the study period. Of the 22 women who experienced recurrence, the same strain was responsible for the initial and recurrent episode in 17 women. For the remaining five women, four had strain replacement and one had a change of species. None of the isolates recovered from the women demonstrated resistance to either clotrimazole or fluconazole. CONCLUSIONS Our findings support the theory of vaginal relapse and thus may support the use of more prolonged courses of antifungal therapy initially to increase the chances of eradication of the yeast.
