Autovaccines - potent tool against chronic vulvovaginal candidiasis.

OBJECTIVE: Our aim was to determine the effect of immunomodulatory therapy in women with chronic and recurrent vulvovaginal candidiasis (RVVC). BACKGROUND: We present recent highlights in the research into vaginal microbiome and consequences of chronic inflammation such as vulvovaginal candidiasis (VVC). VVC is a widespread vaginal infection primarily caused by Candida albicans. Experience of more than three episodes per year is defined as RVVC. METHODS: The strains were isolated from women suffering from the above infections as for the period of 2017 to 2021 and subsequently used in immunomodulatory treatment. The preparation and administration of autovaccination therapy was performed using standard methodology and procedures cited in the manuscript. RESULTS: In total, autovaccines were produced for 73 patients of whom 30 (41 %) were successfully cured by this treatment, 29 (40 %) experienced a partially successful treatment, and in the remaining 14 (19 %), the autovaccination therapy was ineffective. CONCLUSION: We provide current knowledge about alternative (autovaccine) treatment options for female patients with VVC and RVVC diseases and our experience with the outcomes after autovaccine administration that currently has a promising therapeutic potential (Tab. 2, Ref. 18).

Inflammatory invasion on human vaginal mucosa correlated with combined drug treatment and recurrence in recurrent vulvovaginal candidiasis.

AIM: Recurrent vulvovaginal candidiasis (RVVC) is a chronic, difficult to treat vaginal infection, caused by Candida species, which affects women of all ages and ethnic and social background. Most RVVC studies use animal models, and there is still a lack of observation on human tissue samples and effective therapy to reduce recurrence. MATERIALS AND METHODS: We observed CD163+ macrophages and NLRP3 expression by immunohistochemistry, also investigated bacteria and fungi co-invasion by fluorescence in situ hybridization from 144 human vaginal biopsy tissues (48 RVVC, 48 VVC, 48 healthy volunteers), and we also explored the effect of combining metronidazole in the treatment of RVVC. RESULTS: A large number of neutrophils, lymphocytes and plasma cells infiltrated the mucosa, basement membrane and submucosa, accompanied by significantly overexpressed NLRP3 inflammasome. While CD163+ macrophages often infiltrated under the basement membrane in patients with RVVC, 29.2% of cases were found Gardnerella and fungi jointly invaded the vaginal mucosas. RVVC vaginal mucosal histopathology revealed mucosal inflammatory responses dominated by neutrophils, which may involve activation of NLRP3 and immune tolerance of M2 macrophages (CD163+ ). Fluconazole combined with metronidazole can achieve higher efficiency (95.8% vs. 70.8%) and reduce the recurrence rate more (8.3% vs. 37.5%) at 6-month follow-up. CONCLUSION: Inflammatory invasion on human vaginal mucosa correlated with combined drug treatment and recurrence in RVVC. The combined medication will need to further evaluate in future.

Vulvovaginal candidiasis in a murine model of diabetes emphasizing the invasive ability of etiological agents.

Aim: To compare the pathogenesis of vulvovaginal candidiasis by three Candida species in diabetic mice. Materials & methods: Estrogenized and diabetic mice were challenged with C. albicans, C. tropicalis and C. glabrata. Results: Diabetic animals infected with C. albicans and C. tropicalis maintained the highest fungal burden, despite of high levels of proinflammatory cytokines (IL-6 and TNF-α), respectively. For C. glabrata, the results were similar in diabetic and nondiabetic groups. Conclusion:C. tropicalis was as invasive as C. albicans, and both were more effective than C. glabrata. This ability was attributed to filamentation, which may be stimulated by glucose levels from vaginal fluid. In addition, the high burden may be attributed to the apparent immunological inefficiency of the diabetic host.

Sunlight exposure, consumption of vitamin D-rich foods and vulvovaginal candidiasis in an African population: a prevalence case-control study.

BACKGROUND/OBJECTIVES: To date, only two studies have investigated the relationship between vitamin D (vitD) deficiency and candidiasis in spite of vitD's antimicrobial and immunomodulatory roles. We examined the relationship between sunlight exposure and consumption of vitD-rich foods, markers of vitD status, and vulvovaginal candidiasis (VVC) in an African population to add to the limited evidence and stimulate additional research. SUBJECTS/METHODS: Three hundred cases (females diagnosed as suffering from VVC) and three hundred controls (females diagnosed as suffering from any condition other than VVC) were selected from three health facilities in Cape Coast, Ghana. Sunlight exposure was assessed in a structured questionnaire with a food frequency questionnaire used to ascertain the frequency of consumption of vitD-rich foods. RESULTS: Self-reported low sunlight exposure was associated with 3.38 (95% CI:1.99, 5.74) increased odds of VVC. Low and moderate sunlight exposure estimated by outdoor visits was also associated with increased odds of VVC. In sensitivity analysis restricted to matched sunlight exposure data, low and moderate exposure was associated with 5.78 (95% CI: 2.57, 12.99) and 3.53 (95% CI: 1.85, 6.75) increased odds of VVC. Odds of VVC increased with decreasing levels of consumption of vitD-rich foods (Likelihood-ratio test trend p = 0.1382). In the joint analysis, low and moderate vitD intake was associated with much higher increased odds of VVC. CONCLUSIONS: Our findings should be confirmed in prospective studies and clinical trials to strengthen the evidence base for preventive action and to also inform clinical decision making.

Bacterial vaginosis, vulvovaginal candidiasis and trichomonal vaginitis among reproductive-aged women seeking primary healthcare in Sana'a city, Yemen.

BACKGROUND: In Yemen, the underlying causes of infectious vaginitis have been neglected. Therefore, this study aimed to determine the prevalence and risk factors associated with bacterial vaginosis (BV), vulvovaginal candidiasis (VVC) and trichomonal vaginitis (TV) among non-pregnant reproductive-aged women. METHODS: A cross-sectional study was conducted among 347 non-pregnant reproductive-aged women seeking primary healthcare in Sana'a city, Yemen. Data about sociodemographic characteristics, lifestyle-related behaviors, routine hygienic practices, menstrual care and history and type of contraceptive intake were collected using a structured questionnaire. Vaginal discharge samples were collected and examined for discharge characteristics and pH by a gynecologist. Then, samples were examined for BV, VVC and TV. Data were analyzed using suitable statistical tests. RESULTS: Vaginal infections were prevalent among 37.6% of reproductive-aged women, where BV was the most prevalent (27.2%). VVC was significantly higher among symptomatic women and significantly associated with itching (P = 0.005). Using bivariate analysis, the age of < 25 years (odds ratio [OR] = 1.9, 95% confidence interval [CI]: 1.16-3.10; P = 0.010) and using intrauterine contraceptive devices (IUCDs) (OR = 1.8, 95% CI: 1.09-2.89; P = 0.020) were significantly associated with BV, while history of miscarriage was significantly associated with a lower risk of BV (OR = 0.5, 95% CI: 0.31-0.85, P = 0.009). However, polygyny was significantly associated with VVC (OR = 3.4, 95% CI: 1.33-8.66; P = 0.007). Multivariable analysis confirmed that age of < 25 years and using IUCD were the independent predictors of BV, while history of miscarriage was an independent protective factor against BV. On the other hand, marriage to a polygamous husband was the independent predictor of VVC. CONCLUSIONS: More than a third of non-pregnant reproductive-aged women seeking PHC in Sana'a have single or mixed infections with BV, VVC or TV. BV is the most frequent cause of vaginitis and is significantly associated with the age of < 25 years and using IUCDs, while VVC is significantly higher among women with polygamous husbands. Health education of polygamous husbands and their wives, regular monitoring of BV among IUCD users and screening women for vaginitis before treatment are recommended.

The Vaginal Microbiota and Behavioral Factors Associated With Genital Candida albicans Detection in Reproductive-Age Women.

BACKGROUND: Vulvovaginal candidiasis is commonly diagnosed and has been associated in prospective studies with the acquisition of HIV. Little data is available on how the composition of the vaginal microbiota, and other risk factors, are associated with the molecular detection of Candida albicans-a common cause of vulvovaginal candidiasis. METHODS: In a cross-sectional study, self-collected vaginal swabs were obtained from 394 nonpregnant, reproductive-age women. C. albicans was detected using polymerase chain reaction targeting C. albicans ITS1/2 region. Vaginal microbiota was characterized by 16S rRNA gene amplicon sequencing of the V3 to V4 hypervariable regions and clustered into community state types (CSTs). Multiple logistic regression identified factors associated with C. albicans detection. RESULTS: Twenty-one percent had C. albicans detected and 46% reported vaginal symptoms in the prior 60 days. There was a 2-fold increase in the odds of C. albicans if a woman was in a L. crispatus-dominated CST compared to CSTs with low-Lactobacillus levels (adjusted odds ratio, 2.05; 95% confidence interval, 0.97-4.37). History of self-treatment with antifungals, L. crispatus relative abundance, and receptive oral sex were also significantly associated with C. albicans detection. CONCLUSIONS: A L. crispatus-dominated vaginal microbiota is thought to protect women from both development of bacterial vaginosis and incidence of sexually transmitted infections; however, our data suggest that L. crispatus is associated with increased C. albicans detection. Receptive oral sex may also be a risk factor for vaginal C. albicans colonization.

Recurrent vulvo-vaginal candidiasis in Abidjan (Côte d'Ivoire): Aetiology and associated factors.

Recurrent vulvovaginal candidiasis (RVVC) is a major health problem for sexually active women because of its severe effect on their quality of life. A thorough knowledge of their epidemiology leads to their efficient management. Therefore, a cross-sectional study was conducted in 2014 in women with leucorrhoea associated or not with other clinical signs. Recurrence was based on the occurrence of at least four annual episodes of Candida vulvo-vaginitis. An individual interview based on a questionnaire was conducted to identify the socio-demographic parameters that could be associated with the RVVC. Vaginal samples were collected at the obstetrical gynaecology department of the University Hospital of Cocody and at the Pasteur Institute of Côte d'Ivoire. On each sample, a direct examination and culture on Sabouraud-chloramphenicol medium with or without actidione were performed. Yeast identification was performed using chromogenic media (CandiSelect®4 [Bio-Rad]) and the study of sugar assimilation using the Auxacolor® 2 gallery (Bio-Rad). A total of 400 patients were included. The average age was 29.2 years (SD=7.2 years). Of these, 94 had recurrent vulvovaginal candidiasis, with a prevalence of 23.5% (CI95%: 19.49-28.02). Five species of the genus Candida have been identified: Candida albicans (59.6%), Candida glabrata (19.1%), Candida tropicalis (16%), Candida krusei (4.2%) and Candida inconspicua (1.1%). Some factors such as education level, history of sexually transmitted infection, type of underwear used, frequency of personal hygiene and type of product used for these hygiene have been associated with the occurrence of RVVCs. The occurrence of RVVCs is relatively high in our study population. Non-albicansCandida species occupy a significant place in this disease epidemiology. By addressing the factors associated with the occurrence and/or persistence of RVVCs, it will be possible to reduce their incidence in sexually active women.

Brief versus Thong Hygiene in Obstetrics and Gynecology (B-THONG): A survey study.

AIM: The aim of this study was to evaluate if thong use is associated with a higher report of urogenital infections, including urinary tract infections, yeast vaginitis and bacterial vaginosis. METHODS: A cross-sectional survey regarding underwear preferences and infectious history was designed and distributed to women via a crowdsourcing service. All survey questions related to the last 12 months. Parametric and nonparametric statistical methods were used to compare responses between thong wearers and nonthong wearers. Thong wearers were defined as women who wore a thong equal to or more than 50 % of the time. RESULTS: Nine hundred and eighty-six respondents met inclusion criteria and completed the survey; 186 (18.9%) were defined as thong wearers and 800 (81.1%) were defined as nonthong wearers in the last 12 months. Reported rates of urogenital infections in the last 12 months were not significantly different for thong wearers versus nonthong wearers. Thong use was not an independent predictor of any urogenital infection in this study. CONCLUSION: In this large cross-sectional study we found that oral sex was the only independent predictor of urinary tract infection and bacterial vaginosis, and that wearing noncotton crotch underwear was associated with yeast vaginitis. Wearing thong underwear was not associated with any urogenital infections. Medical providers should discuss sexual practices and underwear fabric, rather than style, with their patients when there is concern for urogenital infection.

Effect of intrauterine device insertion on Candida species in cervicovaginal specimen identified by polymerase chain reaction technic: A longitudinal study on Iranian women.

AIM: To assess the effects of copper T-380-A intrauterine device (IUD) insertion on Candida species in cervicovaginal specimen by a molecular method, polymerase chain reaction. METHODS: This is a longitudinal prospective study performed on 95 women attending Health Centers of Tehran, Iran in 2012, who selected copper T-380-A IUD for contraception and had no history of local or systemic antibiotics or antifungals use during the previous 2 weeks. Cervicovaginal specimens were twice collected and cultured on Sabouraud dextrose agar and CHROMagar Candida, before and 3 months after IUD insertion. Finally, a molecular method, PCR-RFLP was performed for identification of Candida species. P-values <0.05 were considered significant. RESULTS: The mean age of participants was 28 ± 7.44 years. Positive Candida cultures were significantly increased 3 months after IUD insertion (25.3% vs 11.6%, P = 0.007). The most common identified species before and after IUD insertion, were Albicans, Glabrata and then both 'Albicans & Glabrata', respectively. The prevalence of Albicans and Glabrata decreased, while both 'Albicans & Glabrata' increased insignificantly. CONCLUSION: There was more than about fourfold increase in positive Candida cultures after IUD insertion. As the prevalence of simultaneous infection with both 'Albicans & Glabrata' species which are resistant to usual treatment, increased, it seems necessary to provide more intensive follow-up care for IUD users.

Adhesion and biofilm formation of Candida parapsilosis isolated from vaginal secretions to copper intrauterine devices.

INTRODUCTION: Candida parapsilosis is one of the main species that is able to adhere to forming biofilms on inert materials. Adhesion is the first step towards the colonization and invasion of host cells during the infectious process. Among the infections, vulvovaginal candidiasis is increasingly common. The objective was to evaluate the profile of adherence and biofilm formation of eight isolates of C. parapsilosis on the metal used in intrauterine devices (IUDs). METHODS: Eight strains of C. parapsilosis presenting strong adhesion and biofilm formation properties were isolated from vaginal secretions in a previous study. To assay the adhesion and biofilm formation, copper fragments were made and cultivated in tubes containing 3 mL of phosphate-buffered saline and incubated for 6 and 24 h at 37 °C to evaluate biofilm formation. After incubation, the intensity of adherence and of biofilm formation on copper fragments were determined by performing a colony count. RESULTS: All isolates were able to form biofilms and the isolate Cp62 showed many cells joined in a planktonic mode forming biofilms. The use of an IUD is one of the main factors that favors vulvovaginal candidiasis, and the presence of copper in this device increases the chance of recurrent vulvovaginal candidiasis (CVVR) due to the ease with which species of the genus Candida can adhere to inert surfaces. CONCLUSION: This research showed that the clinical isolates studied adhered to IUD copper fragments and formed biofilms, further increasing their virulence.

Chronic vulvovaginal candidiasis in patients using a levonorgestrel-containing intrauterine device.

Chronic vulvovaginal candidiasis is usually responsive to therapy with oral antifungals. We present a case series of 13 patients with this condition who were also using a levonorgestrel intrauterine system (LNG-IUS). All cases responded to ongoing oral fluconazole therapy while the LNG-IUS was in situ. The LNG-IUS was removed in six patients and of these, two experienced clinical improvement with lower fluconazole dosage requirements and three experienced complete resolution of symptoms. One remains on fluconazole 100 mg daily.

High glucose-mediated overexpression of ICAM-1 in human vaginal epithelial cells increases adhesion of Candida albicans.

To investigate the involvement of ICAM-1 in the adhesion of Candida to the genitourinary epithelial cells in high glucose, we examined the adhesion of Candida albicans or Candida glabrata to human vaginal epithelial cells (VK2/E6E7) or human vulvovaginal epidermal cells (A431). These cells were cultured in 100, 500 or 3000 mg/dL glucose for three days and inoculated with Candida for 60 minutes. Followed by, adhering of Candida to the cells, which were counted. While the adhesion of Candida albicans to VK2/E6E7 significantly increased in the high glucose, A431 did not. We next examined the expression of ICAM-1 as a ligand on the epithelial cells. ICAM-1 expression was increased in VK2/E6E7 cultured in the high glucose; however, the expression level in A431 was not high compared with VK2/E6E7. This data suggested that ICAM-1 functions as one of ligands in the adhesion of Candida albicans to the vaginal epithelial cells in a high glucose environment. Impact statement What is already known on the subject: Candida's complement receptor is involved in the adhesion to epithelial cells. The expression of this receptor has been reported to increase as glucose concentration increases. This is considered as a contributing factor to the high risk for vulvovaginal candidiasis (VVC) in diabetes. On the host side, diabetic patients have a factor that facilitates adhesion of Candida to epithelial cells. This factor has been unknown until recently. What the results of this study add: In this study, we used a vaginal epithelial cell line and showed that the adhesion of C. albicans to cells increased at higher glucose concentrations. At the same time, ICAM-1 expression of cells also increased. Thereby, it is suggested that the expression of ICAM-1 in vaginal epithelial cells is increased by glucose such as urinary sugar in diabetic patients and is a condition for facilitating adhesion of Candida. What the implications are of these findings for clinical practice and/or further research: We expect not only host immune dysfunction but also alteration in epithelial cells will be focussed on as a cause of VVC in diabetic patients.

Risk of bacterial vaginosis, Trichomonas vaginalis and Candida albicans infection among new users of combined hormonal contraception vs LNG-IUS.

OBJECTIVE: The study assessed the risk of bacterial vaginosis, Trichomonas vaginalis and Candida albicans infection among new users of either a combined oral contraceptive pill (COC) or the levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: This prospective observational study included 430 women, without active vaginitis at inclusion, who were divided into two groups according to their chosen method of contraception: COC group (n = 236) and LNG-IUS group (n = 194). Participants were examined for bacterial vaginosis, T. vaginalis and C. albicans infection initially and then at 6 weeks, 6 months and 12 months after the start of contraceptive use. Data were collected and statistically analysed. RESULTS: The rates of acquisition of bacterial vaginosis, T. vaginalis and C. albicans infection during follow-up were significantly increased and comparable between the groups (p < .001) and decreased in frequency over time (p < .05). The rates of acquisition of bacterial vaginosis among COC users (Nugent score) were 24.6, 18.6 and 15.2% and among LNG-IUS users 20.6, 13.5 and 9.3% at 6 weeks, 6 months and 12 months, respectively (p < .001). Body mass index >25 kg/m2, history of bacterial vaginosis, history of sexually transmitted infection, vaginal douching more than five times per week and coital frequency more than five times per week were strong risk factors for acquisition of bacterial vaginosis during the follow-up period (p < .001). CONCLUSIONS: The use of COCs and LNG-IUS is associated with an increased, comparable risk of acquisition of bacterial vaginosis, T. vaginalis and C. albicans infections, which is greatest during initial use of the method but which improves over time.

Vulvovaginal candidiasis: Etiology, symptomatology and risk factors.

OBJECTIVE: To determine epidemiological, clinical and mycological characteristics of vulvovaginal candidiasis (VVC) in Tunisian population and to evaluate predisposing factors. PATIENTS AND METHODS: In this retrospective study, 2160 vaginal swabs were performed over 2 years (January 2014-December 2015). It was carried out at the laboratory of Parasitology and Mycology, Rabta Hospital in Tunisia. After swab collecting, direct examination and culture on Sabouraud Chloramphenicol and Sabouraud Chloramphenicol Actidione media were implemented to research yeasts. Then identifying of yeast species was through chlamydosporulation test and auxanogram. For each patient, a questionnaire was filled noting age, medical and surgical history, symptoms and risk factors. Statistical analysis of data was performed on SPSS 16 using Khi2 test, P<0.05 was considered significant. RESULTS: Direct examination was positive showed spore and/or pseudohypha in 24.72%. Candida albicans was isolated most frequently (76.61%) followed by Candida glabrata (17.18%). The maximum frequency of Candida-positive cultures was in 25-34 years old age group. Leucorrhea was the most common symptom (72.25%) followed by vulvar prurits (63.23%), dyspareunia (32.25%) and urinary burning (24.92%). Only pregnancy was correlated positively with VVC. CONCLUSION: It appears from our study that VVC is relatively common in Tunisia. His diagnosis results from confrontation of anamnestic, clinical and mycological data. The knowledge of risk factors and their correction would be necessary to prevent the occurrence of VVC, especially in its recurrent form.

Prevalence and Risk Factors for Infections in a Pregnant Adolescent Population.

STUDY OBJECTIVE: Our objective was to identify risk factors associated with maternal infections and placental inflammation in pregnant adolescents attending an urban adolescent maternity clinic. DESIGN: This cross-sectional, descriptive study used survey and medical chart data collected at entry and prospectively across gestation. The prevalence of maternal infections and placental inflammation was determined and potential risk factors were identified. SETTING: Rochester Adolescent Maternal Program (RAMP) in Rochester, NY. PARTICIPANTS: Racially and ethnically diverse pregnant adolescents (n = 158 ≤ 18 y at entry) were recruited. INTERVENTIONS AND MAIN OUTCOME MEASURES: Main outcome measures were diagnosis of an infection or inflammatory condition in relation to demographic, anthropometric, dietary, socioeconomic, and health data. RESULTS: The three most prevalent infections diagnosed in this study population were recto-vaginal colonization of group B Streptococcus (GBS) (38%), bacterial vaginosis (BV) (40%) and candida (42%). African-American teens (AOR = 4.6; 95% CI: 1.74-13.02) and those with higher pre-pregnancy BMI (ppBMI; AOR = 1.2; 95% CI: 1.04-1.31) were more likely to test positive for BV across gestation. Older maternal age decreased the likelihood of positive tests for trichomoniasis (OR = 0.51; 95% CI: 0.26-0.92) and gonorrhea (OR = 0.38; 95% CI: 0.16-0.82). Higher mean dietary vitamin D intake (mcg/d) was associated with a lower likelihood of testing positive for recto-vaginal GBS (OR = 0.87; 95% CI: 0.77-0.98). CONCLUSION: Addressing modifiable risk factors associated with dietary intake and pre-pregnancy weight may help reduce health disparities among pregnant minority adolescents. Additionally, targeted sexual health education may greatly benefit younger female adolescents.

Impact of Obesity on Cesarean Delivery Outcomes.

BACKGROUND: The rate of cesarean delivery has increased over the last 2 decades. Obesity is a risk factor for complications during pregnancy and cesarean procedures. The objective of this study was to evaluate cesarean delivery outcomes in patients with vs without obesity, and determine the impact of obesity on complications. METHODS: The medical records of patients who underwent a cesarean delivery from 2010 to 2014 were reviewed. Patients were grouped by body mass index (BMI) into obese (≥30kg/m²) and non-obese (<30kg/m²) cohorts for comparison. RESULTS: Nine hundred seventy-one patients were included; 432 whom had obesity, and 539 did not have obesity. The rate of gestational diabetes was increased among patients with vs without obesity (15.3% vs 5.8%; P<0.001). Obesity was associated with an increased incidence of surgical site infections (8.1% vs 2.4%; P<0.001), yeast infection (2.8% vs 0.2%; P<0.001), and seroma (2.8% vs 0.4%; P=0.002). Obesity was an independent risk factor for surgical site infections, regardless of wound closure technique (adjusted odds ratio=3.24, 95% CI, 1.66-6.32; P<0.001). CONCLUSIONS: Obesity is a risk factor for wound infections after a cesarean delivery. As obesity rates increase, it is important to be aware of these risks after performing a cesarean delivery.

Highlights Regarding Host Predisposing Factors to Recurrent Vulvovaginal Candidiasis: Chronic Stress and Reduced Antioxidant Capacity.

We studied host factors that could predispose women to develop recurrent vulvovaginal candidiasis (RVVC), including glycemia, insulin resistance, chronic stress, antioxidant capacity, overall immune status, local inflammation and vaginal microbiota. The presence of yeasts in vaginal culture was screened in 277 women, with or without signs and symptoms of VVC and RVVC. The presence of an inflammatory process and microbiota were analyzed through vaginal bacterioscopy and cervical-vaginal cytology, respectively. Fasting-blood samples were collected by standard venipuncture for biochemical analyses. Flow cytometry was employed to obtain the T helper/T cytotoxic lymphocyte ratio, and insulin resistance was assessed by the HOMA index (HI). Yeasts were isolated from 71 (26%) women: 23 (32.4%) with a positive culture but without symptoms (COL), 22 (31%) in an acute episode (VVC), and 26 (36.6%) with RVVC. C. albicans was the main yeast isolated in all clinical profiles. The control group (negative culture) comprised 206 women. Diabetes mellitus and insulin resistance were more associated with the positive-culture groups (COL, VVC and RVVC) than with negative ones. The RVVC group showed lower mean levels of cortisol than the control group and lower antioxidant capacity than all other groups. The T Helper/T cytotoxic lymphocyte ratio was similar in all groups. The RVVC group showed a similar level of vaginal inflammation to the control group, and lower than in the COL and VVC groups. Only the CVV group showed a reduction in vaginal lactobacillus microbiota. Our data suggest that both chronic stress (decreased early-morning cortisol levels) and reduced antioxidant capacity can be host predisposing factors to RVVC.

Treatment of vulvovaginal candidiasis: a review of the literature.

Vulvovaginal candidiasis (VVC) affects around three-quarters of all women during their reproductive age, although the exact incidence of VVC is difficult to determine because many patients are self-treated. The infections are divided into complicated and uncomplicated. Uncomplicated VVC is most effectively treated with local azoles. Oral treatment with a single dose of fluconazole is also effective for treating uncomplicated VVC. Treatment of complicated VVC is prolonged and most commonly consists of multiple doses of oral fluconazole or at least 1 week of local azoles. The role of probiotics in treating VVC is still disputed. This article presents a review of the literature on the various treatment options for VVC. Treatment for the most common pathogens that cause complicated VVC is also discussed.
