Resistant C. albicans implicated in recurrent vulvovaginal candidiasis (RVVC) among women in a tertiary healthcare facility in Kumasi, Ghana.

BACKGROUND: Vulvovaginal candidiasis is a common fungal infection that affects the female lower genital tract. This study determined the major risk factors associated with vulvovaginal infection (VVI) in the Ashanti region of Ghana and also determined the antifungal resistance patterns of Candida albicans isolates to some antifungals. METHODS: Three hundred and fifty (350) high vaginal swab (HVS) samples were collected from women who presented with signs and symptoms of VVI. A structured questionnaire was administered to one hundred and seventy-two (172) of the women. HVS samples were cultured on Sabouraud dextrose agar with 2% chloramphenicol. The polymerase chain reaction was employed to confirm C. albicans. Antifungal susceptibility testing was performed and the susceptibility of C. albicans isolates to fluconazole, clotrimazole, amphotericin B, nystatin, miconazole and 5-flurocytosine were assessed. RESULTS: Vaginal infection was most prevalent amongst females in their reproductive age (21 to 30 years; 63.0%). The study found a significant association between vaginal infections and some risk factors such as sexual practices (p < 0.001), antibiotic misuse (p < 0.05), poor personal hygiene (p < 0.005) and birth control methods (p < 0.049). Out of the 350 HVS samples collected, 112 yielded yeast cells with 65 (58%) identified as C. albicans. The C. albicans isolates were resistant to 5' flucytosine (100%), fluconazole (70%), voriconazole (69.2%), miconazole (58.5%) and nystatin (49.2%). C. albicans isolates were more susceptible to amphotericin B (53.8%) and clotrimazole (45.1%), although an appreciable number of isolates showed resistance (46.1% and 52.3%, respectively). CONCLUSION: There should be nationwide education on all associated risk factors of VVI. Also, use of the various antifungal agents in vaginal candidiasis should proceed after antifungal susceptibility testing to ensure efficacious use of these agents.

Patients with recurrent vulvovaginal candidiasis exhibit a decrease in both the fungicidal activity of neutrophils and the proliferation of peripheral blood mononuclear cells.

BACKGROUND: Recurrent vulvovaginal candidiasis (RVVC) is an important and underestimated fungal infection. OBJECTIVE: We aimed to determine the fungicidal and proliferative capacities of neutrophils and peripheral blood mononuclear cells (PBMCs), respectively and the clinical and microbiological characteristics of a cohort of Colombian patients diagnosed with RVVC. METHODS: A cross-sectional study was conducted. A total of 66 women were included (40 diagnosed with RVVC and 26 healthy women [HW]). Demographic and clinical data were recorded. Vaginal fluid samples were obtained for isolation, identification and antifungal susceptibility testing of Candida species using selective culture media and the Vitek 2.0® system. Blood samples were also obtained to evaluate cell subpopulations; furthermore, neutrophils and PBMCs were isolated to determine their fungicidal and proliferative capacities, respectively. RESULTS: The median age was 29 (IQR: 34-23) for RVVC and 24 (IQR: 30-23) for HW. Only two species of the genus Candida were identified: Candida albicans (92.5%) and Candida lusitaniae (7.5%). Resistance to fluconazole, voriconazole, flucytosine and amphotericin B was observed on six C. albicans isolates and one C. lusitaniae isolate. Only the family history of vulvovaginal candidiasis was associated with RVVC occurrence. The RVVC group exhibited a significantly higher number of neutrophils but with lower fungicidal activity in comparison to HW; likewise, PBMCs from RVVC patients presented a lower proliferation index when stimulated with C. albicans. CONCLUSION: Contrary to what has been reported worldwide, in Colombian patients with RVVC, C. albicans was the main isolated species without increased antifungal resistance. The diminished fungicidal and proliferative capacities of neutrophils and PBMCs, respectively, could suggest a possible alteration in the innate and adaptive immune responses.

Oteseconazole for the Treatment of Recurrent Vulvovaginal Candidiasis: A Drug Review.

OBJECTIVE: The objective of the study is to describe and analyze the pharmacodynamics and pharmacokinetics of oteseconazole as well as the clinical evidence supporting the efficacy of oteseconazole in treating recurrent vulvovaginal candidiasis (RVVC). DATA SOURCES: A literature search was conducted using MEDLINE and EMBASE databases (2015-June 2023). Search terms included "oteseconazole" OR "VT-1161" or "VIVJOA" AND "RVVC" or "recurrent vulvovaginal candidiasis" or "vulvovaginal candidiasis." Conference abstracts, bibliographies, clinical trials, and drug monographs were included for review. STUDY SELECTION AND DATA EXTRACTION: Relevant studies in English and clinical trials conducted in humans were reviewed. DATA SYNTHESIS: Oteseconazole is approved for the treatment of RVVC. In 2 identical phase III studies, oteseconazole was superior to placebo through 48 weeks for preventing recurrence of RVVC (6.7% vs 42.8%, P < 0.001 and 3.9% vs 39.4%, P < 0.001). In the only phase III trial comparing oteseconazole against active drug, oteseconazole was well tolerated and exhibited noninferiority to fluconazole in acute treatment and superiority to placebo for prevention maintenance through 50 weeks (5.1% vs 42.2%, P < 0.001). RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING AGENTS: This review describes the use of oteseconazole for the treatment of RVVC as compared with fluconazole. Oteseconazole is an effective treatment option for common pathogens causing vulvovaginal candidiasis, including Candida and fluconazole-resistant Candida. CONCLUSIONS: Oteseconazole is an effective and safe treatment option for the management of RVVC though current research lacks comparison with established maintenance regimens. Additional research is needed to ascertain the placement of oteseconazole in the treatment of RVVC.

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.

An Exaggerated Monocyte-Derived Cytokine Response to Candida Hyphae in Patients With Recurrent Vulvovaginal Candidiasis.

BACKGROUND: Recurrent vulvovaginal candidiasis (RVVC) affects up to 8% of women. The immunopathogenesis is poorly understood but it has been suggested that RVVC might be due to dysregulated innate immune response. The aim of this study was to compare cytokine profiles in stimulated primary mononuclear cells (PBMCs) from RVVC and healthy individuals. METHODS: PBMCs isolated from RVVC patients (n = 24) and healthy volunteers (n = 30) were stimulated with unspecific and pathogen-specific antigens. Cytokine production was assessed after 24 hours, 48 hours, and 7 days using ELISA. RESULTS: No significant differences in cytokine production were found in T helper 1 (Th1), Th2, and Th17 immunity in response to both unspecific and pathogen-specific stimulations. Tumor necrosis factor-α (TNF-α) production in response to C. albicans hyphae was significantly higher in patients than controls and within the patient group, a significant positive correlation was found between interleukin-1ß (IL-1ß) and both TNF-α and IL-6. Both IL-1ß/IL-1Ra and TNF-α/IL-10 ratios in Candida hyphae-stimulated PBMCs were significantly higher in patients than controls. CONCLUSIONS: Women affected by RVVC showed increased monocytes-derived cytokine production, which might contribute to an exaggerated vaginal immune response to Candida hyphae. RVVC patients show no defective Th-dependent adaptive immune response upon Candida stimulation.

Phase 3 study evaluating the safety and efficacy of oteseconazole in the treatment of recurrent vulvovaginal candidiasis and acute vulvovaginal candidiasis infections.

BACKGROUND: Recurrent vulvovaginal candidiasis affects nearly 138 million women globally each year. In the United States, fluconazole is considered the standard of care for acute vulvovaginal candidiasis, but until recently there was no US Food and Drug Administration-approved drug for the treatment of recurrent vulvovaginal candidiasis. Oteseconazole is a novel oral selective inhibitor of fungal lanosterol demethylase (sterol 14α-demethylase cytochrome P450, an enzyme required for fungal growth) approved for the treatment of recurrent vulvovaginal candidiasis. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of oral oteseconazole (VT-1161) in the prevention of recurrent culture-verified acute vulvovaginal candidiasis episodes through 50 weeks in participants with recurrent vulvovaginal candidiasis and to compare the efficacy of oteseconazole and fluconazole in the treatment of the presenting acute vulvovaginal candidiasis episode. STUDY DESIGN: Women and postmenarcheal girls aged ≥12 years with a history of recurrent vulvovaginal candidiasis (N=219) were enrolled at 38 US sites. Eligible participants presenting with an active vulvovaginal candidiasis infection entered an induction phase in which they were randomly assigned 2:1 to receive 600 mg oral oteseconazole on day 1 and 450 mg on day 2, with matching placebo capsules, or to 3 sequential 150-mg oral doses (once every 72 hours) of fluconazole, with matching placebo capsules. Following the 2-week induction phase, the 185 participants with resolved acute vulvovaginal candidiasis infection (a clinical signs and symptoms score of <3) entered the maintenance phase and received 150 mg of oteseconazole or placebo weekly for 11 weeks. Participants were observed for an additional 37 weeks. RESULTS: In the induction phase, oteseconazole was noninferior to fluconazole in the proportion of participants in the intent-to-treat population with resolved acute vulvovaginal candidiasis infection at the week 2 (day 14) test-of-cure visit, with 93.2% of participants on oteseconazole vs 95.8% on fluconazole achieving resolution. In the maintenance phase, oteseconazole was superior to placebo in the proportion of participants in the intent-to-treat population with ≥1 culture-verified acute vulvovaginal candidiasis episode through 50 weeks, 5.1% compared with 42.2%, respectively (P<.001). Overall, treatment-emergent adverse event rates were similar in both groups: 54% for participants who received oteseconazole in the induction and maintenance phases vs 64% for participants who received fluconazole in the induction phase and placebo in the maintenance phase. Most treatment-emergent adverse events in each group were mild or moderate, with 3.4% of treatment-emergent adverse events graded as severe or higher in the OTESECONAZOLE/oteseconazole group vs 4.2% in FLUCONAZOLE/placebo group. CONCLUSION: In participants with recurrent vulvovaginal candidiasis, oteseconazole was safe and efficacious in the treatment and prevention of recurrent acute vulvovaginal candidiasis episodes and was noninferior to vulvovaginal candidiasis standard-of-care fluconazole in the treatment of the presenting acute vulvovaginal candidiasis infection.

Virulence is one of the mechanisms of vulvovaginal candidiasis recurrence, rather than drug resistance.

To explore the mechanism of vulvovaginal candidiasis (VVC) recurrence. A total of 127 strains of Candida albicans (C. albicans) were collected, including 58, 40, and 29 strains from the recurrent vulvovaginal candidiasis (RVVC), VVC, and asymptomatic carrier (AC), respectively. The strains' virulence such as in vivo hypha formation rate, germ tube formation rate, biofilm formation ability, and sensitivity to five common antifungals were detected. The in vivo hypha formation rates of C. albicans from the RVVC (55.2%) and VVC (40.0%) were significantly higher than that from the AC (0%) (P < .001). The median germ tube formation rate of the RVVC was 88.2%, which was higher than that of the VVC and AC (59.9% and 65.6%), respectively (P < .001). The median absorbance of the biofilm formation test for strains in the RVVC was 0.380, considerably higher than that in the VVC and AC (0.246 and 0.254) (P < .001). The drug sensitivity rate of the strains to 5-fluorocytosine and itraconazole and the ratio of strains sensitive to all the five antifungals in the VVC group were lower than those in the RVVC and AC groups. In conclusion, the virulence of strains from the RVVC is stronger than that of strains from the VVC and AC, the antifungal resistance rate of strains from the RVVC group is lower than that of strains from the VVC group. So, it is suitable to argue that the strains' virulence is one of the mechanisms for the relapse of RVVC, rather than its antifungal resistance.

The virulence of strains from recurrent vulvovaginal candidiasis (RVVC) is stronger than that from vulvovaginal candidiasis (VVC) and asymptomatic carrier (AC), but the drug resistance rates are opposite. Virulence is one of the mechanisms of the relapse of RVVC, rather than drug resistance.

Lived experience of medical management in recurrent vulvovaginal candidiasis: a qualitative study of an uncertain journey.

BACKGROUND: Recurrent vulvovaginal candidiasis (RVVC) is experienced by up to 10% of pre-menopausal women globally, yet there is limited research exploring the perspective of women living with this challenging condition. METHODS: Semi-structured interviews with Australian women experiencing RVVC were conducted between April-July 2021. Interviews were transcribed verbatim, and qualitative interpretative phenomenological analysis (IPA) was conducted. RESULTS: Ten RVVC patients were interviewed. IPA revealed an uncertain journey living with RVVC for all participants ranging from initial symptoms and difficulties in obtaining a diagnosis, the trial and error of symptom management, to the overall debilitating impact of living with a personal and intimate health condition. Four key themes were identified: Theme 1 outlined challenges and delays in diagnosis and clinically appropriate management. Theme 2 found that health care professional (HCP) knowledge limitations impacted RVVC management. Theme 3 illustrated the consequences of a lack of HCP support leading to self-referral and self-education. Theme 4 details the significant emotional and psycho-social repercussions of RVVC. CONCLUSIONS: This debilitating, life-long disease has a prolonged effect on women both physically and psychologically. Living with RVVC seems an uncertain journey that, to a large degree, women feel they must navigate alone. While resilience and self-empowerment were noted, better support through evidence-based treatment options, educated and evidence-informed HCPs and a sympathetic social support network is needed to decrease the disease burden. Future clinical management guidelines and patient support need to consider the findings of this study.

Analysis of pathogenic factors of Candida albicans and the effect of vaginal immunization on recurrent vulvovaginal candidiasis in mice.

BACKGROUND: The role of fungal pathogenic factors and the immune response of the vaginal epithelium in vulvovaginal candidiasis (VVC) and recurrent vulvovaginal candidiasis (RVVC) are still unclear. Our study wants to clarify whether there are differences in pathogenic factors between VVC and RVVC strains, confirm the roles of pathogenic factors in the pathogenesis of RVVC, and analyze the influence of pathogenic factors on vaginal host immunity. METHODS: VVC- and RVVC-causing Candida albicans strains were genotyped with 25S rDNA. Drug susceptibility assays using a modified alamarBlue broth microdilution method were carried out. Milk culture medium and egg yolk culture medium were used to measure the secreted aspartate protease (Sap) and phospholipase (Plb) activity of the samples. We used C. albicans with different Sap activity levels to induce RVVC in mice and measured interleukin 4 (IL4), interleukin 8 (IL8), and interleukin 17 (IL17) in vaginal lavage fluid at different stages of RVVC infection. RESULTS: There were no significant differences between VVC and RVVC fungi except that the Sap activity was lower for RVVC-causing C. albicans than for VVC-causing C. albicans. C. albicans with both strong Sap and weak Sap induced RVVC in mice. C. albicans with strong Sap had a reduced RVVC infection rate. In addition, C. albicans with strong Sap stimulated the vaginal epithelium to secrete more IL4, IL8, and IL17. CONCLUSION: Compared with that of VVC-causing C. albicans, the Sap activity of RVVC-causing C. albicans was lower. C. albicans with strong Sap was less capable of causing repeated vaginal infections than that with weak Sap and stimulated the vaginal epithelium to produce more cytokines.

Is mannose-binding lectin serum concentration a reliable predictor for recurrent vulvovaginal candidiasis?

Recurrent vulvovaginal candidiasis (RVVC) is a common opportunistic, mucosal fungal infection, predominantly caused by the fungus Candida albicans. Mannose-binding lectin (MBL) is an acute-phase protein that plays a key role in the innate immunity defence against infectious disease. This study was conducted to evaluate the relationship between the MBL serum level and the relative expression of MBL mRNA in RVVC using real-time PCR for the first time. The case-control study included 40 female participants suffering from RVVC and 40 healthy individuals. The MBL serum level was measured using a commercial ELISA kit. The relative mRNA expression of the MBL gene was quantified using real-time PCR. Data analysis was carried out by spss software. The MBL concentration was significantly higher in the participants suffering from RVVC compared to the control group (0.330 ng/mL vs 0.253 ng/mL). The prognostic value (P < .001) for RVVC diagnosis has been calculated. Quantitative RT-PCR results from 35 samples showed a low to significant values for mRNA levels corresponding to MBL gene expression (1-352 folds) (P < .001). The results of this study suggest that MBL plays a main role in the innate immunity and it is also affected by environmental factors and other genetic variations. Therefore, the MBL gene expression profile does not reflect precise phenotypic levels in the serum.

Influence of recurrent vulvovaginal candidiasis on quality of life issues.

PURPOSE: More than 370 million women will experience recurrent vulvovaginal candidiasis (RVVC) during their lifetime. However, RVVC is often trivialized as clinically insignificant and not worthy of research funding. We evaluated the influence of RVVC on the quality of life in affected women. METHODS: The validated World Health Organization Quality of Life Abbreviated Assessment (WHOQOL-Bref) questionnaire was administered to 100 women with RVVC and to 101 epidemiologically matched women with no history of vulvovaginal candidiasis. RVVC was defined as at least four episodes of clinical and culture-positive vaginal candidiasis within a 1 year period. Data were analyzed by Chi square, Student t test and analysis of variance. Internal consistency of responses to questions was evaluated by Cronbach alpha. RESULTS: The Cronbach alpha coefficient was > 0.80 for responses to generalized questions and > 0.65 for answers to more specific questions, indicating substantial internal consistency. Perception of quality of life and satisfaction with their health was greatly reduced in the RVVC group (p < 0.001). Diminished responses to physical and psychological well-being were also reported by women with RVVC (p < 0.001). Various aspects of social relations including sexual activity were similarly reduced (p < 0.001) as were satisfaction with issues such as home environment, financial resources and employment (p < 0.001). CONCLUSION: RVVC affects multiple aspects of a woman's well-being. Women with this condition deserve serious attention from clinicians and research into susceptibility, prevention and treatment of this infection deserves much greater emphasis.

Abnormal vaginal microbioma is associated with severity of localized provoked vulvodynia. Role of aerobic vaginitis and Candida in the pathogenesis of vulvodynia.

Localized provoked vulvodynia (LPV) causes introital dyspareunia in up to 14% of premenopausal women. Vaginal infections like candidosis may play a initiating role. The aim of this study was to test a possible association of vaginal microbiota alternations such as Candida vaginitis (CV), aerobic vaginitis (AV) and bacterial vaginosis (BV) with severity of vulvodynia and painful intercourse. In an observational study, Q-tip touch test (score 1 (no pain) to 10 (worst possible pain)) was performed on seven vestibular locations in 231 LPV patients presenting in the Vulvovaginal Disease Clinics in Tienen, Leuven and Antwerp, Belgium. Severity of pain upon attempting sexual intercourse was recorded in a similar scale. Both scales were compared to results from fresh wet mount phase contrast microscopy on vaginal fluid smears tested for abnormal vaginal flora (AVF), BV, AV and CV according the standardized microscopy method (Femicare). Fisher's exact test was used. Average age was 31.3 ± 11.6 years, and 58.8% (n = 132) had secondary vestibulodynia. There was an inverse relation between the presence of Candida in the vaginal smears and pain score (p = 0.03). There was no relation of pain score, nor Q-tip score with BV. LPV patients with Q-tip score above 7 at 5 and/or 7 o'clock or at 1 and/or 11 o'clock had more often AV than women with lower pain scores (30 vs 14.5%, p = 0.01, and 39 vs 14.7%, p < 0.005, respectively). Detailed study of the vaginal microflora in patients demonstrates that the most severe patients suffer more from AV and less from Candida. These abnormalities need to be actively looked for and corrected before considering surgery or other therapies.

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.

A comparative investigation of azole susceptibility in Candida isolates from vulvovaginal candidiasis and recurrent vulvovaginal candidiasis patients in Ghana.

Vulvovaginal candidiasis (VVC) and recurrent vulvovaginal candidiasis (RVVC) affect millions of women and are typically treated with azoles. We know little about azole susceptibility of Candida species from VVC versus RVVC patients, and nothing about African isolates. We have investigated the susceptibility of Candida isolates from Ghana to fluconazole, itraconazole and/or voriconazole. The percentage of Candida albicans isolates showing susceptibility was significantly lower in RVVC than VVC patients. Isolates of Candida parapsilosis and Candida tropicalis showed a similar trend. For Candida glabrata there was no observed difference. The data indicate a decreased susceptibility in selected Candida species from RVVC patients.

Elevated nitric oxide in recurrent vulvovaginal candidiasis - association with clinical findings.

INTRODUCTION: Recurrent vulvovaginal candidiasis is defined as having three to four episodes per year and causes substantial suffering. Little is known about the mechanisms leading to relapses in otherwise healthy women. Nitric oxide is part of the nonspecific host defense and is increased during inflammation. Nitric oxide levels were measured and the expression of inducible nitric oxide synthase was analyzed in the vagina during an acute episode of recurrent vulvovaginal candidiasis and after treatment with fluconazole. MATERIAL AND METHODS: Twenty-eight women with symptoms of recurrent vulvovaginal candidiasis were enrolled together with 31 healthy controls. Nitric oxide was measured with an air-filled 25-mL silicon catheter balloon incubated in the vagina for five minutes and then analyzed by chemiluminescence technique. Vaginal biopsies were analyzed for the expression of inducible nitric oxide synthase. Symptoms and clinical findings were surveyed using a scoring system. The measurements and biopsies were repeated in patients after six weeks of fluconazole treatment. RESULTS: Nitric oxide levels were increased during acute infection (median 352 ppb) compared with controls (median 6 ppb), p < 0.0001. The levels decreased after treatment (median 18 ppb) but were still higher than in controls. Increased expression of inducible nitric oxide synthase was observed in the epithelial basal layer in patients before and after treatment compared with controls. Before treatment, there were positive correlations between nitric oxide and symptom (rs  = 0.644) and examination scores (rs  = 0.677), p < 0.001. CONCLUSIONS: Nitric oxide is significantly elevated in patients with recurrent vulvovaginal candidiasis during acute episodes of infection and decreases after antifungal treatment. The results illustrate the pronounced inflammatory response in recurrent vulvovaginal candidiasis correlating to symptoms of pain and discomfort.

Candida vulvovaginitis: A store with a buttery and a show window.

Although being an utterly frequent, non-mortal, yet distressing disease, and despite good knowledge of the pathogenesis and the availability of specific and safe treatment, vulvovaginal Candida (VVC) infection remains one of the most enigmatic problems for both physicians and patients. Good treatment requires a proper diagnosis. Too many caregivers (and patients treating themselves) react too simple-minded on the symptoms of VVC and treat VVC where they see it on the vulva. In this opinion paper, we plea for a thorough examination of women with VVC, especially in those women who suffer from recurrent disease since a long time, sometimes decades, which necessitates intensive examination of the vaginal flora, as this is invariably the reservoir for relapses and recurrent vulvitis. Examination of such complicated cases requires experienced clinical judgement, expertise bedside phase contrast microscopy of fresh vaginal fluid, classical cultures on Sabouroud medium and, if still unresolved, repetitive cultures taken by the patient herself at moments of symptoms, and/or nuclear acid amplification techniques to detect Candida genes in the vaginal fluid. Even if only vulvitis is evident, thorough expert examination of vaginal fluid is obligatory to diagnose VVC.

Comparison of two long-term gestagen regimens in the management of recurrent vulvovaginal candidiasis: A pilot study.

Vulvovaginal candidiasis (VVC) is a hormonal-dependent infection but in contrast to sporadic VVC, therapy of recurrent vulvovaginal candidiasis (RVVC) is still unsolved. Long-term administration of medroxyprogesterone acetate was evaluated for the management of RVVC. Overall, 20 patients were treated with Depo-Provera; 14 patients were treated with Provera. Gestagen therapy was evaluated based on visual analogue scale (VAS), the frequency of attacks, the side effects of gestagens and the consumption of antifungals. There was a reduced symptomatology in both of the groups and substantial reduction in antifungal drug consumption during the second year of gestagen use. Twenty-four patients (70.6%) evaluated their condition regarding the vulvovaginal area as improvement (VAS decrease of 3-5 points). Five patients (14.7%) mentioned minimal or no improvement. Further, a number of antifungal drug-treated episodes dropped dramatically during the study period. Both regimes provided similar results, but five patients from the Depo-Provera group had to withdraw from gestagen therapy. Gestagen supplementation ameliorated the quality of life for the majority of patients with RVVC and suggested a potential role in the management of this syndrome, even if beneficial effect was evident after longer application, and some patients met with side effects that led to an interruption of therapy.

Non-response to fluconazole maintenance treatment (ReCiDiF regimen) for recurrent vulvovaginal candidosis is not related to impaired glucose metabolism.

Is non-response to maintenance treatment for recurrent vulvovaginal candidosis (RCVV) related to the impaired glucose metabolism? In the ReCiDiF trial, women with RCVV were given a degressive regimen with fluconazole according to their clinical, microscopic and mycologic response. Data obtained from optimal, suboptimal and non-reponding patients were used for secondary analysis of medical history, physical status and family history for potential glucose impairment. Results were presented in means and percentages. Pearson chi-square, Fisher exact, Mann-Whitney U, Kruskal-Wallis and Spearman's correlation coefficient was calculated. P<.05 were interpreted as statistically significant. Sociodemographic characteristics and family and personal history of diabetes were not different between optimal, suboptimal and non-responders. The average HbA1c concentration was 5.1±0.3% in optimal, 5.0±0.4% in sub-optimal, and 5.1±0.3% in non-responding patients (P=1.0). There are no statistical differences between optimal, sub-optimal and non-respondents to treatment in all deciles of HbA1c among patients with recurrent candidosis (P=1.0). There was no difference among groups in fasting glucose concentration, nor after 30 min, 60 min or 120 min during the oral glucose tolerance test (OGTT) (P=.6). Area under the OGTT curve did not differ within groups (P=.8), nor was the deviation from the normal cut-off value any different (P=.8). Glucose concentration in vaginal rinsing fluid showed no correlation with responsiveness to treatment (P=.7). Glucose metabolism, BMI, personal or family history of diabetes are not related to non-response to maintenance treatment with fluconazole for patients with RVVC.

Management of chronic vulvovaginal candidiasis: a long term retrospective study.

BACKGROUND: Chronic vulvovaginal candidiasis (CVVC) is an unremitting condition causally associated with species of Candida. Limited data are available on its management and long-term outcomes. This retrospective study aimed to explore the long-term outcomes of patients who had experienced symptom remission after a course of oral antifungals. METHODS: Retrospective study conducted over 1 year from data obtained from a vulval dermatology outpatient clinic in Sydney, Australia. Data from 208 patients satisfying presumptive or definitive criteria for CVVC who had been successfully treated with oral azole antifungal medication were collected from a database, including drugs, induction and maintenance treatment regimes, results and adverse effects. RESULTS: Altogether 208 patients commenced an induction regime of oral fluconazole 50-100 mg daily for up to 12 weeks. All patients demonstrated a clinical improvement within 12 weeks. Of the 208 patients, subsequently 95% remained on oral fluconazole for maintenance treatment, 3% changed to other antifungals due to adverse effects and 2% ceased treatment. The most common maintenance regime was oral fluconazole 50 mg twice weekly (46%). Of the study cohort 99% remained on treatment with antifungal therapy for symptom suppression with the mean duration of follow up 26.2 months (range, 5 months to 8.5 years). CONCLUSIONS: Long-term symptom remission was possible in this subset of women with CVVC using fluconazole 50-100 mg or itraconazole 50-100 mg. However, most were unable to cease treatment without experiencing relapse. Adverse effects in this cohort were minimal and there were no cases of drug-induced hepatitis.

Health-related quality of life as measured with the Short-Form 36 (SF-36) questionnaire in patients with recurrent vulvovaginal candidiasis.

BACKGROUND: Recurrent vulvovaginal candidiasis (RVVC) has a poor therapeutic outcome and a severe impact on women and their partners, both physically and psychologically. Health-related quality of life (HRQOL) is significantly affected in patients with RVVC; however, little is known about HRQOL in patients with this disease. In this study, we aim to identify the clinical and mycological characteristics of women with RVVC and the effects of RVVC on women's HRQOL. METHODS: We designed this study as a comparative cross-sectional study. The Short-Form Health Survey (SF-36) was used to measure HRQOL in 102 patients with RVVC and 101 women seeking general health care (controls). RVVC was defined as four or more episodes of proven VVC in the previous 12-month period. VVC was defined as vulvar itching, burning, erythema, vaginal discharge, pseudohyphae or blastoconidia on a wet 10 % potassium hydroxide (KOH)-treated vaginal slide and a positive Candida culture. Group comparisons were conducted with independent samples t test. Correlation analysis was performed on the variables. RESULTS: The mean age at first diagnosis of the patients with RVVC was 30.96 years (SD 5.38), and the mean age of the controls was 29.75 years (SD 5.83; p > 0.05). The duration of the patients' complaints varied from 6 months to 10 years, with a mean duration of 22.28 (±21.75) months. The most common complaints were increased vaginal discharge (102 cases, 100 %), itching (97 cases, 95.1 %), dyspareunia (65 cases, 63.7 %), burning (79 cases, 77.5 %) and erythema (25 cases, 24.5 %). C. albicans was the predominant Candida species (86 strains, 84.3 %) in the patients, followed by C. glabrata (12 strains, 11.8 %). C. parapsilosis (1 strain, 0.9 %), C. tropicalis (1 strain, 0.9 %), C. krusei (1 strain, 0.9 %) and C. lusitaniae (1 strain, 0.9 %). The mean SF-36 dimension scores for physical function, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health were significantly lower in the patients with RVVC than in the controls (85.20, 61.39, 77.79, 54.95, 53.17, 67.89, 52.48 and 59.17 vs. 90.20, 80.87, 87.08, 67.38, 59.69, 79.86, 68.01 and 65.38). The physical composite and mental composite scores of the patients with RVVC were 63.06 and 64.87, respectively, which were lower than those of the controls (75.01 and 74.87; p < 0.05). CONCLUSIONS: Nearly all of the patients with RVVC had clinical symptoms. In our sample, RVVC was mainly caused by C. albicans. RVVC has negative effects on women's HRQOL, as indicated by lower physical and mental composite scores among the RVVC group compared with controls.
