Vulvovaginal candidiasis and type 2 diabetes: A nationwide retrospective cohort study.

AIMS: To examine whether vulvovaginal candidiasis (VVC) precedes type 2 diabetes and to quantify the possible time period between VVC and subsequent diabetes. MATERIAL AND METHODS: We conducted a nationwide retrospective primary healthcare study including 1 838 929 women aged 35-65 years in Sweden (2007-2018). Cox regression models were used to examine associations between VVC and type 2 diabetes, while controlling for possible confounders. Propensity-score-weighted analysis was also conducted. RESULTS: The incidence rate of diabetes per 1000 person-years was 3.06 (95% confidence interval [CI] 3.05-3.08) in women without preceding VVC and 4.05 (95% CI 3.86-4.24) in women with preceding VVC. The incidence rate was particularly high in women aged 55 years and older with VVC: 9.56 (95% CI 8.01-11.11). Women with VVC had a hazard ratio (HR) of 1.41 (95% CI 1.28-1.55) for diabetes compared to women without VVC in the multivariable-adjusted model. The corresponding HR was 1.63 (95% CI 1.53-1.74) in propensity-score-weighted analysis. Women with prior VVC also seemed to have a stronger risk of diabetes with older age, particularly after the age of 55 years. The mean (range) time between VVC and subsequent diabetes was 0.57 (0-2) years, depending on the age of the woman. CONCLUSION: We found temporal associations between VVC and diabetes. The findings demonstrate that the presence of VVC may indicate a future diagnosis of diabetes, especially in women aged 55 years and older. This knowledge could be valuable for clinicians when treating women with VVC.

A Feasibility Study Investigating a Topical Preparation as Novel Adjunct Treatment for the Symptomatic Management of Vulvovaginal Skin Conditions.

Objective: The study aimed to investigate the feasibility of a newly available topical gel in improving the symptoms of various vulvovaginal skin conditions (NCT05396261). Methods: Fifty-two women with diagnosed lichen sclerosus, lichen simplex chronicus, or genitourinary syndrome of menopause participated in this prospective single-arm feasibility study. Consented patients applied the product daily internally and externally to the genital area for approximately 6 months (short-term) and optionally up to 2 years (long-term). Outcome measures included patient-rated symptoms, investigator-assessed clinical signs, and visual severity of pathology of these vulvovaginal conditions. Clinical outcomes, patient adherence to the treatment, and adverse events were assessed, and the statistical analysis was split according to short-term and long-term treatment. Results: The majority of patients enrolled in the study suffered from an uncontrolled disease (90.4%). All patients showed significant improvement in all patient-rated symptoms (p < 0.001), overall clinical signs (p < 0.001), and visual severity of pathology (p < 0.001) short-term. These favorable results were maintained from month 6 up to 2 years. Patient compliance was high, and no adverse events were reported with use of the investigational product. Conclusions: This topical medical device could be an effective symptomatic management option for women suffering from various vulvovaginal conditions.

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.

Mechanism of Vaginal Epithelial Cell Pyroptosis Induced by the NLRP3 Inflammasome in Vulvovaginal Candidiasis.

PROBLEM: Vulvovaginal candidiasis (VVC) is a common mucosal fungal infection, and Candida albicans is the main causative agent. The NLRP3 inflammasome plays an important role in VVC, but the underlying mechanism is unknown. METHOD OF STUDY: Vaginal epithelial cells were divided into three groups: control, C. albicans strain SC5314 (wild-type, WT), and WT+ Matt Cooper Compound 950 (MCC950, a specific NLRP3 inhibitor). After human vaginal epithelial cells were pretreated with 1 µmol/L MCC950 for 2 h, C. albicans (MOI = 1) was cocultured with the human vaginal epithelial cells for 12 h. The cell supernatants were collected, LDH was detected, and the IL-1ß and IL-18 levels were determined by ELISA. The expression of the pyroptosis-related proteins NLRP3, Caspase-1 p20 and GSDMD was measured by Western blotting analysis. The protein expression of the pyroptosis-related N-terminus of GSDMD (GSDMD-N) was detected by immunofluorescence. RESULTS: In this study, we showed that the WT C. albicans strain induced pyroptosis in vaginal epithelial cells, as indicated by the LDH and proinflammatory cytokine levels and the upregulated levels of the pyroptosis-related proteins NLRP3, Caspase-1 p20, and GSDMD-N. MCC950 reversed the changes in the expression of these proteins and proinflammatory cytokines in vaginal epithelial cells. CONCLUSION: C. albicans activated the NLRP3 inflammasome to induce vaginal epithelial cell pyroptosis. MCC950 inhibited the NLRP3 inflammasome, reduced vaginal epithelial cell pyroptosis, and decreased the release of inflammatory cytokines.

Ibrexafungerp: A narrative overview.

Ibrexafungerp (IBX) is a new antifungal drug that recently entered the antifungal landscape. It disrupts fungal cell wall synthesis by non-competitive inhibition of the ß-(1,3)-D-glucan (BDG) synthase enzyme. It has demonstrated activity against a range of pathogens including Candida and Aspergillus spp., as well as retaining its activity against azole-resistant and echinocandin-resistant strains. It also exhibits anti-biofilm properties. Pharmacokinetic (PK) studies revealed favorable bioavailability, high protein binding, and extensive tissue distribution with a low potential for CYP-mediated drug interactions. It is characterized by the same mechanism of action of echinocandins with limited cross-resistance with other antifungal agents. Resistance to this drug can arise from mutations in the FKS genes, primarily FKS2 mutations in Nakaseomyces glabrata. In vivo, IBX was found to be effective in murine models of invasive candidiasis (IC) and invasive pulmonary aspergillosis (IPA). It also showed promising results in preventing and treating Pneumocystis jirovecii infections. Clinical trials showed that IBX was effective and non-inferior to fluconazole in treating vulvovaginal candidiasis (VVC), including complicated cases, as well as in preventing its recurrence. These trials positioned it as a Food and Drug Administration (FDA)-approved option for the treatment and prophylaxis of VVC. Trials showed comparable responses to standard-of-care in IC, with favorable preliminary results in C. auris infections in terms of efficacy and tolerability as well as in refractory cases of IC. Mild adverse reactions have been reported including gastrointestinal symptoms. Overall, IBX represents a significant addition to the antifungal armamentarium, with its unique action, spectrum of activity, and encouraging clinical trial results warranting further investigation.

A paradigm shift in understanding vulvovaginal melanoma as a distinct tumor type compared with cutaneous melanoma.

OBJECTIVE: Our goal was to compare molecular and immune profiles of vulvovaginal melanoma (VVM) with cutaneous melanoma (CM) and explore the significance of immune checkpoint inhibitor (ICI) agents on survival. METHODS: Samples from VVM and CM tumors underwent comprehensive molecular and immune profiling. Treatment and survival data were extracted from insurance claims data and OS was calculated from time of ICI treatment to last contact. Statistical significance was determined using chi-square and Wilcoxon rank sum test and adjusted for multiple comparisons. RESULTS: Molecular analysis was performed on 142 VVM and 3823 CM tumors. VVM demonstrated significantly (q < 0·01) less frequent BRAF and more frequent KIT, ATRX, and SF3B1 mutations. Alterations in pathways involving DNA damage and mRNA splicing were more common in VVM, while alterations in cell cycle and chromatin remodeling were less common. Immunogenicity of VVM was lower than CM, with an absence of high TMB (0% vs 46.9%) and lower PD-L1 positivity (18·0% vs 29·5%). Median immune checkpoint gene expression was lower in VVM, as were cell fractions for type I macrophages and CD8+ T-cells(q < 0·01). Myeloid dendritic cells were increased in VVM(q < 0·01). Median OS was shorter for VVM than for CM patients treated with ICIs (17·6 versus 37·9 months, HR:1·65 (95% CI 1·02-2·67) p = 0·04). CONCLUSIONS: VVM has a distinct molecular and immune profile compared to CM, which may contribute to the worse survival in VVM compared to CM patients treated with ICI therapy. Though ICIs have been a mainstay of treatment in recent years, our findings suggest that new therapeutic strategies are needed.

Ospemifene for Genitourinary Syndrome of Menopause: Patient Selection.

Vulvar vaginal atrophy is a common condition affecting postmenopausal women, significantly impacting their quality of life. Fortunately, various treatment options are available, ranging from hormonal to non-hormonal therapies. Ospemifene has emerged as a promising non-hormonal alternative for managing vulvar vaginal atrophy. Its targeted approach, unique mechanism of action, favorable safety profile particularly for breast tissue, and efficacy make it a valuable option for women seeking relief from symptoms such as vaginal pain, dryness and dyspareunia and cannot receive estrogen supplementations. This is particularly the case for breast cancer survivors or women with a significant family history of estrogen-dependent cancers. Hence, tailored treatment plans, considering individual preferences and health circumstances, are essential in optimizing outcomes and improving the overall well-being of affected individuals.

Stable Ozonides plus Vitamin E Acetate (Ozoile) for Treatment of Genitourinary Syndrome.

Background and Objectives: Genitourinary syndrome, previously defined as vulvovaginal atrophy, manifests with signs and symptoms deriving from estrogen diminution in the female genitourinary tract. Stable ozonides are derivatives of artemisinin found to be stable against strong basic and acidic conditions. Vitamin E is an important antioxidant diminishing the output of reactive oxygen species in the oxidation of fats and the emanation of free radicals, reducing cellular injury and aging. The primary aim of the present study was to assess the positive effects of an ozonide plus a vitamin E acetate-based compound (Ozoile) on genitourinary syndrome symptom relief after a maximum of 20 days of treatment. Materials and Methods: The inclusion criteria for patients' enrollment were women of child-bearing age or in menopause reporting genitourinary syndrome's related symptoms, such as pain, burning, a bad smell, dyspareunia, dryness, itching, bleeding, and nervousness. The exclusion criteria were Sjogren's syndrome and patients administered retinoic acid, an agent that causes mucosal dryness. Participants completed a questionnaire before and after 20 days of treatment. Results: The incidence of pain decreased from 16.7% to 11.8% (p-value < 0.0001). In addition, the mean symptom intensity decreased from 2.10 to 0.87 (p-value < 0.0001). Dryness was the most frequent pre-treatment symptom and decreased from 85.5% to 53.8% (p-value < 0.0001) (mean: 2.21 vs. 0.90; p-value < 0.0001). Conclusions: Ozoile was effective in reducing most gynecologic symptoms related to genitourinary syndrome. However, further studies are needed to compare its effect with other standards of care.

Tumour necrosis is a valuable histopathological prognostic parameter in melanomas of the vulva and vagina.

Vulvar and vaginal melanomas (VVMs) are rare and aggressive malignancies with limited prognostic models available and there is no standard reporting protocol. VVMs were selected from six tertiary Canadian hospitals from 2000-2021, resected from patients aged ≥18 years, with 6 months or longer follow-up data, and confirmation of melanocytic differentiation by at least two immunohistochemical markers. Cases were reviewed by pathologists to identify histological biomarkers. Survival outcomes were tested with Kaplan-Meier log-rank, univariate Cox, and multivariate Cox regression. There were 79 VVMs with median follow-up at 26 months. Univariate analysis revealed that tumour necrosis, tumour ulceration, positive lymph nodes, and metastasis at diagnosis were significantly associated with disease-specific mortality, progression, and metastasis. Multivariate analysis identified tumour necrosis as an independent prognostic factor for disease-specific mortality (HR 4.803, 95% CI 1.954-11.803, p<0.001), progression (HR 2.676, 95% CI 1.403-5.102, p=0.003), and time-to-metastasis for non-metastatic patients at diagnosis (HR 3.761, 95%CI 1.678-8.431, p=0.001). Kaplan-Meier survival analyses demonstrated that tumour necrosis was a poor prognostic factor for disease-specific, progression-free, and metastasis-free survival (p<0.001 for all comparisons). Vaginal melanomas displayed decreased survival compared to vulvar or clitoral melanomas. This study identifies tumour necrosis as an independent prognostic factor for VVMs. Vaginal melanomas specifically showed worse survival outcomes compared to vulvar or clitoral melanomas, consistent with previously reported findings in the literature, emphasising the importance of differentiating between these primary tumour epicentres for prognostication and treatment planning in the care of genital melanoma patients.

Comparative performance of vulvovaginal swab sampling versus endocervical sampling for the detection of Chlamydia, Gonorrhea, Mycoplasma genitalium, and Trichomoniasis: a cross-sectional study in Spain.

INTRODUCTION: The global increase in sexual transmitted infections (STI) makes it necessary to seek public health strategies that facilitate rapid and minimally invasive diagnosis. The objective was to evaluate the concordance between vaginal and endocervical samples for STI diagnosis. MATERIALS AND METHODS: A retrospective cross-sectional study was carried out on vaginal and endocervical samples from women attended in our reference area with symptoms suggestive of vulvovaginitis or for STI screening during the study period. RESULTS: A total of 130 paired samples were analyzed; fifty-seven and 59 samples were positive for vaginal and endocervical specimens (Kappa index of 0.969 (Standard error = 0.022). The sensitivity of the vaginal samples was 96.5% (IC95%: 87.2-99.4), with a specificity of 100% (IC95%: 93.0-100). DISCUSSION: The introduction of STI screening in vaginal samples in our environment can facilitate rapid and effective diagnosis and allow early treatment of STI. Additionally, it facilitates sample collection and diagnosis in the community setting, essential for optimal screening.

Mapping the Burden of Fungal Diseases in the United Arab Emirates.

The United Arab Emirates has very little data on the incidence or prevalence of fungal diseases. Using total and underlying disease risk populations and likely affected proportions, we have modelled the burden of fungal disease for the first time. The most prevalent serious fungal conditions are recurrent vulvovaginitis (~190,000 affected) and fungal asthma (~34,000 affected). Given the UAE's low prevalence of HIV, we estimate an at-risk population of 204 with respect to serious fungal infections with cryptococcal meningitis estimated at 2 cases annually, 15 cases of Pneumocystis pneumonia (PCP) annually, and 20 cases of esophageal candidiasis in the HIV population. PCP incidence in non-HIV patients is estimated at 150 cases annually. Likewise, with the same low prevalence of tuberculosis in the country, we estimate a total chronic pulmonary aspergillosis prevalence of 1002 cases. The estimated annual incidence of invasive aspergillosis is 505 patients, based on local data on rates of malignancy, solid organ transplantation, and chronic obstructive pulmonary disease (5.9 per 100,000). Based on the 2022 annual report of the UAE's national surveillance database, candidaemia annual incidence is 1090 (11.8/100,000), of which 49.2% occurs in intensive care. Fungal diseases affect ~228,695 (2.46%) of the population in the UAE.

Treatment of vaginitis caused by non-albicans Candida species.

INTRODUCTION: In the face of increased frequency of non-albicans Candida vulvovaginitis (VVC) reported worldwide, there is a paucity of effective oral and topical antifungal drugs available. Drug selection is further handicapped by an absence of data of clinical efficacy of available antifungal drugs for these infections. AREAS COVERED: In this review, attention is directed at the cause of drug shortage as well as increased frequency of non-albicans Candida (NAC) vulvovaginitis. There is widespread recognition of reduced in vitro azole drug susceptibility in NAC species. Moreover, antifungal susceptibility tests have not been standardized or validated for NAC isolates, hence clinicians rely on an element of empiricism especially given the absence of randomized controlled comparative studies targeting NAC species. Clinical spectrum of NAC species isolates is highly variable with ongoing difficulty in determining a causal role in symptomatic patients. EXPERT OPINION: We have entered the era of demand for Candida species-specific therapy and although consensus treatment guidelines are emerging, new antifungal agents that target these multiple-azole resistant or relatively resistant vaginal NAC species are urgently needed.

Transcriptomics Reveals Effect of Pulsatilla Decoction Butanol Extract in Alleviating Vulvovaginal Candidiasis by Inhibiting Neutrophil Chemotaxis and Activation via TLR4 Signaling.

The Pulsatilla decoction is a well-known herbal remedy used in clinical settings for treating vulvovaginal candidiasis (VVC). However, the specific mechanism that makes it effective is still unclear. Recent studies have shown that in cases of VVC, neutrophils recruited to the vagina, influenced by heparan sulfate (HS), do not successfully engulf Candida albicans (C. albicans). Instead, they release many inflammatory factors that cause damage to the vaginal mucosa. This study aims to understand the molecular mechanism by which the n-butanol extract of Pulsatilla decoction (BEPD) treats VVC through transcriptomics. High-performance liquid chromatography was used to identify the primary active components of BEPD. A VVC mouse model was induced using an estrogen-dependent method and the mice were treated daily with BEPD (20 mg/kg, 40 mg/kg, and 80 mg/kg) for seven days. The vaginal lavage fluid of the mice was analyzed for various experimental indices, including fungal morphology, fungal burden, degree of neutrophil infiltration, and cytokines. Various assessments were then performed on mouse vaginal tissues, including pathological assessment, immunohistochemistry, immunofluorescence, Western blot (WB), quantitative real-time PCR, and transcriptome assays. Our results showed that BEPD reduced vaginal redness and swelling, decreased white discharge, inhibited C. albicans hyphae formation, reduced neutrophil infiltration and fungal burden, and attenuated vaginal tissue damage compared with the VVC model group. The high-dose BEPD group even restored the damaged vaginal tissue to normal levels. The medium- and high-dose groups of BEPD also significantly reduced the levels of IL-1ß, IL-6, TNF-α, and LDH. Additionally, transcriptomic results showed that BEPD regulated several chemokine (CXCL1, CXCL3, and CXCL5) and S100 alarmin (S100A8 and S100A9) genes, suggesting that BEPD may treat VVC by affecting chemokine- and alarmin-mediated neutrophil chemotaxis. Finally, we verified that BEPD protects the vaginal mucosa of VVC mice by inhibiting neutrophil recruitment and chemotaxis in an animal model of VVC via the TLR4/MyD88/NF-κB pathway. This study provides further evidence to elucidate the mechanism of BEPD treatment of VVC.

Licochalcone A Protects Vaginal Epithelial Cells Against Candida albicans Infection Via the TLR4/NF-κB Signaling Pathway.

Vulvovaginal candidiasis (VVC) is a prevalent condition affecting a significant portion of women worldwide. Licochalcone A (LA), a natural compound with diverse biological activities, holds promise as a protective agent against Candida albicans (C. albicans) infection. This study aims to investigate the potential of LA to safeguard vaginal epithelial cells (VECs) from C. albicans infection and elucidate the underlying molecular mechanisms. To simulate VVC in vitro, VK2-E6E7 cells were infected with C. albicans. Candida albicans biofilm formation, C. albicans adhesion to VK2-E6E7 cells, and C. albicans-induced cell damage and inflammatory responses were assessed by XTT reduction assay, fluorescence assay, LDH assay, and ELISA. CCK-8 assay was performed to evaluate the cytotoxic effects of LA on VK2-E6E7 cells. Western blotting assay was performed to detect protein expression. LA dose-dependently hindered C. albicans biofilm formation and adhesion to VK2-E6E7 cells. Furthermore, LA mitigated cell damage, inhibited the Bax/Bcl-2 ratio, and attenuated the secretion of pro-inflammatory cytokines in C. albicans-induced VK2-E6E7 cells. The investigation into LA's impact on the Toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-κB) pathway revealed that LA downregulated TLR4 expression and inhibited NF-κB activation in C. albicans-infected VK2-E6E7 cells. Furthermore, TLR4 overexpression partially abated LA-mediated protection, further highlighting the role of the TLR4/NF-κB pathway. LA holds the potential to safeguard VECs against C. albicans infection, potentially offering therapeutic avenues for VVC management.

The role of probiotics as adjunct treatment in the prevention and management of gynecological infections: An updated meta-analysis of 35 RCT studies.

OBJECTIVE: The present study aims to conduct a comprehensive meta-analysis of randomized controlled trials (RCTs) investigating the efficacy of probiotics as an adjunct treatment for preventing and treating gynecological infections. MATERIALS AND METHODS: The study adopted a systematic review of scientific databases including PubMed, Cochrane, and EMBASE, using defined MeSH terms. The inclusion and exclusion criteria were set to refine the search, with the data extraction and quality assessment being conducted by two independent investigators. RESULTS: A total of 35 articles, comprising 3751 patients, were included in the meta-analysis. The application of probiotics demonstrated a notable increase in the cure rates of bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) as compared to control groups. A significant BV cure rate (OR: 5.972; 95% CI: 2.62-13.59; p-value: 0.01) was noted with probiotic use, which was even more pronounced when used as an adjunctive treatment with antibiotics (OR: 2.504; 95% CI: 1.03-6.06; p-value: 0.04). Additionally, probiotic use significantly reduced the recurrence rates of BV (OR: 0.34; 95% CI: 0.167-0.71; p-value: 0.004). For VVC, a significant increase in the cure rate was observed in the probiotic group (OR: 3.425; 95% CI: 2.404-4.879; p-value: 0.01), along with a lower recurrence rate (OR: 0.325; 95% CI: 0.175-0.606; p-value: 0.01). CONCLUSION: Our findings underscore the potential role of probiotics as a beneficial adjunctive treatment for gynecological infections, indicating an improved cure rate and decreased recurrence. However, additional well-designed studies are necessary to corroborate these findings.

Insights into the vulvar component of the genitourinary syndrome of menopause (GSM).

Genitourinary syndrome of menopause is a comprehensive term that groups genital, urinary and sexual signs and symptoms mainly due sex hormone deficiency and aging, with a crucial impact on quality of life of midlife women. While this broad definition captures the common underlying physiopathology and the frequent overlap of symptomatology, improving knowledge about different components of genitourinary syndrome of menopause may be relevant for individualized treatment, with possible implications for efficacy, compliance and satisfaction. This narrative review focuses on the vulvar component of genitourinary syndrome of menopause, highlighting anatomical and functional peculiarities of the vulva that are responsible for some of the self-reported symptoms, as well as specific signs at physical examination. Increasing evidence points towards a pivotal role of vulvar vestibular health in the occurrence of sexual pain, one of the most common and distressing symptoms of genitourinary syndrome of menopause, which should be evaluated with validated scales taking a biopsychosocial perspective. This is an essential step in the recognition of different phenotypes of genitourinary syndrome of menopause and in the assessment of the most effective diagnostic and therapeutic algorithm. Menopausal vulvar health deserves more research into tailored non-hormonal and hormonal treatment options.

From plants to particles: herbal solutions and nanotechnology combating resistant vulvovaginal candidiasis.

Despite having current advanced therapy, vulvovaginal candidiasis (VVC) remains a common yet debated healthcare-associated topic worldwide due to multi-drug resistance Candida species. In our review, we outlined and highlighted upcoming values with scope of existing and emerging information regarding the possibility of using various natural molecules combined with modern technology that shows promising anti-candida activity in VVC. Furthermore, in this review, we compiled herbal drug molecules and their nanocarriers approach for enhancing the efficacy and stability of herbal molecules. We have also summarized the patent literature available on herbal drug molecules and their nanoformulation techniques that could alternatively become a new innovative era to combat resistance VVC.

There is a type of fungi called Candida that is responsible for infections like vulvovaginal candidiasis in the human vagina. Due to resistance of currently available antifungal medicines, there are side effects on the body. Therefore, researchers are studying and preparing natural-based medicine from plants which may provide very good effects on human health. Also, herbal-based medicines have shown evidence based good antifungal activity. Combinations of herbal drugs with very small-sized particles called nanomaterials have added advantage as it helps herbs (drug) to reach their target. Its activity is enhanced as it stays for longer time in the body. So, in the future more research is needed to make sure plant medicines are safe and work well on vaginal infections and its uses should be promoted so that could be a good solution for treating vaginal candidiasis.

Exploring the antifungal potential of Annona muricata leaf extract-loaded hydrogel in treating vulvovaginal candidiasis.

Vulvovaginal candidiasis, mostly caused by Candida albicans, remains a prevalent concern in women's health. Annona muricata L. (Annonaceae), a plant native from Brazil, is well-known for its therapeutic potential, including antitumor, anti-inflammatory, and antimicrobial properties. This study presents an innovative hydrogel formulation containing the ethanolic extract from A. muricata leaves designed to control C. albicans in an in vivo model of vulvovaginal candidiasis. Here, we report the development, thermal, physicochemical and rheological characterization of a Carbopol®-based hydrogel containing A. muricata extract. Furthermore, we evaluated its activity in a vulvovaginal candidiasis in vivo model. Thermal analyses indicated that the addition of the extract increased the polymer-polymer and polymer-solvent interactions.Rheological analysis showed a decrease in the viscosity and elasticity of the formulation as the A. muricata extract concentration increased, suggesting a liquid-like behavior. After treatment with the Carbopol®-based hydrogel with A. muricata, our in vivo results showed a significant reduction in vulvovaginal fungal burden and infection, as well as a reduction in mucosal inflammation. The current research opens up possibilities for the application of the Carbopol®-based hydrogel with A. muricata as a natural therapeutic option for the treatment of vulvovaginal candidiasis.

Efficacy and safety of oral ibrexafungerp in Chinese patients with vulvovaginal candidiasis: a phase III, randomized, double-blind study.

PURPOSE: To evaluate the efficacy and safety of oral ibrexafungerp (HS-10366) versus placebo in Chinese patients with vulvovaginal candidiasis (VVC). METHODS: A double-blind, placebo-controlled, randomized, multicenter phase III study was conducted in symptomatic VVC patients. Patients received (2:1) twice-daily oral ibrexafungerp 300 mg or matching placebo for 1 day. The primary endpoint was clinical cure (vulvovaginal signs and symptoms [VSS] score = 0) at test-of-cure (TOC) on day 11 ± 3. The secondary endpoints included mycological eradication, overall response, and clinical improvement (VSS score ≤ 1) at TOC, and vulvovaginal symptom resolution at follow-up on day 25 ± 4. RESULTS: In total, 360 patients were included in the modified intention-to-treat set (defined as positive Candida cultured and receiving at least one study drug; 239 for ibrexafungerp, 121 for placebo). Compared with placebo, patients receiving ibrexafungerp had a significantly higher proportion of clinical cure (51.0% vs. 25.6%), mycological eradication (55.6% vs. 18.2%), overall response (33.9%, vs. 8.3%) at TOC and complete symptom resolution (74.5% vs. 39.7%, all P < 0.001) at follow-up. Subgroup analysis of clinical cure indicated that patients with C. albicans could benefit from ibrexafungerp over placebo. A similar benefit trend was also observed in those with non-albicans Candida by post-hoc analysis. Further analyses revealed similar efficacy of ibrexafungerp between patients with fluconazole non-susceptible C. albicans and fluconazole susceptible C. albicans regarding clinical cure and mycological eradication. Ibrexafungerp was generally well tolerated. Adverse events were primarily gastrointestinal and were mainly mild in severity. CONCLUSIONS: As a first-in-class antifungal agent, ibrexafungerp demonstrated promising efficacy and favorable safety for VVC treatment in Chinese patients. CHINADRUGTRIALS.ORG.
