  • 文章类型: Journal Article
    目的:外阴阴道念珠菌病(VVC)是一种常见的黏膜真菌感染,白色念珠菌是主要病原体。NLRP3炎性体在VVC中起重要作用,但潜在的机制是未知的。
    方法:阴道上皮细胞分为三组:对照组,白色念珠菌株SC5314(野生型,WT),和WT+MattCooper化合物950(MCC950,特异性NLRP3抑制剂)。人阴道上皮细胞用1μmol/LMCC950预处理2小时后,将白色念珠菌(MOI=1)与人阴道上皮细胞共培养12小时。收集细胞上清液,检测到LDH,ELISA法测定IL-1β和IL-18水平。通过蛋白质印迹分析测量焦亡相关蛋白NLRP3,Caspase-1p20和GSDMD的表达。免疫荧光法检测GSDMD(GSDMD-N)的焦亡相关N端蛋白表达。
    结果:在这项研究中,我们表明WT白色念珠菌菌株诱导阴道上皮细胞的焦亡,如LDH和促炎细胞因子水平以及焦亡相关蛋白NLRP3,Caspase-1p20和GSDMD-N的上调水平所示。MCC950逆转了阴道上皮细胞中这些蛋白和促炎细胞因子表达的变化。
    结论:C.白色念珠菌激活NLRP3炎性体以诱导阴道上皮细胞焦亡。MCC950抑制NLRP3炎性体,减少阴道上皮细胞焦凋亡,降低了炎性细胞因子的释放。
    OBJECTIVE: 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.
    METHODS: 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-1β 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.
    CONCLUSIONS: 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.

    唑类抗真菌药物通常用于治疗外阴阴道念珠菌病(VVC)。在现实世界中尚未系统地分析唑类药物的肾毒性和发育毒性。我们使用FDA不良事件报告系统(FAERS)来调查与咪唑治疗VVC相关的不良事件(AE)。使用OpenVigil2.1检索FAERS数据(从2004年第1季度到2022年第3季度),并根据监管活动医学词典(MedDRA)检索和标准化AE。在前10个系统器官类(SOC)中,所有四种药物都被发现患有肾脏和泌尿系统疾病以及怀孕。我们发现了重要的信号,包括克霉唑[膀胱移行细胞癌,(报告赔率比,ROR=291.66)],[胎儿死亡,(ROR=10.28)],酮康唑[肾性贫血(ROR=22.1)],[胎膜早破(ROR=22.9146.45,11,3)],咪康唑[血尿(ROR=19.03)],[新生儿败血症(ROR=123.71)],[自然流产(ROR=5.98)],益康唑[急性肾损伤(ROR=4.41)],[自然流产(ROR=19.62)]。我们还发现了未报告的新的不良反应。因此,当使用咪唑药物进行治疗时,有必要密切监测患者的肾功能,注意胎儿在怀孕期间的发育毒性,并意识到可能发生的潜在不良反应。
    Azole antifungal drugs are commonly used to treat vulvovaginal candidiasis (VVC). The nephrotoxicity and developmental toxicity of azole drugs have not been systematically analyzed in the real world. We used the FDA Adverse Event Reporting System (FAERS) to investigate the adverse events (AEs) associated with imidazole therapy for VVC. FAERS data (from quarter 1 2004 to quarter 3 2022) were retrieved using OpenVigil 2.1, and AEs were retrieved and standardized according to the Medical Dictionary for Regulatory Activities (MedDRA). In the top 10 System Organ Class (SOC), all four drugs have been found to have kidney and urinary system diseases and pregnancy. We found significant signals, including clotrimazole [bladder transitional cell carcinoma, (report odds ratio, ROR = 291.66)], [fetal death, (ROR = 10.28)], ketoconazole[nephrogenic anemia (ROR = 22.1)], [premature rupture of membranes (ROR = 22.91 46.45, 11, 3)], Miconazole[hematuria (ROR = 19.03)], [neonatal sepsis (ROR = 123.71)], [spontaneous abortion (ROR = 5.98)], Econazole [acute kidney injury (ROR = 4.41)], [spontaneous abortion (ROR = 19.62)]. We also discovered new adverse reactions that were not reported. Therefore, when using imidazole drugs for treatment, it is necessary to closely monitor the patient\'s renal function, pay attention to the developmental toxicity of the fetus during pregnancy, and be aware of potential adverse reactions that may occur.

    背景:外阴阴道念珠菌病(VVC)是引起阴道和/或外阴炎症的真菌感染。症状包括瘙痒,刺激,和放电。VVC通常在初级保健和,尽管症状轻微,心理负担,对女性的生活质量有重大影响。英国指南支持通过口服或局部唑类抗真菌剂进行治疗。最近的证据证明了新型非唑类抗真菌剂的优越性。因此,对两种抗真菌药物进行严格的财务评估对于英国初级保健中最佳的VVC治疗分配是必要的。
    目的:评估ibrexafungerp与金标准氟康唑作为NHS内VVC一线治疗的成本效益。
    方法:系统评价ibrexafungerp和氟康唑在急性VVC中的疗效。使用DOVE试验的健康结果数据启动了成本效益分析,a第二阶段RCT。英镑成本以货币单位确定,和有效性确定为减少后续药物的需要。
    结果:确定了2185.74英镑的增量成本效益比。这表明口服ibrexafungerp比氟康唑更昂贵,但效果略好。因此具有不利的净收益。考虑后续药物组合和市场价格,进行了两项敏感性分析。这为计算出的成本效益比提供了信心。
    结论:该分析突出了氟康唑在当前英国指南中的成本效益和优势。
    BACKGROUND: Vulvovaginal Candidiasis (VVC) is a fungal infection causing inflammation of the vagina and/or the vulva. Symptoms include itching, irritation, and discharge. VVC presents commonly across primary care and, despite its mild symptoms, carries psychological burden and has a significant impact on women\'s quality of life. UK guidelines support treatment via oral or topical azole antifungal agents. Recent evidence attests to the superiority of novel non-azole antifungals. Thus, rigorous financial assessment of both antifungals is necessary for optimal VVC treatment allocation in UK primary care.
    OBJECTIVE: To evaluate the cost-effectiveness of ibrexafungerp against the gold standard fluconazole as first-line treatment of VVC within the NHS.
    METHODS: A systematic review on the efficacy of ibrexafungerp and fluconazole in acute VVC was conducted. Cost-effectiveness analysis was initiated using health outcome data from the DOVE trial, a Phase 2 RCT. Costs in pound sterling were ascertained in monetary units, and effectiveness determined as reduced need for follow-up medication.
    RESULTS: An incremental cost-effectiveness ratio of £2185.74 was determined. This suggests oral ibrexafungerp being largely more costly yet slightly more effective than fluconazole, and thus has unfavourable net benefit. Two sensitivity analyses were conducted considering follow-up medication combination and market price, which provided confidence in the calculated cost-effectiveness ratio.
    CONCLUSIONS: This analysis highlights fluconazole\'s cost-effectiveness in current UK guidelines and favourability.

    由于其普遍性,复发,以及耐药性的出现,念珠菌阴道炎显著影响女性的健康。虽然肉桂精油(CEO)具有抗真菌活性,其疏水特性限制了其临床应用。
    为了克服这一挑战,采用纳米乳化技术制备肉桂精油纳米乳液(CEO@NE),研究了其对念珠菌阴道炎的体内外治疗效果和作用机制。
    CEO@NE,由4%的CEO组成,78%蒸馏水,用超声波纳米乳化法制备了18%的吐温80。物理性质,抗念珠菌活性,细胞毒性,探讨了CEO@NE的免疫调节潜力和储存稳定性。随后,在小鼠中研究了阴道内CEO@NE治疗对念珠菌性阴道炎的影响.为了理解CEO@NE的可能机制,进行分析以确定白色念珠菌中细胞内活性氧(ROS)的产生。
    CEO@NE,与液滴尺寸小于100纳米和强大的储存稳定性长达8周,表现出与首席执行官相当的抗念珠菌活性。浓度低于400μg/mL的CEO@NE对鼠脾细胞没有细胞毒性和免疫调节作用。CEO@NE的阴道内治疗(400μg/mL,20μL/天/小鼠,连续5天)抑制念珠菌定植,改善的组织病理学变化,并抑制了白色念珠菌阴道内攻击的小鼠的炎性细胞因子产生。值得注意的是,这种治疗保留了对阴道健康至关重要的阴道乳酸菌(LAB)的密度。与CEO@NE共培养白色念珠菌揭示了细胞内ROS产生的浓度依赖性增加和随后的细胞死亡。此外,将LPS刺激的小鼠脾细胞与CEO@NE共培养可减少细胞因子的产生。
    这一发现提供了对CEO@NE治疗念珠菌阴道炎的可想而知的抗真菌和抗炎机制的见解。CEO@NE提供了一个有希望的途径来解决当前治疗的局限性,为念珠菌阴道炎的治疗提供了新的策略。
    UNASSIGNED: Due to its prevalence, recurrence, and the emergence of drug-resistance, Candida vaginitis significantly impacts the well-being of women. Although cinnamon essential oil (CEO) possesses antifungal activity, its hydrophobic properties limit its clinical application.
    UNASSIGNED: To overcome this challenge, a nanoemulsification technology was employed to prepare cinnamon essential oil-nanoemulsion (CEO@NE), and its therapeutic efficacy and action mechanism for Candida vaginitis was investigated in vivo and in vitro.
    UNASSIGNED: CEO@NE, composed of 4% CEO, 78% distilled water, and 18% Tween 80, was prepared by ultrasonic nanoemulsification. The physical properties, anti-Candida activity, cytotoxicity, immunomodulatory potential and storage stability of CEO@NE were explored. Subsequently, the effect of intravaginal CEO@NE treatment on Candida vaginitis was investigated in mice. To comprehend the possible mechanism of CEO@NE, an analysis was conducted to ascertain the production of intracellular reactive oxygen species (ROS) in C. albicans.
    UNASSIGNED: CEO@NE, with the droplet size less than 100 nm and robust storage stability for up to 8 weeks, exhibited comparable anti-Candida activity with CEO. CEO@NE at the concentration lower than 400 μg/mL had no cytotoxic and immunomodulatory effects on murine splenocytes. Intravaginal treatment of CEO@NE (400 μg/mL, 20 μL/day/mouse for 5 consecutive days) curbed Candida colonization, ameliorated histopathological changes, and suppressed inflammatory cytokine production in mice intravaginally challenged with C. albicans. Notably, this treatment preserved the density of vaginal lactic acid bacteria (LAB) crucial for vaginal health. Co-culturing C. albicans with CEO@NE revealed concentration-dependent augmentation of intracellular ROS generation and ensuing cell death. In addition, co-culturing LPS-stimulated murine splenocytes with CEO@NE yielded a decrease in the generation of cytokines.
    UNASSIGNED: This discovery provides insight into the conceivable antifungal and anti-inflammatory mechanisms of CEO@NE to tackle Candida vaginitis. CEO@NE offers a promising avenue to address the limitations of current treatments, providing novel strategy for treating Candida vaginitis.

    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.
    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).
    CONCLUSIONS: 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.

    白色念珠菌(C.白色念珠菌)可以表现为共生酵母定植在阴道粘膜上,在这种情况下,上皮可以耐受。当上皮耐受性破坏时,由于白色念珠菌过度生长和菌丝形成,产生的炎症反应和细胞损伤导致外阴阴道念珠菌病(VVC)症状。这里,我们重点研究了白色念珠菌感染后阴道上皮细胞线粒体活性氧(mtROS)的诱导和真菌负荷的参与,这种诱导中的形态发生和念珠菌蛋白酶(CL)的产生。生物发光(BLI)白色念珠菌,白色念珠菌PCA-2和白色念珠菌529L菌株用于体外感染模型,包括重建的阴道上皮细胞(RVE),从A-431细胞系开始产生。通过使用MitoSOX™Red探针动力学测量mtROS的产生。还评估了白色念珠菌对RVE和白色念珠菌增殖的诱导细胞损伤的效力。白色念珠菌诱导阴道上皮细胞快速释放mtROS,与真菌负荷和菌丝形成的增加并行。在相同的实验条件下,529L白色念珠菌菌株,已知在CL生产中有缺陷,诱导少量mtROS释放,表明CL在引起上皮mithocondrial激活中的关键作用。C.白色念珠菌PCA-2,不能形成菌丝,与BLI白色念珠菌酵母相比,诱导的mtROS产生相当但较慢。通过ROS清除剂减少mtROS,在RVE感染期间观察到真菌负荷增加,但在非生物表面生长的真菌培养物中未观察到。总的来说,我们得出结论,CL,超过真菌负荷和菌丝形成,似乎在上皮细胞快速激活mtROS和诱导细胞损伤中起关键作用,并且mtROS是阴道上皮细胞对白色念珠菌反应的关键因素。
    Candida albicans (C. albicans) can behave as a commensal yeast colonizing the vaginal mucosa, and in this condition is tolerated by the epithelium. When the epithelial tolerance breaks down, due to C. albicans overgrowth and hyphae formation, the generated inflammatory response and cell damage lead to vulvovaginal candidiasis (VVC) symptoms. Here, we focused on the induction of mitochondrial reactive oxygen species (mtROS) in vaginal epithelial cells after C. albicans infection and the involvement of fungal burden, morphogenesis and candidalysin (CL) production in such induction. Bioluminescent (BLI) C. albicans, C. albicans PCA-2 and C. albicans 529L strains were employed in an in vitro infection model including reconstituted vaginal epithelium cells (RVE), produced starting from A-431 cell line. The production of mtROS was kinetically measured by using MitoSOX™ Red probe. The potency of C. albicans to induced cell damage to RVE and C. albicans proliferation have also been evaluated. C. albicans induces a rapid mtROS release from vaginal epithelial cells, in parallel with an increase of the fungal load and hyphal formation. Under the same experimental conditions, the 529L C. albicans strain, known to be defective in CL production, induced a minor mtROS release showing the key role of CL in causing epithelial mithocondrial activation. C. albicans PCA-2, unable to form hyphae, induced comparable but slower mtROS production as compared to BLI C. albicans yeasts. By reducing mtROS through a ROS scavenger, an increased fungal burden was observed during RVE infection but not in fungal cultures grown on abiotic surface. Collectively, we conclude that CL, more than fungal load and hyphae formation, seems to play a key role in the rapid activation of mtROS by epithelial cells and in the induction of cell-damage and that mtROS are key elements in the vaginal epithelial cells response to C. albicans.

    由细菌性阴道病(BV)和外阴阴道念珠菌病(VVC)引起的混合性阴道炎是最普遍的形式,并在全球范围内提出了重大的治疗挑战。因为,单一疗法的施用导致随后的复发性感染,完全根除两种病原体的协同治疗迫切需要管理混合阴道情况并防止其复发。当前的研究集中在探索植物化学物质对白色念珠菌和阴道念珠菌(Galleriamellonella)的个体和混合种的体外和体内毒力性状的协同抑制功效。五种植物化学物质(香芹酚,百里酚,肉桂醛,丁香酚,和冰片)筛选了与柠檬醛的协同作用[(Ct)由于其无数的治疗潜力而作为主要分子],香芹酚(Ca)与柠檬醛的组合具有良好的协同作用。时间杀死动力学和一分钟的接触杀死试验证明了Ct-Ca组合在30分钟和一分钟的时间间隔内对单物种和双物种的显着杀菌效果,分别。此外,Ct-Ca的亚CMIC(协同组合MIC)显着根除了成熟的生物膜,并显着降低了白色念珠菌和阴道念珠菌的毒力属性(即,酵母向菌丝转变,成丝,蛋白酶生产,和疏水性指数),在单一和双重物种状态。使用体外(人红细胞)和体内(Galleriamellonella)模型验证了Ct-Ca组合的无毒性质。此外,使用无脊椎动物模型系统G.mellonella进行体内功效评估和随后的组织病理学研究,这进一步确定了Ct-Ca组合在抵抗由白色念珠菌和阴道念珠菌的个体和混合种引起的感染中的有效性。同时,目前的工作是首次描述白色念珠菌和阴道念珠菌混合物种在其生长和生物膜状态下的体外相互作用,共同强调了广受好评的植物化学物质作为针对混合性阴道炎的组合协同疗法的有希望的治疗潜力。
    Mixed vaginitis due to bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) is the most prevalent form and presents a significant therapeutic challenge globally. Since, the administration of monotherapy leads to subsequent recurrent infections, synergistic therapy that completely eradicates both pathogens is of dire need to manage mixed vaginities scenario and to prevent its recurrence. The current investigation was focused on exploring the synergistic inhibitory efficacy of phytochemicals against the virulence traits of individual and mixed species of C. albicans and G. vaginalis in vitro and in vivo (Galleria mellonella). Out of five phytochemicals (carvacrol, thymol, cinnamaldehyde, eugenol, and borneol) screened for synergism with citral [(Ct) as the prime molecule owing to its myriad therapeutic potential], carvacrol (Ca) in combination with citral exhibited promising synergistic effect. Time-kill kinetics and one-minute contact-killing assays demonstrated the phenomenal microbicidal effect of Ct-Ca combination against both mono and dual-species within 30 min and one-minute time intervals, respectively. Furthermore, the sub-CMICs (synergistic combinatorial MIC) of Ct-Ca have significantly eradicated the mature biofilms and remarkably reduced the virulence attributes of both C. albicans and G. vaginalis (viz., yeast to hyphae transition, filamentation, protease production, and hydrophobicity index), in single and dual species states. The non-toxic nature of Ct-Ca combination was authenticated using in vitro (human erythrocyte cells) and in vivo (Galleria mellonella) models. In addition, the in vivo efficacy evaluation and subsequent histopathological investigation was done using the invertebrate model system G. mellonella, which further ascertained the effectiveness of Ct-Ca combination in fighting off the infection caused by individual and mixed species of C. albicans and G. vaginalis. Concomitantly, the current work is the first of its kind to delineate the in vitro interaction of C. albicans and G. vaginalis mixed species at their growth and biofilm states, together emphasizes the promising therapeutic potential of acclaimed phytochemicals as combinatorial synergistic therapy against mixed vaginitis.

    外阴阴道念珠菌病(VVC)是女性阴道分泌物的最常见原因。本研究旨在研究补充植物提取物的乳酸菌培养物的协同抗虫作用。在600株乳酸菌中,41个分离物对白色念珠菌ATCC10231表现出抑制活性。41种无细胞上清液中的6种表现出最有效的抗菌和抗虫活性。它们还抑制了白色念珠菌的临床分离株,引起VVC和非C.白色的。通过最低的部分抑制浓度指数(FICI=0.5)证明了卷曲乳杆菌84/7和罗伊氏乳杆菌89/4之间的协同作用。细菌组合的合生元培养物,用菊芋培养(H.结节)提取物,还表现出对测试的白色念珠菌的最强抑制。在该合生元培养物的所选无细胞上清液中孵育12小时后,生物膜形成减少。用蛋白酶K和胰蛋白酶处理后,但在加热条件下没有,粗提物的抗虫活性丧失。这表明它可能是一种热稳定的物质。总之,联合使用84/7型乳球菌和89/4型罗伊氏乳杆菌可能是抑制念珠菌感染和生物膜形成的一个有希望的候选者,作为阴道生物治疗产品成分的潜在用途。
    Vulvovaginal candidiasis (VVC) is the most common cause of vaginal discharge among women. The present study aimed to investigate the synergistic anticandidal effect of lactobacillus cultures supplemented with plant extracts. Among 600 isolates of lactic acid bacteria, 41 isolates exhibited inhibitory activity against Candida albicans ATCC10231. Six out of 41 cell-free supernatants demonstrated the most potent antibacterial and anticandidal activities. They also inhibited the clinical isolates of C. albicans, causing VVC and non-C. albicans. The synergistic effect between Lactobacillus crispatus 84/7 and Limosilactobacillus reuteri 89/4 was demonstrated by the lowest fractional inhibitory concentration index (FICI = 0.5). The synbiotic culture of bacterial combination, cultured with Jerusalem artichoke (H. tuberosus) extract, also exhibited the strongest inhibition against the tested C. albicans. Biofilm formation decreased after 12 h of incubation in the selected cell-free supernatants of this synbiotic culture. The anticandidal activity of crude extracts was lost after treatment with proteinase K and trypsin but not with heating conditions, suggesting that it may be a heat-stable substance. In conclusion, the combination of L. crispatus 84/7 and L. reuteri 89/4 with H. tuberosus may be a promising candidate for inhibiting Candida infection and biofilm formation, with the potential use as ingredients in vaginal biotherapeutic products.
