RESUMO

BACKGROUND: Vaginal candidiasis (VC) commonly affects pregnant women. Traditionally, clotrimazole vaginal tablets (CLO) have been the cornerstone of management. However, sertaconazole ovules (SER) offer a novel topical antimycotic option. This double-blinded, randomized trial evaluated the efficacy of single-dose SER and CLO in treating acute VC during pregnancy. METHODS: From June 2020 to May 2021, this trial recruited pregnant women aged ≥ 18 years with VC symptoms (abnormal vaginal discharge and/or vulvar/vaginal itching) confirmed by microscopy. Participants with ≥ 4 VC episodes in the prior year, immunocompromised status, or imidazole contraindications and those who were absent at the 2-week follow-up were excluded. Participants were randomized to receive either 300 mg SER or 500 mg CLO. Evaluations 2 weeks after the initial medication administration included clinical cure (self-reported resolution of all symptoms), microscopic cure (pseudohyphal absence), patient satisfaction, side effects, and time to clinical cure. Participants with persistent VC received weekly SER doses until delivery. Assessments of recurrence and pregnancy outcomes were done. RESULTS: The analysis included 96 participants (48 per group, mean age 27.4 ± 7.4 years, gestational age at diagnosis 22.9 ± 6.4 weeks). Without statistical significance, SER achieved a higher clinical cure rate (62.5% vs 50%, p = 0.217; a mean difference of 12.5%, 95%CI: -17.5% to 42.5%; and a rate ratio of 1.25, 95%CI: 0.71 to 2.23) and a lower microscopic cure (47.9% vs. 62.5%, p = 0.151; a mean difference of -14.6%, 95%CI: -44.3% to 15.1%; and a rate ratio of 0.77, 95%CI: 0.43 to 1.37). The two groups had comparable times to clinical cure (SER: 3.1 ± 1.8 days, CLO: 3.4 ± 2.7 days; p = 0.848) and substantial satisfaction rates (SER: 66.7%, CLO: 60.4%; p = 0.753). No side effects were reported. Of 60 participants who gave birth at Siriraj Hospital, there were no significant differences in pregnancy outcomes. Repeated SER dosing eradicated symptoms and enhanced the microscopic cure rate. Recurrence was observed in four SER and two CLO participants within 1-2 months. CONCLUSION: In the treatment of acute VC during pregnancy, 300 mg SER and 500 mg CLO exhibited comparable efficacy in terms of clinical and microscopic cure rates, satisfaction, side effects, time to clinical cure, recurrence rates, and pregnancy outcomes. TRIAL REGISTRATION: TCTR20190308004 (registration date March 8, 2019).

RESUMO

Vulvovaginal candidiasis (VVC) is a real gynecological problem among women of reproductive age from 15 to 49. A recent analysis showed that 75% of women will have an occurrence at least once per year, while 5% are observed to have recurrent vaginal mycosis-these patients may become unwell four or more times a year. This pathology is caused in 85-90% of cases by fungi of the Candida albicans species. It represents an intractable medical problem for female patients due to pain and pruritus. Due to the observation of an increasing number of strains resistant to standard preparations and an increase in the recurrence of this pathology when using local or oral preferential therapy, such as fluconazole, an analysis was launched to develop alternative methods of treating VVC using herbs such as dill, turmeric, and berberine. An in-depth analysis of databases that include scientific articles from recent years made it possible to draw satisfactory conclusions supporting the validity of herbal therapy for the pathology in question. Although phytotherapy has not yet been approved by the Food and Drug Administration, it appears to be a promising therapeutic solution for strains that are resistant to existing treatments. There is research currently undergoing aimed at comparing classical pharmacotherapy and herbal therapy in the treatment of vaginal candidiasis for the purpose of increasing medical competence and knowledge for the care of the health and long-term comfort of gynecological patients.

RESUMO

Cases of vulvovaginitis caused by Cryptococcus genus are exceedingly uncommon, with only a handful of instances having been described for this causative species. This report describes a rare case of vulvovaginitis suspected to be caused by Cryptococcus victoriae in a 58-year-old woman residing in an urban area of Hanoi city, Vietnam. The patient with a 10-year history of depression and type 2 diabetes mellitus was admitted to the hospital due to vulvar itching and vaginal discharge. Vaginal swabs confirmed the presence of a yeast infection by direct microscopic examination with 10% KOH and culture on CHROMagar Candida. The yeast was identified as C victoriae using genetic sequencing tools. The patient's treatment plan involved topical clotrimazole and a daily oral dose of 200 mg of itraconazole for 7 days. This comprehensive treatment approach resulted in the patient's full recovery. This is the first reported case of vulvovaginitis attributed to C victoriae in humans worldwide.

RESUMO

OBJECTIVES: The study's aim is to assess if vulvar psoriasis and candidiasis may be distinguished by clinical presentation and histopathologic appearance. METHODS: The pathology database identified biopsies with corneal or subcorneal neutrophils, acanthosis, and dermal lymphocytic infiltrate. Exclusions were age younger than 18 years and unavailable or uninterpretable slides. Clinical data included demographics, comorbid conditions, symptoms, examination, microbiology, treatment, and response. Histopathologic review documented site, thickness, and characteristics of stratum corneum and epidermis, distribution of neutrophils, and infiltrate. Cases were stratified by microbiologic presence or absence of Candida albicans. RESULTS: Biopsies from 62 women with median age of 60 years were associated with C. albicans on vulvovaginal culture in 28 (45%), whereas 26 (42%) were negative, and 8 (13%) lacked microbiologic assessment. Swab-positive women were more likely to have diabetes, receive prereferral estrogen, and report vulvar pain. Specialist clinical impression was candidiasis in 33 (53%), psoriasis in 11 (18%), comorbid candidiasis and psoriasis in 7 (11%), dermatitis in 10 (16%), and unknown in 2 (3%). Visible fungal organisms occurred in 16 (26%) cases and were associated with diabetes and satellite lesions. Other than presence of organisms, there were no histopathologic differences stratified by microbiologic result. CONCLUSIONS: The histopathologic triad of corneal/subcorneal neutrophils, acanthosis, and dermal lymphocytic infiltrate is common to vulvar psoriasis and candidiasis, and clinical features do not reliably distinguish between them. Microbiologic assessment and single-agent treatment are useful strategies to clarify the diagnosis.

RESUMO

Recurrent vulvovaginal candidiasis (RVVC) due to fluconazole resistance in Candida albicans isolates causes a wide range of complications. A number of 63 Candida albicans isolates obtained from vulvovaginal candidiasis (VVC) were identified by Internal Transcribed Spacer-Restriction Fragment Length Polymorphism (ITS-RFLP). Antifungal susceptibility testing was performed by broth microdilution method according to the CLSI protocol. The role of CDR1 and MDR1 genes in progress of VVC to RVVC was examined and the activity of virulence-related enzymes was assessed. Candida albicans was diagnosed in 62.4 % cases, of which 22.2 % were confirmed as RVVC. Voriconazole was the most active drug among five tested antifungals. The mean expression level of CDR1 and MDR1 was higher in RVVC isolates compared to multidrug azole-resistant VVC isolates. Our results demonstrated that the expression of CDR1 and MDR1 and the level of phospholipase and proteinase activities could be quite important to induce fluconazole resistance in C. albicans and to progress of VVC to become RVVC in involved patients.

RESUMO

Candida albicans is the most leading cause of life-threatening fungal invasive infections, especially for vulvovaginal candidiasis (VVC). Resistance and tolerance to common fungicide has risen great demands on alternative strategies for treating C. albicans infections. In the present study, ferroptosis has been proven to occur in C. albicans by directly exposed to FeSO4 via induing hallmarks of ferroptosis, including Fe2+ overload burden, ROS eruption and lipid peroxidation. Transcriptomic profile gave the great hints of the possible mechanism for fungal ferroptosis that FeSO4 disturb pathways associated to ribosome, tyrosine metabolism, triglyceride metabolism and thiamine metabolism, thus mobilizing death-related gene synthesis. Inspired by the results, a FeSO4-loaded hydrogel was prepared as an antifungal agent to treat C. albicans infection. This hydrogel exhibited excellent dressing properties and maintained superior antifungal activity by characterization tests. Besides, mice treated by this composite hydrogel displayed excellent therapeutic efficacy. These results highlighted the potential therapeutic use of FeSO4 as an innovative strategy in treating C. albicans infections by targeting ferroptosis.

RESUMO

BACKGROUND: Candida albicans is the most common fungus that causes vaginal candidiasis in immunocompetent women and catastrophic infections in immunocompromised patients. The treatment of such infections is hindered due to the increasing emergence of resistance to azoles in C. albicans. New treatment approaches are needed to combat candidiasis especially in the dwindled supply of new effective and safe antifungals. The resistance to azoles is mainly attributed to export of azoles outside the cells by means of the efflux pump that confers cross resistance to all azoles including fluconazole (FLC). OBJECTIVES: This study aimed to investigate the possible efflux pump inhibiting activity of fusidic acid (FA) in C. albicans resistant isolates and the potential use of Fusidic acid in combination with fluconazole to potentiate the antifungal activity of fluconazole to restore its activity in the resistant C. albicans isolates. METHODS: The resistance of C. albicans isolates was assessed by determination of minimum inhibitory concentration. The effect of Fusidic acid at sub-inhibitory concentration on efflux activity was assayed by rhodamine 6G efflux assay and intracellular accumulation. Mice model studies were conducted to evaluate the anti-efflux activity of Fusidic acid and its synergistic effects in combination with fluconazole. Impact of Fusidic acid on ergosterol biosynthesis was quantified. The synergy of fluconazole when combined with Fusidic acid was investigated by determination of minimum inhibitory concentration. The cytotoxicity of Fusidic acid was tested against erythrocytes. The effect of Fusidic acid on efflux pumps was tested at the molecular level by real-time PCR and in silico study. In vivo vulvovaginitis mice model was used to confirm the activity of the combination in treating vulvovaginal candidiasis. RESULTS: Fusidic acid showed efflux inhibiting activity as it increased the accumulation of rhodamine 6G, a substrate for ABC-efflux transporter, and decreased its efflux in C. albicans cells. The antifungal activity of fluconazole was synergized when combined with Fusidic acid. Fusidic acid exerted only minimal cytotoxicity on human erythrocytes indicating its safety. The FA efflux inhibitory activity could be owed to its ability to interfere with efflux protein transporters as revealed by docking studies and downregulation of the efflux-encoding genes of both ABC transporters and MFS superfamily. Moreover, in vivo mice model showed that using fluconazole-fusidic acid combination by vaginal route enhanced fluconazole antifungal activity as shown by lowered fungal burden and a negligible histopathological change in vaginal tissue. CONCLUSION: The current findings highlight FA's potential as a potential adjuvant to FLC in the treatment of vulvovaginal candidiasis.

RESUMO

Recurrent infectious vaginitis can lead to significant morbidity, patient frustration, and health care costs. The most common causes are bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC); however, other infectious and noninfectious etiologies should be considered in patients with recurrent symptoms. A detailed history and physical examination with appropriate testing at the time of symptoms is critical to establishing a correct diagnosis. Management options for recurrent BV and VVC are limited. Complex cases including those with atypical symptoms, negative testing for common causes, refractory symptoms despite appropriate therapy or recurrences during suppressive therapy will require referral to specialist care.

RESUMO

Vulvovaginal candidiasis (VVC) caused by Candida glabrata (C. glabrata) is more persistent and resistant to treatment than when caused by Candida albicans (C. albicans) and has been on the rise in recent years. The n-butanol extract of Pulsatilla Decoction (BEPD) has been shown to be effective in treating VVC caused by C. glabrata, but the underlying mechanism of action remains unclear. In this study, the experimenter conducted in vitro and in vivo experiments to explore the effects of BEPD on the virulence factors of C. glabrata, as well as its efficacy, with a focus on possible immunological mechanism in VVC caused by C. glabrata. The contents of Anemoside B4, Epiberberine, Berberine, Aesculin, Aesculetin, Phellodendrine and Jatrorrhizine in BEPD, detected by high-performance liquid chromatography, were 31,736.64, 13,529.66, 105,143.72, 19,406.20, 4952.67, 10,317.03, 2489.93 µg/g, respectively. In vitro experiments indicated that BEPD moderately inhibited the growth of C. glabrata, its adhesion, and biofilm formation, and affected the expression of efflux transporters in the biofilm state. In vivo experiments demonstrated that BEPD significantly reduced vaginal inflammatory manifestation and the release of proinflammatory cytokines and LDH in mice with VVC caused by C. glabrata. Moreover, it inhibited the Phosphorylation of EGFR, ERK, P38, P65, and C-Fos proteins. The results suggested that although BEPD moderately inhibits the growth and virulence factors of C. glabrata in vitro, it can significantly reduce vaginal inflammation by down-regulating the EGFR/MAPK signaling pathway in mice with VVC infected by C. glabrata.

RESUMO

OBJECTIVE: To investigate the non-inferiority of efficacy and tolerability of Lactobacillus plantarum P 17630 soft vaginal capsules compared to the antifungal therapy with miconazole nitrate 400 mg soft vaginal capsules in patients with symptomatic vulvovaginal infection due to Candida. PATIENTS AND METHODS: Adult women with vulvovaginal candidiasis were randomized to either L. plantarum P17630 100,000,000 CFU soft vaginal capsules by vaginal route each day for 3 or 6 consecutive days or miconazole nitrate 400 mg soft vaginal capsule. Visual Analog Scale (VAS) scores for vaginitis symptoms were used, and vaginal fluid interleukin 6 (IL6) was dosed. The study was registered in EudraCT database (code LPP17630-C-018; number: 2018-003095-12). RESULTS: 200 patients were included in the study. The mean VAS scores for vaginitis symptoms were progressively reduced in both treatment groups at each visit, without significant difference between groups (p>0.05 for each symptom, at each time point). The efficacy of L. plantarum and the reference medicinal product was maintained at follow-up (day 21). The mean concentration of IL-6 decreased from visit 1 to visit 3 in both groups without a significant difference (p>0.05). No adverse events were reported. CONCLUSIONS: L. plantarum P17630 100,000,000 CFU soft vaginal capsules are effective and safe for treating vaginal candidiasis without the concomitant use of an antifungal product, which rules out the risk of antimicrobic resistance. The long-term effect on vaginal microflora may add the possibility of reducing the risk of recurrences.

RESUMO

Vulvovaginal candidiasis (VVC) alongside with antifungal resistance are becoming a major clinical problem in recent years. A prospective study aimed to evaluate the diversity of yeast strains associated with VVC in Tebessa city (northeastern Algeria) and investigate their susceptibility patterns. Over two months, yeasts were isolated on chromogenic medium from twenty-nine non-pregnant women with symptomatic VVC. The isolates were characterized with MALDI-TOF MS and antifungal susceptibility testing was performed for nine antifungal drugs using SensititreTM YeastOneTM YO10. Twenty-nine non-duplicate yeasts were recovered and the mass spectrometry profiles showed reliable scores of which four genera and five different species were identified. Candida albicans accounted for 65.5 % (n = 19) of the total number of isolates, followed by C. glabrata with 20.7% (n = 6). For the remaining non-albicans Candida (NCA) species, Kluyveromyces marxianus with 6.9% (n = 2), Pichia kudriavzevii and Saccharomyces cerevisiae with one isolate each. The antifungal susceptibilities showed wild type MICs of C. albicans to amphotericin B, azoles and echinocandins. In addition, four C. albicans isolates were resistant to flucytosine. For C. glabrata isolates, 100% non-WT phenotype was found for both posaconazole and itraconazole. For the very first time, the obtained outcomes bring out new data concerning the epidemiology of yeasts causing VVC in Algeria and their antimicrobial susceptibility profiles.

RESUMO

Currently, the high incidence of fungal infections among females has resulted in outstanding problems. Candida species is related with multidrug resistance and destitute clinical consequences. Chitosan-albumin derivatives with more stability exhibit innate antifungal and antibacterial effects that boost the activity of the drug without inflammatory impact. The stability and sustained release of Fluconazole in mucosal tissues can be ensured by encapsulating in protein/polysaccharide nanocomposites. Thus, we developed chitosan-albumin nanocomposite (CS-A) loaded with Fluconazole (Flu) antifungals against vaginal candidiasis. Various ratios of CS/Flu (1:1, 1:2, 2:1) were prepared. Thereafter, the CS-A-Flu nanocomposites were qualified and quantified using FT-IR, DLS, TEM, and SEM analytical devices, and the size range from 60 to 100 nm in diameter was attained for the synthesized nanocarriers. Afterward, the antifungal activity, biofilm reduction potency, and cell viability assay were performed for biomedical evaluation of formulations. The minimum inhibitory concentration) and minimum fungicidal concentration on Candida albicans were attained at 125 ng/µL and 150 ng/µL after treatment with a 1:2 (CS/Flu) ratio of CS-A-Flu. The biofilm reduction assay indicated that biofilm formation was between 0.05 and 0.1% for CS-A-Flu at all ratios. The MTT assay also exhibited excellent biocompatibility for samples, about 7 to 14% toxicity on human HGF normal cells. These data have indicated that CS-A-Flu would be a promising candidate against Candida albicans.

RESUMO

Pregnant women with vulvovaginal candidiasis (VVC) may experience adverse pregnancy outcomes such as premature delivery, intrauterine infection, abortion, and neonatal infection. Therefore, finding new treatments for VVC in pregnancy is a public health priority. We aimed to study the adverse consequences of Candida albicans (C. albicans) vaginal infection in pregnant mice and explore the mechanisms by which C. albicans affects macrophages. Our findings contribute to the development of new approaches to treat VVC during pregnancy. We established an animal model of vaginal infection by C. albicans in pregnant mice and observed adverse pregnancy outcomes such as decreased body weight, reduced implantation number, and increased abortion rates. Additionally, we infected mouse macrophage line RAW264.7 cells with C. albicans and established a cell model. We employed RT-qPCR, Western blot, and immunofluorescence staining to verify the changes in the IL-15/STAT5 signaling pathway and the role it played on the M1 polarization of C. albicans-infected macrophages at both the gene and protein levels. Our results indicate that the adverse pregnancy outcomes in VVC may be linked to changes in the IL-15/STAT5 pathway induced by C. albicans, which could impact macrophage M1 polarization.

RESUMO

Vulvovaginal candidiasis (VVC) is a common condition among women. Fluconazole remains the dominant treatment option for VVC. Oteseconazole is a highly selective inhibitor of fungal CYP51. This randomized, double-blinded, phase 3 trial was conducted to evaluate the efficacy and safety of oteseconazole compared with fluconazole in treating severe VVC. Female subjects presenting with vulvovaginal signs and symptoms score of ≥7 and positive Candida infection determined by potassium hydroxide test or Gram staining were randomly assigned to receive oteseconazole (600 mg on D1 and 450 mg on D2) or fluconazole (150 mg on D1 and D4) in a 1:1 ratio. The primary endpoint was the proportion of subjects achieving therapeutic cure [defined as achieving both clinical cure (absence of signs and symptoms of VVC) and mycological cure (negative culture of Candida species)] at D28. A total of 322 subjects were randomized and 321 subjects were treated. At D28, a statistically significantly higher proportion of subjects achieved therapeutic cure in the oteseconazole group than in the fluconazole group (66.88% vs 45.91%; P = 0.0002). Oteseconazole treatment resulted in an increased proportion of subjects achieving mycological cure (82.50% vs 59.12%; P < 0.0001) and clinical cure (71.25% vs 55.97%; P = 0.0046) compared with fluconazole. The incidence of treatment-emergent adverse events was similar between the two groups. No subjects discontinued study treatment or withdrew study due to adverse events. Oteseconazole showed statistically significant and clinically meaningful superiority over fluconazole for the treatment of severe VVC and was generally tolerated.

RESUMO

OBJECTIVE/PURPOSE: Women at reproductive age frequently experience vulvovaginal infections and vaginitis. The most common etiologies are vulvovaginal candidiasis (VVC), bacterial vaginosis (BV), desquamative inflammatory vaginitis/aerobic vaginitis, and trichomoniasis. Various treatment options are available for these infections, such as specific antimicrobial or antiseptic agents. Dequalinium chloride (DQC) is a local antiseptic agent with a broad antimicrobial and antifungal spectrum. Multiple studies suggest that DQC is an efficient treatment for vaginal infections; however, it is not widely recommended as a first-line treatment. This systematic review and meta-analysis aims to evaluate the efficacy of DQC compared with that of standard treatment. METHODS: Our systematic review was conducted according to the PRISMA guidelines. PubMed/MEDLINE, EMBASE, CENTRAL, and clinicaltrials.org were searched to retrieve relevant reports up to October 2022. RESULTS: Four randomized controlled studies and 1 observational study were included in this review. Overall, DQC showed noninferiority to the reference treatments for BV and VVC, and to the evaluated treatment options for desquamative inflammatory vaginitis/aerobic vaginitis. For BV and VVC, this could also be confirmed in a meta-analysis including 3 randomized controlled studies. No serious adverse events were reported in any of these studies. CONCLUSIONS: Dequalinium chloride offers a safe, well-tolerated, and efficient treatment option for vulvovaginal infections of different etiologies. However, further studies are needed to confirm our findings and allow inclusion of DQC as a first-line treatment into guidelines.

RESUMO

Candida causes an estimated half-billion cases of vulvovaginal candidiasis (VVC) every year. VVC is most commonly caused by Candida albicans, which, in this setting, triggers nonprotective neutrophil infiltration, aggressive local inflammation, and symptomatic disease. Despite its prevalence, little is known about the molecular mechanisms underpinning the immunopathology of this fungal infection. In this study, we describe the molecular determinant of VVC immunopathology and a potentially straightforward way to prevent disease. In response to zinc limitation, C. albicans releases a trace mineral binding molecule called Pra1 (pH-regulated antigen). Here, we show that the PRA1 gene is strongly up-regulated during vaginal infections and that its expression positively correlated with proinflammatory cytokine concentrations in women. Genetic deletion of PRA1 prevented vaginal inflammation in mice, and application of a zinc solution down-regulated expression of the gene and also blocked immunopathology. We also show that treatment of women suffering from recurrent VVC with a zinc gel prevented reinfections. We have therefore identified a key mediator of symptomatic VVC, giving us an opportunity to develop a range of preventative measures for combatting this disease.

RESUMO

Candidal infections, particularly vulvovaginal candidiasis (VVC), necessitate effective therapeutic interventions in clinical settings owing to their intricate clinical nature and elusive understanding of their etiological mechanisms. Given the challenges in developing effective antifungal therapies, the strategy of repurposing existing pharmaceuticals has emerged as a promising approach to combat drug-resistant fungi. In this regard, the current study investigates molecular insights on the anti-candidal efficacy of a well-proven anticancer small molecule -3-bromopyruvate (3BP) against three clinically significant VVC causing Candida species viz., C. albicans, C. tropicalis and C. glabrata. Furthermore, the study validates 3BP's therapeutic application by developing it as a vaginal cream for the treatment of VVC. 3BP exhibited phenomenal antifungal efficacy (killing >99%) with minimum inhibitory concentrations (MIC) and minimum fungicidal concentrations (MFC) of 256 µg/mL against all tested Candida spp. Time killing kinetics experiment revealed 20 min as the minimum time required for 3BP at 2XMIC to achieve complete-killing (99.9%) in all Candida strains. Moreover, the ergosterol or sorbitol experiment explicated that the antifungal activity of 3BP does not stem from targeting the cell wall or the membrane component ergosterol. Instead, 3BP was observed to instigate a sequence of pre-apoptotic cascade events, such as phosphatidylserine (PS) externalization, nuclear condensation and ROS accumulations, as evidenced by PI, DAPI and DCFH-DA staining methods. Furthermore, 3BP demonstrated a remarkable efficacy in eradicating mature biofilms of Candida spp., achieving a maximum eradication level of 90%. Toxicity/safety profiling in both in vitro erythrocyte lysis and in vivo Galleria mellonella survival assay authenticated the non-toxic nature of 3BP up to 512 µg/mL. Finally, a vaginal cream formulated with 3BP was found to be effective in VVC-induced female mice model, as it significantly decreasing fungal load and protecting vaginal mucosa. Concomitantly, the present study serves as a clear demonstration of antifungal mechanistic action of anticancer drug -3BP, against Candida species. This finding holds significant potential for mitigating candidal infections, particularly VVC, within healthcare environments.

RESUMO

BACKGROUND: Infectious vaginitis is one of the most prevalent conditions affecting women of reproductive age with significant clinical consequences. Bacterial vaginosis (BV), vulvo-vaginal candidiasis (VVC), and trichomoniasis (TV) are the main etiologies. Unfortunately, there is limited data on the prevalence and associated risk factors, especially in sub-saharan Africa. This study, thus, determined the prevalence and risk factors of infectious vaginitis among women seeking reproductive health services at a Marie-stopes health facility in urban areas of Kampala, Uganda. METHODS: A cross-sectional study with 361 participants was conducted from July to October 2021. Data on risk factors and infection were collected via a structured questionnaire and laboratory analysis of vaginal swabs, respectively, with data analysis performed using Stata version 14.0 college station, Texas 77,845 US. RESULTS: The ages of participants ranged from 18 to 49 years, with a mean age of 29.53 years. Overall, 58.45% were infected, of whom 33.24% had VVC, 24.93% had BV, and 0.28% had TV. Bivariate analysis revealed that women with pruritus (COR: 3.057, 95% CI: 1.940-4.819), pregnancy (COR: 4.914, 95% CI: 1.248-19.36), antibiotic use (COR: 1.592, 95% CI: 1.016-2.494), douching (COR: 1.719, 95% CI: 1.079-2.740), and multiple partners (COR: 1.844, 95% CI: 1.079-2.904) were more likely to have VVC, whereas having higher education status (University; Vocational) (COR: 0.325, 95% CI: 0.134-0.890; COR: 0.345, 95% CI: 0.116-0.905) reduced the risk. On the other hand, women with a smelly discharge (COR: 1.796, 95% CI: 1.036-3.110), IUD use (COR: 1.868, 95% CI: 1.039-3.358), and antibiotic use (COR: 1.731, 95% CI: 1.066-2.811) were more likely to have BV. Multivariable analysis identified pruritus (AOR: 2.861, 95% CI: 1.684-4.863) as the only independent predictor for VVC. CONCLUSION: Results indicate a high prevalence of infection among these women; therefore regular screening and treatment is recommended to curb the high rate of infection. More studies on risk factors of infection are recommended.

RESUMO

In the present work, a series of N-terpenyl organoselenium compounds (CHB1-6) were evaluated for antimycotic activity by determining the minimum inhibitory concentration (MIC) for each compound in fluconazole (FLU)-sensitive (S1) and FLU-resistant (S2) strains of Candida albicans (C. albicans). The most active compounds in the MIC screen were CHB4 and CHB6, which were then evaluated for cytotoxicity in human cervical cancer cells (KB-3-1) and found to be selective for fungi. Next, CHB4 and CHB6 were investigated for skin irritation using a reconstructed 3D human epidermis and both compounds were considered safe to the epidermis. Using a mouse model of vulvovaginal candidiasis (VVC), CHB4 and CHB6 both exhibited antimycotic efficacy by reducing yeast colonization of the vaginal tract, alleviating injury to the vaginal mucosa, and decreasing the abundance of myeloperoxidase (MPO) expression in the tissue, indicating a reduced inflammatory response. In conclusion, CHB4 and CHB6 demonstrate antifungal activity in vitro and in the mouse model of VVC and represent two new promising antifungal agents.
