Clinical Situation, Species Distribution, and Antibiotic Resistance of Pathogenic Bacteria and Fungi in 626 Cases of Vulvovaginitis in Hangzhou, China.

BACKGROUND: Female vulvovaginitis was one of the most common gynecological diseases. It had a great negative impact on their work and quality of life. This retrospective study evaluated the clinical and laboratory data of patients with vulvovaginitis in Hangzhou, China. To analyze the clinical situation, species distribution and antibiotic resistance of pathogenic fungi and bacteria in 626 cases of vulvovaginitis in Hangzhou. Microorganism culture, identification, and antibiotic susceptibility testing were conducted. The study aimed to provide a theoretical value for an effective treatment of vulvovaginitis. METHODS: In total, 626 outpatients and inpatients diagnosed with vulvovaginitis were selected from January 2018 to January 2023. Data of all the patients were collected from the hospital's electronic medical records. Vaginal secretion was collected for testing and SPSS 25.0 software was used to perform statistical analysis. RESULTS: A total of 626 strains of fungi, Gram-positive, and -negative bacteria were detected. Clinical situations of patients infected with the top five pathogenic fungi and bacteria were analyzed. Pathogenic fungi and bacteria were slightly different in each age group and in each onset time group. The results of antibiotic susceptibility testing showed that the resistance rates of itraconazole and fluconazole were high and Gram- negative and -positive bacteria were multidrug resistant. Gram-negative bacteria were more sensitive to carbenicillins and compound antibiotics, while Gram-positive bacteria were sensitive to rifampicin and daptomycin. MRSA and non vancomycin-resistant strains were detected. CONCLUSIONS: Fungi and bacteria were usually detected as pathogenes in patients with vulvovaginitis in Hangzhou. Some factors, such as age and onset time, often affected the incidence. Pathogenic fungi and bacteria were resistant to some common antibiotics, and clinical treatments should be carried out in a timely and reasonable manner according to the results of antibiotic susceptibility testing.

Efficacy of a Novel Rigenase® and Polyhexanide (Fitostimoline® Septagel) Hydrogel Device for the Treatment of Vulvovaginitis Symptoms: Cross-Sectional Analysis of a National Survey and Prospective Observational Study.

Background and Objectives: Signs and symptoms of vulvovaginitis, especially when recurrent, have a significant impact on a woman's quality of life. The aim of this study was to survey gynecologists about their habits regarding the treatments of the pathology and to evaluate the efficacy of a novel vaginal hydrogel composed of wheat extracts and polyhexanide aimed at reducing vulvovaginitis symptomatology. Materials and Methods: A cross-sectional analysis of a national survey using 155 Italian gynecologists and a prospective, open-label, observational study were carried out in 75 outpatient clinics across Italy. Pre- and postmenopausal women with suspicion of vulvovaginitis due to at least four of the following symptoms (leucoxanthorrhea, bad odor from genitalia, vulvovaginal dryness, petechiae, burning, and pruritus) while waiting for microbiological swab analysis were included and treated with one hydrogel application every 3 days for 1 week. Primary endpoint was the complete resolution of symptomatology. Results: The pre-study survey reported that, for most clinicians, local or oral treatment (65.7% and 82.8%, respectively) with antibiotics or antifungals is used very often. Therefore, we proceeded to carry out an observational study. Overall, 615 (362 of fertile age and 253 in postmenopause) women were included in this study. At the 28th follow-up examination, complete resolution of symptomatology was achieved in 578/615 (94.1%; p < 0.001) within 12.72 ± 6.55 and 13.22 ± 6.33 days for those of fertile age and in postmenopause, respectively (p = 0.342). All of the evaluated symptoms were significantly reduced after treatment (p = 0.001) without differences according to the patient's menopausal status. A slightly significant reduction in Gardnerella Vaginalis (p = 0.040) and Candida Albicans (p = 0.049) was found after treatment. No patient reported side effects, adverse reactions, or discontinued therapy. Conclusions: This pilot study showed that a hydrogel based on Rigenase® (wheat extract) and polyhexanide could be a promising treatment for the relief of vulvovaginitis symptoms. However, these results are limited by the absence of a control group. Additional comparative and randomized controlled trials between the hydrogel and other non-antibiotic devices as well as local antibiotic therapy should be performed to increase the validity of the findings.

Microbiological findings in prepubertal and pubertal girls with vulvovaginitis.

Vulvovaginitis is a common and challenging gynaecological problem in prepubertal and pubertal girls. Such an infection, owing to a wide range of aetiologies, if not responding to hygienic measures, needs further investigation through vaginal cultures, since treatment should be tailored accordingly. This study aimed to investigate the pathogens isolated in prepubertal and pubertal girls with signs and symptoms of vulvovaginitis. A total of 2314 symptomatic girls, 1094 prepubertal and 1220 pubertal, aged 2 to 16 years, were included. Vaginal samples were inoculated on specific culture plates followed by incubation in aerobic, anaerobic or CO2 atmosphere at 37 °C for 24 or 48 h, as appropriate. The identification of the isolated pathogens was carried out using Gram stain, conventional methods and the automated system VITEK 2 (BioMerieux, Marcy l'Etoile, France). Positive cultures were obtained from 587 (53.7%) of prepubertal girls and 926 (75.9%) of pubertal girls. A total of 613 and 984 pathogens were detected in prepubertal and pubertal subjects, respectively. Isolated bacteria included 40.1% and 22.8% Gram-positive cocci, 35.6% and 24.8% Gram-negative rods in the prepubertal and pubertal groups, respectively, with faecal pathogens being the most prevalent. Bacterial vaginosis was diagnosed in 22.8% of prepubertal and 37.9% of pubertal girls. Candida species were isolated mostly in the pubertal girls (14.5%). CONCLUSION: Culture results should be evaluated with caution in children with vulvovaginitis. In the prepubertal girls, the most common isolated pathogens were opportunistic bacteria of faecal origin while girls in late puberty were more susceptible to bacterial vaginosis and vulvovaginal candidiasis. WHAT IS KNOWN: • Vulvovaginitis is the most frequent and challenging reason for referral to paediatric and adolescent gynaecology services. • Microbiological examination can prove to be a significant tool to help diagnosis although results should be evaluated with caution in children. WHAT IS NEW: • Significantly more positive vaginal cultures and pathogens were recorded in symptomatic pubertal girls compared to prepubertal children. • The prevalence of bacterial vaginosis was increased in both prepubertal and pubertal girls with vulvovaginitis although significantly more in girls at puberty.

Clinical Symptoms and Microbiological Findings in Prepubescent Girls with Vulvovaginitis.

BACKGROUND: The diagnosis and treatment of vulvovaginitis in children is poorly managed because it is difficult to determine whether the agent causing vulvovaginal inflammation is a single bacterial species. STUDY OBJECTIVE: This study retrospectively evaluated genital microbiological findings in prepubescent girls with vulvovaginitis and then compared the findings to healthy controls without discharge. METHODS: This was a retrospective case-control study of 483 prepubescent girls aged 2-10 years with vulvovaginitis and 50 age-matched healthy asymptomatic controls. Data were collected at the Pediatric General Outpatient Unit of the Hospital of the Bezmialem Vakif University from December 2015 to March 2021. RESULTS: Of the 483 positive vaginal cultures in the study group, 248 (51.3%) exhibited potential causative agents. Conversely, 8 of 50 (16%) of the vaginal cultures in the control group (P < .001) exhibited potential causative agents. Streptococcus pyogenes was the most frequently detected causative agent of vulvovaginitis in the study group. S. pyogenes was present in specimens from 74 girls (15.8%) with symptoms of vulvovaginitis vs 1 (4.1%) specimen in the control group. Other specific organisms identified in the study group were Escherichia coli (12%), Haemophilus influenzae (5%), Staphylococcus aureus (4.3%), Candida albicans (4.3%), and Streptococcus agalactia (3.3%). CONCLUSIONS: Among prepubescent girls with vulvovaginitis, 51.3% of vaginal cultures exhibited potential causative agents in the study group. Our microbiological data indicated that the most common pathogens were S. pyogenes and E. coli.

Bacterial agents in vulvovaginitis and vaginal discharge: a 10-year retrospective study in the Netherlands.

Vulvovaginitis is a common problem in the GP's practice. Causes are bacterial vaginosis (BV), Candida infection and sexually transmitted infections (STIs). Only if empirical treatment fails, a vaginal swab is sent in for culture and BV detection. However, without culture essential, bacterial pathogens may escape diagnosis. Many molecular BV assays have recently appeared on the marketplace, all quite differing in price and targets. However, for years, the Nugent score has been the gold standard for BV detection. We analysed retrospectively 10 years of microbiology results of vulvovaginal swabs, focusing on less frequently reported bacterial pathogens, and assessed the characteristics of BV diagnostics. Vulvovaginal swabs sent in between 2010 and 2020 from > 11,000 GP patients with vulvovaginitis associated symptoms, but negative STI tests, were analysed. First cultures and repeat cultures after at least 6 months were included in four age groups: < 12, 12-17, 18-51 and > 51 years. Candida species and BV were most frequently found, with the highest prevalence in premenopausal women. Haemophilus influenzae, beta-haemolytic streptococci, Streptococcus pneumoniae and Staphylococcus aureus were isolated in 5.6% of all cultures, with the highest percentages in children and postmenopausal women. If empirical treatment of vulvovaginitis fails, bacterial culture should be performed to detect all potentially pathogenic microorganisms to obtain a higher rate of successful diagnosis and treatment, avoiding unnecessary antimicrobial use and costs. For BV detection, molecular testing may seem attractive, but Nugent scoring still remains the low-cost gold standard. We recommend incorporating the above in the appropriate guidelines.

STROBE-sequencing analysis of the vaginal microecology of 4- to 6-year-old girls in Southwest China.

ABSTRACT: We investigated the vaginal flora diversity of preschool-aged (ie, 4-6-year-old) girls in southwest China.Fourteen preschool-aged girls were enrolled in this study. The statuses and differences in their vaginal flora were evaluated by Gram staining, bacterial culturing, and sequencing analysis.Gram staining and microbial culturing showed that the main vaginal flora of the preschool-aged girls were Gram-negative bacilli, whereas the main vaginal flora of healthy adult controls were large Gram-positive bacilli such as Lactobacillus crispatus. Shannon and Simpson indexes indicated that the bacterial diversity tended to decrease with age. The species abundance heat map showed that the vaginal microecology of the girls differed slightly at different ages but mainly comprised Pseudomonas, Methylobacterium, Sphingomona,s and Escherichia. The functional abundance heat map indicated that the bacterial functions increased with age.The vaginal microecology of preschool-aged girls differs from that of adults. A comprehensive understanding of the vaginal flora diversity of preschool-aged girls will aid in clinically diagnosing vulvovaginitis in preschool-aged girls.

Characteristics of the vaginal microbiomes in prepubertal girls with and without vulvovaginitis.

The present study focused on the characteristics of the vaginal microbiomes in prepubertal girls with and without vulvovaginitis. We collected 24 vaginal samples and 16 fecal samples from 10 girls aged 3-9 years with vulvovaginitis and 16 healthy girls of the same age. The samples were divided into three groups: fecal swabs from healthy controls (HF), vaginal swabs from healthy controls (HVS), and vaginal swabs from girls with vulvovaginitis (VVS). Sequencing of the V3-V4 region of the 16S rDNA gene was performed with the NovaSeq PE250 platform to reveal the vaginal microbial community structure in healthy prepubertal girls and vulvovaginitis-associated microbiota. The intestinal microbiomes of healthy children were also analyzed for comparison. This study revealed that the healthy vaginal tract in prepubertal girls was dominated by Prevotella, Porphyromonas, Ezakiella, and Peptoniphilus species, with a high diversity of microbiota. The vulvovaginitis-associated microbiota were dominated by Streptococcus, Prevotella, Haemophilus, and Granulicatella, with lower diversity than that in healthy girls. Furthermore, the compositions of the vaginal and intestinal microbiomes were completely different. ANOSIM, MRPP, Adonis, and AMOVA were used to analyze the beta diversity, and the results showed that there were significant differences in the microbial communities among the three groups. Lactobacillus deficiency and high bacterial diversity were characteristics of the vaginal microbiome in healthy prepubertal girls; this is inconsistent with that in reproductive-age women. The vulvovaginitis-associated vaginal microbiota differed dramatically from normal microbiota, and the main causative agents were not fecal in origin.

Comparison of Short-Duration and Chronic Premenarchal Vulvar Complaints.

STUDY OBJECTIVE: To compare clinical characteristics, treatment histories, and microbiology of premenarchal girls who presented to a pediatric gynecology specialty clinic with short-duration and chronic vulvar symptoms. DESIGN: Retrospective cohort study. SETTING: Pediatric and adolescent gynecology clinic at a tertiary care children's hospital. PARTICIPANTS: One hundred eighty-two premenarchal patients ages 2-14 years who presented to a pediatric gynecology specialty clinic with vulvar complaints and who were evaluated with a yeast and/or bacterial culture. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Chronic and short-duration vulvar symptoms, microbiology, and diagnosis. RESULTS: Patients with chronic symptoms were more likely to present with itching (59/102 (57.8%) vs 34/80 (42.5%); P = .04), redness or rash (53/102 (52.0%) vs 22/80 (27.5%); P = .0009), and discomfort (59/102 (57.8%) vs 30/80 (37.5%); P = .006), compared with patients with short-duration symptoms. Overall, 44.5% of patients had a history of antifungal treatment, with a greater proportion of patients with chronic symptoms having received antifungal treatment compared with those with short-duration symptoms (53/102 (52.0%) vs 28/80 (35.0%); P = .02). Despite a history of antifungal treatment in nearly half of the patients, Candida albicans was isolated in only 3/144 (2.1%) yeast cultures. Bacterial vulvar cultures were positive in 75/159 (47.2%), and there was no difference among the symptom duration groups (38/71 (53.5%) vs 37/88 (42.1%); P = .15). CONCLUSION: Vulvovaginitis is a common gynecological diagnosis among premenarchal girls with short-duration and chronic vulvar symptoms. Regardless of symptom duration, yeast cultures are rarely positive. Antifungal treatment should be avoided in toilet-trained prepubertal girls.

Evaluation of vulvovaginitis in the adolescent patient.

Vulvovaginitis, referring to inflammation of the vulva and vagina, is a commonly reported concern among adolescents and young women presenting for gynecologic care. Symptoms of vulvovaginitis may include vaginal discharge, odor, itching, pain, dysuria, skin irritation, burning, and dyspareunia. Vulvovaginitis may result from infectious or non-infectious causes. Bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis represent the three most common infectious causes of vulvovaginitis in adolescents and young adults. Additionally, non-infectious causes such as the presence of a foreign body in the vagina, chemical irritants, douching, and poor hygiene may also lead to symptoms of vulvovaginitis. A thorough history in combination with the appropriate physical examination and laboratory evaluation is necessary to identify the cause of a patient's symptoms. Importantly, adolescent patients should be given the opportunity to speak privately with the provider without a parent or guardian present in the room, particularly when gathering the sexual history. Appropriate anticipatory guidance and counseling should be provided once a diagnosis has been made, and prevention of future episodes of vulvovaginitis should be discussed.

Prepubertal Vulvovaginitis.

Vulvovaginitis is a common gynecologic complaint in prepubertal girls. It typically presents with complaints of vulvovaginal itching, burning, irritation, discharge, or skin changes. Prepubertal females have anatomic, physiological, and behavioral factors that most often contribute to the development of symptoms. Careful attention to history and associated complaints will direct evaluation, diagnosis, and treatment. Most cases are nonspecific in origin and treatment includes counseling to patients and parents on hygiene and voiding techniques. Antibiotic treatment for specific pathogens may be indicated. Other less common causes include foreign bodies and lichen sclerosus.

In vitro antifungal resistance profile of Candida strains isolated from Saudi women suffering from vulvovaginitis.

BACKGROUND: Vulvovaginal candidiasis (VVC) represents a universal health hazard that contributes to significant morbidity in women. Resistance of Candida to antifungal therapy has been reported as a public health problem. So, the objective of our current study is to detect resistance profile of different candidal strains. METHODS: In this study, isolated Candida strains were identified by conventional methods, confirmed by internal transcribed spacer (ITS) sequencing, and phylogenetically analyzed with reference strains in GenBank. Also, sensitivity of different Candida strains to common antifungal agents was evaluated by disc diffusion method. RESULTS: Candida albicans was identified as the most frequent strain (63%) followed by non-albicans strains, such as C. glabrata (20%), C. tropicalis (13%), and C. krusei (4%). Sensitivity of Candida strains (C. albicans, C. tropicalis and C. glabrata) to commonly used antifungal agents was evaluated through the disc diffusion method. C. glabrata was the most resistant strain and considered to be a multidrug-resistant pathogen, while both, C. albicans and C. tropicalis showed high susceptibility to terbinafine. In contrast, C. albicans showed resistance to fluconazole, clotrimazole, and nystatin, while C. tropicalis, considered as the most sensitive strain, was susceptible to all the antifungal agents tested except nystatin. Terbinafine was the most effective antifungal agent against both C. tropicalis and C. albicans, and hence its minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) for C. albicans and C. tropicalis were evaluated. MICs of terbinafine against C. albicans and C. tropicalis were 5 µg/ml and 2.5 µg/ml, while their MFCs were 10 µg/ml and 5 µg/ml, respectively. CONCLUSION: The emergence of resistant Candida strains necessitates conduction of the antifungal susceptibility test prior to deciding the medication regime.

Clinical and Microbiological Findings of Vulvovaginitis in Prepubertal Girls.

STUDY OBJECTIVE: To evaluate genital microbiological findings in prepubertal girls with vulvovaginitis and in healthy controls. DESIGN: Prospective case-control study. SETTING: Pediatric Outpatient unit of the Department of Pediatrics of the Hospital of the Lithuanian University of Health Sciences Kauno Klinikos from November 2014 to May 2017. PARTICIPANTS: Fifty-two prepubertal girls aged 1-9 years diagnosed with vulvovaginitis, and 42 age-matched healthy controls. INTERVENTIONS AND MAIN OUTCOME MEASURES: Samples for microbiological culture were collected using sterile cotton swabs from the introitus and the lower third of the vagina from all study participants. Microbiological findings were analyzed according to bacteria type and intensity of growth. RESULTS: Most of the vaginal microbiological swab results were positive for bacterial growth: 47 (90.4%) and 34 (80.9%) were similar in the study and control groups, respectively (P = .24). Sixteen (30.8%) and 9 (21.4%) of the microbiological traits results in the case and control groups, respectively, were regarded as potential causative agents (P = .27). Streptococcus pyogenes was the most frequent pathogen in the study group (P = .03); all other microorganisms detected as either a pure or dominant growth in the control group, were considered opportunistic. CONCLUSIONS: Vaginal bacterial culture results were positive in prepubertal girls with vulvovaginitis and in healthy controls. Nonspecific vulvovaginitis without a dominant/isolated pathogen was seen to be more common than vulvovaginitis with a potential causative agent. Clinical symptoms were more frequent among girls when the potential infectious agent was identified.

Estimated burden of fungal infections in Sweden.

The aim of this study was to estimate the annual burden of fungal infections in Sweden using data mainly from 2016. Data on specific populations were obtained from Swedish national data registries. Annual incidence and prevalence of fungal disease was calculated based on epidemiological studies. Data on infections due to Cryptococcus sp., Mucorales, Histoplasma capsulatum, Coccidioides immitis and Pneumocystis jirovecii were retrieved from Karolinska University Laboratory and covers only 25% of Swedish population. In 2016, the population of Sweden was 9 995 153 (49.8% female). The overall burden of fungal infections was 1 713 385 (17 142/100 000). Superficial fungal infections affect 1 429 307 people (1429/100 000) based on Global Burden of Disease 14.3% prevalence. Total serious fungal infection burden was 284 174 (2843/100 000) in 2016. Recurrent Candida vulvovaginitis is common; assuming a 6% prevalence in women. Prevalence of allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation were estimated to be 20 095 and 26 387, respectively. Similarly, chronic pulmonary aspergillosis was estimated to affect 490 patients after tuberculosis, sarcoidosis and other conditions. Candidemia incidence was estimated to be 500 in 2016 (4.7/100 000) and invasive aspergillosis 295 (3.0/100 000). In Stockholm area, Mucorales were reported in three patients in 2015, while Cryptococcus spp. were reported in two patients. In 2016, there were 297 patients PCR positive for P jirovecii. The present study shows that the overall burden of fungal infections in Sweden is high and affects 17% of the population. The morbidity, mortality and the healthcare-related costs due to fungal infections warrant further studies.

Streptococcal toxic shock syndrome following group A streptococcal vulvovaginitis in a breastfeeding woman.

Streptococcal toxic shock syndrome (STSS) is a systemic, life-threatening illness usually caused by invasive respiratory tract or skin and soft tissue infections of Streptococcus pyogenes (group A streptococcus, GAS). We report the case of an adult woman with lactational amenorrhea and GAS vulvovaginitis progressing to STSS. She was admitted to our hospital because of fever, lethargy, and a 2-week history of vaginal discharge; she also had hypotension and multiple organ failure. Blood and urine cultures yielded gram-positive cocci and GAS. After 14 days of antimicrobial therapy, she fully recovered without any complications. The vulvovaginitis was most likely the portal of entry for GAS, which is rarely recognized as a causative pathogen of vulvovaginitis. Lactational amenorrhea is thought to be a risk factor for GAS vulvovaginitis. It is important for clinicians to recognize the possibility of GAS vulvovaginitis in breastfeeding women with vaginal symptoms and consider the necessity of prompt antibiotic treatment.

Association of Ureaplasma diversum with reproductive disease in cattle.

Aims: To examine the association between the detection of Ureaplasma diversum in vaginal swabs from dairy cows in north western Spain with the diagnosis of granular vulvovaginitis (GVV) and reproductive performance, and the association with subclinical endometritis (SE) in slaughterhouse material. The presence of this microorganism in cases of abortion was also investigated. Methods: From 106 dairy farms in the province of Lugo, 40 herds were randomly selected. Vaginal swabs were obtained from 10 randomly selected cows per farm, then pooled for analysis to detect the presence of U. diversum by quantitative real-time PCR (qPCR). In five of these herds samples from the 10 animals were individually tested for U. diversum, and the presence of GVV lesions and their reproductive efficiency (number of inseminations to achieve pregnancy over two subsequent pregnancies) were determined. Vaginal swabs from uteri of cattle obtained at a slaughterhouse (n = 100) were tested for U. diversum and the presence of SE, defined as >5% polymorphonuclear cells in cytobrush smears, was determined. Sixteen farms with abortion problems submitted samples for culture and PCR testing including for U. diversum. Results: Of the 40 herds, 39 (98%) tested positive for U. diversum. On the five farms, 25/50 (50%) cows tested positive for U. diversum, and more cows with GGV-lesions (16/25; 64%) tested positive than cows without lesions (9/25; 36%) (p = 0.047). There were more cows with poor reproductive efficacy that tested positive (8/11; 57%) than tested negative (3/17; 18%) for U. diversum (p = 0.029). Of the 100 uteri, five tested positive for U. diversum and there were more uteri with SE that tested positive (3/19; 16%) than uteri without SE (2/81; 2%) (p = 0.036). U. diversum was also diagnosed in 4/16 farms with abortion problems and liver appeared to be the best tissue for detecting U. diversum DNA in the fetuses analysed. Conclusions and Clinical Relevance: Infection with U. diversum was present in most of herds investigated and it was statistically associated with GVV, SE and poor reproductive performance. It was also detected in abortions and the liver may also be an additional tissue to be considered in the diagnosis of U. diversum abortion by PCR. The possible association with different diseases in the same area suggests that different presentations should be considered when studying the implications of U. diversum on the reproductive diseases of cattle.

Erosive Vulvovaginitis Associated With Borrelia burgdorferi Infection.

We describe a case of acute erosive vulvovaginitis accompanying Borrelia burgdorferi infection. The patient is a 57-year-old woman previously diagnosed with Lyme disease who presented with a painful erosive genital lesion. At the time of the outbreak, she was being treated with oral antibiotics, and she tested serologically positive for B burgdorferi and serologically negative for syphilis. Histological examination of biopsy tissue from the lesion was not characteristic of dermatopathological patterns typical of erosive vulvar conditions. Dieterle-stained biopsy sections revealed visible spirochetes throughout the stratum spinosum and stratum basale, and anti- B burgdorferi immunostaining was positive. Motile spirochetes were observed by darkfield microscopy and cultured in Barbour-Stoner-Kelly-complete medium inoculated with skin scrapings from the lesion. Cultured spirochetes were identified genetically as B burgdorferi sensu stricto by polymerase chain reaction, while polymerase chain reaction amplification of treponemal gene targets was negative. The condition resolved after treatment with additional systemic antibiotic therapy and topical antibiotics. In cases of genital ulceration that have no identifiable etiology, the possibility of B burgdorferi spirochetal infection should be considered.

Vaginal yeast colonisation: From a potential harmless condition to clinical implications and management approaches-A literature review.

Vaginal yeast colonisation is a common clinical condition in premenopausal women. The potential pathogenicity and the circumstances under which it could evolve into infection are not fully clarified. Extensive review the literature regarding the definition of the vaginal yeast colonisation, its demographic features and causes as well as the risk factors favouring infection along with the necessity of treatment. Databases, namely PubMed-MEDLINE, Google Scholar, the University College London databases, e-journals, e-books and official Health Organisations websites were extensively searched in English, French, German and Greek language with no restriction in the type of publications during the last thirty years. In healthy women, vaginal yeast colonisation is an asymptomatic state with Candida albicans being the most prevalent species. Pregnant, HIV-positive and diabetic hosts are at higher risk. Other risk factors include oral contraceptives, hormonal replacement therapy and previous antibiotic use. Colonisation does not necessitate therapeutic intervention when asymptomatic. Prophylactic therapy during the third trimester of pregnancy is often recommended for reducing the risk of neonatal candidiasis. The distinction between commensalism and vaginitis is often complicated. Clinicians should be aware of the clinical context in order to decide the indicated therapeutic approach.

A Novel 1,3-Beta-d-Glucan Inhibitor, Ibrexafungerp (Formerly SCY-078), Shows Potent Activity in the Lower pH Environment of Vulvovaginitis.

Ibrexafungerp (IBX) (formerly SCY-078) is a novel glucan synthase inhibitor whose oral availability is being evaluated for efficacy against vulvovaginal candidiasis (VVC). Bioavailability and in vitro activity are important efficacy indicators, but accepted susceptibility methods do not always accurately predict activity in an acidic environment, such as the vagina. Studies were 3-fold, as follows: (i) pharmacokinetic study following oral administration in a murine model; (ii) susceptibility testing of isolates from a phase 2 VVC clinical trial by CLSI M27-A4 methodology; and (iii) susceptibility testing of Candida albicans and Candida glabrata isolates obtained from this trial group in RPMI 1640 adjusted to 3 different pH values, 7.0, 5.72, and 4.5, compared to susceptibility testing for micafungin and fluconazole. IBX readily accumulated in vaginal tissues and secretions following oral administration. Potent in vitro activity was demonstrated against Candida strains obtained at baseline and end of study visits. Moreover, the geometric mean (GM) values for IBX at pH 4.5 were dramatically lower than those at pH 7.0 and 5.72. The MIC90 values of micafungin remained the same regardless of pH value, while those of fluconazole tended to increase with lower pH values. IBX is able to reach target tissues following oral administration at pharmacologically meaningful levels. IBX demonstrated potent in vitro activity, with no development of resistance, following repeated exposure over the course of the clinical trial. Importantly, activity of IBX in an acidic medium suggests a therapeutic advantage of this novel antifungal in the treatment of vaginal Candida infections.
