Bleeding profile satisfaction and pain and ease of placement with levonorgestrel 19.5 mg IUD: findings from the Kyleena® Satisfaction study.

PURPOSE: To investigate bleeding profile satisfaction and pain and ease of placement with levonorgestrel 19.5 mg IUD in routine clinical practice. METHODS: Women who independently chose levonorgestrel 19.5 mg IUD during routine counselling were invited to participate in this prospective, multinational, observational study. Patient-reported pain and clinician-reported ease of placement were assessed. Bleeding profile satisfaction was evaluated at 12 months/premature end of observation. RESULTS: Most participants (77.8%, n = 878/1129) rated levonorgestrel 19.5 mg IUD placement pain as 'none' or 'mild' and most clinicians (91.1%, n = 1029/1129) rated placement as 'easy'. Pain was more often rated higher in nulliparous compared with parous (p < .0001) and younger (<26 years) compared with older participants (p < .0001), although 67.7% and 69.0% of nulliparous and younger participants respectively reported 'none' or 'mild' pain. Bleeding profile satisfaction at 12 months/end of observation was similar in parous (72.9%, n = 318/436) and nulliparous (69.6%, n = 314/451) participants. Most participants irrespective of age reported bleeding profile satisfaction, ranging from 67.8% (n = 206/304) for 18-25 years to 76.5% (n = 218/285) for >35 years. CONCLUSION: We observed high bleeding profile satisfaction regardless of age or parity with levonorgestrel 19.5 mg IUD and confirmed that device placement is easy and associated with no more than mild pain in most cases in routine clinical practice. Real-world evidence from the Kyleena® Satisfaction Study in routine clinical practice shows high bleeding profile satisfaction with levonorgestrel 19.5 mg IUD regardless of age or parity. IUD placement was easy and associated with little to no pain for most women.

Twenty years of research on HPV vaccines based on genetically modified lactic acid bacteria: an overview on the gut-vagina axis.

Most cervical cancer (CxCa) are related to persistent infection with high-risk human papillomavirus (HR-HPV) in the cervical mucosa, suggesting that an induction of mucosal cell-mediated immunity against HR-HPV oncoproteins can be a promising strategy to fight HPV-associated CxCa. From this perspective, many pre-clinical and clinical trials have proved the potential of lactic acid bacteria (LAB) genetically modified to deliver recombinant antigens to induce mucosal, humoral and cellular immunity in the host. Altogether, the outcomes of these studies suggest that there are several key factors to consider that may offer guidance on improvement protein yield and improving immune response. Overall, these findings showed that oral LAB-based mucosal HPV vaccines expressing inducible surface-anchored antigens display a higher potential to induce particularly specific systemic and mucosal cytotoxic cellular immune responses. In this review, we describe all LAB-based HPV vaccine investigations by reviewing databases from international studies between 2000 and 2020. Our aim is to promote the therapeutic HPV vaccines knowledge and to complete the gaps in this field to empower scientists worldwide to make proper decisions regarding the best strategies for the development of therapeutic HPV vaccines.

Clinical and analytical evaluation of the RealTime High Risk HPV assay in Colli-Pee collected first-void urine using the VALHUDES protocol.

OBJECTIVE: Urine self-sampling has gained increasing interest for cervical cancer screening. In contrast to analytical performance, little information is available regarding the clinical accuracy for high-risk Human Papillomavirus (hrHPV) testing on urine. METHODS: VALHUDES is a diagnostic test accuracy study comparing clinical accuracy to detect high-grade cervical precancer (CIN2+) of HPV testing on self-collected compared to clinician-collected samples (NCT03064087). Disease outcome was assessed by colposcopy and histology. The Abbott RealTime High Risk HPV assay performance was evaluated on Colli-Pee collected first-void urine with cervical outcomes as comparator. RESULTS: As no assay cut-off for urine has been clinically validated, we used the predefined cut-off for cervical samples (CN ≤ 32). Using this cut-off, hrHPV testing was similarly sensitive (relative sensitivity 0.95; 95% CI: 0.88-1.01) and specific (relative specificity 1.03; 95% CI: 0.95-1.13) for detection of CIN2+ compared to testing cervical samples. In the subgroup of women of 30 years and older, similar relative sensitivity (0.97; 95% CI: 0.89-1.05) and specificity (1.02; 95% CI: 0.93-1.12) was found. Additionally, an exploratory cut-off (CN ≤ 33.86) was defined which further improved sensitivity and analytical test performance. CONCLUSION: HrHPV-DNA based PCR testing on home-collected first-void urine has similar accuracy for detecting CIN2+ compared to cervical samples taken by a clinician.

Satisfaction and continuation with LNG-IUS 12: findings from the real-world kyleena® satisfaction study.

PURPOSE: The Kyleena® Satisfaction Study (KYSS) aimed to assess satisfaction and continuation with levonorgestrel-releasing intrauterine system (LNG-IUS) 12 (Kyleena®) in routine clinical practice and to evaluate factors that influence satisfaction. MATERIALS AND METHODS: This prospective, observational, multicentre, single-arm cohort study, with 1-year follow-up, was conducted in Belgium, Canada, Germany, Mexico, Norway, Sweden, Spain and the United States from 2017 to 2018. During routine counselling, women who independently selected to use LNG-IUS 12 were invited to participate in the study. KYSS assessed LNG-IUS 12 satisfaction, continuation and safety. RESULTS: Overall, there were 1126 successful LNG-IUS 12 placements, with insertion attempted in 1129 women. Most participants (833/968, 86.1%, 95% CI 83.7-88.2%, with satisfaction outcome data available) reported satisfaction with LNG-IUS 12 at 12 months (or at the final visit if the device was discontinued prematurely). Satisfaction was not associated with age, parity or motivation for choosing LNG-IUS 12. The majority of women (919/1129, 81.4%) chose to continue after 12 months. Discontinuation was not correlated with age or parity. Overall, 191 women (16.9%) reported a treatment-emergent adverse event. CONCLUSIONS: Results from KYSS provide the first real-world evidence assessing LNG-IUS 12, and demonstrate high satisfaction and continuation rates irrespective of age or parity. Clinical trial registration: NCT03182140.

The use of 3 selected lactobacillary strains in vaginal probiotic gel for the treatment of acute Candida vaginitis: a proof-of-concept study.

In vitro studies suggest that certain probiotic bacterial strains have potential activity against opportunistic infections such as Candida. There are few in vivo trials using probiotics as a single treatment for acute Candida vulvovaginitis (CV). In this open-label, proof-of-concept study, selected Lactobacillus strains were tested in women with acute Candida vaginitis. Twenty women diagnosed with proven, symptomatic CV were instructed to administer a vaginal probiotic gel with L. plantarum YUN-V2.0, L. pentosus YUN-V1.0 and L. rhamnosus YUN-S1.0 for 10 consecutive days. Vaginal rinsing fluid, vaginal culture swab and vaginal smear for fresh wet-mount microscopy were collected before and 7, 14 and 28 days after start of treatment. On average, participating women were 39 years old and had an history of 5 vaginal infections of which 95% was CV. Nine women (45%) completed the study without the need of rescue medication. Women who needed rescue treatment experienced twice as much Candida infections in the past. A negative correlation was found between the clinical composite score and the time to use rescue medication (R2 = 0.127). Seventy-four per cent of participants found the study gel comfortable to use, and 42% of all women would use the tested gel again for this indication. Forty-five per cent of women were treated successfully for acute CV with a novel vaginal gel containing 3 selected Lactobacillus strains. Patients needing rescue treatment were suffering from more severe and long-standing disease. These results warrant for further testing of this new product, especially of its potential in cases with mild to moderate severity, as an adjuvant to antimycotics or as a preventive measure in women with recurrent vulvovaginal candidosis.

Insertion experience of women and health care professionals in the Kyleena® Satisfaction Study.

Purpose: The Kyleena® Satisfaction Study (KYSS) is a prospective, observational study conducted to assess satisfaction with LNG-IUS 12 (Kyleena®) in clinical practice and aims to provide adequate information for counselling women on what to expect regarding insertion and satisfaction.Materials and methods: Women deciding to use LNG-IUS 12 during routine counselling were informed of the study and provided informed consent. A baseline analysis was conducted to evaluate demographics, ease of insertion assessed by investigators, pain at insertion rated by women, additional interventions for insertion, and adverse events.Results: 1,110 women (536 parous, 574 nulliparous) had an insertion attempt and were included. Insertion was rated as easy in 494 (92.2%) parous and 516 (89.9%) nulliparous women. Pain was assessed as none or mild by 475 (88.6%) parous and 387 (67.4%) nulliparous women. Additional interventions were not required for most insertions (705; 63.6%). Overall 111 (10.0%) women reported adverse events at the time of baseline analysis.Conclusions: This analysis demonstrates that LNG-IUS 12 insertion is easy and associated with no or mild pain in most women. Additional interventions for insertion are not required in most cases. After 3 months, the number of adverse events is low.Implications: The present baseline analysis of the Kyleena® Satisfaction Study (KYSS) demonstrates that most women rate insertion pain of LNG-IUS 12 as none or mild and clinicians consider insertion easy in the majority of cases.

Treatment Attitudes for Belgian Women With Persistent Trichomonas vaginalis Infection in the VlaResT Study.

BACKGROUND: Because of its increasing prevalence worldwide, its sexual transmissibility and its facilitation of human immunodeficiency virus transmission, Trichomonas vaginalis (TV) infection constitutes an important public health concern. THE AIM OF THE STUDY: While searching for possible resistant TV cases, adequacy of management of TV-infected women was assessed. METHODS: Cervical cytology between July 2007 and July 2014 was tested with TV polymerase chain reaction, and 304 women expressed repeatedly positive results, 718 in total. For each of these positive results, a questionnaire about treatment decisions was sent to the 182 Belgian physicians treating these women. RESULTS: From the 346 returned questionnaires by their physician it was evident that 58.1% of women with repeatedly positive TV had received no treatment. TV was overlooked in 31.5%, and in 17.6% the test result was seen but ignored. Upon seeing the positive result, 23.9% of physicians decided that this finding was not important enough to institute treatment, and/or requested confirmatory tests. Adequate treatment was prescribed in 38.4%. Retreatment after failed therapy was given in only 29.3% of the cases. And 60% of the partners of women with persistent TV infection were not traced, nor treated. CONCLUSION: Most of the repeatedly positive TV infection may not be due to antibiotics resistance. The low awareness, poor attention, failure of contact tracing, and low rates of proper treatment provided by treating physicians question the adequacy of the current management of TV infection and requires renewed education campaigns and increased surveillance.

The efficacy and safety of Tipapkinogen Sovacivec therapeutic HPV vaccine in cervical intraepithelial neoplasia grades 2 and 3: Randomized controlled phase II trial with 2.5 years of follow-up.

BACKGROUND: While prophylactic human papillomavirus (HPV) vaccination exists, women are still developing cervical intraepithelial neoplasia (CIN) grade 2 or 3 for which an immunotherapeutic, non-surgical, approach may be effective. The primary aim was to assess the efficacy of tipapkinogen sovacivec (TS) vaccine in achieving histologic resolution of CIN2/3 associated with high risk (HR) HPV types. METHODS: Women 18 years and older who had confirmed CIN2/3 were enrolled in a randomized, double blind, placebo-controlled phase II trial and assigned to drug in a 2:1 ratio (vaccine:placebo). The primary endpoint occurred at month 6 when the excisional therapy was performed; cytology and HR HPV typing were performed at months 3, 6 and every six months through month 30. The safety population included all patients who received at least one dose of study drug. RESULTS: Of the 129 women randomized to vaccine and 63 to placebo, complete resolution was significantly higher in the vaccine group than placebo for CIN 2/3 regardless of the 13 HR HPV types assayed (24% vs. 10%, p < 0.05); as well as for only CIN 3 also regardless of HR HPV type (21% vs. 0%, p < 0.01). Irrespective of baseline HPV infection, viral DNA clearance was higher in the vaccine group compared to placebo (p < 0.01). The vaccine was well tolerated with the most common adverse events being injection site reactions. CONCLUSIONS: The TS vaccine provides histologic clearance of CIN 2/3 irrespective of HR HPV type in one third of subjects and is generally safe through 30 months.

Development and validation of a new one step Multiplex-PCR assay for the detection of ten Lactobacillus species.

Lactobacillus sp. are well-known colonizers of human mucosa and frequently used as probiotics. Accurate species identification is crucial both for fundamental studies and biotechnology applications; however, it has been thus far challenging. The aim of this work was to develop a one-step multiplex-PCR assay for detection of ten Lactobacillus species (L. jensenii, L. fermentum, L. acidophilus, L. crispatus, L. reuteri, L. iners, L. casei, L. gasseri, L. plantarum, L. rhamnosus) directly in complex bacterial genomic DNA. A multiplex-PCR assay was optimized based on Box-Behnken experimental design, which showed to be efficient for optimization of all crucial reaction components. Nineteen Lactobacillus strains, including six collection strains and thirteen human isolates were used in order to verify the specificity and sensitivity of the assay. In addition, a set of PCR adjuvants was introduced to remove non-specific amplifications and enhance reaction yield. Among them, Triton™ X-100, Tween® 20, BSA, and dithiothreitol showed beneficial effects when compared with other adjuvants. The application of the developed method to samples that resulted from the mixing of DNA from the ten strains, resulted in amplicons of the expected sizes (from about 100 to 1000 bp). The detection limit was 1.25 ng/µl for all species with the exception of L. gasseri (0.31 ng/µl). In order to confirm the method applicability on human samples, ten vaginal fluids were enrolled in this study showing that the method can be successfully used on these biological materials. The proposed multiplex-PCR assay was shown to be selective, sensitive and efficient for detection of ten Lactobacillus species directly in human vaginal samples. This method provides a cost-effective and accessible methodology applicable to the detection of Lactobacillus species to different environments. At the same time, this approach represents a considerable improvement over other PCR-based approaches for identification of these species.

Anti-Candida activity of antidepressants sertraline and fluoxetine: effect upon pre-formed biofilms.

As an opportunistic fungal pathogen Candida spp. has the ability to form biofilms. The most prescribed drugs for Candida infections, azoles, have shown to be less effective when biofilms are present. In addition, increasing treatment costs and the fact that most prescribed antifungal drugs have only fungistatic activity justify the search for new treatment strategies. One promising approach is third generation antidepressants, selective serotonin re-uptake inhibitors (SSRIs), because of their proven antifungal activity against several Candida spp. Thus, the aim of this work was to determine the ability of two commonly used SSRIs, fluoxetine and sertraline, to impair both biofilm metabolic viability and biofilm biomass. The in vitro effect of fluoxetine and sertraline was individually tested against biofilm metabolic viability and biofilm biomass using the MTT assay and the Crystal Violet assay, respectively. For both drugs, a dose-dependent reduction on both biofilm metabolism and biomass was present. At high concentrations, fluoxetine was able to reduce biofilm metabolism by 96% (C. krusei) and biofilm biomass by 82% (C. glabrata), when compared to the control. At similar conditions, sertraline achieved a reduction of 88% on biofilm biomass (C. glabrata) and 90% on biofilm metabolism (C. parapsilosis). Moreover, fluoxetine showed interesting anti-biofilm activity at previously reported planktonic MIC values and even at sub-MIC values. These results reinforce the potential interest of SSRIs as anti-biofilm agents to be study to counteract resistance phenomena on candidosis.

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

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

Sexual behaviour and extra-genital colonisation in women treated for recurrent Candida vulvo-vaginitis.

OBJECTIVE: This study analyses a relation between sexual habits and the presence of Candida in extra-genital locations as well as a potential effect on therapy response. MATERIAL AND METHODS: Candida cultures were obtained from mouth, nose, anus, urine and perineum of 117 women enrolled in a RVVC treatment trial (ReCiDiF). Sexual behaviour and carriage rates of extra-genital Candida of women responding well to treatment were compared to that of non-responders. RESULTS: Most respondents were heterosexual. All but one practiced vaginal sex. Regular receptive oral sex was not related to multiple site colonisation with Candida (OR = 1.27; CI95% 0.36-4.48), nor to non-response to therapy (OR = 1.3; CI 95% 0.41-4.73). Also, masturbation was not related to response to therapy (OR 0.8; CI95% 0.31-1.84), nor was anal sex (OR = 0.54; CI95% 0.11-2.72). CONCLUSION: Neither oral nor casual anal sex, nor masturbation can be held responsible for the association of the multiple site/anal colonisation with Candida and inferior response to fluconazole maintenance therapy. Changing sexual behaviour during fluconazole maintenance treatment for RVVC in otherwise healthy women should not be advocated. Also, treatment of asymptomatic sexual partners of women with RVVC is not recommended.

Deconstructing the genitourinary syndrome of menopause.

The concept of genitourinary syndrome of menopause (GSM) was recently introduced and has been gaining widespread use. While some justifications for its introduction are straightforward, others may be questionable. Numerous unspecific symptoms and signs were included in the definition of the syndrome, but the minimum number required for diagnosis was not established. While the GSM definition is designed to facilitate identifying vulvovaginal and urinary estrogen-deprivation-associated symptoms and signs, several concerns have evolved: (1) the syndrome may result in the underdiagnosis of vulvar and urinary pathology; and (2) serious conditions (e.g., high-grade squamous intraepithelial lesions of the vulva or vulvar intraepithelial neoplasia, differentiated type) may be missed while others may not receive appropriate treatment (e.g., lichen sclerosus, overactive bladder). In addition, the transformation of urogenital symptoms and signs into a syndrome may create an iatrogenization of menopause, which, consequently, can lead to demand for (and offer of) a panacea of treatments. This can be detrimental to the care of women who require focused therapy rather than global treatment addressing a variety of genitourinary conditions, not all of which even require any form of intervention. Women's needs may be better served by having a more precise urogenital diagnosis.

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

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

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

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

Mycoplasma/Ureaplasma infection in pregnancy: to screen or not to screen.

Mycoplasmata have been linked to pregnancy complications and neonatal risk. While formerly a limited number of species could be discovered by cultures, molecular biology nowadays discovers both lower quantities and more diverse species, making us realize that mycoplasmata are ubiquitous in the vaginal milieu and do not always pose a danger for pregnant women. As the meaning of mycoplasmata in pregnancy is not clear to many clinicians, we summarized the current knowledge about the meaning of different kinds of mycoplasmata in pregnancy and discuss the potential benefits and disadvantages of treatment. Currently, there is no general rule to screen and treat for mycoplasmata in pregnancy. New techniques seem to indicate that Ureaplasma parvum (Up), which now can be distinguished from U. urealyticum (Uu), may pose an increased risk for preterm birth and bronchopulmonary disease in the preterm neonate. Mycoplasma hominis (Mh) is related to early miscarriages and midtrimester abortions, especially in the presence of abnormal vaginal flora. Mycoplasma genitalium (Mg) is now recognized as a sexually transmitted infection (STI) that is involved in the causation of cervicitis, pelvic inflammatory disease (PID) in non-pregnant, and preterm birth and miscarriages in pregnant women, irrespective of the presence of concurrent other STIs, like Chlamydia or gonorrhoea. Proper studies to test for efficacy and improved pregnancy outcome are scarce and inconclusive. Azythromycin is the standard treatment now, although, for Mg, this may not be sufficient. The role of clarithromycin in clinical practice still has to be established. There is a stringent need for new studies based on molecular diagnostic techniques and randomized treatment protocols with promising and safe antimicrobials.

Role of Molecular Biology in Diagnosis and Characterization of Vulvo-Vaginitis in Clinical Practice.

The diagnosis of vulvo-vaginal complaints has always been enigmatic in obstetrics and gynecology. Patients with clear, pathognomonic symptoms end up with a proper diagnosis and treatment most of the time, but unfortunately we are now living in a world where women reach out to the Internet and readily get all information as to which disease their symptoms correspond to and also find the appropriate treatment "over-the-counter." Because of this trend, we as specialists are increasingly confronted with patients with complex and combined conditions. At the same time, extremely sensitive and accurate diagnostic tools are now being developed at a rapid pace, allowing the physicians to diagnose vulvo-vaginal disease with a substantially increased precision. Moreover, many of these molecular biology (MB)-based tests have become so common and affordable that self-sampling and self-testing are no longer utopia. On the other hand, too much information that is too readily available and that is too affordable also encompasses pitfalls, leading to gross overtreatment and psychological burden. As experienced caregivers, we should supervise these evolutions, define their place and proper use as diagnostic tools, utilize their potential as ad hoc tools to follow-up treatment efficacy and guide how such tools can be used for responsible self-testing. In the present paper, responding to the need for appropriate, quality assured and accessible tests for vulvo-vaginitis and the huge potential delivered by the rapidly developing MB methods, we recommend the need for a broad and regular discussion forum, composed of both clinical and technical experts and opinion makers, in order to match the needs with the huge opportunities and ideally combine the initiatives and forces into the same direction. This forum should then translate conceived strategies into regularly updated, evidence-based national and international guidelines.

Genital Tract Infections in an Isolated Community: 100 Women of the Príncipe Island.

Objective: To characterize the vaginal microbiome and the rate of sexually transmitted infections (STIs) in the women of Príncipe (São Tomé and Príncipe). Methods: Cross-sectional study of 100 consecutive women, invited for a free appointment and cervical cancer screening. A vaginal slide (wet mount microscopy) and a cervical sample (ThinPrep®) (Pap test, high risk human papillomavirus [HR-HPV], N. gonorrhea [NG], T. vaginalis [TV], and C. trachomatis [CT]) were obtained. Results: TV, NG, CT, and HIV were found in 8.0%, 2.0%, 3.0%, and 2.0%, respectively, and were more prevalent in younger women. HR-HPV was positive in 36.7%; 2 were positive for HPV18, but none for HPV16. Coinfection of HPV with other STIs was 8.3%. Prevalence of abnormal vaginal flora (AVF) was 82.5%, mostly bacterial vaginosis (BV) 54.6%, and moderate/severe aerobic vaginitis (msAV) 25.8%. HR-HPV was not related to BV (p = 0.67). The association of abnormal Pap test with msAV was not significant (p = 0.08). Conclusion: The prevalence of NG, CT, TV, and HR-HPV was according to expected, while that of HR-AVF was higher. The surprisingly low prevalence of HPV16 and HPV18 must be considered in the design of programs for prevention and vaccination; this setting can be useful as a model for postvaccination scenarios.

Development of a microarray-based tool to characterize vaginal bacterial fluctuations and application to a novel antibiotic treatment for bacterial vaginosis.

The healthy vaginal microbiota is generally dominated by lactobacilli that confer antimicrobial protection and play a crucial role in health. Bacterial vaginosis (BV) is the most prevalent lower genital tract infection in women in reproductive age and is characterized by a shift in the relative abundances of Lactobacillus spp. to a greater abundance of strictly anaerobic bacteria. In this study, we designed a new phylogenetic microarray-based tool (VaginArray) that includes 17 probe sets specific for the most representative bacterial groups of the human vaginal ecosystem. This tool was implemented using the ligase detection reaction-universal array (LDR-UA) approach. The entire probe set properly recognized the specific targets and showed an overall sensitivity of 6 to 12 ng per probe. The VaginArray was applied to assess the efficacy of rifaximin vaginal tablets for the treatment of BV, analyzing the vaginal bacterial communities of 22 BV-affected women treated with rifaximin vaginal tablets at a dosage of 25 mg/day for 5 days. Our results showed the ability of rifaximin to reduce the growth of various BV-related bacteria (Atopobium vaginae, Prevotella, Megasphaera, Mobiluncus, and Sneathia spp.), with the highest antibiotic susceptibility for A. vaginae and Sneathia spp. Moreover, we observed an increase of Lactobacillus crispatus levels in the subset of women who maintained remission after 1 month of therapy, opening new perspectives for the treatment of BV.

Effect of short training on vaginal fluid microscopy (wet mount) learning.

OBJECTIVE: Is it feasible to learn the basics of wet mount microscopy of vaginal fluid in 10 hours? MATERIALS AND METHODS: This is a pilot project wherein 6 students with different grades of education were invited for being tested on their ability to read wet mount microscopic slides before and after 10 hours of hands-on training. Microscopy was performed according to a standard protocol (Femicare, Tienen, Belgium). Before and after training, all students had to evaluate a different set of 50 digital slides. Different diagnoses and microscopic patterns had to be scored. κ indices were calculated compared with the expert reading. RESULTS: All readers improved their mean scores significantly, especially for the most important types of altered flora (p < .0001). The mean increase in reading concordance (κ from 0.64 to 0.75) of 1 student with a solid previous experience with microscopy did not reach statistical significance, but the remaining 5 students all improved their scores from poor performance (all κ < 0.20) to moderate (κ = 0.53, n = 1) to good (κ > 0.61, n = 4) concordance. Reading quality improved and reached fair to good concordance on all microscopic items studied, except for the detection of parabasal cells and cytolytic flora. CONCLUSIONS: Although further improvement is still possible, a short training course of 10 hours enables vast improvement on wet mount microscopy accuracy and results in fair to good concordance of the most important variables of the vaginal flora compared to a reference reader.
