New developments in the management of vulvovaginal atrophy: a comprehensive overview.

INTRODUCTION: Proper recognition and individualized therapy of vulvovaginal atrophy (VVA) is paramount. AREAS COVERED: Assessment of VVA should be performed using several questionnaires in combination with wet mount microscopy to determine Vaginal Cell Maturation Index (VCMI) and infections. PubMed searches were carried out between 1 march 2022 and 15 October 2022.Low dose vaginal estriol seems safe, efficient, and could be used in patients with contraindications for steroid hormones such as women with a history of breast cancer, and should therefore be considered as first choice hormonal treatment, when non-hormonal treatments fail. New estrogens, androgens, and several Selective Estrogen Receptor Modulators (SERMs) are being developed and tested. Intravaginal Hyaluronic Acid (HA) or Vit D can help women who can't or don't want to use hormones. EXPERT OPINION: Proper treatment is not possible without a correct and full diagnosis, including microscopy of the vaginal fluid. Low dose vaginal estrogen treatment, especially with estriol, is very efficient and is preferred in most women with VVA. Oral ospemifene and vaginal dihydroepiandrosterone (DHEA) are now considered efficient and safe alternative therapies for VVA. More safety data are waited for several SERMs and for a newly introduced estrogen: estetrol (E4), although so far no major side effects were seen from these drugs. Indications for laser treatments are questionable.

Does a Caesarean Section Scar Affect Placental Volume, Vascularity and Localization?

Caesarean section is associated with an increased risk of abnormal placental implantation and adverse pregnancy outcomes in subsequent pregnancies. Besides the placenta accrete spectrum, only a few of the previous studies focused on other placental development alterations in the scarred uterus. We assessed placental development deviations in the uterus with a Caesarean section scar by evaluating placental volume (PV) and vascular flow indexes. From 1 January 2021 until 31 March 2022, placental volumes and vascularization indexes (VI, FI, VFI) were prospectively measured by 3D power Doppler and VOCAL techniques in 221 patients attending the first trimester screening program. We also calculated the placental quotient to standardize PV to the gestational age. No statistically significant differences in the values of placental volume, placental quotient and placental vascularization indexes were detected between women with previous Caesarean section delivery or women with vaginal delivery. FI was significantly lower in nulliparous in the first trimester. The results of our study suggest that 3D placental evaluation was not able to detect placental development alteration in the uterus with a Caesarean section scar. Future research needs to verify whether 3D power Doppler and Vocal techniques can provide more information if used in an earlier gestational age.

Literature Review of Cervical Regeneration after Loop Electrosurgical Excision Procedure, and Study Project (CeVaLEP) Proposal.

OBJECTIVE: To compile existing knowledge on the level of cervical regeneration (detected by ultrasound) after loop electrosurgical excision procedure (LEEP) and to suggest research protocol for further studies. METHODS: We conducted a literature search of Medline, Web of Science, Scopus, and Cochrane databases using the keywords "cervix" and "regeneration" without year restrictions. Our eligibility criteria included studies that analysed cervical volume and length regeneration using ultrasound. A literature review was conducted following PRISMA guidelines and registered in PROSPERO (reg. no. CRD42021264062). Information about the studies was extracted from each analysed study on an Excel datasheet and the average regeneration with standard deviation was calculated. All included studies' possible biases were assessed by the National Institutes of Health's (NIH) quality assessment tool. RESULTS: The literature search identified 802 papers and four trials (n = 309) that met our criteria. They investigated cervical length and volume regeneration after LEEP using ultrasound, concluding that there is a profound regeneration deficit. Average cervical length regeneration after 6 months was 83.4% (±10.8%) and volume regeneration was 87.4% (±6.1%). All analysed studies had their biases; therefore, based on the conducted studies' protocols, we present a CeVaLEP research protocol to guide high-quality studies. CONCLUSION: After LEEP, there is a cervical regeneration deficit. There is a lack of high-quality studies that assess cervical volume regeneration and its relation to obstetrical outcomes. There is a gap in the field and more research is needed to define the prenatal risks related to cervical regeneration.

Lab-Based Retrospective 10-Year Analysis Shows Seasonal Variation of Vaginal Candida Infection Rates in Belgium.

Candida vulvovaginitis is a frequent condition, and although several risk factors are known, its behavior is still enigmatic. The seasonal influence of climate conditions and living habits on its prevalence was studied. In a retrospective lab-based cohort over 10 years, we studied the prevalence of Candida in 12,941 vaginal cultures taken from women attending a vulvovaginitis clinic. The prevalence of non-albicans and albicans species were compared per month to detect differences in positivity rates in summer versus winter months. Chi-square and chi-square for trend were used. Of the 2109 (16.3%) Candida spp. positive swabs, 201 (1.0%) revealed non-albicans species, varying between 1.0% and 2.0% per month, but without significant monthly differences. Over the 10 years, compared to other months, vaginal Candida was more frequent in June (19.0%, p = 0.008) and less frequent in December (14.5%, p = 0.04). The Candida prevalence was 15.5% in summer (June/July/August) versus 14.0% in the winter (Dec/Jan/Feb, p = 0.04). Change in temperature, dietary habits, and bodily adaptations due to increased amount of sunlight were discussed as potential pathophysiological mechanisms to explain the excess of Candida in summertime. Further confirmatory research would be beneficial. Women at risk for Candida vulvovaginitis should pay more attention to living habits in summertime to avoid recurrences.

Aerobic Vaginitis Diagnosis Criteria Combining Gram Stain with Clinical Features: An Establishment and Prospective Validation Study.

Wet-mount microscopy aerobic vaginitis (AV) diagnostic criteria need phase-contrast microscopy and keen microscopists, and the preservation of saline smears is less common in clinical practice. This research work developed new AV diagnostic criteria that combine Gram stain with clinical features. We enrolled 325 AV patients and 325 controls as a study population to develop new AV diagnostic criteria. Then, an independent group, which included 500 women, was used as a validation population. AV-related microscopic findings on Gram-stained and wet-mount smears from the same participants were compared. The accuracy of bacterial indicators from the two methods was verified by bacterial 16S rRNA V4 sequencing (n = 240). Logistic regression was used to analyse AV-related clinical features. The screened clinical features were combined with Gram-stain microscopic indicators to establish new AV diagnostic criteria. There were no significant differences in the leukocyte counts or the parabasal epitheliocytes (PBC) proportion between the Gram-stain and wet-mount methods (400×). Gram stain (1000×) satisfied the ability to identify bacteria as verified by 16S rRNA sequencing but failed to identify toxic leukocytes. The new criteria included: Lactobacillary grades (LBG) and background flora (Gram stain, 1000×), leukocytes count and PBC proportion (Gram stain, 400×), and clinical features (vaginal pH > 4.5, vagina hyperemia, and yellow discharge). These criteria satisfied the accuracy and reliability for AV diagnosis (Se = 86.79%, Sp = 95.97%, and Kendall's W value = 0.899) in perspective validation. In summary, we proposed an alternative and valuable AV diagnostic criteria based on the Gram stain, which can make it possible to diagnose common vaginitis like AV, BV, VVC, and mixed infections on the same smear and can be available for artificial intelligence diagnosis in the future.

Sperm quality and absence of SARS-CoV-2 RNA in semen after COVID-19 infection: a prospective, observational study and validation of the SpermCOVID test.

OBJECTIVE: To study the contagiousness of sperm and its influence on fertility after recovery from COVID-19 infection. DESIGN: Prospective cohort study. SETTING: University medical center. PATIENT(S): One hundred twenty Belgian men who had recovered from proven COVID-19 infection. INTERVENTION(S): No intervention was performed. MAIN OUTCOME MEASURE(S): Semen quality was assessed using the World Health Organisation criteria. DNA damage to sperm cells was assessed by quantifying the DNA fragmentation index and the high density stainability. Finally antibodies against SARS-CoV2 spike-1 antigen, nuclear and S1-receptor binding domain were measured by Elisa and chemilumenscent microparticle immunoassays, respectively. RESULT(S): SARS-CoV-2 RNA was not detected in semen during the period shortly after infection nor at a later time. Mean progressive motility was reduced in 60% of men tested shortly (<1 month) after COVID-19 infection, 37% of men tested 1 to 2 months after COVID-19 infection, and 28% of men tested >2 months after COVID-19 infection. Mean sperm count was reduced in 37% of men tested shortly (<1 month) after COVID-19 infection, 29% of men tested 1 to 2 months after COVID-19 infection, and 6% of men tested >2 months after COVID-19 infection. The severity of COVID-19 infection and the presence of fever were not correlated with sperm characteristics, but there were strong correlations between sperm abnormalities and the titers of SARS-CoV-2 IgG antibody against spike 1 and the receptor- binding domain of spike 1, but not against nucleotide, in serum. High levels of antisperm antibodies developed in three men (2.5%). CONCLUSION(S): Semen is not infectious with SARS-CoV-2 at 1 week or more after COVID-19 infection (mean, 53 days). However, couples with a desire for pregnancy should be warned that sperm quality after COVID-19 infection can be suboptimal. The estimated recovery time is 3 months, but further follow-up studies are under way to confirm this and to determine if permanent damage occurred in a minority of men.

ISIDOG Consensus Guidelines on COVID-19 Vaccination for Women before, during and after Pregnancy.

INTRODUCTION: Sars-CoV-2 infection poses particular problems in pregnancy, as the infection more frequently causes severe complications than in unaffected pregnant women or nonpregnant women with SARS-CoV-2 infection. Now that vaccination is available and rapidly being implemented worldwide, the question arises whether pregnant women should be vaccinated, and if so, whether they should receive priority. METHODS: Available scientific data and available guidelines about vaccination against SARS-CoV-2 were collected by the Guideline Committee of the International Society of Infectious Diseases in Obstetrics and Gynecology (ISIDOG) and were analyzed, discussed and summarized as guidelines for healthcare workers caring for pregnant women. Concluding statements were graded according to the Oxford evidence-based medicine grading system. RESULTS: There is evidence to consider pregnancy as a risk factor for serious complications of COVID-19 infection, even in the absence of additional risk factors, such as hypertension, diabetes and obesity which increase these risks even more in pregnancy. Currently available data slightly favor mRNA-based vaccines above vector-based vaccines during pregnancy and breastfeeding, until more safety data become available. CONCLUSION: ISIDOG advises policy makers and societies to prioritize pregnant women to receive vaccination against SARS-CoV-2 and favor the mRNA vaccines until further safety information becomes available.

Aerobic Vaginitis-Underestimated Risk Factor for Cervical Intraepithelial Neoplasia.

The aim of this study is to analyse the association between vaginal microbiota and the histological finding of CIN. From July 2016 until June 2017, we included 110 consecutive patients with abnormal cervical cytology results referred for colposcopy to Riga East Clinical University Hospital Outpatient department in the study group. 118 women without cervical pathology were chosen as controls. Certified colposcopists performed interviews, gynaecological examinations and colposcopies for all participants. Material from the upper vaginal fornix was taken for pH measurement and wet-mount microscopy. Cervical biopsy samples were taken from all subjects in the study group and in case of a visual suspicion for CIN in the control group. Cervical pathology was more often associated with smoking (34.6% vs. 11.0%, p < 0.0001), low education level (47.2% vs. 25.5%, p = 0.001), increased vaginal pH (48.2% vs. 25.4%, p < 0.0001), abnormal vaginal microbiota (50% vs. 31.4%, p = 0.004) and moderate to severe aerobic vaginitis (msAV) (13.6% vs. 5.9%, p = 0.049) compared to controls. The most important independent risk factors associated with CIN2+ were smoking (OR 3.04 (95% CI 1.37-6.76), p = 0.006) and msAV (OR 3.18 (95% CI 1.13-8.93), p = 0.028). Bacterial vaginosis (BV) was found more often in CIN1 patients (8/31, 25.8%, p = 0.009) compared with healthy controls (8/118, 6.8%), or CIN2+ cases (8/79, 10.1%). In the current study msAV and smoking were the most significant factors in the development of CIN in HPV-infected women, especially high grade CIN. We suggest that AV changes are probably more important than the presence of BV in the pathogenesis of CIN and progression to cervix cancer and should not be ignored during the evaluation of the vaginal microbiota.

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.

The Dwindling Microbiota of Aerobic Vaginitis, an Inflammatory State Enriched in Pathobionts with Limited TLR Stimulation.

While bacterial vaginosis (BV) is a well-known type of vaginal dysbiosis, aerobic vaginitis (AV) is an inflammatory condition that remains understudied and under-recognised. It predisposes women to serious complications including urogenital infections and pregnancy problems. Here, we investigated the bacterial community in AV to explore its possible role in AV pathogenesis. We collected vaginal lavage fluid samples of women (n = 58) classified by wet-mount microscopy as suffering from AV or BV and included an asymptomatic reference group without signs of AV or BV. AV samples showed reduced absolute abundances of bacteria in general and specifically of lactobacilli by qPCR, but 16S rRNA gene sequencing and amplicon sequence variant analysis revealed that Lactobacillus remained the dominant taxon in 25% of the AV samples studied. The other AV samples showed high relative abundances of Streptococcus agalactiae and, unexpectedly, the anaerobes Gardnerella vaginalis and Prevotella bivia in more than half of the AV samples studied. Yet, despite increased relative abundance of these potential pathogens or pathobionts in the AV bacterial communities, the AV samples only slightly stimulated Toll-like receptor 4 and showed reduced activation of Toll-like receptor 2/6, receptors of two pathways central to mucosal immunity. Our findings indicate that the reduced total bacterial abundance with associated enrichment in certain pathobionts in AV might be mainly a consequence of the inflammatory conditions and/or altered hormonal regulation rather than bacteria being a major cause of the inflammation.

The Correlation Between Abnormal Uterine Artery Flow in the First Trimester and Genetic Thrombophilic Alteration: A Prospective Case-Controlled Pilot Study.

INTRODUCTION: Evaluation of the first trimester uterine artery flow can predict the development of obstetrical complications. A genotype, making women prone to microthrombi. constitutes the main known susceptibility factor for anomalous development of placenta. Our aim was to study whether polymorphisms of 10 genes leading to blood clotting abnormalities are related to abnormal uterine artery blood flow in the first trimester, and may predict placenta-related diseases. MATERIAL AND METHODS: In primary analyses we included 19 singleton pregnancies with abnormal blood flow in the uterine arteries during the first trimester of gestation, and 24 matched control with normal flow patterns. All patients were genotyped for sequence variations in F5, F2, F11, MTHFR, SERPINE-1, CYP4V2, SELE, GP6, angiotensinogen (AGT) and fibrinogen gamma (FGG) genes and followed up until delivery. RESULTS: There were no differences between groups regarding selected sequence variations in any of these genes. The co-occurrence of several polymorphisms in the same patient was also not related to the blood flow patterns in the uterine arteries. CONCLUSIONS: Although we found certain trends of genetic polymorphisms being related to preeclampsia and fetal growth, we failed to find an association between clotting gene polymorphisms, single or in combination, with the abnormal uterine flow in the first trimester.

Impact of a lactobacilli-containing gel on vulvovaginal candidosis and the vaginal microbiome.

Vulvovaginal candidosis (VVC) is a common condition with severe symptoms and high recurrence rates. Probiotic lactobacilli are explored as alternatives to azole treatments. Although the vaginal microbiota is generally not depleted in lactobacilli during VVC, studies indicate that the functionality and antimicrobial activity of the lactobacilli is impaired. We selected three strains from the Lactobacillus genus complex (L. rhamnosus GG, L. pentosus KCA1 and L. plantarum WCFS1) based on in vitro evaluation and formulated them in a gel for vaginal application. This gel was evaluated in 20 patients suffering from acute VVC, who were followed for four weeks including a 10-day treatment period. The microbiome was assessed through 16S rRNA (bacteria) and internal transcribed spacer (ITS; fungi) amplicon sequencing, supplemented with quantitative PCR, culture and microscopy for Candida evaluation. 45% of women did not require rescue medication (3×200 mg fluconazole), implying an improvement of their symptoms. These women showed similar end concentrations of fungi as women treated with fluconazole. Moreover, fluconazole appeared to reduce numbers of endogenous lactobacilli. Our study points towards important aspects for future selection of lactobacilli for probiotic use in VVC and the need to investigate possible negative influences of azoles on the vaginal bacterial community.

ISIDOG Recommendations Concerning COVID-19 and Pregnancy.

Providing guidelines to health care workers during a period of rapidly evolving viral pandemic infections is not an easy task, but it is extremely necessary in order to coordinate appropriate action so that all patients will get the best possible care given the circumstances they are in. With these International Society of Infectious Disease in Obstetrics and Gynecology (ISIDOG) guidelines we aim to provide detailed information on how to diagnose and manage pregnant women living in a pandemic of COVID-19. Pregnant women need to be considered as a high-risk population for COVID-19 infection, and if suspected or proven to be infected with the virus, they require special care in order to improve their survival rate and the well-being of their babies. Both protection of healthcare workers in such specific care situations and maximal protection of mother and child are envisioned.

Two phase 3, double-blind, placebo-controlled studies of the efficacy and safety of Astodrimer 1% Gel for the treatment of bacterial vaginosis.

OBJECTIVE: Astodrimer is a dendrimer formulated in a vaginal gel to treat bacterial vaginosis (BV) and prevent recurrence. The objective of these studies was to confirm the efficacy and safety of Astodrimer 1 % Gel for treatment of BV. STUDY DESIGN: Women with bacterial vaginosis were randomized 1:1 to Astodrimer 1 % Gel (Study 1 conducted in the United States, N = 127; Study 2 conducted in the United States, Germany and Belgium, N = 128) or placebo gel (Study 1, N = 123; Study 2, N = 123) at a dose of 5 g vaginally once daily for 7 days. The primary endpoint was clinical cure, defined as i) absence of bacterial vaginosis vaginal discharge; ii) <20 % clue cells; and iii) negative whiff test at day 9-12. Secondary efficacy analyses included clinical cure at day 21-30. Other endpoints at days 9-12 and 21-30 included Nugent cure (Nugent score ≤3), absence of symptoms, and adverse events. The primary analysis in the modified intent-to-treat population used the Cochran Mantel Haenszel test stratified by analysis center with a two-sided significance level of α = .05. RESULTS: Astodrimer 1 % Gel was superior to placebo for the primary and selected secondary efficacy measures. Clinical cure rates at day 9-12 were 50.4 % (59/117) vs 16.5 % (19/115, P < .001) (Study 1) and 56.7 % (68/120) vs 21.4 % (25/117, P < .001) (Study 2) for astodrimer vs placebo. At day 21-30, clinical cure results showed a similar trend but the difference to placebo was not statistically significant. Nugent cure rates at day 9-12 were 12.8 % (15/117) vs 2.6 % (3/115, P = .004) (Study 1) and 13.3 % (16/120) vs 5.1 % (6/117, P = .030) (Study 2) for astodrimer vs placebo. A greater proportion of women receiving astodrimer reported absence of vaginal discharge and absence of vaginal odor at day 9-12 and day 21-30 compared with placebo. Adverse events were generally mild and self-limiting. For the combined studies, adverse events potentially related to treatment occurred in 14.7 % (37/252) of astodrimer patients vs 9.4 % (23/244) for placebo, including vulvovaginal candidiasis reported for 2.4 % (6/252) of astodrimer patients. CONCLUSION: These results support a role for Astodrimer 1 % Gel as an effective, safe and well-tolerated treatment for women with bacterial vaginosis.

Pharmacotherapy for the treatment of vaginal atrophy.

INTRODUCTION: Despite its frequency, recognition and therapy of vulvovaginal atrophy (VVA) remain suboptimal. Wet mount microscopy, or vaginal pH as a proxy, allows VVA diagnosis in menopause, but also in young contraception users, after breast cancer, or postpartum. Intravaginal low dose estrogen product is the main therapy. Ultra-low-dose vaginal estriol is safe and sufficient in most cases, even in breast cancer patients, while hyaluronic acid can help women who cannot or do not want to use hormones. AREAS COVERED: The authors provide an overview of the current pharmaceutical treatment for vulvovaginal atrophy and provide their expert opinions on its future treatment. EXPERT OPINION: The basis of good treatment is a correct and complete diagnosis, using a microscope to study the maturity index of the vaginal fluid. Minimal dose of estriol intravaginally with or without lactobacilli is elegant, cheap and can safely be used after breast cancer and history of thromboembolic disease. Laser therapy requires validation and safety data, as is can potentially cause vaginal fibrosis and stenosis, and safer and cheaper alternatives are available.

Inhibition of Candida albicans morphogenesis by chitinase from Lactobacillus rhamnosus GG.

Lactobacilli have been evaluated as probiotics against Candida infections in several clinical trials, but with variable results. Predicting and understanding the clinical efficacy of Lactobacillus strains is hampered by an overall lack of insights into their modes of action. In this study, we aimed to unravel molecular mechanisms underlying the inhibitory effects of lactobacilli on hyphal morphogenesis, which is a crucial step in C. albicans virulence. Based on a screening of different Lactobacillus strains, we found that the closely related taxa L. rhamnosus, L. casei and L. paracasei showed stronger activity against Candida hyphae formation compared to other Lactobacillus species tested. By exploring the activity of purified compounds and mutants of the model strain L. rhamnosus GG, the major peptidoglycan hydrolase Msp1, conserved in the three closely related taxa, was identified as a key effector molecule. We could show that this activity of Msp1 was due to its ability to break down chitin, the main polymer in the hyphal cell wall of C. albicans. This identification of a Lactobacillus-specific protein with chitinase activity having anti-hyphal activity will assist in better strain selection and improved application in future clinical trials for Lactobacillus-based Candida-management strategies.

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.

Is multiple-site colonization with Candida spp. related to inadequate response to individualized fluconazole maintenance therapy in women with recurrent Candida vulvovaginitis?

OBJECTIVE: Although most women on fluconazole maintenance therapy for recurrent vulvovaginal candidosis experience a substantial improvement in quality of life, some do not respond to therapy. Is candidal colonization of extragenital sites related to suboptimal response to maintenance therapy? PATIENTS AND METHODS: Women included in a multicenter follow-up study (ReCiDiF) were evaluated for clinical signs and presence of yeasts in nose, mouth, anus, perineum, and urine. Candida was diagnosed by positive microscopy, confirmed by positive culture or polymerase chain reaction. After treatment, women were divided into groups according to their response to a fluconazole maintenance regimen (optimal, suboptimal, and nonresponders). RESULTS: The most frequent extravaginal Candida spp. were detected in urine (79.5%), perineum (78.6%), and anus (56.4%). Carriers of Candida in the mouth were more likely to have it in the anus (OR 3.2; 95% CI 1.4-7.7). Colonization in anus (OR 3.3; 95% CI 1.3-8.1) or in multiple extravaginal sites (OR 3.0; CI95% 1.2-7.4) was related to nonresponse to therapy. Candidal carriage in the anus did not increase anal and perianal symptoms. CONCLUSION: Women with anal carriage and multiple-site candidal colonization are less likely to respond to individualized decreasing dose fluconazole therapy.

Features of syphilis seropositive pregnant women raising alarms in Hungary, 2013-2016.

OBJECTIVES: The incidence of syphilis has been on the rise in Hungary over the last decades. We aimed to assess the syphilis seroprevalence in pregnant women during 2013-2016. The secondary aims were to describe seropositivity by age and gestational age, to estimate infectivity rates in different age groups, and to compare the efficacy of mandatory prenatal screening versus individual venereological testing in revealing syphilis. STUDY DESIGN: During the above mentioned period the reactive serum samples (N = 527) of 49,965 pregnant women undergoing routine screening were submitted for syphilis verification to the Bacterial STI Reference Laboratory, National Center for Epidemiology, Budapest, Hungary. The confirmation process included titrated RPR and TPHA tests performed simultaneously. The tested women were considered seronegative if both tests gave negative results. When any of these tests proved indeterminate or positive, anti-Treponema pallidum IgG and IgM ELISA tests were performed. Patients confirmed for the presence for specific IgG were judged seropositive. Further evaluation of potential infectivity of seropositive patients was carried out on RPR reactivity. RESULTS: Syphilis seropositivity was detected in overall 2.9‰ (N = 148) of the cases. RPR-negative cases, i.e. past infections were confirmed in 36% (53/148); weak-reactive RPR (titres≤8) cases, i. e. past/early acute infections in 37% (55/148); strong-reactive RPR (titres>8) cases suggesting recent syphilis in 27% (40/148). Half of the infectious syphilis cases (20/40) belonged to the 15-24 age group. The gestational age at screening was available of 123 seropositive women, out of whom 27 (22%) were diagnosed late, in the third trimester. Nineteen (13%) out of all seropositives were detected via individual venereological testing before/instead of general prenatal screening. CONCLUSIONS: The majority of infected pregnants may remain undetected due to the lack of mandatory general prenatal screening. The seropositivity for syphilis in pregnancy of 2.9/1000, of which one quarter were recent and infectious, the late diagnosis of syphilis in one in five, and the low pick-up rate of individualised instead of generalized screening are alarming signals and call for more effective prevention strategies, focusing on the most vulnerable adolescents, as well as on the first trimester of pregnancy.

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.
