ABSTRACT

Objective: To determine the etiology of cervico-vaginal infections by cytobacteriology and the efficacy of qPCR for the diagnosis of sensitive strains such as Streptococcus agalactiae, Borrelia crocidurae, Chlamydia trachomatis, Neisseria gonorrhoeae and Treponema pallidum. Methodology: This prospective cross-sectional study was performed between January and September 2021 in 346 women who were examined for cervico-vaginal infection at the Hôpital Principal de Dakar (HPD). Cytobacteriological (direct examination, agar culture) and molecular analyses were performed. Results: Vaginal flora imbalances predominated, with a rate of 72.3%. The proportion of type IV vaginal flora was 46.5%. Of the 199 germs isolated, Candida albicans (25.1%), Ureaplasma urealyticum (17.6%), S. agalactiae (7.8%), Gardnerella vaginalis (6.6%) and nonalbicans Candida (5.5%) were the main pathogens responsible for cervico-vaginal infections in patients. Among women tested for mycoplasma, U. urealyticum was identified in 43.3% of patients. Among those tested for C. trachomatis, the proportion of infected women was low (4%). The prevalence of C. albicans was higher in pregnant women (38.3%) than in nonpregnant women (19.2%). S. agalactiae strains showed high resistance to certain beta-lactam antibiotics (pristinamycin 100%, gentamycin 100%, ampicillin 92.5% and cefalotin 85.2%) and to a glycopeptide antibiotic (vancomycin 100%). The Staphylococcus aureus strain had good sensitivity to antibiotics except gentamycin (100%) and kanamycin (100%). The enterobacteria tested were all sensitive to phenicols, carbapenems, cephalosporins and aminoglycosides. However, E. coli showed high resistance to tetracycline. The different methods showed low prevalences of C. trachomatis and N. gonorrhoeae, so comparisons Test RapidChlamydia/qPCR for C. trachomatis and culture/qPCR for N. gonorrhoeae were not possible. For S. agalactiae, on the other hand, qPCR was more advantageous than culture. The χ2 test showed a significant difference (Yates χ2 = 33.77 and p = 1-7) for the diagnosis of S. agalactiae. S. agalactiae qPCR had a sensitivity of 40.7%, a specificity of 94%, and positive and negative predictive values of 36.7% and 94.9% respectively, as well as a kappa = 0.33. Conclusion: The methods applied enabled us to identify the pathogens that cause cervicovaginal infections. The results suggest that qPCR may be an alternative, at least for the diagnosis of S. agalactiae. However, culture remains indispensable for studying antibiotic sensitivity. In order to improve patient care, molecular techniques need to be integrated into the HPD testing toolbox. To broaden the repertoire of pathogens to be diagnosed by qPCR, targeted comparison studies will be needed to increase the probability of encountering infected individuals.

ABSTRACT

Aerobic vaginitis (AV) is a distinct clinical entity characterized by inflammation and abnormal vaginal microflora. Often mistaken for bacterial vaginosis, AV remains relatively unknown and underdiagnosed. AV's understanding is evolving, with some experts suggesting it may primarily be an immunological disorder, the prevalence of which has a range of 7-13% in non-pregnant women and 4.1-8.3% during pregnancy. Pregnancy can affect susceptibility to vaginal infections, leading to adverse outcomes for the woman and the newborn. This review summarizes the correlation between AV and adverse pregnancy outcomes, particularly preterm birth, the leading cause of morbidity and mortality among neonates. An improved understanding of AV's impact on pregnancy outcomes can lead to early recognition, proper management, and effective interventions. While some studies support an association between AV and preterm labor, the existing knowledge of this relationship remains limited. The evidence suggests that AV may contribute to adverse pregnancy outcomes, mainly preterm birth, but further research is needed to establish a definitive link. Further studies are needed to investigate the underlying mechanisms and clarify AV's role in premature labor. A comprehensive understanding of AV's impact on pregnancy outcomes is crucial for early recognition, appropriate management, and effective interventions.

ABSTRACT

Molecular diagnostic testing (eg, polymerase chain reaction [PCR]-based vaginitis testing) is widely used in clinical practice, although vaginitis experts have reservations about its use for vaginitis diagnosis. As with any new technology, cost to the health system is a large concern. Although clinical evaluation of signs and symptoms along with wet mount microscopy is traditionally used for vaginitis diagnosis, it is less accurate compared with molecular diagnostic testing. Here we review the benefits of adopting newer molecular diagnostics into routine gynecologic practice with some guidance from vaginitis experts that favor both traditional and more modern approaches. We argue that instead of trying to resist the oncoming tide of molecular diagnostics, we can embrace them and put them to appropriate use to effect rapid, accurate, and more flexible diagnosis of vaginitis conditions for our patients.

ABSTRACT

A primigravida in her late 20s presented to the obstetrics and gynaecology department in labour. On per speculum examination, multiple cystic lesions, 1-5 mm in size were observed occupying the anterior, posterior and lateral vaginal walls. Vaginal wet mount was normal and vaginal cultures were negative. Biopsy findings were consistent with emphysematous vaginitis. Vaginitis emphysematosa is a rare, benign self-limiting condition that presents with multiple, air-filled cysts in the vaginal or ectocervical mucosa. This condition is seen in both gravid and non gravid women, usually associated with a Trichomonas or Gardnerella infection.

ABSTRACT

B-cell depleting therapies are effective in multiple sclerosis (MS) and are widely used (Hauser et al., 2017). Inflammatory vaginitis (IV), characterized by unexplained vaginal symptoms including mucopurulent discharge, pain, irritation, and dyspareunia, has been reported in one MS patient on ocrelizumab (Filikci and Jensen, 2022), and to be present in 3.5 % of women on rituximab for autoimmune diseases (Yockey et al., 2021). We report here four cases of IV in B cell depleted women with MS. B-cell reconstitution was temporally associated with improvement of IV symptoms. Further investigation and vigilance for this potential treatment emergent adverse event affecting sexual and reproductive health of women with MS is needed.

ABSTRACT

OBJECTIVE: Aim: To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter retrospective cohort study was conducted from January 2020 to December 2022 in fifteen medical clinics from eight regions of Ukraine. Smears were analyzed using Donders' classification method and Dong's modified AV diagnosis for Gram stains. Definitions of HAIs were adapted from the CDC/NHSN. Antibiotic susceptibility testing of bacteria was determined by Kirby-Bauer disc diffusion test according to the protocol of the EUCAST. RESULTS: Results: Prevalence of AV among women's undergoing gynecologic surgery in Ukraine was 68.7%. Of the total AV cases, 70.3% were in non-pregnant and 29,7% in pregnant women. The most common pathogen of AV was Escherichia coli, followed by Enterococcus faecalis, Streptococcus agalactiae, Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Among the S. aureus strains, 11,6% of MRSA (Methicillin resistant S.aureus) were isolated whereas none of the CoNS were cefoxitin resistant. History of vaginal infection, history of post-operative infection and antibiotic use acted as an important risk factor of AV incidence rate. The presence of AV worsened pregnancy outcomes, by increasing the incidence of preterm birth, the premature rupture of membranes, miscarriage, neonatal jaundice, and neonatal infection. CONCLUSION: Conclusions: Aerobic Vaginitis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, adverse pregnancy outcome, and hence frequent medical visits.

ABSTRACT

El objetivo es conocer el abordaje diagnóstico y terapéutico de la vaginosis citolítica. Para ello se hizo una búsqueda sistemática de la literatura médica mediante las bases de datos: PubMed, Central, etc. Se limitó a ensayos clínicos aleatorizados, metaanálisis y revisiones bibliográficas, con disponibilidad del texto completo para evaluarlos en su totalidad e incluirlos en la revisión; publicados entre 1980 y 2021. Se incluyeron 27 publicaciones. La vaginosis citolítica es un trastorno infradiagnosticado. En mujeres con síntomas y signos de candidiasis vulvovaginal, que no responden a la terapia, se debe considerar la probabilidad de estar en presencia de una vaginosis citolítica. El tratamiento obliga a elevar el pH vaginal a valores básicos y a disminuir el número excesivo de Lactobacillus, resultando de utilidad las duchas vaginales con bicarbonato de sodio y/o un tratamiento con antibióticos derivados de la penicilina junto a un inhibidor de ß-lactamasas o doxiciclina en las pacientes alérgicas a la penicilina. Finalmente, se concluye que la vaginosis citolítica es una afección común, frecuentemente se diagnostica de forma errónea porque se confunde con la candidiasis vulvovaginal; se caracteriza por producir un cuadro clínico similar. El tratamiento se enfoca en disminuir el número de Lactobacillus y la elevación del pH vaginal.


The objective is to know the diagnostic and therapeutic approach of cytolytic vaginosis. A systematic search of the medical literature was carried out using the following databases: Medline via PubMed, Central, and Cochrane Database of Systematic Reviews, among others. The search was limited to randomized clinical trials, meta-analyses, and literature reviews that had the full text available for full evaluation and inclusion in the review; published between 1980 and 2021. Twenty-seven publications were included. Cytolytic vaginosis is a frequently underdiagnosed disorder, which mimics Candida vaginitis. In women with symptoms and signs of vulvovaginal candidiasis who do not respond to antifungal therapy, the possibility of cytolytic vaginosis should be considered. The treatment of this condition requires raising the vaginal pH to basic values and reducing the excessive number of Lactobacillus, resulting in useful vaginal douches with sodium bicarbonate and/or treatment with antibiotics derived from penicillin together with a ß-lactamases inhibitor or doxycycline in patients allergic to penicillin. Finally, we conclude that cytolytic vaginosis is a common condition, frequently misdiagnosed because it is confused with vulvovaginal candidiasis, since it is characterized by producing a similar clinical picture. Treatment focuses on reducing the number of Lactobacillus and raising vaginal pH.

ABSTRACT

Malformações müllerianas correspondem a variações anatômicas do trato repro- dutor feminino. Comumente assintomáticas, o diagnóstico e a verdadeira incidên- cia são difíceis de determinar. A síndrome de Herlyn-Werner-Wunderlich, clas- sicamente descrita pela tríade útero didelfo, hemivagina cega e agenesia renal ipsilateral também pode ter variações diferentes. Em virtude da mesma origem embrionária dos tratos genital e urinário, anomalias renais devem ser investigadas nesses casos, sendo a mais comum a agenesia renal. Este artigo relata o caso de uma paciente de 18 anos, do sexo feminino, com história de piocolpo por cinco anos. Em propedêutica complementar, foi identificado útero com septação com- pleta associado a hemissepto de terço superior de vagina, formação de piocolpo e agenesia renal à direita. Apesar de não ser a definição clássica, o quadro está incluído nos casos de síndrome de Herlyn-Werner-Wunderlich.


Mullerian malformations correspond to anatomical variations of the female repro- ductive tract. Commonly asymptomatic, the diagnosis and true incidence are difficult to determine. The Herlyn-Werner-Wunderlich syndrome, classically described by the triad: uterus didelphus, blind hemivagina and ipsilateral renal agenesis, can also have different variations. Due to the same embryonic origin of the genital and urinary tracts, renal anomalies must be investigated in these cases, the most common being renal agenesis. This article reports the case of an 18-year-old female patient with a 5-year history of pyocolpus. In complementary exams, a uterus with complete septa- tion was identified, associated with a hemiseptum in the upper third of the vagina, formation of pyocolpus and renal agenesis on the right side. Despite not being the classic definition, it is included in the cases of Herlyn-Werner-Wunderlich syndrome.

ABSTRACT

Incomplete merging of the Müllerian ducts may result in vaginal septa or even completely separate vaginal canals. It may also cause cervical malformation. In most cases, there are only rudimentary vaginal septations. Only a few reports describing completely separated vaginal canals (vagina duplex) and a cervix duplex in dogs have been published. This article reports the case of a bitch presented with recurrent vaginitis and cystitis. The symptoms always appeared following the dog's heat. The bitch had been pre-treated by a prior veterinarian as well as in a prior clinic. When presented in the clinic, a vaginal septum was suspected based on digital vaginal examination. Ultrasonographic examination and urinalysis allowed for the diagnosis of bacterial cystitis, which was subsequently treated with antibiotics. The bitch was presented again for vaginal endoscopy, transection of the vaginal septum, and ovariohysterectomy. Both vagina duplex and cervix duplex were diagnosed. Due to the extensive dimensions of the findings, the altered tissue was not resected. No more bacteria were detected in a repeated urine analysis. After spaying, the bitch showed no recurrence of symptoms of cystitis or vaginitis.

ABSTRACT

PURPOSE: Nonspecific vaginitis is a distinct clinical entity with particular microscopic and immunologic features. There is currently no standard of care for women with nonspecific vaginitis. The aim of our study was to assess the change in vaginal symptoms score after 3 months of treatment with an intravaginal medical device in participants with abnormal vaginal discharge and specific signs and symptoms. As secondary objectives, the study analyzed other clinical and microscopic features, such as vaginal discharge aspect, change in vaginal pH, change in vaginal microbiome, and vaginal inflammation. METHODS: The study population included 47 participants with symptomatic vulvovaginitis, distinct from candidiasis, trichomoniasis, or bacterial vaginosis. The study design included 2 research sites from Romania. The treatment protocol consisted of 1 ovule per day inserted intravaginally during 15 consecutive days. The total study duration was 3 months. FINDINGS: The intravaginal medical device had a positive impact on the vaginal symptoms score for 72.34% of the study participants. Topical administration of the ovules balanced vaginal pH values and significantly reduced signs of inflammation between study visits. IMPLICATIONS: This intravaginal medical device had curative effects that support its use as a stand-alone treatment in women with nonspecific vaginitis. A second clinical investigation is ongoing to evaluate the clinical efficacy of the device in postoperative care of cervical and vaginal wounds traumatic or secondary to surgical interventions. CLINICALTRIALS: gov identifier: NCT04735705.

ABSTRACT

Vulvovaginitis occurs in mostly reproductive aged women. Recurrent vaginitis affects overall quality of life, with a large financial burden on the patient, family, and health system. This review discusses a clinician's approach to vulvovaginitis with specific attention to the 2021 updated Center for Disease Control and Prevention guidelines. The authors discuss the role of the microbiome in vaginitis and evidence-based approaches for diagnosis and treatment of vaginitis. This review also provides updates on new considerations, diagnosis, management, and treatment of vaginitis. Desquamative inflammatory vaginitis and genitourinary syndrome of menopause are discussed as differential diagnosis of vaginitis symptoms.

ABSTRACT

Vaginitis emphysematosa (VE) is a rare, benign, and self-limited condition often diagnosed by the presence of intramuscular vaginal air observed on computed tomography (CT) scan. Although it is a nonpathologic, self-limited condition requiring no intervention, it is important to rule out a more serious infectious pathology. This report highlights a clinical dilemma and the potential consequences of over-reliance on CT in distinguishing benign VE from pathologic necrotizing vaginitis. A high clinical suspicion for infection should be maintained, especially when relevant clinical and laboratory markers suggest a more serious pathology. We describe the case of a 45-year-old woman who presented to the hospital with abdominal pain and vaginal bleeding. CT scan demonstrated intramuscular vaginal air, which was reported as VE. Classic imaging findings of VE falsely reassured clinicians. She died shortly thereafter of necrotizing vaginitis.

ABSTRACT

PURPOSE: We aimed to explore the possible function of guiding dominant microflora for aerobic vaginitis (AV) women patients in China to know its diagnostic ability for the further clinical application. METHOD: The characteristics and community compositions of AV vaginal microbiota was evaluated by high-throughput 16S ribosomal RNA (16S rRNA) sequencing after the vaginal microecology evaluations. RESULTS: The increased colonization of Streptococcus agalactiae and Streptococcus anginosus and the absence of Lactobacillus are typical manifestations of AV patients. In addition, Lactobacillus were the major correlated bacteria with control groups of Modified Donders' Score under 3. Most of the significant KEGG pathways were classified into metabolism pathway, where the two bacteria behaved their own metabolism characteristics. CONCLUSION: The increased colonizations of Streptococcus agalactiae and Streptococcus anginosus and the absences of Lactobacillus are the typical manifestations of AV.

ABSTRACT

BACKGROUND: To investigate the positive rate and clinical applicability of liquid-based fungal method for detecting of vaginal fungi. We collect the secretions from the posterior vaginal fornix and the vaginal wall of 198 patients with clinically suspected fungi vaginitis patients for study. METHODS: The vaginal fungi of vaginal discharge were detected by fluorescence method, i.e., by liquid-based thin-layer fungi fluorescence morphology staining detection kit (liquid-based fungal method), saline smear method and fungal culture method. RESULTS: The positive rate of liquid-based fungal method, saline smear method was 50%, 25.75% respectively. The positive rate of liquid-based fungal method were 50%. The true positive rate of liquid-based fungal method (87.85%) was higher than that of saline smear method (45.79%, P < 0.001), which was easy to miss diagnosis. Moreover, the Kappa (K) of liquid-based fungal method was 0.81, and P < 0.01, which was statistically significant, indicating that the consistency of the two detection methods is good. Of the eight common symptoms of fungal vaginitis, the positive symptom coincidence rate of liquid-based fungal method was consistent with that of fungal culture method. It was also easier to see fungi under a microscope than with saline smear method. CONCLUSION: The liquid-based fungal method has a high positive coincidence rate and accuracy in the detection of vaginal fungi, and it is convenient to operate and implement steps. Therefore, it may be applied in clinical practice. Or a combination of several detection methods can be used.

ABSTRACT

Many diverse pathogens have been discovered from reproductive-tract infections, but the relationship between the presence and abundance of particular pathogen species and disease manifestations is poorly defined. The present work examined the association of multiple common pathogens causing sexually transmitted infections (STIs) with cervicitis and vaginitis. The presence and abundance of 15 STI pathogens and the genotypes of human papillomavirus were determined in a cohort of 944 women that included 159 cervicitis patients, 207 vaginitis patients, and 578 healthy controls. Logistic regression and random forest models were constructed and validated in a separate cohort of 420 women comprising 52 cervicitis patients, 109 vaginitis patients, and 259 healthy controls. The frequency of individual STI pathogen species varied among the symptomatic patients and healthy controls. Abundance determination was necessary for most pathogens that were associated with the studied diseases. STI pathogens were more commonly associated with cervicitis than with vaginitis. Pathogen identification- and quantification-based diagnosis was observed for cervicitis with high sensitivity and specificity, but for vaginitis, the assay results would need to be combined with results of other diagnostic tests to firmly establish the pathogen-disease correlation. Integrated qualitative and quantitative detection of a selected panel of common STI pathogens can reveal their association with cervicitis and vaginitis. STI pathogen identification and quantification can be used to diagnose cervicitis and also help improve correct diagnosis of vaginitis. IMPORTANCE Scarce information exists with regard to whether STI pathogens can be defined as valid microbiological predictive markers for the diagnosis of cervicitis and vaginitis. We therefore conducted this study to assess the presence and abundance of a wide range of STI pathogens among patients having these two diseases and healthy controls as well. High sensitivity and specificity were observed for cervicitis by pathogen identification- and quantification-based diagnosis. In contrast, the assay results obtained for vaginitis would need to be combined with test results obtained by other diagnostic methods to decisively establish the pathogen-disease correlation. Simultaneous qualitative and quantitative detection of a selected panel of common STI pathogens and further coupling with machine learning models is worthwhile for establishing pathogen-based diagnosis of gynecological inflammations, which could be of great value in guiding the rational use of antimicrobials to control the spread of STIs.

ABSTRACT

OBJECTIVE: To compare the diagnosis of bacterial vaginosis (BV) by Nugent scoring criteria (Nugent-BV) and the diagnosis of BV and/or aerobic vaginitis (AV) using Donders criteria (Donders-BV/AV) for identifying Molecular-BV detected by bacterial 16s rRNA profiling. METHODS: We enrolled 512 women of reproductive age in Brazil with data available on Nugent and Donders microscopic analysis and 16S rRNA sequencing. We constructed receiver operating characteristic (ROC) curves of Nugent-BV and Donders-BV/AV and calculated their area under the curves (AUCs) and 95% confidence interval (CI) for matching Molecular-BV. RESULTS: A total of 155 (28.7%) participants were positive for Nugent-BV. Donders-BV and -AV were detected in 90 (17.6%) and 75 (14.6%) participants, respectively, while 28 (5.5%) had concurrent Donders-BV and -AV. Molecular-BV was identified in 139 (27.1%) participants. Analysis of ROC curves showed that diagnosis of Nugent-BV more accurately aligned with presence of Molecular-BV (AUC: 0.88, 95% CI: 0.84-0.91) when compared to Donders-AV/BV (AUC: 0.84; CI: 0.80-0.87) (P = 0.005). CONCLUSION: The use of Nugent-BV is more representative of Molecular-BV than Donders-AV/BV.

ABSTRACT

Vaginitis is a common condition that affects women of reproductive age. Early and accurate diagnosis and identification of the causative agents (ie, fungi, protozoa, bacterial species, etc.) help to avoid incorrect treatment and subsequent visits that add costs and therapies, which increase overall health care utilization. A prior study by Kong et al presented a cost analysis demonstrating that women who received a nucleic acid amplification test (NAAT) on the day of their vaginitis diagnosis had significantly lower 12-month follow-up costs than women who received a direct probe (DP) test or women who received clinical evaluation without the use of a molecular test. This prior analysis included pregnant women, which may have influenced the findings. The objective of this analysis is to determine whether the exclusion of pregnant women from the study cohort impacts the previously observed NAAT cost-savings results. The current analysis adds evidence that nonpregnant women diagnosed with NAAT at their initial visit have significantly lower 12-month overall health care costs than women evaluated through DP or other clinical methods. This is an update to an article titled "Diagnostic Testing of Vaginitis: Improving the Value of Care," which was published on August 16, 2021 and is available at https://doi.org/10.1089/pop.2021.0143.

ABSTRACT

Background: The diagnosis and treatment of mixed vaginitis are more complicated than single pathogenic infections, and there may be adverse reactions and several contraindications to conventional antibiotic therapy. Therefore, this study aimed to evaluate the preliminary effects of Fufang Furong Effervescent Suppository for the management of aerobic vaginitis (AV) mixed with bacterial vaginosis (BV) using Accurate 16S absolute quantification sequencing (Accu16S). Methods: In the present randomized, blind, multi-center clinical trial, women (20 to 55 years) who had received a diagnosis of AV+BV were randomly assigned into clindamycin positive control (n = 41) and Fufang Furong Effervescent Suppository (n = 39) groups. The follow-up occurred in three time periods (V1: -2~0 days; V2: 15-17 days; V3: 40 ± 3 days). At each visit, two vaginal swabs, one for clinical evaluation and one for laboratory examination, were taken from each patient. The Nugent score, Donders' score, drug-related complications, recurrence rates, and microecological changes of vaginal swabs were assessed in the time three periods. Results: At baseline, the two groups were similar in frequency of presentation with vaginal burning, odor, abnormal discharge, and itching. No meaningful differences in Nugent and Donders' scores were detected between the two groups at stage V2 (Nugent: p = 0.67; Donders': p = 0.85) and V3 (Nugent: p = 0.97; Donders: p = 0.55). The Furong group presented fewer complications compared to the Clindamycin group. However, this difference was not statistically significant (p = 0.15). Additionally, Accu16S indicated that the total abundance of bacteria in both groups sharply decreased in stage V2, but slightly increased in V3. In stage V3, the absolute abundance of Lactobacillus in the Furong group was considerably higher compared to untreated samples (p < 0.05). On the other hand, no momentous increase was detected in the Clindamycin group (p > 0.05). Conclusion: Fufang Furong Effervescent Suppository can be as effective as clindamycin cream in the management of AV+BV while may restore the vagina microecosystem better.
