Could tranexamic acid be a suitable alternative to cryotherapy for symptomatic cervical ectopy? Results from a randomized clinical trial.

OBJECTIVE: Cervical ectropion occurs due to the eversion of the endocervix that exposes glandular cells to the vaginal milieu. The aim of the present study was to evaluate and compare the clinical efficacy of effervescent vaginal tablets of tranexamic acid and cryotherapy in women with symptomatic cervical ectopy. METHODS: The current randomized clinical trial was conducted on 92 samples of women with cervical erosive ectropion from March 20, 2022 to August 27, 2022. Participants were divided into two groups; the intervention group (n = 46) was treated with a 400 mg effervescent vaginal tablet of tranexamic acid and the control group (n = 46) underwent cryotherapy. All the patients were requested to visit weekly in the first month and then monthly for the next 3 months, and the outcomes encompass improvement of symptoms (leukorrhea, dyspareunia, pelvic pain, post-coital bleeding, and suprapubic pain) and cervical erosive ectropion view were monitored based on repeated examinations. RESULTS: In this study, no statistically significant difference was observed in cure rate of symptoms between study groups (P value > 0.05). Women in both the tranexamic acid and cryotherapy groups reported significant improvements in dyspareunia (34 [75%] vs 31 [67%]), pelvic pain (34 [75%] vs 34 [74%]), post-coital bleeding (37 [81%] vs 31 [67%]), leukorrhea (36 [78%] vs 36 [78%]), suprapubic pain (32 [71%] vs 33 [73%]) disappearance of cervical ectropion tranexamic acid (40 [86%], vs 39 [84%]). CONCLUSION: Our findings highlighted the equal effect of tranexamic acid and cryotherapy for treating cervical ectropion. Due to the ease of use, availability, and fewer side effects of tranexamic acid, it can be a suitable alternative to cryotherapy. TRIAL REGISTRATION: IRCT20220115053719N1.

Altered Vaginal Microbiota Composition Correlates With Human Papillomavirus and Mucosal Immune Responses in Women With Symptomatic Cervical Ectopy.

Cervical ectopy is a benign condition of the lower genital tract that is frequently detected in women of reproductive age. Although cervical ectopy is regarded as a physiological condition, some women experience symptoms such as leucorrhoea, persistent bleeding and recurrent vaginal infections that require medical intervention. Cervical ectopy has not been linked to cervical cancer, but it is thought to facilitate the acquisition of sexually transmitted diseases (STDs), like Human Papillomavirus (HPV) infection, as it provides a favorable microenvironment for virus infection and dissemination. We and others have described the presence of oncogenic HPV types in women with symptomatic cervical ectopy. The relevance of this finding and the impact of symptomatic cervical ectopy on the cervicovaginal microenvironment (vaginal microbiota, immune and inflammatory responses) are currently unknown. To shed some light into the interplay between HPV, the vaginal microbiota and mucosal immune and inflammatory responses in the context of this condition, we enrolled 156 women with symptomatic cervical ectopy and determined the presence of HPV using a type-specific multiplex genotyping assay. Overall, HPV was detected in 54.48% women, oncogenic HPV types were found in more than 90% of HPV-positive cases. The most prevalent HPV types were HPV16 (29.4%), HPV31 (21.17%) and HPV18 (15.29%). Next, we evaluated the vaginal microbial composition and diversity by 16S rDNA sequencing, and quantified levels of cytokines and chemokines by flow cytometry using bead-based multiplex assays in a sub-cohort of 63 women. IL-21 and CXCL9 were significantly upregulated in HPV-positive women (p=0.0002 and p=0.013, respectively). Women with symptomatic cervical ectopy and HPV infection had increased diversity (p<0.001), and their vaginal microbiota was enriched in bacterial vaginosis-associated anaerobes (Sneathia, Shuttleworthia, Prevotella, and Atopobium) and depleted in Lactobacillus spp. Furthermore, the vaginal microbiota of women with symptomatic cervical ectopy and HPV infection correlated with vaginal inflammation (IL-1ß, rho=0.56, p=0.0004) and increased mucosal homeostatic response (IL-22, rho=0.60, p=0.0001). Taken together, our results suggest that HPV infection and dysbiotic vaginal communities could favor a vaginal microenvironment that might delay the recovery of the cervical epithelium in women with symptomatic cervical ectopy and favor STDs acquisition.

Cervical Ectropion May Be a Cause of Desquamative Inflammatory Vaginitis.

Desquamative inflammatory vaginitis is a poorly understood chronic vaginitis with an unknown etiology. Symptoms of desquamative inflammatory vaginitis include copious yellowish discharge, vulvovaginal discomfort, and dyspareunia. Cervical ectropion, the presence of glandular columnar cells on the ectocervix, has not been reported as a cause of desquamative inflammatory vaginitis. Although cervical ectropion can be a normal clinical finding, it has been reported to cause leukorrhea, metrorrhagia, dyspareunia, and vulvovaginal irritation. Patients with cervical ectropion and desquamative inflammatory vaginitis are frequently misdiagnosed with candidiasis or bacterial vaginosis and repeatedly treated without resolution of symptoms. We report the case of a 34-year-old woman with a 4-year history of profuse yellowish discharge and dyspareunia. Upon presentation, her symptoms and laboratory results met the criteria for desquamative inflammatory vaginitis, but the standard treatments did not provide long-lasting relief. As a last resort, cryotherapy (cryosurgery) of her cervix was performed for treatment of her cervical ectropion, which provided complete resolution of her symptoms.

Therapeutic effects of traditional Chinese medicine in patients with symptomatic cervical ectopy.

PURPOSE: The aim of this study is to evaluate the treatment and efficacy of Badushengjigao, a traditional Chinese medicine (TCM) formula, for symptomatic cervical ectopy. METHOD: A patient self-selected two group comparison study was performed. One hundred patients with symptomatic cervical ectopy admitted to the Central Hospital of E-Zhou (Hubei, China) between July 2013 and July 2014 were enrolled in the study. The patients treated with Badushengjigao were the study group and the patients treated with policresulen suppository were the control group. The medicine was administered through vagina. Patients received a three-month follow-up (once a month). The treatment results were evaluated and analyzed by variance analysis and X(2) test. RESULTS: The curative rates of the two groups with symptomatic cervical ectopy grade 1 shows no statistical significance. As for grade 2 and grade 3, the curative rates of the study group (phase 2: 72.0%; phase 3: 62.5%) are higher than that of the control group (phase 2: 44.4%; grade 3: 54.5%) with statistical difference (P < 0.05). The study group has less adverse effects (2.5 ± 1.3 days of vagina bleeding, 6 cases of abdominal pain and 2 cases of increased discharge) than the control group (12.5 ± 1.1 days of vagina bleeding, 15 cases of abdominal pain and 42 cases of increased discharge) with distinctive statistical difference (P < 0.01). CONCLUSION: The TCM formula, Badushengjigao, seems to be more effective than policresulen suppositories in treating symptomatic cervical ectopy phase 2 and phase 3. We suggest that it could be used as an alternative method for symptomatic cervical ectopy treatment, but further study is needed.

Efficacy and safety of focused ultrasound versus microwave therapy for cervical ectopy: a meta-analysis.

OBJECTIVES: To assess the efficacy and safety of focused ultrasound therapy (FU) and microwave therapy (MW) for cervical ectopy (CE). METHODS: We searched PubMed, EMbase, the Cochrane Library, Chinese Biomedical Literature Database (CBM), Chinese Scientific Journals Database (VIP), China Academic Journals Full-text Database (CNKI), and WanFang Data for randomized controlled trials (RCTs) comparing FU with MW for women with symptomatic CE from inception to 30 August 2014. Two review authors (Tang XL and Gao Z) independently screened for eligible studies according to the inclusion and exclusion criteria, extracted data and assessed risk of bias of included RCTs. Then, meta-analysis was performed using the RevMan 5.2 software. Funnel plots were used to evaluate publication bias. RESULTS: A total of 33 RCTs with 11,759 participants were included. All studies had high risk of bias. The results of meta-analysis indicated that compared to MW, FU significantly reduced the risk of vaginal bleeding (RR = 0.09, 95%CI 0.05 to 0.17, P < 0.00001) and vaginal discharge (RR = 0.10, 95%CI 0.04 to 0.24, P < 0.00001), increased the cure rate (RR = 1.10, 95%CI 1.05 to 1.15, P < 0.0001) and the total effectiveness rate (RR = 1.04, 95%CI 1.02 to 1.06, P = 0.0005), and decreased the recurrence rate (RR = 0.13, 95%CI 0.02 to 1.00, P = 0.05); however, this last difference was not statistically significant. CONCLUSION: Current available evidence suggests that FU is safer and more effective than MW for treating CE. However, some limitations will reduce the reliability of our results. Further well-designed clinical trials are needed to provide further clarification.

Uterine cervical ectopy during reproductive age: cytological and microbiological findings.

Cervical ectopy is common in adolescents, pregnant women, and those taking high doses of estrogen-containing contraceptives. The majority of cases have spontaneous reversion, but some cases can be persistent. Studies suggested that the adequacy of a Pap smear could be affected and there is an increased risk cervical infections. This study is a cross-sectional study conducted from December 2009 to February 2011 with 457 women with cervical ectopy and 736 without ectopy. Cervical samples were collected in vials for analysis by ThinPrep cytology (Hologic, Marlborough, MA). The Mann-Whitney test and Fisher's exact test (95% CI) were applied. The study was approved by the ethics committee of the Federal University of Ceará. The mean ages of the study group and control group were 28.7 (±14.8) and 33.6 (±7.5) years old, respectively (P < 0.0001). Negative diagnosis for malignancy and intraepithelial lesion was present in 399 (87%) cases and 705 (96%) in the study and control groups, respectively (P < 0.0001). Shift in the flora suggestive of bacterial vaginosis (BV) was observed more frequently in the study group: 74 (16.2%) than in the control group: 86(11.7%) (P = 0.017). The differences among the other morphotypes showed no significance. The smears were atypical in 12.7% (58/457) of the patients from the study group and in 4.2% (31/736) in the control group (P < 0.001; RR = 3 [2.033-4.712]). The association between ectopy and inflammatory cytology, the presence of the shift in the flora suggestive of BV and cytological atypia is evident.

Caracterización del tejido columnar del cérvix mediante espectroscopia de impedancia eléctrica y modelado computacional / Characterization of cervical columnar tissue through electrical impedance spectroscopy and computer modeling

RESUMEN Introducción: En este artículo se presenta la utilización de la espectroscopia de impedancia eléctrica (EIE) en la caracterización del tejido columnar cervical y como herramienta de apoyo a las técnicas diagnósticas del cáncer de cuello uterino. Métodos: Se realizó un estudio de validez diagnóstica a 30 pacientes no menopáusicas que presentaron ectopia cervical durante la colposcopia. Se obtuvieron 129 espectros de impedancia eléctrica de tejido columnar, que fueron diferenciados en cuatro zonas o puntos de toma de medidas, semejantes a las zonas horarias 12, 3, 6, y 9 de un reloj análogo. Los datos experimentales obtenidos fueron ajustados al modelo de Cole-Cole, que describe la fisiología y estructura del tejido mediante parámetros eléctricos de resistividad R y S, frecuencia característica Fc y capacitancia de membrana Cm. Resultados: La comparación entre tejidos columnares sanos y con lesión en cada uno de los puntos de medida se realizó mediante pruebas no paramétricas U de Mann-Whitney, que mostraron diferencias estadísticamente significativas (p <0,05) para las medianas de R y S, con un nivel de confianza del 95%. Los valores promedio de R y S para tejido columnar sano fueron 2,0 Ω-m y 11,36 Ω-m, con desviación estándar 0,41 y 0,51 respectivamente; mientras que para los tejidos con lesiones el valor promedio R y S fueron de 4,21 Ω-m y 7,03 Ω-m, con desviación estándar 0,40 para ambas medidas. Conclusión: Se encontró que la resistividad del líquido extracelular R y la resistividad de la matriz intracelular S son las que mejor discriminan entre epitelios columnares sanos y aquellos afectados por lesiones.

ABSTRACT Introduction: Thi s pape r shows the implementation of Electrical Impedance Spectroscopy (EIS) in the characterization of the cervical columnar tissue and as a supporting tool to the diagnostic techniques of cervical cáncer Methods: A diagnostic validity study was performed on 30 non-menopausal patients who presented cervical ectopy during colposcopy. A total of 129 electric impedance spectra of columnar tissue was obtained, which were differentiated into four measurement zones or points similar to time zones 12, 3, 6, and 9 of an analog clock. The experimental data obtained were adjusted to the Cole-Cole model which describes the physiology and structure of the tissue through electrical resistivity parameters R and S, characteristic frequency Fc and membrane capacitance Mc. Results: The comparison between healthy and damaged columnar tissue at each of the measurement points was performed using non-parametric Mann-Whitney U tests which showed statistically significant differences (p <0.05) for the R and S medians with a 95% confidence level. The average values of R and S for healthy columnar tissue were 2.0 Ω-m and 11.36 Ω-m, with 0.41 and 0.51 standard deviation respectively, whereas for a damaged tissue the average value of R and S were 4.21 Ω-m and 7.03 Ω-m, with 0.40 standard deviation for both measurements. Conclusions: It was found that the resistivity of the extracellular liquid R, and the resistivity of the intracellular matrix S, are the parameters that better discriminate between healthy columnar epithelia and those affected by lesions.
