Vaginosis citolítica: actualización diagnóstica y terapéutica / Cytolytic vaginosis: diagnostic and therapeutic update

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.

Bacterial vaginosis and trichomoniasis: prevalence, associated factors, and performance of diagnostic tests

Introduction: Bacterial vaginosis and vaginal trichomoniasis are frequent causes of health care demand. Objective: To estimate the prevalence, identify associated factors, and investigate the performance of diagnostic tests for bacterial vaginosis and trichomoniasis. Methods: Cross-sectional study with participants over 18 years old. All of them were submitted to an interview and gynecological examination with evaluation of vaginal secretion, pH verification, collection of material for Pap smear, wet mount test, Whiff test, bacterioscopy, and polymerase chain reaction for trichomoniasis detection. Logistic regression analysis was applied to identify associated factors with bacterial vaginosis. Diagnostic performance for bacterial vaginosis was evaluated following Amsel criteria, the Ison and Hay score, and the Pap smear, considering the Nugent score as the gold standard. As for trichomoniasis, diagnostic performance was evaluated through the Pap smear and the wet mount test, using the polymerase chain reaction as the gold standard. Results: The prevalence of bacterial vaginosis was 33.7%, and for trichomoniasis, 0.5%. The complaint of abnormal vaginal secretion was associated with the diagnosis of bacterial vaginosis (odds ratio 2.2). The diagnostic accuracy by Amsel criteria, the Ison and Hay score, and the Pap smear was 35.6, 97.0, and 84.2%, respectively. The sensitivity for trichomoniasis through wet mount test was 0.0%, and through the Pap smear, 100%. Conclusion: The prevalence of bacterial vaginosis was high, and trichomoniasis was low. The only associated factor with bacterial vaginosis was the report of abnormal vaginal secretion. The methods with the most accurate diagnostic performance for bacterial vaginosis were the Ison and Hay score and the Pap smear and, for trichomoniasis, the Pap smear

Prevalence and factors associated with bacterial vaginosis in women in Brazil: a systematic review / Prevalência e fatores associados à vaginose bacteriana em mulheres no Brasil: uma revisão sistemática

Introduction: Bacterial vaginosis is characterized by the imbalance of the vaginal flora, with decrease in Lactobacillus and increase in other bacteria. Objective: To investigate the prevalence and factors associated with bacterial vaginosis. Methods: Systematic review based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, filed in the International Prospective Register of Systematic Reviews. The research was conducted in the PubMed and Scopus databases in September 2021. After reading the titles and abstracts of 84 articles and the full text of 20 articles, 10 of them were included in the review. The articles were considered eligible if they investigated the prevalence of bacterial vaginosis and used Amsel's diagnostic criteria or Gram-stained bacterioscopy in women of reproductive age without comorbidities. The studies were evaluated by two investigators to establish reliability. The risk of bias and the quality of the selected studies were evaluated using the Joanna Briggs Institute tool. Results: The mean prevalence of bacterial vaginosis in the included studies was 25.4% (95%CI 24.0­26.8). In three population-based studies, the mean prevalence was 18.1% (95%CI 16.0­20.5); and in seven clinic-based studies, it was 27.2% (95%CI 24.6­29.9). The factors associated with bacterial vaginosis were the use of sex accessories (OR 2.4; 95%CI 1.1­4.9), marital status "single" (OR 1.4; 95%CI 1.1­1.8), partner infidelity (OR 1.5; 95%CI 1.2­1.9), abnormal vaginal secretion (OR 1.5; 95%CI 1.2­2.0), and the presence of trichomoniasis (OR 4.1; 95%CI 1.5­11.5). Conclusion: The prevalence of bacterial vaginosis was high, and the associated factors are linked to sexual behavior.

Introdução: A vaginose bacteriana caracteriza-se pelo desequilíbrio da flora vaginal, com diminuição dos Lactobacillus e aumento de outras bactérias. Objetivo: Investigar a prevalência e os fatores associados à vaginose bacteriana. Métodos: Revisão sistemática baseada nas diretrizes do Preferred Reporting Items for Systematic Reviews and Meta-Analyses, protocolado no International Prospective Register of Systematic Reviews. A pesquisa foi realizada nas bases de dados da PubMed e da Scopus, em setembro de 2021. Após a leitura dos títulos e dos resumos de 84 artigos e do texto completo de 20 artigos, dez foram incluídos na revisão. Os trabalhos foram considerados elegíveis quando investigaram a prevalência de vaginose bacteriana e utilizaram os critérios diagnósticos de Amsel ou a bacterioscopia corada pelo Gram em mulheres em idade reprodutiva e sem comorbidades. Os estudos foram avaliados por duas pesquisadoras para estabelecer a confiabilidade. O risco de viés e a qualidade das pesquisas selecionadas foram avaliados pela ferramenta do Joanna Briggs Institute. Resultados: A prevalência média de vaginose bacteriana nos trabalhos incluídos foi de 25,4% (intervalo de confiança ­ IC95% 24,0­26,8). Em três estudos de base populacional, a prevalência média foi de 18,1% (IC95% 16,0­20,5); e, em sete estudos de base clínica, a prevalência média foi de 27,2% (IC95% 24,6­29,9). Os fatores associados à vaginose bacteriana foram o uso de acessórios sexuais (odds ratio ­OR 2,4; IC95% 1,1­4,9), estado civil "solteira" (OR 1,4; IC95% 1,1­1,8), infidelidade do parceiro (OR 1,5; IC95% 1,2­1,9), secreção vaginal anormal (OR 1,5; IC95% 1,2­2,0) e presença de tricomoníase (OR 4,1; IC95% 1,5­11,5). Conclusão: A prevalência de vaginose bacteriana foi elevada e os fatores associados estão ligados ao comportamento sexual.

Objective. To describe the in vitro antimicrobial activity of the methanolic extract of Bixa orellana L. leaves against anaerobic bacteria associated to bacterial vaginosis and Lactobacillus spp. Materials and methods. Eight ATCC reference strains; Gardnerella vaginalis, Prevotella bivia, Peptococcus niger, Peptostreptococcus anaerobius, Mobiluncus curtisii, Atopobium vaginae, Veillonella parvula, and Lactobacillus crispatus, and twenty-two clinical isolates; eleven Gardnerella vaginalis and eleven Lactobacillus strains, were included in the study. The antimicrobial susceptibility was determined by the agar diffusion method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by using agar dilution and a modified dilution plating method, respectively. Results. All ATCC reference strains showed high levels of susceptibility to the extract, except P. vibia, V. parvula and L. crispatus. Interestingly, all G. vaginalis clinical isolates and the G. vaginalis ATTC strain were the most susceptible to the extract, given their low MIC (1.0 - 2.0 mg/mL) and MBC (1.0 - 4.0 mg/mL) values, whereas, the Lactobacillus spp. clinical isolates and the L. crispatus ATCC strain were the least susceptible bacteria given their high MIC (32.0 mg/mL) and MBC (≥ 32.0 mg/mL) values. Conclusions. In vitro experiments suggest that the extract possesses selective antimicrobial properties given its high activity against bacterial vaginosis-associated anaerobic bacteria and low activity against Lactobacillus species.

Guia practica clinica para el manejo de parto pretermino / Clinical practice guide for the management of preterm birth

El parto pretérmino en la región centroamericana tiene variaciones en cada país, así como la mortalidad perinatal neonatal y materna que se deriva de la condición. La atención adecuada sigue siendo una barrera en las zonas con más limitaciones en los servicios y el personal sanitario disponible. El parto pretérmino es considerado un problema con implicaciones sociales y económicas que produce impacto a corto, mediano y largo plazo (Goldenberg, 2012). El 75% de las complicaciones que genera conllevan a un aumento en la mortalidad infantil. La mayoría de sus factores de riesgo son considerados como prevenibles con la implementación de medidas sencillas y económicas (WHO, 2015). La investigación clínica de esta condición, en una gran mayoría, se ha generado en países de alto ingreso (Opiyo, 2017) 1 . Algunas veces se desconocen los resultados de algunas intervenciones en condiciones de recursos limitados. Esta guía presenta y pretende abordar algunas de estas limitaciones. También alerta sobre algunas intervenciones que pueden producir más problemas y dificultades si se implementan, al considerar los recursos disponibles en los lugares donde se desarrollaron las investigaciones que generaron la evidencia y hacer la comparación con la realidad de los países de Centroamérica en donde se usará la evidencia. Por otra parte, para cada recomendación que en este instrumento se facilita, los resúmenes de evidencia consideran las efectividades clínicas y los efectos adversos cuando han estado disponibles.

Bacterial vaginosis, cervical Human Papillomavirus infection and cervical cytological abnormalities in adult women in Central Brazil: a cross-sectional study / Vaginose bacteriana, infecção cervical pelo Papilomavírus humano e anormalidades citológicas cervicais em mulheres adultas no Brasil Central: um estudo transversal

Bacterial vaginosis is the most common cause of vaginal discharge and occurs when there is an imbalance in the vaginal microbiota, predominantly composed of Lactobacillus spp. Human Papillomavirus is the most common sexually transmitted virus in the world. Persistent infection with high-risk Human Papillomavirus genotypes is the main cause of the development of cervical intraepithelial neoplasia and cervical cancer. Objective: To investigate the association between bacterial vaginosis and cervical Human Papillomavirus infection and between bacterial vaginosis and cervical cytological abnormalities in adult women. Methods: Cross-sectional study carried out in a gynecology outpatient clinic of the public health network. A total of 202 women were included in the study and underwent gynecological examination with cervical specimen collection. Cervical cytopathological examinations and bacterioscopy by the Nugent method were performed to identify bacterial vaginosis, and PCR and reverse hybridization were carried out for Human Papillomavirus detection and genotyping. Bivariate analysis was performed to investigate the association between bacterial vaginosis and cervical Human Papillomavirus infection, and between bacterial vaginosis and cervical cytological abnormalities. The odds ratio was calculated, with the respective 95% confidence intervals (95%CI) and 5% significance level (p≤0.05). Results: The prevalence of bacterial vaginosis was 33.2% (67/202), the prevalence of cervical Human Papillomavirus infection was 38.6% (78/202) and the prevalence of cervical cytological abnormalities was 6.0% (12/202). Bivariate analysis showed no significant association between bacterial vaginosis and cervical Human Papillomavirus infection (OR 0.69; 95% CI 0.37­ 1.27; p=0.23), or between bacterial vaginosis and cervical cytological abnormalities (OR 0.65; 95%CI 0.17­2.50; p=0.54). Conclusion: In this study, bacterial vaginosis did not represent a risk factor for cervical Human Papillomavirus infection or for the presence of cervical cytological abnormalities in the investigated adult women.

A vaginose bacteriana é a causa mais comum de corrimento vaginal e ocorre quando há um desequilíbrio da microbiota vaginal, composta predominantemente de Lactobacillus spp. O papilomavírus humano é o vírus sexualmente transmissível mais comum no mundo. A infecção persistente com genótipos do papilomavírus humano de alto risco é a principal causa do desenvolvimento de neoplasias intraepiteliais cervicais e câncer de colo do útero. Objetivo: Investigar a associação entre vaginose bacteriana e infecção cervical pelo papilomavírus humano e entre vaginose bacteriana e anormalidades citológicas cervicais em mulheres adultas. Métodos: Estudo de corte transversal realizado em um ambulatório de ginecologia da rede pública de saúde. O total de 202 mulheres foi incluído no estudo e submetido ao exame ginecológico com coleta de espécime cervical. Foram realizados os exames citopatológicos cervicais, a bacterioscopia pelo método de Nugent para a identificação da vaginose bacteriana e reação em cadeia da polimerase e hibridização reversa para a detecção e genotipagem do papilomavírus humano. Análise bivariada foi realizada para investigar a associação entre vaginose bacteriana e infecção cervical pelo papilomavírus humano e entre vaginose bacteriana e anormalidades citológicas cervicais. Foi calculado o odds ratio, com os respectivos intervalos de confiança de 95% (IC95%) e nível de significância de 5% (p≤0,05). Resultados: A prevalência da vaginose bacteriana foi de 33,2% (67/202), a da infecção cervical pelo papilomavírus humano foi de 38,6% (78/202) e a de anormalidades citológicas cervicais foi de 6,0% (12/202). A análise bivariada não demonstrou associação significativa entre vaginose bacteriana e infecção cervical pelo papilomavírus humano (OR 0,69; IC95% 0,37­1,27; p=0,23), nem entre vaginose bacteriana e anormalidades citológicas cervicais (OR 0,65; IC95% 0,17­2,50; p=0,54). Conclusão: Neste estudo a vaginose bacteriana não representou um fator de risco para a infecção cervical pelo papilomavírus humano e nem para presença de anormalidades citológicas cervicais nas mulheres adultas investigadas

Bacterial vaginosis and cervical human papillomavirus infection in young and adult women: a systematic review and meta-analysis

ABSTRACT OBJECTIVE To investigate the association between bacterial vaginosis and cervical human papillomavirus (HPV) infection in young and adult women. METHODS This systematic review and meta-analysis was based on the Prisma methodological guidelines. PubMed and Web of Science were searched using the following descriptors: "bacterial vaginosis and HPV", in June 2019. Articles published from 2012 to 2019 were included. Inclusion criteria were original studies that investigated the association between bacterial vaginosis and cervical HPV infection; articles published in English, Spanish or Portuguese; studies conducted in young and adult, non-pregnant, non-HIV-infected women; studies that used the Nugent criteria for the diagnosis of bacterial vaginosis and studies in which the detection of HPV used the polymerase chain reaction technique. Assembled data, odds ratio (OR) and respective 95% confidence intervals (95%CI) were estimated for the association between bacterial vaginosis and cervical HPV infection using random-effects models. A bilateral value of p < 0.05 was considered statistically significant. RESULT Six studies were selected for analysis and demonstrated association between bacterial vaginosis and cervical HPV infection (OR = 2.68; 95%CI: 1.64-4.40; p < 0.001). CONCLUSION Bacterial vaginosis was considered a risk factor for cervical HPV infection, since women with bacterial vaginosis were more likely to be infected with HPV.

Prevalence of bacterial vaginosis in pregnant women attending Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria using the complete Amsel's diagnostic criteria

Background: Bacterial vaginosis (BV) in pregnant women remains a cause for clinical concern among clinicians and health care professionals. BV has been linked to prenatal, antenatal and postnatal challenges in pregnant women. Information on prevalence of BV across trimesters of pregnancy is expected to give better clinical insight into the pathophysiology of this polymicrobial disorder. This study was conducted to determine the prevalence of BV in pregnant women attending the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Methodology: This was a cross-sectional study of 120 pregnant women (40 in each trimester of pregnancy) who had symptoms suggestive of BV, selected by systematic random sampling from among the women attending the Obstetrics and Gynaecology (O & G) clinic of NAUTH, Nnewi. Each subject participant was examined by the attending clinician, and high vaginal swab (HVS) sample was collected for diagnostic analysis of BV using with complete Amsel's clinical criteria, which consists of three of the four criteria; (i) adherent and homogenous vaginal discharge, (ii) vaginal pH > 4.5, (iii) detection of clue cells on saline wet mount, and (iv) amine odor after the addition of potassium hydroxide (positive Whiff test). Results: The mean age of the 120 selected participants was 27.25±6.09 years. The age groups 25-29 (36.7%) and 20-24 years (33.3%) constituted the largest proportion, while age groups <20 (5.0%) and 40-45 years (5.0%) constituted the least. Of the 120 participants, 26 (21.7%) were positive for BV by the Amsel's criteria. Pregnant women in age group <20 years had the highest prevalence of BV (100%, 6/6), followed by those in the age groups 20-24 (27.5%), 40-45 (16.7%), 25-29 (15.9%), 30-34 (9.1%) and 35-39 years (0%) (X 2=28.063, p=0.0001). Prevalence of BV was significantly higher in single (unmarried) pregnant women (45.5%, X 2=4.038, p=0.045), women with primary school education level (66.7%, X 2=14.530, p=0.001), unemployed women (36.1%, X 2=13.278, p=0.0013), and nulliparous women [36.4%, X 2 (for trend) = 4.805, p=0.0274), while there was no significant difference in the prevalence of BV with relation to trimester of pregnancy (X 2=2.750, p=0.253). Conclusion: This study reveals a relatively high prevalence of BV and significant association with factors such as age group, education and occupational status among pregnant women attending NAUTH Nnewi. Regular screening of women for BV prenatally may enable appropriate interventions to prevent adverse pregnancy outcomes

Resultado perinatal y obstétrico en embarazadas mayores a 35 años y menores a 15 años: (Estudio descriptivo retrospectivo. realizado en el Departamento de Ginecoobstetricia del hospital General San Juan de Dios) / Perinatal and obstetric outcome in pregnant women older than 35 years and younger than 15 years: (Retrospective descriptive study. Performed in the Department of Gynecology and Obstetrics of the Hospital General San Juan de Dios)

En Guatemala, el embarazo en la adolescencia es un problema social, que repercute seriamente en el desarrollo de los adolescentes. El fenómeno se vincula, directamente, con los factores económicos y, sobre todo, con el acceso a la educación y la información, aspectos que de ser accesibles ayudarían a promover un cambio favorable entre las personas con menos recursos. La edad avanzada en el embarazo representa un factor de riesgo de morbimortalidad materna, perinatal e infantil. Se realizo un Estudio descriptivo retrospectivo, se revisaron las papeletas médicas de todas las pacientes embarazadas que cumplieron con los criterios de inclusión. Dentro del estudio se incluyeron 289 pacientes, se observó mayor prevalencia de pacientes >35 años, respecto a los antecedentes prenatales, la edad gestacional más prevalente fue 37 a 41 semanas, el promedio de número de citas de control prenatal fue de 2.98, las complicaciones más frecuentes fueron infección y trabajo de parto pretérmino. En cuanto a los antecedentes natales, la Cesárea trans peritoneal fue la vía de resolución más prevalente y la asfixia perinatal fue la complicación más frecuente. Se observó asociación estadísticamente significativa entre complicaciones pre, natales y post natales edad materna mayor a 35 años. El hallazgo de sobrepeso y obesidad en pacientes mayores a 35 años se puede asociar con la prevalencia de complicaciones y el bajo promedio del número de controles prenatal. La falta de asociación entre edad materna menor a 15 años y complicaciones puede ser atribuida a que estas pacientes llevan un mejor control prenatal, debido al seguimiento especializado que se cuenta por parte del MSPAS.

In Guatemala, teenage pregnancy is a social problem, which seriously affects the development of adolescents. The phenomenon is directly linked to economic factors and, above all, to access to education and information, aspects that if accessible would help promote a favorable change among people with fewer resources. Advanced age in pregnancy represents a risk factor for maternal, perinatal and infant morbidity and mortality. A retrospective descriptive study was carried out, the medical records of all pregnant patients who met the inclusion criteria were reviewed. The study included 289 patients, a higher prevalence of patients> 35 years of age was observed, with respect to prenatal history, the most prevalent gestational age was 37 to 41 weeks, the average number of prenatal control appointments was 2.98, complications the most frequent were infection and preterm labor. Regarding the natal history, trans peritoneal caesarean section was the most prevalent means of resolution and perinatal asphyxia was the most frequent complication. A statistically significant association was observed between prenatal and postnatal complications, maternal age greater than 35 years. The finding of overweight and obesity in patients older than 35 years can be associated with the prevalence of complications and the low average number of prenatal check-ups. The lack of association be-tween maternal age less than 15 years and complications can be attributed to the fact that these patients have better prenatal control, due to the specialized follow-up provided by the MSPAS.

Concordance Between Clinical and Laboratory Diagnosis of Abnormal Vaginal Discharge in Chilean Women / Concordância entre o diagnóstico clínico e laboratorial de corrimento vaginal anormal em mulheres chilenas

Abstract Objective To determine the concordance between the clinical diagnosis of women with abnormal vaginal discharge (AVD) and laboratory results using molecular detection and observation of the vaginal microbiota. Methods Cross-sectional study conducted in 2018 in Temuco, Chile. A total of 25 midwives from 12 health centers participated. A total of 125 women>18 years old, volunteers, were recruited. The sample of the posterior vaginal fornix was obtained by speculoscopy. Characteristics of the discharge and of the external and internal genitalia were observed. Gram staining was used to observe vaginal microbiota, blastoconidia and pseudohyphae, and polymerase chain reaction was used for the detection of Trichomonas vaginalis and Candida albicans. The Cohen kappa coefficient was used in the concordance analysis. Results Out of a total of 125 women with AVD, 85.6% consulted spontaneously and 14.4% were diagnosed clinically during a routine check-up. Absolute concordance was significant (p=0.0012), with an agreement of 13.6%. The relative concordance was significant, but fair for bacterial vaginosis (Kappa=0.21; p=0.003) and candidiasis (Kappa=0.22; p=0.001), and slight for trichomoniasis (Kappa=0.14; p=0.009). The percentage of coincidence of the diagnoses (single or mixed) by laboratory and midwives was: bacterial vaginosis 63.2% (12/19), candidiasis 36.5% (27/74), and trichomoniasis 12.5% (4/32). There was 20% coinfection. A total of 36% of the clinical diagnoses of AVD had negative laboratory tests. Conclusion The vulvovaginitis conditions candidiasis and trichomoniasis appear to be overdiagnosed, and bacterial vaginosis appears to be underdiagnosed by the clinical diagnosis when compared with the laboratory diagnosis. The low concordance obtained shows the importance of complementing the clinical diagnosis with a laboratory study of AVD, particularly in women with failed treatments and/or coinfections with unspecific and varying signs and symptoms.

A concordância absoluta foi significativa (p=0,0012), com concordância de 13,6%. A concordância relativa foi significativa, mas razoável para vaginose bacteriana (Kappa =0,21; p=0,003) e candidíase (Kappa=0,22; p=0,001), e leve para tricomoníase (Kappa=0,14; p=0,009). O percentual de coincidência dos diagnósticos (solteiros ou mistos) por laboratório e parteiras foi: vaginose bacteriana 63,2% (12/19), candidíase 36,5% (27/74) e tricomoníase 12,5% (4/32). Houve 20% de coinfecção. Umtotal de 36% dos diagnósticos clínicos de AVD tiveram exames laboratoriais negativos. Conclusão As condições de vulvovaginite candidíase e tricomoníase parecem ser sobrediagnosticadas, e a vaginose bacteriana parece ser subdiagnosticada pelo diagnóstico clínico quando comparado com o diagnóstico laboratorial. A baixa concordância obtida mostra a importância de complementar o diagnóstico clínico comestudo laboratorial de AVD, principalmente emmulheres com falha de tratamento e / ou coinfecções com sinais e sintomas inespecíficos e variáveis.

Vaginal microbiota transplantation for treatment of bacterial vaginosis: a review / 生物工程学报

Bacterial vaginosis (BV) is a disease caused by vaginal microbiota dysbiosis. The conventional antibiotic treatment can aggravate microbial dysbiosis, alter the acid environment of the vagina and lead to drug resistance, thus shows low cure rate and high recurrence rate. This poses significant physiological and psychological burden to the BV patients. Vaginal microbiota transplantation (VMT) is a novel live biotherapeutic approach. It directly engrafts the whole vaginal microbiota from healthy women to the vaginal tract of patients to rapidly reconstruct the vaginal microbiota environment and restore the vaginal health. This article summarizes the development, present challenges, and future directions of using VMT, with the aim to explore new strategies for treatment of BV and promote the clinical use of VMT.

Impact of HPV infection on vaginal microecology and maternal and neonatal outcomes / 中南大学学报(医学版)

OBJECTIVES@#Human papillomavirus (HPV) is a kind of spherical DNA virus, which is related to many factors such as immune status and pregnancy. Due to the decrease of immunity, pregnant women are more likely to have HPV infection, which causes serious imbalance of vaginal microecology and is not beneficial to pregnancy outcome. Therefore, this study focuses on the impact of HPV infection on vaginal microecology and maternal and neonatal outcomes.@*METHODS@#A total of 140 pregnant women with HPV infection during pregnancy, who received obstetric examination in the First Affiliated Hospital of Hainan Medical College from November 2017 to July 2019, were selected as a HPV infection group, and 150 normal pregnant women with HPV negative in the same period were selected as a control group. Vaginal secretions were collected from all the pregnant women at 28-34 weeks of gestation to evaluate vaginal pH, cleanliness and microecological status, and to record pregnancy outcomes for all pregnant women.@*RESULTS@#The proportions of vaginal pH>4.5, constituent ratio of flora density and diversity of I-II, positive detection rate of vulvovaginal candidiasis (VVC) and bacterial vaginosis (BV) in HPV infected pregnant women were significantly higher than those in the control group (all @*CONCLUSIONS@#Pregnant women with HPV infection during pregnancy are more likely to have vaginal microecological disorders, and can increase the risk of adverse pregnancy outcomes such as premature delivery and chorioamnionitis.

Laboratorial aspects of cytolytic vaginosis and vulvovaginal candidiasis as a key for accurate diagnosis: a pilot study / Aspectos laboratoriais da vaginose citolítica e candidíase vulvovaginal como uma chave para o diagnóstico preciso: Um estudo piloto

Abstract Objective To identify clinical, microscopic, and biochemical characteristics that differentiate cytolytic vaginosis (CV) from vulvovaginal candidiasis (VVC). Methods The present cross-sectional study analyzed the vaginal contents of 24 non-pregnant women aged 18 to 42 years who were attended at the Genital Infections Clinic at Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). They were diagnosed either with (CV = 8, VVC = 8) or without vulvovaginitis or vaginal dysbiosis (controls). The socio-demographic, clinical, and gynecological data were obtained from a detailed patient interview. Samples of the vaginal contents were collected for analysis of vaginal pH, gram stain, and specific fungal culture. The Kruskal-Wallis and Fisher exact tests were used to compare the differences between the groups. Odds ratios were used to compare the categorical variables. The significance level was considered at p < 0.05. Results Both women with CV and VVC had a lumpy vaginal discharge (p = 0,002) and vaginal hyperemia (p = 0.001), compared with controls. The inflammatory process was more intense in the VVC group (p = 0.001). In the CV group, there was statistical significance for the lactobacillus amount (p = 0.006), vaginal epithelium lysis (p = 0.001), and vaginal pH (p = 0.0002). Conclusion Cytolytic vaginosis and VVC diagnoses rarely differ on clinical characteristics but have different laboratorial findings. The present study highlights the importance of conducting an accurate investigation through laboratory tests rather than clinical criteria to avoid misdiagnosis.

Resumo Objetivo Identificar características clínicas, microscópicas e bioquímicas que diferenciam a vaginose citolítica (VC) da candidíase vulvovaginal (CVV). Métodos O presente estudo de corte transversal analisou o conteúdo vaginal de 24 mulheres não grávidas, com idades entre 18 e 42 anos, atendidas no ambulatório de Infecções Genitais do Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). Elas foram diagnosticadas com (CV = 8, CVV = 8) ou sem vulvovaginite ou disbiose vaginal (controles = 8). Os dados sociodemográficos, clínicos e ginecológicos foram obtidos em uma entrevista detalhada do paciente. Amostras do conteúdo vaginal foram coletadas para análise do pH vaginal, coloração de Gram e cultura específica de fungos. Os testes exatos de Kruskal-Wallis e Fisher foram utilizados para comparar as diferenças entre os grupos. A razão de chances foi utilizada para comparar as variáveis categóricas. O nível de significância considerado foi de p < 0,05. Resultados As mulheres com VC e CVV apresentaram corrimento vaginal irregular (p = 0,002) e hiperemia vaginal (p = 0,001), em comparação aos controles. O processo inflamatório foi mais intenso no grupo CVV (p = 0,001). No grupo VC, houve significância estatística para a quantidade de lactobacilos (p = 0,006), lise do epitélio vaginal (p = 0,001) e pH vaginal (p = 0,0002). Conclusão Os diagnósticos de VC e CVV raramente diferem nas características clínicas, mas apresentam achados laboratoriais diferentes. O presente estudo destaca a importância de conduzir uma investigação precisa por meio de testes laboratoriais, em vez de critérios apenas clínicos, a fim de evitar erros de diagnóstico.

Infecciones cervicovaginales en exudados vaginales / Cervicovaginal infections in vaginal exudates

Introducción: Se desconocen las características de las infecciones cervicovaginales, diagnosticadas mediante el exudado vaginal, sobre todo en mujeres cubanas de mediana edad. En otras etapas del ciclo vital femenino, sí se han realizado estos estudios. Esta información es importante, fundamentalmente para realizar acciones de promoción de salud. Objetivo: Determinar las características de las infecciones cervicovaginales más frecuentes diagnosticadas mediante el exudado vaginal. Método: Se realizó un estudio transversal en 1118 mujeres. Se recogió la edad (agrupada en 20 - 44 años y 45 y más años), los resultados del exudado vaginal, la percepción de secreción vaginal o la ausencia de esta (asintomáticas) y los microorganismos identificados en el exudado. Resultados: El 49,9 por ciento de exudados vaginales fueron positivos a vaginosis bacteriana, Cándidas albicans, Trichomonas vaginalis y desequilibro en la ecología vaginal. El 45 por ciento de las pacientes no tenían secreción vaginal, es decir, estaban asintomáticas. Conclusión: Las infecciones cervicovaginales se caracterizaron por ser de elevada frecuencia, usualmente asintomáticas, con predominio de vaginosis bacteriana, candidiasis y trichomoniasis(AU)

ABSTRACT Introduction: The characteristics of cervicovaginal infections diagnosed by vaginal exudate are unknown, especially in middle-aged Cuban women. At other stages of the female life cycle, these studies have been done. Due to the importance of this information, to carry out health promotion actions, this research was carried out. Objective: To determine the characteristics of the most frequent cervicovaginal infections diagnosed by vaginal exudate. Method: A cross-sectional study was conducted in 1118 women. Age (grouped into 20-44 years and 45 and over), the results of positive vaginal discharge, the perception of presence or not of vaginal discharge (asymptomatic) and the microorganisms identified in the discharge were collected. Results: 49.9 percent of vaginal exudates were positive for bacterial vaginosis, Candidas albicans, Trichomonas vaginalis and imbalance in vaginal ecology. 45 percent of the patients had no vaginal discharge, that is, they were asymptomatic. Conclusion: Cervicovaginal infections were characterized by being of high frequency, usually asymptomatic, with prevalence of bacterial vaginosis, candidiasis and trichomoniasis(AU)

Bacterial vaginosis: prevalence, risk profile and association with sexually transmitted infections / Vaginose bacteriana: prevalência, perfil de risco e associação com infecções sexualmente transmissíveis / Vaginosis bacteriana: prevalencia, perfil de riesgo y asociación con infecciones de transmisión sexual

Background and Objectives: Bacterial vaginosis (BV) is the most common cause of vaginal discharge in the world. The study aimed to estimate the prevalence and to identify risk factors associated with bacterial vaginosis. Methods: A cross-sectional study was conducted in Ouro Preto, Brazil, between February and December 2017. Three hundred and forty-one women aged 18 years or older, users of the Brazilian Unified Health System, participated in this study. Women who used oral or topical antibiotics in the four weeks prior to the sample collection and women who had undergone a total hysterectomy were excluded from the study. After signing the Informed Consent Form and filling out a questionnaire containing sociodemographic, behavioral and sexual data, the participants were directed to the collection room, where the nurse collected the samples for the preventive examination of the cervix and also two vaginal swabs. Vaginal swabs and cervical samples were analyzed for cytological abnormalities and BV using Gram staining and cytology. Pathogens causing sexually transmitted infections (STIs) were identified by Polymerase Chain Reaction (PCR). For the analysis of the data, statistical package STATA version 10.0 was used. This study was approved by the Research Ethics Committee of the Federal University of Ouro Preto (UFOP). Results: During the study, 341 women were evaluated. The prevalence of BV using Gram staining (32.5% [CI95% 27.7-37.7%]) and cytology (27.7% [CI95% 23.032.8%]) was similar, however, the sensitivity of cytology was lower (77.8%). Risk factors associated with BV were smoking (IRR 1.5 [CI95%: 1.1  2.1]), use of an intrauterine device (IRR 2.8 [CI95%: 1.2 - 6.5]), and past medical history of BV (IRR 1.5 [CI95%: 1.1 - 2.1]). Correlation between the presence of BV and Trichomonas vaginalis (TV) infection (r=0.24) was observed. Conclusion: The prevalence of BV was affected by life habits and was prevalent in women with TV. Thus, behavioral and social prevention approaches to women with diverse risk profiles may help mitigate TV/BV prevalence and recurrence of BV.(AU)

Contexte et objectifs: La vaginose bactérienne (VB) est la cause la plus fréquente de pertes vaginales dans le monde. Le but de cette étude était d'évaluer la prévalence et les facteurs associés à la vaginose bactérienne. Méthodes: Il s'agit d'une approche descriptive, transversale et quantitative réalisée à Ouro Preto, Minas Gerais, Brésil, entre février et décembre 2017. 341 femmes ont participé à cette étude, âgées de 18 ans ou plus, utilisatrices du Système de santé unifié. Les femmes ayant utilisé des antibiotiques oraux ou topiques dans les quatre semaines précédant le prélèvement et les femmes ayant subi une hystérectomie totale ont été exclues de l'étude. Après avoir signé le formulaire de consentement éclairé et rempli un questionnaire contenant des données sociodémographiques, comportementales et sexuelles, les participants ont été dirigés vers la salle de collecte, où l'infirmière a prélevé les échantillons pour l'examen préventif du col de l'utérus. et aussi deux écouvillons vaginaux. Les échantillons de frottis vaginaux et cervicaux ont été analysés pour les anomalies cytologiques et VB en utilisant la coloration de Gram et la cytologie. Les agents pathogènes causant des infections sexuellement transmissibles (IST) ont été identifiés par réaction en chaîne par polymérase. Pour l'analyse des données, le progiciel statistique STATA version 10.0 a été utilisé. Cette étude a été approuvée par le Comité d'éthique de la recherche de l'Université fédérale d'Ouro Preto (UFOP). Résultats: Au cours de l'étude, 341 femmes ont été évaluées. La prévalence de la VB avec coloration de Gram (32,5% [IC 95% 27,7 - 37,7%]) et de la cytologie (27,7% [IC 95% 23,0 - 32,8%]) était similaire, cependant la sensibilité cytologique était plus faible (77,8%). Les facteurs de risque associés à la VB étaient le tabagisme (IRR 1,5 [IC 95%: 1,1 - 2,1]), l'utilisation d'un dispositif intra-utérin (IRR 2,8 [IC 95%: 1,2 - 6,5] ) et antécédents médicaux de VB (IRR 1,5 [IC 95%: 1,1 - 2,1]). Il y avait une corrélation entre la présence d'une infection à VB et Trichomonas vaginalis (TV) (r = 0,24). Conclusion: La prévalence de la VB était affectée par le mode de vie et l'infection TV. Ainsi, les approches de prévention comportementale et sociale pour les femmes présentant des profils de risque différents peuvent aider à atténuer la prévalence de la TV / VB et la récurrence de la VB.(AU)

Justificativa e Objetivos: A vaginose bacteriana (VB) é a causa mais comum de corrimento vaginal no mundo. O objetivo desse estudo foi avaliar a prevalência e os fatores associados à vaginose bacteriana. Métodos: Trata-se de um descritivo, de forma transversal e abordagem quantitativa realizado em Ouro Preto, Minas Gerais, Brasil, entre fevereiro a dezembro de 2017. Participaram desse estudo 341 mulheres com idade igual ou superior a 18 anos, usuárias do Sistema Único de Saúde (SUS). Mulheres que usaram antibióticos orais ou tópicos nas quatro semanas anteriores à coleta e mulheres que haviam sido submetidas a uma histerectomia total foram excluídas do estudo. Após a assinatura do Termo de Consentimento Livre e Esclarecido e preenchimento de questionário contendo dados sócio-demográfico, comportamental e sexual, as participantes foram encaminhadas para a sala de coleta, onde a enfermeira realizou a coleta das amostras para o exame preventivo do colo do útero e também de dois swabs vaginais. As amostras de esfregaço vaginal e cervical foram analisadas quanto às anormalidades citológicas e VB usando coloração de Gram e citologia. Patógenos causadores de infecções sexualmente transmissíveis (ISTs) foram identificados por Reação em Cadeia da Polimerase (PCR). Para a análise dos dados foi utilizado o pacote estatístico STATA versão 10.0. O presente estudo foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Ouro Preto (UFOP). Resultados: Durante o estudo, 341 mulheres foram avaliadas. A prevalência de VB com coloração de Gram (32,5% [IC95% 27,7 - 37,7%]) e citologia (27,7% [IC95% 23,0 - 32,8%]) foi semelhante, porém a sensibilidade da citologia foi menor (77,8%). Os fatores de risco associados ao VB foram tabagismo (IRR 1,5 [IC95%: 1,1 - 2,1]), uso de dispositivo intrauterino (IRR 2,8 [IC 95%: 1,2 - 6,5]) e história médica pregressa de VB (IRR 1,5 [IC95%: 1,1 - 2.1]). Observou-se correlação entre a presença de infecção por VB e Trichomonas vaginalis (TV) (r = 0,24). Conclusão: A prevalência de VB foi afetada por hábitos de vida e infecção por TV. Assim, abordagens de prevenção comportamental e social para mulheres com diversos perfis de risco podem ajudar a mitigar a prevalência de TV / VB e recorrência de VB.(AU)

The influence of genitalis odors to women's life / A influência dos odores de genitais na vida da mulher

Objective: To study current knowledge about genital odors by narrative review and suggest a scientifically validated approach to the problem. Methods: Narrative review taking into account articles published in the last 15 years. Results: Vaginal infections and/or dysbioses are the main causes of bad genital odor, with bacterial vaginosis (BV) being the most frequent finding. The change in the body's smell can be caused by several factors that include everything from food to stress. As the cases of vaginal dysbioses are becoming more and more frequent and the treatments usually recommended do not always solve the problem, the use of vaginal acidifiers has become more recurrent to rebalance the vulvovaginal pH. Despite this, there is not yet a scientifically validated approach to identifying the cause of the odor. Conclusion: Female genital malodor affects women's quality of life and should be investigated and treated accordingly

Objetivo: Estudar por revisão narrativa os conhecimentos atuais sobre odores genitais e sugerir uma forma de abordagem do problema que seja cientificamente validada. Métodos: Revisão narrativa levando em conta artigos publicados nos últimos 15 anos. Resultados: As infecções e/ou disbioses vaginais são as principais causas do mau odor genital, sendo principalmente a vaginose bacteriana (VB) o achado mais frequente. A alteração no cheiro do corpo pode ser provocada por uma série de fatores que incluem desde a alimentação até o estresse. Como a ocorrência de casos de disbioses vaginais vem se tornando cada vez mais frequente e os tratamentos habitualmente recomendados nem sempre resolvem o problema, vem se tornando mais recorrente o uso de acidificantes vaginais com a finalidade de reequilibrar o pH vulvovaginal. Apesar disso, não há ainda um forma de abordagem e de identificação da causa do odor que seja cientificamente validada. Conclusão: O mau odor genital feminino afeta a qualidade de vida das mulheres e deve ser investigado e tratado adequadamente.
