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.

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

Factors associated with bacterial vaginosis in women with homosexual, bisexual and heterosexual practices

Abstract Background The factors associated with bacterial vaginosis in women with homosexual, bisexual and heterosexual practices are still poorly explored. Thus, the aim of this study was to analyze the factors associated with bacterial vaginosis in women with different sexual practices. Methods Cross-sectional study that included 453 women, 149 Women with Homosexual practice (WSW); 80 bisexual Women (WSWM) and 224 Women with heterosexual practice (WSM). The diagnosis of bacterial vaginosis was performed by microscopic examination of the vaginal smears stained by Gram method and classified according to the Nugent et al. (1991) score. Data analysis was performed by Cox multiple regression. Results Bacterial vaginosis was associated to years of education among WSW (0.91 [95% CI 0.82‒0.99]; p= 0.048) and non-white skin color (2.34 [95% CI 1.05‒5.19]; p= 0.037) between WSWM. Changing partners in the last 3-months (2.09 [95% CI 1.14‒3.82]; p= 0.017), inconsistent use of condoms (2.61 [95% CI 1.10‒6.20]; p= 0.030) and positive diagnosis of Chlamydia trachomatis (2.40 [95% CI 1.01‒5.73]; p= 0.048) were associated with bacterial vaginoses only in WSH. Conclusions The factors associated to bacterial vaginosis differ between different sexual practices, suggesting that the type of sexual partner may influence the risk of developing this classic dysbiosis.

Sexually transmitted infections （STIs） and related factors among pregnant women with non-local household registration in Xuhui District， Shanghai / 上海预防医学

ObjectiveTo study the sexually transmitted infections （STIs） in pregnant women with non-local household registration in Xuhui District and analyze the risk factors for STIs. MethodsFrom April 2020 to March 2022， pregnant women with non-local household registration who received their first prenatal examination in a general hospital in Shanghai Xuhui District were selected to conduct a status survey of STIs. Logistic regression model was used to analyze the influencing factors of bacterial vaginitis and ureaplasma uaplasma infection. ResultsThe top three infection rates in the pregnant women were Ureaplasma urealyticum （13.2%）， bacterial vaginosis （9.8%） and mycotic vaginitis （4.7%）. Age between 25 and 35 years （aOR=0.53，95%CI： 0.28‒0.98） and monthly income ≥8 000 yuan （aOR=0.30，95%CI： 0.11‒0.82） were significantly correlated with ureaplasma uaplasma infection. Pregnancy number of 2 （aOR=4.95， 95%CI： 1.59‒15.46）， first sexual relationship occurred before marriage （aOR=2.83， 95%CI： 1.04‒7.74）， husband's alcoholism （aOR=3.83， 95%CI： 1.08‒13.56）， high school education （aOR=0.27， 95%CI： 0.08‒0.93）， and husband's travel history （aOR=0.30， 95%CI： 0.12‒0.79） were significantly correlated with bacterial vaginitis. ConclusionPregnant women with more gestation times， first sexual intercourse before marriage and husband with heavy drinking are more likely to be infected with bacterial vaginosis. Pregnant women with younger age and lower income are more likely to be infected with Ureaplasma urealyticum. Follow-up and monitoring should be strengthened in these groups.

Factors associated with Trichomonas vaginalis infection in reproductive-aged women attending cervical screening in southeast of Brazil

ABSTRACT Background: Sexually Transmitted Infections (STIs) can be caused by viruses, bacteria, and parasites. The World Health Organization estimated more than 300 million new global cases of curable STIs among individuals of reproductive age. Infection by Trichomonas vaginalis is one of the most prevalent curable STL Despite the current treatments available, the diagnosis of T. vaginalis can be difficult, and the resistance to the treatment increased concern for the healthcare system. Objectives: The aim of this study was to determine the prevalence and factors associated with Trichomonas vaginalis infection among women of reproductive age attending community-based services for cervical screening. Patients and methods: A total of 1477 reproductive-aged women attending 18 Primary Health Care Units in Botucatu, Brazil, from September to October 2012, were enrolled. A structured questionnaire was used for individual face-to-face interviews for obtaining data on sociodemographic, gynecologic, and obstetrics history, sexual and hygiene practices, among others. Cervicovaginal samples were obtained for detection of T. vaginalis by culture using Diamond's medium and microscopic vaginal microbiota classification according to Nugent. A multivariable logistic regression analysis was carried out to estimate Odds Ratios (OR) and 95% Confidence Intervals (95% CI) for the association between participants' sociodemographic, behavioral factors, and clinical factors with T. vaginalis infection. Results: Median age of study participants was 33 years (ranging from 18 to 50). The overall prevalence of T. vaginalis infection was 1.3% (n = 20). Several factors were independently associated with T. vaginalis infection, such as self-reporting as black or Pardo for ethnicity (OR = 2.70; 95% CI 1.03-7.08), smoking (OR=3.18; 95% CI 1.23-8.24) and having bacterial vaginosis (OR = 4.01; 95%CI = 1.55-10.38) upon enrollment. A protective effect of higher educational level (having high school degree) was observed (OR = 0.16; 95% CI 0.05-0.53). Conclusions: Our data suggest that screening programs to correctly detect T. vaginalis infection can be helpful to guide prevention strategies to the community. Our study supports an association between abnormal vaginal microbiota and T. vaginalis infection.

Risk Factors Associated with Bacterial Vaginosis in Pregnant Women in Senegal

Background: Bacterial vaginosis (BV) is associated with a high risk of complications, particularly during pregnancy. Objectives: The aims of this study were to determine the prevalence of BV in pregnant women in Dakar, Senegal, and to identify its associated risk factors. Patients and Methods: This prospective cross-sectional study was conducted from July 2020 to March 2021 in pregnant women with 34 to 38 weeks of gestation and seen for their routine prenatal consultation at the Nabil Choucair health center in Dakar, Senegal. Vaginal swabs were taken and examined using the Nugent scoring system for the diagnosis of the BV. Data analysis on SPSS (version 25) was done using the chi-square test to measure the strength of association. A value of p ? 0.05 was considered statistically significant. Results: BV was found in 28.0% (112/400) of the screened women with a median age 24 (21-29) years. A pH >4.5 predictive of BV was found in 80.4% (90/112) of samples. BV was associated with vaginal candidiasis in 49.1% (55/112) while Trichomonas vaginitis was found in 1.8% (02/112). In 80.4% (90/112) of affected women, BV was caused by Gardnerella vaginalis. Mobiluncus spp. was found in 19.6% (22/112) pregnant women in association with G. vaginalis. Symptoms characterized by episodes of pruritus, pelvic pain, burning and/or dyspareunia were seen among 59.8% (67/112) of these women with BV while 40.1% (45/112) of them reported no symptoms. Conclusion: In view of these results and in order to reduce gestational complications and adverse outcomes in the newborn, screening for BV in pregnant women should be favored in developing countries.

Resultados . Todas las cepas de referencia ATCC tuvieron un alto nivel de susceptibilidad al extracto, con excepción de P. vibia, V. parvula y L. crispatus. Interesantemente, los aislamientos clínicos de G. vaginalis y la cepa ATCC de G. vaginalis fueron los más susceptibles al extracto dados los bajos valores de CMI (1,0 - 2,0 mg/mL) y CBM (1,0 - 4,0 mg/mL), mientras que, los aislamientos clínicos de Lactobacillus spp. y la cepa ATCC de L. crispatus fueron los menos susceptibles debido a los altos valores de CMI (32,0 mg/mL) y CBM (≥ 32,0 mg/mL). Conclusiones . Los experimentos in vitro sugieren que el extracto posee propiedades antibacterianas selectivas dada su alta actividad contra bacterias anaerobias asociadas a vaginosis bacteriana y baja actividad contra especies de Lactobacillus.

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.

Study Of Association Between Vaginal Infection And Preterm Labour

Background:Preterm birth is the most common of neonatal morbidity and mortality. 85% of neonatal morbidity and mortality is due to premature birth. A large number of studies demonstrate an association between specific organisms and preterm delivery. Material And Methods:A retrospective cohort study of pregnant women who received antenatal care between august 2017 and November 2018 at our tertiary care hospital. 70 Cases with high risk for preterm labor were included in the study and 70 cases with term labor in the control group. High vaginal swabs were collected from the posterior fornix of the vagina. Result:This study shows that there is no association of preterm labor with age, parity and numbers of previous abortions. There are high chances of preterm birth in patients with history of previous preterm birth. 48(68%) patients with preterm labor had vaginal infection in which bacterial vaginosis is more common. Other contributing factors for preterm delivery: Anaemia and lower socio-economic status. Conclusion:In this study, a significant difference in the presence of vaginal infection in patients of preterm labor and term labor was found (P<0.05).Women at risk for preterm birth or preterm premature rupture of membranes because of vaginal infections should be screened, diagnosed, treated , reevaluated, and re-treated if necessary.

Utility of Vaginal pH as Point of Care Test for Detection of Bacterial Vaginosis

Background & objectives: Bacterial vaginosis (BV) is a Reproduc?ve tract infec?on (RTI) among young sexually ac?ve women with high prevalence. It is associated with complica?ons related to pregnancy and an increased risk of acquiring STDs. This poses a need for cost-effec?ve detec?on of BV in low resource se?ngs. Hence, we propose to study the u?lity of vaginal pH determina?on for the detec?on of BV. Material & Methods: This is a single center, 1 year cross-sec?onal study. Swabs were collected from 250 non-pregnant women a?ending the out-pa?ent department of Obstetrics and Gynecology with vaginal discharge as a predominant symptom with or without backache and abdominal pain. Vaginal pH determina?on, Gram stain, wet mount, Whiff test, and Amsel’s criteria were used for BV detec?on. Results: 250 study par?cipants with vaginal discharge sugges?ve of BV were analyzed. Vaginal pH was significantly higher in women with BV with the mean pH being 6.2. Vaginal pH >4.5 had a sensi?vity of 85% and specificity of 66% to detect BV. The Whiff test had the least sensi?vity. Clue cells and Amsel’s criteria of ? 3 were significant for BV. A combina?on of pH and Whiff test performed be?er had high sensi?vity and specificity. Conclusions: A combina?on of pH determina?on and the Whiff test serves as a low-cost alterna?ve in resource-poor se?ngs for detec?on of BV. Though Clue cells and Amsel’s criteria ? 3 were most sensi?ve and specific, they cannot be used in low resource se?ngs. Vaginal pH alone can be used to detect BV in areas of low prevalence.

STUDY OF BACTERIAL VAGINOSIS IN PREGNANCY

AIM Ÿ To screen and diagnose bacterial vaginosis during first two trimesters of pregnancy. Ÿ To give early treatment for bacterial vaginosis during first two trimesters of pregnancy and prevent obstetric complications. METHODS – Pregnant women fitting in the inclusion criteria are recruited and explained about the procedure. Informed consent and ethics committee clearance is obtained. Vaginal smear is sent for microscopy. Vaginal pH is detected. Amine (fishy) odour in wet mount examination is identified. AMSELS score and NUGENTS criterion are applied. Positive specimens are sent for antibiotic culture and sensitivity and treatment is initiated accordingly. Afollow up is kept for all patients diagnosed as bacterial vaginosis to see the outcome of their pregnancy. CONCLUSION - Prevalence of Bacterial vaginosis in my study is 29.2%. BV in pregnancy is common among low socioeconomic status, multigravida, and less educated females. It is associated with significant risk of miscarriages, preterm labour and PROM. Universal screening of all pregnant women at booking visit may be recommended to initiate treatment with metronidazole / clindamycin in those women at risk for preterm delivery, symptomatic women and before surgical abortions.

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

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.

Resumo Objetivo Determinar a concordância entre o diagnóstico clínico de mulheres com corrimento vaginal anormal (AVD) e os resultados laboratoriais por meio da detecção molecular e observação da microbiota vaginal. Métodos Estudo transversal realizado em 2018 em Temuco, Chile. Participaram 25 parteiras de 12 centros de saúde. Um total de 125 mulheres>18 anos, voluntárias, foramrecrutadas. A amostra do fórnice vaginal posterior foi obtida por especuloscopia. Foram observadas características da secreção e da genitália externa e interna. A coloração de Gram foi usada para observar a microbiota vaginal, blastoconídios e pseudo-hifas, e a reação em cadeia da polimerase foi usada para a detecção de Trichomonas vaginalis e Candida albicans. O coeficiente kappa de Cohen foi usado na análise de concordância. Resultados De um total de 125 mulheres com AVD, 85,6% consultaram espontaneamente e 14,4% foram diagnosticados clinicamente durante um check-up de rotina. 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.

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.
