Análisis microbiológico del tracto genital materno y de la sangre del cordón umbilical en relación con el daño neonatal / Microbiological analysis of the maternal genital tract and umbilical cord blood and its association with neonatal damage

La etiología que conduce al daño neonatal es multifactorial, y los procesos infecciosos pueden estar implicados en él. El objetivo de este estudio fue identificar microorganismos del tracto genital materno asociados con el daño neonatal, a fin de prevenir futuras complicaciones perinatológicas. Se estudiaron 711 embarazadas que concurrieron entre enero de 2010 y julio 2013 al consultorio externo de Obstetricia del Hospital de Clínicas de la UBA para sus controles prenatales, y cuyos partos también tuvieron lugar en dicho nosocomio. En la sangre del cordón umbilical se investigó la presencia de Ureaplasma urealyticum y Mycoplasma hominis mediante el cultivo con sustratos metabólicos (Micofast-Biomerieux), y la de Trichomonas vaginalis por PCR, con primers específicos. El estudio microbiológico del contenido vaginal se efectuó en 288 de las embarazadas en la semana 35 a 37. Se empleó la metodología convencional, a la que se agregó el cultivo en tioglicolato modificado para T. vaginalis. Se investigó la presencia de estreptococos grupo B (EGB) en hisopado anorrectaly de introito vaginal, utilizando enriquecimiento en caldo selectivo y posterior siembra en medio cromogénico. Se utilizaron los test de χ² Yates y de Fisher para muestras independientes, considerándose significativo p < 0,05. La vaginosis bacteriana (VB) se relacionó significativamente con el daño neonatal (p = 0,02), al igual que la presencia de M. hominis (p = 0,03) y de T. vaginalis (p = 0,03) en la sangre del cordón umbilical. Las complicaciones predominantes fueron el parto pretérmino, la rotura prematura de membrana (RPM), el bajo peso y un valor de Apgar <7. No se asoció al daño neonatal la presencia de U. urealyticum (p = 0,35) en el cordón umbilical, ni la de Candidaspp. (p = 0,94) o EGB (p = 0,18) en el tracto genital de las madres. Dado que ciertas alteraciones en la microbiota del tracto genital materno se relacionaron con el dano neonatal, consideramos de fundamental importancia realizar el estudio microbiológico del contenido vaginal durante el embarazo, para prevenir posibles complicaciones maternas y perinatológicas.

The etiology leading to neonatal damage is multifactorial, being genital infections one of the causes. The objective of the study was to identify microorganisms of the maternal genital tract that are associated with neonatal damage, in order to prevent future perinatal complications. Seven hundred and eleven pregnant patients attended their prenatal control during the period January 2010-July 2013. Ureaplasma urealyticum and Mycoplasma hominis presence was investigated in umbilical cord blood by metabolic substrates (Micofast-Biomerieux) and that of T. vaginalis, by PCR using specific primers. The microbiological study of the vaginal contents of 288 pregnant patients at weeks 35 to 37 was performed by conventional methods, adding the modified thioglycolate culture for T. vaginalis. Group B streptococcus (GBS) was investigated in anorectal and vaginal introitus swabs, using selective broth enrichment and subsequent isolation in chromogenic medium. The χ² Yates test and Fisher's test were used for independent samples. A p value <0.05 was considered statistically significant. The pathogens significantly related to neonatal damage were M. hominis (p = 0.03), T. vaginalis (p = 0.03), and BV (p = 0.02). Main complications were preterm birth, premature rupture of membranes (PRM), low weight and Apgar score <7. U. urealyticum (p = 0.35), Candidaspp. (p = 0.94) and GBS (p = 0.18) were not related to neonatal damage. Since different microorganisms of the maternal genital tract were related to neonatal damage, it is very important to perform the microbiological study of vaginal contents during pregnancy to prevent possible maternal and perinatal complications.

Prevalencia de disfunción vaginal en mujeres de la ciudad de Bahía Blanca (Argentina) / Vaginal dysfunction prevalence in women of the city of Bahía Blanca (Argentina) / A prevalência de disfunção vaginal em mulheres da cidade de Bahía Blanca (Argentina)

La disfunción vaginal (vaginosis/vaginitis) es la patología genital hoy reconocida más prevalente. El objetivo del trabajo fue generar información sobre la prevalencia de Disfunción vaginal y los factores de riesgo asociados en mujeres sintomáticas y asintomáticas. Se incorporó además la detección de C. trachomatis y N. gonorrhoeae. Se consolida la validez del Balance del Contenido Vaginal (BACOVA) en el diagnóstico integral de disfunción vaginal y de la amplificación génica en la detección de C. trachomatis. Se estudiaron 295 mujeres que asistieron al Hospital Municipal de Bahía Blanca. La mayor prevalencia correspondió a vaginosis bacteriana (21,36%), luego levaduras (13,90%), T. vaginalis (3,73%) y C. trachomatis (3,05%). No se detectó ningún caso de gonococia. Los factores de riesgo encuadran en el marco de valores de la región centro sur del país, pero se debe destacar la frecuencia significativa de alteraciones de la función vaginal (68,87%) y la infección por clamidias (4,35%) detectadas en mujeres asintomáticas. Esto impone la necesidad de revisar y optimizar la política de cumplimiento de las Normas Ministeriales de prevención y control con la aplicación de una metodología de laboratorio normatizada en el protocolo de control de mujeres en edad fértil, embarazadas o no.

Vaginal dysfunction (vaginosis/vaginitis) is the most prevalent genital pathology recognized today. The objective of the work was to generate information on the prevalence of vaginal dysfunction and the associated risk factors in symptomatic and asymptomatic women. The detection of C. trachomatis and N. gonorrhoeae was also incorporated. The validity of the Vaginal Content Balance (BACOVA) in the comprehensive diagnosis of vaginal dysfunction and of gene amplification in the detection of C. trachomatis is consolidated. A total of 295 women who attended the Municipal Hospital of Bahía Blanca were studied. The highest prevalence corresponded to bacterial vaginosis (21.36%), then yeasts (13.90%), T. vaginalis (3.73%) and C. trachomatis (3.05%). No cases of gonorrhea were detected. The risk factors fit within the framework of values of the south central region of the country, but the significant frequency of alterations of vaginal function (68.87%) and chlamydial infection (4.35%) detected in asymptomatic women should be noted. This imposes the need to review and optimize the compliance policy of the Ministerial Standards of prevention and control, with the application of a standardized laboratory methodology, in the control protocol for women of childbearing age, pregnant or not.

Infecciones vaginales en un Centro de Salud Familiar de la Región Metropolitana, Chile / Vaginal infections in a Family Health Clinic in the Metropolitan Region, Chile

Background: Vaginal infections are a frequent cause for consultation, but their prevalence and etiology vary in different populations. Objectives: To determine the prevalence and etiologies of vaginal infection in women attending a family health center in the Metropolitan Region of Chile. Methods: The microbiological diagnosis was made by wet mount and Gram stain. Diagnosis of trichomoniasis was performed by wet mount, culture and polymerase chain reaction. Results: 101 women aged 15-54, not selected by signs or symptoms of vaginal infection, 46 of them pregnant were included. In 47 women (46.5%), vaginal infections were diagnosed. An association was observed between age and frequency of vaginal infection. The proportion of infections among pregnant and non-pregnant women was similar. The most frequent infections were bacterial vaginosis (16.8%), vulvovaginal candidiasis (11.9%) and co-infections (6.9%). We found 5.9% of intermediate microbiota cases, 3% of trichomoniasis and 2% of aerobic vaginitis. Symptoms of vaginal infection had poor agreement with microbiological findings. Otherwise physical signs had good agreement with the presence of infection, but low to moderate concordance with a specific etiology. Conclusions: We found a high prevalence of vaginal infections in the study population. It is necessary to improve the definitions and criteria of microbiological diagnosis of co-infections and intermediate microbiota, for them to be diagnosed in the clinical practice. More descriptive questionnaires are recommended to enhance the usefulness of clinical examination.

Introducción: Las infección vaginales constituyen un motivo frecuente de consulta, pero su prevalencia y etiología varían en distintas poblaciones. Objetivos: Determinar la prevalencia y tipos de infección vaginal en mujeres atendidas en un centro de salud familiar de la Región Metropolitana. Métodos: El diagnóstico microbiológico fue efectuado mediante examen microscópico al fresco y tinción de Gram y para tricomoniasis examen al fresco, cultivo y reacción de la polimerasa en cadena. Resultados: Se incluyeron 101 mujeres de 15-54 años, no seleccionadas por signos ó síntomas, 46 de ellas embarazadas. En 47 mujeres (46,5%) se diagnosticaron infecciones vaginales. Se observó asociación entre edad y frecuencia de infección vaginal. La proporción de infecciones entre gestantes y no gestantes fue similar. Las infecciones más frecuentes fueron vaginosis bacteriana (16,8%), candidiasis vulvo-vaginal (11,9%) y co-infecciones (6,9%). Se observó 5,9% casos de microbiota intermedia, 3% de tricomoniasis y 2% de vaginitis aeróbica. Los síntomas de infección vaginal tuvieron mala concordancia con los hallazgos microbiológicos. A su vez, los signos físicos tuvieron buena concordancia con la existencia de infección, pero escasa a moderada concordancia con una etiología específica. Conclusiones: Se encontró alta frecuencia de infecciones vaginales. Es necesario mejorar las definiciones y criterios de diagnóstico microbiológico de las co-infecciones y microbiota intermedia, para ser diagnosticadas en la práctica clínica. Se recomienda emplear cuestionarios más descriptivos para mejorar la utilidad del examen clínico.

Evaluación de la disfunción vaginal en mujeres embarazadas sintomáticas y asintomáticas mediante la utilización de los estados vaginales básicos (EVB) y su comparación con el estudio microbiológico convencional / Evaluation of vaginal dysfunction in symptomatic and asymptomatic pregnant women by using the analysis of basic vaginal states (BVS) and its comparison with the conventional microbiological study

Durante el embarazo se producen frecuentemente infecciones del tracto genital inferior asociadas a complicaciones maternas y perinatológicas. El objetivo del trabajo fue evaluar la disfunción vaginal mediante el análisis de los estados vaginales básicos (EVB) por la metodología del balance del contenido vaginal (BACOVA) y compararlo con el estudio microbiológico convencional en el diagnóstico de candidiasis, tricomonosis y vaginosis bacteriana (VB). Entre 2010 y 2012 se estudiaron 1238 pacientes embarazadas; 1046 eran asintomáticas (A) y 192 sintomáticas (S). La prevalencia del EVB I fue del 59,5 % y 26 %, respectivamente. El EVB II se observó en 19,7 % de las mujeres A y en 17,2 % de las S. El EVB III se detectó solamente en las A, en 0,4 %. El EVB IV se observó en 14,4 % de las A y en 38 % de las S. El EVB V se detectó en 6 % de las A y en 18,8 % de las S. En las mujeres A, las levaduras se asociaron a los EVB I y II en el 55,5 % y 23,2 % de los casos, respectivamente; entre las S, alcanzaron el 32,4 % y 31 % de los casos, en igual orden. Las tricomonas se asociaron al EVB I en el 50 % de las A, al EVB IV en el 44,4 % de las S y al EVB V en el 33,3 % de las S. La sensibilidad del BACOVA para detectar levaduras fue 80,4 % en las A y 85,5 % en las S; para detectar tricomonas, del 40 % y 75 %, y para detectar VB, del 100 % en los dos grupos. La especificidad del BACOVA fue 100 % para todos los patógenos en las A y en las S. El estudio de los EVB resultó útil para orientar el diagnóstico a la disfunción vaginal, independientemente de la sintomatología, por lo que se sugiere este estudio como parte del control prenatal.

Infections of the lower genital tract associated to maternal and perinatal complications frequently occur during pregnancy. The aim of this study was to evaluate vaginal dysfunction through the analysis of basic vaginal states (BVS) using the methodology of balance of the vaginal content (BAVACO) and to compare it with the microbiological study of candidiasis, trichomoniasis and bacterial vaginosis (BV). Pregnant patients (1238) were examined from 2010 to 2012. In asymptomatic (A) (n: 1046) and symptomatic pregnant women (S) (n: 192) BVS I was 59.5% and 26% of the patients, respectively. BVS II was observed in 19.7% of A and in 17.2% of S. BVS III was only detected in A in 0.4%. BVS IV was observed in 14.4% of A and in 38% of S. BVS V was detected in 6% of A and in 18.8% of S. Yeasts were associated to BVS I and II in 55.5% and 23.2% of A, respectively; and in 32.4% and 31% of S, respectively. Trichomonas were associated to BVS I in 50% of A, to IV in 44.4% of S and to V in 33.3% of S. BAVACO susceptibility to detect yeasts was 80.4% and 85.5% in A and S, respectively; 40% and 75% in A and S, respectively, to detect trichomonas and 100% in A and S to detect BV. BAVACO specificity was 100% for all pathogens in A and S. The study of BVS proved useful as a guide to evaluate vaginal dysfunction, regardless of symptomatology. Therefore, this study is recommended as prenatal control. Infections of the lower genital tract associated to maternal and perinatal complications frequently occur during pregnancy.

Prevalence of bacterial vaginosis in Grenadian women of reproductive age / Prevalencia de la vaginosis bacteriana en mujeres granadinas en edad reproductiva

OBJECTIVES: To determine the prevalence of bacterial vaginosis (BV) among Grenadian women of reproductive age using the routinely collected Pap smear data for the period January 2009 to December 2011. METHODS: A retrospective review of a cross-section of Pap smears was obtained for women between the ages of 15 and 49 years, using the national centralized data bank at the General Hospital in St George's, Grenada. Women aged younger or older than the sample group, as well as those who were reported as being menopausal or hysterectomized were excluded from the study. Demographic and laboratory data were collected and descriptive statistics reported. RESULTS: The prevalence of BV was 19.5% for the three-year period among the 2677females included in the analysis with the 20-29-year age group having the largest percentage of infection (43.6%). An increase in the trend of prevalence between 2009 (16.1%) and 2011 (21.4%) was also observed. Candida vaginalis and Trichomonas vaginalis were present in 3.6% and 0.85%, respectively. Additionally, atypical cells of unknown significance and cervical dysplasia were documented in 5.3% and 1.8% of the smears, respectively. CONCLUSION: Practicing physicians in Grenada need to consider increased screening for BV in women who may present with non-specific symptoms. Further research is necessary to determine the predisposing factors in Grenadian women and associations with the disease and to assist in the development of national education programmes to alter behavioural practices that could result in the acquisition and persistence of BV among women of reproductive age in Grenada.

OBJETIVOS: Determinar la prevalencia de vaginosis bacteriana (VB) entre mujeres granadinas de edad reproductiva utilizando datos de pruebas de Papanicolaou rutinariamente recolectados durante el período de enero de 2009 a diciembre de 2011. MÉTODOS: Se realizó una revisión retrospectiva de una muestra representativa de Papanicolau de mujeres entre las edades de 15 a 49 años, usando el Banco Nacional de Datos centralizados en el Hospital General de Saint George, Granada. Las mujeres de edad más jóvenes o mayores que el grupo de muestra, así como aquellas que se registraron como menopáusicas o histerectomizadas fueron excluidas del estudio. Datos demográficos y del laboratorio fueron recogidos, y se reportó la estadística descriptiva. RESULTADOS: La prevalencia de BV fue de 19,5% para el período de tres años entre las 2677 hembras incluyeron en el análisis, presentando el grupo de edad de 20-29 años el mayor porcentaje de infección (43,6%). También se observó un aumento en la tendencia de la prevalencia entre 2009 (16,1%) y 2011 (21,4%). Candida vaginalis y Trichomonas vaginalis estuvieron presentes en 3,6% y 0,85%, respectivamente. Además, se documentaron las células anormales de significación desconocida y displasia cervical en 5,3% y 1,8% de los frotis, respectivamente. CONCLUSIÓN: Los médicos en ejercicio en Granada necesitan considerar el aumento del tamizaje para la detección de BV en mujeres que puedan presentarse con síntomas no específicos. Se necesita continuar las investigaciones a fin de determinar los factores de predisposición en las mujeres Granadinas y las asociaciones con la enfermedad. Asimismo, es necesario ayudar al desarrollo de programas nacionales de educación encaminados a modificar aquellas conductas que podrían conducir a la adquisición y la persistencia delaBV entre las mujeres de edad reproductiva en Granada.

Gardnerella vaginalis-associated bacterial vaginosis in Bulgarian women

ABSTRACT BACKGROUND: Bacterial vaginosis (BV) is the most common cause of vaginal discharge in women of reproductive age. The purpose of this study was to determine the frequency of BV in Bulgarian pregnant and nonpregnant women from several age ranges and to compare three different laboratory methods for Gardnerella vaginalis detection in patents suffering from BV. METHODS: Between September 2011 and June 2012, 809 women of 16-40 years of age separated in two major groups: nonpregnant - 469 (355 with and 114 without symptoms) and pregnant - 340 (213 and 127 respectively) were enrolled for the study. The women underwent three different laboratory tests simultaneously: scoring of Gram staining of vaginal smear, culture, and polymerase chain reaction (PCR) assay for G. vaginalis. RESULTS: The microscopic method detected high frequency of BV in symptomatic (57%) whereas only a minority of asymptomatic subjects (14%) were detected. G. vaginalisassociated BV was diagnosed in approximately equal proportions when evaluated with PCR and microscopic method for both pregnant and nonpregnant women. The comparative analysis of microscopic evaluation, culture and PCR assays demonstrated greater concurrence (about 90%) between Gram staining and PCR detection for BV, than both methods compared to culture. The combination of microscopy and PCR turned out to be very reliable and repeatable for detecting G. vaginalis-associated BV. CONCLUSIONS: This is the first comparative investigation on the epidemiology of G. vaginalisassociated BV in Bulgaria. The established highest frequency in the young Bulgarian women (21-30 years) is alarming and should be considered in prophylaxis and reproductive programmes.

Posible papel de Bacteroides fragilis enterotoxigénico en la etiología de la vaginitis infecciosa / Possible role of enterotoxigenic Bacteroides fragilis in the etiology of infectious vaginitis

La vaginitis es un trastorno ginecológico frecuente producido por distintas causas, algunas de las cuales permanecen desconocidas. Bacteroides fragilis es el anaerobio más importante en bacteriología clínica. Algunas cepas son enterotoxigénicas y se asocian con síndromes intestinales y extraintestinales. Recientemente han sido aisladas de pacientes con vaginitis. En este trabajo se planteó investigar la posible asociación de B. fragilis enterotoxigénico con la vaginitis infecciosa. Fueron procesadas 265 muestras de exudado vaginal. 202 de mujeres sintomáticas y 63 mujeres sanas. La identificación de los microorganismos se realizó por métodos convencionales. En 31,2% de las pacientes sintomáticas se identificaron: Gardnerella vaginalis, Candida albicans, Mobiluncus, Mycoplasma hominis, Ureaplasma urealyticum y Streptococcus agalactiae. En 27 pacientes sintomáticas y en 5 mujeres sanas se identificó B. fragilis. Estas cepas fueron cultivadas en medio líquido e incubadas durante 48 h a 36° C en anaerobiosis. La toxicidad en los sobrenadantes se ensayó en células HT-29. 18 cepas de B. fragilis aisladas de pacientes sintomáticas fueron enterotoxigénicas, ya que indujeron alteraciones en la monocapa celular y en las células. No se identificó en mujeres sanas (P<0,05). 77,7% de las cepas de B. fragilis enterotoxigénicas no se encontraron asociadas con otros patógenos específicos. Este hecho sugiere que pudiera ser un agente causante de vaginitis, ya que el efecto de la enterotoxina sobre la E-cadherina del epitelio vaginal podría facilitar la invasión y su posible papel patógeno en la vagina. Esta es la primera investigación que asocia a Bacteroides fragilis enterotoxigénico como posible causa de vaginitis infecciosa.

Vaginitis is a common gynecologic disorder. It is due to several causes, some even unknown. Bacteroides fragilis is the most important anaerobe in clinical bacteriology, some strains of this group are notable for being enterotoxigenic and they have been associated with intestinal and extraintestinal syndromes. They have recently been isolated from patients with vaginitis. The purpose of this study was to investigate a possible association of enterotoxigenic B. fragilis with infectious vaginitis. 265 samples of vaginal exudate were processed, 202 from symptomatic patients and 63 healthy women. The identification of the microorganisms was carried out by conventional methods. In 31.2% of symptomatic patients were identified: Gardnerella vaginalis, Mobiluncus, Candida albicans, Mycoplasma hominis, Ureaplasma urealyticum and Streptococcus agalactiae. B. fragilis was identified in 27 symptomatic patients and 5 healthy women. These strains were cultivated in liquid medium and incubated during 48 h at 36°C in anaerobe chambers. Supernatant activity was assayed in HT-29 cells. Eighteen B. fragilis strains isolated from symptomatic patients were enterotoxigenic, because induced alterations in target cell morphology. It was not identified in healthy women (P<0.05). 77.7% of enterotoxigenic B. fragilis strains were not associated with other specific pathogens. This fact suggests that enterotoxigenic B. fragilis could be a cause for vaginitis. The effect of enterotoxin on E-cadherin of vaginal epithelium could facilitate invasion and its possible pathogenic role in the vagina. This is the first report that associates enterotoxigenic Bacteroides fragilis as a possible cause of infectious vaginitis.

Micro-biota of vaginal infection among women in the reproductive age group: a hospital-based study

To study the prevalence of micro-organisms causing vaginal infection in women of child bearing age attending the Obstetrics and Gynecology Outpatient Department. This study was done with 479 patients in the age group of 15-45 years attending the Obstetrics and Gynecology OPD of Gulf Medical College Hospital, Ajman with various gynecological complains between January 2010 to December 2011. Sociodemographic details along with their reproductive history were recorded from the medical records. Vaginal swabs were taken from the patients irrespective of their marital status and sent for smear examination and culture identification. The presence of concomitant diseases in these patients was also recorded. Out of 479 patients studied, 50% were Asians followed by Middle East and African patients [47%] and Caucasians [3%]. Ninety percent of the patients were in the age group of 20-40 years. Eighty three percent were married and had children and the rest did not have any children. The majority of the women complained of vaginal discharge [83%], pruritus vulvae [45%], dysuria [18%], abdominal pain [16%] and vulvo vaginitis [5%]. Microbiology reports revealed normal flora in 29% of the specimens collected. The most common organism found was Candida species [51%] among the specimens. Bacterial infection was found in 36% cases, of which Gram negative cocci [Gonococci] were more prevalent than Gram positive cocci [Staphylococcus and Streptococcus species; 18%]. The incidence of Gram negative bacilli was 7% and that of the flagellates belonging to Trichomonas species was 13.5%. Diabetes mellitus and hypertension were present in 9.4% and 3.3% patients respectively which did not show any correlation with the microbial flora. The vaginal infection was identified in 71% women in their reproductive age with or without disease symptoms. It is recommended that all women should get a periodic checkdone for any asymptomatic infection

Importancia del estudio del balance del contenido vaginal (BACOVA) en el control preventivo de las trabajadoras sexuales / Importance of studying the balance of vaginal content (BAVACO) in the preventive control of sex workers

El objetivo de este trabajo fue estudiar a un grupo de 229 trabajadoras sexuales de Comodoro Rivadavia (Chubut), atendidas en centros públicos de salud de dicha ciudad, mediante la aplicación del método conocido como balance del contenido vaginal (BACOVA). Este método comprende el estudio morfológico de la microbiota vaginal, como así también de la reacción infamatoria. Incluye el análisis del contenido vaginal en fresco y por tinciones de Gram y de Giemsa, de modo de integrar la exploración de todo el panorama biológico. El 35,37 % de estas mujeres presentó microbiota normal (MN); el 15,72 %, microbiota intermedia (MI); el 23,14 %, vaginosis bacteriana (VB) y el 10,48 %, vaginitis microbiana inespecífca (VMI). Los casos de vaginitis por levaduras y por Trichomonas vaginalis comprendieron el 8,30 % y 6,99 % de las mujeres, respectivamente. Se observó el desplazamiento de la MN hacia una MI, que se correspondió con el predominio de bacterias corineformes. Por otra parte, no se reconoció un marcado desequilibrio del contenido vaginal ante la colonización e infección por levaduras o por T. vaginalis: el 48 % de los casos de estas vaginitis convencionales no presentaron reacción infamatoria vaginal (RIV). El 24,89 % de los casos de MN presentaron una signifcativa RIV, y en más del 50 % de las mujeres se diagnosticaron disfunciones vaginales en ausencia de sintomatología. Estos resultados se podrían asociar a un incremento del riesgo gineco-obstétrico, lo que afecta la salud sexual y reproductiva de la población estudiada.

The aim of this work was to study the vaginal microenvironment in sex workers from Comodoro Rivadavia, Chubut. For that purpose, BAVACO procedures were applied. A total of 229 female sex workers attended public health centers. Vaginal secretions were analyzed by Gram and Giemsa stains. The following results were obtained: normal microbiota 35.37 %, intermediate microbiota 15.72 %, bacterial vaginosis 23.14 %, microbial nonspecifc vaginitis, Donders'"aerobic vaginitis" 10.48 %, yeast vulvovaginitis 8.30 %, and trichomoniasis 6.99 %. The intermediate microbiota was characterized by a decrease in the number of lactobacilli and the presence of diphtheroid bacilli cell types. The population studied shared increased values of vaginal dysfunctions. These results are considered risk factors for obstetric and gynecologic diseases.

Prevalencia de vaginosis bacteriana en trabajadoras sexuales chilenas / Prevalence of bacterial vaginosis in Chilean sex workers

OBJETIVO: Determinar la prevalencia de vaginosis bacteriana (VB) en trabajadoras sexuales chilenas y relacionar los hallazgos con variables sociodemográficas, sexuales y clínicas. MÉTODO: Se estudió una muestra de 379 trabajadoras sexuales que asistían para control a Unidades de Atención y Control de Salud Sexual de Chile. A todas se las entrevistó para obtener antecedentes sociodemográficos y sexuales, se les realizó evaluación clínica que incluyó características del flujo vaginal, pH y prueba de aminas, y se les tomó una muestra vaginal para tinción de Gram. Para el diagnóstico de VB se empleó el criterio de Nugent. Los datos fueron analizados con EPI-INFO 3.4.1 y BioStat, utilizándose un grado de significación de P < 0,005. RESULTADOS: La prevalencia de VB fue de 69,1 por ciento. El síndrome no se asoció a las variables sociodemográficas edad y escolaridad. Las mujeres que vivían (casadas o no) con su pareja tuvieron menos frecuencia de VB en comparación con las mujeres solteras (P < 0,001). No hubo variables sexuales asociadas a VB, en tanto que el empleo del dispositivo intrauterino (DIU) sí lo estuvo (P < 0,0001). La presencia de descarga vaginal, pH vaginal alterado y prueba de aminas positiva se asociaron a la infección (P < 0,0001). CONCLUSIONES: En coincidencia con otros estudios realizados distintos países, el presente trabajo observó que las trabajadoras sexuales chilenas tienen una alta prevalencia de VB, con mayor riesgo para aquellas que usan DIU como método de anticoncepción o que no conviven (casadas o no) con su pareja.

OBJECTIVE: To determine the prevalence of bacterial vaginosis (BV) in Chilean sex workers and relate the findings to sociodemographic, sexual, and clinical variables. METHODS: A sample of 379 sex workers seen in Chilean Sexual Health Monitoring and Care Units for check-ups was studied. All of them were interviewed to obtain their sociodemographic and sexual history. A clinical examination was performed that included the characteristics of vaginal discharge, pH, and amine test. A vaginal sample was taken for Gram stain. The Nugent criteria were used for the diagnosis of BV. The data was analyzed with EPI-INFO 3.4.1 and BioStat, using a degree of significance of P < 0.005. RESULTS: BV prevalence was 69.1 percent. The syndrome was not associated with the sociodemographic variables, age or education. BV was less common in women (married or unmarried) who lived with their partners than in single women (P < 0.001). There were no sexual variables associated with BV, whereas use of intrauterine devices was related (P < 0.0001). The presence of vaginal discharge, abnormal vaginal pH, and positive amine test were associated with infection (P < 0.0001). CONCLUSIONS: Like other studies conducted in different countries, this study observed that Chilean sex workers have a high prevalence of BV, with greater risk for women who use IUDs for birth control or women (married or unmarried) who do not live with their partners.

Biotypes and virulence factors of Gardnerella vaginalis isolated from cases of bacterial vaginosis.

The present study was conducted to correlate the biotypes of Gardnerella vaginalis strains isolated from cases of bacterial vaginosis and their virulence factors. Thirty-two strains of G. vaginalis isolated from cases of bacterial vaginosis were biotyped. Adherence to vaginal epithelial cells, biofilm production, surface hydrophobicity, phospholipase C and protease activity were tested on these isolates. Biotype 1 was the most prevalent (8; 25%), followed by biotype 2 (7; 21.9%) and biotypes 5 and 8 (5; 15.6%). We did not find any statistical correlation between G. vaginalis biotypes and its virulence factors. Virulence factors expressed by G. vaginalis were not associated with a single biotype.

Comparación de los criterios de Nugent y Spiegel para el diagnóstico de vaginosis bacteriana y análisis de los resultados discordantes por el método de Ison y Hay / Nugent and Spiegel criteria for the diagnosis of bacterial vaginosis. Analysis of discordant specimens by the Ison and Hay method

Background: Vaginal infection is the commonest cause of genital symptoms and has obstetric and gynecological implications. Aim: To compare the Nugent and Spiegel methods for the diagnosis of bacterial vaginosis (BV) and to analyze discordant specimens using Ison and Hay (Ison/Hay) criteria. Material and Methods: After discardingcases with Candidiasis, deficientspecimens or those lacking bacteria, a total of348 Gram-stained smears vaginal specimens receivedfor the diagnosis of BV, were analyzed. Results: Vaginal microbiota was classified as normal in 203 and 237 samples (58 and 68 percent of samples), accordingto Nugent and Spiegel criteria, respectively One hundred andfive (30 percent) and 111 samples (32 percent), were classified as VB accordingto Nugent and Spiegel criteria, respectively. Both criteria were concordant in 308 samples (88.5 percent). The 40 (11.5 percent) discordant specimens were classified as intermedíate microflora by the Nugent system and as normal or BV by Spiegel. Among these, the Ison/Hay procedure identified four categories of microbiota. Ten (25 percent) specimens were classified as grade II microbiota, confirming their categorization by Nugent as intermedíate microbiota, six (15 percent) were classified in the III category, confirming the diagnosis ofBV by Spiegel, 13 (32.5 percent) corresponded to the category III, that does not exist in the Nugent and Spiegel categorization systems. Finally, 11 specimens could not be assigned to one category due to microscopic limitations to distinguish bacterial morphotypes. Conclusions: The systems proposed by Spiegel, Nugent and Ison I Hay are comparable for the diagnosis of BV. However, we recommend the use of Ison/ Hay procedure to evalúate vaginal microbiota, due to its wider range of categories, allowing a better discrimination ofthe vaginal microbiota.

Bacterial vaginosis: clinical, epidemiologic and microbiological features / Bacterial vaginosis: clinical, epidemiologic and microbiological features

Bacterial Vaginosis (BV) is a polymicrobial clinical syndrome, whose etiology has not been fully understood. It occurs in approximately 30% of the women in childbearing age and is the result of the shift of protective resident microorganisms as Lactobacillus spp. by opportunistic pathogenic bacteria such as Gardnerella vaginalis. Patients with BV generally present copious, thin, homogeneous, milky, foul-smelling flow. Vaginal pH is > 4.5 and microscopy reveals bacteria-covered epithelial cells, termed “clue cells”. Around 50% of the patients are asymptomatic and the disease is associated with gynecologic complications, such as cervicitis, salpingitis, endometritis, post-operative infections and pelvic inflammatory disease; and obstetric complications, such as premature rupture of the membranes, preterm deliveries, chorioamniotitis and postpartum endometritis. Although the Nugent´s method is accepted as the “gold standard” for diagnosing BV, Amsel criteria are generally used for diagnosis in clinical practice. The Papanicolaou method is a valid diagnostic option, chiefly when it yields a positive result (mean specificity 95% when compared to gold standard). G. vaginalis has been almost universally recovered from women with BV, plays an important role in the pathogenesis of the disease, besides it may be detected in about 50% of healthy women. According to the literature, first-line drugs for BV treatment worldwide are metronidazole and clindamycin. However, regional studies on G. vaginalis drug susceptibility patterns are needed faced the so fast growing antimicrobial resistance phenomenon.

Identification and in vitro production of Lactobacillus antagonists from women with or without bacterial vaginosis

Lactobacilli isolated from the vaginal tract of women with and without bacterial vaginosis (BV) were identified and characterized for the production of antagonists. Bacterial samples were isolated from healthy women (N = 16), from patients with clinical complaints but without BV (N = 30), and from patients with BV (N = 32). Identification was performed using amplified ribosomal DNA restriction analysis. Production of antagonistic compounds was evaluated by the double-layer diffusion technique using Gram-positive (N = 9) and Gram-negative bacteria (N = 6) as well as yeast (N = 5) as indicator strains. Of a total of 147 isolates, 133 were identified as pertaining to the genus Lactobacillus. Lactobacillus crispatus was the species most frequently recovered, followed by L. johnsonii and L. jensenii. Statistical analysis showed that L. crispatus was more frequent in individuals without BV (P < 0.05). A higher production of antagonists was noted in L. crispatus isolates from healthy women (P < 0.05). More acidic local pH and higher H2O2 production by isolated lactobacilli from healthy women suggest these mechanisms as the possible cause of this antagonism. In conclusion, a significant correlation was detected between the presence and antagonistic properties of certain species of Lactobacillus and the clinical status of the patients.

Utility of pH test & Whiff test in syndromic approach of abnormal vaginal discharge.

Background & objective: In India, National AIDS Control Organization (NACO) introduced syndromic approach to treat patients with abnormal vaginal discharge without a need for laboratory tests. Simple tools like pH test and Whiff test can be done without high expertise, microscope and even speculum. This can improve diagnostic value of syndromic approach of abnormal vaginal discharge. The present study was conducted to evaluate sensitivity and specificity of pH test and Whiff test in diagnosis of abnormal vaginal discharge, considering microscopic diagnosis as gold standard. Methods: This prospective hospital-based study included 564 women with abnormal vaginal discharge. All women were subjected to gynaecological examination, pH test and Whiff test. The findings were compared with microscopic examination. Statistical analysis was done by calculating proportions, percentage, sensitivity and specificity. Results: Vaginitis was diagnosed in 301 (53.37%) women. Bacterial vaginosis (BV) was the commonest type of vaginitis (39.01%). Cervical erosion was the second most common cause (17.91%) and physiological discharge was the third (14.36%). pH > 4.5 and positive Whiff test had sensitivity of 94.09 per cent and specificity 87.5 per cent in diagnosing BV. Similarly pH < 4.5 and positive or negative Whiff test had sensitivity of 83.72 per cent in diagnosing candidiasis. Interpretation &conclusion: pH test and Whiff test can improve diagnostic value of speculum examination where microscope facilities are not available.

Only one third of the exams showed the presence of Lactobacillus (89 women - 32.1 percent). Fungal growth occurred in the cultures of 14 participants (5.1 percent). In most cases, culture revealed the presence of Corynebacterium (94.2 percent), Gram-positive cocci (98.2 percent), as well as Gram-positive ...

Vaginosis citolítica: un diagnóstico diferencial poco frecuente de vulvovaginitis micótica a repetición / Cytolytic vaginosis: a rare differential diagnosis of fungal recurrent vulvovaginitis

Los síntomas compatibles con vaginitis y vaginosis, son la causa más frecuente de consulta al ginecólogo. La descarga vaginal abundante y el prurito, constituyen la primera sospecha de estas patologías. Sin embargo, debemos tener presente que el aumento significativo de lactobacilos, conocido como lactobacilosis, puede expresarse también con los mismos síntomas y signos de una vulvovaginitis micótica. Si esta condición se mantiene en el tiempo, puede provocar un grado de acidez anormal en la vagina, y puede llevar a una lisis de las células epiteliales que se conoce como vaginosis citolítica. Este diagnóstico, aunque es poco frecuente, debemos sospecharlo especialmente, en aquellas mujeres que relatan tener múltiples consultas por candidiasis vaginal, con escasa o nula respuesta frente a la terapia antimicótica.

The symptoms consistent with vaginitis and vaginosis are the most common cause of the visit to the gynecologist. Heavy vaginal discharge and pruritus are the first suspicion of this pathology. However, the significant increase in lactobacilli, known as lactobacilosis can be expressed also with the same symptoms and signs of a fungal vulvovaginitis. If this condition is maintained overtime, can cause abnormal acidity in the vagina, and may lead to epithelial cell lysis, which is known as cytolytic vaginosis. This diagnosis, although rare, should be suspected especially in women who reported having multiple consultations for vaginal candidiasis, with little or no response to antifungal therapy.

[Diagnostic value of Pap smear test in screening of bacterial vaginosis]

Bacterial vaginosis alters normal vaginal flora and leads to gynecologic complications. Early diagnosis of bacterial vaginosis is so important, because of being asymptomatic of about fifty percent of patients. This study was conducted to study the diagnostic value of the Papanicolaou smear in the screening of bacterial vaginosis compared with vaginal Gram stain as a standard method. This analytic cross- sectional study was conducted on 150 consecutive patients referred to a gynecologic clinic. Each patient had a standard Papanicolaou smear and Gram stain of vaginal discharge. Detection of clue cell in Pap smear, and fulfill of Nugent criteria in Gram stain of vaginal discharge was diagnosed as bacterial vaginosis. Sensitivity, specificity, positive predictive value, and negative predictive value of the Papanicolaou smear were calculated compared with the results of Gram stain as the standard method for diagnosis of bacterial vaginosis. In our study, Pap smear had sensitivity of 69.23%, specificity of 99.24%, positive predictive value of 94.73% and negative predictive value of 94.28% in the diagnosis of bacterial vaginosis. This study showed that vaginal Pap smear is a valid and reliable method in detecting bacterial vaginosis

Spectrum of Lactobacillus species present in healthy vagina of Indian women.

Background & objectives: Lactobacilli are depleted in vagina of women suffering from recurring episodes of bacterial vaginosis with vaginal pH >5. With the objective of making available probiotic lactobacilli for replenishment in such women, a study was undertaken to isolate and characterize the Lactobacilli present in women with eco-healthy vagina in Delhi. No information is so far available on the species of Lactobacilli resident in vagina of women in India. Methods: Vaginal swabs were taken from 80 women with informed consent after ethical approval and grown in MRS broth. Gram-positive, catalase-negative bacilli generating about 200 bp amplicon by PCR with Lactobacillus genus specifi c primers were further characterized by employing species specifi c primers followed by sequencing of 16S rDNA. Isolates of the same species were differentiated by random amplifi ed polymorphic DNA (RAPD) profi les. Results: The predominant species isolated were L. reuteri present in 26 (32.5%) women, L. fermentum in 20 (25%), and L. salivarius in 13 (16.25%) women. Sequencing of 16S rDNA of 20 isolates showed that except for two isolates of L. plantarum, sequences of the remaining agreed well with PCR identifi cation. None of the isolates had similar RAPD profi le. Interpretation & conclusions: Our fi ndings showed lactobacilli species present in healthy vagina of women in India differ from those reported from other countries. This information would be useful to development of probiotic tablets seeking to replenish the missing lactobacilli for reproductive health of women in India.
