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.

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.

Estrategia de atención al síndrome de flujo vaginal en gestantes. Sancti Spíritus / Strategy care in pregnant vaginal discharge syndrome. Sancti Spíritus

Fundamento: las infecciones de trasmisión sexual constituyen un problema de salud en todo el mundo, sin embargo en la provincia se carece de información sobre bases científicas de los resultados de la aplicación de la estrategia para la atención del síndrome de flujo vaginal en la Atención Primaria de Salud. Objetivo: describir los resultados de la aplicación de la estrategia para la atención del síndrome de flujo vaginal a partir de la información aportada por especialistas de 16 consultorios médicos de familia en tres municipios espirituanos. Metodología: se realizó investigación descriptiva, transversal que incluyó los 16 especialistas de Medicina General Integral de igual número de consultorios tipo 1 de municipios priorizados para las infecciones de trasmisión sexual, a quienes se le aplicó una encuesta, los resultados se presentaron en tablas utilizando frecuencias absolutas y relativas. Resultados: más de la mitad de las gestantes atendidas padecían el síndrome de flujo vaginal y a todas le estudiaron sus parejas sexuales, los médicos conocen la existencia del flujograma; en Sancti Spíritus y Fomento los facultativos dominan mejor el contenido del stock de medicamentos para su tratamiento; carecen de información sobre la entrega gratuita del módulo de medicamentos destinado a esta problemática y la totalidad conoce la conducta a seguir ante una gestante con flujo vaginal. Conclusiones: la estrategia para el manejo del síndrome de flujo vaginal en gestantes no es aplicada adecuadamente en los municipios estudiados, por el desconocimiento de la disponibilidad de medicamentos eficaces y gratuitos en el área de salud para el tratamiento de la gestante y su pareja.

Background: sexually transmitted infections are a health problem worldwide, but in the province there is a lack of information on scientific basis of the results of the implementation of the strategy for the care of vaginal discharge syndrome in Primary Health Care. Objective: to describe the results of the implementation of the strategy for the care of vaginal discharge from the information provided by specialists from 16 family doctor offices in three municipalities of Sancti Spíritus. Methodology: descriptive, cross investigation was used that included 16 specialists in Comprehensive General Medicine with equal number of Type 1 doctor offices of prioritized municipalities for sexually transmitted infections, to whom a survey was applied, the results were presented in tables using absolute and relative frequencies. Results: more than half of the cared pregnant women suffered vaginal discharge syndrome and their sexual partners were studied as well, doctors are aware of the flowchart; physicians dominate the content of the stock of medicines for treatment better in Sancti Spiritus and Fomento; they are lack of information about the free drug delivery module devoted to this condition and all of them know the medical procedures to follow in the presence of a woman with vaginal discharge. Conclusions: the strategy for the management of vaginal discharge syndrome in pregnant women is not properly implemented in the municipalities studied, due to the lack of availability of effective and free drugs in the healthcare area for the treatment of pregnant women and their partners.

Relação entre vaginose bacterianae prematuridade / Relationship between bacterial vaginosis and prematurity

A prematuridade tem um grande impacto no resultado neonatal, sendo responsável por um alto índice de morbimortalidade neonatal e agregando vários fatores em sua etiologia; dentre estes, a infecção geniturinária ocupa um papel de destaque e a vaginose bacteriana é sua principal representante. Após levantamento dos mais recentes estudos acerca da relação entre a prematuridade e a vaginose bacteriana, constou uma discrepância nos resultados, principalmente quanto à recomendação de seu rastreamento em gestantes de baixo risco para prematuridade, sendo que alguns autores recomendam e outros contraindicam sua realização. Características metodológicas podem justificar a falta de unanimidade na literatura especialmente quanto à idade gestacional ideal para o rastreamento, sendo que os melhores resultados obtidos com rastreamento precoce, entre 16 e 20 semanas de gestação. Quanto à droga de escolha para o tratamento, muitos utilizam o metronidazol, porém esta droga é ineficaz na redução da prematuridade e, por isso, alguns autores recomendam a clindamicina e os macrolídeos. Devido à importância do impacto da prematuridade na morbimortalidade neonatal, permanece a recomendação de que mais estudos sejam realizados

Prematurity has a major impact on neonatal outcome, accounting for a high rate of morbidity and mortality. Several factors are involved in the etiology of prematurity. Among these factors, genitourinary infection plays a key role. One of the main causes of genitourinary infections is bacterial vaginosis. A survey of recent studies about the relationship between bacterial vaginosis and prematurity was carried out. Results were conflicting, mainly with regard to screening low-risk pregnant women for prematurity. Some authors advise screening whereas others contraindicate it. Differences in methodological approach may account for the lack of consensus in literature, particularly concerning the ideal gestational age for tracking. The best results were achieved with early screening, between 16 and 20 weeks of gestation. Regarding drug of choice, many professionals opt for metronidazole, although this drug is ineffective in the reduction of prematurity, which explains the choice of some authors for clindamycin and macrolides. Due to the major impact of prematurity on neonatal mortality, more studies should be carried out

Relación entre enfermedad periodontal, infección bacteriana ascendente y patología placentaria con parto prematuro / Relationship between periodontal diseases and ascending bacterial infection with preterm delivery

Background: There is an association between periodontal diseases and preterm delivery. Aim: To assess the relationship between periodontal diseases, ascending bacterial infection and placental pathology with preterm delivery. Patients and methods: A periodontal examination and collection of amniotic fluid and subgingival plaque samples were performed in women with preterm labor with intact membranes, without an evident clinical cause or preterm premature rupture of membranes, without clinical chorioamnionitis or labor and a gestational age between 24 and 34 weeks. Microbial invasion of the amniotic cavity was defined as the presence of a positive amniotic fluid culture. Cervicovaginal infection was defined as a bacterial vaginosis or positive culture of cervix or vagina with a high neutrophil count. Ascending bacterial infection was diagnosed as the microbial invasion of the amniotic cavity by ascending bacteria or cervicovaginal infection. Corioamnionitis, funisitis or vellositis were diagnosed. Results: Fifty-nine women were included: fortytwowith preterm labor with intact membranes and seventeen with preterm premature rupture of membranes. The prevalence of periodontal diseases was 93.2%. Microbial invasion of the amniotic fluid was detected in 27.1% of patients. Periodontal pathogenic bacteria were isolated in 18.6% of amniotic fluid samples and 71.2% of subgingival plaque samples. The prevalence of ascending bacterial infection was 83.1% and in 72.9% of women it was associated with periodontal disease. Preterm delivery (<37 weeks) occurred in 64.4% of patients and was significantly associated with generalized periodontal disease and with the association of ascending bacterial infection and periodontal diseases. Patients with preterm delivery and generalized periodontal disease had a higher frequency of chorioamnionitis and funisitis...

Co-infection of herpes simplex virus (HSV) with human immunodeficiency virus (HIV) in women with reproductive tract infections (RTI).

In India, HSV seroprevalence and its coinfection with HIV among female patients with reproductive tract infections (RTI) are sparse. We aim to ascertain the seroprevalence of HSV and its coinfection with HIV and common sexually transmitted infections attending Obstetrics and Gynaecology outpatient department, RIMS. The study included 92 female patients with RTI. Diagnostic serology was done for HSV-1 and HSV-2 using group specific IgM indirect immunoassay using ELISA, HIV by 3 ELISA/Rapid/Simple (E/R/S) test of different biological antigen. Diagnosis of RTI was made on clinical grounds with appropriate laboratory investigations--microscopy, Gram stain smear etc. Bacterial vaginosis was diagnosed using Nugent's criteria, Syphilis by rapid plasma reagin (RPR) card test and Chlamydia trachomatis by IgG ELISA. Out of 92 sera tested for HSV, 18 (19.6%) were IgM HSV positive and 9 (9.8%) were HIV positive. Co-infection rate of HSV in HIV positive was 16.7%. None of the patients had clinical herpes genitalis, all were subclinical cases. 55.5% of HSV positives belongs to age group 21 to 30 years. Of the HSV-1 and HSV-2 IgM positives 3 (15%) had HIV, 4 (22.2%) bacterial vaginosis, 2 (11.1%) were RPR positive, 4 (22.2%) Chlamydia trachomatis, 3 (15%) were pregnant. 16 (88.8%) were unemployed, 14 (77.7%) had education level below 10 standard. Our study suggest that every case of RTI, be it an ulcerative or nonulcerative must be thoroughly evaluated by laboratory testing for primary subclinical genital HSV coinfection as this has profound implications on their judicious management and aversion of complications. Early diagnosis and treatment of HSV infection together with prophylaxis for recurrent HSV disease will prevent progression and spread of HIV disease.

Periodontitis as a Risk Factor for Preterm Low Birth Weight

PURPOSE: There is growing evidence showing that a number of complex human diseases are caused or are at least influenced by periodontal diseases. Such diseases include cardiovascular diseases, respiratory diseases, diabetes mellitus and osteoporosis. The aim of study was to evaluate periodontal diseases as a risk factor for a preterm low birth weight. MATERIALS AND METHODS: A total of 48 mothers, 20 of who had a preterm low birth weight delivery, were examined in the Clinics of Periodontology, Faculty of Dentistry, Cumhuriyet University. The periodontal exams consisted of a full mouth pocket depth, a Loe and Sillness Gingival index score measurements, and a panoramic radiograph analysis. Information on any other factors that may cause a preterm low birth weight was obtained from the family physician. RESULTS: The study results indicated that periodontitis (OR: 3.6 95% CI: 1.06-12.18) together with bacterial vaginosis (OR: 11.57 95% CI: 1.26-105.7) were independent risk factors of a preterm low birth weight. According to the data obtained from this study, the paternal age, tobacco use and the mothers' height were not significant risk factors for a preterm low birth weight. CONCLUSION: Within the limits of this study, it is concluded that a poor periodontal health status of the mother may be a potential risk factor for a preterm low birth weight.

Associação entre trabalho de parto prematuro e vaginose bacteriana: uma revisão da literatura / Association between premature birth and bacterial vaginosis: a review of the literature

Balance del contenido vaginal en el diagnóstico diferencial de vaginosis-vaginitis: Reacción inflamatoria vaginal en embarazadas sintomáticas / Balance of vaginal content in vaginosis-vaginitis differential diagnosis: Vaginal inflammatory reaction in symptomatic pregnant women

El objetivo del trabajo fue validar el alto valor predictivo de BACOVA (Balance del contenido vaginal, disponible en www.fba.org.ar/proeco) en el diagnóstico microscópico diferencial de vaginosis bacteriana (VB) y vaginitis microbiana inespecífica (VMI). Fueron estudiadas 299 embarazadas sintomáticas. Se determinó por microscopía el Valor Numérico (Nugent) (VN), células guía (CG), morfotipos extraños (Mex), leucocitos por campo (Lpc), tricomonas (TV) y levaduras (LE) con lectura a 400X. Los resultados globales fueron: VN de 7 a 10, 16,4% del total de casos. BACOVA permitió diferenciar 11,7% de los casos con VN de 7 a 10, con reacción inflamatoria vaginal (RIV) menor de 10 Lpc, como casos típicos de BV. Con igual VN se detectó 4,7% de casos con RIV con más de 10 Lpc, compatibles con VMI. En sólo 7,3% de los casos de LE detectadas por microscopía (20,4% en total), se confirmó una RIV significativa. Hubo 2,7% del total de casos con RIV significativa, pH<4,5 y resultado negativo para el resto de los criterios estudiados. La determinación de la RIV, fue imprescindible, junto al VN, en el diagnóstico diferencial de VB y VMI. La RIV también es necesaria para establecer la significación clínica de la presencia de levaduras. BACOVA detecta casos con RIV significativa (2,7%), como único marcador, con pH inferior a 4,5, compatibles con infección del tracto genital superior.

This study was undertaken to demonstrate the high diagnostic predictive value of BACOVA (Balance of Vaginal Content, www.fba.org.ar/proeco) for bacterial vaginosis and microbial non specific vaginitis, in pregnant women primary health care. BACOVA including Nugent score (Gram 1000X) and leucocyte count (Wet mount and Giemsa, using 400X) was evaluated in 299 symptomatic pregnant women. Nugent score 7 to 10 was detected in 16.4%. Crossing Nugent value 7 to 10 with leucocytes counts shows that only 11.7% were below 10 leucocytes per field and 4.7% had a significant vaginal inflammatory response. Yeasts were detected in 20.4% but only in 7.2% of cases they show a significant association with vaginal inflammatory response. In 2.7% of the cases there was a significant vaginal inflammatory response, with pH below 4.5, VN from 0 to 3 and negative for TV, fishy odor, and exogenous microbial morphotypes. Simultaneous study of vaginal inflammatory response and Nugent score is mandatory in order to detect true cases of bacterial vaginosis (11.7%) from those of potential microbial non specific vaginitis (4.7%) (Donders' "aerobic vaginitis") Besides, vaginal inflammatory response became a strong criterion to define yeast vulvovaginitis (7.2%). Cases (2.7%) with score 0 to 3, negative for other criteria, with a high vaginal inflammatory response, are predictors of upper genital infections.

Prevalence of bacterial vaginosis in Thai pregnant women with preterm labor in Siriraj hospital.

OBJECTIVE: To study the prevalence of bacterial vaginosis (BV) in pregnant women with preterm labor in Siriraj hospital. MATERIAL AND METHOD: A cross-sectional study of 158 pregnant women with suspected preterm labor was performed between January and July 2005. The subjects enrolled in the present study were between 28+0 and 36+6 menstrual weeks. BV blue test was performed on the vaginal fluid collected from lower one- third of vagina. RESULTS: The prevalence of BV in women in the preterm labor group was 25.8% compared to 14.1% in the preterm contraction group (p = 0.07). CONCLUSION: Compared with preterm contractions a higher prevalence of BV was found in the pregnant women with preterm labor. Given that a quarter of pregnant women with preterm labor tested positive for BV, it might be appropriate to perform this test in the triage setting.

The clinical and microbiological correlates of premature rupture of membranes.

Prematurity is the cause of 85% of neonatal morbidity and mortality. Premature rupture of the membranes (PROM) is associated with 30-40% of preterm deliveries. A case-control study conducted between July 2002 and 2003 examined the correlates and risk factors for PROM in Mysore, India. WBCs in vaginal fluid, leucocytes in urine, UTI and infection with E. coli, S. aureus, C. albicans and BV were significantly associated with PROM. BV, E. coli and WBCs in vaginal fluid were independent risk factors. Screening and treatment of BV and E. coli infection in pregnancy may reduce the risk of PROM.

Impact of treatment for bacterial vaginosis on prematurity among brazilian pregnant women: a retrospective cohort study

CONTEXTO E OBJETIVO: A vaginose bacteriana vem sendo apontada como fator de risco para prematuridade e outras complicações perinatais. Entretanto, a eficácia do seu tratamento na prevenção destas complicações ainda não está esclarecida. O objetivo deste estudo foi avaliar o impacto do tratamento da vaginose bacteriana durante o pré-natal de baixo risco para a prevenção de prematuridade e outras complicações perinatais. TIPO DE ESTUDO E LOCAL: Coorte retrospectivo observacional, no Departamento de Tocoginecologia, Universidade Estadual de Campinas (Unicamp). MÉTODOS: Foram estudadas 785 gestantes de baixo risco com resultado da bacterioscopia de secreção vaginal. Foram identificados três grupos de mulheres: 580 sem vaginose bacteriana durante a gestação, 134 com vaginose bacteriana tratada com imidazólicos (metronidazol, tinidazol, ou secnidazol) durante a gestação, e 71 com vaginose bacteriana não tratada durante a gestação. O diagnóstico de vaginose bacteriana foi realizado utilizando os critérios de Nugent na bacterioscopia vaginal da primeira consulta. RESULTADOS: O parto prematuro ocorreu em 5,5% do grupo de mulheres sem vaginose bacteriana, 22,5% do grupo com vaginose bacteriana não tratada, e 3,7% do grupo com vaginose bacteriana tratada. A razão de risco para as complicações perinatais no grupo com vaginose bacteriana não tratada durante a gestação foi: 7,5 (intervalo de confiança, IC, de 95%: 1,9-34,9) para rotura prematura de membranas no pré-termo, 3,4 (IC de 95%: 1,4-8,1) para trabalho de parto prematuro, 6,0 (IC de 95%: 1,9-19,7) para parto prematuro e 4,2 (IC de 95%: 1,2-14,3) para baixo peso ao nascer. CONCLUSÃO: O tratamento da vaginose bacteriana reduziu significativamente os índices de prematuridade e outras complicações perinatais entre as gestantes de baixo risco, independentemente da história prévia de parto prematuro.

Vulvovaginites: estudo das variaçoes de pH vaginal e microflora associada / Vulvovaginitis: vaginal pH changes and associated microflora

PURPOSE: To establish a correlation between pH vaginal and the microflora associated in carriers of vulvovaginites. METHODS: In the present study, the cytopathological examination and the vaginal flow in a group of 65 sexually active women had been carried through, 20 and 72 years, taken care of in the Laboratório de Citologia Clínica do Departamento de Análises Clínicas e Toxicológicas da Universidade Federal do Rio Grande do Norte, for determination of microorganisms in cervicovaginal sample and of pH in the vaginal flow. RESULTS: Associating pH vaginal with the presence of vulvovaginitis, it was evidenced that the Candida sp. occurred more frequently in pH 4.0, Trichomonas vaginalis in pH 6.0, Gardnerella vaginalis in pH 5.0, coconuts in pH 5.0, bacilli in pH 4.0 and cocos/bacilos in pH 6.0. It was observed that all the patients had presented at least one type of ethiological agent of vulvovaginiti and an associated microflora. CONCLUSION: The joint accomplishment of the cytological examinations and the determination of pH revealed important for directing the microflora associated with the vulvovaginiti, suggesting, of this form, that pH vaginal plays preponderant role how much to the presence of the infectious agents in the vaginal ecosystem.

Frequency and diagnosis of bacterial vaginosis

To determine the frequency of bacterial vaginosis [BV] in women with vaginal discharge, and to compare different diagnostic tests for its diagnosis. Cross-sectional study. The Aga Khan University Hospital from June 1998 to May 2000. All women attending the Obstetrics and Gynecology clinics at The Aga Khan University Hospital, with the complaints of vaginal discharge, were examined with the help of a speculum. The vaginal pH was measured, samples for bacterial cultures were obtained. A slide was prepared for the gram's stain and Whiff-test was also performed. BV was diagnosed, when the vaginal discharge fulfilled at least three of the composite clinical criteria [Amsel's criteria], a st and ard method for the diagnosis of bacterial vaginosis: homogenous [pasty] discharge, pH more than 4.5, positive Whiff-test and the presence of clue cells. The frequency of BV was observed to be 16.1%. The culture for Gardnerella vaginalis was compared with the composite clinical criteria. The sensitivity, specificity, positive and negative predictive values of the culture, calculated for the diagnosis of BV were 93.8%, 70%, 37.7% and 98% respectively. The use of laboratory tests in conjunction with clinical findings is necessary for diagnosis of BV. The composite clinical criteria for the diagnosis of BV are rapid, reliable and inexpensive method

Association of bacterial vaginosis with preterm delivery

Preterm delivery is the leading cause of infant morbidity and mortality. Preterm labor and premature rupture of membranes and low birth weight have been associated with either specific maternal genital tract infections or an altered microflora in pregnancy. Bacterial vaginosis is one of the implicating factors for preterm labor and preterm delivery. Objective of the study is to study the frequency of Bacterial vaginosis in preterm labor. By identifying and observing the frequency of Bacterial vaginosis as a causative factor in preterm labor, we can reduce its frequency by taking certain measures and indirectly we would be able to overcome the problem of infant mortality and morbidity due to prematurity. Observational study. Fifty patients.Obstetric and Gynecology department unit II of Abbasi Shaheed Hospital and Karachi Medical and Dental College Karachi, From Jan 2003 to Jan 2004. Patients included were presented with established labor after 24[th] weeks and before 37[th] weeks of gestations. Patients with singleton pregnancy were with or without rupture of membranes. Patients excluded were multiple pregnancies, current pregnancy with sepsis, cervical incompetence, and antepartum bleeding. Patients presented with chorioamnionitis, diabetes, mellitus, hypertension, cardiac disease, renal disease and urinary tract infection were also excluded. Patients presented with effective uterine contractions after 24[th] weeks and before 37[th] weeks of gestation were admitted. Full history and examination were recorded on a given proforma. Full base line investigations, including complete blood picture, random blood sugar, and urine detailed report, blood group and Rh factor were done. High vaginal swab was taken and sent for culture/sensitivity and microscopy for clue cells. Vaginal pH was determined by using Nitrazine paper and change in color of Nitrazine paper was recorded. Whiff test was performed by taking some secretion by disposable syringe on glass slide and fishy odor was observed after adding a drop of KOH on slide. Amsel's criteria were applied to all cases preterm labor and results was analyzed on SPSS 10. Results were based on Amsel's criteria. Fifty patients were enrolled in this study. Out of fifty patients only 2[4%] patients fulfilled all four criteria, while 29[58%] patients fulfilled three criteria, 4[8%] patients fulfilled 2 criteria and 15[13%] patients fulfilled 1 criterion. Hence Bacterial vaginosis was found in 35[70%] patients. Bacterial vaginosis was associated with majority of patients presented with preterm labor and responsible for perinatal morbidity and morbidity

Bacterial vaginosis and vaginal anaerobes in preterm labour.

Maternal genital infections, particularly bacterial vaginosis has been implicated as a cause for preterm labour and adverse pregnancy outcomes. This prospective study aimed to study the association of bacterial vaginosis with preterm labour. The prevalence of bacterial vaginosis was studied in 60 women in preterm labour who had no recognisable cause for prematurity and in 60 term labour controls. Demographic factors, pregnancy outcome and reproductive history were also studied. Vaginal specimens for Gram-stain and culture were collected from posterior vaginal fomix and bacterial vaginosis was defined by evaluation of Gram-stained smear by Spiegel criteria. Bacterial vaginosis was diagnosed in 31.6% of women in preterm labour and in 15% of term labour controls ( p<0.05). In preterm labour group, preterm delivery occurred in 48 women (80%) out of which 18 women had bacterial vaginosis and term delivery occurred in only one woman with the condition. Anaerobes were significantly associated with bacterial vaginosis ( p<0.01) and were more common in women with preterm labour ( b>0.05). The results indicates that bacterial vaginosis has a significant association with preterm labour and adverse pregnancy outcome.

Prevalence of bacterial vaginosis in antenatal women.

Bacterial vaginosis is an established risk factor in pregnant women for premature rupture of membranes and preterm delivery. This study was carried out to find out the prevalence of Bacterial Vaginosis (BV) in antenatal women with vaginal discharge and the effect of treatment with Metronidazole gel on pregnancy outcome. One hundred and fifty symptomatic and fifty asymptomatic women in second trimester of pregnancy in the age group of 20-30 years were included in the study. Gram stained smears of vaginal discharge were examined for evidence of BV with a scoring system by Nugent et al and was found to be positive in 38.5% in symptomatic antenatal women. Intravaginal metronidazole gel application was found to be an effective therapeutic option. Incidence of preterm labour was more in untreated cases.

Incidence of Gardnerella vaginalis, Candida sp and human papilloma virus in cytological smears

CONTEXT: In spite of the wide-ranging literature on the microbiology of normal and abnormal flora of the vagina, there are few studies on the relationship between human papilloma virus (HPV) and other vaginal microorganisms. OBJECTIVE: To analyze the frequency of infection by human papilloma virus (HPV) and other agents like Candida sp., Gardnerella vaginalis and Trichomonas vaginalis in cytological smears. DESIGN STUDY: Retrospective study SETTING: A public tertiary referral center. SAMPLE: An analysis of 17,391 cytologies from outpatients seen between January 1997 and August 1998. The control group was made up of patients in the same age group and same period with no cytological evidence of HPV infection. Patients with a diagnosis of cervical intraepithelial neoplasia (CIN) II or III were excluded from this analysis. MAIN MEASUREMENTS: The diagnosis of HPV infection was made in accordance with the criteria of Schneider et al. and the diagnosis of Gardnerella vaginalis was made with a finding of clue cells. RESULTS: 390 (2.24 per cent) had alterations consistent with infection by HPV, sometimes associated with CIN I. The results showed that Gardnerella vaginalis was the most frequent agent in women with HPV infection (23.6 per cent versus 17.4 per cent; P <0.05), while in the control group the most frequent agent was Candida sp. (23.9 per cent versus 13.8 per cent; p <0.001). CONCLUSION: In spite of this study being based solely on cytological criteria, in which specific HPV and Gardnerella diagnostic tests were not used, the cytological smear is widely used in clinical practice and the data presented in this investigation show that there is an association between Gardnerella vaginalis and HPV infection. It remains to be established whether the microorganisms favor each other
