Asociación entre la exposición a violencia íntima de pareja contra la mujer y el reporte de secreción y úlceras genitales

Objetivo: Evaluar la asociación entre la violencia íntima de pareja emocional, física y sexual con el auto reporte de secreción y úlcera genital en mujeres participantes de una encuesta poblacional. Métodos: Se realizó un análisis de la Encuesta Demográfica y de Salud Familiar del Perú, 2021. Los criterios de inclusión fueron tener 15 a 49 años, ser casadas o convivientes, y estar seleccionadas y entrevistadas para el módulo de violencia doméstica. Se estimó la prevalencia de auto reporte de secreción y úlcera genital. La asociación con la violencia íntima de pareja fue realizada mediante regresión logística binaria con la estimación de la razón de momios, considerando el diseño muestral complejo. Resultados: La prevalencia del reporte de úlcera o secreción genital fue 10,0%. La razón de momios para reportar secreción o úlcera genital entre las mujeres que sufrieron violencia física leve comparado con las no expuestas fue 2,25 (IC95%: 1,72 a 2,94), el riesgo incrementó a 3,42 (IC95%; 2,39 a 4,90) entre las mujeres que sufrieron violencia física severa. La razón de momios generada por la exposición a violencia sexual para reportar secreción o úlcera fue mayor (OR: 3,84, IC95%: 2,47 a 5,96). Conclusiones: Las mujeres expuestas a cada uno de los tres tipos de violencia íntima de pareja tuvieron mayor chance de reportar secreción o úlcera genital en los últimos 12 meses. El riesgo se incrementa cuando coexisten la forma física y sexual.

Objective: To assess the association between emotional, physical, and sexual intimate partner violence with self-reported discharge and genital ulcer in women from participants in a population-based survey. Methods: An analysis of the Demographic and Family Health Survey of Peru, 2021 was performed. Inclusion criteria were 15-49 years of age, married or cohabiting, and selected and interviewed for the domestic violence module. The prevalence of self-reported discharge and genital ulcer was estimated. The association with intimate partner violence was performed by binary logistic regression with odds ratio estimation, considering the complex sample design. Results: The prevalence of reporting genital ulcer or discharge was 10.0%. The odds ratio for reporting genital discharge or ulcer among women who suffered mild physical violence compared with those not exposed was 2.25 (95%CI: 1.72-2.94), the risk increased to 3.42 (95%CI: 2.39-4.90) among women who suffered severe physical violence. The odds ratio generated by exposure to sexual violence for reporting discharge or ulcer was higher (odds ratio: 3.84, 95% CI: 2.47-5.96). Conclusions: Women exposed to each of the three types of intimate partner violence had a higher chance of reporting genital discharge or ulcer in the last 12 months. The risk increases when physical and sexual violence coexist.

Caracterización clínico-epidemiológica de la mujer infértil / Epidemiological-clinical characterization of infertile women

RESUMEN Fundamento: la infertilidad es la incapacidad para tener hijos, pero con posibilidad de embarazo que no llega a término. En el mundo existen 187 millones de parejas afectadas. Objetivo: caracterizar las mujeres atendidas en la consulta municipal de infertilidad. Métodos: se realizó un estudio descriptivo observacional y retrospectivo en Policlínico Docente Emilio Daudin Bueno, de la provincia Guantánamo, durante el periodo enero de 2017 a junio de 2020. El universo estuvo constituido por las 128 mujeres infértiles de 19-39 años atendidas en consulta. Fueron evaluadas variables cualitativas y cuantitativas.

Resultados: predominaron las féminas de 25-29 años con infertilidad secundaria; las infecciones genitales como factor causal predominante, seguido de los antecedentes obstétricos desfavorables y en la mayoría de las pacientes el peso saludable como evaluación nutricional. Se pudo percibir que del total de las pacientes, en algunas existió algún grado de aumento del peso corporal. Conclusiones: la consulta de infertilidad cumple el objetivo de lograr la concepción de las féminas según las causas que impiden la misma, la actuación de cada profesional de la salud al incorporar los conocimientos necesarios a emplear en su adecuado seguimiento, permitirá concretarlo desde la Atención Primaria de Salud.

ABSTRACT Background: infertility is the inability to have children, but with the possibility of pregnancy, which does not reach term. There are one hundred and eighty-seven million affected couples in the world. Objective: to characterize women treated in the municipal consultation of infertility. Methods: an observational and retrospective descriptive study was carried out in Emilio Daudinot Bueno Docent Polyclinic, Guantánamo, during the period January 2017 to June 2020. The universe was made up of 128 infertile women who met the inclusion criteria: 19-39 years old, seen in infertility consultation and fulfill the concept of infertility. Qualitative and quantitative variables were evaluated. The primary data was obtained from the medical records of the patients seen. Results: females aged 25-29 years with secondary infertility predominated; genital infections as the predominant cause factor, followed by unfavorable obstetric history and, in most patients, healthy weight as a nutritional assessment. It was possible to perceive that of the total number of patients, in some there was some degree of increase in body weight. Conclusions: the infertility consultation fulfills the objective of achieving the conception of women by attenuating the causes that prevent it, the performance of each health professional by incorporating the necessary knowledge to be used in its adequate follow-up, will allow specifying it from Primary Care of health.

Actualización de la infección por Chlamydia trachomatis en mujeres / Update of Chlamydia trachomatis infection in women

La infección por Chlamydia trachomatis es la infección de transmisión sexual bacteriana más frecuente en el mundo. En este artículo se revisa la prevalencia reportada en Chile, cuadro clínico, diagnóstico, tratamiento, prevención y complicaciones a largo plazo en mujeres.

Chlamydia trachomatis infection is known to be the most common sexually transmitted bacterial infection world-wide. This article reviews the prevalence reported in the Chilean population, as well as the clinical manifestations, diagnosis, treatment, prevention and complications in women

Association of spontaneous abortion and Ureaplasma parvum detected in placental tissue.

Spontaneous abortion is considered a public health problem having several causes, including infections. Among the infectious agents, bacteria of the vaginal microbiota and Ureaplasma parvum have been associated with abortion, but their participation needs to be further elucidated. This study aims to evaluate the influence of Mollicutes on the development of spontaneous abortion. Women who underwent spontaneous abortion and those with normal birth (control) were studied. Samples of cervical mucus (CM) and placental tissue were collected to identify Mollicutes using the quantitative polymerase chain reaction methodology. Eighty-nine women who had a miscarriage and 20 women with normal pregnancies were studied. The presence of Mollicutes in placental tissue increased the chance of developing miscarriage sevenfold. The prevalence of U. parvum in women who experienced spontaneous abortion was 66.3% in placental tissue. A positive association was observed between the detection of U. parvum in samples of placental tissue and abortion. There was a significant increase in microbial load in placental tissue for M. hominis, U. urealyticum and U. parvum compared to the control group. Detection of U. parvum in CM in pregnant women can ascend to the region of the placental tissue and trigger a spontaneous abortion.

Papiloma virus humano en adolescentes y jóvenes menores de 25 años / Human papillomavirus in adolescents and people younger than 25

RESUMEN Fundamento: la infección genital causada por el virus del papiloma humano es una infección de transmisión sexual común, que afecta a millones de personas de todo el mundo. Objetivo: determinar el comportamiento del papiloma virus humano de localización genital en adolescentes y jóvenes femeninas menores de 25 años. Métodos: se realizó un estudio descriptivo transversal en menores de 25 años atendidas en la consulta de patología de cuello del Policlínico de Nuevitas en el período comprendido desde enero a diciembre de 2016; con un universo de 93 pacientes con diagnóstico confirmado de papiloma virus humano en la citología orgánica. Resultados: el mayor número de las pacientes con papiloma virus humano presentaron lesiones intraepiteliales, con predominio de alto grado. Más de la mitad de las lesiones correspondieron al grupo de jóvenes entre 20 y 24 años. Se observó relación de la presencia del virus con varios factores de riesgos, casi la totalidad tuvieron su primeras relaciones sexuales precozmente. Alrededor de la tercera parte tuvieron relaciones sexuales múltiples, prevalecieron entre tres y cinco parejas sexuales, fue relevante la ectopia cervical, como antecedentes ginecológicos se observó la leucorrea como síntoma más frecuente. Conclusiones: existe una estrecha relación entre adolescentes con riesgos y presencia del papiloma virus humano, la presencia de este virus es un factor predisponente para que se presenten lesiones intraepiteliales cervicales.

ABSTRACT Background: genital infection caused by human papillomavirus is a common sexually transmitted infection, which affects millions of people around the world. Objective: to determine the behavior of human papillomavirus of genital location in adolescents and young women under 25 years. Methods: a cross-sectional descriptive study was carried out in girls under 25 years of age attended in the neck pathology clinic of the Nuevitas Polyclinic in the period from January to December 2016; with a universe of 93 patients that with confirmed diagnosis of human papillomavirus in organic cytology. Results: the greatest number of patients with human papillomavirus presented intraepithelial lesions, with a high degree of predominance. More than half of the injuries corresponded to the group of young people between 20 and 24 years old. Relationship of the presence of the virus with several risk factors was observed, almost all had their first sexual intercourse early. Around the third part of them had multiple sexual relations, three to five sexual partners prevailed, cervical ectopia was relevant, as gynecological history, leukorrhea was observed as the most frequent symptom. Conclusions: there is a close relationship between adolescents with risks and presence of human papillomavirus, the presence of this virus is a predisposing factor for cervical intraepithelial lesions.

Prevalence of ureaplasma urealyticum, mycoplasma hominis and human papillomavirus coinfection in people attending a sexually transmitted infections (STI)/HIV reference centre in Salvador, Bahia, Brazil / Prevalência da coinfecção por ureaplasma urealyticum, mycoplasma hominis e papilomavírus humano em pessoas atendidas em centro de referência de doenças sexualmente transmissíveis (DST)/HIV em Salvador, Bahia

Introduction: Ureaplasma urealyticum and Mycoplasma hominis are frequently found at many women's and men's urogenital tract, and have been associated with non-gonococcal urethritis, cervicitis, infertility, chorioaminionitis and adverse pregnancy outcomes. Some studies show high prevalence of human papillomavirus (HPV) in patients with non-gonococcal urethritis, while also presenting high frequency of Ureaplasma urealyticum infection in women with cervicalcytology abnormalities and men with genital warts. Objectives: To evaluate the prevalence of Ureaplasma urealyticum, Mycoplasma hominis and HPV coinfection in people attending a sexually transmitted infections (STI)/HIV reference centre and to identify the risk factors associated. Methods: A cross-sectional study with patients aged >18 years, carried out for Ureaplasma urealyticum and Mycoplasma hominis from July 1st to December 31, 2015, in a STI/HIV reference centre from the State of Bahia, Brazil. Sociodemographic and clinical data were obtained from secondary data from patients' charts and laboratory findings, and analyzed using SPSS 20.0. Pearson's χ2 test or Fisher's exact test was used to evaluate categorical variables. HPV clinical diagnosis was considered positive as the presence of genital warts. Results: In this study, 849 patients were included ­ 196 men and 653 women. Of the sample, 51.4% was diagnosed with at least one of the two bacteria. The prevalence of Mycoplasma hominis infection was higher in coinfection (16.7%) than in isolated infection (2.2%). The prevalence of Ureaplasma urealyticum isolated infection was 32.4%. A strong association was found between the presence of genital warts and Ureaplasma urealyticum infection, with an estimated risk of 1.230 (p=0.014). Conclusion: Our findings suggest the need for further investigation for Ureaplasma urealyticum infection in patients presenting genital warts on physical examination. In addition, in this context, greater attention should be given to women and pregnant women.

Introdução: Ureaplasma urealyticum e Mycoplasma hominis são frequentemente encontrados no trato urogenital de homens e mulheres, e têm sido associados à ocorrência de uretrites não gonocócicas, cervicites, infertilidade, corioamnionite e outras patologias obstétricas. Alguns estudos mostraram alta prevalência de papilomavírus humano (HPV) em pacientes com uretrites não gonocócicas, bem como alta frequência de infecção por Ureaplasma urealyticum em mulheres com anormalidades na citologia cervical e homens apresentando verruga genital. Objetivos: Avaliar a prevalência da coinfecção por Ureaplasma urealyticum, Mycoplasma hominis e HPV em pessoas atendidas em um centro de referência de DST/HIV e identificar os fatores de risco associados. Métodos: Estudo transversal com pacientes maiores de 18 anos, testados para Ureaplasma urealyticum e Mycoplasma hominis entre 1º de julho e 31 de dezembro de 2015, em um centro de referência de DST/HIV da Bahia, Brasil. Os dados clínicos e sociodemográficos foram obtidos por coleta de dados secundários a partir dos prontuários e achados laboratoriais dos pacientes e analisados usando SPSS 20.0. O teste de χ2 Pearson ou teste exato de Fisher foram usados para avaliar as variáveis categóricas. O diagnóstico clínico do HPV foi considerado positivo quando houve presença de verruga genital. Resultados: Foram incluídos neste estudo, 849 pacientes, sendo 196 homens e 653 mulheres. Da amostra, 51,4% foi diagnosticada com infecção por pelo menos uma das duas bactérias. A prevalência de infecção por Mycoplasma hominis foi maior na coinfecção (16,7%) do que isoladamente (2,2%). A prevalência da infecção isolada por Ureaplasma urealyticum foi de 32,4%. Houve forte associação entre a presença de verruga genital e infecção por Ureaplasma urealyticum, com estimativa de risco de 1,230 (p=0,014). Conclusão: Nossos achados sugerem a necessidade de investigação adicional para a infecção por Ureaplasma urealyticum nos pacientes apresentando verruga genital ao exame físico. Além disso, nesse contexto, maior atenção deve ser dada a mulheres e gestantes.

Chlamydia trachomatis infection in young pregnant women in Southern Brazil: a cross-sectional study / Infecção por Chlamydia trachomatis em gestantes jovens no Sul do Brasil: um estudo transversal / Infección por Chlamydia trachomatis en gestantes jóvenes en el sur de Brasil: un estudio transversal

Abstract: This study estimated the prevalence of Chlamydia trachomatis infection during pregnancy in a sample of women up to 29 years of age in the city of Pelotas, Rio Grande do Sul State, Brazil, and investigated socio-demographic risk factors such as maternal age, marital status, maternal schooling, and family income. C. trachomatis infection was diagnosed with PCR using BD ProbeTecTM CT/GC Amplified DNA Assay. Socio-demographic, behavioral, and reproductive data were collected using structured questionnaires. All collections were performed by previously trained medical students. The study included a stratified probabilistic sample from four maternity hospitals in the city. The sample included 562 pregnant women, and prevalence of C. trachomatis infection was 12.3% (95%CI: 9.6-15.0). No significant association was identified between C. trachomatis infection and any of the target variables, including obstetric outcomes such as history of preterm delivery. Our findings in terms of low treatment adherence, only 43% of the women and 9.7% of partners, associated with high C. trachomatis prevalence, reinforce the need to implement routine screening for C. trachomatis during prenatal care. The attempt to diagnose and treat this infection after delivery, as in this study, limits the possibility of success.

Resumo: Este estudo estimou a prevalência de Chlamydia trachomatis durante a gestação entre mulheres de até 29 anos e investigou fatores de risco sociodemográficos, como idade materna, estado civil, escolaridade materna e renda familiar, para a infecção na cidade de Pelotas, Rio Grande do Sul, Brasil. Infecção por C. trachomatis foi diagnosticada por PCR utilizando BD ProbeTecTM CT/GC Amplified DNA Assay system. Dados sociodemográficos, comportamentais e reprodutivos foram coletados através de questionários estruturados. Todas as coletas foram realizadas por estudantes de medicina treinados. Amostra probabilística estratificada de quatro maternidades da cidade foi estudada. A amostra constou de 562 gestantes e a prevalência de infecção por C. trachomatis foi de 12,3% (IC95%: 9,6-15,0). Não foi identificada associação significativa entre infecção por C. trachomatis e as variáveis investigadas, incluindo desfechos obstétricos como parto pretermo. Nossos achados de baixa adesão ao tratamento, de apenas 43% entre as mulheres e de 9,7% entre os parceiros, associados a alta prevalência, reforçam a necessidade de implementar rastreamento de rotina para C. trachomatis durante a assistência pré-natal. A tentativa de diagnosticar e tratar esta infecção depois do parto, como feito neste estudo, limita a possibilidade de sucesso.

Resumen: Este estudio estimó la prevalencia de Chlamydia trachomatis durante la gestación, entre mujeres de hasta 29 años, e investigó factores de riesgo sociodemográficos como: edad materna, estado civil, escolaridad materna y renta familiar, para esta infección en la ciudad de Pelotas, Rio Grande do Sul, Brasil. La infección por C. trachomatis fue diagnosticada mediante PCR, utilizando BD ProbeTecTM CT/GC Amplified DNA Assay system. Los datos sociodemográficos, comportamentales y reproductivos se recogieron a través de cuestionarios estructurados. Todas las recogidas de datos se realizaron por parte de estudiantes de medicina entrenados. Se estudió la muestra probabilística estratificada de cuatro maternidades de la ciudad. La muestra constó de 562 gestantes y la prevalencia de infección por C. trachomatis fue de un 12,3% (IC95%: 9,6-15,0). No se identificó una asociación significativa entre infección por C. trachomatis y las variables investigadas, incluyendo desenlaces obstétricos como el parto pretérmino. Nuestros hallazgos de baja adhesión al tratamiento, solamente un 43% entre las mujeres y un 9,7% entre los compañeros, asociados a la alta prevalencia, refuerzan la necesidad de implementar una exploración de rutina para C. trachomatis durante la asistencia prenatal. La tentativa de diagnosticar y tratar esta infección después del parto, como se realizó en este estudio, limita la posibilidad de éxito.

O risco de infecções genitais em mulheres usuárias de dispositivo intrauterino / The risk of genital infections in women using intrauterine device

Dispositivos intra-uterinos (DIU) são amplamente usados como método contraceptivo e têm uma possível associação com infecções do trato genital inferior. Objetivo: Avaliar se o uso de DIU está associado com infecções do trato genital e por quais patógenos. Métodos: Revisão sistemática de estudos dos bancos de dados PubMed, Highwire-Stanford e Google Scholar usando as seguintes palavras-chave: "cytology IUD" OR "IUD AND cytology" OR "cytology" OR "cytological techniques" OR "cytological AND techniques" OR "cell biology" OR "cell AND biology". Resultados: Foram encontrados inicialmente 2817 artigos e selecionados 16, que obedeciam os critérios de inclusão. Com base nestes estudos, o microorganismo associado ao uso de DIU e principal causa de doença inflamatória pélvica é o Actinomyces spp. Há risco 14 vezes maior de presença do Actinomyces spp. em usuárias de DIU em relação a não usuárias. No entanto, parece haver uma maior depuração aparente de infecção por Papilomavírus humano (HPV) entre usuárias de DIU de cobre. Conclusão: Há uma associação entre o uso de DIU e algumas infecções genitais, tal como vaginose bacteriana; no entanto, o agente mais evidentemente associado é o Actinomyces spp. Há uma possível maior depuração de infecção por HPV entre usuárias de DIU de cobre.

Intrauterine devices (IUDs) are widely used contraceptive methods that have a possible association with lower genital tract infections. Objective: To assess whether IUD is associated with genital tract infection and which pathogens cause it. Methods: Systematic review of studies in PubMed database, Highwire-Stanford, and Google Scholar using the following keywords: "cytology IUD," OR "IUD AND cytology" OR "cytology" OR "cytological techniques," OR "cytological AND techniques," OR "cell biology," OR "cell" and "biology". Results: Sixteen out of the 2,817 initial articles were selected using the inclusion criteria. On the basis of these studies, the microorganisms that can colonize the IUD, the main acute pelvic inflammatory disease occasioner is Actinomyces spp. There is a risk 14 times greater of the presence of Actinomyces spp. in IUD users than in non-users. However, there would be a higher apparent depuration of human papillomavirus (HPV) infection among copper T users. Conclusion: There is an association between the use of IUD and some genital infections such as bacterial vaginosis; however, more evidently associated with Actinomyces spp. There is a possible higher depuration of infection by HPV among copper T users.

Prevalence of Trichomonas vaginalis and Candida albicans among Brazilian Women of Reproductive Age.

INTRODUCTION: There are no studies assessing the simultaneous occurrence of Candida albicans (C. albicans) and Trichomonas vaginalis (T. vaginalis) in the primary health care in Brazil. Despite different conditions to establishment of each one, the co-detection of both has been reported by some authors in previous studies from other regions. AIM: To compare the prevalence of T. vaginalis and C. albicans in correlation with associated variables. MATERIALS AND METHODS: A cross-sectional study conducted in a family health clinic in the Federal District of Brazil, between November 2014 and March 2015. Vaginal swabs were collected from 201 women of the reproductive age selected from women registered at the family health clinic. Minors and pregnant women were excluded. The rates of T. vaginalis and Candida albicans prevalence were evaluated with vaginal pH, the whiff test, sexual practices and other social and demographic variables. Difference between proportions was assessed by Z-Test. RESULTS: C. albicans was present in 20% of the women, while 16% of them had T. vaginalis. The simultaneous occurrence of the agents was found in 1.5%. Significant differences were found between prevalence rates for the variables race/skin colour, practice of anilingus and lifetime number of sexual partners. CONCLUSION: The prevalence of T. vaginalis exceeds C.albicans among women with higher numbers of sexual partners. The prevalence of C. albicans was higher than T. vaginalis among white women and those who practice active and receptive anilingus. The simultaneous occurrence of the two microorganisms was uncommon.

Guía de práctica clínica para el manejo sindrómico de los pacientes con infecciones de transmisión sexual y otras infecciones del tracto genital - 2013 / Clinical practice guideline for syndromic management of patients with sexually transmitted infections and other genital tract infections - 2013

Objetivo: reducir la variabilidad de la práctica en el manejo de las infecciones del tracto genital y de las infecciones de transmisión sexual; apoyar a los profesionales de la salud que atienden pacientes con ITG/ITS, con la más reciente evidencia respecto a la efectividad y seguridad de las intervenciones para la prevención primaria, secundaria y terciaria, y generar indicadores de implementación de la guía y de su impacto en la salud pública.Materiales y métodos: se constituyó un equipo desarrollador en el que participaron diferentes profesionales de la salud y representantes de pacientes. Se formularon preguntas clínicas relevantes y se realizó una búsqueda en repositorios nacionales e internacionales de Guías. Se evaluaron las Guías disponibles en cuanto a su calidad y aplicabilidad. Dado que ninguna guía cumplió con los criterios de adaptación, se decidió el desarrollo de una Guía de Novo. Se realizó una búsqueda de revisiones sistemáticas y metaanálisis, ensayos clínicos y estudios observacionales en las bases de datos pubmed, ovid, embase, cochrane y lilacs. Se elaboraron las tablas de evidencia y las recomendaciones con la aproximación grade por metodología de consenso formal e informal.Resultados: se presenta la “Guía de práctica clínica” con las recomendaciones y la evidencia de soporte para la prevención, el diagnóstico, tratamiento en cuanto a efectividad y seguridad, y seguimiento de los síndromes de: cervicitis, uretritis, úlcera genital, flujo vaginal, inflamación escrotal y bubón inguinal. Conclusiones: como recomendación central de implementación se plantea el manejo del paciente por medio de la dosis única y tratamiento expedito del compañero cuando sea posible. La Guía deberá actualizarse en tres años.

Objective: To reduce practice variability in the management of genital tract infections and sexually transmitted infections, and provide healthcare practitioners that care for patients with GTIs/STDs with the most recent evidence on the effectiveness and safety of the interventions for primary, secondary and tertiary prevention; and to create indicators to track the implementation of the guideline and its impact on public health. Materials and methods: A development team was set up with the participation of different healthcare professionals and patient representatives. Relevant clinical questions were asked and a search was conducted in the national and international guideline repositories. The existing guidelines were evaluated for quality and applicability. Considering that none of the guidelines met the criteria for adoption, it was decided to develop a de novo guideline. A search of systematic reviews and meta-analysis, clinical trials and observational studies was conducted in the pubmed, ovid, embase, cochrane and lilacs databases. Evidence tables and recommendations were prepared using the grade approach on the basis of the informal and formal consensus methodology. Results: The “Clinical Practice Guideline” is presented, including the recommendations and support evidence for prevention, diagnosis and treatment in terms of effectiveness and safety, and follow-up of cervicitis, urethritis, genital ulcer, vaginal discharge, scrotal inflammation and inguinal bubo. Conclusions: The core recommendation for implementation is patient management using a single dose and expedite treatment of the partner whenever possible. The Guideline must be updated in three years.

Infecção genital e marcadores preditivos do parto prematuro / Genital infection and preterm birth predictive markers

Apesar dos avanços na área da Obstetrícia, a prematuridade ainda é a principal causa de morbidade e mortalidade neonatal. Esforços continuam sendo feitos na busca de marcadores que possam predizer tal evento e, assim, evitar o parto prematuro. A presente revisão abordou a relação da infecção genital com a prematuridade e sua influência nos resultados dos principais indicadores preditivos do parto prematuro, bem como a eficácia da antibioticoterapia. Os estudos revisados sugerem que o tratamento da vaginose bacteriana relaciona-se a resultados satisfatórios para a prevenção da prematuridade somente se realizado na primeira metade da gestação. A alteração dos testes preditivos não indica, por si só, o uso de antibióticos.

Despite advances in the field of Obstetrics, prematurity is still responsible for the leading cause of neonatal morbidity and mortality. Efforts are still being made in the search for markers that can predict such an event and thus prevent premature delivery. This review explores the relationship of genital infection with preterm birth and its influence on the results of the main preterm birth predictive markers, as well as the effectiveness of antibiotics. The revised studies suggest that treatment of bacterial vaginosis relates to satisfactory results for the prevention of preterm performed only if the first half of pregnancy. The change of predictive tests not indicates, by itself, the use of antibiotics.

Sexually transmitted infections, bacterial vaginosis, and candidiasis in women of reproductive age in rural Northeast Brazil: a population-based study

Population-based data on sexually transmitted infections (STI), bacterial vaginosis (BV), and candidiasis reflect the epidemiological situation more accurately than studies performed in specific populations, but such data are scarce. To determine the prevalence of STI, BV, and candidiasis among women of reproductive age from a resource-poor community in Northeast Brazil, a population-based cross sectional study was undertaken. All women from seven hamlets and the centre of Pacoti municipality in the state of Ceará, aged 12 to 49 years, were invited to participate. The women were asked about socio-demographic characteristics and genital symptoms, and thereafter examined gynaecologically. Laboratory testing included polymerase chain reaction (PCR) for human papillomavirus (HPV), ligase chain reaction (LCR) for Chlamydia trachomatis and Neisseria gonorrhoeae, ELISA for human immunodeficiency virus (HIV), venereal disease research laboratory (VDRL) and fluorescent treponema antibody absorption test (FTA-ABS) for syphilis, and analysis of wet mounts, gram stains and Pap smears for trichomoniasis, candidiasis, and BV. Only women who had initiated sexual life were included in the analysis (n = 592). The prevalences of STI were: HPV 11.7 percent (95 percent confidence interval: 9.3-14.7), chlamydia 4.5 percent (3.0-6.6), trichomoniasis 4.1 percent (2.7-6.1), gonorrhoea 1.2 percent (0.5-2.6), syphilis 0.2 percent (0.0-1.1), and HIV 0 percent. The prevalence of BV and candidiasis was 20 percent (16.9-23.6) and 12.5 percent (10.0-15.5), respectively. The most common gynaecological complaint was lower abdominal pain. STI are common in women in rural Brazil and represent an important health threat in view of the HIV pandemic.

Seroprevalence of human herpesvirus 8 and its association with Kaposi sarcoma in Brazil.

BACKGROUND: Epidemiologic studies have indicated that human herpesvirus 8 is implicated in the development of Kaposi sarcoma in different geographic areas worldwide. GOAL: To provide information on the prevalence of human herpesvirus 8 in Brazil and its association with Kaposi sarcoma. STUDY DESIGN: An immunofluorescence assay was performed to test 1,044 serum samples from 747 blood donors, 73 patients presenting to casualty departments, and 224 patients attending sexually transmitted disease/AIDS clinics. The sexually transmitted disease group was composed of 88 patients with HIV (40 Kaposi sarcoma positive, 48 Kaposi sarcoma negative) and 136 patients without HIV. RESULTS: Antibodies to human herpesvirus 8-latent nuclear antigens were found in 34 blood donors (4.6%), and in seven casualty patients (9.6%). The highest frequency of human herpesvirus 8 antibodies was found in the sexually transmitted disease group: 32 HIV-positive patients with Kaposi sarcoma (80%) and seven patients without Kaposi sarcoma (14.6%). CONCLUSION: The presence of human herpesvirus 8 in patients with HIV was strongly associated with Kaposi sarcoma (odds ratio, 23.4; 95% CI, 7.7-71.4), male gender, homosexual or bisexual orientation, and hepatitis B virus infection, but not with the other sexually transmitted diseases that were investigated.

Vaginal infections in pregnant women in Jamaica: prevalence and risk factors.

Trichomoniasis, bacterial vaginosis (BV) and candidiasis are reproductive tract infections (RTIs) of the vagina. We conducted a cross-sectional study in 4 prenatal clinics in Kingston, Jamaica, to estimate the prevalence of these infections and the risk factors that may facilitate their transmission among pregnant women. Of the 269 women studied, 18.0% had culture-positive trichomoniasis, 44.1% had BV (Nugent score > or = 7) and 30.7% were positive for candidiasis by wet mount. A multiple logistic regression analysis showed that having a malodorous discharge was associated with trichomoniasis (odd ratios [OR]=3.9, confidence intervals [CI]=1.04-14.7) and BV (OR=3.4, CI=1.3-8.7). Women who took action to prevent HIV infection had lower BV prevalence (OR=0.34, CI=0.12-0.98). Women who were employed were less likely to have any of the infections (OR=0.61, CI=0.36-1.03). The strong association of a symptomatic presentation with trichomoniasis and BV suggests the merit of considering syndromic management of vaginitis in this population.

Sexual behaviour and infection rates for HIV, blood-borne and sexually transmitted infections among patients attending drug treatment centres in Rio de Janeiro, Brazil.

A survey was carried out in 2 drug use treatment centres (TCs) in Rio de Janeiro, Brazil, to assess risk behaviours, HIV infection and other sexually transmitted infections/blood-borne infections (STIs/BBIs). Two hundred and twenty-five drug users (195 males and 30 females) were interviewed and clinically examined, and their blood and urine were tested for STIs/BBIs. Prevalences (%) for these infections were as follows--HIV: 0.9, hepatitis B virus (HBV): 14.7, hepatitis C virus (HCV): 5.8, syphilis: 5.3, gonorrhoea/chlamydia (CT/NG): 4.7. In bivariate analyses CT/NG infection was associated with younger age (P=0.003); current genitourinary symptoms (odds ratio [OR]=6.2) and a mainly illegal source of income (OR=9.1). Hepatitis C infection was associated with a history of ever having injected any drug (OR=19.6), and with each one of the injected drugs. After multiple logistic regression, lower educational level (adjusted odds ratio [AOR]=3.70) and 'ever having injected drugs' (AOR=3.69) remained as independent risk factors for hepatitis B infection. In conclusion, TCs must implement programmes directed towards the prevention of STIs/BBIs.

Characterization of an outbreak of tetM-containing Neisseria gonorrhoeae in Argentina.

Phenotypic and molecular characterization of an outbreak of 9 Neisseria gonorrhoeae (NG) isolates exhibiting high-level plasmid mediated resistance to penicillin and tetracycline (PP-TRNG) that took place in Tandil, Argentina between February and April 1995. Comparison with the patterns of the 3 PP-TRNG strains previously isolated were made. We determined the following markers for each strain: antimicrobial susceptibility, serogroup, auxotype, plasmid profile, presence of tetM determinant and restriction pattern of the tetM-containing plasmid. Antimicrobial tests values were: tetracycline disk diameter 12-14 mm, minimum inhibitory concentration (MIC) 32 micrograms/ml; penicillin disk diameter 6 mm, MIC 32 micrograms/ml and sensitive by both methods to spectinomycin, cefuroxime, ceftriaxone and ciprofloxacin. All isolates were of the same serogroup (WI). Ten of the strains, including the 9 from Tandil outbreak, were arginine-requiring, while the other 2 were methionine and arginine-requiring. All of them demonstrate the same plasmid profile (2.6, 3.2, 25.2 MDa). They were positive for the tetM determinant and the restriction analysis identified it is a Dutch-type plasmid. In spite of the temporal and geographical dispersion, PP-TRNG strains in Argentina seem to be highly homogeneous in terms of antimicrobial susceptibility, serogroup, plasmid profiles and even auxotype.

PIP: This study determines the phenotypic and molecular characterization of an outbreak of 9 Neisseria gonorrhea isolates exhibiting high-level plasmid-mediated resistance to penicillin and tetracycline (PP-TRNG) that took place in Tandil, Argentina. Subjects included patients attending Tandil's Sanatamarina Hospital. Individuals infected with sexually transmitted disease were examined using a standardized questionnaire. Results show that all isolates produced B-lactamase, were penicillin resistant (disk zone diameter 6 mm, MIC 32 mcg/ml) and high-level tetracycline resistant (disk zone diameter 12-14 mm, MIC 32 mcg/ml). Moreover, all strains were fully sensitive to cefuroxime, ceftriaxone, ciprofloxacin, and spectinomycin; while autotype and serogroup results showed that all the strains were arginine-requiring and of serogroup WI. In spite of the temporal and geographical dispersion, PP-TRNG strains in Argentina seem to be highly homogeneous in terms of antimicrobial susceptibility, serogroup, plasmid profiles, and even auxotype.

Risk factors for herpes simplex virus type 2 infection among female commercial sex workers in Mexico City.

A scarce number of studies have been carried out to determine the epidemiology of herpes simplex virus type 2 (HSV-2) infection in female sex workers (FSWs). The objective of this study was to examine the correlates of infection for HSV-2 with socioeconomic and demographic characteristics, sexual behaviour and history of sexually transmitted diseases (STDs) among FSWs in Mexico City. A sample frame of commercial sex work sites was constructed during the fall of 1992. Sites identified were streets, bars and massage parlours. During 1993 we surveyed 757 FSWs aged 18-76 years, from a random sample of sites. Participating women provided a blood sample and answered a standardized questionnaire. HSV-2 antibodies were identified based on a Western blot assay, using type-specific recombinant glycoprotein gG2. In a multivariate analysis, the presence of HSV-2 antibodies was correlated (P < 0.005) with increasing age and time working as prostitutes, low education, street working site and positive serology for syphilis. The results showed that the working site and the education level are contextual variables related to the risk of HSV-2 infection, where poorly educated and street FSWs had the highest probability of infection. Characteristics that represent periods of exposure to the virus as age and time working in prostitution were predictors of the HSV-2 infection.

PIP: The authors investigated the relationship between herpes simplex virus type 2 (HSV-2) infection and socioeconomic and demographic characteristics, sexual behavior, and history of STDs among female prostitutes in Mexico City. During 1993, 757 female prostitutes aged 18-76 years, of mean age 28.5 years, from a random selection of prostitution sites provided blood samples and answered a standardized questionnaire. The presence of HSV-2 antibodies was identified through Western blot assay, using type-specific recombinant glycoprotein gG2. Overall seroprevalences for the study population were 65.1%, 0.6%, 3%, and 6.4% for HSV-2, HIV, hepatitis B virus, and syphilis, respectively. There was no significant correlation between HIV and HSV-2 serological results, although all 5 HIV-seropositive women were HSV-2 seropositive. In a multivariate analysis, the presence of HSV-2 antibodies was correlated with relatively higher age and longer time working as prostitutes, low education, prostitution at a street site, and positive serology for syphilis.

Prevalence of gonococcal and chlamydial infections in commercial sex workers in a Peruvian Amazon city.

BACKGROUND: Iquitos Peru, a densely populated port city housing both a large military base and a booming tourist industry, provides a thriving market for commercial sex and, consequently, sexually transmitted disease (STD). The purpose of this study was to characterize the prevalence of gonococcal and chlamydial infections among commercial sex workers (CSWs) and to correlate those findings with social/behavioral characteristics. METHODS: One hundred CSWs, recruited through street and brothel outreach, were administered questionnaires. Urine specimens were collected for gonorrhea and chlamydia testing using ligase chain reaction assays. RESULTS: Twenty-eight percent of CSWs were positive for chlamydia (22%) or gonorrhea (14%). Registered CSWs were more likely to have worked more than 5 years (p = 0.03), report 10 or more partners (p = 0.002), and work in brothels (p < 0.001). Significant associations were also noted between infection status and age, with adolescents at increased risk (odds ratio [OR] = 4.13, p = 0.001), and duration of employment, with those employed less than 5 years at increased risk (OR = 3.72, p = 0.04). The latter association, however, was because of age. Also, most CSWs believed themselves to be at no/small risk or didn't know their risk of future gonococcal infection (30%/12% and 25%, respectively) and AIDS (25%/8% and 35%, respectively), with 11% perceiving AIDS as more of a threat. CONCLUSIONS: High infection rates, lack of knowledge regarding STD/HIV risk assessment, and other high-risk behavior prevalent among this population stress the need for STD intervention. The study further suggests that educational/risk assessment programs and risk reduction interventions could be successful.

PIP: This study aims to characterize the prevalence of gonococcal and chlamydial infections among commercial sex workers (CSWs) in Iquitos, Peru, which provides a thriving market for CSWs and, consequently, sexually transmitted diseases (STDs) and to correlate those findings with social/behavioral characteristics. About 100 CSWs, recruited through street (n = 37) and brothel outreach (n = 67), were interviewed through questionnaires. Urine specimens were collected for gonorrhea and chlamydial testing. Findings revealed that registered CSWs were significantly more likely to have worked in the sex trade for more than 5 years, report 10 or more sex partners per week, and to work in brothels. Nonetheless, there were no significant differences in age, average charge for sex, or STD prevalence between registered and unregistered CSWs. Overall, 28% of CSWs were positive for chlamydia (22%) and gonorrhea (14%). Furthermore, a number of CSWs stated that they did not know whether they were at risk or assessed their risk as being low for contracting gonorrhea or AIDS. There was no significant association between self-perception of STD risk and STD prevalence. High infection rates, lack of knowledge regarding HIV/AIDS and STD risk assessment, and other high-risk behaviors prevalent among this population stress the need for STD intervention programs and risk reduction behavior.

Sexual practices and prevalence of HIV, HTLV-I/II, and Treponema pallidum among clandestine female sex workers in Lima, Peru.

BACKGROUND AND OBJECTIVES: A survey was conducted to determine the sexual behavior practices and prevalence of HIV-1, HTLV-I/II, and T. pallidum infections among unlicensed female sex workers (FSWs) in Lima, Peru. GOAL OF THIS STUDY: To assess the role of unlicensed FSWs as a potential source of retroviral and T. pallidum infection. STUDY DESIGN: Female sex workers from 15 brothels were enrolled. Sera samples were obtained and tested for antibodies to HIV-1, HTLV-I, and Treponema pallidum. RESULTS: Of 158 FSWs studied, all were negative for HIV-1, 6 were positive for HTLV-I, and 5 were positive for Treponema pallidum. Of their male clients, 75% used condoms, whereas only 3% reported condom use with their steady partners. When condoms were always used by clients, the history of a sexually transmitted disease was significantly reduced (p < 0.01), and the prevalence of HTLV-I (p < 0.05) and syphilis was lower among these workers. CONCLUSION: Data suggested that the low rate of sexually transmitted diseases among FSWs reflected the high rate of condom use by their male clients.

PIP: A survey was conducted to determine the prevalence of HIV-I, human T cell leukemia virus I and II (HTLV-I/II), and Treponema pallidum infection and the associated risk factors for the transmission of these sexually transmitted diseases (STDs) among unlicensed female sex workers (FSWs) in Lima, Peru, to further define their role as a potential source of infection. Unlicensed FSWs from 15 brothels were enrolled in this study from March to June 1994. Serum samples were collected and tested for antibodies to HIV-I, HTLV-I, HTLV-II, and Treponema pallidum. Results revealed that of the 158 FSWs studied, all were negative for HIV-I; 6 were positive for HTLV-I, and 5 had T. pallidum antibodies. Of their male clients, 75% had used condoms for the past 6 months, whereas only 3% reported condom use with their steady partners. Among the workers who stated that condoms were always used, the frequency of a history of STDs, including genital ulcers and inguinal adenopathies, was lower compared to occasional users. Similarly, the prevalence of HTLV-I infection and syphilis was lower among these workers. In conclusion, the study results suggested that the low rate of STDs among FSWs reflected a high rate of condom use.

Country watch: Cuba.

PIP: Health authorities in Cuba made a serious effort to fight HIV/AIDS in their country. In 1986, the government launched a National Programme of Control and Prevention of HIV/AIDS, aimed at controlling the epidemic and providing quality of care for HIV-positive people. Initially, people with HIV/AIDS (PHA) were interned in sanitariums to prevent HIV infection from spreading further. The sanitariums provided good medical and psychological support. However, ambulatory care was introduced in 1993, mitigating the mandatory character of the original system and focusing more on PHA. Additional services were made available to PHA in December 1998 with the creation of a National Centre for the Prevention of Sexually Transmitted Disease/HIV/AIDS, an integral part of the Ministry of Public Health. The center offers an AIDS prevention hotline and counseling services that include a pilot project, ¿Mobile Project¿, an outreach project for people at risk. The PHA Project was launched in March 1999 with a workshop for 30 PHA from Havana; a guide, "Living with HIV", was created to address the problem of unavailability of information concerning the disease. The guide discusses basic clinical information about HIV/AIDS; PHA and their social environment; nutrition, diet, and hygiene; sexuality; and legal aspects.^ieng
