ABSTRACT

Gestational syphilis (GS) in adolescents is a challenge for Brazilian public health, with high incidence rates. Testing, diagnosis and treatment of sexual partners is essential to interrupt the chain of transmission, but since 2017 it is no longer a criterion for the proper treatment of pregnant women. We sought to analyze and synthesize the knowledge produced about the health care of sexual partners of adolescents with GS in Brazil. We carried out a systematic review in the BVS, SciELO and PubMed databases, selecting articles that addressed GS and/or congenital syphilis (CS) in adolescents aged 15 to 19 years and that included information about sexual partners. Forty-one articles were comprehensively analyzed using the WebQDA software and classified into two categories: a) Approach to sexual partners during prenatal care, and b) The role of sexual partners in the transmission cycle of GS and CS. The studies show that the partner's approach is deficient, with a lack of data on the sociodemographic profile and information on testing and treatment. In the context of Primary Health Care, there are no studies that address factors inherent to the context of vulnerability of sexual partners in relation to coping with syphilis.


A sífilis gestacional (SG) em adolescentes é um desafio para a saúde pública brasileira, com elevadas taxas de incidência. A testagem, diagnóstico e tratamento dos parceiros sexuais é indispensável para interromper a cadeia de transmissão, mas desde 2017 deixou de ser critério para o tratamento adequado da gestante. Buscamos analisar e sintetizar o conhecimento produzido sobre a atenção à saúde de parceiros sexuais de adolescentes com SG no Brasil. Realizamos uma revisão integrativa nas bases de dados BVS, SciELO e PubMed, selecionando artigos que abordavam SG e/ou sífilis congênita (SC) em adolescentes de 15 a 19 anos e que incluíam informações sobre os parceiros sexuais. Quarenta e um artigos foram analisados compreensivamente com auxílio do software WebQDA e classificados em duas categorias: (a) Abordagem dos parceiros sexuais no pré-natal, e (b) Papel dos parceiros sexuais no ciclo de transmissão da SG e da SC. Os estudos evidenciam que a abordagem do parceiro é deficitária, com ausência de dados sobre o perfil sociodemográfico e informações sobre testagem e tratamento. No âmbito da atenção primária à saúde não se encontram estudos que abordem fatores inerentes ao contexto de vulnerabilidade dos parceiros sexuais em relação ao enfrentamento da sífilis.

ABSTRACT

INTRODUCTION: Congenital syphilis (CS) is preventable through timely antenatal care (ANC), syphilis screening and treatment among pregnant women. Robust CS surveillance can identify gaps in this prevention cascade. We reviewed CS cases reported to the South African notifiable medical conditions surveillance system (NMCSS) from January 2020 to June 2022. METHODS: CS cases are reported using a case notification form (CNF) containing limited infant demographic and clinical characteristics. During January 2020-June 2022, healthcare workers supplemented CNFs with a case investigation form (CIF) containing maternal and infant testing and treatment information. We describe CS cases with/without a matching CIF and gaps in the CS prevention cascade among those with clinical information. FINDINGS: During January 2020-June 2022, 938 CS cases were reported to the NMCSS with a median age of 1 day (interquartile range: 0-5). Nine percent were diagnosed based on clinical signs and symptoms only. During January 2020-June 2022, 667 CIFs were reported with 51% (343) successfully matched to a CNF. Only 57% of mothers of infants with a matching CIF had an ANC booking visit (entry into ANC). Overall, 87% of mothers were tested for syphilis increasing to 98% among mothers with an ANC booking visit. Median time between first syphilis test and delivery was 16 days overall increasing to 82 days among mothers with an ANC booking visit. DISCUSSION: Only 37% of CS cases had accompanying clinical information to support evaluation of the prevention cascade. Mothers with an ANC booking visit had increased syphilis screening and time before delivery to allow for adequate treatment.


Untreated maternal syphilis has devastating consequences for the foetus. Congenital syphilis (CS) is preventable through timely maternal screening and treatment with robust surveillance. We evaluated CS surveillance data to identify gaps in CS surveillance and in the prevention cascade in South Africa.

ABSTRACT

The origins of treponemal diseases have long remained unknown, especially considering the sudden onset of the first syphilis epidemic in the late 15th century in Europe and its hypothesized arrival from the Americas with Columbus' expeditions1,2. Recently, ancient DNA evidence has revealed various treponemal infections circulating in early modern Europe and colonial-era Mexico3-6. However, there has been to our knowledge no genomic evidence of treponematosis recovered from either the Americas or the Old World that can be reliably dated to the time before the first trans-Atlantic contacts. Here, we present treponemal genomes from nearly 2,000-year-old human remains from Brazil. We reconstruct four ancient genomes of a prehistoric treponemal pathogen, most closely related to the bejel-causing agent Treponema pallidum endemicum. Contradicting the modern day geographical niche of bejel in the arid regions of the world, the results call into question the previous palaeopathological characterization of treponeme subspecies and showcase their adaptive potential. A high-coverage genome is used to improve molecular clock date estimations, placing the divergence of modern T. pallidum subspecies firmly in pre-Columbian times. Overall, our study demonstrates the opportunities within archaeogenetics to uncover key events in pathogen evolution and emergence, paving the way to new hypotheses on the origin and spread of treponematoses.

ABSTRACT

Background and Objectives: Syphilis is a sexually transmitted infection with low-cost and accessible treatment; however, it is considered a public health problem. Further studies are needed to improve knowledge about the factors that may contribute to the mother-to-child transmission of syphilis. Given its high detection rate in pregnant women and the possible adverse events of syphilis in Brazil, the objective was to evaluate the association of individual and clinical characteristics of syphilis with the incidence of congenital syphilis in pregnant women. Methods: This retrospective study was performed in a medium-size municipality in the State of São Paulo. Notification forms from the Notifiable Diseases Information System were used and the occurrence of congenital syphilis was the outcome of the study. Bivariate analyses and logistic regression were performed with variables that obtained p values <0.25. Results: Most pregnant women were 20-34 years old (62.2%) and had white skin (63.2%) and incomplete elementary schooling (35.4%). The occurrence of congenital syphilis was associated with the maternal syphilis diagnosis (p<0,001) and with not performing the treponemal test during the prenatal examination (p =0.014). There was a greater risk for the occurrence of congenital syphilis in cases with late diagnosis during pregnancy (OR=16.48; 95%CI 3.22-84.26) and tertiary/latent clinical classification (OR=7.62; 95%CI 1.40-41.54). Conclusion: Maternal diagnosis in the third trimester of pregnancy and tertiary/latent clinical classification were the main risk factors for the occurrence of congenital syphilis, reinforcing the importance of a quality prenatal examination performed timely.(AU)


Justificativa e Objetivos: A sífilis é uma Infecção Sexualmente Transmissível, com tratamento de baixo custo e acessível; porém, ela é considerada um problema de saúde pública. Para aprimorar o conhecimento sobre os fatores que podem contribuir para transmissão vertical da sífilis, mais estudos são necessários. Diante da elevada taxa de detecção em gestantes e dos possíveis eventos adversos da sífilis no Brasil, o objetivo foi avaliar a associação das características individuais e clínicas de sífilis com a incidência de sífilis congênita em gestantes. Métodos: Este estudo retrospectivo foi realizado em um município de médio porte no Estado de São Paulo. Foram usadas as fichas de notificação do Sistema de Informação de Agravos de Notificação e o desfecho do estudo foi a ocorrência de sífilis congênita. Foram realizadas análises bivariadas e regressão logística com as variáveis que obtiveram valores de p<0,25. Resultados: As maioria das gestantes tinha 20-34 anos (62,2%), era branca (63,2%), com escolaridade fundamental incompleta (35,4%). A ocorrência de sífilis congênita esteve associada ao diagnóstico de sífilis materno no terceiro trimestre de gestação (p<0,001) e com a não realização de teste treponêmico durante o pré-natal (p=0,014). Houve maior risco para a ocorrência de sífilis congênita os casos com diagnóstico tardio na gestação (OR=16,48; IC95% 3,22-84,26) e classificação clínica terciária/latente (OR=7,62; IC95% 1,40-41,54). Conclusão: Os principais fatores de risco para ocorrência de sífilis congênita foram o diagnóstico materno no terceiro trimestre de gestação e classificação clínica terciária/latente, reforçando a importância de um exame pré-natal de qualidade e em tempo oportuno.(AU)

ABSTRACT

Introduction: Syphilis is an infectious systemic disease caused by the bacterium Treponema pallidum. The Amaury de Medeiros Integrated University Health Center in Recife is a reference maternity hospital for high-risk pregnancies and the management of the most common Sexually Transmitted Infections during prenatal care, including Gestational Syphilis and Congenital Syphilis. Objective: To determine the epidemiological profile of the population exposed to these conditions, the rate of Gestational Syphilis detection, the incidence of Congenital Syphilis, and the associated unfavorable outcomes in Amaury de Medeiros Integrated University Health Center between January 2019 and December 2021. Methods: This retrospective cohort study included pregnant women and neonates diagnosed with syphilis at Amaury de Medeiros Integrated University Health Center. Data were collected from the Notification/Investigation Forms for Gestational Syphilis and Congenital Syphilis, between January 2019 and December 2021. Results: At Amaury de Medeiros Integrated University Health Center, 463 cases of Gestational Syphilis and 296 of Congenital Syphilis were reported. During the three-year study, 4444, 4360, and 4265 live births were recorded, confirming the Gestational Syphilis detection rates ­ 33.30, 36.92, and 36.10 per 1000 live births, with the incidence of Congenital Syphilis being 26.1, 21.33, and 20.39 per 1000 live births. Pregnant women in their third trimester who were brown, had incomplete primary education, and lived in an urban area were the main sociodemographic variables. In total, 217 (73.3%) patients were diagnosed with Gestational Syphilis during or after delivery, indicating a low prenatal coverage (70.6%). In terms of the progression of Congenital Syphilis, unfavorable outcomes was found in 40 (13.5%) patients, including 16 (40%) abortions, 10 (25%) stillbirths, nine (22.5%) deaths from Congenital Syphilis, and 5 (12.5%) deaths from other causes. Conclusion: Gestational Syphilis detection rates and Congenital Syphilis incidence remain alarming, with abortions and stillbirths being the most common unfavorable outcomes. To change the dramatic situation of Congenital Syphilis in Brazil, the associated factors point to a poor quality of prenatal care and an urgent need to change public policies for pregnant women and newborns, in conjunction with socioeconomic assistance

ABSTRACT

BACKGROUND: Gay, bisexual and other men who have sex with men (gbMSM) who attend STI clinics represent an easily accessible population for promoting HIV prevention interventions. We examined characteristics of gbMSM STI clinic attendees to identify those who could most benefit from pre-exposure prophylaxis (PrEP). SETTING: GbMSM STI clinic attendees in British Columbia (BC), Canada. METHODS: A clinical electronic charting system of STI clinics in BC was used to identify gbMSM from 2004 to 2017. Incident HIV cases were defined as testers who had at least one HIV-negative test and a subsequent HIV-positive test. Seroconversion rates were calculated by risk factor variables and by year. Cox proportional hazards regression was used to identify independent predictors of HIV seroconversion. RESULTS: There were 9,038 gbMSM included, of whom 257 HIV seroconverted over the study period and 8,781 remained negative HIV testers, contributing 650.8 and 29,591.0 person-years to the analysis, respectively. The overall rate of seroconversion was 0.85 per 100 person-years (95% CI: 0.75-0.96). Incidence rates were higher among patients reporting >5 partners in the previous six months, inconsistent condom use, or having a partner living with HIV and who had a previous or concurrent diagnosis of rectal gonorrhea or rectal chlamydia. gbMSM presenting with two STIs such as rectal gonorrhea and syphilis (3.59/100 person-years [95%CI: 2.33-5.22]) or rectal chlamydia and syphilis (3.01/100 person-years [95%CI: 2.00-4.29]) had the highest incidence rates. CONCLUSION: gbMSM with preceding or concurrent rectal STI diagnoses or syphilis had higher rates of HIV seroconversion. The data support the inclusion of specific STI diagnoses as an indication for PrEP.

ABSTRACT

Over the last decade, syphilis diagnoses among men-who-have-sex-with-men (MSM) have strongly increased in Europe. Understanding the drivers of the ongoing epidemic may aid to curb transmissions. In order to identify the drivers of syphilis transmission in MSM in Switzerland between 2006 and 2017 as well as the effect of potential interventions, we set up an epidemiological model stratified by syphilis stage, HIV-diagnosis, and behavioral factors to account for syphilis infectiousness and risk for transmission. In the main model, we used 'reported non-steady partners' (nsP) as the main proxy for sexual risk. We parameterized the model using data from the Swiss HIV Cohort Study, Swiss Voluntary Counselling and Testing center, cross-sectional surveys among the Swiss MSM population, and published syphilis notifications from the Federal Office of Public Health. The main model reproduced the increase in syphilis diagnoses from 168 cases in 2006 to 418 cases in 2017. It estimated that between 2006 and 2017, MSM with HIV diagnosis had 45.9 times the median syphilis incidence of MSM without HIV diagnosis. Defining risk as condomless anal intercourse with nsP decreased model accuracy (sum of squared weighted residuals, 378.8 vs. 148.3). Counterfactual scenarios suggested that increasing screening of MSM without HIV diagnosis and with nsP from once every two years to twice per year may reduce syphilis incidence (at most 12.8% reduction by 2017). Whereas, increasing screening among MSM with HIV diagnosis and with nsP from once per year to twice per year may substantially reduce syphilis incidence over time (at least 63.5% reduction by 2017). The model suggests that reporting nsP regardless of condom use is suitable for risk stratification when modelling syphilis transmission. More frequent screening of MSM with HIV diagnosis, particularly those with nsP may aid to curb syphilis transmission.

ABSTRACT

BACKGROUND: Children may acquire syphilis by nonsexual contact as a consequence of close and repetitive contact with mucosal or skin lesions of people with active syphilis. METHODS: Prospective cohort study of pediatric patients with acquired syphilis by nonsexual contact. Demographics, clinical findings, posttreatment serology development and general laboratory data were collected. Sexual transmission was ruled out after a careful medical and psychosocial evaluation of the patient and his/her family. RESULTS: Twenty-four patients were included in the study. Mean age at diagnosis was 4.2 years old. All of them came from overcrowded households with poor hygiene conditions. The most frequent reason for consultations was secondary syphilis skin lesions (79.2%). The psychosocial evaluation of children and their families did not reveal signs of sexual abuse in any of the cases. Seventy-eight families and their cohabitants were evaluated, 23 (29.5%) resulted positive for rapid plasma reagin and treponemal test of hemagglutination; 60.9% of the cases were asymptomatic. The symptomatic relatives showed lesions of secondary syphilis. A sustained fall on nontreponemal antibodies titer (rapid plasma reagin) was observed after treatment, becoming negative in 6/24 (25%) cases within 12 months posttreatment. DISCUSSION: Following evaluation, it was considered that sexual abuse was unlikely. However, if examination and psychosocial evaluation do not support it, other ways of transmission must be considered. Overcrowded and poor household conditions boost the risks for nonsexual treponema transmission. An infected member of the family or a caretaker are a particular risk to an infant due to common practices such as using saliva to moisten the rubber nipples of the milk bottles or trying the food temperature using the lips before feeding the infants.

ABSTRACT

Abstract Objectives: to calculate the prevalence and rate per 1,000 live births of sexually transmitted infections (STI) in pregnant women at a public maternity hospital in Salvador. Methods: this descriptive, cross-sectional study retrospectively collected data from compulsory notifications and medical records of pregnant women with STI seen at a maternity hospital in northeastern Brazil between 2014 and 2017 (n = 520). Prevalence and rate per 1,000 live births were estimated for hepatitis B, hepatitis C, HIV, and syphilis. Associations between STI and other clinical and sociodemographic variables were investigated. Results: most pregnant women were born and resided in Salvador, presented a mean age of 26.4 years, self-reported mixed-race and had unplanned pregnancies. Prevalence and rates per 1,000 live births were, respectively: 0.26% and 3.39 for hepatitis B, 0.06% and 0.79 for hepatitis C, 0.47% and 6.23 for HIV, and 2.46% and 32.2 for syphilis. Conclusion: higher prevalence and rates of infection per 1,000 live births were seen at the maternity hospital in northeastern Brazil compared to official data provided by the Brazilian government, notably with regard to HIV and syphilis. The appropriate epidemiological notification of STI, especially in pregnant women, enables the elaboration of effective preventive strategies incorporating specific sociodemographic and clinical characteristics.


Resumo Objetivos: calcular a prevalência e as taxas por 1000 nascidos vivos de infecções sexualmente transmissíveis (IST) em gestantes de uma maternidade pública de Salvador. Métodos: estudo transversal, descritivo, com dados coletados retrospectivamente a partir das fichas de notificação dos agravos e dos prontuários de todas as gestantes com IST atendidas na maternidade, entre os anos de 2014 e 2017 (n=520). Foram calculadas as prevalências e as taxas por 1000 nascidos vivos de hepatite B, hepatite C, HIV e sífilis para a população de gestantes da maternidade. Associações entre as IST e demais variáveis clínicas e sociodemográficas também foram investigadas. Resultados: a maioria das gestantes era natural e residente de Salvador, pardas, com idade média de 26,4 anos e que não planejaram a gravidez. As prevalências e as taxas por 1000 nascidos vivos foram respectivamente: 0,26% e 3,39 para hepatite B, 0,06% e 0,79 para hepatite C, 0,47% e 6,23 para HIV e 2,46% e 32,2 para sífilis. Conclusão: a maternidade apresenta prevalências e taxas por 1000 nascidos vivos superiores aos dados oficiais do governo brasileiro, especialmente para HIV e sífilis. A correta notificação epidemiológica desses agravos, especialmente em gestantes, permite o desenvolvimento de estratégias preventivas mais eficientes e com enfoque nas características sociodemográficas e clínicas das pacientes.

ABSTRACT

OBJECTIVE: There have been significant successes in the fight against HIV/AIDS due to the access to rapid HIV testing, interventions to reduce the mother-to-child transmission (MTCT) risk, potent and effective antiviral medications, and other biomedical prevention strategies. The purpose of this work is to demonstrate that Puerto Rico eliminated Mother-to-Child Transmission of HIV (MTCT) following the 2017 World Health Organization (WHO) criteria for validating the elimination of MTCT and Syphilis. METHODS: Existing epidemiological data from Puerto Rico was used to document the elimination of MTCT and Syphilis. Data to calculate the indicators was obtained from the various divisions of the Puerto Rico Department of Health, including vital statistics, surveillance data, and programmatic outcomes. RESULTS: Puerto Rico eliminated MTCT and syphilis, according to the WHO indicators, earlier than other countries. We can trace the outcomes to 1994 using the incidence rate of perinatally-acquired HIV of <50/100,000; to 2007 using HIV perinatal transmission rates for non-breastfeeding countries (<2%), to 2008 using 90% of women receiving ART at delivery, and to 2005 using the incidence rate of congenital syphilis of <50/100,000. CONCLUSION: Not only have we eliminated the MTCT of HIV and syphilis, but the efforts have been sustained since 2000. The elimination of transmission of infectious diseases requires the intersection of scientific feasibility, coordinated interventions, and political will, successfully attained in Puerto Rico.

ABSTRACT

Japan has had a substantial increase in syphilis cases since 2013. However, research on the genomic features of the Treponema pallidum subspecies pallidum (TPA) strains from these cases has been limited. Here, we elucidated the genetic variations and relationships between TPA strains in Japan (detected between 2014 and 2018) and other countries by whole-genome sequencing and phylogenetic analyses, including syphilis epidemiological surveillance data and information on patient sexual orientation. Seventeen of the 20 strains in Japan were SS14- and the remaining 3 were Nichols-lineage. Sixteen of the 17 SS14-lineage strains were classified into previously reported Sub-lineage 1B. Sub-lineage 1B strains in Japan have formed distinct sub-clusters of strains from heterosexuals and strains from men who have sex with men. These strains were closely related to reported TPA strains in China, forming an East-Asian cluster. However, those strains in these countries evolved independently after diverging from their most recent common ancestor and expanded their genetic diversity during the time of syphilis outbreak in each country. The genetic difference between the TPA strains in these countries was characterized by single-nucleotide-polymorphism analyses of their penicillin binding protein genes. Taken together, our results elucidated the detailed phylogenetic features and transmission networks of syphilis.

ABSTRACT

BACKGROUND: The increasing incidence of syphilis worldwide has called attention to the risk of transmission by transfusion. AIMS: To determine the prevalence of active syphilis in blood donors and characterise the serological profile of syphilis-positive donors. METHODS: Samples positive for Treponema pallidum using the chemiluminescent microparticle immunoassay (CMIA) during blood donor screening from 2017 to 2018 were tested by the Venereal Disease Research Laboratory (VDRL) non-treponemal test and for anti-T. pallidum IgM by ELISA (Immunoassay Enzyme test for detection of IgM antibodies). The INNO-LIA Syphilis test (Line Immuno Assay solid test for confirmation antibodies to Treponema pallidum) was performed as a confirmatory test on samples that were positive on ELISA-IgM but negative on VDRL. ELISA-IgM (+) samples were also tested for T. pallidum DNA in sera by real-time polymerase chain reaction (PCR). RESULTS: Of 248 542 samples screened, 1679 (0.67%) were positive for syphilis by CMIA. Further analysis was performed on 1144 (68.1%) of these samples. Of those tested, 16% were ELISA IgM(+)/VDRL(+), 16.5% were ELISA IgM(-)/VDRL(+), 4.1% were ELISA IgM(+)/VDRL(-), and 63.4% were ELISA IgM (-)/VDRL(-). The INNO-LIA Syphilis test results were 33 (3%) positive, 2 (0.2%) undetermined and 12 (1%) negative. Of the 230 EIA-IgM(+) samples (20.1%), 5 (2.2%) were PCR positive. The prevalence of active syphilis in 2017 and 2018 was 0.1% and 0.07%, respectively, and overall prevalence of serologic markers for syphilis was highest among male, unmarried, 25-34-year-olds with a high school education and who were first-time donors. CONCLUSION: There is a risk of transfusion-transmitted syphilis in blood banks that exclusively use the VDRL test for donor screening, as is currently the situation in some Brazilian blood centres, as well as in other blood centres around the world.

ABSTRACT

OBJETIVOS: Este estudio tiene como objetivo comprender las relaciones entre el progreso de la cobertura de la Estrategia de Salud de Familia en los nueve estados del noreste y las tasas de detección de sífilis en mujeres embarazadas y congénitas entre 2008 y 2017. MÉTODOS: Se trata de un estudio observacional, descriptivo y transversal en el que se correlacionaron las tasas de detección de sífilis de gestación y sífilis congénita en los estados nororientales y en esta región en su conjunto con la respectiva cobertura media anual de la Estrategia de Salud de Familia. Para ello, se realizó la prueba del coeficiente de correlación de Pearson para estas dos variables utilizando el software del Statistical Package for the Social Sciences 25. RESULTADOS: El análisis estadístico de los datos de los estados permitió identificar que, al igual que en los datos agrupados de la región, a medida que aumentó la cobertura de la Estrategia de Salud de Familia, la tasa de detección de casos de sífilis en mujeres embarazadas y congénitas también aumentó significativamente en la mayoría de los estados, y en la región nordeste en su conjunto. CONCLUSIONES: El Sistema Único de Salud a través de la Estrategia de Salud de Familia ha dado lugar a importantes avances relacionados con el seguimiento del embarazo, el puerperio y el desarrollo infantil, así como en el diagnóstico temprano de infecciones como la sífilis. Sin embargo, además del diagnóstico, se necesitan mejoras significativas en el tratamiento y la prevención de estas enfermedades en la región noreste


OBJETIVOS: Este estudo tem por objetivo conhecer as relações existentes entre o avanço da cobertura da Estratégia Saúde da Família nos nove estados nordestinos e as taxas de detecção da sífilis em gestantes e congênita entre os anos de 2008 e 2017. MÉTODOS: Trata-se de um estudo observacional, descritivo e transversal, em que as taxas de detecção para sífilis na gestação e congênita dos estados do Nordeste e desta região como um todo foram correlacionadas com as respectivas médias anuais de cobertura da Estratégia Saúde da Família. Para isso, foi realizado o teste de coeficiente de correlação de Pearson, para essas duas variáveis, através do software Statistical Package for the Social Sciences 25. RESULTADOS: A análise estatística dos dados estaduais possibilitou identificar que, assim como nos dados agrupados da região, à medida que aumentava a cobertura da ESF, a taxa de detecção dos casos de sífilis em gestantes e congênita também crescia significativamente na maioria dos estados, e na região Nordeste integralmente. CONCLUSÕES: O Sistema Único de Saúde através da Estratégia Saúde da Família tem protagonizado grandes avanços relacionados ao acompanhamento da gestação, puerpério e desenvolvimento infantil, como no diagnóstico precoce de infecções, como a sífilis. Entretanto, além do diagnóstico, é preciso melhorias significativas no tratamento e prevenção destas doenças na região Nordeste


OBJECTIVES: This study aims to verify the relationships between the advancing of coverage of the Family Health Strategy in the nine northeastern states and the rates of detection of syphilis in pregnant women and congenital between the years 2008 and 2017. METHODS: Observational, descriptive and cross-sectional study, in which the detection rates for gestational syphilis and congenital in the nine states of the Northeast and this region as a whole were correlated with the respective annual averages Family Health Strategy coverage. For that, Pearson's correlation coefficient test was performed for these two variables, using the Statistical Package for the Social Sciences 25 software. RESULTS: The statistical analysis of the state data made it possible to identify that, as well as in the grouped data of the region, as the Family Health Strategy coverage increased, the detection rate of syphilis cases in pregnant women and congenital also increased significantly in most states, and in the Northeast region entirely. CONCLUSIONS: The Unified Health System through the Family Health Strategy has made great advances related to the monitoring of pregnancy, puerperium and child development as in the early diagnosis of infections like syphilis. However, in addition to the diagnosis, significant improvements are needed in the treatment and prevention of these diseases in the Northeast region

ABSTRACT

BACKGROUND: The epidemiology of congenital infections is ever changing, with a recent resurgence in syphilis infection rates seen in the UK. Identification of congenital infection is often delayed; early recognition and management of congenital infections is important. Testing modalities and investigations are often limited, leading to missed diagnostic opportunities. METHODS: The SCORTCH (syphilis, cytomegalovirus (CMV), 'other', rubella, toxoplasmosis, chickenpox, herpes simplex virus (HSV) and blood-borne viruses) acronym increases the awareness of clinicians to the increased risk of congenital syphilis, while considering other infectious aetiologies including: zika, malaria, chagas disease, parvovirus, enterovirus, HIV, hepatitis B and C, and human T-lymphotropic virus 1, in addition to the classic congenital infections recognised in the 'TORCH screen' (toxoplasmosis, 'other', rubella, CMV, HSV). The SCORTCH diagnostic approach describes common signs present in infants with congenital infection, details serological testing for mother and infant and important direct diagnostics of the infant. Direct diagnostic investigations include: radiology, ophthalmology, audiology, microbiological and PCR testing for both the infant and placental tissue, the latter also warrants histopathology. CONCLUSION: The traditional 'TORCH screen' focuses on serology-specific investigations, often omits important direct diagnostic testing of the infant, and fails to consider emerging and re-emerging congenital infections. In recognition of syphilis as a re-emerging pathogen and the overlapping clinical presentations of various infectious aetiologies, we advocate for a broader outlook using the SCORTCH diagnostic approach.

ABSTRACT

Objetivo: Este estudo teve como principal objetivo estimar a prevalência de sífilis gestacional e fatores associados à infecção em uma Maternidade no Sul do Brasil no ano de 2018. Métodos: Trata-se de estudo descritivo, transversal, retrospectivo, no qual foram avaliados os testes rápidos para sífilis de todas as gestantes internadas para atenção ao parto ou ao abortamento na Maternidade Carmela Dutra no ano de 2018. Nos casos confirmados de sífilis, foram obtidos dados epidemiológicos, adequação do tratamento, coinfecção pelo HIV e resultados gestacionais. Resultados: Entre os prontuários analisados, 161 (3,6%) foram considerados casos de sífilis materna. A média de idade das gestantes foi de 27,98 (±6,65), 54 (33,5%) eram primigestas, 114 (70,8%) se declararam brancas, 125 (77,5%) estavam em uma união estável e 85 (52,7%) tinham escolaridade até o ensino médio. Quanto ao tratamento, 71 (44%) trataram de maneira adequada e 90 (56%), de maneira inadequada, e 44 (27,3%) delas realizaram o diagnóstico apenas no momento da internação hospitalar. Entre as pacientes que realizaram tratamento inadequado de sífilis, 28 (53,4%) apresentaram títulos iguais ou superiores a 1:8. Entre as pacientes que realizaram teste rápido para HIV na internação, 5 (3,7%) apresentaram coinfecção com a doença. Com relação ao tratamento dos parceiros no pré-natal, 11,8% não realizaram nenhum tipo de tratamento, porém em 66 (41%) prontuários não constava essa informação. Com relação ao desfecho neonatal, 5 (7,4%) pacientes com tratamento inadequado para sífilis tiveram parto prematuro, 5 (7,4%) recém- -nascidos foram de baixo peso e 22 (24,5%) pacientes apresentaram abortamento da gestação. Conclusão: A alta taxa de tratamentos inadequados sugere falhas na assistência pré-natal e indica serem necessárias novas estratégias para reduzir a transmissão de sífilis na gestação.(AU)


Objective: The aim of this study is to estimate the prevalence of maternal syphilis and factors associated with the infection in Carmela Dutra Maternity in 2018. Methods: This is a descriptive, cross-sectional and retrospective study. All of the syphilis rapid-tests on pregnant women admitted for childbirth or miscarriage assistance at Carmela Dutra Maternity in 2018 were evaluated. In the cases of confirmed syphilis infection, the variables were epidemiological data, adequacy of treatment, HIV coinfection and gestational outcomes. Results: Out of all the medical records analyzed, 161 (3.6%) were considered maternal syphilis (MS). The average age of the pregnant women was 27.98 (± 6.65), 54 (33.5%) were primigestae, 114 (70.8%) declared themselves white, 125 (77.5%) were in a stable relationship and 85 (52.7%) had a high school education. Regarding treatment, 71 (44%) were treated adequately and 90 (56%) inadequately. Forty-four (27.3%) were diagnosed only at the time of hospitalization. Amongst patients who had inadequate syphilis treatment, 28 (53.4%) had titers equal to or greater than 1:8. Amongst patients who underwent rapid HIV testing during hospitalization, 5 (3.7%) had HIV coinfection. Regarding the partners treatment during prenatal, 11.8% did not receive any treatment, but 66 (41%) of the medical records did not contain this information. Regarding neonatal outcome, 5 (7.4%) of patients with inadequate treatment for syphilis had premature birth, 5 (7.4%) of newborns were underweight and 22 (24.5%) had miscarriages. Conclusion: The high rate of inadequate treatment suggests failure in prenatal care and indicates that new strategies are necessary to reduce syphilis transmission during pregnancy.(AU)

ABSTRACT

BACKGROUND: Studies investigating the associations of maternal syphilis treatment with birth outcomes mainly concentrated in economically developed areas. Limited data are available in economically underdeveloped areas, such as Jiangxi Province. The study aims to investigate the impact of maternal treatment on birth outcomes in Jiangxi Province, China. METHODS: Data were obtained from the China's Information System of Prevention of Mother-to-Child Transmission in Jiangxi Province. All syphilis infected pregnant women who delivered ≥28 gestational weeks and were registered in this system between 1 January 2013 and 31 December 2019 were enrolled. Pregnancy outcomes were evaluated by group-specific analyses according to their treatment status, adequacy and initiation time. RESULTS: 4210 syphilis infected pregnant women were included in the analyses. Infants born to untreated mothers (n = 1364) were at significantly higher risk for stillbirth (adjusted odds ratio (aOR) = 1.74, 95% CI, 1.01-3.00, P = 0.045), preterm birth (aOR = 1.27, 95% CI, 1.02-1.59, P = 0.034) and low birth weight (LBW) (aOR = 1.44; 95% CI, 1.11-1.86, P = 0.006) than those born to treated mothers (n = 2846) after adjustment for confounding factors. A significantly higher risk of stillbirth (aOR = 3.68; 95% CI, 1.62-8.34, P = 0.002), preterm birth (aOR = 2.26; 95% CI, 1.71-3.00, P < 0.001), LBW (aOR = 2.23; 95% CI, 1.59-3.14, P < 0.001) and congenital syphilis (CS) (aOR = 3.63; 95% CI, 1.80-7.31, P < 0.001) was found in infants exposed to mothers treated inadequately (n = 1299) than those treated adequately (n = 1547). No pregnant women who initiated the treatment in the first trimester (n = 682) delivered a neonatal CS case. Compared with mothers who initiated treatment in the first trimester (n = 682), those initiated in the third trimester (n = 1234) suffered an increased risk of stillbirth (aOR = 4.48; 95% CI, 1.31-15.30, P = 0.017), preterm birth (aOR = 2.34; 95% CI, 1.61-3.40, P < 0.001) and LBW (aOR = 3.25; 95% CI, 1.97-5.37, P < 0.001). CONCLUSIONS: Maternal treatment, especially early and adequate treatment, plays a crucial role in mitigating adverse pregnancy outcomes among syphilis infected women.

ABSTRACT

BACKGROUND: Untreated male partners are a critical source of maternal re-infection. Contact tracing is a good way to identify infection among partners and reduce risk of mother-to-child transmission related to maternal re-infection. This study aimed to analyze the current situation and related factors of contact tracing of syphilis-seropositive pregnant women and syphilis-infection among their male partners. METHOD: Data of syphilis-seropositive pregnant women and their male partners attending clinic for syphilis-screening were obtained from the Shenzhen Program for Prevention of Congenital Syphilis. Contact tracing rate of syphilis-seropositive pregnant women and syphilis prevalence among male partners were counted, and related factors were also analyzed using a random-effects logistic regression model. RESULT: Of the 1299 syphilis-seropositive pregnant women, 74.1% (963/1299) had their male partners receiving syphilis-screening and 19.1% (184/963) of male partners were syphilis-infected. For pregnant women, being divorced (adjusted odds ratio [AOR] =0.39; 95%CI: 0.17-0.87), seeking for emergency services at their first antenatal clinics visits (AOR = 0.58; 95%CI: 0.44-0.77), reporting willingness to notify partner(AOR = 7.65; 95%CI: 4.69-12.49), multi-partners (AOR = 1.38; 95%CI:1.03-1.86) and having a history of drug abuse (AOR = 0.37; 95%CI: 0.14-1.00)were independently associated with successful contact tracing. For male partners, of minority ethnicity (AOR = 4.15; 95%CI: 1.66-10.34), age at first sex>20(AOR = 0.57; 95%CI: 0.37-0.87), reporting multi-partners (AOR = 1.60; 95%CI: 1.04-2.46), having a history of drug abuse (AOR = 4.07; 95%CI: 1.31-12.64) were independently associated with syphilis-infection. In addition, pregnant women with TRUST titer ≥1:8 (AOR = 2.81; 95%CI: 1.87-4.21), having a history of adverse pregnancy outcomes (AOR = 1.70; 95%CI: 1.14-2.53), reporting multi-partners (AOR = 0.43; 95%CI: 0.29-0.64) and reporting the current partner as the source of syphilis (AOR = 5.05; 95%CI: 2.82-9.03) were independently associated with partners' syphilis-infection. CONCLUSION: Contact tracing is feasible and effective in identifying syphilis-infected partners among syphilis-seropositive pregnant women. Contact tracing is associated with many factors such as women's marital status, services at their first antenatal clinics visit and willingness of partner notification. Partners' ethnicity, age at first sex, multi-partners and history of drug abuse as well as women's levels of TRUST titer were associated with partners' syphilis-infection.

ABSTRACT

BACKGROUND: The national rate of syphilis has increased among persons who inject drugs (PWID). Missouri is no exception, with increases in early syphilis (ES), congenital syphilis, and PWID, especially in nonurban counties. METHODS: Disease intervention specialist records for ES cases in Missouri (2012-2018) were examined. Drug use was classified as injection drug use (IDU) (opioid or methamphetamine) or non-IDU (opioid, methamphetamine, or cocaine). Rates were compared based on residence, sex of sex partner, and drug use. RESULTS: Rates of ES in Missouri increased 365%, particularly in small metropolitan and rural areas (1170%). Nonurban areas reported a higher percentage of persons with ES who used injection drugs (12%-15%) compared with urban regions (2%-5%). From 2012 to 2018, women comprised an increasing number of ES cases (8.3%-21%); 93% of women were of childbearing age. Increasingly more women in rural areas with ES also reported IDU during this time (8.4%-21.1%). CONCLUSIONS: As syphilis increases in small metropolitan and rural regions, access to high-quality and outreach-based sexual health services is imperative. Healthcare policy to equip health departments with harm reduction services and drug treatment resources offers an opportunity to impact both syphilis increases as well as health outcomes associated with IDU.

ABSTRACT

Congenital abnormalities cause serious fetal consequences. The term TORCH is used to designate the most common perinatal infections, where: (T) refers to toxoplasmosis, (O) means "others" and includes syphilis, varicella-zoster, parvovirus B19, zika virus (ZIKV), and malaria among others, (R) refers to rubella, (C) relates to cytomegalovirus infection, and (H) to herpes simplex virus infections. Among the main abnormalities identified in neonates exposed to congenital infections are central nervous system (CNS) damage, microcephaly, hearing loss, and ophthalmological impairment, all requiring regular follow-up to monitor its progression. Protein changes such as mutations, post-translational modifications, abundance, structure, and function may indicate a pathological condition before the onset of the first symptoms, allowing early diagnosis and understanding of a particular disease or infection. The term "proteomics" is defined as the science that studies the proteome, which consists of the total protein content of a cell, tissue or organism in a given space and time, including post-translational modifications (PTMs) and interactions between proteins. Currently, quantitative bottom-up proteomic strategies allow rapid and high throughput characterization of complex biological mixtures. Investigating proteome modulation during host-pathogen interaction helps in elucidating the mechanisms of infection and in predicting disease progression. This "molecular battle" between host and pathogen is a key to identify drug targets and diagnostic markers. Here, we conducted a survey on proteomic techniques applied to congenital diseases classified in the terminology "TORCH", including toxoplasmosis, ZIKV, malaria, syphilis, human immunodeficiency virus (HIV), herpes simplex virus (HSV) and human cytomegalovirus (HCVM). We have highlighted proteins and/or protein complexes actively involved in the infection. Most of the proteomic studies reported have been performed in cell line models, and the evaluation of tissues (brain, muscle, and placenta) and biofluids (plasma, serum and urine) in animal models is still underexplored. Moreover, there are a plethora of studies focusing on the pathogen or the host without considering the triad mother-fetus-pathogen as a dynamic and interconnected system.
