Management of syphilis in pregnancy: Knowledge and practices of health care providers and barriers to the control of disease in Teresina, Brazil

Congenital syphilis, syphilis in pregnancy and prenatal care in Brazil: An ecological study

The aim of this research was to evaluate the incidence of congenital syphilis and the ratio between congenital syphilis and syphilis in pregnant women in Brazil according to socioeconomic indicators (inadequate water supply and sanitation; illiteracy at 15 years of age or older; household income per capita; proportion of poor people; Gini index; human development index; and average health expenditure per inhabitant by the health system) and prenatal quality-of-care indicators. We conducted an ecological study using a sample composed of 257 municipalities, each with ≥ 100,000 inhabitants. Data was collected from four public databases: the Brazilian Institute of Geography and Statistics, comprising socioeconomical data from the 2010 census; and the data of 2019 available in the databases of the Department of Informatics of the Brazilian Health System, Information and Management of Primary Care, and the Electronic Citizen Information System. Descriptive analysis of dependent and independent variables and bivariate analysis by Negative Binomial regression were carried out. The mean incidence of congenital syphilis was 38% higher in municipalities with a Human Development Index up to 0.785 (ratio of means [RM] = 1.38; p = 0.049) and 57% higher among populations where less than 50% of primary healthcare services provided a rapid test for syphilis (RM = 1.57; p < 0.001). The ratio between congenital syphilis and syphilis in pregnant women was 29% higher in municipalities with a low household income per capita (RM = 1.29; p < 0.001) and 28% higher in locations where less than 50% of the primary healthcare services provided a rapid test for syphilis (RM = 1.28; p < 0.001). There was no statistical significance of the quality of prenatal care compared to the outcomes. This result underscores the challenges in detecting syphilis infections among pregnant women during prenatal care, consequently increasing the risk of vertical transmission of the disease to the fetus. Traits of inequality in the occurrence of congenital syphilis also draw attention to strategies to reduce health inequities and improve prenatal care.

Sexually transmitted infection (STI) knowledge and perceptions among people in HIV-sero-different partnerships in rural southwestern Uganda

Globally, over one million people acquire curable sexually transmitted infections (STI) each day. Understanding how people think about STIs is key to building culturally appropriate STI prevention and treatment programs. We explored STI knowledge and perceptions in rural, southwestern Uganda to inform future interventions. From August 2020 to December 2020, we conducted individual in-depth interviews among adult men and women (≥18 years) with recent or current personal or partner pregnancy, a history of an STI diagnosis and treatment, and membership in an HIV-sero-different relationship. Interviews explored STI knowledge, perceptions, and barriers and facilitators to engaging in STI care. We used inductive and deductive approaches to generate a codebook guided by the healthcare literacy skills framework in a thematic analysis. Ten men with STI, five of their female partners, eighteen women with STI, and four of their male partners participated in individual in-depth interviews. The median age was 41 (range 27-50) for men and 29 (range 22-40) for women. Sixteen (43%) participants were with HIV. Significant themes include: 1) Participants obtained STI knowledge and information from the community (friends, family members, acquaintances) and medical professionals; 2) While participants knew STIs were transmitted sexually, they also believed transmission occurred via non-sexual mechanisms. 3) Participants associated different connotations and amounts of stigma with each STI, for example, participants reported that syphilis was passed down "genetically" from parent to child. 4) Participants reported uncertainty about whether STIs affected pregnancy outcomes and whether antenatal STI treatment was safe. The complicated nature of STIs has led to understandable confusion in settings without formal sexual healthcare education. Robust counseling and education prior to sexual debut will help allow men and women to understand the signs, symptoms, and treatments necessary for STI cure and to navigate often complicated and overburdened healthcare systems.

Guidelines on Gestational and Congenital Syphilis: insights of health professionals in Bolívar (Colombia)

Objectives

To describe the knowledge, appropriateness and practices regarding the evidence-based “Clinical Practice Guidelines (CPG) for the comprehensive management of gestational syphilis (GS) and congenital syphilis (CS)”.

Material and methods

A descriptive, cross-sectional study including general practitioners, specialists and nurses working at 52 healthcare institutions in the Bolivar Department (Colombia) who provided prenatal control or neonatal care in 2020. Convenience sampling was used. A digital questionnaire was administered to collect sociodemographic information, assessed knowledge, appropriateness and practices in terms of the evidenced-based “Clinical Practice Guidelines (CPG)" mentioned in the objectives. A descriptive analysis followed.

Results

A total of 101 workers were included. There are deficiencies associated with the correct use of the inverse algorithm of diagnosis (48 %) and GS followup (77 %), management of the patient with a history of systemic manifestation allergies (31 %) and treatment of GS (61 %) and CS (10 %). The recommendation of not using the penicillin test in patients with no history of systemic allergies is considered of little benefit (60 %). 23 % of the workers do not use rapid tests and 44 % of the specialists administer syphilis treatment to the sexual partner.

Conclusions

It is important to intensify the training strategies for health personnel with emphasis on nurses and, as a matter of urgency, empower them in syphilis control activities. New and continuous national and regional evaluations of the implementation of these guidelines are needed to assess the indicators associated with the strategy for the elimination of this disease.

Lumbar puncture for neurosyphilis investigation in asymptomatic patients with HIV-syphilis coinfection: a cross-sectional study among infectious disease specialists

BACKGROUND

Syphilis is a major public health issue worldwide. In people living with human immunodeficiency virus (PLHIV), there are higher incidences of both syphilis and neurosyphilis. The criteria for referring PLHIV with syphilis for lumbar puncture is controversial, and the diagnosis of neurosyphilis is challenging.

OBJECTIVE

To describe the knowledge, attitudes, and practices of infectious disease specialists and residents in the context of care for asymptomatic HIV-syphilis coinfection using close-ended questions and case vignettes.

DESIGN AND SETTING

Cross-sectional study conducted in three public health institutions in São Paulo (SP), Brazil.

METHODS

In this cross-sectional study, we invited infectious disease specialists and residents at three academic healthcare institutions to answer a self-completion questionnaire available online or in paper form.

RESULTS

Of 98 participants, only 23.5% provided answers that were in line with the current Brazilian recommendation. Most participants believed that the criteria for lumbar puncture should be extended for people living with HIV with low CD4+ cell counts (52.0%); in addition, participants also believed that late latent syphilis (29.6%) and Venereal Disease Research Laboratory (VDRL) titers ≥ 1:32 (22.4%) should be conditions for lumbar puncture in PLHIV with no neurologic symptoms.

CONCLUSION

This study highlights heterogeneities in the clinical management of HIV-syphilis coinfection. Most infectious disease specialists still consider syphilis stage, VDRL titers and CD4+ cell counts as important parameters when deciding which patients need lumbar puncture for investigating neurosyphilis.

Temporal trend of congenital syphilis in the most populous municipality of metropolitan region II of Rio de Janeiro state

OBJECTIVE

This study aimed to explore the temporal trend in congenital syphilis, according to sociodemographic and prenatal care in the city of São Gonçalo - Rio de Janeiro, from 2007 to 2018.

METHODS

Ecological time series study, with data from SINAN (Information System for Notifiable Diseases) and SINASC (Information System on Live Births databases). We calculated annual incidence (per 1,000 live births) according to sociodemographic and prenatal variables. For the same variables, we calculated trends by logarithmic regression (Joinpoint Regression), estimating the annual percentage change.

RESULTS

A total of 2,420 cases were reported from 2007 to 2018, with an increasing trend: 64.9% per year (2010-2013) and 24.9% (2013-2018). In 2018, the highest rates were in adolescents (90.6/1,000 live births), black women (87.6/1,000 live births), low-educated women (122.8/1,000 live births), and those without prenatal care (677.4/1,000 live births). The annual percentage change of these categories was, respectively, 37.3% (2010-2018), 33.5% (2012-2018), 39.9% (2014-2018), and 85.0% (2011-2015), but all categories showed a crescent trend.

CONCLUSIONS

We identified high congenital syphilis incidences and crescent trends, especially in more vulnerable groups, pointing to social and healthcare inequalities. Prenatal care needs to be more comprehensive and qualified, primarily for young, low-educated, and black women.

Syphilis response policies and their assessments: A scoping review

Syphilis is one of the most common sexually transmitted infections (STIs) worldwide and has shown a rising trend in recent years, according to a report published by the World Health Organization (WHO) in 2021. Given this problem, the present study aims to develop a scoping review of what has been done in the world after the publication of the global strategy for the elimination of STIs, with a specific focus on syphilis. Thus, we searched for papers on health policies in response to syphilis in Pubmed, Scopus, ScienceDirect, and EBSCO by CINAHL, as well as in official documents from international health organizations. The period from January 1, 2016, to August 14, 2022 was considered. Our search returned 880 papers addressing "Syphilis," "Health Policy," and "Health Policies" combined. Twenty-three papers fulfilled the inclusion and exclusion criteria according to two research questions set out for this scoping review. Our findings suggest that Brazil and Peru presented the greatest adequacy of the strategies provided by WHO in 2016 and the Pan American Health Organization (PAHO) in 2017, aiming tothe goals set out in the UN's 2030 Agenda for sustainable development. Among the studies found, six countries (Cuba, Thailand, Belarus, Armenia, Moldova, and Puerto Rico) reported the elimination of mother-to-child transmission (MTCT) of syphilis, but the most recent data are from 2016. Furthermore, it is essential to mention that no country has been found that has presented a comprehensive response to syphilis, noting the control or elimination of the disease in all key populations. Thus, it is necessary to constantly monitor national policies based on in-depth studies on the quality of the response, the challenges, and the national, regional, and global perspectives for the control of the disease until 2030, the year in which the SDGs will be reviewed.

New screening approach to detecting congenital syphilis in China: a retrospective cohort study

BACKGROUND

Diagnosis of congenital syphilis (CS) is not straightforward and can be challenging. This study aimed to evaluate the validity of an algorithm using timing of maternal antisyphilis treatment and titres of non-treponemal antibody as predictors of CS.

METHODS

Confirmed CS cases and those where CS was excluded were obtained from the Guangzhou Prevention of Mother-to-Child Transmission of syphilis programme between 2011 and 2019. We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) using receiver operating characteristics (ROC) in two situations: (1) receiving antisyphilis treatment or no-treatment during pregnancy and (2) initiating treatment before 28 gestational weeks (GWs), initiating after 28 GWs or receiving no treatment for syphilis seropositive women.

RESULTS

Among 1558 syphilis-exposed children, 39 had confirmed CS. Area under the curve, sensitivity and specificity of maternal non-treponemal titres before treatment and treatment during pregnancy were 0.80, 76.9%, 78.7% and 0.79, 69.2%, 88.7%, respectively, for children with CS. For the algorithm, ROC results showed that PPV and NPV for predicting CS were 37.3% and 96.4% (non-treponemal titres cut-off value 1:8 and no antisyphilis treatment), 9.4% and 100% (non-treponemal titres cut-off value 1:16 and treatment after 28 GWs), 4.2% and 99.5% (non-treponemal titres cut-off value 1:32 and treatment before 28 GWs), respectively.

CONCLUSIONS

An algorithm using maternal non-treponemal titres and timing of treatment during pregnancy could be an effective strategy to diagnose or rule out CS, especially when the rate of loss to follow-up is high or there are no straightforward diagnostic tools.

Congenital syphilis in East Baton Rouge parish, Louisiana: providers' and women's perspectives

Background

Congenital syphilis is completely preventable through screening and treatment, but rates have been rising in the United States. Certain areas are at particularly high risk. We aimed to assess attitudes, knowledge, and barriers around effective prevention of congenital syphilis among health care providers and community women potentially at risk.

Methods

Two parallel studies were conducted: in-depth interviews with health care providers and focus groups with community women in the area of Baton Rouge, Louisiana. Each group was questioned about their experience in providing or seeking prenatal care, knowledge and attitudes about congenital syphilis, sources of information on testing and treatment, perceptions of risk, standards of and barriers to treatment. Results were transcribed into QSR NVivo V10, codes developed, and common themes identified and organized.

Results

Providers identified delays in testing and care, lack of follow-through with partner testing, and need for community connection for prevention, as major contributors to higher rates of congenital syphilis. Women identified difficulties in accessing Medicaid contributing to delayed start of prenatal care, lack of transportation for prenatal care, and lack of knowledge about testing and prevention for congenital syphilis.

Conclusions

Providers and community members were in broad agreement about factors contributing to higher rates of congenital syphilis, although some aspects were emphasized more by one group or another. Evidence-based interventions, likely at multiple levels, need to be tested and implemented to eliminate congenital syphilis.

[Inequalities in congenital syphilis trends in the city of Niterói, Brazil, 2007-2016Desigualdades en la tendencia de sífilis congénita en la ciudad de Niterói, Brasil, 2007-2016]

Objetivo.

Descrever a distribuição temporal e as características epidemiológicas da sífilis congênita (SC) em Niterói, Sudeste do Brasil, de 2007 a 2016.

Métodos.

Este estudo descritivo de série temporal da incidência de SC utilizou os dados do Sistema de Informação de Agravos de Notificação (SINAN) e do Sistema de Informações sobre Nascidos Vivos (SINASC). A amostra incluiu todos os casos notificados. Além disso, foi realizado um relacionamento probabilístico entre SINAN e SINASC para recuperar informações ignoradas. A série temporal foi estimada por regressão logarítmica, de acordo com variáveis sociodemográficas e de pré-natal.

Resultados.

Identificaram-se 754 casos de SC no período estudado (incidência média de 11,9 casos/1 000 nascidos vivos). A incidência foi mais elevada em jovens (10 a 19 anos; 20 a 24 anos), participantes de cor preta e naquelas com baixa escolaridade e sem pré-natal. Do total de mulheres, apenas 57,6% obtiveram o diagnóstico de sífilis durante o pré-natal. O tratamento foi inadequado em 87,7% das mulheres. Apenas 12,2% dos parceiros foram tratados. Houve tendência crescente do agravo (16%/ano), que atingiu 23,2 casos/1 000 nascidos vivos em 2016. O crescimento foi mais acentuado em adolescentes do sexo feminino (25,2%/ano), raça/cor parda (16,8%/ano), indivíduos com baixa escolaridade (57,1%/ano) e mulheres que realizaram pré-natal (17,3%/ano); e, no período de 2012 a 2016, em mulheres com informação ignorada para a cor da pele.

Conclusões.

As iniquidades sociais se destacaram na ocorrência de SC, com incidência crescente em jovens. É necessária a capacitação dos profissionais de saúde para o manejo da sífilis gestacional e uma atuação efetiva das políticas públicas sobre os determinantes sociais da sífilis.

Viral, bacterial, and fungal infections of the oral mucosa: Types, incidence, predisposing factors, diagnostic algorithms, and management

For millions of years, microbiota residing within us, including those in the oral cavity, coexisted in a harmonious symbiotic fashion that provided a quintessential foundation for human health. It is now clear that disruption of such a healthy relationship leading to microbial dysbiosis causes a wide array of infections, ranging from localized, mild, superficial infections to deep, disseminated life-threatening diseases. With recent advances in research, diagnostics, and improved surveillance we are witnessing an array of emerging and re-emerging oral infections and orofacial manifestations of systemic infections. Orofacial infections may cause significant discomfort to the patients and unnecessary economic burden. Thus, the early recognition of such infections is paramount for holistic patient management, and oral clinicians have a critical role in recognizing, diagnosing, managing, and preventing either new or old orofacial infections. This paper aims to provide an update on current understanding of well-established and emerging viral, bacterial, and fungal infections manifesting in the human oral cavity.

What is the supporting role of health care providers from the perspective of patients with renal allograft rejection? A qualitative study

Coping with the new conditions for patients with renal allograft rejection is a complex phenomenon influenced by a number of factors. It appears that the supportive role of health care providers in many aspects is 1 of the most important factors in patient satisfaction, increased quality of life, and application of proper coping mechanisms. This study explored the perceptions of patients with renal allograft rejection about the supportive role of health care providers. This study was conducted with a qualitative research approach and content analysis. Participants were 19 patients with renal allograft rejection in teaching hospitals in southeastern Iran who were selected by purposive sampling. Data were collected through semistructured interviews and analyzed by qualitative content analysis. During content analysis, 2 categories emerged: empathy and emotional support and educational counseling. These themes reflect the nature of patient perceptions of the supportive role of health care providers. The findings suggest that the supportive role of health care providers plays an important role in the promoting a feeling of comfort, reliability, and security in patients with renal allograft rejection and improves their coping mechanisms. These findings give health care providers greater motivation to provide comprehensive care from knowledge of their supportive role.
