Treponema pallidum PCR with blood and cerebrospinal fluid of newborns exposed and not exposed to syphilis during pregnancy.

INTRODUCTION: Congenital syphilis (CS) has severe adverse outcomes, including abortion and death. Diagnosis of CS in asymptomatic newborns remains difficult. This study aims to evaluate an in-house polymerase chain reaction (PCR) on cerebrospinal fluid (CSF) and blood samples (BS) to identify T. pallidum DNA in newborns. METHODOLOGY: We performed an exploratory cross-sectional study that included newborns exposed to syphilis during pregnancy (SEG) and non-exposed (SNEG) newborns, between 2019 and 2020. In-house conventional PCR for T. pallidum targeting the tpp47 gene was used to analyze CSFS and dried blood spots. RESULTS: BS was obtained from 54 newborns (33 SEG/21 SNEG) and CSF from 55 newborns (33 SEG/22 SNEG). Twenty-five (71.4%) SEG newborns had reactive BS rapid plasmatic reagins (RPR), and all of them had RPR titers less than or equal to the corresponding maternal titers. All RPR CSF tests were negative. PCR for T. pallidum DNA was positive in 19/33 (57.6%) BS, and in 22/33 CSF. The only SEG newborn with clinical signs of early CS had a positive CSF PCR and a negative BS PCR. Conversely, among SNEG newborns, PCR was positive in 2/21 BS and 5/22 (22.7%) CSF. CONCLUSIONS: T. pallidum DNA was identified using our PCR tests. The exposed group did not present abnormalities that would indicate CS. This prevented conclusions regarding sensitivity and specificity. Dried spot permitted bedside collection, easy transportation, and storage. Further research is needed to evaluate and improve the accuracy of CS low-cost PCR tests, especially for limited resource settings.

Development and validation of an individualised nomogram to predict mother-to-child transmission in pregnant women with syphilis in China: a retrospective cohort study.

OBJECTIVES: The elimination of mother-to-child transmission (MTCT) of syphilis has been set as a public health priority. However, an instrument to predict the MTCT of syphilis is not available. We aimed to develop and validate an intuitive nomogram to predict the individualised risk of MTCT in pregnant women with syphilis in China. DESIGN: Retrospective cohort study. SETTING: Data was acquired from the National Information System of Prevention of MTCT of Syphilis in Guangdong province between 2011 and 2020. PARTICIPANTS: A total of 13 860 pregnant women with syphilis and their infants were included and randomised 7:3 into the derivation cohort (n=9702) and validation cohort (n=4158). PRIMARY OUTCOME MEASURES: Congenital syphilis. RESULTS: Among 13 860 pregnant women with syphilis and their infants included, 1370 infants were diagnosed with congenital syphilis. Least absolute shrinkage and selection operator regression and multivariable logistic regression showed that age, ethnicity, registered residence, marital status, number of pregnancies, transmission route, the timing of syphilis diagnosis, stage of syphilis, time from first antenatal care to syphilis diagnosis and toluidine red unheated serum test titre were predictors of MTCT of syphilis. A nomogram was developed based on the predictors, which demonstrated good calibration and discrimination with an area under the curve of the receiver operating characteristic of 0.741 (95% CI: 0.728 to 0.755) and 0.731 (95% CI: 0.710 to 0.752) for the derivation and validation cohorts, respectively. The net benefit of the predictive models was positive, demonstrating a significant potential for clinical decision-making. We have also developed a web calculator based on this prediction model. CONCLUSIONS: Our nomogram exhibited good performance in predicting individualised risk for MTCT of syphilis, which may help guide early and personalised prevention for MTCT of syphilis.

Associated factors, incidence, and management of gestational and congenital syphilis in a Brazilian state capital: a cross-sectional study.

Maternal and child health remains an enduring global challenge, having occupied a prominent position on international agendas since the dawn of the 21st century. During pregnancy, syphilis emerges as the second most prevalent cause of stillbirth on a global scale, potentially leading to a range of adverse outcomes. This study aimed to describe the clinical and epidemiological profile of cases of gestational and congenital syphilis and the hospital care provided for newborns in Campo Grande municipality, Mato Grosso do Sul State, Brazil, from 2013 to 2018. This is a cross-sectional study based on data from Brazilian Notifiable Diseases Surveillance System (SINAN) and hospital medical records. Chi-square or Fisher's exact test and logistic regression analysis were used to assess the associations and relationships between the child's clinical outcome at birth and the mother's clinical-obstetric and epidemiological characteristics. Cumulative detection rate of gestational syphilis was 174.3 cases per 1,000 live births and cumulative incidence of congenital syphilis was 47.7 cases per 1,000 live births. Alcoholism, prenatal care, number of prenatal visits, maternal treatment regimen, and timing of maternal diagnosis were associated with child's clinical outcome at birth and considered in the regression model. Prenatal visits showed a protective effect against the signs and symptoms of congenital syphilis (odds ratio = 0.37; 95% confidence interval = 0.17-0.77). Medical assistance was considered inadequate in 62.3% of cases. Prenatal consultations should be encouraged among pregnant women. There is a need for better education of health personnel on the treatment and diagnosis of syphilis.

Factors influencing the positivity of diagnostic tests for congenital syphilis.

OBJECTIVE: The objective of this study was to analyze the factors that influence the positivity of treponemal and non-treponemal tests in cases of congenital syphilis. METHODS: This cross-sectional and correlational study was carried out from the analysis of the database of Disease and Notification Information System (SINAN, in Portuguese) using the data obtained through the Epidemiological Surveillance Group 29, with 639 notifications of congenital syphilis between 2007 and 2018. The data were analyzed by a descriptive and inferential analysis from logistic regression with a significance level of 5% (p≤0.05). RESULTS: The positivity of the treponemal test was higher by 4.5 times in infants living in rural areas and 19.6 times among those whose mothers obtained the diagnosis of syphilis after birth. The treponemal test showed positivity 3.2 times higher for the variable "having been diagnosed between 2007 and 2015" and 5.5 times higher for the variable "having been diagnosed with maternal syphilis in the postpartum period." CONCLUSION: This study shows that testing during prenatal care is essential for early diagnosis and prevention of syphilis complications.

The resurgence of syphilis in Australia.

BACKGROUND: Syphilis infections have been increasing in Australia over the past decade. This phenomenon has been associated with a re-emergence of congenital syphilis. OBJECTIVE: The aim of this article is to describe recent epidemiological trends of syphilis infection in Australia, including demographics in which infection rates are rising, such as women of reproductive age. This article also provides an overview of the clinical course and the principles of management for syphilis. DISCUSSION: Considered by some as a disease of bygone eras, the resurgence of syphilis in Australia requires clinicians to be alert to this infection once again. Increased testing, prompt management and thorough contact tracing are all required to reverse this trend. Congenital syphilis is a potentially devastating yet preventable consequence of rising infections among women of reproductive age. Universal syphilis screening is recommended for all pregnant women at the initial antenatal visit and is now also recommended in the third trimester in several Australian jurisdictions.

Provider-Reported Barriers in Sexual Health Care Services for Women With Upstream Barriers: The Case of Syphilis and Congenital Syphilis in Southern Colorado, 2022.

BACKGROUND: Syphilis and congenital syphilis rates have increased sharply in Colorado in the past 5 years. Congenital syphilis is passed during pregnancy in utero and can cause lifelong physical, developmental, and neurologic problems for the child, or can lead to miscarriage, stillbirth, or early infant death. Congenital syphilis is easily prevented if the mother receives timely testing, treatment, and prenatal care. Providers can play a key role in preventing congenital syphilis for women with social vulnerabilities, who have a higher likelihood of syphilis and/or congenital syphilis infection. METHODS: We surveyed 23 and interviewed 4 health care providers in southern Colorado in 2022 to record their experiences in providing sexual health care services. We asked providers with direct care experience about perceived barriers in effectively treating syphilis. RESULTS: The most significant barriers reported in the survey were the cost of treatment (26%) and the loss to follow-up (22%). Interviews revealed further challenges, including discretionary testing procedures, delays in screening results, treatment referral issues, and stigma around substance use and sexual activity. CONCLUSIONS: Elevated syphilis and congenital syphilis rates pose significant public health challenges. Coordinated interventions are necessary to effectively reduce the transmission of syphilis and congenital syphilis among women with upstream barriers. Potential care solutions include expanding rapid, point-of care testing and treatment options, supporting bicillin delivery or web-based inventory systems, offering anti-stigma training for providers, offering mental and behavioral health resources at providers' clinics, and expanding partnerships with syringe access programs.

Trends and Characteristics in Maternal Syphilis Rates During Pregnancy: United States, 2016-2022.

After reaching historic lows in 2000 and 2001, rates of primary and secondary syphilis in the overall U.S. population have increased nearly every year through 2022 (1). For 2017-2022, rates of syphilis for women of reproductive age and congenital syphilis (a disease that occurs when a mother with syphilis passes the infection on to her baby during pregnancy) increased by more than 250% (1,2). Congenital syphilis can cause adverse pregnancy outcomes such as fetal and neonatal death, low birthweight, preterm birth, and brain and nerve disorders (2). This report presents trends in maternal syphilis rates in women giving birth in the United States for 2016-2022 by selected maternal demographic and health factors.

Update on syphilis in pregnancy: marrying basic science advances and clinical perseverance to solve an ancient public health problem.

PURPOSE OF REVIEW: While the clinical disease of syphilis, its consequences in pregnancy, and its sensitivity to penicillin treatment have remained relatively unchanged for a century or more, new technologies and basic discoveries in syphilis research have translated into tangible advances in clinical diagnosis, treatment, and prevention. The purpose of this review is to help the reader understand some of the recent relevant scientific publications on syphilis and its causative organism in a clinical obstetric context. RECENT FINDINGS: Rates of adult and congenital syphilis have risen dramatically in the last decade despite public health efforts. Penicillin shortages and lack of screening or adequate treatment have all contributed to global disease burden. Advances in genomic and microbiological characterization of this spirochete have led to new developments in serologic and molecular diagnosis as well as evaluation of potential vaccine candidates. Until a syphilis vaccine is available, substance use disorders and lack of screening in pregnancy are associated with increased congenital syphilis, and these challenges will require novel solutions to fully address this public health crisis. SUMMARY: Addressing the burden of congenital syphilis demands that obstetricians stay well informed of new tools and resources for diagnosis, treatment, and prevention of syphilis now and in the future.

Congenital syphilis: the re-emergence of a forgotten disease.

A preterm newborn presented at birth with generalised oedema, disseminated bullous and desquamative exanthema with palmoplantar involvement and hepatomegaly, admitted to the neonatal intensive care unit with severe multisystemic disease, haemodynamic instability and respiratory distress. The mother had a history of treated latent syphilis before pregnancy. Venereal Disease Research Laboratory screening was negative in the first trimester, titre 1:2 in second trimester and 1:32 in the third trimester, a result only available to the medical team at birth. The mother's rapid plasma reagin (RPR) titre was 1:64 at birth. The newbon's RPR titre was 1:256, confirming the diagnosis of early congenital syphilis. The newborn was treated with aqueous penicillin G, with clinical and laboratorial progressive recovery. Congenital syphilis is a preventable disease, but despite prenatal screening programmes, it remains a significant public health issue worldwide with high morbidity and mortality.

Congenital bullous syphilis in a newborn: A novel approach to diagnosis using immunohistochemical staining on a blister roof.

We describe a rare presentation of congenital bullous syphilis in a premature neonate born with extensive skin desquamation. The newborn was noted to have diffuse erythema with widespread, superficial skin desquamation in addition to plantar bullae and erosions, and an absence of mucosal involvement. Immunohistochemical syphilis diagnostic staining was performed on a blister roof, highlighting a novel diagnostic approach for congenital bullous syphilis.

Clinical-Demographic and Laboratory Profile of the Mother-Child Binomial With Syphilis in a Tertiary-Level Hospital in Mexico.

BACKGROUND: Congenital syphilis (CS) remains a major public health problem, and its incidence is increasing worldwide. METHODS: Retrospective, observational, and descriptive study of cases with CS and their mothers at a tertiary-level hospital in Mexico from 2017 to 2022. Medical records of patients with CS and a structured collection of epidemiological, clinical, and laboratory data were analyzed and classified in the Centers for Disease Control scenarios as confirmed, probable, less probable, or unlikely. RESULTS: One hundred eighty cases were diagnosed with a compatible definition of congenital syphilis, and we identified 43 (21.21%) confirmed proven. Among those proven cases, 15.6% had hematological, 13.3% skin, 12.2% liver, 6.7% pulmonary, 6.6% neurological, 5.8% eye, 5.6% bone, and 0.6% hearing involvements. According to the clinical stages of maternal syphilis, 119 (66.1%) were in the late latent phase, 49 (27.2%) in the early latent phase, 7 (3.9%) in the secondary stage, and 5 (2.8%) in the primary stage. Mothers with tertiary syphilis were not detected. CONCLUSION: Regardless of negative antenatal screening, health care workers should consider the diagnosis of congenital syphilis. Infants are still undiagnosed at birth, and only a tiny percentage exhibits symptoms. The wide range of clinical manifestations of this preventable infection can be misdiagnosed for various other diseases, causing diagnostic delays that can have serious consequences.

The Congenital Syphilis Prevention Cascade: Reimagining a Missed Prevention Opportunities Framework for Effective Intervention.

ABSTRACT: Congenital syphilis (CS) rates have risen in the United States since 2013. Prevention of CS requires testing and treatment of pregnant and pregnancy-capable persons at high risk for syphilis. We developed a CS Prevention Cascade to assess how effectively testing and treatment interventions reached pregnant persons with a CS outcome.

Pemphigus syphiliticus with Jarisch-Herxheimer reaction in a newborn.

Congenital syphilis is a serious, disabling, and life-threatening infection that is transmitted transplacentally from mother to fetus. Early diagnosis is often difficult because affected infants are usually asymptomatic at birth and clinical findings are often subtle and nonspecific. Pemphigus syphiliticus is an early presentation of congenital syphilis which is characterized by fluid-filled vesicles and bullae which appear mostly on the extremities and tend to rapidly desquamate and erode. Awareness of the clinicians to this early cutaneous manifestation and possible treatment reaction will allow for prompt diagnosis and adequate treatment of syphilis-infected patients.

Resurgence of congenital syphilis: new strategies against an old foe.

Congenital syphilis is a major global cause of fetal loss, stillbirth, neonatal death, and congenital infection. In 2020, the global rate of congenital syphilis was 425 cases per 100 000 livebirths-substantially higher than WHO's elimination target of 50 cases per 100 000 livebirths. Case rates are rising in many high-income countries, but remain low compared with those in low-income and middle-income settings. This Review aims to summarise the current epidemiology and knowledge on transmission and treatment of syphilis in pregnancy, and proposes measures to reduce the rising incidence seen worldwide. We also describe emerging diagnostic and treatment tools to prevent vertical transmission and improve management of congenital syphilis. Finally, we outline a programme of public health priorities, which include research, clinical, and preventive strategies.
