RESUMO
In 2007, the World Health Organization (WHO) launched a global health initiative for the elimination of mother-to-child transmission (MTCT) of syphilis. This condition is highly preventable through antenatal identification of syphilis infection and treatment with penicillin during pregnancy. This review summarizes the global status of MTCT of syphilis and concludes that this condition remains a significant issue worldwide. There are large variations in case rates by region, with the highest numbers of cases in the African and Eastern Mediterranean regions, where there are also the least data available. There are also pockets of high-incidence areas within the other regions. Although the general trend is of decreasing rates over time, there are concerning indications of consistently increasing congenital syphilis cases in some areas, particularly in areas which have previously had very low case numbers. A concerted effort will be required to achieve the 2007 WHO goal of worldwide elimination of MTCT of syphilis in the near future.

High incidences of congenital syphilis have been reported in areas along the Pacific coast of Colombia. In this retrospective study, conducted during 2018-2022 at a public hospital in Buenaventura, Colombia, we analyzed data from 3,378 pregnant women. The opportunity to prevent congenital syphilis was missed in 53.1% of mothers because of the lack of syphilis screening. Characteristics of higher maternal social vulnerability and late access to prenatal care decreased the probability of having >1 syphilis screening test, thereby increasing the probability of having newborns with congenital syphilis. In addition, the opportunity to prevent congenital syphilis was missed in 41.5% of patients with syphilis because of the lack of treatment, which also increased the probability of having newborns with congenital syphilis. We demonstrate the urgent need to improve screening and treatment capabilities for maternal syphilis, particularly among pregnant women who are more socially vulnerable.

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.

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.

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.

OBJECTIVES: To estimate notification rates for infectious syphilis in women of reproductive age and congenital syphilis in Australia. STUDY DESIGN: Retrospective cohort study; analysis of national infectious syphilis and enhanced congenital syphilis surveillance data. SETTING, PARTICIPANTS: Women aged 15-44 years diagnosed with infectious syphilis, and babies with congenital syphilis, Australia, 2011-2021. MAIN OUTCOME MEASURES: Numbers and rates of infectious syphilis notifications, by Indigenous status and age group; numbers and rates of congenital syphilis, by Indigenous status of the infant; antenatal care history for mothers of infants born with congenital syphilis. RESULTS: During 2011-2021, 5011 cases of infectious syphilis in women aged 15-44 years were notified. The notification rate for Aboriginal and Torres Strait Islander women rose from 56 (95% confidence interval [CI], 45-65) cases per 100 000 in 2011 to 227 (95% CI, 206-248) cases per 100 000 population in 2021; for non-Indigenous women, it rose from 1.1 (95% CI, 0.8-1.4) to 9.2 (95% CI, 8.4-10.1) cases per 100 000 population. The notification rate was higher for Aboriginal and Torres Strait Islander women than for non-Indigenous women (incidence rate ratio [IRR], 23.1; 95% CI, 19.7-27.1), lower for 15-24- (IRR, 0.7; 95% CI, 0.6-0.9) and 35-44-year-old women (IRR, 0.6; 95% CI, 0.5-0.7) than for 25-34-year-old women, and higher in remote regions than in major cities (IRR, 2.7; 95% CI, 2.2-3.8). During 2011-2021, 74 cases of congenital syphilis were notified, the annual number increasing from six in 2011 to a peak of 17 in 2020; the rate was consistently higher among Aboriginal and Torres Strait Islander infants than among non-Indigenous infants (2021: 38.3 v 2.1 per 100 000 live births). The mothers of 32 infants with congenital syphilis (43%) had not received antenatal care. CONCLUSIONS: The number of infectious syphilis notifications for women of reproductive age increased in Australia during 2011-2021, as did the number of cases of congenital syphilis. To avert congenital syphilis, antenatal screening of pregnant women, followed by prompt treatment for infectious syphilis when diagnosed, needs to be improved.

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.

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.

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.

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.

Infectious and Congenital Syphilis rates continue to rise globally. Current recommendations for syphilis screening and treatment may be insufficient, and there is a pressing need for improved programs and services to address the increase in cases. A scoping review was conducted to examine approaches to maternal syphilis screening and treatment. Theoretical underpinnings and the key characteristics of these interventions were studied to identify gaps in the existing literature to guide future research. Developing a modified version of the socio-ecological model to guide data analysis, we included 33 academic studies spanning 31 years, covering a range of interventions, programs, and policies globally. We highlight key facets of interventions aligning with the five levels of the modified model that include: individual, interpersonal, institutional, community and policy. In this review, we provide valuable insights into the characteristics and principles of maternal syphilis screening and treatment interventions.
Even with advances in care, there remain many similarities in interventions for the improved treatment and screening of maternal syphilis over the past 30 years.There is a need for meaningful research that engages community members in study and intervention development and considers the social determinants of health in the context of maternal syphilis care.Examining interventions in relation to the socio-ecological model may help guide policymakers, researchers, and clinicians in intervention development.

Nearly half of all sexually transmitted infections occur in adolescents and young adults. Among them, syphilis infections are on the rise in the United States. Sexually active adolescents, especially those who do not use condoms consistently or are men who have sex with men, are at particular risk for syphilis infection. With the rise in acquired syphilis infections, the incidence of congenital syphilis has also increased. Syphilis can have a variety of presentations based on infectious stage and central nervous system involvement. Careful physical examination and history can elicit the diagnosis. Screening with a nontreponemal test followed by treponemal testing can confirm the diagnosis, and staging is determined clinically. Testing for all sexually transmitted infections should be pursued because coinfections are common. Penicillin is the first-line treatment for syphilis, and duration of therapy depends on the presence of neurologic symptoms; all infants with possible congenital syphilis should receive treatment. Posttreatment monitoring is essential to confirm successful eradication of syphilis. All sexually active, at-risk patients, including pregnant persons, should be screened for syphilis, and those diagnosed as having syphilis should be counseled on disclosure to partners. Although not often found in a pediatric population, with the increasing incidence of syphilis infections in the United States, pediatric providers should have a low threshold for syphilis screening in adolescents and a high index of suspicion for congenital syphilis in infants.

We conducted a nested case-control study within a cohort with the aim of studying the association between illicit drug use and congenital syphilis (CS). Cases were diagnosed based on treponemal and non-treponemal tests conducted both in the mother and the newborn (NB). Multivariate analysis with logistic regression was performed. A total of 6171 births with a mean gestational age of 37.8 weeks were recorded and 62 CS events were diagnosed (incidence 10.5 events/1000 NB). Associated maternal factors were illicit drug use (OR 14.08, 95% CI 1.19-166.6), <5 prenatal visits (OR 2.9, 95% CI 1.12-7.53), more than two sexual partners (OR 3.76, 95% CI 1.62-8.71) and professional education level (OR 0.06, 95% CI 0.005-0.85). Among the mothers of the cases presented, the prevalence of illicit drug use was 22.6% and the most frequent drugs were methamphetamines and cannabis.

BACKGROUND: The WHO presented the initiative: "Global elimination of congenital syphilis (CS): rationale and strategies for action". It establishes that CS is a preventable disease that can be eliminated. OBJECTIVE: To estimate the proportion of missed opportunities for prevention (MOP) of (CS). MATERIAL AND METHODS: Cross-sectional study. We studied women with children with confirmed diagnosis of CS (NOM-039-SSA2-2002) in the Mexican Social Security Institute in Jalisco from 01/01/2016 to 08/01/2022. The clinical records of the mother, the newborn and the epidemiological study (ES) were reviewed. Each case was classified into one of the MOP categories. RESULTS: 52 cases were reported: 46.2 % (n = 24) were ruled out, 34.6 % (n = 18) confirmed, 15.4 % (n = 8) unknown and 3.8 % (n = 2) probable cases. The HIV test was performed in 61.1 % (n = 11) and syphilis in 72.2 % (n = 13) of the mothers. The MOP in 27.8 % (n = 5) was inadequate treatment or omission of maternal treatment despite a timely diagnosis of syphilis. Treatment was inadequate in 63.6 % (n = 7) of the women who received it. CONCLUSION: The classification of MOP identifies gaps in CS prevention and can guide stakeholders, policy makers and public health prevention programs to reduce the incidence of CS.
ANTECEDENTES: La Organización Mundial de la Salud estableció que la sífilis congénita es una enfermedad prevenible que puede eliminarse. OBJETIVO: Estimar la proporción de oportunidades perdidas en la prevención (OPP) de la sífilis congénita. MATERIAL Y MÉTODOS: Estudio transversal descriptivo. Se eligieron mujeres en cuyos hijos recién nacidos se identificó sífilis congénita entre 2016 y 2022. Se revisaron los expedientes clínicos de la madre, el recién nacido y el estudio epidemiológico. Cada caso se clasificó en una de las categorías de las OPP. RESULTADOS: Se notificaron 52 casos: 46.2 % (n = 24) fue descartado, 34.6 % (n = 18) confirmado, 15.4 % (n = 8) desconocido y 3.8 % (n = 2) probable. Las pruebas para identificar infección por VIH y sífilis se realizaron en 61.1 % (n = 11) y 72.2 % de las madres (n = 13). La OPP en 27.8 % (n = 5) consistió en el tratamiento inadecuado u omisión de tratamiento materno a pesar de diagnóstico oportuno de la sífilis. De quienes recibieron tratamiento, en 63.6 % fue inadecuado (n = 7). CONCLUSIÓN: La clasificación de OPP de sífilis congénita permite identificar brechas en la prevención y dirigir intervenciones de salud pública hacia las principales causas para reducir la incidencia.

BACKGROUND: The purpose of this study was to estimate the health impact of syphilis in the United States in terms of the number of quality-adjusted life years (QALYs) lost attributable to infections in 2018. METHODS: We developed a Markov model that simulates the natural history and management of syphilis. The model was parameterized by sex and sexual orientation (women who have sex with men, men who have sex with women [MSW], and men who have sex with men [MSM]), and by age at primary infection. We developed a separate decision tree model to quantify health losses due to congenital syphilis. We estimated the average lifetime number of QALYs lost per infection, and the total expected lifetime number of QALYs lost due to syphilis acquired in 2018. RESULTS: We estimated the average number of discounted lifetime QALYs lost per infection as 0.09 (95% uncertainty interval [UI] .03-.19). The total expected number of QALYs lost due to syphilis acquired in 2018 was 13 349 (5071-31 360). Although per-case loss was the lowest among MSM (0.06), MSM accounted for 47.7% of the overall burden. For each case of congenital syphilis, we estimated 1.79 (1.43-2.16) and 0.06 (.01-.14) QALYs lost in the child and the mother, respectively. We projected 2332 (1871-28 250) and 79 (17-177) QALYs lost for children and mothers, respectively, due to congenital syphilis in 2018. CONCLUSIONS: Syphilis causes substantial health losses in adults and children. Quantifying these health losses in terms of QALYs can inform cost-effectiveness analyses and can facilitate comparisons of the burden of syphilis to that of other diseases.

BACKGROUND: Congenital syphilis (CS) is a major and avoidable cause of neonatal death worldwide. In this study, we aimed to estimate excess all-cause mortality in children under 5 years with CS compared to those without CS. METHODS AND FINDINGS: In this population-based cohort study, we used linked, routinely collected data from Brazil from January 2011 to December 2017. Cox survival models were adjusted for maternal region of residence, maternal age, education, material status, self-declared race and newborn sex, and year of birth and stratified according to maternal treatment status, non-treponemal titers and presence of signs and symptoms at birth. Over 7 years, a total of 20 057 013 live-born children followed up (through linkage) to 5 years of age, 93 525 were registered with CS, and 2 476 died. The all-cause mortality rate in the CS group was 7·84/1 000 person-years compared with 2·92/1 000 person-years in children without CS, crude hazard ratio (HR) = 2·41 (95% CI 2·31 to 2·50). In the fully adjusted model, the highest under-five mortality risk was observed among children with CS from untreated mothers HR = 2·82 (95% CI 2·63 to 3·02), infants with non-treponemal titer higher than 1:64 HR = 8·87 (95% CI 7·70 to 10·22), and children with signs and symptoms at birth HR = 7·10 (95% CI 6·60 to 7·63). Among children registered with CS, CS was recorded as the underlying cause of death in 33% (495/1 496) of neonatal, 11% (85/770) of postneonatal, and 2·9% (6/210) of children 1 year of age. The main limitations of this study were the use of a secondary database without additional clinical information and the potential misclassification of exposure status. CONCLUSIONS: This study showed an increased mortality risk among children with CS that goes beyond the first year of life. It also reinforces the importance of maternal treatment that infant non-treponemal titers and the presence of signs and symptoms of CS at birth are strongly associated with subsequent mortality. TRIAL REGISTRATION: Observational study.

OBJECTIVES: To document the case-fatality rate (CFR) of congenital syphilis diagnosed by molecular tools and rabbit infectivity testing (RIT) of clinical specimens in addition to standard evaluation and to compare that with the CFR using the Centers for Disease Control and Prevention (CDC) surveillance case definition. STUDY DESIGN: Prospective, single site, cohort study of all cases of syphilis among mothers and their infants from 1984 to 2002. The diagnosis of congenital syphilis was determined using IgM immunoblotting, polymerase chain reaction, and RIT of fetal or infant specimens in addition to clinical, laboratory, and radiographic criteria. Data were retrospectively reviewed to ascertain fetal and neonatal mortality. RESULTS: During the 18-year study, there were 191 cases of congenital syphilis confirmed by abnormalities on clinical, laboratory, or radiographic evaluation and/or positive serum IgM immunoblot, blood polymerase chain reaction, or blood/cerebrospinal fluid RIT. Of the 191 cases, 59 died for a CFR of 31%. Of the 59 deaths, 53 (90%) were stillborn and 6 (10%) died in the neonatal period. The majority (74%, 39/53) of stillbirths occurred in the third trimester. The CDC surveillance case definition correctly identified all infants with congenital syphilis, but the CDC CFR was 10% which underestimated the CFR by more than 300%. CONCLUSIONS: Our findings corroborate the high sensitivity of the CDC surveillance definition for congenital syphilis but highlight its poor estimation of its associated mortality. The CFR among infected progeny of pregnant women with syphilis was 31%, due mostly to demise in the third trimester and as such highlights the need for detection and appropriate treatment of syphilis during pregnancy.

Congenital syphilis, a significant cause of fetal mortality worldwide, is a congenital infectious disease instigated by the vertical transmission of Treponema pallidum during pregnancy. Clinical manifestations include preterm delivery, stillbirth, neonatal skin lesions, skeletal abnormalities, and central nervous system aberrations. The ongoing increase in the incidence of congenital syphilis, coupled with complexities in diagnosis, necessitates a detailed understanding of its pathogenesis for the development of improved diagnostic approaches, and to interrupt the route of vertical transmission. Drawing from the broader body of research associated with vertical transmission pathogens, we aim to clarify the potential mechanisms by which Treponema pallidum breaches the placental barrier to infect the fetus.

BACKGROUND: Data on the incidence and characteristics of stillbirths attributed to congenital syphilis were collected. METHODS: We extracted data on stillbirths in the Edmonton Zone on January 1, 2015, through June 30, 2021, born to persons diagnosed with infectious syphilis (primary, secondary, early latent, or early neurosyphilis) during pregnancy or at the time of delivery. RESULTS: Of 314 infants documented to be exposed to infectious syphilis during gestation, 16 (5.1%) were stillborn. Three of the 16 females with stillbirths were diagnosed with syphilis during pregnancy but not treated, 12 were diagnosed only at the time of stillbirth (1 of whom was treated early in pregnancy and presumably reinfected), and 1 had a stillbirth in the week after one dose of benzathine penicillin G. CONCLUSIONS: Stillbirths due to congenital syphilis were all due to failure to treat syphilis in pregnancy. Innovative strategies to prevent syphilis in the community and to reach those experiencing barriers to care are urgently required to not miss opportunities to diagnose and treat syphilis as early as possible during pregnancy.

BACKGROUND: Syphilis notifications in Victoria, Australia, have been increasing over the past decade, with an increase in infectious syphilis (syphilis of less than 2 years in duration) cases in females of reproductive age and an associated reemergence of congenital syphilis (CS). Before 2017, there had been 2 CS cases in the preceding 26 years. This study describes the epidemiology of infectious syphilis among females of reproductive age and CS in Victoria. METHODS: Routine surveillance data provided by mandatory Victorian syphilis case notifications were extracted and grouped into a descriptive analysis of infectious syphilis and CS incidence data from 2010 to 2020. RESULTS: In 2020, infectious syphilis notifications in Victoria were approximately 5 times more than 2010 (n = 289 in 2010 to n = 1440 in 2020), with a more than 7-fold rise among females (n = 25 in 2010 to n = 186 in 2020). Females made up 29% (n = 60 of 209) of Aboriginal and Torres Strait Islander notifications occurring between 2010 and 2020. Between 2017 and 2020, 67% of notifications in females (n = 456 of 678) were diagnosed in low-caseload clinics, at least 13% (n = 87 of 678) of all female notifications were known to be pregnant at diagnosis, and there were 9 CS notifications. CONCLUSIONS: Cases of infectious syphilis in females of reproductive age and CS are on the rise in Victoria, necessitating sustained public health action. Increasing awareness among individuals and clinicians, and health system strengthening, particularly targeting primary care where most females are diagnosed before pregnancy, are required. Treating infections before or promptly during pregnancy and undertaking partner notification and treatment to reduce risk of reinfection are critical to reducing CS cases.
