Abstract
OBJECTIVE The objective of this study is to provide a direct short-term cost-avoidance analysis of expanded three-time prenatal syphilis screening in the context of Manitoba's ongoing outbreak. METHODS A conservative modelling approach increased all financial costs of prenatal screening and minimized the direct costs of congenital syphilis treatment. The cost of syphilis screening was calculated using instrument, reagent and consumable costs as well as laboratory overhead and labour costs as documented by Cadham Provincial Laboratory. The short-term direct costs of treating congenital syphilis were calculated using hospital costs and doctor's billing fees. All costs were calculated in 2021 Canadian dollars. These numbers were applied to Manitoba's 2021 congenital syphilis statistics to provide a pragmatic cost-avoidance analysis. RESULTS The cost of applying three-time prenatal syphilis screening to all 16,800 yearly pregnancies in Manitoba equalled CAD $139,608.00 per year. The direct short-term cost of treating one uncomplicated case of congenital syphilis was $18,151.40. As 81 cases of congenital syphilis were treated in Manitoba in 2021, the short-term direct cost of treating congenital syphilis in Manitoba in 2021 was $1,470,263.40. Applying screening costs to the 125 adequately prevented cases of congenital syphilis in 2021, the screening program is associated with a cost-avoidance ratio of 16.25. If no prenatal syphilis program existed in Manitoba, an expanded screening program would be associated with a cost-avoidance ratio of 26.8. CONCLUSION Expanding prenatal syphilis screening is highly cost-avoidant in Manitoba. The 81 cases of congenital syphilis treated in Manitoba in 2021 highlight the need for novel community-based approaches to increase accessibility and engagement with prenatal care.

Abstract
Despite universal prenatal syphilis screening recommendations and availability of effective antibiotic treatment, syphilis prevalence during pregnancy and the incidence of congenital syphilis have continued to increase in the United States (1,2). Concurrent increases in methamphetamine, injection drug, and heroin use have been described in women with syphilis (3). CDC used data on births that occurred during January 1, 2018-December 31, 2021, from two states (Arizona and Georgia) that participate in the Surveillance for Emerging Threats to Pregnant People and Infants Network (SET-NET) to describe the prevalence of substance use among pregnant persons with syphilis by congenital syphilis pregnancy outcome (defined as delivery of a stillborn or live-born infant meeting the surveillance case definition for probable or confirmed congenital syphilis). The prevalence of substance use (e.g., tobacco, alcohol, cannabis, illicit use of opioids, and other illicit, nonprescription substances) in persons with a congenital syphilis pregnancy outcome (48.1%) was nearly double that among those with a noncongenital syphilis pregnancy outcome (24.6%). Persons with a congenital syphilis pregnancy outcome were six times as likely to report illicit use of opioids and four times as likely to report using other illicit, nonprescription substances during pregnancy than were persons with a noncongenital syphilis pregnancy outcome. Approximately one half of persons who used substances during pregnancy and had a congenital syphilis pregnancy outcome had late or no prenatal care. Tailored interventions should address barriers and facilitators to accessing screening and treatment for syphilis among persons who use substances. The need for syphilis screening and treatment should be addressed at any health care encounter during pregnancy, especially among persons who use substances.

Abstract
OBJECTIVES We aimed to describe the challenges and outcomes of implementing a national syphilis follow-up system to improve syphilis management in maternal and child health (MCH) services in Cambodia. DESIGN Operational study; quantitative cohort data and cross sectional qualitative data. SETTING Public health facilities at national level and in four provinces with high syphilis prevalence in Cambodia. PARTICIPANTS Pregnant women screened for syphilis; MCH health care providers and managers. METHODS We conducted an operational research using syphilis screening and treatment data collected from a national follow-up system (cohort data) and reported in the health management information system (HMIS) between 2019 and 2020. We also conducted indepth interviews with 16 pregnant women and focus group discussions with 37 healthcare providers and managers. Descriptive statistics and thematic content analysis were used. OUTCOME MEASURES Syphilis testing and treatment results and perceptions regarding these services. RESULTS A total of 470 pregnant women who tested positive in rapid syphilis testing were recorded in the national syphilis follow-up system in 2019-2020. Of these, 71% (332 of 470) received a rapid plasma reagin (RPR) test and 95% (n=315) tested positive; 78% (246 of 315) received any syphilis treatment and only 28% (88 of 315) were treated adequately with benzathine penicillin G (BPG). Data from four provinces with high syphilis prevalence (more closely monitored) showed higher testing and treatment rates than at the national level. HMIS aggregated data reported a higher number of pregnant women screened and treated for syphilis than the follow-up system during the same period. Barriers to syphilis testing and treatment included late antenatal care, long distance to RPR testing and treatment, partners' lack of support to reach the health facility, BPG stockout and poor adherence to oral treatment in the absence of BPG. Providers and managers reported a lack of communication across services, insufficient skills to treat infants and absence of clear guidance regarding the revised follow-up system. Study findings contributed to changes in operating procedures nationwide to facilitate access to syphilis testing and adequate treatment and a systematic follow-up of pregnant women and exposed infants. CONCLUSIONS Study results contributed to informing improvements to syphilis management in MCH services in Cambodia.

Abstract
Congenital syphilis is a significant public health problem. Pregnant women infected with Treponema pallidum present with various clinical manifestations, mainly including skin or visceral manifestations. The extensive clinical manifestations of T. pallidum infection mimic those of many other diseases during pregnancy, which may lead to delayed diagnosis and serious consequences. We report a case of fetal T. pallidum infection and premature delivery in a woman whose syphilis screening was negative at 16 weeks of gestation. Despite presenting to the dermatologist at 24 weeks of gestation with maculopapular rash which is usually associated with secondary syphilis, the diagnosis of syphilis was not considered. This case shows that even if early syphilis screening of pregnant women is negative, they may still get infected with T. pallidum later on in pregnancy. Therefore, in patients presenting with a rash without an obvious cause, T. pallidum infection should be excluded. The health status of patients' spouses should be assessed during pregnancy. Additionally, perinatal health education is necessary for women and their spouses during pregnancy. The abovementioned factors could reduce the probability of T. pallidum infection in pregnant women and their infants.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16456. [PMID: 36554342 PMCID: PMC9778377 DOI: 10.3390/ijerph192416456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 11/22/2022] [Accepted: 11/29/2022] [Indexed: 06/17/2023]
Abstract
The increased number of cases in recent years has turned syphilis into a global public health problem. In 2020, 115,371 cases of acquired syphilis were reported (detection rate of 54.5 cases/100,000 inhabitants) in Brazil. In that same period, the country notified 61,441 cases of gestational syphilis (detection rate of 21.6 per 1000 live births). The number of syphilis cases points to the need to reinforce surveillance, prevention, and infection control actions, which is a worrying scenario for government organizations. This study aims to describe the temporal trend of gestational syphilis from 2008 to 2018 in Brazilian regions and to associate its detection rate with socioeconomic and health care indicators. We conducted an ecological study of temporal trends using secondary data from the Department of Informatics of the Unified Health System. The temporal trend was analyzed using the Joinpoint Regression program. The annual percent change (APC) and 95% confidence intervals (95%CI) were estimated and tested; statistical significance was assessed using the Monte Carlo permutation test. Correlations were assessed using Pearson's correlation coefficient, and statistical significance was calculated using Pearson's product-moment correlation. The gestational syphilis detection rate increased between 2008 and 2018. The South region showed the greatest trend, whereas the Midwest region presented the lowest trend. The following variables were significantly correlated with the gestational syphilis detection rate: Municipal Human Development Index, illiteracy rate, percentage of primary health care coverage, and proportion of doctors, nurses, and basic health units per inhabitant. Health policies are needed to mitigate social vulnerabilities and strengthen primary health care.

Abstract
OBJECTIVES As, cases of congenital syphilis (CS) and infectious syphilis among women more than doubled in Florida and across the nation during 2013-2019, we sought to understand what may be contributing to these increases in Florida. DESIGN A two time-period observational study. SETTING Pregnant women with reported syphilis infections and their pregnancy outcomes (2013-2014 and 2018-2019) in Florida. PARTICIPANTS 1213 pregnant women with reported syphilis infections living in Florida and 341 infants meeting the CS case definition. OUTCOME MEASURES We assessed what proportion of the increase in CS was from increases in maternal syphilis infections. We examined maternal demographics, infection characteristics and timing of diagnoses that could explain the increase in CS. Finally, we reviewed if changes in presentation or severity of CS cases occurred. RESULTS During 2013-2014, 83 (21%) of 404 pregnant women with syphilis delivered babies with CS. During 2018-2019, 258 (32%) of 809 pregnant women with syphilis delivered babies with CS. Comparing CS prevention rates, it was determined that 65% of the increase in CS was due to the increases in maternal syphilis infections. The proportion of maternal cases staged as primary or secondary increased over time (7%-13%) (p<0.01) and reports of drug use became slightly more common (6%-10%) (p=0.02). During 2018-2019, women delivering CS infants were more likely to be reinfected during the same pregnancy (27 (10%) vs 5 (6%) p=0.23) and more had negative third trimester screening tests (43 (17%) vs 7 (8% p=0.07)). The percentage of infants with CS who had ≥1 sign or symptom increased from 35% to 40%, and the combined total of stillbirths and infant deaths increased from 5 to 26. CONCLUSIONS Recently, more pregnant women are being infected with syphilis and a higher per cent are not being treated to prevent CS. The reasons for this finding are unclear.

Abstract
(1) Background: Maternal syphilis (MS) and congenital syphilis (CS) are serious public health problems worldwide due to their high morbidity and mortality rates. (2) Objective: Evaluating the applicability of Clinical Protocols and Treatment Guidelines on case incidence trends in Brazil and Portugal. (3) Methods: The review was done through bibliographic research in two public databases and government websites from both countries, published between 2007 and 2022. All guidelines that contained CS and MS were selected. (4) Results and discussion: After evaluation, we found that Brazil and Portugal have adequate protocols for screening and treating congenital and maternal syphilis. (5) Conclusion: The results suggest that CS and MS incidence are notably higher in Brazil than in Portugal due to economic, cultural, and social disparities and the differences in territory size. Therefore, these demographic and socioeconomic factors could strongly influence efforts to fight against syphilis and thus control the infection.

Abstract
BACKGROUND An infectious syphilis outbreak in Alberta has resulted in increased congenital syphilis (CS) cases. To shed light on potential risk factors, we used administrative data sets to examine care milestones for the prevention of CS among pregnant women diagnosed with syphilis, as well as correlates of women giving birth to infants with CS. METHODS Provincial administrative databases were used to identify and describe pregnant women diagnosed with any stage of infectious or noninfectious syphilis who gave birth in Alberta between January 1, 2017, and December 31, 2019. Data on prenatal care, syphilis screening, and syphilis medication dispensation were used to evaluate the care milestones. Clinical care and maternal demographics were assessed using logistic and linear regression analyses to determine correlates for missed care milestones or a newborn outcome of CS. RESULTS Of 182 syphilis-infected pregnant women, 63 (34.6%) delivered a newborn with CS. Overall, in the first trimester, 136 (75.1%) women had a health care visit, 72 (39.6%) had a prenatal care visit, 71 (39.0%) were screened for syphilis, and 44 (24.2%) were treated. Gestational time to treatment initiation (adjusted odds ratio, 1.04; 95% confidence interval, 1.02-1.06) and older maternal age at diagnosis (adjusted odds ratio: 1.28, 95% confidence interval, 1.08-1.50) were independently associated with CS outcomes. No variables were found to be independently associated with a health care visit, prenatal screening, or initiation of treatment. CONCLUSIONS Although nearly two-thirds of CS cases were prevented, there remained missed opportunities in the prevention of CS. Early treatment, which relies on timely access to prenatal care and screening, was the most important for the prevention of CS.

Abstract
BACKGROUND Since 1999, Illinois has had a legal statute mandating both first-visit and third-trimester syphilis testing in all pregnancies. However, the incidence of syphilis infection is increasing at the national and state level, including among individuals of reproductive age, conferring risk of congenital syphilis. Although state-mandated infectious disease screening is purported to be a strategy to improve equity and quality of care, adherence to such mandates and disparities in adherence are unknown. OBJECTIVE We sought to evaluate compliance with state-mandated third-trimester syphilis testing at a single tertiary hospital in Illinois and to identify disparities in testing. STUDY DESIGN This is a retrospective cohort study of all pregnant individuals who delivered between January 1, 2015 and February 28, 2018 at a large-volume academic center. Patients who delivered after 28 weeks of gestation were included. Frequency of state-mandated first-visit (<28 weeks) and third-trimester (≥28 weeks) syphilis screening was evaluated over the study period. The primary outcome was completion of any third-trimester screening (ie, performed as an initial or repeat test in the third trimester) in accordance with state law. Demographic and clinical factors associated with the primary outcome and with completion of both first-visit and third-trimester screening were evaluated with multivariable logistic regression. RESULTS Of the 9048 eligible deliveries, 96.9% (N=8766) of patients had first-visit syphilis screening, whereas only 27.3% (N=2469) had third-trimester screening. Performance of third-trimester syphilis testing increased over time from an average of 5.8% of deliveries during the first 6 months of the study period to 59.8% over the last 6 months of the study period. Non-Hispanic Black or Hispanic race or ethnicity, non-English primary language, public insurance, age <25, multiparity, and greater body mass index were independently associated with increased odds of third-trimester screening. CONCLUSION Despite a decades-old state mandate for third-trimester syphilis screening in this high-prevalence region, third-trimester screening performance was suboptimal. Several demographic characteristics were associated with adherence to screening, suggesting inequity and bias exist in testing practices. It is important to acknowledge that legal statutes do not fully eliminate bias and health disparities.

Abstract
Congenital syphilis (CS) remains a threat to public health worldwide, especially in developing countries. To mitigate the impacts of the CS epidemic, the Brazilian government has developed a national intervention project called "Syphilis No." Thus, among its range of actions is the production of thousands of writings featuring the experiences of research and intervention supporters (RIS) of the project, called field researchers. In addition, this large volume of base data was subjected to analysis through data mining, which may contribute to better strategies for combating syphilis. Natural language processing is a form of knowledge extraction. First, the database extracted from the "LUES Platform" with 4,874 documents between 2018 and 2020 was employed. This was followed by text preprocessing, selecting texts referring to the field researchers' reports for analysis. Finally, for analyzing the documents, N-grams extraction (N = 2,3,4) was performed. The combination of the TF-IDF metric with the BoW algorithm was applied to assess terms' importance and frequency and text clustering. In total, 1019 field activity reports were mined. Word extraction from the text mining method set out the following guiding axioms from the bigrams: "confronting syphilis in primary health care;" "investigation committee for congenital syphilis in the territory;" "municipal plan for monitoring and investigating syphilis cases through health surveillance;" "women's healthcare networks for syphilis in pregnant;" "diagnosis and treatment with a focus on rapid testing." Text mining may serve public health research subjects when used in parallel with the conventional content analysis method. The computational method extracted intervention activities from field researchers, also providing inferences on how the strategies of the "Syphilis No" Project influenced the decrease in congenital syphilis cases in the territory.

Abstract
BACKGROUND The persistence of congenital syphilis (CS) remains an important concern in the United States. We use the 2018 data to refine a previous predictive model that identifies US counties at elevated risk for CS in 2018. METHODS Using county-level socioeconomic and health-related data from various sources, we developed a logistic regression predictive model to identify county-level factors associated with a county having had 1 or more CS case reported to the National Notifiable Diseases Surveillance System in 2018. We developed a risk scoring algorithm, identified the optimal risk score cutpoint to identify counties at elevated risk, and calculated the live birth to CS case ratio for counties by predicted risk level to compare counties at elevated risk with counties not at elevated risk. RESULTS We identified several county-level factors associated with a county having 1 or more CS case in 2018 (area under the curve, 88.6%; Bayesian information criterion, 1551.1). Using a risk score cutoff of 8 or higher (sensitivity, 83.2%; specificity, 79.4%), this model captured 94.7% (n = 1,253) of CS cases born in 2018 and identified 850 (27%) counties as being at elevated risk for CS. The live birth to CS case ratio was lower in counties identified as at elevated risk (2,482) compared with counties categorized as not at elevated risk (10,621). CONCLUSIONS Identifying which counties are at highest risk for CS can help target prevention efforts and interventions. The relatively low live birth to CS case ratio in elevated risk counties suggests that implementing routine 28-week screening among pregnant women in these counties may be an efficient way to target CS prevention efforts.

Abstract
Congenital syphilis (CS) is on the rise in the United States and is a growing public health concern. CS is an infection with Treponema pallidum in an infant or fetus, acquired via transplacental transmission when a pregnant woman has untreated or inadequately treated syphilis. Pregnant women with untreated syphilis are more likely to experience pregnancies complicated by stillbirth, prematurity, low birth weight, and early infant death, while their children can develop clinical manifestations of CS such as hepatosplenomegaly, bone abnormalities, developmental delays, and hearing loss. One of the ways CS can be prevented is by identifying and treating infected women during pregnancy with a benzathine penicillin G regimen that is both appropriate for the maternal stage of syphilis and initiated at least 30 days prior to delivery. In this article we discuss many of the challenges faced by both public health and healthcare systems with regards to this preventable infection, summarize missed opportunities for CS prevention, and provide practical solutions for future CS prevention strategies.

Abstract
Congenital syphilis is the result of placental transmission from mother to fetus of Treponema pallidum. Although congenital syphilis is preventable through timely treatment, the rate of new infections in the United States (US) has increased each year since 2013, and is increasing at a noticeably greater pace in California (CA). Most research into congenital syphilis has focused on individual psychosocial and behavioral factors that contribute to maternal vulnerability for syphilis. The aim of this study was to evaluate structural barriers to prenatal care access and utilization and congenital syphilis prevention in Kern County, CA. Transcripts from 8 in-depth interviews with prenatal care providers and 5 focus group discussions with 42 pregnant and postpartum persons were examined using thematic analysis. Structural barriers experienced by pregnant and postpartum persons to prenatal care access and utilization included (1) burdens of poverty; (2) stigma around substance use in pregnancy; (3) citizenship status; (4) lack of healthcare coverage; (5) low sexual health literacy; and (6) gender inequality Structural barriers experienced by prenatal care providers in congenital syphilis prevention included (1) limited guidance on clinical management of syphilis in pregnancy; (2) decay in public health infrastructure; and (3) inadequate support for managing patients' social comorbidities. The response to congenital syphilis prevention will require an examination of the complex context of social determinants of health in which persons diagnosed with syphilis live in.

Abstract
BACKGROUND Despite an otherwise robust national antenatal clinic program, maternal and congenital syphilis remains an important public health issue in Zambia. This case series reports the clinical presentation of seven infants diagnosed with congenital syphilis in Lusaka, Zambia. CASE PRESENTATIONS The cases in this series were incidental findings from a cohort of infants enrolled in a rotavirus vaccine immunogenicity study recruiting infants at 6 weeks of age. As part of clinical care for enrolled participants, we screened mothers of children who presented with adverse events of (i) repeated upper respiratory tract infections/coryza, (ii) skin lesions, and (iii) poor weight gain, for syphilis using rapid plasma reagin test. From a cohort of 214 mother-infant pairs enrolled between September and December 2018, a total of 115 (44.4%) of the mothers reported to have not been screened during antenatal care. Of these, four (3.5%) reported to have tested positive; and only two received treatment. Seven out of 57 (26.6%) children meeting the screening criteria had a positive rapid plasma reagin test result. The mean age at diagnosis was 4.5 months (1.3 months standard deviation), and the common presenting features included coryza (6/7), skin lesions (4/7), conjunctivitis (3/7), pallor/anemia (5/7), wasting (2/7), and underweight (5/7). Three of the seven infants were exposed to human immunodeficiency virus. Following diagnosis, all seven cases received standard treatment according to national treatment guidelines. That is, 6/7 cases received inpatient care with benzylpenicillin for 10 days, while 1/7 was treated as an outpatient and received daily procaine penicillin for 10 days. CONCLUSION These findings suggest that, though screening for syphilis is part of the standard antenatal care in Zambia, it is not offered optimally. There is urgent need to address programmatic shortcomings in syphilis screening and treatment to avoid long-term sequelae. Additionally, clinicians need to raise their index of suspicion and rule out syphilis when confronted with these clinical symptoms, regardless of the mother's human immunodeficiency virus status.

Abstract
Rates of primary, secondary, and congenital syphilis are increasing in the United States, and reversing this trend requires renewed vigilance on the part of family physicians to assist public health agencies in the early detection of outbreaks. Prompt diagnosis of syphilis can be challenging, and not all infected patients have common manifestations, such as a genital chancre or exanthem. The U.S. Preventive Services Task Force recommends screening for syphilis in all patients at increased risk, particularly those who reside in high-prevalence areas, sexually active people with HIV infection, and men who have sex with men. Other groups at increased risk include males 29 years or younger and people with a history of incarceration or sex work. All pregnant women should be screened for syphilis at the first prenatal visit, and those at increased risk should be screened throughout the pregnancy. The Centers for Disease Control and Prevention recommends the traditional screening algorithm for most U.S. populations. Penicillin is the preferred treatment across all stages of syphilis, although limited research suggests a possible role for other antibiotics in penicillin-allergic patients with primary or secondary syphilis. Pregnant women with syphilis who are allergic to penicillin should undergo penicillin desensitization before treatment.

Global burden of maternal and congenital syphilis and associated adverse birth outcomes-Estimates for 2016 and progress since 2012. PLoS One 2019; 14:e0211720. [PMID: 30811406 PMCID: PMC6392238 DOI: 10.1371/journal.pone.0211720] [Citation(s) in RCA: 177] [Impact Index Per Article: 35.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Accepted: 10/26/2018] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND In 2007 the World Health Organization (WHO) launched the global initiative to eliminate mother-to-child transmission of syphilis (congenital syphilis, or CS). To assess progress towards the goal of <50 CS cases per 100,000 live births, we generated regional and global estimates of maternal and congenital syphilis for 2016 and updated the 2012 estimates. METHODS Maternal syphilis estimates were generated using the Spectrum-STI model, fitted to sentinel surveys and routine testing of pregnant women during antenatal care (ANC) and other representative population data. Global and regional estimates of CS used the same approach as previous WHO estimates. RESULTS The estimated global maternal syphilis prevalence in 2016 was 0.69% (95% confidence interval: 0.57-0.81%) resulting in a global CS rate of 473 (385-561) per 100,000 live births and 661,000 (538,000-784,000) total CS cases, including 355,000 (290,000-419,000) adverse birth outcomes (ABO) and 306,000 (249,000-363,000) non-clinical CS cases (infants without clinical signs born to un-treated mothers). The ABOs included 143,000 early fetal deaths and stillbirths, 61,000 neonatal deaths, 41,000 preterm or low-birth weight births, and 109,000 infants with clinical CS. Of these ABOs- 203,000 (57%) occurred in pregnant women attending ANC but not screened for syphilis; 74,000 (21%) in mothers not enrolled in ANC, 55,000 (16%) in mothers screened but not treated, and 23,000 (6%) in mothers enrolled, screened and treated. The revised 2012 estimates were 0.70% (95% CI: 0.63-0.77%) maternal prevalence, and 748,000 CS cases (539 per 100,000 live births) including 397,000 (361,000-432,000) ABOs. The estimated decrease in CS case rates between 2012 and 2016 reflected increased access to ANC and to syphilis screening and treatment. CONCLUSIONS Congenital syphilis decreased worldwide between 2012 and 2016, although maternal prevalence was stable. Achieving global CS elimination, however, will require improving access to early syphilis screening and treatment in ANC, clinically monitoring all women diagnosed with syphilis and their infants, improving partner management, and reducing syphilis prevalence in the general population by expanding testing, treatment and partner referral beyond ANC.
