Abstract
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.

Abstract
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.

Abstract
Introduction Congenital syphilis cases in the United States increased 755% during 2012-2021. Syphilis during pregnancy can lead to stillbirth, miscarriage, infant death, and maternal and infant morbidity; these outcomes can be prevented through appropriate screening and treatment. Methods A cascading framework was used to identify and classify missed opportunities to prevent congenital syphilis among cases reported to CDC in 2022 through the National Notifiable Diseases Surveillance System. Data on testing and treatment during pregnancy and clinical manifestations present in the newborn were used to identify missed opportunities to prevent congenital syphilis. Results In 2022, a total of 3,761 cases of congenital syphilis in the United States were reported to CDC, including 231 (6%) stillbirths and 51 (1%) infant deaths. Lack of timely testing and adequate treatment during pregnancy contributed to 88% of cases of congenital syphilis. Testing and treatment gaps were present in the majority of cases across all races, ethnicities, and U.S. Census Bureau regions. Conclusions and implications for public health practice Addressing missed opportunities for prevention, primarily timely testing and appropriate treatment of syphilis during pregnancy, is important for reversing congenital syphilis trends in the United States. Implementing tailored strategies addressing missed opportunities at the local and national levels could substantially reduce congenital syphilis.

BMC Health Serv Res 2023; 23:906. [PMID: 37620909 PMCID: PMC10463716 DOI: 10.1186/s12913-023-09913-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 08/14/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Evidence indicates that antenatal care (ANC) has both indirect and direct effects on maternal and perinatal morbidity and mortality reduction. In Uganda, the ANC attendance rate stands at 97.3% for one visit, but 59.9% for four or more visits. Given the imminent shift to the eight-contact ANC model in Uganda, combined with a lack of universal coverage for completion of four ANC visits, there is need for research that provides information on the factors that differentiate completers of recommended ANC attendances from non-completers. The aim of this quantitative study was to assess service- level factors affecting completion of ANC attendance defined by completion of four or more visits among women of reproductive age in Iganga district in Uganda. METHODS Facility assessment scores on the service-level factors of interest for health facilities were obtained using a service level index tool. The relationship between the ANC completion rates of clients sampled from records at the health facilities and facility scores on service-level factors of interest were analyzed. Regression was conducted to determine the predictive relationship between ANC service availability, ANC service content, and ANC service organization, and completion of ANC attendance. RESULTS The model was statistically significant, χ2 (6) = 26.118, p ˂ 0.05, and accounted for approximately 17.3% of the variance of ANC attendance completion (R2 = .173). Completion of ANC attendance was primarily predicted by better timing of provision of ANC services, and to a lesser extent by higher levels of availability of medicines and medical supplies. CONCLUSIONS This study demonstrated that service-level factors have a predictive value for completion of ANC attendance. The findings can be used to improve availability, content, and organization of ANC services with the aim of enhancing positive experiences for clients and motivating them to complete the recommended number of ANC visits.

Abstract
Syphilis is a treponemal infection that can be acquired sexually, hematogenously, or via vertical transmission from mother to infant. Despite evidence-based curative treatment options with penicillin, it remains a public health threat with increasing prevalence over recent years. Congenital syphilis, a condition where a fetus acquires the infection during pregnancy, can lead to stillbirth, miscarriage, preterm birth, birth defects, and lifelong physical or neurologic changes. Congenital syphilis rates in the United States increased by 261% from 2013 to 2018 and continue to increase in 2021. The only recommended treatment for syphilis in pregnancy is benzathine penicillin G because evidence of decreased risk of congenital syphilis with other modalities is lacking. Testing for syphilis is complex and includes either the reverse-sequence algorithm or the traditional algorithm. Determination of the clinical stage of syphilis includes incorporation of the previous treatment sequence and physical examination. The goal of this review was to discuss the current evidence about optimal treatment and testing during pregnancy to optimize maternal health and prevent congenital syphilis.

Abstract
Maternal syphilis remains a major contributor to poor pregnancy outcomes. Syphilis point-of-care (POC) tests are now used for pregnancy screening; the effect of screening on outcomes is unclear. We enrolled women presenting to antenatal care (ANC) in a matched cohort study at a single site in Kenya tested by either a syphilis-only or an HIV/syphilis dual POC test. Syphilis POC-positive women (patients) were matched 1:2 with POC-negative women (control subjects) on gravidity, gestational age, and HIV status, and were monitored through delivery. Syphilis serum testing was performed every 8 weeks. Pregnancy outcomes were assessed up to 1 month after delivery and compared using prevalence ratios. A total of 151 women were enrolled (51 patients and 100 control subjects) at a mean of 22 weeks gestation; 24% were HIV positive and 40% were paucigravid. A positive Treponema pallidum hemagglutination test was more common among patients (64.7%) than control subjects (11.1%, P < 0.001). Only two women met the definition for incident syphilis. Pregnancy outcomes were available for 147 women. The prevalence of low birthweight (LBW) was greater among patients (15.2%) than control subjects (5.4%, P = 0.052). Of the 109 women with concordant syphilis POC and Treponema pallidum hemagglutination test results at ANC enrollment, LBW prevalence was significantly greater among test-positive (25%) than test-negative (4.9%) women (adjusted prevalence ratio, 5.84; 95% CI, 1.08-31.5). Despite treatment with penicillin, latent syphilis at ANC enrollment was associated with a more than 5-fold increased risk of LBW. Alternate implementation strategies for syphilis POC testing may be necessary to realize the potential of ANC syphilis screening to improve pregnancy outcomes.

BMC Infect Dis 2022; 22:561. [PMID: 35725437 PMCID: PMC9208134 DOI: 10.1186/s12879-022-07534-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 06/13/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Sexually transmitted infections (STIs) in low- and middle-income countries (LMICs) are predominantly managed by syndromic management. However, most STIs are asymptomatic. These untreated STIs cause individual morbidity, and lead to high STI prevalences. There is increasing interest in the use of point-of-care tests (POCTs) for STIs in LMICs, which could facilitate same day testing and treatment. To best utilise these tests, we must understand the facilitators and barriers to their implementation. The aim of this review is to explore how point-of-care testing for STIs has been implemented into healthcare systems in LMIC and the facilitators and barriers to doing so. METHODS A scoping review was conducted by searching MEDLINE, Embase, Emcare, CINAHL, Scopus, LILACS, the Cochrane Library, and ProQuest Dissertations and Theses for studies published between 1st January 1998 and 5th June 2020. Abstracts and full articles were screened independently by two reviewers. Studies were considered for inclusion if they assessed the acceptability, feasibility, facilitators, or barriers to implementation of point-of-care testing for chlamydia, gonorrhoea, trichomoniasis or syphilis in LMICs. Thematic analysis was used to analyse and present the facilitators and barriers to point-of-care STI testing. RESULTS The literature search revealed 82 articles suitable for inclusion; 44 (53.7%) from sub-Saharan Africa; 21 (25.6%) from Latin American and the Caribbean; 10 (12.2%) from East Asia and the Pacific; 6 (7.3%) from South Asia; and one (1.2%) multi-regional study. Thematic analysis revealed seven overarching themes related to the implementation of POCTs in LMICs, namely (i) Ideal test characteristics, (ii) Client factors, (iii) Healthcare provision factors, (iv) Policy, infrastructure and health system factors, (v) Training, audit, and feedback, (vi) Reaching new testing environments, and (vii) Dual testing. CONCLUSION Implementation of POCTs in LMICs is complex, with many of the barriers due to wider health system weakness. In addition to pressing for broader structural change to facilitate basic healthcare delivery, these themes may also be used as a basis on which to develop future interventions. The literature was heavily skewed towards syphilis testing, and so more research needs to be conducted assessing chlamydia, gonorrhoea, and trichomoniasis testing, as well as home or self-testing.

Abstract
BACKGROUND Point-of-care testing for sexually transmitted infections (STIs) may improve diagnosis and treatment of STIs in low- and middle-income counties. We explored the facilitators and barriers to point-of-care testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoea (NG) for youth in community-based settings in Zimbabwe. METHODS This study was nested within a cluster randomised trial of community-based delivery of integrated HIV and sexual and reproductive health services for youth aged 16 to 24 years. On-site CT/NG testing on urine samples using the Xpert® CT/NG test was piloted in four intervention clusters, with testing performed by service providers. On-site testing was defined as sample processing on the same day and site as sample collection. Outcomes included proportion of tests processed on-site, time between sample collection and collection of results, and proportion of clients receiving treatment. In-depth interviews were conducted with nine service providers and three staff members providing study co-ordination or laboratory support to explore facilitators and barriers to providing on-site CT/NG testing. RESULTS Of 847 Xpert tests, 296 (35.0%) were performed on-site. Of these, 61 (20.6%) were positive for CT/NG; one (1.6%) received same day aetiological treatment; 33 (54.1%) presented later for treatment; and 5 (8.2%) were treated as a part of syndromic management. There was no difference in the proportion of clients who were treated whether their sample was processed on or off-site (64% (39/61) vs 60% (66/110); p = 0.61). The median (IQR) number of days between sample collection and collection of positive results was 14 (7-35) and 14 (7-52.5) for samples processed on and off-site, respectively, The interviews revealed four themes related to the provision of on-site testing associated with the i) diagnostic device ii) environment, iii) provider, and iv) clients. Some of the specific barriers identified included insufficient testing capacity, inadequate space, as well as reluctance of clients to wait for their results. CONCLUSIONS In addition to research to optimise the implementation of point-of-care tests for STIs in resource-limited settings, the development of new platforms to reduce analytic time will be necessary to scale up STI testing and reduce the attrition between testing and treatment.

Brandenburger D, Ambrosino E. The impact of antenatal syphilis point of care testing on pregnancy outcomes: A systematic review. PLoS One 2021; 16:e0247649. [PMID: 33765040 PMCID: PMC7993761 DOI: 10.1371/journal.pone.0247649] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 02/10/2021] [Indexed: 12/26/2022] Open
Abstract
Background Mother-to-child transmission of syphilis remains a leading cause of neonatal death and stillbirth, disproportionally affecting women in low-resource settings where syphilis prevalence rates are high and testing rates low. Recently developed syphilis point-of-care tests (POCTs) are promising alternatives to conventional laboratory screening in low-resource settings as they do not require a laboratory setting, intensive technical training and yield results in 10–15 minutes thereby enabling both diagnosis and treatment in a single visit. Aim of this review was to provide clarity on the benefits of different POCTs and assess whether the implementation of syphilis POCTs is associated with decreased numbers of syphilis-related adverse pregnancy outcomes. Methods Following the PRISMA guidelines, three electronic databases (PubMed, Medline (Ovid), Cochrane) were systematically searched for intervention studies and cost-effectiveness analyses investigating the association between antenatal syphilis POCT and pregnancy outcomes such as congenital syphilis, low birth weight, prematurity, miscarriage, stillbirth as well as perinatal, fetal or infant death. Results Nine out of 278 initially identified articles were included, consisting of two clinical studies and seven modelling studies. Studies compared the effect on pregnancy outcomes of treponemal POCT, non-treponemal POCT and dual POCT to laboratory screening and no screening program. Based on the clinical studies, significantly higher testing and treatment rates, as well as a significant reduction (93%) in adverse pregnancy outcomes was reported for treponemal POCT compared to laboratory screening. Compared to no screening and laboratory screening, modelling studies assumed higher treatment rates for POCT and predicted the most prevented adverse pregnancy outcomes for treponemal POCT, followed by a dual treponemal and non-treponemal POCT strategy. Conclusion Implementation of treponemal POCT in low-resource settings increases syphilis testing and treatment rates and prevents the most syphilis-related adverse pregnancy outcomes compared to no screening, laboratory screening, non-treponemal POCT and dual POCT. Regarding the benefits of dual POCT, more research is needed. Overall, this review provides evidence on the contribution of treponemal POCT to healthier pregnancies and contributes greater clarity on the impact of diverse diagnostic methods available for the detection of syphilis.

Abstract
Brazil has reported an increase in the incidence of both gestational and congenital syphilis, posing a serious public health problem in the country. The study aimed to analyze the relationship between the supply of syphilis diagnosis and treatment in primary care and the incidence rates of gestational and congenital syphilis. An ecological study analyzed these incidence rates and the coverage of diagnostic and therapeutic measures in primary care. The study sample consisted of municipalities (counties) with population over 20,000, with coverage by primary care over 50%, and where the majority of the teams were assessed in the second cycle of the National Program for Improvement of Access and Quality of Basic Care. Analysis of the effectiveness of detection and treatment measures was based on the development of the Index of Variation in Vertical Syphilis Transmission. The administration of penicillin and application of the rapid test in these municipalities showed median rates of 41.9% and 67.14%, respectively, with regional differences. Median incidence of gestational syphilis was 6.24 (IQR: 2.63-10.99) in municipalities with a higher supply of the rapid test and 3.82 (IQR: 0.00-8.21) in those with a lower supply, indicating an increase in detection capacity. Municipalities with a reduction in vertical transmission showed higher median rates of teams with supply of rapid testing and (83.33%; IQR: 50.00-100.00) and administration of penicillin (50.00%; IQR: 11.10-87.50), demonstrating a relationship between these measures and the reduction in congenital syphilis. The findings indicate the need to expand these services and to reinforce the importance of reducing vertical transmission.

Abstract
BACKGROUND Congenital syphilis (CS)-the preventable transmission of Treponema pallidum from infected mother to fetus-remains a significant problem worldwide. METHODS From July through November 2017, 239 articles relevant to CS prevention were identified via keyword searches in PubMed and Google Scholar, ancestry searches, and expert recommendation. Articles were then assessed for (1) measurement of a specified CS or adverse pregnancy outcomes (APOs) and (2) geographic setting in high/upper middle income countries according to United Nations criteria. In total, 119 articles met inclusion criteria. These were then vetted for 1 of 3 arms of CS prevention, after which additional ancestral searches were conducted within each arm to arrive at the final collection of articles per CS prevention strategy-maternal prenatal treatment (n = 33), prenatal screening (n = 24), and public health interventions that support screening and treatment (n = 15). RESULTS Of the 7 studies that evaluated treatment with benzathine penicillin G (BPG) use within the context of a modern health care system, all showed BPG to be highly effective in CS prevention; 3 additional studies demonstrated BPG effectiveness in preventing APOs. Ten studies revealed early disease detection through prenatal screening significantly reduces CS and APOs when paired with BPG. There was limited literature evaluating public health interventions, such as partner notification, surveillance, and prenatal screening laws. CONCLUSIONS Congenital syphilis is a preventable disease, effectively avoided with appropriate prenatal screening and BPG therapy. Increasing syphilis rates among all adults, accompanied by gaps in the provision of prenatal care to women at high risk of infection, are major contributors to CS persistence.

A multifaceted intervention to improve syphilis screening and treatment in pregnant women in Kinshasa, Democratic Republic of the Congo and in Lusaka, Zambia: a cluster randomised controlled trial. LANCET GLOBAL HEALTH 2019; 7:e655-e663. [PMID: 30910531 PMCID: PMC6465956 DOI: 10.1016/s2214-109x(19)30075-0] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Revised: 12/19/2018] [Accepted: 01/16/2019] [Indexed: 11/11/2022]
Abstract
Background Despite international recommendations, coverage of syphilis testing in pregnant women and treatment of those found seropositive remains limited in sub-Saharan Africa. We assessed whether combining the provision of supplies with a behavioural intervention was more effective than providing supplies only, to improve syphilis screening and treatment during antenatal care. Methods In this 18-month, cluster randomised controlled trial, we randomly assigned (1:1) 26 urban antenatal care clinics in Kinshasa, Democratic Republic of the Congo, and Lusaka, Zambia, to receive a behavioural intervention (opinion leader selection, academic detailing visits, reminders, audits and feedback, and supportive supervision) plus supplies for syphilis testing and treatment (intervention group) or to receive supplies only (control group). The primary outcomes were proportion of pregnant women who had syphilis screening out of the total who attended the clinic; and the proportion of women who had treatment with benzathine benzylpenicillin out of those who tested positive for syphilis at their first antenatal care visit. This trial is registered at ClinicalTrials.gov, number NCT02353117. Findings The 18-month study period was Feb 1, 2016, to July 14, 2017. 18 357 women were enrolled at the 13 intervention clinics and 17 679 women were enrolled at the 13 control clinics at their first antenatal care visit. Syphilis screening was done in a median of 99·9% (IQR 99·0–100·0) of women in the intervention clinics and 93·8% (85·0–98·9) in the control clinics (absolute difference 6·1% [95% CI 1·1–14·1]; p=0·00092). Syphilis treatment at the first visit was done in a median of 100% (IQR 99·7–100·0) of seropositive women in intervention clinics and 43·2% (2·6–83·2) of seropositive women in control clinics (absolute difference 56·8% [12·8–99·0]; p=0·0028). Interpretation A behavioural intervention, together with the provision of supplies, can lead to more than 95% of women being screened and treated for syphilis. The sole provision of supplies is sufficient to reach such levels of screening coverage but is not sufficient to ensure high levels of treatment. Funding Bill & Melinda Gates Foundation.

Prevent Mother-to-Child Transmission (PMTCT) Programs and Enhancement of Maternal Healthcare Infrastructure to Improve Early Detection of Maternal Syphilis in Shanghai, China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16061002. [PMID: 30897696 PMCID: PMC6466554 DOI: 10.3390/ijerph16061002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Revised: 03/12/2019] [Accepted: 03/12/2019] [Indexed: 11/20/2022]
Abstract
This study aimed to compare the screening and diagnosis of maternal syphilis in Shanghai between the national and municipal prevent mother-to-child transmission (PMTCT) of syphilis policies, and then to assess whether PMTCT programs and enhancing healthcare infrastructure could bring about an early detection of maternal syphilis. Detection of maternal syphilis was initiated in 2001 and then scaled-up in 2011 along with the enhancement of antenatal healthcare infrastructure. The initial five-year periods of municipal and national PMTCT policies were defined as the “exploring period” (2002–2006) and the “comprehensive period” (2011–2015). The demographic and gestational weeks (GW) of syphilis screening and diagnosis were analyzed to identify the factors affecting early detection. During the study period, maternal syphilis screening increased from 83,718 in 2002 to 243,432 in 2015. Of the 1,894,062 pregnant women screened, 1526 and 2714 participants were diagnosed with maternal syphilis in 2002–2006 and 2011–2015, respectively. The average age of diagnosis was 28.36 years and non-residents accounted for 71.1%. In the comprehensive period, more women received early syphilis screening (14.0% vs. 10.8%) and diagnosis (13.3% vs. 7.3%) within 12 GWs compared with the exploring period. Significantly, early detection grew during 2011–2015, which was not seen in the exploring period. Multivariate analysis revealed a greater possibility for infected women to be diagnosed within 16 GWs (OR = 2.76) in the comprehensive period, but those who were non-residents and unemployed were less likely to receive early detection. In conclusion, early detection of maternal syphilis has been remarkably improved. More emphasis is required on the development of pro-vulnerable policies and the implementation of tailored health education to improve the accessibility of routine antenatal care and awareness of syphilis prevention.

Global burden of maternal and congenital syphilis and associated adverse birth outcomes-Estimates for 2016 and progress since 2012. PLoS One 2019; 14:e0211720.

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.

Abstract
BACKGROUND Congenital syphilis continues to be a substantial public health problem in many parts of the world. Since the first use of penicillin for the treatment of syphilis in 1943, which was a notable early success, it has remained the preferred and standard treatment including for congenital syphilis. However, the treatment of congenital syphilis is largely based on clinical experience and there is extremely limited evidence on the optimal dose or duration of administration of penicillin or the use of other antibiotics. OBJECTIVES To assess the effectiveness and safety of antibiotic treatment for newborns with confirmed, highly probable and possible congenital syphilis. SEARCH METHODS We searched the Cochrane STI Group Specialized Register, CENTRAL, MEDLINE, Embase, LILACS, WHO ICTRP, ClinicalTrials.gov and Web of Science to 23 May 2018. We also handsearched conference proceedings, contacted trial authors and reviewed the reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing antibiotic treatment (any concentration, frequency, duration and route) with no intervention or any other antibiotic treatment for neonates with confirmed, highly probable or possible congenital syphilis. DATA COLLECTION AND ANALYSIS All review authors independently assessed trials for inclusion, extracted data and assessed the risk of bias in the included studies. We resolved any disagreements through consensus. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS Two RCTs (191 participants) met our inclusion criteria and none of these trials was funded by the industry. One trial (22 participants) compared benzathine penicillin with no intervention for infants with possible congenital syphilis. Low-quality evidence suggested that benzathine penicillin administration may not have decreased the rate of neonatal death due to any cause (risk ratio (RR) 0.83, 95% confidence interval (CI) 0.06 to 11.70), and showed a possible reduction into the proportion of neonates with clinical manifestations of congenital syphilis (RR 0.12, 95% CI 0.01 to 2.09). Penicillin administration increased the serological cure at the third month (RR 2.13, 95% CI 1.06 to 4.27). These results should be taken with caution, because the trial was stopped early because there were four cases with clinical congenital syphilis in the no treatment group and none in the treatment group. Interim analysis suggested this difference was significant. This study did not report neonatal death due to congenital syphilis or the frequency of serious or minor adverse events after therapy. We downgraded the quality of evidence because of imprecision and risk of bias.One trial (169 participants) compared benzathine penicillin versus procaine benzylpenicillin. High- and moderate-quality evidence suggested that there were probably no differences between benzathine penicillin and procaine benzylpenicillin for the outcomes: absence of clinical manifestations of congenital syphilis (RR 1.00, 95% CI 0.97 to 1.03) and serological cure (RR 1.00, 95% CI 0.97 to 1.03). There were no cases of neonatal death due congenital syphilis; all 152 babies who followed up survived. This study did not report on the frequency of serious or minor adverse events after therapy. We downgraded the quality of evidence because of serious risk of bias. AUTHORS' CONCLUSIONS At present, the evidence on the effectiveness and safety of antibiotic treatment for newborns with confirmed, highly probable or possible congenital syphilis is sparse, implying that we are uncertain about the estimated effect. One trial compared benzathine penicillin with no intervention for infants with possible congenital syphilis. Low-quality evidence suggested penicillin administration possibly reduce the proportion of neonates with clinical manifestations of congenital syphilis, penicillin administration increased the serological cure at the third month. These findings support the clinical use of penicillin in neonates with confirmed, highly probable or possible congenital syphilis. High- and moderate-quality evidence suggests that there are probably no differences between benzathine penicillin and procaine benzylpenicillin administration for the outcomes of absence of clinical manifestations of syphilis or serological cure.

Abstract
BACKGROUND The success of an intervention to prevent syphilis will depend on the context and the goal of the intervention. To help programs choose interventions, we reviewed major changes in context and types of interventions that may be effective. METHODS We reviewed the literature on the changing context of syphilis in the United States and interventions to prevent syphilis, focusing on articles that included evidence of effectiveness. RESULTS Populations acquiring syphilis are constantly changing. Currently, incidence is very high among men who have sex with men (MSM). Among adults, late disease caused by syphilis has become rare. Congenital syphilis incidence has been low but is increasing, and morbidity and mortality remain high when babies are infected. Congenital syphilis now causes more deaths than syphilis among adults.Routine screening of MSM can identify and treat infections before they progress to disease (secondary prevention). Screening rates are highest when done as part of routine standing orders. Partner notification effectiveness has decreased, partly because many partners are anonymous. Most congenital syphilis can be prevented by screening pregnant women; it has been eliminated in areas where intense primary prevention efforts eliminated syphilis among women. CONCLUSIONS So far, no program has stopped the increasing rates of infection among MSM, but secondary prevention efforts have prevented most disability. Congenital syphilis is increasing, and can be decreased by screening pregnant women and stopped by intensive efforts to prevent infection among women.

Abstract
Despite growing support for integration of frontline services, a lack of information about the pre-conditions necessary to integrate such services hampers the ability of policy makers and implementers to assess how feasible or worthwhile integration may be, especially in low- and middle-income countries (LMICs). We adopted a modified systematic review with aspects of realist review, including quantitative and qualitative studies that incorporated assessment of health system preparedness for and capacity to implement integrated services. We searched Medline via Ovid, Web of Science and the Cochrane library using terms adapted from Dudley and Garner’s systematic review on integration in LMICs. From an initial list of 10 550 articles, 206 were selected for full-text review by two reviewers who independently reviewed articles and inductively extracted and synthesized themes related to health system preparedness. We identified five ‘context’ related categories and four health system ‘capability’ themes. The contextual enabling and constraining factors for frontline service integration were: (1) the organizational framework of frontline services, (2) health care worker preparedness, (3) community and client preparedness, (4) upstream logistics and (5) policy and governance issues. The intersecting health system capabilities identified were the need for: (1) sufficiently functional frontline health services, (2) sufficiently trained and motivated health care workers, (3) availability of technical tools and equipment suitable to facilitate integrated frontline services and (4) appropriately devolved authority and decision-making processes to enable frontline managers and staff to adapt integration to local circumstances. Moving beyond claims that integration is defined differently by different programs and thus unsuitable for comparison, this review demonstrates that synthesis is possible. It presents a common set of contextual factors and health system capabilities necessary for successful service integration which may be considered indicators of preparedness and could form the basis for an ‘integration preparedness tool’.

Abstract
INTRODUCTION Mongolia's health ministry prioritizes control of Sexually Transmitted Infections, including syphilis screening and treatment in antenatal care (ANC). METHODS Adult syphilis prevalence trends were fitted using the Spectrum-STI estimation tool, using data from ANC surveys and routine screening over 1997-2016. Estimates were combined with programmatic data to estimate numbers of treated and untreated pregnant women with syphilis and associated incidence congenital syphilis (CS) and CS-attributable adverse birth outcomes (ABO), which we compared with CS case reports. RESULTS Syphilis prevalence in pregnant women was estimated at 1.7% in 2000 and 3.0% in 2016. We estimated 652 CS cases, of which 410 ABO, in 2016. Far larger, annually increasing numbers of CS cases and ABO were estimated to have been prevented: 1654 cases, of which 789 ABO in 2016 - thanks to increasing coverages of ANC (99% in 2016), ANC-based screening (97% in 2016) and treatment of women diagnosed (81% in 2016). The 42 CS cases reported nationally over 2016 (liveborn infants only) represented 27% of liveborn infants with clinical CS, but only 7% of estimated CS cases among women found syphilis-infected in ANC, and 6% of all estimated CS cases including those born to women with undiagnosed syphilis. DISCUSSION/CONCLUSION Mongolia's ANC-based syphilis screening program is reducing CS, but maternal prevalence remains high. To eliminate CS (target: <50 cases per 100,000 live births), Mongolia should strengthen ANC services, limiting losses during referral for treatment, and under-diagnosis of CS including still-births and neonatal deaths, and expand syphilis screening and prevention programs.

Abstract
Background Antenatal care (ANC) presents a potentially valuable platform for integrated delivery of additional health services for pregnant women–services that are vital to reduce the persistently high rates of maternal and neonatal mortality in low– and middle–income countries (LMICs). However, there is limited evidence on the impact of integrating health services with ANC to guide policy. This review assesses the impact of integration of postnatal and other health services with ANC on health services uptake and utilisation, health outcomes and user experience of care in LMICs. Methods Cochrane Library, MEDLINE, Embase, CINAHL Plus, POPLINE and Global Health were searched for studies that compared integrated models for delivery of postnatal and other health services with ANC to non–integrated models. Risk of bias of included studies was assessed using the Cochrane Effective Practice and Organisation of Care (EPOC) criteria and the Newcastle–Ottawa Scale, depending on the study design. Due to high heterogeneity no meta–analysis could be conducted. Results are presented narratively. Findings 12 studies were included in the review. Limited evidence, with moderate– to high–risk of bias, suggests that integrated service delivery results in improved uptake of essential health services for women, earlier initiation of treatment, and better health outcomes. Women also reported improved satisfaction with integrated services. Conclusions The reported evidence is largely based on non–randomised studies with poor generalizability, and therefore offers very limited policy guidance. More rigorously conducted and geographically diverse studies are needed to better ascertain and quantify the health and economic benefits of integrating health services with ANC.

Introducing onsite antenatal syphilis screening in Burkina Faso: implementation and evaluation of a feasibility intervention tailored to a local context. BMC Health Serv Res 2017; 17:378. [PMID: 28558812 PMCID: PMC5450306 DOI: 10.1186/s12913-017-2325-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2015] [Accepted: 05/19/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although the advantages of introducing point of care testing for syphilis in antenatal care (ANC) are well documented, there is little evidence on how to address structural issues within health systems. A better understanding of how these interventions work in a range of settings and contexts is needed in order to overcome bottlenecks at health system level. To better understand the relationships between implementation and context we developed and implemented an intervention focused on integrating a rapid screening test for syphilis in ANC services in rural primary health care facilities in Burkina Faso. This manuscript describes the intervention and reports on feasibility and acceptability of the intervention, the facilitators and barriers to the implementation of this intervention and the likelihood that point of care test for syphilis will become routinely incorporated in practice. METHODS In Kaya Health and Demographic Surveillance System (Kaya HDSS), all 7 primary healthcare facilities were selected for intervention in 2013. A participatory approach was used to design and implement an antenatal syphilis screening intervention. The Normalization Process Model (NPM) proposed by May et al. was adapted in order to identify barriers and facilitators and to explore the likelihood to become routinely incorporated in practice. Registers, Observations (n = 14 ANC 1) of interactions between patients and health workers during ANC and interviews with health workers (n = 14) were our data sources. RESULTS An intervention that included onsite training, provision of supplies and medicines, quality control and supervision was implemented in 7 health facilities in 2013. Rapid syphilis test and treatment were delivered during ANC within the examination room with no specific additional mechanism regarding staff organization. The perceived barriers were lack of training of all staff, workload, stock-outs of consumables and lack of motivation of staff. Key facilitators included political environment, ease of use of test and acceptability to pregnant women. CONCLUSIONS Onsite testing for antenatal syphilis is a feasible and acceptable intervention in ANC at primary health facility in Burkina Faso. The point-of care test for syphilis is more likely to be acceptable by health workers as routine service and incorporated as a normal practice. TRIAL REGISTRATION The study was retrospectively registered on ClinicalTrials.gov under the Trial Registration Number NCT03156751 .

Abstract
Antenatal care (ANC) represents a delivery platform for a broad range of health services; however, these opportunities are insufficiently utilised. This review explores key barriers and enablers for successful integration of health s"ervices with ANC in different contexts. Data from peer‐reviewed and grey literature were organised using the SURE checklist. We identified 46 reports focusing on integration of HIV, tuberculosis, malaria, syphilis or nutrition services with ANC from Asia, Africa and the Pacific. Perspectives of service users and providers, social and political factors, and health system characteristics (such as resource availability and organisational structures) affected ease of integration. Tweetable abstract Health system factors, context and stakeholders must be considered for integrated antenatal care services.

Abstract
BACKGROUND Each year about two million pregnant women are infected with preventable syphilis infection, mostly in developing countries. Despite the expansion of antenatal syphilis screening programmes over the past few decades, syphilis continues to be a major public health concern in developing countries. Point-of-care syphilis testing may be a useful strategy to substantially prevent syphilis-associated perinatal mortality and other negative consequences in resource-poor settings. However, the evidence on effectiveness has been generated mostly from observational study designs or has been reported as a mixed-intervention effect. OBJECTIVES To assess the effectiveness of antenatal syphilis screening in improving the uptake of screening tests and treatment, and reducing perinatal mortality. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014) and the reference lists of retrieved studies. SELECTION CRITERIA Randomised (individual and cluster) controlled trials comparing different screening tests conducted during routine antenatal check-ups versus no screening test. Cross-over trials and quasi-randomised experimental study designs were not eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked for accuracy. MAIN RESULTS We included two cluster-randomised controlled trials (three reports). Both trials assessed point-of-care syphilis testing with conventional testing methods and together involved a total of 8493 pregnant women. Data from these trials were not amenable to meta-analysis as the measure of effectiveness was assessed in a non-comparable way.One trial randomised 14 antenatal clinics (including 7700 pregnant women) and was carried out at in Ulaanbaatar, Mongolia. The trial assessed one-stop syphilis testing using a rapid treponemal test, and was judged to have unclear methods of random sequence generation, allocation concealment, selective reporting, and other bias and low risk of bias for incomplete outcome data. Blinding was not reported and was assessed as high risk. The point-of-care testing provided screening, test results and treatment within the same day. The trial appears to have adjusted their results to account for clustering. We entered the data into RevMan using the generic inverse variance method. The incidence of congenital syphilis was lower in the clusters receiving on-site screening (adjusted odds ratio (AOR) 0.09, 95% confidence interval (CI) 0.01 to 0.71) and the proportion of women tested for syphilis was higher in the clusters receiving on-site screening at both the first antenatal visit and at the third trimester visit (OR 989.80, 95% CI 16.27 to 60233.05; OR 617.88, 95% CI 13.44 to 28399.01). Adequate treatment and partner treatment was higher with the on-site screening (AOR 10.44, 95% CI 1.00 to 108.99; AOR 18.17, 95% CI 3.23 to 101.20) and more syphilis cases were detected at first and third trimester visits with the on-site screening (AOR 2.45, 95% CI 1.44 to 4.18; AOR 6.27, 95% CI 1.47 to 26.69). Perinatal mortality, incidence of HIV/AIDS, obstacles in uptake of screening, any other adverse effects, or healthcare resource usage were not reported in this trial.The second trial divided clinics into seven matched pairs (including 7618 pregnant women, although results were only presented for the positive cases (793 women)), and within each pair one clinic was randomised to receive the on-site screening and the other to continue routine laboratory testing. The trial was conducted in primary healthcare clinics in KwaZulu-Natal, South Africa. Random sequence generation were judged to be at low risk of bias, but allocation concealment and incomplete outcome data were judged to be high risk. Other bias and selective reporting bias remain unclear. Blinding was not reported and was assessed as high risk of bias. This trial assessed the primary outcome of this review (perinatal mortality) and the secondary outcomes (adverse outcomes; adequate treatment; syphilis prevalence) in the subset of women (793 women) who tested positive for syphilis. Only one outcome, adequate treatment, was adjusted to account for cluster design. However, not enough information was provided to include this in an analysis using the generic inverse variance method. Where possible, results have therefore been presented in forest plots (perinatal mortality; adequate treatment), as if the data are from a parallel randomised controlled trial. These results should therefore be interpreted with caution.The trial reported on perinatal mortality in women with positive test results and showed that on-site screening using a rapid plasma reagin test had no clear evidence of an effect on perinatal mortality reduction (odds ratio (OR) 0.63; 95% CI 0.27 to 1.48; 18/549 (3.3%) versus 8/157 (5.1%)). After loss to follow up, 396/618 (64.1%) women with positive test results received adequate treatment (two or more doses of 2.4 mega units of benzathine penicillin) in the intervention cluster versus 120/175 (68.6%) in the control (OR 0.82; 95% CI 0.57 to 1.17). It was not possible to include any other data on reported outcomes in forest plots (adverse outcomes; syphilis prevalence). Incidence of congenital syphilis, proportion of women test for syphilis, incidence of HIV/AIDS, obstacles in uptake of screening, partner treatment, or healthcare resource usage were not reported in this trial. AUTHORS' CONCLUSIONS This review included evidence from two cluster-randomised trials at high or unclear risk of bias for most of the 'Risk of bias' domains. Data were not combined in meta-analysis because the trials used non-comparable measures of effectiveness.Point-of-care syphilis testing showed some promising results for syphilis detection and treatment rates and for use in different settings. In Mongolia point-of-care testing was found to be effective in increasing the proportion of pregnant women tested for syphilis and treatment provided, reducing congenital syphilis, and improving access to treatment for both women and their partners. In contrast, in rural South Africa, among women with positive test results, there was no clear evidence of an effect of point-of-care syphilis testing in increasing adequate syphilis treatment rates, and reducing perinatal mortality, but point-of-care testing was found to reduce delay in seeking treatment.More trials are therefore warranted to determine the effectiveness of available testing strategies for improving syphilis-associated adverse outcomes in pregnant women and neonates, especially in high-risk regions.

Poor Reporting of Outcomes Beyond Accuracy in Point-of-Care Tests for Syphilis: A Call for a Framework. AIDS Res Treat 2014; 2014:465932. [PMID: 24795821 PMCID: PMC3985157 DOI: 10.1155/2014/465932] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2013] [Revised: 02/23/2014] [Accepted: 02/27/2014] [Indexed: 11/24/2022] Open
Abstract
Background. Point-of-care (POC) diagnostics for syphilis can contribute to epidemic control by offering a timely knowledge of serostatus. Although accuracy data on POC syphilis tests have been widely published, few studies have evaluated broader outcomes beyond accuracy that impact patients and health systems. We comprehensively reviewed evidence and reporting of these implementation research outcomes (IROs), and proposed a framework to improve their quality. Methods. Three reviewers systematically searched 6 electronic databases from 1980 to 2014 for syphilis POC studies reporting IROs. Data were abstracted and findings synthesised narratively. Results. Of 71 studies identified, 38 documented IROs. IROs were subclassified into preference (7), acceptability (15), feasibility (15), barriers and challenges (15), impact (13), and prevalence (23). Using our framework and definitions, a pattern of incomplete documentation, inconsistent definitions, and lack of clarity was identified across all IROs. Conclusion. Although POC screening tests for syphilis were generally favourably evaluated across a range of outcomes, the quality of evidence was compromised by inconsistent definitions, poor methodology, and documentation of outcomes. A framework for standardized reporting of outcomes beyond accuracy was proposed and considered a necessary first step towards an effective implementation of these metrics in POC diagnostics research.

Abstract
OBJECTIVE To estimate the risk of serious adverse reactions to benzathine penicillin in pregnant women for preventing congenital syphilis. METHODS We searched for clinical trials or cohorts that assessed the incidence of serious adverse reactions to benzathine penicillin in pregnant women and the general population (indirect evidence). MEDLINE, EMBASE, Scopus and other databases were searched up to December 2012. The GRADE approach was used to assess quality of evidence. Absolute risks of each study were calculated along with their 95% confidence intervals (95% CI). We employed the DerSimonian and Laird random effects model in the meta-analyses. RESULTS From 2,765 retrieved studies we included 13, representing 3,466,780 patients. The studies that included pregnant women were conducted to demonstrate the effectiveness of benzathine penicillin: no serious adverse reactions were reported among the 1,244 pregnant women included. In the general population, among 2,028,982 patients treated, 4 died from an adverse reaction. The pooled risk of death was virtually zero. Fifty-four cases of anaphylaxis were reported (pooled absolute risk = 0.002%; 95% CI: 0%-0.003% I(2) = 12%). From that estimate, penicillin treatment would be expected to result in an incidence of 0 to 3 cases of anaphylaxis per 100,000 treated. Any adverse reactions were reported in 6,377 patients among 3,465,322 treated with penicillin (pooled absolute risk = 0.169%; 95% CI: 0.073%-0.265% I(2) = 97%). The quality of evidence was very low. CONCLUSION Studies that assessed the risk of serious adverse events due to benzathine penicillin treatment in pregnant women were scarce, but no reports of adverse reactions were found. The incidence of severe adverse outcomes was very low in the general population. The risk of treating pregnant women with benzathine penicillin to prevent congenital syphilis appears very low and does not outweigh its benefits. Further research is needed to improve the quality of evidence.

Abstract
BACKGROUND Syphilis is a major public health problem in many regions of China, with increases in congenital syphilis (CS) cases causing concern. The Chinese Ministry of Health recently announced a comprehensive 10-y national syphilis control plan focusing on averting CS. The decision analytic model presented here quantifies the impact of the planned strategies to determine whether they are likely to meet the goals laid out in the control plan. METHODS AND FINDINGS Our model incorporated data on age-stratified fertility, female adult syphilis cases, and empirical syphilis transmission rates to estimate the number of CS cases associated with prenatal syphilis infection on a yearly basis. Guangdong Province was the focus of this analysis because of the availability of high-quality demographic and public health data. Each model outcome was simulated 1,000 times to incorporate uncertainty in model inputs. The model was validated using data from a CS intervention program among 477,656 women in China. Sensitivity analyses were performed to identify which variables are likely to be most influential in achieving Chinese and international policy goals. Increasing prenatal screening coverage was the single most effective strategy for reducing CS cases. An incremental increase in prenatal screening from the base case of 57% coverage to 95% coverage was associated with 106 (95% CI: 101, 111) CS cases averted per 100,000 live births (58% decrease). The policy strategies laid out in the national plan led to an outcome that fell short of the target, while a four-pronged comprehensive syphilis control strategy consisting of increased prenatal screening coverage, increased treatment completion, earlier prenatal screening, and improved syphilis test characteristics was associated with 157 (95% CI: 154, 160) CS cases averted per 100,000 live births (85% decrease). CONCLUSIONS The Chinese national plan provides a strong foundation for syphilis control, but more comprehensive measures that include earlier and more extensive screening are necessary for reaching policy goals.

Abstract
The Special Programme of Research in Human Reproduction (HRP), co-sponsored by the UNDP, UNFPA, WHO, and the World Bank, is celebrating 40 years of activities with an expansion of its mandate and new co-sponsors. When it began, in 1972, the main focus was on evaluating the acceptability, effectiveness, and safety of existing fertility-regulating methods, as well as developing new, improved modalities for family planning. In 1994, HRP not only made major contributions to the Plan of Action of the International Conference on Population and Development (ICPD); it also broadened its scope of work to include other aspects of health dealing with sexuality and reproduction, adding a specific perspective on gender issues and human rights. In 2002, HRP's mandate was once again broadened to include sexually transmitted infections and HIV/AIDS and in 2003 it was further expanded to research activities on preventing violence against women and its many dire health consequences. Today, the work of the Programme includes research on: the sexual and reproductive health of adolescents, women, and men; maternal and perinatal health; reproductive tract and sexually transmitted infections (including HIV/AIDS); family planning; infertility; unsafe abortion; sexual health; screening for cancer of the cervix in developing countries, and gender and reproductive rights. Additional activities by the Programme have included: fostering international cooperation in the field of human reproduction; the elaboration of WHO's first Global Reproductive Health Strategy; work leading to the inclusion of ICPD's goal 'reproductive health for all by 2015' into the Millennium Development Goal framework; the promotion of critical interagency statements on the public health, legal, and human rights implications of female genital mutilation and gender-biased sex selection. Finally, HRP has been involved in the creation of guidelines and tools, such as the 'Medical eligibility criteria for contraceptive use', the 'Global handbook for family planning providers', the 'Definition of core competencies in primary health care', and designing tools for operationalizing a human rights approach to sexual and reproductive health programmes.

Abstract
OBJECTIVE To examine syphilis testing capacity, screening coverage rates and types of syphilis tests used in medical facilities in southern China. METHODS Eleven of the 14 municipalities in Guangdong province participated. Data on syphilis testing capacity, screening coverage and types of syphilis tests used were collected from all types of public medical facilities offering prenatal care (n = 109). A total of 494 680 women who delivered during 2004-2008 were studied. FINDINGS In 2008, 54 196 pregnant women (43.1%) were not screened for syphilis. Among such women, 32 863 (60.6%) attended clinics without any syphilis testing capacity and 21 333 (39.4%) attended clinics that performed testing but were not screened. The likelihood of not having syphilis test capacity was much higher for hygiene stations (odds ratio, OR: 10; 95% confidence interval, CI: 4-25), services at the township level (OR: 33; 95% CI: 10-100) and services with ≤ 1000 deliveries per year (OR: 1.002; 95% CI: 1.001-1.003). These same service characteristics correlated with lower screening coverage rates (P < 0.01). Only one antenatal clinic had the capacity to conduct both treponemal and non-treponemal tests for diagnosing syphilis. CONCLUSION Syphilis screening is available in very few of the basic medical facilities offering prenatal care where most neonates in southern China are delivered. In light of this and of the increasing incidence of syphilis in the area, expanding point-of-care rapid syphilis testing is a priority.

Abstract
BACKGROUND About 2·1 million pregnant women have active syphilis every year. Without screening and treatment, 69% of these women will have an adverse outcome of pregnancy. The objectives of this study were to review the literature systematically to determine the effectiveness of screening interventions to prevent congenital syphilis and other adverse pregnancy outcomes. METHODS We searched four electronic databases and selected studies to examine evidence for effectiveness of interventions on three outcomes: increased uptake of syphilis testing, increased treatment rates, and reduction in adverse pregnancy outcomes. We used fixed effects meta-analysis to estimate pooled relative risks if no or little evidence of heterogeneity between trials existed. FINDINGS Ten studies met the inclusion criteria, including two randomised trials. Only two studies aimed to encourage women to seek care earlier in pregnancy. Nine studies included decentralisation of screening and treatment. The effects of the interventions on uptake of testing for antenatal syphilis and receiving at least one dose of penicillin were variable and could not be combined statistically. Study interventions were associated with a reduction in perinatal death (pooled risk ratio [RR] from three studies 0·46, 95% CI 0·26-0·82) and stillbirth (pooled RR from three studies 0·42, 95% CI 0·19-0·93). The incidence of congenital syphilis was reduced in all four studies that measured this outcome with heterogeneous results. INTERPRETATION Interventions to improve the coverage and effect of screening programmes for antenatal syphilis could reduce the syphilis-attributable incidence of stillbirth and perinatal death by 50%. The resources required to roll out antenatal screening programmes would be a worthwhile investment for reduction of adverse pregnancy outcomes and improvement of neonatal and child survival. FUNDING None.

Abstract
BACKGROUND Globally syphilis is an important yet preventable cause of stillbirth, neonatal mortality and morbidity. OBJECTIVES This review sought to estimate the effect of detection and treatment of active syphilis in pregnancy with at least 2.4 MU benzathine penicillin (or equivalent) on syphilis-related stillbirths and neonatal mortality. METHODS We conducted a systematic literature review of multiple databases to identify relevant studies. Data were abstracted into standardised tables and the quality of evidence was assessed using adapted GRADE criteria. Where appropriate, meta-analyses were undertaken. RESULTS Moderate quality evidence (3 studies) supports a reduction in the incidence of clinical congenital syphilis of 97% (95% c.i 93 - 98%) with detection and treatment of women with active syphilis in pregnancy with at least 2.4 MU penicillin. The results of meta-analyses suggest that treatment with penicillin is associated with an 82% reduction in stillbirth (95% c.i. 67 - 90%) (8 studies), a 64% reduction in preterm delivery (95% c.i. 53 - 73%) (7 studies) and an 80% reduction in neonatal deaths (95% c.i. 68 - 87%) (5 studies). Although these effect estimates were large and remarkably consistent across studies, few of the studies adjusted for potential confounding factors and thus the overall quality of the evidence was considered low. However, given these large observed effects and a clear biological mechanism for effectiveness the GRADE recommendation is strong. CONCLUSION Detection and appropriate, timely penicillin treatment is a highly effective intervention to reduce adverse syphilis-related pregnancy outcomes. More research is required to identify the most cost-effective strategies for achieving maximum coverage of screening for all pregnant women, and access to treatment if required.
