    Clinical Research Department, Faculty of Infectious and Tropical Diseases, London School of Hygiene & Tropical Medicine, Keppel Street, London, United Kingdom.
    Introduction: The human treponematoses comprise venereal syphilis and the three non-venereal or endemic treponematoses yaws, bejel, and pinta. Serological assays remain the most common diagnostic method for all treponemal infections. Point-of-care tests (POCTs) for syphilis and yaws allow testing without further development of infrastructure in populations where routine laboratory facilities are not available. Read More

    A Nonhuman Primate Model for Rectally Transmitted Syphilis.
    J Infect Dis 2018 Mar;217(7):1139-1144
    Division of HIV/AIDS Prevention, Centers for Disease Control and Prevention, Atlanta, Georgia.
    Among men who have sex with men (MSM), those with a diagnosis of syphilis or other rectal sexually transmitted infections (STIs) are at a higher risk for human immunodeficiency virus acquisition, which is concerning given the large increase in recently reported syphilis cases in the United States. We have developed the first nonhuman primate model for rectally transmitted syphilis by exposing simian/human immunodeficiency virus-infected and naive rhesus macaques to Treponema pallidum in the rectum. All animals showed mucosal lesions, systemic dissemination, and seroconversion (treponemal antibodies). Read More

    Between Colonial, National, and International Medicine: The Case of Bejel.
    Bull Hist Med 2017 ;91(4):744-771
    In the 1920s and 1930s, doctors stationed in the Middle East and North Africa debated whether bejel, a form of endemic syphilis, was an Arab version of syphilis, or a separate disease altogether. Using their clinical experience in the region, they tried to weave this unfamiliar phenomenon into a civilizational narrative, which placed European civilization at the top of a hierarchy. The assumption was that there was something inherent to Islamic societies and their hygienic habits that accounted for this difference. Read More

    From the *Zimbabwe Ministry of Health and Child Care; †Department of Community Medicine, University of Zimbabwe, College of Health Sciences, Harare, Zimbabwe; ‡US Centers for Disease Control and Prevention, Zimbabwe and Division of Global HIV/AIDS, CDC, Atlanta, GA; §Fogarty International Center, National Institutes of Health, Bethesda, MD; ¶Zimbabwe Community Health Intervention Research (ZiCHIRe) Project, Harare, Zimbabwe; ∥Western Sydney Sexual Health Centre, Parramatta; **Marie Bashir Institute for Infectious Diseases and Biosecurity & Sydney Medical School-Westmead, University of Sydney, Sydney, New South Wales, Australia; ††School of Medicine, University of Washington, Seattle, WA; ‡‡Colorado School of Public Health, University of Colorado Denver, Denver, CO; §§Rietmeijer Consulting LLC, Denver, CO.
    Background: In many countries, sexually transmitted infections (STIs) are treated syndromically. Thus, patients diagnosed as having genital ulcer disease (GUD) in Zimbabwe receive a combination of antimicrobials to treat syphilis, chancroid, lymphogranuloma venereum (LGV), and genital herpes. Periodic studies are necessary to assess the current etiology of GUD and assure the appropriateness of current treatment guidelines. Read More

    Factors associated with four atypical cases of congenital syphilis in England, 2016 to 2017: an ecological analysis.
    Euro Surveill 2017 Dec;22(49)
    HIV & STI Department, Public Health England, Colindale, London, United Kingdom.
    Four isolated cases of congenital syphilis born to mothers who screened syphilis negative in the first trimester were identified between March 2016 and January 2017 compared with three cases between 2010 and 2015. The mothers were United Kingdom-born and had no syphilis risk factors. Cases occurred in areas with recent increases in sexually-transmitted syphilis among women and men who have sex with men, some behaviourally bisexual, which may have facilitated bridging between sexual networks.

    Advancing prevention of sexually transmitted infections through point-of-care testing: target product profiles and landscape analysis.
    Sex Transm Infect 2017 12;93(S4):S69-S80
    Department of Reproductive Health and Research, World Health Organization (WHO), Geneva, Switzerland.
    Objectives: Advancing the field of point-of-care testing (POCT) for STIs can rapidly and substantially improve STI control and prevention by providing targeted, essential STI services (case detection and screening). POCT enables definitive diagnosis and appropriate treatment in a single visit and home and community-based testing.

    Methods: Since 2014, the WHO Department of Reproductive Health and Research, in collaboration with technical partners, has completed four landscape analyses of promising diagnostics for use at or near the point of patient care to detect syphilis, , , and the human papillomavirus. Read More

    Assessing stakeholder perceptions of the acceptability and feasibility of national scale-up for a dual HIV/syphilis rapid diagnostic test in Malawi.
    Sex Transm Infect 2017 12;93(S4):S59-S64
    Division of Sexually Transmitted Disease Prevention, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, Centers for Disease Control and Prevention, Atlanta, Georgia, USA.
    Objectives: The WHO recommends pregnant women receive both HIV and syphilis testing at their first antenatal care visit, as untreated maternal infections can lead to severe, adverse pregnancy outcomes. One strategy for increasing testing for both HIV and syphilis is the use of point-of-care (rapid) diagnostic tests that are simple, proven effective and inexpensive. In Malawi, pregnant women routinely receive HIV testing, but only 10% are tested for syphilis at their first antenatal care visit. Read More

    Infectious Diseases Section, Department of Diagnostics and Public Health, University of Verona, Verona, Italy.
    Objectives: The incidence of HIV and syphilis among men who have sex with men (MSM) in Europe has recently increased. Rapid point-of-care tests (POCTs) for syphilis can improve access to screening. The purpose of this study was to evaluate the performance of two syphilis POCTs compared with laboratory tests among MSM. Read More

    Evaluation of seven rapid tests for syphilis available in Brazil using defibrinated plasma panels.
    Sex Transm Infect 2017 12;93(S4):S46-S50
    Department of Surveillance, Prevention and Control of Sexually Transmitted Infections, HIV/AIDS and Viral Hepatitis, Secretariat of Health Surveillance, Ministry of Health, Setor Administrativo Federal Sul, Brasília, Distrito Federal, Brazil.
    Objectives: In 2012, the WHO estimated that 6 million new cases of syphilis per year would occur worldwide, including 937 000 in Brazil. Early diagnosis and treatment of syphilis are essential to reduce morbidity and prevent transmission. The availability of rapid tests (RTs) for this diagnosis means that testing can be performed more quickly, as a point-of-care test, even in non-laboratory environments and requires only simple technical training to antibodies detection.

    Pathogen reduction and blood transfusion safety in Africa: strengths, limitations and challenges of implementation in low-resource settings.
    Vox Sang 2018 Jan 30;113(1):3-12. Epub 2017 Nov 30.
    Department of Pathology, Johns Hopkins University School of Medicine, Baltimore, MD, USA.
    Transfusion-transmitted infection risk remains an enduring challenge to blood safety in Africa. A high background incidence and prevalence of the major transfusion-transmitted infections (TTIs), dependence on high-risk donors to meet demand, suboptimal testing and quality assurance collectively contribute to the increased risk. With few exceptions, donor testing is confined to serological evaluation of human immunodeficiency virus (HIV), hepatitis B and C (HBV and HCV) and syphilis. Read More
