Filter by:A retrospective national epidemiological Swiss study was conducted to establish a real prevalence and description of congenital syphilis, and to better classify the reported congenital syphilis. Maternal risk factors to contract syphilis (i.e. socio-demographic, cultural and clinical factors) were also evaluated, in order to focus on prevention of these targeted population. Follow up of the children born from mother with syphilis during pregnancy, until age 6, was recorded to evaluate the risk of congenital syphilis following treatment of maternal syphilis.
This is a prospective cohort study evaluating acceptability, feasibility, and effectiveness of integrating HIV pre-exposure prophylaxis (PrEP) into a sexually transmitted infection (STI) clinic alongside assisted partner notification and etiologic STI testing in Lilongwe, Malawi.
This study is designed to compare the performance of the NOWDx Syphilis Test to a currently marketed device. The intent is to show the rapid test device is comparable to the currently marketed device. The NOWDx Syphilis Test is intended for qualitatively detecting the presence or absence of human antibodies to syphilis in human whole blood to aid in the diagnosis of infection caused by Treponema pallidum.
This study will evaluate the performance of two point-of-care dual syphilis and HIV tests [Multiplo TP/HIV test (MedMira Inc, Halifax, Nova Scotia) and the INSTI Multiplex HIV-1/HIV-2/Syphilis Antibody Test (bioLytical Laboratories Inc., Richmond, BC)]. In addition to standard syphilis and HIV testing, point-of care testing (POCT) will be performed on 1,500 consecutive participants who are being screened for syphilis and HIV and who are at least 16 years old. POCT will be conducted using a fingerprick whole blood specimen. The study will be conducted at multiple sites in Northern Alberta (Canada), a region which is currently experiencing a resurgence of infectious syphilis.
Syphilis infection is a major global health problem, leading to substantial morbidity among key populations in low- and middle-income countries (LMICs). Men who have sex with men (MSM) are disproportionately affected by syphilis worldwide. Rates of syphilis diagnoses have been increasing amongst MSM in many countries in the last decade. A growing evidence base supporting HIV self-testing shows that self-testing kits based on the same proposed clinical pathways are feasible and reliable. The proposed study will leverage this body of evidence and apply it to syphilis self-testing. This is a pilot study conducted in Zimbabwe. It aims to collect initial data on the feasability of implementing syphilis self-testing to establish if a large scale-RCT of this approach would be appropriate and, if so, to inform the design of this trial. The investigators will recruit 100 MSM in Harare to join the pilot program. Participants will be recruited through two methods: in-person at MSM community-based organizations that currently operate HIV self-testing programs and online through banner advertisements that advertise HIV self-testing. Study Arms: Arm 1: One arm of the pilot will receive a free syphilis self-test kit (Intervention Arm) Arm 2: One arm will receive standard free facility-based syphilis testing (Control Arm). Intervention: In the intervention arm the investigators will provide a treponemal rapid syphilis test kit to all participants in the intervention arm of the pilot, delivered through MSM community facilitators. This is similar to existing rapid treponemal test kits that are available at many clinical facilities. Kits will be accompanied by simplified pictorial instructions on finger prick blood sample collection. Among participants in the control group, they will receive a list of local clinics that can provide free syphilis testing. Data Collection: For individuals in the intervention am the investigators will aim to obtain confirmation of test uptake. This will be done using either photographic confirmation sent via encrypted message on a smartphone, SMS message of a unique code or sending a unique five-digit code along with their test result to the study coordinator. The investigators will conduct cross-sectional surveys at baseline and six months later to assess sexual risk behaviours, HIV and syphilis testing experiences, and self-testing experiences. In addition to the survey data tool the investigators will conduct in-depth interviews with a small number of participants to gain additional data about their experience of syphilis self-testing. The investigators will obtain information on linkage to care from routine clinic administrative records and by providing study participants with a unique code to be provided when attending at the facility. Analysis: The investigators will used mixed-methods to evaluate our pilot intervention including The investigators will examine the proportion of individuals who undertake a syphilis test in the interventional and control arms; among those who receive a test, the proportion of individuals who receive appropriate post-testing services. The investigators will also collect qualitative data on attitudes to syphilis self-testing and quantitative data on syphilis prevalence to inform a subsequent clinical trial.
Syphilis is classically described as a sexually transmitted disease. As this source of contagious has been described long ago -mainly though by observation- when children presents with acquired syphilis, child abuse is always considered and must be ruled out by specialists in a careful evaluation. However, muco-cutaneous lesions can be a contagious source for congenital syphilis; therefore the possibility of non-sexual transmission through intimate contact with infected people through humid lesions (such as in kisses, breastfeeding, food-handling) or contaminated fomites (towels, bed sheets, underwear, cups, pacifiers, cutlery) could be considered. Experts worldwide have observed this non-sexual transmission, as described in many reports in literature. The investigators will study retrospectively patients from a cohort with non-sexual transmission. The diagnosis criteria used for acquired syphilis were as follows: age under 18 years with treponemic and nontreponemic positive tests, secondary-syphilis suspicious lesions and negative maternal syphilis serology. Nonsexual contagious was defined as contacts without physical and psychosocial indicators of sexual abuse according to current guides. In this cohort, in every case a psychosocial evaluation was completed with a written report in order to evaluate sexual contact probability. The teamo will describe these patients clinical and laboratory findings, family and close acquaintances serologies and probable source of contagious.
The investigators study the behavioral consequences of Pre-exposure Prophylaxis or PrEP on sexual health behaviors, sexual health outcomes, and partner selection preferences. The study collects observational, self-reported data on PrEP status, PrEP taking-history, PrEP adherence over the last 30 days, STD diagnosis history dating back to January 2015 up to December 2019, sexual health behaviors (e.g., positioning, number of lifetime/recent partners, condom adherence etc.), and various demographic characteristics. The survey finishes with a conjoint experiment which asks respondents to select between two potential partners, and follow-up question about each profiles. Potential partners' characteristics include recreational drug use and condom adherence. Recruitment is conducted via running an ad on Facebook in New York, London, Toronto and Sydney for comparative purposes, as these metro areas have varying levels of PrEP use and accessibility.
Syphilis is an infectious disease caused by Treponema pallidum. In children, there are two different forms of this disease; acquired syphilis and congenital syphilis, which results from transplacental transmission of spirochetes. The worldwide incidence of congenital syphilis has increased in past years, probably due to inadequate control of pregnant women and lack of early diagnose and treatment in acute infected adults. This infection can have numerous and non-specific manifestations at all stages, and may simulate other diseases, which can delay diagnose if not suspected. A high number of newborns can be asymptomatic, so diagnose is confirmed or discharged by serologic testing after 6 to 10 months of age. This study will observe the clinical presentation and the laboratory of patients with CS treated.
Syphilis is an important sexually transmitted infection. There has been an epidemic of syphilis amongst men who have sex with men in the United Kingdom in the last decade. Early infection with syphilis causes a genital ulcer followed, in the absence of treatment, by a generalised illness often accompanied by rash. Studies on syphilis have been limited because it is not possible to grow syphilis outside of the body. New approaches allow the whole genetic sequence of Treponema pallidum to be obtained from a swab. In this study residual DNA collected as part of routine patient care of patients seen at sexual health clinics in the UK will be used for sequencing. No patient contact is involved in the study which is limited to whole genome sequencing using residual material from samples. By better understanding the genome of the T.pallidum insights will be gained in to the pathogenesis of this important sexually transmitted disease.
The goal of the study is to evaluate the efficacy of oral cefixime as an alternative treatment for syphilis infection. One hundred adult patients (≥18 years old) with syphilis infection (positive Treponema Pallidum Particle Agglutination assay and RPR titer ≥ 1/8) will be recruited. Participants will be randomized (1:1) to receive either the standard of care Penicillin or Cefixime. During the study, participants will visit the clinic up to 5 times; at baseline visit, at 3, 6, 12 months after treatment initiation. Participants of the cefixime group will be required to visit the clinic 14 days after treatment initiation. In each visit, participants will be asked about current symptoms and do laboratory tests for syphilis (RPR). Subjects who have a 4-fold decrease (from study entry RPR) in RPR titers from baseline at 6 months will be considered a positive treatment response.
