Oral Doxycycline for the Prevention of Syphilis in Men Who Have Sex With Men (DaDHS)
SyphilisSexually Transmitted InfectionsSyphilis is a sexually transmitted infection (STI) disproportionately affecting gay, bisexual and other men who have sex with men (gbMSM), with the potential for significant sequelae - particularly in those who are Human Immunodeficiency Virus (HIV)-positive. Rising rates of this STI have prompted a search for novel prevention solutions. A recent pilot study of daily doxycycline prophylaxis demonstrated promise as a novel STI prevention tool. This innovative approach to STI prevention has solid clinical precedent, both from the HIV pre-exposure prophylaxis (PrEP) literature, as well as doxycycline's use as prophylaxis for other infections. The overarching goal of this project is to determine whether the daily use of doxycycline is an efficacious and acceptable intervention for syphilis prevention in high-risk, HIV-positive gbMSM.

MENJAGA: Continuous Quality Improvement for Antenatal HIV, Syphilis and Hepatitis B Testing in Indonesia...
HivSyphilis1 moreElimination of mother-to-child-transmission (EMTCT) of HIV, syphilis and hepatitis B are key priorities in Indonesia, the fourth most populous country in the world. Despite national guidelines and strong antenatal care attendance, coverage of antenatal screening for these diseases among pregnant women remains extremely limited in Indonesia. The Indonesian government is committed to improving the integration of HIV/syphilis/hepatitis B testing and treatment into the antenatal platform but currently lacks comprehensive evidence on interventions to support this. We will evaluate a low-cost and locally driven intervention based on the principles of continuous quality improvement to strengthen antenatal care and promote screening for HIV, syphilis and hepatitis B. Continuous Quality Improvement (CQI), which involves local antenatal care (ANC) teams systematically collecting and reflecting on local data to inform the design and implementation of service delivery, has been effectively used to strengthen ANC in a number of Sub-Saharan African countries but yet to be comprehensively evaluated in ANC services in Indonesia. This approach holds considerable promise for Indonesia, a highly populous and diverse country where a 'one size fits all' approach to the delivery of quality ANC rarely applies.
The TRIple Elimination Model Of Mother-to-child Transmission Program (TRI-MOM)
HivSyphilis1 moreThe TRI-MOM program aims to implement and evaluate a simplified (based on inexpensive rapid diagnostic tests), integrated (in governmental health facilities) and coordinated (between health care workers) strategy for the triple elimination of HIV, syphilis and HBV mother-to-child transmission (MTCT) in nine maternal and child health services, 5 in Burkina Faso and 4 in The Gambia. The TRI-MOM program has two components: an "intervention" component consisting of a pilot study to reinforce the antenatal screening and prevention of MTCT (PMTCT) capacities for the 3 targeted infections through the implementation of a simplified, integrated and coordinated strategy of triple elimination of MTCT. an "evaluation" component which will assess the impact of the TRI-MOM strategy on PMTCT services, reduction of HBV MTCT and women empowerment.
Zenyth: Motivational Interviewing-based Telehealth Intervention for Bacterial Sexually Transmitted...
Sexually Transmitted DiseasesGonorrhea3 moreIn the United States (US), gay and bisexual men living with human immunodeficiency virus (HIV) bear a heavy burden of bacterial sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and syphilis. It is important to diagnose and treat STIs in a timely manner to prevent health complications and reduce transmissions. The purpose of this study is to understand whether gay and bisexual men living with HIV are willing to collect and return specimens for bacterial STI testing when combined with live audio/video (AV) conferencing support.
Impact of the Daily Doxycycline Pre-exposure Prophylaxis (PrEP) on the Incidence of Syphilis, Gonorrhoea...
STIs Prevention1. This study is a non-randomized observational cohort trial using before and after comparison to evaluate intervention 2. It would mimic the conditions that would occur outside a clinical trial. 2. After consent and enrolment, all procedures will be guided by the Australian STI Management Guidelines. 3. All enrolling participants will be offered daily doxycycline 100mg 4. All participants will be invited to complete a survey in every 3 months time for 12 months dated from participation. 5. All follow-up information will be collected through electronic data capture to allow accurate and timely analyses. 6. Data collection will be from (i) medical records (ii) online self-completed questionnaire
Cefixime for Alternative Syphilis Treatment
SyphilisEarly SyphilisThe 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.
Phase 4 Comparative Trial of Benzathine Penicillin G for Treatment of Early Syphilis in Subjects...
SyphilisThis is a phase 4, randomized, open-label, multicenter trial to evaluate the efficacy of a single injected dose of Benzathine Penicillin G (BPG) 2.4 MU (Arm 1) compared to three successive weekly injected doses of BPG 2.4 MU (Arm 2) for treatment of early syphilis in human immunodeficiency virus (HIV)-infected and HIV-uninfected subjects. The study will enroll 560 adults (to achieve 420 evaluable subjects) aged 18 years or older with untreated early syphilis (primary, secondary, or early latent). It will be conducted at 9 sites in the US and last for 48 months with patient participation duration of 12 months. The primary objective is to compare the serological response to therapy in subjects with early (primary, secondary, or early latent) syphilis treated with Benzathine Penicillin G (BPG) 2.4 million units (MU) once or weekly for three successive weeks.
Azithromycin/Bicillin Syphilis
SyphilisThe purpose of this study is to determine if azithromycin, a drug approved for treatment of other infections, is as effective for syphilis (a sexually transmitted disease) as the standard treatment. Approximately 600 healthy adults, who are HIV-negative, ages 18 to 55 years of age, with primary, secondary or early latent syphilis, will participate in this research study. Volunteers will be enrolled in 5 U.S. cities and in Madagascar. Participants will be chosen randomly (by chance) to receive 1 of 2 study drugs: benzathine penicillin given (2 shots in the buttocks) or 4 tablets of azithromycin. Subjects who report a history of a penicillin allergy will be given either 2.0 g of oral azithromycin or 100 mg doxycycline taken orally, twice a day for 14 days. Over 2 years, 10 visits will be required. Procedures will include blood samples, physical exams, and swabs of sores.
