Filter by:In 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.
Treponema pallidum is a bacterium that causes the disease syphilis. The primary objective of the study is to evaluate the testing performance of two diagnostic molecular techniques [quantitative polymerase chain reaction (qPCR) and transcription-mediated amplification (TMA)] for the detection of Treponema pallidum in maternal and neonatal specimens from participants with the diagnosis of syphilis using the Centers for Disease Control's (CDC's) Sexually Transmitted Infections (STI) Treatment Guidelines for adult and congenital syphilis.
This randomized controlled superiority study will be conducted during 2023-2025. The eligible participants are adult people living with HIV (PLWH) who are newly diagnosed with early syphilis. Participants will be randomized in a 1:1 ratio to receive single-dose benzathine penicillin G (BPG) (2.4 MU intramuscularly once) plus doxycycline (100 mg orally twice daily for 7 days) or single-dose BPG. The primary outcome is serologic response, defined as a decline of rapid plasma reagin (RPR) titer by 4-fold or greater, at week 24 and week 48; and the secondary outcomes include microbiologic response of syphilis and bacterial sexually transmitted infections (STIs) assessed by nucleic-acid amplification test (NAAT) at week 4.
Men who have sex with men (MSM), especially young men who have sex with men (YMSM), and transgender women (TGW) have some of the highest rates of HIV and syphilis diagnoses in the United States. The goal of this study is to pilot the mobile Lab (mLab) App Plus to assess YMSM's and YTGW's abilities to perform and interpret self-tests for HIV and syphilis and consequently increase the number of YMSM and young transgender woman (YTGW) who initiate self-testing for HIV and syphilis.
Elimination 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.
In a prospective study investigating the prevalence of STIs among at-risk PLWH, the prevalence of Chlamydia trachomatis and N. gonorrhoeae was 24.7% and 12.1%, respectively. Surprisingly, the study found high rates of C. trachomatis and/or N. gonorrhoeae co-infections in PLWH with recent hepatitis C virus (HCV) infection (50%), HBsAg positivity (44%), and early syphilis (36%). Considering the high rate of sexually transmitted co-infections, combination therapy of single-dose ceftriaxone plus 7-day doxycycline for early syphilis may provide convenience and benefit to treatment of N. gonorrhoeae and C. trachomatis co-infections at a single clinic encounter. In the present study, this study aim to compare the efficacy of ceftriaxone plus doxycycline versus BPG plus doxycycline as the treatment for early syphilis among PLWH.
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.
The 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 5 in The Gambia. The TRI-MOM program has two components: 1. 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. 2. an "evaluation" component which will assess the impact of the TRI-MOM strategy on PMTCT services, reduction of HBV MTCT and women empowerment.
The goal of this clinical trial is to learn about Syphilis and HIV point of care testing among inner city, remote, rural and hard to reach populations in Saskatchewan. The main question[s] it aims to answer are: 1. To evaluate the field diagnostic test performance (e.g. sensitivity, specificity, predictive values) of finger prick whole blood point of care testing (POCT) when compared to standard serum based testing for syphilis POCT, HIV POCT and dual syphilis and HIV POCT. 2. To evaluate the clinical utility of POCT for the prompt management and public health follow up of syphilis and HIV cases as compared to usual testing, specifically: 1. Time to diagnosis 2. Time to treatment 3. Number of contacts exposed to untreated infections 4. For HIV diagnoses, time to connection to clinical provider for ongoing management of HIV 3. To evaluate the acceptability and feasibility of POCT among different populations for syphilis and HIV among at risk and/or hard to reach populations, specifically: 1. Health care provider experiences of feasibility and acceptability of the POCT used in this pilot 2. Client acceptability and experiences with POCT in this pilot 3. Client preferences for test offered (syphilis only, HIV only, or dual test of HIV and syphilis 4. To evaluate the acceptability and feasibility of syphilis alone, HIV alone or combined syphilis/HIV POCT among at-risk and/or hard to reach populations. Participants will be assessed for risk factors that may increase risk of infectious disease such as substance use and sexual habits. They will then be offered a choice of 1 of 3 POCT(Syphilis alone, HIV alone or a dual HIV/Syphilis test). Serology will be obtained for sexually transmitted and blood born infections (STBBI's) and then the point of care test (POCT) will be completed. Following the testing the participant will complete a short survey on their experience.
This study is to test the Reveal® TP (Syphilis) antibody POCT (MedMira, Inc., Halifax, Nova Scotia) for its performance in an urban STI clinic in Vancouver, British Columbia and compare its performance in parallel with the usual testing method (the gold standard).
