Active clinical trials for "Syphilis"

Global and regional initiatives have been launched for the dual elimination of mother-to-child transmission (MTCT) of HIV and syphilis. As one of the important components in the initiatives, early detection and timely intervention of pregnant women infected with HIV and/or syphilis is critical. In order to improve the number of women tested and treated, innovative strategies are needed. Serologic tests are the diagnostic tests of choice for HIV and syphilis. There are two types of serological tests (treponemal and non-treponemal tests) for diagnosis of syphilis. These generally require venous blood for screening of symptomatic and asymptomatic patients. In addition, these tests are technically demanding, and require laboratory equipment which is not widely available in most resource-limited settings. Recently, Rapid diagnostic tests (RDTs) that can be used at point-of-care for simultaneously detecting antibodies to HIV and syphilis (dual HIV & syphilis treponemalRDTs) using serum/plasma, venous whole blood, or finger-stick whole blood have been developed and are now commercially available. In low-resource settings, a combination of two or three rapid diagnostic tests (RDTs), in which one screening test with a second test to confirm initial positive results or two RDTs in parallel with a third test as a tiebreaker for discordant samples, can be used to diagnose HIV on finger-stick blood. To date, there are few data on the implications of using these RDTs in the antenatal clinic settings, although they have been evaluated in laboratory-based studies and shown encouraging sensitivities and specificities as compared with reference laboratory tests. The objective of this research is to assess the uptake of syphilis testing after the introduction of dual HIV/syphilis rapid testing as compared to single rapid syphilis testing in antenatal clinics in Colombia. The secondary objectives of the study are: To determine the uptake of treatment of syphilis after the intervention, To determine the uptake of HIV testing in ANC attendees after the intervention, To explore the acceptability of dual HIV/syphilis RDTs by ANC attendees and health workers, To assess the organizational and socio-cultural advantages and barriers to introduction with a aim of sustainable adoption of dual HIV/syphilis RDTs in antenatal services, To determine the workload and cost implications of introduction of dual HIV/syphilis RDTs in antenatal services

During the winter of 2007, the Syphilis Advisory Group and Bureau of STD Control of the NYC Department of Health funded the Emergency Department of Jacobi Medical Center to further evaluate the effectiveness of the Syphilis and Men video in additional settings where men access STD related information and testing and where high-risk groups, such as MSM, frequent. The video was evaluated for promoting knowledge of syphilis, especially as facilitator of HIV transmission, and in encouraging concurrent testing (syphilis and HIV) among men recruited from a community-based organization, an ambulatory care setting, and a dance club.

The objective of this study is to determine whether the "Syphilis and Men" educational video can be a useful tool to increase syphilis knowledge and testing among English and Spanish-speaking urgent care and emergency department patients, regardless of various self-reported characteristics that increase their risk for syphilis infection.

Circumcision in HIV unifected men may reduce the likelihood of becoming infected with HIV, reduce sexually transmitted infections (STIs) in men, not engender increases in sexual risk behaviors, and be acceptable to men as a procedure for preventing HIV. The purpose of this study is to evaluate circumcision in HIV uninfected men in terms of safety and ability to prevent HIV infection.

Nearly 1.5 million pregnant women are infected with syphilis each year, and it is estimated that half of them will have adverse birth outcomes. Congenital syphilis remains a major public health issue, despite the fact that maternal syphilis is easy to detect and treat. Multiple barriers impair the elimination of congenital syphilis. Syphilis is often stigmatized and of low priority, and even women attending prenatal care early are potentially facing multiple clinical barriers. The study objective is to use implementation research methods to evaluate a multifaceted intervention to increase the use of evidence-based clinical procedures to prevent congenital syphilis. The investigators will perform a facility-based, two-arm parallel cluster randomized implementation trial in the Democratic Republic of the Congo and Zambia. The intervention will be multifaceted, tailored by formative research, and include: opinion leaders, reminders, monitoring, and feedback; point-of-care rapid tests; and treatment kits to be used immediately if the rapid test is positive. Improving syphilis screening and treatment will be promoted as a key step toward improving the quality of all components of prenatal care.

This pilot study will investigate the feasibility of conducting a large, randomized trial comparing a structural intervention to contingency management to reduce incident syphilis infections in an especially high risk group: HIV+ men who have sex with men (MSM) who have had syphilis twice or more since their HIV diagnosis. Subjects will be randomized to receive either QD doxycycline as syphilis prophylaxis or a financial incentive to remain STI free. The investigators will : 1) measure adherence to study visits in both arms; 2) measure adherence to the prophylaxis regimen; 3) measure any changes in risk behaviors among study participants and 4) to the extent possible in a small pilot study of short duration, compare effectiveness of doxycycline with that of a monetary incentive for remaining STI free.

The primary aims of the study were to assess the safety and acceptability of Carraguard applied vaginally prior to sexual intercourse for six months in both women and men; and to examine several dimensions of acceptability. Secondary aims were to gauge reactions to a non-contraceptive microbicide, to assess use dynamics among Thai couples and to observe preliminary indications of sexually transmitted infections and reproductive tract infections averted. The hypothesis was that Carraguard would cause little or no significant irritation, including lesions; and that women and men would find Carraguard acceptable.

The primary aims of the study were to assess the safety and acceptability of PC-515 when applied vaginally at least three times weekly for 12 months. Secondary aims were to gather preliminary data on Carraguard's effectiveness in preventing male-to-female transmission of HIV, and other STIs. The hypothesis was that Carraguard would cause little or no significant irritation, including lesions; and that women would find Carraguard acceptable. The study was not powered to determine effectiveness, but based on safety, acceptability and feasibility parameters, the outcome of the Phase 2 trial would enable a decision whether or not to proceed to a Phase 3 trial.

This project seeks to determine the personal and organizational conditions that are most conducive to the widespread adoption by community-based organizations (CBOs) of effective programs for reducing the spread of HIV and other sexually transmitted infections (STIs). Taking a brief, single-session counseling program (called "Mujer Segura") that has been proven effective in reducing HIV and STIs in female sex workers who work in Mexican cities along the U.S. border, this project will study the implementation of the program in CBOs in 12 additional cities throughout Mexico to determine how best to ensure that the program remains true to the original model and retains its effectiveness. Mexico has been chosen because HIV is a global problem that respects no international borders, and because HIV prevention programs that can be implemented in settings with limited resources are urgently needed in many parts of the world.
