Active clinical trials for "Gonorrhea"

This study aims to compare the sensitivity of detecting Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium by real-time multiplex PCR in a pooled analysis (i.e. gathering pharyngeal, anorectal and urinary samples) versus the standard of care (where a real-time multiplex PCR is made in each of the three samples).

This study, named "Check it," is a bundled program for African American (AA) men ages 15-24 that includes community testing for chlamydia and gonorrhea, expedited treatment for subjects who test positive and their female sexual contacts, and rescreening for these two sexually transmitted infections.

The purpose of this study is to determine if an Audio-enhanced Computer-Assisted Self-Interview (ACASI) will lead to increase testing for sexually transmitted infections in youth visiting a pediatric ED

This is a Phase 1, interventional, non-randomized, experimental infection model study with healthy adult males adults (N=32) between the ages of 18-36 at study enrollment. The study is designed to test the requirements of predicted N. gonorrhoeae virulence determinants for gonococcal infection in the male urethra. The duration for all participants will be about 3 weeks. Study duration will be approximately about 18 months for implementation and enrollment. The primary objectives of the present study are to: (1) compare infectivity of different isogenic mutants with wild-type (WT) N. gonorrhoeae in noncompetitive infections and to (2) assess relative fitness of the mutant in competitive infections initiated by inocula containing equivalent numbers of both WT and mutant strains for mutants with WT infectivity.

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.

The purpose of this study was to use participant samples to simultaneously evaluate three nucleic acid amplification tests (NAATs) diagnostic platforms.

This randomized controlled trial conducted in Rakai District, Uganda, has enrolled 997 HIV positive men and 500 men who declined to learn HIV results (regardless of HIV status). The hypotheses are that male circumcision will be acceptable to and safe in both groups and will reduce the rates of STD acquisition in both groups and of HIV acquisition in HIV-negative men. Enrollment was ended on Dec 12, 2006, following an interim Data Monitoring and Safety Board (DSMB) review of a closed report. At that time the DSMB determined that futility with respect to the female HIV outcome. There was an non-significantly higher rate of HIV acquisition in women partners of HIV+ men in couples who had resumed sex prior to certified post-surgical wound healing. The data indicated significant reductions (~50%) in GUD symptoms among circumcised HIV+ men. The DSMB recommended: 1) that men and women should continue to be followed in complete two year follow up on all, 2) that circumcision for remaining HIV+ intervention arm men and for control arm men who had completed their 2 year follow should continue, contingent on a) revision of the study protocol to add additional post-surgical visits to assess wound healing, b) protocol revision to further strengthen education for both male and female partners on the need to postpone sex until certified wound healing, and c) approval of the revised protocol by the IRBs in both the US and Uganda. 3) An additional follow up visit for women be instituted at 18 months after enrollment. Protocol revision and IRB approvals have been finalized in June, 2007. The study has also enrolled and is following 3,700 women sexual partners of men enrolled in this study and in a complementary National Institutes of Health (NIH) funded study (U1 AI51171 which is separately registered). The hypotheses are that male circumcision will be acceptable to and safe in women partners, and will reduce the women's acquisition of HIV and STDs such as herpes simplex virus-2 (HSV-2) and human papillomavirus (HPV).

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.

The objective of this study is to obtain female first-catch urine, vaginal, cervical and endocervical swabs for testing with multiple APTIMA Assays on the Gen-Probe PANTHER® and TIGRIS® Systems.

Julius Schachter, PhD, (Department of Laboratory Medicine, University of California, San Francisco) and Susan S. Philip, MD MPH (Department of Medicine, University of California, San Francisco) are conducting a study to evaluate the Abbott RealTime CT/NG polymerase chain reaction [PCR] assay (which is a nucleic acid amplification test [NAAT]) for detecting two sexually transmitted bacteria, Chlamydia trachomatis [CT] and Neisseria gonorrhoeae [NG], using urine samples and swabs from the throat and rectum of men who have sex with men [MSM]. Using this test on these swabs is experimental because it has not been approved by the Food & Drug Administration.
