Active clinical trials for "Chlamydia Infections"

Multicenter clinical study to test a new qualitative in vitro nucleic acid amplification assay based on kPCR technology. The assay is intended for the diagnosis of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC).

Chlamydia trachomatis is the most commonly reported bacterial sexually transmitted infection (STI), especially among young women. Up to 75% of C. trachomatis infected women are asymptomatic. If untreated, C. trachomatis infection can cause sequelae such as pelvic inflammatory disease, ectopic pregnancy and tubal factor infertility. C. trachomatis can also cause anorectal infections, which are typically asymptomatic. Among women with urogenital chlamydial infection, around 36-91% also had concurrent anorectal chlamydial. Notably, there was no association with anal intercourse in the studies that reported it. However, guidelines do not recommend routine anorectal testing, but restricted testing in people who are in high-risk groups, report anal sexual behavior, or have anal symptoms, i.e., on selective indications. This is in contrast to urogenital testing, which is a routine procedure in STI care services. The anal transmission of C. trachomatis in women may occur by autoinoculation from the vagina due to the close proximity of the vagina and the anus. C. trachomatis could lead to a persistent infection in the lower gastrointestinal tract, suggesting the potential role of autoinoculation of cervical chlamydial infection from the rectal site. Such (repeat) urogenital infections could lead to reproductive tract morbidity. Recommended treatments for C. trachomatis infections are a single 1g dose of azithromycin or 100mg of doxycycline 2 times a day for 7 days. Although these two regimens are equivalent for urogenital infection, no study has compared the effectiveness of these two treatments on anorectal infection. If rectal C. trachomatis is a hidden reservoir influencing transmission rates, and considering the potential complications of cervical infections, providing further evidence of the need for effective rectal treatments among women is highly relevant.

Most genital infections by human papillomaviruses (HPV) are asymptomatic or benign and clear within a few months or years. There infections are much less studies than chronic infections, even though they represent the main reservoir for the virus. The goal of this project is to decipher the kinetics of the virus and of the host immune response in acute HPV genital infections in your women. This will be performed by following women longitudinally and regularly in order to measure variations in virus load, immune cell count, cytokine concentration and antibody titers. The investigators will also investigate the interaction between these kinetics and host genetics and host vaginal microbiota

Project Aware introduces a sexually transmitted infection (STI) screening model for sexually experienced adolescents aged 14 to 21 in a large, inner-city Emergency Department (ED) in the Bronx, N.Y. Project Aware will scaffold routine, rapid testing and counseling for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) onto an existing, successful, ED-based HIV testing and counseling program, Project BRIEF. Project Aware will educate and motivate youth to use condoms with the aid of a theory-based, youth-friendly multimedia behavioral intervention proven to be effective during the investigator's K23 training. Through Project Aware, the investigators propose to change the paradigm of STI testing. Whereas a view of "HIV exceptionalism" has persisted in U.S. health policies on STI testing, the investigators propose a comprehensive approach, in which efforts to identify, treat, and prevent multiple STIs coalesce in one program. The research study has two phases. In the production phase, new STI material will be added to the multimedia intervention currently used for HIV education. In the evaluation phase, a randomized controlled trial (RCT) will be conducted to assess the effectiveness of Project Aware in identifying, treating, and preventing new STI infections among high-risk adolescents. The RCT is designed to test the incremental effectiveness of three STI prevention methods: (1) HIV testing and counseling (T&C), (2) HIV T&C and STI testing, and (3) HIV/STI Testing plus a point-of-service risk reduction video that incorporates both HIV and STI counseling and education. The study is powered to examine three STI prevention outcomes: (1) the number of STI infections identified and treated successfully at baseline; (2) the number of new STI infections over the 12 months following study entry, identified by (a) performing STI testing at each follow-up assessment; and (b) obtaining anonymized rate data on STIs reported to the New York City Department of Health; (3) condom use behavior. 600 youth aged 14-21 will be enrolled in the RCT. Youth will be approached in the ED waiting room and recruited by Public Health Advocates. All will complete a survey to screen for eligibility; eligible youth will complete the baseline measures and be randomized. The follow-up data points and measures will be followed at 4, 8 and 12 months (4 time points) and STI testing will be included.

Consenting adult female patient felt by the provider to require gonorrhea/chlamydia endocervical testing will be asked to provide an additional self sample specimen. The specimen will be sent to the laboratory using conventional diagnostic test for gonorrhea/chlamydia.

A Multicentre, controlled, randomized trial of 3 site (urethra, pharynx and rectum) sampling performed every 3 months (3x3) for Neisseria gonorrhoea (Ng)/Chlamydia trachomatis (Ct) screening (comparator) vs. no screening (intervention).

This investigational study will be conducted to evaluate the performance of the NeuMoDx™ CT/NG Assay on the NeuMoDx™ 288 Molecular System and NeuMoDx™ 96 Molecular System (collectively referred to as NeuMoDx™ CT/NG Assay test system).

This is a multi-center study with a minimum of three sites in the United States. The study will enroll approximately 1750 female subjects, 14 years of age and older, and will have a study duration of approximately 9 months after enrollment of the first subject. Female subjects seen at the participating sites for any reason will be evaluated for enrollment in this study. All subjects will be managed per standard of care as applicable. Subjects who are enrolled in the study will perform self-collection of a vaginal swab to be tested by Click device and allow the health care provider (HCP) to collect three additional vaginal swabs to be tested by recognized FDA-cleared comparator methods. Subjects will complete the study in a single visit. The primary objective is to assess the performance of the Click device for detection of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) in self-collected vaginal specimens as compared to Patient Infected Status (PIS) determined by three approved comparator assays using vaginal specimens collected by a qualified HCP in support of obtaining FDA clearance. and a Clinical Laboratory Improvement Amendments (CLIA) Waiver.

The Washington State Community Expedited Partner Therapy Trial is a stepped-wedge community level randomized trial designed to test the hypothesis that a public health program designed to increase the use of expedited partner therapy can decrease the prevalence of chlamydial infection in young women and the incidence of gonorrhea in Washington state. The study intervention will be modeled after and intervention previously evaluated in King County WA (Golden MR, Sex Transm Dis 2007;598-603). The intervention has two components: 1) promotion of patient delivered partner therapy (PDPT) use by medical providers in accordance with Washington state guidelines; and 2) targeted provision of partner services. PDPT use will be promoted through education and by making medication packs for PDPT available statewide. Medical providers will refer selected persons with gonorrhea or chlamydial infection for partner services based on defined criteria associated with failure to ensure partners' treatment. The intervention will be instituted in four waves separated by 6-9 months. Each wave will include approximately 6 local health jurisdictions. The order in which health jurisdictions initiate the intervention will be randomly assigned. The study's primary endpoint will be the prevalence of chlamydial infection in women age 15-25 tested through clinics participating in the state's Infertility Prevention Project (IPP) and the incidence of gonorrhea among women as determined through public health reporting.

This is a randomized controlled trial to determine whether a home screening test for chlamydia and gonorrhea will lead to increased use of screening tests and increased detection of sexually transmitted diseases.
