Filter by: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.

The present trial is a phase I first in human, double blind, parallel and placebo controlled trial of SSI's adjuvanted chlamydia vaccine CTH522: CTH522-CAF01 (CAF01 is an adjuvant system) and CTH522-Al(OH)3. The trial will be conducted at Imperial College Research site in the United Kingdom. Subjects are randomly assigned to one of the following three treatment groups in a ratio of 3:3:1. This trial consisted of 10 visits and 5 telephonic interviews
The proposed study is a randomized controlled trial (RCT) that will rigorously evaluate the effectiveness and cost-effectiveness of delivering a multimedia evidence-based intervention (WORTH) and streamlined HIV testing to prevent human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) with Black/African-American (hereafter referred to as Black) women drug users in probation sites in New York City (NYC), compared to streamlined HIV testing alone. Repeated assessments will occur at baseline and 3, 6, and 12-months post intervention. The primary outcomes will be to reduce cumulative incidence of biologically confirmed STIs (i.e., Chlamydia, gonorrhea and trichomonas and the number of unprotected sex acts.
The objective of this project is to assess the impact of a Game-Based Appointment System on both, the clinical settings, and on the use of the educational web app www.sjekkdeg.no. An A/B testing methodology will be used. This methodology consist on the redirection of the users to two different versions of the website, and therefore allows to assess the interactivity of the users according to the design of the webpage and determine which one has a higher impact on the clinical settings, and consequently on prevention of STDs. For the A/B test we will test the interactivity of two versions of a web page www.sjekkdeg.no: the A version (control), consisting en the educative web app; and the B version, consisting in the web app www.sjekkdeg.no including the Game-Based Appointment System. The Game-Based Appointment System will offer the users the option of booking appointments at the venereology department at the University Hospital of North Norway. The system will include an automatic priority appointments function, with three levels of prioritization (triage): 1) Emergency-appointment: The user should go to the doctor on the same day or the following day. 2) Haste-appointment: Within 3-4 days; or 3) Routine-appointment: within 2-3 weeks. The hypotheses of this research project are: 1. The number of visits with the health professionals will be larger in the game-based appointment group than in the control group. 2. The number of visits to the educative components of www.sjekkdeg.no will increase after the launch of the Game-Based Appointment System functionality. 3. The number of visits to the educative components of www.sjekkdeg.no will be larger in the appointment group than in the control group. 4. The time spent per visit to the website will be larger in the appointment group than in the control group, meaning a higher exposure to health information. 5. The visitors returning rate is larger in the appointment group than in the control group.
The objectives of this study are to establish the performance characteristics of the AC2 (APTIMA Combo 2) Assay on the PANTHER System for the sample types cleared for use on the TIGRIS and DTS (Direct Tube Sampling) Systems and to demonstrate the repeatability and reproducibility of the AC2 Assay on the PANTHER System.
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.
In the early years of the HIV epidemic in Africa, female sex workers (FSWs) were identified as a high-prevalence, high-incidence, core group among whom the extraordinary prevalence of other sexually transmitted infections (STIs) facilitated transmission of the virus to their clients, who then infected low-risk women not involved in the sex trade. In resource-poor settings, control of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) among FSWs is difficult. The purpose of this study is to determine whether periodical antibiotic treatment (PAT) is effective in controlling these infections among West African FSWs. The study is designed as a cluster-randomized double-blind placebo-controlled trial conducted in West Africa. The study population consists of "seaters" FSWs who work from their homes in well-defined areas. Clusters will be paired according to their size and demographic characteristics of FSWs and clients. Within each pair, one cluster will be randomly allocated to the intervention and the other to the placebo group. At enrollment, participants will be interviewed, a pelvic examination performed, cervical swabs obtained for NG and CT polymerase chain reaction (PCR), and current cervicitis or vaginitis managed syndromically. Blood specimens will be obtained for HIV testing. All participants will be given free condoms and counseled on risk reduction. Monthly follow-up will be conducted within FSW communities, alternating with clinic visits where cervical samples will be collected. Study drugs (azithromycin 1 g and ciprofloxacin 500 mg, and their identical placebos) will be distributed every month according to a predefined schedule: directly-observed intake of azithromycin at months 1, 4 and 7, and ciprofloxacin at months 2, 3, 5, 6, 8 and 9. Data will be analyzed with SAS. The investigators will assess the time trends in NG and CT prevalence separately in both study groups using χ2-for-trend.
The purpose of this study is to determine the prevalence and treatment rates of T. vaginalis, C. trachomatis, and N. gonorrhoeae in women seeking emergency contraception or urine pregnancy testing in the Magee-Womens Hospital outpatient clinic using a non-invasive urine STD test.
There has been an increase in incidence in sexually transmitted infections in HIV infected patients in the last years. In this study the investigators will prospectively evaluate the prevalence of symptomatic and asymptomatic infections with N. gonorrhea and Ch. trachomatis as well as the seroprevalence of Herpes simplex Type 2 infection in HIV-infected patients attending the clinic for infectious diseases at the Berne University Hospital. In addition, participants will be asked to fill out a questionnaire on sexual behaviour and sexual health. Study hypothesis: STI prevalence is high in certain risk-groups to justify screening in regular intervals.
