Active clinical trials for "Chlamydia Infections"

The investigators propose to develop and pilot an HIV prevention intervention based on rectal STI testing, counseling, and treatment for MSM in Peru. The investigators will use nucleic acid testing to screen 750 behaviorally high-risk MSM for rectal gonorrheal and/or chlamydial (GC/CT) infection. GC/CT-positive subjects will receive single-dose antibiotic treatment and single-session Personal Cognitive Counseling (PCC) (n=50) or standard post-test counseling (n=50). A GC/CT-negative control group (n=50) will also be enrolled to compare biological outcomes including changes in levels of inflammatory cytokines following rectal STI. The intervention is based on three interrelated objectives: 1) To use periodic rectal STI nucleic acid testing to identify the members of the MSM population at greatest short-term risk for HIV infection; 2) To provide single-dose antibiotic treatment to control the immune activation and mucosal inflammation caused by rectal GC/CT infection that increase cellular risk for HIV transmission; and 3) To use Personal Cognitive Counseling (PCC) to understand and modify recent high-risk sexual practices that led to rectal STI acquisition and that increase future HIV risk. The investigators propose to screen 750 behaviorally high-risk MSM for rectal GC/CT infection to enroll 100 GC/CT-positive individuals (using a conservative 15% prevalence estimate) and 50 GC/CT-negative controls (matched by age and baseline frequency of URAI). GC/CT-infected participants will be given single-dose antibiotic therapy and randomized to receive single-session PCC (n=50) or standard post-test counseling (n=50). The primary outcome will be the impact of PCC on self-reported sexual risk behavior (URAI). Secondary outcomes will assess: 1) Feasibility/Acceptability of the STI screening program; 2) Impact of GC/CT infection and treatment on levels of inflammatory cytokines (IL-6, IL-8, TNF-αand IL-1β) in rectal mucosa; 3) Prevalence of persistent/recurrent rectal GC/CT; and 4) HIV incidence in GC/CT-infected and -uninfected MSM.

This study tests a 12-episode Internet-based, guide enhanced Love, Sex, & Choices (LSC) HIV prevention soap opera video series for smartphones or computers, in a randomized clinical trial among predominately at-risk African American urban women. The following hypotheses are to be tested: 1) The LSC treatment arm will show lower unprotected sex risk, meaning lower frequency of unprotected sex (vaginal + anal) with high risk partners at 6 months post intervention compared to an attention control arm 2) The LSC treatment arm will show higher participation in HIV testing at 6 months post intervention compared to the control. If effective, this video intervention could be rapidly implemented and brought to scale at low cost via the Internet, widely reaching young urban women with the goal of reducing HIV risk behavior and increasing HIV testing.

To assess the effectiveness of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing and treatment during pregnancy to reduce adverse pregnancy and birth outcomes compared to the standard of care (treatment based on symptoms and signs).

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 objective of the study is to determine the efficacy and safety of 0.5% and 2% PRO 2000/5 gels compared to placebo in preventing vaginally acquired HIV infection.

Urogenital Chlamydia trachomatis infection is the most common bacterial sexually transmitted infection in Norway. Urogential C.trachomatis infection can easily be treated with antibiotics. However, left untreated it is a major cause of pelvic inflammatory disease (PID) that can lead to complications such as infertility, ectopic pregnancy and chronic pelvic pain in women. Most infections are asymptomatic and many do not seek the doctor for testing. Therefore cases remain undetected and untreated.We want to determine the efficacy and feasibility of screening for urogenital C. trachomatis infection with home sampling (intervention) compared to the current strategy of conventional sampling at the doctor's office (control) in identifying men and women aged 18-25 years with urogenital C.trachomatis infection (Part A). We also want to identify factors influencing the acceptability of home sampling for C.trachomatis infections (Part B)and determine factors associated with C.trachomatis infections (Part C).

This is a multi-center study with a minimum of three sites in the United States. The study will enroll approximately 1750 female subjects 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.

As part of UCLA Health's commitment to developing a premier integrated health system built on a foundation of physician-led, team-based primary care, the Department of Medicine (DOM) recently implemented a new performance based incentive plan called the Primary Care Clinical Excellence (PCCE) Incentive Plan. This incentive plan was developed to motivate providers to improve health maintenance screening rates. The UCLA Health DOM Quality team is leading the implementation and evaluation of this new incentive plan across our primary care network. In addition, the DOM Quality team has partnered with the UCLA Anderson School of Management to study the most efficacious ways to frame and communicate performance based incentives. Understanding the factors that motivate physicians to deliver the highest quality primary care will provide pivotal insights into the successful implementation of performance based programs nationwide. The investigators believe that physicians who receive communication built on behavioral principles will demonstrate more motivation towards and success at meeting national primary care screening guidelines.

Though partner notification is mandatory to perform of Chlamydia trachomatis infected individuals in Sweden, there was a 10-15% annually increase of reported cases between 1997 and 2007 indicating that partner notification may not be effective in preventing transmission. The investigators wanted to determine whether there was any difference in time between home-sampling and clinical testing as a tool of partner notification measured from eliciting of partners to date of testing.

Consistent and correct use of an effective contraceptive method is a primary determinant in preventing pregnancy. Unfortunately, only a minority of healthcare providers adequately address women's contraceptive needs. We have developed a standardized behavioral-based contraceptive counseling model that can be used by providers and other clinic staff to address this limitation. The model, ESP, is an adaptation of motivational interviewing and involves: Exploring discrepancies between pregnancy intention and contraceptive use and between risk of STDs and condom use; Sharing information; and Promoting behaviors to reduce risk. Study question: Does ESP counseling lead to an increase in consistency and effectiveness of contraceptive use among women at risk of unintended pregnancy? Methods: Randomized controlled trial of 747 women, ages 16-44, at self-identified risk of unintended pregnancy enrolled from March 2003 to September 2004 at healthcare settings in North Carolina. Intervention participants received individualized ESP counseling from a health educator to address barriers to effective and consistent contraceptive use. Risk reduction steps were negotiated. Pregnancy, Chlamydia infection and contraceptive use were assessed at baseline and follow-up. "Highly effective" contraceptive use was defined as a combination of effectiveness and consistency. Women in the control arm received general preventive health counseling (e.g., smoking and exercise). Differences between the study arms at 12-months may illustrate the longer term influence of the intervention.
