Active clinical trials for "Chlamydia Infections"

This study aims to evaluate different screening strategies to decrease the burden of Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and Trichomonas vaginalis (TV) among pregnant women, and reduce adverse birth outcomes. In turn it aims to evaluate the cost per pregnant woman screened and treated, cost of adverse birth outcomes, and cost-effectiveness per sexually transmitted infection (STI) and disability-adjusted life-year (DALY) averted. Furthermore, this study will incorporate a vaginal microbiome sub-study aimed to investigate the relationship between the vaginal microbiome and persistent Chlamydial infections in pregnant women. Aim 1 and 2: The intervention includes diagnostic testing at a woman's first antenatal care visit using the Xpert® platform with same-day treatment for Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis infection with either a test-of-cure three weeks post-treatment (arm 1) or a repeat test at 30-34 weeks gestation (arm 2) compared to the standard of care, i.e. syndromic management (arm 3). Aim 3: Case-control study to investigate role vaginal microbiome in STI treatment outcomes

This study aims to identify the relationship between genital C. trachomatis and adverse pregnancy outcomes, and investigate whether screening and treatment of genital C. trachomatis in pregnant women can reduce adverse pregnancy outcomes. Approximately 200 pregnant women from Nanhai Hospital of Southern Medical University in Guangzhou, China will be enrolled and randomized to the intervention or control group.

This is a Phase 4 blinded, randomized, active-controlled, non-inferiority trial. Persons of any gender identity will be eligible. Final evaluable population will include a minimum 596 individuals: 298 persons assigned female sex at birth (AFAB) with confirmed urogenital chlamydia (CT) and 298 persons assigned male at birth (AMAB) with confirmed rectal chlamydia (CT). Approximately 664 participants will be enrolled to achieve a minimum 596 participants who contribute primary outcome data. Randomization will be stratified by study site and sex at birth: 332 persons assigned female sex at birth (AFAB) and 332 persons assigned male sex at birth (AMAB). Participants will be randomized 1:1 to a 3-day regimen of doxycycline or a 7-day regimen of doxycycline. The study blind will be maintained by providing 7 days of identical pre-filled blister packs, one with 3 days of active treatment and 4 days of placebo, and the other with 7 days of active treatment. Participants will be asked to return 28 days after randomization (at day 29), at which time they will be re-tested for chlamydia (CT) using a laboratory-based chlamydia (CT) nucleic acid amplification test (NAAT).

This study will evaluate whether EVO100 vaginal gel prevents the sexual transmission of CT and GC infection

Project FEDE-ITS will improve the STI knowledge and its treatment, of adolescents in the 1st and 2nd year of compulsory secondary education in the intervention group compared to compared to the control group, and will modify the sexual risk practices and the perception of risky practices of alcohol and other drug use during sex of participants in the intervention group compared to the control group.

The mainstay of treating both symptomatic and asymptomatic genital Chlamydia trachomatis infection has been macrolide antibiotics in the form of azithromycin, and alternatively tetracycline antibiotics in the form of doxycycline. Studies from the late nineties found a single dose of 1 g azithromycin to be equally effective as a 7 day course of 200 mg doxycycline a day. However, recent studies have reported increasing treatment failure that may indicate that resistance to macrolide antibiotics among Chlamydia trachomatis is evolving. Research regarding other bacterial species indicates a high frequency of mutation based resistance in conjunction with azithromycin use, i.e. when treating Mycoplasma genitalium infections. There has only been case reports of tetracycline resistance among human Chlamydia isolates, but a recent study suggest that there might be decreasing effectiveness also for doxycycline. Veterinaries has for several years observed increasing prevalence of tetracycline resistance among Chlamydia suis. Within the Chlamydia population there is promiscuous horizontal gene transfer. If the current trend of declining cure rates continues, the investigators might face a situation where there are no documented and effective treatments for Chlamydia trachomatis infections. This underline an urgent need to expand the number of documented treatment options and mecillinam seems to be one of the options that warrant further investigation. The objectives of this study is to prove the concept of treating genital Chlamydia trachomatis with mecillinam (Pivmecillinamhydrochlorid).

1. This study is a non-randomized observational cohort trial using before and after comparison to evaluate intervention 2. It would mimic the conditions that would occur outside a clinical trial. 2. After consent and enrolment, all procedures will be guided by the Australian STI Management Guidelines. 3. All enrolling participants will be offered daily doxycycline 100mg 4. All participants will be invited to complete a survey in every 3 months time for 12 months dated from participation. 5. All follow-up information will be collected through electronic data capture to allow accurate and timely analyses. 6. Data collection will be from (i) medical records (ii) online self-completed questionnaire

The frequency of Chlamydia trachomatis and Neisseria gonorrhoeae coinfection can vary depending on their individual incidence and prevalence rates.Single-agent therapy with ceftriaxone is the preferred regimen for treatment of gonococcal infections. If an injectable cephalosporin is not available, cefixime is the only oral cephalosporin that can be used for gonococcal therapy. Doxycycline was recommended for presumptive treatment of chlamydia in nonpregnant individuals with gonococcal infection. The study is conducted to evaluate the effectiveness of two regimens in combination with doxycycline with cefixime or ceftriaxone.

Sexually active adolescents between the ages of 10 and 19 are at extremely high risk for sexually transmitted diseases (STD), including HIV, and teen pregnancy.The overall goal of this research program is to develop, implement and evaluate integrated multi-level interventions to prevent STD, including HIV, and pregnancy among adolescents. The study includes 12 high schools and 19 of their feeder middle schools in the Los Angeles Unified School District and the surrounding communities. Interventions will be implemented among parents, health care providers, and in schools in an integrated fashion with the goal of improving social context factors related to health outcomes among adolescents. The evaluation phase will include in-school surveys with adolescents at all middle schools

This is a Phase 3, multi-center, randomized, placebo-controlled trial to determine the effectiveness and safety of the 6% cellulose sulfate (CS) vaginal gel for the prevention of HIV infection.
