Filter by: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.
This is a double-blind randomized controlled trial to test whether the group B meningitis vaccine 4 component Neisseria meningitidis serogroup B vaccine (BEXSEROTM) (4C-MenB), trade name Bexsero™), currently approved for use by the United States Food and Drug Administration (FDA) and recommended by the Centers for Disease Control and Prevention (CDC) for protection from Neisseria meningitidis infections, also protects from Neisseria gonorrhoeae infection using controlled human experimental infection to test protection. The information the investigator learn by doing this study may also help to develop a vaccine that protects individuals from having gonorrhea infection. The study population will consist of male participants > 18 and < 36 years old, living in central North Carolina, in general good health without a history of 4C-MenB vaccination. Approximately 120-140 participants will be enrolled. Participants will receive 2 doses of vaccine (2 doses of 4C-MenB or 2 comparator vaccines- seasonal influenza and tetanus/diptheria booster) as intramuscular injections, and then one intraurethral challenge with Neisseria gonorrhoeae. Following the challenge, participants will cross-over and receive two doses of vaccines not received prior to challenge (2 doses of 4CMenB or the 2 comparator vaccines- seasonal influenza and tetanus/diptheria booster) All participants receive all vaccinations by the end of the study and all vaccines used in this study are licensed and FDA-approved.
This study aims to test the effectiveness of using of SpeeDx Resistance Plus assay to guide treatment of Neisseria gonorrhoeae (Ng) in a sexual health clinic setting.
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.
This clinical trial aims to investigate the effects of a decline in methamphetamine use on rectal inflammatory cytokine levels, substance use contexts, and HIV/STI risk behavior. This clinical trial also seeks to evaluate joint effects of methamphetamine use and rectal gonorrhea/chlamydia infection on rectal inflammatory cytokine levels. The proposed trial will consist of 40 MSM, half with rectal gonorrhea/chlamydia infection at enrollment (n=20), with methamphetamine use disorder that will receive contingency management for methamphetamine reduction. Following baseline measurement, participants will be observed over the course of 8 weeks, where participants will complete behavioral surveys, provide urine for drug testing, and rectal samples for measurement of rectal inflammatory cytokine levels.
In this Randomized Controlled Trial, the investigators will recruit 42 men attending the STI and HIV clinic at the Institute of Tropical Medicine, with a diagnosis of N. gonorrhoeae and randomize them 1:1 to receive either ceftriaxone or ceftriaxone/azithromycin. They will be followed-up for a test of cure visit at day 14 post-treatment where urine, oropharyngeal and anorectal samples will be taken to test for cure and monitor treatment effects on the microbiome and resistome. The primary outcome will be evaluating the difference in the abundance of resistance conferring genes in the rectal microbiome in the two arms, 14 days after the receipt of therapy.
This study aims to determine acceptability and preliminary efficacy of daily use of an antibacterial mouthwash as compared to a placebo mouthwash in reducing the incidence of pharyngeal gonorrhea among a cohort of HIV-positive and high risk HIV-negative men. Investigators plan to test the following hypotheses: 1. Participants will maintain a high level of adherence and satisfaction with daily mouthwash use. Furthermore, the investigators hypothesize that barriers to adherence will include structural factors such as unstable housing and individual level factors such as substance use. 2. Participants receiving the antibacterial mouthwash will have a lower incidence of pharyngeal gonorrhea as compared to participants receiving the placebo mouthwash. Furthermore, the investigators hypothesize that these reductions will remain even after adjusting for other factors such as HIV-status and substance use.
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).
Sexual health centers (CeGIDD, in France) manage the majority of STI in France, especially gonorrhea. Patients wanting STI screening can consult either they are symptomatic or not. If they are symptomatic, they can be treated immediately. If they are not symptomatic, they must come back seven days after in order to get their results and to be treated if necessary. Before any treatment for gonorrhea, subjects should be sampled for bacterial culture in order to perform AMR surveillance. After every treatment for gonorrhea, subjects should realized a test of cure (TOC) according to current recommandation. Response rate to ceftriaxone 1g IM for treating gonorrhea has never been evaluated in France while being used widely over the past months. Compliance to current recommandation at CeGIDD Montpellier has never been evaluated. This study will assess the response rate to ceftriaxone 1g IM as gonorrhea treatment by realizing a test of cure 14 days after each treatment.
This is a Phase 1, interventional, non-randomized, experimental infection model study in healthy adult males (N=up to 25) between the ages of 18-35 at study enrollment. The study is designed to test the requirements of predicted N. gonorrhoeae virulence determinants for gonococcal infection in the male urethra through infection with engineered mutants of N. gonorrhoeae. We predict that mutations abolishing expression of N. gonorrhoeae virulence determinants will eliminate or significantly reduce gonococcal infectivity or the ability to induce inflammation in an infected individual, thus identifying potential vaccine candidates. Study duration will be 1 year, and the duration for all participants will be about 3 weeks. The primary objective of the study is to compare the ability of different engineered mutants of Neisseria gonorrhoeae to cause a clinical infection (signs or symptoms of urethritis such as discomfort during urination, urethral discharge, etc.) in the male urethra.
