Filter by:Screening for STIs in MSM is based on multisite samples: urine, anal and oral for PCR targeting C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis, whereas only vaginal self-sampling is recommended in women. Recent publications and observations suggest that a substantial number of STIs are under diagnosed with the current recommendations. The main objective of the study is to assess the number and percentage of additional C. trachomatis and N. gonorrhoeae infections diagnosed by a multiple sampling strategy in women, particularly when the vaginal sampling is negative The secondary objective will assess the acceptability of anal and oropharyngeal self-sampling relative to vaginal self-sampling in women.
Objectives: Efficacy of a meningococcal vaccine against Neisseria gonorrhoea (NG) infection among men who have sex with men (MSM). Design: Parallel randomised double-blind placebo-controlled trial. Setting: A teaching hospital in Hong Kong. Participants: 150 adult MSM at risk of gonorrhoea infection (condomless sex with more than one man within the last six months, history of sexually transmitted infection [STI] diagnosis, inclination to have condomless sex, and other PrEP-eligible criteria) would be recruited into the trial, with half allocated to intervention and control group each. Intervention: Intervention and control group would receive, one month apart, two doses of meningococcal vaccine and normal saline, respectively. Main outcome measures: Safety and efficacy of vaccine against gonorrhoea (time to first gonorrhoea infection and incidence), and behavioural change after vaccination. Expected results: NG incidences in two groups would be compared. Efficacy of vaccine against gonorrhoea would be determined after controlling confounding variables. Characteristics of participants with incident NG would be distinguished from those without incident infections. Change of frequency of sexual activities and networking would be noted. Implications: Strategies on STI screening and vaccination could be informed. Reduced STI burden post-vaccination could be measured with surveillance system.
This couples-based, digital health intervention project is serostatus neutral and seeks to determine efficacy for: a) use and adherence to evidence-based HIV/STI prevention-care strategies; b) creation and adherence to a tailored prevention-care plan; c) creation and adherence to a tailored sexual agreement; and d) improvements in other relationship dynamics among male couples who are in a relationship (defined as greater than 3 months or more).
A prospective interventional study to evaluate a strategy of point-of-care testing for sexually transmitted infections including chlamydia, gonorrhoea, trichomoniasis, syphilis, and Hepatitis B with comprehensive case management including partner notification in antenatal settings in Harare province, Zimbabwe.
Programs which go beyond individual-level behavior change to reduce HIV and STI infections among adolescent girls and young women in sub-Saharan Africa are essential to meet global HIV targets. Informed, Motivated, Aware and Responsible Adolescents and Adults- South Africa (IMARA-SA) is an evidence-based HIV-prevention intervention for adolescent girls and young women (AGYW) and their female caregivers, which has been adapted for a South African audience. This pilot study will assess feasibility in preparation for a randomized controlled trial (RCT). Additionally, the pilot will examine the preliminary effectiveness of IMARA-SA in reducing sexually transmitted infections (STI) and increasing uptake of HIV testing and counseling (HTC) and pre-exposure prophylaxis (PrEP) at follow-up among AGYW. About 60 AGYW-FC dyads will be enrolled and randomized to IMARA-SA or a health-promotion control arm. Following randomization, the dyads will participate in an ~2-day group workshop (~10 hours), which includes joint and separate mother and daughter activities. AGYW and FC will complete baseline assessments and follow-up assessments approximately 6 months later. Assessments will include surveys, STIs testing (for chlamydia and gonorrhea), and uptake of HTC and a 1-month PrEP prescription. Additionally, the intervention's implementation (e.g., acceptability) will be explored.
A longitudinal study to investigate the prevalence of sexually transmitted infections among young women and determine the role of the female genital tract microbiome in fertility
Multicenter cohort study of individuals reporting behavioral risks of HIV acquisition, recruited among those presenting for testing for HIV and other sexually transmitted infections. Overarching goal: to study factors associated with uptake of HIV prevention and (re)testing services in medium-sized cities in Thailand. Primary objective: To estimate the incidence of HIV and other sexually transmitted infections (syphilis, chronic hepatitis B and C) among individuals presenting for retesting. Secondary objectives: - To evaluate the uptake of pre-exposure prophylaxis - To assess retention in the study - To evaluate client HIV knowledge - To describe HIV prevalence and characteristics of individuals newly diagnosed with HIV - To describe characteristics of individuals at risk of HIV infection - To assess the quality of the testing and referral services.
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
The goal of this study is to assess the impact of an intervention, known as SNAPS, to expand Preexposure Prophylaxis (PrEP) prescriptions at Health + Hospitals (H+H)/Bellevue. In addition, evaluating whether this intervention, ie SNAPS, helps patients get on PrEP and stay on PrEP to prevent STIs like HIV. PrEP is a medication that needs to be taken on a regular basis in order to be effective to prevent HIV transmission.
The study is a pragmatic, randomized controlled trial design to evaluate an online video series developed by a community-based organization in Singapore for gay, bisexual and queer men. A total of 300 HIV-negative, gay, bisexual and queer men in Singapore aged 18 to 29 years old will be recruited with the assistance of the partner community-based organization (CBO), Action for AIDS Singapore. Recruitment will utilize both online and offline channels, and with the help of other CBOs in Singapore. Participants should also not have watched the video prior to their participation in this study, which will be ascertained through a questionnaire. Participants will subsequently be randomized into the intervention arm (n=150) and the control arm (n=150). The treatment group (n=150) will be assigned the intervention along with sexual health information via a pamphlet, while the control group (n=150) will be assigned only the sexual health information via a pamphlet. This will be conducted through block randomization.
