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.
The HIV epidemic in Peru remains concentrated in the subpopulation of men who have sex with men (MSM), where the prevalence of disease has been estimated between 10-22% in recent epidemiologic surveys. Partner-based methods to limit the spread of HIV and STI co-infection, including partner notification and partner treatment, provide an important new strategy for HIV control in the region. Expedited Partner Therapy (EPT) has been shown to reduce rates of persistent or recurrent gonorrhea and chlamydia infection in heterosexual patients, but has not been fully evaluated for use among men who have sex with men (MSM). CDC guidelines support the use of EPT for partner management with heterosexual patients, but note the absence of evidence necessary to make an equivalent recommendation for the use of EPT with MSM. Randomized clinical trials to assess the impact of EPT on partner notification, treatment, and STI re-infection among MSM are critical to the development of evidence-based partner management guidelines. As a theoretical model, EPT integrates behavioral, social, and biomedical approaches to HIV/STI control in a comprehensive prevention intervention. Our proposed exploration of the social and behavioral dimensions of partner notification and treatment will provide a methodological structure for understanding the influence of EPT on behavioral decision-making processes, interpersonal factors that influence partner notification, and network patterns of STI transmission within MSM populations in Peru. The proposed study includes a screening protocol to identify eligible MSM subjects for participation in our planned study of the effect of EPT on partner notification, treatment, and linkage to HIV prevention and care services. Potential participants will complete a behavioral survey and undergo physical examination and testing for HIV, syphilis, gonorrhea, and chlamydia. Participants diagnosed with Gonorrhea and/or Chlamydia (at any anatomic site) will be eligible for enrollment in our Partner Management study of EPT and the HIV prevention cascade among MSM in Peru. Participants in the Partner Management study will be randomly assigned to receive either standard of care partner notification counseling or standard counseling along with a maximum of five antibiotic treatment packets to deliver to their recent sexual partners. Participants will be asked to return to the site after 21 days to report on their actual partner notification behavior, with differences in notification evaluated between the two groups. Participants will then work with a study counselor to identify their recent partners and, if the participant agrees, to provide contact information so that the study team can contact these partners. Study staff will either confirm that the partner has already been notified, or provide notification of their likely STI exposure. After informing partners of their STI exposure, staff will ask partners to provide verbal consent to a single question evaluation (whether or not the partner had previously been informed of their exposure) to verify participant-reported behavior. Partners will also be asked to visit the study site to complete a brief survey of their sexual practices and treatment-seeking behavior, as well as to undergo testing for HIV and STIs. All of the above data will be used to construct models of the spread of HIV and STIs in local MSM networks, and the potential effect of EPT on controlling the spread of STIs in this population.
The purpose of this study is to understand if taking an antibiotic called doxycycline by mouth as soon as possible after sexual contact without a condom can reduce the risk of sexually transmitted infections (STIs), including gonorrhea, chlamydia and syphilis. The study will also look at the safety of doxycycline PEP and the impact that PEP may have on the bacteria that cause STIs as well as on bacteria that normally live on the body. While doxycycline is approved by the Food and Drug Administration (FDA), taking doxycycline immediately after sexual contact to prevent infection is investigational and is not approved by the FDA for this use. Participants will take part in the study for 1 year.
Sexually transmitted infections (STIs) are highly prevalent among adolescents. Despite established principles for STI control, clinical practices related to screening and diagnosis, treatment, and prevention of STIs among adolescents are suboptimal. There is an urgent need to expand our screening programs to nontraditional healthcare settings such as emergency departments (ED) to reach those adolescents who would otherwise not receive preventive healthcare, and to determine the most efficient and cost-effective method for providing this screening. The goal of this study is to leverage our recent insights obtained from single center ED-based adolescent gonorrhea and chlamydia screening research and apply them across a national pediatric ED research network to determine the most clinically effective and cost-effective screening approach for adolescents when implemented into a real-world clinical setting through a pragmatic trial. This will be accomplished through a network of children's hospital EDs with a track record of robust research collaboration (Pediatric Emergency Care Applied Research Network or PECARN). This intervention will rely on an innovative approach that electronically integrates patient-reported data to guide clinical decision support. The investigators will apply human factors modeling methods to perform ED workflow evaluations at each participating pediatric ED to determine the most efficient way to integrate the screening process into everyday clinical care. Following these analyses, the investigators will conduct a comparative effectiveness pragmatic trial of targeted STI screening (screening only those disclosing high risk sexual behavior) versus universally-offered STI screening (offered to all, regardless of risk) through electronic integration of patient reported data for provision of clinical decision support. The investigators will then develop decision analytic models to evaluate the cost-effectiveness of targeted screening compared to universally offered screening.
