Background

Sexually transmitted infection (STI) rates are increasing in the United States, with approximately half of new infections occurring among adolescents aged 15-24 years. Gay, bisexual, and transgender youth (GBTY), homeless youth, and youth with histories of drug use, mental health disorders, and incarceration are all at uniquely high risk for STIs. However, these adolescents often lack access to sexual health services.

Objective

This study aims to use point-of-care STI tests in community-based settings to screen for and treat STIs in adolescents.

Methods

We are recruiting 1500 HIV-uninfected youth and 220 HIV-infected youth from homeless shelters, GBTY organizations, and community health centers in Los Angeles, California and New Orleans, Louisiana. Study participants will receive STI screening every 4 months for 24 months. STI screening includes rapid HIV, syphilis, Chlamydia trachomatis, Neisseria gonorrhoeae, and Hepatitis C virus testing. Trained paraprofessionals will conduct all STI testing. When a participant screens positive for an STI, they are either linked to a partner medical clinic or provided with same-day antibiotic therapy and expedited partner therapy. We will monitor STI prevalence among study participants as well as point-of-care test performance, linkage to care, and treatment outcomes.

Results

The project was funded in 2016, and enrollment will be completed in 2019. Preliminary data analysis is currently underway.

Conclusions

As STI rates continue to rise, it is important to improve access to screening and treatment services, particularly for high-risk adolescents. In this study, we aim to evaluate the use of point-of-care STI diagnostic tests in community-based organizations. We hope to determine the prevalence of STIs among these adolescents and evaluate the acceptability and feasibility of community-based STI screening and treatment.

Background

Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) infections during pregnancy are linked with adverse birth outcomes. However, few countries have prenatal CT, NG, or TV screening programs. In this study, we aimed to evaluate the acceptability and feasibility of CT, NG, and TV screening and treatment among pregnant women across 6 low- to middle-income countries.

Methods

A total of 1817 pregnant women were screened for CT, NG, and TV in Botswana, the Democratic Republic of Congo, Haiti, South Africa, and Vietnam. An additional 640 pregnant women were screened for CT in Peru. Screening occurred between December 2012 and October 2017. Acceptability of screening was evaluated at each site as the proportion of eligible women who agreed to participate in screening. Feasibility of treatment was calculated as the proportion of women who tested positive that received treatment.

Results

Acceptability of screening and feasibility of treatment was high across all 6 sites. Acceptability of screening ranged from 85% to 99%, and feasibility of treatment ranged from 91% to 100%.

Discussion

The high acceptability and feasibility of screening and treatment of CT, NG, and TV among pregnant women supports further research to evaluate the cost-effectiveness of prenatal CT, NG, and TV screening programs.
