Dr. Lea Widdice, working with researchers at Cincinnati Children’s and UCSF, studied HPV transmission in 25 young adult couples. She examined multiple sites for HPV presence, by HPV type, in a longitudinal study. Women with HPV persistence are much more likely to have the same type detected in their partners than women with transient HPV infections (p=0.04). The high rate of type-specific HPV concordance in the anogenital area between couples was striking, supporting the ease to which HPV is transmitted between couples. Although the palm and mouth were uncommon sources for infections, when discordance occurs, the discordant type can be found in non-genital areas of the partner negative for that HPV type in the anogenital area.
Dr. Tanya Mullins and colleagues have been evaluating adolescent preferences for different HIV testing methods. Three different HIV testing methods were offered to 200 study participants, who also completed a survey assessing HIV/Aids knowledge, beliefs about HIV testing, and HIV risk behaviors. Even when offered a choice of HIV testing methods, only half of adolescents agreed to HIV testing. Of those, 50% chose rapid oral fluid testing, 30% chose traditional venipuncture testing, and 19% chose rapid fingerstick whole blood testing. Agreement to test for HIV was associated with male gender, parental education, perceived likelihood of current HIV infection, and intention to obtain HIV testing if offered by a health care provider. Participants who chose a rapid test method were significantly more likely to receive their HIV test results. With the release of the 2006 Centers for Disease Control and Prevention (CDC) recommendation to test every person for HIV (regardless of risk), insight into adolescent HIV testing preferences and attitudes will allow providers to offer HIV tests that are most acceptable to teens, leading to increased uptake of HIV testing by adolescents and identification of previously undiagnosed HIV positive individuals.
Dr. Jill Huppert demonstrated that the rapid antigen test for Trichomonas could be delayed until after the wet mount, with no loss of sensitivity, and that this wet mount followed by a rapid antigen test for T. vaginalis was the best approach to detect infections. In another presentation, Dr. Huppert reported that women with a positive point of care test were more likely to realize that they had an STI, and to adopt safer behaviors such as abstinence, partner notification, and partner treatment. These results can be useful in evaluating how adolescents may respond to other point of care tests and even home-based testing. In a collaborative project with the Emergency Department, she noted that a recruitment bias occurs when parental permission is required to enroll minor women in STI research. This work will help inform IRBs to allow minor teens to consent for STI research without parental permission in order to avoid biased scientific results.
