How Common are Sexually Transmitted Co-infections among Youth with HIV and AIDS?

Statement of Problem

Rates of new HIV infections are increasing among adolescents and young adults. Co-infections with other sexually transmitted infections (gonorrhea, chlamydia, syphilis, human papillomavirus, herpes simplex virus) cause health issues by themselves and can actually increase transmission of HIV. There are few studies that describe the prevalence and correlates of STI co-infections among HIV positive youth.

This project aims to understand how and why adolescents with HIV continue to acquire other sexually transmitted infections (STIs). The study includes HIV-positive youth ages 12-26 years at the Children’s Hospital of Philadelphia’s Adolescent Initiative Clinic and Family Care Center. The study follows the youth from the time of initial diagnosis and throughout the duration of their care by reviewing medical records during a 9-year period. We seek to understand the prevalence and patterns of gonorrhea, chlamydia and syphilis infection. We also examine how different risk and protective behaviors may be associated with the likelihood of STI co-infection among these youth.

These results will inform the development of treatment and prevention guidelines and interventions within the institution and will be shared at national meetings with the intent of developing broader guidelines for STI identification and treatment among adolescent healthcare providers nationally.
