Immunopathogenesis of Chlamydia

Arkansas Children's Hospital Research Institute29 enrolled

Overview

Sexually transmitted Chlamydia trachomatis infections are a widespread public health concern due to their prevalence and potentially devastating reproductive consequences, including pelvic inflammatory disease, infertility, and ectopic pregnancy. The goal of this study is to evaluate the risk factors for adverse outcomes following genital tract infection with Chlamydia trachomatis and to evaluate whether or not the presence of C. trachomatis in the rectum act as a reservoir for infection. Our target population will be adolescent females age 11-21 evaluated at the ACH Adolescent Center who are undergoing pelvic examinations or urine screening for sexually transmitted infections (STIs). Laboratory specimens obtained will include cervical and rectal swabs, urine and blood specimens, as well as, chart review and comprehensive subject interviews in the initial data collection with follow-up evaluations at 3, 6, 12, 24 and 36 months for qualifying subjects
