Brief summary

The purpose of this research study is to see if patients with juvenile idiopathic arthritis or seronegative arthritis (and related conditions) mount protective immune responses to the human papillomavirus (HPV) vaccine called Gardasil. The researchers also want to monitor for any increase in disease activity following receipt of the vaccine.

Detailed description

Each individual subject's participation is scheduled to last approximately two years. Patients will be given Gardasil injections at months 0, 2, and 6. Patients will have geometric mean titers (GMT) measured at 7, 12, and 24 months. Questionnaires about health and function will also be completed at each visit.

Interventions

OTHERBlood Draws for Serum Titers

All study subjects are receiving the Gardasil vaccine as part of their clinical care. The Gardasil vaccine is not given because of study participation. The study observes outcomes related to this clinical care. Study intervention consists of some blood samples taken to measure antibody and RNA titers. Other study specific procedures performed include Questionnaires and observational data.

Inclusion criteria

* Female patients, age 9-26 years, with polyarticular JIA, pauciarticular JIA, and sero-negative arthritis.

Exclusion criteria

* Pregnancy * Known allergy/sensitivity or any hypersensitivity to yeast or components of study drug or their formulation * Systemic onset JIA with active systemic symptoms (systemic onset JIA with polyarticular features but no fever or rash may be included). * Prior vaccination against HPV * Known HPV infection * Current or history of cervical cancer or cervical intraepithelial neoplasia (CIN). Males are excluded from this study because Gardasil® is currently approved only for females.

Recruitment details

Patients were recruited from pediatric rheumatology clinics at UHCleveland Medical Center, Cleveland Clinic, the MetroHealth System, and the University of Chicago. Recruitment began in October of 2007 (IRB approval 10/22/2007) and finished in October of 2014.

Pre-assignment details

This is open label vaccine on top of current therapy.
