|Official Title:||Comparison of the Tuberculin Skin Test (TST) and QuantiFERON ®-TB Gold Test (QFT-G) In Patients With Rheumatoid Arthritis Being Considered for Anti-TNF-Alpha Therapy|
|Study Start Date :||May 2009|
|Estimated Primary Completion Date :||May 2011|
|Estimated Study Completion Date :||June 2011|
The study group will consist of RA patients of the Walter Reed Army Medical Center (WRAMC) rheumatology clinic being considered for treatment with anti-TNF alpha therapy. We will enter patients into the study over a projected course of 12-24 months or until we reach the statistical requirement of 60 subjects.
The control group will consist of healthy subjects without known immune-dysregulation or history of treatment with biologic agents who present to the WRAMC Allergy- Immunology clinic for routine screening TST as a part of current WRAMC policy.
- Primary endpoints are the results of the QFT-G test (defined as positive, negative or indeterminate) and the results of the TST (defined as positive or negative). [ Time Frame: Patients will be enrolled over a 2 year time frame ]
- Secondary endpoints include the percentage and numbers of CD45RO (memory T cells), the response PHA intradermal antigen placement, numbers of hypoergic TSTs, and the results of cell mediated immunity (CMI) assays. [ Time Frame: Patients will be enrolled over a 2 year time period ]
