Further study details as provided by University of Nebraska:

Primary Outcome Measures:
  • Bone mineral density [ Time Frame: baseline and at 5 years disease ]

Biospecimen Retention:   Samples With DNA
Baseline sera and DNA collected

Enrollment: 1745
Study Start Date: July 2004
Study Completion Date: January 2013
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
CLEAR enrollees include African American patients with early rheumatoid arthritis, as defined using ACR criteria
VARA enrollees will include male veterans with established RA diagnosed using ACR criteria

Detailed Description:

The overall hypothesis of this study is that osteopenia and/or osteoporosis are common among African Americans and men with rheumatoid arthritis and there are identifiable genetic and environmental factors contributing to the pathogenesis of bone loss in these groups.

The Specific Aims of the study are to:

  1. Determine baseline hip and lumbar spine bone density (BMD) values and osteopenia/osteoporosis prevalence among African American men and women with early RA and among male veterans with established RA.
  2. Identify environmental factors and candidate alleles, which confer increased risk of reduced baseline BMD loss over time among African American men and women with early RA and among male veterans with established RA.

Ages Eligible for Study:   19 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
CLEAR enroll African American RA patients from 4 core academic centers in the Southeast U.S. VARA enroll RA patientss from participating VA medical centers.

Inclusion Criteria:

  • Clinical diagnosis of rheumatoid arthritis per ACR guidelines

Exclusion Criteria:

  • Patients with diagnosis > 2yrs (CLEAR study)
