What are some diagnostic studies for RA?
Give this one a try later!
Lab studies: RA factor (RF), ESR, C-reactive protein (CRP), antinuclear
antibody (ANA), anti-citrullinated protein antibody (ACPA)
Synovial fluid analysis
X-rays of involved joints
Bone scane
What are some diagnostic studies for OA?
Give this one a try later!
Bone scan, CT, MRI = detects early joint changes
Synovial fluid analysis = differentiates between OA and other inflammatory
arthritis
-OA = looks yellow colored
, -RA = looks strawberry colored
No specific lab biomarkers for OA
Incidence of RA
Give this one a try later!
Affects of ethnicities
Incidence increases with age, peaks 30-50
1.3 mil americans
Women > men
What is the etiology and patho of OA?
Give this one a try later!
Not a normal part of aging
It is an erosion of the articular surfaces
Cartilage destruction begins between 20-30 years, but symptoms do not
manifest until 50-60 years
50% of people >65 have at least one joint affected
Women > men
Inflammation is not characteristic
Secondary synovitis may occur - contributes to early pain and stiffness
Pain in later disease from bone to bone contact
Nursing implementation: health promotion
