**if you see any of these look for the third**
How is the diagnosis of RA made?
- Clinical criteria should lead to lab testing,
- Nobody Should Have Rheumatoid Symptoms 3 times
- Noduels
- Symmetric
- Hands
- RF or CCP
- Stiffness
- 3 or more joints
- X-ray findings of erosions
- Nobody Should Have Rheumatoid Symptoms 3 times
- Serology
- Rheumatoid factor or Anti CCP can be used
What is the treatment algorhythm for RA?
NSAIDs (Sxs) + DMARDS (everyone) + Biologics (severe) —- Steroids (flares)
- DMARDs
- Methotrexate (1st line)
- Leflunomide (2nd line)
- Hydroxychloroquine (pregnancy)

- Check for occult malignancy and treat with high dose steroids
What is the underlying gene of the spondyloarthropathies?
B27, but this isnt the end all be all of diagnosis. Theyre seronegative: No RF, CCP, ANA reactive antibodies
