How is RA diagnosed?
Sensitive- (+) Rheumatoid Factor (good initial test)

- Screen for HBV and HCV for all DMARDs

- **Other options (non-biologics):
- Leflunomide
- Hydroxychloroquine- retinal toxicity ADR :(
- Sulfasalazine
How is the pain of RA addressed (what meds)?
- NSAIDs 1st line
- Corticosteroids 2nd line
_____ is associated with OSTEOPHYTE formation and narrowed joint space. Evening joint stiffness decreases w/ rest.
PE: hard, bony joints. Heberden’s and Bouchard’s nodes.
Osteoarthritis
*Treatment- Tylenol in elderly to avoid bleed risk although NSAIDs more effective in other populations
_____ is an autoimmune response to an infxn in another part of the body. it is associated w/:

- Radiographs- Mouse/Rat bite, punched out erosions w/ overhanging margins
Acute treatment of gout involves…
- NSAIDs- Indomethacin, Naprosyn. AVOID ASA
2. Colchicine is 2nd line
Chronic treatment of gout involves…
