RA and Fibromyalgia Flashcards
Rhumatoid Arthritis definition
Chronic, systemic, inflammatory autoimmune disease
Symmetric , erosive synovitis of Peripheral joints
Can be associated with
Extra-articular manifestations
What is the difference between RA and OA?
RA systemic , bilateral joints, autoimmune , affects the synovial fluid, extra-articular , reversible i caught early
OA: may just be an issue on one side, wear and tear
RA is characterized by _____ and _____
Synovitis (inflammation of the synovium) and joint destruction
70 percent of patients develop joint damage /erosion within ___ years of the onset
2 years
33% of patients are work disabled at __ years
5
WHO functional classification RA
1-4
Class 1: symptom free when PA or rest
Class 2: no symptoms at rest, but normal activities cause discomfort and SOB
Class 3: no symptoms at rest but normal activities are greatly limited
Class 4: symptoms at rest
True or false , RA is present before the first symptoms
True
Etiology / risk factors for RA
Antigens
Genetic susceptibility
Pathophysiology of RA
Immune hyper activation cycle : no off signal
- Antigen (toxic /foreign substance)
- Synovial inflammation
- Cytokines (immune response) release by macrophages
- Cytokines induce fibroblasts - result inn bone destruction
Screening tool for inflammatory arthritis (RA)
- significant discomfort in squeezing MCP, MTP
- prescience of 3 or more swollen joints
- more than 1 hour of morning stiffness
Extra-articular manifestations
– Scleritis (red eyes) referral ASAP
– Rheumatoid nodules (bumps)
– Vasculitis (necrosis )
– Interstitial lung disease
– Pericardial disease
Poor prognostic factors of RA
earlier onset
female sex
polyarticular synovitis (>13 joints)
lab tests:
high titer Rheumatoid factor / anti CCP
elevated ESR rate or CRP level
HLA-DR4
erosion of cartilage loss on x ray in less than a year
poor functional status
extra-articular manidestations
HAQ
Health assessment questionnaire assesses ADL’s / fine motor and gross motor
RA joint manifestations
C spine: atlantoaxial subluxation due to laxity /rupture of transverse lig.
shoulder: H/AC joint , RTC and or bicep tendonitis/rupture,
elbow: nerve entrapment, olecranon bursitis
hip:bursitis, avascular necrosis
knee: quad atrophy, bakers cyst
Hand and wrist joint manifistatitons
MCP,PIP wrist synovitis
ulnar drift
swan neck, butonniere deformity
tenodynovitis
