What is the peak onset for R.A.
|
age 25-45
|
|
Who suffers more from R.A. M or F
|
F>M 3:1
|
|
When is a women likely to experience relief from R.A.
|
improves during pregnancy and flares 4-6 weeks post partum
|
|
What effect does R.A. have on mortality rates in general
|
Pts with rheumatoid arthritis have higher mortality than Gen'l population
|
|
What are the classification criteria for R.A.
|
at least 4 of the following for >6wks; morning stiffness lasting >1hour, swelling in 3 or more joint areas, swelling in hand joints, symmetric joint swelling, rheumatoid nodules, rheumatoid factor, erosions or osteopenia on hand x-ray
|
|
What is the pathophysiology of R.A. I.e. what is the underlying cause
|
swollen inflamed synovial membrane
|
|
What is the pathognomonic cellular finding for R.A.
|
Pannus (hypertrophic Synovium)
|
|
What is the problem with pannus (hypertrophic Synovium)
|
normally synovium doesn't cover cartilage in R.A. you get invasion of synovium into the cartilage, tendons and ligaments
|
|
What joints are classically involved in R.A.
|
MCPs, PIPs (80%), Wrist 80%, Knee 80%, Ankle Subtalar 80%, MTPs 90%, shoulder 60%, C-Spine 40%, TMJ 30%
|
|
What joints are noticeably absent in involvement in R.A.
|
Spine except C-Spine
|
|
Which hand joint is spared in R.A.
|
DIP joints are typically spared
|
|
If you find ulnar deviations, interossei atrophy and subluxations what stage of R.A. is your patient in
|
advanced stages
|
|
Outside of the joint you can get signs and symptoms of R.A. name 5
|
Rheumatoid Nodules, Sjogren's syndrome, Felty's syndrome, vasculitis, Rheumatoid lung, cardiac disease, neuromyopathy, inflammatory eye disease, osteoporosis, lymphadenopathy, hyperviscosity, cryoglobulinemia, dermatologic, amyloidosis
|
|
If pt has rheumatoid nodules what other positive finding will you always find
|
Always Rheumatoid Factor +
|
|
Your pt presents with R.A. and sever neck pain radiating to occiput, have diminished motor power in arms/legs, dysesthesias of the fingers/feet, marble sensation in the limbs/trunk, jumping legs, disturbed bladder function what could be causing this
|
Myelopathic leading to spinal cord damage from degeneration of the C-SPINE
|
|
What is Sjogren's syndrome
|
autoimmune exocrinopathy, sicca symptoms (dry eyes, mouth, vagina, tracheo-bronchial dryness) associated with SS-A (RO) and SS-B (LA) antibodies and is tx symptomatically
|
|
What is the schirmer's test for
|
tests for tear production can help identify Sjogren's or other malfunction in tear formation
|
|
What are nail fold infarcts
|
small vessel vasculitis that can indicated R.A.
|
|
What lab findings are you likely to find in R.A.
|
+ rheumatoid factor, Anti CCP antibody, Elevated ESR or CRP, Anemia, Thrombocytosis, ANA +, Hyperglobulinemia, Leukopenia/granulocytopenia, glucose in body fluids very low
|
|
Besides R.A. what other disease may show rheumatoid positive finding
|
Syphilis, sarcoidosis, SLE, SBE, T.B., Leprosy, Parasitic infections, Viral Disease, advanced age, autoimmune disease
|
|
What are the two areas of R.A. that we can effectively tx
|
alleviate pain, slow rate of joint damage
|
|
What is one of the limitations of DMARDs for tx of R.A.
|
high discontinuation rate (toxicity/efficacy) needs continued monitoring, has delayed onset of action
|
|
What type of drug are the following- Hydroxychloroquine (Plaquenil), Sulfasalazine (Azulfidine), Gold Compounds, Azathioprine (Imuran), D-Penicillamine (D-pen & Cuprimine), Cyclosporine (Sandimmune), Methotrexate (Rheumatrex, Trexall), Leflunomide (Arava)
|
DMARDs
|
|
What are the pros of using methotrexate
|
long term clinical experience, favorable rate of continuing therapy, proven efficacy in moderate-severe RA
|
|
What are the Cons of using methotrexate
|
Lab Monitoring 4-8wks, Toxicities; hepatic, myelosuppression, pulmonary
|
|
What are the pros of using Leflunomide
|
Well absorbed PO, early onset of action, stabilized benefit for long-term use, selectively target autoimmune lymphocytes to reduces AEs
|
|
What are the cons of Using Leflunomide
|
Lack of Clinical Experience, Toxicities- hepatic, GI, Teratogenic
