RA is what?
|
an autoimmune disease that eat's away at the bones and joints
|
|
Irreversible joint damage can occur with in how many years of the disease?
|
2
|
|
What are 3 main signs of RA
|
-Chronic
-Systemic -Inflammatory |
|
How is RA caused?
|
-antigen forms abnormal IgG
-antibodies form RF -IgG & RF deposit on synovial membrane and joint cartilage -inflammation occurs attracting Neutrophils causing damage and synovial lining thickens -Chronic inflammaton results |
|
Pannus is what?
|
(highly vascular granulation tissue)
-occurs at the junction of synovial tissue and articular cartilage - it will project into the joint cavity and cause necrosis |
|
The pannus occurs generaly where?
|
all around the joint cartilage
|
|
the inflammation leads to what?
|
-destruction of connective tissue and synovial membrane within the joints
-weakens the joints leading to dislocation and deformity |
|
So in a nut shell RA happens and does what?
|
-autoimmune in which the body attacks the joints
-swelling occurs -synovitis occurs -the synovial fluid thickens and forms pannus -the pannus then destroys cartliage |
|
(T/F)
RA is symmetrically in occurance |
True,
wrists, hands, elbows, shoulders, knees, ankles common |
|
RA criteria are
|
-am stiffness for an hour
-arthritis of 3 months -hand joint involvement -Rheumatoid nodules -Rheumatoid Factor (RF) positive -Radiographic changes |
|
RA S/S are
|
-fatigue & weakness
-inflammation -tenderness -pain longer than 30 min -joint deformity -decrease ROM -anoxrexia, Wt loss, anemia -high ESR, anti-CCP -X-rays showing joint destruction -WBC >2000 |
|
Joint symptoms
|
-Pain
-stiffness after inactivity -limited motion -inflammation -symmetrical -joint deformity |
|
RA can have what 3 types of extra articular manifistations?
|
-Rheumatoid nodules (firm non-tender nodules over joints)
-Sjogren syndrome (decreased lacrimal & salivary gland secretions) -Felty syndrome (inflammatory disease of the eyes, plenomegaly, lymphadenopathy, pulmonary disease and blood dyscrasias) |
|
Nodules can also spread where else?
|
to the lungs, heart, and eyes
|
|
What is commonly given to somebody with Sjogrens, or maybe Felty?
|
artifical tears
|
|
What can happen to these nodules?
|
They can open up and become a portal for infection
|
|
What are some "names" for the hands of RA Pt's?
|
-swan neck
-ulnar deviation -Boutonniere demority (the thumb curves outward) |
|
Rheumatoid factor (RF) is what?
|
-an antibody that activates the inflammatory processes within the body
-titers increase during active disease -can be misleading since it also rises with bacterial, viral and parasitic disease |
|
What is thought be replacing RF?
|
Anti-CCP (Cyclic citrullinated peptide antibody)
|
|
% of RA Pts with RF vs. Anti-CCP
|
RF 80%
Anti-CCP 98% |
|
Anti-CCP is useful how?
|
-Useful in evaluating early inflammatory arthritis
-if positive, can lead to more rapid initiation of more advanced RA Therapies |
|
TNF (tumor necrosis factor) does what during RA?
|
increases in their synovial fluid, blocking TNF decreases effects of RA
|
|
ESR
Erythrocyte Sedimentation Rate shows what? |
It measures the distance the RBC settle in 1 hr.
-ESR of 30 or less is normal -40-70 is moderate inflammation -70-140 is severe inflammation |
|
ESR in RA means what?
|
supports RA as a diagnosis and shows severity of inflammation
|
|
What is our Goal for RA?
|
-satisfactory pain relief
-minimal loss of functional ability -Pt participation in therapeutic regimen -maintenance of a postive attitude |
|
Drug therapy for RA consists of what drug groups?
|
-NSAIDS
-Corticosteroids -DMARDS -Biologics |
|
NSAIDS are what?
|
non-steroidal anti-inflammatory drugs
(they aren't selective) |
|
S/E from NSAIDS are what?
|
-GI upset
-Esophagitis -Gastritis -CNS problems (dizzyness) -Skin rash |
|
NSAIDS meds
|
-Ibuprofen
-Naproxen -Indomethacin |
|
What are the reasons for NSAIDS?
|
-decrease joint pain and swelling
|
|
What drug is commonly given with NSAIDS?
|
misoprostol (Cytotec) to cover GI problems
|
|
What is the selective NSAID?
|
Cox 2 inhibitor (Celebrex)
-blocks pain, edema, inflammation -shouldn't cause GI irritation |
|
What is going on with Cox 2 inhibitors?
|
Celebrex is one of the only ones not to be taken off the shelves due to increased CVA problems
|
|
DMARDS are what?
|
disease-modifying anti-rheumatic drugs
|
|
What general info is with DMARDS?
|
-slow acting
-maybe used alone or in combo with other drugs -can deminish progression of disease |
|
What are the 2 problems with DMARDS?
|
-Liver damage (CBC)
-Birth defects |
|
What are some DMARDS?
|
-Arava
-Plaquenil -Methotrexate |
|
Which DMARD is used first and also a melaria drug?
|
Plaquenil
(vision problems see dr. Q6 months, N/V) |
|
Which DMARD is drug of choice for mod-severe RA?
|
Mehotrexate
|
|
Biologics are considered what?
|
The Big guns in treating RA
|
|
They are often combined with what?
|
DMARDS to improve efficacy
|
|
What are some Biologics?
|
-Enbrel
-Humira -Remicade -Kineret -Orenica -Rituxan |
|
What can't be given to somebody taking Biologics?
|
live vaccine
|
|
Biologics do what?
|
-sup. inflammatory process
CAUSES -anemia -thrombocytopenia -neutropenia -can reactivate TB -lymphoma |
|
methotrexate and biologics does what?
|
-works better than using each alone
-using together increases the risk of infection and recur. of TB |
|
What two groups of drugs slow the progression of the disease?
|
-DMARDS
-Biologic |
|
one of our main goals is what?
|
preserve joint function
|
|
what can we do to preserve joint function?
|
-ROM exercise
-Alternate rest & activity -may splint joints during acute inflammation -apply heat or cold as prescribed -paraffin baths/massage -relaxation tech |
|
Why aren't we focused on preventing RA like we are in OA?
|
Because RA is autoimmune, we can only slow it down, not prevent it
|
|
What are some complications of RA?
|
-contractures
-cataracts -nod ulceration leading to open wounds -fatigue |

|
What could make RA worst?
|
-physical/emotional stress
-Risk Factors are exposure to infectious agents, fatigue, stress |
|
what should we teach our Pt with RA?

|
surgical fusion of a joint to attempt to relieve pain & stabilize the joint
