1% population
2.5x more in women
ages 30-50 peak, but can occur any age
Term
primary problem in RA
Definition
the synovium
-space within capsule that nourishes cells of joint
Term
inflammation caused by..
Definition
infiltration of inflammatory mediators
-lymphocytes, macrophages, cytokines
Term
pannus

more potent
Term
a common use of corticosteroids in RA
Definition
as a bridge to another treatment form
Term
corticosteroid MOA
Definition
enters cell, binds steroid receptor
alters transcription ~20%
-less IL-2, T-cell prolif, PGE and leukotriene synthesis

increased appetite
nervousness, insomnia
*delayed wound healing
Term
long term effects

osteonecrosis
osteoporosis, bone demin.
increased infection
adrenal insufficiency (bc exogenous steroid)
Term
secondary adrenal insufficiency

exogenous steroid means less ACTH produced
inability to synthesize cortisol levels
need MORE steroid prior to surgery
may lead to hypotension, shock, fever, nausea, vomiting, fatigue, hypoglycemia

leflunamide (arava)
-PO, 20mg per day
-long half-life (can be there for 2 yrs)
Term
drug used in organ transplatation, also used in RA

etanercept MOA
Definition
a TNF antagonist
-binds tnf to prevent it from binding receptor
Term
infliximab and adalimumab MOA
Definition
anti-TNF antibody
binds TNF-alpha (thinks its an antigen)
-can be rejected by patient's immune
Term
adalimumab or infliximab is more likely to produce immune reaction?
Definition
infliximab is...
adalimumab is a fully-human antibody, whereas infliximab is from a mouse

blocks T-cell activation
avoid with TNF-alpha antagonists

-decrease joint destruction
-less Ab production
Term
treatment method of RA
Definition
initial corticosteroids
put on DMARD
