inflamed synovium, pannus, loss of cartilage, fibrous tissue (ankylosis) and pannus-filled erosion?
|
|
Etiology of RA includes no single agent that's responsible. It can be a combination of _______ and _________.
|
genetics and environment
|
|
What's the coding system called that tells if you're susceptible to RA?
|
HLA system
|
|
T/F? RA appears to be an immune response initiated by an antigen.
|
true
|
|
What are some possible sources of this antigen for RA?
|
==EBV (Epstein-Barr virus)
==Parvovirus infection (small DNA viruses) ==bacteria or microplasms |
|
Eventually normal antibodies somehow become __________.
|
autoantibodies
|
|
These tranformed autoantibodies are termed ____________--antibodies against ____, ____, ____ and form _______________.
|
rheumatoid factors (RF's)
IgG, IgM, occas. IgA and form immune complexes. |
|
T/F? Some of the immune complexes that form in the RA response include activation of T helper cells and the release of cytokines.
|
true
|
|
RA main be due to some _______ immune responses to an unidentified antigen in genetically susceptible individuals.
|
aberrant
|
|
T/F? The release of cytokines or T helper cells eventually gets antibody formed to react with fragments from what were normal antibodies?
|
true
|
|
____ bind with their target self antigens in blood and form complexes in blood and _ _________.
|
RF's
synovial membranes |
|
What type of injury is this called?
This has ________ __________ of antigenic material to stimulate the immune response. |
type III
continual production |
|
_____ antibodies also have been demostrated in synovial fluid in patients with RA
|
Anti-collagen
|
|
Synovial inflammation is also termed ________.
|
synovitis
|
|
2 aspects of synovitis include:
|
synovial fluid
synovial membrane |

In the synovial membrane of RA, there is ____a______ infiltration with ___b______ cells and a striking accumulation of new blood vessels (termed ____c_____)
|
a) perivascular
b) mononuclear c) angiogenesis |
|
Synovial membranes ultimately form into what? (a)
This tissue is rich in what? b Can lead to what? c |
a) forms a granulation tissue (pannus)
b)inflammatory cells that secrete enzymes and various mediators of inflam. to destroy cartilage and bone c) eventually leads to join deformity and muscle atrophy |
|
Monocytes/macrophages and fibroblasts release ______ and _______ to resorb bone and connective tissue.
|
proteases and chemotactic factors
|
|
What's the term that describes the loss of functional synovial membrane vascularity DECREASING as granulation tissue and fibrosis develops called?
What does this cause? What does this stimulate? |
-hypoxemia from diminished blood flow.
-acidosis -stimulates release of hydrolytic enzymes--gets even more damaged. |
|
What plays a major role in the amplification of the immune response in RA?
What does this lead to? What does this serve as? |
-immune complexes (containing RF)
-proliverative synovitis -chemotaxis force |
|
What is another source of amplification of inflammatory condition?
What does this lead to? What else is activated? |
-PMN's
-leads to aggregation, degranulation, and superoxide anion generation -other inflammatory pathways are activated (HF, kinins, complement) |
