Topic 10 - Inflammatory Arthritides Flashcards
Ther are over 100 different types of ____________ ___________, and they affect all age groups. All cause inflammatory and degenerative changes in connective tissue and joints.
Inflammatory Arthritides
Inflammatory arthritides can develop as a _______ disorder or as a _________ disorder.
Primary
Secondary
Common ____________ ___________ include:
- Rheumatoid arthritis
- Lupus
- Sjögren’s syndrome
- Juvenile rheumatoid arthritis
- Scleroderma
- Ankylosing spondylitis
- Gout
- Lyme disease infectious arthritis
- Reiter’s syndrome
Inflammatory Arthritides
A chronic, systemic inflammatory disease of joints and connective tissue that affects females more than males. The disease can occur at any stage in life, but prevalence increases with age.
Rheumatoid Arthritis (RA)
Peak incidence of RA is _______ aged ___ to ___ years.
Females
40-60 years
While idiopathic, RA is thought to be __________ in origin. 70-80% of RA sufferers test positive for an auto-antibody called __________ factor.
Autoimmune
Rheumatoid (RH)
RH factor combines with ____ to form ______ complexes. Along with complement components, these are found in synovium, synovial fluid and extra-articular lesions of person with RA.
IgG
Immune
With RA, the ______ system attacks the immune complexes and releases _______ that destroy articular cartilage.
Immune
Enzymes
Characteristics of ______________ include:
- Age of onset usually after age 40
- Usually develops slowly over many years in response to mechanical stress
- Cartilage degeneration, altered joint architecture & osteophyte formation
- Can affect any joint (usually weight bearing joints & usually asymmetrical)
- Morning stiffness (< 30 mins), increased joint pain with weight bearing/after periods of immobility & crepitus/loss of ROM
- No systemic S/S
Osteoarthritis
Characteristics of __________ _________ include:
- Age of onset between 15-50 years
- May develop suddenly, within weeks/months
- Inflammatory synovitis & irreversible structural damage to cartilage/bone
- Usually affects many joints bilaterally (e.g. MCPs, PIPs of hands, wrist, elbow, shoulder, c-spine, MTPs, talonavicular, ankles)
- Redness, warmth, swelling, prolonged morning stiffness (> 1 hour)
- General feeling of sickness, fatigue, myalgias, arthralgias, weight loss, rheumatoid nodules
- May have ocular, respiratory, hematological and cardiac symptoms
Rheumatoid Arthritis
What are the 4 stages of RA?
1) Synovitis
2) Pannus Formation
3) Fibrosis
4) Bony Ankylosis
A stage of RA where there is inflammation of the synovial membrane and joint effusion.
Synovitis
A stage of RA characterized by an abnormal form of granulation tissue in which as extensive network of new blood vessels forms in the synovium, which contributes to inflammation. ______ _________ extends to the joint margins and enzymes are released that destroy articular cartilage/bone.
Pannus Formation
A stage of RA where intra-articular adhesions form as a result of the inflammation. These will lead to decreased ROM of the associated joints.
Fibrosis
A stage of RA characterized by calcification of the panni and fibrous tissue. This leads to joint fusion which further leads to deformity and disuse atrophy.
Bony Ankylosis
T/F - Flare up and remission are not common with RA.
False - Flare up and remission ARE common with RA.
During an RA flare up, there will be generalized __________, fatigue and associated weight loss.
Arthralgia
T/F - RA presentation is usually bilateral and symmetrical, involving more than one joint.
True
RA patients often feel _________ in the morning that lasts for about an hour or more.
Stiffness
Progressive joint destruction with RA may lead to ___________ and possible subluxation.
Instability
Rheumatoid _______ may appear with RA, as well as fibrosis of muscles with associated weakness and atrophy.
Nodules
_________ in muscle strength and alterations in line of pull of muscles/tendons add to deforming forces associated with RA.
Asymmetry
