Spondyloarthrritis Flashcards
seronegative spondyloarthropathies
ankylosing spondylitis
psoriatic arthritis
reactive arthritis
enteropathic arthritis
characteristic features of apondyloarthropathies
seronegative
association with HLA B27
sacroliths
spondylitis
peripheral arthritis
enthesitis
psoriasiform skin and nail lesions
anterior uveitis
chronic GI inflammation
chronic Genitourinary inflammation
criteria for diagnosis of Ank Spond
- limited lumber motion
- low back pain for 3 months improved by exercise, not improved by rest
- reduced chest expansion
- radiographic sacrolitis
ank spond if criteria 4 plus 1, 2 or 3
role of HLA-B27 in the pathogenesis of any spond
HLA-B27 misfiling
arthogenic peptide theory
formation of B 27 homodimers
sequence of structural damage in and spond
- inflammation
- erosive damage
- repair
- new bone formation (too much new bone)
characteristics of back pain in ank spond
insidious onset of back pain before 40 years
duration longer than 3 months
associated with morning stiffness
decreases with exercise
response to NSAIDs
ank spons mostly affects
M>F
2.5:1
reactive arthritis
occurs predominantly men in young-mod age
acute onset
may occur with infectious triggers
psoriatic arthritis
occurs equally between males and females of young-middle aged with variable onset
enteropathic arthritis
occurs equally in males and females of young-middle age with variable inset
skeletal features of ank spend
axial arthritis eg. sacroiliitis and spondylitis
arthritis of girdle joints (hips and shoulders)
peripheral arthritis uncommon
may also cause enthesitis, osteoporosis, vertebral fractures, spondylodiscitis, pseudoarthrosis
extrraskeletal features of ask spond
acute anterior uveitis
cardiovascular involvement
pulmonary involvement
cauda equina syndrome
enteric mucosal lesions
amyloidosis
testing spinal mobility
patient standing erect
mark an imaginary line connecting both posterior superior iliac spines
another mark placed 10cm above
the patient bends forward maximally, measure the distance between the two marks
report increase in distance
5 subtypes of psoriatic arthritis
DIP predominant
Oligoarticular
Polyarticular
Spondyloarrthropathy
arthritis mutilans
describe reactive arthritis
a sterile joint infection that develops after a distant infection
