Spondyloarthropathies Lecture Powerpoint Flashcards
Spondyloarthropathies definition
Family of inflammatory arthropathies characterized by axial skeletal involvement, peripheral arhtropathy, enthesitis, dactylitis, and extra articular manifestations in genetically predisposed individuals
Common features of the spondyloarthropathies (5)
- association with the HLA-B27 gene
- Enthesitis
- inflammatory back pain (gets better with exercise, stiff in morning, younger person)
- extra-articular manifestations
- family aggregation
Ankylosing spondylitis clinical findings (3)
- age of onset late childhood to young adulthood
- long delay in diagnosis due to insidious onset of symptoms
- male predominant
Ankylosing spondylitis physical exam findings (6)
- tenderness over sacroiliac joints
- restricted motion (schober’s maneuver)
- decreased chest expansion
- decreased cervical spine motion
- peripheral arthritis and enthesitis
- extra articular manifestations
Schober’s maneuver
Test for ankylosing spondylitis, while standing, make a mark at sacral dimples and measure 10cm to make another mark, have patient bend forward and touch toes, measure distance between marks, >15cm is normal, excursion is decreased in ankylosing spondylitis
Radiologic evals of ankylosing spondylitis (2)
- radiographs displaying sacroilitiis, spondylitis, bamboo spine (late stage, see squaring off of vertebrae) and entheses (periosteal new born formation and erosions)
- MRI scan if still uncertain
Sacroilitis radiographic finding
See irregular border, sclerosis on either side of the joint indicating presence of sacroilitis (typically bilateral in ankylosing spondyliis)
Areas where enthesopathies are more likely to occur (4)
- heel (achilles tendon insertion on calcaneous)
- knee (superior and inferior aspect of patella)
- foot
- back and buttocks (iliac spines and crest, ischial tuberosity)
Extra-articular manifestations of ankylosing spondylitis (6)
- acute anterior uveitis
- apical pleural thickening and fibrosis
- aortic insufficiency (diastolic murmur)
- amyloidosis of kidney
- neurologic complications of severe spinal disease
- prostatitis or inflammatory bowel disease
Psoriatic arthritis clinical manifestations (5)
- asymmetric oligoarthritis
- distal interphalangeal joints predominantly
- severe deforming arthritis (arthritis mutilans)
- rheumatoid like arthritis with negative RF
- spondylitis (large asymmetrical bulky syndesmophytes opposed to the thin symmetrical ones in ankylosing spondylitis)
Reactive arthritis (reiter’s syndrome) diagnostic criteria (4)
- seronegative asymmetric oligoarticular arthritis as well as
- urethritis/cervicitis
- dysentary
- inflammatory eye disease conjunctivitis or uveitis
Possible infectious etiologies of reactive arthritis (3)
- genitourinary dz
- GI disease
- lyme disease
- genetically predisposed individuals often with HLAB27
Musculosekeltal manifestations of reactive arthritis (3)
- Asymmetric oligoarthritis predominantly of lower extremities
- sacroilitis usually asymmetric
- enthesitis
Extra-articular manifestations of reactive arthritis (4)
- urethritis
- conjunctivitis or uveitis
- aortic insufficiency
- pleuritis and infiltrates
Management of spondyloarthropathies (8)
- NSAIDS and cox2 inhibitors effective for inflammatory symptoms
- sulfasalazine
- corticosteroids
- methotrexate
- apremilast
- bDMARDS
- PT
- orthopedic surgery
