  • 3. 脊椎關節炎Spondyloarthritis Diagnostic clues for SpA1. 僵直性脊椎炎(Ankylosing Spondylitis) 1. 發炎性下背痛:薦腸關節炎(sacroiliitis)2. 反應性關節炎(Reactive arthritis, 過去 及脊椎炎(spondylitis) 。 稱為萊特氏症候群Reiter syndrome) 2. 接骨點炎 (enthesitis) 。3. 乾癬性關節炎(Psoriatic arthritis) 3. 不對稱性的下肢關節炎。4. 發炎性大腸疾病(Enteropathic 4. 與HLA-B27基因有關聯。 arthropathy)5. 未分化型脊椎關節炎 5. 有關節外的表徵:如乾癬、腸炎、尿道 (Undifferentiated spondyloarthritis) 炎、葡萄膜炎。 Finger to floor test Enthesopathy, dactylitis Enthesopathy, Posterior SI compression test Patrick test 3
  • 4. European Spondyloarthropathy Study Group Classification Criteria for Spondyloarthropathy Extra-articular Extra- (ESSG, 1991) manifestations of SpA Inflammatory spinal pain OR Peripheral synovitis (asymmetrical or lower limb) PLUS any one of the following: • alternate buttock pain • psoriasis • sacroiliitis • inflammatory bowel disease • enthesopathy • urethritis or cervicitis or acute diarrhea Psoriasis Uveitis • positive family history Dougadous, 1991International Congress on Spondyloarthropathy Gent, Belgium X ray finding of spondylitis Anterior Squaring of vetebral bodies Corner enthesitis Lt: AS with bamboo spine Rt: Diffuse idiopathic skeletal Syndesmophyte Hyperostosis(DISH) 4
  • 5. Three Problems of the MNY criteria1. Ignore the other features associated with SpA, e.g. SpA, enthesitis, psoriasis and uveitis enthesitis,2. Ignore the role of HLA-B27 in HLA- diagnosis3. Too much reliance on plain X-ray X- changes of sacroiliiac joints HLA-B27, when to test? HLA- When you are not so sure about the diagnosis of SpA.

Chronic low back pain (5% probability of axial SpA) Inflammatory back pain yes (14% probability) no (<2% probability) Presence of other SpA-features: heel pain (enthesitis), dactylitis, uveitis, positive family history, Crohn‘disease, s alternating buttock pain, psoriasis, asymmetrical arthritis, positive response to NSAIDs, No further testing unless SpA is strongly suspected acute phase reactants (elevated ESR/CRP) because of the presence of other features.  SpA features 3 1-2 SpA feature(s) no SpA feature (80-95%) (35-70%)* (14%) X-rays pos neg HLA-27 HLA-27 pos neg pos neg (80-90%) (<10%) (59%) (<2%) MRI Consider other pos neg diagnosis (80-95%) (<15%) Consider other diagnosis AS Axial SpA** Axial SpA**Take home messageDiagnosis of SpA Thank you Clinical manifestations –Articular: axial, peripheral Articular: –Extra-articular Extra- 魏正宗 MD,PhD.
