Ankylosing Spondylitis typical presentation
<30yo male with gradual onset of back pain, worse at night, relieved by exercise, morning stiffness
Progressive loss of spinal movement, thus decreased thoracic expansion

HLA B27+ve
X-rays: sclerosis, erosions
Calcifications of ligaments
Management for Ankylosing spondylitis
Exercise (intense regiments) Maintain posture and mobility NSAIDs remove pain in 48h TNF-alpha blockers Local steroid injections Surgery: hip replacement
What is enteric arthropathy
IBD, GI bypass, coliac and whipple’s
Treat bowel symptoms (beware NSAIDs)
What is Psoriatic arthritis

Management of Psoriatic arthritis
NSAIDs Sulfasalazine Methotrexate Ciclosporin Anti-TNF agents
Reactive arthritis
Sterile arthritis affecting lower lib after urethritis or dysentery
Chronic or relapsing
Ass/w iritis, keratoderma blenorrhagica, circinate balanitis
Reiter’s syndrome: urethritis, arthritis, conjunctivitis
Tests for Reactive arthritis
ESR
CRP
Culture stool if diarrhoea
X-ray: enthesitis with periosteal reaction
Management of Reactive arthritis
Splint
NSAIDs or topical steroid injections
Sulfasalazine/methotrexate
