Diagnosis: Clinical - acute gout flare
• symptoms : pain, swelling, heat, redness, and difficulty moving the affected joint.
• severe pain usually peaks within 24 h
•The most common site of involvement is the first metatarsophalangeal joint, other sites in the foot and ankle are also commonly affected
•Triggers for flares include acute medical or surgical illness, dehydration, or dietary factors such as alcohol intake and purine-rich foods

Diagnosis: The gold standard
• Aspirate joint/tophi
• MSU crystal
sometimes >50 000 cells per mm3

Serum urate testing
• is useful to assist with clinical diagnosis of gout in symptomatic individuals
• But hyperuricaemia alone is NOT sufficient for diagnosis (most people with hyperuricaemiado not have gout.)
• Importantly, serum urate concentrations can fall into the normal range during an acute flare (40%, ACTH –uricosuric effect), and if gout diagnosis is uncertain, serum urate should be retested after the flare has resolved.

Management of acute gout flares
• Option1- monotherapy
– NSAID- inflammatory dose, shortest period, beware of renal/GI effect
– Colchicine –if attack<12 hr,
• 1-2 tab stat and then 1 tab 1 hour later (evidence B), or
• 1 tab q 6-8 hr (if normal GFR) (high dose is not recommended)
– Medium dose glucocorticoid- 30-35 mg/d split 5 days and then taper within 1 wk(beware of rebound effect, hyperglycemia)
– (intraarticular steroid injection-selected case)
• Option2- combination therapy eg. Colchicine +NSAID, colchicine + steroid

• High dose: 2 tab po stat, 1 tab q hr for 6 hr (4.8 mg over 6 hr)
• Low dose: 2 tab po stat, 1 tab 1 hr later, followed by placebo doses every hour for 5 hours (1.8 mg over 1 hour)

Combination therapy- gout flare (evidence C)
• Initial combination is appropriate for an acute , severe gout attack, particularly with involvement of multiple large joints or polyarticular arthritis Acceptable combination therapy
1. Colchicine and NSAID
2. Colchicine and oral steroid
3. IA steroid with all other modalities
• For patients not responding adequately to initial monotherapy, adding a second agents is acceptable
Colchicine: full dose or prophylactic dose
