In medicine, gout is a "hereditary metabolic disorder characterized by recurrent acute arthritis, hyperuricemia and deposition of sodium urate in and around the joints, sometimes with formation of uric acid calculi."[1]

Treatment

A randomized controlled trial found that patients who used ice packs had better relief of pain with no negative side effects.[2]


Comparison of NSAID and steroids for acute gout

Janssens et al 2008[3] NSAID tended to be better
Man et al 2007[4] Steroids faster reduction in pain


Randomized controlled trials find similar benefit from non-steroidal anti-inflammatory agents and oral glucocorticoids. In the first trial, less adverse drug reactions occurred in the glucocorticoids group.[4] In the non-steroidal anti-inflammatory agents group, each patient initially received diclofenac (75 mg) intramuscularly, indomethacin 50 mg orally, and acetaminophen 1 g orally. The patient was received a 5-days of indomethacin (50 mg orally every 8 hours for 2 days, followed by indomethacin 25 mg every 8 hours for 3 days), and acetaminophen 1 g every 6 hours as needed. The glucocorticoids patients received prednisolone 30 mg orally, and acetaminophen 1 g orally. The patient was then given prednisolone 30 mg orally once per day for five days.

In the second randomized controlled trial equal effect resulted from prednisolone 35 mg orally per day or naproxen 500 mg orally per day.[3]

Colchicine

Colchicine is better than placebo according to a systematic review by the Cochrane Collaboration[5] that found a single randomized controlled trial[6].

Prognosis

Acute flares

Without treatment, one third of flares improve within 2 days.[6]

Prevention

Diet

Avoiding products with high fructose such as sugary soft drinks (sweetened with high fructose corn syrup), and other high-fructose products, such as fruit juice, apples, and oranges may help.[7]

Medications

Xanthine oxidase inhibitors

Allopurinol can reduce frequency of attacks. However, when allopurinol is started, colchicine 0.6 mg twice daily should also be used. In a randomized controlled trial, co-treatment with colchicine 0.6 mg twice daily while allopurinol was tapered up from 100 mg/day until 3 months after the serum urate concentration < 6.5 mg/dl, reduced flares of gout from 77% in the placebo broup to 33% with colchicine prophylaxis. Most of these patients had tophi.[8]

Allopurinol should be increased as possible to achieve a goal serum urate of <6 mg/dl (360 micromoles/liter).[9]

Febuxostat, a non-purine inhibitor, is equally effective as allopurinol when compared in a randomized controlled trial.[10]

Uricosuric agents
