  • Acute gout is common inflammatory arthritis in the adult US population.

  • 2.
  • Gout results from inflammation caused by precipitation of uric acid crystals from supersaturated extracellular fluid.

Intervention & Comparison
Outcome
Zhang, 2014
Observation
al, n=60
IM betamethasone 7 mg x 1
vs
diclofenac 75 mg BID x 7 days
Betamethasone > diclofenac pain reduction at day 3
Betamethasone = diclofenac pain reduction at day 7
Betamethasone< diclofenac adverse effects
Daoussis, 2013
Observation
al, n=181
IM ACTH 100 units
78% of patients improved after one day after a dose
Minimal impact on blood pressure and serum
potassium
Elevation in fasting blood sugar for 24 hours
Terkeltaub, 2010
RCT, n=184
colchicine 1.8 mg total over 1 hour
vs
colchicine 4.8 mg total over 6 hours
vs
Placebo
Low-dose colchicine and high dose colchicine =
comparable efficacy
Low-dose colchicine safety profile = same as placebo
Man, 2007
RCT, n=90
prednisolone 30 mg/APAP 1g
vs
indomethacin 50 mg/APAP 1 g
Prednisolone/APAP is as effective as oral
indomethacin/acetaminophen in relieving pain but ↓
adverse effects.
Siegel, 1994
RCT, n=31
IM adrenocorticotropic hormone 40
IU
vs
IM triamcinolone acetonide 60 mg
Resolution of all symptoms occurred at an average of 8
days for both groups.
No adverse reactions were noted in either group
11 reinjections in the ACTH group vs 5 reinjections in the
triamcinolone acetonide group
Alloway, 1993
RCT, n=27
Indomethacin 50 mg TID
Vs
IM triamcinolone acetonide 60 mg
Resolution of all symptoms occurred at 8 days for a
patient taking indomethacin vs 7 days with
triamcinolone
Maccagno ,1991
RCT, n=61
etodolac 300 mg BID x 7 days
vs
naproxen 500 mg BID x 7 days
Significant in both treatment groups at each time
intervals
93-97% of patients report improved condition treated
with either agent
