  • Why did the ACR come up with recommendations – as other societies had published their guidelines much earlier (e.q. EULAR, British Society of Rheumatology, etc)? The goal was not to create new classification system or a paradigm shift in the way we manage gout. But rather to appraise current evidence on what is effective and safe to give to gout patients and to summarize these to reflect the best standards of care. The recommendations did not cover the diagnosis of patients with gout but instead focuses on how we should be managing gout. It assumes that a correct diagnosis of gout was made. That a thorough evaluation of co-morbid conditions was carried – particularly those which impact on how gout care would change. And a review of medications to evaluate for potential drug-drug interaction.
  • Rather than evaluate the strength of the recommendation, the ACR merely provides us with an assessment of the quality of evidence available to support a recommendation. It does not follow that a recommendation having a higher level of evidence would be better than something having lower quality. Nor would a lower level of evidence mean that an intervention should not be considered.
  • Severity is assessed by using the Pain VAS. &lt;4 mild, 5-6 moderate, &gt;7 severe.Duration is defined by the time from the onset of signs and symptoms of gout. &lt;12 hours – early, 12-36 hours – established, &gt;36 hours – lateFrequency is based on the number of flares occuring in a year. &lt;1 – infrequent, 2-6 frequent, &gt;7 very frequent
  • Large joints – ankles, knees, hips, elbows, wrists and shouldersRegions - forefoot, midfoot, hindfoot, knee, hip, wrist, elbow, shoulder
  • Simple tophi – lack of drainage, lack of aggressive mass or destructive effects, low risk of tophus infection, stable in size/ slow growth, lack of severe chronic tophaceous joint inflammationComplicated tophi – drainage, aggressive mass or destructive effects, high risk of infection, very rapid growth and with severe chronic tophaceous inflammation.
  • Recommended doses: Naproxen 500 mg BID, Indomethacin 50 mg TID, Sulindac 200 mg BIDBased on an RCT (which Dr JLY was part of) the dosing of Celecoxib was 800 mg initially then another 400 mg on D1 then 400 mg BID from D2 – D8
  • All life style changes – weight loss and exercise, healthy overall diet, smoking cessation, hydration- have Evidence Level C.
  • Consider increased OFI and urine alkalinization when using uricosurics
  • Start at low dose to reduce gout flares associated with ULT initiation and as risk reduction for AHS
  • Did not recommend Allopurinol Maintenance Dosing based on Renal Function (C)
  • Uricosurics - (probenecid, losartan, fenofibrate) – sulfinpyrazone (Available in the Phils) and benzbromarone were not recommended simply due to paucity of literature on their utility in such setting
