In a randomized double-blind study of 227 patients with an inadequate response to allopurinol, the addition of lesinurad to the prestudy allopurinol dose resulted in significant mean reductions of serum uric acid levels from baseline. Levels decreased 16%, 22%, and 30% with lesurinad doses of 200, 400, and 600 mg, respectively. In comparison, patients receiving placebo demonstrated a mean 3% increase in serum uric acid levels (P <, all doses vs placebo). Similar results were observed in patients with mild or moderate renal insufficiency. [ 146 ]
Hyperuricemia is a classic feature of gout, but nearly half of the time gout occurs without hyperuricemia and most people with raised uric acid levels never develop gout.   Thus, the diagnostic utility of measuring uric acid levels is limited.  Hyperuricemia is defined as a plasma urate level greater than 420 μmol/l ( mg/dl) in males and 360 μmol/l ( mg/dl) in females.  Other blood tests commonly performed are white blood cell count , electrolytes , kidney function and erythrocyte sedimentation rate (ESR). However, both the white blood cells and ESR may be elevated due to gout in the absence of infection.   A white blood cell count as high as ×10 9 /l (40,000/mm 3 ) has been documented. 
I have a suspicion, after reading many of your notes on injectable steroids, that I seem to have developed a type of “tendonitis” in my upper arms due to multiple elbow steroid injections. I have had 4 in my left elbow (worst arm) and 2 in my right, about 5yrs ago. I have been having this tendon problem for about one year now, and not one doctor can figure out what’s wrong. One actually said “it seems like tendonitis”, but no cause or cure was suggested. The steroid injections is the only common denominator here. The right arm is affected as well, but not nearly to the degree of the left (and I’m right handed, so maybe the strong arm is less affected, plus I only had 2 injections there). Is there hope for acute tendonitis in my bicep/tricep area?
