After 24 months of allopurinol treatment, serum UA levels were significantly decreased in subjects treated with allopurinol, from 7.8 ± 2.1 mg/dl to 6.0 ± 1.2 mg/dl (P= 0.000), whereas serum UA levels for subjects in the control group remain unchanged throughout the study period (7.3 ± 1.6 mg/dl at baseline and 7.5 ± 1.7 mg/dl at 24 months ) (P= 0.016 between groups and time period) (Table 4). The change in UA levels at 24 months was +0.3 ± 0.27 mg/dl in the control group in comparison to −1.6 ± 0.27 mg/dl in the allopurinol group (P= 0.000) (Figure 2).

How many patients were followed up in the renal clinic in 2007?
One hundred thirty-five patients were followed up in our renal clinic from January 2007 to May 2007 and screened for eligibility to participate in the study. Included subjects had to fulfill the following inclusion criteria: (1) presence of renal disease, defined as having an estimated GFR (eGFR) lower than 60 ml/min; (2) stable clinical condition in terms of no hospitalizations nor cardiovascular events within the 3 months before screening; and (3) stable renal function (baseline serum creatinine had not increased by 50% in the 3 months before screening).
Does renal disease cause hyperuricemia?
In patients with renal disease, there is decreased uric acid (UA) urinary excretion, and whether this will give rise to hyperuricemia depends on the gastrointestinal excretory compensation. By this, the prevalence of elevated serum UA in patients with chronic kidney disease (CKD) is higher (1). Elevated serum UA has been related to increased risk for the development of hypertension and cardiovascular disease (2). Chronic hyperuricemia would stimulate the renin-angiotensin system and inhibit release of endothelial nitric oxide, contributing to renal vasoconstriction and increasing BP, at the same time, high levels of UA may have a pathogenetic role in interstitial inflammation and progression of renal disease (3,4).

Does UA affect cardiovascular mortality?
However, prospective studies are necessary to show that reduction of UA levels prevent cardiovascular events.
Does allopurinol lower UA?
Allopurinol decreases serum UA level by inhibiting the enzyme xanthine oxidase. For animal models of established renal diseases, correction of the hyperuricemic state can significantly improve BP control, decreasing proteinuria and slowing the progression of renal disease (4). There are few data on patients with CKD that confirm these findings.
