Although dietary, genetic, or disease-related excesses in urate production may contribute to hyperuricemia, impaired renal excretion of uric acid is the dominant cause of hyperuricemia in the majority of patients with gout. The aims of this review are to highlight exciting and clinically pertinent advances in our understanding of how uric acid is reabsorbed by the kidney under the regulation of...
Of 50 patients with urinary calculi, upper tract stones were common between 15-44 and lower tract stones between 0-14 and above 44 years of age. Urinary calculi contained calcium, phosphate, oxalate, urate/uric acid, ammonium, magnesium and carbonate. The frequency of occurrence of each of these radicals in sixty stones was 93.33, 83.33, 61.67, 51.67, 25.00 and 13.33% respectively. Five (27.78%...
To clarify the physiological and pathophysiological roles of intestinal urate excretion via ABCG2 in humans, we genotyped ABCG2 dysfunctional common variants, Q126X (rs72552713) and Q141K (rs2231142), in end-stage renal disease (hemodialysis) and acute gastroenteritis patients, respectively. ABCG2 dysfunction markedly increased serum uric acid (SUA) levels in 106 hemodialysis patients (P = 1.1 ...
Gout is a metabolic disorder characterized by elevated uric acid levels in the body, associated with painful arthritis, tophi and nephropathy. The most frequently used pharmacologic urate lowering strategies involve reducing urate production with a xanthine oxidase inhibitor and enhancing urinary excretion of uric acid with a uricosuric agent. Urate lowering agents are limited in number, availa...
Gout is a chronic rheumatic disease resulting from accumulation of monosodium urate crystals in tissues. The most important risk factor for the disease is hyperuricaemia. Precipitation of uric acid in the joint in the form of monosodium urate crystals is the main factor responsible for triggering attacks of arthritis. Tophi occur as a result of urate crystals that precipitate into joints and su...
Despite a sound understanding of the synthetic and metabolic pathways that control serum uric acid levels, clinicians have been limited to a few urate lowering agents and one urate synthesis inhibitor since the development of allopurinol in 1956. Febuxostat (Uloric) became the second urate synthesis inhibitor when the Food and Drug Administration (FDA) approved it in early 2009. The role of feb...
Gout is a chronic disease in which excessively high levels of serum urate (hyperuricemia) result in tissue depositions of sodium urate crystals and intermittent inflammatory attacks. Patients who have gout frequently experience a range of comorbidities, which complicates management and affects long-term prognosis. We review some of the more important of these comorbidities and consider the exte...
© 2013 The Authors. doi: 10.2340/00015555-1393 Journal Compilation © 2013 Acta Dermato-Venereologica. ISSN 0001-5555 Gout is a clinical syndrome presenting with recurrent, painful arthritis caused by deposition of monosodium urate. Urate crystal deposits are usually detected in the synovial membranes, joint capsules, articular cartilage, and periarticular tissue, and, rarely, in extra-articular...
Urate oxidase is an endogenous enzyme found in most mammals but not in humans. Urate oxidase catalyzes the enzymatic oxidation of uric acid into allantoin, a metabolite that is 5–10 times more soluble in urine than uric acid. With complementary DNA technology it is possible to produce large quantities of the pure recombinant protein [1]. Rasburicase (RS), a recombinant form of urate oxidase, ha...
