[Physiology and dynamics of uric acid in hyperuricemia]

Abstract

Gout is a type of inflammatory arthritis that is triggered by the crystallization of monosodium urate (MSU) within the joints and is often associated with hyperuricemia. Further understanding the physiology and dynamics of uric acid in human is required to make sure the disease mechanism of both gout and hyperuricemia in clinic. The amount of urate in the body consists urate pool, and which depends on the balance between dietary intake, synthesis, and excretion. Uric acid is a weak acid that exists largely as MSU, the ionized form, in urate pool at physiologic pH. But the solubility of MSU is influenced of pH, temperature and protein of blood and tissue.
