Effect of Curcumin on Serum Urate in Asymptomatic Hyperuricemia: A Randomized Placebo-Controlled Trial.
Hyperuricemia leads to gout and renal complications and may increase cardiovascular risk. Curcumin inhibits xanthine oxidase and increases uricosuric activity and, as a result, decreases serum urate (SU). This randomized controlled trial aimed to determine the effects of curcumin versus placebo on SU in subjects with asymptomatic hyperuricemia (SU level ≥ 6 mg/dL in women or ≥ 7 mg/dL in men).. Thirty-nine subjects with persistent hyperuricemia were randomized to receive curcumin (500-mg capsules twice daily, 20 subjects) or placebo (19 subjects). Primary outcome was the difference between SU before and 8 weeks after randomization. Secondary outcomes were differences between urine uric acid (UUA) clearance, fasting plasma glucose (FPG), and lipid profiles before and 8 weeks after randomization and adverse events.. Out of 39 subjects, there were no differences at baseline SU, UUA clearance, FPG, lipid profiles, and demographics between curcumin and placebo groups. After 8 weeks, SU was significantly decreased in both groups (6.9% in curcumin group,. Curcumin was not superior to placebo in reducing serum urate and in increasing UUA clearance.

Curcumin attenuates MSU crystal-induced inflammation by inhibiting the degradation of IκBα and blocking mitochondrial damage.
Gouty arthritis is characterized by the deposition of monosodium urate (MSU) within synovial joints and tissues due to increased urate concentrations. In this study, we explored the effect of the natural compound curcumin on the MSU crystal-stimulated inflammatory response.. THP-1-derived macrophages and murine RAW264.7 macrophages were pretreated with curcumin for 1 h and then stimulated with MSU suspensions for 24 h. The protein level of TLR4, MyD88, and IκBα, the activation of the NF-κB signaling pathway, the expression of the NF-κB downstream inflammatory cytokines, and the activity of NLRP3 inflammasome were measured by western blotting and ELISA. THP-1 and RAW264.7 cells were loaded with MitoTracker Green to measure mitochondrial content, and MitoTracker Red to detect mitochondrial membrane potential. To measure mitochondrial reactive oxygen species (ROS) levels, cells were loaded with MitoSOX Red, which is a mitochondrial superoxide indicator. The effects of curcumin on mouse models of acute gout induced by the injection of MSU crystals into the footpad and synovial space of the ankle, paw and ankle joint swelling, lymphocyte infiltration, and MPO activity were evaluated.. Curcumin treatment markedly inhibited the degradation of IκBα, the activation of NF-κB signaling pathway, and the expression levels of the NF-κB downstream inflammatory genes such as IL-1β, IL-6, TNF-α, COX-2, and PGE2 in the MSU-stimulated THP-1-derived macrophages. Curcumin administration protected THP-1 and RAW264.7 cells from MSU induced mitochondrial damage through preventing mitochondrial membrane potential reduction, decreasing mitochondria ROS, and then inhibited the activity of NLRP3 inflammasome. Intraperitoneal administration of curcumin alleviated MSU crystal-induced paw and ankle joint swelling, inflammatory cell infiltration, and MPO activity in mouse models of acute gout. These results correlated with the inhibition of the degradation of IκBα, the phosphorylation levels of NF-κB subunits (p65 and p50), and the activity of NLRP3 inflammasome.. Curcumin administration effectively alleviated MSU-induced inflammation by suppressing the degradation of IκBα, the activation NF-κB signaling pathway, the damage of mitochondria, and the activity of NLRP3 inflammasome. Our results provide a new strategy in which curcumin therapy may be helpful in the prevention of acute episodes of gout.
