deoxycholic-acid and Hyperuricemia

Morin, one of the most widely distributed flavonoids in plants, has been identified as a potent antihyperuricemic agent. Its poor water solubility and fast in vivo clearance, however, have limited its application in the treatment of hyperuricemia. In this study, a novel amphiphilic polymer (hydroxyethyl starch-deoxycholic acid [HES-DOCA]) was synthesized to overcome these limitations.. The optimized HES-based amphiphilic polymer contained approximately 10 DOCA groups per 100 anhydroglucose units of HES, which can spontaneously self-assemble to form spherical NPs as demonstrated by TEM images. Morin/HES-DOCA-NPs were monodispersed (polydispersity index = 0.05) with a mean diameter of 197 nm and exhibited a zeta potential of -14 mV. The use of DOCA as the polymer's hydrophobic segment enabled high drug loading efficiency (15.6%). After systemic administration, Morin/HES-DOCA-NPs exhibited significantly longer half-life and higher systemic exposure (elimination half-life and area under the plasma concentration-time curve) compared with free drug Morin. In a rat hyperuricemic model, treatment with Morin/HES-DOCA-NPs demonstrated superior therapeutic efficacy over Morin in decreasing serum uric acid level, increasing the uricosuric action, as well as attenuating hyperuricemia-associated inflammation in kidney of rats.. Collectively, these findings suggest that the novel HES-based NP formulation of Morin may have great potential for clinical treatment of hyperuricemia.

Basis on study through integrated comparative assessment of clinical, biochemical survey data revealed that in patients with impaired metabolism of uric acid in a greater percentage of common biliary sludge, a violation of the rheological properties of bile, a violation of cholate-cholesterol ratio index, which indicates an increased risk of bile stones. The study found that despite the high levels of uric acid there is a violation of the spectrum of bile acids, cholic and deoxycholic growth acid reduction taurocholic acid. Thus, application of ursodeoxycholic acid, rosuvastatin and allopurinol in these study patients with NAFLD dosages in combination with hyperuricemia improves the clinical symptoms and normalization of biochemical parameters and normalizes the spectrum of biliary acids.
