Fucoidan dose-dependently alleviated hyperuricemia and modulated gut microbiota in mice
The global incidence of hyperuricemia (HUA) is gradually increasing, and HUA poses a severe threat to human health. Between 25% and 50% of HUA patients are not effectively treated with current clinical medications due to drug contraindications or severe adverse reactions. Therefore, novel safe and effective uric acid-lowering products are needed. Fucoidan is a naturally derived polysaccharide containing sulfate groups exclusively found in brown algae. Although there are reports on the anti-HUA effects of fucoidan, the simultaneous regulation of gut microbiota by anti-HUA still needs to be fully understood. In this study, potassium oxonate (PO) and hypoxanthine-induced HUA model mice were treated with 100, 200 and 400 mg/kg fucoidan (from Laminaria japonica) for 14 days. The levels associated with HUA were quantified using assay kits to assess fucoidan intervention. 16S rRNA gene sequencing was used to analyze the effects of fucoidan in mice with HUA. The results showed that fucoidan reduced serum uric acid and urea nitrogen levels in a dose-dependent manner, and serum creatinine levels in the 200 and 400 mg/kg fucoidan groups were similar to those in the control group. It decreased the expression of uric acid metabolic protein levels of xanthine oxidase (XOD), adenosine deaminase (ADA), and glucose transporter (GLUT9) and increased ATP binding cassette subfamily G member 2 (ABCG2) protein expression. 16S rRNA gene sequencing revealed that the richness (Chao and Ace indices) and diversity (Shannon and Simpson indices) of the gut microbiota in model mice decreased, whereas supplementation with fucoidan alleviated gut microbiota dysbiosis in HUA model mice, leading to a gradual approach of α-diversity and β-diversity towards the control mice. Additionally, fucoidan supplementation significantly increased the abundance of beneficial bacteria, which are negatively correlated with the HUA-associated phenotypes, reassuring the positive effects of fucoidan on gut health. This study proposed that fucoidan can be considered a potential candidate for preventing and treating HUA.

Could long sought-after support for type 1 diabetes be as close as your kitchen cupboard? An accumulating body of scientific research appears to point in exactly that direction
with over 2000 years of history in folk medicine, is known for its sweet taste and neutral nature. It is believed to nourish the lungs, strengthen the kidneys, and replenish essence and qi by acting on the lung and kidney meridians. Modern preparations of Cordyceps sinensis, such as Bailing capsules, are made from artificially fermented Cordyceps sinensis powder. Research has demonstrated the ability of Cordyceps sinensis to regulate immunity, reduce inflammation, and combat fibrosis. This article reviews the pharmacological mechanisms of Cordyceps sinensis in treating CKD, highlighting its anti-inflammatory, immunomodulatory, and renal function-enhancing effects. Clinical studies have shown that Cordyceps sinensis can lower inflammatory markers, improve kidney function, and exhibit synergistic effects when combined with angiotensin receptor blockers (ARBs) and other medications. Additionally, it is considered safe for use, making it a promising option for treating CKD in traditional Chinese medicine....

Fucoidan Supplementation Relieved Kidney Injury and Modulated Intestinal Homeostasis in Hyperuricemia Mice | Journal of Agricultural and Food Chemistry
Hyperuricemia is a metabolic disease characterized by an excessively increased level of uric acid (UA) in the blood, with an increasing prevalence and often associated with kidney damage. Gut microbiota and endotoxins of gut origin are key mediators in the gut–kidney axis that can cause renal impairment. The study was to reveal the protective effects of fucoidan on renal injury caused by hyperuricemia. The hyperuricemia model was established in C57BL/6J mice. After 10 weeks of fucoidan supplementation, we found that the levels of serum UA and creatinine were reduced, and the levels of renal tumor necrosis factor α, interleukin-18 (IL-18), IL-6, and interleukin-1β (IL-1β) were also decreased. Fucoidan inhibited the expressions of phosphorylated NF-κB p65, NLRP3, and activated caspase-1 in the kidneys. Fucoidan also regulated the expressions of Bcl-2 family proteins and decreased the activation of caspase-3, thereby exerting antiapoptotic effect. In addition, fucoidan could reduce the expressions of glucose transporter 9 (GLUT9) and urate transporter 1 (URAT1) proteins, thereby promoting the excretion of UA from the kidneys. Moreover, the protective effect of fucoidan on renal injury may be related to maintaining intestinal homeostasis. Fucoidan reduced serum lipopolysaccharide and improved the intestinal mucosal barrier function. Fucoidan decreased the abundances of Blautia, Muribaculaceae, and Dubosiella, and increased the abundances of Lactobacillus. High-dose fucoidan supplementation increased the content of butyric acid and enhanced the expression of ATP binding box transporter G2 (ABCG2) via the AMPK/AKT/CREB pathway in ileum. Conclusion: Fucoidan could protect against hyperuricemia-induced renal injury by inhibiting renal inflammation and apoptosis and modulating intestinal homeostasis in hyperuricemia mice.

A Review of Dietary Supplement–Induced Renal Dysfunction : Clinical Journal of the American Society of Nephrology
ely inquire. Annually, thousands of dietary supplement–induced adverse events are reported to Poison Control Centers nationwide. CAM manufacturers are not responsible for proving safety and efficacy, because the Food and Drug Administration does not regulate them. However, concern exists surrounding the safety of CAM. A literature search using MEDLINE and EMBASE was undertaken to explore the impact of CAM on renal function. English-language studies and case reports were selected for inclusion but were limited to those that consisted of human subjects, both adult and pediatric. This review provides details on dietary supplements that have been associated with renal dysfunction and focuses on 17 dietary supplements that have been associated with direct renal injury, CAM-induced immune-mediated nephrotoxicity, nephrolithiasis, rhabdomyolysis with acute renal injury, and hepatorenal syndrome. It is concluded that it is imperative that use of dietary supplements be monitored closely in all patients. Health care practitioners must take an active role in identifying patients who are using CAM and provide appropriate patient education....
