Biomimetic bioreactor for potentiated uricase replacement therapy in hyperuricemia and gout.
Front Bioeng Biotechnol
January 2025
Department of Rheumatology and Immunology, The Third Affiliated Hospital of Southern Medical University, Institute of Clinical Immunology, Academy of Orthopedics, Guangzhou, Guangdong, China.
Introduction: Uricase replacement therapy is a promising approach for managing hyperuricemia and gout but is hindered by challenges such as short blood circulation time, reduced catalytic activity, and excessive hydrogen peroxide (HO) production. These limitations necessitate innovative strategies to enhance therapeutic efficacy and safety.
Methods: We designed and synthesized RBC@SeMSN@Uri, a red blood cell-coated biomimetic self-cascade bioreactor, which encapsulates uricase (Uri) and a selenium-based nano-scavenger (SeMSN) within RBC membranes.

Humans develop hyperuricemia via decreased urate elimination and excess urate production, consequently promoting monosodium urate crystal deposition and incident gout. Normally, approximately two thirds of urate elimination is renal. However, chronic kidney disease (CKD) and other causes of decreased renal urate elimination drive hyperuricemia in most with gout.

Ticagrelor, an effective antiplatelet for acute coronary syndrome (ACS), may elevate serum uric acid (SUA), potentially causing gout. This study aims to identify risk factors for ticagrelor-induced in-hospital gout in patients with ACS and create a predictive model for clinical use.A total of 1164 patients with ACS treated with ticagrelor (n = 640) or clopidogrel (n = 524) were retrospectively analyzed.

The case of Lumbar spinal stenosis (LSS) combined with tophi due to gout is rarely reported. In the course of our clinic work, we encountered a young male patient who was diagnosed with a history of gout for 5 years and was targeted as LSS combined with gouty tophi, and we would like to share this case. In addition, in order to further investigate the deep mechanism of LSS associated with gout, we obtained the intersecting genes of the two diseases based on a machine learning approach by obtaining the dataset GSE113212 related to LSS from the Gene Expression Omnibus (GEO) database, and the genes related to gout from the human gene database.

Gout is a systemic metabolic disorder caused by elevated uric acid (UA) levels, affecting over 1% of the population. The most common complication of gout is gouty arthritis (GA), characterized by swelling, pain or tenderness in peripheral joints or bursae, which can lead to the formation of tophi. At present, western medicines like colchicine, febuxostat and allopurinol are the primary treatment strategy to alleviate pain and prevent flare-ups in patients with GA, but they have significant side effects and increased mortality risks.
