Efficacy Study of Acupuncture on Asymptomatic Hyperuricemia

Evaluating the Efficacy of Acupuncture for Patients With Asymptomatic Hyperuricemia (HUA): A Multicenter Randomized Controlled Clinical Trial

hyperuricemia (HUA) is an important risk factor for various chronic diseases, such as gout, and the current treatment programs for HUA are not ideal. It is urgent to find new methods to prevent and treat HUA and to carry out early clinical intervention. Acupuncture is commonly used for the treatment of HUA, while the evidence for its efficacy is still uncertain. This clinical trial aimed to evaluate the efficacy and safety of manual acupuncture for asymptomatic HUA.

This is a multicentre, stratified, randomized, sham-controlled clinical trial. 180 eligible participants will be randomly allocated into verum acupuncture group or sham acupuncture group, in a 1:1 ratio. The verum acupuncture group will receive 16 sessions of manual acupuncture treatments over an eight-week period, while the sham acupuncture group will receive sham acupuncture treatments with non-penetrating needling. Health education will be provided to participants in the two groups. The primary outcomes will be the changes in the mean levels of serum uric acid 8 weeks after randomization. The secondary outcomes will be the changes in the mean levels of serum uric acid 4, 12, 16, and 20 weeks after randomization. Other secondary outcomes included effective rates, the proportion of patients with acute gouty arthritis, changes in body weight and BMI, safety evaluation and deqi evaluation. The central randomization and data collection will be conducted by an electronic data management system.
