研究目的: |
本研究拟通过双盲随机对照试验,在高尿酸人群(serum uric acid , SUA ≥ 480 μmol/L)中,评价乳酸片球菌食品补充剂对血尿酸等指标的改善作用,并探究肠道菌群的潜在作用,为高尿酸血症患者降低尿酸的营养干预提供依据。 |

|
Objectives of Study: |
This study aims to evaluate the effects of Pediococcus acidilactici supplementation on serum uric acid (SUA) levels and other related indicators in individuals with hyperuricemia (SUA ≥ 480 μmol/L) through a randomized, double-blind, controlled trial. Furthermore, the study will explore the potential role of the gut microbiota to provide a scientific basis for nutritional interventions in uric acid management for patients with hyperuricemia. |

|
Description for medicine or protocol of treatment in detail: |
The study consists of a 1-week run-in period (including informed consent, baseline characteristic and clinical data collection) followed by an 8-week intervention period. Eligible volunteers who meet the inclusion/exclusion criteria and sign the informed consent will be randomized into the live probiotic group (active Pediococcus acidilactici BH0068 with maltodextrin, n=56), the inactivated probiotic group (inactivated Pediococcus acidilactici BH0068 with maltodextrin, n=56), or the control group (maltodextrin only, n=56). The intervention materials will be distributed at Week 0 and Week 4. Participants are required to undergo physical examinations and biological sample collection (blood and urine samples) at Week 0, 4, and 8, with additional fecal sample collection at Week 0 and 8. Relevant questionnaires will also be completed during these visits. |

盲法: |
本研究采用双盲设计,汤臣倍健公司加工形状、颜色、气味和包装均一致的补充剂和安慰剂。每种补充剂外包装上采用简单随机化法标识区分组别及生产厂家信息、保质期、生产日期等基本信息。补充剂和安慰剂按每人4周所需的总量进行包装(适当多3-5天的量)。 |
|
Blinding: |
This study employs a double-blind design. By-Health Co., Ltd. will provide the supplements and placebos, which are identical in appearance, color, odor, and packaging.
