La description
Inclusion Criteria:
- Age 18-60 years.
- Men with serum uric acid levels > 420 μmol/L on 2 separate occasions (not on the same day), women with serum uric acid levels > 360 μmol/L on 2 separate occasions (not on the same day).
- Participants must sign an informed consent form and be able to cooperate with sample collection.
Exclusion Criteria:
- A history of or current presence of a clearly defined organic intestinal disease, such as intestinal malignant tumor, inflammatory bowel disease, intestinal obstruction, or intestinal polyp.
- Concurrent severe systemic diseases, including severe cardiovascular or cerebrovascular disease (eg., myocardial infarction within the past 6 months, NYHA Class III-IV heart failure, or uncontrolled hypertension), significant liver function abnormalities (ALT or AST > 2 times the upper limit of normal), moderate-to-severe renal insufficiency (eGFR < 45 mL/min/1.73 m²) or uncontrolled diabetes (HbA1c ≥ 9%).
- Use of antibiotic, probiotic preparation, or other drugs that may significantly alter the gut microbiota within 4 weeks prior to enrollment, or those requiring continued use of such drugs during the study.
- Women who are pregnant or lactating, or who plan to become pregnant during the study.
- Participants with severe tophus or gouty nephropathy.
- Participants who have participated in another clinical trial within 3 months prior to enrollment.
- Participants with other health problems that render them unsuitable for enrollment.

Expérimental: Probiotic-uricase complex plus conventional management
Participants in the intervention group will receive the probiotic-uricase complex preparation during a 2-week treatment period in addition to conventional management.
A 2-week follow-up period will follow treatment, with assessments at Weeks 0, 1, 2, 3, and 4. Participants maintain their usual diet and avoid additional probiotics or antibiotics.
Adherence is monitored through capsule counts and diaries.
Clinical and biological evaluations will include blood, urine, and fecal sample collection for assessment of uric acid metabolism, related metabolites, gut microbiota composition, and safety parameters.
Serum uric acid will be monitored longitudinally to evaluate changes from baseline during treatment and post-treatment follow-up.
|
Participants receive the probiotic-uricase complex preparation capsule orally.
Each participant takes it for 2 weeks.
Adherence is monitored through capsule counts and diaries.
Clinical and biological evaluations will include blood, urine, and fecal sample collection for assessment of uric acid metabolism, related metabolites, gut microbiota composition, and safety parameters.
Serum uric acid will be monitored longitudinally to evaluate changes from baseline during treatment and post-treatment follow-up.
|
|
Aucune intervention: Conventional management alone
Participants will receive conventional management alone without the probiotic-uricase complex preparation.
Assessments will be conducted at Weeks 0, 1, 2, 3, and 4. Participants maintain their usual diet and avoid additional probiotics or antibiotics.
Clinical and biological evaluations will include blood, urine, and fecal sample collection for assessment of uric acid metabolism, related metabolites, gut microbiota composition, and safety parameters.
Serum uric acid will be monitored longitudinally to evaluate changes from baseline during treatment and post-treatment follow-up.
