[Association Between Serum Uric Acid and Acute Cerebral Infarction: a Case Control Study]

Area of Science:

• Neurology
• Biochemistry
• Epidemiology

Background:

• Serum uric acid is an antioxidant, and its role in cerebrovascular diseases is debated.
• Previous studies have yielded conflicting results regarding the association between uric acid levels and stroke.
• Understanding this relationship is crucial for identifying potential biomarkers and therapeutic targets for acute cerebral infarction.

Purpose of the Study:

• To investigate the association between serum uric acid levels and the occurrence of acute cerebral infarction.
• To determine if serum uric acid can serve as a predictive marker for acute cerebral infarction.

Main Methods:

• A case-control study involving 700 patients with acute cerebral infarction and 700 healthy controls.
• Serum levels of uric acid, triglyceride, cholesterol, blood glucose, urea, and creatinine were measured.
• A logistic regression model was employed to analyze the association, controlling for confounding factors.

Main Results:

• Patients with acute cerebral infarction exhibited lower serum uric acid levels compared to healthy controls (P < 0.05).
• Logistic regression analysis indicated a weak association between decreased serum uric acid levels and acute cerebral infarction (OR: 0.998, 95% CI: 0.996-1.000, P < 0.05) after adjusting for covariates.
• The findings suggest that lower uric acid levels are not a strong independent risk factor for acute cerebral infarction.

Conclusions:

• The study did not confirm a significant association between serum uric acid levels and acute cerebral infarction.
• The observed association was minimal and requires further investigation with larger, diverse cohorts.
• Serum uric acid's role as a biomarker for acute cerebral infarction remains uncertain.
