Exploring the association between bipolar disorder and uric acid: A mediation analysis

Area of Science:

• Neuroscience
• Metabolic Disorders

Background:

• Emerging evidence suggests a link between bipolar disorder and dysfunction of the purinergic system.
• Uric acid, a product of purine metabolism, is a potential indicator of purinergic system activity.

Purpose of the Study:

• To investigate the association between bipolar disorder and serum uric acid levels.
• To determine if metabolic syndrome and related factors mediate this association.

Main Methods:

• Cross-sectional study including patients with bipolar disorder, other severe mental disorders, and healthy controls.
• Linear regression analyses and mediation tests were used to explore associations and mediating effects.

Main Results:

• Bipolar disorder was significantly associated with elevated uric acid levels.
• Male gender, metabolic syndrome, abdominal circumference, and triglycerides also affected uric acid levels.
• Metabolic abnormalities partially mediated the relationship between bipolar disorder and uric acid.

Conclusions:

• A direct association exists between bipolar disorder and uric acid levels, partially influenced by metabolic factors.
• Findings support the hypothesis of purinergic system dysfunction in bipolar disorder.
• Purinergic modulators that lower uric acid may offer therapeutic potential for bipolar disorder.
