Uric Acid in Primary Hyperparathyroidism: Marker, Consequence, or Bystander?

Area of Science:

• Endocrinology
• Nephrology
• Metabolic Research

Background:

• Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular risk.
• Uric acid (UA) is a metabolite implicated in cardiovascular disease and chronic kidney disease (CKD).
• The relationship between PHPT and UA requires further elucidation.

Purpose of the Study:

• To review the pathophysiological mechanisms linking PHPT and UA.
• To discuss the clinical implications of the PHPT-UA association.
• To explore the role of UA in PHPT-related complications.

Main Methods:

• Comprehensive literature review.
• Focus on physiological and clinical aspects of the PHPT-UA relationship.
• Analysis of existing evidence on underlying mechanisms.

Main Results:

• Evidence supports an association between PHPT and elevated UA levels.
• Potential mechanisms include tubular/intestinal transporters (e.g., ABCG2) and hypercalcemia.
• Inflammatory processes may also mediate the relationship.

Conclusions:

• PHPT and UA share linked pathophysiological mechanisms in mineral and purine metabolism.
• The active role of UA in PHPT complications remains unclear; it may be a marker of metabolic dysfunction.
• Measuring UA in PHPT patients, especially those with risk factors, is recommended for preventing complications.
