Current updates and future perspectives in uric acid research, 2024.

Area of Science:

• Cardiovascular Science
• Nephrology
• Metabolic Disorders

Background:

• Uric acid, the end product of purine metabolism, is increasingly linked to hypertension and cardiovascular disease (CVD).
• Previous reviews have established connections, but recent advancements necessitate an updated perspective.

Purpose of the Study:

• To provide an updated summary of recent findings on hyperuricemia and its associations.
• To explore the relationship between hyperuricemia and various conditions including hypertension, preeclampsia, arteriosclerosis, kidney disease, and sleep-disordered breathing.

Main Methods:

• Literature review of studies published in the past two years.
• Synthesis of recent clinical and basic science research on hyperuricemia and purine metabolism.

Main Results:

• Hyperuricemia is associated with hypertension, preeclampsia, arteriosclerosis, kidney disease, and sleep-disordered breathing.
• Factors influencing hyperuricemia include genetics, diet (high-purine foods, alcohol, fructose), and reduced uric acid excretion or increased production.
• Proposed mechanisms linking hyperuricemia to CVD involve inflammasome activation and oxidative stress, though causality is debated.

Conclusions:

• Hyperuricemia is linked to a spectrum of cardiovascular and renal conditions.
• Further research is needed to elucidate the causal role of hyperuricemia in CVD and inform therapeutic strategies.
• Understanding purine metabolism is crucial for managing associated health risks.
