Introduction
Causes of Elevated Uric Acid Levels:
Dietary Factors: Consumption of high-purine foods—such as red meat, seafood, animal offal, and concentrated meat broths—as well as alcohol intake (especially beer) and intense physical exercise can all increase serum uric acid levels.
Medical Conditions: Hyperuricemia is frequently associated with hypertension, hyperlipidemia, atherosclerosis, coronary artery disease, and diabetes mellitus.
Medications: Prolonged use of certain drugs may also elevate serum uric acid levels.
Elevated uric acid levels result from purine metabolism disorders—either excessive endogenous uric acid production or reduced renal excretion—and may be primary (idiopathic) or secondary to certain underlying diseases. As prevalence increases with age, what factors contribute to hyperuricemia?
Causes of Elevated Uric Acid
Causes of hyperuricemia include: Dietary factors: Consumption of high-purine foods—such as red meat, seafood, organ meats, and concentrated meat broths—as well as alcohol intake (especially beer) and intense physical exercise can all elevate serum uric acid levels. Medical conditions: Hyperuricemia frequently coexists with hypertension, hyperlipidemia, atherosclerosis, coronary artery disease, and diabetes mellitus. Medications: Prolonged use of certain drugs may impair uric acid excretion and thereby increase serum uric acid levels. These include low-dose aspirin, loop diuretics, thiazide diuretics, insulin, glucocorticoids, calcium channel blockers, and beta-blockers.
Pharmacologic management of hyperuricemia aims either to inhibit uric acid production or enhance its excretion. Xanthine oxidase inhibitors (e.g., allopurinol) are commonly used; newer agents such as febuxostat offer rapid uric acid-lowering effects and prompt dissolution of monosodium urate crystals. Benzbromarone, a uricosuric agent, also effectively lowers serum uric acid and promotes dissolution of uric acid stones and crystals—but its use must be individualized based on the patient’s uric acid excretion status. In cases of overexcretion, uric acid–lowering agents that suppress production (e.g., xanthine oxidase inhibitors) should be prioritized. Sodium bicarbonate serves as an adjunctive therapy by alkalinizing the urine, thereby enhancing solubility and urinary excretion of uric acid salts and preventing crystal formation and associated renal damage.
During treatment, patients should maintain adequate hydration to facilitate smooth renal excretion of uric acid salts and minimize crystal formation. We hope this article has been helpful!
