Uric Acid Metabolic Disorders in Pituitary-Target Gland Axis

: Uric acid (UA) is the end product of purine metabolism in the human, and the imbalance between production and excretion results in the disturbance of serum uric acid (SUA). There is evidence suggesting that pituitary-target gland hormones can affect UA metabolism through regulating the activity of xanthine oxidase and UA transporters. Related endocrine diseases including thyroid dysfunction, polycystic ovary syndrome, acromegaly and Cushing's syndrome are often accompanied by elevated UA levels. In addition to the direct influence of abnormal hormones, obesity and insulin resistant play a pivotal role. Diabetes insipidus and the syndrome of inappropriate antidiuretic hormone secretion also present with abnormal SUA levels due to the action of antidiuretic hormone. However, certain evidence within the population is disputed. This review summarized the effects of pituitary-target gland hormones on UA metabolism, and preliminarily described the related mechanisms, offering a theoretical foundation for assessing SUA in endocrine disorders as well as guiding its management.
