Hyperuricemia and gout.
Due to high uric acid clearance, which occurs prior to puberty, hyperuricosuria rather than hyperuricemia may be the only clue to diagnosis of purine overproduction in children who have enzymatic defects or who develop the condition in the course of treatment of malignancies. The probable inclusion of hyperuricemia as a part of syndrome X associated with insulin resistance may help in understanding its clinical associations, including coronary artery disease. Gout, hypertension, and lead often go together; thus, perhaps we should check for lead toxicity routinely in this setting. Asymptomatic joints of patients with gout contain monosodium urate crystals, and research on the factors that determine the occurrence of clinical inflammation in this setting continues as an area of current interest. Coating of the crystals by different proteins may modify their inflammatory potential and may be an important modulating mechanism.
