Hyperkalemia and acidosis in lead nephropathy.
Defective potassium excretion with clinical acidosis, associated with fixed moderate sodium wasting, has been found to be a common abnormality in lead nephropathy. Lead poisoning has been shown by others to be associated with depression of the renin-aldosterone system and of sodium and potassium activated adenosinetriphosphatase (ATPase). Since these hormonal defects may contribute to the hyperkalemia and are reversible, lead poisoning should be treated aggressively. Management also requires proper regulation of dietary sodium, correction of acidosis, limitation of dietary potassium, and minimal use of antihypertensive agents, as well as the administration of allopurinal for urate control.
