In the diabetic patient, hyperkalemia and hyperchloremic metabolic acidosis has been attributed to one or more of the following factors associated with diabetic nephropathy: hypoaldosteronism, altered potassium homeostasis, or a distal tubular (DT) defect in hydrogen ion secretion. To evaluate maximal in vivo DT acidification in streptozotocin (STZ) diabetes, unidirectional bicarbonate reabsorption (JHCO3) was measured in DTs after acid loading and in surviving DT after 2/3 nephrectomy (Nx).
