Interrelations of PTH, cAMP, creatinine and uric acid in nephrectomized patients under DNA or PTH application.
Patients with reduced renal mass (i.e., nephrectomized) and slightly decreased renal clearance (70-80%) have been treated by 4 g DNA to study uricosuria. Prompt or prolonged renal excretion of uric acid and creatinine have been observed with indirect effects on parathyroid secretion. Urinary cAMP, however, failed to correlate to the change of parathyroid function. Reversely, PTH injection significantly increases uricosuria suggesting interrelated secretion of uric acid and cAMP of the proximal tubules. In some respects this model can be used to investigate increased DNA metabolism and parathyroid function.
