Renal tubular dysfunction in transplanted kidneys. 1979

N D Vaziri, and R E Nellans, and R M Brueggemann, and C H Barton, and D C Martin

We studied 15 renal transplant recipients for evidence of tubular dysfunction. Eight patients were hypophosphatemic, and two had systemic acidosis with a urinary acidification defect. Mild aminoaciduria and bicarbonaturia were present in four and 14 patients, respectively. Elevated parathyroid hormone level was found in only one patient. Tubular reabsorption of phosphorus was depressed in all eight hypophosphatemic patients, while no such abnormalities were observed in 14 control subjects. Defective tubular reabsorption of phosphorus was the most striking abnormality. None of the parameters studied, including immunosuppressant therapy, parathyroid hormone levels, creatinine clearance, or acid-base balance, clearly account for the pathogenesis of this abnormality.

UI MeSH Term Description Entries
D007674 Kidney Diseases Pathological processes of the KIDNEY or its component tissues. Disease, Kidney,Diseases, Kidney,Kidney Disease
D007684 Kidney Tubules Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER. Kidney Tubule,Tubule, Kidney,Tubules, Kidney
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.
