Flashcards in 50. Renal osteodystrophy Deck (6):
Renal osteodystrophy ?
hypocalcemia, hyperphosphatemia and failure of vit D hydroxylation associated with chronic renla disease --> secondary hyperparathyroidism
ALSO hyperphosphatemia decreases serum Ca2+ by causing tissue calcification wheres low Vit D --> low interstinal Ca2+ absorption
Renal osteodystrophy causes ...(on bones)
subperiosteal thinning of bones
• Renal osteodystrophy arises as a result of the failure of what kidney function?
Production of active vitamin D, leading to hypocalcemia and a secondary increase in parathyroid hormone, resulting in bone loss
• A renal failure patient's bone scan shows subperiosteal bone thinning; labs: low vitamin D, hypocalcemia, and hyperphosphatemia. Diagnosis?
Renal osteodystrophy (secondary hyperparathyroidism)
• Renal osteodystrophy arises as a result of a failure of which step in vitamin D processing?
Vitamin D hydroxylation
