Hypercalcaemia Secondary to Hypervitaminosis A in a Patient with Chronic Renal Failure

Sagliker Syndrome in a Patient with Secondary Hyperparathyroidism and Chronic Renal Insufficiency: A Case Report

Sagliker syndrome is a rare form of renal osteodystrophy resulted from untreated secondary hyperparathyroidism. It is described by severe skeletal deformities, high level of PTH in patients with chronic renal failure, and deformed face. This paper reports a 44-year-old male patient with the mentioned characteristics. In addition to the unique clinical features, high levels of ALP and PTH hormon...

Hypervitaminosis A accompanying advanced chronic renal failure.

How to evaluate hypercalcaemia in the patient with chronic renal failure.

In the normal human subject, the plasma concentration of ionized calcium is tightly regulated within an extremely narrow range [1]. The kidney plays an important role in normal calcium homeostasis. It regulates the excretion of calcium and phosphorus and is the site of production of 1,25(OH)2D3. Furthermore, it is one of the effector organs for calcium-regulating hormones, 1,25(OH)2D3 and PTH. ...

Vitamin A toxicity and hypercalcaemia in chronic renal failure.

Serum vitamin A concentrations were measured in 38 patients undergoing haemodialysis, 24 of whom were taking multivitamin preparations containing vitamin A. Vitamin A concentrations were significantly higher in patients undergoing haemodialysis than in 28 normal controls (p less than 0.001). Patients taking vitamin A supplements had significantly higher vitamin A concentrations than those not t...
