title: The effects of vitamin A toxicity on calcium and lipid metabolism in chronic renal failure.
abstract: Serum vitamin A levels were high in haemodialysis patients, and were found to correlate with plasma calcium, triglyceride, cholesterol and insulin levels. Vitamin A containing multivitamin supplements were found to contribute to increased serum vitamin A levels, and their withdrawal in seven patients caused a significant decrease in serum vitamin A and calcium levels, with no effect on lipid levels. Vitamin A containing preparations should therefore be prescribed with caution in these patients.
