Serum vitamin A, retinyl esters and vitamin E in nephrotic syndrome.

Serum vitamin A, retinyl esters and vitamin E were increased in a group of 33 patients with chronic glomerulonephritis and nephrotic syndrome without reduction of mean glomerular filtration rate. Despite hypoproteinaemia and reduced values of serum proteins with a different molecular weight, increased values of vitamin A protein carriers were found. Serum total cholesterol, LDL cholesterol, triglyceride, prebeta und beta lipoproteins were increased, HDL cholesterol was within the reference range.
