The article by Glueck et at.1 dealing with the effect of cholestyramine and of diet therapy on the level of plasma vitamin A in familial type II hyperlipoproteinemia patients is somewhat disturbing because of the reported high levels of vitamin A found in the plasma of both normal and type II children.
In Table I of the article the vitamin A levels are reported in µmol/liter. Converting these values to the more familiar notation, µg/dl, one obtains the results shown in Table I.
