Serum lipoprotein concentrations in cystic fibrosis.

Two major classes of lipoproteins, low density and high density, are decreased 
in the serum of patients with cystic fibrosis; major apoproteins are 
also decreased. Since essential fatty acids and certain fat-soluble vitamins depend 
on lipoproteins for transport in the serum, knowledge of lipoprotein levels 
in cystic fibrosis patients could prove valuable in understanding (i) the 
basis for the abnormally low serum levels of these fatty acids 
and vitamins and (ii) the effects of therapies involving these molecules.
