Postprandial triglyceride levels in familial combined hyperlipidemia. The role of apolipoprotein E and lipoprotein lipase polymorphisms.

The effect of apolipoprotein E genotype and polymorphisms of lipoprotein lipase gene on plasma postprandial triglyceride levels in familial combined hyperlipidemic subjects and their relatives have not been sufficiently studied. This study included sixteen familial combined hyperlipidemic parents (G1): age: 52 +/- 9 years with total-cholesterol: 7.2 +/- 1.

High normal serum levels of C3 and C1 inhibitor, two acute-phase proteins belonging to the complement system, occur more frequently in patients with Crohn's disease than ulcerative colitis.

Few data are available on measurements of serum concentrations of complement proteins in inflammatory bowel disease (IBD). Therefore we measured serum levels of C3, C4, and C1-esterase inhibitor (C1-INH) as well as C-reactive protein (CRP) in 167 patients with Crohn's disease (CD) and 111 patients with ulcerative colitis (UC). Median serum concentrations of C3 and C1-INH were significantly higher in CD than in UC.
