Abnormalities of serum apo A1 containing lipoprotein particles in patients with primary biliary cirrhosis

Patients with primary biliary cirrhosis (PBC) do not appear to have an increased risk of cardiovascular disease despite elevations in serum cholesterol. Recent evidence has pointed to LpA1 (an apo A1 containing particle which contains apo A1 but not apo A2) in protecting against atherosclerosis. The...

Zusammenfassung:Patients with primary biliary cirrhosis (PBC) do not appear to have an increased risk of cardiovascular disease despite elevations in serum cholesterol. Recent evidence has pointed to LpA1 (an apo A1 containing particle which contains apo A1 but not apo A2) in protecting against atherosclerosis. The aim of this study was to investigate apo A1 containing particles in the serum of patients with PBC. Lipids and apolipoproteins were measured in 31 patients with PBC (30 females) and 27 control subjects (26 females). Patients were divided into 3 groups: group 1 with bilirubin 18 μmol/l ( n=11); and group 3 with end stage liver disease (ESLD, n=3). As expected group 1 and 2 patients had higher total cholesterol, HDL cholesterol and phospholipids than control subjects. Apo B and apo A1 concentrations were similar to control subjects. However, LpA1 was greatly increased: 0.96 g/l (0.60–1.50), median (range) in group 1 and 1.09 g/l (0.75–1.33) in group 2 versus 0.62 g/l (0.45–0.93) for controls both P
