Abstract

Hypercholesterolemia is a common disorder in adult population, but total cholesterol concentrations beyond 1000 mg/dl occur rarely, and are found in patients with homozygous familial hypercholesterolemia and familial lecithin-cholesterol acyltransferase deficiency, in chronic graft-versus-host disease of the liver, after intravenous infusion of fat emulsion (intralipid), in newborn infants with immature liver function, and in obstructive biliary cholestasis. Cholestasis induces a dramatic increase in plasma cholesterol and the appearance of an abnormal lipoprotein, lipoprotein X (LpX), in the plasma. We report a case of severe hypercholesterolemia mediated by LpX in a patient transplanted for primary biliary cirrhosis (PBC), who was qualified for liver re-transplantation (re-LTx) due to chronic cholestasis. Four months after re-LTx, the cholesterol concentration was normal. The problems in diagnosis and treatment are discussed.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
