[Hypocholesterolemia and other lipoprotein disorders in myelofibrosis].

In the recent years more and more data suggest a significant relationship between malignant diseases and cholesterol, respectively lipoprotein metabolism. It is a significant decrease of cholesterol in primary myelofibrosis (agnogenic myeloid metaplasia) and in secondary myelofibrosis. Similarly, the HDL and LDL cholesterol levels are also decreased in these diseases. On the contrary, the triglyceride level is significantly higher in these groups, 41 patients with agnogenic myeloid metaplasia and 16 patients with myelofibrosis following polycythaemia vera were examined. Decrease of serum cholesterol level was significant: 3.7 and 3.3 mmol/l and 5.2 mmol/l in 76 healthy controls, as the mean values.
