[Alterations in lipidic metabolism in hemodialysis patients].

Background: Chronic kidney failure is associated with dyslipidemia and accelerated atherosclerosis.

Aim: To study lipidic metabolism alterations in patients with chronic kidney failure on hemodialysis.

Methods: The study interested 45 hemodialysis patients with a mean age of 49.04 ±15.92 years old and 45 healthy controls. A blood sample was collected from each patient and control to measure total cholesterol, triglycerides, HDL- cholesterol, LDL-cholesterol, apolipoproteins AI and B100, lipoprotein (a) and C Reactive Protein.

Results: A significant increase of serum triglycerides (p= 0.002), lipoprotein (a) (p = 0.001) and C Reactive Protein (p = 0.008) was observed in patients when compared with healthy controls. A significant decrease of serum total cholesterol (p=0.01), HDLcholesterol (p<0.001), LDL-cholesterol (p=0.005) and apolipoprotein AI (p<0.001) was also observed in patients.

Conclusion: Disorders of lipidic metabolism are frequent in hemodialysis patients. These alterations can lead to cardiovascular disease in uremic patients.
