Effect of Fenofibrate on Serum and Tissue Sialic Acid Levels in Short-term Experimental Hypercholesterolemia

Abstract

In recent years, sialic acid is considered to be a possible marker for cardiovascular diseases. The aim of this study was to investigate the effect of two different treatment periods of fenofibrate (CAS 49562-28-9) on serum, heart and liver sialic acid levels in experimental hypercholesterolemia. Serum, heart and liver total sialic acid levels were determined by Warren's thiobarbituric acid (TBA) method and serum lipid levels by commercial kits at the end of the fenofibrate treatment for 3 and 6 weeks. Fenofibrate treatment reduced serum total sialic acid levels significantly in the control and hypercholesterolemic groups at the end of the 3rd week and only in the control group at the end of the 6th week. Serum sialic acid levels of fenofibrate-treated hypercholesterolemic rats in the 6-week period were significantly higher than those in the 3-week period. Neither the hypercholesterolemic diet nor fenofibrate had any significant effect on heart and liver sialic acid levels. In conclusion, decreased serum sialic acid levels in control and hypercholesterolemic groups by fenofibrate short-term treatment may contribute to the decreased risk of cardiovascular diseases that accompanies the hypercholesterolemic complications. The decreased serum sialic acid levels further indicate the clinical efficacy of fenofibrate as an anti-inflammatory agent.

Clinical evaluation of total and lipid bound sialic acid levels in oral precancer and oral cancer

“…Oral antidiabetic drugs, for example, metformin and rosiglitazone raise the serum sialic acid levels, while fenofibrate (reduce cholesterol levels in patients at risk of cardiovascular disease), anti-inflammatory agents such as mefanamic acid and chemotherapeutic agents lower the serum sialic acid content. [7,22,23] None of the patients in our study were either on any drugs or were suffering from any of the above-mentioned diseases that could alter the serum sialic acid level.…”
