Abstract:
Sodium pentosan polysulphate (SPP) is reported to influence lipid metabolism, and since a relationship between lipids and stone disorder has been recognised, it was thought worthwhile to study the role of SPP in relation to serum lipids and lipoproteins in experimental calcium oxalate urolithiasis. Serum cholesterol, triglycerides and phospholipids were significantly increased in the glycollate treated group while free fatty acids showed only a mild increase. SPP treatment decreased the cholesterol and triglyceride levels in both controls and stone formers. In contrast, phospholipid and free fatty acid levels were increased in the two groups. In the calculogenic rats, the LDL/HDL cholesterol ratio showed no change, whereas with SPP administration there was a decrease in the treated groups. The observations are suggestive, that SPP treatment may prove beneficial in decreasing the blood lipid levels.
