title: Decreased activities of lipoprotein lipase and hepatic triglyceride lipase in patients with gout.
abstract: Postheparin plasma lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) activities were measured in 30 male primary gout patients as well as in control subjects. The activities of these lipolytic enzymes were significantly decreased in the patients as compared with the controls (gout v control; LPL, 5.4 +/- 0.4 v 7.9 +/- 0.9 U; HTGL, 14.6 +/- 2.0 v 17.9 +/- 3.4 U) when matched with serum triglyceride concentration. Further, LPL activity was negatively correlated with serum- and very-low-density lipoprotein (VLDL)-triglyceride in gout patients, while that of HTGL was negatively correlated with low-density lipoprotein (LDL)-triglyceride in both gout patients and control subjects. These results suggest that decreased activities of LPL and HTGL may contribute, in part, to the increased concentrations of serum-, VLDL-, and LDL-triglyceride seen in gout patients, leading to a higher risk for coronary atherosclerotic diseases in gout.
