Participant gender:

Summary
Patients with Type I Hyperlipoproteinemia (T1HLP) have a rare form of hypertriglyceridemia marked by significant chylomicronemia and recurrent episodes of acute pancreatitis. T1HLP is caused by a deficiency of lipoprotein lipase or one of its cofactors. Many patients are a challenge to treat, as the only effective therapy available is an extremely low fat diet. This diet is exceedingly difficult to follow, and despite adherence, many patients still have chylomicronemia and develop acute pancreatitis. Specific Aim: To determine the efficacy of a gastric and pancreatic lipase inhibitor, Orlistat, in reducing serum triglyceride levels in patients with T1HLP.
