Vasodilation in Patients With Fabry's Disease

Completed

Conditions studied: Cerebrovascular Accident, Fabry Disease, Healthy

In brief

Fabry's disease a genetic disorder (X-linked recessive) due to the absence of the enzyme alpha-galactosidase A. The disease is characterized by abnormal collections of glycolipids in cells (histiocytes) within blood vessel walls, tumors on the thighs, buttocks, and genitalia, decreased sweating, tingling sensations in the extremities, and cataracts. Patients with Fabry 's disease die from complications of the kidney, heart, or brain. The objective of this study is to test the belief that patients with Fabry's disease have a problem with blood vessels becoming larger. The walls of blood vessels contain muscles that when they relax the vessel becomes larger. This process is referred to as vasodilation. It is controlled by a substance released by cells in blood vessels called EDRF (endothelium-derived relaxing factor). Several drugs can affect vasodilation. Researchers believe some drugs may work by blocking the affect of EDRF. Researchers would like to test the effects of these drugs on the blood vessels of normal volunteers and patients with Fabry's disease.
