Analysis of the Nervous System in Patients With Fabry's Disease

Completed
Conditions
Fabry's Disease
Registration Number
NCT00001491
Lead Sponsor
National Institute of Neurological Disorders and Stroke (NINDS)
Brief Summary

Fabry's disease a genetic disorder (X-linked recessive) due to the absence of the enzyme ceramidetrihexosidase. 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 purpose of this study is to measure levels of a protein marker (PGP 9.5) in the skin, blood, and fluid surrounding the brain and spinal cord (CSF) in patients with Fabry's disease. In addition the study will attempt to determine if levels of the protein are directly related to the severity of disease in the nervous system.

PGP 9.5 protein levels will be measured in normal volunteers and patients with other diseases of the nervous system then compared to the levels recorded in patients with Fabry's disease.

This research study is designed to improve the understanding of Fabry's disease. Patients participating in it will not directly benefit from it. However, knowledge gained as a result of this study may contribute to the development of effective therapies for Fabry's disease.

Detailed Description

OBJECTIVE: The purpose of this protocol is to study the natural history of Fabry disease in the different organ systems, understand its pathogenesis, and develop adequate clinical outcome measures for therapy trials. Development of sensitive outcome measures is a prerequisite of enzyme or gene replacement trials in patients with Fabry's disease. STUDY POPULATION: Patients with Fabry disease of all ages. The patients are not foregoing available treatment to participate in this protocol. Experimental treatment is not part of this study. STUDY DESIGN: Patients will typically be seen once a year at NIH. Patients will have comprehensive testing in order to evaluate the state of their health as affected by the Fabry disease. OUTCOME MEASURES: All potential clinically relevant areas will be evaluated comprehensively with a particular emphasis on the vasculopathy and the peripheral neuropathy of Fabry disease.
