Data Collection in Women With Fabry Disease

2014-08-27 03:56:21 | BioPortfolio

Summary

This protocol will collect information needed to design a clinical study for the symptoms and problems of women with Fabry disease, an inherited metabolic disorder. In this disease, an enzyme called a-galactosidase A, which normally breaks down fatty substances called glycolipids, does not function properly. The resulting accumulation of glycolipids in various tissues causes arm and leg pain, skin lesions, and problems with the kidneys, heart, nerves, and blood vessels. This protocol does not involve any experimental drug treatments, but participants may be offered enrollment in future studies and registries.

Women 18 years of age and older with Fabry disease who have not had enzyme replacement therapy may participate in this study. Pregnant women are eligible, but may be excluded from certain procedures, such as magnetic resonance imaging (MRI).

Participants will have the following tests and procedures over a 3-day period:

- Personal and family medical history

- Physical, neurological, and eye examinations

- Blood and urine tests

- Electrocardiogram (ECG) to measure electrical activity of the heart

- Echocardiogram (ultrasound) to examine the heart muscles and pumping action

- Magnetic resonance imaging (MRI) to examine the brain. This test uses a magnetic field and radio waves to produce images of the brain. The patient lies in a narrow cylinder (the MRI scanner) during the imaging and may talk with staff at any time during the procedure.

- Magnetic resonance angiogram (MRA) to examine the blood vessels in the head and neck. This procedure is similar to MRI.

- Genotyping to confirm the diagnosis of Fabry disease. DNA from a blood sample will be examined for the gene associated with Fabry disease.

- Skin punch biopsy for microscopic examination of tissue. A piece of skin tissue about 1/8-inch thick is removed with a cookie cutter-like instrument.

Participants will also complete two questionnaires regarding pain and quality of life. They will be asked to stop taking pain medications for 7 days before completing the pain questionnaire, but may resume medications before 7 days if the pain is too intense. The questionnaire will be completed by telephone interview.

Patients will also be asked to keep a diary of pain medications taken for 7 days while on the study.

Description

This is a study to collect normative data in female patients with Fabry disease. After signing informed consent, patients will complete various study evaluations. Serious adverse events will be monitored throughout the patients study participation (approximately 7 days).

Medical and Biotech [MESH] Definitions

An X-linked inherited metabolic disease caused by a deficiency of lysosomal ALPHA-GALACTOSIDASE A. It is characterized by intralysosomal accumulation of globotriaosylceramide and other GLYCOSPHINGOLIPIDS in blood vessels throughout the body leading to multi-system complications including renal, cardiac, cerebrovascular, and skin disorders.

Members of the class of neutral glycosphingolipids. They are the basic units of SPHINGOLIPIDS. They are sphingoids attached via their amino groups to a long chain fatty acyl group. They abnormally accumulate in FABRY DISEASE.

Glycosphingolipids which contain as their polar head group a trisaccharide (galactose-galactose-glucose) moiety bound in glycosidic linkage to the hydroxyl group of ceramide. Their accumulation in tissue, due to a defect in ceramide trihexosidase, is the cause of angiokeratoma corporis diffusum (FABRY DISEASE).

Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.

Analyses for a specific enzyme activity, or of the level of a specific enzyme that is used to assess health and disease risk, for early detection of disease or disease prediction, diagnosis, and change in disease status.
