2014-08-27 03:58:13 | BioPortfolio

Summary

OBJECTIVES: I. Evaluate migraine prophylaxis with soy protein isolate in patients with hereditary hemorrhagic telangiectasia.

II. Assess whether soy protein isolate reduces the frequency and severity of epistaxis and gastrointestinal bleeding in these patients.

Description

PROTOCOL OUTLINE: This is a randomized study. One group of patients is treated with soy protein isolate for 12 weeks. The control group receives a placebo for 12 weeks.

Patients cross to the alternate group following a 4-week washout.

Laryngeal hereditary hemorrhagic telangiectasia.

Medical and Biotech [MESH] Definitions

An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.

A membrane glycoprotein and ANGIOGENESIS FACTOR that is expressed by cells of the VASCULAR ENDOTHELIUM; VASCULAR SMOOTH MUSCLE; and MONOCYTES. It functions as a co-receptor for TRANSFORMING GROWTH FACTOR BETA and modulates CELL ADHESION. Mutations in the endoglin gene are associated with cases of HEREDITARY HEMORRHAGIC TELANGIECTASIA.

Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.

A group of viral diseases of diverse etiology but having many similar clinical characteristics; increased capillary permeability, leukopenia, and thrombocytopenia are common to all. Hemorrhagic fevers are characterized by sudden onset, fever, headache, generalized myalgia, backache, conjunctivitis, and severe prostration, followed by various hemorrhagic symptoms. Hemorrhagic fever with kidney involvement is HEMORRHAGIC FEVER WITH RENAL SYNDROME.

A Fanconi anemia complementation group protein that undergoes mono-ubiquitination by FANCL PROTEIN in response to DNA DAMAGE. Also, in response to IONIZING RADIATION it can undergo PHOSPHORYLATION by ataxia telangiectasia mutated protein. Modified FANCD2 interacts with BRCA2 PROTEIN in a stable complex with CHROMATIN, and it is involved in DNA REPAIR by homologous RECOMBINATION.
