- To establish and maintain a database of clinical material (i.e., blood, urine, and tissue) and information on patients with primary systemic amyloidosis.
OUTLINE: Blood, urine, tissue, and bone marrow samples are collected during standard laboratory evaluations to maintain a repository of biospecimens in the Gerry Amyloid Research Laboratory, to permit the correlation of clinical results with measured biological events, and for future research studies. Bone marrow RNA samples are examined for immunoglobulin light-chain gene sequences and amino acids by PCR and positional cloning. Blood serum and urine samples are evaluated for amyloid protein stability by high-resolution calorimetry, isothermal-titration calorimetry, and far- and near-UV circular dichroism and fluorescence spectroscopy. Urine samples are also examined for post-translational modifications (e.g., glycosylation, sulfation, and cross-linking) to identify common features unique to amyloid proteins. Tissue samples are analyzed for biochemical and biophysical properties and for post-translational modifications in light chains.
Quality of life is assessed by the SF36 questionnaire.
