light chain deposition disease


light chain disease

A nephropathy which presents with nephrotic range proteinuria and rapidly progressive renal failure due to deposition of electron-dense material within tubular and glomerular basement membranes.
Clinical findings
Nephrotic syndrome, heart failure, arrhythmias, liver disease, anorexia, nausea, weight loss, anaemia, increased creatinine, and neurologic disease; similar clinical findings occur in heavy chain deposition.

light chain deposition disease

Bence-Jones myeloma, light chain disease Oncology A paraproteinemia linked to renal amyloidosis, which occurs in 20% of Pts with immunoproliferative disorders; both are characterized by deposits of fibrillar and nonfibrillar monoclonal light chains in various tissues Clinical Rapidly progressive renal failure due to renal tubular blockage by Bence-Jones proteins, nephrotic syndrome, heart failure, arrhythmias, liver disease, neurologic disease; similar clinical findings are associated with heavy chain deposition
