Light chain deposition disease (LCDD) is a rare condition characterized by the deposition of specific proteins (monoclonal light chains) in the kidneys and other organs. Light chains are used to make antibodies that the body needs to fight infection. People with LCDD make too many light chains, which get deposited in many body tissues. While LCDD can occur in any organ, the kidneys are always involved. Signs and symptoms of LCDD may include protein in the urine ; decreased kidney function; and/or nephrotic syndrome. Rarely, a person with LCDD may have symptoms from cardiac (heart) or liver involvement. The underlying cause of LCDD is unknown. It is often associated with multiple myeloma. LCDD may progress to multiple myeloma, or it may be present with multiple myeloma when it is first diagnosed. The goal of treating LCDD is to slow the production of light chains and their damage to organs. Treatment may include chemotherapy with a drug called Bortezomib ; autologous stem cell transplantation ; immunomodulatory drugs; and/or kidney transplant. If untreated, end-stage renal disease occurs in 70% of cases.
4 clinical trials registered. Interventions under study include other interventions and drug therapy. Pipeline includes 1 PHASE3, 1 PHASE1. Research is primarily sponsored by academic and government institutions.
58 publications have been identified in PubMed for light chain deposition disease. Research spans Case Report / Case Series (57%), Review / Meta-Analysis (19%), and Epidemiology / Natural History (12%).
