PY - 2023 T2 - Current Medical Diagnosis & Treatment 2023 AB - Amyloidosis is a relatively rare cause of nephrotic syndrome. It is caused by tissue deposition of an overproduced and abnormally-folded protein (amyloid). Several different proteins can form amyloid fibrils with renal deposition. Primary amyloidosis, or AL amyloidosis, is the most common form and is due to a plasma cell dyscrasia causing overproduction and deposition of monoclonal Ig light chains (see Chapter 13). Secondary amyloidosis, or AA amyloidosis, can rarely occur in chronic inflammatory disease such as rheumatoid arthritis, IBD, or chronic infection; in these cases, there is deposition of an acute phase reactant, serum amyloid A protein. Other less common forms of amyloidosis may also be encountered. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/18 UR - accessmedicine.mhmedical.com/content.aspx?aid=1193127645 ER -
