RT Journal Article SR Electronic T1 New tools for detecting occult monoclonal gammopathy, a cause of secondary osteoporosis JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 273 OP 278 DO 10.3949/ccjm.77a.09091 VO 77 IS 4 A1 Faiman, Beth A1 Licata, Angelo A. YR 2010 UL http://www.ccjm.org/content/77/4/273.abstract AB Most patients with multiple myeloma or other monoclonal gammopathies present with anemia, hypercalcemia, or renal insufficiency. However, osteoporosis may be the first sign. Measuring the concentration and ratio of free light chains in the serum can help detect monoclonal gammopathy and help to differentiate myeloma-related bone loss from other secondary forms of osteoporosis.
