Diagnostic accuracy of monoclonal antibody based serum immunoglobulin free light chain immunoassays in myeloma cast nephropathy
UNLABELLED BACKGROUND The development of serum immunoassays for the measurement of immunoglobulin free light chains has led to a paradigm shift in the diagnosis, assessment and monitoring of patients with plasma cell dyscrasias. The impact of these immunoassays which employ polyclonal antibodies was most notable for those patients who were previously classified as non-secretory multiple myel...
متن کاملImportace of monoclonal immunoglobulin in Sjögren’s syndrome
Background: Sjögren’s syndrome is the second most common systemic autoimmune disease after rheumatoid arthritis, RA, with a prevalence of about 0.5% in the general population. It occurs primarily in perimenopausal women (at a ratio of women to men of 9: 1) Sjögren’s syndrome is characterized by lymphocytic infiltration to exocrine glands. The specific autoantibodies of this syndrome are against...
متن کاملMonoclonal gammopathies
Clinical background The finding of a monoclonal immunoglobulin in the serum defines the so-called monoclonal gammopathy. Monoclonal components are homogeneus immunoglobulins whole (intact) or fragmented, produced by a single expanded plasma cell clone. MCs present unique physicochemical homogeneity, which is reflected in their immunological homogeinity. Immunological homogeinity by electrophore...
متن کاملAnkylosing spondylitis and monoclonal gammopathies.
From 1960 to 1990, 557 patients with ankylosing spondylitis (428 men, 129 women) were diagnosed and indexed in the department of rheumatology. Monoclonal gammopathies were found in seven (five men, two women) patients (1.3%). With one exception, ankylosing spondylitis preceded monoclonal gammopathies by many years. The distribution of the isotypes of the mIg found in these seven patients was st...
متن کاملUnderstanding and identifying monoclonal gammopathies.
Monoclonal gammopathies reflect conditions in which abnormal amounts of immunoglobulins are produced by a clone that developed from a single pro-B germ cell. The condition may reflect a disease process or be benign. The primary purpose of this review is to emphasize routine clinical laboratory techniques that currently are recommended for use in identifying monoclonal gammopathies from serum an...
