Of the variety of immunoglobulin related amyloidosis (AL), immunoglobulin M (IgM) related AL represents only 6 to 10% of affected patients, and the majority of these cases are associated with underlying non-Hodgkin's Lymphoma including Waldenström's macroglobulinemia (WM). Ibrutinib, acalabrutinib, and zanubrutinib are Bruton tyrosine kinase (BTK) inhibitors approved for certain indolent B cell non-Hodgkin's lymphoma (NHL). BTK is a nonreceptor kinase involved in B-cell survival, proliferation, and interaction with the microenvironment. Read More

Kidney involvement in immunoglobulin-related amyloidosis (AIg) is common. Although patients with renal-limited AIg tend not to have the high mortality that patients with cardiac amyloidosis have, they do experience significant morbidity and impact on quality of life. The complexity of the pathogenesis remains incompletely understood. Read More

Monoclonal gammopathy of renal significance (MGRS) is characterized by the nephrotoxic monoclonal immunoglobulin (MIg) secreted by an otherwise asymptomatic or indolent B-cell or plasma cell clone, without hematologic criteria for treatment. The spectrum of MGRS-associated disorders is wide, including non-organized deposits or inclusions such as C3 glomerulopathy with monoclonal glomerulopathy (MIg-C3G), monoclonal immunoglobulin deposition disease, proliferative glomerulonephritis with monoclonal immunoglobulin deposits and organized deposits like immunoglobulin related amyloidosis, type I and type II cryoglobulinaemic glomerulonephritis, light chain proximal tubulopathy, and so on. Kidney biopsy should be conducted to identify the exact disease associated with MGRS. Read More

The clinicopathological characteristics of kidney infiltration in B-cell lymphoproliferative disorders remain poorly described. We retrospectively studied 52 adults with biopsy-proven malignant B-cell kidney infiltration, including Waldenström's macroglobulinemia (n=21), chronic lymphocytic leukemia (n=11), diffuse large B-cell lymphoma (DLBCL) (n=8), other lymphoma (n=11), and multiple myeloma (n=1). Kidney disease varied according to the underlying lymphoproliferative disorder. Read More

The renal deposition of monoclonal immunoglobulins can cause severe renal complications in patients with B cell and plasma cell lymphoproliferative disorders. The overproduction of a structurally unique immunoglobulin can contribute to the abnormal propensity of monoclonal immunoglobulins to aggregate and deposit in specific organs. A wide range of renal diseases can occur in multiple myeloma or monoclonal gammopathy of renal significance, including tubular and glomerular disorders with organized or unorganized immunoglobulin deposits.

The heart is commonly involved in various forms of amyloidosis and cardiomyopathy is a major cause of morbidity and mortality in these patients. Diagnosis of cardiac amyloidosis is often delayed due to nonspecific presenting symptoms and failure to recognize early signs of amyloid heart disease on routine cardiac imaging. Treatment of cardiac amyloidosis depends upon the type of amyloid protein. Read More

This paper is an attempt to assess the usefulness of ultrasonography in the diagnosis of the enlargement of the tongue (macroglossia). The role of sonography in diagnosing local pathologies of the tongue, such as neoplasms, abscesses or granulomas, has been well-established for 20 years. Rarely is its usefulness considered with respect to diagnosing macroglossia with concomitant systemic diseases. Read More

Summary: The classification of protein sequences obtained from patients with various immunoglobulin-related conformational diseases may provide insight into structural correlates of pathogenicity. However, clinical data are very sparse and, in the case of antibody-related proteins, the collected sequences have large variability with only a small subset of variations relevant to the protein pathogenicity (function). On this basis, these sequences represent a model system for development of strategies to recognize the small subset of function-determining variations among the much larger number of primary structure diversifications introduced during evolution.

Objective: Immunoglobulin-related free light chains (FLCs) in serum have recently become quantitatively detectable using the nephelometric assay in plasma cell disorders, including multiple myeloma and AL amyloidosis. To investigate whether FLCs are useful as a diagnostic and therapeutic marker in Japanese patients with primary systemic AL amyloidosis, we determined these values in serum before and after chemotherapy.

Patients And Methods: The serum FLC analysis was carried out in 25 patients with primary systemic AL amyloidosis (mean age, 60. Read More

Localized amyloidosis in the ureter is a rare condition, in which immunoglobulin light chain is locally synthesized, causing thickening of ureteric walls by deposits of immunoglobulin-related amyloid. Since the clinical features of ureteral amyloidosis with ureteric stricture and/or hydroureteronephrosis closely resemble those of malignancy involving the ureters, nephroureterctomy is usually performed for this disease. We describe two aged patients with localized amyloidosis on the bilateral ureters. Read More

Plasma cell disorders are associated with a wide spectrum of neurologic complications that predominantly involve the peripheral nervous system. Distinct clinical syndromes have been recognized, and antibodies to several glycoproteins of the peripheral nervous system have been identified. The main clinical, laboratory, immunologic, and pathologic features of neurologic complications that occur in patients with monoclonal gammopathies of unknown significance, multiple myeloma, plasmacytoma, plasma cell leukemia, Waldenstrom's macroglobulinemia, and immunoglobulin-related amyloidosis are summarized in this review.

Here we present an unusual case of a 53-year old patient presenting AL-kappa amyloidosis with diffuse-type amyloidosis of lungs, lymph nodes and pleura. The underlying pathology was a B-cell immunoglobulin-secreting non-Hodgkin lymphoma, as proven by the presence of a monoclonal B-cell population in the bone marrow. Diffuse parenchymal infiltration of the lungs is extremely rare in non-systemic amyloidosis, with only 4 previous cases having been reported in the English literature. Read More

Background And Methods: Familial occurrence of immunoglobulin-related (AL) amyloidosis has occasionally been reported. In this work we describe the concomitance of systemic amyloidosis and monoclonal gammopathy (one case of Waldenström's macroglobulinemia and two cases without multiple myeloma or related diseases) in three Italian siblings, two males and one female.

Results And Conclusions: All of them showed a common pattern of polyneuropathy to different degrees; two presented a sicca syndrome and one also suffered from nephropathy. Read More

Up to 37% of cases of generalized primary and secondary amyloidosis demonstrate lymph node involvement. Lymph node involvement as the presenting feature of generalized amyloidosis is uncommon. Isolated lymph node amyloidosis (that is, with no extranodal amyloidosis) is exceedingly rare; review of the literature reveals only two reported cases. Read More

Immunoglobulin- or multiple myeloma-associated amyloidosis has been distinguished by the tissue deposition of Congophilic, fibrillar protein consisting of light chains or light-chain fragments (AL amyloidosis). We now report the isolation and characterization of another form of immunoglobulin-associated amyloid obtained from a patient who had extensive systemic amyloidosis and in whom the amyloid deposits consisted not of light chains but rather of an unusual form of heavy chain. This component, isolated from splenic amyloid extracts, represented an internally deleted IgG1 heavy chain as evidenced by immunochemical, electrophoretic, and amino acid sequence analyses.

We report the occurrence of immunoglobulin-related amyloidosis (AL) in three separate families, each family having two members affected. None of the six patients had evidence to suggest the presence of familial amyloidosis (AF). Previously, immunoglobulin-related amyloidosis (AL) was considered to be a sporadic disease process.

We studied three patients with amyloidosis who had a significant hemorrhagic disorder secondary to increased fibrinolysis. In two of the three patients, bleeding was one of the major initial problems; in the other patient, bleeding occurred later in the course of the disease. All three patients were men with primary or myeloma-associated amyloidosis (ie, immunoglobulin-related or AL). Read More

In order to classify the underlying disorder in four patients with biopsy-proven amyloidosis without overt monoclonal gammopathy, the cytoplasmic immunoglobulin (Ig) distribution of bone marrow plasma cells was evaluated using direct immunofluorescence microscopy. This procedure revealed the presence of a monoclonal proliferation of light chain containing plasma cells, and thus led to the diagnosis of immunoglobulin-related amyloidosis. Read More
