We read with interest the article by Esterbrook et al on cardiac amyloidosis. Authors demonstrated very excellent clinical presentation and a challenging diagnostic work-up in a patient with cardiac amyloidosis presenting with cough and breathlessness. However, we would like to discuss on another possible straightforward diagnostic approach for this case. A combination of poor R progression on ...
Although recent decades have provided significant advances in our understanding of the pathology and pathogenesis of AA amyloidosis, the mechanism and etiopathological factors promoting amyloidosis are largely unknown (Elimowa et al., 2009). Its pathogenesis is multifactorial, involving many variables such as primary structure of the precursor protein, acute-phase response, the presence of non-...
BACKGROUND Cardiac amyloidosis is characterized by amyloid infiltration resulting in extracellular matrix disruption. Amyloid cardiomyopathy due to immunoglobulin light chain protein (AL-CMP) deposition has an accelerated clinical course and a worse prognosis compared with non-light chain cardiac amyloidoses (ie, forms associated with wild-type or mutated transthyretin [TTR]). We therefore test...
BACKGROUND The incidence of amyloidosis is difficult to determine because the disease is often undiagnosed or diagnosed incorrectly. In Polish studies, there are no statistics and analyses of the factors that may influence the development of amyloidosis in patients with multiple myeloma. OBJECTIVES The goal of this study was to estimate the incidence of AL amyloidosis in MM patients in Lower ...
Systemic AA amyloidosis is a relatively rare complication of chronic inflammatory disorders, e.g. rheumatoid arthritis, ankylosing spondylitis, familial Mediterranean fever and other autoinflammatory syndromes, Crohn’s disease, malignancies and recurrent infections. Isolated case of AA amyloidosis have been reported in many other chronic diseases, including systemic vasculitides, diffuse connec...
BACKGROUND Light chain (AL) amyloidosis is a rare disease characterized by misfolded amyloid protein deposits in tissues and vital organs, and little is known about the burden of AL amyloidosis on health-related quality of life. This study aimed to quantify the burden of AL amyloidosis in terms of health-related quality of life in a diverse, community-based sample of AL amyloidosis patients. ...
There are no treatment modalities, which were proven to prevent the deposition of amyloid, proteinuria, and loss of renal function due to amyloidosis. Anti-tumor necrosis factor agents (anti-TNFs) were shown to decrease the production of serum amyloid A protein.We aimed to evaluate the long-term efficacy and safety of anti-TNFs in secondary (AA) amyloidosis patients treated in a single center.T...
Two hundred and thirty-three patients with renal amyloidosis were studied in an attempt to identify the incidence and pattern of the disease in northern India. The incidence of amyloidosis was 1.01% of 6431 post-mortems and 8.4% of 1980 renal biopsies from patients who presented with clinical evidence of glomerular disease. Two hundred and three patients (87.1%) had secondary amyloidosis, 22 (9...
BACKGROUND AND AIMS The liver is frequently involved in amyloidosis but the significance of hepatic amyloid has not been systematically studied. We have previously developed scintigraphy with 123I serum amyloid P component (123I-SAP) to identify and monitor amyloid deposits quantitatively in vivo and we report here our findings in hepatic amyloidosis. METHODS Between 1988 and 1995, 805 patien...
The amyloidoses are a group of deposition diseases in which the tissue deposits are composed of protein fibrils. These fibrils are the result of aggregation of specific precursor proteins into ordered structures which are resistant to proteolytic digestion and solubilisation. The ordered structure of the fibrils causes the deposits to be birefringent and, when histological sections are stained ...
