Prolonged injection of casein results in systemic amyloidosis in mice with impaired hepatic functions due to excessive serum amyloid A (SAA) fibril deposition in liver, spleen, and kidney. We have shown that systemic amyloidosis results in accumulation of SAA fibrils in the brain. The study carried out radiolabeling, Congo red stain, Immuno histochemical studies to source the SAA fibrils that a...

BACKGROUND Amyloidosis represents a group of different diseases characterized by extracellular accumulation of pathologic fibrillar proteins in various tissues and organs. Severe amyloid deposition in the liver parenchyma has extrahepatic involvement predominantly in the kidney or heart. We evaluated the effect of ursodeoxycholic acid, in four patients with severe hepatic amyloidosis of differe...

Primary systemic amyloidosis (AL) is an uncommon disease characterized by the extracellular deposition of a protein with a beta-fibrillar structure, consisting of monoclonal immunoglobulin light chains, lambda or kappa (ratio of lambda to kappa, 3:1). In systemic amyloidosis liver involvement is frequent but it rarely has clinical importance. The massive and localized liver deposition of amyloi...

Amyloidosis comprises a group of diseases that occurs in five to nine cases per million patients per year worldwide irrespective of its classification. Although the hepatic involvement in primary amyloidosis is frequent, the clinical manifestations of liver amyloidosis are mild or even absent. The authors report the case of an aged man who complained of diffuse abdominal pain and marked weight ...

Liver transplantation has been used in treatment of transthyretin amyloidosis, and some patients undergo domino liver transplantation (DLT) with explanted liver being transplanted to another patient with liver failure as the liver is otherwise usually functionally normal. Until end of 2015, there were 1154 DLT performed worldwide. DLT for transthyretin amyloidosis is associated with the risk of...

__________________________________________________________________________________ Abstract. Apart from the usual morphological changes in the liver of intravenous heroin users such as vesicular and fatty changes, various forms of viral hepatitis and development of cirrhosis, the onset of amyloidosis, the change in the number of hepatic sinusoidal macrophages, and dysplastic changes are of part...

Sir, Hereditary amyloidosis is a rare disorder associated with mutations encoding seven proteins: transthyretin, apolipoproteins AI and AII, gelsolina, cystatin C, lysozyme and fibrinogen A. We report a case of renal amyloidosis affecting six members of a family, associated with a novel non-stop mutation in the apolipoprotein AII gene. A 42-year-old Caucasian male with nephrotic syndrome and re...

Introduction: Amyloidosis has two principle types: multiple myeloma-associated (AL) and amyloidassociated amyloidosis (AA). Both types can be local or systemic and can often involve the liver. Hepatic amyloidosis carries a poor prognosis, but commonly presents with a more gradual time course of evolving hepatomegaly and elevated serum alkaline phosphatase. This casereport involves an unusual pr...

Background In transthyretin (TTR) cardiac amyloidosis, myocardial deposition and accumulation of liver-derived TTR fibrils results in heart failure and death. The hereditary form of the disease is caused by mutations in the TTR gene and presents as familial amyloidotic cardiomyopathy (FAC), whereas senile systemic amyloidosis (SSA) is an acquired disease caused by wild-type TTR. There are curre...

In mouse senile amyloidosis, apolipoprotein (Apo) A-II is deposited extracellularly in many organs in the form of amyloid fibrils (AApoAII). Reduction of caloric intake, known as caloric restriction (CR), slows the progress of senescence and age-related disorders in mice. In this study, we intravenously injected 1 μg of isolated AApoAII fibrils into R1.P1-Apoa2c mice to induce experimental amyl...
