BACKGROUND: Longer life expectancy is associated with an increasing prevalence of kidney disease. Aging itself may cause renal damage, but the spectrum of kidney disorders that affect elderly patients is diverse. Few studies, mostly form US, Asia and West Europe found differences in the prevalence of some types of kidney diseases between elderly and younger patients based on renal biopsy findings, with varied proportion between glomerulopathies and arterionephrosclerosis as a dominant injury found...

In addition to general skin changes like pallor or dryness and the frequent, often excruciating nephrogenic pruritus, specific diseases in patients with renal failure may occur. Acquired perforating dermatoses are usually also highly pruritic. Calciphylaxis is a severe disease with poor prognosis. Nonhealing wounds with superinfection and progression to sepsis are characteristic. Bullous lesions can be caused by disturbances in porphyrin metabolism. Nephrogenic systemic fibrosis is a disease which was first described in 2000...

We report the case of a 73-year-old man with a documented (renal biopsy) light-chain amyloidosis (AL) imaged with F-AV-1 (F-florbetaben) compared with a volunteer. A cardiac amyloidosis was suspected. As it was an AL and not a transthyretin amyloidosis, F-FDG and F-florbetaben PET/CT were preferred to bone scan. F-FDG scintigraphy showed a focal cardiac hypermetabolism. In addition of the heart, F-florbetaben scintigraphy showed an intense spleen and thyroid pathologic uptake and a moderate salivary gland and kidney uptake...

OBJECTIVES: Familial Mediterranean fever (FMF) is a hereditary periodic disease characterised by recurrent attacks of fever and serositis. The most devastating complication of FMF is amyloidosis (AA) affecting mainly the kidneys. Aim of the study is to search for correlations between the MEFV genotype and the SAA polymorphisms with the clinical manifestations of FMF and the occurrence of amyloidosis in a large cohort of Armenian patients. METHODS: Information about the MEFV mutations, SAA polymorphisms and FMF clinical features, were obtained for 1017 FMF patients, from the database of the Center of Medical Genetics in Yerevan...

Amyloidosis is characterized by pathological deposition of abnormal protein aggregates in various tissues, AL protein being the commonest. ALECT 2 is the newest protein described, having a predisposition to affect the kidneys, sometimes the liver and rarely other organs. We present a case of renal amyloid ALECT 2 due to leucocyte cell derived chemotaxin 2, a novel amyloidogenic protein. The patient presented with mild proteinuria, scattered plasma cells on bone marrow examination and altered kappa/lambda ratio with associated cytogenetic abnormality of der7q add(7)...

BACKGROUND: Secondary bladder amyloidosis is an extremely rare disease, resulting from a chronic systematic inflammatory disorder associated with amyloid deposits. Although uncommon in Japan, familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever of short duration and serositis and is frequently associated with systemic amyloidosis. Here, we present a case of a Japanese patient complaining of fever and macroscopic hematuria after a living donor renal transplantation...

Anti-tumor necrosis factor-α (TNFα) therapy has improved the prognosis of many chronic inflammatory diseases. It appears to be well-tolerated by liver-transplant patients. However, their use and their safety in kidney-transplant patients have yet to be determined.In this retrospective study, we identified 16 adult kidney-transplant patients aged 46.5 years (34-51.8) who received anti-TNFα therapy from 7 kidney transplantation centers. The indications for this treatment included: chronic inflammatory bowel disease (n = 8), inflammatory arthritis (n = 5), AA amyloidosis (n = 1), psoriasis (n = 1), and microscopic polyangiitis (n = 1)...

According to previous studies in captive cheetah ( Acinonyx jubatus ) populations, one of the most threatening diseases besides amyloidosis, myelopathy, veno occlusive disease, and gastritis, is renal failure. Contrary to captive cheetahs in North America and South Africa, morphological data concerning renal lesions in the cheetah European Endangered Species Program (EEP) are lacking. This study details the histological characterization as well as immunohistochemical and morphometrical analysis of nephropathies in 35 captive cheetahs from the EEP, which were necropsied between 1985 and 2003...

Kimmelstiel and Wilson originally described nodular glomerulosclerosis as the pathognomonic lesion of diabetic nephropathy. Nevertheless, nodular glomerulosclerosis pattern can rarely occur in non-diabetic patients. In such cases, the differential diagnosis includes membranoproliferative glomerulonephritis, light or heavy chain deposition disease, amyloidosis, fibrillary and immunotactoid glomerulonephritis and chronic hypoxic or ischemic conditions. In cases that the above entities cannot be proven, the term idiopathic nodular glomerulosclerosis is given...

Orthotopic liver transplantation (LT) was implemented as the inaugural disease-modifying therapy for hereditary transthyretin (ATTR) amyloidosis, a systemic amyloidosis mainly affecting the peripheral nervous system and heart. The first approach to pharmacologic therapy was focused on the stabilization of the TTR tetramer; following that new advent LT was assumed as the second step of treatment, for those patients whose neuropathy becomes worse after a course of pharmacologic therapy. The renal disease has been ignored in hereditary ATTR amyloidosis...

Galectins are evolutionary conserved β-galactoside binding proteins with a carbohydrate-recognition domain (CRD) of approximately 130 amino acids. In mammals, 15 members of the galectin family have been identified and classified into three subtypes according to CRD organization: prototype, tandem repeat-type and chimera-type galectins. Galectin-3 (gal-3) is the only chimera type galectin in vertebrates containing one CRD linked to an unusual long N-terminal domain which displays non-lectin dependent activities...

Mutations in gelsolin are responsible for a systemic amyloidosis first described in 1969. Until recently, the disease was associated with two substitutions of the same residue, leading to the loss of the calcium binding site. Novel interest arose in 2014 when the N184K variant of the protein was identified as the etiological agent of a novel kidney-localized amyloidosis. Here we provide a first rationale for N184K pathogenicity. We show that the mutation induces a destabilization of gelsolin second domain, without compromising its calcium binding capacity...

The clinical manifestations of primary systemic amyloidosis with the involvement of a variety of organs, such as the kidney, heart, peripheral nervous system, liver, and so forth, are varied, complicated and nonspecific. The mucocutaneous manifestations, sometimes as the symptom in the early stages of disease, may provide an important clue for the diagnostic suspicion. Here we described a case of primary systemic amyloidosis with the history of Type 2 diabetes mellitus (T2DM) for nine years who had recurrent periorbital purpura in the initial stage, followed by nephrotic syndrome...

INTRODUCTION: Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by self-limited recurrent attacks of fever and serositis. Patients may develop renal amyloidosis. Colchicine prevents attacks and renal amyloidosis. Five to 10 % of the patients with FMF are resistant or intolerant to colchicine. CASE DESCRIPTION: Herein, we reported our experience with clinical-laboratory features and treatment responses of a pediatric FMF patient with amyloidosis treated with canakinumab...

BACKGROUND: Amyloid A (AA) amyloidosis is a multisystemic, progressive, and severe disease. Renal involvement is a prominent feature of the disease, and the outcome of patients on dialysis is poor. We aimed to analyze the outcomes of kidney transplantation in patients with AA amyloidosis in comparison with chronic glomerulonephritis (CGN). METHODS: Charts of patients who underwent kidney transplantation between 1988 and 2012 were reviewed; 41 patients with AA amyloidosis were identified, and 41 age- and sex-matched control patients with chronic CGN were included...

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 loss and presented clinical signs of hepatopathy. Clinical workup revealed portal hypertension with ascites, hemorrhoids, and esophageal varices...

Bruno Moulin
Cardiorenal syndromes refer to clinical and metabolic consequences of acute and chronic heart failure or kidney disease on other organ. Recent studies have further clarified the pathophysiological mechanisms behind the different types of cardiorenal syndromes and propose a new classification. The cardiorenal syndrome type 1 corresponds to an acute heart failure (cardiogenic shock, acute decompensated congestive heart failure) which induces acute renal dysfunction. In the cardiorenal syndrome type 2 heart failure is chronic (congestive heart failure) and induces chronic kidney damages in the long-term...

Amyloidosis is a disease characterized by the deposition of non-soluble fibrous protein in multiple tissues with a number of possible causes. This protein deposition can occur in any tissue, yet is most commonly seen in kidneys, heart, and gastrointestinal tracts. However, invasion to bone tissues is not often reported. The deposition of amyloid proteins in bone tissues may result in joint pain and pathological fractures; it is important to elucidate the causes and detect early to determine prognosis and treat optimally...
