OBJECTIVE: In epidemiological studies of amyloid A (AA) amyloidosis from Turkey, the most frequently cause was familial Mediterranean fever (FMF) and it occurs generally in young age population. However, there are no sufficient data regarding aetiology, clinical presentation and prognosis of renal AA amyloidosis in advanced age patients. In this study, we aimed to investigate demographic, clinical presentation, aetiology and outcomes of adults aged 60 years or older patients with biopsy-proven renal AA amyloidosis...

Background: Intravenous drug use is associated with progressive kidney disease of several aetiologies. It is associated with behavioural and lifestyle characteristics that make the provision of renal replacement therapies (RRTs) challenging. We observed that patients who use intravenous drugs [people who inject drugs (PWID)] present late to renal services and struggle to engage with treatment. We describe the experience of a UK centre providing renal services to a mixed city and rural population...

BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

Light chain (AL) amyloidosis is caused by a usually small plasma-cell clone that is able to produce the amyloidogenic light chains. They are able to misfold and aggregate, deposit in tissues in the form of amyloid fibrils and lead to irreversible organ dysfunction and eventually death if treatment is late or ineffective. Cardiac damage is the most important prognostic determinant. The risk of dialysis is predicted by the severity of renal involvement, defined by the baseline proteinuria and glomerular filtration rate, and by the response to therapy...

RATIONALE: Dialysis-related amyloidosis (DRA) can present rheumatic manifestations in patients on long-term hemodialysis. Typical articular symptoms with DRA involve carpal-tunnel syndrome, effusion in large joints, spondyloarthropathy, or cystic bone lesions, which are usually with non-inflammatory processes. PATIENT CONCERNS: A 64-year-old man on hemodialysis for >30 years was admitted because of intermittent fever, polyarthritis, and elevated serum C-reactive protein (CRP) level, which was continuous for 2 years...

Amyloid fibrillation has been implicated in many neurodegenerations, dialysis-related amyloidosis, type II diabetes and more than 30 other amyloid-related diseases. Nanomaterials as potential inhibitors of amyloid fibrillation have attracted increasing interests. In the present study, the effects of gold nanorods (AuNRs) and nanoparticles (AuNPs) on amyloid fibrillation were investigated using hen egg white lysozyme (HEWL) as a model system. Our results indicated that AuNRs and AuNPs, especially AuNRs, present significant inhibitory effects on HEWL amyloid fibril formation during all the kinetic processes, from nucleation to elongation and equilibration stages...

BACKGROUND: Outcome data on aortic valve replacement in patients with amyloidosis are limited. To address this issue, we reviewed our experience of patients with amyloidosis who underwent aortic valve replacement. METHODS: We retrospectively reviewed the records of 16 patients with amyloidosis who underwent aortic valve replacement between May 2000 and February 2017. RESULTS: The cohort comprised 11 males (69%) and 5 females (31%). The median patient age was 76 years (interquartile range [IQR], 71-82 years), and Society of Thoracic Surgeons predicted rate of mortality was 5...

Growth differentiation factor-15 (GDF-15) improves prognostication in patients with cardiovascular disorders in addition to conventional cardiac markers (N-terminal pro B-type natriuretic peptide [NT-proBNP], troponins [Tns]) and has shown prognostic value in patients with renal diseases. In patients with light chain (AL) amyloidosis, cardiac involvement is the major determinant of prognosis, and cardiac markers define prognosis, whereas biomarkers of renal involvement stratify renal risk. We explored the prognostic importance of serum level of GDF-15 in patients with AL amyloidosis in 2 independent cohorts...

Delayed bowel erosion by peritoneal dialysis catheter is rare with fewer than thirty cases having been reported in the literature. This complication is usually encountered when the catheter is kept dormant. Two cases have also been reported with catheters in active use. The risk factors for bowel erosion include immunosuppression, diverticulosis, and amyloidosis. An 80-year-old male with chronic kidney disease Stage 5 due to hypertensive nephrosclerosis underwent chronic ambulatory peritoneal dialysis catheter insertion...

BACKGROUND/AIMS: The deposition of β2-microglobulin induced by reactive inflammation causing carpal tunnel syndrome (CTS) is one of the complications of dialysis-related amyloidosis in maintenance hemodialysis (MHD) patients. Air pollution levels, especially particulate matter with an aerodynamic diameter of <2.5 mm (PM2.5), have significantly been associated with the elevation of systemic inflammatory markers. There is no previous research on possible associations between CTS and PM2...

Renal impairment (RI) is a common complication of multiple myeloma (MM), which is presented as chronic kidney disease (CKD) or acute kidney injury (AKI). The typical pathological feature is cast nephropathy. Presently international system staging (ISS) is used in evaluating MM. Although the classic Durie-Salmon staging system could be still used in clinical practice, it may miss out some patients with renal impairment. For evaluations of RI in MM patients with CKD, it's recommended to assess the estimated glomerular filtration rate (eGFR) by creatinine based formula CKD-epidemiology collaboration (EPI) or modification of diet in renal disease(MDRD) and to stage the renal injuries according to 2013 Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines...

Cerebral β-amyloidosis is a major feature of Alzheimer's disease (AD), characterized by the accumulation of β-amyloid protein (Aβ) in the brain. Several studies have implicated lipid/lipoprotein metabolism in the regulation of β-amyloidosis. In this regard, HDL (High Density Lipoprotein)-based therapies could ameliorate pathological features associated with AD. As apolipoprotein J (ApoJ) is a natural chaperone that interacts with Aβ, avoiding its aggregation and toxicity, in this study we propose to prepare reconstituted rHDL-rApoJ nanoparticles by assembling phospholipids with recombinant human ApoJ (rApoJ)...

Dialysis-related amyloidosis (DRA) is a severe complication of hemodialysis that results in progressive destruction of bones and joints. Elevated concentrations of the β2 -microglobulin (β2 m) level in the serum of subjects on hemodialysis promote the formation of amyloid fibrils in osteoarticular tissues. β2 m lacking the N-terminal six residues of the mature protein (ΔN6β2 m) constitutes 25-30% of β2 m in ex vivo DRA amyloid. Unlike full-length wild-type β2 m, ΔN6β2 m forms amyloid fibrils at neutral pH in vitro...

Hematologic response criteria in light chain (AL) amyloidosis require the difference in involved and uninvolved free light chains (dFLC) to be at least 5 mg/dl. We describe the clinical presentation and outcomes of newly diagnosed amyloidosis patients with dFLC <5 mg/dl (non-evaluable dFLC; 14%, n=165) compared with patients with dFLC ⩾5 mg/dl (evaluable dFLC; 86%, n=975). Patients with non-evaluable dFLC had less cardiac involvement (40% vs 80%, P<0.001), less liver involvement (11% vs 17%, P=0...

The bone marrow basically consists of red blood-forming bone marrow and yellow fat. In the skeleton, there is an age-dependent distribution of these two parts. In the context of medical interventions or therapies, bone marrow changes can occur, whereby the normal bone marrow can basically be replaced by fat, edema, or fibrosis/sclerosis. Here, specific signal intensities and patterns are shown in imaging. After irradiation therapies, edematous changes, hemorrhages, and osteoradionecroses are observed. Likewise, insufficiency fractures, impairment of the growth gaps, or the development of tumors is possible...

BACKGROUND AND PURPOSE: Osteoarticular manifestations of beta-2 microglobulin amyloidosis are often diagnosed in long-term dialyzed patients. However, spinal involvement is rare (10-25% of patients), and generally not associated with neurological deterioration. Compression of the spinal cord or roots is extremely rare, and probably under-recognized. METHODS: The authors describe three cases of spinal stenosis presenting with neurological signs in long-term dialyzed patients, prospectively collected over 2 years in two different institutions and treated by surgical decompression...

BACKGROUND: No effective treatment is currently available and dialysis related amyloidosis continues to be invalidating in long-term dialysis patients. A recent case series reported reduction of osteoarticular pain on doxycycline treatment, extending the indications of this drug, used in other uncommon forms of amyloidosis, to dialysis patients. Explanations of the antalgic effect were the anti-inflammatory properties and anti-coiling effects of tetracycline. CASE PRESENTATION: Our report regards a 54-year-old woman, who was never transplanted and has been on hemodialysis and hemodiafiltration for overall 37 years, due to renal hypoplasia...

The kidney is the most common organ affected by immunoglobulin light-chain (AL) amyloidosis and monoclonal immunoglobulin deposition disease (MIDD), often leading to end-stage renal disease (ESRD). High-dose melphalan and stem cell transplantation (HDM/SCT) is effective for selected patients with AL amyloidosis, with high rates of complete hematologic response and potential for improved organ dysfunction. Data on tolerability and response to HDM/SCT in patients with ESRD due to AL amyloidosis and MIDD are limited...
