INTRODUCTION AND OBJECTIVE: The systematic analysis of a carpal transverse ligament (CTL) sample obtained during routine carpal tunnel syndrome (CTS) surgery may constitute a method of early diagnosis for systemic amyloidosis. MATERIAL AND METHODS: Prospective study carried out on 147 consecutive CTL samples collected from patients intervened for CTS at the University Hospital of León from April 2006 to May 2007. In those cases in which amyloid deposition was observed in the CTL sample, the study was completed with a fine needle aspiration biopsy (FNAB) of the subcutaneous fascia, using the Red Congo stain in both cases...

Intervention into amyloid deposition with anti-amyloid agents like the polyphenol Epigallocatechin-3-gallate (EGCG) is emerging as an experimental secondary treatment strategy in systemic light chain amyloidosis (AL). In both AL and Multiple Myeloma (MM), soluble immunoglobulin light chains (LC) are produced by clonal plasma cells, but only in AL they form amyloid deposits in vivo. We investigated the amyloid formation of patient-derived LC and their susceptibility to EGCG in vitro to probe commonalities and systematic differences in their assembly mechanisms...

BACKGROUND: Methadone is commonly administered for chronic pain relief and treatment of opioid dependence. Concurrent with its increased consumption, toxicities and fatalities have increased. One of the adverse effects of opioid analgesics, including methadone, is that of nephrotoxicity. Opioids can have an effect on renal function through several different mechanisms. METHODS: We searched common bibliographical databases for the terms methadone, toxicity, poisoning, kidney, renal, and nephrotoxicity and summarize our findings in this review...

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...

OBJECTIVES: The aim of this study was to access the prognostic implication of late gadolinium enhancement (LGE) in patients with systemic amyloidosis undergoing cardiac magnetic resonance (CMR). BACKGROUND: Cardiac amyloidosis confers significantly worse prognosis in patients with systemic amyloidosis. CMR imaging has emerged as an attractive noninvasive modality to diagnose cardiac involvement in patients with systemic amyloidosis. We performed a systemic review and meta-analysis to evaluate the prognostic role of LGE-CMR imaging in patients with systemic amyloidosis...

Cerebellar pathology has been related to presenilin 1 mutations in certain pedigrees of familial Alzheimer's disease. However, cerebellum tissue has not been intensively analyzed in transgenic models of mutant presenilins. Furthermore, the effect of the sex of the mice was not systematically analyzed, despite the fact that important gender differences in the evolution of the disease in the human population have been described. We analyzed whether the progression of amyloidosis in a double transgenic mouse, AβPP/PS1, is susceptible to aging and differentially affects males and females...

BACKGROUND: Cardiac amyloidosis (CA) is associated with a poor prognosis with the proposed mechanism of sudden cardiac death in the majority of patients being pulseless electrical activity. However, the incidence of ventricular arrhythmias (VA) and implantable cardioverter-defibrillator (ICD) indications in CA patients are unclear. We performed a detailed evaluation of our CA population undergoing ICD implantation and assessed appropriate ICD therapy and survival predictors. METHODS: We included consecutive patients from June 2008 to November 2014 in five centers...

Plasma cell dyscrasias, including monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma (MM), Waldenström macroglobulinemia (WM) and light chain AL amyloidosis, are characterized by clonal expansion of plasma cells which produce a vast amount of an immunoglobulin-derived M-protein. We noted that MGUS diagnosis often coincided with diagnoses of senile cataract and glaucoma and tested the associations of MGUS, MM, WM and AL amyloidosis with subsequent eye diseases identified from the Swedish patient registers between 1997 and 2012...

INTRODUCTION: Primary pulmonary lymphoma is a rare disease; diagnosis is often delayed because of atypical clinical presentation and slow progression. OBSERVATION: A 42-year-old woman consulted because of haemoptysis. Chest CT-scan showed multiple nodular calcified masses. A lung biopsy led to the diagnosis of pulmonary amyloidosis with pulmonary MALT lymphoma (mucosa-associated lymphoid tissue). The patient developed two paraneoplastic syndromes: a hypertrophic osteoarthropathy and mucinosis...

INTRODUCTION: In 5%-10% of patients with familial Mediterranean fever (FMF), colchicine is not effective in preventing inflammatory attacks. Another 5%-10% of patients are intolerant to effective doses of colchicine and experience serious side effects. Treatment with anti-interleukin-1 (IL-1) drugs may be an alternative for these patients, although it is not reimbursed for this indication in many countries. METHODS: We systematically searched PubMed, Web of Science, and Scopus for reports of anti-IL-1 treatment in FMF patients...

Multiple endocrine neoplasia type 2A (MEN2A) may be rarely associated with cutaneous lichen amyloidosis (CLA), a skin lesion located in the interescapular region. Here, we describe 3 MEN2A-related CLA kindred and perform a systematic review (SR) of the literature on clinical, biochemical and molecular characteristics of MEN2A-related CLA patients. Thirty-eight patients with MEN2A-related CLA followed at our institution were evaluated. The median age at MEN2A diagnosis in our cohort was 25 (13-41) years, 68 % were women and all harbored codon 634 RET mutations...

The spectrum of glomerular disorders with organized immunoglobulin (Ig) deposits is heterogeneous. It encompasses 2 mains categories: glomerulopathies with fibrillary deposits are mostly represented by immunoglobulinic amyloidosis (most commonly AL amyloidosis, characterized by monoclonal light chain deposits often of the lambda isotype), and pseudo-amyloid fibrillary glomerulonephritis in which deposits predominantly contain polyclonal IgG4. Glomerulopathies with microtubular deposits include cryoglobulinemic glomerulonephritis (type I and type II, with or without detectable serum cryoglobulin) and glomerulonephritis with organized microtubular monoclonal Ig deposits (GOMMID) also referred to as immunotactoid glomerulopathy...

Beta-2 microglobulin (β2m) is an amyloidogenic protein belongs to the immunoglobulin superfamily, responsible for the dialysis-related amyloidosis (DRA). Misfolding of β2m is a prerequisite to the formation of systemic amyloidosis that has an effect on the structure and function of the affected organ. The aim of our present study is to intensively explore the structural characterization of amyloid aggregation propensity of recently identified natural mutation D76N by applying the classical molecular dynamics (MD) approach...

PURPOSE OF REVIEW: These recommendations highlight recent experience in genetic counselling for the severe autosomal-dominant, late-onset transthyretin familial amyloid polyneuropathy (TTR-FAP) disease, and present a structured approach towards identification and monitoring of asymptomatic carriers of the mutated gene. RECENT FINDINGS: The effectiveness of current treatment options is still limited in patients with TTR-FAP beyond stage I. Diagnosis in the early stages of TTR-FAP is essential to prevent or delay the progression of disease...

The most dreaded complication of familial Mediterranean fever (FMF) is amyloidosis; controversy exists as to what acute phase reactant (APR) should be monitored in these patients. To analyze the best acute phase reactant for FMF follow-up to help guide physicians to decide on what APR parameter to use, we also attempted to define the best APR in predicting the complications of FMF, specifically the development of amyloidosis. Systematic review based on a sensitive search to capture studies that: (1) included FMF patients; (2) measured serum amyloid A (SAA), CRP (C-reactive protein), proteinuria, or ESR (erythrocyte sedimentation rate); (3) amyloidosis were the outcome measure; (4) sensitivity, specificity, predictive value, and other performance parameters could be calculated; and (5) had a longitudinal design...

BACKGROUND: Localised immunoglobulin light-chain amyloidosis, involving one type of tissue, is rare. Little systematic data exists regarding clinical presentations, course or outcomes, or risk of progression to systemic amyloidosis. We aimed to report clinical features and outcomes of a large series of patients with localised light-chain amyloidosis. METHODS: We examined data for all patients with localised amyloidosis who were diagnosed, assessed, and followed at the UK National Amyloidosis Centre (NAC) between Jan 2, 1980, and Dec 15, 2011, from the NAC database and written records...
