    Dipartimento di Bioscienze, Università degli Studi di Milano, 20133, Milano, Italy.
    Light chain amyloidosis (AL), the most common systemic amyloidosis, is caused by the overproduction and the aggregation of monoclonal immunoglobulin light chains (LC) in target organs. Due to genetic rearrangement and somatic hypermutation, virtually, each AL patient presents a different amyloidogenic LC. Because of such complexity, the fine molecular determinants of LC aggregation propensity and proteotoxicity are, to date, unclear; significantly, their decoding requires investigating large sets of cases.

    A 67-year-old man was referred with a history of a right-sided neck lump and dysphonia, secondary to a lesion in the thyroid gland. After undergoing a total thyroidectomy, he was found to have an exceedingly rare combination of follicular carcinoma, insular carcinoma, thyrolipomatosis and an amyloid goitre in his thyroid gland. He subsequently underwent further radioactive iodine ablation and has been in remission. Read More

    Measurement of liver and spleen interstitial volume in patients with systemic amyloid light-chain amyloidosis using equilibrium contrast CT.
    Abdom Radiol (NY) 2017 Nov;42(11):2646-2651
    Centre for Medical Imaging, University College London, 250 Euston Road, London, NW1 2PG, UK.
    Objectives: To investigate equilibrium contrast-enhanced CT (EQ-CT) measurement of extracellular volume fraction (ECV) in patients with systemic amyloid light-chain (AL) amyloidosis, testing the hypothesis that ECV becomes elevated in the liver and spleen and ECV correlates with other estimates of organ amyloid burden.

    Methods: 26 patients with AL amyloidosis underwent EQ-CT, and ECV was measured in the liver and spleen. Patients also underwent serum amyloid P (SAP) component scintigraphy with grading of liver and spleen involvement. Read More

    Amyloidosis Cutis Dyschromica, a Rare Cause of Hyperpigmentation: A New Case and Literature Review.
    Pediatrics 2017 May;139(5)
    Department of General Pediatrics and Division of Pediatric Endocrinology and Diabetes, University Children's Hospital Heidelberg, Heidelberg, Germany; and.
    Amyloidosis cutis dyschromica is a rare form of primary cutaneous amyloidosis without systemic involvement and characterized by asymptomatic, progressive hyper- and hypopigmentation. We present the first case of a patient with amyloidosis cutis dyschromica diagnosed previously elsewhere as having Addison disease with generalized hyperpigmentation of the skin. This case suggests that in patients presenting with asymptomatic cutaneous dyschromia a skin biopsy for histopathological examination should be considered. Read More

    AL amyloidosis patients with low amyloidogenic free light chain levels at first diagnosis have an excellent prognosis.
    Blood 2017 08 26;130(5):632-642. Epub 2017 May 26.
    Amyloidosis Center and.
    The difference between involved minus uninvolved serum free light chains (dFLC) has been established as an invaluable hematologic parameter in systemic amyloid light chain (AL) amyloidosis. However, patients with an initial dFLC level <50 mg/L are currently deemed not evaluable for response to therapy. Therefore, we aimed to characterize this subgroup of patients and to define novel hematologic response parameters. Read More

    Common Fibril Structures Imply Systemically Conserved Protein Misfolding Pathways In Vivo.
    Angew Chem Int Ed Engl 2017 Jun 23;56(26):7510-7514. Epub 2017 May 23.
    Institute of Protein Biochemistry, Ulm University, Helmholtzstrasse 8/1, 89081, Ulm, Germany.
    Systemic amyloidosis is caused by the misfolding of a circulating amyloid precursor protein and the deposition of amyloid fibrils in multiple organs. Chemical and biophysical analysis of amyloid fibrils from human AL and murine AA amyloidosis reveal the same fibril morphologies in different tissues or organs of one patient or diseased animal. The observed structural similarities concerned the fibril morphology, the fibril protein primary and secondary structures, the presence of post-translational modifications and, in case of the AL fibrils, the partially folded characteristics of the polypeptide chain within the fibril.

    Pattern of acute glomerulonephritis in adult population in Dubai: A single-center experience.
    Saudi J Kidney Dis Transpl 2017 May-Jun;28(3):571-578
    Department of Nephrology, Dubai Hospital, Dubai Health Authority, Dubai, United Arab Emirates.
    Epidemiological data of renal diseases have great geographic variability throughout the world. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, clinical and pathological features of various glomerulonephritis (GN) in the United Arab Emirates (UAE). In a retrospective cross-sectional study, we analyzed 158 renal biopsies done in Dubai Hospital, UAE, between the years of 2005 and September 2014, with an aim to determine the prevalence rate and frequency of different pathological patterns of GN in adult patients who presented with proteinuria ± hematuria.
