    Concurrent structural and biophysical traits link with immunoglobulin light chains amyloid propensity.
    Sci Rep 2017 Dec 1;7(1):16809. Epub 2017 Dec 1.
    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.

    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

    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.

    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.

    Department of Dermatology, University of California, San Francisco, USA.
    Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent painful nodules and abscesses involving intertriginous areas. Repeated episodes of profound inflammation in HS can lead to a number of complications, causing significant morbidity and decreasing quality of life. Complications of HS may affect the skin alone or may have systemic impact. Read More
