Deregulation of long noncoding RNAs ANCR, TINCR, HOTTIP and SPRY4-IT1 in plasma of systemic sclerosis patients: SPRY4-IT1 as a novel biomarker of scleroderma and its subtypes.

Cytokine 2020 May 13;133:155124. Epub 2020 May 13.

Department of Biochemistry, Faculty of Pharmacy, Cairo University, Cairo, Egypt. Electronic address:

Systemic sclerosis or systemic scleroderma (SSc) is an inflammatory autoimmune disease whose pathogenesis remains ambiguous; however, epigenetics, including long noncoding RNAs (lncRNAs) is an emerging paradigm. To date, the expression, role and clinical significance of most lncRNAs in SSc remain unelucidated. Herein, we investigated the plasma expression profiles of lncRNAs; ANCR, TINCR, HOTTIP, and SPRY4-IT1, which were linked to skin biology, in SSc patients and its subtypes, their potential as diagnostic tools and their correlations with autoantibodies and disease manifestations.

Superimposed mosaicism in tuberous sclerosis complex: a key to understanding all of the manifold manifestations?

Authors:
R Happle A Torrelo

J Eur Acad Dermatol Venereol 2020 May 12. Epub 2020 May 12.

Department. of Dermatology, Hospital Infantil Universitario Niño Jesús, Madrid, Spain.

In patients with tuberous sclerosis we can today distinguish between two different categories of segmental mosaicism. The well-known simple segmental mosaicism is characterized by a unilateral or otherwise localized arrangement of the ordinary lesions of the disorder, reflecting heterozygosity for an early postzygotic new mutation. By contrast, superimposed mosaicism is defined by a pronounced segmental involvement in a patient with ordinary nonsegmental lesions of the same disorder, resulting in a heterozygous embryo from loss of the corresponding wild-type allele that occurred at a very early developmental stage.

[Autologous hematopoietic stem cell transplantation for systemic sclerosis : Position statement of the stem cell therapy working party of the German Society of Rheumatology].

Z Rheumatol 2020 Apr 22. Epub 2020 Apr 22.

Medizinische Klinik m.S. Rheumatologie und Klinische Immunologie, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Charitéplatz 1, 10117, Berlin, Deutschland.

There have been three randomized controlled trials on autologous hematopoietic stem cell transplantation (AHSCT) in systemic sclerosis (SSc) that demonstrated significant superiority with respect to survival, improvement of cutaneous fibrosis, lung function and quality of life compared to standard treatment; however, these advantages must be carefully weighed against the transplantation-related risks. For this reason, an expert group from the stem cell therapy working party of the German Society for Rheumatology (DGRh) has now developed recommendations for the use of AHSCT in SSc. Based on the high-quality evidence, AHSCT is considered as the standard option for the treatment of selected SSc patients. Read More

Rotating frame MRI relaxations as markers of diffuse white matter abnormalities in multiple sclerosis.

Neuroimage Clin 2020 Mar 2;26:102234. Epub 2020 Mar 2.

Department of Radiology, Center for Magnetic Resonance Research (CMRR), University of Minnesota, Minneapolis, MN, USA. Electronic address:

Even though MRI visualization of white matter lesions is pivotal for the diagnosis and management of multiple sclerosis (MS), the issue of detecting diffuse brain tissue damage beyond the apparent T2-hyperintense lesions continues to spark considerable interest. Motivated by the notion that rotating frame MRI methods are sensitive to slow motional regimes critical for tissue characterization, here we utilized novel imaging protocols of rotating frame MRI on a clinical 3 Tesla platform, including adiabatic longitudinal, T1ρ, and transverse, T2ρ, relaxation methods, and Relaxation Along a Fictitious Field (RAFF) in the rotating frame of rank 4 (RAFF4), in 10 relapsing-remitting multiple sclerosis patients and 10 sex- and age-matched healthy controls. T1ρ, T2ρ and RAFF4 relaxograms extracted from the whole white matter exhibited a significant shift towards longer relaxation time constants in MS patients as compared to controls. Read More

1Department of Neurology, Laboratory of Neurogenetics, Faculty of Medicine, University of Thessaly, University Hospital of Larissa, Biopolis, Mezourlo Hill, 41100 Larissa, Greece.

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system characterized by focal or diffuse inflammation, demyelination, axonal loss and neurodegeneration. Brain atrophy can be seen in the earliest stages of MS, progresses faster compared to healthy adults, and is a reliable predictor of future physical and cognitive disability. In addition, it is widely accepted to be a valid, sensitive and reproducible measure of neurodegeneration in MS. Read More

Pathogenic Activation of Mesenchymal Stem Cells is induced by the Disease Microenvironment in Systemic Sclerosis.

Arthritis Rheumatol 2020 Mar 31. Epub 2020 Mar 31.

UCL Centre for Rheumatology and Connective Tissue Diseases, Royal Free Hospital Campus, University College London Medical School, Rowland Hill Street, London, NW3 2PF, UK.

Objective: In systemic sclerosis (SSc) a persistent tissue repair process leads to progressive fibrosis of the skin and internal organs. The role of mesenchymal stem cells (MSCs), which characteristically initiate and regulate tissue repair, has not been fully evaluated. We sought to investigate whether dividing metakaryotic MSCs are present in SSc skin, and test whether exposure to the disease microenvironment activates MSCs leading to transdifferentation.

Clinical significance of endothelial vasodilatory function evaluated by EndoPAT in patients with systemic sclerosis.

J Dermatol 2020 Mar 30. Epub 2020 Mar 30.

Department of Dermatology, University of Tokyo Graduate School of Medicine, Tokyo, Japan.

Endothelial dysfunction is a hallmark of vasculopathy associated with systemic sclerosis (SSc). Reactive hyperemia peripheral arterial tonometry is a rapid and non-invasive technique to assess peripheral microvascular endothelial function by measuring changes in digital pulse volume during reactive hyperemia. Low scores of the reactive hyperemia index (RHI) imply an impaired vasodilatory response and, accordingly, impaired endothelial and vascular health. Read More

Distribution of Cortical Diffusion Tensor Imaging Changes in Multiple Sclerosis.

Front Physiol 2020 13;11:116. Epub 2020 Mar 13.

Department of Neurology, Goethe University Frankfurt, Frankfurt, Germany.

Purpose: Diffuse cortical damage in relapsing-remitting multiple sclerosis (RRMS) is clinically relevant but cannot be directly assessed with conventional MRI. In this study, it was aimed to use diffusion tensor imaging (DTI) techniques with optimized intrinsic eddy current compensation to quantify and characterize cortical mean diffusivity (MD) and fractional anisotropy (FA) changes in RRMS and to analyze the distribution of these changes across the cortex.

Materials And Methods: Three-Tesla MRI acquisition, mapping of the MD providing information about the integrity of microstructural barriers and of the FA reflecting axonal density and surface-based analysis with Freesurfer were performed for 24 RRMS patients and 25 control subjects. Read More

Hypertension induces glomerulosclerosis in phospholipase C-ε1 deficiency.

Am J Physiol Renal Physiol 2020 May 30;318(5):F1177-F1187. Epub 2020 Mar 30.

Division of Nephrology, Department of Internal Medicine, University of Michigan, Ann Arbor, Michigan.

Loss-of-function mutations in phospholipase C-ε1 (PLCE1) have been detected in patients with nephrotic syndrome, but other family members with the same mutation were asymptomatic, suggesting additional stressor are required to cause the full phenotype. Consistent with these observations, we determined that global -deficient mice have histologically normal glomeruli and no albuminuria at baseline. Angiotensin II (ANG II) is known to induce glomerular damage in genetically susceptible individuals. Read More
