A machine learning application to predict early lung involvement in scleroderma: A feasibility evaluation
2021
Introduction: Systemic sclerosis (SSc) is a systemic immune-mediated disease, featuring fibrosis of the skin and organs, and has the greatest mortality among rheumatic diseases. The nervous system involvement has recently been demonstrated, although actual lung involvement is considered the leading cause of death in SSc and, therefore, should be diagnosed early. Pulmonary function tests are not sensitive enough to be used for screening purposes, thus they should be flanked by other clinical examinations
Manometrische untersuchungen zur oesophagusbeteiligung bei progressiver sklerodermie
1975
Bei 15 Patienten mit progressiver Sklerodermie wurde die Oesophagus funktion manometrisch und radiologisch untersucht. Nur ein Drittel der Patienten gab Schluckbeschwerden an. Dagegen liesen sich radiologisch bei 8 Patienten (55%) deutliche Motilitatsstorungen nachweisen, mit der Oesophagusmanometrie sogar bei 11 Patienten (73%). Fehlende subjektive Symptome schliesen demnach einen ausgedehnten Befall der Speiserohre nicht aus. Die manometrischen Messungen zeigen, das mit einer Beteiligung der Speiserohre im odematos-indurativen Stadium der Sklerodermie in einem wesentlichen hoheren Prozentsatz gerechnet werden mus, als ublicherweise aufgrund von Rontgenuntersuchungen allein angenommen wurd…
The systemic lupus erythematosus IRF5 risk haplotype is associated with systemic sclerosis.
2013
Systemic sclerosis (SSc) is a fibrotic autoimmune disease in which the genetic component plays an important role. One of the strongest SSc association signals outside the human leukocyte antigen (HLA) region corresponds to interferon (IFN) regulatory factor 5 (IRF5), a major regulator of the type I IFN pathway. In this study we aimed to evaluate whether three different haplotypic blocks within this locus, which have been shown to alter the protein function influencing systemic lupus erythematosus (SLE) susceptibility, are involved in SSc susceptibility and clinical phenotypes. For that purpose, we genotyped one representative single-nucleotide polymorphism (SNP) of each block (rs10488631, r…
Vitamin D increases the production of IL-10 by regulatory T cells in patients with systemic sclerosis
2019
OBJECTIVES: Vitamin D status influences the risk to develop autoimmune diseases affecting the percentage and/or functions of regulatory T cells (Tregs). Since low levels of 25 (OH) D have been decreased in patients with systemic sclerosis (SSc), we aimed to study the effect of Vitamin D3 (cholecalciferol) supplementation on Tregs frequencies and functions. METHODS: Peripheral blood and sera samples were obtained from 45 SSc patients and controls (HC). A number of eighteen SSc patients had consumed Cholecalciferol (orally) at the dose of 25.000 UI/month for 6 months at the time of enrollment. 25(OH)D serum levels were measured and VDR polymorphisms, were genotyped by polymerase chain reactio…
Polymorphism of immunoglobulin enhancer element HS1,2A: allele *2 associates with systemic sclerosis. Comparison with HLA‐DR and DQ allele frequency
2007
OBJECTIVE: To investigate the relationship of the polymorphic enhancer HS1,2 central to the 3' enhancer complex regulatory region (IgH3'EC) of the immunoglobulin heavy chain genes with systemic sclerosis (SSc) disease and compare it with HLA-DR and DQ associations. METHODS: A total of 116 patients with SSc were classified as diffuse (dSSc) or limited (lSSc), and as carriers of antitopoisomerase I (anti-Scl70) or anticentromere (ACA) antibodies. Allele and genotype frequencies were assessed in the population as a whole and in the two major subsets, dSSc and lSSc. The concentration of peripheral blood immunoglobulin levels was also determined and analysed according to the genotypes. RESULTS: …
Confirmation of TNIP1 but not RHOB and PSORS1C1 as systemic sclerosis risk factors in a large independent replication study
2012
Item does not contain fulltext INTRODUCTION: A recent genome-wide association study in European systemic sclerosis (SSc) patients identified three loci (PSORS1C1, TNIP1 and RHOB) as novel genetic risk factors for the disease. The aim of this study was to replicate the previously mentioned findings in a large multicentre independent SSc cohort of Caucasian ancestry. METHODS: 4389 SSc patients and 7611 healthy controls from different European countries and the USA were included in the study. Six single nucleotide polymorphisms (SNP): rs342070, rs13021401 (RHOB), rs2233287, rs4958881, rs3792783 (TNIP1) and rs3130573 (PSORS1C1) were analysed. Overall significance was calculated by pooled analys…
Rehabilitative interventions for ischaemic digital ulcers, pain, and hand functioning in systemic sclerosis: a prospective before-after study
2022
Abstract Background Systemic sclerosis (SSc) is a rare connective tissue disease characterised by immune dysfunction, vasculopathy, cellular inflammation, fibrosis of the skin associated with multiple internal organs involvement. Ischaemic digital ulcers (IDU) of the hands commonly occur in patients with SSc adversely affecting functional independence. Purpose Aim of the study is to investigate the effectiveness of a rehabilitation protocol based on the combined use of ultrasound (US) therapy and therapeutic exercise in terms of ulcers healing, pain relief, and hand functioning in patients affected by SSc with IDUs. Moreover, we also investigated the safety of the proposed intervention. Stu…
IL-13 and IL-33 Serum Levels Are Increased in Systemic Sclerosis Patients With Interstitial Lung Disease
2022
ObjectiveSystemic sclerosis (SSc) mortality is extremely variable in its internal organ involvement. Pulmonary fibrosis occurs in up to 30% of the cases. Animal models provide evidence that IL-33 is able to induce both cutaneous and pulmonary fibrosis via increased IL-13 and in SSc patients the levels of IL-33 correlate with skin fibrosis. Our aim was to test whether both IL-33 and IL-13 are higher in patients with diffuse SSc and interstitial lung disease (SSc-ILD) compared to SSc patients without ILD and healthy controls.MethodsSerum levels of IL-13 and IL-33 were measured in 30 SSc patients with diffuse disease and 30 healthy controls by enzyme-linked immunosorbent assay. The extent of p…
Interleukin-32 in systemic sclerosis, a potential new biomarker for pulmonary arterial hypertension
2020
Abstract Background Pulmonary arterial hypertension (PAH) is a severe complication of systemic sclerosis (SSc), associated with a progressive elevation in pulmonary vascular resistance and subsequent right heart failure and death. Due to unspecific symptoms, the diagnosis of PAH is often delayed. On this basis, it is of great value to improve current diagnostic methods and develop new strategies for evaluating patients with suspected PAH. Interleukin-32 (IL-32) is a proinflammatory cytokine expressed in damaged vascular cells, and the present study aimed to assess if this cytokine could be a new biomarker of PAH during SSc. Methods The IL-32 expression was evaluated in the sera and skin sam…
