Search for Diagnostic and Prognostic Biomarkers in Systemic Sclerosis and Inflammatory Myopathies...
Systemic SclerosisInflammatory MyopathiesSystemic sclerosis and inflammatory myopathies, which sometimes combine (scleromyositis), have shared pathophysiological elements. In both diseases, many cell subtypes are involved in damage to organs such as T lymphocytes, B lymphocytes, and unconventional (non-B, non-T) lymphocytes called innate lymphoid cell (ILC). The increasing complexity of our understanding of the immune system (multiplication of recognized cell subtypes) also makes the strategies for analyzing pathophysiological mechanisms more complex. Currently, no biomarker perfectly predicts the phenotype and evolution of patients. Multi-OMIC analyzes will be performed (identification of cell populations as well as genomic, transcriptomic and proteomic characterization) in blood and tissue samples (skin and muscle biopsy) in patients with systemic sclerosis and inflammatory myopathies, with the objective of identifying discriminating molecular signatures (biomarkers) according to the characteristics of the disease and its evolution.
AR-Power Patient Powered Research Network
Rheumatoid ArthritisAnkylosing Spondylitis11 moreArthritisPower is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), and other musculoskeletal conditions. Participants will provide information from their smartphones or personal computers. The information will be used by researchers to help patients and their providers make better, more informed decisions about treatment of RA/SpA and other musculoskeletal conditions. ArthritisPower is part of a larger national research network called PCORnet whose 33 network members have mapped their data to a common data model. Network members will be able to submit queries through PCORnet in order to answer a range of comparative effectiveness research questions. Data sharing across PCORnet will be accomplished using secure methods to prevent patient identification. There is no cost to participants for participating and no compensation is provided. Objectives: To establish a research registry to enable comparative effectiveness research in rheumatic diseases and other musculoskeletal conditions. All data collected using the ArthritisPower mobile app as part of a subject's use is stored with the ArthritisPower registry. This data will be used in conjunction with existing and future research studies. To use the data from this study to improve treatment and to further advance finding a cure for rheumatic diseases.
Pompe & Pain - Study to Assess Nociceptive Pain in Adult Patients With Pompe Disease
Pompe Disease (Late-onset)Inclusion Body Myositis2 moreThe primary aim of this nationwide, explorative, cross-sectional study in Germany is to characterize the prevalence, severity and quality of musculoskeletal pain in adult patients with late-onset Pompe disease (LOPD). The secondary objectives are to evaluate whether muscle pain is associated with muscle function, to assess whether muscle pain is associated with alterations of muscle tissue, and whether vitamin D metabolism and polymorphisms of ACE and ACTN3 genes may contribute to an increased level of perceived musculoskeletal pain. In a second step, exome sequencing of genes associated with musculoskeletal pain will be analyzed. Results of LOPD patients will be compared to patients with neuromuscular disorders with a similar distribution of muscle weakness and/or musculoskeletal pain.
ILD-SARDs Registry and Biorepository
Interstitial Lung DiseaseSystemic Autoimmune Disease7 moreA complex interaction between demographic, environmental and genetic mechanisms impact the onset, severity and outcome of ILD-SARDs through dysregulation of the immune system and lung pro-biotic pathways. Comorbidity and genetic risk indicate that there are overlapping pathogenic mechanisms among SARDs, some of which underlie ILD in different SARDs. The purpose of this biobank is to study the clinical, pathological, laboratory, and imaging characteristics of SARDs patients with lung involvement. This will help identify as unique features underlying lung involvement in SARDs. In addition, this may lead to the discovery of novel mechanisms of disease and potentially novel targets of treatment for SARDs patients with lung disease.
Sporadic Inclusion Body Myositis Natural History Study
Sporadic Inclusion Body MyositisInclusion Body MyositisThis is a prospective natural history study on patients with clinically defined sIBM. Participants will be assessed every 6 months over two years (five visits total). We will include 150 participants, enrolled across 13 sites, with sporadic IBM, diagnosed according to established criteria.
Optimizing Treatment on Idiopathic Inflammatory Myopathies
Idiopathic Inflammatory MyopathiesAs a T2T, our patients with idiopathic inflammatory myopathies will receive pulse therapies with methyprednisolone and/or human intravenous immunoglobulin, or only methyprednisolone at disease onset. This scheme is an internal routine protocol of our Service.
Pregnancy and Medically Assisted Conception in Rare Diseases
Rheumatoid ArthritisSpondyloarthritis9 moreRare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care. Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child. For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.
Inclusion Body Myositis Treatment With Celution Processed Adipose Derived Regenerative Cells
Inclusion Body MyositisThis is an open-label, single arm study evaluating the safety for patients with Inclusion Body Myositis. A total of 9 subjects will be enrolled in the study. Subjects will be randomized to Part 1 or Part 2 of the study in blocks of 3 every 3 months. Stem cell injections will be given in the forearm and thigh on either the left or right side of the body, depending on which side meets criteria. The overall goal of this pilot study is to test the safety of adipose derived regenerative cells in patients with Inclusion Body Myositis. If determined safe, this trial could lead to larger Phase II trials. While this specific trial's primary endpoint is safety, it our ultimate hope that ADRC injections into the forearm and thigh of IBM patients will slow, stabilize, or even reverse the progression of muscle weakness in patients with IBM.
The Risk of Falls Index for Patients With Neuromuscular Disorders
Inclusion Body MyositisMyotonic Dystrophy4 moreThe combination of short quantitatively assessing muscular function and balance in combination with short clinical scores, can be a new valid approach to evaluate the patient risk of fall and help to create a quick checkup test to prescribe an appropriate assistive device. The primary goal of this project is to provide a short battery of clinical assessments used to determine risk of falling for patients with neuromuscular diseases (NMD) based on correlation between clinical assessments between two groups of NMD patients and scales used to assess risk of falling for patients.
PRediction Of DIverse Glucocorticoids toxIcity OUtcomeS
Inflammatory RheumatismPolymyalgia Rheumatica4 moreTo date, there is no available tool that allows, at individual level, determination of the probability to develop clinically relevant complications of prolonged glucocorticoid therapy. In patients with inflammatory rheumatic disorders requiring prolonged glucocorticoid therapy, such tool could be useful to adapt first-line treatment decisions (in daily practice and in future clinical trials). The main objective of the study is to identify routine clinical, biological and DXA baseline characteristics predictive of the occurrence of clinically relevant complications of glucocorticoid therapy at 1 year, in order to propose a predictive score.
