Search for Diagnostic and Prognostic Biomarkers in Systemic Sclerosis and Inflammatory Myopathies (SCLEROMYOMICS)
Search for Diagnostic and Prognostic Biomarkers (Molecular Signatures) in Systemic Sclerosis and Inflammatory Myopathies by a Multi-OMIC Strategy Integrating a Single Cell Analysis Approach
調査の概要
詳細な説明
Cohort study, monocentric, comparative, non-randomized, open-label, prospective and longitudinal, quasi-experimental.
Participating subjects will be classified according to their clinical, biological and additional investigations into one of the 4 populations presented in the eligibility criteria.
A 1st sampling point will be carried out at inclusion visit (baseline). Prospective follow-up of participating patients will be carried out as part of their routine care (1 to 2 visits per year or more if disease complications appear).
During the 5-year follow-up, the investigating physician will remain attentive to the appearance of a new clinical element which will mark the course of the disease.
During the follow-up, 2 more sampling points will be carried out (blood and / or skin) on each participating patient.
Blood samples and muscle biopsies will be carried out in the usual way during diagnostic and therapeutic management. An additional volume of blood, an additional muscle biopsy (on the occasion of the one performed for diagnosis) and two superficial skin biopsies (1 sclerotic tissue & 1 healthy tissue) will be taken for research purposes.
Inclusion in this cohort will not change the management of the patient, either with regard to his treatment or his follow-up.
Multi-omics analyzes will include single cell RNAseq, as well as proteomics and genomics analysis:
- Transcriptomic analysis will be performed on PMBC, muscle and skin.
- Genomic analysis (exome & whole genome) will be performed on PMBC, muscle and skin.
- Proteomic analysis will be performed on serum, PMBC, muscle and skin.
- Single cell analysis will be performed on PMBC, muscle and skin. During the analysis, the clinical characteristics of baseline, the treatments and the evolutions during the follow-up will be compared to reveal the clinical relevance of the multi-OMIC signatures.

Evolution of the molecular profiles (i.e., genomic [New Generation Sequencing], transcriptomic [RNA chip], proteomic [mass spectrometry] and identification of cell population [single cell RNA sequencing]) of systemic sclerosis during 5 years.
時間枠：At Day 1
|
This study is descriptive (non-analytical), without prior hypothesis. Molecular profiles will be assessed by integration of multi-OMIC tools from a wide range of areas of biochemistry, chemistry, physics, computing science and molecular biology. During the 5-year follow-up, the investigating physician will remain attentive to the appearance of a new clinical element which will mark the course of the systemic sclerosis. |
