This protocol seeks to assist biorepositories/biobanks in distributing their stored specimens and data to researchers that will actually utilize them to advance medicine and technology.

The coronavirus disease 2019 (COVID-19) pandemic is a potentially fatal disease that represents a great global public health concern. In European countries such as Spain, Italy, Germany, Portugal, England and France, the pandemic has been of utmost importance. To date, no treatment has been robustly validated, and two theoretically opposite therapeutic strategies are proposed, based either on antiretroviral therapy or on immunomodulating agents. In this complex context, people living with immune-mediated inflammatory diseases (IMID) raise specific concerns due to their potentially increased risk of infections or of severe infections. Among IMID, Sjögren's syndrome, systemic lupus erythematosus, rheumatoid arthritis, spondyloarthritis and giant cell arteritis are some key diseases. In this cross-sectional, observational, multi-centric study, the investigators aim to assess both clinical and serological prevalence of COVID-19 among samples of IMID patients in Europe. In parallel, the investigators aim to compare the prevalence of COVID-19 seroconversion across these five IMIDs, their penetration across different 6 European countries (France, Italy, Spain, Germany, United Kingdom and Portugal), and to assess the severity of COVID-19 in these patients. Moreover, changes in treatment will be assessed, including immunomodulatory tapering or discontinuation, its causes over the outbreak period, as well as the incidence of IMID flares and their severity over this same period. Finally, patient's perceptions towards the pandemic will be evaluated and compared to medication beliefs. Data will be collected through questionnaires during medical visit or phone consultation and serological tests will be performed within routine blood collection. As so, all study procedures are comprised within usual care. Through this study the investigators expect to have a better knowledge of the clinical and serological prevalence of COVID-19 in IMID across Europe, along with the psychological, clinical, and therapeutic impact of COVID-19 in this particular patient population.

Cardiac involvements in autoimmune diseases (AD) is common but underestimated and an early detection remains a clinical challenge for lacking of efficient imaging methods. The objective of the study was to investigate LV myocardial abnormalities in AD patients by multimodal cardiac imaging, including speckle-tracking echocardiology (STE), cardiac magnetic resonance imaging (CMRI) and positron emission tomography (PET).

Since December 2019, an international outbreak of respiratory illnesses caused by SARS-CoV-2 called covid-19 has become a global challenge. In France, while the first cases were reported in January, more than 20 000 cases were confirmed at end of March. Early estimations from epidemiological data seem to show that 18-20% of patients with confirmed covid-19 are admitted in an intensive care unit (ICU). Patients with chronic inflammatory rheumatism, auto-immune or auto-inflammatory rare and non-rare diseases are susceptible to severe covid-19 (i.e ICU) due to the specific therapeutic management of their illness (corticosteroid, immunosuppressive and immunomodulatory drugs,..). No data are available for this particular population in France. This retrospective multicentre observational study aims to evaluate the frequency of severe forms of covid-19 and risk factors associated with specific outcomes in covid-19 in patients with chronic inflammatory rheumatism, auto-immune or auto-inflammatory rare and non-rare diseases.

Autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, myositis, or anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, may affect multiple organ systems. Occasionally, patients deteriorate acutely requiring advanced care in an intensive care unit (ICU). In an ICU setting, mortality is estimated with scoring systems, such as APACHE or SAPSII. Since there are limited data available on their use in autoimmune diseases, with the current study, we aim to assess the usefulness of these ICU scores and analyze predictors of mortality in this particular group of patients.

Glial fibrillary acidic protein (GFAP)-Immunoglobulin G (IgG) have recently been described as a biomarker of a novel inflammatory central nervous system (CNS) disorder, termed autoimmune GFAP astrocytopathy. Thus far, four major clinical series have been published (two from Mayo Clinic USA, one from Italy and one from China). GFAP-IgG detected in serum or in cerebrospinal fluid, by tissue-based assay and confirmed by cell-based assay, are associated with encephalitis or meningoencephalitis of acute or subacute onset, less frequently with myelitis or optic disk edema. The characteristic MRI feature is brain linear perivascular radial gadolinium enhancement in the white matter perpendicular to the ventricle, consistent with the immunohistochemical staining pattern of GFAP in rodent brain sections. Approximately 20% of reported cases are associated with a neoplasm (ovarian teratoma mostly). Coexisting neural autoantibodies are described in some patients, N-methyl-D-aspartate (NMDA)-receptor (R)-IgG mostly, followed by aquaporin 4 (AQP4)-IgG. The disease is usually corticosteroid responsive although relapse can occur. In contrast, Chinese patients display poorer outcomes. Pathophysiology is not well understood but the intracellular antigen location makes GFAP-IgG unlikely pathogenic whereas animal models and neuropathologic data suggest a T-cell immune-mediated disorder. The aim of the investigators is to report the first French cohort of patients GFAP-IgG positive. Investigators retrospectively assessed clinical, immunological and radiological features, treatment response and outcomes.

Factors associated with severe forms of COVID-19 infection in patients with inflammatory rheumatic diseases (IRD) or Autoimmune Diseases (AID) are unknown. This unprecedented situation leads to empirical and potentially erroneous advice and recommendations for care. Identifying factors associated with severity, in the context of this pandemic, which is expected to last many months, and possibly years, is crucial for future patients. The objective of this work is to identify the factors associated with the occurrence of severe forms of COVID-19 infection in patients with IRD or AID, by combining analysis of 2 large databases.
