Morbimortality of Covid-19 in Patients With Chronic Inflammatory Rheumatism Treated With Immunosuppressants

Study Overview
=================
Brief Summary
-----------------
A retrospective monocentric study with large active files of patients monitored for rheumatoid arthritis, spondyloarthritis and systemic lupus erythematosus with as main endpoint the morbimortality of Covid-19 in these patients (number of patients hospitalized in conventional units and/or in intensive care and/or deceased). The results will be compared with those of the general population based on the epidemiological data of Covid-19.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| analysis of Covid-19-related morbidity and mortality in patients with IRC under IS. | the number of patients with severe Covid-19 who were admitted to a conventional unit and/or an ICU and/or deceased, during the Covid-19 epidemic wave (from March to August 2020) among patients with IRC under IS. The diagnosis of Covid-19 is either confirmed by diagnostic test (RT-PCR), or by a physician, or by serology. The results will be compared with those of the general population based on Covid-19 epidemiological data. | At 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate the frequency of Covid-19 in patients with IRC under IS. | Diagnosis of Covid-19 either confirmed by diagnostic test (RT-PCR), or by a physician, or by serology. | At 6 months | 
| To compare the morbidity and mortality of patients with IRC under IS during the Covid-19 epidemic wave (March to August 2020) with the six months prior to this wave (September 2019 to February 2020). | The number of patients admitted to conventional unit and/or ICU and/or deceased among patients with IRC under IS between the Covid-19 epidemic wave (March to August 2020) and the six-month period preceding it (September to February 2020). | At 6 months | 
| Patients' conduct in relation to their treatment during the epidemic wave (maintenance, modification or discontinuation) and the impact on their disease (loss of remission, flare, corticosteroids requirement and need for switch of DMARD therapy) | The number of patients who maintained, modified, or discontinued their treatment. Treatment modification will be assessed by the number of weeks of treatment not taken, the number of injections not given, the number of delayed or missed infusions. Among those who have modified or stopped their treatment, the impact on their diseases will be evaluated by the loss of remission, the patient's opinion on the notion of relapse, the increase or initiation of corticosteroid therapy and the substantive change in treatment. | At 6 months |
