Inclusion criteria were (1) Adult (>18 years old) patient on HD > 6 months, and (2) infection by SARS-CoV-2. Diagnosis of COVID-19 was assessed by Reverse-Transcriptase-Polymerase Chain Reaction (RT-PCR) for SARS-CoV-2 in nasopharyngeal swab or by typical COVID-19 radiological images on thoracic computerized tomography (CT scan).~Severe forms of COVID-19 were defined as requiring oxygen therapy, admission in intensive care unit (ICU) or death~Primary end point :~* Characterization the cytokine's profile at the early (day 7) and inflammatory (day 14) phase of COViD-19 in HD patient~Secondary End points :~Analyse the kinetic of the antiviral response (type I and III interferon ) between the early (day 7) and inflammatory (day 14) phase of COViD-19.~Analyse the kinetic of proinflammatory cytokine response between the early (day 7) and inflammatory (day 14) phase of COViD-19.~Define an antiviral signature associated with severe form of COVID-19~Define an anti inflammatory signature associated with severe form of COVID-19~Cytokine's profile is define by the measure of 28 cytokines by Luminex technology
Patients with chronic kidney disease (CKD), particularly those undergoing hemodialysis (HD), are at high risk of a severe form of COVID-19.~This study aims to characterize the inflammatory and antiviral response during SarsCov2 infection in adult
