About

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

Full description

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

Enrollment: 21 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Adult (>18 years old) patient on HD > 6 months, and
• 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). The date of diagnosis was defined as the day when RT-PCR or CT-scan confirmed the diagnosis.

Exclusion criteria

• Inability to give consent
