There is one clinical trial.
The new Severe acute respiratory syndrome coronavirus (SARS-CoV-2) named coronavirus disease 2019 (COVID-19) is currently responsible for a pandemic spread of febrile respiratory infections, responsible for a veritable global health crisis. In adults, several evolutionary patterns are observed: i) a/pauci-symptomatic forms; ii) severe forms immediately linked to rare extensive viral pneumonia; and iii) forms of moderate severity, some of which progress to secondary aggravation (Day 7-Day 10). Children can be affected, but are more rarely symptomatic and severe pediatric forms are exceptional. Like some other coronaviruses (SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV)), these differences in clinical expression could be based on a variability in the immunological response, notably either via inhibition of the type I interferon (IFN-I) response, or on the contrary an immunological dysregulation responsible for a "cytokine storm" associated with the aggravation. Little is known about the impact of these innate immune response abnormalities on the adaptive response. In addition, certain genetic factors predisposing to a state of "hyper-fragility" and certain viral virulence factors could also be predictive of the clinical response. In this context, the main hypothesis is that the virological analysis and the initial biological and immunological profiles are correlated with the initial clinical presentation of COVID-19 infection. In particular, children forms and pauci-symptomatic disease in adults may be linked to a more robust innate immune response, including better production of IFN-I.
Description: Describe the immune response (biological profile in blood samples) of children and adults with COVID-19 infection and correlate it with the initial clinical presentation measurement of the following parameters in blood at time of inclusion: white blood cell count, C-reactive protein, procalcitonin, hepatic and renal functions, ferritin, vitamin C and D, fibrinogen, prothrombin time test and partial thromboplastin time in order to correlate them with the initial clinical presentation.
Measure: Initial biological profile of children and adults with COVID-19 infection Time: Day 0Description: measurement of the following parameters in blood at time of inclusion: interferon alpha and gamma, Tumor necrosis factor (TNF) alpha, interleukins 6 and 10, transcriptomic signature of interferon, lymphocyte phenotyping and monocyte Human Leukocyte Antigen - DR isotype (HLA-DR) expression in order to correlate them with the initial clinical presentation.
Measure: Initial immunological profile of children and adults with COVID-19 infection Time: Day 0Description: Determine whether the initial biological and immunological profiles (see primary outcome measures) are predictive of a secondary worsening (i.e., admission to intensive care unit, and/or increase in NEWS-2 score, and/or increase in oxygen dependence level) of COVID-19 infection
Measure: Clinical worsening Time: Within 21 days following inclusionDescription: measurement of the following parameters in blood at day 7, and at time of worsening: interferon alpha and gamma, TNF alpha, interleukins 6 and 10, transcriptomic signature of interferon, lymphocyte phenotyping and monocyte HLA-DR expression in order to correlate them with with the secondary worsening
