About this study

Official title: Evaluation of Interleukine 6 (and Other Cytokines and Inflammatory Markers) in SARS-Cov-2 Infected Patients With a Systemic Inflammatory Response Syndrome

In patients infected by the SARS-Cov-2 Coronavirus a severely progressive disease requiring hospitalization in intensive care seems related to deregulation of cytokines with very high levels of IL-6, IL-2, IL-7, IL-10 and TNF-α. In order to elucidate the mechanism of this hyper inflammatory syndrome we will measure a panel of pro and anti inflammatory cytokines, as well as known markers of macrophage activation syndrome.

To determine the role of activation of the complement cascade the most important complement factors and their activation markers will be measured.

The changes of those parameters will be monitored after administration of an anti-IL6R antibody therapy.

Read the detailed description

In patients with severely progressive SARS-Cov-2 Coronavirus infection, the elderly and immunocompromised are at greater risk of progressing to a serious image of ARDS (Acute Respiratory Distress syndrome). A recent study has shown that patients, sometimes young, requiring hospitalization in intensive care have deregulation of cytokines with very high levels of IL-6, IL-2, IL-7, IL-10 and TNF-α. The cytokines involved in the pathogenesis and clinical manifestations of CRS are mainly IL-6, gamma interferon (IFN-g), tumor necrosis factor alpha (TNF-a) and IL-10.

Although immunoinflammatory therapy is not systematically recommended in pneumonia linked to SARS-CoV-2, given the CRS and the pathophysiological results of pulmonary edema and the formation of the hyaline membrane, a targeted therapeutic approach and temporally accompanied by adequate ventilatory support could be beneficial in patients with severe pneumonia who develop ARDS. Tocilizumab (Roactemra®) is a drug that blocks the IL-6 receptor commonly prescribed for the treatment of rheumatoid arthritis. The intravenous formulation has been approved for the treatment of CRS which occurs during treatment with Car-T; given the clinical picture and cytokine levels in patients with severe SARS-Cov-2 pneumonia, Tocilizumab or another anti-IL6R antagonist may reasonably be expected to contribute to the control of virus-induced Systemic Inflammatory Response Syndrome (SIRS) in patients with elevated levels of IL-6.

The objectivation of high interleukin 6 levels in these patients should be an important scientific argument to justify the administration of therapy based on antagonization of IL6. Measurement of other pro inflammatory cytokines will shed light on the mechanism of the inflammatory syndrome induced by the SARS-CoV-2 virus.

One of the pathophysiological mechanisms of pulmonary pathology could be the induction of the production of complement factors by interleukin 6 as well as the activation of the complement cascade by the virus via the lectin pathway. It is known that one of the effects of Tocilizumab is to reduce the concentration of the various complement factors, the synthesis of which is under the control of interleukin 6. This is why this study proposes to measure certain parameters of the complement (CH50, C3, C4, C3d, C5a, SC5b-9, C4a, MASP-2) in order to objectify and quantify this activation.

If the activation of the complement proves significant it could be an argument for a treatment targeting more specifically the cascade of the complement.
