研究概览
简要总结
QuantiFERON Monitor® is an immunological test evaluating the nonspecific cellular response by measuring interferon gamma (IFNγ) secretions after T-cell and natural killer lymphocyte stimulation.
This study aims at evaluating sepsis-induced immunosuppression base on QuantiFERON Monitor® in patients presenting to the intensive care unit for septic shock. The sponsor expects to identify sepsis-induced immunodeficiency in patients through a better understanding of cellular and adaptive immune responses.
详细描述
A sepsis-induced immunosuppression phase has recently been characterized and has been associated with worse outcomes as well as increased healthcare costs. Furthermore, a marked suppression of the immune response has been partially described in patients hospitalized in the intensive care setting but its monitoring is not available in daily practice. QuantiFERON Monitor® is an immunological test evaluating the nonspecific cellular response by measuring interferon gamma (IFNγ) secretions after T-cell and natural killer lymphocyte stimulation. Several studies have shown the pertinence of this test, especially in patients with kidney failure requiring renal replacement therapy. Patients with lower IFNγ levels were also found to be at higher risk of infection.
This study aims at evaluating sepsis-induced immunosuppression base on QuantiFERON Monitor® in patients presenting to the intensive care unit for septic shock. The sponsor expects to identify sepsis-induced immunodeficiency in patients through a better understanding of cellular and adaptive immune responses. This should ultimately lead to determining thresholds for sepsis-related complications and identifying patients most at risk of sepsis-induced immuno-depression.
