Systemic inflammatory response syndrome after administration of unmodified T lymphocytes.

ABSTRACT: Systemic inflammatory response syndrome (SIRS) is a rare systemic inflammatory response associated with fever, tachycardia, profound hypotension, and respiratory distress, which has been reported in cancer patients receiving T cells genetically modified with chimeric antigen receptors to retarget their specificity to tumor-associated antigens. The syndrome usually occurs following significant in vivo expansion of the infused cells and has been associated with tumor destruction/lysis. Analysis of patient plasma has shown elevated cytokine levels, and resolution of symptoms has been reported after administration of steroids and/or antibodies (such as anti-tumor necrosis factor and anti-interleukin (IL)-6 receptor antibodies) that interfere with cytokine responses.To date, SIRS has not been reported in subjects receiving genetically unmodified T cells with native receptors directed against tumor antigens, in which greater physiological control of T-cell activation and expansion may occur. Here, however, we report a patient with bulky refractory Epstein-Barr virus (EBV)-associated lymphoma, who developed this syndrome 2 weeks after receiving T cells directed against EBV antigens through their native receptors. She was treated with steroids and etanercept, with rapid resolution of symptoms. SIRS may therefore occur even when T cells recognize antigens physiologically through their "wild-type" native receptors and should be acknowledged as a potential complication of this therapy.

Project description:Goal of the experiment: To identify correlated genes, pathways and groups of patients with systemic inflammatory response syndrome and septic shock that is indicative of biologically important processes active in these patients. Background: We measured gene expression levels and profiles of children with systemic inflammatory response syndrome (SIRS) and septic shock as a means for discovering patient sub-groups and gene signatures that are active in disease-affected individuals and potentially in patients with poor outcomes. Methods: Microarray and bioinformatics analyses of 123 microarray chips representing whole blood derived RNA from controls, children with SIRS, and children with septic shock. Results: A discovery-based filtering approach was undertaken to identify genes whose expression levels were altered in patients with SIRS or septic shock. Clustering of these genes identified 3 Major and several minor sub-groups of patients with SIRS or septic shock. The three groups differed with respect to incidence of septic shock and trended toward differences in mortality. Statistical analyses demonstrated that 6,435 gene probes were differentially regulated between the three patient sub-groups (false discovery rate < 0.001%). Of these gene probes, 623 gene probes within 7 major gene ontologies accounted for the majority of group differentiation. Network analyses of these 623 gene probes demonstrated 5 major gene networks that were differentially expressed between the 3 groups. Statistical comparison of septic shock survivors and non-survivors identified one major gene network that was under expressed in a high fraction of the non-survivors and identified potential biomarkers for poor outcome. Conclusions: This is the first genome-level demonstration of pediatric patient sub-groups with SIRS and septic shock. The sub-groups differ clinically and differentially express 5 major gene networks. We have identified gene signatures and potential biomarkers associated with poor outcome in children with septic shock. These data represent a major advancement in our genome-level understanding of pediatric SIRS and septic shock. Keywords: Septic shock, SIRS, pediatrics, outcome, infection, inflammation
