On the other hand, analytical data on disseminated intravascular coagulation, high levels of C-reactive protein and ferritin, and high levels of proinflammatory cytokines including interleukin 6 (IL-6), interferon gamma (IFN-γ), and tumor necrosis factor alpha (TNF-α) have been associated with severe ICANS.<a class="elsevierStyleCrossRefs" href="#bib0120"><span class="elsevierStyleSup">24,26,28</span></a> Overall, this data suggests the development of some sort of inflammatory syndrome with capillary leak after the infusion of CAR-T cells.</p><p id="par0050" class="elsevierStylePara elsevierViewall">From the pathophysiological point of view several factors triggering ICANS have been reported: the diffuse endothelial activation mediated by a high concentration of cytokines in peripheral blood (IL-6 and IFN-γ), which would also trigger disorders in the blood-brain barrier (BBB) confirmed by the detection of high levels of proteins and pleocytosis in the cerebrospinal fluid (CSF).<a class="elsevierStyleCrossRefs" href="#bib0120"><span class="elsevierStyleSup">24–26,29</span></a> In vitro studies have demonstrated that the pericytes of cerebral vascular endothelium are sensitive to the stimulation by proinflammatory cytokines, which would increase the patency of the BBB.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">26</span></a> Additionally, the local production of cytokines inside the CNS with significant increases of IL-8, IL-10, and the monocyte chemoattractant protein (MCP-1) in the CSF has been proposed as another mechanism associated with the appearance of severe ICANS.<a class="elsevierStyleCrossRefs" href="#bib0120"><span class="elsevierStyleSup">24,29</span></a> Santomasso et al.<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">24</span></a> reported that during the production of severe neurotoxicity, high levels of IL-1, and IL-6 in the CSF have been reported suggestive of hyperproduction inside the CNS.
