AbstractCytokine release syndrome (CRS) embodies a mixture of clinical manifestations, including elevated circulating cytokine levels, acute systemic inflammatory symptoms and secondary organ dysfunction, which was first described in the context of acute graft-versus-host disease after allogeneic hematopoietic stem-cell transplantation and was later observed in pandemics of influenza, SARS-CoV and COVID-19, immunotherapy of tumor, after chimeric antigen receptor T (CAR-T) therapy, and in monogenic disorders and autoimmune diseases. Particularly, severe CRS is a very significant and life-threatening complication, which is clinically characterized by persistent high fever, hyperinflammation, and severe organ dysfunction. However, CRS is a double-edged sword, which may be both helpful in controlling tumors/viruses/infections and harmful to the host. Although a high incidence and high levels of cytokines are features of CRS, the detailed kinetics and specific mechanisms of CRS in human diseases and intervention therapy remain unclear. In the present review, we have summarized the most recent advances related to the clinical features and management of CRS as well as cutting-edge technologies to elucidate the mechanisms of CRS. Considering that CRS is the major adverse event in human diseases and intervention therapy, our review delineates the characteristics, kinetics, signaling pathways, and potential mechanisms of CRS, which shows its clinical relevance for achieving both favorable efficacy and low toxicity.

Abstract As immune-based therapies for cancer become potent, more effective, and more widely available, optimal management of their unique toxicities becomes increasingly important. Cytokine release syndrome (CRS) is a potentially life-threatening toxicity that has been observed following administration of natural and bispecific antibodies and, more recently, following adoptive T-cell therapies for cancer. CRS is associated with elevated circulating levels of several cytokines including interleukin (IL)-6 and interferon γ, and uncontrolled studies demonstrate that immunosuppression using tocilizumab, an anti-IL-6 receptor antibody, with or without corticosteroids, can reverse the syndrome. However, because early and aggressive immunosuppression could limit the efficacy of the immunotherapy, current approaches seek to limit administration of immunosuppressive therapy to patients at risk for life-threatening consequences of the syndrome. This report presents a novel system to grade the severity of CRS in individual patients and a treatment algorithm for management of CRS based on severity. The goal of our approach is to maximize the chance for therapeutic benefit from the immunotherapy while minimizing the risk for life threatening complications of CRS.

AbstractInflammatory responses rapidly detect pathogen invasion and mount a regulated reaction. However, dysregulated anti-pathogen immune responses can provoke life-threatening inflammatory pathologies collectively known as cytokine release syndrome (CRS), exemplified by key clinical phenotypes unearthed during the SARS-CoV-2 pandemic. The underlying pathophysiology of CRS remains elusive. We found that FLIP, a protein that controls caspase-8 death pathways, was highly expressed in myeloid cells of COVID-19 lungs. FLIP controlled CRS by fueling a STAT3-dependent inflammatory program. Indeed, constitutive expression of a viral FLIP homolog in myeloid cells triggered a STAT3-linked, progressive, and fatal inflammatory syndrome in mice, characterized by elevated cytokine output, lymphopenia, lung injury, and multiple organ dysfunctions that mimicked human CRS. As STAT3-targeting approaches relieved inflammation, immune disorders, and organ failures in these mice, targeted intervention towards this pathway could suppress the lethal CRS inflammatory state.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder that occurs in many underlying conditions in all age. This is characterized by unbridled activation of cytotoxic T lymphocytes, natural killer (NK) cells and macrophages resulting in raised cytokine level. Those cytokines and immune mediated injury occur in multiple organ systems. It may be primary and secondary. Primary HLH is familial, childhood presentation and associated with gene mutations. Secondary HLH is acquired, adulthood presentation that occurs in infections, malignancies inflammatory and autoimmune diseases etc. Clinical manifestations include fever, splenomegaly, lymphadenopathy, neurologic dysfunction, coagulopathy, features of sepsis etc. Laboratory investigation includes cytopenias, hypertriglyceridemia, hyperferritinemia, abnormal liver function, hemophagocytosis, and diminished NKcell activity. Treatment modalities include immunosuppressive, immunomodulatory agents, cytostatic drugs, T-cell antibodies, anticytokine agents and hematopoietic stem cell transplantation (HSCT). Besides those, aggressive supportive care combined with specific treatment of the precipitating factor can produce better outcome. With treatment more than 50% of children who undergo transplant survive, but adults have quite poor outcomes even with aggressive management. Faridpur Med. Coll. J. 2020;15(2): 98-102

Introduction Cytokine release syndrome (CRS) is a common and potentially severe toxicity associated with haploidentical peripheral blood hematopoietic stem cell transplantation (Haplo-HSCT). CRS is characterized by immune activation and a high level of circulating inflammatory cytokines, particularly interleukin-6 (IL-6). While tocilizumab, an IL-6 receptor-targeted monoclonal antibody has been effectively used to treat CRS in the context of immunotherapy, it has not been evaluated during the acute Haplo-HSCT period. We hypothesized that prophylactic tocilizumab can prevent CRS after Haplo-HSCT. We report the results of a pilot trial to evaluate its use. Methods Patients ≥18 years undergoing Haplo-HSCT of peripheral blood in a single center with any underlying diagnosis were included. The conditioning was myeloablative and was administered as follows: cyclophosphamide 350 mg / m2 and fludarabine 25 mg / m2 (days -5-3) or rabbit antithymocyte globulin (2.5 mg / kg days -4, -3), plus melphalan 200 mg / m2 PO (days -2-1). Prophylaxis of graft versus host disease (GVHD) consisted of cyclophosphamide (50 mg / kg / day, days +3 and +4), cyclosporine and mycophenolate mofetil on day +5. The cells were infused on day 0. Tocilizumab was administered on day -1 in a single dose of 4 mg / kg IV. CRS was rated according to Lee et al. The primary outcome included the incidence and severity of CRS, the adverse effects associated with tocilizumab, hospitalization and graft rates and the incidence of GVHD. Results Ten patients have enrolled, with an average age of 26 years (range 19-32). The underlying diagnoses were acute lymphoblastic leukemia (n = 7), acute myeloid leukemia (n = 1) and non-Hodgkin lymphoma (n = 2). There were no infusion reactions associated with tocilizumab. Six patients (60%) developed CRS, all grades 1-2, with a median day of onset on day +2 (range 1-3) and a median fever duration of 2 days (range 2-3), often accompanied by nausea, diarrhea, dehydration and transaminitis. All patients were hospitalized; hospitalization was not related to CRS in three patients. 4 patients are alive without relapse (40%), 2 patients alive with relapse (20%), 3 patients died due to transplant-related mortality (30%), one patient dies from relapse (10%). No graft failure occurred and mixed chimerism was observed in a patient. Acute GVHD with steroid response has been diagnosed in 2 cases (20%, grade I / II). The median follow-up is 8.3 months (range 0-20). Conclusion What we observe about the prophylactic use of tocilizumab for Haplo-HSCT of peripheral blood is that its administration is feasible, Grades 1-2 CRS was observed in 60% of patients, grades 3-4 were not observed, however the use of tocilizumab did not prevent hospitalizations. More feasibility data is required before starting a definitive randomized trial to evaluate the use of tocilizumab for Haplo-HSCT peripheral blood.

Sepsis is a life-threatening organ dysfunction caused by dysregulated host response to infections. It is a leading cause of morbidity and mortality in hospitalized patients. Patients with sepsis often require care in the intensive care unit (ICU) which is costly to the patients and their families. Sepsis has no specific clinical manifestations, and its pathophysiological mechanism is complex. The disease progresses rapidly which makes early diagnosis difficult. Severe forms of the disease, such as septic shock, may lead to organ dysfunction, organ failure, and death. As an emerging “-omics” technology, metabolomics has revolutionized the clinical and research landscape of sepsis. Metabolomics has been applied in the prognosis, diagnosis, and risk stratification in patients with sepsis. This technology provides details on the metabolites and biochemical pathways commonly associated with the pathophysiology of sepsis. At present, it is mostly used to identify metabolites in various diseases. Using this technology, metabolites in body fluids such as blood and urine are detected and analyzed in relation to disease progresssion. The technology therefore helps to understand the pathogenesis of diseases and promote early diagnosis and treatment of the disease. So far, the applicaition of metabolomics in patients with sepsis has not been well defined. This article briefly reviews the application of metabolomics technology in patients with sepsis in recent years, to generate ideas for improving rapid diagnosis and prognosis evaluation of patients with sepsis.

Abstract CTL019 are autologous T cells genetically modified to express a chimeric antigen receptor (CAR) consisting of an external anti-CD19 domain with the CD3z and 4-1BB signaling domains, and mediate potent anti-tumor effects in patients (pts) with advanced, R/R CLL, ALL and NHL. CRS is the most serious toxicity of CTL019 therapy; symptoms can include fevers, nausea, myalgias, capillary leak, hypoxia, and hypotension. Standard CRS grading criteria are not applicable to CAR T cell therapies. To better capture clinical manifestations of CRS and guide intervention after CTL019, we devised a novel CRS grading scale. that was applied to 40 pts treated with CTL019 for R/R CLL; 14 pts on an initial pilot and 26 pts on an ongoing dose-optimization trial (reported separately). Our new CRS grading system is shown below. Pts were 80% male, a median age of 65 (range 51-78) and received a median of 4 prior therapies (range 1-10). 41% had known mutation at p53. 83% of 24 pts tested had unmutated IgVH. Response rate to CTL019 (CR+PR) was 42%. CRS was the major toxicity and occurred in 57% (23/40) of pts. CRS was gr 1 in 10%, gr 2 in 17%, gr 3 in 15% and gr 4 in 15%. Development of CRS correlated with response; 13/23 (57%) pts with CRS responded versus 4/17 (24%) pts without CRS responded (p=0.05). CRS was associated with elevations in IL-6, IFN-g, and other cytokines; details for 33 pts will be presented. Peak fold-increase over baseline for IL-6 was a median of 10.6x (range 0.28–649) and for IFN- g a median of 32.9x (1–7243x). For pts with CRS, this increase in IL-6 was a median of 23.5x compared to 1.86x in pts without CRS (p=0.001); and in IFN- g was a median of 97.2xin pts with CRS compared to 24.2x without (p=0.018). Increasing CRS severity was associated with peak fold change in IL-6 (p< 0.0001) and IFN- g (p=0.015). Notably, unlike cytokine changes associated with sepsis, TNF-a did not markedly increase during CRS. CRS occurred with a consistent and often dramatic increase in ferritin, C reactive protein (CRP), and hemophagocytosis, suggesting concurrent macrophage activation syndrome (MAS). Increasing CRS severity was associated with an increasing trend for peak ferritin (log scale, p<0.001) and peak CRP (p<0.001). The median peak ferritin was 13,463 ng/ml in pts with CRS compared to 378 in pts without (p<0.001). Median peak CRP was 16 mg/dl in pts with CRS compared to 3.86 in pts without (p=0.002). CRS required intervention in 8 pts. 1 pt was successfully treated with corticosteroids. Given marked increases in IL-6, 7 patients received the IL6-receptor antagonist tocilizumab with or without corticosteroids with resolution of CRS. Tocilizumab was given to 1/7 pts with gr 2 CRS, 1/6 pts with gr 3 and 5/6 pts with gr 4. Several pts also received corticosteroids and/or etanercept. All pts had resolution of CRS signs with no TRM from CRS. CRS is the most significant complication of CTL019 and can be life threatening. A novel CRS grading system was needed to identify CRS severity more accurately guide intervention timing. CTL019-related CRS is associated with a unique cytokine profile and has been manageable with anti-cytokine therapy in pts with R/R CLL. CRS appears to correlate with response of CLL to CTL019. Further study is needed to develop reliable methods to predict severity and minimize CRS toxicity without inhibiting anti-leukemia activity of CTL019. New CRS Grading System for CTL019 Abstract 1983. Table Grade 1 Grade 2 Grade 3 Grade 4 Mild: Treated with supportive care such as anti-pyretics, anti-emetics Moderate: Requiring IV therapies or parenteral nutrition; some signs of organ dysfunction (i.e. gr 2 Cr or gr 3 LFTs) related to CRS and not attributable to any other condition. Hospitalization for management of CRS related symptoms including fevers with associated neutropenia. More severe: Hospitalization required for management of symptoms related to organ dysfunction including gr 4 LFTs or gr 3 Cr related to CRS and not attributable to any other conditions; this excludes management of fever or myalgias. Includes hypotension treated with IV fluids or low-dose pressors, coagulopathy requiring FFP or cryoprecipitate, and hypoxia requiring supplemental O2 (nasal cannula oxygen, high flow 02, CPAP or BiPAP). Pts admitted for management of suspected infection due to fevers and/or neutropenia may have gr 2 CRS. Life-threatening complications such as hypotension requiring “high dose pressors”, hypoxia requiring mechanical ventilation.
