Identification of Predictive Biomarkers for Cytokine Release Syndrome after Chimeric Antigen Receptor T cell Therapy for Acute Lymphoblastic Leukemia

Abstract: Chimeric antigen receptor (CAR)-modified T cells with anti-CD19 specificity are a highly effective novel immune therapy for relapsed/refractory acute lymphoblastic leukemia (ALL). Cytokine release syndrome (CRS) is the most significant and life-threatening toxicity. To improve understanding of CRS, we measured cytokines and clinical biomarkers in 51 CTL019-treated patients. Peak levels of 24 cytokines, including IFNγ, IL6, sgp130, and sIL6R in the first month after infusion were highly associated with severe CRS. Using regression modeling, we could accurately predict which patients would develop severe CRS with a signature composed of three cytokines. Results validated in an independent cohort. Changes in serum biochemical markers, including C-reactive protein and ferritin, were associated with CRS but failed to predict development of severe CRS. These comprehensive profiling data provide novel insights into CRS biology, and importantly represent the first data that can accurately predict which patients have a high probability of becoming critically ill.

Hyperbilirubinemia in the term newborn.

Abstract: Hyperbilirubinemia is one of the most common problems encountered in term newborns. Historically, management guidelines were derived from studies on bilirubin toxicity in infants with hemolytic disease. More recent recommendations support the use of less intensive therapy in healthy term newborns with jaundice. Phototherapy should be instituted when the total serum bilirubin level is at or above 15 mg per dL (257 micromol per L) in infants 25 to 48 hours old, 18 mg per dL (308 micromol per L) in infants 49 to 72 hours old, and 20 mg per dL (342 micromol per L) in infants older than 72 hours. Few term newborns with hyperbilirubinemia have serious underlying pathology. Jaundice is considered pathologic if it presents within the first 24 hours after birth, the total serum bilirubin level rises by more than 5 mg per dL (86 micromol per L) per day or is higher than 17 mg per dL (290 micromol per L), or an infant has signs and symptoms suggestive of serious illness. The management goals are to exclude pathologic causes of hyperbilirubinemia and initiate treatment to prevent bilirubin neurotoxicity.

Therapeutic hyperthermia: The old, the new, and the upcoming.

Abstract: Hyperthermia has long been used for cancer treatment, either alone or in combination with chemotherapy, radiation therapy, or both. Its efficacy and versatility continue to be well demonstrated in randomized trials across a number of primary cancers, but barriers to its widespread adoption persist including effective delivery and verification systems. This article describes hyperthermia, details its biological mechanisms of action and immunological effects, and summarizes select preclinical data and key clinical trials combining hyperthermia with standard cancer treatments. Current challenges and emerging technologies that have the potential to make this translational therapy more accessible to a greater number of patients are also described.

A Prospective Study of the Incidence of Myocarditis/Pericarditis and New Onset Cardiac Symptoms following Smallpox and Influenza Vaccination

Abstract: Background Although myocarditis/pericarditis (MP) has been identified as an adverse event following smallpox vaccine (SPX), the prospective incidence of this reaction and new onset cardiac symptoms, including possible subclinical injury, has not been prospectively defined.
