Ibrutinib-associated tumor lysis syndrome in chronic lymphocytic leukemia/small lymphocytic lymphoma and mantle cell lymphoma: A case series and review of the literature.

Background Tumor lysis syndrome results when intracellular contents are released during cell lysis. Ibrutinib, a Bruton tyrosine kinase inhibitor, is used for the treatment of chronic lymphocytic leukemia, small lymphocytic lymphoma, Waldenström's macroglobulinemia, mantle cell lymphoma, and marginal zone lymphoma. Tumor lysis syndrome caused by ibrutinib therapy is potentially life threatening, but is rare and not often reported in clinical trials.

Effect of selected clinical trial publication on adjunctive nonstatin medication prescribing in the Veterans Health Administration system.

Purpose: The question of whether publication of selected clinical trials is temporally followed by changes in prescribing of adjunctive lipid-lowering medications was evaluated.

Methods: In this retrospective preanalysis and postanalysis, Veterans Health Administration (VHA) patients 18 years or older who received a new or renewed order for any lipid-lowering medication between April 2, 2004, and September 2, 2014, were included. This period was chosen based on the publication dates of three trials investigating the efficacy of nonstatin medications: Simvastatin with or without Ezetimibe in Familial Hypercholesterolemia (ENHANCE, April 3, 2008), Effects of Combination Lipid Therapy in Type 2 Diabetes Mellitus (ACCORD Lipid, March 14, 2010), and Niacin in Patients with Low HDL Cholesterol Levels Receiving Intensive Statin Therapy (AIM-HIGH, December 15, 2011).
