Background & Aims: Studies of the effects of direct oral anticoagulants (DOACs) in patients with cirrhosis have been limited by their small sample size, inclusion of patients with well-compensated cirrhosis, short follow-up times, inadequate validation of cirrhosis diagnoses, and non-standard definitions of bleeding. We aimed to systematically determine the characteristics, indications, and outcomes of patients with cirrhosis of all severity classes who received DOACs.

Methods: We performed a retrospective study of 138 patients with confirmed cirrhosis (93 with Child-Turcotte-Pugh scores of B or C) at a single center who started DOAC therapy (58,984 person-days; median, 181 days per patient) from September 2011 through April 2019. We collected data on clinical characteristics, indications for DOAC use, and outcomes. Standardized and validated definitions for bleeding complications were used.

Results: Twenty-nine patients (21%) stopped therapy due to a diagnosis of or perceived bleeding. The most common bleeding events were non-variceal upper and lower intestinal bleeding. No pretreatment laboratory parameters were associated with bleeding while patients received treatment, including platelet count (P = .50), international normalized ratio (P = .34), creatinine (P = .27), and model for end-stage liver disease score (P = .22). Frequency of bleeding events related to DOAC did not differ significantly among patients of different Child-Turcotte-Pugh classes (P = .81), DOAC indications (P = .60), or DOAC dosages (P = .10). Higher proportions of patients with hepatocellular carcinoma (P = .01) had major bleeding while receiving.

Conclusions: Patients with decompensated cirrhosis have significant bleeding and rates of discontinuation of DOACs when they take them long term. Pretreatment laboratory parameters, DOAC dose, and Child-Turcotte-Pugh class were not associated with bleeding; hepatocellular carcinoma was associated with major bleeding.

Evaluation of cardiomyopathy in acute myeloid leukemia patients treated with anthracyclines.

J Oncol Pharm Pract 2020 Apr 9;26(3):680-687. Epub 2019 Sep 9.

Department of Medicine, Division of Hematology/Oncology, University of Virginia, Charlottesville, VA, USA.

Background: Acute myeloid leukemia patients receive anthracycline-containing induction chemotherapy. Anthracyclines cause cardiotoxicity; however, there is a paucity of data reflecting the risk of cardiotoxicity in the acute myeloid leukemia population, and risk factors for development of reduced left ventricular ejection fraction are not well established in this population.

Methods: A retrospective cohort study of adult acute myeloid leukemia patients receiving anthracycline-containing induction chemotherapy between March 2011 and August 2017 was performed. Baseline and all additional cardiac monitoring within one year of induction were collected. Home medications and new medication initiation were determined via the electronic health record and new outpatient prescriptions.

Results: Of 97 evaluable patients, 25 (25.8%) developed reduced left ventricular ejection fraction and 18 (18.6%) experienced clinical heart failure within one year of induction. The median difference from baseline to lowest left ventricular ejection fraction was -5.0 percentage points, with a range of +10.0 to -52.5. The median time to onset of reduced left ventricular ejection fraction was 27 days, at a median cumulative anthracycline dose of 270 mg/m. No patient-specific or medication-specific factors were significantly associated with the risk of developing reduced left ventricular ejection fraction. Of 14 patients started on medical management for reduced left ventricular ejection fraction, 10 (71%) responded to therapy.

Conclusions: In this retrospective analysis, we observed that acute myeloid leukemia patients experienced reduced left ventricular ejection fraction more quickly and at lower doses than previously reported in the solid tumor population. Reduced left ventricular ejection fraction was at least partially reversible in most patients started on medical management. Although no factors were significantly associated with decreased cardiomyopathy risk, future assessment of cardioprotective medications may be warranted.
