TRAINING and EDUCATION You Make the Call Each month in “You Make the Call,” we’ll pick a challenging clinical question submitted through the Consult-a-Colleague program and post the expert’s response. But, what would YOU do? We’ll also pose a submitted question and ask you to send your responses. See how your answer matches up to the experts in the next print issue. This month, Sonali M. Smith, MD, advises on the use of pegfilgrastim with ABVD for treating Hodgkin lymphoma. Next Month’s Clinical Dilemma: Clinical Dilemma: How would you respond? Email us at [email protected]. What is your opinion on the use of pegfilgrastim with ABVD for classical Hodgkin lymphoma? Is it necessary, or would you treat without regard to neutrophil count and include it only if the patient has a neutropenic fever event? Consult-a-Colleague is a service for ASH members that helps facilitate the exchange of information between hematologists and their peers. ASH members can seek consultation on clinical cases from qualified experts in 11 categories: Experts Make the Call Sonali M. Smith, MD Associate Professor of Medicine Director, Lymphoma Program The University of Chicago Medicine An every-two-week regimen would not be appropriate for a long-lasting growth factor. For these reasons, our practice has been to use prophylactic antimicrobials (usually aciclovir, sulfamethoxazole/trimethoprim, and a quinolone) if there is prolonged neutropenia and to give this prophylaxis for the duration of therapy. If a patient develops a neutropenic infection, then we add in support with filgrastim.

In addition, there are retrospective data from several institutions demonstrating that the addition of pegfilgrastim to a bleomycin-containing regimen is associated with an increased risk of bleomycin-induced lung injury. We published our own citywide experience with elderly patients with Hodgkin lymphoma in Blood.1 In this population, the risk of lung injury with growth factors led to a very high percentage of pneumonitis, which was fatal in 30 percent of cases. The American Society of Clinical Oncology and National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology recommend restricting pegfilgrastim use to regimens with at least 21 days between exposure to chemotherapy. Is it reasonable to use rivaroxaban as an antithrombotic drug in patients with very high body mass index (>40 kg/m2)? *If you have a request related to a hematologic disorder not listed here, please email your recommendation to [email protected] so it can be considered for addition in the future.
