In an adult patient with asymptomatic, isolated neutropenia in whom you suspect a Duffy null phenotype, at what ANC or in what situations would you do a bone marrow to look for other etiologies of neutropenia?
What a great question! Happy to answer. As you know, as many as 60% of individuals who have the Duffy null phenotype will have an ANC that is lower than the lower limit of normal in many labs BUT as you also know, the total body (in circulation + in tissues) neutrophil count in such individuals is n...
When would you consider use of emapalumab for HLH/MAS?
The FDA has approved emapalumab for familial HLH. For secondary HLH/MAS, I typically begin with anakinra (100 mg q 6 hrs for those 40 kg or more). If this is not enough and if CXCL9 (I send on day one to have the data available) is notably elevated, then consider adding emapalumab. Alternatively, a ...
What are your top takeaways in Hematologic Malignancies from ASH 2024?
Abstract 1009 - Multiple important studies were presented at the recently concluded ASH meeting. From the CLL perspective, one of the most impactful studies was the AMPLIFY clinical trial that compared acalabrutinib plus venetoclax with or without obinutuzumab versus chemoimmunotherapy for first-li...
Do you use G-CSF for a patient with ALL admitted for febrile neutropenia with prolonged count recovery?
Acknowledging the lack of definitive data, in our group we use G-CSF as primary prophylaxis in adult patients with ALL treated with intensive chemotherapy and hardly ever need to re-administered if they develop FN subsequently. That said, for prolonged neutropenia despite prior G-CSF, we may adminis...
How would you manage aplastic anemia refractory to multiple agents?
If indeed the patient has been treated with all reasonable alternatives to BMT, the choices are 1) watch and wait with supportive care or 2) bone marrow transplantation. I understand the reluctance of transplanting someone in their 70s with aplastic anemia; however, we do this routinely in patients ...
How would you approach adjusting nivo+AVD therapy for advanced Hodgkin lymphoma if a patient develops treatment limited immunotherapy toxicity?
BV-AVD-related transaminitis is relatively common; however, even with Nivo-AVD, transaminitis is frequently observed, albeit at a lower frequency. Most of these events are self-limited and grade 1-2. Depending on the stage and severity of the event, dose holds can be employed; however, adverse event...
How do you counsel an otherwise healthy patient on how soon they can go back to moderate exercise after a bilateral pulmonary embolism?
Generally, the approach is to have the patient start their exercise regimen at a lower intensity and gradually increase it based on their tolerance.
How should dose homogeneity across bone be handled in pediatric patients?
The radiation-associated bone damage can be affected by many factors, including total radiation dose, fractionation schedule, treatment volume, age of the child, symmetry of the delivered dose over vertebrae, developmental status of the irradiated growth plates, treatments such as chemotherapy or su...
What is your approach to further work-up and management of neutropenia in patients with SLE/RA overlap?
This is an interesting situation that comes up in the routine evaluation of patients with rheumatoid arthritis and other autoimmune syndromes. The normocellular bone marrow suggests a peripheral destruction, in general, and raises some concerns for antibodies directed against neutrophils. These are ...
How do you manage a patient with sickle cell disease during pregnancy?
I refer all pregnant women with SCD to maternofetal medicine/high risk pregnancy clinic for more frequent monitoring. I recommend a baby aspirin for preeclampsia prevention (see UK guidelines). I recommend folic acid 4 mg. If they do have iron overload, I do not recommend iron supplementation. For a...
