Would you use the pneumococcal conjugate-21 vaccine (Capvaxive) instead of the conjugate-20 (Prevnar-20) for routine vaccinations in immunosuppressed patients?
PCV-21 was recently approved by the FDA and supported by ACIP. At this early stage (August 2024), CDC has not finalized guidance on PCV-21, so we do not know how the vaccine schedule will be changed. An important distinction is that PCV-21 covers different serotypes of pneumococcus, as outlined in t...
When, if ever, would you select a three-drug regimen instead of four-drug regimen in patients with newly diagnosed Multiple Myeloma?
Thank you for this question. For older, transplant-ineligible patients, there is no data that patients live longer or better (the true goals of treatment) with four drugs instead of three drugs. Yes, the responses are better, and we hope this may translate to longevity over time, but we do not know ...
How do you decide between anticoagulation or portal vein recanalization in a patient with portal vein thrombosis?
It depends on cirrhotic vs non-cirrhotic. For cirrhotic, best to reference the AASLD 2020 guidance here - Northup et al., PMID 33219529.For non-cirrhotic: important to determine the etiology as well as evaluate for a hypercoagulable state, including checking for JAK2 and CALR.If acute and non-occlus...
How do you approach the risk/benefit discussion for IV iron in a patient with concomitant severe iron deficiency and elevated hematocrit due to supra-physiologic testosterone supplementation?
I only administer iron if symptomatic (pagophagia, RLS, etc). I have not seen iron deficiency with testosterone prior to phlebotomy. When it is required, I literally walk both sides of the aisle. If a non-phlebotomized patient presented with ID, I would work it up like any other. If I have to treat,...
In your practice, would you consider the all-oral option of decitabine-cedazuridine + venetoclax for an elderly, unfit AML patient, based on the ASCERTAIN-V trial results?
I see the combination of oral decitabine-cedazuridine (ASTX727) + venetoclax as largely being an appropriate option for any patient with newly diagnosed AML that would be otherwise considered for azacitidine + venetoclax. The inclusion criteria for ASCERTAIN-V (Roboz et al., PMID 42235013) and VIALE...
Do you use anti-microbial prophylaxis when you prescribe ibrutinib?
Traditionally, H.Zoster and PJP prophylaxis was more routinely administered in CLL patients receiving chemoimmunotherapy as these regimens were typically more myelosuppressive as well as immunosuppressive. In the era of the novel BCR receptor agents with the approval of ibrutinib and idelalisib and ...
How do you manage persistent cytopenias in patients with AML who achieve a complete remission with incomplete count recovery after venetoclax and HMA?
This is an important question. How to manage cytopenias on HMA + venetoclax-based regimens is one of the biggest conundrums in the management of AML. The clinical trials to date have not uniformly answered this question based on level 1 evidence. These recommendations are mainly based on anecdotal d...
Do you routinely stop ESA when starting myelofibrosis patients on JAK inhibitor therapy?
The management of myelofibrosis with anemia is becoming increasingly nuanced, given the several JAK inhibitors available to us and the potential for add-on therapies! An excellent resource to consider regarding decision-making is Jain et al., PMID 39808793. Regarding this specific question at hand, ...
Do you use lenalidomide for patients with MDS with 5q- without other cytogenetic abnormalities but with one or more mutations on NGS?
For patients who meet the definition of del(5q) syndrome, I typically utilize lenalidomide regardless of the molecular features of the disease. The original publication (List et al., PMID 15703420), the phase III MDS-004 study (Fenaux et al., PMID 21753188), and the phase III SintraREV study (Díez-C...
In a patient with negative Hep B surface Ag, Hep B surface antibody+, and Hep B core antibody+ serologies, do you initiate antiviral prophylaxis (e.g. entecavir) prior to starting rituximab?
I would use entecavir for Hep B reactivation prophylaxis in this case - based on recommendations from AGA 2025 guidelines, which does classify b-cell depleting agents as higher risk for reactivation for both Hep B surface Ag-positive and Hep B surface Antigen neg/core positive patients. It should be...
