Would you expect a reduced neutrophil count in individuals with a partial duffy null phenotype?
The Duffy null phenotype's impact on neutrophil counts is "all or none". Approximately one-third of patients with the Duffy null phenotype Fy (a-b-) will have a neutrophil count below the usual lower limit of normal. The range of neutrophil counts in individuals with Fy (a+b-) and Fy (a-b+) is exact...
In what clinical scenario would you consider liver transplant evaluation for a patient with sickle cell hepatopathy?
We have evaluated and transplanted patients with sickle cell hepatopathy with severe liver dysfunction but well-controlled sickle cell. These patients will typically have jaundice, coagulopathy, and biliary strictures. They should not have significant extrahepatic complications of the hematologic di...
How do you decide whether to hold acalabrutinib or zanubrutinib in patients with indolent B-cell lymphoma/leukemias in a perioperative/periprocedural setting?
This is always a point of discomfort among providers, but it can actually be made quite easy. BTK inhibitors have known antiplatelet effects similar to low-dose aspirin. Consequently, if the surgeon holds aspirin for the planned procedure, I generally recommend that we hold the BTK inhibitor for 3 d...
What GDMT do you recommend for patients with AL amyloidosis and systolic heart failure?
You are correct that cardiac amyloidosis patients do not tolerate most of the GDMT. SGLT2i may be helpful for both diuresis as well as HFpEF, and we do try to start this. Generally, they do not tolerate ARB/ACEI or even beta blockers. We find that torsemide seems to have better GI absorption and thu...
For patients with newly diagnosed unmutated CLL how will you decide between BTKi alone vs Ven/BTKi vs Ven/Obin vs Ven/Obin/Acalabrutinib?
My usual practice has been Ven Obin for most patients, even unmutated, but if they have bulky nodes and are young/fit, I am now adding acala to that and giving the 3-drug regimen. Continuous BTKi in my practice is mostly reserved for the older or less fit patients, or those who really, really don’t ...
What is your approach to VTE prophylaxis in hospitalized patients who are already on DAPT?
DAPT by itself is not considered DVT prophylaxis in patients at high risk of DVT. However, LMWH at prophylactic doses can increase the need for transfusions in patients on DAPT, without decreasing VTE rates. In general, I consider patients individually: Do they still need DAPT? With discontinuity o...
Should all patients diagnosed with B12 deficiency get a baseline EGD?
It is important to determine the cause of B12 deficiency. The majority of cases are due to pernicious anemia (atrophic gastritis and lack of intrinsic factor), I presume this question relates to that group. If there is another cause such as intestinal malabsorption or bacterial overgrowth, this does...
How will you use Pola-R-CHP in the frontline treatment of DLBCL?
Given the comparable toxicity profile and the lower rate of treatment failure, the number needed to treat (n=16) is low enough that this is very appropriate to be the new standard of care. Although overall survival was not different, fewer patients treated with the Pola-R-CHP regimen required subseq...
Which neoadjuvant/adjuvant chemotherapy regimen would you select in a patient with resectable stage IB pancreatic head adenocarcinoma and MDS-SF3B1 on luspatercept (baseline Hgb of 8-9 g/dL)?
Seems a bit unfair that the patient has both! First, I would consider resection upfront to ensure this key step rather than risk additional complications of chemotherapy. Perioperative or total neoadjuvant therapy is not standard for resectable disease yet (pending Alliance trial result). Second, bo...
Would you consider anti-fibrinolytics for heavy menses in patients with a history of VTE?
A recent review article provided reassuring evidence about the combined use of antifibrinolytics and estrogen in women with heavy menstrual bleeding (Meschino et al., PMID 40680937); however, it did not specifically provide data in women with a prior history of VTE. In this case, I would first ensur...
