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...
Is there a role for anti-fibrinolytic agents in patients with hyperfibrinolytic disseminated intravascular coagulation?
DIC is a complex clinicopathologic syndrome. There are no randomized trials to support evidence-based practice. The following principles apply: 1) antifibrinolytics should not be used in patients with organ failure or those that are asymptomatic. One could justify their use in this group of patients...
Would you recommend anticoagulation prophylaxis for a pediatric patient admitted with COVID-19?
COVID-19 disease in children seems to be less severe than adults based on the current literature and our personal experience at Children's Hospitals. Among adults, the coagulopathy is beginning to be described with elevated inflammatory markers and other markers of coagulation activation, including ...
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,...
For iron deficiency anemia due to heavy menstrual bleeding, what is your preferred method of controlling heavy menses?
I definitely loop in my GYN friends for this one! According to ACOG: "Heavy menstrual bleeding is defined as excessive menstrual blood loss that interferes with a woman's physical, social, emotional, or material quality of life." The consequences of HMB are substantial and multifaceted, and, as we f...
How do you approach a patient with IgM monoclonal gammopathy associated with severe neuropathy of unclear etiology?
I usually confirm if the patient does not have AL Amyloidosis or POEMS, and as part of work up for IgM MGUS, I order MYD 88 mutation. If all are negative and I still believe that neuropathy is caused from his/her MGUS, you can try IVIG for the neuropathy as a trial (of course after using gabapentin,...
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...
Are there any alternative, hypofractionated RT courses for patients with DLBCL that can be used during the COVID-19 pandemic?
ILROG recently came out with guidelines pasted below: Synopsis of ILROG Recommendations for Administering Radiotherapy for Hematological Malignancies During Emergency Conditions of the COVID-19 Pandemic • We are facing an increased demand for RT to substitute or complement systemic therapy deemed i...
In patients with iron deficiency due to history of gastric bypass or IBD, would you consider oral iron therapy if the iron deficiency anemia is mild?
Oral iron can often be effective in iron deficiency, as long as absorption is intact. If you are concerned about absorption, performing an oral iron challenge can be useful in allowing you to avoid long trials of oral iron that will be ineffective. Simply check an iron panel at baseline, then admini...
When do you pursue additional workup for incidental thrombocytosis in hospitalized patients?
Since most acutely ill patients will have lab evidence of acute illness, including thrombocytosis, I usually do not work it up during the hospital stay. But it should be stated in the discharge summary and followed up post-discharge.
