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...
Do you routinely evaluate patients with collagen disorders or Ehlers-Danlos for platelet defects?
Yes, I routinely carry out a full hemostasis evaluation, including platelet aggregation and release studies, in patients referred to me with easy bruising and hypermobility with an increased Beighton score suggesting EDS and in those already diagnosed genetically with EDS. EDS patients typically hav...
What radiation doses and subsequent treatment monitoring would you recommend for multiple myeloma patients with multifocal bony lesions who decline chemotherapy?
Systemic therapy is the cornerstone of treatment for multiple myeloma, and the vast majority of patients initiate an appropriate regimen upon diagnosis. Occasionally, patients will have very limited disease and will be referred to Radiation Oncology for consideration of local therapy to delay the ne...
How do you manage anxiety in patients prior to bone marrow biopsy procedure in the clinic?
With the use of the drill procedure for bone marrow biopsies, my experience is that the pain element of this procedure has essentially been eliminated. Prior to this, we offered conscious sedation, when possible, to our patients because of the painful nature of the biopsy procedure, which is not aba...
For atrial fibrillation patients with high risk of CVA who cannot tolerate full dose AC due to bleeding, do you consider low dose/extended dosing anticoagulation even if they do not meet age/GFR criteria for a dose reduction, if Watchman is not readily available as an option?
Most drugs, including anticoagulants, have a dose-response. Therefore, one could argue that even though DOACs were not studied at low doses, except in defined sub-groups such as the very elderly, using such a dose in other situations may have some benefit. The problem is that without data, we simply...
What is your approach to systemic anticoagulation for patients with hypoalbuminemia and nephrotic syndrome secondary to a non-membranous nephropathy condition?
Patients with nephrotic syndrome (NS) and hypoalbuminemia have a several-fold higher risk of venous thromboembolism (VTE) than the general population and also a somewhat higher risk of arterial thromboembolism (ATE), such as MI and stroke. This risk seems to be higher in membranous nephropathy (MN) ...
How do you approach CNS prophylaxis in patients with DLBCL?
I think the NCCN-CNS-IPI based on the German data is a reasonable place to start when it comes to making decisions regarding CNS prophylaxis. We typically do IT MTX for patients on the lower end of the risk spectrum and high-dose IV MTX for patients on the higher end of the risk spectrum.
How do you decide whether to use pharmacologic VTE prophylaxis in hospitalized patients with decompensated cirrhosis?
For all patients, I begin by using a standard risk prediction tool to determine if the patient is appropriate for pharmacologic VTE prophylaxis. At our institution, the Padua risk prediction tool is embedded in our electronic health record/admission set. Clinical guidelines- including those from the...
Do you consider bleeding risk in elderly, frail patients with atrial fibrillation to be similar for all NOACs?
I believe that apixaban carries a lower risk of bleeding, with particular reference to GI bleed, when compared to rivaroxaban and dabigatran. This is true in the population of AF patients at large and most probably in frail patients as well.
How do you approach the outpatient management of bispecific antibody therapy for hematologic malignancies?
Multiple bispecific antibodies (BsAbs) targeting CD20 on lymphoma cells and CD3 on T-cells are now available in follicular and large B-cell lymphoma. A multi-disciplinary team with knowledge of the different BsAb indications and possible toxicities is an important aspect of safely administering thes...
