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...
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...
How do you approach DOAC dose reduction for secondary prophylaxis of VTE in cancer-associated thrombosis?
Data from the API-CAT trial (Mahé et al., PMID 40162636) show that de-escalation of apixaban after 6 months was non-inferior compared to the standard dose with respect to recurrent VTE. Although there was no difference in major bleeding, the lower dose of apixaban was superior from the clinically re...
How do you manage patients with atrial fibrillation having a thromboembolic infarct despite being on adequate anticoagulation?
This scenario is always challenging. In terms of anticoagulation, the efficacy of DOACs in preventing embolic events in AF patients is around 70%, which is impressive compared to warfarin but not foolproof. In cases of a second embolic event while on anticoagulation, two reasonable approaches are of...
What is your approach to a situation where DILI is suspected secondary to an important medication (e.g., anticoagulation, antibiotics, etc.), but the diagnosis is uncertain and the liver injury is relatively mild?
If the drug suspected to induce liver injury causes symptoms and ALT is >3 times the upper limit of normal (ULN), I would stop the drug and find an alternative. Even if no symptoms are present, I would stop if ALT is >5 times ULN. Any level increase of ALT below the above parameters would still requ...
Following long-term efficacy and safety data from the beti-cel trials, how do you approach gene therapy for eligible patients with transfusion-dependent β-thalassemia?
The results with beti-cel are excellent. So are the results with exa-cel. These two gene therapies use different approaches to modifying hemoglobin production in erythroid stem cells. Beti-cel adds a modified hemoglobin that resembles fetal hemoglobin using viral-mediated transduction, whereas exa-c...
Do you offer enasidenib with azacitadine in AML with an IDH2 mutation for patients ineligible for intensive induction chemotherapy?
I typically do not give enasidenib with azacitidine upfront for patients with AML with IDH2 mutation and ineligible for intensive induction chemotherapy. Based on the results of the VIALE-A study (DiNardo et al, NEJM 2020), I usually give venetoclax with azacitidine to those patients. In addition to...
How is the CARES kappa subgroup data changing your approach to newly diagnosed kappa AL amyloidosis?
Anselamimab (originally CAEL-101 & 11-1F4) is a chimeric immunoglobulin IgG1 kappa monoclonal antibody (mAb) directed against the human kappa light chain fibril and has shown preclinical reactivity against both isotypes, even though these preclinical studies seem like nonsense. It targets only the k...
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...
How do you decide when to pursue malignancy workup for patients with cryptogenic stroke?
Agree with above. I would also pursue malignancy work-up in this scenario as well: currently on anticoagulation (whether for afib or another medical reason) and has an ischemic stroke on top of that.
