What is your approach to iron supplementation in patients with an active infection?
In patients with active infections, I generally avoid intravenous iron due to the potential for promoting pathogen growth, a practice supported by cautions from nephrology and gastroenterology society guidelines. However, evidence for the risk of infection with IV iron is inconsistent, underpowered,...
Would you stop current immunosuppressive therapy or delay starting immunosuppressive therapy in a patient with aplastic anemia who has been infected with COVID-19?
This is an interesting question. Based on personal communication (Italy, Germany, Israel), we have not seen increased risk for pediatric patients with hematological diseases and COVID-19. There was one case reported in China, but it was inconclusive (nearly 50 y.o. patient with aplastic anemia—seeme...
When do you opt to administer IV iron for patients with heart failure who may also have anemia of chronic disease or at risk for iron deposition disease?
I do not hesitate to administer IV iron in a patient with heart failure (chronic inflammation) if serum ferritin levels are <30 ng/ml and TSAT is under 20%. This is the only way, besides blood transfusions, to improve Hgb levels in this patient population.
Has your practice changed to PLEX-free initial therapy for iTTP?
I am not. The reason is that caplacizumab is not on formulary at my institution, and so implementing PLEX rapidly while obtaining caplacizumab (which typically arrives in 24-48 hours) is my current practice. If I had caplacizumab on formulary, I would utilize it as it was utilized in the MAYARI tria...
What screening tools or signs do you use to predict if a cancer patient is near end-of-life?
For most of us, long-time practicing oncologists, all we have to do to determine that one of our patients is at the end of their life is to be in the same room with them. No special computer programs or calculators are needed. Just look closely at the patient's current weight, their level of conscio...
How do you approach a patient with recurrent VTE who develops VTE again after reduction of apixaban to 2.5 mg bid?
Several factors play into this decision for me. Is the patient obese? Obese patients tend to give me pause for dose-reduction of DOACs. As such, half-dose apixaban may have been relatively underdosed for an obese patient and I would not call it DOAC failure, rather I would increase the dose to usua...
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 counsel a patient diagnosed with HTLV after an abnormal blood donor screening, especially in light of new data that dolutegravir may reduce uncommon but severe neurological outcomes associated with infection?
We actually do not see many individuals with HTLV disease at present in the US. Having said that, HTLV is a retrovirus, so it is biologically plausible that integrase inhibitors (like dolutegravir) could reduce viral spread in the body. However, the key counseling message is: evidence is still emerg...
How do you counsel patients on the risk of thromboembolic complications with use of immunotherapy in NSCLC?
Patients with metastatic lung cancer are at increased risk of thromboembolic events with an estimated frequency of 13.9% (Connolly et al., PMID 23026639). Preclinical data show that PD-1/PD-1 pathway blockade may lead to increased levels of pro-inflammatory cytokines and T cell driven progression an...
How do you decide between blinatumomab or traditional chemotherapy in combination with TKI for upfront treatment of adult patients with Ph + ALL?
This question is likely inspired by the recent publication of a "chemotherapy-free induction and consolidation first-line treatment" for adults with Ph+ ALL (Foà et al., PMID 33085860; GIMEMA LAL2116). The authors reported relatively high rates of MRD- remissions by bone marrow BCR-ABL1 RT-PCR and i...
