In a patient with Type I von Willebrand disease with history of VTE and heavy menses, would tranexamic acid be a treatment option?
No, with thrombosis one would not inhibit the thrombolytic pathway. Would anticoagulate with Coumadin with low INR 1.5 to 2.
When do you stop trying to eradicate an acquired factor VIII inhibitor?
First, to be clear, the answer to this question is not well studied in any population, and the clinical setting (i.e. age, titer - historical max or current), and the nature of the complications isn't detailed here. I presume "no causative etiology" includes "not postpartum, and not accompanied by (...
Other than B12 repletion, is there any further treatment or work-up indicated in pernicious anemia with positive parietal cell antibodies?
Pernicious anemia is an autoimmune disorder that can occur as a componet of multiple endocrine adenopathies, so evaluating the patient for thyroid, parathyroid, adrenal, etc. disorders is indicated both short and long term. More controversial is how to monitor the increased risk of stomach cancer as...
How do you approach work-up for a patient suspected for monoclonal gammopathy of renal significance for whom renal biopsy is contraindicated?
Not very many reasons that a renal biopsy could not be done, but I would consider doing a bone marrow biopsy if the free light chain ratio was significantly abnormal, i.e. a ratio of 3 or greater. A reminder that in renal failure, both light chains may be elevated, but the ratio in benign processes ...
Would you consider antiphospholipid syndrome to be a contraindication for checkpoint inhibitor immunotherapy?
Checkpoint inhibitor therapy is usually an important treatment for patients with advanced malignancy, and has greatly improved the prognosis of otherwise untreatable cancers, so I would not automatically proscribe these drugs because of a history of APS. I would ensure patients with APS are on full ...
How do you explain TTP to patients?
I tell them there is an enzyme in their blood called ADAMTS13 that helps keep their platelets from sticking together and plugging small blood vessels, and that for unknown reasons, their own immune system is destroying this enzyme. The symptoms of TTP are caused by clumps of stuck-together platelets...
What aspirin dose do you favor for thrombotic prophylaxis in myeloproliferative neoplasms?
I generally use 81 mg twice a day. If they have had a thrombotic event, or have microvascular symptoms, then I use 81 mg BiD.
How would you treat a patient with recurrent DLBCL 15 years after definitive treatment of initial de novo disease with R-CHOP?
As a new primary DLBCL, but with previous exposure to 6 cycles of doxorubicin, I would only give RCHOP x 2, then RCEOP x 4. If interim PET showed a poor response, I would switch to a CAR T-cell therapy as 2L therapy.
Do you hold histone deacetylase (HDAC) inhibitors for patients receiving palliative radiation therapy for cutaneous lymphomas?
Histone deacetylase (HDAC) inhibitors are often used in the management of mycosis fungoides, the most common cutaneous lymphoma. NCCN guidelines include two HDAC inhibitors in their list of recommended systemic therapies- romidepsin and vorinostat. Romidepsin was FDA approved for CTCL in 2009 and vo...
Do you offer anticoagulation to patients with prior antiphospholipid antibodies detected in pregnancy without a history of pregnancy loss or thrombosis?
I do not know what the risk of pregnancy loss is in a woman without a prior history of VTE or pregnancy loss. I am sure the risk is affected by whether the woman has an underlying rheumatological disease (SLE) and whether she has single positive vs. triple positive LAC. I recommend a baby aspirin on...
