Do you discontinue or adjust azathioprine when a patient develops elevated MCV after starting it?
Great question, with practical implications for the clinic: Azathioprine (AZA) is a prodrug that likely exerts its immunosuppressive effects against B- and T-cell function by interfering with purine metabolism through its metabolites (including 6-MP). Logically, many of the "classic" AZA side effect...
What autonomic symptoms do you encounter in patients with ALS?
In my experience, autonomic symptoms are not typical in ALS and we do not routinely ask screening questions for dysautonomia. A recent study from Europe (see below) suggests that the only sign of autonomic dysfunction is mildly increased heart rate at rest (which may also be attributed to other fact...
What duration of dual antiplatelet therapy do you use for secondary prevention of ischemic stroke due to intracranial atherosclerotic disease?
It is a fair question that we don't have a solid evidence-based answer for. I agree that the SAMMPRIS trial was driven by events within the first 30 days, although this was primarily driven by procedure-related events in the stented group. We do know that intracranial athero (ICAS) risk of stroke re...
How do you modify TNBC neoadjuvant chemotherapy in patients with multiple sclerosis?
This is a good, but tough question with unfortunately no great data to support the safety of immunotherapy combinations in patients with active autoimmune diseases including multiple sclerosis. While the significant improvement in pathologic complete responses with the addition of pembrolizumab to c...
If memantine were started 6 weeks after completion of radiation to base of skull, would you expect any potential benefit?
There is currently no credible high-quality data to support the use of memantine in focal brain RT for primary or metastatic brain tumors, regardless of whether the hippocampus is in the radiation field. Therefore, I would not prescribe memantine during or after RT in such a clinical setting. In my ...
Do you use vitamin B6 to help with Keppra irritability?
I am an adult epileptologist and do not routinely prescribe pyridoxine for neuropsychiatric adverse effects of levetiracetam. I do see this done a lot more in the pediatric population, where there is more data than is available in the adult population (though still not of very high quality). Anecdot...
How will you counsel patients regarding ARIA?
It is possible that with real-life experience and further study, blood biomarkers will be validated as early detection signs of ARIA, but right now we are left with MRI. I believe that we need a lot more real-world data about these drugs before we consider alternative ways to diagnose and screen for...
Do you screen adults in your practice with sickle cell disease for silent cerebral infarcts?
The details of the ASH guidelines regarding adults are complex. It was not my practice to screen all patients. More than 50% of adults have silent infarction. Screening requires MRI and this, according to the guidelines, needs careful attention to many details before it is reliable. There are no pro...
Would you hold CGRP (calcitonin gene-related peptide) monoclonal antibodies such as Eptinezumab-jjmr (Vyepti) before, during, or after lung SBRT?
No, I will not hold CGRP monoclonal antibodies during lung SBRT as at present, there is no data suggesting the detrimental effect of doing so. Moreover, the drug is conveniently given q 3months while SBRT is usually completed within 2 weeks. Therefore, most lung SBRT can be scheduled outside of the ...
Is there a role for unilateral hippocampal sparing?
There is some lateralization of hippocampus function which may impact decision making.The left hippocampus seems to play more of a role in episodic verbal memory, while the right plays more of a role in spatial processing. Our neurosurgeon has told me before that a left hippocampectomy is much worse...
