In a patient with cryptogenic stroke while on antecedent aspirin 81 mg, how do you decide between single antiplatelet therapy, dual antiplatelet therapy, or antiplatelet agent combined with anticoagulation such as rivaroxaban 2.5 mg BID?
This question assumes that a thorough workup has been completed, and the patient does not have paroxysmal a fib, a PFO, an intracranial stenosis, a hypercoagulable state, or vasculitis. This workup is the most important issue. If all is negative, and the stroke is relatively minor (NIHSS less than o...
How would you best evaluate and manage a patient with hemiplegic migraine and a history of ischemic stroke?
Without further information, I would say that these two conditions, hemiplegic migraine and ischemic stroke, have nothing to do with each other. Hemiplegic migraine should be evaluated and managed as migraine with gepants ideal for abortive treatment and CGRP antibodies for preventive treatment if n...
Do you recommend repeat kidney stone composition testing for a patient with recurrent nephrolithiasis who passed an additional stone but previously already had stone composition testing performed?
Good question. Certainly, if there has been a gap in stone events prior to new development of stones, it is reasonable to confirm both the stone composition and the 24-hour urine chemistry, to see if conditions have changed in a meaningful way. It would be less important, if the patient had regular ...
Is the phosphorus-lowering benefit of patiromer compelling enough to switch a patient with chronic hyperkalemia and hyperphosphatemia from sodium zirconium cyclosilicate to patiromer?
I don't think so but I think Patiromer is a better agent anyway as it does not have sodium in it. Patients with CKD and especially dialysis patients are often volume overloaded. It definitely makes sense to use an agent that does not have sodium in it.
Would you treat a patient for heterotopic ossification prophylaxis if >72 hours after surgery?
RT is very effective in reducing heterotopic ossification that can happen after surgery/trauma to the hips. We have always been taught to do either before 24 or less before surgery or within 72 hours after surgery. The rationale is that RT prevents HO by the inhibition of osteoprogenitor cells proli...
How long do you monitor proteinuria after starting an SGLT-2 inhibitor before considering adding another medication if proteinuria is not at goal?
I would typically wait 2-3 months. Most such patients should be on RAAS blockade which should be maximized if tolerated first.
At what point should aspirin therapy for stable cardiovascular disease be discontinued in patients with a diagnosis of chronic cerebral microbleeds or possible Cerebral Amyloid Angiopathy?
I would continue low aspirin indefinitely.
How soon after an end stage kidney disease patient receives a MRI study with gadolinium contrast do you perform their next hemodialysis session?
Very contentious question. But as an author of the NKF and ARA position paper on this, I would follow our advice, no need to dialyze immediately after, but try to time the study with the next dialysis.Weinreb et al., PMID 33170103ASN Communities (for ASN members) had a VERY LONG post on this general...
What treatment options would you consider for a young patient with limited mobility, low bone mass and multiple vertebral compression fractures who is on dialysis for advanced kidney disease?
There are a lot of variables to this question. I would worry that the person may have a variant of OI (osteogenesis imperfecta) or some other collage problem and then add renal failure to the mix. I would try to establish the causes of each problem first such as steroid induced bone disease or a bon...
For patients with essential thrombocythemia already on prophylactic dose DOACs, do you defer starting aspirin?
I usually defer aspirin in these situations. There is evidence from PV that aspirin plus anticoagulation increases bleeding risk (Zwicker et al., PMID 34162181). If an ET patient has a high-risk disease with prior arterial thrombosis, then I would favor adding aspirin.
