Is there any role for bisphosphonate or alternative bone-modifying agents use in SMM in the absence of other indications for its use?
The short answer is no, unless the patient has an indication like osteoporosis. Bisphosphonates have been evaluated in smoldering multiple myeloma in studies performed over 10 years ago. Treatment with pamidronate (D’Arena et al., 2011) or zoledronic acid (Musto et al., 2008) did not affect the time...
In ischemic stroke patients with low LDL levels (<30-50 mg/dl), would you consider lowering LDL levels to lower values without concern for any side effects?
If LDL levels are already below 70, I don’t target a lower goal. The SPARCL trial showed that reducing LDL to this range has an NNT of about 45 to prevent one stroke, which I find to be modest at best. From my perspective, lowering LDL further (<30-50 range) shifts the focus to treating a number rat...
Is it a good practice to prescribe clonidine to take as needed for occasional severe blood pressure elevations?
Prescribing as needed clonidine is not part of my routine BP management. If the BP is uncontrolled consistently then long-acting medications can be uptitrated or dose adjusted. As needed clonidine may be helpful in the initial evaluation period or when making medications changes. It is important for...
What are your preferred lipid-lowering agents and target LDL reduction goal following initiation of therapy for patients with familial hyperlipidemia without underlying CAD?
It is not easy to address this question without specifics of the 'familial hyperlipidemia," but I will give examples: Monogenic familial hypercholesterolemia - since the LDL is very high from early childhood, we tend to treat adolescents with statins with a goal of a 50% reduction (20 or 40 rosuvas...
How do you counsel patients that are positive for both stimulatory and inhibitory autoimmune thyroid markers (TRAb, TSI and TPO Ab) regarding their likelihood of flipping from hyperthyroidism to hypothyroidism?
I do not measure multiple thyroid antibodies simultaneously at the time of initial diagnosis, so this is typically not a conversation I would have at initial patient presentation. My usual practice is to check a TSI in patients with hyperthyroidism and a TPO in patients with new hypothyroidism. In p...
What are some practical tips in distinguishing between metabolic bone disease due to chronic kidney disease and osteoporosis?
The biggest difference between osteoporosis and CKD-MBD has to do with the underlying bone mineral laboratories. Generally, with osteoporosis, bone chemistries are relatively normal; there may be a decrease in Vit D. However, with CKD-MBD, there is usually an increase in PTH, potentially abnormaliti...
Would you recommend RAI ablation therapy to patients with PTC who are s/p hemi-thyroidectomy and decline completion thyroidectomy despite meeting criteria based on pathology results?
RAI therapy will work to ablate the remaining thyroid lobe with about a 69% success rate using a high dose of I-131. However, extra-thyroidal tumor cells will likely not pick up I-131 with this treatment. A good reference is the 2020 meta-analysis in the Journal of Nuclear Medicine: Piccardo et al.,...
Would you recommend discontinuing testosterone replacement in a male patient in his 60s with newly diagnosed favorable intermediate-risk prostate cancer who is declining surgery and will receive definitive radiation?
Historically, we (as a field) have viewed TRT as the opposite of ADT and therefore inherently problematic. I am not convinced this is logical. ADT has RCT evidence to support it, whereas withdrawing TRT has not been as cleanly studied. Let's say we stop TRT, and this drops their testosterone to 150 ...
Do you interpret failure to develop hypernatremia with prolonged water deprivation (such as for 12 hours) as evidence against diabetes insipidus even if the urine osmolality is just below normal?
This test indicates that this patient has fairly good urinary concentrating ability, but does not meet most criteria for "normal" since the osmoles did not go over 600. Since diabetes insipidus is a spectrum disorder, this result does not completely rule out the possibility of very mild diabetes ins...
In patients with severe osteoporosis, history of retinal artery occlusion, and hypercalciuria, would you favor PTH analogue therapy or Evenity?
Assuming that PTH and vitamin D are normal, neither. Chlorthalidone is the treatment of choice in this scenario. Chlorthalidone is usually better than HCTZ, as HCTZ often must be given BID, whereas chlorthalidone can be given daily. I have seen very large improvements in BMD with thiazide therapy, o...
