How do you manage dose titration and nutrition to avoid sarcopenia when prescribing a GLP-1 receptor agonist in a frail older adult with MASLD?
GLP-1 and GLP-1/GIP receptor agonists as a class have been found to be effective in improving MASLD (Loomba et al., PMID 38856224) in patients with and without diabetes. This large class of drugs(more are on the way) also causes significant weight loss, and newer iterations may lower BMI into the no...
How do you evaluate remission in acromegaly when postoperative IGF-1 and GH levels are discordant?
It depends how long after surgery. IGF-1 may take up to 3 months form curative surgery to normalize. If GH is low (<0.4 ng/mL) and IGF-1 is still abnormal and you are less than 3 months form surgery, I would just wait. If the opposite is true (Normal IGF-1 but elevated random GH), I would perform a ...
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...
Do you recommend monitoring Free T4 or Total T4 levels in pregnant patients with central hypothyroidism?
Free T4 immunoassays are inaccurate in pregnancy. In this scenario, I would either use total T4 with a goal range of 1.5 times the normal range, or I would order a "thyroid panel" that reports a Free Thyroxine Index, calculated from the total T4 and T3 resin uptake. The FTI is more reliable in pregn...
What is the accuracy of the 24 hour urine aldosterone level when performing confirmatory testing for hyperaldosteronism in patients with advanced CKD?
I don't do confirmatory testing when renin is suppressed and aldosterone is >10 on repeated testing.
Do you recommend a particular antiresorptive/anabolic agent for patients who are at high risk for fractures but have high risk of osteonecrosis of the jaw?
Teriparatide has improved bone healing in patients with osteonecrosis of the jaw, so would be a good choice for patients at high risk of ONJ.
What is your preferred method for confirming the diagnosis of primary aldosteronism in a patient with an elevated plasma aldosterone to renin ratio?
The endocrine guidelines on primary aldo diagnosis (1) allow for 3 confirmatory tests: 24-hour urine, fludrocortisone suppression testing, and response to saline infusion. At UAB, we use the 24-hour urine collection. Most of our patients do not need additional salt loading during the 24-hour collect...
Would you consider PCSK9 inhibitors for patients with elevated coronary calcium score or coronary calcification for primary prevention in lieu of statins/ezetimibe and/or bempedoic acid?
Absolutely! The VESALIUS trial confirms that lower is better even in people without a prior event. I wouldn’t use a PCSK9i in lieu of a statin, though. I would add it to the statin if someone’s LDL-C is still elevated. If someone has a high CAC score, I target an LDL-C and apoB <55 mg/dL. Ezetimibe ...
In patients with confirmed hypercortisolism with a high/normal unsuppressed ACTH who have both a pituitary adenoma and adrenal adenoma identified on imaging, can you reliably use DHEA-S to determine the source of cortisol production?
There is a difference between high-normal and unsuppressed ACTH. If ACTH is high-normal, this is ACTH-dependent Cushing. However, you can have mild adrenal Cushing without fully suppressed ACTH (e.g., ACTH in the 10-20 pg/ml range and sometimes even above 20). I don't think you can rely on DHEAS in ...
How do you decide when to evaluate for central hypothyroidism in a patient with low-normal TSH and low free T4?
The differential in these patients is 1) mild subclinical hyperthyroidism 2) central hypothyroidism 3) normal variant related to assay detection limitations. It would be important to obtain a good history and try to identify any hypothyroid or hyperthyroid symptoms. Having said that, patients will u...
