Do you escalate to 7.2 mg semaglutide in a patient with obesity who has not achieved their weight loss goal on the 2.4 mg dose despite the increased risk of dysesthesia at the higher dose?
This question is raised because of a recent report (Wharton et al., PMID 40961952) looking at weight loss in obese patients titrated up to 7.2 mg/week of semaglutide compared to the usual dose of 2.4 mg/week. The study was funded by Novo Nordisk, and the authors have strong financial ties to the com...
When starting GLP-1 R agonist therapy for weight loss purposes, how do you counsel patients on duration of treatment therapy?
I counsel people that I expect this to be lifelong therapy (similar to how we don't stop blood pressure medications when blood pressure comes down to normal on them because it will go back up, we don't stop GLP1RA when we get to our weight goals, as our weight will go back up when they are stopped)....
How do you counsel patients on semaglutide or tirzepatide in light of potential cancer risks?
Use of GLP 1 RAs has sky-rocketed in recent years due to what seems to be a positive class effect on T2DM, weight loss, renal outcomes, cardiac outcomes and hepatic outcomes. I am not aware of any signals of increased malignancy risk. A brief literature review found meta-analyses showing possible be...
How do you counsel patients on the risks and benefits of strontium supplements for osteoporosis management?
No experts whom I know prescribe Strontium for osteoporosis. It has not been shown to be efficacious to reduce fractures, although bone density will rise substantially. Also, bear in mind of very serious toxicities that have been associated with this drug. I would never use it in any of my patients....
How do you decide when to act upon TFT derangements in hospitalized patients (e.g., start/adjust thyroid replacement therapy) vs attribute to NTIS (formerly euthyroid sick syndrome) and advise repeat TFTs as an outpatient?
It is not always easy to discern, but typically in NTIS, T3, T4, and TSH are all low or normal (TSH may be slightly elevated but not markedly elevated). True hypothyroid (requiring new medication or adjustments of existing medications) typically has a high TSH and low Free T4, and the patient may ha...
For patients with Hashimoto's thyroiditis, is there a commercially available blood test for detecting abnormalities in the type 1 deiodinase enzyme in order to identify patients who would potentially benefit from T4 and T3 combination therapy?
Most clinicians decide to use combination therapy based on a weak response to levothyroxine, with patients still complaining of symptoms related to hypothyroidism. The TSH should not be low before selecting dual replacement.
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...
What triggers you to choose urgent thyroidectomy versus therapeutic plasma exchange versus continued medical management for refractory thyroid storm despite 12-24 hours of guideline-concordant therapy?
A very important factor is the comfort level of the ICU doctors and the Anesthesiologists at the institution. We usually do not recommend proceeding with urgent thyroidectomy given the increased risks, unless FT4 and TT3 are normalizing. Usually, a combination of PTU (or Methimazole), stress dose st...
Can autoimmune thyroiditis present with recurrent angioedema and bronchospasm?
There is an association between angioedema and autoimmune thyroid disease, although the incidence is not known. Activated CD4+ T lymphocytes, monocytes, and eosinophils. The incidence of thyroid autoimmunity in chronic urticaria is similar to the background population, but there is a cluster of angi...
How would you counsel patients with type 1 or type 2 diabetes mellitus and heart failure on the use of SGLT-2 inhibitors when they have a history of DKA?
Making a recommendation to prescribe this class will really require a case-by-case clinical assessment. It is clear that SGLT-2 inhibitors are very effective in preventing hospitalization for heart failure, and so we will want to suggest their use whenever possible. But it is also clear that DKA (mo...
