What is the clinical significance of positive anti-thyroid antibodies in a patient that is post-thyroidectomy?
Ordinarily, the persistence of anti thyroperoxidase antibodies (antiTPO) or antithyrogloblin (antiTG) antibodies is of no concern or clinical relevance. However, in the case of patients with differentiated thyroid cancer, in whom thyroglobulin (TG) testing is a cornerstone of follow up, persistent a...
How do you handle elevated blood calcium levels from lithium?
Lithium in the past would often show up as calcium on blood tests, leading to an artificially elevated level. I don’t know if the modern tests have fixed that. Usually, I will watch it if over time the calcium is only mildly elevated, or refer for further workup (such as parathyroid issues, bone iss...
How do the results of the ESPRIT trial, which evaluated the impact of an SBP target of <120 mmHg on preventing major cardiovascular events, influence your blood pressure management goals for hypertensive patients with diabetes or a history of stroke?
The ESPRIT trial largely validates findings from SPRINT in a Chinese population. One major difference is that 38% of ESPRIT participants had diabetes mellitus (DM). A reduction in death from a CV cause drove the significance in the primary outcome (similar to SPRINT), and BP was measured 3x after a ...
Are there instances when you would recommend against pursuing adrenal vein sampling in a patient with primary hyperaldosteronism and normal adrenal imaging?
Yes, it is not uncommon for patients to choose not to pursue an adrenalectomy. I do not get the adrenal vein sampling (AVS) until I've had a discussion about the risk/benefits of adrenalectomy. Sometimes, I'll have them visit the surgeon before attempting an AVS to get a full picture of the surgery ...
Would you consider using Evenity in an elderly patient with rate controlled atrial fibrillation without history of MI or CVA?
The cardiovascular safety profile of Evenity is complex and has been reviewed in several publications. The concern is myocardial infarction and stroke. In general, if there is a history of an MI or stroke I would personally avoid Evenity. Although I do not have access to the safety dataset, I am una...
Should metformin be used in women with PCOS for weight loss?
I would not use metformin with the goal of weight loss in PCOS. Its effects on weight loss are modest (probably a few kg at most) and inconsistent. I agree with the Endocrine Society 2013 guidelines and that recommend metformin should not be used for the treatment of PCOS unless there is coexisting ...
Can FHH present with marked hypercalcemia (e.g., >12 mg/dL)?
Although unlikely, there have been several reports of FHH with parathyroid adenoma. FHH should have a setpoint. If you have previous blood calcium levels and the calcium has risen, I would search for a parathyroid adenoma.
Do you routinely use imaging (US, whole body iodine scans etc.) to follow papillary or follicular thyroid cancer after thyroidectomy and RAI therapy?
I am unaware of any prospective data suggesting a DFS or OS benefit to periodic imaging in patients with well differentiated thyroid cancer; that being said, beyond annual MMGs for our breast cancer patients, is there any benefit to any surveillance imaging in any malignancy? That has been recently ...
How often and in what way do you monitor patients who are receiving teprotumumab (Tepezza) for thyroid eye disease?
A week or two after completion unless having an issue.
In obese men presenting with gynecomastia, elevated estrogens, and hypogonadism, what clinical factors would push you to obtain testicular and/or adrenal imaging to rule out an estrogen-producing tumor?
It is not generally necessary or useful to measure serum estradiol in the evaluation of acute (tender and/or growing) gynecomastia. The widely available estradiol assays are generally immunoassays that are not accurate at the low estradiol concentrations in men. In addition, it is not uncommon to se...
