When should you consider adding clonidine to an antihypertensive regimen for patients with advanced CKD?
Clonidine patch is useful in severely uncontrolled hypertension. In patients with CKD, not responding to conventional medications - like calcium blockers. Though the side effect profile is not great, it is less expensive and practical.
In patients with iron deficiency due to history of gastric bypass or IBD, would you consider oral iron therapy if the iron deficiency anemia is mild?
Oral iron can often be effective in iron deficiency, as long as absorption is intact. If you are concerned about absorption, performing an oral iron challenge can be useful in allowing you to avoid long trials of oral iron that will be ineffective. Simply check an iron panel at baseline, then admini...
How do you approach checking an aldosterone to renin ratio in an outpatient with hypertension and hypokalemia that is difficult to correct with oral potassium replacement?
It is well known that hypokalemia can affect the aldosterone-renin ratio (ARR). Since hypokalemia directly inhibits aldosterone production, this can lead to false negative results when using ARR to screen for primary aldosteronism. If it is difficult to correct hypokalemia with oral potassium repla...
In adults ≥80 years with TSH 6–10 mIU/L and minimal symptoms, do you initiate levothyroxine, monitor, or avoid treatment entirely?
I tend to check free T4 in this situation. Aging is associated with some elevation in TSH value up to 10 mIU/L with normal free T4, and in those patients, levothyroxine is not needed. In some patients, I have seen it rise above 10 with normal free T4. Supplementing levothyroxine to lower serum TSH w...
Would you consider a history of pancreatitis an indication for parathyroidectomy in patients with mild hypercalcemia secondary to primary hyperparathyroidism?
The association of pancreatitis with primary hyperparathyroidism (PHPT) has been a classic one, although an uncommon complication of PHPT. Studies vary in reporting an incidence of pancreatitis between 4-16% in patients with PHPT (usually single institution consecutive series). I think most people f...
When treating osteoporosis, does your duration of maintenance bisphosphonate therapy post anabolic therapy with PTH analogue change based on C-telopeptide levels?
I have treated many patients with teriparatide and conducted non-clinical studies on PTH/PTHrP receptors. Despite the fact that there are no PTH/PTHrP receptors on osteoclasts, when PTH stimulates osteoblast activity, the normal coupling via osteoprotegerin is intact, and about 4 weeks after one det...
How do we decide between Gallium-DOTATATE PET/CT and MIBG scans when evaluating a patient for suspected pheochromocytoma?
Mostly availability and feasibility. Gallium-DOTATATE is very sensitive.
What should the LDL target be in patients with prediabetes and high lipoprotein (a) with family history of coronary artery disease?
I don’t think that using Lp(a) to guide treatment is quite ready for prime time yet. It’s an independent predictor of risk compared to the rest of the lipid panel, but as far as I am aware, we do not yet have data that treating people based on it makes a difference. What I may do in this scenario is...
Do you initiate a GLP-1 receptor agonist as first-line pharmacotherapy ahead of metformin in a patient with newly diagnosed type 2 diabetes and a BMI above 35?
Yes
Would the diagnostic yield for ABIs or peripheral arterial duplex doppler in a patient with metal rods in both legs be similar or acceptable in comparison to those tests in a patient without metal rods?
Ankle-brachial index(ABI) relies on the compression of upper and lower extremity arteries with blood pressure cuffs and measuring the ratio of blood pressure between them. While I am not aware of specific studies in those with metallic rod fixation, ABI measurements should have similar utility as lo...
