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 ...
How would you counsel a patient with CKD Stage 5 and prediabetes who is concerned about their risk of developing diabetes if they start peritoneal dialysis?
History of diabetes is certainly an important consideration to have when providing dialysis education to patients with advanced CKD. We don't contraindicate any modality, including peritoneal dialysis, when patients have a history of prediabetes or diabetes. However, I will acknowledge that uncontro...
What is your approach to treating IgA nephropathy in patients who also have IgA vasculitis?
In a patient with known IgA Vasculitis [IgAV], IgA dominant pattern of injury in the kidney biopsy reflects IgA Vasculitis with Nephritis [IgAV-N]. Thus, it would not be appropriate to call it IgA nephropathy [IgAN] in IgAV. Though the histological features in IgAN and IgAV-N can be common in the ki...
Do you recommend scheduled potassium phosphate dosing during PIRRT to avoid hypophosphatemia in patients with acute kidney injury requiring renal replacement therapy?
I would only do this once it has been documented that the patient developed hypophosphatemia with PIRRT. If hyperphosphatemic to start, certainly not.
What is your approach to management of tremors in a kidney transplant recipient who is taking a CNI for immunosuppression?
This can be a really vesing problem for patients. My approach is somewhat dependent upon the severity of the tremors. I will sometimes try some low dose propranolol, 10 mg po BID-TID, or more often I will try converting from a the shorting acting forms of tacrolimus (Q12 hour formulations) to the lo...
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 ...
In patients with lupus nephritis, and MAHA with positive anti-phospholipid autoantibodies, what are the considerations to use or not use anti-coagulation therapy?
I support anticoagulation and C5 inhibition for such patients if they are not adequately responding.
Is the combination of SGLT2i and GLP 1 R agonist therapy contraindicated in patients who develop an episode of euglycemic DKA?
Therapy always needs to be individualized, but in most cases, SGLT2 inhibitors should be stopped in patients who have had euglycemic DKA. Such individuals likely have low endogenous insulin production. GLP1R agonists could further increase the risk of recurrent euglycemic DKA, and I agree with Mehta...
Does vitamin D supplementation in primary hyperparathyroidism increase the risk of kidney stones?
Hyperparathyroidism does increase the risk of developing kidney stones. A study in New England Journal of Medicine, Broadus et al., PMID 7351950, reported that patients with elevated concentrations of 1,25-dihydroxyvitamin D are at increased risk for kidney stones. The reason is that 1,25-dihydroxyv...
What is your systolic blood pressure target for patients over 80 with frailty and multiple comorbidities?
The target of 150/90 mmHg for adults over 80 primarily comes from the HYVET study, which demonstrated benefit in reducing stroke and mortality in this age group. However, as with all decisions in geriatric care, treatment should be individualized and guided by the patient’s functional status and goa...
