When do you recommend screening patients with T2DM for heart failure?
Heart failure is increasingly being recognized as a complication of diabetes. Heart failure is classified in 4 stages. Stage A is “at risk” because of diabetes, stage B is asymptomatic for the patient but with detectable cardiac abnormalities and then stage C and D are symptomatic stages of heart fa...
Do you have any specific recommendations to prevent large fluctuations in sodium levels during a colonoscopy prep in patients with central diabetes insipidus on DDAVP?
Interesting, I have just received a message from a patient in this very same situation. I am not aware of any specific literature on this. In absence of such data, I usually recommend remaining on the same desmopressin dose and obeying to thirst, as I worry about hyponatremia that may be caused by a...
In postmenopausal osteoporosis, would you switch to romosozumab (rather than a PTH/PTHrP analog) if a patient fractures while on denosumab?
This is an interesting question because it raises the subject of how one defines "treatment failure" among patients who are using bone-strengthening medications. I remind patients that our drugs are most effective at preventing spinal fractures with efficacy that can exceed 70% relative risk reducti...
Is azilsartan superior to other angiotension receptor blockers in regard to cardiorenal outcome data?
In short, there are no data. There are very few head-to-head comparisons of ARBs on hard outcomes. Azilsartan was used in SPRINT (alongside losartan and valsartan), though the secondary analyses focused on class effect as opposed to specific med-to-med comparisons within a class (DeCarolis et al., P...
Is it safe to discontinue prenatal vitamins that contain biotin for a few days during pregnancy when labs in particular thyroid tests are planned for treating hypo or hyperthyroidism in pregnancy?
Biotin doses of 5-10 mg can impact TFTs. Most prenatal vitamins contain 30-35 mcg of biotin (although there are some that contain up to 500 mcg of biotin). This is usually too low to cause assay interference, so I do not recommend cessation of prenatal vitamins prior to TFTs (although I will ask tha...
Is the accuracy of continuous glucose monitors (DEXCOM or Libre) lower in patients undergoing dialysis?
The question of the accuracy of CGM in dialysis patients is an important one and has been debated for some time. CGM is a superior method for glucose management over fingersticks in most clinical settings. Patients with ESRD on dialysis in particular, can have very difficult-to-control diabetes. A r...
For patients on peritoneal dialysis with type 2 diabetes mellitus, do you have a preferred long- acting insulin and time of insulin administration?
Insulin management in patients on peritoneal dialysis can be tricky. In my experience, you have to be very cautious with long-acting insulin. Much of the hyperglycemia occurs during the exchanges with the dextrose solution. Therefore, using long-acting insulin can cause hypoglycemia. My suggestion i...
Are there any concerns with live vaccine innoculation and patients who are on denosumab?
This is a complicated question because while denosumab is a biologic therapeutic that has immunomodulatory effects on innate and adaptive immunity its association with serious infections complications appears modest. An increased rate of background infections and some increase in serious infections ...
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.
Do you routinely check vitamin K levels in post-bariatric surgery patients?
Vitamin K levels are not checked routinely in post-bariatric surgery patients. Deficiency of this vitamin is very uncommon in patients who have undergone a sleeve gastrectomy and even with Roux-en-Y gastric bypass. There is more potential for deficiency in patients who have had biliopancreatic diver...
