What is the clinical significance of a paradoxical decrease in HDL cholesterol after starting statin therapy?

Whether HDL goes up, goes down or stay stable on statin therapy is honestly not of much concern to me. I do not think it is of any clinical significance since we know that statin therapy improves outcomes. In fact, studies show that the clinical benefit of statins is even stronger in individuals wit...

Are there specific populations with hypothyroidism for whom you would consider adding liothyronine to levothyroxine therapy, given observational data linking levothyroxine therapy alone to higher risks of dementia and mortality?

At this time, there is not enough evidence to routinely add T3 to Levothyroxine for the treatment of Hypothyroidism. Although there is the observational study mentioned above, the authors themselves have stated that further studies are needed to confirm the cognitive and mortality benefits of adding...

The peak cortisol value after 250 μg cosyntropin changes a little based on when it is done. We see a bigger delta cortisol if it is done in the afternoon. One may omit the baseline cortisol to cut back on costs or if there is a time constraint (avoiding going to the lab and then coming back for an i...

Do you recommend checking plasma metanephrine levels during adrenal venous sampling to assist in assessing lateralization in primary aldosteronism?

I have not concluded yet that the measurement helps with lateralization. At this point, the best use of measuring plasma metanephrines or androstenedione in patients with hypercortisolism and bilateral adrenal pathology is to confirm accurate adrenal vein catheterization. In my opinion, the literatu...

In such a case, the prolactin may decrease on its own, so I would wait to start a dopamine agonist and check for other pituitary hormone deficiencies and monitor prolactin every 2-3 months.

Yes. It would be a waste of time and money. Can go straight to using spironolactone or other mineralocorticoid blocker.

Metabolic dysfunction-associated steatotic liver disease (MASLD) can be found in about 30% of adults in the U.S. Diabetes is a significant co-morbidity and increases the risk of progression to metabolic dysfunction-associated steatohepatitis (MASH). I calculate a FIB-4 index in these patients to see...

Usually, less than 50, rarely 50-100. If it is higher than 100, one should look for another cause of hyperprolactinemia.

In patients using a tandem insulin pump on auto-mode/Control-IQ, would decreasing the basal settings on the profile actually reduce the delivered hourly insulin dose or is that only relevant if they switch to manual mode?

In the control IQ, the basal adjustment IS relevant in Auto-mode. The algorithm uses predicted CGM reading in 30 minutes (in the future) and responds to keep the glucose by CGM in the targeted range. See below: Above 160 mg/dL, basal insulin rate increases Above 180 mg/dL, a correction bolus is giv...
