Question for #nephsky #askrenal. Friend found these casts in a patient with multiple myeloma- Cr 0.8 and UPCR 0.1 g/g. They don’t look like typical hyaline casts. Any thoughts? @juancarlosqvelez.bsky.social @jrseltzer.bsky.social

My first attempt at suspending objects (a hard-boiled egg) in jello! Kidney biopsy simulation with our enthusiastic @uwnephrology.bsky.social first-year fellows. @nephsky.bsky.social

Here’s Matt’s data from 2012 to 2013. 18% for a decline in eGFR, 6% for hyperkalemia though this was before the publication of the new K-binder trials. All patients were under the care of a UW nephrologist, so my guess is that the general population % is ⬆️. pmc.ncbi.nlm.nih.gov/articles/PMC...

Here's some of the math with references. Even for someone with fixed ventilation, PCO2 returns to normal pretty rapidly.

📟 Consulted a few times last week for, “Is this an RTA?” and my knee-jerk answer is “No”.
📖 The truth is that RTAs are rare though we talk about them a lot in med school. So here are some causes of a non-gap acidosis that are more common than an RTA. A 🧵

I’ve never seen them either. Pt with a significant stone burden, pH 7.5 but from an ileal conduit. This one looked coffin-lid like?

Are these triangles triple phosphate crystals? There were some coffin lids mixed in. @weddellite.bsky.social @juancarlosqvelez.bsky.social @jrseltzer.bsky.social

Unfortunately, no also. The PTH rises early in CKD (see figure), but it isn’t specific. Plain old 25-OH vitamin D deficiency can raise the PTH, and PTH is much more sensitive to changes in calcium than it is to 1,25-OH vit D.

Important to note what “low” really means. In the 65 trial the low arm achieved a MAP around 68.

❌ But this is wrong, and the electrolyte free H2O clearance proves it. The UNa was 70 mEq/L and UK 30 mEq/L. So the serum sodium of 150 was greater than (UNa + UK) suggesting that there was excess free H2O excretion.

In both cases, the serum Na was 150 mEq/L and serum Osm (320 mOsm/L) was less than Uosm (350 mOsm/L).
This suggests that the urine was more concentrated than the blood, and therefore excess free water excretion was not the cause of hypernatremia.
