#AspenKidney Preservative management of CKD: life sustaining conservative management, delay dialysis by pharmacological and modifying diet and lifestyle.
He says even though we closed the book (MDRD study) on low protein diet 30 years ago we are reopening the book.
low protein 0.6 to 0.8 g/kg
Very low protein diet 0.3 g/kg
Showing Tuttle data showing GFR skyrocketing to 165 ml/min after amino acid infusion. nejm.org/doi/full/10.10…
This explains the acute drop in GFR when patients switch to low protein diet. This is an acute hemodynamics effect and should be ignored in long term outcome (as we do in the SGLT2i studies) He says if you ignore this in MDRD the study becomes positive. #AspenKidney
Kam has all of his patients do regular 24 hour urine to monitor K, Na, and dietary protein. Urine urea nitrogen to protein intake calculator is here: nephron.org/nephsites/nic/…#AspenKidney
Lang based diet to improve mortality in CKD. #AspenKidney

Next up Mats Wahlstrom on The Next Generation of Dialysis. Former CEO of Fresenius and Gambro. #AspenKidney
We are seeing a major investment in home therapies. Credits government initiatives. We are currently at 2% home hemo and 10% PD. #AspenKidney
He credits NextStage as putting home hemo back on the map. Small. Portable. Easy to use. Online dialysat4e production. Major driver of success: Capturing commercial payers! #AspenKidney
Next up Isaac Teitelbaum on Delivering High Quality Peritoneal Dialysis: What Really Matters? #AspenKidney
Teitelbaum measures Kt/V and then ignores it. He starts by focusing on the poor quality of V in the equation. 95% CI will range Kt/V from 1.44 to 1.94 (and that is using bioimpedence) #AspenKidney
If you use anthropomorphic formulas (which we all do) will be off ±20% Think Kt/V ranging from 1.44 to 2.06 #AspenKidney
Next up at #AspenKidney is Jessica Kendrick fellowship PD to talk about CKD and Acid-Base Disorders
Metabolic acidosis, defined as HCO3 < 22, is found in 20% of stage 4 CKD. #AspenKidney
Ammonia is responsible for most of the renal adaption to metabolic acidosis. Requires proximal tubule function. Becomes problematic as GFR falls below 45. #AspenKidney
Kicking off the 47th Annual Course on Renal Disease and Electrolyte Disorders (I am declaring the hashtag to be #AspenKidney) is @kamkalantar with a talk on incremental dialysis.
Recognizing that we are 2 years away from 50 year mark from @dick_nixon expanding chronic dialysis to all Americans. 50 Years! Wow. #AspenKidney
Starting dialysis is marked by high mortality, high cost. #AspenKidney
In Matrix randomizing patients to femoral or radial caths resulted less CIN/CAN with radial approach. No difference in contrast.

As a blogger, I always want more words for everything. I want to luxuriate in as many ways to say kidney as possible. If Eskimos have 50 ways to say snow (and it's over 50), nephrologists should have at least a dozen ways to say kidney.
But what I want is separate from the question of what should we do.
For a long time nephrology projected an aura of mastery. We understood the chemistry of the body better than any other doctor. We jelously hoarded that knowledge behind walls of complexity.
