Injured kidneys may be lashing out, releasing substances that cause systemic effects contributing to mortality. These substances are unique from substances that accumulate with zero GFR.
She compared ischemic model of AKI (clamp and release) to bilateral nephrectomy.
Initial theory of mediator was cytokines. IL-6 quartile predict mortality. #AspenKidney
Faubel says IL 6 goes up with all stress. Happened with ischemic and nephrectomy model. #AspenKidney
Lung injury is mediated by IL-6 and kidney injury. All methods that inhibit IL-6 reduce lung injury #AspenKidney
Fluid removal does not correct pulmonary edema due to capillary leak. #AspenKidney
What dialysis can fix and what it cannot fix. #AspenKidney
Faubel says the answer to everything is metabolomics. Screen for small molecules (less than 2000 daltons). Only costs $60 per sample. There generate tons of data. #AspenKidney
AKI and the heart: mitochondria are not normal so function is not normal. #AspenKidney
The metabolomic study shows decreased amino acids in the heart in AKI. Aspartame and glutamate are decreased in bypass and cardioplegia solutions are supplemented with these to correct this. (May have gotten this wrong) #AspenKidney
She did mouse echocardiograms in mice with AKI. Mice have diastolic dysfunction and this persists for a year after recovery of AKI. Humans have similar increased risk of CHF after AKI #AspenKidney
Fall in ATP in the heart with mouse AKI #AspenKidney
Next up is @doc_faubel again for a lit review in AKI. She starts out saying that she will not be able to go over all 68,000 articles in pubmed on the topic. Also nice shout out to #NephJC
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
#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
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
