Test tube kidneys?

While I'm sure that Miromatrix would shudder at my description, it looks like they're developing the equivalent of a test tube kidney which could be used for transplant.

While the science and bioengineering behind it is extremely complex, this is how I understand it.

Miromatrix uses decellularization and recellularization technology to create a transplantable kidney.

 Huh?

 They take an dead organ - it doesn't even need to be human - and using detergents (I'm guessing they're stronger than Dawn ;-) ) they strip away all the cells. What remains is the kidney's extracellular matrix (collagen, enzymes and glycoproteins) and all its chemical cues. Then the "generic" organ is repopulated with the transplant candidate's cells, eliminating the risk it will be rejected upon implantation.

 Early studies have shown that it takes from four to eight days to culture the transplantable kidney and, even better, the new organ produces urine when tested.

 Because a PKD patient's genetic material is fubar'd, I'm guessing this approach would not work. But there have got to be ways around that (possible genetic modification of cells to eliminate the PK1/PK2 gene? or use of closely matched genetic material? or... I'll leave it up to the experts).

 Regardless, it's an exciting time for someone with CKD. I can't wait to see what the future holds for innovative developments in the treatment of CKD/PKD.

Artificial kidney

I have a somewhat fanciful thought of what an artificial kidney would look like. I see a device that is shaped like a kidney (of course) but is completely clear so you could see all the blood circulating through it. Granted, once it's implanted no one's going to see it but - hey - it's my vision. The closest picture I can find of what's in my mind's eye is this image. Granted, that's a picture of a kidney-shaped paper weight and it's a little cloudy, but I know you can picture it too. My, oh my. My imagination is not even close to reality. According to a post from the American Journal of Kidney Diseases , there are three new approaches being explored right now: the automated wearable artificial kidney ('AWAK'), the wearable artificial kidney ('WAK') and the implantable artificial kidney ('IAK'). My money's on the IAK and you'll understand why once I show you the concept pictures of the other two. The AWAK is said to ...

Oops I did it again

Oops! I advocated for myself again. After getting the results from my latest CBC (Complete Blood Count), my doctor put me on daily Vitamin D-3 to increase levels but did not recommend iron supplementation for (what I consider) borderline anemia. I was glad to hear low Vitamin D might be adding to increased fatigue but I still wondered... I have a history of low Ferritin levels, despite sufficient RBC/hemoglobin counts. So... I made an appointment with an independent lab and had them check my iron levels. Results? My Ferritin level is at 51, well within the 'normal' range of 100-232. Still, I wondered... So I did further research. My low Ferritin level was originally discovered when I was diagnosed with Restless Leg Syndrome (but I may actually have Periodic Limb Movement Disorder). So I looked up literature regarding recommended Ferritin levels given RLS/PLMD. Huh. Treatment recommendations are that Ferritin be no lower than 75 for people with RLS/PLMD. Bingo! ...
