Not really, it didnt cause it, but made worse. I was always anemic or borderline most my life due to an inherent metabolic disorder. My anemia got really bad post treatment, usually hemoglobin is less than 10, and my creatinine was always 1.0 pre-treatment until I had kidney failure as a result of chemo via septic shock, sepsis. It's 2.3 now, new base level, but way down from 7. Although acute kidney failure, CKD, as you probably know, can cause disruption in the erthropotein sp making, so to some extent, yes.
