Why would the adaptive, compensatory mechanisms that protect phosphate and calcium homeostasis have such ultimately devastating consequences for these patients? Tight control of both phosphate and calcium homeostasis is essential to the normal functioning of virtually all life-sustaining, physiologic processes. Cell phosphate is at the core of all energy-dependent physiologic processes. Cell calcium and its ubiquitous binding protein are the triggers that initiate virtually all cellular functions. Thus, compromising the tight regulation of these two ions, even short term, carries an immediate risk to the highly integrated physiologic systems that are critical to sustaining essentially all biologic process. Viewed in that context, a trade-off that maintains biologic systems for years but ultimately leads to life-threatening conditions later in patients with CKD and ESRD is understandable.Unfortunately for the patient with early CKD, these adaptive mechanisms are so successful that even though GFR is significantly compromised, serum phosphate does not become elevated until the late stages of renal disease, at which time health care providers recognize the need to respond. By that time, parathyroid hyperplasia is irreversible, bone loss is significant, and soft tissue calcification, even if not grossly evident, is already well established.
I'm curious to hear what your experiences have been with itchy skin? What did it feel like when you started getting it? Were you pre-D? Is it the toxic buildup? Were you itchier at certain times of the day/night? Also, my face is starting to break out, I'm reminding me of my teenage self, not in a good way. Do you suppose that could be from the toxic buildup? anybody else get acne once kidney function got low?
