This patient has chronic kidney disease, as indicated by elevated serum creatinine/BUN and evidence of anemia of chronic disease (normochromic normocytic). Poorly functioning kidneys do not hydroxylate 25-dihydroxycholecalciferol to 1,25-dihydroxycholecalciferol well nor produce adequate erythropoietin (hence the CKD-related anemia). Patientโs with CKD thus develop secondary hyperparathyroidism due to deranged phosphate excretion and inadequate Vitamin D activation resulting in hypocalcemia. Thus, we should expect to see low calcium, high phosphorus, low 1,25 vitamin D, and low Epo.
