REN and anemia: The guidelines suggest focusing on preserving renal function through the normalization of blood pressure and proteinuria with the use of inhibitors of the renin-angiotensin-aldosterone system, treating anemia with erythropoiesis stimulators, taking care of energy adequacy, including the use of an enteral tube or gastrostomy when necessary, correcting hydro-electrolytic and acid-base disturbances, controlling PTH levels in the target range of CKD, using recombinant GH when indicated, and early kidney transplantation with immunosuppression protocols with minimal doses of steroids30.
