Recent and Emerging Therapies for Iron Deficiency in Anemia of CKD: A Review.

Iron deficiency commonly contributes to the anemia affecting individuals with chronic kidney disease. This review describes diagnostic criteria for iron deficiency in chronic kidney disease, as well as mechanisms of functional and absolute iron deficiency and general treatment principles as delineated in the KDIGO (Kidney Disease: Improving Global Outcomes) guideline. Repletion of absolute iron deficits has progressed over time with the addition of better tolerated, more effective oral agents, including ferric citrate, ferric maltol, and sucrosomial iron.
