Diagnostic and therapeutic approach to anemia caused by chronic renal failure

Introduction: chronic kidney failure is a disorder in which kidney functions decrease progressively and irreversibly. Due to this decrease, the kidneys lose their ability to eliminate waste, concentrate urine, and maintain adequate levels of electrolytes in the blood. Objective: to update knowledge for the establishment of early diagnosis in the treatment of anemia in patients with chronic renal failure Method: a bibliographic search of scientific articles and information was carried out in the MEDLINE, Scopus, Redalyc and Latindex databases, to In turn, it is complemented with medical literature found on digital platforms such as Google Scholar. Of 68 articles identified, 16 publications were selected that met the inclusion, exclusion and PRISMA Statement criteria. Results: the diagnosis of anemia should focus on the blood count, reticulocytes, iron status, vitamin B12 and folic acid, while therapy is based on the use of iron, erythropoiesis-stimulating agents and in certain cases erythropoietin. Conclusions: providing early and optimal treatment to patients with chronic renal failure reduces the risk of developing hypoproliferative normocytic normochromic anemia.
