[Anemia and iron deficiency in the elderly. Prevalence, diagnostics and new therapeutic options].

The prevalence of anemia in geriatric patients is high. With some variation in different patient cohorts, prevalence of anemia can reach 40%. Anemia is not an age-related disease on its own, but is a symptom with multifactorial genesis and high risk potential. It directly influences mortality, morbidity, and the rate of hospitalization, particularly in older patients suffering from chronic heart failure or chronic kidney disease. The high prevalence of anemia in chronic kidney disease is explained by a combination of erythropoietin and iron deficiency. This review summarizes the recommendations of the iron symposium at the 2010 German Geriatric Society Meeting in Potsdam, Germany. It intends to provide current information on prevalence, diagnostic work-up, and therapeutic options for anemia in the rapidly growing group of elderly patients.
