Anémie et médicaments

Abstract

The onset of one or several episodes of anemia during the course of an individual's lifetime is highly common. At times undetected, at other times symptomatic, these episodes are rarely severe. Highly diverse mechanisms can be involved. Often the cause of anemia is obvious; sometimes explorations are needed to detect the cause. When a patient is taking medications, this cause should be suspected. The hemogram, particularly the changes in erythrocyte constants over time, can generally identify the causal mechanism and identify when these changes began. In patients taking several medications, who often have several interconnected pathologies, it can sometimes be extremely difficult to identify the cause of anemia. Knowing these causes related to medications and their mechanism can in some cases rule out unnecessary tests. The article provides an exhaustive review of anemia caused by medications: acute hemorrhagic anemia, anemia caused by plasma volume dilution or expansion, chronic depletion, deficiency anemia, anemia resulting from blockage of cell multiplication, anemia caused by inhibition of erythropoietin, anemia caused by hemapoietic stem cell immunoallergic reaction, hemolytic anemia of the hemapoietic stem cell, immune hemolytic anemia, corpuscular hemolytic anemia, mechanical anemia.
