What type of anemia occurs as a result of hemolytic uremic syndrome in children?

Hemolytic uremic syndrome (HUS) is characterized by three key features: hemolytic anemia, acute renal failure, and thrombocytopenia. The anemia observed in HUS is specifically a hemolytic anemia, which results from the destruction of red blood cells (RBCs). This destruction can be due to several factors associated with HUS, primarily the formation of small clots in the blood vessels that lead to mechanical injury of the red cells, as well as the activation of the immune system that can target RBCs.

In hemolytic anemia, the bone marrow responds to the increased destruction of red blood cells by increasing production. This often results in an elevated reticulocyte count, which reflects the marrow's response. In the context of HUS, the anemic state is acute and related directly to the breakdown of red cells.

Other classifications of anemia, such as macrocytic, microcytic, and normocytic anemia, refer to the size and shape of red blood cells rather than the underlying mechanism of their reduction. In contrast, hemolytic anemia directly captures the condition experienced in HUS, which is defined by increased destruction of erythrocytes. Therefore, this choice accurately describes the type of
