Study Notes

Classification of Anemia

Anemia can be classified based on etiology into three main categories: blood loss, inadequate red blood cell production, and increased red blood cell destruction

Consequences of Anemia

The main consequence of anemia is a decrease in oxygen delivery to tissues, leading to tissue hypoxia

Hemolytic Disease of the Newborn

Hemolytic disease of the newborn is a condition characterized by severe anemia due to incompatible blood types between the mother and the baby

Megaloblastic Anemia

Megaloblastic anemia is a disorder characterized by the presence of abnormally large and immature red blood cells

Acute Blood Loss Anemia

The main clinical feature of acute blood loss anemia is hypovolemic shock

Nutritional Deficiency

Iron deficiency is the most common form of nutritional deficiency worldwide

Thrombotic Thrombocytopenic Purpura (TTP)

TTP is a condition that causes abnormal blood clot formation throughout small blood vessels, leading to low platelet levels, potential organ damage, and anemia

Spherocytosis

Hereditary spherocytosis is a genetic disorder that results in red cells that are spheroidal, less deformable, and vulnerable to destruction

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia is a disorder characterized by accelerated destruction of red cells

Chronic Inflammatory Disorders

Chronic inflammatory disorders disrupt the normal regulation of iron metabolism and contribute to anemia

Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency

The primary defect in G6PD deficiency is an impaired ability to generate NADPH, making red cells vulnerable to injury by oxidants

Aplastic Anemia

Aplastic anemia is a disorder in which the bone marrow fails to produce enough blood cells, including red blood cells, white blood cells, and platelets

α-Thalassemia and ß-Thalassemia

Thalassemia is a genetic disorder caused by mutations that decrease the rate of synthesis of α- or ß-globin chains
