- Iron deficiency
- B12 (folic) deficiency
- Aplastic anemia
- Hypoplastic anemia
- Metaplastic anemia

- Aplastic anemia
- Dysplastic anemia
Posthemorrhagic Anemia
- Can be acute or chronic
- Acute posthemorrhagic anemia is normochromic and normocytic in the first hours after bleeding
- Restoration of plasma volume after acute blood loss causes temporary dilution of blood and decrease in hematocrit
- First sign of regeneration of red blood cells is reticulocytosis, which indicates activity of hemopoiesis
Chronic Posthemorrhagic Anemia
- Occurs with chronic hemorrhage and may be a symptom of gynecological, oncological, or gastrointestinal diseases
- Characterized by hypochromia, microcytosis, foci of regeneration in bone marrow of tubular bones, and presence of foci of extra-oesophageal hemopoiesis
- Changes caused by chronic hypoxia are also present
Hemolytic Anemia
- Characterized by shortening of life of red blood cells
- Classified based on three factors: cause of hemolysis, intra- or extravascular localization of hemolysis, and congenital or acquired character of the disease
Causes of Hemolytic Anemia
- Endoerythrocytic factors:
- Membranopathy: hereditary spherocytosis, elliptocytosis
- Fermentopathy: insufficiency of glucose-6-phosphate dehydrogenase, pyruvate kinase deficiency
- Hemoglobinopathy: disorders of globin chains, reduction of synthesis of globin chains (thalassemia)
- Acquired anemia: paroxysmal nocturnal hemoglobinuria
Anemias Caused by Exoerythrocyte Factors
- Autoimmune hemolytic anemia: warm thermal antibody, cold-blooded, anemia in autoimmune diseases
- Immune hemolytic anemia: hemolytic disease of newborns, transfusion hemolytic reaction, medicinal immune hemolytic anemia, hemolysis in response to toxins and chemicals
- Mechanical damage of erythrocytes: microangiopathic anemia (erythrocyte fragmentation syndrome)
- Anemia in infectious diseases: malaria
- Hyperplenism
- Mixed species
- Dyserythropoietic anemia
Classification of Anemias
-
Destruction of proliferation and differentiation of stem cells
- Aplastic anemia
- Aplasia of the erythroblastic sprout
- Anemia in renal insufficiency
- Anemia in endocrine disorders
-
Destruction of proliferation and differentiation of erythroblasts
-
Disruption of DNA synthesis
- Insufficiency or impairment of absorption of vitamin B12 and folic acid (megaloblastic anemia)
-
Destruction of the synthesis of Hb
- Violation of heme synthesis (Fe deficiency)
- Violation of globin synthesis (thalassemia)
-
Unknown or mixed mechanisms
- Anemia due to a violation of the metabolism of Fe (anemia sideroblast, with chronic diseases, with myelodysplasia)
-
Disruption of DNA synthesis
Characteristics of Megaloblastic Anemia
- Anisocytosis: macrocytes and megalocytes predominate
- Poikilocytosis: erythrocytes in the form of an oval, racket, crescent
- Megalocytes with remnants of the nucleus (Kebot's rings)
- Erythrocytes are brighter in color
- Atrophy of the gastric mucosa in pernicious Addison-Birmer anemia
- The mucous membrane of the stomach is thinned, there are only single glandular structures
- Atrophic gastritis precedes the development of gastric cancer (with pernicious anemia, stomach cancer develops 8 times more often)
