Причины анемий

(from Wintrobe's Clinical Hematology)
-------------------------------------

Classification of the Normocytic Anemias

--------------------------------------------------------------------------

Anemia associated with appropriately increased erythrocyte production
Posthemorrhagic anemia
Hemolytic anemia

Decreased erythropoietin secretion
Impaired source
>Renal: anemia of renal insufficiency
>Hepatic: anemia of liver disease
Reduced stimulus (decreased tissue oxygen needs)
>Anemia of endocrine deficiency
Protein-calorie malnutrition
Anemia of chronic disorders

Anemia with impaired marrow response
Bone marrow hypoplasia
Red blood cell aplasia
>Acquired pure red cell aplasia in adults
>Transient erythroblastopenia of childhood
>Transient aplastic crises associated with hemolysis
Aplastic anemia (pancytopenia)
Bone marrow infiltrative disorders
Leukemia
Myeloma
Other myelophthisic anemias
Myelodysplastic anemias
Dyserythropoietic anemias (congenital dyserythropoietic anemia type II)
Iron deficiency (early)

Classification of Microcytic Anemias

--------------------------------------------------------------------------

Disorders of iron metabolism
Iron deficiency anemia
Anemia of chronic disorders

Disorders of globin synthesis
Alpha and beta thalassemias
Hemoglobin E syndromes (AE, EE, E-beta-thalassemia)
Hemoglobin C syndromes (AC, CC)
Unstable hemoglobin disease

Sideroblastic anemias
Hereditary sideroblastic anemia
>X-linked
>Autosomal
Acquired sideroblastic anemia
>Refractory anemia with ringed sideroblasts
>Malignancies
>Myeloproliferative disorders
Reversible acquired sideroblastic anemia
>Alcoholism
>Drugs (isoniazid, chloramphenicol)
Lead intoxication (usually normocytic)
