Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Hematologic diseases are disorders which primarily affect the blood.
Classification of hematologic diseases
Classification of hematologic diseases
- Hemoglobinopathies (congenital abnormality of the hemoglobin molecule or of the rate of hemoglobin synthesis)
- Anemias (lack of red blood cells or hemoglobin)
- Iron deficiency anemia
- Megaloblastic anemia
- Vitamin B12 deficiency
- Folate deficiency
- Hemolytic anemias (destruction of red blood cells)
- Genetic disorders of RBC membrane
- Genetic disorders of RBC metabolism
- Immune mediated hemolytic anaemia (direct Coombs test is positive)
- Autoimmune hemolytic anemia
- Warm antibody autoimmune hemolytic anemia
- Idiopathic
- Systemic lupus erythematosus (SLE)
- Evans’ syndrome (antiplatelet antibodies and haemolytic antibodies)
- Cold antibody autoimmune hemolytic anemia
- Warm antibody autoimmune hemolytic anemia
- Alloimmune hemolytic anemia
- Hemolytic disease of the newborn (HDN)
- Rh disease (Rh D)
- ABO hemolytic disease of the newborn
- Anti-Kell hemolytic disease of the newborn
- Rhesus c hemolytic disease of the newborn
- Rhesus E hemolytic disease of the newborn
- Other blood group incompatibility (RhC, Rhe, Kid, Duffy, MN, P and others)
- Hemolytic disease of the newborn (HDN)
- Drug induced immune mediated hemolytic anaemia
- Penicillin (high dose)
- Methyldopa
- Autoimmune hemolytic anemia
- Hemoglobinopathies (where these is an unstable or crystalline hemoglobin)
- Paroxysmal nocturnal hemoglobinuria (rare acquired clonal disorder of red blood cell surface proteins)
- Direct physical damage to RBCs
- Microangiopathic hemolytic anemia
- Secondary to artificial heart valve(s)
