Hematologic disease

Hematologic diseases are disorders which primarily affect the blood & blood-forming organs. Hematologic diseases include rare genetic disorders, anemia, HIV, sickle cell disease & complications from chemotherapy or transfusions. Hemoglobinopathies (congenital abnormality of the hemoglobin molecule or of the rate of hemoglobin synthesis) Sickle cell disease Thalassemia Methemoglobinemia Anemias (lack of red blood cells or hemoglobin) Iron-deficiency anemia Megaloblastic anemia Vitamin B12 deficiency Pernicious anemia Folate deficiency Hemolytic anemias (destruction of red blood cells) Genetic disorders of RBC membrane Hereditary spherocytosis Hereditary elliptocytosis Congenital dyserythropoietic anemia Genetic disorders of RBC metabolism Glucose-6-phosphate dehydrogenase deficiency (G6PD) Pyruvate kinase deficiency Immune mediated hemolytic anemia (direct Coombs test is positive) Autoimmune hemolytic anemia Warm antibody autoimmune hemolytic anemia Idiopathic Systemic lupus erythematosus (SLE) Evans syndrome (antiplatelet antibodies and hemolytic antibodies) Cold autoimmune hemolytic anemia Cold agglutinin disease Paroxysmal cold hemoglobinuria (rare) Infectious mononucleosis 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) Drug induced immune mediated hemolytic anemia Penicillin (high dose) Methyldopa 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) Aplastic anemia Fanconi anemia Diamond–Blackfan anemia (inherited pure red cell aplasia) Acquired pure red cell aplasia Decreased numbers of cells Myelodysplastic syndr
