Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
With isolated reticulocytopenia, the main cause is Parvovirus B19 infection of reticulocytes leading to transient anemia. [2] In patients who rely on frequent red cell regeneration e.g. sickle cell disease, a reticulocytopenia can lead to a severe anemia due to the cessation in red cell production (erythropoiesis), referred to as aplastic ...
Aplastic anemia [35] affects all kinds of blood cells. Fanconi anemia is a hereditary disorder or defect featuring aplastic anemia and various other abnormalities. Anemia of kidney failure [35] due to insufficient production of the hormone erythropoietin; Anemia of endocrine disease [36] Disturbance of proliferation and maturation of erythroblasts
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors , which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia due to bone marrow insufficiency.
It should increase within 2–3 days of a major acute hemorrhage, for instance, and reach its peak in 6–10 days. [3] If reticulocyte production is not raised in response to anemia, then the anemia may be due to an acute cause with insufficient time to compensate, or there is a defect with red blood cell production in the bone marrow.
It is characterized by anemia and reticulocytopenia and can be chronic or acute. [3] Diamond–Blackfan anemia is a type of PRCA that occurs at birth. PRCA can be acquired as a primary disorder or as a result of another disorder. [4] Immunosuppressive drugs, particularly corticosteroids, will usually result in a temporary or permanent remission.

Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are single-gene disorders and, in most cases, they are inherited as autosomal co-dominant traits.
