Acute posthemorrhagic anemia or acute blood loss anemia is a condition in which a person quickly loses a large volume of circulating hemoglobin. Acute blood loss is usually associated with an incident of trauma or a severe injury resulting in a large loss of blood.
Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare autosomal recessive bone marrow failure syndrome characterized by severe thrombocytopenia, which can progress to aplastic anemia and leukemia. [4] CAMT usually manifests as thrombocytopenia in the initial month of life or in the fetal phase.
This is a shortened version of the fourth chapter of the ICD-9: Diseases of the Blood and Blood-forming Organs. It covers ICD codes 280 to 289 . The full chapter can be found on pages 167 to 175 of Volume 1, which contains all (sub)categories of the ICD-9.
Diamond-Blackfan Anemia is an example of a congenital bone marrow failure syndrome that primarily affects red blood cell production. In DBA, the erythroid cell lineage is more susceptible to cell death due to abnormal ribosome function. [4] This leads to a reduced population of red blood cell precursors and a resulting reticulocytopenia and anemia.
This is a life-threatening disorder that is a characteristic of aplastic anemia. [3] There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells.
Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
Anemia of prematurity (AOP) refers to a form of anemia affecting preterm infants [1] with decreased hematocrit. [2] AOP is a normochromic, normocytic hypoproliferative anemia. The primary mechanism of AOP is a decrease in erythropoietin (EPO), a red blood cell growth factor.
Congenital dyserythropoietic anemia (CDA) is a rare blood disorder, similar to the thalassemias. CDA is one of many types of anemia , characterized by ineffective erythropoiesis , and resulting from a decrease in the number of red blood cells (RBCs) in the body and a less than normal quantity of hemoglobin in the blood.
