pertaining to, characterized by, or producing hemolysis.
hemolytic anemia anemia caused by the increased destruction of erythrocytes. A frequently fatal type occurs in infants as a result of Rh incompatibility with the mother's blood (see Rh factor and erythroblastosis fetalis). Other types result from mismatched blood transfusions; from industrial poisons such as benzene, trinitrotoluene (TNT), or aniline; and from hypersensitivity to certain antibiotics and tranquilizers (drug-induced hemolytic anemia). Another important cause is mechanical obstruction caused by microvascular or valvular abnormalities. In addition, it sometimes occurs as a result of a disorder of the immune response in which B-cell–produced antibodies fail to recognize the body's own erythrocytes and directly attack and destroy them (autoimmune hemolytic anemia). Finally, some types of hemolytic anemia appear in the course of other diseases such as leukemia, hodgkin's disease, other types of cancer, acute alcoholism, and liver diseases. Along with the usual symptoms of anemia, the patient may exhibit jaundice. If the cause of the condition can be determined, and if it can be successfully treated, there is a good chance of recovery. steroids and transfusion therapy are used to treat some types. In other cases, surgical removal of the spleen may bring about great improvement.
hemolytic disease of newborn erythroblastosis fetalis.
hemolytic jaundice a rare, chronic, and generally hereditary disease characterized by periods of excessive hemolysis due to abnormal fragility of the erythrocytes, which are small and spheroidal. It is accompanied by enlargement of the spleen and by jaundice. The hereditary form is also known as familial acholuric jaundice; there is also a rare acquired form. See also hyperbilirubinemia.
Destructive to blood cells, resulting in liberation of hemoglobin.
Referring to the destruction of the cell membranes of red blood cells, resulting in the release of hemoglobin from the damaged cell.
