Anemia aplástica, f
|
aplastic anemia
def. Anemia due to failure of the bone marrow to produce blood cells, including red and white blood cells as well as platelets. It frequently occurs without a known cause. Known causes include exposure to chemicals (benzene, toluene in glues, insecticides, solvents), drugs (chemotherapy, gold, seizure medications, antibiotics, and others), viruses (HIV, Epstein-Barr), radiation, immune conditions (systemic lupus erythematosus, rheumatoid arthritis), pregnancy, paroxysmal nocturnal hemoglobinuria, and inherited disorders (Fanconi's anemia).

Sickle cell anemia |

Anemia ferropriva, f
|
iron deficiency anemia
def. The most common known form of nutritional disorder in the world, iron deficiency results in anemia because iron is necessary to make hemoglobin, key molecule in red blood cells responsible for the transport of oxygen. In iron deficiency anemia, the red cells appear abnormal and are unusually small (microcytic) and pale (hypochromic). The pallor of the red cells reflects their low hemoglobin content.

|
Anemia hemolítica, f
|
hemolytic anemia
def. Anemia due to the destruction (rather than underproduction) of red blood cells.

anemia hemolítica auto-imune

Autoimmune hemolytic anemia |
|
Anemia hemolítica por anticorpos «frios», f
|
cold antibody hemolytic anemia
def. the autoantibodies become most active and attack red blood cells only at temperatures well below normal body temperature.
|
|
Anemia hemolítica por anticorpos «quentes», f
|
warm antibody hemolytic anemia
def. autoantibodies attach to and destroy red blood cells at temperatures equal to or in excess of normal body temperature

Anemia macrocítica

macrocytic anemia |
|
Anemia megaloblástica, f
|
megaloblastic anemia
def. A disorder characterized by the presence of anemia, abnormally large red blood cells (megalocytes or macrocytes), and megaloblasts

Hemoglobina, f, s
|
Hemoglobin, s
def. The oxygen-carrying pigment and predominant protein in the red blood cells . It forms an unstable, reversible bond with oxygen. In its oxygenated state it is called oxyhemoglobin and is bright red. In the reduced state it is called deoxyhemoglobin and is purple-blue.

Hemorragia, f, s

Hemorrhage, s
def. Bleeding or escape of blood from a vessel.

Medula óssea, f, Meduka ósseas
|
bone marrow, bone morrows
def. The soft blood-forming tissue that fills the cavities of bones and contains fat and immature and mature blood cells, including white blood cells, red blood cells, and platelets. Diseases or drugs that affect the bone marrow can affect the total counts of these cells.

Reacção auto-imune, f

Autoimmune reaction |
|
Talassemia, f, s
|
thalassaemia, s
def. Not just one disease but rather a complex series of genetic (inherited) disorders all of which involve underproduction of hemoglobin, the indispensable molecule in red blood cells that carries oxygen. The globin part of hemoglobin is made up of 4 polypeptide chains (usually 2 chains of one type and 2 chains of another type of chain). In thalassemia, there is a mutation (change) in one of the types of globin chains. Depending upon which globin chain is affected, the mutation typically leads to underproduction (or absence) of that globin chain, a deficiency of hemoglobin, and anemia.
