Lots of Blood Disorders and Diseases

Posted by 24 December, 2008 (0) Comment

If you look up blood disorders and diseases in the dictionary you will find a lot of them to investigate. A blood disorder is a disease or disorder of the blood.

Cytopenia is a deficiency of the cellular element of the blood. There are many forms of cytopenia including anemia which is low red blood cells, leukopenia or neutropenia which is low white blood cell count and thrombocytopenia which is low platelet count, granulocytopenia which is low granulocyte count, and pancytopenia which is a low red blood cell count, low white blood cell count and low platelet counts.

Acidemia is a blood disorder that is characterized by an increase in the concentration of hydrogen ions in the blood. There is an abnormal acidity of the blood. Acidemia relates to the state of low blood pH.

Blood dyscrasia is any abnormal condition of the blood and can involve diseases of the blood-forming organs such as the bone marrow, spleen and liver. It is a pathological condition involving disorders on the cellular level within the blood. The patient experiences bleeding due to poor platelet formation or a decrease in amount of platelets, and also frequent infections.

Bleeding disorders involve problems with the clotting mechanisms of the blood. Clotting protects against excessive bleeding that may follow surgery, injury or trauma. Many blood-clotting factors (proteins) are involved in the complex process of blood coagulation. Bleeding problems can be mild or they can be severe. These factors, platelets and other substances must work together well in order for bleeding to stop. Fibrin, is a material that is formed when a clot is needed. Clotting blood disorders occur when there are defects in the coagulation system as a result of deficiencies in clotting factors, missing clotting factors, or a change in the platelet functionality. Defects in platelets can lead to bleeding after injury.

Other issues with blood disorders include blockage of vessels, blockage of lung arteries, blockage of renal vein, blood clots in the brain or legs, blood clots in the lungs.

Hypovolaemia is a blood disorder consisting of a decrease in circulating blood volume.

Leucocytosis is an abnormal increase in the number of white blood cells (WBCs) as a result of an infection.

Microcytosis is another blood disorder in which there is a presence of microcytes which are abnormally small red blood cells which can be associated with anemia.

As you can see there are lots of blood disorders and diseases. The above list is just barely scratching the surface. You can find more blood disorders and diseases in books, and Websites online. The more we understand about blood disorders and diseases the better we connect to the flow of blood that courses through our veins serving a very important role in all of our lives.

Getting to Know About Hemolytic Anemia

Posted by 24 December, 2008 (0) Comment

Are you curious about what hemolytic anemia is? Do you have the condition or does someone you know have it? Hemolytic anemia is a blood condition in which there are not enough red blood cells in the blood of the individual. Different things including an infection, or certain medications can cause the lack of enough red blood cells, autoimmune disorders can cause hemolytic anemia as well as other inherited disorders. There are various types of hemolytic anemia such as Sickle-cell anemia, paroxysmal nocturnal hemoglobinuria, hemolytic anemia due to G6PD deficiency, and hereditary elliptocytosis, spherocytosis, ovalocytosis, and also idiopathic autoimmune hemolytic anemia.

The symptoms of hemolytic anemia include having chills, being fatigued, having pale skin, and experiencing shortness of breath, or having a rapid heart rate. The individual may also have yellowed skin, dark urine or an enlarged spleen.

How do doctors diagnose hemolytic anemia?

There are various tests that can be conducted including some that are specific to hemolytic anemia such as looking for elevated indirect bilirubin levels, low serum haptoglobin, hemoglobin in the urine or hemosiderin in the urin, also an increased urine and fecal urobilinogen and an elevated absolute reticulocyte count. The individual will have a low red blood cell count and low hemoglobin as well as an elevated serum LDH. The doctor may also order a direct measurement of the red cell life span by radioactive tagging techniques, which will show a shortened life span for the red blood cells.

The doctor will have several goals when treating the patient with hemolytic anemia. The first goal is to reduce or stop the hemolysis of red blood cells. The second goal is to increase the red blood cell count as close to normal levels as possible. Lastly the doctor will want to treat any underlying cause.

Treatments are based on the type of hemolytic anemia the patient has, the cause for the anemia, and the severity of the hemolytic anemia. The treatment will also be based on age, and also the medical history.

If the doctor can isolate the underlying cause, the anemia may go away when the cause is treated.

Severe hemolytic anemia can be life threatening if it is not treated promptly.

Common treatments include blood transfusions, medications, lifestyle changes, and a treatment to remove antibodies from the red blood cells called, "plasmapheresis", surgery, and a bone marrow or stem cell transplant.

Medications used to treat hemolytic anemia:

If you have autoimmune hemolytic anemia (AIHA) you may be treated with corticosteroid medications, such as prednisone. If you need to suppress the immune system, medications such as azathioprine, cyclophosphamide, or danazol may also be prescribed.

Intravenous gamma globulin may als be prescribed to suppress antibody formation if the individual does not respond well to the corticosteroids.

If other treatments designed to effect the immune systme plasmapheresis may be tried. Plasmapheresis removes the antibodies from red blood cells.
