Anemia aplastic

Description of aplastic anemia

Апластическая анемия – незаразная болезнь, which occurs, where the bone marrow stops producing blood cells. Bone marrow is red, spongy, internal part of the bone and is responsible for producing blood cells: red blood cells (erythrocyte), that deliver oxygen to all parts of the body, white blood cells (leukocytes), that protect the body from germs, and platelets, necessary for blood clotting. This disease can affect anyone, irrespective of age, race or sex.

Aplasticheskaya anemia, usually, occurs under the influence of environmental factors. In very rare cases, aplastic anemia can be hereditary.

The severity of the disease can vary from mild to severe. If you suspect that the disease is urgently needed to see a doctor.

Aplasticheskaya anemia, believed, caused by, that the patient's own immune system attacks the bone marrow, preventing the production of blood cells. In some cases, Aplastic anemia is a temporary side effect of medication and can pass on their own after the termination of their admission.

Risk factors

Factors, which increases the risk of aplastic anemia:

• Exposure to certain environmental toxins, contained in gasoline, paint, oil, solvents, Industrial Emissions;
• High-dose chemotherapy and radiation exposure;
• Some viruses;
• Some medications (eg, antibiotics, some drugs, medications, used to treat rheumatoid arthritis);

• Pregnancy;
• Unknown causes.

• Fatigue;
• Dyspnea on exertion;
• Weakness;
• Cardiopalmus;
• Pale skin;

• Skin rash;
• Fever;
• Reduced attention span.

Diagnosing Anemia aplasticheskoй

Tests to diagnose aplastic anemia include:

• Анализ крови – образец крови берется для определения отклонений от нормы количества клеток крови (erythrocyte, leukocytes or platelets);
• Биопсия костного мозга – процедура позволяет врачу взять небольшие образцы костного мозга. The sample is examined under a microscope, to exclude other diseases of the blood and for determining the quantity and quality of bone marrow cells. When aplastic anemia bone marrow will contain fewer blood cells, than usual.

Once a diagnosis of aplastic anemia is confirmed, You may need additional tests, to determine the underlying cause.

Для дальнейшего обследования и лечения пациента могут направить к специалисту по заболеванием крови – гематологу, or in a special center for the treatment of aplastic anemia.

Treatment for aplastic anemia

The type of treatment depends on the severity of the disease and causes.

Blood transfusion

Blood transfusion provides the body with the blood cells, which the bone marrow stops producing. This is not a complete treatment, but it helps to relieve the symptoms of anemia.

Admission immunodepressants

These drugs alter or suppress the immune system, to prevent damage to the bone marrow cells. It gives bone marrow time, to recover and begin producing blood cells again. Preparations, применяемые для этих целей – антитимоцитарный глобулин (ACA) and cyclosporine. They are sometimes used in combination with steroids, to reduce the side effects. This method of treatment often requires brief hospitalization.

Bone marrow transplantation

Replacing the bone marrow of the patient healthy is the best treatment option for some patients with severe aplastic anemia. For successful transplantation, requires the donor bone marrow, that matches the patient's bone marrow so close, as much as possible.

Other treatments

If aplastic anemia, mild or moderate, and it is caused by exposure to radiation, chemicals or drugs, address the identified causes can be quite, to restore normal bone marrow function.

Prevention of aplastic anemia

Although in most cases the appearance of aplastic anemia cannot be avoided, limiting the impact of certain environmental toxins Wednesday, contained in gasoline, paint, oil and industrial emissions, You can reduce the risk of developing the disease.
