Thrombocythemia

Thrombocythemia






The condition in which excess of blood platelets called thrombocytes are produced, is called thrombocythemia. Three types of blood cells are available namely red blood cells, white blood cells and platelets. These platelets are called thrombocytes and are responsible for clotting of blood during accident or injury. When the number of platelets is high blood begins to clot easily which can obstruct the blood vessels sometimes causing Stroke or myocardial infarction. Essential thrombocythemia is common in old age and is more prevalent in women than men.


Symptoms :










Some people may not have any symptoms during thrombocythemia and they need not have to take any treatment. Some of the symptoms of this disorder is formation of Blood Clots in hands, feet and extremities of the body. Other common signs are Headache, fatigue, chest pain, drowsiness, vision problems, confusion or fainting, tingling sensation in hands and feet, burning pain in the regions of blood clot and enlarged Spleen or liver.


Bleeding can occur in nose or mouth and sometimes even on the stool. In severe cases of blood clot it can cause transient ischemic attack causing stroke. In that case, there can be symptoms like numbness on face, arms, legs, double vision or partial loss of vision and difficultly in speech.


Causes :


The major cause for thrombocythemia is over production of thrombocytes. Bone marrow produces all the three types of blood cells which then travel through the blood vessels. Normal range of platelet count is 150,000-450,000 in one microliter of blood. But a person having this disorder will have too much of platelets in the blood which would eventually lead to abnormal bleeding or clotting.


It is believed to be caused by gene mutation. Nearly half the people with this problem will have Janus Kinase 2 gene which is defective.


Complications :


Thrombocythemia can cause Miscarriage or premature delivery in pregnant women or any other complications affecting the growth of the fetus. Very often, increased count of thrombocytes may cause Heart Attack or stroke and sometimes acute bone marrow cancer and myelo-fibrosis.


Diagnoses :


Your doctor may do complete blood count test for verifying the platelets or a blood smear test. Sometimes bone marrow biopsy or aspiration test is done for detecting cancer or for finding out the root cause of high platelets.


Treatment :


Actual cause of the problem should be identified before treatment begins. The nature of treatment depends on the rate of blood clotting episode or bleeding. Medicines are given to reduce the platelets and to prevent the affected person from cardiovascular problems.


Your doctor will put you on low dosage of aspirin which is capable of making the platelets less sticky thus preventing it from clotting. Medications like Droxia, hydrea is given for suppressing the release of blood cells. Sometimes this drug is given along with aspirin. But your doctor will have to check the blood count regularly when taking this medicine. Some doctors prescribe Anagrelide or Interferon alfa 2B to control production of excess of platelets. However these drugs can cause some adverse effects which you can discuss with your doctor.


In case of emergency blood clotting, plateletpheresis is done for reducing the platelet count, wherein blood is extracted from the vein by intravenous needle. This tubing is connected to a device for removing platelets alone. The purified blood is then returned to the donor through another IV line.


Home Remedies :


You need to follow healthy diet avoiding trans-fats to reduce your weight. In case you are obese, you should start doing workouts and eat balanced diet for reducing the risk of blood clotting. It is not enough if you increase the duration of physical activity but you have to monitor what you eat daily to attain normal weight. Stop smoking which causes harmful effect on your immune system. While handling knives or razors be careful not to make any cuts.











Thrombocythemia – Symptoms, Causes, Treatment, Medication

Thrombocythemia – Symptoms, Causes, Treatment, Medication

Thrombocythemia Symptoms


Most individuals with this condition will have no symptoms or signs. Usually the first sign that an individual has the disorder can be when there is the progression of Blood Clots. These clots can develop in any area in the body but they occur most frequently in the brain, feet and hands.


Symptoms and signs of this disorder include:



  • Bleeding from the gums

  • Bleeding from gastrointestinal tract

  • Bloody stools

  • Easy bruising

  • Dizziness

  • Rarely enlarged lymph nodes

  • Nosebleeds

  • Headache

  • Numbness of feet or hands

  • Prolonged bleeding after surgical procedures or extraction of teeth

  • Ulcers on toes or fingers


Symptoms which are less common with this disorder can create bleeding, particularly if the count of platelets is very high –greater than 1 million platelets/microliter of blood. Bleeding can consist of:



  • Bleeding from gums or mouth

  • Nose-bleeds

  • Bruising

  • Bloody stool


Any blood clot can cause TIA or “transient ischemic attack” – which is the momentary disruption of blood flowing to a part of the brain – or Stroke. Symptoms and signs normally develop abruptly and consist of:



  • Numbness or weakness of arm, leg or face, customarily on only one side of the body

  • Difficulty with speech or speech understanding – Aphasia

  • Decreased, blurred or double vision


An individual should be checked by a health care professional if:



  • There are unexplained or prolonged episodes of bleeding

  • Chest pains, confusion, leg pain, weakness, numbness or any other new symptoms develop


Thrombocythemia Causes


Bone marrow which is tissue that is spongy located inside the bones encloses stem cells that develop into red cells, platelets, or white cells. Platelets flow thru the blood system. They stick to each other to develop clots anywhere they are needed in order to halt bleeding when there is a damaged blood vessel, for example when an individual sustains a cut. The standard platelet count varies from approximately 150,000 to near 450,000 platelets/microliter of blood.


But with thrombocythemia, the marrow of the bone makes too numerous platelets in the blood. These excess platelets often cannot function ordinarily, leading instead to bleeding or clotting which is abnormal.


The exact reason of this abnormality is not known. Approximately half of individuals with this ailment have a JAK2 gene mutation. Other mutations of genes can be linked with this disorder. The reason that these mutations play a role in causing this disorder is being researched and investigated.
A type of thrombocythemia which is very rare is also genetic.

A platelet count which is very high that is caused by a primary disorder for instance an infection or deficiency of iron is referred to as secondary or reactive thrombocytosis.


The abnormal clotting of the blood in this condition often leads to a diversity of serious complications together with:


Pregnancy Complications
When this disorder is not controlled it can cause high Blood Pressure or Eclampsia">Preeclampsia, early delivery, early parting of the placenta from the uterine wall or Placental Abruption as well as slow growth of the fetus. It also can cause Miscarriages. The pregnant woman should be carefully monitored thru out the pregnancy.


Stroke
Any clot that blocks blood flowing to the brain can create a stroke. If in individual notices any symptoms or signs of a stroke, get medical attention immediately.


Heart Attack
Any clot that blocks blood flowing to the heart can cause a heart attack. If signs of a heart attack occur such as fullness, pressure or squeezing type pain in the middle of the chest which last longer than a couple of moments, pain spreading to the shoulder, back, arm, jaw or teeth, shortness of breath and sweating, get medical attention immediately.


Thrombocythemia Treatment


The treatment of thrombocythemia depends on the risk of episodes of bleeding or blood-clotting. If the individual is younger than 60, with no symptoms or signs and have no further risk factors for developing clots such as smoking, periodic checkups is all that is needed. If the individual is older than 60 and has had any previous signs or symptoms of blood clots, the physician will more than likely prescribe medication or a medical procedure to lower the level of platelets. It also may be recommended treatment if the individual has any risk factors for cardiovascular problems for instance high blood pressure, high cholesterol or diabetes.


Thrombocythemia Medication


If the individual is at risk of blood clots, the physician may recommend low-dose aspirin, especially if that patient is pregnant. Aspirin causes the platelets to be less sticky and therefore less likely to form clots.


Drugs that can reduce the platelet count and commonly used to treat thrombocythemia include:


Hydroxyurea
This drug suppresses bone marrow creation of blood cells including platelets. It is used to treat cancers and it is the most commonly prescribed platelet lowering medication. Long term use has a risk of developing Leukemia


Anagrelide
There is no risk associated with this medication of developing leukemia. But it is not as effective as hydroxyurea. Side effects consist of heart problems, dizziness, nausea and Diarrhea as well as fluid retention.


Interferon alfa-2B
This is given by injection and is less convenient to use as the above 2 medications. It is very expensive and has less tolerable side effects. They are flu-like symptoms, confusion, Depression, nausea, diarrhea, irritability, seizures as well as sleepiness


Plateletpheresis


This is used only in emergencies for instance stroke or other blood clotting problems. This process is used to lower platelet count rapidly. With this procedure, an IV needle is connected to a tube inserted into one of the patient’s blood vessels. Blood flows thru the tube and into a device that removes platelets from the blood. Remaining portion of the blood and red cells are then return to the patient thru an IV line. Effects are only temporary.
