The term “myelodysplastic syndrome” MDS refers to a set of diseases in which aberrant blood-forming cells originate in the bone marrow. These cells first obstruct the creation of regular blood cells. These cells may later become malignant, resulting in a type of leukemia.
Symptoms vary depending on which cells are damaged, but they can include fatigue, weakness, and paleness, as well as fever and infections, as well as bleeding and bruising.
For diagnosis, blood tests and an evaluation of a bone marrow sample are required.
Azacytidine with decitabine treatment may help ease symptoms and reduce the risk of acute leukemia developing.
The disorder can be cured by stem cell transplantation.
A line of identical cells (clones) forms and occupies the bone marrow in myelodysplastic disorders. These aberrant cells don’t mature or expand normally. The cells also disrupt normal bone marrow function, leading to deficiencies in immune function.
- Anemia is caused by a lack of red blood cells.
- Infection-causing white blood cells
- Platelets are responsible for bruising and bleeding.
The formation of red blood cells is primarily influenced by some people. Myelodysplastic syndromes are more common in adults over the age of 50, especially those over the age of 65. Men are more likely to be affected than women. In most cases, the cause is unknown. However, bone marrow exposure to radiation therapy or some types of chemotherapy medications may play a role in some patients.
Myelodysplastic Syndrome Symptoms
Symptoms may appear gradually. Anemia causes fatigue, weakness, and other symptoms. If the quantity of white blood cells falls, fever due to infection may occur. If the quantity of platelets reduces, it can lead to easy bruising and irregular bleeding.
Myelodysplastic Syndrome Diagnosis
Blood tests
Bone marrow examination
Molecular testing
When persons have unexplained persistent anemia, a myelodysplastic syndrome may be suggested, but diagnosis requires a bone marrow examination.
People are tested at some clinics to see whether the gene or chromosome abnormalities are causing their myelodysplastic syndrome sometimes called molecular testing. Some of these specific defects are currently being targeted by experimental medicines.
Myelodysplastic Syndrome Prognosis
Myelodysplastic syndromes are considered to be a kind of preleukemia that occurs slowly over several months to years. A myelodysplastic condition can lead to acute myeloid leukemia in 10 to 30% of persons (AML).
Myelodysplastic Syndrome Treatment
Chemotherapy
In some cases, stem cell transplantation is necessary.
The medications azacitidine and decitabine help to ease symptoms and reduce the risk of developing acute leukemia. Azacitidine may also help you live longer. The only curative treatment is stem cell transplantation, which is mainly performed on young people.
If transformation to AML occurs, chemotherapy, such as that used to treat AML, may be beneficial, but chemotherapy alone is unlikely to cure this type of AML.
Treatment of myelodysplastic syndrome complications
Transfusions of red blood cells are frequently required by people with myelodysplastic syndromes. Blood transfusions are reduced thanks to a medicine called lenalidomide, which targets cells with a specific genetic defect. Platelets are only transfused if a person’s bleeding is uncontrollable or if surgery is required and the platelet count is insufficient.
People with low numbers of neutrophils, the white blood cells that fight infection, may benefit from injections of granulocyte colony-stimulating factor on a regular basis. The proteins erythropoietin, which aids in the creation of red blood cells, and thrombopoietin, which increases platelet development, may also be beneficial.
Summary
The spongy tissue inside certain of your bones, such as your hip and thigh bones, is called bone marrow. It contains stem cells, which are immature cells. The stem cells can differentiate into red blood cells, which transport oxygen throughout the body, white blood cells, which fight infections, and platelets, which aid in blood clotting. The stem cells in myelodysplastic syndrome do not develop into healthy blood cells. The bone marrow is where many of them die. This indicates a lack of healthy cells, which might result in infection, anemia, or easy bleeding.
