Myelofibrosis – Causes, Symptoms, and Management

People with myelofibrosis have development issues in their bone marrow cells. Myelofibrosis is a kind of bone marrow cancer that severely and adversely affects the body’s blood cell production. Individuals with myelofibrosis may either develop the condition primarily or have it because of other bone marrow or blood cell-related disorders. There is no permanent cure for myelofibrosis, but specific treatment alternatives can help keep the condition at bay. Here are some details about myelofibrosis:
Myelofibrosis symptoms
Oncologists and other kinds of healthcare experts can diagnose myelofibrosis when they detect some of the following signs and symptoms in individuals:
Fatigue and shortness of breath
Myelofibrosis is a condition that gradually worsens. Hence, detecting it is not easy in its initial stages. One of the most common symptoms of this condition is anemia, a disorder in which oxygen is reduced drastically in a person’s blood. Therefore, in myelofibrosis, an individual does not have sufficient red blood cells to carry enough oxygen to their cells and tissues. This results in such people frequently being tired and out of breath, even after performing the simplest tasks like climbing stairs or skipping a few times.
Frequent bruising and bleeding
Myelofibrosis-caused anemia also results in a person not having enough platelets in their body. Platelets are critical components in an individual’s blood as they facilitate blood clotting. Low platelet count results in people suffering frequent cuts and wounds and unstoppable bleeding.
Abdominal pain
A person having myelofibrosis starts showing several digestive problems due to the gradual enlargement of the veins in their esophagus and stomach. This enlargement causes frequent vessel ruptures and internal bleeding in people with this condition. Also, myelofibrosis causes the enlargement of a person’s liver and spleen, causing sharp abdominal pain. Other abdominal issues include appetite loss, feeling full without eating much food, and rib pain.
Night sweats and fever
People with myelofibrosis include Myeloproliferative neoplasms (MPN) in patients. MPNs produce large amounts of cytokines, an enzyme that increases the frequency of inflammation in patients. This results in excessive sweating for people living with myelofibrosis. Similarly, frequent episodes of fever are also common in this condition.
Itchy skin
MPN-based cytokines also facilitate the release of histamines in people living with myelofibrosis. Histamines are the primary trigger of skin itching in patients. Skin itching then creates rashes and bruises on the epidermis of people with myelofibrosis. The result of the itching and rashes is bleeding that does not clot soon.
Bone and joint pain
Myelofibrosis causes a person’s bone marrow to become more complex and fragile. These symptoms affect the joints and connective tissue surrounding a person’s bones. Marrow hardening also causes inflammation in these parts, resulting in bone and joint pain in people suffering from myelofibrosis.
Myelofibrosis causes
There are several ways in which a person can start developing myelofibrosis symptoms. As stated above, one of the leading causes is other bone marrow or blood cell-related conditions. The leading cause of this condition is genetic mutations.
The stem cells in a person’s body make up their blood components, such as white blood cells, platelets, and red blood cells. Genetic mutations in their DNA can result in eventual myelofibrosis. In addition, the bone marrow stem cells in such a person’s body develop abnormally over time.
Now, what exactly triggers such a mutation is not precise and is the subject of extensive medical research. One of the several reasons for the mutation is erratic Janus-associated kinases (JAKs) behavior. JAKs facilitate blood cell production in a person’s bone marrow by regulating cell growth and division. If JAKs behave abnormally, the body produces too many or too few blood cells. This results in myelofibrosis.
Research studies have found that approximately 90 percent of individuals with myelofibrosis suffer a mutation in one of three genes, namely, JAK2, CALR (a gene that makes a protein to regulate the amount of calcium stored in cells), or MPL (a gene which produces a protein to control the number of blood cells made in a person’s bone marrow).
Currently, there is no way to prevent myelofibrosis, but healthcare researchers are trying to find avenues for the same.
Certain people are more vulnerable to this condition compared to others. For example, people over 50 are more likely to develop myelofibrosis compared to younger individuals. Additionally, people frequently exposed to chemicals like benzene and toluene tend to suffer from myelofibrosis eventually.
Apart from these, individuals whose occupation involves frequent radiation exposure often go on to develop myelofibrosis. And lastly, a small percentage of people with other blood cell diseases such as polycythemia vera or essential thrombocythemia, tend to suffer from myelofibrosis eventually.
Myelofibrosis remedies
Some of the ways in which severe myelofibrosis can be treated are:
Hormone therapy
This treatment alternative involves the usage of androgen, a distinctly male hormone, to boost red cell production in a person’s body. Like the other treatment alternative, the effectiveness of hormone therapy is moderate.
Blood transfusion
Frequent and regular blood transfusions can drastically increase a person’s body’s red blood cell count. While this treatment alternative can address anemia and its symptoms, such as weakness, blood clotting issues, and fatigue, carrying it out can be tiresome for people with myelofibrosis and their loved ones.
Stem cell transplantation
Allogenic stem cell treatment is arguably the only potential cure for this condition. This treatment involves healthcare experts transplanting healthy stem cells into the body of persons with myelofibrosis. This treatment is a high-risk alternative and may prove fatal if things go wrong during the procedure. However, due to its risky nature, older people with myelofibrosis are not advised to undergo stem cell transplantation.
Radiation therapy
This option involves using powerful radiation beams to kill cancerous cells and inhibit the enlargement of a person’s spleen.
