Full Answer
How is systemic mastocytosis diagnosed and treated?
Diagnosis of systemic mastocytosis should be established by a bone marrow biopsy, which would reveal an abnormally high number of mast cells with abnormal appearance. Currently, there is no curative treatment for mastocytosis. Treatment of mastocytosis is primarily directed at controlling the symptoms caused by the release of mast cell mediators.
What is the mastocytosis Society?
The Mastocytosis Society. is a non-profit organization dedicated to supporting patients affected by Mastocytosis and Mast Cell Activation Diseases as well as their families, caregivers and physicians through research, education and advocacy.
What is the treatment for mastocytosis with beta tryptase?
Beta tryptase is stored in mast cell granules and is detectable in circulation after anaphylaxis usually returns to baseline after 4 hours. Currently, there is no curative treatment for mastocytosis. Treatment of mastocytosis is primarily directed at controlling the symptoms caused by the release of mast cell mediators.
What are the treatment options for mast cell activation?
Mast-cell stabilizers such as ketotifen can be used to treat some mast cell activation symptoms. Leukotriene antagonists can also be used to improve symptoms in patients. Proton-pump inhibitors can be used to treat the increased acid production in the stomach.
How can I help someone with mastocytosis?
Steroid cream. Mild to moderate cases of cutaneous mastocytosis can be treated with a very strong steroid cream (topical corticosteroids) for a limited length of time, usually up to 6 weeks. Steroid cream reduces the number of mast cells that can release histamine and trigger inflammation inside the skin.

Is systemic mastocytosis curable?
There is no cure for mastocytosis, although several treatments can be used to relieve symptoms and remove a mastocytoma (see the Introduction section). Descriptions of the most common treatment options for mastocytosis are listed below.
How many people have aggressive systemic mastocytosis?
Systemic mastocytosis is estimated to occur in 1 per 10,000 to 20,000 individuals worldwide.
What is the condition of mastocytosis?
Mastocytosis is a rare disorder characterized by abnormal accumulation and activation of mast cells in the skin, bone marrow and internal organs (liver, spleen, gastrointestinal tract and lymph nodes). Mastocytosis can affect both children and adults. Mastocytosis can be classified to a specific type depending on the patient’s symptoms and overall presentation. Cases beginning during adulthood tend to be chronic and involve the bone marrow in addition to the skin, whereas, during childhood, the condition is often marked by skin manifestations with no internal organ involvement and can often resolve during puberty. In adult patients, mastocytosis tends to be persistent, and may progress into a more advanced category in a minority of patients.
What is the most common disease associated with systemic mastocytosis?
Systemic mastocytosis with an associated hematologic neoplasm affects approximately one-fifth of all patients with systemic mastocytosis. Myeloproliferative and myelodysplastic disorders are the most common diseases associated with this form and patients may lack urticaria pigmentosa-like skin lesions.
What is the high level of tryptase in SSM?
This variant of systemic mastocytosis is characterized by high mast cell burden as evidenced by high level of tryptase (>200 ng/ml) and high degree of bone marrow involvement with mast cells (>30% in biopsy tissue), splenomegaly or hepatomegaly with or without mild abnormalities in production of other blood cells, without an overt hematologic disorder. Patients with SSM may have a higher likelihood of progressing to an advanced disease category below.
How do you know if you have mastocytosis?
In general, symptoms occurring in mastocytosis are mainly due to the release of chemicals from the mast cells and thus produce symptoms associated with an allergic reaction, although a true allergic trigger may not be identified. Flushing and gastric acid hypersecretion due to mast cell-associated histamine release are common symptoms. Heartburn, stomach aches, abdominal discomfort, bloating and diarrhea may occur. The liver, spleen and lymph nodes may become enlarged in advanced disease varieties; therefore regular follow-up is necessary. Bones affected by mastocytosis may become softened (osteoporosis) and deteriorate, although some new bone growth may occur with thickening of the outer portions or spongy inner areas of the bones. In aggressive systemic mastocytosis, a decrease in blood cells (cytopenia), break-down of bones (osteolysis), swelling of the lymph nodes (lymphadenopathy), swelling of the liver (hepatomegaly), impaired liver function, ascites or portal hypertension and malabsorption, may also occur.

Mast cell leukemia. Mast cell leukemia is an aggressive hematological malignancy characterized by presence of circulating mast cells greater than 10%, or immature mast cells in bone marrow aspirates greater than 20%. This subtype is very rare; however, it is associated with the worst prognosis among all mastocytosis varieties. Mast cell sarcoma.
When does mastocytosis start?
Mastocytosis affects males and females in equal numbers. It can begin during childhood or adulthood. Childhood-onset disease most commonly presents within the first year of life.
Patient Education
Systemic mastocytosis is a rare blood disease that is caused by too many mast cells, a type of white blood cell, being produced in the bone marrow. This disease is rarely inherited. It is usually acquired due to genetic mutations. 1
Self-Care Recommendations
While there is currently no cure for systemic mastocytosis, there are certain steps that can be taken to reduce the risk of reactions and manage them effectively when they occur.
Medical Alert Bracelets
Another step that is highly advisable is purchasing a medical alert bracelet to wear at all times. A list of a patient’s medical conditions can be inscribed on the bracelet. This may help others understand the patient’s condition and advise them on needed actions if the patient is unable to speak to them for any reason. 3
Diet
Some foods are naturally high in histamine, while others trigger a release of histamine by activating mast cells. Both may increase the likelihood of an allergic reaction.
Exercise
One potential trigger for allergic reactions in systemic mastocytosis is exercise because it elevates the body’s internal temperature and is considered a form of stress on the body. Extreme temperature changes and stress trigger mast cell activation, so avoiding strenuous exercise, especially on hot, humid days, is advised. 3,12
Clothing and Skin Care
Loose-fitting, comfortable clothing should be worn to avoid friction, scratching, rubbing, or constriction of the skin, which may trigger a response. Wearing clothes made of natural fibers and keeping the skin moisturized may also reduce itching. 3
Stress
Stress management is important to decrease emotional stress and anxiety, which may trigger the immune system. 3,11,12
Diagnostic Process
Knowing where to start the diagnostic process can be hard. For many, it begins at a front-line health care service, such as a primary care doctor's office, urgent care center, or an emergency room. A diagnosis may become clear through these visits or only after specialized testing and referrals.
Building a Medical Team
Building a medical team can help speed diagnosis and improve medical care. The primary care physician (PCP) is usually the center of the team. The involvement of other specialists depends on the type of symptoms or the need for special evaluations or treatments. The need for different specialists may change over time.
Getting a Diagnosis
To begin the diagnostic process, a doctor or other health care provider will take a medical history by asking questions about the patient's current symptoms and diagnoses. They also commonly ask about the past medical history, medications, allergies, the patient's social history, and the family's medical history.
Management and Treatment
Management and treatment of a disease often depends on the specific diagnosis and the type and severity of associated symptoms. A primary care provider (PCP) can help coordinate care when multiple specialists are involved.
