5 Facts you should know

The most frequent symptoms associated with the disease include pruritis, flushing, itching, diarrhea, and anaphylaxis
FACT
The spectrum ranges from indolent SM, which is predominantly characterized by severe constitutional symptoms caused by mast cell degranulation and mediator release, to advanced SM, which is characterized by organ dysfunction and reduced survival due to mast cell infiltration
FACT
Across all forms of SM, the KIT D816V mutation is the primary driver of disease
FACT
The vast majority of patients have non-advanced (indolent or smoldering) SM, with debilitating symptoms that lead to a profound, negative impact on quality of life

Current treatments
The treatment for mastocytosis depends on the particular symptoms of each person. Treatment for symptoms that affect the skin include antihistamines and oral psoralen plus UVA (PUVA) therapy. If the symptoms are not responsive to other treatments, a doctor may prescribe steroid creams, ointments, or solutions applied to the skin (topical corticosteroids treatment). Proton pump inhibitors can be used to treat gastrointestinal symptoms and bone pain. Different treatments work better for some people than others.
