Quality of Life and Disease-related Symptoms in Individuals With Systemic Mastocytosis

Quality of Life and Disease-related Symptoms in Individuals With Systemic Mastocytosis

Systemic Mastocytosis is a rare and complex disease caused by accumulation of mast cells. The skin, bones, gastrointestinal tract, bone marrow and liver are the organs most often affected. Symptoms can vary greatly between patients. The study aims to describe the Swedish cohort's self-rated quality of life and levels of disease-related symptoms.

Systemic Mastocytosis (SM) is a rare and complex disease caused by accumulation of mast cells leading to release of mediator substances (e.g., cytokines, prostaglandins, histamine and tryptase). The skin, bones, gastrointestinal tract, bone marrow and liver are the organs most often affected. Symptoms vary between patients and can include e.g., allergic reactions with anaphylaxis, rashes, osteoporoses, cognitive difficulties, fatigue, depression, anxiety, nausea, vomiting, stomach pains and diarrhea. In this cross-sectional observational study, the aim is to include the Swedish cohort of persons diagnosed with SM to gather a wide range of information on self-rated health-related quality of life, gastrointestinal symptoms, pain, anxiety, depression and self-care.

Inclusion Criteria:

• Swedish-speaking individuals aged 18 years or older and diagnosed with indolent systemic mastocytosis (ISM) or advanced systemic mastocytosis (AdvSM), verified by a bone marrow biopsy

Exclusion Criteria:

• An assessment by the treating physician that the individual has a cognitive impairment making participation impossible
• The patient has undergone an allogeneic stem cell transplant
