Mast cells release chemicals that can cause itching, blisters, flushing, bone pain, and abdominal pain. Little is known about the disease and there is no cure. Steroids and antihistamines can help reduce some symptoms.\n\nPatients from birth to 80 years of age with increased mast cells in at least one organ system may be eligible for this 3-year study. Family members may also be enrolled for genetic testing.\n\nPatients will be evaluated yearly at the NIH Clinical Center with the following tests and procedures:\n\nMedical history and physical examination.\nBlood samples.\nLaboratory blood tests, as medically indicated.\nBone marrow aspiration and biopsy - For the bone marrow aspiration and biopsy, the back hipbone is punctured with a sterile needle. Five milliliters (1 teaspoon) of marrow is withdrawn through a syringe and a 1/2-inch piece of tissue is extracted with a special needle.\n\nThe blood and bone marrow samples will be used for clinical care and for research to determine if mastocytosis is due to mast cell growth factors or genetic changes.\n\nPatients who require further evaluation and tests will have recommendations made to their primary physician. Any patient who requires immediate treatment will be admitted to the hospital. Standard medical treatment may include antihistamines for itching; steroids for severe abdominal symptoms such as cramping, diarrhea, and evidence of increased mast cells determined by an upper GI study; and adrenaline for anaphylactic shock. Patients who do not respond to conventional treatment may be offered participation in an experimental therapy study.\n\nParticipating family members will have a medical history and a blood sample drawn to look for genetic abnormalities.", "DetailedDescription"=>"This protocol is designed to examine those growth potentiating and inhibiting factors which regulate mast cell number in patients with mastocytosis, and to explore the molecular basis of the disease process in hopes of improving therapy. Patients entered into the study are seen initially and may elect to be reevaluated yearly. The majority of patients to be entered into this protocol are currently followed at NIH on other protocols. Medical workup and treatment are in accordance with standard medical practice. The protocol is for 3 years, to be extended as facilities, faculty, and patients permit."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Subjects include children and adults from birth to 80 years of age.\n\nParticipants must have histologic evidence of an increased mast cell number in at least one organ system.\n\nMust be willing to be seen at the NIH according to protocol guidelines.\n\nRoutine medical care must be available through their referral physician.\n\nPatients with mastocytosis now followed at the NIH on protocol 88-I-0190 will be continued on this study."}, "IdentificationModule"=>{"NCTId"=>"NCT00001356", "BriefTitle"=>"Characteristics of Mast Cells in Mastocytosis", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Institutes of Health Clinical Center (CC)"}, "OfficialTitle"=>"Culture and Characteristics of Mastocytosis Mast Cells", "OrgStudyIdInfo"=>{"OrgStudyId"=>"930136"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"93-I-0136"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"20892", "LocationCity"=>"Bethesda", "LocationState"=>"Maryland", "LocationCountry"=>"United States", "LocationFacility"=>"National Institute of Allergy and Infectious Diseases (NIAID)"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Institute of Allergy and Infectious Diseases (NIAID)", "LeadSponsorClass"=>"NIH"}}}}}}
