It will describe the medical features and natural course of the disease and determine participants' eligibility for experimental treatment protocols.\n\nPatients with known or suspected psoriatic arthritis 5 years of age and older and their relatives may enroll in this study. Patients will be evaluated with a medical history and physical examination, electrocardiogram, blood tests and X-rays. Additional procedures may include:\n\n1. Leukapheresis-Collection of white blood cells for genetic analysis. Whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The plasma is removed and the cells are returned to the body through a second needle placed in the other arm.\n2. Skin biopsy-Removal of a small skin sample for microscopic analysis. An area of skin is numbed with an anesthetic and one to three small circular portions (about 1/4 inch in diameter) are cut and removed.\n3. Joint aspiration-Removal of a small sample of synovial fluid (lubricating joint fluid). An area of skin around the biopsy site is numbed with an anesthetic, and a needle is inserted into the joint to pull out a small fluid sample.\n4. Synovial needle biopsy-Removal of a small sample of synovial tissue (tissue lining the joint). An area of skin around the biopsy site is numbed with an anesthetic and a large needle is inserted into the joint. A smaller needle attached to a syringe is then placed inside the larger needle and small pieces of synovial tissue are removed.\n5. Genetic studies-Saliva and blood samples will be collected for gene testing. Saliva is collected by rinsing the mouth with a tablespoon of salt water and spitting into a test tube.\n\nPatients will be followed once or twice a year and may be evaluated for participation in an experimental treatment study.\n\nParticipating relatives of patients will fill out a brief medical history questionnaire and provide a DNA sample (blood sample or tissue swab from the inside of the cheek).", "detailedDescription"=>"Patients with known or suspected psoriatic arthritis will be evaluated at the Clinical Center. Studies will include characterization of the clinical and laboratory features of the disease, research studies of the natural history and pathogenesis, genetic studies, and determination of the patient's eligibility to enter experimental therapeutic protocols. Patients may be asked to contribute blood, skin or synovial membrane samples for immunologic and genetic research studies."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD", "ADULT", "OLDER_ADULT"], "healthyVolunteers"=>false, "eligibilityCriteria"=>"INCLUSION CRITERIA:\n\nPsoriatic arthritis (proven or suspected) or;\n\nFamily history of psoriasis or psoriatic arthritis (i.e. family members of patients with psoriasis or psoriatic arthritis); and\n\nWillingness and ability of the subject or guardian to give informed consent.\n\nEXCLUSION CRITERIA:\n\nConcomitant medical problems which would confound the interpretation of immunological studies.\n\nConcomitant medical, surgical or other conditions for which inadequate facilities or funds are available to support their care at the NIH."}, "identificationModule"=>{"nctId"=>"NCT00001420", "briefTitle"=>"Study of Psoriatic Arthritis", "organization"=>{"class"=>"NIH", "fullName"=>"National Institutes of Health Clinical Center (CC)"}, "officialTitle"=>"Studies of the Pathogenesis and Natural History of Psoriatic Arthritis", "orgStudyIdInfo"=>{"id"=>"950082"}, "secondaryIdInfos"=>[{"id"=>"95-AR-0082"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"20892", "city"=>"Bethesda", "state"=>"Maryland", "country"=>"United States", "facility"=>"National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)", "geoPoint"=>{"lat"=>38.98067, "lon"=>-77.10026}}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)", "class"=>"NIH"}}}}
