About
This study will examine the genetic and immune factors involved in the cause and development of psoriatic arthritis-a disease of both the skin and joints. It will describe the medical features and natural course of the disease and determine participants' eligibility for experimental treatment protocols.
Patients 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:
Patients will be followed once or twice a year and may be evaluated for participation in an experimental treatment study.
Participating 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).
Full description
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.
