Via email, consent was obtained from at least 20 randomly selected patients with the seven forms of vasculitis detailed above in the VCRC Patient Contact Registry who have completed the Diagnostic Questionnaire. The form was sent in PDF format to the patient, who either printed out or emailed the form to his or her primary vasculitis provider to complete. This form included the same questions in the patient questionnaire, with minor reformatting and a few expanded details to verify the patient-provided data (please see appendix B). If the 20 questionnaires are not returned one month after the initial recruitment email to the Patient Contact Registry participants, 20 additional participants with the seven forms of vasculitis will be selected randomly and will be asked to participate in this study. The survey data is stored by the Rare Diseases Clinical Research Network's (RDCRN) Data Management and Coordinating Center (DMCC) at the University of South Florida. The data is de-identified. Names or other personal health information were not collected. Upon conclusion of the study period, the data will be sent to Dr. Kathleen McKinnon. All data collected will be sent to the database of Genotypes and Phenotypes (dbGaP) to be stored indefinitely.
