Behcet's Disease, Churg-Strauss Syndrome, Giant Cell Arteritis, Microscopic Polyangiitis, Polyarteritis Nodosa, Takayasu's Arteritis, Wegener Granulomatosis
Conditions
Brief summary
The purpose of this study is to provide validation of patient-reported data in the VCRC Patient Contact Registry by comparing patient-reported data with data provided by the physician who is the primary provider caring for the patient's vasculitis. Patients enrolled in the Patient Contact Registry with Behcet's disease, eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA), giant cell arteritis (GCA), granulomatosis with polyangiitis (Wegener's) (GPA), microscopic polyangiitis (MPA), polyarteritis nodosa (PAN), and Takayasu's arteritis (TAK) were invited via email to participate in this study.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Validation of the currently utilized VCRC Patient Contact Registry Questionnaire | Up to 24 months from the date of the last patient assessment | The outcome measure(s) will be evaluated based on the cross-sectional online questionnaire. The questionnaire is the only study procedure for this online patient contact registry protocol and will be the sole analysis tool for both the primary and secondary outcome measures. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate diagnostic accuracy of specific questions | Up to 24 months form the last patient assessment received | The outcome measure(s) will be evaluated based on the cross-sectional online questionnaire.
