Description of intervention(s) / exposure
Adults who had a renal biopsy confirmed ANCA vasculitis will be invited to participate.
Participants will have their data collected via questionaires, data collection from patient contact will include their past occupational history, environmental exposure to hazards including silica, dust, fumes, pesticides... There are no intervention planned in this study. Participants are required to complete questionnaires at enrolment only.
Other data collected are from patient's medical records, including historic blood serological results, basic demographics, past treatment received and clinical response. Data will be collected via accessing in hopsital paper medical charts, Integrated Electronic Medical Records (ieMR) and Pathology Queensland database (AusLab/AusCare). These data are collected retrospectively covering study period of 2005-2021 and does not require any patient contact.
