The main objective is to identify specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified by questioning, geographical distribution of cases) from the RNV3P data.

  • recognition as an occupational disease

• Identification of specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified on questioning, geographical distribution of cases).

• For occupational and non-occupational cases of ANCA vasculitis: identification of difficulties encountered by patients at work and proposed work adaptations.

• Estimation of the number of applications for recognition of disabled worker status made within this patient group.

• Identification of clinical severity and autoimmune profiles of ANCA vasculitis of occupational and/or environmental origin.
