NCT05416723

Brief Summary

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. The secondary objectives are as follows:

  • Description of cases of ANCA vasculitis seen in French occupational pathology consultation centres:
  • reasons for consultation,
  • occupational and environmental etiologies described
  • occupational situations responsible
  • aptitude notices
  • 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.
