Summary:[...]ANCA help with the diagnostic workup of AAV and should be interpreted together with clinical and histological data. [...]drugs, such as hydralazine, propylthiouracil and levamisole-adulterated cocaine, can induce secondary forms of AAV. 6 Based on associations with genetic background and epidemiology, it has been suggested that ANCA specificity (PR3-ANCA vs MPO-ANCA) could be better than clinicopathological diagnosis (GPA, MPA) for defining homogeneous groups of patients. 7 8 We agree with Novikov et al 1 that this discussion cannot be finalised yet. In some gastrointestinal disorders such as ulcerative colitis, autoimmune hepatitis and primary sclerosing cholangitis, atypical ANCA can be detected by IIF. 9 10 As the target antigen is not known, specific immunoassays are not available. [...]Novikov et al 1 addressed some important points related to correct ANCA use and interpretation. Detection of antineutrophil cytoplasmic antibodies (ANCAs): a multicentre European Vasculitis Study Group (EUVAS) evaluation of the value of indirect...
