title: [Antineutrophil cytoplasmic antibodies (ANCA): study of their presence in diseases not associated with arteritis].
abstract: Our study describes the presence of antineutrophil cytoplasmic antibodies (ANCA) in a group of different pathologies comprising 101 patients. Rheumatoid arthritis, systemic lupus erithematosus, idiopatic neutropenia, acute post-streptoccocal glomerulonephritis, minimal change nephrotic syndrome, Downs syndrome, adult periodontitis, tumoral calcinosis, monoartheritis and lipodystrophy were investigated for ANCA, through indirect immunofluorescence and an indirect solid-phase immunoassay (ELISA). Our results show the pattern of distribution of ANCA in the diseases investigated, and allowed us to make the first description of ANCA in diseases such as Downs syndrome, acute post-streptococcal glomerulonephritis and adult periodontitis. The high percentage of reactivity for ANCA detected in adult periodontitis, raise important questions about the possibility of reporting inaccurate percentages of positivity for some diseases, due to the presence of a concurrent disease such as adult periodontitis.
