title: [Diagnostic and prognostic significance of so-called rheumatoid vasculitis].
abstract: 23 patients with rheumatoid arthritis and high rheumatic factors (mean titres of rheumatic factors 1 : 1 434) within a prospective study on the diagnostic and prognostic significance of the rheumatoid vasculitis which was performed together with the Research Institute for Rheumatism Moscow underwent examinations for the proof of an extraarticular organ manifestation. In correspondence with the data in literature we found rheumatic nodes (70%) as most frequent extraarticular organ manifestation. In 1 patient each a participation of the lungs and a rheumatic exudate of the pleura, respectively, could be diagnosed. In another patient there were references to a vasculitis at the fundus of the eye. In only 2 patients there was a vasculitis of the digital arteries with necroses, in one of them a generalized vasculitis. 5 of the 13 neurologically examined patients showed polyneuropathic symptoms. Of the biochemical findings the C-reactive protein and the blood sedimentation rate showed clear increases and correlations.
