recombinant technology, to construct molecules harboring only this relevant epitope region and thus construct better assays in the future.

Are antineutrophil cytoplasmic antibodies a marker predictive of relapse in Wegener's granulomatosis? M., Knoop,., Vikse,. In the present study the capture assay was better than the standard elisa method for discrimination between a relapse and a remission. Footnotes Received 2 December 2002. Association between active Wegener's granulomatosis and anticytoplasmic antibodies.
Many of the studies were performed before IIF for ancas was standardized. This cohort has been monitored prospectively since the day of biopsy, and remissions and relapses have been recorded as published previously ( 19 ). "Thirty-Five Years of Hemodialysis: Two Case Reports as a Tribute to Nils Alwall". Discrepancies are also due to differences in the way in which the antigens are presented in different assays. Thus, minor fluctuations in disease activity during an exacerbation (which may render a change in the Birmingham vasculitis activity score) were not listed as separate relapses.

Most ancas are directed to conformational epitopes on PR3. For 13 of the relapse episodes, the value for the relapse sample could be compared with the values for samples drawn during a disease-free interval prior to the relapse. Anca titres, even of IgG subclasses, and soluble CD14 fail to predict relapses in patients with anca-associated vasculitis. The relationship between the capture elisa results and the IIF results is shown in Fig. The median age of the patients at the time of the first relapse was 50 years (age range, 40 to 82 years). Measurement of antineutrophil cytoplasmic antibodies (ancas) is an established tool for the diagnostic workup of patients with small vessel vasculitis.
