Standardization of autoimmune diagnostics in Germany: activities of the German group in the European Autoimmune Standardization Initiative.
The German Regional Group of EASI was established during the annual Meeting of the German Society of Immunology in Kiel in September 2005. Since this initial informative meeting, an active core group of about a dozen rheumatologists, immunologists, and laboratory specialists has been generating starter projects. In general, these projects do focus on clinically associated diagnostic questions, and do integrate a variety of specialists with profound knowledge in several related subjects. The aims of the German EASI group are to contribute to the definition of standards and to improve patient care. Therefore, the group is establishing guidelines for the diagnosis of autoimmune diseases, to standardize and improve their quality, combining the experience of clinical and laboratory specialists. The diagnostic activities focus currently on systemic lupus erythematosus (SLE) and on rheumatoid arthritis. These activities include laboratory investigations and diagnosis through clinical manifestations. Standardized diagnostics cannot be based solely on vague symptoms and positive laboratory tests. In laboratory diagnostics, standardization and implementation of objective methods for the detection of autoantibodies has been identified as a central challenge. Here, immune fluorescence techniques and the evaluation of RibP are used as first parameters that could improve SLE diagnostics. Furthermore, guidelines and proposals from scientific medical organizations, and in particular from other national EASI groups will be adapted to the German health system. A cornerstone of implementation is the identification and logistic preparation of existing serum banks, the definition of gaps that should be bridged, and, particularly, the definition and collection of adequate control groups. Through these measures, the German EASI group will provide a standardized diagnostic model of autoimmune disorders throughout Europe starting in the field of rheumatology. Diagnostics may become more rational, efficient, faster, and cost-efficient. Patients with autoimmune rheumatic disorders will profit from receiving an earlier and more accurate diagnosis, which again will allow earlier therapeutic intervention and lead to a better long-term clinical outcome.
