Linking environmental agents and autoimmune disease: an agenda for future research.

Autoimmune diseases are influenced by multiple factors including genetics, age, gender, reproductive status, hormones, and potential environmental contaminants. A workshop, "Linking Environmental Agents and Autoimmune Diseases," was convened at the National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina, 1-3 September 1998, to review current knowledge about links between environmental exposures and autoimmune disease, to identify and prioritize research needs, and to develop an integrated, multidisciplinary research agenda. Participants spent the last half-day of the workshop in small group discussions for the purpose of developing consensus on research needs. Research needs identified were a) develop research tools needed to explore links between environmental agents and autoimmune disease; b) establish a disease registry or surveillance system; c) develop and validate strategies for screening chemicals for the potential to induce or exacerbate autoimmune disease; d) develop an emergency response strategy to gain information from accidental exposures; and e) conduct hypothesis-driven research in occupationally exposed groups and/or in experimental animals. There was consensus that meetings like this workshop and projects that facilitate interactions between specialties should be encouraged. A multidisciplinary approach is needed to address this problem.
