Effects of stress on inflammatory autoimmune disease: destructive or protective?

Abstract

We have summarised evidence in the literature for modulatory effects of stress on inflammatory autoimmune disease. We find that overall there is strong evidence for such an interrelationship. Apparent discrepancies between groups and studies are probably due to differences in experimental design, whether longitudinal or retrospective. Other important variables are the specific effects of different types of stress and the intensity and timing of the stressor relative to onset of inflammation. We conclude that there is much of benefit to be learned from scientific study of stress, such as harnessing and rationalising of stressful experiences through self-expression in patients, or the identification of novel anti-inflammatory compounds activated by stress.
