Among other mechanisms the loss of sympathetic nerve fibers in inflamed tissue and inadequate cortisol secretion in relation to inflammation lead to an enhanced proinflammatory load in RA. Stress and the subsequent stimulation of inflammation systemic and local lead to increased sensitization of pain and further defects of stress response systems vicious cycle of stress pain and inflammation . In 1937 Hans Selye called the activation of stress systems an alarm reaction which is the reaction of an organism when first confronted with a stimulus to which it is quantitatively or qualitatively not adapted . Until the beginning of the 1980s the stress systems including the sympathetic nervous system SNS and the hypothalamic-pituitary-adrenal axis were thought to play a proinflammatory role by supporting the immune response. This view was markedly changed in the years thereafter when targeted experiments with .
