Detailed Description:

CRPS, a chronic pain syndrome associated with trophic disturbances is a frequent complication after limb trauma. More than one third of the CRPS will continue to chronic disease including loss of function in one limb. Some reports implicate an autoimmune pathogenesis of CRPS. Especially the finding of autoantibodies against peripheral neurons and successful treatment in single cases provide evidence for a possible successful treatment of CRPS with intravenous immunoglobulins (IvIg). Therefore IvIg may be an important anti-inflammatory treatment to prevent severe chronification of CRPS. Since IvIg is mainly effective in B-cell-mediated autoimmune diseases, autoantibodies against autonomic neurons and the concentration of B-cell activating factors BAFF and APRIL will be measured in the course of the study.
