Summary
The purpose of this study is to determine whether intravenous immunoglobulins are effective
in the treatment of complex-regional pain syndrome.
Clinical Details
Official title: Prospective, Double-blind, Randomised, Placebo-controlled, Cross-over Study to Investigate the Effect of Intravenous Immunoglobulins on Complex Regional Pain Syndrome (CRPS, M. Sudeck)
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: Change in impairment Level SumScore (ISS)
Secondary outcome: Pain disability scoreQuality of life (SF-36) Titer of surface-binding neuronal autoantibodies in the serum Serum concentration of B-cell activating factors BAFF, APRIL
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.
