Role of therapeutic plasmapheresis in chronic inflammatory demyelinating polyneuropathy.
Therapeutic plasmapheresis is an effective therapy in the management of CIDP. A varying percentage of patients, approximately 30 to 60%, may benefit from the treatment. The optimal frequency and volume of PE need to be clarified, but, taking into account the heterogeneity of the disease, a too rigid approach should be avoided. According to our experience, neither morphological findings on sural nerve biopsy, nor conduction slowing, conduction block, or the amount of spontaneous activity on needle electromyography in a weak muscle correlated clearly with the later outcome of PE. Possibly our patient number is too small to provide any statistically significant predictor of outcome. In our opinion it is essential to combine plasmapheresis with effective immunosuppression to avoid a rebound with overshooting synthesis of putative pathogenic antibodies or factors. Finally, IA with T-PVA columns has proven effective in single, case-controlled patients with CIDP. It may be a promising supplement to PE avoiding the need and risks of protein replacement.
