The aim of this study is to quantify the effect of IVIG treatment in a group of patients with
chronic inflammatory demyelinating polyradiculoneuropathy(CIDP), who requires continues
treatment of IVIG at regular intervals of 3-10 weeks:
1. During continues treatment of IVIG at regular intervals of 3-10 weeks.
2. During pause in treatment.
Hypothesis:
1. The disease activity in the patients are cyclical correlating to the treatment
intervals.
2. Pause in treatment will increase disease activity, which can be quantified with symptom
scores, disability scales, and clinical test.
Primary effect parameter is muscle strength quantified by isokinetic dynamometry.
Added to the protocol there is an immunological study of inflammatory markers in blood
samples of patients under treatment pause.
