We want to study whether MRI can be useful in diagnosing and monitoring patients with CIDP in maintenance treatment with immunoglobulin

Chronic Inflammatory Demyelinating Polyradiculoneuropathy

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • DTI changes in nerves and muscles [ Time Frame: At enrolment ]
    Diffusion Tension Imaging (DTI) in peripheral nerves and muscles in the lower extremities in CIDP patients treated with SCIG will be compared to healthy controls

Secondary Outcome Measures:
  • Changes in MRI findings between treated and untreated CIDP patients [ Time Frame: All patients are examined at enrolment. Untreated patients are re-examined after 4 months of treatment ]

    Comparing changes in MTR and DTI between CIDP patients treated with subcutaneous immunoglobulin to those untreated.

    The untreated patients will be examined again after 4 months of treatment with immunoglobulin

  • Comparing clinical findings to MRI [ Time Frame: At enrolment ]

    Clinical evaluation by:

    Isokinetic dynamometry Clinical MRC score

    These findings wil be compared to findings on MRI to assess an eventual correlation

Enrollment: 39
Study Start Date: May 2014
Study Completion Date: May 2016
Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
CIDP - treated
Patients diagnosed with CIDP and fulfilling the criteria by EFNS and PNS and in maintenance treatment with subcutaneous immunoglobulin
Healthy controls
Healthy, gender and age matched controls
CIDP - untreated
Patients newly diagnosed with CIDP and untreated are treated with immunoglobulin and re-examined after 4 months of treatment

Detailed Description:

Chronic inflammatory neuropathies such as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) can be successfully treated with immunoglobulin either intravenously (IVIG) or subcutaneously (SCIG).

CIDP is diagnosed by electrophysiology which is time-consuming and unpleasant for the patient.

New techniques suggest that Magnetic Resonance Imaging (MRI) and ultrasound imaging can be used to detect injuries in the peripheral nerves

We want to study if MRI and ultrasound is able to detect damages in peripheral nerves, nerve roots and plexus in patients with CIDP.

Moreover, we want to compare these findings to healthy matched controls and to see if treatment with immunoglobulin changes findings in MRI


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All

  • No neurological disorders

Exclusion Criteria:

  • Age < 18 or > 80 years
  • Contraindications to MRI
  • Pregnancy
  • Other cause of neuropathy (incl. pressure neuropathy)
