NCT02372149

Brief Summary

The purpose of this study is to determine whether intravenous immunoglobulin (IVIg) is an effective intervention for patients with diabetes, peripheral neuropathy, and demyelination on nerve conduction studies. All patients will receive both IVIg and placebo for 3 months each, with a 3 month washout period in between.

    Baseline and 3 months

  • Change in Nerve Conduction Studies (NCS) after 3 months

    Baseline and 3 months

  • Change in Medical Research Council (MRC) Sum Score after 3 months

    Baseline and 3 months

  • Change in Grip Strength after 3 months

    Baseline and 3 months

  • Change in Short Form 36 (SF-36) Quality of Life after 3 months

    Baseline and 3 months

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 years.
  • Diabetes, as per American Diabetes Association Criteria.
  • Clinical evidence of polyneuropathy and NCS shows 2 separate motor nerves (median, ulnar, tibial, or peroneal) which meet criteria for demyelination, defined as follows:
  • Conduction velocity \<90% lower limit of normal (LLN), distal latency \>110% upper limit of normal (ULN), or minimal F-wave latency \>110% ULN
  • The changes are not exclusively due to median neuropathy at the wrist, ulnar neuropathy at the elbow, or peroneal neuropathy at the fibular head.
  • Clinical suspicion of possible demyelinating polyneuropathy (CIDP).

You may not qualify if:

  • Pregnant patients, or those of childbearing potential not using contraception.
  • Patients \<18 years of age.
  • Presence of an alternative etiology of peripheral neuropathy, such as: hereditary neuropathies (Charcot Marie-Tooth disease); B-vitamin deficiency- or excess-related neuropathy; uremic neuropathy; neuropathy secondary to monoclonal gammopathy; history of cancer- or chemotherapy-related neuropathy; other toxin exposures; and alcoholic neuropathy.
  • Contraindication to IVIg, including: history of recurrent thrombosis, immunoglobulin A deficiency, or severe hypersensitivity reaction to IVIg in past, renal failure, recurrent deep venous thrombosis, pulmonary embolus, stroke, or myocardial infarction.
  • Presence of serious or unstable medical condition, which may preclude study completion or lead to inability to tolerate IVIg. This may include active heart failure, uncontrolled hypertension, or severe anemia, among other conditions.
  • Presence of concomitant neurological illness, which may confound evaluation.
  • Fails or unable to provide informed consent.
