Diabetic sensorimotor polyneuropathy (DSP) is a common complication of both type 1 and type 2 diabetes mellitus (DM) and is thought to occur due to hyperglycemia-related peripheral nerve Inhibitors,research,lifescience,medical damage. Classically, DSP results in axonal degeneration and progressive loss of nerve fibers, as indicated by reduced compound muscle action potential (CMAP) and sensory nerve Inhibitors,research,lifescience,medical action potential (SNAP) amplitudes, with normal or slightly reduced conduction velocities secondary to loss of the largest, fastest conducting axons (Behse et al.
1977; Dyck et al. 1986). For this reason, diabetes patients who have changes suggestive of demyelination on nerve conduction studies (NCS) are usually Inhibitors,research,lifescience,medical considered to have a superimposed immune-mediated polyneuropathy, such as chronic inflammatory demyelinating polyneuropathy (CIDP) (Van den Bergh et al. 2010). However, NCS changes suggestive of demyelination, such as conduction velocity slowing, have been demonstrated recently in patients with DSP and found to be related to glycemic control in those with type 1 diabetes (Dunnigan et al. 2013). Thus it becomes important to distinguish DSP from CIDP in diabetes patients Inhibitors,research,lifescience,medical as the latter may be amenable to treatment. Immunomodulatory therapies, including intravenous immunoglobulin (IVIg), corticosteroids, and plasma exchange can be effective treatments for CIDP in diabetes patients even in the presence of an underlying DSP (Van den Bergh et al. 2010; Latov 2011). We sought to compare the clinical and JNK-IN-8 research buy electrodiagnostic Inhibitors,research,lifescience,medical features in patients with mild demyelinating changes in DSP (D-DSP) to those patients with diabetes diagnosed with CIDP (CIDP +
DM). We aimed to determine if diabetes patients with D-DSP have unique profiles when compared to patients with CIDP + DM to allow the use of effective, targeted therapies. Materials and Methods Subjects One-hundred and twenty-three diabetes subjects with polyneuropathy were accrued for this CYTH4 study in the neuromuscular clinic of Toronto General Hospital (TGH) at University Health Network (UHN). DSP subjects with type 1 (n = 27) and type 2 (n = 29) diabetes were seen between 2008 and 2012 as part of an ongoing longitudinal cohort study funded by the Juvenile Diabetes Research Foundation (Operating Grant No. 17-2008-715) and a cross-sectional cohort study funded by the Canadian Diabetes Association (Operating Grant No. OG-3-10-3123-BP). Diabetes subjects with CIDP were seen in clinic for management of their immune-mediated polyneuropathy between 1997 and 2012.
