Nonglycemic and Glycemic Risk Factors for Painful Neuropathic Symptoms and for Distal Symmetrical Polyneuropathy (DSPN) in the Diabetes Prevention Program/Diabetes Prevention Program Outcomes Study.

ABSTRACT:

Objective

The clinical presentation, symptoms, and signs of neuropathy vary substantially. We determined whether painful neuropathic symptoms and distal symmetrical polyneuropathy (DSPN) were associated with different risk factors in a longitudinal study of Diabetes Prevention Program/Diabetes Prevention Program Outcomes Study (DPP/DPPOS) participants.

Research design and methods

We assessed neuropathy in 1,779 DPP/DPPOS participants ∼21 years after DPP randomization. Symptoms were assessed using the Michigan Neuropathy Screening Instrument (MNSI) questionnaire and signs using pinprick, vibration, and monofilament testing. We defined four mutually exclusive neuropathy phenotypes: 1) no symptoms or signs of DSPN, 2) neuropathic pain without signs, 3) other neurologic symptoms
