A New Look at Diabetic Neuropathy

Stephanie Eid, Ph.D., led a research team examining gene expression at two injury sites in peripheral neuropathy to identify new therapy targets, publishing their findings in Translational Research.

“Neuropathy develops clinically in a distal (nerves in the toes, for example) to proximal (nerves in the legs and thighs) manner,” explained Frances and Kenneth Eisenberg Emerging Scholar Stephanie Eid, Ph.D. This study found that this clinical presentation (distal-to-proximal) is associated with different gene expression signatures at different injury sites.”

When looking at gene expression profiles, they found that specific pathways related to the body’s defense system, inflammation, or how it processes sugar and fat were similarly disrupted at distal and proximal sites. However, some of these disruptions were unique to specific areas of nerve injury, demonstrating that nerve damage in peripheral neuropathy can vary depending on location.  Together, these findings indicate that different nerve locations are associated with unique changes in gene expression, which will ultimately impact mechanism-based therapeutic interventions.

Diabetic teens with high blood sugar have higher neuropathy risk in adulthood

Poor blood sugar control in adolescence increases the risk of painful future complications for people with type 1 diabetes, research suggests. Participants with the greatest increase in HbA1c levels from childhood to adolescence not only retained higher blood sugar levels in adulthood, but they also had a greater risk for neuropathy.

Research by Andrea and Lawrence A. Wolfe Research Professor Melissa Elafros, M.D., Ph.D., found that though it is a widespread disorder, neuropathy often goes undiagnosed, new research shows, leaving many people at risk of falls, infection, and even amputation.

Neuropathy common, and mostly undiagnosed, among patients in this Michigan city

A research team, led by Michigan Medicine and in partnership with Hurley Medical Center, finds that nearly three-quarters of patients at a clinic in Flint, Mich., a community that is predominantly Black and socioeconomically disadvantaged, had neuropathy — of which 75% was undiagnosed.
