Neuregulin-4 (Nrg4) is a novel adipokine associated with obesity, hyperglycemia, insulin resistance, dislipidemia, inflammation, and oxidative stress in mice and humans. However, no report has demonstrated the relationship of circulating Nrg4 with diabetic peripheral neuropathy (DPN). The objective of our study was to investigate the relationship between circulating Nrg4 and DPN in a cross-sectional study. Circulating Nrg4 levels were determined with an enzyme-linked immunosorbent assays kit in 132 newly diagnosed type 2 diabetes mellitus (nT2DM) patients and 41 normal controls (NC group). The associations of circulating Nrg4 with other parameters were also analyzed. Circulating Nrg4 levels were significantly lower in nT2DM patients with no DPN than in NC subjects, and were further markedly decreased in nT2DM patients with DPN (P < 0.01 or P < 0.05). Circulating Nrg4 levels were progressively decreased with an increasing number of abnormal DPN screening (P for trend < 0.01). Circulating Nrg4 levels correlated negatively with 8-iso-prostaglandin F-2 alpha (8-iso-PGF(2 alpha)), high-sensitivity C-reactive protein (hs-CRP) and vibration perception threshold (VPT) (all P < 0.01), and 8-iso-PGF(2 alpha), hs-CRP, glycated hemoglobin A1c and VPT were independently related factors to circulating Nrg4 in nT2DM patients (P < 0.01 or P < 0.05). Moreover, circulating Nrg4 was significantly associated with the development of DPN even after controlling for anthropometric, biochemical and clinical parameters. Additionally, the analysis of receiver operating characteristic curves revealed that the best cutoff value for circulating Nrg4 to predict DPN was 1.58 ng/mL (sensitivity 90.91%, specificity 54.55%, and area under the curve 0.716). These findings together suggested that circulating Nrg4 levels were reduced in DPN patients and Nrg4 may be a novel adipokine associated with inflammation, oxidative stress, and long-term glycemic control in nT2DM patients.
