Diabetic peripheral neuropathy (DPN) was found to be more commonly diagnosed among patients with liver steatosis or fibrosis, according to the results of a study published in the Journal of Diabetes Investigation.

Researchers gathered demographic data and clinical characteristics for patients (N=520; 43.6% men) with type 2 diabetes and assessed liver health and symptoms of DPN. The mean age of participants was 65 years, mean body mass index was 24.47  kg/m2, and mean glycated hemoglobin (HbA1c) was 7.01%.

Most patients (63.0%) had liver steatosis and 18.1% had liver fibrosis. Patients with liver steatosis were heavier, had a shorter duration of diabetes, and had higher fasting insulin and C-peptide levels, as well as systolic and diastolic blood pressures (all P <.001). Patients with liver fibrosis were more likely to be women (P =.004), to be heavier (P =.03), to have higher HbA1c (P =.01), and to have higher systolic (P =.001) and diastolic (P =.001) blood pressure values.

Most patients had DPN (52.1%). Patients with DPN were more likely to be men (P <.001), younger (P =.02), heavier (P =.001), to have higher HbA1c (P <.001), and to have higher systolic (P <.001) and diastolic (P <.001) blood pressure values. Indicators of kidney, liver, and inflammatory health did not differ on the basis of DPN.

A diagnosis of DPN was made more often among patients with liver steatosis vs those without (55.7% vs 44.9%; P =.03) and among those with liver fibrosis vs those without (61.5% vs 50.0%; P =.04).

In the fully adjusted multivariate analysis, liver fibrosis was significantly associated with DPN (adjusted odds ratio [aOR], 2.24; 95% CI, 1.11-4.53; P =.02) but liver steatosis was not (aOR, 1.78; 95% CI, 0.97-3.25; P =.06).

A limitation of this study is its cross-sectional design; therefore, causal relationships could not be determined.

These data indicate that DPN was more prevalent among patients with liver fibrosis and steatosis and that fibrosis was an independent predictor of DPN.
