Abstract:
Objective:To analyze the diagnostic value of Michigan nerve screening Scale (MNSI), pain, touch and temperature detection combined with vibratory perception threshold (VPT) in diabetic peripheral neuropathy (DPN).Methods:A total of 500 patients with type 2 diabetes mellitus (T2DM) who received inpatient treatment in Xinhua Hospital Chongming Branch Affiliated of Shanghai Jiao Tong University School of Medicine from January to December 2018 were selected. Sixty four patients with DPN were enrolled in the DPN group, and the remaining 436 patients were enrolled in the no-DPN group. The clinical data and the results of MNSI scale, pain, touch and temperature detection thresholds and VPT of the two groups were compared. Receiver operating characteristic (ROC) curve was drawn to analyze the clinical value of single and combined examination indicators in the diagnosis of DPN.Results:MNSI symptom questionnaire score and MNSI physical examination score in DPN group were higher than those in no-DPN group: (3.00 ± 1.35) scores vs. (1.69 ± 0.52) scores, (1.57 ± 0.50) scores vs. (1.01 ± 0.24) scores; the proportion of touch regression, pain regression and temperature regression was significantly higher than that in no-DPN group; and the levels of VPT in the DPN group was higher than that in the no-DPN group: (26.34 ± 5.03) V vs. (17.97 ± 6.82) V, there were statistical differences ( P<0.01). When the single index was diagnosed, the area under the curve (AUC) value of VPT was the highest (0.825), and significantly higher than the pain, touch and temperature detection ( P<0.01). The AUC value of VPT + MNSI in combined diagnosis was the highest (0.738), and the sensitivity and specificity of DPN diagnosis were 51.56% and 96.10%, respectively. Conclusions:Compared with MNSI scale score, sensory detection such as pain, touch and temperature, VPT has the best diagnostic efficiency for DPN, while combined with MNSI, the specificity can be further improved, but the sensitivity decreases, which is worthy of clinical attention.
