Abstract BackgroundThe clinical characteristics and outcomes of small fibre neuropathy (SFN) in Chinese patients with type 2 diabetes have not been thoroughly described, and we investigated metabolic and neurological indexes and the prognosis of type 2 diabetic patients based on skin biopsy. MethodsThirty-four healthy Chinese volunteers were recruited for skin biopsy to establish the reference range of intraepidermal nerve fibre density (IENFD). Eighty-nine patients with type 2 diabetes from the Department of Endocrinology at Nanjing Drum Tower Hospital between December 2015 and April 2020 were included in the final study. Metabolic and neurological indexes were evaluated at baseline. Diabetic cardiovascular autonomic function was tested through cardiovascular autonomic reflex tests (CARTs). Seventeen pure SFN subjects and 9 mixed diabetic polyneuropathy (DPN) subjects were reassessed after the follow-up. ResultsLevels of HbA1c and postprandial blood glucose were lower (P=0.005 and P=0.041, respectively), while postprandial C-peptide and insulin were higher (P=0.001 and P=0.019, respectively) in the pure SFN group than in the mixed DPN group. Regarding the CARTs, the mixed DPN group obtained the highest score, indicating the worst cardiovascular autonomic neuropathy (CAN). Among the four CART items, postural BP change was lower while deep breathing max-min was higher in the pure SFN group than in the mixed DPN group (P=0.023 and P=0.040, respectively). A partial correlation showed that there was a negative correlation between IENFD of the distal leg and CART scores (r=-0.513, P=0.001) after adjusting for age and duration of diabetes. Only vitamin B12 (p=0.028) and motor nerve conduction velocity (MCV) of the common peroneal nerve (p=0.045) were increased in the 17 patients with pure SFN after the follow-up. However, MCVs of the common peroneal nerve (p=0.025) and tibial nerve (p=0.047) were decreased at the final visit in the mixed DPN group. ConclusionsBetter islet function and cardiovascular autonomic function were observed in patients with pure SFN compared with mixed DPN. CART scores were negatively correlated with IENFD in the distal leg even after adjusting for age and duration of diabetes. The metabolic and neurological indexes remained relatively stable in the follow-up of pure SFN subjects.

Background: Diabetes mellitus (DM) is a disorder with a debilitating effects on cardiac autonomic control. Multiple major cardiovascular risk factors associated with DM led diabetic patients at high risk of Cardiovascular Disease. Objective: To assess cardiovascular responses to tilting in Type 2 Diabetic patients (T2DM) with normal and abnormal autonomic function test. Methods: This experimental study was conducted on 60 patients of T2DM. Among them, 30 patients were with normal cardiovascular reflex test (group DN) and 30 patients were with abnormal test (group DA). Thirty(30) apparently healthy subjects with similar age and sex without any physical illness were enrolled as control. Tilt table test of all subjects was done by tilting at 60° for 10 min by using a motorized tilt table. Cardiovascular response to tilt test was assessed by calculating D Heart rate (Acceleration index and Brake index); DSBP (SBP 30s-0 and SBP1 min -0), DDBP (DBP 30s-0 and DBP1 min -0) after tilting. For statistical analysis, one-way ANOVA followed by Bonferroni post hoc was used. Results: In this study, the Acceleration index was significantly higher in patient group DN compared to control and DA(p<0.001). But the Brake index was significantly (p<0.01, p<0.05) lower in both group of patients compared to control. In addition, SBP 30sec-0 and SBP1 min-0 were significantly higher in DA than those of control and DN.DBP 30sec-0 and DBP1min-0 were significantly (p<0.001) lower in DA patients compared to DN and control. Conclusion: This study concluded that cardiovascular response to tilting was weak in T2DM patients and it was greatly affected in T2DM patients with abnormal autonomic function test.

Abstract. Background: to evaluate the effects of Vitamin D3 on glyco-metabolic control in type 2 diabetic patients with Vitamin D deficiency. Methods: one hundred and seventeen patients were randomized to placebo and 122 patients to Vitamin D3. We evaluated anthropometric parameters, glyco-metabolic control, and parathormone (PTH) value at baseline, after 3, and 6 months. Results: a significant reduction of fasting, and post-prandial glucose was recorded in Vitamin D3 group after 6 months. A significant HbA1c decrease was observed in Vitamin D3 (from 7.6% or 60 mmol/mol to 7.1% or 54 mmol) at 6 months compared to baseline, and to placebo (p < 0.05 for both). At the end of the study period, we noticed a change in the amount in doses of oral or subcutaneous hypoglycemic agents and insulin, respectively. The use of metformin, acarbose, and pioglitazone was significantly lower (p = 0.037, p = 0.048, and p = 0.042, respectively) than at the beginning of the study in the Vitamin D3 therapy group. The units of Lispro, Aspart, and Glargine insulin were lower in the Vitamin D3 group at the end of the study (p = 0.031, p = 0.037, and p = 0.035, respectively) than in the placebo group. Conclusions: in type 2 diabetic patients with Vitamin D deficiency, the restoration of value in the Vitamin D standard has led not only to an improvement in the glyco-metabolic compensation, but also to a reduced posology of some oral hypoglycemic agents and some types of insulin used.
