血清25(OH)D3水平与2型糖尿病患者周围神经病变的相关性

目的探究血清25羟维生素D3〔25(OH)D3〕与2型糖尿病患者周围神经病变的相关性。方法 2型糖尿病患者120例,根据患者病情分为单纯糖尿病组(A组)50例和糖尿病合并周围神经病变组(B组)70例,收集患者临床资料,检测血清25(OH)D3水平与四肢末梢神经传导功能。以周围神经病变为因变量,年龄、病程、血清25(OH)D3含量、糖化血红蛋白、空腹C肽为自变量进行Logistics回归分析。结果两组患者临床资料对比,B组年龄、病程、糖化血红蛋白高于A组(P<0.05),空腹C肽低于A组(P<0.05)。Logistic逐级回归分析结果显示,25(OH)D3、空腹C肽同周围神经病变呈负相关(P<0.05)、年龄、病程、糖化血红蛋白与周围神经病变呈正相关(P<0.05)。结论 25(OH)D3的水平变化对糖尿病并发症周围神经病变的发生具有较大影响,糖尿病患者适度补充25(OH)D3可在某种程度上预防周围神经病变的发生。

Gastric Emptying in Patients with Insulin-Requiring Diabetes Mellitus

Gastric emptying of technetium labeled liquid and solid meals were studied in a group of long-standing, insulin-requiring male diabetics to evaluate the relationship of gastroparesis to symptoms, diabetic control, and diabetic complications. Control subjects and three groups of diabetics were studied: A) no neuropathy; B) peripheral neuropathy; and C) peripheral and autonomic neuropathy. Nine diabetics had gastrointestinal symptoms. Gastric t1/2 liquid emptying was similar in all groups and in controls, but liquid gastric emptying in the first 15 min was significantly more rapid in the diabetics than controls. Solid emptying was prolonged in group C patients. There was a significant correlation between t1/2 solid emptying and the severity of neuropathy. The eight patients with slow solid emptying had more neuropathy and gastrointestinal symptoms than the remaining 22 patients. The type and duration of diabetes, diabetic control, and frequency of retinopathy are independent of gastroparesis. These data indicate that delayed emptying of solids is common (27%) in patients with clinically detectable neuropathy and may often be asymptomatic. Visceral autonomic neuropathy seems the most important underlying factor in diabetic gastroparesis.     

Peripheral neuropathy is associated with increased serum levels of uric acid in type 2 diabetes mellitus

We assessed serum uric acid (SUA) levels in patients with type 2 diabetes mellitus (T2DM) with or without peripheral neuropathy (diagnosed by the Neuropathy Disability score [NDS]). We enrolled 64 patients with T2DM with peripheral neuropathy (group A: 31 men, mean age 63.0 ± 2.8 years) and 66 age-, gender-, renal function- and T2DM duration-matched patients without neuropathy (group B: 32 men, mean age 62.4 ± 3.1 years). Serum uric acid was significantly higher in group A (P < .001). There was a significant correlation between SUA and NDS in both groups (group A: r(s) = .93, P < .001; group B: r( s) = .95, P < .001). C-reactive protein (CRP) was also significantly higher in group A (P < .001) and correlated significantly with SUA in both groups (group A: r(s) = .93, P < .001; group B: r(s) = .87, P < .001). Serum uric acid is increased in patients with T2DM with neuropathy versus those without. Whether SUA is involved in the pathogenesis of T2DM peripheral neuropathy remains to be established.

妊娠中期妇女血清尿酸水平与25羟维生素D3的关系

目的 探讨妊娠中期妇女血清尿酸水平与25羟维生素D₃[25(OH)VD₃]的关系。方法 选取妊娠中期妇女221例,收集其年龄、妊娠周期等一般资料,检测其肝、肾功能、空腹血糖(FPG)、甲状腺功能及25(OH)VD₃水平,并根据25(OH)VD₃水平将其分为维生素D缺乏组 [25(OH)VD₃＜50nmo/L]和维生素D适宜组[25(OH)VD₃≥50nmol/L],比较两组患者的临床资料,并对影响25(OH)VD₃水平的因素进行分析。结果 221例妊娠中期妇女中,147例（67%）存在维生素D缺乏,74例（33%）维生素D适宜。维生素D缺乏组妊娠周期、血清尿酸、促甲状腺激素（TSH）水平均低于维生素D适宜组,游离甲状腺素（FT₄）、FPG和总胆红素（TBIL）水平均高于维生素D适宜组,差异有统计学意义（P<0.05）。相关性分析结果显示,妊娠中期妇女25(OH)VD₃水平与妊娠周期、血清尿酸、TSH呈正相关,与FT₄、TBIL呈负相关（P<0.05）。Logistic回归分析结果显示,妊娠中期妇女血清尿酸水平降低是25(OH)VD₃缺乏的危险因素（OR=1.008,P=0.024）。结论维生素D缺乏在妊娠中期妇女中较为常见,妊娠周期、血清尿酸、FT₄、TSH及TBIL与妊娠中期妇女的25(OH)VD₃相关,其中血清尿酸水平降低是25(OH)VD₃缺乏的主要危险因素。     

An insertion/deletion polymorphism in the alpha2B adrenoceptor gene is associated with peripheral neuropathy in patients with type 2 diabetes mellitus.

Alpha2B adrenoceptor (alpha2B-AR) mediates a variety of functions in humans. An insertion/deletion (I/D) polymorphism of the alpha2B-AR gene located on chromosome 2 has been described. The aim of the present study was to investigate the potential association between alpha2B gene I/D polymorphism and peripheral neuropathy in Greek patients with type 2 diabetes mellitus. The study included 130 patients (70 men) with diabetic neuropathy (group A) and 60 patients (34 men) without diabetic neuropathy (group B). There was no difference in age, gender and diabetes duration between the groups. Diabetic neuropathy was diagnosed by clinical examination using the Diabetic Neuropathy Index (DNI). Genotyping of I/D polymorphism was performed by PCR. Frequency of the D allele was significantly higher (p=0.001) in group A (26.9%) as compared to group B (11.7%). DNI score differed significantly (p=0.001) between the three genotype groups (I/I, I/D, D/D). It was significantly higher (p=0.04) in patients with I/D (3.7+/-1) than in those with I/I (2.5+/-0.9) and significantly higher (p=0.001) in patients with D/D (5.6+/-1.3) than in those with I/D (3.7+/-1). CONCLUSIONS: Patients with neuropathy exhibit a significantly higher frequency of the D allele in comparison to those without neuropathy. Presence of the D allele is also associated with a higher neuropathic score. These results provide evidence for an association of the D allele with both presence and severity of neuropathy in patients with type 2 diabetes mellitus.     

Intestinal transit in insulin-requiring diabetics

Intestinal transit was assessed in 25 insulin-requiring male diabetics and 15 healthy controls by measuring the breath hydrogen appearance time after the ingestion of both the liquid and the solid meal containing non absorbable carbohydrate. Three groups of patients were studied: A) nine patients without peripheral or autonomic neuropathy or retinopathy; B) nine patients with peripheral neuropathy; and C) seven patients with peripheral and autonomic neuropathy. Eight patients complained of gastrointestinal symptoms, including three with watery diarrhea. Intestinal transit of the solid meal was more prolonged than the liquid meal in normal and diabetic subjects. There was no significant difference in intestinal transit between normal controls and any group of diabetics; however, one-third of the diabetics had abnormal intestinal transit of the liquid test meal (four rapid, four delayed); only one patient with diarrhea had rapid intestinal transit. These data suggest that abnormal intestinal transit is common in diabetics. Altered intestinal transit is not a prerequisite of diabetic diarrhea.
