白介素18基因型及血清水平与2型糖尿病肾病的相关性

目的研究白介素18（IL-18）基因型及血清水平与2型糖尿病肾病（DN）的关系。方法采用聚合酶链反应-限制性片段长度多态性（PCR-RFLP）技术,检测360例2型糖尿病患者（160例伴DN）及180名正常对照组的IL-18的基因多态性,同时采用酶联免疫吸附试验（ELISA）检测血清IL-18水平。结果与对照组比较,糖尿病肾病组血清IL-18水平显著高于对照组（P〈0．01）。IL-18基因-137G／C多态性在两组人群中的分布差异有统计学意义（P〈0．05）,携带-137C等位基因的糖尿病肾病患者血清IL-18水平显著高于不携带者（P〈0．05）。结论IL-18基因-137G／C多态性与DN的发病可能具有相关性,其中C等位基因可能是DN发病的遗传易感基因;携带C等位基因的个体可能通过促进IL-18的高度表达进而增加了DN的发病风险。

Lack of an association of urinary albumin excretion with interleukin-6 or C-reactive protein in patients with type 2 diabetes

The reason for the elevation of fibrinogen concentration in diabetic patients with nephropathy is not known so far. In order to elucidate the mechanism of such an increase in fibrinogen levels, we investigated haemorheological and inflammatory markers in type 2 diabetic patients in a cross-sectional design. Thirty-two non-smoking type 2 diabetic patients (13 women, 19 men; body mass index 29.1±5.4 kg/m², age 62.8±12.1 years) were investigated. Patietns with C-reactive protein levels > 1.5 mg/dl were excluded from the study. Concentration of fibrinogen was measured by immunonephelometry, C-reactive protein by immunoturbidimetry, and interleukin-6 (IL-6) by an enzyme-linked immunosorbent assay, and viscosity of plasma and of whole blood was determined by rotation viscosimetry. Concentrations of inflammatory parameters were well correlated with each other (p<0.05 for all correlations): IL-6 with C-reactive protein (r=0.48), and C-reactive protein with fibrinogen (r=0.41). While no associations were found with concentrations of C-reactive protein or IL-6, urinary albumin excretion was correlated with erythrocyte sedimentation rate (r=0.47) and with fibrinogen concentration (r=0.39; p<0.05). In patients with type 2 diabetes mellitus, urinary albumin excretion was not associated with concentrations of IL-6 or C-reactive protein. These results suggest an IL-6-independent mechanism for increased fibrinogen levels and erythrocyte sedimentation rate in type 2 diabetic patients with increased urinary albumin excretion.

Association of C-reactive protein and hyperuricemia with diabetic nephropathy in Chinese type 2 diabetic patients

To investigate the relationship of micro-albuminuria with C-reactive protein (CRP) and hyperuricemia in Chinese patients with type 2 diabetes. All patients with type 2 diabetes, 40 years old and over were recruited consecutively from diabetic clinics at a medical center. Serum lipid, creatinine, uric acid, CRP, HbA_1C and urinary albumin concentration were measured. A total of 515 patients, aged 60.3 ± 10.7 years were recruited and the number (rate) of micro- and macro-albuminuria were 109 (21.2%) and 55 (10.7%). The prevalence of micro-albuminuria for the quartiles of CRP levels demonstrated a meaningful trend of increases between groups from 17.4, 21.1, 30.3, and 31.2% (P trend = 0.002). Besides, the median CRP concentrations was significantly higher in the patients with micro- and macro-albuminuria than those with non-albuminuria. Stepwise logistic regression analysis revealed that CRP was significantly associated with abnormal albuminuria (OR = 1.36, 95% CI = 1.12–1.64, P = 0.002). After excluding those subjects with angiotensin-converting enzyme inhibitors/angiotension II receptor blockers or/and statin usage, the observed relationship between serum CRP levels and albuminuria was still persistent (OR = 1.61, 95% CI = 1.24–2.08, P < 0.001). In addition, hyperuricemia were significantly associated with abnormal albuminuria in the patients without diuretics, uricosuric agents or alcohol usage. Both serum CRP levels and hyperuricemia were significantly related to the presence of albuminuria in patients with diabetes. In addition, Chinese type 2 diabetic patients with serum CRP levels in the lower range as other ethnic groups can lead to the development of micro-albuminuria.     

Urinary excretion of glycated albumin in insulin-dependent diabetic patients with normal urinary albumin excretion

Summary Glycation involves both circulating proteins, such as albumin, and structural proteins, such as the components of the glomerular basement membrane. A preferential excretion of glycated albumin (more anionic at physiological pH compared with unmodified plasma albumin) has been reported by some authors, but not by others. We therefore investigated the selectivity index (renal clearance of non-glycated albumin/clearance of glycated albumin) in 25 insulin-dependent diabetic patients with normal urinary albumin excretion and in 19 well-matched control subjects. The selectivity index was significantly higher in diabetic patients than in control subjects: 1.38±0.05 SEMvs 0.98±0.02, p<0.0001. This result is not consistent with a preferential urinary excretion of glycated albumin, at least in normoalbuminuric uncomplicated insulin-dependent diabetic patients.     

尿转铁蛋白排泄率测定对糖尿病肾病早期诊断的意义

应用免疫速率散射比浊法测定５２例健康人和７６例无临床蛋白尿的糖尿病患者２小时尿微量白蛋白（Ａｌｂ）和微量转铁蛋白（ＴＲＦ）的排泄率（ＡＥＲ和ＴＥＲ）。结果：１．糖尿病组ＡＥＲ和ＴＥＲ均明显高于正常对照组（Ｐ＜０．０１）。２．在糖尿病组中，３２．９％的患者ＡＥＲ升高，４３．４％的患者ＴＥＲ升高，两者有显著性差异（Ｐ＜０．０１）。ＴＥＲ和ＡＥＲ呈明显正相关（ｒ＝０．９３，Ｐ＜０．０１）。３．在ＡＥＲ升高和ＴＥＲ升高糖尿病组中，其血压分别稍高于ＡＥＲ正常糖尿病组和ＴＥＲ正常糖尿病组，差异有显著性意义（Ｐ＜０．０５），而空腹血糖水平无此变化（Ｐ＞０．０５）。与无视网膜病变组相比，有视网膜病变组ＡＥＲ、ＴＥＲ升高的阳性率增加，两者有显著性差异（Ｐ＜０．０５）。提示：ＴＥＲ做为糖尿病肾病早期诊断指标，可能与ＡＥＲ具有相同的意义，甚至较其敏感。     

2型糖尿病患者脂蛋白(a)水平与尿白蛋白排泄率的关系

许多研究发现糖尿病肾病 (ＤＮ )的尿白蛋白排泄率(ＵＡＥＲ)与血浆脂蛋白 (ａ)〔Ｌｐ(ａ)〕水平存在正相关 ,因此推测Ｌｐ(ａ)为糖尿病肾病的危险因子〔1〕;但是Ｊｅｎｎｋｉｎｓ认为ＤＮ患者白蛋白丢失过多 ,可导致Ｌｐ(ａ)水平上升〔2〕。因此 ,糖尿病肾病患者高Ｌｐ(ａ)浓度是肾病的危险因素 ,还是肾病的伴随现象目前尚不十分清楚。辛伐他汀为羟甲基戊二酰辅酶Ａ抑制剂类降脂药 ,有报道认为能降低糖尿病患者的Ｌｐ(ａ)水平〔3〕;本研究观察辛伐他汀改变血浆Ｌｐ(ａ)水平是否影响ＵＡＥＲ的变化 ,探讨ＤＮ的病因。一、对象和方法1.研究对…     

Pentoxifylline,total urinary protein excretion rate and arterial blood pressure in long-term insulin-dependent diabetic patients with overt nephropathy

Summary A specific hemorheologic treatment might reduce urinary protein excretion and the decline in kidney function in diabetic patients with overt clinical nephropathy. Twenty-one insulin dependent (type I) diabetic patients were randomized and assigned to a treatment with conventional antihypertensive therapy (protocol I) or with pentoxifylline (Trental 400^?) (protocol II). A marked improvement of blood rheology pattern, together with a reduction of urinary albumin excretion rate and total urinary protein excretion rate, was demonstrated throughout a 1-year follow-up study with pentoxifylline. Furthermore a decrease of systolic and diastolic blood pressure levels was found during the treatment. The modification of these parameters was followed by a significant increase of creatinine clearance in each of the patients studied. The results obtained during pentoxifylline therapy were comparable to those obtained in patients treated with conventional antihypertensive drugs. Pentoxifylline may therefore be used in the treatment of advanced nephropathy in diabetic patients.
