The relationship between insulin resistance, soluble adhesion molecules E-selectin (sE-selectin), intracellular adhesion molecule-1 (sICAM-1), and vascular adhesion molecule-1 (sVCAM-1), mononuclear cell binding to cultured endothelium, and lipoprotein concentrations were evaluated in 28 healthy, nondiabetic, and normotensive individuals. The mean (+/-SEM) lipid and lipoprotein concentrations were within the normal rage: cholesterol (199 +/- 18 mg/dL); triglyceride (128 +/- 12 mg/dL); low-density cholesterol (127 +/- 8 mg/dL; and high-density cholesterol (47 +/- 3 mg/dL). The results indicated that degree of insulin resistance was significantly correlated with concentrations of sE-selectin (r = 0.54, P < 0.005), sICAM-1 (r = 0.67, P < 0.001), and sVCAM-1 (r = 0.41, P < 0.05). Furthermore, the relationship between insulin resistance and both sE-selectin and sI-CAM-1 remained statistically significant when adjusted for differences in age, gender, body mass index, and all measures of lipoprotein concentrations. Finally, mononuclear cell binding correlated significantly with concentrations of sE-selectin (r = 0.54, P < 0.005) and sICAM-1 (r = 0.47, P < 0.01). These findings raise the possibility that previously described relationships between soluble adhesion molecules in patients with hypertension, type 2 diabetes, and dyslipidemia may be due to the presence of insulin resistance in these clinical syndromes and suggests that insulin resistance may predispose individuals to coronary heart disease by activation of cellular adhesion molecules.

Non-insulin dependent diabetes mellitus (NIDDM) is connected with a higher incidence of macrovascular atherosclerotic disorders. The aim of the study was to detect any difference in levels of "cardiovascular risk factors"--fibrinogen, PAI-1 and inflammation response (documented by an increase of protein of acute phase orosomucoid) and of soluble cytoadhesive molecule sE-selectin and sICAM-1 (as markers of endothelial dysfunction) in blood plasma of 118 patients with NIDDM in comparison to the levels in blood plasma of 59 healthy persons as a control group. We observed higher levels of fibrinogen (fibrinogen level was 3.44 +/- 1.02 g/l in NIDDM pts versus 2.44 +/- 0.55 g/l in control group, p < 0.01) and PAI-1 Ag concentration was 159.7 +/- 110.3 ng/ml in NIDDM pts versus 51.43 +/- 24.64 ng/ml in control group, p < 0.01) together with an increase of acute phase protein orosomucoid as a "inflammatory response marker" (orosomucoid concentration was 0.85 +/- 0.23 g/l in NIDDM pts versus 0.54 +/- 0.18 g/l in control group, p < 0.01) in patients with NIDDM. The increase of these "cardiovascular risk factors" levels will be probably induced by higher activity of inflammatory cytokines IL-1 beta and/or TNF alpha in NIDDM patients, because both are inducers of orosomucoid fibrinogen and PAI-1 synthesis. This hypothesis is also supported by observation of higher levels of soluble cytoadhesive molecules sE-selectin (sE-selectin level was 64.25 +/- 26.8 ng/ml in NIDDM pts versus 46.64 +/- 29.57 ng/ml in control group, p < 0.01) and sICAM-1 (sICAM-1 level was 307.71 +/- 86.2 ng/ml in NIDDM pts versus 255.6 +/- 58.0 ng/ml in control group, p < 0.01) in patients with NIDDM. Both cytoadhesive molecules are produced by endothelial cells which are influenced by IL-1 beta and/or TNF alpha. According to these findings we suppose that an "inflammation" plays an important role in the evolution of atherosclerotic process at NIDDM together with the known influence of glucose and lipid metabolism pathology.

It is hypothesized that adhesion molecules could be an early predictor of coronary artery disease. Therefore we investigated the relationship between the concentrations of soluble forms of adhesion molecules and disturbances of glucose metabolism in 78 men referred for coronary angiography but with no previous history of diabetes. The group consisted of 78 men (mean age, 47.6 +/- 7.0 years; mean body mass index [BMI], 28.4 +/- 3.24 with the symptoms of angina pectoris and positive exercise test. All subjects were given a standard oral glucose tolerance test (OGTT) with glucose and insulin estimations. Fasting plasma concentrations of the soluble (s) forms of E-selectin, intercellular adhesion cell molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and HbA(1c) were also measured. According to the OGTT, 10.2% of the patients (n = 8) fulfilled the criteria for type 2 diabetes mellitus and 44.9% (n = 35) for impaired glucose tolerance (IGT). The highest concentrations of sE-selectin were observed in patients with type 2 diabetes mellitus and were significantly higher in comparison to the group with normal glucose tolerance and IGT. The concentration of sVCAM-1 increased with the progression of disturbances of glucose metabolism and remained the highest in type 2 diabetic patients. sICAM-1 concentration was not significantly different. sE-selectin concentration correlated significantly with fasting glucose (r = 0.23, P =.041), postload glucose (r = 0.39, P =.001), and postload insulin (r = 0.28, P =.023). sVCAM-1 was significantly related to the postload glucose concentration (r = 0.30, P =.009). A significant correlation between sICAM-1 concentration and postload insulin was also observed (r = 0.27, P =.025). This would suggest that hyperglycemia increases sE-selectin and sVCAM-1 in plasma, which reflects excessive formation of atherosclerotic plaques in patients with disturbances of glucose metabolism.

We compared the levels of microparticles, platelet activation markers, soluble cell adhesion molecules, and soluble selectins between hypertensive patients with and without type 2 diabetes and control subjects. Binding of anti-glycoprotein IIb/IIIa and anti-glycoprotein Ib monoclonal antibodies to platelets did not differ significantly between the hypertensive patients and controls, but platelet expression of activation markers (CD62P, CD63, PAC-1, and annexin V) was higher in the hypertensive patients. Platelet-derived microparticle (PDMP) and monocyte-derived microparticle (MDMP) levels were significantly higher in the hypertensive patients than in the controls. Soluble ICAM-1, VCAM-1, P-selectin, and E-selectin levels were also higher in the hypertensive patients, and they were significantly higher in the hypertensive patients with diabetes. After treatment with efonidipine, the levels of PDMPs, CD62P-, CD63-, PAC-1-, and annexin V-positive platelets, sICAM-1, sVCAM-1, sP-selectin, and sE-selectin all decreased significantly. The MDMP levels decreased, and the decrease was significant in the hypertensive patients with diabetes. These findings suggest that administration of efonidipine to hypertension patients with diabetes may prevent the development of cardiovascular complications caused by cell adhesion molecules or activated platelets and monocytes.

Soluble CD14 (sCD14), detectable at high concentrations constitutively present in the circulation, plays a key role in the neutralization of lipopolysaccharide, one of the most potent biologic response modifiers currently recognized and involved in the regulation of the inflammatory cascade. We tested whether circulating sCD14 was linked to inflammatory parameters and to insulin resistance in apparently healthy subjects. Serum sCD14 concentration did not significantly correlate with body mass index (BMI), waist to hip ratio, systolic or diastolic blood pressure, serum glucose, fasting insulin, fasting insulin resistance index [homeostasis model assessment (HOMA)], or serum uric acid among 123 subjects. The association between sCD14 and fasting insulin (r = -0.19, P = 0.08) and between sCD14 and HOMA (r = -0.21, P = 0.06) tended toward statistical significance among men. Unexpectedly, sCD14 correlated positively with fasting triglycerides (TG) in all the subjects (r = 0.22, P = 0.014), and this association was most significant in men (r = 0.34, P = 0.002). After controlling for TG, the relationships between sCD14 levels and fasting insulin (r = -0.25, P = 0.029), HOMA (r = -0.28, P = 0.014), and uric acid (r = -0.30, P = 0.006) were significant in men. Among nonsmoking men (n = 44), sCD14 significantly correlated with waist diameter (r = -0.30, P = 0.03), diastolic blood pressure (r = -0.34, P = 0.022), and HOMA (r = -0.30, P = 0.03). In a multiple linear regression analysis, BMI (P < 0.00001), TG (P = 0.003), and sCD14 (P = 0.04) (but not age, sex, waist, or smoking status) independently contributed to 26% of HOMA variance. A polymorphism of the CD14 gene, a C-to-T transition at bp -159 from the major transcription start site, seems to play a significant role in regulating serum sCD14 levels. In a subsample of 33 healthy subjects, carriers of the T allele were similar (in age, sex, BMI, fat mass, waist to hip ratio, blood pressure, and fasting glucose and insulin levels) to C/C homozygotes. In the former, integrated area under the curve for serum glucose concentrations after an oral glucose tolerance test was significantly lower (P = 0.02), and insulin sensitivity (SI) index (minimal model analysis) significantly higher (P = 0.036), than in C/C homozygotes. Among 32 type 2 diabetic subjects, carriers of the T allele also showed a significantly higher SI index (P = 0.03) and had significantly lower C-reactive protein (P = 0.03) and lower circulating soluble intercellular adhesion molecule-1 concentrations (P = 0.01) than did C/C homozygotes. To our knowledge, this is the first study to suggest an effect of a genetic polymorphism on both SI (healthy subjects and type 2 diabetic patients) and endothelial dysfunction (sICAM-1 levels) in type 2 diabetes mellitus.

Relatives of subjects with type 2 diabetes carry an increased risk for diabetes and cardiovascular disease. Oxidative modification of low-density lipoprotein (LDL) and proinflammatory processes are believed to have central roles in atherogenesis. We have investigated the susceptibility of LDL to oxidation and circulating cell adhesion molecules in healthy, glucose-tolerant adults (aged 18 to 38 years) with (12 men, 2 women) and without (controls; 12 men, 2 women) a parental history of type 2 diabetes. From fasting blood samples, oxidation of LDL was initiated with copper ions and adhesion molecules were measured using immunoassays. Groups were similar with respect to age, body mass index (BMI), blood pressure, plasma glucose, and serum lipids. Resistance of LDL to oxidation was reduced in offspring of parents with type 2 diabetes (time to Vmax, 80.1 +/- 2.2 v 91.4 +/- 2.6 minutes, P =.003). Plasma hydroperoxides did not differ between groups (1.2 +/- 0.1 v 1.1 +/- 0.1 micromol/L). Soluble intracellular adhesion molecule-1 (sICAM1) was elevated in offspring compared with controls (571 +/- 20 v 447 +/- 20 microg/L, P =.0002). Soluble vascular cell adhesion molecule-1 (sVCAM-1) (1,184 +/- 76 v 1084 +/- 56 microg/L, P =.31) and E-selectin (53 +/- 8 v 53 +/- 7 microg/L, P =.98) did not differ between groups. Reduced resistance of LDL to oxidation and increased circulating sICAM-1 in young healthy adult offspring of parents with type 2 diabetes may be intrinsic to increased risk of atherosclerosis in these subjects.

Soluble vascular cell adhesion molecule (sVCAM-1) and soluble intercellular adhesion molecule (sICAM-1) are adhesion molecules that are detectable in the serum of patients with cancer, cardiovascular diseases (CVD), and type 2 diabetes. This report describes enzyme-linked immunosorbent assays (ELISAs) on microplates for sVCAM-1 and sICAM-1. The ELISAs have the sandwich test format; polyclonal antibodies are coated on microwells and a one-step procedure is used in which the serum specimen and detecting antibody are added simultaneously to an antibody-coated well. These assays both use HRP-conjugated sheep anti-mouse-IgG to generate the color for quantification. Sensitivities for detecting sVCAM-1 and sICAM-1 are 49 and 40 ng/ml, respectively. Coefficients of variation for within-day and day-to-day replicate analyses are <10%. Results by these in-house ELISAs for serum sVCAM-1 and sICAM-1 compared well with those obtained with commercial kits from R&D Systems, Inc. (correlation coefficients = 0.98 and 0.99 for sVCAM-1 and sICAM-1, respectively). Reference values for serum sVCAM-1 and sICAM-1 levels were measured in 369 apparently healthy Chinese adults, age 30 to 79 yr. There was no significant effect of gender on the reference values for sVCAM-1 or sICAM-1. Serum sVCAM-1 levels (mean +/- SD) were higher in subjects 60 yr old (625 +/- 126 ng/ml), compared to those <60 yr old (525 +/- 110 ng/ml) (p <0.001). Age did not significantly affect the reference values for serum sICAM-1 levels (mean +/- SD, 249 +/- 86 ng/ml). The authors believe that these simple, inexpensive ELISAs will be useful for assessing the risks for development of cancer, CVD, and type 2 diabetes.

Early-onset type 2 diabetes (T2DM) may lead to very early vascular complications. Cardiovascular mortality is two to five times higher in adults with diabetes than in people without diabetes. The cardiovascular risk of young people with T2DM is unknown. T2DM in young people is associated with marked visceral obesity, insulin resistance and microalbuminuria. We recently showed that these subjects did not improve in either fitness (maximum volume of oxygen consumption, VO2max) or glucose disposal after exercise training. Seven subjects with early-onset T2DM (aged 26.1+/-0.9 years, body mass index [BMI] 35.6+/-1.2 kg/m2) and 14 age-matched obese subjects with normal glucose tolerance (aged 25.6+/-0.9 years, BMI 34.3+/-1.4 kg/m2) underwent aerobic training for 12 weeks. Serum vascular inflammatory markers (high-sensitivity C-reactive protein [hsCRP], soluble intercellular adhesion molecule [sICAM-1], soluble vascular cell adhesion molecule [sVCAM-1], E-Selectin and P-Selectin) were measured before and after the training programme. At baseline, plasma concentrations of vascular inflammatory markers were significantly elevated in both groups. They did not improve after exercise.

Silent brain infarction (SBI) is often detected on MR imaging, however the pathogenesis is still unclear. We aimed to investigate and compare the association of soluble adhesion molecules and C-reactive protein levels with the prevalence of SBI in patients with and without diabetes mellitus. We recruited 130 patients (mean age 59.6 +/- 7.6 yrs) with type 2 diabetes and 130 age- and sex-matched non-diabetic subjects. All subjects underwent head MRI to determine SBI. We measured levels of soluble intercellular adhesion molecule 1(sICAM-1), vascular cell adhesion molecule 1(sVCAM-1), and high sensitivity C-reactive protein (hs-CRP) and evaluated intima-media complex thickness (IMT) in common carotid arteries by ultrasound B-mode imaging. SBI was present in 36 (27.7%) of the diabetic patients and 31 ( 23.8%) of the non-diabetic subjects. Levels of sICAM-1, sVCAM-1 and IMT were all significantly higher in diabetic patients than in non-diabetic subjects, and were significantly increased in both subjects with SBI. IMT was only positively correlated with sVCAM-1 levels in diabetic and non-diabetic subjects. On the other hand, hs-CRP levels were not significantly different in both subjects with and without SBI. In addition, sICAM-1 levels were associated with a significantly higher relative risk for the prevalence of SBI in diabetic patients after multivariate adjustment. Our study suggests that the associations between endothelial dysfunction and presence of SBI may be stronger in diabetic patients than in nondiabetic subjects. In particular, sICAM-1 may play an important role for the pathogenesis of SBI in patients with diabetes mellitus.

We have recently found that soluble form of receptor for advanced glycation end products (sRAGE) levels are positively associated with inflammatory biomarkers and the presence of coronary artery disease (CAD) in type 2 diabetic patients. Since advanced glycation end products (AGEs) up-regulate RAGE expression and endogenous sRAGE could be generated from the cleavage of cell surface RAGE, it is conceivable that sRAGE is positively associated with circulating AGEs levels in diabetes. In this study, we examined whether sRAGE were correlated to circulating levels of AGEs and soluble forms of vascular cell adhesion molecule-1 (sVCAM-1) and intercellular adhesion molecule-1 (sICAM-1) in patients with type 2 diabetes. Eighty-two Japanese type 2 diabetic patients underwent a complete history and physical examination, determination of blood chemistries, sRAGE, AGEs, sVCAM-1 and sICAM-1. Multiple regression analysis revealed that serum levels of AGEs and sVCAM-1 were independently correlated with sRAGE. This study demonstrated that serum levels of sRAGE were positively associated with circulating AGEs and sVCAM-1 levels in type 2 diabetic patients. Our present observations suggest sRAGE level may be elevated in response to circulating AGEs, thus being a novel marker of vascular injury in patients with type 2 diabetes.
