METHODS Participants with type 1(n = 23) and type 2 diabetes(n = 127) had mean and mean maximum CCA IMT measured using B mode ultrasound. Dietary intake was measured using a food frequency questionnaire. Clinical and dietary predictors of mean and mean maximum CCA IMT were determined using linear regression analysis adjusted for potential confounders. RESULTS The main predictors of mean and mean maximum CCA IMT were age and weight. After multivariate adjustment there were no dietary predictors of CCA IMT. However,in subjects that were not prescribed a lipid lowering medication alcohol consumption was positively associated with CCA IMT after multivariate adjustment. No difference existed in CCA IMT between subjects with type 1 or type 2 diabetes once age was adjusted for. CONCLUSION CCA IMT was predominantly predicted by age and weight in these subjects with diabetes. The finding that CCA IMT was not different between people with type 1 and type 2 diabetes warrants further investigation in a larger cohort.展开更多

Subjects: A case-control study on 90 participants aged 60 years and older divided into 60 cases (30 patients with DM alone and 30 patients with DM and comorbidities) and 30 healthy controls. All were assessed by measuring CIMT, ankle brachial index (AB), and markers for cardiovascular disease such as high-sensitivity CRP (hs-CRP), total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), and low density lipoprotein (LDL). Results: hs-CRP levels showed statistically significant difference being highest among patients with DM and comorbidities and lowest among controls (P < 0.001). Also, symptoms of PAD were significantly higher among cases than controls. ABI was able to detect PAD in many asymptomatic patients. Color changes were present in only 43.30% (n = 26) of positive PAD cases while delayed wound healing, claudication pain, rest pain, cold extremities, and trophic changes were present in 23.30% (n = 14), 16.71% (n = 10), 16.71% (n = 10), 45.00% (n = 27), and 21.7% (n = 13). Using logistic regression analysis revealed that DM, CIMT, and hs-CRP were independent predictors for PAD (OR = 4.194, 7.236, 1.003;P value = 0.044, 0.25, 0.031) after adjustment of other coronary risk factors such as sex, smoking, hypertension, TC, and TG. Conclusion: Diabetic elderly have higher prevalence of asymptomatic PAD thannon-diabetics using solely ABI. DM, CIMT, and hs-CRP are independent predictors for the occurrence of PAD. Hs-CRP levels are highest among diabetics with comorbidities.展开更多

Methods A total of 3,237 participants aged ≥ 40 years were recruited from Jidong community in 2013-2014. Participants were divided into five quintile groups based on their serum ALP levels. Carotid atherosclerosis was assessed using ultrasound. Abnormal IMT, carotid plaque, and ECAS were defined as IMT > 0.9 mm, IMT > 1.5 mm, and ≥ 50% stenosis in at least one extracranial carotid artery, respectively. Results Common carotid IMT values and the prevalence of carotid plaque increased across serum ALP quintiles. Higher ALP quintiles were correlated with an increased risk of abnormal IMT [fourth quintile: odds ratio(OR) 1.78, 95% confidence interval(CI) 1.13-2.82, P = 0.0135;fifth quintile: OR = 1.82, 95% CI: 1.15-2.87, P = 0.0110] and ECAS compared to the lowest quintile(fifth quintile: OR = 1.47, 95% CI: 1.09-1.97, P = 0.0106). The association between ALP and prevalence of carotid plaque became insignificant after adjustment for confounders. Conclusion Serum ALP levels were independently associated with abnormal common carotid IMT and ECAS. These conclusions need to be further corroborated in future prospective cohort studies.展开更多

Methods: Two-hundred and ten patients with new-onset type 2 diabetes mellitus were randomly assigned to two groups: an intensive treatment group (n=110) and a conventional treatment group (n=100). Fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c), blood pressure, blood lipids [total cholesterol (TC), triglyceride (TG), low-density lipoprotein C (LDL-C), and high-density lipoprotein C (HDL-C)], and IMTs of large arteries (carotid, iliac, and femoral arteries) were determined before and at one and two years after starting treatment. The patients in the conventional treatment group received routine diabetes management in our outpatient department. Targets were established for patients in the intensive treatment group. Their blood glucose, blood lipids, and blood pressure levels were regularly monitored and therapeutic regimens were adjusted for those whose measurements did not meet the target values until all the parameters met the established targets. Within-group and between-group differences were evaluated. Results: A significantly greater percentage of patients in the intensive treatment group had LDL-C levels that reached the target value one year after starting treatment than those in the conventional treatment group (52.04% vs. 33.33%, P<0.05). No significant differences were found be- tween groups for FBG, HbA1c, blood pressure, TG, TC, or HDL-C. The percentages of patients with TG (51.02% vs. 34.48%), TC (52.04% vs. 33.33%), and LDL-C (61.22% vs. 43.67%) who met the respective target values in the in- tensive treatment group were all significantly higher than the corresponding percentages in the conventional treatment group two years after starting treatment (P<0.05). There were no significant differences in the percentages of patients with FBG, HbA1c, and blood pressure values meeting the respective targets between the groups at the two-year follow- up. One year after starting treatment, the LDL-C level, diastolic blood pressure (DBP), and the IMTs of the femoral and iliac arteries of the intensive treatment group were significantly lower compared to those of the conventional treatment group (P<0.05), although there was no significant difference in other metabolic parameters. Two years after starting treatment, the TC, LDL-C, blood pressure [systolic blood pressure (SBP) and DBP], and the IMTs of the carotid and femoral arteries of the intensive treatment group were significantly lower than those of the conventional treatment group (P<0.05). No significant differences in other metabolic parameters existed between the two groups two years after starting treatment. Conclusions: Early comprehensive and intensive treatment of type 2 diabetes mellitus can delay or even reverse the increase in IMT of large arteries. Lowering blood pressure and blood lipid regulation in patients with type 2 diabetes mellitus have great significance in decreasing the risk of diabetes-related macrovascular lesions.展开更多
