Relationships between Cardiac Autonomic Neuropathy and the Brachial-ankle Pulse Wave Velocity in Patients with Type 2 Diabetes

BACKGROUND: Cardiovascular disease is the leading cause of death in patients with type 2 diabetes. Clinically, evaluating cardiovascular autonomic neuropathy (CAN) is important to predict cardiovascular mortality because it is correlated with cardiovascular death. The pulse wave velocity (PWV) correlates well with arterial distensibility and stiffness. It is also a useful approach for evaluating the severity of systemic atherosclerosis in adults. So, we evaluated that the relationship between cardiac autonomic neuropathy and the brachial-ankle pulse wave velocity (baPWV) in patients with type 2 diabetes. METHODS: We retrospectively analyzed 465 patients (209 men and 256 women) with type 2 diabetes. We checked the clinical characteristics and the laboratory tests and we assessed the diabetic complications. Standard tests for CAN were performed by DiCAN (Medicore, Seoul, Korea): 1) heart rate variability during deep breathing (the E/I ratio), 2) a Valsalva maneuver, 3) 30:15 ratio of R-R interval the blood pressure response to standing, and 5) the blood pressure response to handgrip. The CAN score was determined according to the results of the test as following: 0 = normal, 0.5 = borderline, 1 = abnormal. We also measured the baPWV by using a VP 1000 (Colin, Japan) and all the analyses were performed with the SPSS version 14.0. P values < 0.05 were considered significant. RESULTS: The CAN score is associated with the maximal baPWV, age, systolic blood pressure, microalbuminuria, the duration of diabetes, angiotensin II receptor blocker treatment, calcium channel blocker treatment, beta-blocker treatment and nephropathy. After adjusting for age, the baPWV is a independent predictor of the risk for CAN (beta = 0.108, P = 0.021). CONCLUSION: The CAN is associated with the baPWV in patient with type 2 diabetes.

The Association between Type 2 Diabetes Mellitus and Colorectal Cancer

BACKGROUND: There is a close connection between type 2 diabetes mellitus and the risk of cancers and related mortality. The principal objective of the present study was to explore the association between type 2 diabetes and colorectal cancer. METHODS: We retrospectively compared 1111 subjects (age > or = 30 years) who were subjected to colonoscopies between June 2006 and June 2009. We evaluated the anthropometric data, presenting symptoms and signs, history of diabetes, laboratory data, colonoscopy findings and biopsy results. We analyzed the correlation between colorectal cancer and influencing factors, and compared the incidence rates of colorectal cancer in the type 2 diabetes and control groups. RESULTS: Four hundreds and seven of the subjects had diabetes mellitus. The incidence of colorectal cancer was increased significantly in type 2 diabetes relative to the control group (7.4% vs. 3.4%, P < 0.05). Colorectal cancer was correlated significantly with age, type 2 diabetes, constipation, anemia, and gastrointestinal symptoms. Following logistic regression analysis, age and constipation were associated significantly with colorectal cancer. In the age below 65 years subgroup, the incidence of colorectal cancer was increased significantly in the type 2 diabetes group relative to the control group. CONCLUSION: Type 2 diabetes was associated with increased colorectal cancer risk. This association was more definite in the subjects younger than 65 years.

Determinants of 1-Year Changes of Brachial Ankle Pulse Wave Velocity (baPWV) in Patients with Type 2 Diabetes Mellitus / 당뇨병

BACKGROUND: Cardiovascular disease is the leading cause of mortality in type 2 diabetes. PWV correlates well with arterial distensibility and stiffness and a useful approach for evaluating the severity of systemic atherosclerosis in adults, and, in particular, the measurement of brachial-ankle PWV (baPWV) has been commonly reported as a simple, noninvasive and practicable method. baPWV was mainly affected by age, SBP and sex. And also, baPWV was affected by many different factors such as body weight, BMI, waist to hip ratio, HbA1c, microalbuminuria, triglyceride, gammaGTP, duration of DM. We evaluated determinants of 1-year changes of baPWV in patients with type 2 DM. METHODS: The study group comprised 189 diabetic patients who measured ankle brachial pressure index (ABI), baPWV at base line and 1-year later. The anthropometric parameters, blood pressure, pulse pressure, fasting plasma glucose (FBS), fasting insulin, A1c, lipid profile, hsCRP, microalbuminuria, AST/ALT, gammaGTP were also checked concurrently. We also analyzed correlation between change of baPWV and subject's medications. We retrospectively analyzed the relationship between the 1-year changes of baPWV and the other factors. All analyses were performed with the SPSS Version 14.0 and P values < 0.05 were considered significant. RESULTS: baPWV change was affected by systolic blood pressure change, diastolic blood pressure change, pulse pressure change, body weight, BMI, triglyceride change, insulin treatment and total cholesterol. Multiple regression analysis of the relationship between change of baPWV and other associated variables shows that the 1-year change of baPWV was significantly associated with the changes of blood pressure and insulin treatment in patients with type 2 DM. CONCLUSION: 1-year change of baPWV was significantly associated with the changes of blood pressure in patients with type 2 DM.
