Differences in Expression of Cardiovascular Risk Factors among Type 2 Diabetes Mellitus Patients of Different Age

Abstract

Atherosclerotic coronary heart disease and other forms of cardiovascular disease (CVD) are the major cause of mortality in type II diabetes (T2DM) as well as a major contributor to morbidity and lifetime costs. The purpose of this article is the identification of the biochemical parameters in plasma, which may serve as predisposition factors to CVD in T2DM patients of different ages. The variability of hyperglycemia, dyslipidemia, and inflammation with age progression was also studied for comparison. Four different diabetic groups allocated on the basis of the subjects' age (Group A: 15-25 years old; Group B: 26-40 years old; Group C: 40-60 years old; Group D: 60-80 years old) and consisting of 10 patients each, in parallel with 10 healthy controls matched for age, sex, and ethnic origin were screened for glucose, insulin, lipid profile (total cholesterol, triglycerides, LDL, and HDL), and inflammatory mediators (CRP, IL-6, and TNF-alpha). Significant differences were observed among the expressions of biochemical markers among different age groups. Hyperglycemia showed no variability with age whereas dyslipidemia correlated positively with age progression, as well as obesity, low physical activity, and family history of heart disease or diabetes. Marked inflammation was prominent only in Groups C and D. This article indicates that different biochemical parameters may be used for the assessment of CVD risk in T2DM patients of variable age.

Glycosylated Haemoglobin (HbA 1 c) - A Marker of Circulating Lipids in Type 2 Diabetic Patients

“…The cause of dyslipidaemia in type 2 diabetes mellitus may be due to impaired liver apolipoprotein production which in turn regulates the enzymatic activity of lipoprotein lipase and cholesterol ester transport protein [24]. Old subjects showed low levels of FBS, TC, TG and LDL [25] levels where as young type 2 diabetic patients with poor glycemic control showed significantly higher TC, TG and LDL similar to other studies [26].…”

Vanin-1 Is a Key Activator for Hepatic Gluconeogenesis

“…Obese patients suffer from chronic low-grade inflammation, as indicated by increased plasma levels of C-reactive protein, inflammatory cytokines, and multifunctional proteins, such as leptin and osteopontin (42). Inflammation is also prominent in diabetic elderly patients (43). Inflammatory mediators are known to affect liver function.…”

The Israel Diabetes and Cognitive Decline (IDCD) study: Design and baseline characteristics

“…Despite the ever-growing prevalence of both diabetes and dementia, few studies have investigated more specific determinants of risk for cognitive decline in diabetic individuals [11]. T2D is a complex metabolic disorder that is closely associated with other risk factors for dementia, such as age and hypertension [12,13]. These risk factors, together with diabetes-specific characteristics (e.g.…”
