Serum lipids and glucose control - The SEARCH for Diabetes in Youth study
ABSTRACT To assess the relationship of serum lipid concentrations with glucose control in youth with diabetes mellitus.
Cross-sectional analyses of data from the SEARCH for Diabetes in Youth study.
Multicenter study of youth with diabetes onset at younger than 20 years. PATIENTS/ PARTICIPANTS: Nineteen hundred seventy-three SEARCH participants aged 10 years or older with hemoglobin A(1c) and fasting total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride measured at the SEARCH study examination.
There were significant trends of higher levels of TC, LDL-C, triglyceride, and non-HDL-C (but not HDL-C) with higher hemoglobin A(1c) concentrations for both diabetes types. The slopes of TC increase were 7.8 mg/dL (0.20 mmol/L) per unit increase in hemoglobin A(1c) for type 1 and 8.1 mg/dL (0.21 mmol/L) for type 2. Levels of TC, LDL-C, triglyceride, and non-HDL-C were all significantly higher (all P values <.001) in type 2 than in type 1 diabetes (mean differences in milligrams per deciliter [millimoles per liter], +13.6 [+0.35] for TC; +8.3 [+0.22] for LDL-C; +66.3 [+0.75] for triglyceride; +25.5 [+0.66] for non-HDL-C). Levels of HDL-C were lower in youth with type 2 diabetes (mean difference, -11.9 mg/dL [-0.31 mmol/L]). Among those with type 1 diabetes in poor glycemic control, 35%, 27%, and 12% had high concentrations of TC (>or=200 mg/dL [5.17 mmol/L]), LDL-C (>or=130 mg/dL [3.36 mmol/L]), and triglyceride (>or=200 mg/dL [2.26 mmol/L]), respectively. In youth with type 2 diabetes in poor glycemic control, percentages with high levels of TC, LDL-C, and triglycerides were 65%, 43%, and 40%, respectively.
Glycemic control and lipid levels are independently associated in youth with both type 1 and type 2 diabetes.

ABSTRACT: Type 2 diabetes is associated with multiple abnormalities, all of which can contribute to vascular disease. The most notable of these abnormalities include obesity, insulin resistance, hyperglycemia, dyslipidemia, hypertension, and renal disease. Although a number of these disorders are often grouped together in an entity termed "metabolic syndrome,” the increased risk for atherosclerotic disease in insulin-resistant patients correlates best with these abnormalities when each is considered individually. These abnormalities promote heart disease by inducing atherosclerosis, endothelial cell dysfunction, oxidative stress, inflammation, and vascular remodeling. This review article is focused on the prevalence of diabetes mellitus in patients with acute myocardial infarction and to determine whether cardiac markers along with routine biochemical markers measured at admission could be used to diagnose the interrelation between Myocardial infarction and diabetes mellitus.

ABSTRACT: Background: Clinicopathological correlations, as well as several angiographic studies, suggest that diabetic patients have more extensive atherosclerotic disease, affecting the coronary arteries in particular. We sought to examine the combinational effect of cardiac and biochemical markers in diabetic patients with cardiovascular disease. Method: The study population constituted 50 healthy subjects, 50 cardiovascular subjects with diabetes and 50 cardiovascular subjects without diabetes. The population was subjected to biochemical and cardiac marker analysis and the results were verified. Results and discussion: Studies suggest that glycated hemoglobin values in the abnormal range can identify persons at increased risk for coronary heart disease, stroke, and death before the diagnosis of diabetes, indicating that glycated hemoglobin is a useful marker of cardiovascular risk and death from any cause.

ABSTRACT: The changes in glycated hemoglobin levels in the two study groups varied markedly according to age group (P = 0.003), with a significant difference among patients 25 years of age or older that favored the continuous-monitoring group (mean differ- ence in change, −0.53%; 95% confidence interval (CI), −0.71 to −0.35; P
