Serum nitric oxide levels correlate with quality of life questionnaires scores of hypothyroid females.

Primary hypothyroidism can affect lipid metabolism, cardiovascular (CV) function, and overall patients' quality of life (QoL). Decrease in serum nitric oxide (NO) levels could promote the atherosclerosis acceleration in hypothyroid patients. Our hypothesis is that serum NO level is altered in hypothyroidism; more specifically, we hypothesize that the early vascular changes that can be observed in hypothyroidism could be due to these alterations and that serum NO levels are associated with lipid levels in female patients diagnosed with subclinical hypothyroidism (SCH) or clinical hypothyroidism (CH).

The hypertriglyceridemic waist phenotype and metabolic syndrome by differing criteria in type 2 diabetic patients and their relation to lipids and blood glucose control.

Background: Metabolic syndrome (MetS) describes clustering of obesity, dyslipidemia, hyperglycemia and hypertension and increases risk for cardiovascular disease and type 2 diabetes. The 'hypertriglyceridemic waist' phenotype (HTGW) represents a simple approach to identifying individuals with increased risk. The aim of the study was to determine the prevalence of HTGW and MetS in type 2 diabetic patients, and to examine their relation to lipids and blood glucose control.
