The present study comprised 100 patients of essential hypertension who were screened for fasting hyperinsulinemia, which was detected in 77% cases. Twenty such hyperinsulinemic cases were subjected to 4 weeks of dietary control phase followed by 6 weeks of omega-3 fatty acids substitution [either 0.6 g/d (group 1) or 1.2 g/d (group 2)]. The mean basal fasting plasma insulin levels were significantly higher (p<0.001) in patients of hypertension when compared to normal controls (126.51±80.36 and 19.35±12.61 μU/ml respectively). At the end of 4 weeks of diet control only, no significant change was observed in any parameter. After substitution of omega-3 fatty acid, a significant reduction of fasting plasma insulin levels in both group 1 (29%) and group 2 (22.8%) was observed (p<0.001). Significant reduction of systolic and diastolic blood pressure (16.4% and 25% respectively), serum cholesterol, triglycerides and low density lipoprotein was also noted in both groups (p<0.001), while high density lipoprotein increased by ∼8 mg% in both groups. Thus omega-3 fatty acid substituion in low dose along-with curtailment of dietary omega-6 fatty acid may be used as an adjunctive measure in the management of essential hypertension.  相似文献   

Hyperinsulinemia and Hypoadiponectinemia are Associated with Increased Risk for Occurrence of Ovarian Cancer in Non-diabetic Women of North Indian Population

Ovarian cancer has been emerged as a most common and lethal gynecological malignancy in India. High serum insulin and low adiponectin have been associated with increased risk of ovarian cancer. But their role in development of ovarian cancer is conflicting and little evidence is available. We aimed to evaluate blood levels of insulin and adiponectin in epithelial ovarian cancer (EOC) patients and their association with the risk to develop EOC. The study included following three groups; Group 1: fifty cases of cytohistopathologically confirmed cases of EOC, Group 2: fifty age matched cases of benign ovarian conditions and Group 3: fifty ages matched healthy controls with no evidence of any benign or malignant ovarian pathology as ruled out by clinical examination and relevant investigations. Cytohistopathologically confirmed and newly diagnosed cases of EOC and benign ovarian cancer were included in this study. The median value of fasting serum insulin was significantly high (15.0 µlU/ml, P = 0.02) and adiponectin were significantly low (5.1 µg/ml, P < 0.001) in ovarian cancer patients compared to benign ovarian tumors and healthy controls group. A significant increase risk of ovarian cancer was found in high tertile (≥ 18.7 µlU/ml) of serum insulin level (OR = 2.7; 95% CI = 1.00–6.67, P = 0.04) and lower tertile (≤ 5.45 µg/ml) of adiponectin level (OR = 3.2; 95% CI = 1.10–9.71, P = 0.03). High serum insulin level and low adiponectin levels were significantly associated with increased risk for development of ovarian cancer.  相似文献   

Hyperinsulinemia predisposes to NAFLD

Metabolic syndrome contributes to pathogenesis of Type-2 diabetes and CAD. Insulin Resistance is the key factor of metabolic syndrome implicated in development of Non Alcoholic Fatty Liver Disease (NAFLD). In present study we have investigated the prevalence of NAFLD in metabolic syndrome and contribution of metabolic risk factors in causation of NAFLD in non-diabetic North Indian male population. The study was conducted on 495 non-diabetic, nonalcoholic subjects (age 30–65 years). Metabolic Syndrome was assessed by using ATP III and ADA (2005) criteria. Anthropometric factors-Waist circumference and blood pressure were measured. Fasting serum samples were analyzed for Glucose, Triglycerides, Cholesterol and its fractions, Insulin, Alanine transaminase, Aspartate transaminase, Gamma glutamyl transferase and free fatty acids. Insulin resistance was estimated by Homeostasis Model and Insulin sensitivity by QUICKI Index. Liver ultrasonographic scanning was used for assessing fatty liver. The prevalence of metabolic syndrome and NAFLD was 24% and 14.8% respectively in non-alcoholic population and 27% of metabolic syndrome had NAFLD which was associated with hyperinsulinemia, insulin resistance, insulin insensitivity along with elevated levels of waist circumference, blood pressure, triglyceride, FFA and decreased HDL-Cholesterol. The prevalence of NAFLD increased with insulin resistance and clustering of metabolic risk factors.  相似文献
