It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia.
This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment.
After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. −0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (−55.20% vs. −7.69%, P<0.001) without previously unknown adverse drug events.
The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin’s preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

AbstractAbstract PDF
Oxidative stress is induced under diabetic conditions and causes various forms of tissue damages in the patients with diabetes. Recently, pancreatic beta cells are regarded as a putative target of oxidative stress-induced tissue damage, and this seems to explain in part the progressive deterioration of beta cell function in type 2 diabetes. The aim of this study was to examine the potential of Quercetin (QE) to protect INS-1 cells from the H2O2-induced oxidative stress and the effects of QE on the glucose-stimulated insulin secretion in INS-1 cells. METHODS: To study the cell viability, cells were incubated with H2O2 and/or QE at the various concentrations. To confirm the protective effect by QE in response to H2O2, the levels of antioxidant enzymes were assessed by RT-PCR and Western blot, and glutathione peroxidase activities were quantified by spectrophotometrical method. Glucose-stimulated insulin secretion (GSIS) was measured by ELISA. RESULTS: Cell incubations were performed with 80 microM of H2O2 for 5 hours to induce 40 - 50% of cell death. QE gradually showed protective effect (IC50 = 50 microM) in dose-dependent manner. Superoxide dismutase (SOD) mRNA level in H2O2 + QE group was increased as compared to H2O2 group, but catalase did not changed. And the QE recruited glutathione peroxidase activity against H2O2-induced oxidative injuries in INS-1 cells. CONCLUSION: In conclusion, these findings suggest that QE might have protective effect on beta cells by ameliorating oxidative stress and preserving insulin secretory function.

AbstractAbstract PDF
Insulin resistance syndrome is defined as the constellation of central obesity, hypertension, glucose abnormality and dyslipidemia. Other constituents of insulin resistance syndrome have recently been reported including serum uric acid. Causative correlation between serum uric acid and insulin resistance syndrome is still not clear. We performed epidemiologic study to clarify its correlation with insulin resistance syndrome in the people living at Kijang district of Busan City. METHODS: We performed volunteer study of the people living at Kijang district of Busan City from 16th to 19th day of November in 1998 (n=232). Height, body weight, abdominal and hip circumference, and blood pressure were measured. We also measured fasting blood glucose, fasting serum insulin (Linco RIA), HDL-cholesterol, triglyceride, total cholesterol and serum uric acid. Insulin resistance was calculated by HOMA (homeostasis model assessment) method. RESULTS: Total number of subjects were 232 (male 61, female 171), and their mean age was 5.1+/-13.4 (years), BMI (body mass index) 23.4+/-3.2 kg/m2, and WHR (waist to hip ratio) 0.82+/-0.07. Mean HOMA-IR value derived from fasting blood glucose and insulin was 2.5+/-2.4, mean serum uric acid was 270+/-72 mol/L. The serum uric acid level showed positive correlation with BMI (r=.324), WHR (r=.403), log transformed triglyceride value (r=.135), systolic blood pressure (r=.181), diastolic blood pressure (r=.185) and negative correlation with HDL-cholesterol (r=-.185,p<0.01). Stepwise linear regression revealed that only serum creatinine, WHR and natural logarithmic value of triglyceride showed statistically independent correlation with serum uric acid level. CONCLUSION: Serum uric acid level in the people living at Kijang district of Busan City showed statistically significant correlation with other well-known constituents of insulin resistance syndrome. Thus, we may conclude that the level of serum uric acid can be regarded as the component of insulin resistance syndrome in the people living at Kijang district. However, its relationship with insulin resistance syndrome may be indirect.
