The effects of lipid-lowering drug therapy on cardiovascular responsiveness in type 2 diabetic patients

Statin Therapy Before Transition to End-Stage Renal Disease With Posttransition Outcomes

Background Although studies have shown that statin therapy in patients with non-dialysis-dependent chronic kidney disease was associated with a lower risk of death, this was not observed in dialysis patients newly initiated on statins. It is unclear if statin therapy benefits administered during the predialysis period persist after transitioning to end-stage renal disease. Methods and Results In 47 720 veterans who transitioned to end-stage renal disease during 2007 to 2014, we examined the association of statin therapy use 1 year before transition with posttransition all-cause and cardiovascular mortality and hospitalization incidence rates over the first 12 months of follow-up. Associations were examined using multivariable adjusted Cox proportional hazard models and negative binomial regressions. Sensitivity analyses included propensity score and subgroup analyses. The cohort's mean± SD age was 71±11 years, and the cohort included 4% women, 23% blacks, and 66% diabetics. Over 12 months of follow-up, there were 13 411 deaths, with an incidence rate of 35.3 (95% CI , 34.7-35.8) deaths per 100 person-years. In adjusted models, statin therapy compared with no statin therapy was associated with lower risks of 12-month all-cause (hazard ratio [95% CI], 0.79 [0.76-0.82]) and cardiovascular (hazard ratio [95% CI ], 0.83 [0.78-0.88]) mortality, as well as with a lower rate of hospitalizations (incidence rate ratio [95% CI ], 0.89 [0.87-0.92]) after initiating dialysis. These lower outcome risks persisted across strata of clinical characteristics, and in propensity score analyses. Conclusions Among veterans with non-dialysis-dependent chronic kidney disease, treatment with statin therapy within the 1 year before transitioning to end-stage renal disease is associated with favorable early end-stage renal disease outcomes.

State of the Art Reviews: Relationship Between Diet/ Physical Activity and Health

Obesity and 4 of the leading causes of death—heart disease, cancer, stroke, and type 2 diabetes mellitus—are related to lifestyle. The combination of a healthy weight, prudent diet, and daily physical activity clearly plays a role in primary, secondary, and tertiary prevention of these and other chronic diseases. Because nearly 65% of the adult population is overweight or obese, weight loss and maintenance are central to this review article. Improved lipid profiles, blood pressure, insulin sensitivity, and euglycemia are associated with weight loss or a normal body weight; thus, maintaining a healthy weight is a universal recommendation for health. The methods for improving lifestyle described in the section on obesity include assessing nutritional status and stages of change of the client, setting realistic goals, eating a diet high in fruits and vegetables with low-fat sources of dairy and protein, and achieving appropriate physical activity levels. The importance of physicians discussing weight with clients and vice versa is stressed. The common features of lifestyle-related diseases make them amenable to similar lifestyle interventions.

The effects of pitavastatin, eicosapentaenoic acid and combined therapy on platelet-derived microparticles and adiponectin in hyperlipidemic, diabetic patients

Platelet-derived microparticles (PDMP) play an important role in the pathogenesis of diabetic vasculopathy, and statins or eicosapentaenoic acid (EPA) have been shown to have a beneficial effect on atherosclerosis in hyperlipidemic patients. However, the influence of EPA and statins on PDMP and adiponectin in atherosclerosis is poorly understood. We investigated the effect of pitavastatin and EPA on circulating levels of PDMP and adiponectin in hyperlipidemic patients with type II diabetes. A total of 191 hyperlipidemic patients with type II diabetes were divided into three groups: group A received pitavastatin 2 mg once daily (n = 64), group B received EPA 1800 mg daily (n = 55) and group C received both drugs (n = 72). PDMP and adiponectin were measured by ELISA at baseline and after 3 and 6 months of drug treatment. Thirty normolipidemic patients were recruited as healthy controls. PDMP levels prior to treatment in hyperlipidemic patients with diabetes were higher than levels in healthy controls (10.4 +/- 1.9 vs. 3.1 +/- 0.4 U/ml, p < 0.0001), and adiponectin levels were lower than controls (3.20 +/- 0.49 vs. 5.98 +/- 0.42 microg/ml, p < 0.0001). PDMP decreased significantly in group B (before vs. 6M, 10.6 +/- 2.0 vs. 8.0 +/- 1.7 U/ml, p < 0.01), but not in group A (before vs. 6M, 9.4 +/- 1.9 vs. 9.6 +/- 1.7 U/ml, not significant). In contrast, group A exhibited a significant increase in adiponectin levels after treatment (before vs. 6M, 3.29 +/- 0.51 vs. 4.16 +/- 0.60 microg/ml, p < 0.001). Furthermore, group C exhibited significant improvement in both PDMP and adiponectin levels after treatment (PDMP, before vs. 6M, 11.2 +/- 2.0 vs. 4.5 +/- 2.7 U/ml, p < 0.001; adiponectin, before vs. 6M, 3.24 +/- 0.41 vs. 4.02 +/- 0.70 microg/ml, p < 0.001). Reductions of PDMP in combined therapy were significantly greater than those observed with EPA alone (p < 0.05 by ANOVA). In addition, soluble CD40 ligand exhibited almost the same change as PDMP in all therapy groups. These results suggest that pitavastatin possesses an adiponectin-dependent antiatherosclerotic effect, and this drug is able to enhance the anti-platelet effect of EPA. The combination therapy of pitavastatin and EPA may be beneficial for the prevention of vascular complication in hyperlipidemic patients with type II diabetes.
