- Diabetic nephropathy represents a condition frequently detected in current clinical practice characterized by a very high cardiovascular risk profile. Blood pressure reduction via antihypertension drug treatment represents a therapeutic approach capable of exerting favorable effects on renal and cardiovascular outcomes. The purpose of this article is to review the current literature and results of key clinical trials pertaining to blood pressure goals of antihypertension treatment in these patients. The pros and cons of a less or a more intensive blood pressure goal in diabetic nephropathy will be discussed, with particular emphasis on the cardiovascular and renal effects of each therapeutic strategy.

- Obesity is a disorder that develops from the interaction between genotype and environment involving social, behavioral, cultural, and physiological factors. Obesity increases the risk for type 2 diabetes mellitus, hypertension, cardiovascular disease, cancer, musculoskeletal disorders, chronic kidney and pulmonary disease. Although obesity is clearly associated with an increased prevalence of hypertension, many obese individuals may not develop hypertension. Protecting factors may exist and it is important to understand why obesity is not always related to hypertension. The aim of this review is to highlight the knowledge gap for the association between obesity, hypertension, and potential genetic and racial differences or environmental factors that may protect obese patients against the development of hypertension and other co-morbidities. Specific mutations in the leptin and the melaninocortin receptor genes in animal models of obesity without hypertension, the actions of α-melanocyte stimulating hormone, and SNS activity in obesity-related hypertension may promote recognition of protective and promoting factors for hypertension in obesity. Furthermore, gene-environment interactions may have the potential to modify gene expression and epigenetic mechanisms could also contribute to the heritability of obesity-induced hypertension. Finally, differences in nutrition, gut microbiota, exposure to sun light and exercise may play an important role in the presence or absence of hypertension in obesity.

- Background: Assessment of antihypertensive treatment is normally based on the mean value of a number of blood pressure (BP) measurements. However, it is uncertain whether high in-treatment visit-to-visit BP variability may be harmful in hypertensive patients with left ventricular hypertrophy (LVH).Methods: In 8505 patients randomized to losartan vs. atenolol-based treatment in the LIFE study, we tested whether BP variability assessed as SD and range for BP6-24months measured at 6, 12, 18 and 24 months of treatment was associated with target organ damage (TOD) defined by LVH on ECG and urine albumin/creatinine ratio at 24 months, and predicted the composite endpoint (CEP) of cardiovascular death, nonfatal myocardial infarction (MI) or stroke occurring after 24 months (CEP=630 events).Results: In multiple regression models adjusted for mean BP6-24months and treatment allocation, neither high BP6-24months SD nor wide range were related to TOD at 24 months, except for a weak association between Sokolow-Lyon voltage and DBP6-24months SD and range (both b=0.04, P<0.01). Independently of mean BP6-24months, treatment allocation, TOD and baseline characteristics in Cox regression models, CEP after 24 months was associated with DBP6-24months SD [hazard ratio per 1mmHg increase1.04, 95% confidence interval (95% CI) 1.01-1.06, P=0.005], range (hazard ratio 1.02, 95% CI 1.01-1.03, P=0.004), SBP6-24months SD (hazard ratio 1.01, 95% CI 0.99-1.02, P=0.07) and range (hazard ratio 1.006, 95% CI 1.001-1.01, P=0.04). Adjusted for the same factors, stroke was associated with DBP6-24months SD (hazard ratio 1.06, 95% CI 1.02-1.10, P=0.001), range (hazard ratio 1.03, 95% CI 1.01-1.04, P=0.001), SBP6-24months SD (hazard ratio 1.02, 95% CI 1.002-1.04, P=0.04) and range (hazard ratio 1.008, 95% CI 1.001-1.02, P=0.05), but MI was not.Conclusion: In LIFE patients, higher in-treatment BP6-24months variability was independently of mean BP6-24months associated with later CEP and stroke, but not with MI or TOD after 24 months.
