Could antioxidant supplementation delay progression of cardiovascular disease in end-stage renal disease patients?

Could antioxidant supplementation delay progression of cardiovascular disease in end-stage renal disease patients? Curr Vasc Pharmacol. 2020 Mar 17;: Authors: Roumeliotis S, Roumeliotis A, Gorny X, Mertens P Abstract In end-stage renal disease patients the leading causes of mortality are of cardiovascular origin. The underlying mechanisms are complex, given that sudden heart failure is more common than acute myocardial infarction. Notwithstanding, a contributing role of oxidative stress is postulated, which is increased even at early stages of chronic kidney disease, is gradually augmented in parallel to its progression to end-stage renal disease and is further accelerated by renal replacement therapies. Oxidative stress ensues when there is an imbalance between reactive pro-oxidants and physiologically occurring, electron donating antioxidant defense systems. Renal replacement therapies such as hemodialysis and peritoneal dialysis, aggravate oxidative stress by the procedures per se. A close association of oxidative stress with accelerated atherosclerosis and increased risk for cardiovascular and all-cause mortality has been described. Especially lipid peroxidation has been identified which triggers endothelial dysfunction as a first step in atherogenesis. To counteract the deleterious effects of free radicals and thereby ameliorate or retard cardiovascular disease exogenous administration of antioxidants has been proposed. Here, we attempt to summarize...

In conclusion, the concept of an epigenetic clock is compelling, but caution should be taken in interpreting associations with age acceleration. Association tests of age acceleration should include age as a covariate.

Conclusion A great deal of progress is being made in the matter of treating aging: in advocacy, in funding, in the research and development. It can never be enough, and it can never be fast enough, given the enormous cost in suffering and lost lives. The longevity industry is really only just getting started in the grand scheme of things: it looks vast to those of us who followed the slow, halting progress in aging research that was the state of things a decade or two ago. But it is still tiny compared to the rest of the medical industry, and it remains the case that there is a great deal of work yet to be done at all...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

By WILLIAM H. BESTERMANN JR., MD New Scientific Breakthroughs Can Provide a Longer Healthier Life Twenty-one years of follow-up comparing usual care with a protocol-driven team-based intervention in diabetes proved that healthy life in humans can be prolonged by 8 years. These results were achieved at a lower per patient per year cost. Aging researchers have been confident that we will soon be able to prolong healthy life. This landmark study shows this ambitious goal can be achieved now with lifestyle intervention and a few highly effective proven medications. These medications interfere with the core molecular biol...

Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

In conclusion, in the Framingham Heart Study population, in the last 30 years, disease duration in persons with dementia has decreased. However, age-adjusted mortality risk has slightly decreased after 1977-1983. Consequences of such trends on dementia prevalence should be investigated.
