Kidney complications: Why don't statins always work?

Abstract

The vasculature suffers damage as a result of diabetes, often leading to conditions such as kidney failure. In bench to bedside, Christian Rask-Madsen and George King examine endogenous factors that protect against damage of the vasculature, such as vascular-endothelial growth factor (VEGF). Recent studies report that VEGF is expressed by kidneys and fends off renal failure; such findings have implications for the development of treatments that harness endogenous factors and sound a note of caution for the therapeutic use of VEGF inhibitors. People with end-stage renal disease often die of cardiovascular complications and clinical studies have shown that one popular class of drugs, statins, does not work in this population. In bedside to bench, S. Ananth Karumanchi and Ravi Thadhani show how this clinical finding is spurring research into the biological mechanisms behind cardiovascular death in people with kidney disease.
