Soluble epoxide hydrolase inhibition protects the kidney from hypertension-induced damage.
Epoxyeicosatrienoic acids (EET) have antihypertensive and anti-inflammatory properties and play a role in the maintenance of renal vascular function. A novel approach to increase EET levels is to inhibit epoxide hydrolase enzymes that are responsible for conversion of biologically active EET to dihydroxyeicosatrienoic acids (DHET). We hypothesized that soluble epoxide hydrolase (SEH) inhibition would improve renal vascular function and ameliorate hypertension induced renal damage. ⋯ Protection of the renal vasculature and glomerulus during chronic CDU administration was demonstrated by histology. Urinary albumin excretion, an index of renal damage, was also lower in CDU-treated hypertensive rats. These data demonstrate that SEH inhibition has antihypertensive and renal vascular protective effects in angiotensin hypertension and suggests that SEH inhibitors may be a useful therapeutic intervention for cardiovascular diseases.

Meta AnalysisChronic kidney disease as a risk factor for cardiovascular disease and all-cause mortality: a pooled analysis of community-based studies.
Chronic kidney disease (CKD) is a major public health problem. Conflicting evidence exists among community-based studies as to whether CKD is an independent risk factor for adverse cardiovascular outcomes. After subjects with a baseline history of cardiovascular disease were excluded, data from four publicly available, community-based longitudinal studies were pooled: Atherosclerosis Risk in Communities Study, Cardiovascular Health Study, Framingham Heart Study, and Framingham Offspring Study. ⋯ Black individuals with CKD had an adjusted HR of 1.76 (95% CI, 1.35-2.31), whereas whites had an adjusted HR of 1.13 (95% CI, 1.02-1.26). CKD is a risk factor for the composite outcome of all-cause mortality and cardiovascular disease in the general population and a more pronounced risk factor in blacks than in whites. It is hypothesized that this effect may be due to more frequent or more severe subclinical vascular disease secondary to hypertension or diabetes in black individuals.
