Neovascular eye diseases including retinopathy of prematurity, diabetic retinopathy and age-related-macular-degeneration are major causes of blindness. Fenofibrate treatment in type 2 diabetes patients reduces progression of diabetic retinopathy independent of its peroxisome proliferator-activated receptor (PPAR)α agonist lipid lowering effect. The mechanism is unknown. Fenofibrate binds to and inhibits cytochrome P450 epoxygenase (CYP)2C with higher affinity than to PPARα. CYP2C metabolizes ω-3 long-chain polyunsaturated fatty acids (LCPUFAs)...

Insulin resistance (IR) is an important determinant of type-2 diabetes mellitus (T2DM). Free fatty acids (FFAs) induce IR by various mechanisms. A surfeit of circulating FFA leads to intra-myocellular lipid accumulation that induces mitochondrial ROS generation and worsens IR. However, the molecular mechanisms behind are unclear. We identified thioredoxin interacting protein (TxNIP), which is overexpressed in T2DM, to be a promoter of ROS-induced IR. We observed upregulation of TxNIP upon palmitate treatment in skeletal muscle cells that led to ROS generation and Glut-4 downregulation resulting in impaired glucose-uptake...

Diabetic retinopathy (DR) is the most frequent microvascular complication from diabetes and requires annual screening and at least annual follow-up. A systemic approach to optimize blood glucose and blood pressure may halt progression to severe stages of DR and obviate the need for ocular treatment. Although there is evidence of benefit from fenofibrate or intravitreous antiVEGF treatment for eyes with nonproliferative DR (NPDR), these therapies are not standard care for NPDR at this time. Some patients with severe NPDR, especially those with type 2 diabetes, benefit from early panretinal photocoagulation (PRP)...

High-fat diet reduces the expression of the carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), a transmembrane glycoprotein that promotes insulin clearance and downregulates fatty acid synthase activity in the liver upon its phosphorylation by the insulin receptor. Because peroxisome proliferator-activated receptoralpha (PPARalpha) transcriptionally suppresses CEACAM1 expression, we herein examined whether high-fat downregulates CEACAM1 expression in a PPARalpha;-dependent mechanism. By activating PPARalpha, the lipid-lowering drug fenofibrate reverses dyslipidemia and improves insulin sensitivity in type 2 diabetes in part by promoting fatty acid oxidation...

UNLABELLED: Dyslipidemia in type 2 diabetics represents a complex change of lipoprotein metabolism that is highly proatherogenic. It originates on a genetic background in the context of insulin resistance and affects lipoprotein metabolism at multiple levels (e.g. hepatocyte, enterocyte, intravascular processing) mainly in the postprandial phase. The treatment of diabetic (atherogenic) dyslipidemia is an effective option to lower the risk of both macro- and microvascular complications of diabetes...

To control lipid factors risk, beyond proper management of LDL cholesterol according to individual risk, detection and treatment of atherogenic dyslipidemia and abnormal levels of triglycerides or HDL cholesterol it should be considered for address a global cardiovascular protection, both in primary and secondary prevention. In this sense, these recommendations collect data on efficacy and safety about the combination statin with fibrates, often necessary for total control of dyslipidemia, particularly in patients with metabolic disorders such as diabetes mellitus, metabolic syndrome or visceral obesity...

Diabetic nephropathy (DN), a chronic complication of diabetes, is charecterized by glomerular hypertrophy, proteinuria, decreased glomerular filtration, and renal fibrosis resulting in the loss of renal function. Although the exact cause of DN remains unclear, several mechanisms have been postulated, such as hyperglycemia-induced renal hyper filtration and renal injury, AGEs-induced increased oxidative stress, activated PKC-induced increased production of cytokines, chemokines, and different inflammatory and apoptotic signals...

Fenofibrate is a synthetic ligand for peroxisome proliferator-activated receptors subtype alpha (PPARa); it is used for the treatment of a wide range of metabolic diseases such as hypertriglyceridemia, dyslipidemia, diabetes and various neurodegenerative diseases. We have studied the effect of fenofibrate on b-oxidation of fatty acids and related free-radical processes. The most effective concentration of fenofibrate (0.3%) added to the chow caused a significant decrease of the body weight of mice. The data obtained by quantitative PCR demonstrated increased hepatic gene expression responsible for b-oxidation of fatty acids in peroxisomes and mitochondria...

Peroxisome proliferator-activated receptor-α (PPARα) displays renoprotective effects with an unclear mechanism. Aberrant activation of the canonical Wnt pathway plays a key role in renal fibrosis. Renal levels of PPARα were down-regulated in both type 1 and type 2 diabetic models. The PPARα agonist fenofibrate and over-expression of PPARα both attenuated expression of fibrotic factors and suppressed high glucose- or Wnt3a-induced Wnt signaling in renal cells. Fenofibrate inhibited Wnt signaling in the kidney of diabetic rats...

Diabetic retinopathy, a common and sight-threatening microvascular complication of diabetes mellitus, is a leading cause of blindness among working-aged adults. Medical therapies including intensive control of hyperglycemia and hypertension have been shown to reduce the incidence and progression of diabetic retinopathy. The association of dyslipidemia and treatment with statins with diabetic retinopathy is inconsistent in epidemiologic studies. However, two recent randomized clinical trials have demonstrated beneficial effects of systemic fenofibrate therapy in reducing the progression of diabetic retinopathy independently of serum lipid levels...

Vision loss affects 37 million Americans older than 50 years and one in four who are older than 80 years. The U.S. Preventive Services Task Force concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for impaired visual acuity in adults older than 65 years. However, family physicians play a critical role in identifying persons who are at risk of vision loss, counseling patients, and referring patients for disease-specific treatment. The conditions that cause most cases of vision loss in older patients are age-related macular degeneration, glaucoma, ocular complications of diabetes mellitus, and age-related cataracts...

Diabetes causes a panretinal neurodegeneration herein termed diabetic retinal neuropathy, which manifests in the retina early and progresses throughout the disease. Clinical manifestations include changes in the ERG, perimetry, dark adaptation, contrast sensitivity and colour vision which correlate with laboratory findings of thinning of the retinal neuronal layers, increased apoptosis in neurons and activation of glial cells. Possible mechanisms include oxidative stress, neuronal AGE accumulation, altered balance of neurotrophic factors, and loss of mitohormesis...

The incidence and the public health importance of diabetes mellitus are growing continuously. Despite the improvement observed in recent years, the leading cause of morbidity and mortality of diabetics are cardiovascular diseases. The diagnosis of diabetes mellitus constitutes such a high risk as the known presence of vascular disease. Diabetic dyslipidaemia is characterised by high fasting and postprandial triglyceride levels, low HDL level, and slightly elevated LDL-cholesterol with domination of atherogenic small dense LDL...

We examined the effects of fish oil and fenofibrate (FF) on the pancreatic islet hypertrophy, and on the modification of glucose and lipid metabolic dysfunctions in KK mice with insulin resistance. The mice were fed one of four diets [25en% lard/safflower oil (LSO), 25en% fish oil (FO), or each of these diets plus 0.1wt% FF (LSO/FF, FO/FF)] for 9 weeks. FO group and both FF groups had significantly lower final body and adipose tissue weights than LSO group. Pancreatic islet hypertrophy was observed only in LSO group but not in the other groups with fish oil or FF...

AIMS: Reported associations between liver enzymes and mortality may not hold true in type 2 diabetes, owing to a high prevalence of non-alcoholic fatty liver disease, which has been linked to cardiovascular disease and mortality in its own right. Our study aimed to determine whether alanine aminotransferase (ALT) or γ-glutamyl transferase (GGT) levels predict mortality in type 2 diabetes, and to examine possible mechanisms. METHODS: Data from the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study were analyzed to examine the relationship between liver enzymes and all-cause and cause-specific mortality over 5years...
