Fenofibrate, a fibric acid derivative, is used to treat diabetic dyslipidemia, hypertriglyceridemia, and combined hyperlipidemia alone or in combination with statins. Rhabdomyolysis is defined as a pathological condition of skeletal muscle cell damage leading to the release of toxic intracellular material into the circulation. Its major causes include trauma, ischemia, toxins, metabolic disorders, infections, and drugs. Rhabdomyolysis associated with fenofibrate is extremely rare. In nearly all of the presented cases, there was a predisposing factor for rhabdomyolysis such as diabetes, older age, renal insufficiency, and hypothyroidism. Here, we report a nondiabetic, nonhypothyroidic young female patient without any known prior renal disease presenting with acute renal failure developing after fenofibrate treatment.

Chronic complications of type 2 diabetes, in particular, macrovascular complications, confer substantial morbidity and mortality and adversely affect a patient's quality of life. Early intensive intervention to control cardiovascular risk factors is essential in clinical management. Atherogenic dyslipidaemia characterized by elevated triglycerides, a low level of high-density lipoprotein cholesterol (HDL-C), and an increase in the preponderance of small, dense low-density lipoprotein (LDL) particles, is a key modifiable risk factor for macrovascular diabetic complications. Lowering low-density lipoprotein cholesterol (LDL-C) with a statin (or the combination of statin and ezetimibe) is the main focus for reducing cardiovascular risk in patients with diabetes. However, statins fail to address the residual cardiovascular risk associated with low HDL-C. Fibrates are effective against all components of the atherogenic dyslipidaemia associated with type 2 diabetes. Secondary analyses of the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study suggest a role for early treatment with fenofibrate in improving cardiovascular risk reduction in type 2 diabetes and provide safety data supporting the use of fenofibrate in combination with a statin. Data from the FIELD study suggest that fenofibrate may also have potential to impact on microvascular diabetic complications associated with type 2 diabetes. Data are awaited from the ongoing Action to Control Cardiovascular Risk in Diabetes (ACCORD) study to evaluate the outcome benefits of combining fenofibrate with a statin in patients with type 2 diabetes. Finally, in view of divergent study results and outstanding data, assessment of the risk of the individual with type 2 diabetes is mandatory to assist clinical decision-making when initiating lipid therapy.

Patients with type 2 diabetes or metabolic syndrome remain at high residual risk of cardiovascular events even after intensive statin therapy. While treatment guidelines recommend the addition of a fibrate to statin therapy in this setting, concerns about the potential for myopathy may limit the use of this combination in clinical practice. These concerns are certainly justified for gemfibrozil, which interferes with statin glucuronidation, leading to elevation in statin plasma concentrations and an increased risk of myotoxicity in combination with a range of commonly prescribed statins. However, the available evidence refutes suggestions that this is a class effect for fibrates. Fenofibrate does not adversely influence the metabolism or pharmacokinetics of any of the commonly prescribed statins. This in turn translates to a reduced potential for myotoxicity in combination with a statin. Data are awaited from the ongoing Action to Control Cardiovascular Risk in Diabetes (ACCORD) study to evaluate the efficacy and safety of fenofibrate plus simvastatin combination therapy in type 2 diabetes patients.

To determine whether available lipid-modifying medication can increase high-density lipoprotein (HDL) cholesterol in well-defined genetic or familial HDL-deficiency states, we studied 19 men with HDL deficiency (HDL cholesterol <5th percentile for age and gender) 55 +/- 10 years of age. Concomitant risk factors included diabetes (n = 3) and hypertension (n = 7) and 8 patients had coronary artery disease. Molecular analysis revealed that 4 patients had a mutation in the ABCA1 gene. Patients were assigned to sequentially receive atorvastatin 20 mg/day, fenofibrate 200 mg/day, and extended-release niacin 2 g/day for 8 weeks, with a 4-week washout period between each treatment. Patients in whom a statin was required, according to current treatment guidelines, were kept on atorvastatin throughout the study. Baseline HDL cholesterol level was 0.63 +/- 0.12 mmol/L (24 +/- 5 mg/dl), triglycerides 2.01 +/- 0.98 mmol/L (180 +/- 86 mg/dl), and low-density lipoprotein (LDL) cholesterol 2.29 +/- 0.95 mmol/L (94 +/- 39 mg/dl). Mean percent changes in HDL cholesterol on atorvastatin, fenofibrate, and niacin were -6% (p = NS), +6% (p = NS), and +22% (p <0.05), respectively. Furthermore, niacin significantly increased the large alpha-1 apolipoprotein A-I-containing HDL subspecies (12 to 17 nm). In conclusion, niacin was the only effective drug to increase HDL cholesterol. The absolute increase in HDL cholesterol, approximately 0.10 mmol/L (3.9 mg/dl), is of uncertain clinical significance. Biomarkers of HDL-mediated cellular cholesterol efflux were not changed by niacin therapy. Atorvastatin or fenofibrate had little effect on HDL cholesterol; atorvastatin decreased the total cholesterol/HDL cholesterol ratio by 26%. Fenofibrate did not change HDL cholesterol levels and caused an increase in LDL cholesterol. Aggressive LDL cholesterol lowering may be the strategy of choice in such patients.

Fenofibrate is a PPAR-alpha agonist indicated for the treatment of hypertriglyceridemia and mixed dyslipidemia, and is approved for the treatment of hypercholesterolemia, lipid abnormalities commonly observed in patients at high risk of cardiovascular disease, including Type 2 diabetes and/or metabolic syndromes. Treatment with fenofibrate lowers triglycerides, raises HDL-cholesterol and decreases concentrations of small LDL-cholesterol particles and apolipoprotein B. Fenofibrate is particularly effective for reducing postprandial VLDL and LDL particle concentrations, and the increased oxidative stress and inflammatory response that occurs after a fatty meal. In addition, nonlipid pleiotropic effects mediated by PPAR-alpha are likely to contribute to the reduction in atherosclerosis progression and cardiovascular events, and have beneficial effects on diabetes-related microvascular diseases. While current approaches to treating dyslipidemia to prevent cardiovascular diseases focus on statin therapy, it is increasingly clear that substantial residual risk persists. The clinical significance of combination therapy with fenofibrate and a statin to macrovascular and microvascular risk is being evaluated in a large outcomes study.

The microvascular complications of diabetes mellitus confer substantial morbidity and impair patient quality of life. Dyslipidemia and prolonged hyperglycemia promote an increase in oxidative stress, inflammation, and vascular damage, which together promote endothelial dysfunction and are associated with macrovascular and microvascular complications. Microalbuminuria is an early marker of diabetic nephropathy and an independent risk factor for cardiovascular disease. Diabetic nephropathy is the most common cause of end-stage renal disease in developed countries, and its prevalence is increasing. Preventing or limiting the progression of diabetic nephropathy, as demonstrated in the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) trial, may prevent or delay renal complications, as well as convey important cardioprotective benefits in patients with type 2 diabetes.

Clinical guidelines highlight the importance of managing atherogenic mixed dyslipidemia to reduce the risk of premature cardiovascular disease in type 2 diabetes mellitus and metabolic syndrome. The lipid-modifying activity of fenofibrate, as demonstrated in clinical studies, indicates its effectiveness in treating dyslipidemia characteristic of these conditions. Fenofibrate also has a favorable impact on a number of nonlipid residual risk factors associated with type 2 diabetes and metabolic syndrome, mediated by peroxisome proliferator-activated receptor-alpha. In patients with type 2 diabetes, fenofibrate is effective in reducing the progression of coronary artery disease, as demonstrated by the Diabetes Atherosclerosis Intervention Study (DAIS). In the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study, the primary end point (major coronary events) was not significantly reduced by fenofibrate treatment. However, other findings from this study suggest that fenofibrate reduces cardiovascular risk. Both DAIS and the FIELD study also indicate that fenofibrate may offer additional vascular benefits, specifically affecting the progression of diabetes-related microvascular disease.

The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study provides an extensive evidence base for the efficacy and tolerability of fenofibrate treatment in patients with type 2 diabetes mellitus, predominantly in a primary prevention setting. The FIELD study did not show a significant effect with fenofibrate on the primary end point, coronary artery disease death or nonfatal myocardial infarction (p = 0.16). Treatment with fenofibrate did reduce all cardiovascular disease (CVD) events, the secondary end point (by 11%, p = 0.035). The primary end point was reduced by the same percentage. The modest percent reduction in the primary and secondary end points is probably a result of a number of study confounders, notably an excess of statin drop-in therapy and disproportionate treatment with other drugs for CVD prevention in the placebo arm. Estimates of relative risk reduction used by the FIELD investigators to equalize the use of statins in the fenofibrate and placebo groups suggest a true benefit of treatment on reduction of CVD events of 17%-21%. There was no excess of elevated serum liver enzymes and no cases of rhabdomyolysis in patients receiving both fenofibrate and a statin. Prevention of microvascular disease, specifically, reduction in the rate of laser treatment for retinopathy (by 30%, p = 0.0003), progression of albuminuria (p = 0.002), and nontraumatic amputations (by 38%, p = 0.011), may well be the most innovative finding of the FIELD study, especially in view of the current lack of effective preventative treatments for diabetic retinopathy and the need for additional treatments that slow the progression of diabetic nephropathy. These findings also give impetus to investigate mechanisms by which fenofibrate and peroxisome proliferator-activated receptor-alpha activation may protect the endothelium of small blood vessels in patients with type 2 diabetes.

Even with optimal statin therapy, many patients with type 2 diabetes mellitus or metabolic syndrome fail to achieve all lipid targets and remain at high risk of cardiovascular events. Add-on lipid-modifying therapy that is effective in improving the triglyceride and high-density lipoprotein (HDL) cholesterol abnormalities characteristic of these conditions is a recommended approach to reduce this risk. Fibrates or niacin is a logical option, supported by clinical studies showing improved lipid control in combination with a statin. Of the fibrates, fenofibrate may offer microvascular benefits in type 2 diabetes--as demonstrated by the Diabetes Atherosclerosis Intervention Study (DAIS) and the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study--as well as a low risk of myopathy when combined with statins compared with gemfibrozil. Although there is good evidence that both agents favorably affect clinical outcome, we need to evaluate their impact against a baseline of statin therapy. We await data from ongoing large-scale studies to evaluate the efficacy and safety of these combinations and to determine the most appropriate option for reducing residual cardiovascular risk in this important patient population.

Diabetic eye disease confers substantial burden on the patient quality of life. Current therapeutic strategies indicate an unmet clinical need for preventive therapy. Tight control of blood pressure and glycaemia are mandatory components of primary prevention strategies, but are insufficient to eliminate risk in all patients. A body of evidence supports a role for lipid-modifying therapy in reducing the diabetic retinopathy endpoints. Although inconclusive for statin therapy, results from the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study show beneficial effects of fenofibrate in reducing the requirement for laser therapy, and particularly in preventing disease progression in patients with pre-existing diabetic retinopathy. However, there is a need for confirmation of these findings in large prospective studies with progression of retinopathy as the primary endpoint, such as the ACCORD-EYE (Action to Control Cardiovascular Risk in Diabetes-EYE) study, and in a clinical trial specifically conducted for diabetic maculopathy. In addition, elucidation of the mechanism(s) of effect of fenofibrate is indicated.
