The effect of orlistat and fenofibrate, alone or in combination, on small dense LDL and lipoprotein-associated phospholipase A2 in obese patients with metabolic syndrome.

BACKGROUND: Increased concentration of small dense LDL cholesterol (sdLDL-C) and activity of lipoprotein-associated phospholipase A2 (Lp-PLA(2)) are considered as emerging cardiovascular risk factors and are commonly encountered in subjects with metabolic syndrome (MetS). OBJECTIVE: The primary endpoint of this study was the effect of orlistat and fenofibrate, alone or in combination, on Lp-PLA(2) activity and LDL phenotype in overweight and obese patients (body mass index>28 kg/m(2)) with MetS. METHODS: Patients (n=89) were prescribed a low-fat low-calorie diet and were randomly allocated to receive orlistat 120 mg three times daily (O group), micronized fenofibrate 200mg/day (F group) or both (OF group) for 6 months. RESULTS: Significant reductions of sdLDL-C levels were observed in all treatment groups. Groups F and OF experienced a greater reduction in sdLDL-C levels (p<0.05) together with a greater increase in LDL particle diameter (p<0.05) compared with group O. Total plasma Lp-PLA(2) activity significantly decreased in all treatment groups. The reduction of Lp-PLA(2) was more pronounced with OF administration compared with each monotherapy (p<0.05). CONCLUSION: Orlistat and fenofibrate exhibited favorable effects on Lp-PLA(2) activity and LDL phenotype in overweight and obese patients with MetS. Importantly, combination treatment had a more favorable effect on these risk factors.

Statins and solid organ transplantation.

Dyslipidaemia is common in solid organ transplant recipients and its presence is associated with chronic rejection and accelerated atherosclerosis, leading to an increased prevalence of cardiovascular disease (CVD). CVD is a major cause of morbidity and mortality in transplant recipients. It is therefore of interest and clinical value to introduce agents that effectively and safely reduce the incidence of this outcome. In the present review we consider the potential benefits of statin administration in adults who have undergone solid organ (mainly renal, heart and liver) transplantation, as well as in paediatric transplant patients. We also briefly review the effects of combination therapy with ezetimibe and statins in this population. Overall, statins are efficient and safe drugs for the management of dyslipidaemias in transplant populations, and in most trials they had a beneficial effect on long-term survival rates, CVD events and rejection rates. The transplanted population is different from other patient groups, mostly due to concomitant immunosuppressive therapy. Statins, at an appropriate dosage, should be prescribed to dyslipidaemic transplanted patients but they should be closely monitored for adverse effects.
