Abstract
OBJECTIVE Dyslipidaemia and central obesity are the major factors underlying the dramatic increase in metabolic syndrome (MS). We compared the effects of early combined therapy with pitavastatin and intensive lifestyle modification (LSM) on the amelioration of each component of MS with those of LSM only. DESIGN/PARTICIPANTS/MEASUREMENTS PROPIT (a PROspective comparative clinical study to evaluate the efficacy and safety of PITavastatin in patients with metabolic syndrome) was a prospective, randomized, multicenter open-label 48-week trial. We enrolled 187 patients with MS (central obesity and prediabetes) and randomized them into two treatment groups: 2 mg pitavastatin daily + intensive LSM or intensive LSM only. The primary outcome was the improvements in the components of MS and in the percentage of non-MS converters. RESULTS After 1 year treatment, the improvement of MS score was significantly higher in the pitavastatin + LSM group (P = 0·039). However, non-MS converters (MS score ≤2) did not differ between the groups. The secondary outcomes, namely lipid profiles, the Apo B/A1 ratio, visceral fat/subcutaneous fat ratio and the Framingham risk score, were significantly improved in the pitavastatin group. There was no deterioration in glucose metabolism after treatment with pitavastatin for 1 year. CONCLUSIONS Early statin treatment can be an effective option in obese patients with MS, prediabetes and mild dyslipidaemia with further improvement of cardiovascular risk factors. We could not observe the increase rate of glucose intolerance in statin group. Future longitudinal studies are needed to test the benefits of early statin treatment compared with LSM.

Abstract
This study is a prospective multicenter study designed to investigate the effects of lipid-lowering therapy with pitavastatin on atherosclerotic plaque in patients with coronary heart disease, and to determine which factor is more closely associated with plaque regression. Participants (n = 63) were treated with pitavastatin for 12 months, and the carotid intima-media thickness (IMT) was measured by ultrasound before and after treatment. Mean IMT slightly but significantly decreased (from 0.99 ± 0.33 to 0.94 ± 0.28 mm for overall, P = 0.01) regardless of the presence of pretreatment with other statins. There were no significant relations with hs-CRP, malondialdehyde-LDL, LDL cholesterol, and smaller LDL cholesterol levels despite their decrease by pitavastatin. Decreases in mean IMT were observed significantly more frequently in subjects with high on-treatment HDL cholesterol levels than with low HDL cholesterol levels (P = 0.017). The change in mean IMT tended to be inversely correlated with increments in HDL cholesterol and apolipoprotein A-I. The IMT regression was more often observed in the absence of diabetes and metabolic syndrome. In conclusion, we demonstrated that treatment with pitavastatin attenuated atherosclerotic plaque. This effect was associated with the level of HDL cholesterol, and was stronger in the absence of diabetes and metabolic syndrome in our ischemic heart disease patients.

Abstract
BACKGROUND The JAPAN-ACS (Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome) trial showed that intensive statin therapy could induce significant coronary plaque regression in acute coronary syndrome (ACS). We evaluated the impact of metabolic syndrome (MetS) and its components on coronary plaque regression in the JAPAN-ACS patients. METHODS AND RESULTS Serial intravascular ultrasound measurements over 8-12 months were performed in 242 ACS patients receiving pitavastatin or atorvastatin. Patients were divided into groups according to the presence of MetS or the number of MetS components. Although the percent change in plaque volume (%PV) was not significantly different between the MetS (n=119) and non-MetS (n=123) groups (P=0.50), it was significantly associated with an increasing number of MetS components (component 0: -24.0%, n=7; components 1: -20.8%, n=31; components 2: -16.1%, n=69; components 3: -18.7%, n=83; components 4: -13.5%, n=52; P=0.037 for trend). The percent change in body mass index (%BMI) significantly correlated with %PV (r=0.15, P=0.021), especially in the MetS components 4 group (r=0.35, P=0.017). In addition, %BMI was an independent predictor of plaque regression after adjustment for the changes of low- and high-density lipoprotein cholesterol, triglycerides and HbA(1c). CONCLUSIONS The clustering of MetS components, but not the presence of MetS itself, could attenuate coronary plaque regression during intensive statin therapy in ACS patients. Therefore, to achieve a greater degree of plaque regression, it is necessary to treat to each MetS component and use lifestyle modification.

Abstract
AIMS: To compare the efficacy and safety of pitavastatin and atorvastatin in Japanese patients with hypercholesterolemia. METHODS AND RESULTS Japanese patients with total cholesterol (TC) > or = 220 mg/dL were randomized to receive pitavastatin 2 mg (n=126) or atorvastatin 10 mg (n=125) for 12 weeks. The primary endpoint was percent change from baseline in non-HDL-C level after 12 weeks of treatment. Reduction of non-HDL-C by pitavastatin treatment (39.0%, P=0.456 vs. atorvastatin) was non-inferior to that by atorvastatin (40.3%). Both pitavastatin and atorvastatin also significantly reduced LDL-C by 42.6% and 44.1%, TC by 29.7% and 31.1%, and TG by 17.3% and 10.7%, respectively, at 12 weeks without intergroup differences. HDL-C showed a significant increase at 12 weeks with pitavastatin treatment (3.2%, P=0.033 vs. baseline) but not with atorvastatin treatment (1.7%, P=0.221 vs. baseline). Waist circumference, body weight and BMI were significantly correlated with percent reduction of non-HDL-C in the atorvastatin group, whereas pitavastatin showed consistent reduction of non-HDL-C regardless of the body size. In patients with metabolic syndrome, LDL-C was reduced significantly more in patients receiving pitavastatin when compared with those receiving atorvastatin. AST, ALT and gammaGTP increased significantly in patients receiving atorvastatin but not in those receiving pitavastatin. Both treatments were well tolerated. CONCLUSION Pitavastatin 2 mg and atorvastatin 10 mg are equally effective in improving the lipid profile and were well tolerated in Japanese patients with hypercholesterolemia.
