Small, dense low-density lipoprotein (LDL) is an atherogenic lipoprotein because of its susceptibility to oxidative modification. However, evaluating LDL size requires highly sophisticated techniques. We investigated potentially convenient biochemical parameters for assessing the presence of small, dense LDL. Thirty-nine male subjects, who had been involved in a work-site health promotion program, were recruited. Subjects were divided into two groups: normal LDL size (> 25.5 nm, Normal LDL group) and small LDL (≤ 25.5 nm, Small LDL group). Significant negative correlations were observed between LDL size and both triglyceride (TG) (p < 0.001) and remnant-like particle cholesterol concentrations (p < 0.01), while there was a significant positive correlation between LDL size and the high density lipoprotein cholesterol (HDL-C) concentration (p < 0.01). The TG concentration was a negative and the HDL-C concentration a positive independent variable predicting LDL size in multiple regression analysis (p < 0.0001). Seventy-five percent of the Small LDL group had TG/HDL-C ratios higher than 0.9 using mmol/L or 2.0 using mg/dL, while only 25% of the normal LDL group had ratios above the levels (p = 0.0013). A combined parameter, the TG/HDL-C ratio, is beneficial for assessing the presence of small LDL.

Background:The ODYSSEY Japan study was designed to demonstrate the reduction in low-density lipoprotein cholesterol (LDL-C) by alirocumab as add-on to existing lipid-lowering therapy in Japanese patients with heterozygous familial hypercholesterolemia (heFH) or non-FH at high cardiovascular risk who require additional pharmacological management to achieve their LDL-C treatment goal (<2.6 or <3.1 mmol/L, depending on risk category).Methods and Results:This randomized, double-blind, parallel-group, 52-week study was conducted in Japan. Patients (n=216) with heFH, non-FH at high cardiovascular risk with coronary disease, or classified as category III were enrolled. The prespecified safety analysis was done after the last patient completed 52 weeks. Patients were randomized (2:1, alirocumab:placebo) with stratification for heFH to s.c. alirocumab (75 mg every 2 weeks [Q2 W] with increase to 150 mg if week 8 LDL-C ≥2.6/3.1 mmol/L) or placebo for 52 weeks plus stable statin therapy. At week 24, mean±SE change in LDL-C from baseline was –62.5±1.3% in the alirocumab group and 1.6±1.8% in the placebo group (difference, –64.1±2.2%; P<0.0001); the reduction was sustained to week 52 (alirocumab, –62.5±1.4%; placebo, –3.6±1.9%). No patterns were evident between treatment groups for adverse events at 52 weeks.Conclusions:In high-risk Japanese patients with hypercholesterolemia on stable statin therapy, alirocumab markedly reduced LDL-C vs. placebo and was well tolerated over 52 weeks.

Aim: To examine the efficacy and safety of alirocumab in Japanese patients with dyslipidemia with or without diabetes mellitus (DM).Methods: Patients (n=216) with heterozygous familial hypercholesterolemia (heFH), non-FH at high cardiovascular risk with coronary artery disease (CAD), or category III (primary prevention) were enrolled; 148 (68.5%) patients had a diagnosis of DM at baseline. Patients were randomized (2:1), with stratification factor (heFH, non-FH), to alirocumab (75 mg every 2 weeks [Q2W] with increase to 150 mg if week 8 LDL-C was above predefined limits) or placebo subcutaneously for 52 weeks on top of stable statin therapy.Results: At Week 24, least square (LS) mean±standard error changes in low-density lipoprotein cholesterol (LDL-C) concentration from baseline in alirocumab-treated patients were -63.1±1.6% and -60.8±2.7% in those with and without DM. These LDL-C reductions were maintained to Week 52: -63.0±1.6% (LS mean difference vs placebo -62.4±3.0%; P<0.0001) with DM and -61.3±2.8% (LS mean difference vs placebo -53.4±4.0%; P<0.0001) without DM. The most common adverse events in the alirocumab group were nasopharyngitis, back pain, injection site reaction, and fall. No particular safety signals or concerns were noted between DM and non-DM groups at 52 weeks. A dose-increase in alirocumab from 75 to 150 mg Q2W was necessary in two heFH patients, neither of whom had DM.Conclusions: In high-cardiovascular-risk Japanese patients with hypercholesterolemia on stable statin therapy, alirocumab produced substantial and sustained LDL-C reductions throughout the 52-week study regardless of DM status at baseline, with a similar safety profile to placebo.

Japan achieved remarkable economic development after World War II, which has led remarkable changes in risk factors of atherosclerotic diseases and led to epidemiological transition in Japan. Nowadays, obesity is pandemic around world, which is same case in Japan. BMI of Japanese population, especially young adult men increased gradually since the 1960s associated with increase in intake of fat as well as decrease in intake of rice, which has been revealed by the annual report of the Ministry of Health, Labour and Welfare. Such changes suggest the change of dietary habit from Japanese style to westernized style. In recent years such changes in lifestyle has been accompanied by a gradual increase in serum cholesterol in the Japanese population, which is associated with increase in the incidence of cardiovascular diseases (CVD). Japanese guidelines recommend “The Japan diet” to prevent CVD, because there are several epidemiological data to show the cardio-preventive effect of fish, soy bean, and vegetables, which are the major component of “The Japan Diet”. It is very important to recognize the diet habit is one of culture and that rice plays a pivotal role in “The Japan Diet”.

Background:To understand the recent management status in Japan, we determined the low-density lipoprotein cholesterol (LDL-C) goal attainment (GA) rate of patients initiating statin monotherapy for dyslipidemia.Methods and Results:Dyslipidemic patients undergoing either primary prevention with high cardiovascular risk or secondary prevention (defined by 2012 Japan Atherosclerosis Society Guidelines) were retrospectively analyzed from a hospital-based claims database. In both groups, the LDL-C levels and GA rates of patients treated with intensive or standard statin monotherapy for ≥4 weeks (January 2012–August 2016) were evaluated. Among 1,501,013 dyslipidemic patients, 11,695 and 9,642 were included in the primary and secondary prevention groups, respectively. A total of 94% of patients underwent statin monotherapy as the initial lipid-lowering therapy, of which most (≥80%) took intensive statins. The proportions of patients in the primary prevention group who achieved an LDL-C goal <120 mg/dL by intensive and standard statins were 81.1% and 61.2%, respectively, and the proportions of those who achieved a goal <100 mg/dL in the secondary prevention group were 73.3% and 48.1%, respectively. The GA rates were similar regardless of disease complications.Conclusions:Most patients (>70%) in both groups achieved LDL-C management goals using intensive statin monotherapy. Further treatment approaches are required for high-risk patients not achieving LDL-C goals by initial statin monotherapy. Continuous efforts are crucial for adherence and persistence of lipid-lowering therapies.

To determine the prevalence of metabolic syndrome in the Japanese general population, we analyzed data from a nationwide survey conducted in 2000. According to the Japanese new diagnostic criteria for metabolic syndrome in 2005, we analyzed 3,264 people aged from 20 to 79 (men, 1,917; women, 1,347) from the total participants. The incidence of metabolic syndrome was 7.8%. Men had a higher incidence (12.1%) than women (1.7%). Most of the women satisfying the criteria were 50 years old or over, while the incidence in men started to rise from their 30s. When we applied the criteria of Adult Treatment Panel III, the incidence was about 3-fold higher. In this population visceral obesity was associated with metabolic abnormalities, such as higher LDL-cholesterol, triglyceride, glucose, and blood pressure and lower HDL-cholesterol. Thus we determined the incidence of metabolic syndrome and each metabolic abnormality in the Japanese general population in 2000 and found an association of visceral obesity with metabolic abnormalities. Intervention to reduce the incidence of metabolic syndrome in Japan is necessary to reduce the risk of cardiovascular disease.

Background: Treatment with evolocumab reduces mean low-density lipoprotein cholesterol (LDL-C) up to 75% and cardiovascular events by 16% in the first year and 25% thereafter. Methods and Results: Japanese patients with hypercholesterolemia enrolled in the parent YUKAWA-1-2 studies could enroll, once eligible, in the OSLER studies (n=556). OSLER re-randomized patients 2:1 to evolocumab plus standard of care (SOC; evolocumab+SOC) or SOC alone for 1 year; after year 1, patients could enter the all-evolocumab+SOC open-label extension of OSLER. Patients received evolocumab+SOC from the 2nd year through up to 5 years. Long-term efficacy and safety, including antidrug antibodies, were evaluated. Of 556 patients, 532 continued to the all-evolocumab+SOC extension: mean (standard deviation [SD]) age 61 (10) years, 39% female. A total of 91% of 532 patients completed the studies. Mean (SD) LDL-C change from parent-study baseline with evolocumab from a mean (SD) baseline of 142.3 (21.3) and 105.0 (31.1) mg/dL in OSLER-1 and OSLER-2, respectively, was maintained through the end of the study: −58.0% (19.1%) at year 5 in OSLER-1, −62.7% (25.6%) at year 3 in OSLER-2. The overall safety profile of the evolocumab+SOC periods was similar to that of the year-1 controlled period. Antidrug antibodies were detected transiently in 3 patients. No neutralizing antibodies were detected. Conclusions: Japanese patients who continued evolocumab+SOC for up to 5 years experienced sustained high LDL-C level reduction. Long-term evolocumab+SOC exposure showed no new safety signals.

We studied the association of six common polymorphisms of four genes related to lipid metabolism with serum lipid levels. We selected single-nucleotide polymorphisms (SNPs) in the genes for cholesteryl ester transfer protein (CETP), lipoprotein lipase (LPL), hepatic lipase (LIPC), and apolipoprotein CIII (APOC3), and studied 2267 individuals randomly selected from the participants of Serum Lipid Survey 2000. There was a significant association of CETP polymorphism (D442G, Int14 +1 G → A, and TaqIB), LPL polymorphism (S447X), and LIPC polymorphism (−514 → CT) with HDL-cholesterol levels. We also found a significant association of LPL polymorphism (S447X) and APOC3 polymorphism (SstI) with triglyceride levels. This is the largest database showing the association of common genetic variants in lipid metabolism with serum lipid levels in the general Japanese population. Further study is necessary to elucidate the role of these gene polymorphisms in cardiovascular events.

Aim: The Japan Diet (JD) recommended by the Japan Atherosclerosis Society based on the traditional Japanese diet is presumably favorable for preventing atherosclerotic cardiovascular diseases, but few high-quality controlled clinical trials have examined its benefits as compared with other diets. We studied effects of nutrition education for JD intake as compared with partial JD (PJD) intake on serum lipids and inflammatory parameters in subjects with dyslipidemia. Methods: A randomized parallel controlled clinical trial was conducted on outpatients with dyslipidemia. Participants were randomly divided into the JD or the PJD group. Face-to-face nutrition education based on each diet at baseline and at 3 months, as well as monthly counseling by mail during the intervening 3-month period, were provided and participants practiced up to 6 months. Both groups were advised to reduce consumptions of animal fat/ fatty meat/poultry, confections, and alcoholic drinks. Additionally, the JD group participants were recommended to consume more fish, soybean products especially natto, vegetables, and seaweed/mushrooms/konjak, and to switch from refined to unrefined cereals or barley. Results: Mean LDL-cholesterol was 125 +/- 29 mg/dL at baseline, and the JD group ( n=49) showed a greater mean LDL-cholesterol decrease than the PJD group (n=49) [- 8 mg/dL in JD vs 1 mg/dL in PJD, difference, -9 mg/dL (95%CI, -17 to 0) p=0.043)], and triglyceride (p=0.023) and insulin (p=0.033) reductions were larger in the JD group than in the PJD group at 6 months. Conclusion: Nutrition education for JD intake was suggested to improve serum lipid and metabolic parameters in patients with dyslipidemia.

Background:Evolocumab is the first monoclonal antibody against proprotein convertase subtilisin/kexin type 9 (PCSK9) approved in Japan for the treatment of patients with familial hypercholesterolemia (FH) and hypercholesterolemia (HC). This study assessed the 12-week effectiveness and safety of low-density lipoprotein cholesterol (LDL-C)-lowering therapy by PCSK9 inhibition in patients with FH (homozygous [HoFH] or heterozygous [HeFH]) and HC by analyzing evolocumab data collected in the real-world setting in Japan.Methods and Results:Overall, 427 patients (mean±SD age, 61.6±13.8 years; female, 38.4%; 28 HoFH, 320 HeFH, 79 HC), enrolled from 299 clinical sites, were included in the safety analysis set. The major cardiovascular risk factors were coronary artery disease (77.3%), diabetes mellitus/impaired glucose tolerance (38.6%), and hypertension (65.1%). Median follow-up duration was 85.0 days. After 12 weeks of evolocumab treatment, the mean±SD percent change from baseline in LDL-C was −45.5%±27.0% (n=23) in HoFH (P<0.001 vs. baseline; t-test), −54.2%±29.0% (n=280) in HeFH (P<0.001), and −64.6%±22.4% (n=72) in HC (P<0.001) patients. The incidence of adverse drug reactions was 5.4% (23/427).Conclusions:Results suggest that patients receiving evolocumab treatment in the real-world setting were predominantly those with FH and HC in the secondary prevention group. LDL-C-lowering effectiveness with evolocumab was observed in FH (both HoFH and HeFH) and HC patients.

Background: YUKAWA is a 12-week, randomized, double-blind, placebocontrolled, phase 2 study evaluating the efficacy and safety of evolocumab (AMG 145) in statin-treated Japanese patients at high cardiovascular risk. Methods and Results: 310 eligible patients receiving stable statin (±ezetimibe) therapy were randomized to 1 of 6 treatments: placebo every 2 weeks (Q2W) or monthly (QM), evolocumab 70mg or 140mg Q2W, or evolocumab 280mg or 420mg QM. The primary endpoint was the percentage change from baseline in low-density lipoprotein cholesterol (LDL-C) measured by preparative ultracentrifugation (UC). Secondary endpoints included percentage changes in other lipid parameters and the proportion of patients with LDL-C <1.8mmol/L. Mean (SD) age was 62 (10) years; 37% were female; and the mean (SD) baseline LDL-C was 3.7 (0.5) mmol/L (by UC). Mean (SE) changes vs. placebo in LDL-C were greatest in the high-dose groups: −68.6 (3.0) % and −63.9 (3.2) % with 140mg Q2W and 420mg QM dosing, respectively. Up to 96% of evolocumab-treated patients achieved LDL-C <1.8mmol/L. Adverse events (AEs) were more frequent in evolocumab (51%) vs. placebo (38%) patients; 4 patients taking evolocumab discontinued treatment because of an AE. There were no significant differences in AE rates based on dose or dose frequency. Conclusions: In Japanese patients at high cardiovascular risk with hypercholesterolemia on stable statin therapy, evolocumab significantly reduced LDL-C and was well tolerated during this 12-week study.
