BACKGROUND: The combination therapy of HMG CoA reductase inhibitor (statin) and fibrate is more effective than each ones in managing combined dyslipidemia. However, this therapy tends to be avoided due to potential risk of rhabdomyolysis. The aim of the study was to reevaluate the efficacy and safety of combination therapy. METHODS: A total 61 patients were divided into three groups according to lipid levels and medications; statin+fibrate group (n=10), statin group (n=31) and fibrate group (n=18). Patients with active hepatitis or renal dysfunction who were at high risk for complications were excluded. Lipid profiles were measured before and 2 months after medications. RESULTS: Combination therapy markedly decreased total cholesterol, low density lipoproteincholesterol (LDL-C) and triglyceride concentrations (p=0.008, p=0.028 and p=0.018 respectively), and increased high density lipoprotein-cholesterol (HDL-C)(p=0.028). The effects of this therapy on HDL-C and triglyceride were more potent than those of statin. Combination therapy was more effective in lowering LDL-C than fibrate. Serious complications such as myopathy and marked elevation of transaminase level were not observed in all groups. In statin+fibrate group, transaminase level was elevated slightly above the normal range in two cases. Creatine kinase level showed the trend to increase with borderline significance. However the levels were within normal range in 9 cases and elevated twofold in one patient. CONCLUSION: Combination therapy of statin and fibrate was effective in combined dyslipidemia and well tolerated in patients without high risk for the complications although the number of cases was small to get a conclusion.

Philippine Journal of Neurology 2004;8(1):1-5
OBJECTIVE: To determine the histopathological effect of statins, fibrates and its combination in rat nerves
METHODOLOGY: This is a pilot experimental study. Four male albino rats were used in this study. Each rat was given therapeutic doses of simvastatin alone, gemfibrozil alone, gemfibrozil and simvastatin combination and placebo. On day 21, the sciatic nerve was harvested for histopathologic examination
RESULTS: Although not marked, the combination of simvastatin and gemfibrozil produced more axonal degeneration than did simvastatin alone or gemfibrozil alone. Axonal degeneration was documented on teased nerve fibers and epon cross sections
CONCLUSION: The use of lipid lowering agents may induce peripheral neuropathy Recommendation: This pilot study serves as rationale to proceed with an experiment not only to document neuropathy but also correlate the possible association of the pathomechanism of myotoxicity and neurotoxicity of lipid lowering agents.

The aim of this study is to establish a simple and stable model like poloxamer 407 (P-407)-induced dyslipidemia of golden hamster model, and investigate the mechanism of lipid metabolism disturbance in this model. PPARalpha agonist and HMG-CoA reductase inhibitor were administrated to validate the efficacy on regulating lipid metabolism in the dyslipidemia golden hamster model. Six weeks male golden hamsters were chosen to inject P-407 intraperitoneally at a bolus dose of 300 mg x kg(-1), an intermittent injection at a dose of 200 mg x kg(-1) every 72 hours after the bolus. The results showed that P-407-induced golden hamster model characterized as increased serum triglyceride (TG), total cholesterol (TC), free cholesterol (free-CHO), cholesteryl ester (CE), free fatty acids (FFA) and apoB levels, and the hyperlipidemia state maintained at a stable level persistently. Meanwhile, augmented malondialdehyde (MDA) and nitric oxide (NO) level was observed. LCAT and SR-B I mRNA levels in liver of model group were down-regulated (expression ratio is 0.426; 0.783), while HMG-CoA reductase mRNA level was up-regulated (expression ratio is 1.493) compared with those of the normal group. The serum cholesterol and triglyceride levels were significantly lower in P-407-induced dyslipidemia hamster model after treated with atorvastatin (Ato) at a dose of 50 mg x kg(1) or fenofibrate (Fen) at 100 mg x kg(-1) for two weeks. These findings suggest that serum lipid distribution in dyslipidemia golden hamster is similar to that of human, and which may be relevant to the disturbance of the enzymes expression involved in lipid metabolism in liver. Results obtained from this study support the concept that dyslipidemia golden hamster may be an adequate animal model to evaluate the efficacy of lipid-lowering agents.

Objective: To assess low-density lipoprotein cholesterol (LDL-C) levels and use of lipid-lowering treatment among young and middle-aged ultra-high-risk patients with acute coronary syndrome (ACS) in China. Methods: The study was based on the"Improving Care for Cardiovascular Disease in China (CCC)-ACS"project, a collaborative registry by and Chinese Society of Cardiology (CSC) and the American Heart Association. Hospitalized-patients with ACS were consecutively enrolled from 159 tertiary and 82 secondary hospitals across China, related clinical information was collected. This study included young and middle-aged hospitalized patients (18-59 years) with ACS from November 2014 to December 2019 registered in CCC-ACS project. Ultra-high-risk was defined according to Chinese expert consensus on lipid management of ultra-high-risk atherosclerotic cardiovascular disease (ASCVD) patients of CSC. The mean LDL-C levels at admission, pre-hospital lipid-lowering therapy and proportion of patients with LDL-C target achieved were analyzed. Results: A total of 42 230 patients younger than 60 years with ACS were included in this study. The mean age was (50.4±6.9) years, and 86.8% (36 676/42 230) of the ACS patients were male. Among them, 86.9% (36 687/42 230) met the criteria of ultra-high-risk. The mean level of LDL-C at admission was (2.8±1.0)mmol/L, only 5.3 % (1 948/36 687) patients achieved the targeted goal of LDL-C<1.4 mmol/L. Among the ultra-high-risk ASCVD patients, 17.5% (6 430/36 687) received lipid-lowering drugs before hospitalization, 96.4% (6 198/6 430) of whom received statins monotherapy. Among patients receiving pre-hospital statins, only 9.9% (626/6 323) patients reached an LDL-C<1.4 mmol/L at admission. Conclusions: The majority of young and middle-aged hospitalized patients with ACS are ultra-high-risk patients for ASCVD in China. Pre-hospital lipid-lowering drugs use is lower in these ultra-high-risk ASCVD patients and most patients do not reach the new LDL-C target level at admission.

8.Effect of Taizhi'an capsule combined with Simvastatin on hyperlipidemia in diabetic patients.
Chinese journal of integrative medicine 2006;12(1):24-28
OBJECTIVETo evaluate the effectiveness and safety of Taizhi'an (TZA) capsule combined with Simvastatin (Sim) in treating hyperlipidemia in diabetes mellitus (DM) patients.
METHODSEighty cases of type 2 DM patients with hyperlipidemia were randomized into two groups, 40 in each group. The patients in the treated group took orally TZA capsules at the dose of 0.9 g 3 times a day and Sim 10 mg at bedtime. And the patients in the control group were treated with Sim 20 mg alone at bedtime. Both regimens lasted for 12 weeks. Before and after the study the changes of blood lipid levels and adverse reaction were investigated.
RESULTSThe serum levels of total cholesterol (TC), triglycerides (TG) and low density lipoprotein-cholesterol (LDL-C) were decreased respectively by 28.8%, 18.2% and 26.3% in the treated group; and by 29.4%, 19.4% and 24.6% in the control group. On the contrary, high density lipoprotein-cholesterol (HDL-C) was increased by 23.5% in the treated group and by 29.4% in the control group. All these changes were statistically significant before and after treatment (all P < 0.05), but they did not differ statistically between the two groups (P > 0.05). There was no significant changes in hemoglobin A(1)c (HbA(1)c). Patients in the treated group did not develop any adverse reactions. However, ALT was found to be higher above the normal range in 5% of the patients in the control group.
CONCLUSIONIn treating hyperlipidemia in DM patients, combination of TZA with Sim 10 mg taken daily achieved satisfactory efficacy which was similar to Sim 20 mg daily alone. But the combination therapy conducted in the treated group proved to be better in safety, and could overcome adverse reactions resulting from Sim that was seen in the control group.

Twenty four hyperlipidemic patients, consist of 13 males and 11 females, were administration a new hypolipidemic agents, Pantethine, and blood lipid level were checked sereally for 16 weeks. The following results are obtained. 1. The serum high density lipoprotein-cholesterol are markedly increased by 11.8%. 2. The serum cholesterol level are reduced mildly by 4.8% & it seems to be insignificant. 3. The serum triglyceride level are moderately reduced by 10.7%. 4. In 11 female patients, pantethine are more than effect on male patients. 5. Pantethine has been well tolerated in most patients. With a consideration of remakable safety, it is promising that pantethine are effective in reducing cholesterol, Triglyceride and increasing high density lipoprotein-cholesterol level.

OBJECTIVETo assess the current status in dietary treatment of hypercholesterolemia and its effects on control of this disease in China.
METHODSTwenty five Tertiary-A hospitals from 12 provinces in China were selected, in which 2136 patients were recruited who had had hypercholesterolemia and had been receiving lipid lowering treatment for at least 2 months. Serum lipids level was determined for each patient at the time of enrollment, and using a simplified food frequency method carried out dietary intake survey. Patients who take meat of less than 75 g per day and eggs of less than 5 per week, and fried foods of less than 5 times per week, and butter cakes and pastry of less than 5 times per week were considered as having their diet controlled.
RESULTSAmong 1746 responded patients, 68.3% reported having controlled diet. Among those reported "controlled", 75% had a diet meeting the requirements suggested by the Chinese Recommendations on Prevention and Treatment of Hypercholesterolemia (CRPTH). The percentage of patients having their serum total cholesterol under control in diet controlled group, according to the CRPTH, was significantly higher than that in diet uncontrolled group (28.8% vs 13.6%, P < 0.01). After adjustment for drug treatment and other covariates, the diet controlled group showed a significantly higher rate in control of hypercholesterolemia than the diet uncontrolled group (OR = 2.7, 95% CI: 1.4 approximately 5.2).
CONCLUSIONDiet control significantly improves the status in control of hypercholesterolemia and thus should be reinforced in routine clinical practice.
