Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined.
This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months.
This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

The use of lipid-modifying agents (LMAs) other than statins has rarely been reported in real clinical settings. We aimed to compare the initiation and subsequent use of LMA classes for prevention of cardiovascular diseases. Using the national claims database, this retrospective cohort study was conducted on patients aged ≥55 years who initiated to use statins, ezetimibe, or fibrates between Fiscal Years (FYs) 2014 and 2017 as the first pharmacotherapy for dyslipidemia in Japan. A permissible gap for defining persistence was set as the median days of supply of a class to an individual. Kaplan-Meier estimates were calculated for rates. Cohorts for primary prevention without/with risk and secondary prevention comprised 1307438, 908378, and 503059 initiators for statins; 44116, 34206, and 11373 for ezetimibe; and 124511, 96380, and 27751 for fibrates. The persistence rates declined shortly after the therapy initiation regardless of the classes, which was approximately 50% at 1 year for any class for primary prevention without risk. A notable sex difference in terms of persistence rates was observed only for statins of secondary prevention. The restarting rates were similar between prevention settings: approximately 50-60% for statins and 30-40% for ezetimibe and fibrates 1 year after first discontinuation. For ezetimibe and fibrates, approximately 10% of initiators were added or switched to statins within 1 year of initiation. Collectively, any class tended to be discontinued early and some restarted; however, there were some unique classes. The findings are useful for improvement of dyslipidemia therapy.

BACKGROUND: The lipid-lowering and anti-inflammatory effects of statins and fibrates may ameliorate periodontitis. Patients with hyperlipidemia tend to have a worse periodontal status. This study assessed the association between the use of statins/fibrates and the incidence of chronic periodontitis in patients with hyperlipidemia in Taiwan.
METHODS: This retrospective cohort study enrolled patients newly diagnosed with hyperlipidemia between 2001 and 2012 from the 2000 Longitudinal Generation Tracking Database and followed them for 5 years. The study population was divided into four groups: statin monotherapy, fibrate monotherapy, combination therapy (both statins and fibrates), and control (neither statins nor fibrates). Each patient in the treatment group was matched at a ratio of 1:1 with a control. Chronic periodontitis risk was compared in the three study arms by using a Cox proportional hazard model.
RESULTS: Chronic periodontitis risk was reduced by 25.7% in the combination therapy group compared with the control group (adjusted hazard ratio [aHR], 0.743; 95% confidence interval (CI), 0.678-0.815). Low dose (<360 cumulative defined daily dose [cDDD]) and shorter duration (<2 years) of statin monotherapy seem to be associated with an increased risk of chronic periodontitis; high dose (≥720 cDDD/≥1080 cDDD) and longer duration (≥3 years) of statin/fibrate monotherapy may be correlated with a lower risk of periodontitis. Hydrophobic statin users had a lower chronic periodontitis risk than hydrophilic statin users.
CONCLUSIONS: Chronic periodontitis risk was lower in patients with hyperlipidemia on combination treatment with statins and fibrates, and the risk decreased when patients used statins or fibrates for >3 years.

To evaluate recent clinical trials focusing on patients with hypertriglyceridemia.
Randomized clinical trials have recently been undertaken in hypertriglyceridemic patients to determine whether effective reductions in triglycerides would improve cardiovascular disease (CVD) outcomes. However, the fibric acid derivative, pemafibrate, failed to reduce cardiovascular events despite significant reductions (~ 25-35%) in triglyceride levels and despite background statin therapy. In contrast, icosapent ethyl, a highly purified omega-3 fatty acid was previously shown to reduce CVD events in hypertriglyceridemic patients, despite more modest reductions (~ 20%) in triglyceride levels in statin treated patients. The divergent results obtained in patients with hypertriglyceridemia (HTG), a group at particularly high risk of CVD, especially when coupled with other risk factors, indicates that triglyceride lowering in of itself is insufficient to offset CVD risk. Rather, the effectiveness of therapy in this high-risk cohort may be the result of the suppression of the inherent atherogenic properties associated with HTG.

Post hoc analyses of previous fibrate trials have suggested that individuals with type 2 diabetes mellitus with high triglyceride levels and low HDL-cholesterol levels benefit from fibrate therapy even when the overall trial results were neutral. However the PROMINENT (Pemafibrate to Reduce Cardiovascular Outcomes by Reducing Triglycerides in Patients with Diabetes) trial seems to close the door for fibrates. The trial found that fibrates do not reduce the risk of cardiovascular disease among individuals with type 2 diabetes and high triglyceride levels and low HDL cholesterol levels, despite triglyceride lowering. The results of PROMINENT suggest that triglyceride lowering without decreases in the plasma concentration of atherogenic lipoproteins are unlikely to decrease the risk of cardiovascular disease. These results also highlight the importance of rigorously confirmation of post hoc findings before implementation in clinical practice.

OBJECTIVE: The purpose of this study is to evaluate the association between lipid-lowering agent use and the risks of diagnosed dry eye disease (DED).
METHODS: This retrospective, case-control study included 780 786 patients who received lipid-lowering agents in 2002-2016, of which 17 409 were newly diagnosed with DED during a ≥2-year follow-up period. These patients were matched 1:4 with control participants for age, sex, and comorbidities. Separate odds ratios (OR) were calculated for DED and each of statin and fibrate use.
RESULTS: Statin users had significantly higher odds of DED (adjusted OR = 1.12; 95% confidence interval (CI) = 1.08-1.16, p < 0.0001) than nonusers. Fibrate users did not show higher odds of DED than nonusers (adjusted OR = 1.04; 95% CI = 0.99-1.10, p = 0.125). The lipophilic statin users did not show higher odds of DED compared with the hydrophilic statin users (adjusted OR = 0.99, 95% CI = 0.93-1.06, p = 0.729). Among statin users, the odds of DED did not differ significantly between patients receiving statin therapy for >180 days vs. ≤90 days or patients receiving statin therapy for 91-180 days vs. ≤90 days (adjusted OR = 1.00, p = 0.922; adjusted OR = 0.94, p = 0.541, respectively). The odds of DED were not statistically different among patients receiving low-intensity, moderate-intensity, and high-intensity of statin therapy.
CONCLUSIONS: Patients receiving statin therapy had a higher DED risk than patients not receiving statin therapy. The type of statin, the duration, and the intensity of statin use were not significantly associated with DED risks. Further studies are required to identify the relevant factors related to DED risks with statin.

This study aimed to investigate the associated risk between using fibrate and open-angle glaucoma (OAG) in hyperlipidemic patients from the National Health Insurance Research Database (NHIRD).
We collected data over a 16-year period from the NHIRD, and used the Fisher\'s exact test and Pearson chi-square test to analyze variables. Adjusted hazard ratios (aHR) were used to examine the risk factors for disease development. We applied Kaplan-Meier analysis to compare the cumulative incidence of OAG.
A total of 10,011 patients using fibrate were enrolled in the study cohort, and 40,044 patients not using fibrate were enrolled in the control cohort. The incidence of OAG was lower in the study cohort than in the control cohort (aHR = 0.624, p = 0.007). The overall incidence of OAG was 463.02 per 100,000 person-years in the study cohort and 573.65 per 100,000 person-years in the control cohort. We used the Kaplan-Meier method to calculate the cumulative risk of developing OAG. The results revealed that after using fibrate for over seven years, the study cohort had a greatly lower rate of developing OAG than the control cohort (log-rank test p = 0.050).
Our studies showed that using fibrate for over seven years may lead to a lower risk of OAG in patients with hyperlipidemia. Nevertheless, further prospective studies that comprehensively investigate the relationship between using fibrate and OAG are needed.

BACKGROUND: Several observational studies have found that statins may materially decrease the risk of chronic obstructive pulmonary disease (COPD) exacerbations. However, most of these studies used a prevalent user, non-user comparison approach, which may lead to overestimation of the clinical benefits of statins. We aimed to explore the risk of COPD exacerbations associated with statins with a new user, active comparison approach to address potential methodological concerns. We selected fibrates, another class of lipid-lowering agents, as the reference group because no evidence suggests that fibrates have an effect on COPD exacerbations.
METHODS: We identified patients with COPD who initiated statins or fibrates from a nationwide Taiwanese database. Patients were followed from cohort entry to the earliest of the following: hospitalization for COPD exacerbations, death, end of the data, or 180 days after cohort entry. Stratified Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of COPD exacerbations comparing statins with fibrates after variable-ratio propensity score (PS) matching and high-dimensional PS (hd-PS) matching, respectively.
RESULTS: We identified a total of 134,909 eligible patients (110,726 initiated statins; 24,183 initiated fibrates); 1979 experienced COPD exacerbations during follow-up. The HRs were 1.10 (95% CI, 0.96 to 1.26) after PS matching and 1.08 (95% CI, 0.94 to 1.24) after hd-PS matching. The results did not differ materially by type of statins and patient characteristic and did not change with longer follow-up durations.
CONCLUSIONS: This large-scale, population-based cohort study did not show that use of statins was associated with a reduced risk of acute exacerbations in patients with COPD using state-of-the-art pharmacoepidemiologic approaches. The findings emphasize the importance of applying appropriate methodology in exploring statin effectiveness in real-world settings.

Drug-induced myopathies are classified as acquired myopathies caused by exogenous factors. These pathological conditions develop in patients without muscle disease and are triggered by a variety of medicaments, including lipid-lowering drugs (LLDs) such as statins, fibrates, and ezetimibe. Here we summarise the current knowledge gained via studies conducted using various models, such as cell lines and mammalian models, and compare them with the results obtained in zebrafish (Danio rerio) studies. Zebrafish have proven to be an excellent research tool for studying dyslipidaemias as a model of these pathological conditions. This system enables in-vivo characterization of drug and gene candidates to further the understanding of disease aetiology and develop new therapeutic strategies. Our review also considers important environmental issues arising from the indiscriminate use of LLDs worldwide. The widespread use and importance of drugs such as statins and fibrates justify the need for the meticulous study of their mechanism of action and the side effects they cause.

The aims of the present study were to investigate the effects of fenofibrate and bezafibrate on the risk of development of diabetic retinopathy (DR) in patients with type 2 diabetes and dyslipidemia. Japanese working age patients with type 2 diabetes and dyslipidemia were extracted from the Nihon University School of Medicine Clinical Data Warehouse. These patients were divided into three groups: control group (n=2549), fenofibrate group (n=40), and bezafibrate group (n=135). Multivariate logistic regression analysis was performed to assess the association between fibrates and the development of DR. After adjustment for covariates, fenofibrate showed no association with the risk of DR [adjusted odds ratio (OR), 0.160; 95% CI, 0.021-1.209; p=0.0758]. Bezafibrate also showed no association with the risk of DR (adjusted OR, 0.731; 95% CI, 0.411-1.299; p=0.2855). However, poor control of hemoglobin A1c (HbA1c ≥8.0%; adjusted OR, 3.623; 95% CI, 2.649-4.956; p<0.0001) and high low-density lipoprotein cholesterol (LDL-C ≥140 mg/dL; adjusted OR, 1.399; 95% CI, 1.013-1.932; p=0.0415) within the follow-up period of type 2 diabetes and dyslipidemia increased the risk of DR. Our results suggested that to prevent development of DR in patients with type 2 diabetes and dyslipidemia, controlling LDL-C levels as well as HbA1c levels under coexistence type 2 diabetes and dyslipidemia is more important than the selection of fibrate.
