Three decades of lipid-lowering therapy in type 2 diabetic patients with angiographically proven stable coronary artery disease

Abstract Lipid-lowering therapy (LLT) is key to reducing the burden of macrovascular diabetes complications. Here, we aim to assess long-term trends in LLT and LDL-C levels among patients with type 2 diabetes (T2DM) with angiographically proven coronary artery disease (CAD). We investigated T2DM patients (n=590), who were referred to elective coronary angiography and were diagnosed with CAD in one of three observational cohort studies (OS) spanning 25 years: OS1: 1999-2000 (n=190); OS2: 2005-2008 (n=241); OS3: 2022-2023 (n=159). These studies were conducted at the same cardiology unit of a tertiary care hospital in Central Europe. The proportion of patients receiving statin therapy (C10AA and C10AB) increased significantly from 57.9% in OS1 to 64.3% in OS2 and 78.6% in OS3 (ptrend<0.001). Further, there was an increase in patients receiving high-intensity statin therapy, rising from none in OS1 to 8.5% in OS2 and 73.4% in OS3 (ptrend<0.001). The proportion of patients receiving more than one LLT compound also increased (OS1: 2.1%; OS2: 2.1%; OS3: 35.2%; ptrend<0.001). Use of ezetimibe (C10AX09) increased (OS1: 0.0%; OS2: 1.2%; OS3: 39.0%; ptrend<0.001) and fibrate use (C10AB) decreased (OS1: 5.3%; OS2: 3.3%; OS3: 0.6%; ptrend=0.015). Newly approved compounds (C10AX13 - C10AX16) were prescribed for 3.8% of patients in OS3. Among statin combination therapies, ezetimibe was predominantly used (93.5%). Mean LDL-C levels declined significantly from 123±38 mg/dL (OS1) to 115±39 mg/dL (OS2) and 77±38 mg/dL (OS3; ptrend<0.001). However, only 2.2% of patients in OS1, 2.5% in OS2 and 32.1% in OS3 reached an LDL-C target of <55 mg/dL (ptrend<0.001). This analysis suggests an upward trend in treatment intensity and a substantial improvement in LDL-C levels among T2DM patients with CAD. However, the majority of these patients still does not reach their LDL-C target.

Risk of Venous Thromboembolism in Statin Users Compared to Fibrate Users in the United Kingdom Clinical Practice Research Datalink (UK CPRD) GOLD.

A substantial proportion of adults receive statins for treatment of hypercholesterolemia and cardiovascular risk, and statins have been found to improve outcomes in this patient population. However, studies have not consistently demonstrated the potential benefits of statins in preventing venous thromboembolism (VTE). Therefore, we conducted this study to investigate this association. We conducted a cohort analysis in a study sample comprised of 40-79-year-old patients with hyperlipidemia who received at least one fibrate or statin prescription between January 1995 and December 2018 in the United Kingdom Clinical Practice Research Datalink (CPRD) GOLD. We evaluated the association between statin use and incident unprovoked VTE, compared to fibrate use, an active comparator, using Kaplan-Meier (KM) analysis, Poisson regression (with and without propensity score matching), and inverse probability of treatment weights (IPTW) marginal structural models (MSM). In this cohort of 166,292 patients with hyperlipidemia, 0.81% (N=1,353) developed incident unprovoked VTE. In analyses using the KM method, patients who received statins had a slightly lower risk of VTE compared to those who received fibrates (Log rank test: p=0.0524). The adjusted incident rate ratio (95% CI) for VTE, calculated using Poisson regression, controlling for serum cholesterol and other baseline covariates, in patients prescribed statins compared to fibrates was 0.77 (0.45-1.33) in the full cohort, 0.74 (0.38-1.45) in the propensity score matched analysis, and 0.51 (95% conservative CI: 0.34-0.76) in the IPTW MSM analysis. While the magnitude of effect varied across the different analytic methods, there is consistent evidence for a protective effect of statin use on the occurrence of unprovoked VTE.

Severe Hypertriglyceridemia in Patients with Type 2 Diabetes Mellitus Participating in the AMD Annals Initiative.

Background: Familial chylomicronemia syndrome (FCS) is a rare inherited condition due to lipoprotein lipase deficiency, characterized by hyperchylomicronemia and severe hypertriglyceridemia. Diagnosis is often delayed, thus increasing the risk of acute pancreatitis and hospitalization. Hypertriglyceridemia is a common finding in patients with type 2 diabetes (T2D), who may harbor FCS among the most severe forms. Aim of the Study: We investigated the prevalence and clinical characteristics associated with severe hypertriglyceridemia in a range indicative of FCS, in a large population of subjects with T2D. Methods: Within the large population of the AMD Annals Initiative, patients with T2D with a lipid profile suggestive of FCS [triglycerides >880 mg/dL and/or high-density lipoprotein (HDL)-cholesterol <22 mg/dL or non-HDL-cholesterol ≤70 mg/dL] and their clinical features have been identified. Results: Overall, 8592 patients had triglyceride values >880 mg/dL in a single examination, 613 in two examinations, and 34 in three or more measurements. Patients with high triglyceride levels were mostly male (80%), with a relatively young age (54 years), short duration of diabetes (6.3 years), and elevated hemoglobin A1c (HbA1c) levels (9.4%). By stratifying this group of patients according to the severity of hypertriglyceridemia, more severe hypertriglyceridemia (triglyceride levels ≥2000 mg/dL) was associated with an even younger age (52 vs. 54 years), even higher mean HbA1c values (10.0% vs. 9.4%), and significantly higher HDL-cholesterol levels (37.9 vs. 32.4 mg/dL; P < 0.0001). Patients with persistently elevated triglyceride levels (n = 34), on three measurements, had a younger age; lower body mass index, HbA1c, and HDL-cholesterol levels; more frequent use of fibrates and insulin; and a higher prevalence of major cardiovascular events. Conclusions: Severe hypertriglyceridemia is a frequent condition in outpatients with T2D participating in the AMD Annals Initiative, and it is associated with male sex, young age, short disease duration, and a worse glycemic profile. Among patients with persistent severe hypertriglyceridemia, hidden FCS may be present.

Association of Fibrate use with clinical expression of hypertrophic cardiomyopathy.

An association between obesity, metabolic abnormalities and clinical hypertrophic cardiomyopathy (HCM) expression has been reported. We investigated whether managing dyslipidaemia with fibrates could affect the clinical expression of HCM. We screened patients who used fibrates between 2010 and 2017 from a nationwide database. After excluding patients with a history of HCM, we identified fibrate-user group (n=412823). We then constructed a 1:1 matched cohort of fibrate-naïve participants (n=412823). After a 1year lag period, we identified the incident HCM cases for the following 5years. During a median follow-up period of 3.96years, we identified 454 incident clinical HCM cases. After adjusting for covariates, fibrate use was associated with a lower risk of clinical HCM expression [hazard ratio (HR) 95% confidence interval (CI): 0.763 (0.630-0.924)]. In subgroup analyses, fibrate use was associated with a reduced risk of clinical HCM expression in patients with a body mass index ≥25kg/m2 and those with abdominal obesity [HR (95% CI): 0.719 (0.553-0.934) and 0.655 (0.492-0.872)], but not in those without obesity. Fibrate use was also associated with lower risks of incident clinical HCM in patients with triglyceride levels ≥150mg/dL and those with metabolic syndrome [HR (95% CI): 0.741 (0.591-0.929) and 0.750 (0.609-0.923)], but not in their counterparts. Regarding lifestyle behaviours, fibrate use appeared to provide more prognostic benefits in patients who currently smoked, consumed alcohol or did not engage in regular physical activities. The use of fibrates is associated with a lower incidence of clinical HCM expression. This association was also more prominent in those with obesity, unhealthy metabolic profiles and poor lifestyle behaviours.

Association of remnant cholesterol with risk of dementia: a nationwide population-based cohort study in South Korea

The association between remnant cholesterol (remnant-C) and cardiovascular disease risk is well established, but its association with dementia remains unclear. We aimed to examine this association using a large-scale population dataset. We did a nationwide, population-based cohort study in which we identified participants aged 40 years and older who underwent the national health examination in 2009 from South Korea's National Health Insurance Service. We excluded people who were younger than 40 years and those with a triglyceride concentration of 400 mg/dL or higher due to concerns regarding the accuracy of calculated low-density lipoprotein cholesterol concentration in individuals with extremely high triglyceride concentrations. People who were previously diagnosed with dementia before the index date, and those who had any missing variables were also excluded. To minimise the influence of possible reverse causation, we excluded individuals who had developed any type of dementia within 1 year of the baseline measurements. We calculated hazard ratios (HRs) for all-cause dementia, Alzheimer's disease, and vascular dementia in each quartile of remnant-C using the Cox proportional hazards model adjusted for age, sex, body-mass index, estimated glomerular filtration rate, income level, smoking status, alcohol consumption, regular exercise, diabetes, hypertension, statin and fibrate use, and total cholesterol concentrations. We also did subgroup analyses to investigate the association between remnant-C and the risk of dementia stratified by age, sex, obesity, glycaemic status (normoglycaemia, impaired fasting glucose, new-onset type 2 diabetes, type 2 diabetes with a duration of less than 5 years, and type 2 diabetes with a duration of 5 years or more), hypertension, chronic kidney disease, and dyslipidaemia, using likelihood ratio tests. 4 234 415 individuals who underwent the national health examination in 2009 were deemed eligible for inclusion. We excluded 1 612 819 individuals on the basis of age, triglyceride concentration, missing variables, or having dementia at baseline. We identified 2 621 596 participants aged 40 years and older (1 305 556 men and 1 316 040 women) who underwent the national health examination and followed them up until the date of any incident of dementia or the end of the study period of Dec 31, 2020. During a median follow-up of 10·3 years (IQR 10·1-10·6), 146 991 (5·6%) participants developed all-cause dementia, 117 739 (4·5%) developed Alzheimer's disease, and 14 536 (0·6%) developed vascular dementia. The risk of dementia increased progressively with higher remnant-C concentrations. Compared with the lowest quartile of remnant-C (quartile 1), HRs in the highest quartile (quartile 4) were 1·11 (95% CI 1·09-1·13) for all-cause dementia, 1·11 (1·08-1·13) for Alzheimer's disease, and 1·15 (1·09-1·21) for vascular dementia. Subgroup analyses revealed that the risk of dementia associated with high remnant-C concentrations was higher in middle-aged people aged 40-59 years than in older people. The risk of dementia associated with high concentrations of remnant-C was notably more pronounced in individuals with diabetes compared with those without diabetes, and the risk increased steeply with a longer duration of diabetes. Results showed that higher remnant-C concentrations were independently associated with increased risks of all-cause dementia, Alzheimer's disease, and vascular dementia. More research is needed to determine the mechanisms underlying this finding. Monitoring and managing higher concentrations of remnant-C might have important implications for reducing the risk of dementia. None.

Fibrates and risk of congenital malformations: a nationwide cohort study in South Korea

PurposeTo examine the association between maternal prescriptions for fibrates and congenital malformations in live births.MethodsNationwide retrospective cohort study was conducted using the data sourced from the Korean National Health Insurance database. A cohort of 756,877 completed pregnancies linked to live-born infants in 215,600 women with dyslipidemia between 2012 and 2021. The study compared data on congenital anomalies between pregnancies who were exposed to fibrates and those who were not exposed to fibrates in the first trimester. Odds ratios (OR) were calculated by a multivariable analyses using logistic regression models to adjust for potential confounders.Results260 pregnancies (0.12%) were exposed to fibrates during the first trimester. The prevalence of malformations in exposed offspirng was 10.77%, not significantly different compared with 9.68% in offspring of women who were not prescribed fibrates during pregnancy in patients with dyslipidemia (OR 1.13; 95% CI 0.75–1.70).ConclusionThis study implies that the use of fibrates during pregnancy may be safe, as it did not show any association with congenital anomalies. However, caution is warranted due to an elevated risk associated with prolonged exposure.

Predictive factors for decompensating events in patients with cirrhosis with primary biliary cholangitis under different lines of therapy.

The landscape in primary biliary cholangitis (PBC) has changed with the advent of second-line treatments. However, the use of obeticholic acid (OCA) and fibrates in PBC-related cirrhosis is challenging. We assessed the impact of receiving a second-line therapy as a risk factor for decompensated cirrhosis in a real-world population with cirrhosis and PBC, and identify the predictive factors for decompensated cirrhosis in these patients. Multicenter study enrolling 388 patients with PBC-cirrhosis from the Spanish ColHai registry. Biopsy (20%), ultrasound (59%), or transient elastography (21%) defined cirrhosis, and the presence of varices and splenomegaly defined clinically significant portal hypertension (CSPH). Paris-II and PBC OCA international study of efficacy criteria determined the response to ursodeoxycholic acid (UDCA), fibrates (n=93), and OCA (n=104). The incidence of decompensated cirrhosis decreased for UDCA versus OCA or fibrates in the real-world population, but they were similar considering the propensity score-matched cohort (UDCA 3.77 vs. second-line therapy 4.5 100 persons-year, respectively), as patients on second-line therapy exhibited advanced liver disease. Consequently, GGT, albumin, platelets, clinically significant portal hypertension, and UDCA response were associated with a decompensating event. OCA response (achieved in 52% of patients) was associated with bilirubin (OR 0.21 [95% CI: 0.06-0.73]) and AST (OR 0.97 [95% CI: 0.95-0.99]), while fibrate response (achieved in 55% of patients) with AST [OR 0.96 (95% CI: 0.95-0.98]). In patients treated with OCA, drug response (sHR 0.23 [95% CI: 0.08-0.64]), diabetes (sHR 5.62 [95% CI: 2.02-15.68]), albumin (sHR 0.34 [95% CI: 0.13-0.89]), and platelets (sHR 0.99 [95% CI: 0.98-1.00]) were related to decompensation. In patients treated with fibrate, drug response (sHR 0.36 (95% CI: 0.14-0.95]), albumin (sHR 0.36 (95% CI: 0.16-0.81]), and clinically significant portal hypertension (sHR 3.70 (95% CI: 1.17-11.70]) were associated with decompensated cirrhosis. Advanced PBC, rather than OCA and fibrates, was found to be associated with decompensating events. Therefore, biochemical and clinical variables should be considered when making decisions about the management of these drugs. Moreover, a positive response to OCA and fibrates reduced the risk of decompensation.

Fibrate and the risk of cardiovascular disease among moderate chronic kidney disease patients with primary hypertriglyceridemia.

Hypertriglyceridemia is the most prevalent dyslipidemia in patients with chronic kidney disease (CKD). However, research about fibrate treatment in CKD patients is limited, and assessing its benefits becomes challenging due to the frequent concurrent use of statins. Thus, this study is aimed to investigate the role of fibrate in CKD stage 3 patients with hypertriglyceridemia who did not receive other lipid-lowering agents. This study enrolled patients newly diagnosed CKD3 with LDL-C<100mg/dL and had never received statin or other lipid-lowering agents from Chang Gung Research Database. The participants were categorized into 2 groups based on the use of fibrate: fibrate group and non-fibrate group (triglyceride >200mg/dL but not receiving fibrate treatment). The inverse probability of treatment weighting was performed to balance baseline characteristics. Compared with the non-fibrate group (n=2020), the fibrate group (n=705) exhibited significantly lower risks of major adverse cardiac and cerebrovascular events (MACCEs) (10.4% vs. 12.8%, hazard ratios [HRs]: 0.69, 95% confidence interval [CI]: 0.50 to 0.95), AMI (2.3% vs. 3.9%, HR: 0.52, 95% CI: 0.37 to 0.73), and ischemic stroke (6.3% vs. 8.0%, HR: 0.67, 95% CI: 0.52 to 0.85). The risk of all-cause mortality (5.1% vs. 4.5%, HR: 1.09, 95% CI: 0.67 to 1.79) and death from CV (2.8% vs. 2.3%, HR: 1.07, 95% CI: 0.29 to 2.33) did not significantly differ between the 2 groups. This study suggests that, in moderate CKD patients with hypertriglyceridemia but LDL-C < 100mg/dL who did not take other lipid-lowering agents, fibrates may be beneficial in reducing cardiovascular events.

Time-to-onset Analysis of Rhabdomyolysis due to Different Proton Pump Inhibitors Using a Pharmacovigilance Database.

Recent research has increasingly demonstrated an association between proton pump inhibitors (PPIs) and serious adverse events. This study aimed to evaluate the association between PPI and rhabdomyolysis (RM), examining its time-to-onset profiles using the Japanese Adverse Drug Event Report (JADER) database. Data spanning from April 2004 to March 2022 were used. The association between PPIs and RM was evaluated using the reporting odds ratio (ROR), adjusted for sex and age. Subsequent analyses were conducted after excluding cases involving concomitant use of statins or fibrates. Furthermore, the onset time of RM and Weibull distribution parameters were calculated to evaluate the expression profile of RM, and the outcomes were examined. RM was associated with the use of esomeprazole, omeprazole, and rabeprazole, even in the absence of concomitant statin or fibrate use. The median time to RM onset varied among PPIs, ranging from 6.5 to 127 d. The Weibull distribution parameters indicated that the hazard types of nearly all orally administered PPIs were classified as early failure or close to random failure. Regarding outcomes, cases of death were reported for all PPIs except vonoprazan. The findings suggest the need for vigilant monitoring of RM during PPI administration, particularly in the early stages, considering the varying onset times.

Can Concurrent Fibrate Use Reduce Cardiovascular Risks among Moderate Chronic Kidney Disease Patients Undergoing Statin Therapy? A Cohort Study.

The role of fibrates in treating hypertriglyceridemia in chronic kidney disease (CKD) patients to prevent cardiovascular disease (CVD) has been insufficiently investigated. Since statin is considered the first-line treatment for dyslipidemia in CKD patients, this study aims to evaluate the role of concurrent fibrate therapy with statins among moderate CKD patients. We recruited CKD3 patients from the Chang Gung Research Database who were receiving statin treatment but had not previously been administered ezetimibe or niacin. The participants were divided into two groups based on their use of fibrates (fibrate group) or those with triglyceride levels >200 mg/dL without fibrate treatment (non-fibrate group). The fibrate group (n = 954) only exhibited a significantly lower incidence of AMI (4.4% vs. 5.4%, HR: 0.77, 95% CI: 0.61 to 0.98). The risk of major adverse cardiovascular and cerebrovascular events (14.7% vs. 15.6%, HR: 0.91, 95% CI: 0.72 to 1.15) and all-cause mortality (5.7% vs. 6.1%, HR: 0.91, 95% CI: 0.63 to 1.30) did not significantly differ between the fibrate group and the non-fibrate group (n = 2358). In moderate CKD patients, combining fibrate therapy with statins may not offer additional cardiovascular protection compared to statin alone.

Fibrates and the risk of cardiovascular outcomes in chronic kidney disease patients.

The high risk of major adverse cardiovascular events (MACE) in patients with chronic kidney disease (CKD) has been well described. However, the efficacy of fibrates on the risk of MACE in patients with CKD remains unclear. We conducted a nested case-control study using data from a large administrative database that included more than 1.5 million Japanese patients. We defined cases as CKD patients with incidences of MACE and matched them with controls based on age, sex, calendar year of cohort entry and CKD stage. Fibrate exposure timing was categorized as current, recent or past. A conditional logistic regression analysis was used to investigate the association between fibrate use and the risk of MACE. Our study included 47 490 patients with CKD, with 15 830 MACE identified during a median follow-up of 9.4 months. The numbers of fibrates used during the study period were 556 (3.5%) in the case group and 1109 (3.5%) in the control group. Fibrate use was significantly associated with a decreased risk of MACE [odds ratio (OR) 0.84; 95% confidence interval (CI) 0.75-0.94], particularly for current (OR 0.81; 95% CI 0.68-0.97) and recent use (OR 0.65; 95% CI 0.48-0.90). Regarding the class effect of fibrates, pemafibrate use, but not bezafibrate or fenofibrate use, was significantly associated with a decreased risk of MACE (OR 0.73; 95% CI 0.528-0.997). Recent and current fibrate use, especially pemafibrate use, was associated with a reduced risk of MACE in patients with CKD. This suggests the potential benefits of continuous fibrate therapy and the possible superiority of pemafibrate over other fibrates. However, further investigations in different populations are required to confirm the generalizability of these findings.

Effect of Lipids on Diabetic Retinopathy in a Large Cohort of Diabetic Patients after 10 Years of Follow-Up.

(1) Background: Diabetic retinopathy (DR) remains the leading cause of low vision and blindness in young adults of working age. Although the most important risk factors-such as the duration of diabetes mellitus (DM) and glycemic control measured by HbA1c-are known, the effects of lipids are not as clear. The aim of the present study is to analyze the effects of lipids on the development of DR. (2) Methods: This is a retrospective study of a population of 175,645 DM2 patients, during the period 2010 to 2020, in which the effects of different lipid factors are studied. (3) Results: The variables that most influenced the development of DR in our study, based on significance and cumulative hazard (CH), were arterial hypertension (CH 1.217, p < 0.001), HbA1c levels (CH 1.162, p = 0.001), microalbuminuria (CH 1.012, p < 0.001), LDL-C cholesterol (CH 1.007, p = 0.012), TC/HDL-C index (CH 1.092, p < 0.001), No-HDL-C/HDL-C index (CH 1.065, p = 0.002), the use of statins (CH 1.001, p = 0.005), and body mass index (CH 1.007, p < 0.001). (4) Conclusions: LDL-cholesterol, TC/HDL-C, and No-HDL-C/HDL-C indices are related to the development of DR, and there is a protective effect of HDL-cholesterol and the use of fibrates.

Development and application of pharmacological statin-associated muscle symptoms phenotyping algorithms using structured and unstructured electronic health records data.

Statins are widely prescribed cholesterol-lowering medications in the United States, but their clinical benefits can be diminished by statin-associated muscle symptoms (SAMS), leading to discontinuation. In this study, we aimed to develop and validate a pharmacological SAMS clinical phenotyping algorithm using electronic health records (EHRs) data from Minnesota Fairview. We retrieved structured and unstructured EHR data of statin users and manually ascertained a gold standard set of SAMS cases and controls using the published SAMS-Clinical Index tool from clinical notes in 200 patients. We developed machine learning algorithms and rule-based algorithms that incorporated various criteria, including ICD codes, statin allergy, creatine kinase elevation, and keyword mentions in clinical notes. We applied the best-performing algorithm to the statin cohort to identify SAMS. We identified 16 889 patients who started statins in the Fairview EHR system from 2010 to 2020. The combined rule-based (CRB) algorithm, which utilized both clinical notes and structured data criteria, achieved similar performance compared to machine learning algorithms with a precision of 0.85, recall of 0.71, and F1 score of 0.77 against the gold standard set. Applying the CRB algorithm to the statin cohort, we identified the pharmacological SAMS prevalence to be 1.9% and selective risk factors which included female gender, coronary artery disease, hypothyroidism, and use of immunosuppressants or fibrates. Our study developed and validated a simple pharmacological SAMS phenotyping algorithm that can be used to create SAMS case/control cohort to enable further analysis which can lead to the development of a SAMS risk prediction model.

Recent Advances in Adjuvant Pharmacotherapy for Neonatal Indirect Hyperbilirubinemia: A Narrative Review

Context: Hyperbilirubinemia is a common cause for diagnostic work-up and therapeutic intervention in neonates and needs a convenient, quick, and safe treatment modality. Phototherapy is the most common treatment for neonatal jaundice; however, complementary treatment is still needed. Despite the identification of the enzymatic pathways of bilirubin catabolism, few pharmacological interventions have been found to be effective in reducing bilirubin, along with traditional phototherapy. This review was conducted to evaluate recent pharmacotherapies as adjuvants to phototherapy for the treatment of neonatal indirect hyperbilirubinemia (IHB). Evidence Acquisition: This study was carried out through a literature search with the keywords of Infant, Newborn, and Indirect Hyperbilirubinemia, combined with Drug Therapy, in PubMed, Scopus, International Statistical Institute, Web of Science, Cochrane, and Embase databases. This study included relevant articles (i.e., randomized controlled trials, observational studies, guidelines, and reviews) written in English and published between 2012 - 2022. Results: This narrative review first assessed the relevant articles to define IHB and its etiology. Then, the efficacy and side effects of recent pharmacologic agents as adjuvants to phototherapy were discussed. Additionally, this study reviewed the efficacy and safety of drugs prescribed to neonates to prevent jaundice. Conclusions: The best drug for adjuvant pharmacotherapy, in addition to phototherapy, for neonatal jaundice has not still been identified. The use of probiotics, prebiotics, synbiotics, and ursodeoxycholic acid (UDCA) in adjuvant to phototherapy has been recently increasing, and beneficial results were observed in most studies. The use of agar, charcoal, fibrate, and phenobarbital had a minor therapeutic role in recent years. There were conflicting results about the efficacy of herbal agents in neonatal jaundice. The use of intravenous immunoglobulin (IVIG), metalloporphyrin, and albumin is also limited to severe or immune-related IHB cases. The prescription of the aforementioned drugs sometimes had different results. Therefore, further research in this regard is necessary.

Confirmation of Statin and Fibrate Use from Small-Volume Archived Plasma Samples by High-Throughput LC-MS/MS Method.

Designing studies for lipid-metabolism-related biomarker discovery is challenging because of the high prevalence of various statin and fibrate usage for lipid-lowering therapies. When the statin and fibrate use is determined based on self-reports, patient adherence to the prescribed statin dose regimen remains unknown. A potentially more accurate way to verify a patient's medication adherence is by direct analytical measurements. Current analytical methods are prohibitive because of the limited panel of drugs per test and large sample volume requirement that is not available from archived samples. A 4-min-long method was developed for the detection of seven statins and three fibrates using 10 µL of plasma analyzed via reverse-phase liquid chromatography and tandem mass spectrometry. The method was applied to the analysis of 941 archived plasma samples collected from patients before cardiac catheterization. When statin use was self-reported, statins were detected in 78.6% of the samples. In the case of self-reported atorvastatin use, the agreement with detection was 90.2%. However, when no statin use was reported, 42.4% of the samples had detectable levels of statins, with a similar range of concentrations as the samples from the self-reported statin users. The method is highly applicable in population studies designed for biomarker discovery or diet and lifestyle intervention studies, where the accuracy of statin or fibrate use may strongly affect the statistical evaluation of the biomarker data.

Association of lipid-lowering agent use and dry eye disease: A nationwide matched case-control study in Taiwan, 2002-2016.

The purpose of this study is to evaluate the association between lipid-lowering agent use and the risks of diagnosed dry eye disease (DED). 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. 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. 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.

Pemafibrate inhibited renal dysfunction and fibrosis in a mouse model of adenine-induced chronic kidney disease

AimsPeroxisome proliferator-activated receptor-alpha (PPARα) levels are markedly lower in the kidneys of chronic kidney disease (CKD) patients. Fibrates (PPARα agonists) are therapeutic agents against hypertriglyceridemia and potentially against CKD. However, conventional fibrates are eliminated by renal excretion, limiting their use in patients with impaired renal function. Here, we aimed to evaluate the renal risks associated with conventional fibrates via clinical database analysis and investigate the renoprotective effects of pemafibrate, a novel selective PPARα modulator mainly excreted into the bile. Main methodsThe risks associated with conventional fibrates (fenofibrate, bezafibrate) to the kidneys were evaluated using the Food and Drug Administration Adverse Event Reporting System. Pemafibrate (1 or 0.3 mg/kg/day) was administered daily using an oral sonde. Its renoprotective effects were examined in unilateral ureteral obstruction (UUO)-induced renal fibrosis model mice (UUO mice) and adenine-induced CKD model mice (CKD mice). Key findingsThe ratios of glomerular filtration rate decreased and blood creatinine increased were markedly higher after conventional fibrate use. Pemafibrate administration suppressed increased gene expressions of collagen-I, fibronectin, and interleukin 1 beta (IL-1β) in the kidneys of UUO mice. In CKD mice, it suppressed increased plasma creatinine and blood urea nitrogen levels and decreased red blood cell count, hemoglobin, and hematocrit levels, along with renal fibrosis. Moreover, it inhibited the upregulation of monocyte chemoattractant protein-1, IL-1β, tumor necrosis factor-alpha, and IL-6 in the kidneys of CKD mice. SignificanceThese results demonstrated the renoprotective effects of pemafibrate in CKD mice, confirming its potential as a therapeutic agent for renal disorders.
