Abstract
BACKGROUND Statins have beneficial effects on intrahepatic circulation and decrease portal hypertension and rifaximin modulates the gut microbiome and might prevent bacterial translocation in patients with cirrhosis. Therefore, this drug combination might be of therapeutic benefit in patients with decompensated cirrhosis. However, there is concern regarding the safety of statins in patients with decompensated cirrhosis. We assessed the safety of two different doses of simvastatin, in combination with rifaximin, in patients with decompensated cirrhosis. METHODS We did a double-blind, randomised, placebo-controlled, phase 2 trial in patients with decompensated cirrhosis and moderate-to-severe liver failure from nine university hospitals in six European countries (Italy, France, Holland, Germany, the UK, and Spain). Patients older than 18 years with Child-Pugh class B or C disease were eligible. We randomly assigned patients (1:1:1) to receive either simvastatin 40 mg/day plus rifaximin 1200 mg/day, simvastatin 20 mg/day plus rifaximin 1200 mg/day, or placebo of both medications for 12 weeks. Randomisation was stratified according to Child-Pugh class (B vs C) and restricted using blocks of multiples of three. The primary endpoint was development of liver or muscle toxicity, as defined by changes in liver aminotransferases (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]), alkaline phosphastase, and creatine kinase. The study is registered with the European Union Clinical Trials Register, 2016-004499-23, and with ClinicalTrials.gov, NCT03150459. FINDINGS The study recruitment period was between July 28, 2017, and Jan 2, 2018. Follow-up finished on March 12, 2018. 50 patients were randomly assigned to simvastatin 40 mg/day plus rifaximin 1200 mg/day (n=18), simvastatin 20 mg/day plus rifaximin 1200 mg/day (n=16), or placebo of both medications (n=16). Six patients (two from each group) were excluded. Therefore, the full analysis set included 44 patients (16 in the simvastatin 40 mg/day plus rifaximin 1200 mg/day group, 14 in the simvastatin 20 mg/day plus rifaximin mg/day group, and 14 in the placebo group). After a safety analyses when the first ten patients completed treatment, treatment was stopped prematurely in the simvastatin 40 mg/day plus rifaximin group due to recommendations by the data safety monitoring board. Patients in the simvastatin 40 mg/day plus rifaximin group showed a significant increase in AST and ALT compared with the placebo group (mean differences between the groups at the end of treatment for AST 130 IU/L [95% CI 54 to 205; p=0·0009] and for ALT 61 IU/L [22 to 100; p=0·0025]. We observed no significant differences at 12 weeks in AST and ALT between the simvastatin 20 mg/day plus rifaximin and placebo group (for AST -14 IU/L [-91 to 64; p=0·728] and for ALT -8 IU/L [-49 to 33; p=0·698]). We observed no significant differences in alkaline phosphatase between the the simvastatin 40 mg/day plus rifaximin or the simvastatin 20 mg/day plus rifaximin groups compared with placebo. Patients in the simvastatin 40 mg/day plus rifaximin group showed an increase in creatine kinase at the end of treatment compared with patients in the placebo group (1009 IU/L [208 to 1809]; p=0·014). We observed no significant changes in creatine kinase in the simvastatin 20 mg/day plus rifaximin group (4·2 IU/L [-804 to 813]; p=0·992). Three (19%) patients in the simvastatin 40 mg/day group developed liver and muscle toxicity consistent with rhabdomyolysis. The number of patients who stopped treatment because of adverse events was significantly higher in the simvastatin 40 mg/day plus rifaximin group (nine [56%] of 16 patients) compared with the other two groups (two [14%] of 14 for both groups; p=0·017). There were no serious unexpected adverse reactions reported during the study. INTERPRETATION Treatment with simvastatin 40 mg/day plus rifaximin in patients with decompensated cirrhosis was associated with a significant increase in adverse events requiring treatment withdrawal, particularly rhabdomyolysis, compared with simvastatin 20 mg/day plus rifaximin. We recommend simvastatin 20 mg/day as the dose to be used in studies investigating the role of statins in patients with decompensated cirrhosis. FUNDING Horizon 20/20 European programme.

Abstract
OBJECTIVE To study whether the changes in bioequivalent drugs with different appearances are associated with an increase in lack of adherence and medication use errors, in patients >65years old treated with antihypertensive and lipid-lowering medications. DESIGN Observational longitudinal prospective cohort study with a one-year follow-up period between 1 January 2013 and 31 December 2014. LOCATION Primary Healthcare Centres in the Community of Madrid. PARTICIPANTS Patients ≥65years-old with a diagnosis of hypertension and/or dyslipidaemia receiving treatment with Enalapril and/or Amlodipine and/or Simvastatin. MAIN MEASUREMENTS Variables collected during a Primary Care consultation by means of a personal interview were: sociodemographic (age, gender, level of education), clinical variables, adherence (Morisky-Green test and direct counting), medication errors (number and type), medication changes and number, analytical (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides) and combined variable (error and/or adherence). There were 1 baseline and 4 quarterly visits. RESULTS The study included 274 patients with a mean age 72 (6.6) years, of whom 47.8% were female. Some medication changes were observed in 134 patients (48.9%), with a median of 3 (IQR 1-5) and a maximum of 11 changes. The risk of presenting with a medication use error or decreased adherence was increased in patients exposed to changes in all visits with RR 1.14 (1.16-1.69) at one year of follow-up. The most frequent error was the loss of dose. For each change in medication, the probability of a combined event increases by 41%. CONCLUSIONS The changes made in bioequivalent drugs with different appearance could increase the number of medication use errors and decrease the adherence. More studies should be carried out to assess how much this affects the control of the disease. The intervention section is not considered because it is an observational study.

Abstract
BACKGROUND The relevance of the IMPROVE-IT trial on real-life practice has not been explored in patients with ACS. METHODS A prospective Swiss cohort of 6266 patients hospitalized for ACS between 2009 and 2017 with a one-year follow-up. The primary endpoints were the ezetimibe use overall or in combination with high-intensity statin at discharge and at one year after ACS. Secondary endpoint was LDL-C target achievement at one year in a subsample of 2984 patients. Relative Ratios (RR) were used to assess changes in primary endpoints before and after the publication of IMPROVE-IT, adjusting for age, sex, diabetes, prior myocardial infarction, LDL-C and attendance to cardiac rehabilitation. RESULTS The period following the publication of the IMPROVE-IT trial was associated with a steady increase in the use of ezetimibe at discharge (from 1.8% to 3.8%, P < 0.001, adjusted RR 2.85, 95% CI 1.90-4.25) and at one year (from 5.0% to 13.8%, P < 0.001, adjusted RR 3.00, 95% CI 2.40-3.75). The combination of high-intensity statin and ezetimibe rose from 0.9% to 2.1% at discharge (P < 0.001, adjusted RR 3.35, 95% CI 1.90-5.89) and from 2.1% to 7.8% at one year (P < 0.001, adjusted RR 3.98, 95% CI 2.90-5.47). The period following the publication of the IMPROVE-IT trial was associated with an improvement of LDL-C target <1.8 mmol/L (adjusted RR 1.37, 95% CI 1.12-1.68). CONCLUSIONS After the publication of the IMPROVE-IT trial, the use of ezetimibe was increased by three-fold in a large contemporary cohort of ACS patients, concomitant with an improved LDL-C target achievement.

Abstract
OBJECTIVE To conduct a randomized double-blind prospective study to investigate effect of different doses of atorvastatin, rosuvastatin, and simvastatin on elderly patients with ST-elevation AMI after PCI. METHODS One hundred and ninety-two AMI patients over 60 years old who underwent PCI were randomly divided into six groups: the low atorvastatin group, high atorvastatin group; low rosuvastatin group; high rosuvastatin group; low simvastatin group; high simvastatin group. Demographic data and clinical information as well as coronary angiography parameters were recorded. Plasma levels of CK-MB, BNP, ALT, and TnI were measured at 12 hr, 24 hr, and 1 week after PCI. Major cardiovascular events (MACE) were recorded and analyzed using Kaplan-Meier (K-M) curve. RESULTS No significant differences were observed in angiographic and procedural characteristics. In all high dose groups, all levels of CK-MB, BNP, ALT, and TnI were significantly lower. However, after 1 week of PCI, only CK-MB, BNP, and TnI showed significant difference between high and low dose groups. Patients in high dose groups had significantly lower rates for surgical or percutaneous intervention, recurrence of angina, and rehospitalization. K-M curve analysis also showed cumulative incidence freedom time of overall MACE in high dose groups was significantly longer. No significant differences were found among different drugs with the same doses. CONCLUSION Patients with higher doses had lower level of CK-MB, BNP, ALT, and TnI and lower occurrence of MACE after PCI.

Abstract
INTRODUCTION Beta-blockers are the mainstay agents for portal pressure reduction and to modestly reduce hepatic venous pressure gradient (HVPG). We studied whether addition of simvastatin to carvedilol in cirrhotic patients for primary prophylaxis improves the hemodynamic response. METHODS Cirrhotic patients with esophageal varices and with baseline HVPG > 12 mm Hg were prospectively randomized for primary prophylaxis to receive either carvedilol (group A, n = 110) or carvedilol plus simvastatin (group B, n = 110). Primary objective was to compare hemodynamic response (HVPG reduction of ≥20% or <12 mm Hg) at 3 months, and secondary objectives were to compare first bleed episodes, death, and adverse events. RESULTS The groups were comparable at baseline. The proportion of patients achieving HVPG response at 3 months was comparable between groups (group A-36/62 [58.1%], group B-36/59 [61%], P = 0.85). The degree of mean HVPG reduction (17.3% and 17.8%, respectively, P = 0.98) and hemodynamic response (odds ratio [OR]: 0.88; 95% confidence interval [CI]: 0.43-1.83, P = 0.74) was also not different between the groups. Patients who achieved target heart rate with no hypotensive episodes in either group showed better hemodynamic response (77.8% vs 59.2%, P = 0.04). Failure to achieve target heart rate (OR: 0.48; 95% CI: 0.22-1.06) and Child C cirrhosis (OR: 4.49; 95% CI: 1.20-16.8) predicted nonresponse. Three (3.7%) patients on simvastatin developed transient transaminitis and elevated creatine phosphokinase and improved with drug withdrawal. Two patients in each group bled (P = 0.99). Three patients and 1 patient, respectively, in group A and B died (P = 0.32), with sepsis being the cause of death. DISCUSSION Addition of simvastatin to carvedilol for 3 months for primary prophylaxis of variceal bleeding does not improve hemodynamic response over carvedilol monotherapy. Simvastatin usage should be closely monitored for adverse effects in Child C cirrhotic patients.

Liu, N, Yang, G, Liu, Y, Hu, M, Cai, Y, Hu, Z, Jia, C, Zhang, M
Journal of cardiovascular pharmacology. 2020;(2):168-173
Abstract
BACKGROUND Identifying patients with high risk of low response to statin therapy is important for optimization of lipid-lowering therapy. Cholesterol 7α-hydroxylase, a rate-limiting enzyme encoded by cytochrome P450 7A1 (CYP7A1) gene, is considered to be associated with statin efficacy. This study aimed to investigate the association between a novel CYP7A1 single nucleotide polymorphism rs3824260 and statin treatment response for hypercholesteremic patients in Chinese Han population. METHODS A total of 336 subjects were prescribed with simvastatin for 12 weeks after enrollment. Plasma lipid parameters were measured at enrollment and after 12-week simvastatin treatment separately. Subjects were classified into high- and low-response groups depending on their total cholesterol, low-density lipoprotein cholesterol (LDL-C) and TG changes and increase or reduction groups according to their high-density lipoprotein cholesterol (HDL-C) levels changing after simvastatin treatment. The CYP7A1 rs3824260 was genotyped from blood samples with a SNaPshot assay. RESULTS At baseline, the LDL-C level and TG level were significantly higher in the AA genotype, while the HDL-C level was significantly higher in the GG genotype of CYP7A1 rs3824260. Patients carrying AA genotype are at an increased risk of low response for LDL-C reduction (odds ratio = 2.295, 95% confidence interval = 1.164-4.524, P = 0.016). Furthermore, the GG genotype of rs3824260 was significantly associated with a high risk of HDL-C reduction response after simvastatin therapy (odds ratio = 2.240, 95% confidence interval = 1.137-4.413, P = 0.025). CONCLUSIONS The CYP7A1 gene polymorphism rs3824260 is related to inappropriate response of simvastatin treatment for hypercholesterolemia patients in Chinese Han population.

Clinical therapeutics. 2020;(2):e13-e31
Abstract
PURPOSE Chronic inflammation increases the risks for cardiovascular disease, type 2 diabetes, and cancer. Recently, the antiinflammatory effects of statins, as cholesterol-lowering medications, have been considered. This study systematically reviewed and summarized earlier findings from randomized clinical trials about the effects of statins on serum concentrations of C-reactive protein (CRP) and interleukin (IL)-6 in patients with abnormal glucose homeostasis. METHODS Relevant articles published through October 2019 were searched using suitable key words on the PubMed/MEDLINE, SCOPUS, EMBASE, and Google Scholar databases. RCTs were included if they compared the effects of statins on serum concentrations of CRP and IL-6 in adults with abnormal glucose homeostasis. The effect sizes were represented as weighted mean differences (WMDs) and 95% CI s using a random-effects model. Subgroup analysis was performed to find possible sources of heterogeneity. FINDINGS Overall, 17 publications with 21 effect sizes and which enrolled 3766 subjects (1895 participants in intervention and 1871 in control groups) were included. Combining 13 effect sizes from 10 studies, a significant reduction in serum CRP concentration following the administration of atorvastatin was found (WMD, -0.35; 95% CI, -0.54 to -0.17; I2 = 90.6%). Based on 5 effect sizes from 4 studies, we found a statistically significant reduction in serum IL-6 concentration after atorvastatin therapy (WMD, -0.44; 95% CI, -0.65 to -0.22; I2 = 93.9%). Pooling 6 effect sizes from 5 studies revealed a significantly reduced serum concentration of CRP after simvastatin therapy (WMD, -0.66; 95% CI, -0.79 to -0.54; I2 = 97.6%). IMPLICATIONS The administration of atorvastatin or simvastatin in patients with abnormal glucose hemostasis was associated with a reduced serum CRP concentration. Atorvastatin therapy might also help to decrease serum IL-6 concentration in these patients.

Abstract
Statin-related muscle side effects are a constant healthcare problem since patient compliance is dependent on side effects. Statins reduce plasma cholesterol levels and can prevent secondary cardiovascular diseases. Although statin-induced muscle damage has been studied, preventive or curative therapies are yet to be reported. We exposed primary human muscle cell populations (n = 22) to a lipophilic (simvastatin) and a hydrophilic (rosuvastatin) statin and analyzed their expressome. Data and pathway analyses included GOrilla, Reactome and DAVID. We measured mevalonate intracellularly and analyzed eicosanoid profiles secreted by human muscle cells. Functional assays included proliferation and differentiation quantification. More than 1800 transcripts and 900 proteins were differentially expressed after exposure to statins. Simvastatin had a stronger effect on the expressome than rosuvastatin, but both statins influenced cholesterol biosynthesis, fatty acid metabolism, eicosanoid synthesis, proliferation, and differentiation of human muscle cells. Cultured human muscle cells secreted ω-3 and ω-6 derived eicosanoids and prostaglandins. The ω-6 derived metabolites were found at higher levels secreted from simvastatin-treated primary human muscle cells. Eicosanoids rescued muscle cell differentiation. Our data suggest a new aspect on the role of skeletal muscle in cholesterol metabolism. For clinical practice, the addition of omega-n fatty acids might be suitable to prevent or treat statin-myopathy.

Biochemical and biophysical research communications. 2019;(4):772-779
Abstract
The changes in cellular metabolism play an important role in promoting tumor progression. Recent findings suggested that the mutation of tumor suppressor gene p53 promoted lipids synthesis and mutant p53 (mutp53) was essential for regulating mevalonate pathway for cholesterol synthesis. Simvastatin, a 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitor, was found to exhibit therapeutic effects against many types of cancers including breast cancer, colon cancer, lung cancer, etc. However, the underlying mechanism of the antitumor effect of simvastatin still needs to be further investigated. Our data demonstrated that suppression of mevalonate pathway by simvastatin significantly upregulated Kruppel-like factor 2 (KLF2) and p21WAF1/CIP1 expression in mutp53 colon cancer cells SW1116 but not in p53 wild type cells HCT116. Meanwhile, we found that overexpression of KLF2 could significantly induce p21WAF1/CIP1 expression, inhibit Wnt signaling and suppress epithelial-mesenchymal transition, indicating that KL2 might mediate antitumor effect of simvastatin in SW1116 cells. Moreover, bioinformatic analysis from The Cancer Genome Atlas (TCGA) database indicated that KLF2 were positively correlated with CDKN1A (encoding p21WAF1/CIP1), both of which were downregulated in colon cancer tissue, especially in p53 mutant colon cancer tissue. The results showed that KLF2 might be a tumor suppressor gene in colon cancer, which was in accordance with our experimental data. We also found that CDKN1A expression in mutant p53 colon cancer tissue was significant decreased when compared with p53 wild type colon cancer tissue, while Wnt ligand Wnt5a exhibited the highest level in p53 mutant colon cancer tissue. These data provide strong evidences for clinical application of simvastatin in treatment of colon cancer with p53 mutation.

Statin Treatment Decreases Mitochondrial Respiration But Muscle Coenzyme Q10 Levels Are Unaltered: The LIFESTAT Study.
Dohlmann, TL, Morville, T, Kuhlman, AB, Chrøis, KM, Helge, JW, Dela, F, Larsen, S
The Journal of clinical endocrinology and metabolism. 2019;(7):2501-2508
Abstract
BACKGROUND Myalgia is a common adverse effect of statin therapy, but the underlying mechanism is unknown. Statins may reduce levels of coenzyme Q10 (CoQ10), which is an essential electron carrier in the mitochondrial electron transport system, thereby impairing mitochondrial respiratory function, potentially leading to myalgia. OBJECTIVES To investigate whether statin-induced myalgia is coupled to reduced intramuscular CoQ10 concentration and impaired mitochondrial respiratory function. METHODS Patients receiving simvastatin (i.e., statin) therapy (n = 64) were recruited, of whom 25 experienced myalgia (myalgic group) and 39 had no symptoms of myalgia (NS group). Another 20 had untreated high blood cholesterol levels (control group). Blood and muscle samples were obtained. Intramuscular CoQ10 concentration was measured, and mitochondrial respiratory function and reactive oxygen species (ROS) production were measured. Citrate synthase (CS) activity was used as a biomarker of mitochondrial content in skeletal muscle. RESULTS Intramuscular CoQ10 concentration was comparable among groups. Mitochondrial complex II-linked respiration was reduced in the statin-myalgic and -NS groups compared with the control group. When mitochondrial respiration was normalized to CS activity, respiration rate was higher in the myalgic group compared with the NS and control groups. Maximal ROS production was similar among groups. CONCLUSION Statin therapy appeared to impair mitochondrial complex-II-linked respiration, but the mitochondrial capacity for complex I+II-linked respiration remained intact. Myalgia was not coupled to reduced intramuscular CoQ10 levels. Intrinsic mitochondrial respiratory capacity was increased with statin-induced myalgia but not accompanied by increased ROS production.
