Abstract Background and aims: Diabetic dyslipidaemia is characterised by very high levels of triglycerides, low high-density lipoprotein (HDL), and slightly elevated low-density lipoprotein (LDL) cholesterol. Additionally, the potentially increased risk of morbidity and mortality following atherosclerotic cardiovascular diseases should be considered in the treatment of dyslipidaemia in patients with diabetes. Methods: We performed a meta-analysis of the published data to compare the effects of statin-ezetimibe combination therapy and statin monotherapy on lipid and glucose parameters in patients with diabetes. Additionally, the safety based on the reported adverse events was compared between the two groups. Results: Seventeen articles were included in this meta-analysis. In the efficacy assessment, the combination treatment afforded a significantly greater reduction in LDL cholesterol than did statin monotherapy (standard difference in means = 0.894; 95% confidence interval 0.598–1.191). A significantly greater improvement effect was observed in the levels of HDL cholesterol, total cholesterol, triglyceride, and apolipoprotein B, but not apolipoprotein A1, with combination therapy than with statin monotherapy. Additionally, combination therapy reduced the fasting blood glucose levels more significantly than did statin monotherapy. In terms of safety, there were no significant differences in treatment-related adverse events between the two treatments. Conclusions: Statin-ezetimibe combination therapy appears to enhance LDL cholesterol and other lipid levels without an increased risk of adverse events, compared with statin monotherapy. The present meta-analysis presents valid evidence for appropriate drug regimens to treat dyslipidaemia in patients with diabetes.

Abstract Context To enable prevention and treatment of age-related macular degeneration(AMD), understanding risk factors for AMD is important. Objective We tested the hypotheses that elevated plasma apolipoprotein A1 and high-density lipoprotein(HDL) cholesterol, and low levels of low-density lipoprotein(LDL) cholesterol, are associated with increased risk of AMD. Design and Setting From the Danish general population, we studied 106,703 and 16,032 individuals in the Copenhagen General Population Study(CGPS) and the Copenhagen City Heart Study(CCHS) with median follow-up of respectively 9 and 32 years. Main Outcome Measures 1,787 AMD in CGPS and 206 in CCHS. Results Higher concentrations of plasma apolipoprotein A1 and HDL cholesterol, and lower concentrations of LDL cholesterol, were associated with higher risk of AMD in CGPS. After multifactorial adjustment, individuals in the highest versus lowest quartile of plasma apolipoprotein A1 and HDL cholesterol had hazard ratios for AMD of 1.40(95%CI:1.20-1.63) and 1.22(1.03-1.45). Corresponding hazard ratios for individuals in the lowest versus highest quartile of LDL cholesterol were 1.18(1.02-1.37). Per 100 mg/dL higher plasma apolipoprotein A1, 1 mmol/L(39 mg/dL) higher HDL, and 1 mmol/L(39mmol/L) lower LDL cholesterol, the hazard ratios for AMD were 1.53(1.31-1.80), 1.19(1.07-1.32), and 1.05(1.00-1.11), respectively, with similar results across strata of different risk factors. Higher concentrations of HDL cholesterol were also associated with higher risk of AMD in the CCHS. Conclusion Elevated plasma apolipoprotein A1 and HDL cholesterol, and lower LDL cholesterol, are associated with increased risk of age-related macular degeneration.

Background: As immune checkpoint inhibitors (ICIs) transition to the forefront of cancer treatment, a better understanding of immune related adverse events (IRAEs) is essential to promote safe clinical practice. Dermatologic adverse events are the most common IRAEs and can lead to drug withdrawal and decreased quality of life. This meta-analysis aimed to investigate the risk of the most prevalent dermatologic adverse events (pruritus and rash) among various ICI treatment regimens.Methods: A systematic search of electronic databases was performed to identify qualified randomized controlled trials (RCTs). Data for any grade and high grade pruritus and rash were extracted for meta-analysis. Two reviewers independently assessed methodological quality. The relative risk summary and 95% confidence interval were calculated.Results: 50 RCTs involving 29941 patients were analyzed. The risk of pruritus (2.15 and 4.21 relative risk respectively) and rash (1.61 and 3.89 relative risk respectively) developing from CTLA-4 or PD-1/-L1 inhibitor were increased compared to placebo, but this effect was not dose-dependent. PD-1/-L1 plus CTLA-4 inhibitor was associated with increased risk of pruritus (1.76 and 0.98 relative risk respectively) and rash (1.72 and 1.37 relative risk respectively) compared to either monotherapy. Compared with CTLA-4 inhibitor, PD-1/-L1 inhibitor had a significantly decreased risk of pruritus and rash in both monotherapy and combination therapy (0.65 and 0.29 relative risk respectively). No significant difference was found between PD-1/-L1 inhibitor combined with chemotherapy and PD-1/-L1 monotherapy in any grade and high grade rash (0.84 and 1.43 relative risk respectively). In subgroup analyses, PD-1 inhibitor was associated with reduced risk of pruritus and rash compared to PD-L1 inhibitor.Conclusion: Our meta-analysis demonstrates a better safety profile for PD-1/-L1 inhibitor compared to CTLA-4 inhibitor in terms of pruritus and rash among both monotherapy and multiple combination therapies. PD-L1 inhibitor may contribute to an increased risk of pruritus and rash compared to PD-1 inhibitor.

Objectives. The aim of this study was to provide the first study to systematically analyze the efficacy and safety of PCSK9-mAbs in the treatment of familial hypercholesterolemia (FH). Methods. A computer was used to search the electronic Cochrane Library, PubMed/MEDLINE, and Embase databases for clinical trials using the following search terms: “AMG 145”, “evolocumab”, “SAR236553/REGN727”, “alirocumab”, “RG7652”, “LY3015014”, “RN316/bococizumab”, “PCSK9”, and “familial hypercholesterolemia” up to November 2020. Study quality was assessed with the Cochrane Collaboration’s tool, and publication bias was evaluated by a contour-enhanced funnel plot and the Harbord modification of the Egger test. After obtaining the data, a meta-analysis was performed using R software, version 4.0.3. Results. A meta-analysis was performed on 7 clinical trials (926 total patients). The results showed that PCSK9-mAbs reduced the LDL-C level by the greatest margin, WMD −49.14%, 95% CI: −55.81 to −42.47%, on FH versus control groups. PCSK9-mAbs also significantly reduced lipoprotein (a) (Lp (a)), total cholesterol (TC), triglycerides (TG), apolipoprotein-B (Apo-B), and non-high-density lipoprotein cholesterol (non-HDL-C) levels and increased HDL-C and apolipoprotein-A1 (Apo-A1) levels of beneficial lipoproteins. Moreover, no significant difference was found between PCSK9-mAbs treatment and placebo in common adverse events, serious events, and laboratory adverse events. Conclusion. PCSK9-mAbs significantly decreased LDL-C and other lipid levels with satisfactory safety and tolerability in FH treatment.

AbstractObjectiveThe objective of this meta-analysis was to analyze the benefits and harms of treating the population with statins in those having mean low-density lipoprotein cholesterol (LDL-C) in the near-optimal (100 to 129 mg/dl) to borderline high (130 to 159 mg/dl) range and free of cardiovascular disease (CVD). Methods: We searched PubMed, PubMed Central, Cochrane Library, and Google Scholar databases for randomized controlled trials (RCTs) published between 1994 and July 2020. We included RCTs with greater than 90% of participants free of CVD. Two reviewers independently screened the articles using the Covidence software, assessed the methodological quality using the risk of bias 2 tool, and analyzed the data using the RevMan 5.4 software. Results: Eleven trials were included. Statin therapy was associated with a decreased risk of myocardial infarction (RR=0.56, 95% CI: 0.47 to 0.67), major cerebrovascular events (RR=0.78, 95% CI: 0.63 to 0.96), major coronary events (RR=0.67, 95% CI: 0.57 to 0.80), composite cardiovascular outcome (RR=0.71, 95% CI: 0.62 to 0.82), revascularizations (RR=0.65, 95% CI: 0.57 to 0.74), angina (RR=0.76, 95% CI: 0.63 to 0.92) and hospitalization for cardiovascular causes (RR=0.74, 95% CI: 0.64 to 0.86). There was no benefit associated with statin therapy for cardiovascular mortality and coronary heart disease mortality. All-cause mortality benefit with statin therapy was seen in the population with diabetes and increased risk of CVD. Statin therapy was associated with no significant increased risk of myalgia, creatine kinase elevation, rhabdomyolysis, myopathy, incidence of any cancer, incidence of diabetes, withdrawal of the drug due to adverse events, serious adverse events, fatal cancer, and liver enzyme abnormalities. Conclusion: Statin therapy was associated with a reduced risk of cardiovascular disease and procedures without increased risk of harm in populations with mean LDL-C near-optimal to the borderline high range without prior atherosclerotic cardiovascular disease.

Currently, statins are the first-line therapies for dyslipidemia and atherosclerotic cardiovascular disease, however, their hypolipidemic effects have not been satisfactory. We performed a meta-analysis to compare lipid-lowering efficacy and safety of ezetimibe and statin combination therapy with double-dose statin monotherapy in patients with high cardiovascular risk. Fourteen studies involving 3,105 participants were included in the final analysis; 1,558 (50.18%) participants received ezetimibe and statin combination therapy and 1,547 (49.82%) received double-dose statin monotherapy. Eight studies reported the percentages of changes in several lipid parameters from baseline to endpoint in both groups. Lipid parameters changed more significantly in patients co-administered with ezetimibe and statin (low-density lipoprotein cholesterol [LDL-C]: MD = -9.39, 95% CI -13.36 to -5.42; non-high-density lipoprotein cholesterol [non-HDL-C]: MD = -10.36, 95% CI -14.23 to -6.50; total cholesterol [TC]: MD = -8.11, 95% CI -10.95 to -5.26; and triglyceride [TG]: MD = -5.96, 95% CI -9.12 to -2.80), with moderate to high heterogeneity among the studies. Two out of fourteen studies investigated several different statins. Our subgroup analysis showed that, compared with double-dose atorvastatin monotherapy, ezetimibe and atorvastatin combination therapy significantly decreased LDL-C, non-HDL-C, TC, and TG levels by 14.16%, 14.01%, 11.06%, and 5.96%, respectively (p < 0.001). No significant difference was found in the incidence of laboratory-related adverse events (AEs) between statin combination therapy and monotherapy. Overall, ezetimibe and statin combination therapy significantly decreased LDL-C, non-HDL-C, and TC levels in patients with high cardiovascular risk, among which ezetimibe combined with atorvastatin had the best therapeutic effect. Compared with ezetimibe and statin combination therapy, double-dose statin monotherapy did not increase the risk of AEs.

There is an increasing prevalence of diabetes worldwide and substance abuse has been observed as a problem among some people with diabetes. Therefore, there is an urgent need to understand the association between unhealthy drug use including the abuse of opium and clinical outcomes including its impact on lipid profile in patients with diabetes as the presence of these conditions can increase the risk of cardiovascular morbidity and mortality. Aim: This was a systematic review and meta-analysis which evaluated the impact of opium abuse on lipid profile in patients with diabetes. Method: This systematic review was conducted in line with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Three databases (Embase, PubMed, and PsycINFO) plus Google Scholar were searched for relevant articles from database inception to 18 July 2019 based on the Population, Intervention, Comparator, and Outcomes (PICO) framework. The studies included were based on a set of inclusion and exclusion criteria including patients with diabetes who abused opium. Articles were evaluated for risk of bias and the meta-analysis was conducted using Revman. Results: Six articles that met the criteria were included in the systematic review and meta-analysis. The type of substance abused was opium in all the studies. The results of the meta-analysis showed that opium abuse significantly (P = 0.01) lowered total cholesterol compared to control with a mean difference of −0.17 (95% CI, −0.29, −0.04) in patients with diabetes. With respect to high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and body mass index, the differences were not statistically significant (P > 0.05) between those who abused opium compared with the control. Nutritional deficiencies, weight loss and lipid dysregulation due to liver dysfunction which are found in people who abuse substances may explain the findings of the current review with respect to lipid profile in patients with diabetes who abuse opium compared with the control. Conclusion: The findings of this systematic review and meta-analysis have shown that opium abuse significantly decreased total cholesterol (P < 0.05) in patients with diabetes. However, the effect of opium abuse on HDL cholesterol, triglycerides, body mass index (BMI) and LDL cholesterol in these patients were not statistically significant (P > 0.05) compared with the control. This result has public health significance in terms of ensuring the promotion of adequate nutritional intake in patients with diabetes who abuse opium.

Abstract Background Acute coronary syndrome (ACS) is a cardiac emergency with high mortality. Exposure to high copper (Cu) concentration has been linked to ACS. However, whether DNA methylation contributes to the association between Cu and ACS is unclear. Methods We measured methylation level at > 485,000 cytosine-phosphoguanine sites (CpGs) of blood leukocytes using Human Methylation 450 Bead Chip and conducted a genome-wide meta-analysis of plasma Cu in a total of 1243 Chinese individuals. For plasma Cu-related CpGs, we evaluated their associations with the expression of nearby genes as well as major cardiovascular risk factors. Furthermore, we examined their longitudinal associations with incident ACS in the nested case-control study. Results We identified four novel Cu-associated CpGs (cg20995564, cg18608055, cg26470501 and cg05825244) within a 5% false discovery rate (FDR). DNA methylation level of cg18608055, cg26470501, and cg05825244 also showed significant correlations with expressions of SBNO2, BCL3, and EBF4 gene, respectively. Higher DNA methylation level at cg05825244 locus was associated with lower high-density lipoprotein cholesterol level and higher C-reactive protein level. Furthermore, we demonstrated that higher cg05825244 methylation level was associated with increased risk of ACS (odds ratio [OR], 1.23; 95% CI 1.02–1.48; P = 0.03). Conclusions We identified novel DNA methylation alterations associated with plasma Cu in Chinese populations and linked these loci to risk of ACS, providing new insights into the regulation of gene expression by Cu-related DNA methylation and suggesting a role for DNA methylation in the association between copper and ACS.

AbstractDiabetes is a serious threat to global health and among the top 10 causes of death, with nearly half a billion people living with it worldwide. Treating patients with diabetes tend to become more challenging due to the progressive nature of the disease. The role and benefits of combination therapies for the management of type 2 diabetes are well-documented, while the comparative safety and efficacy among the different combination options have not been elucidated. We aimed to systematically synthesize the evidence on the comparative cardiovascular safety and efficacy of combination therapy with metformin-sodium-glucose cotransporter-2 inhibitors versus metformin-sulfonylureas in patients with type 2 diabetes. We searched MEDLINE-PubMed, Embase, Cochrane Library, and ClinicalTrials.gov up to 15 August 2019 without restriction in the year of publication. We included randomized controlled trials of patients with type 2 diabetes who were on metformin-sodium-glucose cotransporter-2 inhibitors or metformin-sulphonylureas combination therapy at least for a year. The primary endpoints were all-cause mortality and serious adverse events, and the secondary endpoints were cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke, hypoglycemia, and changes in glycated hemoglobin A1c (HbA1c), body weight, fasting plasma glucose, blood pressure, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. We used a random-effects meta-analysis model to estimate mean differences for continuous outcomes and risk ratio for dichotomous outcomes. We followed PICOS description model for defining eligibility and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015 guidelines for reporting results. Of 3,190 citations, we included nine trials involving 10,974 participants. The pooled analysis showed no significant difference in all-cause mortality (risk ration [RR] = 0.93, 95% CI [0.52, 1.67]), serious adverse events (RR = 0.96, 95% CI [0.79, 1.17]) and adverse events (RR = 1.00, 95% CI [0.99, 1.02]) between the two, but in hypoglycemia (RR = 0.13, 95% CI [0.10, 0.17], P < 0.001). Participants taking metformin-sodium glucose cotransporter-2 inhibitors showed a significantly greater reduction in HbA1c (mean difference [MD] = − 0.10%, 95% CI [− 0.17, − 0.03], body weight (MD = − 4.57 kg, 95% CI [− 4.74, − 4.39], systolic blood pressure (MD = − 4.77 mmHg, 95% CI [− 5.39, − 4.16]), diastolic blood pressure (MD = − 2.07 mmHg, 95% CI [− 2.74, − 1.40], and fasting plasma glucose (MD = − 0.55 mmol/L, 95% CI [− 0.69, − 0.41]), p < 0.001. Combination therapy of metformin and sodium-glucose cotransporter-2 inhibitors is a safe and efficacious alternative to combination therapy of metformin and sulphonylureas for patients with type 2 diabetes who are at risk of cardiovascular comorbidity. However, there remains a need for additional long-term randomized controlled trials as available studies are very limited and heterogeneous.
