SGLT2i impact on HCC incidence in patients with fatty liver disease and diabetes: a nation-wide cohort study in South Korea.

This study evaluated the effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i) on cancer development, particularly in hepatocellular carcinoma (HCC), in individuals with concomitant fatty liver disease (FLD) and type 2 diabetes mellitus (T2DM). Using data from Korea's Health Insurance Review and Assessment Service, we performed Kaplan-Meier and Cox regression analyses in patients with non-alcoholic fatty liver disease (NAFLD) and T2DM (NAFLD-T2DM cohort) and those with chronic viral hepatitis (CVH) alongside FLD and T2DM (FLD-T2DM-CVH cohort). In the propensity score (PS) matched NAFLD-T2DM cohort (N = 107,972), SGLT2i use was not associated with the occurrence of overall cancer, including HCC. However, old age, male sex, liver cirrhosis, and hypothyroidism were identified as independent risk factors for HCC occurrence, whereas statin and fibrate usage were associated with reduced HCC risk in this cohort in multivariate Cox analysis. In the PS-matched FLD-T2DM-CVH cohort (N = 2798), a significant decrease in HCC occurrence was observed among SGLT2i users (P = 0.03). This finding remained consistent in the multivariate Cox regression analysis (Hazard ratio = 2.21, 95% confidence interval = 1.01-4.85, P = 0.048). In conclusion, SGLT2i may be a beneficial option for diabetes management in patients with concomitant T2DM, FLD, and CVH while affirming the overall safety of SGLT2i in other types of cancer.

Statin use for cardiovascular disease prevention: perceptions among people living with HIV in the United States

BackgroundPeople living with HIV (PLWH) may be at heightened risk for cardiovascular disease (CVD). Statin use and lifestyle changes reduce the risk of CVD but remain under-prescribed among PLWH. The objective of this study was to characterize knowledge of CVD and statin use, current usage, barriers to taking statins, and information desired by PLWH to improve statin uptake among PLWH in Los Angeles, CA.MethodsBetween April 2019 and April 2020, we conducted four focus group discussions (n = 37) with patients across three public community health clinics that serve PLWH in Los Angeles County, California. All clinics participated in a larger study to improve statin prescribing for PLWH. We asked about knowledge of statins, willingness to take a statin, possible barriers to statin usage, preferred information sources for health information, and desired information about statins. We utilized standard qualitative content analysis methods to identify themes.ResultsWe found a range in the awareness of statins, with some participants reporting never having heard of statins while others had a history of statin use. There were concerns about the potential long-term effect of statin use, but participants expressed willingness to use CVD medications generally and statins specifically, especially if recommended by their healthcare provider. Participants also expressed interest in potential alternatives to statin usage such as exercising regularly and nutritious eating.ConclusionsMore interventions are needed to increase statin use among PLWH to improve CVD outcomes, which also has implications for HIV progression. Clinics should aim to increase patient and provider knowledge about CVD risk and statin use for PLWH and provide shared decision-making tools that are easy to use and culturally appropriate.

Statin use as a moderator on the association between metformin and breast cancer risk in women with type 2 diabetes mellitus

IntroductionMetformin and statins are considered as potential agents for prevention of breast cancer, however, existing evidence does not uniformly substantiate this claim, and the data is scarce concerning their interaction in relation to breast cancer risk. This study aims to investigate whether the effect of metformin on breast cancer incidence varied by statin use among women with type 2 diabetes mellitus (T2DM).MethodsThis study included women with T2DM, without a history of cancers, and followed up for more than one year from the Zwolle Outpatient Diabetes project Integrating Available Care (ZODIAC) for the period 1998–2014. The dataset was structured using a person-time approach, where the cumulative medication usage was annually updated for each person. The extended Cox proportional hazards models were employed, reporting adjusted hazard ratios (HR) with 95% confidence intervals (CI).ResultsDuring a median follow-up of 5 years, 515 of 29,498 women received a breast cancer diagnosis. Each additional year of metformin or statins use corresponded to a decrease in breast cancer incidence, while the magnitude attenuated over time. Noteworthily, statin use modified the effect of metformin on breast cancer incidence. For instance, after 5 years of follow-up, one-year increase of metformin use among women who used statins for 3 years was linked to a substantially reduced breast cancer risk (HR, 95% CI: 0.88, 0.84–0.93), however, there was no significant decrease in risk for those non-statins users (HR, 95% CI: 0.96, 0.89–1.04).ConclusionsExtending metformin or statin usage by one year conferred breast cancer protection in women with T2DM. Enhanced protective effect of metformin was observed among those who also use statins. These results suggest the potential of combined metformin and statin therapy as promising breast cancer prevention strategies.

Association between statin use and acute pulmonary embolism in intensive care unit patients with sepsis: a retrospective cohort study.

Acute pulmonary embolism (APE) is a life-threatening medical condition that is frequently encountered and associated with significant incidence and mortality rates, posing a substantial threat to patients' well-being and quality of life. Sepsis is prominent independent risk factor for the development of APE. Despite recent investigations indicating a reduced APE risk through statin therapy, its impact on patients with sepsis and APE remains unresolved. The Medical Information Mart for Intensive Care (MIMIC)-IV database was utilized to identify patients diagnosed with sepsis and APE, irrespective of statin treatment status, as part of this study. The primary study aim was to assess the risk of APE, which was analyzed using multivariate logistic regression models. The study encompassed a total of 16,633 participants, with an average age of 64.8 ± 16.2 years. Multivariate logistic regression revealed that septic patients receiving statin therapy in the intensive care unit (ICU) exhibited a 33% reduction in the risk of developing APE (OR = 0.67, 95% CI: 0.52-0.86, p < 0.001). The findings of further analyses, including stratification based on statin usage, dosage, and propensity score matching, consistently reinforced the hypothesis that administering statins to patients with sepsis effectively mitigates their potential APE risk. The results of the study provide compelling evidence in favor of administering statins to septic patients as a prophylactic measure against APE, given that statins may reduce the risk of developing APE, and their anti-APE effect appears to be dose-dependent. Nonetheless, future randomized controlled trials are needed to validate these results.

Statins as a risk factor for diabetic retinopathy: a Mendelian randomization and cross-sectional observational study

BackgroundDiabetic retinopathy (DR) is the foremost cause of vision loss among the global working-age population, and statins are among the most frequently prescribed drugs for lipid management in patients with DR. The exact relationship between statins and DR has not been determined. This study sought to validate the causal association between statins usage and diabetic retinopathy.MethodsThe summary-data-based Mendelian randomization (SMR) method and inverse-variance-weighted Mendelian randomization (IVW-MR) were used to identify the causal relationship between statins and DR via the use of expression quantitative trait loci (eQTL) data for 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) (31,684 blood samples), low density lipoprotein cholesterol-related GWAS data (sample size: 440,546), and DR-related GWAS data (14,584 cases and 176,010 controls). Additionally, a cross-sectional observational study based on the data from the National Health and Nutrition Examination Survey (NHANES) was conducted to supplement the association between DR and statins (sample size: 106,911). The odds ratios (ORs) with corresponding 95% confidence intervals (CIs) was employed to evaluate the results.ResultsBased on the results of the MR analysis, HMGCR inhibitors were causally connected with a noticeably greater incidence of DR (IVW: OR = 0.54, 95% CI [0.42, 0.69], p = 0.000002; SMR: OR = 0.66, 95% CI [0.52, 0.84], p = 0.00073). Subgroup analysis revealed that the results were not affected by the severity of DR. The sensitivity analysis revealed the stability and reliability of the MR analysis results. The results from the cross-sectional study based on NHANES also support the association between not taking statins and a decreased risk of DR (OR = 0.54, 95% CI [0.37, 0.79], p = 0.001).ConclusionsThis study revealed that a significant increase in DR risk was causally related to statins use, providing novel insights into the role of statins in DR. However, further investigations are needed to verify these findings.

The impact of the 2019 ESC/EAS dyslipidaemia guidelines on real-world initial lipid-lowering therapy in patients with acute myocardial infarction.

This study aimed to investigate the impact of the latest guidelines on the real-world clinical practice of initial lipid-lowering therapy, especially on the use of ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in China. All adult patients diagnosed with acute myocardial infarction in our hospital between August 31, 2018, and August 31, 2020, were divided into the following 2 groups: those patients treated before the latest guideline release, and those patients treated after the release. A propensity score-matched method was used, and logistic regression was used to assess the association with intensive statin, ezetimibe and PCSK9 inhibitor usage together with treatment results between the 2 groups. A total of 325 patients were enrolled in this study, including 141 patients who were admitted before the release of the latest guideline and 184 patients who were admitted after the release. After a median follow-up time of 8.20 months, the mean low-density lipoprotein cholesterol was 1.87 ± 0.59 mmol/L (1.87 ± 0.55 in the before group vs 1.88 ± 0.62 in the after group, P = .829). After propensity score matching, the initial usage of intensive statin therapy was decreased after guideline release without statistical significance (17.00% vs 28.00%, P = .090), whereas the usage of ezetimibe and PCSK9 inhibitors was increased (19.00% vs 8.00%, P = .039; and 10.00% vs 3.00%, P = .085, respectively). In logistic regression models, the release of the guideline was associated with a statistically significantly increased use of ezetimibe (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.21, 3.02; P = .005), a marginally decreased use of intensive statins (OR: 0.68; 95% CI: 0.45, 1.03; P = .069) and a marginally increased use of PCSK9 inhibitors (OR: 1.31; 95% CI: 0.98, 1.76; P = .068). In this single-center, real-world data analysis, after the release of the 2019 European Society of Cardiology/European Atherosclerosis Society guidelines, an increasing number of patients with a recent acute myocardial infarction were initially receiving ezetimibe and PCSK9 inhibitors.

Chinese Expert Consensus on the Clinical Diagnosis and Management of Statin Intolerance.

The clinical benefits of statins have well-established and recognized worldwide. Although statins are well-tolerated generally, however, the report of statin-related adverse event and statin intolerance are common in China, which results in insufficient use of statins and poor adherence. The main reason may be attributed to confusions or misconceptions in the clinical diagnosis and management in China, including the lack of unified definitions and diagnostic standards, broad grasp of diagnosis, and unscientific management strategies. Based on that, this consensus carefully summarized the statin-related gene polymorphism and statin usage issue among Chinese population, and comprehensively reviewed global research data on statin intolerance, referenced guidelines, and consensus literature on statin intolerance in foreign and different regions, proposes an appropriate and easy to implement statin intolerance definition as well as corresponding diagnostic criteria and management strategies for Chinese clinicians, in order to improve the clinical application of statin drugs and enhance the prevention and treatment level of atherosclerotic cardiovascular disease in China.

Causal modulation of lipid metabolism may shape the inflammatory microenvironment and potentially augment immunotherapy: a comprehensive genetic landscape revealed by Mendelian randomization analysis.

Previous observational and experimental studies have suggested a relationship between statin treatments and the augmentation of immunotherapy effects; however, the causal role of statin usage in promoting antitumor immunity remains largely unexplored. Utilizing large-scale genome-wide association studies, we conducted a Mendelian Randomization (MR) analysis to examine the association between genetically proxied inhibition of the gene for 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), a specific target of statins, and 524 immunotherapy-related profiles, encompassing immune cells, inflammatory cytokines, immune checkpoints, and gut microbiota. Our findings indicated a suggestive association between statin therapy and proinflammatory as well as antitumor effects; notably, inhibition of HMGCR demonstrated a robust link with increased susceptibility of various immune cell types, including basophil cells, white blood cells, eosinophil cells, neutrophil cells, activated CD8+ T cells, dendritic cells, and natural killer cells; furthermore, a causal relationship was observed between statin use and a decrease in terminal CD8+ T cells, granulocytes, monocytes, and myeloid-derived suppressor cells; genetically proxied statin usage was also significantly associated with elevated levels of proinflammatory cytokines and immunotherapy-related gut microbiota; importantly, the potential inhibition of HMGCR in influencing the response to immunotherapy was confirmed in the real-world cohorts. This study provides novel insights into the regulatory role of HMGCR inhibition in antitumor immunity, suggesting that strategies targeting HMGCR or lipid regulation may hold therapeutic potential for enhancing the efficacy of immunotherapy.

Sports-Statin Interaction: Ensuring Safe and Smart Synergy

Both sports (physical activity) and statins are recommended for the prevention and management of atherosclerotic cardiovasculardisease. The synergy that they create in risk reduction, however, may turn dysfunctional at times. Statin usage is associated witha risk of muscle-related conditions including myalgia, myositis and rhabdomyolysis. This risk is exacerbated by unaccustomedphysical activity, exercise or sports. The communication shares practical and pragmatic suggestions regarding the preventionand management of the potential sports-statin interactions that may occur. It also highlights the need to consider drug-lifestyleinteractions, apart from conventional drug-drug interactions.

Potential Benefits and Risks Associated with the Use of Statins.

HMG-CoA reductase inhibitors, commonly known as statins, are the primary treatment choice for cardiovascular diseases, which stand as the leading global cause of mortality. Statins also offer various pleiotropic effects, including improved endothelial function, anti-inflammatory properties, reduced oxidative stress, anti-thrombotic effects, and the stabilization of atherosclerotic plaques. However, the usage of statins can be accompanied by a range of adverse effects, such as the development of type 2 diabetes mellitus, muscular symptoms, liver toxicity, kidney diseases, cataracts, hemorrhagic strokes, and psychiatric complications. These issues are referred to as statin-associated symptoms (SAS) and are relatively infrequent in clinical trials, making it challenging to attribute them to statin use definitively. Therefore, these symptoms can lead to significant problems, necessitating dose adjustments or discontinuation of statin therapy. This review aims to provide a comprehensive overview of the mechanism of action, potential advantages, and associated risks of statin utilization in clinical settings.

The Regulatory Variant -108C/T in the Promoter of Paraoxonase 1 (PON1) Gene has a More Important Role in Regulating PON1 Activity Compared to rs3735590 in 3'-UTR in Patients with Coronary Artery Disease.

This study aimed to assess the serum activity of paraoxonase 1 (PON1) in patients with coronary artery disease (CAD) based on two genetic variants including the -108C/T variant in the promoter region and the rs3735590 variant in the binding site of miR-616 at the 3'-UTR of the PON1 gene. A total of 140 subjects who exhibited clinical symptoms of CAD underwent diagnostic coronary angiography. The patients with CAD were further categorized into two groups: single-vessel disease (SVD) and multi-vessel disease (MVD). The study variants were genotyped using the restriction fragment length polymorphism (RFLP) technique after polymerase chain reaction amplification. After adjusting for age, gender, body mass index, metformin, and statin usage, a significant association was observed between the -108C/T variant and PON1 activity (P < 0.001). In the sub-groups of both SVD and MVD, individuals with the TC+CC genotypes exhibited significantly higher PON1 activity compared to TT homozygotes (P = 0.001 for SVD and P = 0.01 for MVD). As for the rs3735590 variant, individuals with the A allele (GA+AA genotypes) had higher PON1 activity compared to those with the GG genotype in both the SVD and MVD groups, although the results did not reach statistical significance. Our study findings indicate a significant decrease in PON1 activity among patients with obstructive CAD. Notably, our results suggest that the -108C/T variant exerts a greater influence on PON1 activity compared to the rs3735590 variant. These findings highlight the crucial role of the -108C/T variant in modulating PON1 activity within the context of atherosclerosis.

Association between Statin Use and Clinical Outcomes in Patients with De Novo Metastatic Prostate Cancer: A Propensity Score-weighted Analysis.

Numerous studies have produced conflicting findings regarding the efficacy of statins in prostate cancer treatment. Our objective was to examine the correlation between statin usage and clinical outcomes in Taiwanese men with de novo metastatic prostate cancer. We identified patients diagnosed with de novo metastatic prostate cancer from the Chang Gung Research Database spanning the years 2007 to 2020. To minimize confounding bias, we employed the inverse probability of treatment weighting (IPTW) method. Clinical outcomes were assessed using IPTW-adjusted Kaplan-Meier curves. Multivariate Cox proportional hazard regression analysis was utilized to evaluate the association between mortality and clinical factors. The study cohort comprised 1,716 statin users and 276 non-users. Patients who used statins exhibited a longer median overall survival (85.4 months compared to 58.2 months; p=0.001) and cancer-specific survival (112.6 months compared to 75.7 months; p<0.001) compared to non-users. The median time to the development of castration-resistant status was similar between statin users and non-users (p=0.069). Multivariable Cox proportional hazards regression analysis, after IPTW adjustment, demonstrated that statin use was associated with improved overall survival. Our study indicates that the use of statins following a de novo metastatic prostate cancer diagnosis enhances survival outcomes. However, statins did not appear to delay the onset of castration-resistant status. Further large-scale and long-term studies are warranted to investigate the biological effects of statins in men with prostate cancer.

Study on the 5-year trend and influencing factors of lipoprotein (a) concentration in community-based population

Objective: To explore the trend and influencing factors of serum lipoprotein (a) (Lp(a)) concentration over time in Chinese community populations. Methods: This study is a prospective cohort study. The participants were enrolled from Chinese Multi-provincial Cohort Study- Beijing projects, completed the cardiovascular disease risk factor surveys in 2002 and 2007, and the serum Lp (a) concentration were measured. Based on the Lp(a) concentration at baseline (2002) and follow-up (2007), the participants were classified into subgroups of <30.0 mg/dl (1 mg/dl=0.01 g/L) group, 30.0 to 49.9 mg/dl group, and ≥50.0 mg/dl group, respectively. Multivariable logistic regression analysis was used to identify influencing factors associated with Lp (a) absolute change (≥20 mg/dl) and relative change (≥20%) within 5 years. Results: Among 1 955 participants with age of (56.5±8.0) years old and 821 male (42.0%) at baseline, there were 1 657 (84.8%), 184 (9.4%) and 114 (5.8%) participants in Lp(a)<30.0 mg/dl group, 30.0 to 49.9 mg/dl group and ≥50.0 mg/dl group, respectively. Among the baseline Lp(a) concentration of 30.0-49.9 mg/dl group, 68 (37.0%) participants progressed to Lp(a) ≥50.0 mg/dl after 5 years follow-up, and 102 (55.4%) remained at this level. Participants with baseline Lp(a)<30.0 mg/dl (92%, 1 524/1 657) or Lp(a)≥50.0 mg/dl (94.7%, 108/114) tended to be maintained at their respective levels. The results of the multivariate logistic regression analysis showed that, in addition to the high level of baseline Lp(a) concentration, family history of cardiovascular disease, elevated fasting blood glucose and usage of oral lipid-lowering drugs were the influencing factors of Lp(a) changes over time (P<0.05). Conclusions: Adults with borderline-high Lp(a) concentrations (30.0 to 49.9 mg/dl) could be considered for repeated testing, especially for those with a family history of cardiovascular disease, elevated fasting blood glucose and usage of statins.

Protective Effects Against Dementia Undergo Different Statin Type, Intensity, and Cumulative Dose in Older Adult Type 2 Diabetes Mellitus Patients

ObjectivesThis study investigated the relationship between statin use and dementia risk in older adults with type 2 diabetes (T2DM). It also assessed the impact of various statin types, dosage intensity, and cumulative doses on dementia risk. DesignEmploying the inverse probability of treatment weighting (IPTW) Cox hazards model, this research explored the influence of statin utilization on dementia incidence. Setting and ParticipantsThe study included older adult T2DM patients aged 60 years or older who received statins (case group) and those who did not (control group) during the follow-up period. MethodsThe IPTW Cox hazards model quantified the association between statin use and dementia incidence. Subgroup analyses investigated different statin types, usage intensity, and cumulative dose–dependent relationships with dementia risk, measured by adjusted hazard ratios (aHRs) with corresponding 95% CIs. ResultsStatin users experienced a significant reduction in dementia risk (aHR: 0.47, 95% CI: 0.46-0.48). Subgroup analysis using IPTW Cox regression revealed varying dementia incidence reductions among users of different statin types, with aHRs (95% CIs) ranging from 0.09 to 0.69. Multivariate analyses unveiled a dose-dependent relationship, showing reduced dementia incidence based on cumulative defined daily doses (cDDDs) per year. The corresponding aHRs (95% CIs) were 0.20 to 0.72 across quartiles 4 to 1 of cDDD-years, with a significant trend (P < .001). The optimal daily statin use was 0.88 defined daily doses (DDDs), associated with the lowest dementia risk. Conclusions and ImplicationsStatins significantly reduced dementia risk in older adult T2DM patients. Higher cumulative defined daily doses (cDDD-years) were linked to more substantial risk reductions. This research underscores the clinical benefits of statin use in preventing dementia in this population and calls for further investigation into the underlying mechanisms. It also raises the possibility of influencing policy decisions to manage dementia risk in this vulnerable group.

Low-Density Lipoprotein Cholesterol and Statin Usage Are Associated With Rates of Pseudarthrosis Following Single-Level Posterior Lumbar Interbody Fusion.

Retrospective cohort study. To investigate the relationships of low-density lipoprotein cholesterol and statin usage with pseudarthrosis following single-level posterior or transforaminal lumbar interbody fusion (PLIF/TLIF). Hypercholesterolemia can lead to atherosclerosis of the segmental arteries, which branch into vertebral bone through intervertebral foramina. According to the vascular hypothesis of disc disease, this can lead to ischemia of the lumbar discs and contribute to lumbar degenerative disease. Yet, little has been reported regarding the effects of cholesterol and statins on the outcomes of lumbar fusion surgery. TriNetX, a global federated research network, was retrospectively queried to identify 52,140 PLIF/TLIF patients between 2002 and 2021. Of these patients, 2137 had high cholesterol (≥130mg/dL) and 906 had low cholesterol (≤55 mg/dL). Perioperatively, 18,275 patients used statins, while 33,415 patients did not. One-to-one propensity score matching for age, sex, race, and comorbidities was conducted to balance the analyzed cohorts. The incidence of pseudarthrosis was then assessed in the matched cohorts within the six-month, one-year, and two-year postoperative periods. After propensity score matching, high-cholesterol patients had greater odds of developing pseudarthrosis six months [odds ratio (OR): 1.73, 95% confidence interval (CI): 1.28-2.33], one year (OR: 1.59, 95% confidence interval (CI): 1.20-2.10), and two years (OR: 1.57, 95% CI: 1.20-2.05) following a PLIF/TLIF procedure. Patients with statin usage had significantly lower odds of developing pseudarthrosis six months (OR: 0.74, 95% CI: 0.69-0.79), one year (OR: 0.76, 95% CI: 0.71-0.81), and two years (OR: 0.77, 95% CI: 0.72-0.81) following single-level PLIF/TLIF. The findings suggest that patients with hypercholesterolemia have an increased risk of developing pseudarthrosis following PLIF/TLIF while statin use is associated with a decreased risk. The data presented may underscore an overlooked opportunity for perioperative optimization in lumbar fusion patients, warranting further investigation in this area.

Comparative Analysis of High-Intensity versus Low-to-Moderate Intensity Statin Therapy in Patients Undergoing Rotational Atherectomy for Calcified Coronary Artery Disease.

(1) Background: Moderate-intensity statin therapy, when compared to high-intensity statin therapy in Asian populations, has shown no significant difference in cardiovascular prognosis in small studies. The aim of this study was to compare the prognosis of patients based on statin intensity following rotational atherectomy (RA) during high-complexity percutaneous coronary intervention (PCI). (2) Methods: The ROCK registry, a multicenter retrospective study, included patients who had undergone rotational atherectomy (RA) during percutaneous coronary intervention (PCI) at nine tertiary medical centers in South Korea between January 2010 and October 2019. The patients were divided into high-intensity statin (H-statin) and moderate/low-intensity statin (M/L-statin) therapy groups. The primary endpoint includes outcomes (cardiac death, target vessel myocardial infarction (MI), and target vessel revascularization (TVR)) within an 18-month follow-up period. (3) Results: In this registry, a total of 540 patients with 583 lesions were included. We excluded 39 lesions from the analysis due to the absence of statin usage. The H-statin group had 394 lesions and the M/L-statin group had 150 lesions. There were no significant differences in baseline characteristics, procedural adverse events without heart failure history, triglycerides, or medications between the two groups. The procedural success rate showed a significant difference between the two groups. Multivariate analysis did not show a significant association between M/L-statin therapy and an increased risk of the primary endpoint. In propensity score matching analysis, no significant difference was observed in the primary endpoint either. (4) Conclusions: In high-complex RA PCI, moderate/low-intensity statin therapy is not inferior to high-intensity statin therapy in Korea.

Abstract 13312: Statin Signature: Using Proteomics to Detect Pharmacological Fingerprints

Introduction: Lowering low-density lipoprotein cholesterol with statin therapy is a primary strategy for reducing cardiovascular morbidity and mortality. Yet, adherence to and persistence with statin medication is generally low, complicating the ability to evaluate whether treatment is effective. Hypothesis: Statin treatment may yield significant differences in abundances of proteins detectable in blood samples. Using machine learning and high-throughput proteomics, a blood-based biomarker test can be developed to assess statin medication compliance and demonstrate drug fingerprinting useful for clinical trials. Methods: Using modified-aptamer proteomics technology, SomaScan® assay v4.0, we assessed ∼5,000 proteins in 8,395 EDTA plasma samples from individuals aged 29-64 at visit 1 of the Fenland study, totaling ∼42 million protein measurements. A total of 305 individuals (3.6%) reported active statin medication use at this study visit. Predicted statin use was modeled with protein measurements using machine learning methods in 70% of Fenland as a training dataset. A hold-out dataset was used to assess model performance. A predictive model using elastic net logistic regression was optimized based on AUC and robustness to assay noise and sample handling conditions to detect a signature of statin usage. Results: A total of 839 proteins differed significantly between the ‘active statin’ and ‘no statin’ use groups in univariate analysis (FDR &lt;0.01). Eight of the top 50 significant proteins have known mechanistic associations with statin pharmacology, including HMGCS1, PCSK9, and APOB. A six-protein model was developed with an AUC of 0.91 (sensitivity=0.82, specificity=0.88) and 0.90 (sensitivity=0.80, specificity=0.87) on the training and hold-out datasets, respectively, to predict whether a statin signature is present or not. Conclusions: We successfully developed a blood-based protein-only model that detects mechanistically-relevant protein changes to predict active statin use in adults. The protein model could compliment self-reported medication status in clinical trials and in healthcare.

Influence of Socioeconomic Gender Inequality on Sex Disparities in Prevention and Outcome of Cardiovascular Disease: Data From a Nationwide Population Cohort in China.

Background Knowledge gaps remain in how gender-related socioeconomic inequality affects sex disparities in cardiovascular diseases (CVD) prevention and outcome. Methods and Results Based on a nationwide population cohort, we enrolled 3 737 036 residents aged 35 to 75 years (2014-2021). Age-standardized sex differences and the effect of gender-related socioeconomic inequality (Gender Inequality Index) on sex disparities were explored in 9 CVD prevention indicators. Compared with men, women had seemingly better primary prevention (aspirin usage: relative risk [RR], 1.24 [95% CI, 1.18-1.31] and statin usage: RR, 1.48 [95% CI, 1.39-1.57]); however, women's status became insignificant or even worse when adjusted for metabolic factors. In secondary prevention, the sex disparities in usage of aspirin (RR, 0.65 [95% CI, 0.63-0.68]) and statin (RR, 0.63 [95% CI, 0.61-0.66]) were explicitly larger than disparities in usage ofangiotensin-converting enzyme inhibitors/angiotensin receptor blockers (RR, 0.88 [95% CI, 0.84-0.91]) or β blockers (RR, 0.67 [95% CI, 0.63-0.71]). Nevertheless, women had better hypertension awareness (RR, 1.09 [95% CI, 1.09-1.10]), similar hypertension control (RR, 1.01 [95% CI, 1.00-1.02]), and lower CVD mortality (hazard ratio, 0.46 [95% CI, 0.45-0.47]). Heterogeneities of sex disparities existed across all subgroups. Significant correlations existed between regional Gender Inequality Index values and sex disparities in usage of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (Spearman correlation coefficient, r=-0.57, P=0.0013), hypertension control (r=-0.62, P=0.0007), and CVD mortality (r=0.45, P=0.014), which remained significant after adjusting for economic factors. Conclusions Notable sex disparities remain in CVD prevention and outcomes, with large subgroup heterogeneities. Gendered socioeconomic factors could reinforce such disparities. A sex-specific perspective factoring in socioeconomic disadvantages could facilitate more targeted prevention policy making.

Association of 25-hydroxyvitamin D levels with lipid profiles in osteoporosis patients: a retrospective cross-sectional study

BackgroundIn the literature, scarce data investigate the link between 25-hydroxyvitamin D (25[OH]D) and blood lipids in the osteoporosis (OP) population. 25(OH)D, as a calcium-regulating hormone, can inhibit the rise of parathyroid hormone, increase bone mineralization to prevent bone loss, enhance muscle strength, improve balance, and prevent falls in the elderly. This retrospective cross-sectional study aimed to investigate the association between serum 25(OH)D levels and lipid profiles in patients with osteoporosis, with the objective of providing insight for appropriate vitamin D supplementation in clinical settings to potentially reduce the incidence of cardiovascular disease, which is known to be a major health concern for individuals with osteoporosis.MethodsThis is a retrospective cross-sectional study from the Affiliated Kunshan Hospital of Jiangsu University, including 2063 OP patients who received biochemical blood analysis of lipids during hospitalization from January 2015 to March 2022. The associations between serum lipids and 25(OH)D levels were examined by multiple linear regression. The dependent variables in the analysis were the concentrations of serum lipoprotein, total cholesterol (TC), triglycerides (TGs), apolipoprotein-A, lipoprotein A, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol (LDL-C). The independent variable was the concentration of blood serum 25(OH)D. At the same time, age, body mass index, sex, time and year of serum analysis, primary diagnosis, hypertension, diabetes, statins usage, beta-C-terminal telopeptide of type I collagen, procollagen type I N-terminal propeptide were covariates. Blood samples were collected in the early morning after the overnight fasting and were analyzed using an automated electrochemiluminescence immunoassay on the LABOSPECT 008AS platform (Hitachi Hi-Tech Co., Ltd., Tokyo, Japan). The generalized additive model was further applied for nonlinear associations. The inception result for smoothing the curve was evaluated by two-piecewise linear regression exemplary.ResultsOur results proved that in the OP patients, the serum 25(OH)D levels were inversely connected with blood TGs concentration, whereas they were positively associated with the HDL, apolipoprotein-A, and lipoprotein A levels. In the meantime, this research also found a nonlinear relationship and threshold effect between serum 25(OH)D and TC, LDL-C. Furthermore, there were positive correlations between the blood serum 25(OH)D levels and the levels of TC and LDL-C when 25(OH)D concentrations ranged from 0 to 10.04 ng/mL. However, this relationship was not present when 25(OH)D levels were higher than 10.04 ng/mL.ConclusionsOur results demonstrated an independent relationship between blood lipids and vitamin D levels in osteoporosis patients. While we cannot establish a causal relationship between the two, our findings suggest that vitamin D may have beneficial effects on both bone health and blood lipid levels, providing a reference for improved protection against cardiovascular disease in this population. Further research, particularly interventional studies, is needed to confirm these associations and investigate their underlying mechanisms.
