Role of vaccination in patients with human monkeypox virus and its cardiovascular manifestations.

Human monkeypox, caused by the monkeypox virus (MPXV), is an emerging infectious disease with the potential for human-to-human transmission and diverse clinical presentations. While generally considered milder than smallpox, it can lead to severe cardiovascular complications. The virus primarily spreads through contact with infected animals or through human-to-human transmission. Cardiovascular involvement in human monkeypox is rare but has been associated with myocarditis, pericarditis, arrhythmias, and even fulminant myocardial infarction. Vaccination plays a crucial role in preventing and controlling monkeypox, but the eradication of smallpox has left global populations vulnerable. This review explores the cardiovascular manifestations of human monkeypox, the role of vaccination in disease prevention, and the importance of continued research and development of effective vaccines to protect against this emerging infectious threat. The global impact of monkeypox outbreaks, particularly on vulnerable populations, further highlights the importance of understanding and addressing this disease.

Role of PCSK9 inhibition during the inflammatory stage of SARS-COV-2: an updated review.

The potential role of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition in the management of COVID-19 and other medical conditions has emerged as an intriguing area of research. PCSK9 is primarily known for its impact on cholesterol metabolism, but recent studies have unveiled its involvement in various physiological processes, including inflammation, immune regulation, and thrombosis. In this abstract, the authors review the rationale and potential implications of PCSK9 inhibition during the inflammatory stage of SARS-CoV-2 infection. Severe cases of COVID-19 are characterized by an uncontrolled inflammatory response, often referred to as the cytokine storm, which can lead to widespread tissue damage and organ failure. Preclinical studies suggest that PCSK9 inhibition could dampen this inflammatory cascade by reducing the production of pro-inflammatory cytokines. Additionally, PCSK9 inhibition may protect against acute respiratory distress syndrome (ARDS) through its effects on lung injury and inflammation. COVID-19 has been linked to an increased risk of cardiovascular complications, especially in patients with pre-existing cardiovascular conditions or dyslipidemia. PCSK9 inhibitors are known for their ability to lower low-density lipoprotein (LDL) cholesterol levels by enhancing the recycling of LDL receptors in the liver. By reducing LDL cholesterol, PCSK9 inhibition might protect blood vessels from further damage and lower the risk of atherosclerotic plaque formation. Moreover, PCSK9 inhibitors have shown potential antithrombotic effects in preclinical studies, making them a potential avenue to mitigate the increased risk of coagulation disorders and thrombotic events observed in COVID-19. While the potential implications of PCSK9 inhibition are promising, safety considerations and possible risks need careful evaluation. Hypocholesterolemia, drug interactions, and long-term safety are some of the key concerns that should be addressed. Clinical trials are needed to establish the efficacy and safety of PCSK9 inhibitors in COVID-19 patients and to determine the optimal timing and dosing for treatment. Future research opportunities encompass investigating the immune response, evaluating long-term safety, exploring combination therapy possibilities, and advancing personalized medicine approaches. Collaborative efforts from researchers, clinicians, and policymakers are essential to fully harness the therapeutic potential of PCSK9 inhibition and translate these findings into meaningful clinical outcomes.

A Systematic Review and Meta-Analysis on the Efficacy and Safety of Finerenone Therapy in Patients with Cardiovascular and Chronic Kidney Diseases in Type 2 Diabetes Mellitus.

The purpose of this study is to assess the safety and efficacy of finerenone therapy in type 2 diabetes mellitus (T2DM) patients with cardiovascular and chronic renal diseases. This meta-analysis assesses the efficacy and safety of finerenone in the treatment of diabetic kidney disease (DKD). A comprehensive search of PubMed, Embase, and Google Scholar databases was performed to identify relevant randomized controlled trials (RCTs). To quantify the effects of finerenone, the analysis included the estimation of aggregated mean differences (MDs) and relative risks (RRs), as well as 95% confidence intervals (CIs). This meta-analysis included seven double-blind trials with patients suffering from chronic kidney disease (CKD) and T2D. Participants received finerenone or a placebo was assigned at random. The primary efficacy outcomes were cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke, hospitalization for heart failure, kidney failure, a sustained 57% decrease in the estimated glomerular filtration rate from baseline over four weeks, or renal death. Among the 39,995 patients included in the analysis, finerenone treatment was associated with a lower risk of cardiovascular and renal-related mortality compared to placebo (RR = 0.86 (0.80, 0.93), p = 0.0002; I-squared statistic (I2 ) = 0%) and (RR = 0.56 (0.17, 1.82), p = 0.34; I2 = 0%). In addition, finerenone treatment was associated with a marginally reduced risk of serious adverse events (RR = 0.95 (0.92, 0.97), p = 0.0001; I2 = 0%), although no significant difference in the overall risk of adverse events was observed between the two groups (RR = 1.00 (0.99, 1.01), p = 0.56; I2 = 0%). This study's findings suggest that finerenone administration can reduce the risk of end-stage kidney disease, renal failure, cardiovascular mortality, and hospitalization. Patients with both T2DM and CKD are therefore advised to consider finerenone therapy.

Efficacy and Safety of Pitavastatin in Patients with Impaired Glucose Tolerance: An Updated Review.

This review provides an updated overview of the efficacy and safety of pitavastatin in patients with impaired glucose tolerance (IGT). IGT is a prediabetic state characterized by elevated blood glucose levels that do not meet the criteria for diabetes. The review explores the potential benefits of pitavastatin in reducing cardiovascular risk and improving lipid profiles in individuals with IGT. It also examines the glycemic effects of pitavastatin, including its impact on fasting blood glucose levels, insulin sensitivity, and beta-cell function. The review highlights the need for individualized treatment approaches, taking into account the patient's overall cardiovascular risk profile and glycemic control needs. While pitavastatin has shown modest improvements in glycemic control, it is not a substitute for lifestyle modifications or standard antidiabetic medications. Future directions for research include long-term follow-up studies, mechanistic investigations, and comparative analyses to further understand the glycemic effects of pitavastatin in IGT. Overall, this narrative review provides valuable insights for healthcare professionals involved in the management of individuals with IGT, emphasizing the importance of a comprehensive approach to reduce cardiovascular risk and optimize glycemic control.

Effect of the Polypill on Adherence and Prevention of Cardiovascular Diseases in Patients With or at High Risk of Cardiovascular Diseases: A Meta-Analysis of Randomized Controlled Trials.

It is important to understand the role of polypills on medication adherence and clinical outcomes in patients with or at high risk of cardiovascular diseases (CVD) to help decision-makers make robust guidelines on using polypills in these people. Therefore, the current meta-analysis was conducted to assess the impact of polypills on medication adherence and clinical outcomes in patients with or at high risk of CVD. The present meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. We searched the electronic databases PubMed, Embase, and the Cochrane Library for randomized control trials (RCTs) from inception to January 1, 2023. The outcomes assessed in the present meta-analysis were adherence to prescribed drugs at the study end, the incidence of cardiovascular events, and change in low-density lipoprotein cholesterol (LDL-C), total cholesterol, and high-density lipoprotein (HDL) from baseline to the study end in mmol/l. A total of six studies were included in the present meta-analysis, with a total sample size of 13139 (6577 in the polypill group and 6562 in the control group). Meta-analysis showed that medication adherence was significantly higher in patients receiving polypills compared to the control group (relative risk (RR): 1.38, 95% confidence interval (CI): 1.22-1.56, p-value: 0.001). The risk of a cardiovascular event was significantly lower in the polypill group (RR: 0.72, 95% CI: 0.63-0.82, p-value: 0.001). No significant differences were found in the changes in LDL-C and total cholesterol between the two groups. This meta-analysis shows a significant impact of polypills on medication adherence. We also found that polypills can reduce the incidence of cardiovascular events in patients with or at high risk of CVD. Our study has also shown that regardless of the history of CVD, polypills play an important role in promoting medication adherence in patients with and without a history of CVD.
