Background: Proprotein convertase subtilisin/kexin type-9 (PCSK-9) is a serine protease with profound effects on plasma LDL-C, the major risk factor for cardiovascular diseases (CVDs). However, plasma PCSK-9 level and its association with the biomarkers of CVDs, diabetes, and associated complications have not yet been reported in the northeastern population of India.
Methods: Of the total cohort (n = 233), we analyzed healthy controls (HC; n = 50), freshly diagnosed type-2-diabetes mellitus (T2DM-FD; n = 46), T2DM treated (T2DM-T; n = 49), diabetic nephropathy (T2DM-N; n = 43), and diabetic dyslipidemia (T2DM-DL; n = 45) subjects. Plasma PCSK-9 and other biological determinants associated with T2DM, CVD, and nephrotic dysfunction were assessed.
Results: The level of plasma PCSK-9 in HC, T2DM-FD, T2DM-T, T2DM-N, and T2DM-DL groups was found to be 184.1 ± 13.83, 183.1 ± 24.4.3, 241.8 ± 75.42, 403.7 ± 85.94, and 641.3 ± 135.5 ng/mL, respectively, indicating its role in the severity of the here-mentioned complications. Moreover, plasma PCSK-9 levels further showed a significant correlation with the biomarkers of hyperglycemia, particularly HbA1c, as well as LDL-C in T2DM-FD, T2DM-N, and T2DM-DL subjects of the Indian population, while moderate association in T2DM-T subjects.
Conclusions: Our first-of-its-kind clinical study aiming to quantify the circulatory PCSK-9 level in the Indian population concluded that elevated PCSK-9 was significantly associated with the severity of diabetes and associated complications. Moreover, such elevation in PCSK-9 might be attributed to the lipid- and glucoselowering medication-induced SREBP-2-dependent mechanisms. Since our conclusion is based on a pilot study, further cohort studies in larger populations of India are required to get a generalization regarding the role of PCSK-9 in DM and associated complications.

Hyperlipidemia is a major contributor to metabolic complications and tissue damage, leading to conditions such as liver steatosis, atherosclerosis, and obesity. This study aimed to investigate the effects of aqueous artichoke bract extract (AE) on lipid metabolism, liver antioxidative defense, and liver steatosis in mice fed a high-fat, high-sucrose diet while elucidating the underlying mechanisms. An 8-week study used hyperlipidemic mice treated with AE at daily doses of 100 and 200 mg/kg bw, compared to fenofibrate.

Article Synopsis
- Lipoprotein(a) [Lp(a)] is recognized as a key independent risk factor for atherosclerotic cardiovascular disease (ASCVD), prompting research into various lipid-lowering drugs that might reduce its levels.
- A systematic review of 29 studies showed that traditional lipid-lowering agents like statins and fibrates generally do not significantly affect Lp(a) concentrations, whereas Lp(a) apheresis and PCSK-9 inhibitors were effective.
- Emerging RNA-targeting therapies, such as anti-sense oligonucleotides, demonstrated promise in lowering Lp(a) levels, but it's still unclear if these reductions will lead to fewer cardiovascular events in patients.

Metabolic syndrome (MetS) is an ever-evolving set of diseases that poses a serious health risk in many countries worldwide. Existing evidence illustrates that individuals with MetS have a 30%-40% higher chance of acquiring type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), or both. This study was undertaken to uncover the regulatory role of natural organosulfur compounds (OSCs), S-allyl-L-cysteine (SAC), and S-ethyl-L-cysteine (SEC), in targeting high carbohydrate high fat (HCHF)-diet-induced MetS-associated risk management.

Non-statin drugs find utility in the management of dyslipidaemia in mixed dyslipidaemia, patients with statin intolerance, and when guidelines directed low-density lipoprotein cholesterol (LDL-C) target cannot be achieved despite maximally tolerated statin. The most definite indication of fenofibrate monotherapy is fasting serum triglyceride >500 mg/dl to reduce the risk of acute pancreatitis It offers a modest reduction in cardiovascular events. The statin-ezetimibe combination is commonly used for lipid lowering particularly after ACS.
