BACKGROUND AND AIM: Rheumatoid arthritis is associated with increased morbidity and mortality due to atherosclerotic cardiovascular diseases. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an enzyme of phospholipase A2; it plays an important role in inflammation and atherosclerosis. Herein we aimed to investigate whether Lp-PLA2 activity is associated with atherosclerosis in patients with rheumatoid arthritis and compare the Lp-PLA2 activity with carotid intima media thickness (CIMT)...

Lipoprotein-associated phospholipase A2 (Lp-PLA2) levels are associated with the development of atherosclerosis. We aimed to assess the genetic determinants of Lp-PLA2 activity and mass by genotyping multiple polymorphisms in PLA2G7, the gene encoding Lp-PLA2, among 1258 participants from the Chinese Multi-provincial Cohort Study-Beijing Project. The Sequenom MassARRAY system, Taqman assay and direct sequencing were adopted. For the first time, the rs13218408 polymorphism was found to be significantly associated with reduced Lp-PLA2 levels...

OBJECTIVES: Measuring lipoprotein-associated phospholipase A2 (Lp-PLA2) activity can aid in identifying individuals at higher risk of coronary heart disease. However, the biological variation of Lp-PLA2 activity and corresponding reference change value (RCV) is unknown which limits interpretation of results. In this study we aim to define the intra- and inter-individual variability of Lp-PLA2 activity in a healthy reference population. METHODS: A total of 24 healthy individuals (22-47years of age) were prospectively collected at several time points: daily for five days (after overnight fast), daily for three days (while non-fasting), weekly for four weeks (after overnight fast), and monthly for 6months (after overnight fast)...

BACKGROUND: China has the highest absolute disease burden of diabetes worldwide. For diabetic patients, diabetes-related vascular complications are major causes of morbidity and mortality. The roles of lipoprotein-associated phospholipase A2 (Lp-PLA2) and secretory phospholipase A2 (sPLA2) as inflammatory markers have been recently evaluated in the pathogenesis of both diabetes and atherosclerosis. We aimed to determine the mechanism through which patients with newly diagnosed type 2 diabetes gain long-term vascular benefit from intensive insulin therapy by evaluating the change in Lp-PLA2 and sPLA2 levels after early intensive insulin treatment and its relevance with insulin resistance and pancreatic β-cell function...

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an independent risk factor for plaque rupture and atherothrombotic events. However, the associations between serum Lp-PLA2 level and thrombus burden in ST-segment elevation myocardial infarction (STEMI) patients remain unknown.We consecutively enrolled 351 STEMI patients who underwent primary percutaneous coronary intervention (pPCI). Patients were assigned to a high thrombus burden (HTB) group (n = 230) and a low thrombus burden (LTB) group (n = 121). Baseline data were recorded during hospital admission...

BACKGROUND: Diet and smoking are the main sources of cadmium exposure in the general population. Cadmium increases the risk of cardiovascular diseases, and experimental studies show that it induces inflammation. Blood cadmium levels are associated with macrophages in human atherosclerotic plaques. Soluble urokinase-type plasminogen activator receptor (suPAR) is an emerging biomarker for cardiovascular events related to inflammation and atherosclerotic plaques. The aim was to examine whether blood cadmium levels are associated with circulating suPAR and other markers of inflammation...

BACKGROUND: This study aims to test the lipoprotein-associated phospholipase A2 (Lp-PLA2) mass and activity in patients with chronic kidney disease (CKD) and to analyze their connection of Lp-PLA2 with the development of disease and with the occurrence of atherosclerosis in this population. MATERIALS AND METHODS: In total, 59 patients older than 18 years and with a diagnosis of CKD were recruited. Kidney function was evaluated by serum creatinine, serum urea and estimated glomerular filtration rate according to Chronic Kidney Disease Epidemiology Collaboration formula and clinical data were collected...

OBJECTIVE: Increased transient receptor potential canonical type 3 (TRPC3) channels have been observed in essential hypertensive patients and spontaneously hypertensive rats (SHR). Our previous study shows that mitochondrial respiratory dysfunctions of blood mononuclear cells link with cardiac disturbance in patients with early-stage heart failure. Telmisartan has beneficial effect on both hypertension and metabolic syndrome. In the present study we tested the hypothesis that telmisartan administration inhibited mitochondrial respiratory function was associated with decreased TRPC3 function in monocytes from genetic hypertensive rats (SHR)...

OBJECTIVE: Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians, whereas whites tend to have more extracranial lesions. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been associated with ischemic stroke by a large amount of work. However, there are few studies focusing on the relationship of Lp-PLA2 and asymptomatic ICAS or extracranial arterial stenosis (ECAS). We hereby sought to explore the relationship of Lp-PLA2 and ICAS, ECAS and concurrent stenosis in stroke-free hypertensive patients in Chinese population...

BACKGROUND: Initiation of antiretroviral therapy (ART) and subsequent virologic suppression reduces immune activation and systemic inflammation. METHODS: We examined longitudinal changes in biomarkers of monocyte activation (sCD14, sCD163), and systemic (IL-6, hsCRP, sTNFR-I and D-dimer) and vascular (Lp-PLA2) inflammation in a subgroup (N=100 per arm) of participants enrolled in a randomized, placebo-controlled trial comparing elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF; TAF) to E/C/F/tenofovir disoproxil fumarate (E/C/F/TDF; TDF) in treatment-naïve adults...

BACKGROUND: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the primary omega-3 fatty acids in fish oil, have been shown to reduce cardiovascular disease (CVD) risk. OBJECTIVE: This study aimed to examine the independent effects of EPA and DHA on lipid and apolipoprotein levels, as well as on inflammatory biomarkers of CVD risk, using doses often used in the general population. DESIGN: A blinded, randomized 6-week trial was performed in 121 healthy, normolipidemic subjects who received olive oil placebo 6g/d, EPA 600mg/d, EPA 1800mg/d, or DHA 600mg/d...

BACKGROUND AND AIMS: Type 2 diabetes (T2D), low-density lipoprotein-cholesterol (LDL-c), body mass index (BMI), blood pressure and smoking are established risk factors that play a causal role in coronary artery disease (CAD). Numerous common genetic variants associating with these and other risk factors have been identified, but their association with CAD has not been comprehensively examined in a single study. Our goal was to comprehensively evaluate the associations of established and emerging risk factors with CAD using genetic variants identified from Genome-wide Association Studies (GWAS)...

BACKGROUND: Chest imaging is performed for a variety of reasons in HIV-infected adults. There are limited data on the prevalence of incidental findings, progression of these findings over time and the relationship with inflammation in antiretroviral therapy (ART)-treated HIV-infected adults. METHODS: This study utilized data from a randomized clinical trial of rosuvastatin in HIV-infected adults on ART. Incidental findings were reported from chest computed tomography (CT) scans obtained for coronary artery calcium score at entry, week 48 and 96...

AIM: Aspirin resistance has an incidence of 5%-65% in patients with ischemic stroke, who receive the standard dose of aspirin, but the platelet function is inadequately inhibited, thereby leading to thrombotic events. Numerous evidence shows that thromboxane A2 receptor (TXA2 receptor, encoded by TBXA2R), lipoprotein-associated phospholipase A2 (Lp-PLA2, encoded by PLA2G7) and platelet endothelial aggregation receptor-1 (PEAR1, encoded by PEAR1) are crucial in regulating platelet activation, and P-glycoprotein (P-gp, encoded by MDR1) influences the absorption of aspirin in the intestine...

BACKGROUND: Inflammation and hypercholesterolaemia contribute to atherosclerotic changes which can start in childhood. Children with hyperlipidaemias are at high risk for early coronary atherosclerosis. This study evaluates the relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2), carotid intima-media thickness (CIMT) and flow-mediated dilatation in hypercholesterolaemic dyslipidaemic children. METHODS: We performed a case-control study consisting of 43 cases, aged 2 to 17 years, and 24 age-matched controls...
