Chronic inflammation and cardiovascular disease

BACKGROUND: Cardiovascular diseases (CVDs) are the leading global cause of death, with atherosclerosis as the primary cause. Chronic inflammation, endothelial dysfunction, and the role of molecules like nitric oxide and reactive oxygen species are crucial in this context. Our previous research indicated that cilostazol and ginkgo biloba extract could enhance the ability of endothelial cells to dissolve blood clots, but the effects of cilostazol on monocytes remain unexplored. METHOD: This study utilized peripheral blood mononuclear cells from 10 healthy donors, treated ex vivo with cilostazol...

Cardiovascular diseases are the leading cause of death globally, and atherosclerosis is the major contributor to the development and progression of cardiovascular diseases. Immune responses have a central role in the pathogenesis of atherosclerosis, with the complement system being an acknowledged contributor. Chronic activation of liver-derived and serum-circulating canonical complement sustains endothelial inflammation and innate immune cell activation, and deposition of complement activation fragments on inflamed endothelial cells is a hallmark of atherosclerotic plaques...

INTRODUCTION: HSP is arguably the most thoroughly studied self-antigens connected to Cardio Vascular Diseases (CVD) and periodontal disease. Hence, the major goal of this analysis was to determine the amount of HSP60 in patients' Chronic Periodontitis (CP) patients' serum. MATERIALS AND METHODS: The current investigation involved 100 patients in all. Based on the patients' periodontal and cardiovascular health, the patients were divided. The patients were made aware that this research had no direct bearing on disease treatment or cure...

Ischemic colitis is a disease in which local tissue in the intestinal wall dies to varying degrees due to insufficient blood supply to the colon. Risk factors include cardiovascular disease, diabetes, chronic kidney disease, chronic obstructive pulmonary disease, etc . Typical clinical manifestations of the disease are abdominal pain and hematochezia. The most common locations are the watershed areas of splenic flexure and rectosigmoid junction. The lesions are segmental and clearly demarcated from normal mucosa under endoscopy...

OBJECTIVES: Growth differentiation factor 15 (GDF-15) levels increase due to systemic inflammation and chronic disease burden. Since these biological processes are pathogenic factors of malnutrition, we examined the prospective association between GDF-15 serum levels and subsequent malnutrition in older adults. METHODS: We used data from 723 women and 735 men aged ≥65 years [mean age (SD): 71.3 (4.18) years] participating in the Seniors-ENRICA-2 cohort, who were followed-up for 2...

OBJECTIVES: Type 1 diabetes mellitus is considered a state of chronic low-grade inflammation and activation of the innate immune system, which is regulated by several proinflammatory cytokines and other acute-phase reactants. Arterial stiffness, a dynamic property of the vessels evaluated by the determination of pulse wave velocity (PWV), is increased in diabetic patients and is associated with microvascular and macrovascular complications of diabetes and higher cardiovascular risk. In the present study, we aimed to compare the proinflammatory state and arterial stiffness in diabetic and non-diabetic adolescents, and to characterize the association between these two parameters...

Background: Inflammation plays a pivotal role in the pathogenesis of both acute and chronic heart failure. Recent studies showed that the neutrophil-to-lymphocyte ratio (NLR) could be related to adverse outcomes in patients with cardiovascular diseases. We sought to evaluate whether NLR could predict mortality in patients with acute heart failure by means of a meta-analysis. Methods: A comprehensive literature search was performed in PubMed, Embase, and Cochrane databases through January 2023 for studies evaluating the association of NLR with mortality in patients with acute heart failure...

Chronic intermittent hypoxia (CIH) is a prevalent condition characterized by recurrent episodes of oxygen deprivation, linked to respiratory and neurological disorders. Prolonged CIH is known to have adverse effects, including endothelial dysfunction, chronic inflammation, oxidative stress, and impaired neuronal function. These factors can contribute to serious comorbidities, including metabolic disorders and cardiovascular diseases. To investigate the molecular impact of CIH, we examined male C57BL/6J mice exposed to CIH for 21 days, comparing to normoxic controls...

BACKGROUND: Horseshoe lung is a rare congenital malformation in which the lung protrudes from the mediastinum to the other side. Owing to the high frequency of other fatal cardiovascular complications, it is often diagnosed in childhood and rarely unnoted until adulthood. We report a case of horseshoe lung in an older patient who underwent thoracotomy. CASE PRESENTATION: The patient was a 69-year-old man with chronic obstructive pulmonary disease (COPD) and a history of heavy smoking...

BACKGROUND: The prevalence of iron deficiency in patients with COPD varies in previous studies. We aimed to assess its prevalence according to three well-known criteria for iron deficiency, its associations with clinical characteristics of COPD and mortality. METHODS: In a cohort study consisting of 84 COPD patients, of which 21 had chronic respiratory failure, and 59 non-COPD controls, ferritin, TSat and mortality across 6.5 years were assessed. Associations between clinical characteristics and iron deficiency were examined by logistic regression, while associations with mortality were assessed in mixed effects Cox regression analyses...

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem inflammation and is a common cause of pericarditis and pericardial effusion, but significant pericardial effusion and cardiac tamponade are rare and even rarer as the first manifestation. CASE SUMMARY: We report the case of a young male who presented with fever, recurrent pericarditis, and polyserositis with pericardial and bilateral pleural effusion. On examination, he was haemodynamically unstable and the pericardial effusion had considerable dimensions and an urgent pericardiocentesis was performed...

Recent updates in research highlight its multifaceted pharmacological properties, demonstrating anti-inflammatory, antioxidant, and anticancer effects. With a rich history in traditional medicine, nimbolide efficacy in addressing the molecular complexities of conditions such as cardiovascular diseases, diabetes, and cancer positions it as a promising candidate for further exploration...

Prediabetes increases the risk of type 2 diabetes, metabolic syndrome, chronic renal disease, and cardiovascular disease in a person. In current practice, five alternative definitions of prediabetes are utilized, each based on different HbA1C, fasting glucose, and 2-hour glucose cut points. Prediabetes is a common condition that occurs between normal glycemia and diabetes. It is more common in elderly and obese people. The prevalence of prediabetes and diabetes can be influenced by a variety of individual, family, and societal variables...

The high prevalence of metabolic syndrome is threatening the health of populations all over the world. Contemporary work demonstrates that high leptin concentration is directly related to the development of metabolic syndrome such as obesity, fatty liver diseases, type 2 diabetes mellitus and cardiovascular diseases. Anthocyanins are a widespread group of dietary polyphenols, which can ameliorate chronic diseases related to metabolic syndrome. In addition, anthocyanins can regulate the leptin pathway in chronic metabolic diseases, however the potential mechanism between anthocyanin and leptin is complex and elusive...

BACKGROUND: Atherosclerosis (AS) is an important cause of cardiovascular disease, posing a substantial health risk. Recognized as a chronic inflammatory disorder, AS hinges on the pivotal involvement of macrophages in arterial inflammation, participating in its formation and progression. Sangzhi alkaloid (SZ-A) is a novel natural alkaloid extracted from the mulberry branches, has extensive pharmacological effects and stable pharmacokinetic characteristics. However, the effects and mechanisms of SZ-A on AS remain unclear...

INTRODUCTION: Obesity, prevalent in approximately 80% of Qatar's adult population, increases the risk of complications like type 2 diabetes and cardiovascular diseases. Predictive biomarkers are crucial for preventive strategies. Salivary α-amylase activity (sAAa) inversely correlates with obesity and insulin resistance in adults and children. However, the connection between sAAa and cardiometabolic risk factors or chronic low-grade inflammation markers remains unclear. This study explores the association between serum sAAa and adiposity markers related to cardiovascular diseases, as well as markers indicative of chronic low-grade inflammation...

Uric acid is a product of purine degradation, and uric acid may have multiple physiologic roles, including the beneficial effects as an antioxidant and neuroprotector, maintenance of blood pressure during low salt ingestion, and modulation of immunity. However, overproduction of metabolic uric acid, and/or imbalance of renal uric acid secretion and reabsorption, and/or underexcretion of extrarenal uric acid, e.g. gut, will contribute to hyperuricemia, which is a common metabolic disease. Long-lasting hyperuricemia can induce the formation and deposition of monosodium urate (MSU) crystals within the joints and periarticular structures...

Chronic systemic inflammation contributes to a substantially elevated risk of myocardial infarction in people living with HIV (PLWH). Endothelial cell dysfunction disrupts vascular homeostasis regulation, increasing the risk of vasoconstriction, inflammation, and thrombosis that contribute to cardiovascular disease. Our objective was to study the effects of plasma from PLWH on endothelial cell (EC) function, with the hypothesis that cytokines and chemokines are major drivers of EC activation. We first broadly phenotyped chemokine and cytokine receptor expression on arterial ECs, capillary ECs, venous ECs, and vascular smooth muscle cells (VSMCs) in adipose tissue in the subcutaneous adipose tissue of 59 PLWH using single cell transcriptomic analysis...

Inflammatory bowel disease (IBD) presents a complex interplay of chronic inflammation in the gastrointestinal tract and is associated with various extraintestinal manifestations, including cardiovascular complications (CVCs). IBD patients face an elevated risk of CVCs, including coronary artery disease, heart failure, arrhythmias, stroke, peripheral artery disease, venous thromboembolism, and mesenteric ischemia, necessitating comprehensive cardiovascular risk assessment and management. The intricate interplay between chronic inflammation, genetic predisposition, environmental factors, and immune dysregulation likely contributes to the development of CVCs in IBD patients...

INTRODUCTION: Habitual betel quid chewing, a tobacco product, is a leading cause of oral cancer in Asia-Pacific countries where this practice is most prevalent. However, it is not well understood whether betel quid chewing is also a cause of adverse cardiovascular outcomes. To address this gap, we conducted a systematic literature review of peer-reviewed published studies evaluating the association between habitual betel quid use on the risk of adverse cardiovascular outcomes. METHODS: We searched PubMed for studies assessing the correlation between betel quid chewing and cardiovascular health...
