Prognostic value of lipoproteins and their relation to inflammatory markers among patients with coronary artery disease
2005
Abstract Background Lipoproteins and their subfractions are associated with the incidence of atherosclerotic diseases. In patients with coronary artery disease (CAD), low serum concentrations of high density lipoprotein (HDL) and high low-density lipoproteins (LDL) are correlated to myocardial infarction and cardiovascular death. There is growing evidence indicating that those lipoprotein factors are related to the inflammatory process in atherogenesis. Methods We investigated in a median follow up of 3.9 years the association of HDL, apolipoprotein A-I (apoA-I), LDL, apolipoprotein B (apoB), and triglycerides with the incidence of a combined endpoint (myocardial infarction and cardiovascul…
Women and peripheral arterial disease: same disease, different issues
2008
Objectives Atherosclerosis is a multifactorial disease and, thus, its clinical manifestations are likely to present gender-specific differences with respect to their development, course, symptom complexes and prognosis. The present study aimed to examine sex differences in peripheral arterial disease (PAD) and its clinical correlates. Methods PAD severity, quality of life (assessed by ST-22), cardiovascular risk factors, inflammatory profile and comorbidity were assessed in 163 men and 68 women who were consecutively diagnosed with PAD at three Italian University vascular centres. Results Compared to men, women showed a higher prevalence of critical limb ischemia (P = 0.018), but had a less…
Heat shock protein 70 in patients with chronic heart failure: relation to disease severity and survival
2004
Heat shock protein 70 (Hsp70) is essential for cellular recovery, survival and maintenance of cellular function. Research into the possible use of Hsp70 as a cytoprotective therapeutic agent is ongoing. Chronic heart failure (CHF) is a state associated with systemic inflammation, particularly in patients with cardiac cachexia. We hypothesised that circulating Hsp70 levels are elevated in patients with CHF, more so in cachechtic patients, and that Hsp70 levels would relate to mortality.We studied 107 patients (28 female, age 67+/-1 years, NYHA class 2.6+/-0.6 and LVEF 29+/-1%, mean+/-SEM) and 21 controls. Cardiac cachexia was present in 32 patients. Hsp70 was detectable in 41% of CHF patient…
Adipocyte cannabinoid CB1 receptor deficiency alleviates high fat diet-induced memory deficit, depressive-like behavior, neuroinflammation and impair…
2019
Abstract Background Obesity is a low-grade inflammation condition that facilitates the development of numerous comorbidities and the dysregulation of brain homeostasis. Additionally, obesity also causes distinct behavioral alterations both in humans and rodents. Here, we investigated the effect of inducible genetic deletion of the cannabinoid type 1 receptor (CB1) in adipocytes (Ati-CB1-KO mice) on obesity-induced memory deficits, depressive-like behavior, neuroinflammation and adult neurogenesis. Methods Behavioral, mRNA expression and immunohistochemical studies were performed in Ati-CB1-KO mice and corresponding wild-type controls under standard and high-fat diet. Results Adipocyte-speci…
Effects of levosimendan on hemodynamics, local cerebral blood flow, neuronal injury, and neuroinflammation after asphyctic cardiac arrest in rats.
2014
Despite advances in cardiac arrest treatment, high mortality and morbidity rates after successful cardiopulmonary resuscitation are still a major clinical relevant problem. The post cardiac arrest syndrome subsumes myocardial dysfunction, impaired microcirculation, systemic inflammatory response, and neurological impairment. The calcium-sensitizer levosimendan was able to improve myocardial function and initial resuscitation success after experimental cardiac arrest/cardiopulmonary resuscitation. We hypothesized that levosimendan exerts beneficial effects on cerebral blood flow, neuronal injury, neurological outcome, and inflammation 24 hours after experimental cardiac arrest/cardiopulmonar…
Inflammation-induced upregulation of NK1 receptor mRNA in dorsal horn neurones
1993
The expression of the neurokinin 1 (NK1) receptor (i.e. substance P receptor) gene in spinal cord was studied in rats subjected to unilateral inflammation by semi-quantitative in situ hybridization analysis. Low levels of NK1 receptor mRNA were detected in many neurones throughout the grey matter. Relatively strong labelling was observed in large motoneurones and a subpopulation of superficial dorsal horn neurones. Six days after Freund's adjuvant-induced unilateral hindpaw inflammation, NK1 receptor mRNA levels in lamina I/II of the dorsal horn ipsilateral to the inflamed paw increased almost two fold compared with the contralateral side. These data suggest an inflammation-induced increase…
CXCR2 blockade impairs angiotensin II-induced CC chemokine synthesis and mononuclear leukocyte infiltration.
2007
Objective—Angiotensin II (Ang-II) and mononuclear leukocytes are involved in atherosclerosis. This study reports the inhibition of Ang-II–induced mononuclear cell recruitment by CXCR2 antagonism and the mechanisms involved.Methods and Results—Ang-II (1 nmol/L, i.p. in rats) induced CXC and CC chemokines, followed by neutrophil and mononuclear cell recruitment. Administration of the CXCR2 antagonist, SB-517785-M, inhibited the infiltration of both neutrophils (98%) and mononuclear cells (60%). SB-517785-M had no effect on the increase in CXC chemokine levels but reduced MCP-1, RANTES, and MIP-1α release by 66%, 63%, and 80%, respectively. Intravital microscopy showed that pretreatment with S…
Cytokine expression in tears of patients with glaucoma or dry eye disease: A prospective, observational cohort study.
2018
Background: The aim of this study was to assess the expression of cytokines/chemokines in tears from patients with non-advanced primary open-angle glaucoma and patients with non-severe dry eye disease versus healthy controls. Methods: This prospective, observational cohort study enrolled patients with confirmed or suspected non-advanced primary open-angle glaucoma who received any prostaglandin analogue monotherapy for longer than 6 months, patients with non-severe dry eye disease, and healthy controls. Expression of interleukin-1β, interleukin-2, interleukin-4, interleukin-5, interleukin-6, interleukin-8, interleukin-10, and interleukin-12; tumor necrosis factor α; vascular endothelial gro…
When GLP-1 hits the liver: a novel approach for insulin resistance and NASH
2012
nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum ranging from simple steatosis to steatohepatitis (NASH), increasing fibrosis and eventually, cirrhosis ([22][1]). Importantly, NASH accompanied by fibrosis and severe inflammation is the most relevant predictor for disease progression
Cytomegalovirus infection with interleukin-6 response predicts cardiac mortality in patients with coronary artery disease.
2001
Background —Prospective data relating previous exposure to cytomegalovirus (CMV) to the risk of cardiac mortality are controversial. We investigated the effect of previous exposure to CMV infection on the risk of future cardiac disease–related death in relation to an underlying inflammatory response. Methods and Results —Coronary angiography was performed in 1134 subjects, and 989 patients with documented coronary artery disease were studied prospectively. CMV-IgG titers and interleukin (IL)-6 levels were measured before angiography. Increasing titers of CMV correlated with the elevation of IL-6 levels ( P <0.001) after adjustment for possible confounders. All patients were followed up …
