Immune-inflammatory markers and arterial stiffness indexes in subjects with acute ischemic stroke.
2010
Abstract No study has yet evaluated the relationship between arterial stiffness indexes and immuno-inflammatory pathway in patients with an acute cardiovascular or cerebrovascular event. The aim of our study was to evaluate in patients with acute ischemic stroke the relationship between immune-inflammatory markers and arterial stiffness indexes. Methods 107 subjects with acute ischemic stroke and 107 controls without stroke. We evaluated plasma levels of C-reactive protein (CRP), interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10), E-selectin, P-selectin, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1…
Hypertension and diabetes mellitus are associated with cardiovascular events in the elderly without cardiovascular disease. Results of a 15-year foll…
2009
Abstract Background and aims Epidemiological prospective data on cardiovascular (CV) events in elderly subjects from Mediterranean populations are lacking. We aimed to investigate 15-year incidence of CV events and to evaluate the association with CV risk factors in an elderly Mediterranean population. Methods and results The population of a small Sicilian village were enrolled, visited and a blood sample was drawn at baseline. CV events were recorded in the 15 years of follow-up. From 1351 subjects (75% of the resident population); 315 were in the age range 65–85 years; 266 subjects free from CV disease were analysed. Seventy-seven CV events were recorded in 73 out of 266 subjects, with a …
The predictive role of C-reactive protein in patients with hypertension and subclinical atherosclerosis.
2009
Recent guidelines published by the joint European Society of Hypertension/European Society of Cardiology have suggested the inclusion of C-reactive protein (CRP) in the standard assessment of cardiovascular risk in hypertensive patients, but little data is available on the role of CRP in patients with carotid lesions. We studied in 472 subjects, 236 with and 236 without hypertension, gender- and age-matched, with and without early stages of atherosclerosis (e.g. those with asymptomatic intima-media thickness >0.9 mm), the influence of all the other traditional cardiovascular risk factors (e.g. older age, male gender, obesity, diabetes, smoking habit, family history of coronary artery diseas…
Skin Sodium Accumulates in Psoriasis and Reflects Disease Severity
2020
Sodium can accumulate in the skin at concentrations exceeding serum levels. A high sodium environment can lead to pathogenic T helper 17 cell expansion. Psoriasis is a chronic inflammatory skin disease in which IL-17. producing T helper 17 cells play a crucial role. In an observational study, we measured skin sodium content in patients with psoriasis and in age-matched healthy controls by Sodium-23 magnetic resonance imaging. Patients with PASI > 5 showed significantly higher sodium and water content in the skin but not in other tissues than those with lower PASI or healthy controls. Skin sodium concentrations measured by Sodium-23 spectroscopy or by atomic absorption spectrometry in ashed-…
Influence of HMG-CoA reductase inhibitors on markers of coagulation, systemic inflammation and soluble cell adhesion.
2002
Abstract Background: Beneath its lipid-lowering properties additional non-lipid effects of statin therapy are discussed. We therefore examined the impact of statins on laboratory markers of coagulation, inflammation and soluble cell adhesion to further explore these effects in 950 hospitalised patients with angiographically proven CAD. Methods and results: Although no significant differences were found in total cholesterol, LDL and HDL and triglyceride levels a statistically lower value in 277 statin-treated patients was found for von Willebrand factor [162(130/224) vs. 208(154/283)%, P =0.0001], leukocyte count [6.9(5.8/8.4) vs. 7.3(6.1/9.4)/nl, P =0.0005], high sensitive CRP [4.3(1.8/10.8…
Assessment of heart rate variability (HRV) in subjects with type 2 diabetes mellitus with and without diabetic foot: correlations with endothelial dy…
2021
Abstract Background Some studies have suggested that patients with diabetes and foot complications have worse cardiovascular and cerebrovascular risk profiles, higher degrees of endothelial dysfunction and arterial stiffness and a higher inflammatory background than patients with diabetes without diabetic foot complications. Patients with diabetes mellitus have an alteration in the sympathovagal balance as assessed by means of heart rate variability (HRV) analysis, which is also related to the presence of endothelial dysfunction. Other studies suggest a possible role of inflammation coexisting with the alteration in the sympathovagal balance in favor of the atherosclerotic process in a mixe…
Insulin resistance as common molecular denominator linking obesity to Alzheimer’s disease
2015
Alzheimer’s disease (AD) is an aging-related multi-factorial disorder to which metabolic factors contribute at what has canonically been considered a centrally mediated process. Although the exact underlying mechanisms are still unknown, obesity is recognized as a risk factor for AD and the condition of insulin resistance seems to be the link between the two pathologies. Using mice with high fat diet (HFD) obesity we dissected the molecular mechanisms shared by the two disorders. Brains of HFD fed mice showed elevated levels of APP and Aβ 40 /Aβ 42 together with BACE, GSK3β and Tau proteins involved in APP processing and Aβ accumulation. Immunofluorescence, Thioflavin T staining experiments…
Immunoinflammatory activation during the acute phase of lacunar and non-lacunar ischemic stroke: Association with time of onset and diabetic state
2006
Several studies have stressed the involvement of inflammation in the pathophysiology of acute brain ischemia, but the role of immunoinflammatory activation in diabetic stroke patients has not yet been fully evaluated. The aim of our study was to evaluate immunoinflammatory activation of acute phase of stroke in relation to time of symptoms onset, diabetic state and diagnostic subtype. We enrolled 60 patients (32 diabetics; 28 non- diabetics) with acute ischemic stroke and 123 subjects without acute ischemic stroke, and measured levels of IL-1β, TNF-α, IL-6, IL-10, E-selectin, P-selectin, sICAM-1, sVCAM-1, VWF, 24–72 h and 7–10 days after stroke onset; TPA, PAI-1 plasma levels at 24–72h. Ou…
Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality
2005
Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…
Exercise-induced necrotic muscle damage and enzyme release in the four days following prolonged submaximal running in rats.
1994
Male Wistar rats were made to run uphill on a treadmill 5.5° incline at 17 m min−1 for 4 h, and killed for muscle and serum sampling 2, 4, 12, 24, 48 or 96 h after the exertion. To estimate the degree of muscle damage,β-glucuronidase activity, total protein concentration, water content and morphology were examined in the red parts of quadriceps femoris (MQF) and soleus (MS) muscles, the distal white part of the rectus femoris muscle (MRF) and the superficial part of triceps brachii muscle (MTB). Simultaneous serum samples were assayed for creatine kinase (CK) activity and carbonic anhydrase III (CA III) concentration. Fibre swelling and interstitial oedema were detected in MS at 4 h and in …
