Changes in serum fetuin-A and inflammatory markers levels in end-stage renal disease (ESRD): effect of a single session haemodialysis.

2007

Background: The aim of the present study was to evaluate the effect of a single haemodialysis (HD) session on serum fetuin-A levels, considered a negative acute phase response marker; moreover, we evaluated the behaviour of fibrinogen and high sensitivity C-reactive protein (hsCRP) as acute phase response and chronic/subclinical inflammation markers, respectively, after a single HD session. Methods: Serum fetuin-A, albumin, hsCRP and fibrinogen were measured in 72 patients before and after a single HD session. Results: After a single HD session, we observed a significant increase in fibrinogen levels, while fetuin-A levels decreased (p<0.05). Also, hsCRP levels were significantly increased.…

CONCLUSIONS: A significant association was noted between the severity of neurological deficit at admission, the diagnostic subtype and so…

INFLAMMATORY CYTOKINES IN ACUTE ISCHEMIC STROKE.

2008

Three major cytokines, namely, tumor necrosis factor (TNF-alpha), interleukin (IL)-1, and IL-6 are produced by cultured brain cells after various stimuli such as ischemia. Neurones, astrocytes, microglia and oligodendrocytes can produce inflammatory mediators, and cytokine receptors are expressed constitutionally throughout the Central Nervous System (CNS), albeit at low levels. Cytokines are involved in virtually every facet of stroke and they have numerous pro-inflammatory and pro-coagulant effects on endothelium. TNF-alpha expression after stroke stimulates expression of tissue factor and adhesion molecules for leukocytes, release of interleukin-1 (IL-1), nitric oxide, factor VIII/von Wi…

Antiplatelet treatment in ischemic stroke treatment.

2009

Antiplatelets represent a diverse group of agents that share the ability to reduce platelet activity through a variety of mechanisms. Antithrombotic agents are effective in the secondary prevention of ischemic strokes. Most strokes are caused by a sudden blockage of an artery in the brain (called an ischaemic stroke) that is usually due to a blood clot. Immediate treatment with antiplatelet drugs such as aspirin may prevent new clots from forming and hence improve recovery after stroke. Several studies have evaluated the role of one antiplatelet agent, aspirin, in reducing stroke severity. The International Stroke Trial (IST) of 20,000 patients with acute stroke from other countries. In thi…

Inflammation as a therapeutic target in acute ischemic stroke treatment.

2009

Animal models of focal ischaemia induced by middle cerebral artery occlusion (MCAO) provide most evidence for cellular inflammatory responses in stroke. Permanent MCAO results in a modest neutrophil infiltration at 24 h after ischaemia, predominantly around arterial vessels at the margins of infarction, whereas MCAO with subsequent reperfusion is associated with substantial infiltration by neutrophils throughout the entire infarct. Several studies show that C-reactive protein (CRP), an inflammatory marker, is associated with stroke outcomes and future vascular events. Several drugs, especially hydroxymethylglutaryl coenzyme A reductase inhibitors (statins), have been demonstrated to reduce …

Diabetic and non-diabetic subjects with ischemic stroke: Differences, subtype distribution and outcome

2008

Abstract Background and aim Diabetes mellitus increases the risk of stroke, and pathophysiological changes of diabetic cerebral vessels may differ in comparison with non-diabetic ones; nonetheless, the clinical and prognostic profile of stroke in diabetic patients is not yet fully understood. On this basis, the aim of our study was to evaluate cerebrovascular risk factor prevalence in diabetic stroke patients in comparison with non-diabetics, to analyze whether diabetics have a different prevalence of stroke subtypes as classified by the TOAST classification, and determine whether diabetics and non-diabetics have a different prognosis. Methods and results We enrolled 102 diabetics and 204 n…

Arterial stiffness and ischemic stroke in subjects with and without metabolic syndrome.

2012

We conducted a study to evaluate arterial stiffness markers in subjects with acute ischemic stroke and metabolic syndrome and in relation to TOAST subtype of stroke. We enrolled 130 patients with acute ischemic stroke and metabolic syndrome, 127 patients with acute ischemic stroke without metabolic syndrome and 120 control subjects without acute stroke. Applanation tonometry to record pulse wave velocity (PWV). Stroke patients with metabolic syndrome, compared control subjects without stroke showed higher PWV. In subjects with ischemic stroke and metabolic syndrome, PWV was more significantly and positively correlated with body mass index, systolic blood pressure, hypertension, diabetes, gl…

Predictors of outcome in acute ischemic cerebrovascular syndromes: The GIFA study

2006

Abstract Background Today it may be more useful to use the term acute ischemic cerebrovascular syndrome (AICS) to define a spectrum of disease ranging from TIA to stroke and that share a similar underlying pathophysiology: cerebral ischemia . The aim of this study is to evaluate the prognostic importance of some demographic, laboratory and clinical variables on the outcome in hospitalized patients with a discharge diagnosis suggestive of acute ischemic cerebral syndrome (AICS). Methods 17,377 Subjects were enrolled in the GIFA study, a multicenter survey of hospitalized older patients. 1878 Subjects with a main discharge diagnosis suggestive of acute ischemic cerebrovascular syndrome (AICS)…

The aim of our study was to evaluate arterial stiffness indexes in subjects with acute ischemic stroke and to evaluate the relationship between these indexes and other clinical and laboratory variables. MATERIALS AND METHODS: We enrolled all consecutive patients with a diagnosis of acute ischemic stroke admitted to the Internal Medicine Department at the University of Palermo between November 2006 and January 2009, and hospitalized control patients without a diagnosis of acute ischemic stroke. The type of acute ischemic stroke was classified according to the TO…

Immuno-inflammatory predictors of stroke at follow-up in patients with chronic non-valvular atrial fibrillation (NVAF).

2009

Accumulating evidence suggests that inflammation plays an important role in the acute phase of ischemic stroke. CD40 L is a well recognized atherosclerotic inflammatory marker, whereas recent evidence suggests a pro-inflammatory role of Fetuin-A. To analyze the role of an inflammatory marker such as CD40 L and of a candidate pro-inflammatory marker such as Fetuin-A in acute stroke we evaluated their serum levels in subjects with acute ischemic stroke and their possible association with other laboratory and clinical variables. MATERIALS AND METHODS: We enrolled 107 consecutive patients with a diagnosis of acute ischemic stroke admitted to the Internal Medicine Department at the University of…
