These findings indicate the important roles that TNF-α and IL-1β serum levels play regarding the risk of PSD, particularly during the acute phase of stroke and in patients with genetic susceptibility.
Randomized, active controlled parallel group trials were included if they compared CCBs with α-blockers, β-blockers, angiotensin II receptor blockers, angiotensin-converting enzyme inhibitors, or diuretics, had a follow-up of ≥6 months, and had assessments of blood pressure (BP) and CV events [all-cause death, CV death, major CV events (myocardial infarction, MI; congestive heart failure, CHF; stroke; and CV death), MI, stroke, or CHF] in patients with baseline systolic/diastolic BP ≥140/≥90 mm Hg with either concomitant previous stroke and/or CAD.
Stroke survivors (50-76 years) underwent a fasting blood draw for measurement of TNF-α, IL-6, CRP, serum amyloid A, sICAM-1, sVCAM-1, and bilateral vastus lateralis biopsies before and after RT.
Serum levels of TNF-α, C-reactive protein (CRP), IL-4, IL-6, IL-10, IL-17, IL-23, and TGF-β increased, whereas serum level of IFN-γ decreased at all time points after stroke.
This study suggests that delirium is not scarce in patients with AIS admitted to the non-intensive stroke unit, and that delirium developing after AIS seems not to be associated with serum TNF-alpha, IL-1 beta, IL-18, BDNF and NSE but is associated with length of hospital stay and stroke severity.
Quantitative PCR analysis of whole cell lysate as well as flow-sorted myeloid cells from the perilesional cortex showed increased cellular interleukin 1 beta (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) mRNA levels but reduced plasma levels of these cytokines in MS P2X4R KO mice after stroke.
We demonstrate that therapeutic approaches targeting synergistic IL-17 and tumor necrosis factor-α pathways in parallel offer additional neuroprotection in stroke.
Angiotensin I converting enzyme (ACE) insertion/deletion (I/D) polymorphism is thought to affect renin-angiotensin system (RAS) activity and development of cardiovascular disease; significant associations between I/D polymorphism and atherosclerosis, stroke, nephropathy, and early mortality were already found.
Tumor necrosis factor (TNF) has been shown to be involved in the pathogenesis of hemorrhagic stroke, having deleterious effects on cerebral arteries by promoting inflammation and apoptosis in vascular and immune cells.
Furthermore, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and statins were of statistical significance for stroke risks.The majority of AF patients post-RFAs was of high stroke risk and received warfarin thromboprophylaxis in accordance with national guidelines.
In pharmacogenetic analysis, the increased risk of stroke in subjects carrying G-6 was eliminated by concomitant treatment with an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker (P = .012 for interaction).
Polymorphic variants in genes encoding apoptotic proteins, either from the extrinsic (FAS, TNF-α, CASP8) or the intrinsic (BAX, BCL2, CASP3, CASP9) pathways could be highly valuable in the diagnosis of neurodegenerative diseases and stroke.
Up-regulated TNF-α expression has also been found in various neurodegenerative diseases such as cerebral malaria, AIDS dementia, Alzheimer's disease, multiple sclerosis, and stroke, suggesting a potential pathogenic role of TNF-α in these diseases as well.
The aim of this study was to evaluate the association of genetic variants within the genes encoding tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-3 (MMP-3), with stroke.
We investigated the role of inflammatory genes IL1B, IL6, MPO, and TNF in stroke susceptibility and recovery in a population sample of 672 patients and 530 controls, adjusting for demographic, clinical and lifestyle risk factors, and stroke severity parameters.
The effects of AT1 receptor blocker, telmisartan, and the ACE inhibitor, ramipril, were tested head-to head and in combination on stroke prevention in hypertensive rats and on potential neuroprotection in acute cerebral ischemia in normotensive rats.
