We demonstrate that therapeutic approaches targeting synergistic IL-17 and tumor necrosis factor-α pathways in parallel offer additional neuroprotection in stroke.
The ACE D allele prevalence was also greater among patients reporting a parental history of stroke incidence before age 65 years (0.66 versus 0.57, P = 0.05).
Dual RAAS blockade with angiotensin-converting enzyme (ACE) inhibitor plus angiotensin receptor blockade (ARB) or ARB plus renin inhibition increases serious adverse events such as acute kidney injury and stroke.
The Objective of this research was to study the relationship of angiotensin converting enzyme (ACE) genotype with serum triglycerides concentration in stroke patients.
Patients with first-in-life stroke were analysed according to: plasma concentration of the following markers on the first day of stroke: interleukin 2 (IL-2) and interleuki 6 (IL-6), S100B, tumor necrosis factor-α (TNF-α), progranulin (GRN), neuron specific enolase (NSE), urokinase-type plasminogen activator (uPA), vascular endothelial growth factor (VEGF), brain-derived neurotrophic factor (BDNF), C-reactive protein (CRP), leucocyte and thrombocyte counts; their neurological status on the first day of stroke (NIHSS) and their functional status at 30 days following stroke (mRS).
The sensitivity analysis (exclusion of studies with controls not in Hardy-Weinberg equilibrium) revealed a significant association of stroke with the MTHFR C677T and ApoE epsilon 4 alleles but showed no association with ACE gene insertion/deletion polymorphism.
We investigated whether gradual increases in tumor necrosis factor-alpha (TNF-alpha) reported during exercise down-regulates expression of TNF-alpha receptors I and II (TNFRI and II) in stroke, leading to reduced brain damage.
We also subjected TNF knockout mice to experimental stroke (permanent middle cerebral artery occlusion) and validated the effect of TNF inhibition on EV release.
The effects of statins, acetylsalicyclic acid and angiotensin-converting enzyme inhibitors on stroke prevention may partly be attributable to their profound anti-inflammatory actions.
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.
The polymorphism of the angiotensin-converting enzyme gene is considered to be associated with increased risk for stroke, but there is a diversity in the results obtained.
We conducted analyses of the effects of ACE inhibitor therapy on pneumonia in 6,105 patients with a history of stroke or transient ischemic attack enrolled in a randomized trial conducted in Australasia, Europe, and Asia.
We administered the National Adult Reading Test (NART, estimates premorbid or peak adult cognition) and the Revised Addenbrooke's Cognitive Examination (ACE-R; current cognition) at 1 and 12 months after stroke.
We mainly observed a reduced risk of recurrent stroke in the subgroup of participants using an angiotensin-converting enzyme (ACE) inhibitor or a diuretic (I<sup>2</sup> statistic for subgroup differences 72.1%; P = 0.006).
We also performed functional studies by measuring serum ACE protein levels and enzymatic activity in 27 controls, 68 patients with IS at baseline and 35 patients with IS 24 h after onset of stroke symptoms.
The angiotensin converting enzyme (ACE) gene is a candidate gene for two phenotypically different types of stroke affecting small perforating arteries: spontaneous intracerebral hemorrhage (SIH) and ischemic stroke due to small vessel disease (SVD).
Most estimates revealed no effectiveness differences between classes; however, thiazide or thiazide-like diuretics showed better primary effectiveness than angiotensin-converting enzyme inhibitors: acute myocardial infarction (HR 0·84, 95% CI 0·75-0·95), hospitalisation for heart failure (0·83, 0·74-0·95), and stroke (0·83, 0·74-0·95) risk while on initial treatment.
Compared with nonuse, ACE inhibitor use was associated with lower stroke risk among Thr homozygotes (odds ratio [OR] = 0.37, 95% CI = 0.14 to 0.99) than among Met carriers (OR = 1.4, 95% CI = 0.88 to 2.4; P for interaction =.02).
