Prognostic significance of plasma SDF-1 in acute ischemic stroke patients with diabetes mellitus: the CATIS trial.

ABSTRACT:

Background and objectives

Evidence on the associations between baseline stromal cell-derived factor (SDF)-1 and clinical outcomes in acute ischemic stroke patients is lacking. The present study aimed to examine the relationship between plasma SDF-1 levels and clinical outcomes based on a large multicenter study of the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS).

Methods

Secondary analysis was conducted among 3,255 participants from the CATIS trial with a baseline measurement of plasma SDF-1 levels. We evaluated the associations between plasma SDF-1 levels and one-year recurrent stroke, cardiovascular events, and all-cause mortality using Cox regression models. We further investigated the prognostic effect of SDF-1 on clinical outcomes in patients with different characteristics.

Results

Higher plasma SDF-1 levels were not associated with recurrent stroke, cardiovascular events, and all-cause mortality at one-year after ischemic stroke (all P trend ≥ 0.05). There were significant interactions between plasma SDF-1 levels and history of diabetes mellitus on recurrent stroke (P = 0.005), cardiovascular events (P = 0.007) and all-cause mortality (P = 0.04) at one year. In patients with diabetes mellitus, plasma SDF-1 was significantly associated with an increased risk of recurrent stroke and cardiovascular events after adjustment for confounders. For example, 1-SD higher log-SDF-1 was associated with a hazard ratio (95% confidence interval) of 1.65 (1.18-2.32) for recurrent stroke and 1.47 (1.08-1.99) for the cardiovascular events, but not all-cause mortality 1.36 (0.96-1.93) at one year. However, there were no associations between plasma SDF-1 and clinical outcomes in patients without diabetes mellitus (all P > 0.05). The addition of plasma SDF-1 to the conventional risk factors model significantly improved the risk prediction of all outcomes. Similarly, findings between elevated SDF-1 levels and two-year outcomes were found only in patients with diabetes mellitus.

Conclusions

Elevated plasma SDF-1 was significantly associated with an increased risk of recurrent stroke and cardiovascular events only in ischemic patients with diabetes mellitus.

Project description:BackgroundHyperglycemic non-diabetic stroke patients have a worse prognosis than both normoglycemic and diabetic patients. Aim of this study was to assess whether hyperglycemia is an aggravating factor or just an epiphenomenon of most severe strokes.MethodsIn this retrospective study, 1219 ischemic or hemorrhagic stroke patients (73.7 ± 13.1 years) were divided into 4 groups: 0 = non-hyperglycemic non-diabetic, 1 = hyperglycemic non-diabetic, 2 = non-hyperglycemic diabetic and 3 = hyperglycemic diabetic. Hyperglycemia was defined as fasting blood glucose ≥ 126 mg/dl (≥ 7 mmol/l) measured the morning after admission, while the diagnosis of diabetes was based on a history of diabetes mellitus or on a glycated hemoglobin ≥ 6.5% (≥ 48 mmol/mol), independently of blood glucose levels. All diabetic patients, except 3, had Type 2 diabetes. The 4 groups were compared according to clinical history, stroke severity indicators, acute phase markers and main short term stroke outcomes (modified Rankin scale ≥ 3, death, cerebral edema, hemorrhagic transformation of ischemic lesions, fever, oxygen administration, pneumonia, sepsis, urinary infection and heart failure).ResultsGroup 1 patients had more severe strokes, with larger cerebral lesions and higher inflammatory markers, compared to the other groups. They also had a high prevalence of atrial fibrillation, prediabetes, previous stroke and previous arterial revascularizations. In this group, the highest frequencies of cerebral edema, hemorrhagic transformation, pneumonia and oxygen administration were obtained. The prevalence of dependency at discharge and in-hospital mortality were equally high in Group 1 and Group 3. However, in multivariate analyses including stroke severity, cerebral lesion diameter, leukocytes and C-reactive protein, Group 1 was only independently associated with hemorrhagic transformation (OR 2.01, 95% CI 0.99-4.07), while Group 3 was independently associated with mortality (OR 2.19, 95% CI 1.32-3.64) and disability (OR 1.70, 95% CI 1.01-2.88).ConclusionsHyperglycemic non-diabetic stroke patients had a worse prognosis than non-hyperglycemic or diabetic patients, but this group was not independently associated with mortality or disability when size, severity and inflammatory component of the stroke were accounted for.

Project description:Background and Purpose- Acute ischemic stroke patients with history of prior ischemic stroke plus concomitant diabetes mellitus (DM) were excluded from the ECASS III trial (European Cooperative Acute Stroke Study) because of safety concerns. However, there are few data on use of intravenous tissue-type plasminogen activator and symptomatic intracerebral hemorrhage or outcomes in this population. Methods- Using data from the Get With The Guidelines-Stroke Registry between February 2009 and September 2017 (n=1619 hospitals), we examined characteristics and outcomes among patients with acute ischemic stroke treated with tissue-type plasminogen activator within the 3- to 4.5-hour window who had a history of stroke plus diabetes mellitus (HxS+DM) (n=2129) versus those without either history (n=16 690). Results- Compared with patients without either history, those with both prior stroke and DM treated with tissue-type plasminogen activator after an acute ischemic stroke had a higher prevalence of cardiovascular risk factors in addition to history of stroke, DM, and more severe stroke (National Institutes of Health Stroke Scale: median, 8 [interquartile range, 5-15] versus 7 [4-13]). The unadjusted rates of symptomatic intracerebral hemorrhage and in-hospital mortality were 4.3% (HxS+DM) versus 3.8% (without either history; P=0.31) and 6.2% versus 5.5% ( P=0.20), respectively. These differences were not statistically significant after risk adjustment (symptomatic intracerebral hemorrhage: adjusted odds ratio, 0.79 [95% CI, 0.51-1.21]; P=0.28; in-hospital mortality: odds ratio, 0.77 [95% CI, 0.52-1.14]; P=0.19). Unadjusted rate of functional independence (modified Rankin Scale score, 0-2) at discharge was lower in those with HxS+DM (30.9% HxS+DM versus 44.8% without either history; P≤0.0001), and this difference persisted after adjusting for baseline clinical factors (adjusted odds ratio, 0.76 [95% CI, 0.59-0.99]; P=0.04). Conclusions- Among patients with acute ischemic stroke treated with intravenous tissue-type plasminogen activator within the 3- to 4.5-hour window, HxS+DM was not associated with statistically significant increased symptomatic intracerebral hemorrhage or mortality risk.

Project description:BackgroundClinical trials have generally showed a neutral effect of blood pressure (BP) reduction on clinical outcomes among acute ischemic stroke patients. We conducted a prespecified subgroup analysis to assess whether disease severity modifies the effect of early antihypertensive treatment on death and disability among patients with acute ischemic stroke.MethodsIn the China Antihypertensive Trial in Acute Ischemic Stroke, 4,071 patients with acute ischemic stroke and elevated BP were randomly assigned to receive antihypertensive treatment or to discontinue all hypertension medications within 48 h of symptom onset. The primary outcome was a combination of death and major disability at 14 days or hospital discharge. In this subgroup analysis, participants were categorized into 3 groups according to their baseline NIH Stroke Scale (NIHSS) scores (0-4, 5-15, or ≥16).ResultsAt 24 h after randomization, mean systolic BP differences (95% CIs) were -8.5 (-10.0 to -7.1), -9.8 (-11.4 to -8.3), and -9.1 (-14.4 to -3.8) mm Hg between the treatment and control groups (all p values <0.001) for patients with a baseline NIHSS score of 0-4, 5-15, and ≥16, respectively. At day 7 after randomization, the corresponding mean systolic BP differences were -9.3 (-10.5 to -8.2), -9.1 (-10.3 to -7.8), and -10.1 (-15.1 to -5.1) mm Hg between the treatment and control groups (all p values <0.001). The primary outcome was not significantly different between the treatment and control groups at day 14 or hospital discharge among all NIHSS subgroups (p value for homogeneity = 0.66). ORs (95% CI) associated with treatment were 1.14 (0.87-1.49, p = 0.33), 1.04 (0.86-1.25, p = 0.70), and 0.67 (0.18-2.44, p = 0.54) for patients with a baseline NIHSS score of 0-4, 5-15, and ≥16, respectively. The composite outcome of death and major disability at 3-month follow-up did not differ between the 2 comparison groups for all NIHSS subgroups. In addition, vascular events and recurrent stroke were not significantly different between the 2 comparison groups at the 3-month follow-up visit among all NIHSS subgroups except that there was a suggestive risk reduction for recurrent stroke among those with an NIHSS score of 5-15 (OR 0.45, 95% CI 0.20-0.99, p = 0.05).ConclusionEarly BP reduction with antihypertensive medications did not reduce or increase the risk of death, major disabilities, recurrent instances of stroke, and vascular events in acute ischemic stroke patients with a variety of disease severities.
