Serum Hepatocyte Growth Factor Is Probably Associated With 3-Month Prognosis of Acute Ischemic Stroke.

ABSTRACT: BACKGROUND AND PURPOSE:Serum hepatocyte growth factor (HGF) is positively associated with poor prognosis of heart failure and myocardial infarction, and it can also predict the risk of ischemic stroke in population. The goal of this study was to investigate the association between serum HGF and prognosis of ischemic stroke. METHODS:A total of 3027 acute ischemic stroke patients were included in this post hoc analysis of the CATIS (China Antihypertensive Trial in Acute Ischemic Stroke). The primary outcome was composite outcome of death or major disability (modified Rankin Scale score ?3) within 3 months. RESULTS:After multivariate adjustment, elevated HGF levels were associated with an increased risk of primary outcome (odds ratio, 1.50; 95% confidence interval, 1.10-2.03; Ptrend=0.015) when 2 extreme quartiles were compared. Each SD increase of log-transformed HGF was associated with 14% (95% confidence interval, 2%-27%) increased risk of primary outcome. Adding HGF quartiles to a model containing conventional risk factors improved the predictive power for primary outcome (net reclassification improvement: 17.50%, P<0.001; integrated discrimination index: 0.23%, P=0.022). The association between serum HGF and primary outcome could be modified by heparin pre-treatment (Pinteraction=0.001), and a positive linear dose-response relationship between HGF and primary outcome was observed in patients without heparin pre-treatment (Plinearity<0.001) but not in those with heparin pre-treatment. CONCLUSIONS:Serum HGF levels were higher in the more severe stroke at baseline, and elevated HGF levels were probably associated with 3-month poor prognosis independently of stroke severity among ischemic stroke patients, especially in those without heparin pre-treatment. Further studies from other samples of ischemic stroke patients are needed to validate our findings.

Project description:BACKGROUND:Although adiponectin is a major adipocytokine that affects the pathogenesis of various cardiovascular diseases, its clinical significance in stroke remains controversial. The purpose of this study was to assess the impact of serum adiponectin levels on functional prognosis in patients with ischemic stroke. METHODS:This was a prospective, observational cohort study. Consecutive first-ever ischemic stroke patients without any pre-morbid handicap admitted to our hospital were identified from December 2017 to December 2018. Serum concentration of adiponectin was routinely measured within the first 24 h after admission by a commercially available sandwich ELISA. Associations between adiponectin and either clinical severity at admission, poor outcomes or mortality at 3-month after admission were analyzed using logistic regression to obtain odds ratios (OR) and 95% confidence intervals (CI). RESULTS:The serum level of adiponectin was obtained in 227 patients with a median value of 7.0 ?g/ml, which was significantly higher (P?<?0.001) than in those heathy control. Adiponectin levels were associated with moderate-to-high stroke, and risk increased by 12% (OR?=?1.12; 95% CI 1.03-1.25; P?=?0.002). Patients with a poor outcome and nonsurvivors had significantly increased adiponectin levels on admission (P?<?0.001, all). In multivariate logistic regression analysis, adiponectin was an independent predictor of functional outcome and mortality, and risk increased by 24% (OR?=?1.24, 95% CI 1.13-1.37; P?<?0.001) and 31% (1.31 [1.18-1.46], P?<?0.001), respectively. Kaplan-Meier analysis suggested that the patients with high serum adiponectin levels had a higher risk of death than those patients with low levels (log-rank test P?<?0.001). CONCLUSIONS:Our results show that high adiponectin is associated with stroke severity and support the hypothesis that adiponectin can be serve as a biomarker of poor outcome after stroke, independent of baseline variables.

Project description:BackgroundBile acids (BAs) not only play an important role in lipid metabolism and atherosclerosis but also have antiapoptotic and neuroprotective effects. However, few studies have focused on the relationship of the total bile acid (TBA) levels with the severity and prognosis of acute ischemic stroke (AIS).ObjectivesThe aim of this study was to investigate the potential associations of the fasting serum TBA levels on admission with the stroke severity, in-hospital complication incidence and 3 -month all-cause mortality in patients with AIS.MethodsA total of 777 consecutive AIS patients were enrolled in this study and were divided into four groups according to the quartiles of the serum TBA levels on admission. Univariate and multivariate logistic regression analyses were used to explore the relationship between the fasting TBA levels and the stroke severity, in-hospital complications, and 3-month mortality in AIS patients.ResultsPatients in group Q3 had the lowest risk of severe AIS (NIHSS > 10) regardless of the adjustments for confounders (P < 0.05). During hospitalization, 115 patients (14.8%) had stroke progression (NIHSS score increased by ≥ 2), and 222 patients (28.6%) developed at least one complication, with no significant difference among the four groups (P > 0.05). There was no significant difference in the incidence of pneumonia, urinary tract infection (UTI), hemorrhagic transformation (HT), gastrointestinal bleeding (GIB), seizures or renal insufficiency (RI) among the four groups (P > 0.05). A total of 114 patients (14.7%) died from various causes (including in-hospital deaths) at the 3-month follow-up, including 42 (21.3%), 26 (13.3%), 19 (9.9%) and 27 (13.9%) patients in groups Q1, Q2, Q3 and Q4 respectively, with significant differences (P = 0.013). After adjusting for confounding factors, the risk of death decreased (P -trend < 0.05) in groups Q2, Q3, and Q4 when compared with group Q1, and the OR values were 0.36 (0.16-0.80), 0.30 (0.13-0.70), and 0.29 (0.13-0.65), respectively.ConclusionsTBA levels were inversely associated with the 3-month mortality of AIS patients but were not significantly associated with the severity of stroke or the incidence of complications.
