ABSTRACT

OBJECTIVES: Apathy is a frequent neuropsychiatric syndrome after stroke. We determined whether pre-morbid and early post-stroke apathy predicts dementia 3 months after stroke. METHODS: We included ischemic stroke patients without dementia who participated in the Prospective Observational Polish Study on post-stroke delirium. We used the Neuropsychiatric Inventory and clinician-reported version of Apathy Evaluation Scale to score apathy symptoms before stroke and on day 8 after stroke. Patients underwent neuropsychological examination 3 months after stroke. RESULTS: Of 422 patients with ischemic stroke and without pre-stroke dementia, 194 patients (mean age: 67.5 ± 12.3; 45.9% female) underwent neuropsychological examination. Dementia was diagnosed in 21.6% of them. Patients with dementia had higher apathy scores before stroke (mean: 0.9 ± 1.7 vs. 0.2 ± 0.9, p < 0.01) and on day 8 (mean: 37.2 ± 9.3 vs. 29.0 ± 9.6, p < 0.01). Depressive symptoms did not differ between groups. In multivariate analysis adjusted for age, diabetes mellitus, stroke severity and in-hospital delirium, apathy symptoms before stroke and on day 8 after stroke predicted post-stroke dementia (adjusted OR: 1.59, 95%CI: 1.13-2.26, p = 0.01 and OR: 1.06, 95%CI: 1.01-1.11, p = 0.03, respectively). CONCLUSIONS: Pre-stroke and early post-stroke apathy independently from age, stroke severity and delirium predicted dementia 3 months after stroke. Apathy might be useful in identifying at-risk patients.

ABSTRACT

BACKGROUND: Post-stroke depressive symptoms (DS) can be chronic or transient, occurring shortly or long after stroke and lasting only few months. It remains unclear if the prognosis differs between patients with DS in the acute phase of stroke and those who develop DS several months later. We aimed to determine whether outcomes vary among patients with different trajectories of post-stroke depressive symptoms. METHODS: Of 698 enrolled patients with ischemic stroke, we included 335 participants (median age: 68, 48% female) who were assessed for DS both 8 days and 3 months post-stroke. We divided patients into 4 groups: without greater DS (Group 1), only earlier DS (Group 2), only later DS (Group 3), and persistent DS (Group 4). Logistic regression was used to determine the association between DS and 3- and 12-month functional outcome. RESULTS: Group 2 was predominantly female and had the highest rate of previous stroke or transient ischemic attack. Group 3 was more likely to suffer from delirium and more severe stroke. Group 4 had the highest frequency of vascular risk factors, pre-morbid psychiatric symptoms, and cognitive decline. In multivariate analysis, Group 3, but not Groups 2 and 4, had an increased risk of poor 3- and 12-month functional outcome (adjusted OR 2.59, 95% CI 1.64-4.07, P < 0.01 and OR 3.97, 95% CI 2.32-6.76, P < 0.01, respectively) compared with Group 1. CONCLUSIONS: Different trajectories of post-stroke DS are related to different outcomes. Patients who only have later DS also have the worst prognosis.

ABSTRACT

To determine the utility of lipopolysaccharide binding protein (LBP) and soluble CD14 (sCD14) as risk markers of stroke-associated pneumonia (SAP). We included 331 stroke patients. The plasma levels of LBP (median: 19.4 vs 15.3 µg/mL, P < 0.01) and sCD14 (median: 1.5 vs 1.4 µg/mL, P = 0.04) were elevated in SAP. In multivariate analysis, a higher level of LBP (OR: 1.09, 95%CI: 1.05-1.13), but not sCD14 (OR: 2.16, 0.94-4.97), was associated with SAP. The addition of LBP or sCD14 to the clinical model did not improve its discriminatory ability. Our results suggest the modest value of studied biomarkers for SAP prediction.

ABSTRACT

BACKGROUND AND PURPOSE: Depression and apathy are frequent neuropsychiatric disturbances after stroke and may appear together. Despite the overlap in symptoms between poststroke depression and apathy, these two syndromes might be associated with different prognoses and benefit from different treatments. We aimed to disentangle the relationship between early depressive and apathetic symptoms and outcome after stroke. METHODS: Of 698 enrolled patients with ischemic stroke, we included 443 participants (median age = 69 years, 51% female) who underwent depressive and apathetic symptom assessment on Day 8 after stroke. We divided patients into four groups: without greater depressive and apathetic symptoms (Group 1), with only apathetic symptoms (Group 2), with only depressive symptoms (Group 3), and with both depressive and apathetic symptoms (Group 4). RESULTS: After adjusting for age and stroke severity, Group 2 and Group 4 had an increased risk of poor 3-month outcome (odds ratio [OR] = 1.98, 95% confidence interval [CI] = 1.16-3.38, p = 0.01 and OR = 1.58, 95% CI = 1.24-2.01, p < 0.01, respectively). Group 2 and Group 4 also had an increased risk of poor 12-month outcome (OR = 3.85, 95% CI = 2.19-6.78, p < 0.01 and OR = 1.54, 95% CI = 1.22-1.96, p < 0.01, respectively) and mortality (hazard ratio [HR] = 2.76, 95% CI = 1.19-6.41, p = 0.02 and HR = 1.77, 95% CI = 1.32-2.38, p < 0.01, respectively). Compared with Group 1, Group 3 did not have an increased risk of unfavorable outcomes. CONCLUSIONS: Early apathetic, but not depressive, symptoms are related to worse outcomes after stroke. Our study underscores the importance of recognizing apathetic symptoms independently from depressive symptoms.

ABSTRACT

Systemic inflammation is associated with poor outcome after stroke. Glucocorticoids (GCs) play a fundamental role in limiting inflammation. The aim of this study was to explore the associations between GC sensitivity, systemic inflammation, and outcome after ischemic stroke. The study population compised 246 ischemic stroke patients (median age: 69.0 years; 41.1% female). To assess GC sensitivity, we incubated venous blood samples that were obtained at day 3 after stroke with lipopolysaccharide (10 ng/mL) and dexamethasone (10-6 mol/L). We defined the GC sensitivity index as the ratio of tumor necrosis factor α (TNFα) released after blood stimulation with lipopolysaccharide and dexamethasone to the amount of TNFα released after blood stimulation with lipopolysaccharide alone. A higher index indicates higher GC resistance. The patients with poor functional outcome had a higher GC sensitivity index than those with good outcome (median: 16.1% vs. 13.5%, P < 0.01). In a logistic regression analysis adjusted for age, stroke severity, pneumonia, leukocyte count, plasma interleukin-6, and TNFα release ex vivo, a higher GC sensitivity index was associated with a higher risk of poor outcome after stroke (OR 2.32, 95% CI 1.21-4.45, P = 0.01). In conclusion, GC resistance is associated with poor functional outcome after stroke.
