Assessing the blood concentration of new adipocytokines in patients with ischaemic stroke.

INTRODUCTION: Ischaemic stroke (IS) is a disease that is a common cause of death and one of the most common causes of disability in adults. There is a continuous need to conduct stroke pathogenesis studies. A certain role here can be attributed to adipose-derived hormones. The aim of this paper is to assess the blood concentration for selected adipocytokines: omentin-1, irisin, protein-1 related with C1q/TNF (CTRP1), vaspin and nesfatin-1 in IS patients, and an attempt to define their role as risk factors for ischaemic stroke. MATERIAL AND METHODS: The study included 46 patients with ischaemic stroke (27 females, 19 males, average 67.6 years of age). The control group consisted of 32 patients (16 females, 16 males, average 64.1 years of age) who had never had cerebrovascular diseases. RESULTS: The concentration of omentin-1 and CTRP1 in the group of stroke patients was higher than in the control group, whereas the concentrations of nesfatin-1 and irisin was significantly lower than in the control group. The vaspin level was similar in both groups of patients. Statistical analysis using logistic regression allows us to find that CTRP1 can be a significant stroke risk factor. A statistically significant positive correlation was found between the concentration of CTRP1 and NIHSS. However, no correlation between the concentration of other adipocytokines under investigation and the severity of ischaemic stroke was found. CONCLUSIONS: From among the adipocytokines under investigation, higher concentrations of omentin-1 and CTRP1 and lower blood concentrations of nesfatin-1, irisin significantly increase the odds of getting to the group of ischaemic patients. It seems that CTRP1 can be an independent predictive factor of IS.

Selected adipose tissue hormones in the blood of patients with ischaemic cerebral stroke.

INTRODUCTION: Despite considerable progress in knowledge, ischaemic stroke is still a disease that causes serious clinical problems. A role in its pathogenesis can be attributed to i.a. adipose tissue hormones. The aim of this paper is to assess the blood levels of selected adipocytokines in patients during the acute phase of ischaemic stroke as compared to healthy persons, and an attempt to indicate a correlation between their blood concentrations and the level of stroke severity and its outcomes. MATERIAL AND METHODS: The study included 46 patients with fresh ischaemic stroke (27 females, 19 males, average age 67.6 years). All patients had a CT scan of the head, their neurological condition was assessed using a stroke severity scale, and their blood levels of resistin, chemerin, and visfatin were tested. The control group consisted of 32 patients (16 females, 16 males, average age 64.1 years) who had never suffered cerebrovascular diseases. RESULTS: Elevated levels of both resistin and chemerin were found in the group of patients with ischaemic stroke (9.17 ± 2.95 ng/mL vs. 6.55 ± 2.01 ng/mL for resistin and 265.0 ± 59.3 ng/mL vs. 191.0 ± 43.6 ng/mL for chemerin). It was also found that the blood concentration of chemerin was higher in females than in males with stroke. However, no difference was found in visfatin blood concentration between the group with ischaemic stroke and the control group (1.65 ± 1.09 ng/mL vs. 1.5 ± 1.39 ng/mL). CONCLUSIONS: Higher resistin and chemerin blood concentrations significantly increase the risk of ischaemic stroke. The level of stroke severity at the moment of its occurrence and during its course do not depend on the concentrations of adipocytokines under analysis.
