To elucidate the role of inflammatory cytokines in Acute Ischemic Stroke patients
Acute ischemic stroke (AIS) is one of the leading causes of mortality and long-term disability. Ischemic changes results in inflammatory process characterized by various molecules and cytokines. There is limited data on the early changes and interaction in these cytokines. The aim of this study is to characterize the inflammatory response and explore the interaction of multiple cytokines and molecules among acute ischemic stroke (AIS) patients.
This is a prospective study of AIS patients presented to a tertiary care hospital within 24 hours from the symptom onset. Patients with prior history of stroke, autoimmune diseases, and neurodegenerative diseases were excluded. Plasma samples were collected on admission and at 24 hours. Cytokines and molecules were analyzed using enzyme-linked immunosorbent assay (ELISA). R-software was used for evaluating the differences among the molecules.
A total of 100 patients (males: 54; females: 46) from Caucasian, Hispanic, and Native American descent were included. Cytokine quantification observed a significant increase in PDGF, MPO, and MMP-9 among cases as compared to the controls at admission and 24 hours. Moreover, the levels of IL-33, IL-36, PDGF, MMP-9, and TNF-α decreases over time. Furthermore, IL-1 and IL-23 were negatively corelated with NIHSS, while the levels of IL-6 were positively corelated with infarct volume.
