Abstract

AMAYA-CHANAGA, Carlos I; NARANJO, Néstor Fernando; CASTELLANOS, Jorge A  and  SILVA, Federico Arturo. Inflammatory response in a first ischemic stroke: differences by gender. Acta Neurol Colomb. [online]. 2014, vol.30, n.1, pp.6-15. ISSN 0120-8748.

Introduction. Controversy persists regarding gender differences in the incidence, severity and mortality associated with ischemic stroke. Objective. To describe the inflematory response in patients with a first ischemic stroke behavior in women and men over 45 year-old. Materials and Methods. 50 postmenopausal women and 50 men, over 45 years old with a first-ever ischemic stroke were included. Differences in symptoms, medical history, severity, inflammatory response and mortality were evaluated and analyzed among both genders. Results: Postmenopausal women were older at the first-ever ischemic stroke (72,9 + 9,8 years vs. 69,7 + 9,03 years, p=0,09), with no differences in stroke severity (NIHSS median score 10,4 + 7,61 in women vs. 10,46 + 4,96 in men), with higher levels of total cholesterol (216,39 + 50,61 vs. 188,76 + 49,56; p=0,007), LDL cholesterol (140,40 + 39,57 vs. 121,3 + 45,36; p=0,032), HDL cholesterol (44,69 + 15,52 vs. 37,67 + 12,23; p= 0,013), triglycerides (158,03 + 74,65 vs. 144,05 + 55,64; p=0,291) and blood glucose (142,77 + 71,60 vs. 138,16 + 115,75; p=0,826); less inflammatory response assessed by CRP, IL-6 and TNF-α, and hospital mortality than men (6,52% vs. 14%, p=0,231). Conclusion. Gender differences in ischemic stroke behavior observed in this study could be explained by the cardiovascular protection of premenopausal hormonal factors or inherent factors in women that confers a protection state against ischemic stroke.
