Abstract P450: Serum Arachidonic Acid Levels in Relation With Outcome of Acute Intracerebral Hemorrhage

Introduction: The correlation between serum polyunsaturated fatty acids (PUFAs) such as Eicosapentaenoic Acid (EPA), Docosahexaenoic Acid (DHA), Arachidonic Acid (AA) and Dihomogammalinolenic Acid (DHLA) levels and clinical outcomes of cardiovascular disease are previously reported. The aim was to investigate serum PUFAs including AA levels to clinical outcome in intracerebral hemorrhage (ICH) patients. Method: From Nov 2012 to Nov 2019, ICH patients within 24 hours from the onset were enrolled. All patients underwent radiological investigations and laboratory examinations including measurement of serum PUFAs levels on admission. We divided patients into two groups, favorable outcome group (mRS at 3 months 0-3) and poor outcome group (mRS at 3 months 4-6). We compared baseline variables including serum PUFAs levels between two groups. Result: We enrolled 142patients (87 male, median age 60 years old, median NIHSS score 8). Of them, 113 patients (80%) were favorable outcome group and 29 patients (20%) were poor outcome group. Higher NIHSS score and larger size of hematoma on admission were found in poor outcome group (median NIHSS score 6 of favorable outcome vs. 14 of poor outcome, p Conclusion: Serum AA levels may play an important role in predicting the outcome in ICH.
