How to Design Economic Predictive Laboratory Panel Evaluating Acute Ischemic Stroke Outcome

Background: acute ischemic stroke (AIS) remains the third cause of death and disability, and acute phase responses, both increasing international normalized ratio (INR) and activated partial thromboplastin time (APTT) are associated with worse outcome. Erythrocyte sedimentation rate (ESR) serves as severity marker, and non-fasting triglycerides (TG) indicates remnants of chylomicrons and very low density lipoproteins potentially pro-inflammatory. Aims: to design predictive economic panel evaluating AIS. Patients and methods: 100(AIS) patients were included, clinically evaluated by Scandinavian Stroke Scale (SSS) and Modified Rankin Score (MRS), subjected to complete blood count (CBC) on Cell-Dyne3700, manual ESR, INR and APTT on SYSMEX-CA1500, serum uric acid (SUA), serum albumin and non-fasting (TG) on Beckman Coulter AU480. Statistical analysis: STATA intercooled version 9.2. Results: odd ratio (OR), confidence interval (CI) of (MRS) in correlation to WBCs count in quartile (Q)3, 4 (OR 8.14, CI 2.29 - 8.90, significant P = 0.01; and OD13.5, CI 3.39 - 53.68, high significant P = 0.001 respectively), to APTT in Q3 (OD 4.15, CI 1.09 - 15.82, P = 0.04), SUA in Q3 (OD 0.19, CI 0.05 - 0.68, P = 0.01), TG in Q3,4 (OD 0.24 CI 0.06 - 0.88, P = 0.03; and OD 0.09, CI 0.02 - 0.34 P = 0.001 respectively) and serum albumin in Q3(OD 0.13, CI 0.04 - 0.51, P = 0.003), insignificant correlations to ESR, INR and platelets. Conclusion: according to (MRS), the economic predictive panel should be included WBCs, APTT, SUA, and non-fasting TG with serum albumin as prognostic tool evaluating functional disability in AIS.
