OBJECTIVE: To test the hypothesis that pre-treatment Creactive protein (CRP) predicts outcome in stroke patients undergoing intravenous thrombolysis (IVT) treatment. METHODS: We analyzed the data of 111 consecutive patients with IVT within 6 hours of stroke onset for stroke involving the middle cerebral artery territory and admission CRP < or = 6 mg/dl. RESULTS: CRP levels were consistently, yet non-significantly lower in patients with unfavourable outcome definitions. Median (range) CRP levels were 0.3 (0-5.9) mg/dl vs. 0.4 (0-5.7) mg/dl (p = 0.13) in patients dependent or dead after 3 months (modified Rankin Scale score > 2; n = 59) vs. independent patients (n = 52); 0.2 (0.1-1.5) mg/dl vs. 0.4 (0-5.9) mg/dl (p = 0.28) in patients dead after 3 months (n = 14) versus survivors (n = 97); and 0.2 (0.1-0.7) mg/dl vs. 0.4 (0-5.9) mg/dl (p = 0.09) in patients with significant neurological deterioration within 24 hours (increase in > or = 4 points on National Institute of Health Stroke scale; n = 9) vs. patients without early deterioration (n = 102). Independent predictors of dependency/death after 3 months, identified by multivariate logistic regression analyses, were baseline NIHSS score (OR = 1.31, 95 % CI 1.16-1.48, p < 0.001), time from onset to treatment (OR = 1.01, 95 % CI 1.0-1.02, p = 0.024), and presence of diabetes (OR = 8.16, 95 % CI 1.18-56.5, p = 0.033). CONCLUSION: Pre-treatment CRP clearly failed to predict outcome in stroke patients treated with IVT. Our findings contradict previously published work and highlight the need for further research on this topic.
