Identifying reliable biomarkers to predict clinical outcomes can aid in improving patientmanagement and tailoring therapeutic interventions. This study aims to evaluate the prognostic value of C-reactive protein (CRP) levels inpredicting clinical outcomes, including functional recovery, incidence of vasospasm, and mortality, in SAH patients within the first 14 dayspost-hemorrhage Material and Methods: A retrospective analysis of 263 patients diagnosed with spontaneous SAH between 2018 and 2024 was conducted.Patients were classified into aneurysmal SAH (ASAH) and non-aneurysmal SAH (NASAH) groups based on digital subtraction angiographyfindings. CRP levels were measured daily for 14 days, and clinical outcomes were assessed using the Modified Rankin Scale and Kaplan-Meier survival analysis.Results: Patients with ASAH exhibited significantly higher CRP levels (median: 516 mg/L) and longer durations of CRP >100 mg/L comparedto NASAH patients. Higher CRP levels correlated positively with worse mRS scores and increased vasospasm incidence. Survival analysisrevealed that ASAH patients with CRP >200 mg/L had significantly reduced survival rates (45%) compared to those with lower CRP levels(72%, p < 0.001).Conclusion: Elevated CRP levels are strongly associated with poor functional outcomes, increased vasospasm, and higher mortalityin SAH patients, particularly in those with aneurysmal rupture.

Klinik sonuçları öngörebilecek güvenilir biyobelirteçlerin tanımlanması, hasta yönetimini iyileştirmeye ve tedavi yaklaşımlarınıbireyselleştirmeye katkı sağlayabilir. Bu çalışmanın amacı, SAK hastalarında ilk 14 gün içinde C-reaktif protein (CRP) düzeylerinin fonksiyoneliyileşme, vazospazm insidansı ve mortalite gibi klinik sonuçları öngörmedeki prognostik değerini değerlendirmektir.Gereç ve Yöntemler: 2018 ile 2024 yılları arasında spontan SAK tanısı almış 263 hastanın retrospektif analizi yapıldı. Dijital subtraksiyonanjiyografi bulgularına göre hastalar anevrizmal SAK (ASAK) ve anevrizma dışı SAK (ADSAK) olarak sınıflandırıldı. CRP düzeyleri 14 günboyunca günlük olarak ölçüldü ve klinik sonuçlar Modifiye Rankin Skalası ve Kaplan-Meier sağkalım analizi ile değerlendirildi.Bulgular: ASAK hastalarında CRP düzeyleri anlamlı olarak daha yüksekti (medyan: 516 mg/L) ve CRP >100 mg/L süresi ADSAK hastalarınagöre daha uzundu. Yüksek CRP düzeyleri, daha kötü mRS skorları ve artmış vazospazm insidansı ile pozitif korelasyon gösterdi. Sağkalımanalizinde, CRP >200 mg/L olan ASAK hastalarının sağkalım oranı (%45), daha düşük CRP düzeyine sahip olanlara kıyasla (%72) anlamlıolarak daha düşüktü (p < 0.001).Sonuç: Yüksek CRP düzeyleri, özellikle anevrizma rüptürü olan hastalarda, kötü fonksiyonel sonuçlar, artmış vazospazm ve yüksek mortaliteile güçlü bir şekilde ilişkilidir. CRP izleminin rutin klinik pratiğe dahil edilmesi, prognoz tahminini güçlendirebilir ve hedefe yönelik tedavilereyön verebilir. CR - 1. Peng L, Li X, Li H, Zhong Y, Lian J, Gao H, et al.
