Abstract:
Objective This study investigates the relationship of serum irfflammatory cytokine levels with intracranial pressure (ICP) in patients with severe traumatic brain injury (TBI) after surgery.Methods A total of 32 cases with severe TBI and placement of ICP monitor were prospectively enrolled.Serum was collected before surgery and every 12 h after surgery.Cytokines levels of interleukin (IL)-1β,IL-8,and tumor necrosis factor (TNF)-α were analyzed and compared with outcome of patients.Hourly values of ICP were recorded.The degree of ICP above treatment threshold (20 mm Hg) were calculated every 12 h as pressure times time dose(PTD-ICP20),which was compared with serum cytokine levels before (Pre) and after (Post) the 12-hour time period using linear regression method.Results Serum IL-1β (P＜0.05),IL-8 (P＜0.01) and TNF-a (P＜0.01) levels elevated dramatically after severe TBI and were significantly associated with outcome of patients.Mean PTD-ICP20 was (42.9 ± 60.2)mm Hg/h and was correlated with increased Pre-IL-8 (r=0.554,P＜0.001),Pre-TNF-α (r=0.597,P＜0.001),Post-IL-8 (r=0.629,P＜0.001) and Post-TNF-α (r=0.538,P＜0.001) levels.Conclusion Serum IL-8 and TNF-α demonstrated the most promising candidate bio.rnarkers of impending ICP elevation in this study.These findings indicate a feasible way of monitoring patients with severe TBI.
