Methods: Data from brain CT, Glasgow Coma Scale (GCS) at admission, and 6-month Glasgow Outcome Scale (GOS) and mod ified Rankin Scale (mRS) were collected for 151 prospectively recruited patients with TBI. IL-1RN and IL-1B genotypes were determined using standard methods. Presence vs absence of any type of brain hemorrhage was the main outcome. Type o f brain hemorrhage, GCS at admission, and 6-month GOS and mRS were secondary ou tcomes. Odd ratios (ORs) and corresponding 95%CI were calculated using logistic regression analyses. In adjusted models, the associations were controlled for a ge, gender, diffuse brain edema, volume of intracranial hematoma, neurosurgical intervention, and GCS at admission. p values less than 0.01 were considered sign ificant. Results: Compared with noncarriers, IL-1RN allele 2 carriers had highe r odds of having cerebral hemorrhages after TBI (adjusted OR = 4.57; 95%CI = 1. 67 to 12.96; p = 0.004). The associations for (-511) IL-1B polymorphism were n ot significant. Conclusion: There is an association between the presence of inte rleukin-1RN allele 2 and posttraumatic brain hemorrhage.展开更多
