Abstract OBJECTIVE Traumatic brain injury (TBI) causes an increase in matrix metalloproteinases (MMPs), which are associated with neuroinflammation, blood-brain barrier disruption, hemorrhage, and cell death. We hypothesized that patients with TBI have an increase in MMPs in ventricular cerebrospinal fluid (CSF) and plasma. METHODS Patients with TBI and a ventricular catheter were entered into the study. Samples of CSF and plasma were collected at the time of catheter placement and at 24 and 72 hours after admission. Seven TBI patients were entered into the study, with 6 having complete data for analysis. Only patients who had a known time of insult that fell within a 6-hour window from initial insult to ventriculostomy were accepted into the study. Control CSF came from ventricular fluid in patients undergoing shunt placement for normal pressure hydrocephalus. Both MMP-2 and MMP-9 were measured with gelatin zymography and MMP-3 with Western immunoblot. RESULTS We found a significant elevation in the levels of the latent form of MMP-9 (92-kD) in the CSF obtained at the time of arrival (P < 0.05). Elevated levels of MMP-2 were detected in plasma at 72 hours, but not in the CSF. Using albumin from both CSF and blood, we calculated the MMP-9 index, which was significantly increased in the CSF, indicating endogenous MMP production. Western immunoblot showed elevated levels of MMP-3 in CSF at all times measured, whereas MMP-3 was not detected in the CSF of normal pressure hydrocephalus. CONCLUSION We show that MMPs are increased in the CSF of TBI patients. Although the number of patients was small, the results were robust and clearly demonstrated increases in MMP-3 and MMP-9 in ventricular CSF in TBI patients compared with controls. Although these preliminary results will need to be replicated, we propose that MMPs may be important in blood-brain barrier opening and hemorrhage secondary to brain injury in patients.

Background: Craniocerebral operation is the main method for the treatment of traumatic brain injury. However, it is very easy to be complicated with intracranial infection after operation, which affects the surgical efficacy and patient’s prognosis. It is also the main cause of surgical failure. It may also cause patient’s death for some patients with serious diseases. It is found that the infection after craniocerebral operation is often accompanied with abnormal changes of body-related treatment, in which the changes of serological indicators are more significant. Therefore, it is helpful to provide guidance for the prevention and judgment of patient’s postoperative infection by analyzing the patient’s serological indicators. Objective: To investigate the risk factors of intracranial infection and the levels of serum procalcitonin (PCT) and endothelin-1 (ET-1) in patients after traumatic brain injury. Methods: From January 2018 to January 2021, 58 patients with intracranial infection after traumatic brain injury (infection group) were selected, and 116 patients without intracranial infection after traumatic brain injury (non-infection group) were selected. The difference of clinical data between the two groups was analyzed. Serum PCT and ET-1 levels were measured in the two groups. Results: In the infection group, admission GCS scoring <8 points, operation time ≥4h, indwelling time of drainage tube ≥ 2d, preoperative ALB <35g/ L, mechanical ventilation and cerebrospinal fluid leakage were 63.79%, 72.41%, 43.10%, 68.97%, 32.76% and 68.97% respectively, which were obviously higher than those in the non-infection group (P<0.05). Logistic regression analysis results showed that admission GCS scoring, operation time, indwelling time of drainage tube, preoperative ALB, mechanical ventilation and cerebrospinal fluid leakage were the influencing factors of intracranial infection after traumatic brain injury (OR = 0.712,1.556,1.451,0.641,1.954 and 1.667, P<0.05); serum PCT and ET-1 in the infection group were (0.83 ± 0.20) mg/L and (0.87 ± 0.23) ng/L, respectively, which were significantly higher than those in the non-infection group (P<0.05); serum PCT and ET-1 in patients with different sex, age and pathogen had no significant difference (P>0.05); serum PCT and ET-1 area under ROC curve were 0.828 and 0.751, respectively P<0.05. Conclusion: The intracranial infection of patients with traumatic brain injury are affected by many factors including, admission GCS scoring, operation time, and so on, the levels of serum PCT and ET-1 in patients with intracranial infection are increased, which may be useful in predicting intracranial infection.

Abstract Matrix metalloproteinases (MMPs) are extracellular enzymes involved in the degradation of extracellular matrix (ECM) proteins. Increased expression of MMPs have been described in traumatic brain injury (TBI) and may contribute to additional tissue injury and blood–brain barrier damage. The objectives of this study were to determine longitudinal changes in cerebrospinal fluid (CSF) concentrations of MMPs after acute TBI and in relation to clinical outcomes, with patients with idiopathic normal pressure hydrocephalus (iNPH) serving as a contrast group. The study included 33 TBI patients with ventricular CSF serially sampled, and 38 iNPH patients in the contrast group. Magnetic bead-based immunoassays were utilized to measure the concentrations of eight MMPs in ventricular human CSF. CSF concentrations of MMP-1, MMP-3 and MMP-10 were increased in TBI patients (at baseline) compared with the iNPH group (p < 0.001), while MMP-2, MMP-9 and MMP-12 did not differ between the groups. MMP-1, MMP-3 and MMP-10 concentrations decreased with time after trauma (p = 0.001–0.04). Increased concentrations of MMP-2 and MMP-10 in CSF at baseline were associated with an unfavourable TBI outcome (p = 0.002–0.02). Observed variable pattern of changes in MMP concentrations indicates that specific MMPs serve different roles in the pathophysiology following TBI, and are in turn associated with clinical outcomes.
