Abstract Background Blood glucose levels that are too high or too low after traumatic brain injury (TBI) negatively affect patient prognosis. This study aimed to demonstrate the relationship between blood glucose levels and the Glasgow Outcome Score (GOS) in TBI patients. Methods This study was based on a randomized, dual-center, open-label clinical trial. A total of 208 patients who participated in the randomized controlled trial were followed up for 5 years. Information on the disease, laboratory examination, insulin therapy, and surgery for patients with TBI was collected as candidate variables according to clinical importance. Additionally, data on 5-year and 6-month GOS were collected as primary and secondary outcomes, respectively. For multivariate analysis, a generalized additive model (GAM) was used to investigate relationships between blood glucose levels and GOS. The results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). We further applied a two- piecewise linear regression model to examine the threshold effect of blood glucose level and GOS. Results A total of 182 patients were included in the final analysis. Multivariate GAM analysis revealed that a bell-shaped relationship existed between average blood glucose level and 5-year GOS score or 6-month GOS score. The inflection points of the average blood glucose level were 8.81 (95% CI: 7.43–9.48) mmol/L considering 5-year GOS as the outcome and were 8.88 (95% CI 7.43−9.74) mmol/L considering 6-month GOS score as the outcome. The same analysis revealed that there was also a bell relationship between average blood glucose levels and the favorable outcome group (GOS score ≥ 4) at 5 years or 6 months. Conclusion In a population of patients with traumatic brain injury, blood glucose levels were associated with the GOS. There was also a threshold effect between blood glucose levels and the GOS. A blood glucose level that is either too high or too low conveys a poor prognosis. Trial registration ClinicalTrials.gov NCT02161055. Registered on 11 June 2014.

Abstract Background: Too high or low blood glucose levels after traumatic brain injury (TBI) negatively affect the prognosis of patients with TBI. This study aimed to examine the relationship between different levels of blood glucose in insulin therapy and Glasgow Outcome Score (GOS) in patients with TBI.Methods: This study was based on a randomized, dual-center, open-label clinical trial. A total of 208 patients who participated in the randomized controlled trial were followed up for 5 years. The information on disease, lab examination, insulin therapy, and operation of patients with TBI was collected. Also, the data on 5-year and 6-month GOS were collected as primary and secondary outcomes. The univariate analysis was used to detect variables that might contribute to outcomes, while the multivariate regression analysis was used to reveal the independent relationship between insulin therapy and outcomes. A generalized additive model (GAM) was used to investigate dose–response relationships between blood glucose levels and GOS. The results were presented as odds ratios (ORs) with their 95% confidence intervals (95% CIs). We further applied a two-piecewise linear regression model to examine the threshold effect of blood glucose level and GOS.Results: A total of 182 patients were involved in the final analysis. Compared with the non-intensive insulin therapy group, the 5-year GOS in the moderate-control intensive insulin therapy (IIT) group and the slight-control IIT group was 1.45 and 1.39 higher, respectively (both P < 0.05); the 5-year GOS in the strict-control IIT group was 0.23 higher (P > 0.05). GAM revealed that a bell-shaped relationship existed between blood glucose levels in insulin therapy and 5-year or 6-month GOS. The inflection points of the mean blood glucose level were 6.73 and 8.97 mmol/L considering 5-year GOS as the outcome and were 6.95 and 8.88 mmol/L considering 6-month GOS as the outcome. The multivariate analysis showed that the 5-year GOS in the medium-level group (≥6.73 and <8.97 mmol/L) increased by 0.83 [95% confidence interval (CI): 0.22–1.47] compared with that in the low-level group (<6.73 mmol/L). Also, the 5-year GOS in the medium-level group increased by 0.57 (95% CI: 0.02–1.08) compared with that in the high-level group (≥8.97 mmol/L).Conclusion: A proper blood glucose range in insulin therapy could improve the outcomes of patients with TBI; the range was 6.73–8.97 mmol/L according to our limited analysis.Clinical Trial Registration: ClinicalTrials.gov, NCT02161055.

Poor Outcomes

Hyperglycemia, hypoglycemia, and variable blood glucose levels are associated with poor outcomes in critically ill patients. Patients with acute brain injury are sensitive to changes in glycemic levels because brain metabolism depends on a continuous, reliable supply of glucose. Numerous studies have shown that even moderate hypoglycemia may cause pronounced neuroglycopenia. Conversely hyperglycemia, which is prevalent in neurocritically ill patients, has been related to adverse outcomes after traumatic brain injury, ischemic stroke, intracranial hemorrhage, and subarachnoid hemorrhage.

Objective This study was performed to evaluate the effect of two different methods of controlling glycemic variability (GV) in patients with severe traumatic brain injury (STBI) undergoing surgery. Methods Patients with STBI were randomly grouped into a conventional adjustment process (CAP) group and modified Leuven’s adjustment process (mLAP) group. Each group included 50 patients. Blood glucose levels were continuously monitored and data were recorded and analyzed. Results The mean blood glucose level was stable in both groups for 5 days postoperatively with no significant difference. The standard deviation of the blood glucose level, mean amplitude of glycemic excursions, and glycemic lability index were significantly higher in the CAP than mLAP group for the first 2 days. In the final 3 days, no significant differences were observed between the two groups. The incidence of hypoglycemia was significantly higher in the CAP than mLAP group on the first day. This value gradually declined during the following 4 days, but the difference between the two groups was not significant. Conclusion The mLAP produced more favorable results than the CAP for GV control in the early stage after surgery for STBI.

This study was conducted to document temporal patterns of blood glucose level changes during the first 10-day critical period and to identify factors that influence stress-induced hyperglycemia development in brain injury patients. The medical records of 190 brain injury patients were retrospectively reviewed. Blood glucose levels in the poor recovery group were significantly higher than in the good recovery group, particularly during the first 72 hr (158-172 mg/dl). The poor recovery group showed persistent, fluctuating hyperglycemia, whereas the good recovery group exhibited hyperglycemic peaks during the first 3 days that subsequently reduced linearly to normal. Gender, preexisting hypertension, disease severity at admission, total calorie intake, and steroid use were found to influence stress-induced hyperglycemia development significantly. In conclusion, close monitoring and adjustment are required to maintain safe blood glucose levels and the development of protocols for safe glycemic management is essential to improve critical care in brain injury patients.
