RESUMO

Purpose: Functional outcome prediction for patients with traumatic axonal injury (TAI) is not highly related to the MRI classifications. The aim of this study was to assess the accuracy in predicting functional outcome in patients with TAI with several MRI scoring methods and to define the most accurate method.Methods: Patients with TAI (2008-2014) confirmed on MRI <6 months after injury were included in this retrospective study. Long-term functional outcome was prospectively assessed using the Glasgow Outcome Score Extended. The Gentry classification is most used in clinical practice. This method was compared to methods that score lesion load, lesion locations, and to modified Gentry classifications. The area under the curve (AUC) was calculated for the scoring methods.Results: A total of 124 patients with TAI were included, medium follow-up 52 months. The AUC for the Gentry classification was 0.64. All tested methods were poor predictors for functional outcome, except for the 6-location score (area under the curve: 0.71). No method was significantly better than the Gentry classification.Conclusion: The Gentry classification for TAI correlates with functional outcome, but is a poor predictor for the long-term functional outcome. None of the other tested methods was significantly better.

RESUMO

PURPOSE: 1) To determine the clinical expression and consequences of autonomic dysregulation in patients with diffuse axonal injury (DAI), and 2) to study the use of the "paroxysmal sympathetic hyperactivity assessment measure" (PSH-AM). METHODS: Patients clinically diagnosed with autonomic dysregulation were selected from a cohort involving 116 patients with DAI. We studied the incidence of autonomic features, treatment, and outcome. In addition a systematic review was performed. RESULTS: Autonomic dysregulation was diagnosed in 19 of 116 (16.4%). Lower age (OR 0.95) and higher DAI grade (OR 7.2) were risk factors for autonomic dysregulation. Autonomic dysregulation was associated with an unfavourable outcome (OR 5.6) and a longer ICU and hospital stay. On the PSH-AM 57.9% (n = 11) scored a probable paroxysmal sympathetic hyperactivity (PSH), 36.8% (n = 7) scored possible, and 5.2% (n = 1) scored unlikely. The review yielded 30 articles. The incidence of autonomic dysregulation after TBI varied from 7.7-32.6% (mean 13.5%). TBI patients with autonomic dysregulation had a longer ICU stay and poorer outcome. CONCLUSION: Patients with DAI and autonomic dysregulation had a longer ICU stay and a poorer outcome compared to patients without autonomic dysregulation. The PSH-AM is a potential valuable tool to determine the likelihood of autonomic dysregulation.

RESUMO

Functional outcome and quality of life are difficult to predict in patients with diffuse axonal injury (DAI) after traumatic brain injury (TBI). The primary aim of this cross-sectional cohort study was to assess the long-term functional outcome in patients with DAI and to identify prognostic factors. Second, health-related quality of life (HRQL) at long-term follow-up was assessed. Patients ≥16 years of age with TBI and DAI (admitted 2008-2014) were included. Clinical and imaging data were collected. The primary outcome parameter was the Glasgow Outcome Scale Extended (GOSE) at long-term follow-up. Second, the HRQL was assessed with the Quality Of Life after Brain Injury (QOLIBRI) questionnaire. DAI was diagnosed in 185 patients. Long-term functional outcome was obtained in 134 patients (72%), median follow-up was 54 months (range 14-100); and 51% had a favorable outcome (GOSE 6-8). Independent prognostic factors were age, pupillary reaction, Hb, DAI grading, and return of consciousness ≤7 days. Sixty-two percent had a good HRQL, after a median follow-up of 57 months (range 14-100) with age as an independent prognostic factor. More than half of patients with DAI had a favorable functional outcome and a good HRQL at long-term follow-up. Also in patients with a DAI grade 3, a favorable outcome was seen. HRQL is a clinically relevant outcome measure because it reflects perceived outcome by patients. Independent prognostic variables for functional outcome were factors obtained in the acute phase after injury, whereas age was an independent prognostic factor for HRQL.

RESUMO

OBJECTIVE: To determine the prognosis of adult patients with traumatic brain injury (TBI) and diffuse axonal injury (DAI). METHODS: Online search (PubMed, Embase and Ovid Science Direct) of articles providing information about outcome in (1) patients with DAI in general, (2) DAI vs. non-DAI, (3) related to magnetic resonance imaging (MRI) classification and (4) related to lesion location/load. A reference check and quality assessment were performed. RESULTS: A total of 32 articles were included. TBI patients with DAI had a favourable outcome in 62%. The risk of unfavourable outcome in TBI with DAI was three times higher than in TBI without DAI. Odds ratio (OR) for unfavourable outcome was 2.9 per increase of DAI grade on MRI. Lesions located in the corpus callosum were associated with an unfavourable outcome. Other specific lesion locations and lesions count showed inconsistent results regarding outcome. Lesion volume was predictive for outcome only on apparent diffusion coefficient and fluid attenuation inversion recovery MRI sequences. CONCLUSIONS: Presence of DAI on MRI in patients with TBI results in a higher chance of unfavourable outcome. With MRI grading, OR for unfavourable outcome increases threefold with every grade. Lesions in the corpus callosum in particular are associated with an unfavourable outcome.
