摘要

Introduction

Traumatic brain injury (TBI) refers to an impact of the brain within the skull resulting in an altered mental state. The study aim is to determine the effect of a high dose of N-acetylcysteine (NAC) on biochemical and inflammatory markers of neuronal damage and clinical outcomes in patients with moderate to severe TBI.

Methods

A randomized open label-controlled trial was conducted on 40 patients with moderate to severe TBI patients presented to the emergency unit within < 24 h since the trauma occurred and randomized into NAC and control groups 20 patients each. Serum samples for evaluation of biomarkers: malondialdehyde (MDA), interleukin-6 (IL-6), neuron-specific enolase (NSE), and S100B were withdrawn at baseline and on day 7. The patients were followed for 7 days and evaluated clinically by the Glasgow Coma Scale (GCS).

Results

There was a significant decrease in NSE and MDA levels on day 7 from baseline in NAC group (p < 0.001 and p < 0.001). Also, S100B and IL-6 decreased significantly in NAC group on day 7 from baseline (p = 0.003 and p < 0.001 consequently) compared to control group. Moreover, patients in NAC group showed a significantly shorter length of stay at intensive care unit (ICU) (p = 0.038). There was a significant increase in GCS in NAC group on day 7 from baseline (p = 0.001).

Conclusion

Adjunctive early use of high-dose NAC significantly reduced inflammatory and oxidative markers and had neuroprotective effect which may be a novel treatment option for moderate to severe TBI patients.
