Studija o serumu miR-185-5p u vezi sa procenom težine stanja i prognoze kod pacijenata sa traumatskim povredama mozga

Abstract

Background: This study aims to explore whether serum miR-185-5p levels are related to the injury severity and prognosis of traumatic brain injury patients. Methods: Serum miR-185-5p level was quantified in 120 TBI patients. The Glasgow Coma Scale (GCS) was used to grade the damage, and the Glasgow Outcome Scale (GOS) was used to evaluate the prognosis 3 months after TBI. Pearson correlation analysis was performed to determine the relationship between serum miR-185-5p level and injury severity and prognosis, and the value of serum miR-185-5p level to assess injury severity and prognosis was evaluated by receiver operating characteristic (ROC) curve. Results: Serum miR-185-5p level in moderate and severe TBI patients was higher than in mild TBI patients, and serum miR-185-5p was closely related to GCS score and GOS score. Serum miR-185-5p level higher than 0.36 could distinguish patients with mild to moderate TBI injury, with 72.97% sensitivity and 97.62% specificity, while that higher than 0.43 had 46.34% sensitivity and 91.89% specificity to distinguish moderate to severe TBI patients. Moreover, serum miR-185-5p levels higher than 0.36, with a sensitivity of 96.30% and a specificity of 60.24%, distinguished the poor prognosis of TBI patients. Serum miR185-5p level was an independent predictor of poor prognosis in TBI patients after 3 months and was effective in discriminating adverse outcomes at 3 months. Conclusions: Serum miR-185-5p level was significantly correlated with 3-month injury and adverse prognosis in TBI patients, suggesting that serum miR-185-5p level may be a biomarker that provides supplementary prognostic information and can be used to identify the risk of adverse prognosis in TBI patients.
