Background
The elevation of plasma D‐dimer levels may predict a higher risk of thrombosis and play a role in the pathological process of patients after spontaneous intracerebral hemorrhage (ICH). However, its function in predicting the prognosis of ICH has not been verified on large cases.
Patients and Methods
Retrospective cohort study of 1,332 consecutive patients with spontaneous ICH at an academic medical center was conducted. Functional outcome at three months after ICH was dichotomized using the modified Rankin Scale (0–2 versus 3–6). D‐dimer level in blood was analyzed within 1 hr of admission. An ICH outcome score combining D‐dimer level for evaluating poor functional outcome and mortality was tested.
Results
The proportion of patients with poor functional outcome and mortality at three months was significantly higher in patients with elevated D‐dimer level (
p
< .001). Multivariable analysis demonstrated that elevated D‐dimer level was an independent predictor of poor functional outcome (odds ratio 1.486, 95% confidence interval 1.086–2.060,
p
= .014) and mortality (odds ratio 2.015, 95% confidence interval 1.186–3.423,
p
= .01). An increasing ICH outcome score combining D‐dimer level was associated with increased poor functional outcome and mortality.
Conclusions
Elevated plasma D‐dimer level after spontaneous ICH is associated with poor functional outcome and mortality. The study suggests that elevated D‐dimer level has a predictive value for outcome and mortality in patients with spontaneous ICH.
IntroductionExosomal microRNAs (miRNAs) play an essential role in near and distant intercellular communication and are potential diagnostic and prognostic biomarkers for various cancers. This study focused on evaluation of exosomal miR-2276-5p in plasma as a diagnostic and prognostic biomarker for glioma.MethodsPlasma exosomes from 124 patients with glioma and 36 non-tumor controls were collected and subjected to quantitative real-time polymerase chain reaction (qRT-PCR) analysis for the exosomal miR-2276-5p expression. Bioinformatic analyses were performed to identify a gene target, and CGGA and TCGA databases were checked for evaluation of prognostic relevance.ResultsThe exosomal miR-2276-5p in glioma patients had a significantly decreased expression, compared with non-glioma patients (p < 0.01). Receiver operating characteristics (ROC) curve analyses were observed to regulate the diagnostic sensitivity and specificity of miR-2276-5p in glioma; the area under the curve (AUC) for miR-2276-5p was 0.8107. The lower expression of exosomal miR-2276-5p in patients with glioma correlated with poorer survival rates. RAB13 was identified as the target of miR-2276-5p which was high in glioma patients, especially those with higher tumor grades and correlated with poor survival.ConclusionThe circulating exosomal miR-2276-5p is significantly reduced in the plasma of glioma patients, and thus, it could be a potential biomarker for patients with glioma for diagnostic and/or prognostic purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
