Abstract:
Objective To investigate the relationship between serum trimethylamine oxide(TMAO),neurofilament light chain protein(NfL),peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α)expression levels and short-term prognosis in aneurysmal subarachnoid hemorrhage(aSAH)patients.Method A total of 125 aSAH patients(aSAH group)and 125 healthy volunteers in the same period(control group)who were admitted in heji hospital affiliated to Changzhi Medical College from March 2020 to June 2023 were selected.The serum expression levels of TMAO,NfL and PGC-1α were compared between control group and aSAH group.The aSAH patients were followed up for 6 months after discharge.Their prognosis were evaluated using Glasgow Outcome Scale(GOS)and they were further divided into good prognosis and poor prognosis groups according to the GOS results.The serum expression levels of TMAO,NfL and PGC-1α were compared between the two groups.The poor prognosis influencing factors were analyzed by multivariate Logistic regression analysis,the serum TMAO,NfL and PGC-1α value in predicting poor prognosis were analyzed by receiver operating characteristic(ROC)curve.Result The expression levels of serum TMAO and PGC-1 α in the aSAH group were(2.63±0.36)μmol/L and(0.51±0.13)ng/mL,respectively,which were lower than those in the control group(3.18±0.57)μmol/L and(0.81±0.16)ng/mL(P<0.05).The expression level of serum NfL was significantly higher in the aSAH group(64.48±14.35 pg/mL)than in the control group(28.36±8.82 pg/mL)(P<0.05).Compared with the good prognosis group whose serum levels of TMAO and PGC-1 α were(2.80±0.80)μmol/L and(0.58±0.16)ng/mL,respectively,the poor prognosis group had significantly lower serum TMAO[(2.29±0.63)μmol/L]and PGC-1 α[(0.36±0.12)ng/mL](P<0.05).In contrast,poor prognosis group had a significantly higher level of NfL(76.70±15.61)pg/mL compared to good prognosis group(58.52±10.52)pg/mL(P<0.05).The proportion of patients with hypertension,patients with diabetes,patients with large or giant aneurysms,patients with Hunt Hess grade Ⅲ-Ⅳ,patients with onset to hospital time>12 h,and the level of C-reactive protein(CRP)were higher in the poor prognosis group than in the good prognosis group(P<0.05).Hunt Hess grade Ⅲ-Ⅳ,elevated serum CRP and NfL were independent risk factors for poor prognosis in aSAH patients(P<0.05),while elevated TMAO and PGC-1 α were protective factors(P<0.05).The area under the curve(AUC)of serum TMAO,NfL,PGC-1 α,and their combined prediction of poor prognosis in aSAH patients were 0.726,0.830,0.862,and 0.956,respectively.The AUC of the combined detection was greater than that of each indicator detected separately.Conclusion Serum TMAO and PGC-1α are lowly expressed in aSAH patients,and serum NfL is highly expressed,which are related to the occurrence of short-term poor prognosis,the combined detection of the three indicators has a high predictive value for short-term poor prognosis in aSAH patients.
