Combination of Albumin/Fibrinogen Ratio and Admission Hunt-Hess Scale Score as an Independent Predictor of Clinical Outcome in Aneurysmal Subarachnoid Hemorrhage

BACKGROUND

The albumin/fibrinogen ratio (AFR) is an independent predictor of clinical outcomes of some diseases; however, the prognostic value of AFR and the admission Hunt-Hess (HH) score is still unclear for patients with an aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to assess the relationship between the AFR-HH score and 6-month outcomes of aSAH patients.

METHODS

The clinical characteristics of aSAH patients admitted to our department between December 2017 and December 2021 were retrospectively analyzed. The candidate risk factors were screened using univariate regression analysis, and the independence of the resultant risk factors was evaluated by binary logistic regression analysis. The predictive value of the combined AFR and HH score for unfavorable outcomes was assessed using receiver operating characteristic curve analysis.

RESULTS

A total of 112 aSAH patients were included. Binary logistic regression analysis showed the perioperative period AFR, Glasgow coma scale score, and admission HH score were independent risk factors for unfavorable outcomes for aSAH patients. The receiver operating characteristic curve analysis showed the predictive capacity of AFR plus the admission HH score outperformed the AFR, Glasgow coma scale score, and admission HH scale alone and the combination of the AFR and Glasgow coma scale score.

CONCLUSIONS

A low AFR during the perioperative period is associated with unfavorable outcomes for aSAH patients at 6 months. The combination of the AFR and admission HH scale score provides superior predictive capacity to either the AFR or HH scale score alone.

Prognostic Significance of the Preoperative Albumin/Fibrinogen Ratio in Patients with Esophageal Squamous Cell Carcinoma after Surgical Resection

Purpose: The purpose of the present study was to investigate the prognostic value of inflammatory and nutritional-based scores, including the albumin/fibrinogen ratio (AFR) and albumin/globulin ratio (AGR), in patients with esophageal squamous cell carcinoma (ESCC).

Methods: The medical records of 641 patients with resectable ESCC from our institution were retrospectively analyzed. The preoperative AFR and AGR were investigated based on serum albumin, globulin and plasma fibrinogen levels. X-tile software, Kaplan-Meier survival curves and Cox proportional hazard models were performed to identify their prognostic value. The predictive accuracy was evaluated by the concordance index (C-index), calibration plots, and decision curve analysis (DCA).

Results: The optimal cutoff values were 15.3 and 1.8 for AFR and AGR, respectively. Univariate survival analysis identified age, smoking history, tumor size, pT status, pN status, NLR, PLR, fibrinogen, albumin, AFR, and AGR as factors associated with overall survival. Multivariate analysis indicated that preoperative AFR (HR: 0.690, 95% CI = 0.495~0.960, P = 0.028), rather than other inflammation- and nutrition-based scores, was an independent predictor of overall survival. The C-index of the predicted nomogram containing AFR (C-index = 0.677) was higher than that of the nomogram without AFR (C-index = 0.656). The calibration curves showed that the predictive abilities were consistent with the actual observation results. Moreover, compared with the traditional staging system, the results of DCA showed that the nomogram had superior predictive ability and higher clinical utility.

Conclusion: Our preliminary study suggested that a low preoperative AFR might be a novel and valuable predictor of poor prognosis in patients with ESCC, which may be helpful for prognosis assessment, patient counseling, and therapeutic modality selection.
