Background: The C-reactive protein to albumin ratio (CAR) is a novel inflammation index that has recently been used as a marker for poor prognosis or mortality in various patient groups. This study aimed to evaluate the association between the CAR and 30-day mortality in patients with hepatitis B virus-related decompensated cirrhosis (HBV-DeCi).
Methods: This was a retrospective cohort study of 113 patients who had been diagnosed with HBV-DeCi. Univariate and multivariate regression models were used to determine risk factors for mortality.
Results: The CAR was observed to be significantly higher in the non-surviving patients compared to the surviving patients. Moreover, the CAR was positively correlated with the model for end-stage liver disease (MELD) score and Child-Pugh score. In multivariate analysis, the CAR and the MELD score were independent prognostic factors for HBV-DeCi patients.
Conclusions: A high CAR value at admission can serve as an independent predictor of 1-month mortality in patients with HBV-DeCi.
