Serum albumin, a good indicator of persistent organ failure in acute pancreatitis

Abstract

Abstract Background To evaluate the predictive value of serum albumin (ALB) for persistent organ failure (POF) in acute pancreatitis (AP). Methods We selected 158 patients with AP in this retrospective study from Jan.1st, 2015 to Dec.31st, 2015. Forty-six patients were diagnosed with POF. All the values of laboratory parameters were measured upon admission to hospital. And 48 h after admission, we examined serum albumin of each patient again, called ‘ALB2’. Uni-and multi-variate logistic regression were used to evaluate the impact of ALB to predict POF. Results The median age of the whole population was 48 years and 53.8% were male. The admission-time albumin of AP patients with POF was distinctly lower than patients without POF (28.9 (25.3–33.1) g/L vs. 38.5 (34.0–40.1) g/L, p < 0.001). In uni-variate analysis, WBC, PT, GLU, LDH, ALB, ALB2, BUN, Ca, HDL-C and Ranson were significantly associated with POF. After multivariate regression, ALB remained an independent prognostic factor for POF in AP (OR: 0.748, 95%CI: 0.645–0.868; p < 0.05). The AUC for ALB is 0.873 (0.808, 0.938), even larger than that for Ranson, 0.845 (0.634, 0.913). Conclusions We identified serum albumin predictive to persistent organ failure in acute pancreatitis.
