Does serum albumin at the onset of necrotisıng enterocolitis predict severe disease in preterm infants?

Abstract

Objective: To investigate whether laboratory markers obtained at the onset of necrotising enterocolitis (NEC) predict the severity of the disease in preterm infants.

Methods: Prospective cohort study conducted in a tertiary referance hospital. A total of 88 preterm infants were included in the study. Of those, 60 infants had the diagnosis of severe NEC, while the remaining 28 infants constituted the non-severe NEC group. Severe NEC was defined as surgical NEC or NEC-related mortality. Infants with and without severe NEC were compared in terms of demographic, clinical and laboratory characteristics.

Results: At the onset of disease, infants with severe NEC noted to have lower platelet count and serum ALB levels (p = 0.011, p = 0.004; respectively), whereas higher CRP, and serum lactate levels (p = 0.009, p = 0.008; respectively). Multiple binary logistic regression analyses showed that CRP (1.03(1.01-1.05), p = 0.024) and serum albumin level (0.16(0.04-0.64), p = 0.010) were statistically significant independent risk factors for severe NEC. The optimal cut-off value for the serum ALB level was found to be 23 g/L with 52% sensitivity (95%CI: 37-68%) and 84% specificity (95%CI: 60-97%) (AUC 0.727; p = 0.002).

Conclusion: Serum ALB level at NEC onset might be a reliable biomarker for severe disease in preterm infants.
