Ischemia-Modified Albumin May be a Novel Marker for the Diagnosis and Follow-up of Necrotizing Enterocolitis (original) (raw)

2014, Journal of Clinical Laboratory Analysis

Aim: We investigate the efficacy of serial ischemia-modified albumin (IMA) measurements in diagnosis and follow-up of necrotizing enterocolitis (NEC), and compare its effectiveness with C-reactive protein (CRP), interleukin-6 (IL-6), in NEC. Methods: Preterm infants, whose gestational age and weight matched each other, were grouped as control (n = 36) and NEC (n = 37). IMA, CRP, IL-6 levels were measured on the third day of life for the control group and on the day of diagnosis (first day), third, and seventh days of NEC. Results: IMA, CRP, and IL-6 levels were significantly increased in NEC patients compared to the control group (P < 0.001) on the follow-up. IMA levels were significantly higher in infants with stage-III NEC than those in infants with stage-II NEC on the first, third, and seventh days (P < 0.001). The area under curve for IMA (0.815 at diagnosis, 0.933 at the third day, 0.935 at the seventh day) were significantly higher than CRP and IL-6 at all days for predicting perforation in infants with NEC (P < 0.001). Similarly, the area under curve for IMA (0.952 at diagnosis, 0.929 at the third day, 0.971 at the seventh day) was significantly higher than CRP and IL-6 at all consequent days of diagnosis for predicting mortality in infants with NEC (P < 0.001). Conclusion: Ischemia-modified albumin was found to be superior to CRP and IL-6 in both diagnosis and follow-up of NEC.
