Hypoalbuminemia may predispose infants to necrotizing enterocolitis

Numerous risk factors for necrotizing enterocolitis (NEC) including prematurity, bowel ischemia, pathogenic bacteria, and hyperosmolar feedings have been proposed. Recent studies have demonstrated feeding intolerance and bowel dysfunction in children with hypoalbuminemia. No association between hypoalbuminemia and NEC has been suggested. The records of 45 patients with NEC and complete documentation of prenatal and birth histories were reviewed. A control (CONT) group of 90 children matched for maternal age (+/- 1 year), parity, gestational age (+/- 1 week), birth weight (+/- 20 g), type of delivery, sex, race, type of initial feeding, and perinatal stress was compiled. While all other measured parameters were similar in the two groups, premorbid albumin was significantly lower in the patients who subsequently developed NEC (P less than .001). These data suggest that newborns with hypoalbuminemia may have an increased risk of developing NEC.
