Abstract
Fetal inflammatory response syndrome is implicated as a cause of fetal or neonatal injury. We analyzed the relationship between the procalcitonin umbilical cord blood level and neonatal outcome. A total of 237 preterms born in a level III perinatal medicine unit of a French university hospital were enrolled in a prospective observational study. Measurement of the procalcitonin umbilical cord blood level was performed at birth. After hospitalization, surviving infants were enrolled in the regional follow-up program. Outcome data were recorded on standardized questionnaires. The main outcome measures were neonatal mortality and impaired functional outcome at 2 years of corrected age. The terciles of procalcitonin levels were calculated. Preterm infants of the third tercile were defined as infants with elevated procalcitonin. Among the 237 infants, 13 (5.5%) died during the neonatal period, 20 (8.4%) were lost to follow-up, and 31 (13.1%) were classified as having an impaired functional outcome. After adjustment, elevated cord blood procalcitonin (>0.33 ng/ml) was significantly associated with an increase in mortality (adjusted odds ratio [aOR] = 8.3 [1.4–48]; p = 0.018), but not with the 2-year impaired functional outcome (aOR = 1.0 [0.4–2.5]; p = 0.93). Elevated umbilical blood cord procalcitonin concentration is an independent risk factor of mortality in preterm infants at less than 33 weeks’ gestation.
