Abstract
To determine whether plasma endothelin-1 (ET-1) relates to clinical manifestations of sepsis in the newborn, especially with systemic hypotension, acidosis, severe hypoxemia (which may represent pulmonary hypertension) and oliguria. Prospective study of 35 consecutive newborns with clinical sepsis: 22 with hemoculture-positive (HC+) sepsis and 13 hemoculture-negative (HC-). Plasma ET-1 concentrations were measured within 2 days of the diagnosis of sepsis. SNAP-II severity score was performed at the time of highest clinical severity. Newborns with HC+ sepsis had higher plasma ET-1 concentrations and SNAP-II scores (especially PO 2 /FiO 2 ratio) than HC- septic children. Plasma ET-1 concentrations increased linearly with each item of the SNAP-II score, but only reached significant differences in lowest mean blood pressure (P=0.030), lowest pH (P=0.048), multiple seizures (P=0.010) and lowest urine output (P=0.013). Leukocyte count, immature/total neutrophil ratio and C-reactive protein value were not different. Each item of the SNAP-II score was independently related only to ET-1 level. Oliguria, acidosis and systemic hypotension were more correlated (R 2 >0.5). Plasma ET-1 levels in neonatal sepsis are related to the severity of clinical manifestations, especially oliguria, acidosis and systemic hypotension.
