This cross-sectional study included 41 children (age 2 mo-12 y)
with pneumonia and 40 healthy controls. Assay of serum
copeptin was done using ELISA. Median serum copeptin levels
were significantly higher (P=0.03) in children with pneumonia, and
in those who died (P=0.04). We conclude that serum copeptin
levels seem to be associated with poor outcome in pneumonia.
