Observational studyHumans

Design
Observational study
Subjects
30 children with persistent wheezing and 30 age-matched infant controls
Dose used in the study
Not stated in the abstract; no treatment was given
Duration
2-year follow-up
What was measured
LC/MS metabolomic profile of bronchoalveolar lavage fluid; wheezing recurrence over 2 years.

What the authors reported

Children with persistent wheezing had a distinct lung metabolome, with higher choline, oleamide, butyrylcarnitine, palmitoylethanolamide and several phosphatidylcholines. Glycerophospholipid metabolism was the most relevant pathway, and among children with recurrence, those born prematurely had more butyrylcarnitine.

Limits of this study

An observational study that measured natural palmitoylethanolamide in lung fluid; it did not test PEA as a treatment and cannot show cause. Small sample. The authors declare no competing interests.
