title: Serum group I pepsinogens level in cystic fibrosis.
abstract: Fasting serum pepsinogen 1 level was determined by radioimmunoassay in 30 patients with cystic fibrosis and in on equal number of age-matched healthy children. Serum pepsinogen 1 basal levels were significantly higher (49 +/- 18 ng/ml; p less than 0.01) in cystic fibrosis patients than in controls (38 +/- 12 ng/ml). The increased pepsinogen 1 level did not correlate with the levels of Po2 and Pco2 tensions, fat balance or basal and maximum acid outputs. It is concluded that the mechanisms which lead to a rise of serum pepsinogen 1 in cystic fibrosis are unknown. However these findings could provide useful information with regard to the biology of a disease whose physiopathology is still unknown.
