title: Peptide excretion in celiac disease.
abstract: BACKGROUND
  In celiac disease, the mucosa in the small intestine is damaged. This study was conducted to determine whether the normal peptide and protein uptake from the gut is increased in patients with celiac disease.
  
  
  METHODS
  The low-molecular-weight peptides were measured in urine from children and adults with untreated celiac disease. A reversed-phase technique was used.
  
  
  RESULTS
  The excretion of peptides increased compared with that in an age- and sex-matched reference group.
  
  
  CONCLUSIONS
  Celiac patients have hyperpeptiduria. It is possible that some of these peptides are bioactive and may mediate varying systemic effects also found in untreated celiac disease.
