Orocaecal transit was also evaluated for each subject using the lactulose/hydrogen breath test. There was a fourfold increase in permeability to disaccharide (cellobiose) in patients with cystic fibrosis, but permeability to the monosaccharide (mannitol) was similar to controls. The orocaecal transit time of lactulose was prolonged in patients with cystic fibrosis, but was unrelated to the percentage excretion of cellobiose or mannitol in cystic fibrosis patients or control subjects.
