Patients with cryptosporidiosis differed significantly from controls (135 (35) minutes, p&lt;0.0001), seven of 10 having rapid transit times. Absorptive capacity was reduced and intestinal permeability significantly increased in AIDS, but did not correlate significantly with transit times.<\/jats:p>\n                  <\/jats:sec>\n
