title: Intestinal permeability test in systemic lupus erythematosus.
abstract: Using the Cr-51 labeled EDTA resorption test, intestinal permeability was measured in 23 patients with systemic lupus erythematosus and in 16 healthy volunteers. The Cr-51 EDTA intestinal permeability test was adopted from Bjarnason et al, (Gastroenterology 1983; 85:318). 87% (14/16) of the controls had an abnormal permeability test findings (more than 2.6% in 24h). No significant difference was demonstrated between the SLE patients and the controls (SLE = 3.51 +/- 1.66; controls = 4.20 +/- 1.56, P greater than 0.05). Our study indicated that Cr-51 EDTA permeability test failed to distinguish between SLE and normal groups, and that the elevated Cr-51 EDTA excretion in the controls challenged the validity of the test.
