We have studied prospectively the usefulness of indium 111 granulocytes scanning in patients with Crohn's disease and ulcerative colitis. Abdominal scans were performed 1 h, 3 h and 20 h after the injection of a pure autologous granulocyte preparation containing 3.7-5.5 MBq of radioindium. The extent of bowel involvement, evaluated on the 3-hour scan, was compared to the X-rays and endoscopic findings. The disease activity was assessed by the intensity of intestinal radionuclide uptake (IRU), the fecal indium 111 measurement (FIM) after a 4-day fecal collection, the decrease of the hepatic and splenic uptake (DHSU). It was compared to clinical and biological data as CDAI, sedimentation rate, albumin and alpha-2-globulin levels. Thirty-three examinations were performed in 26 patients, 16 with Crohn's disease and 10 with ulcerative colitis. The correlation of disease location between indium scan and other diagnosis procedures was good in 81 p. 100 of cases. CDAI was significantly correlated with radionuclide indexes: IRU, FIM, DHSU. FIM was not significantly different between mild and moderates diseases (respectively 1.5 +/- 1.0 p. 100 and 3.6 +/- 3.2 p. 100), but was different between moderate and moderately severe diseases (respectively 3.6 +/- 3.2 p. 100 and 23.6 +/- 16.7 p. 100, p less than 0.001). DHSU was significantly different between mild and moderate diseases (respectively 10.9 +/- 7.2 p. 100 and 22.5 +/- 10.7 p. 100, p less than 0.05) and between moderate and moderately severe diseases (respectively 22.7 +/- 10.7 and 42.4 +/- 7.3 p. 100, p less than 0.001). The radionuclide activity indexes were significantly correlated between themselves.
