From: Lack of autoantibodies against collagen and related proteins in collagenous colitis
Levels of collagen-associated antibodies in patients with collagenous colitis and controls. Col III = collagen type III, Col IV = collagen type IV, MMP-9 = matrix metalloproteinase-9, TIMP-1 = tissue inhibitors of metalloproteinases-1, TNC = tenascin-C. CC = collagenous colitis (n = 66); treated = current budesonide treatment, controls = healthy blood donors (n = a 70, b 51, c 100, d 65, e 100). Black bars state median values. Y axis: Antibody levels in relative units (RU) (absorbance values after subtracted background). Cut-off value set at the 97.5 th percentile. Fischer's exact test was used to calculate the differences between controls and CC pat (including both treated and untreated)
