Immunoglobulin-containing cells in the colonic mucosa in patients with human intestinal spirochaetosis.
The relative proportions of cells containing the various classes of immunoglobulins in the colonic mucosa were determined in eight patients with human intestinal spirochaetosis (HIS) and in eight controls. All specimens were taken from colonic resections performed because of adenocarcinoma. None of the cases with HIS showed an inflammatory reaction in the mucosa as judged subjectively by light microscopy. Cases with HIS had smaller proportions of IgD- and IgE-positive cells and a larger proportion of IgA cells as compared with the controls, whereas the proportions of IgG and IgM cells were similar in the two groups. Taking into account the large individual variations in the proportions of immunoglobulins in both groups, our findings must be interpreted with caution. However, our results do not support the previous demonstration of increased percentages of IgE-positive cells in patients with HIS.
