In a group of patients with chronic diarrhea of unknown origin, a study of cellular and humoral immunity was carried out with in vitro tests and the results are compared to those obtained in a group of patients with ulcerative colitis or Crohn's disease, and to normal controls. In the chronic diarrhea group there was evidence of an immunological deficiency affecting the B and T lymphocytes that had specific characters in relation to IgG, although the IgG deficit was not as important as in intestinal inflammatory disease. |
