Background: Disturbances in bowel function in chronic constipation could result in changes in the colonic flora and lead to disordered immunity and to decreased resistance to pathogenic flora.
Aim: To investigate systemic immunity, the faecal flora and intestinal permeability in patients with chronic constipation, under basal conditions and following therapy with the laxative Bisacodyl.
Methods: Intestinal permeability, faecal flora analysis, T- and B-lymphocyte numbers, T-cell subpopulations, lymphocyte proliferation, phagocytosis, intracellular killing of Staphylococcus aureus by neutrophils, as well as circulating levels of immunoglobulins, immune complexes and antibacterial antibodies were assessed in 57 patients with functional constipation.
