T-Cell Activation in Patients With Irritable Bowel Syndrome
Abstract
OBJECTIVES: Irritable bowel syndrome (IBS) has been found to be associated with low-grade immune activation in a subset of patients. We therefore investigated blood and colonic T-cell activity in IBS patients. METHODS: Blood samples were initially obtained from 74 IBS patients and 30 controls. Supplementary blood samples, to confirm data, were taken from another cohort (26 patients and 14 controls). In addition, colonic biopsies were taken from a third cohort (11 patients and 10 controls). Peripheral blood and colonic mononuclear cells were stimulated with anti-CD3/CD28 antibodies. Proliferation, cytokine secretion, and T-cell phenotype were investigated. IBS symptom severity was assessed. RESULTS: IBS patients displayed an activated phenotype with increased frequencies of blood T cells expressing CD69 and integrin beta7/HLA-DR. Anti-CD3/CD28-stimulated blood and colonic T cells from IBS patients proliferated less than T cells from controls. IBS patients had an increased polyclonally stimulated T-cell secretion of IL-1beta, which also weakly correlated with increased bowel habit dissatisfaction. Furthermore, despite normal frequencies of CD25high T cells in the blood of IBS patients, lower blood CD25high T-cell frequencies were modestly correlated with more bowel habit dissatisfaction and increased total IBS symptom severity. CONCLUSIONS: IBS patients have an increased frequency of activated T cells, demonstrated by the expression of activation markers and reduced proliferation in response to restimulation in vitro. The increased level of T-cell activation is consistent with the hypothesis of low-grade immune activation in IBS and may also be involved in symptom generation in IBS.

“Overall, it seems that alterations in cytokine secretion by stimulated peripheral blood cells appear to favor an activated immune state (98, 122), and an altered immune response shifted toward a T-helper 2 phenotype(90) in IBS patients.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
