Abstract

OBJECTIVES: There is a move toward patient-reported outcome measures as end points in clinical trials of novel therapies for inflammatory bowel disease (IBD). However, the association between patient-reported symptoms and mucosal inflammation, and the influence of psychological factors, remains unclear. We examined this in a secondary care population. METHODS: Validated patient-reported disease activity indices were used to define clinically active disease in a cohort of 356 patients with ulcerative colitis (UC) or Crohn's disease (CD). A fecal calprotectin ≥250 μg/g was used to define active mucosal inflammation. The hospital anxiety and depression scale (HADS) and patient health questionnaire (PHQ)-15 were used to assess for anxiety, depression, or somatization, respectively. Logistic regression analysis was performed to determine the association between symptoms, mucosal inflammation, and psychological comorbidity. RESULTS: Clinical disease activity was associated with mucosal inflammation in UC (odds ratio (OR) 3.36; 95% confidence interval (CI) 1.34-8.47) but not in CD (OR 1.69; 95% CI 0.74-3.83). Depression in UC (OR 1.21 per 1-point increase in HADS; 95% CI 1.02-1.44) and somatization in UC (OR 1.17 per 1-point increase in PHQ-15; 95% CI 1.03-1.33) and CD (OR 1.31 per 1-point increase in PHQ-15; 95% CI 1.13-1.52) were associated with clinical disease activity. Overall, patient-reported symptoms yielded poor positive predictive values for mucosal inflammation in both CD and UC. CONCLUSIONS: Patient-reported symptoms and the Harvey-Bradshaw index were poor predictors of mucosal inflammation in CD. Psychological comorbidity was associated with gastrointestinal symptom-reporting. A shift in the focus of IBD management toward one addressing both psychological and physical well-being is required.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some of the association may relate to patients with IBD with symptoms of a common mental disorder being more likely to report gastrointestinal symptoms, and therefore meet criteria for a flare of IBD.

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.
