Abstract

Systematic reports of antidepressant use in irritable bowel syndrome (IBS) first appeared in the medical literature three decades ago. Recent meta-analyses of the cumulative controlled experience confirm the efficacy of antidepressants in IBS and other functional gastrointestinal disorders: only 3–4 patients require treatment to demonstrate a benefit over placebo—numbers indicating a solid treatment effect.1–3 Although many of the earlier reports would be considered scientifically flawed by today’s standards, the effects are consistent across studies. Odds ratios of treatment over placebo for primary study outcome, global (or syndromic) response, and pain exceeded 4.0 for each determination in one analysis, and the effect sizes of antidepressant treatment on continuous outcome measures were large.3 These observations in conjunction with reported open label experience and general clinical success have given antidepressants an important position in the therapeutic armamentarium for IBS.4 Most studies have employed tricyclic antidepressants (TCAs), medications that appear to have benefits not necessarily shared across the antidepressant class. Daily dosages of TCAs (25–125 mg/day) that are below the psychiatric range for antidepressant effect typically are effective in IBS, producing at least a moderate response in more than 85% of patients in open label use.5 With the TCAs, onset of action is rapid, effects appear sustained without tachyphylaxis, and the benefits are unrelated …

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

  • A study of inflammatory bowel disease patients in clinical remission found that Rome II symptoms correlated with increased calprotectin, suggesting that occult inflammation may drive symptoms.

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.
