Abstract

Interstitial cystitis (IC) is a relatively uncommon and enigmatic disorder characterized by pain in the bladder and pelvic region, typically accompanied by urinary urgency and frequency. Fibromyalgia is a more common disorder, with the prominent symptoms being diffuse musculoskeletal pain and fatigue, and it has been well established that there is substantial clinical overlap between fibromyalgia and chronic fatigue syndrome (CFS). Although genitourinary and musculoskeletal symptoms predominate in IC and fibromyalgia respectively, both disorders share a number of features, including similar demographics, "allied conditions" (e.g. irritable bowel syndrome, headaches, etc.), natural history, aggravating factors, and efficacious therapy. We hypothesized that there was substantial clinical overlap between fibromyalgia and IC, and examined cohorts of individuals with these two disorders in parallel, to compare the spectrum of symptomatology. Sixty fibromyalgia patients, 30 IC patients, and 30 age-matched healthy controls were questioned regarding current symptomatology. A dolorimeter examination was also performed in the three groups to assess peripheral nociception. We found that the frequency of current symptoms was very similar for the fibromyalgia and IC groups. Both the fibromyalgia and IC patients displayed increased pain sensitivity when compared to healthy individuals, at both tender and control points. These data suggest that IC and fibromyalgia have significant overlap in symptomatology, and that IC patients display diffusely increased peripheral nociception, as is seen in fibromyalgia. Although central mechanisms have been suspected to contribute to the pathogenesis of fibromyalgia for some time, we speculate that these same types of mechanisms may be operative in IC, which has traditionally been felt to be a bladder disorder.

Claims other papers make about this one

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

  • Interstitial cystitis is considered a central sensitization syndrome.

    “Accordingly, and due also to the similarities of the symptoms with CSS, IC is also considered a CSS [9,49].”

    From Effectiveness of acceptance and commitment therapy in central pain sensitization syndromes: A systematic review (2021) · cites this paper as [49]

    The Discussion reports symptom overlap and increased pain sensitivity in IC, and suggests that centrally mediated mechanisms may be partly responsible for its pain. The Abstract likewise speculates that central mechanisms may operate in IC. Neither passage establishes the categorical claim that IC is considered a central sensitization syndrome; page numbers were not available in our copy. (LLM, conf=0.87)

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.
