Abstract

Background and Aims:Inflammatory bowel disease (IBD) is a typical polygenic disorder and less frequently shows a monogenic origin. Furthermore, IBD can originate in the context of specific genetic syndromes associated with a risk of autoimmune disorders. We aimed to systematically evaluate the prevalence of IBD in specific genetic syndromes and to review the clinical characteristics of the published cases. Methods:According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, studies describing patients with IBD and a genetic syndrome and/or studies indicating the prevalence or incidence of IBD in subjects with a genetic syndrome were included. Results:Forty-six studies describing a total of 67 cases of IBD in six genetic syndromes and two personally assessed unpublished cases were included in the review. The majority of cases were associated with Turner syndrome (TS) (38 cases), Down syndrome (DS) (18 cases) and neurofibromatosis type 1 (NF1) (8 cases). Sporadic cases were described in DiGeorge syndrome (2), Kabuki syndrome (2), and Williams syndrome (1). The prevalence of IBD ranged from 0.67 to 4% in TS and from 0.2 to 1.57% in DS. The incidence of IBD was increased in TS and DS compared to the general population. Eight cases of IBD in TS had a severe/lethal course, many of which described before the year 2000. Two IBD cases in DS were particularly severe. Conclusion:Evidence of a greater prevalence of IBD is accumulating in TS, DS, and NF1. Management of IBD in patients with these genetic conditions should consider the presence of comorbidities and possible drug toxicities.

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

  • IBD in TS may present at a younger age (mean 17.8 ± 2.3 years, range 3-41 years).

    “IBD in TS may also present at a younger age (mean 17.8 ± 2.3 years, range 3-41 years),728 be more severe,729 and/or have unique treatment complications,732 although there is likely reporting bias.”
  • A previous systematic review reported a prevalence range of IBD in TS between 0.67% and 4%.

    “A 2023 meta-analysis found an increased expressivity of IBD in TS of 1.86% (95% CI 1.48%-2.34%),728 congruent with the findings in a previous systematic review reporting a prevalence range between 0.67% and 4%.729”
  • A systematic review of 25 cases in the literature found equal distribution of IBD between monosomy and structurally abnormal X chromosomes.

    “Unlike previous studies reporting higher rates of IBD among patients with isochromosome Xq karyotype,730,731 a systematic review of 25 cases in the literature found equal distribution between monosomy and structurally abnormal X chromosomes.729”

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.
