Atopic dermatitis is associated with an increased risk for rheumatoid arthritis and inflammatory bowel disease, and a decreased risk for type 1 diabetes
Open accessAbstract
Background Atopic dermatitis (AD) is characterized by epidermal barrier failure and immune-mediated inflammation. Evidence on AD as a potential risk factor for inflammatory comorbidities is scarce. Objectives We sought to test the hypothesis that prevalent AD is a risk factor for incident rheumatoid arthritis (RA) and inflammatory bowel disease (IBD; Crohn disease [CD], ulcerative colitis [UC]) and is inversely related to type 1 diabetes (T1D) and to investigate established RA, IBD, and T1D susceptibility loci in AD. Methods This cohort study used data from German National Health Insurance beneficiaries aged 40 years or younger (n = 655,815) from 2005 through 2011. Prevalent AD in the period 2005 to 2006 was defined as primary exposure, and incident RA, IBD, and T1D in the period 2007 to 2011 were defined as primary outcomes. Risk ratios were calculated with generalized linear models. Established RA, IBD, and T1D loci were explored in high-density genotyping data from 2,425 cases with AD and 5,449 controls. Results Patients with AD (n = 49,847) were at increased risk for incident RA (risk ratio [RR], 1.72; 95% CI, 1.25-2.37) and/or IBD (CD: RR, 1.34; 95% CI, 1.11-1.61; UC: RR, 1.25; 95% CI, 1.03-1.53). After adjusting for health care utilization, there was a nominally significant inverse effect on T1D risk (RR, 0.72; 95% CI, 0.53-0.998). There was no disproportionate occurrence of known RA, CD, UC, or T1D risk alleles in AD. Conclusions AD is a risk factor for the development of RA and IBD. This excess comorbidity cannot be attributed to major known IBD and RA genetic risk factors.

These results suggest that overall genetic correlations may obscure a more complex set of genetic relationships at the level of specific loci and pathways.
“These results underscore the complexity of genetic relationships among related disorders and suggest that overall genetic correlations may obscure a more complex set of genetic relationships at the level of specific loci and pathways, as seen in immune-mediated diseases (Baurecht et al., 2015; Lettre and Rioux, 2008; Schmitt et al., 2016).”

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.
