ABSTRACT: BACKGROUND: Hidradenitis suppurativa (HS) and pyoderma gangrenosum (PG) are reported to coexist, although the prevalence of PG among patients with HS has not been systematically evaluated. OBJECTIVE: To evaluate PG prevalence among patients with HS. METHODS: Cross-sectional analysis of adults with PG among patients with HS and patients without HS through use of electronic health records data from a population-based sample of 55 million patients. RESULTS: The prevalence of PG among 68,232 patients with HS was 0.18% (125 of 68,232), compared with 0.01% (1835 of 31,435,166) among those without HS (P < .0001). Prevalence was markedly higher among patients with HS and Crohn's disease (CD) (3.68%) than among patients with HS but without CD (0.12%). The odds of having PG were 21.14 (95% confidence interval [CI], 17.51-25.51) times greater among patients with HS than among those without HS. Patients with HS with CD had 12.38 (95% CI, 9.15-16.74) times the odds of having PG than did patients without HS but with CD. Among patients without CD, compared with patients without HS, those with HS had 26.51 (95% CI, 21.07-33.36) times the odds of having PG. LIMITATIONS: We could not establish HS phenotype among those having coexistent PG, nor could we distinguish syndromic from nonsyndromic cases. CONCLUSION: Patients with HS have an increased prevalence of PG, regardless of CD status. Painful ulcerations among patients with HS warrant additional evaluation for PG.

2 Article Overall and Subgroup Prevalence of Crohn Disease Among Patients With Hidradenitis Suppurativa: A Population-Based Analysis in the United States. 2018

ABSTRACT: Importance: Limited evidence supports a link between hidradenitis suppurativa (HS) and Crohn disease (CD), and this relationship has not been established in the United States. Objective: To evaluate the prevalence of CD among patients with HS in the United States and to determine the strength of association between the 2 conditions. Design, Setting, and Participants: Cross-sectional analysis of data from 51 340 patients with HS identified using electronic health records data in the Explorys multiple health system data analytics and research platform, which includes data from more than 50 million unique patients across all US census regions. Main Outcomes and Measures: Primary outcome was diagnosis of CD. Results: Of the 18 455 660 total population considered, 51 340 had HS (35 000 women). Of these patients with HS, 29 010 (56.5%) were aged 18 to 44 years; 17 580 (34,2%), 45 to 64 years; and 4750 (9.3%), 65 years or older. Prevalence of CD among patients with HS was 2.0% (1025/51 340), compared with 0.6% (113 360/18 404 260) among those without HS (P < .001). Prevalence of CD was greatest among patients with HS who were white (2.3%), aged 45 to 64 years (2.4%), nonobese (2.8%), and tobacco smokers (2.3%). In univariable and multivariable analyses, patients with HS had 3.29 (95% CI, 3.09-3.50) and 3.05 (95% CI, 2.87-3.25) times the odds of having CD, respectively, compared with patients without HS. Crohn disease was associated with HS across all patient subgroups. The association was strongest for men (OR, 3.61; 95% CI, 3.24-4.03), patients aged 45 to 64 years (OR, 3.49; 95% CI, 3.16-3.85), nonobese patients (OR, 4.09; 95% CI, 3.69-4.54), and nonsmokers (OR, 3.44; 95% CI, 3.10-3.82). Conclusions and Relevance: These data suggest that patients with HS are at risk for CD. Gastrointestinal symptoms or signs suggestive of CD warrant additional evaluation by a gastroenterologist.
