TOPLINE:
Skin conditions burden many children with inflammatory bowel disease (IBD), found single-center study.
METHODOLOGY:
- Little is known about the prevalence of IBD-associated skin lesions and their association with IBD severity in children ages 18 and younger.
- Researchers retrospectively reviewed the medical charts of 425 children and adolescents with Crohn's disease (CD) or ulcerative colitis (UC) at one or more dermatologic diagnoses who were seen at Mayo Clinic, Rochester, Minnesota, between 1999 and 2017.
- Of the children studied, 53% were male, 64.9% had CD, and 42.8% had one or more cutaneous infections.
- They used the chi-square/Fischer's exact test to compare categorical outcomes between patients with CD and UC and to detect differences in IBD/CD/UC disease severity and skin conditions.
TAKEAWAY:
- The most common noninfectious dermatologic condition among the 425 children and adolescents was acne (30.8%), followed by eczema (15.8%) and perianal skin tags (14.6%).
- Angular cheilitis was more common among those with CD than those with UC (7.2% vs 2%, respectively; P = .024) as was keratosis pilaris (6.9% vs 0.7%; P = .003), and perianal skin complications such as skin tags (20.3% vs 4%), fistulas (13.4% vs 2.7%), and abscesses (13.4% vs 2%; P < .001 for all associations).
- Fungal skin infections were more frequently diagnosed in children with UC than those with CD (15.4% vs 8%; P = .017).
- The researchers observed that the severity of IBD correlated with a higher prevalence of perianal fistula (P = .003), perianal region abscess (P = .041), psoriasis (P < .001), and pyoderma gangrenosum (P = .003).
IN PRACTICE:
"Early identification of common dermatologic conditions in children and adolescents with IBD and recognizing their characteristic associations may alter management and improve skin-related outcomes in this patient population," the authors wrote.

LIMITATIONS:
The single-center design and the fact that database studies are subject to extraction error. There was no age- and sex-matched cohort to determine whether the prevalence of cutaneous infections, acne, eczema, and other inflammatory disorders was truly increased in IBD.
DISCLOSURES:
The researchers reported having no disclosures.
