Study Describes Skin Conditions in Down Syndrome

TOPLINE:
Eczematous dermatitis, folliculitis, and seborrheic dermatitis were the most common skin conditions in patients with Down syndrome (DS) in a 10-year retrospective review.
METHODOLOGY:
Researchers conducted a multicenter retrospective study of 1529 patients with DS from eight outpatient dermatology clinics in the United States and Canada between 2011 and 2021.
In total, 50.8% of patients were children (0-12 years), 25.2% were adolescents (13-17 years), and 24% were adults (≥ 18 years).
The researchers evaluated skin conditions in the patients.
TAKEAWAY:
Eczematous dermatitis was the most common diagnosis, affecting 26% of patients, followed by folliculitis (19.3%) and seborrheic dermatitis (15.6%). Dermatophyte infections were diagnosed in 13%.
Alopecia areata was the most common autoimmune skin condition, diagnosed in 178 patients (11.6%); 135 (75.8%) were children. Vitiligo was diagnosed in 66 patients (4.3%).
The most common cutaneous infections were onychomycosis (5.9%), tinea pedis (5%), and verruca vulgaris/other viral warts (5%).
High-risk medication use was reported in 4.3% of patients; acne vulgaris, hidradenitis suppurativa, and eczematous dermatitis were the most common associated conditions with such medications.
IN PRACTICE:
“Children, adolescents, and adults with DS are most often found to have eczematous, adnexal, and autoimmune skin conditions at outpatient dermatology visits,” the authors wrote. Their findings, they added, “offer valuable insights for clinicians and researchers, aiding in the improved prioritization of screening, diagnosis, and management, as well as facilitating both basic science and clinical research into prevalent skin conditions in individuals with DS.”
SOURCE:
The study was led by Tasya Rakasiwi, of the Department of Dermatology, Dartmouth Health, Manchester, New Hampshire, and was published online on September 26 in Pediatric Dermatology.
LIMITATIONS:
Over 50% of the patients were children, potentially resulting in bias toward pediatric diagnoses and younger ages of presentation. Race, ethnicity, and sociodemographic factors were not captured, limiting the generalizability of the findings. Medical codes often do not capture disease phenotype or severity, and the manual conversion of International Classification of Diseases (ICD) 9 to ICD-10 codes may introduce potential conversion errors.
DISCLOSURES:
The study was supported by the Pediatric Dermatology Research Alliance. The authors declared no competing interests.
