Recent advances in hidradenitis suppurativa in pediatrics

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that can cause significant physical, mental, and socioeconomic burden. There remains a paucity of literature on HS in the pediatric population. This systematic review highlights recent advances in pediatric HS in epidemiology, presentation, comorbidities, and management. PubMed, Embase, Google Scholar, and Clinicaltrials.gov databases were used to identify trials and articles published on HS in pediatric patients between January 2015 and October 2019. A total of 39 articles were included. Current evidence suggests that pediatric onset HS may be associated with genetic factors along with endocrine and metabolic abnormalities. Delayed diagnosis in children with HS contributes to poor outcomes. Overall, children and adults with HS share similar lesion types and involved areas. Pediatric HS is associated with a number of comorbid conditions including acne, obesity, inflammatory joint disease, Down syndrome, inflammatory bowel disease, and diabetes. There are currently no pediatric treatment guidelines. Adalimumab is approved for the treatment of moderate-to-severe HS in children 12 and older. Other targeted immunomodulators and hormonal modulators are under investigation. Although the number of studies concerning HS are increasing, further investigation is warranted to better characterize HS, facilitate early diagnosis, and determine the best management for children.
