March 2013 in “Gut” In this study, 434 patients with inflammatory bowel disease (IBD) treated with anti-TNF-α antibodies were screened for psoriasiform skin lesions, with 21 (4.8%) developing such lesions. Smoking and increased body mass index were identified as significant predictors. Histological analysis revealed infiltrates of Th1 and Th17 cells in the lesions. Nine patients with severe lesions or anti-TNF-induced alopecia were treated with the anti-IL-12/IL-23 antibody ustekinumab, achieving a 100% response rate. The severity of lesions correlated with the number of IL-17A-expressing T cells. The study concluded that anti-IL-12/IL-23 antibody therapy is highly effective for treating these lesions.
