Infliximab Paradoxical Psoriasis in a Cohort of Children With Inflammatory Bowel Disease

Abstract: Objectives: In adult inflammatory bowel disease (IBD) treated by anti-TNF antibodies, paradoxical psoriasis has an estimated prevalence of 1.6 to 22%, especially in infliximab (IFX)-treated patients. Little is known in the pediatric IBD (PIBD) populations. Methods: All patients ages from 2 to 18 years with Crohn disease (CD) or ulcerative colitis (UC) and treated for the first time by IFX between January 2002 and March 2014, were considered for inclusio… Show more

“…There are significant differences in the incidence of psoriasis in the different genders in the pediatric group (7-17 years) treated with IFX [46]. And in most cohort studies of pediatric patients, TNF antagonist induced psoriasis is more predisposed to the female population [18,48]. In our study, OR Teenager group is higher than OR Adult group in the analysis of the association between different gender groups.…”

“…In this data-mining study of adverse events of TNF-α inhibitors in pediatric patients based on the nationwide Danish population, we found no signals of previously unknown adverse events. A signal of dermatologic complications that has been previously described in adults and children was detected, including excess cases of diseases of the skin and subcutaneous tissue, and dermatitis and eczema [21][22][23][24][25][26]. A detected signal of psychiatric diagnoses of anxiety, dissociative, stress-related, somatoform, and other nonpsychotic mental disorders, including reaction to severe stress and adjustment disorders, was likely associated with the underlying disease and its severity, rather than with the treatment.…”

“…In one retrospective study, Courbette et al highlighted that the median time of paradoxical psoriasis appearance in children treated with Infliximab was after the eighth infection which corresponded to 355 days (from the moment of treatment initiation). In this study, psoriasis occurred in CD patients only, and it was associated with perianal lesions suggesting that perianal lesions represent a risk factor for psoriasis in CD patients [ 35 ].…”

“…Also, it seems that polymorphism in the IL-23R gene may have a role in the development of paradoxical infliximab-induced psoriasis. The association between psoriasis and perianal lesions in CD patients has not been established but it seems that they share a cutaneous immune response [ 35 ].…”
