Inhibition of interleukin-12 and/or interleukin-23 for the treatment of psoriasis: What is the evidence for an effect on malignancy?

ABSTRACT: Immune cells and cytokines play an important role in the pathogenesis of psoriasis. Interleukin-12 (IL-12) and IL-23 promote cellular responses mediated by T cells, which contribute to an inflammatory loop responsible for the induction and maintenance of psoriatic plaques. Antibodies that inhibit IL-12/23 or IL-23 are key treatment options for patients with psoriasis. IL-12 and IL-23 also play a key role in immune responses to infections and tumors. A growing body of information from clinical trials, cohort studies, postmarketing reports, genetic studies and animal models provides insights into the potential biological relationships between IL-12/23 inhibition and malignancies. We summarize this information in tables and provide some context for the interpretation of these data with the goal of informing dermatologists who are using IL-12/23 or IL-23 inhibitors to treat patients with psoriasis.

Project description:Inflammatory bowel diseases (IBD) and psoriasis are chronic inflammatory conditions belonging to the heterogeneous group of immune-mediated inflammatory diseases (IMIDs). A significant bidirectional link between these two entities has been observed, conditioning an increased risk of IBD in patients with psoriasis and vice-versa. Biological therapies used for IBD may lead to the occurrence of psoriasis as a "paradoxical reaction." The objective of this study is to analyze the current evidence on the association between psoriasis and IBD, particularly finding case reports of the appearance or aggravation of psoriasis under therapy with interleukin-12/23 (IL-12/23) and IL-23 inhibitors. We conducted comprehensive research to identify studies examining the association between psoriasis and IBD and to find case presentations that reported the appearance or aggravation of psoriasis under biologic therapy with IL-12/23 and IL-23 inhibitors up to March 2024. Clinical trials for IL-12/23 and IL-23 inhibitors in IBD were analyzed to find cases of paradoxical psoriasis as registered adverse events. The sources of evidence are PubMed and ClinicalTrials.gov. For each included case report, data on patient characteristics concerning their age, sex, and comorbidities were selected. Moreover, information regarding the indication for biologic therapy, time to onset of paradoxical psoriasis after starting treatment, clinical presentation, and management of the paradoxical psoriasis was extracted. We found 10 reported cases of ustekinumab-induced new-onset or worsening psoriasis and one reported case of paradoxical psoriasis induced by risankizumab in the literature. Four cases of paradoxical psoriasis have been also registered in clinical trials involving ustekinumab treatment in IBD. Psoriasis can constitute a rare paradoxical adverse event of ustekinumab treatment, but further studies are needed to better clarify the cytokine imbalance that leads to this phenomenon induced by inhibition of IL-12/23 and IL-23. Still, few real-world data exist to draw any conclusions, but risankizumab may positively treat psoriasis induced by ustekinumab.
