Infection and infestation-related adverse events of biologics in psoriasis: insights from the food and drug administration adverse event reporting system (FAERS)

Abstract

ABSTRACT Objective The study aims to thoroughly assess the adverse events related to infections and infestations associated with biological agents used for psoriasis using the U.S. Food and Drug Administration’s Adverse Event Reporting System (FAERS) database. Methods We analyzed FAERS data from the first quarter of 2004 to the fourth quarter of 2023. The study included TNF-α inhibitors (etanercept, infliximab, adalimumab), IL-12/23 inhibitors (ustekinumab), IL-23p19 inhibitors (guselkumab), and IL-17 inhibitors (secukinumab, ixekizumab). We used disproportionality analysis and Bayesian methods to quantify the related adverse event (AE) signals. Results Most AEs related to infections and infestations are already listed on the drug packaging labels. Notably, TNF-α inhibitors are associated with a significantly higher incidence of tuberculosis-related diseases compared to other biological agents. In contrast, IL-17 inhibitors show a greater variety and number of fungal infection-related AEs than their counterparts. Furthermore, our study has identified new potential AEs that require the attention of clinicians. Conclusion In clinical practice, it is advisable to monitor the risks of infections and infestations in patients receiving biological agents for psoriasis to enable early detection and intervention. Our findings highlight the need for further epidemiological investigations to establish causality and guide clinical practice in managing these risks effectively.
