MedicalResearch.com: What is the background for this study?
Response: Psoriasis is a chronic, immune mediated skin disease for which effective targeted biological agents have become available the past years. Inherent to their immunomodulatory mechanism of action, biologics might increase infections risk. We know from clinical trial data that respiratory tract infections are among the most common adverse events during biologic treatment, but real-world data is sparse. Regarding the risk of serious infections among biologic users, mostly defined as infections requiring hospitalization, previous studies provided different results and there is limited comparative data for the newer biologics available.
The COVID-19 pandemic turned attention to the risk of infections among biologic users, especially for respiratory tract infections, as they might relate to susceptibility for viral respiratory tract infections such as COVID-19.
In our study, the primary aim was to determine the risk of respiratory tract infections among real-world psoriasis patients treated with biologics, including the newer IL-17 and IL-23 inhibitors. The secondary aim was to assess risk of serious infections in this cohort. Additionally, rates of SARS-CoV-2 infections were assessed.

Isabelle Cleynen PhD

Medical Research: What is the background for this study? What are the main findings?
Dr. Cleynen : Ulcerative colitis and Crohn’s disease, together inflammatory bowel disease (IBD), are characterized by chronic inflammation of the gastrointestinal tract. Treatment for IBD usually involves drug therapy including anti-inflammatory drugs and immune system repressors, amongst which biologics as the anti-TNF antibodies used for patients with moderate to severe IBD. Although these TNF-blocking drugs are effective in many patients with immune-mediated disorders like psoriasis, rheumatoid arthritis and spondylarthropathies, and IBD, several case reports and series showed that some patients developed troubling skin problems (including psoriasis and eczema), causing them to stop the anti-TNF treatment. It is however not clear how often these skin problems develop in IBD patients treated with anti-TNF, and what could be the predisposing factors.
