Recent research has drawn intriguing conclusions regarding the safety of biologic treatments for psoriasis and psoriatic arthritis (PsA) in older adults. A comprehensive study found that biologic therapies targeting interleukin (IL)-12, IL-23, or IL-17 demonstrate a significant association with decreased serious infection rates among patients aged 66 and older suffering from these chronic conditions.

This groundbreaking analysis, led by Dr. Aaron M. Drucker and his team from the University of Toronto, highlights crucial safety benefits of these medications. Given that older adults are generally at a heightened risk for infections due to age-related immune decline, these findings could represent a pivotal development in treatment strategies for psoriatic diseases.

Study Insights and Methodology

The research team conducted a cohort study utilizing health data from the Ontario population, leveraging the extensive resources available from the Ontario Health Insurance Plan (OHIP) to undertake a rigorous assessment of healthcare records and patient prescriptions. This encompassed a broad sample of Ontario residents who began their first systemic treatment for psoriasis or PsA between April 2002 and December 2020.

The study meticulously categorized systemic treatments into five distinct groups, which included methotrexate, various conventional drugs, anti-tumor necrosis factor (anti-TNF) biologics, other biologics targeting IL-12, IL-23, or IL-17, and tofacitinib. Importantly, the analysis focused on the primary outcome of time until the occurrence of serious infections among the subjects within the cohort.

Among the 11,641 participants, the researchers observed a median age of 71 years, with 53% of them being female. Over a median follow-up period of 4.8 years, they documented 1,967 serious infections across the cohort. Strikingly, the rates of serious infections per 100 person-years revealed significant differences among treatment categories: - Methotrexate: 2.7 - Other older systemic drugs: 2.5 - Anti-TNF biologic drugs: 2.2 - Other biologic drugs (IL-12, IL-23, IL-17 inhibitors): 1.4 - Tofacitinib: 8.9

Key Findings and Implications

Most notably, the analysis indicated that the use of IL-12, IL-23, or IL-17 inhibitors was correlated with a 35% reduction in the risk of serious infections compared to periods where these biologics were not used (RR, 0.65). Conversely, tofacitinib was found to substantially increase the risk (RR, 2.89), suggesting that while it may offer therapeutic benefits, caution is warranted due to its association with higher infection rates.

The researchers emphasized that their findings could guide future approaches to prescribing biologics for older patients. "Our study suggests safety benefits of newer biologics and, among those with psoriatic arthritis, safety advantages associated with anti-TNF biologics. Such insights could be instrumental in informing formulary updates," the team concluded.

As the older population continues to grow, understanding the safety profile of treatments for chronic conditions such as psoriasis and PsA is essential. This study not only sheds light on a significant health issue but also points to the need for ongoing research and potential adjustments in treatment protocols to enhance patient safety and outcomes.
