A groundbreaking study has revealed that older adults suffering from psoriatic disease may experience significantly lower risks of serious infections when treated with biologics targeting interleukin (IL)-12, IL-23, or IL-17. Published in JAMA Dermatology, this pivotal research shows that biologics not only enhance treatment effectiveness but also reduce hospitalization rates due to infections compared to traditional systemic treatments.

Researchers aimed to address a crucial gap in treatment guidelines for older patients, a demographic particularly vulnerable to infection-related complications. They underscored the necessity for more robust data on the relative risks associated with various systemic treatments for psoriasis and psoriatic arthritis in older adults, many of whom suffer from moderate to severe disease requiring intensive management.

The study used comprehensive health administrative data from Ontario, Canada, covering a period from 2002 to 2021. It examined older adults aged 66 and over who started their first systemic treatment between April 2002 and December 2020. Participants were divided into categories based on their medication: methotrexate, older systemic drugs, anti-tumor necrosis factor (anti-TNF) biologics, and more modern biologics aimed at IL-12, IL-23, and IL-17. The analysis focused on serious infections, particularly hospital admissions for infectious causes, up to March 2021.

Among the 11,641 older adults analyzed, the research noted that over half were female, with an average age of 71. During an average follow-up of about 4.8 years, 1,967 serious infections were documented. The findings were striking: the serious infection incidence rate showed that those on methotrexate had 2.7 incidents per 100 person-years, while anti-TNF biologics had a slightly lower rate of 2.2. In contrast, biologics targeting IL-12, IL-23, or IL-17 reported just 1.4 incidents, suggesting a compelling advantage for these newer therapies. Alarmingly, tofacitinib was associated with a staggering infection rate of 8.9.

The study's detailed multivariable-adjusted analysis revealed that while older systemic treatments and anti-TNF biologics did not carry a significant risk for infections, the biologics specifically targeting IL-12, IL-23, and IL-17 were linked to a remarkable 35% reduction in infection risk. In stark contrast, tofacitinib posed nearly three times the risk of serious infections compared to baseline treatments.

Despite the promising results, the study's authors raised important caveats. The cohort primarily consisted of older patients with multiple health issues, a group typically underrepresented in clinical trials, potentially skewing results. Moreover, the lack of data on race and ethnicity might also limit the findings' applicability. They acknowledged the possibility of a "healthy user bias," which could further influence the perceived benefits of the newer biologics.

Notwithstanding these limitations, the authors argue that the compelling evidence supports a shift towards biologics targeting IL-12, IL-23, and IL-17 as the preferred treatment for older adults with psoriatic disease. They conclude that these therapies, paired with their proven efficacy in psoriasis management, could revolutionize care strategies for this vulnerable population and significantly enhance patient outcomes.

This study sets a new precedent, prompting healthcare providers to reconsider treatment protocols and prioritize biologics that minimize risks for the elderly—a game-changer for many battling psoriatic disease.

For those keeping an eye on developments in psoriatic disease management, this study underscores how innovative treatments are reshaping patient care in positive and potentially life-saving directions. Stay tuned for more updates on breakthroughs in dermatological research!
