Transforming the Care of Psoriatic Disease: the role of Overweight and Obesity-Related Inflammation: Sponsored by Lilly-Transforming the Care of Psoriatic Disease

Video Transcription

Video Summary

The presentation reviewed how obesity and psoriatic disease are closely linked and how that relationship affects treatment outcomes. Mark Lebwohl emphasized that higher BMI is associated with lower PASI-90/100 response rates, slower improvement, and reduced durability of biologic therapy in psoriasis and psoriatic arthritis. He explained that complete skin clearance matters because residual disease is tied to worse quality of life, treatment resistance, discontinuation, and a higher risk of developing psoriatic arthritis.<br /><br />April Armstrong focused on the biology behind the connection. She described adipose tissue as an active endocrine and immune organ, not just energy storage. Visceral fat releases pro-inflammatory adipokines and cytokines that can intensify psoriasis and psoriatic arthritis, while also contributing to cardiovascular and metabolic comorbidities. She reviewed evidence showing obesity is an independent risk factor for developing psoriasis and for progression to psoriatic arthritis.<br /><br />Brad Glick discussed management strategies. He highlighted that guidelines support screening for obesity and metabolic comorbidities, counseling on lifestyle modification, and coordinating care with primary care. Evidence from trials and meta-analyses showed that weight loss, diet changes, exercise, and bariatric surgery can improve psoriasis severity, quality of life, and psoriatic arthritis outcomes, including minimal disease activity.<br /><br />The speakers closed with practical clinic advice: ask permission before discussing weight, use nonjudgmental language, frame obesity as a medical issue, and tailor the conversation to each patient’s readiness. They presented cases showing that treatment should be individualized, but early, aggressive control of both skin disease and obesity-related inflammation may improve long-term outcomes.
