New work from Semmelweis University, published in Nature Reviews Rheumatology and The Lancet Rheumatology, suggests that persistent rheumatoid arthritis symptoms are not always driven by inflammation alone. The researchers examined how depression, obesity, smoking, sleep problems, and other health conditions relate to difficult-to-treat disease. These factors may do more than accompany rheumatoid arthritis; they may contribute to keeping symptoms active.
Under the widely used "treat-to-target" approach, doctors adjust medication when measurable inflammation stays high. The Semmelweis team argues that the same data can act as an early warning system: if inflammation markers improve but pain and fatigue remain, the symptoms may be driven by chronic pain syndrome, depression, sleep disorders, or obesity. Instead of automatically increasing medication, doctors should investigate what is maintaining the symptoms.
The group's concept of difficult-to-treat disease has already gained international traction, with related publications cited more than a thousand times and the definition now applied beyond rheumatoid arthritis. The researchers are also planning to use AI-based pattern recognition to identify patient subgroups and support more personalized treatment strategies.
