UPA has shown effectiveness in treating IMIDs like RA, axSpA, PsA, CD, and UC. Chai et al. evaluated evidence from a synthesis of RCTs and provided insights that may guide clinical decision-making and improve treatment outcomes for IMIDs. UPA effectively alleviated symptoms, reduced disease activity, and showed notable benefits in improving quality of life.

Zhang et al. observed that, compared to the control group, ixekizumab was associated with an increased risk of new-onset IBD in psoriasis patients, and that there is insufficient evidence to confirm that ustekinumab, bimekizumab, secukinumab, and brodalumab significantly increase the risk of new-onset IBD. Zhang et al. evaluated the risk of new-onset IBD in psoriasis patients treated with five IL inhibitors (bimekizumab, ixekizumab, secukinumab, brodalumab, and ustekinumab), providing insights to inform clinical decision-making. Additionally, compared to the control group, no significant difference was observed in the risk of diarrhoea as an AE.

The concept of difficult-to-treat disease in rheumatology: where next?

Lancet Rheumatol. 2025;7:e274–89 doi: 10.1016/S2665-9913(24)00340-0

Nagy et al. propose a unifying and holistic framework for understanding and addressing the concept of difficult-to-treat (D2T) disease across rheumatology, integrating cross-disciplinary evidence and recommending its incorporation into future disease management strategies. The D2T state requires a comprehensive, holistic, multidisciplinary approach that considers the specific characteristics of each disease and the personalised needs of the patient.
