Guselkumab treatment exhibited generally comparable and significant pharmacodynamic effects on IL-23/Th17–associated cytokines across participants with PsA who are biologic-naïve or have TNFi-IR. In coming to this conclusion, investigators assessed and compared immunologic differences and associations with clinical response to guselkumab in participants with active PsA who were biologic-naïve or TNFi-IR.

Real-world data from the PsABio study indicated that females with PsA had more severe disease than males before the initiation of treatment. While both genders experienced treatment related improvements, fewer females than males were able to achieve a favourable disease state within 12 months. Treatment discontinuation and switching were also higher in females than males, due to lower efficacy and adverse events.      

Post-hoc analysis of SPIRIT-P1 and SPIRIT-P2 concludes that ixekizumab (IXE) is effective in improving axial symptoms in patients with active PsA presenting with axial manifestations.

The study demonstrated that obesity is a factor that could play a role in treatment decision-making in people living with inflammatory arthritis (IA). It appears that efficacy of TNFi is affected by patients’ weight/BMI in all forms of IA, while this is not the case for TCZ and ABA in RA, as well for IL-17 and IL-23 inhibitors in PsA.

These real-world data from PsABio on gender differences suggest that, at the start of biologic treatment, females have a worse clinical picture of PsA than males. In coming to these conclusions and others, this study sought to investigate effects of gender on disease characteristics and treatment impact in patients with PsA.

The results highlighted the long-term impact of the presence of Achilles enthesitis on the burden of disease. The objectives of this study were to evaluate the impact of Achilles' tendon enthesitis found at baseline during physical examination on the outcome measures after 2 years of follow-up in patients with AS.
