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.      

This study by Harrold, et al. showed that RA patients initiating upadacitinib reported improvements in RAPID3, pain, stiffness, and fatigue as early as Week 1, with 37.5% achieving RAPID3 LDA at Week 12. TNFi-experienced patients had similar outcomes.

Incidence rates for autoimmune diseases increased between 2000 and 2019 in the UK, notably in coeliac disease, Sjogren's syndrome, and Graves' disease. Pernicious anaemia and Hashimoto's thyroiditis had the greatest decrease in incidence. These disorders affected about 10% of the population, with socioeconomic, seasonal, and regional variations observed.

As part of the GBD 2021, the authors provide updated estimates for the global burden of RA. In 2020, approximately 17.6 million people worldwide had RA, with a 14.1% increase in prevalence since 1990. Mortality decreased by 23.8% from 1990 to 2020. The study forecasts an increase in cases to 31.7 million by 2050.

In the UPJOINT open label study, the proportion of patients with PsA, and an inadequate response to csDMARDs or bDMARDs, who achieved minimal disease activity with upadacitinib was in line with the results of previous studies at 24 weeks. No new safety signals were identified.

This study by Bergman, et al. showed that RA patients are significantly more likely to adhere to upadacitinib within the first 12 months of prescription versus adalimumab, baricitinib, and tofacitinib. There was also a significantly lower risk of discontinuation for upadacitinib versus the other treatment prescriptions.

The data gathered in this post-marketing surveillance study aligned with the previously established safety profile of tofacitinib, and reports were found to have consistent safety profiles in the treatment of both patient with PsA and RA. However, the results of this study should be interpreted considering the limitations of post-marketing surveillance studies.

This review by Taylor, et al. reviews the long-term safety and efficacy data for baricitinib. Results from several studies showed that baricitinib has greater efficacy and survival compared to TNF inhibitors, and that the rate of CDAI <10 for baricitinib-treated RA patients increased over the course of seven years. Data also showed that remission rates were higher in real-world evidence than in RCTs.

Results from the 3-year PsABio study demonstrated that, generally, ustekinumab and TNFi treatment led to an improvement in PROs. In coming to this conclusion, researchers aimed to evaluate the real-world effect of ustekinumab or a TNFi on PRO and their association with effectiveness endpoints in PsA patients over 3 years.

Cicirello, et al. present results showing that baricitinib is comparable in treatment persistence with TNF inhibitors. However, treatment persistence up to 24 months was significantly longer for baricitinib, but the effect size of one month is not clinically meaningful.
