The results from Simon, et al. show that baricitinib treatment correlates with improvements in bone stiffness. Further improvements were also observed at the end of Week 52, with an increase in estimated failure load and no measurable progression in bone erosion being reported.

Reinisch, et al. show that filgotinib treatment has no effect on semen parameters for men with active inflammatory diseases. This contrasts with pre-clinical studies that showed fertility issues in male animals.

Kristensen, et al. used mediation modelling to show that tofacitinib indirectly improved fatigue symptoms via back pain and morning stiffness. This study was carried out using FACIT-F- and BASDAI Q1-based models to determine the relationship between these variables.

Tofacitinib treatment is associated with a significant improvement in CANDEN MRI scores of spinal inflammation in axSpA patients. This study by Østergaard, et al. also validates the CANDEN MRI scoring system as an approach for measuring axSpA-associated inflammatory lesions.

Pots hoc analysis of peficitinib Phase 3 trials shows that continued treatment with peficitinib up to Week 52 is linked to improved remission rates in Asian patients with RA.

Pots hoc analysis of safety data in patients with RA at increased risk of CV events from the upadacitinib SELECT phase III RA clinical programme helps to contextualise the overall risk profile of upadacitinib.

Upadacitinib significantly improved patient-reported outcomes in AxSpA patients with bDMARD-IR after 14 Weeks of treatment. There were notable improvements in disease activity, pain, fatigue, function, HRQoL, and work productivity.

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.

A prospective observational study showed that recombinant zoster vaccine (RZV) immunogenicity is not impaired in RA patients on JAK inhibitors or anti-cellular bDMARDs.

Investigators from a phase 2 study concluded that further investigation with BMS-986142 (a novel BTK) in people with RA is not necessary.
