Tanaka et al. observed that in Japanese patients with rheumatoid arthritis treated with tofacitinib, those with absolute lymphocyte counts (ALCs) <0.5x10³ cells/mm³ had a higher risk of serious infections and herpes zoster events compared to patients with higher ALC levels. This threshold may help identify increased infection risk in this population

The outcomes of children born to mothers with autoimmune rheumatic diseases

Lancet Rheumatol 2024:S2665-9913(24)00096-1 doi: 10.1016/S2665-9913(24)00096-1 Epub ahead of print

This Series paper by Andreoli, et al. provides a comprehensive overview of the literature for pregnancy outcomes for mothers with autoimmune rheumatic disease, and provides guidance on discussing these topics with patients. They also provide a list of frequently asked questions related to pregnancy and children by women with autoimmune rheumatic diseases.

Burmester, et al. found that long-term filgotinib exposure was well tolerated in patients with moderate-to-severe active RA, with a stable rate of TEAEs over time. However, potential dose-dependent relationships for herpes zoster infections, malignancies and all-cause mortality were observed in patients aged ≥65 years, indicating the potential impact of age on the safety profile of Filgotinib. Therefore, some patients aged ≥65 years may benefit from the filgotinib 100 mg dose option.

Results of this analysis by Hernández-Cruz, et al. show that infections, herpes zoster and gastrointestinal AEs in patients with RA tended to be more frequent with JAKi treatment versus TNFi. They also found that treatment persistence was similar with JAKi and TNFi in patients with RA and axSpA, and only slightly higher for TNFi in patients with PsA.

No new safety signals were found in the three-year safety data on bimekizumab for plaque PsO. Additionally, incidence of oral candidiasis significantly decreased with each subsequent year.

Efficacy and safety of JAK inhibitors in rheumatoid arthritis: update for the practising clinician

Nat Rev Rheumatol 2024;20(2):101–115 DOI: 10.1038/s41584-023-01062-9

The observed benefit:risk ratio strongly favours JAKi use in the majority of patients, and HCPs should consider and adhere to guidance on high-risk patients where applicable. Szekanecz et al summarised the safety and efficacy of approved JAKis tofacitinib, baricitinib, upadacitinib, and filgotinib to aid in clinical decision making.
