    Dear Editor,

    The recent publication by Brunner et al. [1] on the long-term safety and efficacy of tofacitinib for juvenile idiopathic arthritis (JIA) provides critical insights into the management of this complex condition. Building on their findings, I would like to offer additional perspectives on the implications of these results and suggest areas for future research.

    Firstly, the high incidence of infections observed in the study, particularly upper respiratory tract infections and nasopharyngitis, underscores the need for close monitoring of immunosuppression in pediatric patients. Future research should explore strategies to mitigate these risks, potentially through intermittent dosing schedules or the use of adjunctive therapies that enhance immune function without compromising the efficacy of tofacitinib. Additionally, concerning pediatric patients, it is imperative to assess the impact of long-term tofacitinib treatment on growth and development. Integrating comprehensive evaluations of growth metrics, bone density, and developmental milestones into future studies would ensure that the therapeutic benefits of tofacitinib do not adversely affect physiological development.

    Second, we suggest the authors conduct subgroup analyses based on genetic, demographic, and disease severity indicators so that future research can identify which patients are most likely to benefit from tofacitinib, thereby refining patient selection criteria and enhancing tr...
