Negative effect of lockdown on juvenile idiopathic arthritis patients.

We have found a significant increase in JIA reactivations in the period March-July 2020 compared to the same interval of 2018 and 2019. This increase may have been caused by poor compliance with background treatment, as documented in 7/19 JIA patients reactivated, and by a greater interval in follow-up checks. Therefore, it is necessary, in occasion of a new pandemic and lockdown, to implement greater controls using more appropriate telemedicine tools. Key Points • COVID-19 pandemic lockdown had a negative effect on the follow-up of JIA patients. • A significant increase in JIA reactivations was found during the lockdown. • Poor therapeutic compliance and follow-up checks have been proven during the lockdown. • It is necessary to improve telemedicine tools and scientific information during a pandemic and lockdown.
